Mustafa BORAN* Çanakkale Onsekiz Mart Üniversitesi, İlahiyat Fakültesi, İslam Hukuku Anabilim Dalı -- , E-mail: mustafa.boran@comu.edu.tr Orcid: https://orcid.org/0000-0001-2345-6789 İslam hukukunda avlanmak Kitap, Sünnet ve icmâ ile mubah sayılmıştır. Mubah; yapılmasında bir sakınca olmayan, yapılmadığı zaman da bir günah terettüp etmeyen hususlardır. Meşru ölçüler içerisinde avcılık caiz görülmüştür. Ancak gereksiz yere avlanmak, istifade kastı olmadan av hayvanını vurmak caiz görülmemiştir. Fıkıh kitaplarımızda av ve avcılık ile ilgili hükümler genişçe ele alınmıştır. Avlanacak hayvan, avlanan kimse, eğitilmiş hayvan ile avcılık konularında hükümler belirlenmiştir. Avcılığın hayvan kesimi ile ilgisi vardır. Dinimiz öldürmeyi değil, yaşatmayı esas alır. Hayvanların da belirli bir süre yaşama hakkı vardır. Ayrıca dinimizde hayvan sevgisi, hayvanlara ve bütün canlılara merhamet esas alınmıştır. Avcılığa bu esaslar çerçevesinde sınırlı izin verilmiştir. Bugün modern kanun metinlerinde de avcılık konusunda sınırlamalar, belli şartlar konulmuştur. Avcılığa ruhsat verilmesinin en önemli sebeplerinden birisi gıda ihtiyacını karşılamaktır. Günümüzde avcılık ile et ihtiyacını karşılamak pek mümkün görünmemektedir. Tam tersine bugün yaban hayvanlarının yaşam alanlarına müdahale, aşırı avlanma gibi sebeplerle yaban hayatı tehlikeye girmiştir. Bazı hayvan türlerinin nesli tükenmiş, bazısı da tükenmek üzeredir. Bu sebeple kara avcılığı sınırlı kalmıştır. Denizlerde su ürünlerinin birçoğu aşırı avlanma ile tehlike altında kalmıştır. Ayrıca denizlerde meydana gelen aşırı kirlilik deniz ürünlerine de yansımaktadır. Bu sebeple çevreyi temiz tutmak ve atık suları ileri derecede arıtmak lazım gelmektedir. Günümüzde avcılık konusunda meydana gelen bu gelişmeler çerçevesinde alan son derece daralmıştır. Bu makalede, av ve avcılık konuları İslam hukuku çerçevesinde ele alınarak hayvan sevgisi ve çevre gibi güncel bazı değerlendirmelere de kısaca yer verilmiştir. In Islamic law, hunting is permitted by the Book, Sunnah, and Ijma. Licit means following Islamic law and applying strict conformity to the provisions of and what is regulated by Islamic law so that the people are allowed to do or not to do anything. Concerning the legitimate limits, hunting is justified. In contrary to this, gratuitously hunting is not approved, as well as hitting the games randomly. Our fiqh acts comprehensively evaluate the game and hunting and describe the judgments on the game to be hunted, hunter, porting animal, and hunting. Hunting subject is related to slaughtering. Our religion’s idea is to make, not to kill any living things. The animals also have the right to live for a certain period. In addition to that, our religion is grounded on the facts “animal welfare” and “treating all beings with mercy .”Therefore, hunting is restricted following these principles under the limitations and terms set out by the current laws and regulations by the sharia. One of the most legitimate reasons for hunting is to meet the need for food. Based on the current facts, hunting cannot meet the need of meat today. However, on the contrary, the hunters endanger the wildlife by destroying animal habitats with excessive hunting. Some animal species are critically endangered while others are virtually extinct, thereby restricting ground of hunting. Again, overfishing is the most severe threat to the fish species too. Additionally, sea pollution leads to the death of sea animals. Therefore, keeping the environment clean and treating wastewater efficiently have gained significant importance in today’s world. Overall, hunting today is negatively affected by these realities. In this article, the game and hunting issues are discussed within the framework of Islamic law, and some current assessments concerning the animal love and environmental protection are also briefly mentioned.

Safety-critical systems such as Advanced Driving Assistance Systems and Autonomous Vehicles require redundancy to satisfy their safety requirements and to be classified as fail-operational. Introducing redundancy in a system with high data rates and processing requirements also has a great impact on architectural design decisions. The current self-driving vehicle prototypes do not use a standardized system architecture but base their design on existing vehicles and the available components. In this work, we provide a novel analysis framework that allows us to qualitatively and quantitatively evaluate an in-vehicle architecture topology and compare it with others.With this framework, we evaluate different variants of two common topologies: domain and zone-based architectures. Each topology is evaluated in terms of total cost, failure probability, total communication cable length, communication load distribution, and functional load distribution.We introduce redundancy in selected parts of the systems using our automated process provided in the framework, in a safety-oriented design process that enables the ISO26262 Automotive Safety Integrity Level decomposition technique. After every design step, the architecture is re-evaluated. The advantages and disadvantages of the different architecture variants are evaluated to guide the designer towards the choice of correct architecture, with a focus on the introduction of redundancy.

