Presentation for the AMI Conference 2022

One of the major challenges for researchers and governments across the world is reducing resources-waste or loss. Resources loss can happen if there is not a capable control system that contributes to environmental change. The specific aim is to create user-friendly control and monitoring system to reduce the waste in resources. New Artificial intelligence techniques have been introduced to play an important part in developing such systems.\ud In oilfields, the oil is extracted then distributed via oil pipes until it reaches the end consumer. This operation will occur without a full and complete monitoring for the oil in the pipeline’s journey to the provider. Although, the existing oilfield monitoring systems can communicate locally but they will not send information back to the main provider. That means the provider is not aware of the whole circumstances happened in the transportation process. That gives the provider no control on the process. For example, a sudden decision from the main provider to stop transporting to a specific destination or knowing where the leakage is and which pipe is leaking in the pipelines grid.\ud This paper, introduces for the first-time oilfield pipeline Neuro-fuzzy (NF) supervision system using Simscape simulation software package. This system can be the first step solution to keep real time communication between the main provider and the oil transportation process in the oilfields and enables the provider to have full supervision on the oil pipes grid. The simulation supervision system illustrates a clear real-time oilfield pipeline grid that gives the provider the ability to control and monitor pipeline grid and prioritise the recovering process. The two parameters selected for control and monitoring were volume and pressure. The results in this paper show full control for the NF supervision system on the transportation process.

Software agents are the delegated subcontractors essential to connect the end-user to the bank and payment providers in a distributed service offering. This paper evaluates the key role that the different software agent types play to facilitate collaboration between clients and banks to perform online transactions. It highlights the threats and imminent risks that these software agents introduce in the chain as well as how these threats affect the trust relationship between principals. The discussed threats and resulting risks suggest vulnerabilities in the current software agent model which are beyond the bank and end user's control. Both principals, the client and the service provider, are open to potential legal, security, quality of service, confidentiality and privacy compromises which influence the overarching trust relationship. There is resounding literature to illustrate advances that have been made to address the exposed challenges. However, a gap of misfortune remains where the software agent can act on its own accord exposing the contracting principals to internal and externally engineered threats thus tainting the trust relationship between these parties.

Co-morbidity of mental health and substance misuse problems (or "Dual Diagnosis") is highly prevalent in mental health and drug treatment services. The parallel approach, where the two conditions are treated at the same time in separate services, is the current accepted response to Dual Diagnosis. Joint working and continuity of care cannot be achieved without a consistent quality drug and alcohol assessment in mental health services. This editorial argues that that professional curiosity plays an important role in substance misuse assessment, especially when is carried out outside specialist drug and alcohol services.

Researchers have used extensive simulation and experimental studies to understand TCP performance in wireless multihop networks. In contrast, the objective of this paper is to theoretically analyze TCP performance in this environment. By examining the case of running one TCP session over a string topology, a system model for analyzing TCP performance in multihop wireless networks is proposed, which considers packet buffering, contention of nodes for access to the wireless channel, and spatial reuse of the wireless channel. Markov chain modelling is applied to analyze this system model. Analytical results show that when the number of hops that the TCP session crosses is fixed, the TCP throughput is independent of the TCP congestion window size. When the number of hops increases from one, the TCP throughput decreases first, and then stabilizes when the number of hops becomes large. The analysis is validated by comparing the numerical and simulation results

While online shopping are becoming more accepted by people in modern life, cardholders are more concerned about card fraud and the lack of cardholder authentication in the current online credit card payment. This paper proposes a purchase protocol with live cardholder authentication for online transactions which combines telephone banking and online banking together. The order information and payment information are sent though the Internet and encrypted by asymmetric key encryption. The cardholder is authenticated by the card issuing bank ringing back at the customer’s phone number and the cardholder inputting the secure PIN and the amount to pay. The multichannel authentication makes the cardholder feel secure and card fraud difficult. Furthermore, the protocol does not require the cardholder to obtain public key certificates or install additional software for online transactions.

