Background: Time series is a sequence of measurements made at regular time intervals. Tremendous work has been done on pipe break investigation and maintenance, using different models. However, the authors have not found any research work on pipe failures in water distribution networks using time series. Objective: The principal objective of this paper was to investigate the applications of time series analysis in modeling man-made (pipe breaks) and natural (rainfall) environmental systems. Methods: This objective was satisfied by employing the Time-Domain (Box-Jenkins) approach to assess two case studies in Kuwait of a water distribution network (pipe failures), and from rainfall rates measurement of a solid waste disposal site, respectively. The statistical analysis of these data was conducted with the aid of the BMDP and SAS computer software packages and by the use of the P2T programming procedure for the Box-Jenkins method. Results: The results showed a significant correlation between the data and the time series models provides good estimates of pipe reliability and rainfall measurements. Conclusion: Based on the significant results, time series analyses could and should be useful by water authorities in planning pipe maintenance and inspection. Moreover, it is recommended and it would be very useful to conduct similar studies on pipes carrying other fluids such as gas, air and oil.

Full textAbstract:
Modularity — the decoupling of software units — is essential for composition of real software systems from ready-made components. But for a long time one lacked a formal theory of modularity. Recently we have been developing Linear Software Models as rigorous theoretical modularity standards based upon plain Linear Algebra. By these models, decoupling means just linear independence, within a modularity matrix. This paper applies Linear Software Models to software systems, obtaining three consequences: (1) besides decoupling, various informal notions of software engineering, such as software modules, cohesion, and single responsibility, have for the first time a well-defined formal counterpart; (2) canonical building blocks like Software Design Patterns strictly obey the Linear Software Models; (3) larger software systems obey bordered Linear Models, allowing precise location and visualization of residual coupling. The latter consequences are demonstrated by case studies of software systems from the literature. The applicability of the Linear Software Models is quantitatively shown to scale well with system size, for the given case studies.

Full textAbstract:
<abstract><p>The optimization of fractional-order (FO) chaotic systems is challenging when simulating a considerable number of cases for long times, where the primary problem is verifying if the given parameter values will generate chaotic behavior. In this manner, we introduce a methodology for detecting chaotic behavior in FO systems through the analysis of Poincaré maps. The optimization process is performed applying differential evolution (DE) and accelerated particle swarm optimization (APSO) algorithms for maximizing the Kaplan-Yorke dimension ($ D_{KY} $) of two case studies: a 3D and a 4D FO chaotic systems with hidden attractors. These FO chaotic systems are solved applying the Grünwald-Letnikov method, and the Numba just-in-time (jit) compiler is used to improve the optimization process's time execution in Python programming language. The optimization results show that the proposed method efficiently optimizes FO chaotic systems with hidden attractors while saving execution time.</p></abstract>

Purpose – The purpose of this paper is to describe the implementation of 3D printing and maker spaces in various library settings. Insights, challenges, successes, projects as well as recommendations will be shared. Commonalities across libraries 3D printing technologies and maker space learning areas will also explored. Design/methodology/approach – This paper delves into six case studies of librarians that have implemented 3D printers and/or maker spaces in their libraries. The case studies focus on libraries at three different levels: school, public, and higher education with two case studies from each type. The author of this paper will describe the cases, projects, challenges, successes, along with other aspects of 3D printer, and maker space integration. Findings – 3D printing and maker spaces, while very popular in the field of librarianship can be incredibly exciting to implement but they come with challenges and successes just like any type of new technology. Librarians have to be fearless in implementing this technology, willing to learn on their feet, and be excited to explore. Originality/value – At this time most publications on 3D printing are held in the realm of popular publications (blogs, magazines, zines, etc.). Very little has been written on a wider range of case studies where 3D printers and maker spaces have been integrated into libraries of various types. This paper sets the foundation for further exploration in how 3D printing and maker spaces could be a part of library services.