The quality of Norwegian cold pressed camelina oil for human consumption and fish feed production, with a special focus on plant rest materials, natural antioxidants, and oxidation products is studied. Both crude oil with plant rest materials (CCO) and centrifuged oil (CO) were highly unsaturated with 39.4% (w/w) α-linolenic acid. The oils were oxidatively stable for 12 months at long-term storage conditions at 4 °C. Lipid oxidation was observed in CO but not in CCO, between 6 and at 9 months at 20 °C. This difference was even higher at accelerated conditions at 40 °C with an increase in PV, AV, and secondary oxidation products and a decrease in tocopherols after 2 weeks in CO but not in CCO. This indicates there are natural antioxidants with stronger antioxidant capacity than tocopherols in association with the plant rest materials in CCO. The polyphenol rutin with antioxidative properties might be a good candidate but needs further studies.

- Abstract
Background Device-based fully automatic pacing capture detection is useful in clinical practice and important in the era of remote care management. The main objective of this study was to verify the effectiveness of the new ACAP Confirm® algorithm in managing atrial capture in the medium term in comparison with early post-implantation testing. Methods Data were collected from 318 patients (66% male; mean age, 73±10 years); 237 of these patients underwent device implantation and 81 box changes in 31 Italian hospitals. Atrial threshold measurements were taken manually and automatically at different pulse widths before discharge and during follow-up (7±2 months) examination. Results The algorithm worked as expected in 73% of cases, considering all performed tests. The success rate was 65% and 88% pre-discharge and during follow-up examination ( p <0.001), respectively, in patients who had undergone implantation. We did not detect any difference in the performance of the algorithm as a result of the type of atrial lead used. The success rate was 70% during pre-discharge testing in patients undergoing device replacement. Considering all examination types, manual and automatic measurements yielded threshold values of 1.07±0.47 V and 1.03±0.47 V at 0.2-ms pulse duration ( p =0.37); 0.66±0.37 V and 0.67±0.36 V at 0.4 ms ( p =0.42); and 0.5±0.28 V and 0.5±0.29 V at 1 ms ( p =0.32). Conclusions The results show that the algorithm works before discharge, and its reliability increases over the medium term. The algorithm also proved accurate in detecting the atrial threshold automatically. The possibility of activating it does not seem to be influenced by the lead type used, but by the time from implantation. [ABSTRACT FROM AUTHOR]

Sun Q and Wu X
- Abstract
There is a phenomenon of attaching importance to technique and neglecting emotion in the training of sports dance (SP), which leads to the lack of integration between movement and emotion and seriously affects the training effect. Therefore, this article uses the Kinect 3D sensor to collect the video information of SP performers and obtains the pose estimation of SP performers by extracting the key feature points. The Arousal-Valence (AV) emotion model, based on the Fusion Neural Network model (FUSNN), is also combined with theoretical knowledge. It replaces long short term memory (LSTM) with gate recurrent unit (GRU), adds layer-normalization and layer-dropout, and reduces stack levels, and it is used to categorize SP performers' emotions. The experimental results show that the model proposed in this article can accurately detect the key points in the performance of SP performers' technical movements and has a high emotional recognition accuracy in the tasks of 4 categories and eight categories, reaching 72.3% and 47.8%, respectively. This study accurately detected the key points of SP performers in the presentation of technical movements and made a major contribution to the emotional recognition and relief of this group in the training process., Competing Interests: The authors declare there are no competing interests., (©2023 Sun and Wu.)

California legislators have reintroduced a bill that would give politicians, rather than state regulators, the final say on whether safety operators should be required on autonomous heavy-duty trucks. This move has caused tensions between the AV industry and the public, following accidents involving driverless cars. The bill aims to provide more oversight over the AV sector and aligns with another bill supported by the Teamsters, which calls for local ordinances to allow autonomous vehicles to operate in specific areas. The Autonomous Vehicle Industry Association argues that both truck drivers and autonomous trucks can coexist and support the state's industries. [Extracted from the article]

An effective implementation approach is crucial for successful integration of structured risk assessment instruments into practice. This qualitative study explored barriers and facilitators to the implementation of the Short-Term Assessment of Risk and Treatability: Adolescent Version (START:AV) in a Dutch residential youth care service. Perceptions of staff members from various disciplines were gathered through focus group interviews at three consecutive occasions. After inductive coding of the interview extracts using thematic analysis, the identified codes were linked to the consolidated framework for implementation research. Through this framework, factors that influence an implementation project can be organized into multiple domains and constructs. In the present study, staff members described implementation barriers related to characteristics of the risk assessment instrument, staff, and the implementation process. In addition, features of the setting were frequently mentioned as hindering the implementation, such as hierarchy, culture, communication, as well as implementation climate and readiness for change. Staff members also identified multiple facilitators, such as experienced advantages of the START:AV compared to the previous risk assessment practice and positive beliefs about the instrument. The article concludes with recommendations for successful implementation of structured risk assessment instruments in forensic-clinical practice.