Conventional entity authentication is not enough to build a secure pervasive computing environment. Being sure that you are talking to the expected entity does not guarantee it is going to do what you expect him to do, and only that. This paper introduces a concept of “trustworthy authentication” in pervasive computing which is defined as entity authentication accompanied by an assurance of trustworthy behaviour of the authenticated entity. It discusses how to provide trustworthy authentication in pervasive computing using the example of a roaming customer wishing to print his email on a public printer. A two-level hierarchical trustworthy authentication scheme is proposed where local and higher-level authorization servers issue trustworthiness certificates after receiving trustworthiness records from the printer, signed by its users. The proposed scheme may be generalized for trustworthy authentication of security devices such as firewalls.

Virtual Reality technology, especially visualization and auralization, provides a useful method to interactively implement the subjective analysis and evaluation of acoustic properties prior to the actual construction of a building. This paper presents a Virtual Environment-based walk-through system for interactive acoustic evaluation of buildings within a CAVE environment. It describes the architecture of the system, the system components, schedule algorithm, synchronous integration of acoustic simulation and visualization. The trade-off algorithm of the real time simplified acoustic space simulation by B-format soundfield representation, non real time detailed acoustic space simulation and the comparison between them are also mentioned. Some cases such as airport, cinema, boardroom, underground station and classroom are studied in the two simulation methods respectively. The potential applications of this system are presented as well.

A novel approach to implement the multiview autostereoscopic display system is presented. This implementation brings together a high frame rate digital micro-mirror device (DMD) projector, an active shutter, and an optical wedge. It facilitates the modulation of the DMD to achieve extra high frame rate with a trade-off in greyscale resolution. The results have the great potential for commercialising the autostereoscopic display system.

Presented at the British Psychological Society's annual conference for the Children, Young People and Families Division in October 2015, this presentation looks at how the Pyramid model of early intervention is implemented in schools across the UK. It discusses the benefits and the challenges in ensuring implementation fidelity when working in a diverse range of primary and secondary schools.

The sudden shift from traditional to e-learning education has encouraged researchers to evaluate and review the available active teaching and learning models to propose and create an active online teaching and learning methods. It is surprising to find that there is little research done on Electrical and Electronic Engineering students to evaluate their engagement with these methods. Therefore, this research covers strategies used with Electrical and Electronic Engineering foundation students to develop an active online teaching and learning. The research also addresses the learning support given through the pandemic period to keep students thoughtfully engaged and motivated while enabling a safe, non-judgmental environment where views and perspectives are encouraged. The teaching model used for Applied Engineering Project (AEP) module merged the problem-based learning model with the just-in-time teaching model (or flipped classroom). The problem-based learning model was the most appropriate learning model to deliver the APE module’s learning outcomes. Whereas the strategy of using the just-in-time teaching model shifted the focus of teaching from knowledge transmission to knowledge structuring by students and encourage the use of tasks. The teaching approach includes group discussion, teacher’s explanation, previous students’ exemplars , peer assessment and one-to-one sessions. The delivery was supported by the university e-learning platform (Blackboard Ultra, AppsAnywhere, etc.). Near the end of the module, a students’ questionnaire was taken. The results were constructive and promising as the students’ input will enable me to enhance the tools used for more active learning approaches. I have found the benefits of active T &L strategies in student learning in terms of student engagement, ownership of learning, and development of critical thinking and problem-solving skills easily outweigh the additional effort required, and are clearly relative to traditional, passive approaches to teaching.

As for many other disciplines, the abrupt move to online teaching a bit over a year ago forced us to rethink student engagement in our mathematics and statistics modules beyond the traditional whiteboard.\ud \ud Whilst challenging, this has also been a unique opportunity for us to test tools and ideas that have been available for some time but were, perhaps, not considered seriously pre Covid.\ud \ud In this presentation, I will discuss some practical tools and techniques that have been used over the past year to engage our students in the online learning environment. This includes the use of different types of quizzes, tablets, and online forums.\ud \ud In addition to reporting on my own experience of advantages, disadvantages, scopes, and limitations, I will make some suggestions for future developments. In particular, I will be contemplating how the past year’s experiences can be used to enhance student engagement in mathematics and statistics learning once we return to face-to-face teaching.

