This paper presents SnappView, an open-source software development kit that facilitates end-user review of graphical user interfaces for mobile applications and streamlines their input into a continuous design life cycle. SnappView structures this user interface review process into four cumulative stages: (1) a developer creates a mobile application project with user interface code instrumented by only a few instructions governing SnappView and deploys the resulting application on an application store; (2) any tester, such as an end-user, a designer, a reviewer, while interacting with the instrumented user interface, shakes the mobile device to freeze and capture its screen and to provide insightful multimodal feedback such as textual comments, critics, suggestions, drawings by stroke gestures, voice or video records, with a level of importance; (3) the screenshot is captured with the application, browser, and status data and sent with the feedback to SnappView server; and (4) a designer then reviews collected and aggregated feedback data and passes them to the developer to address raised usability problems. Another cycle then initiates an iterative design. This paper presents the motivations and process for performing mobile application review based on SnappView. Based on this process, we deployed on the AppStore "WeTwo", a real-world mobile application to find various personal activities over a one-month period with 420 active users. This application served for a user experience evaluation conducted with N1=14 developers to reveal the advantages and shortcomings of the toolkit from a development point of view. The same application was also used in a usability evaluation conducted with N2=22 participants to reveal the advantages and shortcomings from an end-user viewpoint.

Severe process variations in advanced technology require more devices under test (DUTs) to be characterized in the wafer acceptance test (WAT) to more reliably qualify the fabricated wafers. However, conventional WAT takes a long test time to acquire sufficient characterization data. This article proposes an on-wafer test circuity to fast and accurately characterize DUT arrays during a single probing. It integrates the proposed compact DUT cells, an IR drop compensator, and a wide-input-range (WIR) current digitizer. The proposed IR drop compensator collaborates with the DUT cells to address the IR drop issue and thus improve the test accuracy of the parameter tests. The proposed multi-mode 12-bit WIR current digitizer achieves a 140-dB input range for digitizing the DUTs' output currents in various WAT test items. It eliminates the need of high-end ATE and saves the test cost. A prototype IC including 2048 DUTs has been designed and fabricated in 90-nm CMOS. Its active area is only 60 μm by 1900 μm which can be placed in a scribe line as conventional WAT structure is. Experimental results demonstrate the proposed test circuitry can render spatial variation results and other device parameters of the DUT arrays in addition to typical WAT items.

Novel technologies, such as smartphones or virtual reality, are seen as attractive tools with high potential to trigger behavioral change. Therefore, they are embraced enthusiastically by both business and academia. Interventions using technology as tools can be expected to further increase their popularity in the near future. A large amount of contemporary research seems to focus on examining user experience and technology acceptance. Such a focus is a natural first step in understanding a novel technology. At the same time, much less is known about the actual effectiveness of novel technologies in interventions. This limited knowledge represents a potential challenge to researchers when deciding which particular technology example to choose for their work. This theoretical study proposes an informed approach to making that choice, particularly for road safety interventions. The approach is grounded in the Theory of Planned Behaviour. Criteria are suggested for initial technology impact evaluation, which should help researchers and practitioners compare different technology examples. Further criteria are touched upon in relation to practicalities around using technologies in interventions. The proposed framework may help future research of technology effectiveness by saving stakeholders' time to decide which technology they should adopt and test.

Emergency signage conveys exit route information enabling occupants to identify and utilise emergency exits during evacuation. However, it has been frequently demonstrated that static signs are insufficient to attract people's attention. Previous incidents also demonstrate that if exit routes and exits become compromised by the incident, static signs are unable to adapt as required. A goal of the signage industry is to address these limitations while maintaining the clear and unambiguous information conveyed. A signage concept addressing these limitations incorporating a pair of linked adjacent signs, a standard EXIT sign and a text-based ‘NO-EXIT’ sign, is proposed. At any one time, only one sign is activated, displaying either EXIT or NO-EXIT. The active sign can also flash to improve detectability. To assess whether this concept was acceptable, an online international survey, based on the ANSI Z535.3 comprehension test methodology was conducted. The results demonstrate that this novel concept fails to meet the acceptance criteria for safety signs, and as a result, the concept was abandoned by the manufacturer. This study also highlights the importance of conducting comprehension tests for any new safety signage design and the need for composing guidelines for design and application of dynamic signs.