Halk anlatmaları hayata dair her unsuru içerir. Halk anlatmalarının konu, motif, sembol, tip gibi özelliklerinde hayattaki tüm olgularla ilgili meseleler, semboller ve mesajlar vardır. İnsanlığın geçmişten günümüze anlattığı mit, efsane, rivayet gibi anlatmalar insan, dünya ve gerçek hayatla ilgili sembolik ve işlevsel içeriklere sahiptir. İnsanın doğayla ilişkisi, insan karşısında doğa veya doğa karşısında insan gibi temalar bu anlatma türlerinin önemli konuları arasındadır. Edebî metinlerdeki insan ve doğa ilişkilerini incelemek amacıyla ekoeleştiri, biyoetik veya ekofolklor gibi yaklaşımlar ortaya atılmıştır. Bu yaklaşımlar sözlü ve yazılı anlatmalardaki çevre, tabiat, hayvan kavramlarını ele almıştır. Sözlü kültürdeki ürünlerde bu kavramların mitik ve kutsal niteliklerinin işlevsel bir boyutu vardır. Bu işlevsel boyut aslında dünyevidir ve anlatmaların sahibi olan topluluk, bu kavramlarla ilgili düşüncelerini metinlerle aktarır, bu şekilde dünyaya ve hayata yönelik kavramlarını, uyarılarını, doğru ve yanlış algılarını ortaya koyar. Türk Dünyası anlatmaları Türklerin geçmişten günümüze yaşadığı coğrafya ve tarihî süreçlerle ilgili bir şekilde ekofolklor bakımından incelenecek çok sayıda metne sahiptir. Azerbaycan Türk sahası da Türk Dünyası’ndaki coğrafî konumu ve tarihî derinliğiyle Türk kültürünün farklı yönlerini gösterebilecek niteliklere sahiptir. Bu düşünceden hareketle bu makalede Azerbaycan Türklerine ait efsane metinlerini ekofolklor bakış açısıyla inceledik. Makalede ilk olarak ekoeleştiri ve biyoetik kavramlarına kısaca değindik. İkinci olarak ekofolklor kavramına geleneksel ekolojik bilgi ile çevre ve folklor ilişkisi bağlamında değindik, Türk halk anlatmalarının ekoeleşirel ve biyoetik incelemelerinden örnekler gösterdik. Ardından Azerbaycan Türk sahasından derlenip yazıya geçirilmiş efsane metinlerinde “av”, “su” ve “ağaç” kavramlarını ekofolklor bakış açısıyla inceledik. Bu incelemede mitik düşünce, kutsallık, mekân, etik ve çevrecilik kavramlarından faydalandık. Bununla birlikte metinleri Türk kültürünün tarih ve coğrafya özelliklerini göz önünde bulundurduk ve metinleri Türk kültür kodları açısından da yorumladık. İncelememizde kuramsal olarak ekoeleştiri, biyoetik, mekân edebiyatı ve işlevsel teorinin bakış açılarından faydalandık. Sonuç olarak belli sayıda efsane metninden hareketle Azerbaycan Türk efsanelerindeki insan ve doğa ilişkisinin Türk kültürünün doğaya karşı görüşlerini bütüncül bir şekilde yansıttığını, efsanelerdeki unsurların bazı noktalardan ortaklaştığını, efsane metinlerinin doğaya karşı çeşitli uyarılarda bulunup etik meselelere değindiğini ve “çevreci” metinler olduklarını ortaya koyarak tahlil ettik.

Yazılan bu tez insanlık tarihinde mühim bir beslenme faaliyeti olan avcılığın Selçuklu Anadolusu’nda (1075-1318) uygulanmasını konu edinmektedir. Bilindiği üzere Anadolu Selçuklularının politik, diplomatik alanlarına dair çalışmalar yapılmasına karşın devleti ve o dönemki toplumu anlamada önemli bir konu olan avcılığa dair çalışmalarda eksiklikler vardır. Bu kapsamda dönemin vakayinameleri, edebî eserleri ve çağın sanatsal ürünleri incelendiğinde, Anadolu’da avcılığa dair zengin bir malzeme olduğu kanaatine varılmış; tez de bu doğrultuda şekillenmiştir. This thesis is about hunting in Seljuk Anatolia, which is an important activity in the history of humanity (1075-1318). Although there is research on the Anatolian Seljuks political and diplomatic fields, there are deficiencies in the studies on hunting, which is an important aspect of understanding the state and society at the time. When the period's chronicles, literary works, and artistic objects of the time were analyzed in this context, it was concluded that Anatolia had a treasure of hunting material, and the thesis was shaped in this direction.