The changes in the mean-square charge radius (relative to 209Bi), magnetic dipole, and electric quadrupole moments of 187,188,189,191Bi were measured using the in-source resonance-ionization spectroscopy technique at ISOLDE (CERN). A large staggering in radii was found in 187,188,189Big, manifested by a sharp radius increase for the ground state of 188Bi relative to the neighboring 187,189Big. A large isomer shift was also observed for 188Bim. Both effects happen at the same neutron number, N=105, where the shape staggering and a similar isomer shift were observed in the mercury isotopes. Experimental results are reproduced by mean-field calculations where the ground or isomeric states were identified by the blocked quasiparticle configuration compatible with the observed spin, parity, and magnetic moment. ispartof: Physical Review Letters vol:127 issue:9 ispartof: location:United States status: published

Part 2: User Experiences and Wellbeing at Work (UX@Work); International audience; To improve human performance, interactive technologies are going towards more automated systems that involve computers, robots and cyber-physical systems into the decision-making process. While automation can lead to increased performance and reduced impact of human errors, interactive technologies without optimal design can have a negative impact on the experience of operators and end-users, leading to suboptimal performance of the automated systems. In this research, we aim to evaluate and refine Human Work Interaction Design (HWID) framework to be applicable in various highly-automated settings including Industry 4.0 environments. This will be performed via a thorough literature review as the first step. The list of identified factors playing a potential role in various interactive systems will then be evaluated and optimised in three case studies. We will try to understand how to maximise collaborations between the users and the machine in interactive systems. A practical approach for evaluating both employees’ and end-users’ perspectives in three scenarios with different levels of automation will be assessed. We will evaluate the outputs in multiple levels of organisations, employees and end-users. The ultimate output of the study will be a framework or model that will help in designing future research studies for various automation scenarios, especially semi-autonomous systems that involve high levels of interaction between users and the machine. We will provide guidelines for implementation of the proposed framework in different scenarios. We expect that the framework output of this research will provide a comprehensive guideline applicable to many Industry 4.0 technologies.

Increased cockpit automation on modern jet aircraft aim to reduce the risk of Undesired Aircraft State (UAS) instances such as Loss of Control in Flight (LOC-I). Although LOCI globally accounts for only 9% of all analysed accidents IATA has reported that it was responsible for 58% of all accident fatalities in 2017. The focus of this paper is to answer whether Threat and Error Management and Crew Resources Management (CRM) techniques are an efficient risk management tool when facing a LOC-I threat. Three LOCI final aircraft accident reports were analysed to understand the structure of Human Factors (HF) during these flights. Methods from the HF field such as the Generic Error Modelling System (GEMS) and Skill-, Rule- and Knowledge-based (SRK) error approach provided invaluable insights to identify potential findings. A holistic investigation of cognitive structures in flight path management helped to visualise latent conditions and cognitively demanding tasks during LOC-I in routine operations. Bearing in mind the limited number of cases considered in this paper it should be considered as an overview in LOC-I accident analysis. It shows that leadership and teamwork, as essential aspects of CRM training, can serve as key strategies to mitigate HF problems and LOC-I risks.

International audience; Caribbean communities were mobile long before European colonization and their modes of production and culture were evolving by frequent exchanges among the Caribbean islanders and the Northern coast of South America. However, the region has not fully benefited by the advent of the five Technological Revolutions since 1771. Moreover, in the last two decades of the XX century, the Caribbean Small Islands Developing States (SIDS) were severely affected by the migration of their tertiary educated population towards the developed world, a trend that continues today.Bibliometric approaches have been used to identify not only the brain drain, but also how the contemporary knowledge is created through the international network of scientific collaboration. In this study we use the Scopus bibliographic database to analyse the scientific output and international collaboration of the 13 Caribbean SIDS in the period between 2000 and 2018. The main scientific collaborator of the region as a country is United States, except for Cuba, which is Spain. Consequently, North America, Europe and the Caribbean islands share the higher proportion of co-authoring articles. In terms of institutional representation, the University of West Indies has, in aggregate, the highest output with 11,497 documents from 11 out of 13 SIDS. The main contributor as a country is Jamaica (5018), followed by Trinidad and Tobago. A group of high output academic institutions are University of Havana (4979), followed by Universidad Central de Las Villas, Institute of Tropical Medicine Pedro Kouri and the Centre of Genetic Engineering and Biotechnology, all of them in Cuba and with no significant collaboration with the rest of the region.In previous bibliometric studies we found that the scientists working abroad has the potential to become agents for development of the home country and region, diversifying the scientific collaboration.