Full textAbstract:
Two recent studies of the health effects of vegetarian diets reported conflicting results: the EPIC-Oxford study reported a significant increase in strokes among vegetarians compared to meat-eaters among a predominantly Caucasian cohort, while another, performed on Taiwanese Buddhists, reported significantly lower incidence of strokes among vegetarians. This was doubly puzzling given the pronounced decrease in cardiovascular events among the EPIC-Oxford group. In this article, we make a detailed comparison of the actual dietary intake of various food groups by the cohorts in these studies. We then use the nutritional principles of Ayurveda—traditional Indian medicine—to show how these apparently contradictory results may be explained. Systems of traditional medicine such as Ayurveda possess profound knowledge of the effects of food on physiology. Ayurveda takes into account not just the type of food, but also multiple other factors such as taste, temperature, and time of consumption. Traditional cuisines have evolved hand in hand with such systems of medicine to optimize nutrition in the context of local climate and food availability. Harnessing the experiential wisdom of these traditional systems to create an integrative nutrition science would help fight the ongoing epidemic of chronic lifestyle diseases, and improve health and wellness.

Full textAbstract:
A multi-agent system architecture for coordination of just-in-time production and distribution is presented. The problem to solve is twofold: first the right amount of resources at the right time should be produced, then these resources should be distributed to the right consumers. In order to solve the first problem, which is hard when the production and/or distribution time is relatively long, each consumer is equipped with an agent that makes predictions of future needs that it sends to a production agent. The second part of the problem is approached by forming clusters of consumers within which it is possible to redistribute resources fast and at a low cost in order to cope with discrepancies between predicted and actual consumption. Redistribution agents are introduced (one for each cluster) to manage the redistribution of resources. The suggested architecture is evaluated in a case study concerning management of district heating systems. Results from a simulation study show that the suggested approach makes it possible to control the trade-off between quality of service and degree of surplus production. We also compare the suggested approach to a reference control scheme (approximately corresponding to the current approach to district heating management), and conclude that it is possible to reduce the amount of resources produced while maintaining the quality of service. Finally, we describe a simulation experiment where the relation between the size of the clusters and the quality of service was studied.

Purpose This paper aims to analyse two large-scale business case studies for the benefits of using AI, computer science and machine learning to assess, recruit and retain staff. Design/methodology/approach The authors interrogate two large-scale case studies, including metrics on the success of AI in relation to user experience, compatibility, psychometric benchmarking. Findings The authors conclude that AI removes bias from assessment, recruitment and training processes and can save businesses significant time and resources as well as improve the cultural fit and diversity of their recruits. There is a balance to be struck, though, as the systems used are only as good as the science supporting the selection – and humans must ultimately retain the role of decision makers. Originality/value These business case studies are examined in detail for the first time in this paper.

Full textAbstract:
To guarantee the safety and security of a real-time mobile system such as an intelligent transportation system, it is necessary to model and analyze its behaviors prior to actual development. In particular, the mobile objects in such systems must be isolated from each other so that they do not collide with each other. Since isolation means two or more mobile objects must not be located in the same place at the same time, a scheduling policy is required to control and coordinate the movement of such objects. However, traditional scheduling theories are based on task scheduling which is coarse-grained and cannot be directly used for fine-grained isolation controls. In this article, we first propose a fine-grained event-based formal model called a time dependency structure and use it to model and analyze real-time mobile systems. Next, an event-based schedule is defined and the composition of schedules is discussed. Then, we investigate the schedulability of isolation—that is, checking whether a given schedule ensures the isolation relationship among mobile objects or not. After that, we present an automation approach for scheduling generation to guarantee isolation controls in real-time mobile systems. Finally, case studies and simulation experiments demonstrate the usability and effectiveness of our approach.