In this paper, the effect of oxide-semiconductor interface trapped charges on the performance of 22-nm Fully Depleted Silicon on Insulator (FDSOI) Negative Capacitance FET (NCFET) has been systematically investigated. Metal-Ferroelectric-Metal-Insulator-Semiconductor (MFMIS) type NCFET with zirconium doped HfO 2 (HZO) as the ferroelectric material is considered for this work. The simulation of the underlying Metal-Insulator-Semiconductor (MIS) structure has been carried out in a well-calibrated TCAD environment to extract the gate charge. Which is subsequently used to solve 1D Landau-Khalatnikov (1D-LK) model to find the voltage across ferroelectric capacitor. The presence of trap charges is unavoidable in modern devices, which affects the charge balance equation as well as the performance & reliability of the device. NCFET being one of the potential candidates to be adopted by industry for ultra-low power applications in the future according to the International Roadmap for Devices and Systems (IRDS), investigation of trap charges becomes crucial. Due to its multilayer stacking, the transfer characteristics are analyzed for various ferroelectric thicknesses with exhibition of an intersection point, which is demonstrated for the first time. Simulation of variation of device performance metrics like minimum sub-threshold swing (min. SS), transconductance (g m), off-state drain current (I off) & amplification factor (A V) are analyzed and compared for various interface trapped charge densities. It is predicted that the device performance either enhances or degrade depending on the type of trapped charges present. • The effect of oxide-semiconductor interface induced trapped charges is investigated. • MFMIS type FDSOI NCFET with Zr doped HfO 2 (HZO) as the ferroelectric is considered. • Device performance metrics are evaluated and compared for various interface trapped charge densities. • The stabilized point analysis pave path to overcome the challenges of mismatch in ferroelectric thickness. • It also takes simulation steps closer to the experiment by inclusion of the innate interface trap charges.

Observable lip movements of the speaker influence perception of auditory speech. A classical example of this influence is reported by listeners who perceive an illusory (cross-modal) speech sound (McGurk-effect) when presented with incongruent audio-visual (AV) speech stimuli. Recent neuroimaging studies of AV speech perception accentuate the role of frontal, parietal, and the integrative brain sites in the vicinity of the superior temporal sulcus (STS) for multisensory speech perception. However, if and how does the network across the whole brain participates during multisensory perception processing remains an open question. We posit that a large-scale functional connectivity among the neural population situated in distributed brain sites may provide valuable insights involved in processing and fusing of AV speech. Varying the psychophysical parameters in tandem with electroencephalogram (EEG) recordings, we exploited the trial-by-trial perceptual variability of incongruent audio-visual (AV) speech stimuli to identify the characteristics of the large-scale cortical network that facilitates multisensory perception during synchronous and asynchronous AV speech. We evaluated the spectral landscape of EEG signals during multisensory speech perception at varying AV lags. Functional connectivity dynamics for all sensor pairs was computed using the time-frequency global coherence, the vector sum of pairwise coherence changes over time. During synchronous AV speech, we observed enhanced global gamma-band coherence and decreased alpha and beta-band coherence underlying cross-modal (illusory) perception compared to unisensory perception around a temporal window of 300-600 ms following onset of stimuli. During asynchronous speech stimuli, a global broadband coherence was observed during cross-modal perception at earlier times along with pre-stimulus decreases of lower frequency power, e.g., alpha rhythms for positive AV lags and theta rhythms for negative AV lags. Thus, our study indicates that the temporal integration underlying multisensory speech perception requires to be understood in the framework of large-scale functional brain network mechanisms in addition to the established cortical loci of multisensory speech perception.

In the present investigation, some key fuel properties such as acid value (AV), iodine value (I), peroxide value (PV), water content (WC), and flash point (FP) of cottonseed oil methyl esters (CSOME) and palm stearin methyl esters (PSME) biodiesels, and their blends with petroleum diesel are estimated as per American Society for Testing Materials (ASTM) and American Oil Chemists Society (AOCS) methods. The variations of all the properties with blends have been analyzed as a function of fatty acid profile of biodiesels. The fatty acid profile of the biodiesels is determined using gas chromatography–mass spectrometer (GC-MS) method. CSOME biodiesel is rich in unsaturated fatty acid methyl esters (FAME) and PSME in saturated FAME. Both the biodiesel blends have shown different types of variations for different properties.