Part 11: Panels; International audience; The aim of this panel is to raise awareness and to foster discussions around the notions of Automation and User Experience and their interplay in the design, development, evaluation and deployment of interactive systems. User Experience is taken in its broad meaning as defined in the white paper of https://www.allaboutux.org/ [11]. As for automation we consider here its wide perspective as proposed in [4] – The Seven Deadly Myths of “Autonomous Systems”. In a time where there is strong push towards more and more automation in our daily life, the panel will question the impact of such trend on users’ experiences in multiple contexts such as work, entertainment, learning, as well as question other important emerging issues such as ethics, engagement and automation rationale.

Part 12: Workshops; International audience; As digitalization pervades diverse types of workplaces, an increasing part of employees’ work is with interactive technologies. Therefore, user experience of the technologies at work has an important influence to the job satisfaction, work motivation, and employee wellbeing. However, previous research on these topics rarely considers the digitalized work processes and the tools used at work. This workshop invites experts studying work with digital technologies to discuss the impact of these kind of tools on employee wellbeing. The UX@Work workshop aims to build a research agenda for tackling a multitude of overlooked research topics in this area.

Part 1: Organisational Semiotics: Theory and Application; International audience; Patient safety and accidental harm or iatrogenic errors are increasingly important healthcare issues resulting in high costs and mortality. The way clinical workflow and actions are communicated can impact patient safety. Although much work has been done to identify the individual human factors and recommendations are made to control and reduce human factor errors, little work has been done to provide a structured methodology to analyse and control human factor influencing patient safety outcomes. In this paper, we build on the previous work on automatic development of clinical pathways, semiotic approach to modelling norm-base clinical pathways and propose a Human Factor Failure Modes and Effects Analysis (HFMA) which offers a systematic approach to define, design and incorporation of human factors into formal design of clinical pathways. Organisational semiotics methods specifically NAM and SAM are applied to identify and analyse controls to reduce the adverse impact of human factors in healthcare settings. This is achieved through modelling and integration of human factors into clinical pathways. This will result in more rigorous control the care process ensuring completeness, consistency and patient safety by enabling the mapping of formal and informal/safety controls into clinical pathways.

Part 1: Organisational Semiotics: Theory and Application; International audience; Abduction is a logical reasoning process that allows the discovery and creation of new knowledge. However, the function of knowledge is not explicitly developed in the existing research on abduction. Developing information architecture is a scientific inquiry in a practical context as it engages multiple stakeholders. However, the current research in information architecture does not appear to be underpinned by sound theoretical foundations. This paper proposes a norm-based abduction process (NAP) where norms are seen as knowledge in developing information architecture. A case study of a UK hospital is used for illustration purposes. The key contribution of this paper is to incorporate norms in the existing abduction process, to assert abduction as the foundation of a logical reasoning process and to derive a theoretical proposition for information architecture.

This paper presents a method for externalising and formalising knowledge involving the selection of hydrometallurgical process flowsheets for gold extraction from ores. A case-based reasoning (CBR) system was built using an open source software myCBR 3.0. The aim of the systems is to recommend flowsheet alternatives for processing a potential gold ore deposit. Nine attributes: Ore type, Gold ore grade, Gold distribution, Gold grain size, Sulfide present, Arsenic sulfide, Copper sulfide, Iron sulfide and Clay present were modelled and several literature sources of actual gold mines and processes were used for acquiring cases for the system. After preliminary testing, functional evaluation of the built CBR system was carried out by using five real mining projects as test cases. Additionally, human experts in the field of gold hydrometallurgy were interviewed to demonstrate the benefits of the CBR system as it holds no human biases towards any processing techniques. It was found that the suggestions of the CBR system provided useful information and direction for further process design and performed well compared to the interviewed human experts, thus confirming that the system is of practical relevance to the process engineer designing an industrial gold processing plant. The current model was found to be a functioning basis for further development through additional attributes, adjusted attribute weighting and increased number of cases.