Purpose To develop and implement an acceptance procedure for the new Elekta Unity 1.5 T MRI‐linac. Methods Tests were adopted and, where necessary adapted, from AAPM TG106 and TG142, IEC 60976 and NCS 9 and NCS 22 guidelines. Adaptations were necessary because of the atypical maximum field size (57.4 × 22 cm), FFF beam, the non‐rotating collimator, the absence of a light field, the presence of the 1.5 T magnetic field, restricted access to equipment within the bore, fixed vertical and lateral table position, and the need for MR image to MV treatment alignment. The performance specifications were set for stereotactic body radiotherapy (SBRT). Results The new procedure was performed similarly to that of a conventional kilovoltage x‐ray (kV) image guided radiation therapy (IGRT) linac. Results were acquired for the first Unity system. Conclusions A comprehensive set of tests was developed, described and implemented for the MRI‐linac. The MRI‐linac met safety requirements for patients and operators. The system delivered radiation very accurately with, for example a gantry rotation locus of isocenter of radius 0.38 mm and an average MLC absolute positional error of 0.29 mm, consistent with use for SBRT. Specifications for clinical introduction were met.

Acceptance sampling is an important technique in quality assurance; its main goal is to achieve the most accurate decision in accepting lot using minimum resources. In practice, this often translates into minimizing the required sample sizes for the inspection, while satisfying the maximum allowable risks by consumer and producer. Numerous sampling plans have been developed over the past decades, the most recent being the incorporation of grouping to enable simultaneous inspection in the two-sided chain sampling which considers information from preceding and succeeding samples. This combination offers improved decision accuracy with reduced inspection resources. To-date, two-sided group chain sampling plan (TSGCh) for characteristic based on truncated lifetime has only been explored for Pareto distribution of the 2nd kind. This article introduces TSGCh sampling plan for products with lifetime that follows generalized exponential distribution. It focuses on minimizing consumer's risk and operates with three acceptance criteria. The equations that derived from the set conditions involving generalized exponential and binomial distributions are mathematically solved to develop this sampling plan. Its performance is measured on the probability of lot acceptance and number of minimum groups. A comparison with the established new two-sided group chain (NTSGCh) indicates that the proposed TSGCh sampling plan performs better in terms of sample size requirement and consumers' protection. Thus, this new acceptance sampling plan can reduce the inspection time, resources, and costs via smaller sample size (number of groups), while providing the desired consumers' protection.

Background: Test-Driven Development (TDD) is an iterative software development process characterized by test-code-refactor cycle. TDD recommends that developers work on small and manageable tasks at each iteration. However, the ability to break tasks into small work items effectively is a learned skill that improves with experience. In experimental studies of TDD, the granularity of task descriptions is an overlooked factor. In particular, providing a more granular task description in terms of a set of sub-tasks versus providing a coarser-grained, generic description. Objective: We aim to investigate the impact of task description granularity on the outcome of TDD, as implemented by novice developers, with respect to software quality, as measured by functional correctness and functional completeness. Method: We conducted a one-factor crossover experiment with 48 graduate students in an academic environment. Each participant applied TDD and implemented two tasks, where one of the tasks was presented using a more granular task description. Resulting artifacts were evaluated with acceptance tests to assess functional correctness and functional completeness. Linear mixed-effects models (LMM) were used for analysis. Results: Software quality improved significantly when participants applied TDD using more granular task descriptions. The effect of task description granularity is statistically significant and had a medium to large effect size. Moreover, the task was found to be a significant predictor of software quality which is an interesting result (because two tasks used in the experiment were considered to be of similar complexity). Conclusion: For novice TDD practitioners, the outcome of TDD is highly coupled with the ability to break down the task into smaller parts. For researchers, task selection and task description granularity requires more attention in the design of TDD experiments. Task description granularity should be taken into account in secondary studies. Further comparative studies are needed to investigate whether task descriptions affect other development processes similarly.

The success of JISKa is inseparable from the role of reviewers and authors. Unfortunately, JISKa had never been assessed or evaluated by reviewers and authors despite the fact that assessment from the reviewers and authors would be valuable feedback for JISKa’s self-evaluation. Therefore, survey-based research has recently been conducted to assess JISKa’s performance using the User Acceptance Test of OJS version 2.4.8.0. This study used a survey method to obtain an assessment and evaluation from reviewers and authors related to JISKa.The respondents in this study consist of 68 authors and 26 reviewers. The result of this study stated that 91.2% of the authors and 84.6% of reviewers are satisfied with JISKa. A percentage number of 100% of writers and reviewers wants JISKa to raise its level of Sinta accreditation. This accreditation is awarded in 2018 and will end in 2023. JISKa is now on Sinta 4.The JISKa website appearance looks good and easy to use. The dashboard on the JISKa page is user-friendly for the author. However, the current version of JISKa OJS 2.4.8.0 needs to be upgraded to OJS version 3. There are some points for the future consideration of JISKa: JISKa needs to promote itself more, upgrade the OJS version, and provide the reviewers with certificates of appreciation for future consideration.