Presently, viral vectors are widespread biological products, some of which have already been commercialized. They are derived from viruses modified to render them apt for gene transfer and safe for clinical purposes. They have several applications including the treatment of rare and acquired diseases as well as vaccination. This review briefly presents the four viral vectors mainly used currently (adenoviral, adeno-associated viral, γ-retroviral, and lentiviral vectors), as well as their biology and manufacturing issues. Furthermore, their applications in gene therapy/gene addition and protein transfer approaches are described. [ABSTRACT FROM AUTHOR]

Environmental pollution and energy use in the light-duty transportation sector are currently regulated through fuel economy and emissions standards, which typically assess quantity of pollutants emitted and volume of fuel used per distance driven. In the United States, fuel economy testing consists of a vehicle on a treadmill, while a trained driver follows a fixed drive cycle. By design, the current standardized fuel economy testing system neglects differences in how individuals drive their vehicles on the road. As autonomous vehicle (AV) technology is introduced, more aspects of driving are shifted into functions of decisions made by the vehicle, rather than the human driver. Yet the current fuel economy testing procedure does not have a mechanism to evaluate the impacts of AV technology on fuel economy ratings, and subsequent regulations such as Corporate Average Fuel Economy targets. This paper develops a method to incorporate the impacts of AV technology within the bounds of current fuel economy test, and simulates a range of automated following drive cycles to estimate changes in fuel economy. The results show that AV following algorithms designed without considering efficiency can degrade fuel economy by up to 3%, while efficiency-focused control strategies may equal or slightly exceed the existing EPA fuel economy test results, by up to 10%. This suggests the need for a new near-term approach in fuel economy testing to account for connected and autonomous vehicles. As AV technology improves and adoption increases in the future, a further reimagining of drive cycles and testing is required. [ABSTRACT FROM AUTHOR]

COMMERCIAL real estate ,AUTONOMOUS vehicles - Abstract
Hardly a day goes by without the release of a handful of news stories about autonomous vehicles (or AVs for short). The proverbial "tipping point" of awareness has been reached in the public consciousness as AV technology is quickly becoming the new focus of firms from Silicon Valley to Detroit and beyond. Automation has, and will continue to have far-reaching implications for many human activities, but for driving, the technology is here. Google has been in talks with automaker Ford (1), Elon Musk has declared that Tesla will have the appropriate technology in two years (2), GM is paired-up with Lyft (3), Uber is in developmentmode (4), Microsoft and Volvo have announced a partnership (5), Apple has been piloting its top-secret project "Titan" (6), Toyota is working on its own technology (7), as is BMW (8). Audi (9) made a splash by sending a driverless A7 concept car 550 miles from San Francisco to Las Vegas just in time to roll-into the 2016 Consumer Electronics Show. Clearly, the race is on.

- Abstract
The effect of the roasting process on the quality of hazelnuts ( Corylus avellana L.) lipidic fraction was investigated by pressure differential scanning calorimetry (PDSC) and middle Fourier transform infrared (MID-FT-IR) spectroscopy. The data obtained were referred to and related with fatty acid composition, free fatty acids content, peroxide value, anisidine value and tocopherols concentration measured by standard techniques. These methods were used to decipher between the roasted hazelnuts (shelled and in-shell) treated in different thermal conditions (100 °C, 130 °C and 160 °C) and time (10, 30 and 60 min). The results of free fatty acids (FFA), peroxide value (PV) and anisidine value remained low for all roasting conditions applied and were within quality requirement ranges. The shell left on hazelnuts during the roasting process limited hazelnuts oxidative deterioration, hence it showed protective function. Minor changes occurred in the fatty acid and tocopherol contents and compositions. PDSC, as an appropriate unbiased method for assessing the oxidative stability, revealed a slight elevation of oxidative stability as the temperature and time of the roasting process increased ( p < 0.05). Discriminant models constructed with the use of principal components (PC) procedure confirmed the ability of MID-FT-IR to monitor the roasting process within a certain range of temperature and time applied.

- Abstract
Safety-critical systems such as Advanced Driving Assistance Systems and Autonomous Vehicles require redundancy to satisfy their safety requirements and to be classified as fail-operational. Introducing redundancy in a system with high data rates and processing requirements also has a great impact on architectural design decisions. The current self-driving vehicle prototypes do not use a standardized system architecture but base their design on existing vehicles and the available components. In this work, we provide a novel analysis framework that allows us to qualitatively and quantitatively evaluate an in-vehicle architecture topology and compare it with others.With this framework, we evaluate different variants of two common topologies: domain and zone-based architectures. Each topology is evaluated in terms of total cost, failure probability, total communication cable length, communication load distribution, and functional load distribution.We introduce redundancy in selected parts of the systems using our automated process provided in the framework, in a safety-oriented design process that enables the ISO26262 Automotive Safety Integrity Level decomposition technique. After every design step, the architecture is re-evaluated. The advantages and disadvantages of the different architecture variants are evaluated to guide the designer towards the choice of correct architecture, with a focus on the introduction of redundancy.