“Facecook”, design and rool-out of a community based social network to promote healthy eating practices amongst low income population”. 2nd Cook and Health Symposium

International audience; Introduction and objectives: Frequent consumption of commercially-prepared meals appears to be associated with obesity. Such a relationship could also be observed between home cooking practices and obesity but it has not been documented so far. We investigated the prospective association between food preparation behaviours and 5-year weight gain and the onset of obesity after 5 years in adults. Method: We prospectively examine 5-year weight gain and the risk of obesity after 5 years in 3,629 men and 9,221 women aged ≥ 18 years participating in the NutriNet-Santé cohort study. Self-reported weight, height and cooking practices were collected at baseline and 5 years later. Food preparation behaviours were assessed at baseline using a web-based questionnaire. Cooking skills, preparation from scratch, i.e. use of raw or fresh ingredients that had no or minimal processing and kitchen equipment were assessed using a 0-10-point score and, frequency of meal preparation, enjoyment of cooking and willingness to cook better or more frequently were categorical variables. Associations between various dimensions of food preparation behaviours and 5 years weight gain and risk to be obese 5 years later were respectively assessed using analysis of covariance and logistic regression models stratified by sex and adjusted for age, household composition and socio-economic factors. Results: In both genders, associations of frequency of meal preparation, enjoyment of cooking and willingness to cook better or more frequently, cooking skills and kitchen equipment with 5-year weight gain or obesity risk were not statistically significant (P>0.05). In women, score of preparation from scratch was inversely associated with risk to be obese five years later (OR=0.92 (0.86; 0.98), P=0.03) and women with low score of preparation from scratch more gained weight over 5 years (mean weight gain=1.69 (0.14)) compared with those with the highest score (mean weigh gain=0.87 (0.11), P=0.04). Conclusion: Use of raw or fresh ingredients that had no or minimal processing was related to lower risks of obesity and weight gain in women. Such complex relationships should be taken into account to effectively target public health efforts in obesity prevention.

Part 10: Workshops; International audience; Over the last decade, empirical relationships between work domain analysis and HCI design have been identified by much research in the field ofHuman Work Interaction Design (HWID) across five continents. Since this workshop takes place at the Interact Conference in Mumbai, there is a unique opportunity to observe technology-mediated innovative work practices in informal settings that may be related to the notion of International Development. In this unique context, this workshop proposes to analyze findings related to opportunities for design research in this type of work domains: a) human-centered design approaches for specific work domains (workplaces, smart workplaces); b) visions of new roles for workplaces that enhance both work practice and interaction design. In order to do this, participants engage with field trips, gather data and discuss their experience at the workshop on the following day.

Background: The specific role of major socio-economic indicators in influencing food preparation behaviours could reveal distinct socio-economic patterns, thus enabling mechanisms to be understood that contribute to social inequalities in health. This study investigated whether there was an independent association of each socio-economic indicator (education, occupation, income) with food preparation behaviours. Methods: A total of 62,373 adults participating in the web-based NutriNet-Santé cohort study were included in our cross-sectional analyses. Cooking skills, preparation from scratch and kitchen equipment were assessed using a 0-10-point score; frequency of meal preparation, enjoyment of cooking and willingness to cook better/more frequently were categorical variables. Independent associations between socio-economic factors (education, income and occupation) and food preparation behaviours were assessed using analysis of covariance and logistic regression models stratified by sex. The models simultaneously included the three socio-economic indicators, adjusting for age, household composition and whether or not they were the main cook in the household. Results: Participants with the lowest education, the lowest income group and female manual and office workers spent more time preparing food daily than participants with the highest education, those with the highest income and managerial staff (P < 0.0001). The lowest educated individuals were more likely to be non-cooks than those with the highest education level (Women: OR = 3.36 (1.69;6.69); Men: OR = 1.83 (1.07;3.16)) while female manual and office workers and the never-employed were less likely to be non-cooks (OR = 0.52 (0.28;0.97); OR = 0.30 (0.11;0.77)). Female manual and office workers had lower scores of preparation from scratch and were less likely to want to cook more frequently than managerial staff (P < 0.001 and P < 0.001). Women belonging to the lowest income group had a lower score of kitchen equipment (P < 0.0001) and were less likely to enjoy cooking meal daily (OR = 0.68 (0.45;0.86)) than those with the highest income. Conclusion: Lowest socio-economic groups, particularly women, spend more time preparing food than high socioeconomic groups. However, female manual and office workers used less raw or fresh ingredients to prepare meals than managerial staff. In the unfavourable context in France with reduced time spent preparing meals over last decades, our findings showed socioeconomic disparities in food preparation behaviours in women, whereas few differences were observed in men., SCOPUS: ar.j, info:eu-repo/semantics/published

Part 5: Trends, Challenges and New Issues in Education, Health and eScience Systems; International audience; While Co-Design approaches have been used in designing technology enhanced learning (TEL) by different scholars, research is needed to understand the relationships between technologies, design and practice. This paper presents organisational semiotics (OS) as an approach for Co-Design of Technology Enhanced Learning. This perspective will provide an insight into the Co-Design of technology and learning in higher education.