The study of the economics of product testing was carried out on the example of three plastics processing industries - heat shrinkable films, pressure pipes and injection molded products for household needs. Methods for calculating the annual number of acceptance and periodic tests, as well as costing of various test methods, have been developed. The results of the study can be used to solve problems related to the development of the testing laboratory of the enterprise, as well as to directly attribute the testing costs to the cost of production..

The main focus of the recommended spatial accuracy tests for the multi‐leaf collimators (MLC) is calibration of the leaf position along the movement direction and overall alignment to the radiation isocenter. No explicit attention was typically paid to the alignment of the leaves from the opposing banks in the direction orthogonal to movement. This paper is a case study demonstrating that verification of such alignment at the time of acceptance testing is prudent. The original standard MLC (SMLC) on an MRIdian MRI‐guided linac (ViewRay Inc., Mountain View, CA, USA) was upgraded to a high‐speed MLC (HSMLC), which is supposed to be mechanically identical to the SMLC except for the higher drive screw pitch. The results of the end‐to‐end IMRT tests demonstrated unacceptable dosimetric results exemplified by an average and maximum ion chamber (IC) point dose error in the high‐dose low‐gradient region of 2.5 ± 1.4% and 4.6%, respectively. Before the upgrade, those values were 0.3 ± 0.7% and 0.9%, respectively. An exhaustive analysis of possible failure modes eventually zeroed in on the average misalignment of about 1 mm in the Y (along the couch) direction between the right and left upper MLC banks. The MLC was replaced, reducing the Y‐direction misalignment to 0.4 mm. As a result, the average and maximum IC dose‐errors became acceptable 1.0 ± 0.7% and 1.6%, respectively. Simple film and/or chamber array tests during acceptance testing can easily detect Y‐direction misalignments between opposing leaves banks measuring a fraction of a mm at isocenter. Left undetected, such misalignment can cause nontrivial dosimetric consequences.

Wafer test is carried out after integrated circuits (IC) fabrication to screen out bad dies. In addition, the results can be used to identify problems in the fabrication process and improve manufacturing yield. However, the wafer test itself may induce defects to otherwise good dies. Test-induced defects not only hurt overall manufacturing yield but also create problems for yield learning, so the source problems in testing should be identified quickly. In the wafer acceptance test process, dies are probed in a predetermined order, so test-induced defects, also known as site-dependent faults, exhibit specific patterns that can be effectively captured in test paths. In this paper, we analyze characteristics of test-induced defect patterns and define features that can be used by machine learning algorithms for the automatic detection of test-induced defects. Therefore, defective dies caused by the wafer test can be retested for yield improvement. Test data from six real products are used to validate the proposed method. Several machine learning algorithms have been applied, and experimental results show that our method is effective to distinguish between test-induced and fabrication-induced defects. On average, the prediction accuracy is higher than 97%.

The established group chain acceptance sampling plans (GChSP-1) functions with five acceptance criteria, while the modified group of chain acceptance sampling plans (MGChSP-1) operates with three acceptance criteria. Since the acceptance criteria affect the performances of the sampling plans, therefore, this article suggests a balanced approach by introducing a new group of chain acceptance sampling plans (NGChSP-1), where it functions with four acceptance criteria. The NGChSP-1 is developed by using minimum angle method which caters for producer’s and consumer’s risks. The generalized exponential distribution is selected as the lifetime distribution and the simulation for the NGChSP-1 is conducted at various values of design parameters using the Scilab programming. The finding shows that the optimal number of groups and the corresponding smallest theta for NGChSP-1 are smaller compared to those for the GChSP-1. For illustration purposes, the NGChSP-1 is then applied to real data of air conditioning equipment.

To date, in the mass production of medicines both in pharmaceutical companies and in pharmacies, more and more attention is paid to the practice of process validation. Validation is a key condition for the implementation of Good Manufacturing (GMP) and Pharmacy (GPP) practices, the standards of which are mandatory for medicines worldwide and in Ukraine. The aim of the work – validation of the technological process of preparation extemporaneous hymoding cream with hyaluronic acid in order to obtain documentary evidence of effective reproduction of the preparation of this medicine.