- Abstract
Bakgrund Sverige har efter lång samhällsutveckling fått lagkrav på grundskolemåltider som ska vara gratis och näringsrik. Offentlig måltidsservice utvecklar de måltiderna med införande av vegetarisk kost utifrån riktlinjer från politik och myndigheter. Det finns utmaningar med införandet och olika kommuners skolbarn har olika acceptansgrad. Att undersöka beslutsfattares erfarenheter och upplevelser kan ge ökad kunskap om olika strategier för förändringsarbete. Syfte Att undersöka upplevelser och erfarenheter vid införandet av vegetarisk kost i skolmåltiden hos personer i beslutsfattande ställning inom måltidsverksamheter i grundskolan. Metod Kvalitativa semistrukturerade intervjuer genomfördes på distans med 17 deltagare från olika kommuner inom Sverige. Intervjuerna spelades in via digitala datorappar och telefon, transkriberades och genomgick kvalitativ innehållsanalys.Resultat Implementering av vegetarisk kost mötte varierat motstånd beroende av hur implementeringen skett. I majoriteten av fallen infördes vegetarisk kost för att minska klimat- och miljöpåverkan hos kommunerna och oftast infördes lakto-ovo vegetarisk kost. I allmänhet upplevde deltagarna att införandet av vegetarisk kost uppmuntrades från politiskt håll. När vegetarisk infördes i form av en helvegetarisk dag i veckan var det mer kritik än när implementeringen var i form av ett dagligt vegetariskt alternativ. Informanterna upplevde att elever och föräldrar haft en negativ reaktion till ordet “vegetarisk” i samband med skolmat. Slutsats Erfarenheterna och upplevelserna hos personerna i beslutsfattande ställning såg olika ut. Det varierade från näst intill inga problem till stora och allvarliga problem. Det var kopplat till hur implementeringen gått till, där de som hade stora problem hade implementerat för mycket för snabbt. I kontrast var det färre problem för de som implementerade vegetariskt kost långsammare., Background Sweden has after a long municipality development gained legal requirement that elementary school food must be cost-free and nutritional. Public food service develops those meals by implementation of vegetarian diets from the guidelines of politics & authorities. There are challenges with implementation and different municipalities schoolchildren has more different stages of acceptance. To research decisionmakers experiences can give increased understanding about different strategies for work of change. Objective To investigate experiences within people in decision-making positions in public food service in elementary school with the implementation of vegeterian diets in the school meal. Method Qualitative semi-structured interviews were completed on distance with 17 participants from different municipalities in Sweden. The interviews were recorded by digital computer applications and telephone. Recorded interviews were transcribed and underwent analysed qualitative content analysis. Results The results show that implementation of a vegetarian diet that happen faster and in larger scale receives more criticism. In most cases, the implementation of vegetarian diet was due to climate and environmental improvement reasons in the municipality. In general, the experience of implementing vegetarian diet were encouraged by the local politics. If the first implementation were in the form of exclusive vegetarian diet once a week, more criticism was received than if implementation were in the form of a daily vegetarian alternative. Lacto-ovo were implemented in the overwhelming majority by participants. Conclusion The study reflections could develop understanding of implementation. The most distinct findings were the community profit and the criticism that resided from rushed implementation as well with lack of staff competence. The shortcomings were related to insufficient guidelines from the authorities for different municipalities needs. The most appropriate

- Abstract
Introduction: In current urban traffic, pedestrians attempting to cross the road at un-signalized locations are thought to mostly use implicit communication, such as deceleration cues, to interpret a vehicle's intention to yield. There is less reliance on explicit driver- or vehicle-based messages, such as hand/head movements, or flashing lights/beeping horns. With the impending deployment of Automated Vehicles (AV), especially those at SAE Level 4 and 5, where the driver is no longer in control of the vehicle, there has been a surge in interest in the value of new forms of communication for AVs, for example, via different types of external Human Machine Interfaces (eHMIs). However, there is still much to be understood about how quickly a novel eHMI affects pedestrian crossing decisions, and whether it provides any additional aid, above and beyond implicit/kinematic information from the vehicle. The aim of this between-participant study, funded by the H2020 interACT project, was to investigate how the combination of kinematic information from a vehicle (e.g., Speed and Deceleration), and eHMI designs, play a role in assisting the crossing decision of pedestrians in a cave-based pedestrian simulator. Method: Using an existing, well-recognized, message for yielding (Flashing Headlights - FH) as a benchmark, this study also investigated how quickly a novel eHMI (Slow Pulsing Light Band – SPLB) was learned. To investigate the effect of eHMI visibility on crossing decisions, the distance at which each eHMI was perceivable was also measured. Results: Results showed that, compared to SPLB, the FH led to earlier crossings during vehicle deceleration, especially at lower approaching speeds, and smaller time gaps. However, although FH was visible earlier than SPLB, this visibility does not appear to be the only reason for earlier crossings, with message familiarity thought to play a role. Participants were found to learn the meaning conveyed by FH relatively quickly, cross