Full textAbstract:
In recent years, reed bed systems (RBSs) have been widely considered as a valid technology for sludge treatment. In this study are presented results about sludge stabilization occurring within beds in four RBSs, situated in Tuscany (Italy). The results showed that stabilization of the sludge over time occurred in all RBSs, as shown by the low content of water-soluble carbon and dehydrogenase activity, which measures indirectly the overall microbial metabolism, and by the re-synthesis of humic-like matter highlighted by the pyrolytic indices of mineralization and humification. Results about heavy metal fractionation, an appropriate technique to estimate the heavy metal bioavailability and sludge biotoxicity, showed that the process of sludge stabilization occurring in RBSs retains metals in fractions related to the stabilized organic matter, making metals less bioavailable. Moreover, the concentrations of various toxic organic compounds were below the limit of concentration suggested by the European Union's Working Document on Sludge, for land application. The effectiveness of the stabilization processes in RBs was hence clearly proven by the results that measured mineralization and humification processes, and by the low levels of bioavailable heavy metals and toxic organic compounds in stabilized sludges.

Full textAbstract:
Purpose – Puzzle-based storage is a novel approach enabling very dense storage. Previous analytical studies have focussed on retrieval time when one or more usable escort locations (empty slots) are located near the system input/output location, and on simulation results for more complex situations. The purpose of this paper is to extend analytical results to determine retrieval time performance when multiple escorts are randomly located within the system. Design/methodology/approach – Closed-form expressions for retrieval time are developed and proven for cases in which the number of free, randomly placed escorts is equal to one or two. Heuristics with associated worst case bounds are proposed for larger numbers of free escorts. Findings – Puzzle-based storage systems are practical and viable ways to achieve storage density, but retrieval time is heavily dependent upon suitable use of escort locations. Analytical and heuristic methods developed within the paper provide worst-case retrieval time performance in a variety of settings. Research limitations/implications – As the number of free, randomly located escorts increases, optimal analytical solutions are difficult to obtain. Heuristics provide viable retrieval strategies in these situations, and worst-case bounds are relatively easily developed. Originality/value – The primarily contribution of this paper is to make theoretical extensions of optimal methods for puzzle-based storage systems. It motivates additional research in multiple-escort systems and provides insights that should prove useful for the development of 3-dimensional puzzle-based systems and for systems in which concurrent item movement is permitted.

Purpose – The purpose of this paper is to describe the emergence of the mobile library FabLab FryskLab, a project of Bibliotheekservice Fryslân (BSF). There will be special attention on how the business case has been established. Design/methodology/approach – The author examines the broader development of (mobile) FabLabs in libraries. Based on the description of sub-projects that together make the project FryskLab the approach of BSF is described. Findings – The design of a mobile library lab speaks to many people’s imagination. However, achieving a sound business case requires a lot more than just driving around in a bus and providing practical workshops. Developing supporting projects is necessary. Originality/value – At this time most publications on mobile library makerspaces are held in the realm of popular publications (blogs, magazines). Very little has been written on a wider range of case studies where mobile library makerspaces have been integrated into library services. This paper serves as an insight on how BSF developed the FryskLab project.

Full textAbstract:
New management techniques (NMTs) associated with `lean production' - teamworking; just-in-time (JIT) systems; continuous improvement (kaizen); zero defects and so on - have become increasingly influential, particularly in the car industry. This paper reports on case studies and a questionnaire survey of workers in UK and US auto firms operating in Britain. Trade unions have had a significant, albeit variable, impact on the introduction of NMTs. However, not only do the workers have an incomplete perception of the nature of NMTs, but those they do experience would seem to result in an intensification of work, rather than `smarter' work as predicted by the protagonists of NMTs.

Thrombolysis and mechanical thrombectomy have revolutionized the care of patients with acute ischemic stroke. The number of patients who can benefit from these treatments continues to increase as new studies demonstrate that not just time since stroke onset but also collateral circulation influences outcome. Technologies such as telestroke, mobile stroke units, and artificial intelligence are playing an increasing role in identifying and treating stroke. Stroke-systems-of-care models continue to streamline the delivery of definitive revascularization in the age of mechanical thrombectomy.