Материалы статьи посвящены актуальной теме – повышению качества посева семян зерновых культур. В ней отмечено, что известные конструкции лаповых и дисковых сошников имеют значительные тяговое сопротивление, образуют широкую борозду, которую затруднительно заделать, не обеспечивают качественное копирование рельефа поля. Всё это негативно сказывается на равномерности распределения семян зерновых культур, как по длине рядка, так и по глубине заделки. Наиболее перспективным направлением повышения качественных показателей работы посевного агрегата, является оснащение зерновых сеялок комбинированными сошниками. В статье приведено краткое описание и результаты приемочных испытаний зерновой сеялки С-7,2ПМ4 с новыми комбинированными однодисковыми сошниками, разработанными ФГБОУ ВО Пензенский ГАУ совместно с АО «Радиозавод» г. Пенза. Приемочные испытания проводились ФГБУ «Поволжская государственная зональная машиноиспытательная станция» (г. Кинель Самарской обл.) на полях ООО АПК «Комсомолец» Кинельского района Самарской области в соответствии с ГОСТ 31345-2017 «Техника сельскохозяйственная. Сеялки тракторные. Методы испытаний» [1-6]. При этом была проведена агротехническая, энергетическая, эксплуатационно – технологическая и экономическая оценка сеялки. В ходе приемочных испытаний было установлено, что комбинированные однодисковые сошники с копирующими колесами и сеялка С-7,2ПМ4 в целом надежно выполняет технологический процесс.

The article is devoted to the current issue – improving the quality of planting seeds of grain crops. It is noted that the major designs of shovel and disc coulters have significant traction resistance, form a wide furrow, which is difficult to close, and do not provide high-quality following of the field relief. All this negatively affects the uniformity of the distribution of grain seeds, both along the length of the row and the depth of placement. The most promising direction for improving the quality indicators of the sowing unit is to equip grain planters with combined coulters. The article presents a brief description and results of acceptance tests of the S-7,2PM4 (С-7,2ПМ4) grain planter with new combined single-disc coulters developed by the Penza State Agrarian University in cooperation with JSC (AO) "Radiozavod", Penza. Acceptance tests were conducted by the Federal State Budgetary Institution "Volga MIS" (Kinel, Samara Oblast) in the fields of LLC Agro-Industrial Complex "Komsomolets" Kinelsky district of the Samara Oblast in accordance with GOST 31345-2017 "Agricultural machinery. Tractor seeders. Test methods" [1-6]. At the same time, an agrotechnical, energetic, operational, technological and economic assessment of the seeder was carried out. During acceptance tests, it was found that the combined single-disc coulters with gauge-wheels and the S-7,2PM4 (С-7,2ПМ4) seeder reliably perform the technological process. At the working speed of the unit - 7.5-10.0 km/h, the number of seeds covered at a given depth was 87.2-89.2 %, the traction resistance was within 9.45-9.47 kN. It corresponds to tractors of the traction class 1.4. Labour costs were 0.27 work h/ha, while the total cost of money at the price of the seeder - 1241.67 rubles, amounted to 885.69 rubles/ha.

This paper describes the development of two experimental school library information systems for Malaysian schools. The results of a user study, conducted using different sets of questionnaire for both types of schools indicated that students in general, borrowed books from the library by browsing the shelves. Students seldom used the catalogue card for searching and only a small percentage reported that they were able to find the books successfully using the catalogue card. Based on the findings, a conceptual model of the prototype automated catalogue was developed - Virtual Library for use in primary schools, and ELIS for secondary schools. Both systems are divided into two main modules, the Administrator and the User module. User acceptance test showed that the majority of students found the systems user friendly. Students were also successful in the search tasks given. A high majority described the graphical user interface to be attractive and simple. This indicates the feasibility of using the systems for school libraries in Malaysia.

The trend of information system development and technological developments is continuously increasing. Every person or business actor must continuously update the technology. Based on the published results of a survey conducted by Indonesian Internet Service Providers Association at the end of 2018, internet users in Indonesia reached 171.17 million from 264.16 million people or 64.8% of the total population.. Related to this, the researchers conducted research on the implementation of e-commerce in Small and Medium Enterprise. Testing of this study uses the User Acceptance Test. The method that the authors do is by making a system that is applied to Small and Medium Enterprise.