Febrile seizures (FS) affect up to 5% of children. The pathogen etiology in regard of viral loads has never been investigated. In a prospective cohort study we investigated the correlation between virus type and quantity in nasopharyngeal aspirates (NPAs) and the clinical characteristics in pediatric patients with a FS. From January 2014 to April 2016, 184 children with a FS were prospectively enrolled. The mean age of all included children was 26.7 ± 18.3 months with a male to female ratio of 1.4:1. Males with an acute disease and a short duration or absence of prior symptoms had a higher risk for complex FS. The majority of patients with FS presented with a generalized convulsion (180, 98%) and was admitted to hospital (178, 97%). Overall, 79 (43%) single and in 59 (32%) co-infections were detected. Human herpes virus 6 (HHV6), influenza, adenovirus (AV) and rhinovirus (RV) were the dominant pathogens, all detected with clinically significant high viral loads. HHV6 positive cases were significantly younger and less likely to have a positive family/personal history for FS. Influenza positives showed a higher rate of complex seizures, lower leukocyte and higher monocyte counts. AV positive cases were more likely to have a positive family history for FS and showed higher C-reactive protein values. In conclusion, a high viral load may contribute to the development of a FS in respiratory tract infections.

Future automotive systems, with Advanced Driving Assistance Systems and Autonomous Driving functionalities, will require fail-operational electronic systems. To achieve that, redundancy is a necessary technique, like in many other fields such as aviation. Moreover the applications have different safety requirements, from safety-critical related applications, for example for the driver replacement domain, to QoS-oriented applications, for example for the infotainment domain. Redundancy in mixed-criticality systems can be solved by physically separating system resources or by using isolated virtualized environments with e.g. hypervisors. There are costs associated to both solutions. In this work we describe a novel model we use to characterize a mixed-criticality automotive system and the analysis steps to obtain quantified metrics. The quantified metrics include cost, failure probability, total functional and communication loads, and total cable length, to compare the different solutions from a system-level perspective. We analyse the same set of mixed-criticality applications that represent a simplified automotive system in four scenarios. The architecture topology is either domain-based or zone-based, and we use either physical separation or virtualization to provide isolation. The obtained results show how the model and the analysis allows us to understand the trade-offs between the different solutions in specific applications scenarios, and how to vary the metrics used in the analysis to adapt to a different applications scenario.

In contrast to previous works on data augmentation using LIDAR (Light Detection and Ranging), which mostly consider point clouds under good weather conditions, this paper uses point clouds which are affected by spray. Spray water can be a cause of phantom braking and understanding how to handle the extra detections caused by it is an important step in the development of ADAS (Advanced Driver Assistance Systems)/AV (Autonomous Vehicles) functions. The extra detections caused by spray cannot be safely removed without considering cases in which real solid objects may be present in the same region in which the detections caused by spray take place. As collecting real examples would be extremely difficult, the use of synthetic data is proposed. Real scenes are reconstructed virtually with an added extra object in the spray region, in a way that the detections caused by this obstacle match the characteristics a real object in the same position would have regarding intensity, echo number and occlusion. The detections generated by the obstacle are then used to augment the real data, obtaining, after occlusion effects are added, a good approximation of the desired training data. This data is used to train a classifier achieving an average F-Score of 92. The performance of the classifier is analyzed in detail based on the characteristics of the synthetic object: size, position, reflection, duration. The proposed method can be easily expanded to different kinds of obstacles and classifier types.

For solving the optimization problem in vehicle ego-motion estimation in mobile mapping system (MMS) or autonomous vehicle(AV), the relationship between vehicle pose and optical flow is proposed to be utilized and all optical flow vectors are decoupled into 3 translational components, 3 rotational components and 1 depth component. The error influences on single component and combined components to vehicle pose estimation are derived. The validity of error separation models with single or combined components is verified through simulation and real-scene data experiments. The combined components error separation model is employed in the proposed flow-decoupled motion field based pose optimization algorithm for stereo visual odometry. Experiment results illustrate that, in conditions of almost the same calculation efficiency as the initial estimation process, this algorithm can reduce the average lateral direction error from 4.75% to 2.2%, which means the lateral direction error is reduced by 53.6%; and it can reduce the average forward direction error from 2.2% to 1.9%, which means the forward direction error is reduced by 15.4%.The results demonstrate that the lower cumulative error ratio can satisfy the requirement of real-time vehicle ego-motion estimation in low power dissipation and high efficiency situations in integrated navigation.