International audience; This one-day workshop aims to contribute to the goals of the IFIP 13.6 Human Work Interaction Design (HWID) working group, i.e., to establish relationships between empirical work-domain studies and recent developments in interaction design. This goal translates to the workshop by focusing on work environments that are challenging for research and design; from physically or spatially unusual workplaces (e.g., oil platforms), mentally demanding or specifically boring work (e.g., control rooms, academics) to challenging social situations at work (e.g., in hospitals). The workshop aims to discuss resulting constraints for research and design, e.g., restricted access for research, or difficulties in articulating the specifics of the workplaces to a wider audience that is not familiar with them. Some work environments may even impede forms of design research, e.g., critical or provocative design will be hard to carry out in safety- or efficiency-critical workplaces. Thus, ways to generate knowledge addressing the design of interactive artifacts for challenging workplaces will be discussed.

The Weddell Sea sector is one of the main formation sites for Antarctic Bottom Water and an outlet for about one fifth of Antarctica’s continental ice volume. Over the last few decades, studies on glacialegeological records in this sector have provided conflicting reconstructions of changes in ice-sheet extent and ice-sheet thickness since the Last Glacial Maximum (LGM at ca 23e19 calibrated kiloyears before present, cal ka BP). Terrestrial geomorphological records and exposure ages obtained from rocks in the hinterland of the Weddell Sea, ice-sheet thickness constraints from ice cores and some radiocarbon dates on offshore sediments were interpreted to indicate no significant ice thickening and locally restricted grounding-line advance at the LGM. Other marine geological and geophysical studies concluded that subglacial bedforms mapped on theWeddell Sea continental shelf, subglacial deposits and sediments over-compacted by overriding ice recovered in cores, and the few available radiocarbon ages from marine sediments are consistent with major ice-sheet advance at the LGM. Reflecting the geological interpretations, different icesheet models have reconstructed conflicting LGM ice-sheet configurations for the Weddell Sea sector. Consequently, the estimated contributions of ice-sheet build-up in the Weddell Sea sector to the LGM sealevel low-stand of w130 m vary considerably. In this paper, we summarise and review the geological records of past ice-sheet margins and past icesheet elevations in the Weddell Sea sector. We compile marine and terrestrial chronological data constraining former ice-sheet size, thereby highlighting different levels of certainty, and present two alternative scenarios of the LGM ice-sheet configuration, including time-slice reconstructions for post- LGM grounding-line retreat. Moreover, we discuss consistencies and possible reasons for inconsistencies between the various reconstructions and propose objectives for future research. The aim of our study is to provide two alternative interpretations of glacialegeological datasets on Antarctic Ice- Sheet History for the Weddell Sea sector, which can be utilised to test and improve numerical icesheet models

Part 1: Long and Short Papers; International audience; This one-day workshop aims to present different local and indigenous perspectives from all over the world in order to lead into an international dialogue on re-framing concepts and models in HCI/Interaction Design. The target audience is HCI researchers and practitioners who have experience with working with culture and HCI. The expected outcome of the workshop is a) network building among the participants, b) a shortlist of papers that can be basis for a proposal for a special issue of the UAIS journal, and c) identify opportunities to develop a funded network or research proposal.

Part 1: Organisational Semiotics: Theory and Application; International audience; The growth of mobile technologies and smartphones is reshaping the individual and organisational behaviour which affect the business environment. One of the key challenges of mobile payment is how to understand and manage user expectations and technology acceptance. Therefore, to better understand mobile payment use and acceptance, we need to analyse the factors and barriers that influence technology use. The investigation uses Technology Acceptance Model in conjunction with Organisational Semiotics, a socio-technical method of design, to overcome possible limitations addressed in research. This approach offers methods that can help to develop a research model for mobile payment use focusing on technical and social aspects.