Full textAbstract:
Seismic resilience is a concept to evaluate the postearthquake functionality of structures that significantly play a critical role in postearthquake rescue and recovery. Indeed, the community is made up of more than just buildings; it is also made up of other subsystems such as hospital and school facilities as well as roads, drainage systems, sewer systems, and electrical power transmission networks. In recent years, the concept of community resilience as a tool for disaster risk management has attracted substantial attention from all parties, such as governments, designers, decision-makers, and stakeholders. Community resilience can be assessed more effectively by using a multi-disciplinary approach that takes into account the community’s uncertainties, as opposed to a single-criteria approach. The global community resilience model must be long-term validated and dependent on the most vulnerable and low-resilience portions of the community, according to a prior study. According to the review of the seismic resiliency studies performed in the recent decades, the frameworks for the quantification assessment of the community resilience are explained. Moreover, several case studies for community resilience and the application of different subsystems are reviewed and elaborated in this paper. Based on these resilience studies, the main challenges on the effectiveness of the resilience assessment are the availability and accessibility of the data, the financial resources, and the cooperation from all the parties.

Co-operative ways of working can be understood as people-centred approaches. This article considers how co-operative ways of working have the potential to support the scaling-out of sustainable and just food systems in the context of Wales through people-centred change. Drawing upon a series of interviews with stakeholders involved in the sustainable and the co-operative food sector within Wales and international case studies, opportunities and challenges facing the scaling-out of sustainable and just food systems are considered. Findings demonstrate the potential of co-operative and community-based approaches to sustainable production, processing, distribution, and trading of healthy food that is affordable, culturally appropriate, and based upon an ethic of justice and care for land, workers, and animals. Community supported agriculture, incubator farms, food hubs, and platform co-operatives are identified as key mechanisms for sustainable and just food systems. Capacity building through education, information, and training are further critical foundations for co-operative and people-centred ways of working. In order to accelerate sustainable and just food futures, community-based participation, networks for training, access to resources and land, and transformative forms of governance, including legislative change, are key. We conclude by highlighting implications for future research into policy transfer and food system transformation.

Full textAbstract:
Observational studies have assessed endemic waterborne risks in a number of countries. Time-series analyses associated increased water turbidity with increased gastroenteritis risks in several public water systems. Several cohort studies reported an increased risk of gastroenteritis in populations using certain public or individual water systems. Although several case-control studies found increased waterborne risks, they also found increased risks associated with other exposures. An increased risk of campylobacteriosis was associated with drinking untreated water from non-urban areas and some tap waters; other significant risks included contaminated poultry and foreign travel. Increased risks of cryptosporidiosis and giardiasis were associated with drinking water in some populations; other risk factors included foreign travel, day care exposures, and swimming. These observational studies provide evidence that some populations may be at an increased risk of endemic or sporadic illness from waterborne exposures, but not all studies found an increased risk. Differences in waterborne risks may be due to differences in water quality. System vulnerabilities and contamination likely differed in the areas that were studied. The information from these studies may help inform estimates of waterborne illness for the US population but is inadequate to estimate a population attributable risk.

Full textAbstract:
Emerging precision agriculture techniques rely on the frequent collection of high-quality data which can be acquired efficiently by unmanned aerial systems (UAS). The main obstacle for wider adoption of this technology is related to UAS operational costs. The path forward requires a high degree of autonomy and integration of the UAS and other cyber physical systems on the farm into a common Farm Management System (FMS) to facilitate the use of big data and artificial intelligence (AI) techniques for decision support. Such a solution has been implemented in the EU project AFarCloud (Aggregated Farming in the Cloud). The regulation of UAS operations is another important factor that impacts the adoption rate of agricultural UAS. An analysis of the new European UAS regulations relevant for autonomous operation is included. Autonomous UAS operation through the AFarCloud FMS solution has been demonstrated at several test farms in multiple European countries. Novel applications have been developed, such as the retrieval of data from remote field sensors using UAS and in situ measurements using dedicated UAS payloads designed for physical contact with the environment. The main findings include that (1) autonomous UAS operation in the agricultural sector is feasible once the regulations allow this; (2) the UAS should be integrated with the FMS and include autonomous data processing and charging functionality to offer a practical solution; and (3) several applications beyond just asset monitoring are relevant for the UAS and will help to justify the cost of this equipment.