The automobile industry is faced with societal and market pressures to develop radically innovative cars for the future. The development of the autonomous vehicle (AV) is a strategic innovation in this area. This paper studies whether and how AV-innovation strategies at Tesla, BMW and Toyota are developed by using an open and/or closed innovation paradigm. More than ever, it appears that R&D departments of car manufacturers employ a combination of a closed and an open innovation strategy. In order to nurture their AV innovation strategy, they strategically decide which innovations to adopt from outside, and which parts of the R&D process to keep in-house. This paper presents and discusses the combined closed-open AV-innovation strategies used by three dominant car producers. It provides an insight in how they aim to gain a first-to-market position and sustainable competitive advantage in a new market segment of a highly saturated market.

- Abstract
As passenger vehicle technologies have advanced, so have their capabilities to avoid obstacles, especially with developments in tires, suspensions, steering, as well as safety technologies like ABS, ESC, and more recently, ADAS systems; however, environments around passenger vehicles have also become more complex, and dangerous. As autonomous road vehicle (ARV) development aims to address these complex environments, one area that is still new and open is ARV emergency obstacle avoidance at highway speeds (55-165 km/h) and on slippery road surfaces. When introducing obstacle avoidance capabilities into an ARV, it is important to target performance that meets or exceeds that of human drivers.This dissertation highlights subsystems within an entire ARV, which are crucial for the completion of a highly functional emergency obstacle avoidance maneuver (EOAM), and combines them in a novel framework while considering the nuances of traveling at highway speeds and/or slippery road surfaces. The primary subsystems developed and tested in this research include the synthesis of ARV sensing, perception, decision making, control, and actuation. These subsystems are introduced with some novelties to the current state-of-the-art as well as the holistic ARV EOAM Framework, designed to handle highway speeds and slippery surfaces, as a novelty. Lastly, a newly considered testing and validation methodology for ARV EOAM performance and validation is presented. This general obstacle avoidance capability assessment (GOACA) has implications for adoption by national or even global regulation bodies, regarding ARV EOAM safety performance while requiring all the core ARV systems to perform well, and in harmony, to achieve top marks

Cyber security is a major concern of computing systems. Different security controls are developed to mitigate or prevent cyber attacks. Such controls include cryptography, firewalls, intrusion detection systems, access controls, and strong authentication. These controls mainly protect the secure-system properties: confidentiality, integrity, and availability. The Antivirus software (AV) is considered the last line of defense against variety of security threats. The AV maintains a database of virus signatures against which it checks data. Had a match occurred, the AV would have reacted to the threat. Given the importance of the AV, different attacking techniques have been developed to evade the AV detection and render it useless. In this paper, we want to check how the AV behaves under pressure. We make the AV extremely busy in order to bypass its detection. We test several commercial AVs against three scenarios: when data flow from the hard drive (HD) into the main memory (reading), when data flow from the main memory into the HD (writing), and when data flow through the network (sending and receiving). This paper shows that when the AV is overloaded, some malwares can evade detection (in the reading scenario) and enjoy the existence for much more time on the HD (in the writing scenario). Finally, we show that the AVs (or at least the ones we tested in this paper) do not check network data as long as they are not written to or read from the HD. [ABSTRACT FROM AUTHOR]

- Abstract
Risk assessment instruments are widely used to predict risk of adverse outcomes, such as violence or victimization, and to allocate resources for managing these risks among individuals involved in criminal justice and forensic mental health services. For risk assessment instruments to reach their full potential, they must be implemented with fidelity. A lack of information on administration fidelity hinders transparency about the implementation quality, as well as the interpretation of negative or inconclusive findings from predictive validity studies. The present study focuses on adherence, a dimension of fidelity. Adherence denotes the extent to which the risk assessment is completed according to the instrument’s guidelines. We developed an adherence measure, tailored to the Short-Term Assessment of Risk and Treatability: Adolescent Version (START:AV), an evidence-based risk assessment instrument for adolescents. With the START:AV Adherence Rating Scale, we explored the degree to which 11 key features of the instrument were adhered to in 306 START:AVs forms, completed by 17 different evaluators in a Dutch residential youth care facility over a two-year period. Good to excellent interrater reliability was found for all adherence items. We identified differences in adherence scores on the various START:AV features, as well as significant improvement in adherence for those who attended a START:AV refresher workshop. Outcomes of risk assessment instruments potentially impact decision-making, for example, whether a youth’s secure placement should be extended. Therefore, we recommend fidelity monitoring to ensure the risk assessment practice was delivered as intended.