Today’s user experience (UX) educators and designers can no longer just focus on creating more usable systems, but must also rise to the level of strategists, using design thinking and human–computer interaction (HCI) solutions to improve academic and business outcomes. Both psychological, designer, and engineering approaches are adopted in this study. An invited program review committee met to review progress of the UX program at the Beijing Normal University (BNUX). They considered issues and challenges facing the program today, and the steps that it could make to develop further. During a recent augmented reality (AR) project on designing future life experience on smart home and wearables, several experiential concepts and prototypes were generated to demonstrate HCI and UX research directions. The committee was impressed by BNUX with its energy, enthusiasm, and a sense of purpose on practicing transdisciplinary teaching and learning activities. Recommendations on the current organization of education, the relation between project-based learning and research, and opportunities for exposure and visibility are provided.

Full textAbstract:
The RUG-III case-mix system is a method of grouping patients in long-term and post-acute care settings. RUG-III groups patients by relative per diem resource consumption and may be used as the basis for prospective payment systems to ensure that facility reimbursement is commensurate with patient acuity. Since RUG-III’s development in 1994, more than a dozen international staff time measurement studies have been published to evaluate the utility of the case-mix system in a variety of diverse health care environments around the world. This overview of the literature summarizes the results of these RUG-III validation studies and compares the performance of the algorithm across countries, patient populations, and health care environments. Limitations of the RUG-III validation literature are discussed for the benefit of health system administrators who are considering implementing RUG-III and next-generation resource utilization group case-mix systems.

The United Nations estimates that by 2050, more than 70% of the world’s population will live in urban areas. In the face of continuing urbanization, how will communities meet the fundamental need for good food? What kinds of public policies, structures, and systems will ensure equitable and just access to food? We argue that urban universities have a responsibility and an extraordinary opportunity to help create equitable community food systems by amplifying community-led planning and policy to strengthen such systems. Drawing on case studies involving the University at Buffalo State University of New York system and its community partners, we describe the ways in which community-university partnerships can leverage policy change to support stronger food systems. We conclude with lessons for such partnerships: the importance of building lasting relationships for policy change, shoring up community capacity, understanding the benefits and burdens for universities and communities, and reimagining universities’ responsibilities to their regions.

Full textAbstract:
Induced polarization (IP) effects are becoming more evident in time-domain helicopter airborne electromagnetic (AEM) data thanks to advances in instrumentation, mainly due to improvements in the signal-to-noise ratio and hence better data quality. Although the IP effects are often manifested as negative receiver voltage values, which are easy to detect, in some cases, IP effects can distort recovered transients in other ways so they may be less obvious and require careful data analysis and processing. These effects represent a challenge for modeling and inversion of the AEM data. For proper modeling of electromagnetic transients, the chargeability of the subsurface and other parameters describing the dispersion also need to be taken into consideration. We use the Cole-Cole model to characterize the dispersion and for modeling of the IP effects in field AEM data, collected by different airborne systems over different geologies and exploration targets, including examples from diamond, gold, and base metal exploration. We determined how multiparametric inversion techniques can simultaneously recover all four Cole-Cole parameters, including resistivity [Formula: see text], chargeability [Formula: see text], relaxation time [Formula: see text], and frequency parameter [Formula: see text]. The results obtained are in good agreement with the ancillary information available. Interpretation of the IP effects in AEM data is therefore seen by the authors as providing corrected electrical resistivity distributions, as well as additional information that could assist in mineral exploration.

They argue that market reaction to the event is predictive of the future effect on the company. Sometimes researchers would like to follow up on these initial event studies to see if the market was correct in its predictions. However, many times the original sample used for the event study does not survive intact into future time periods, which then raises the issue of survivor bias. This paper examines one such event study in which the markets react favorably to announcements that ERP systems are being implemented. However, only 55% of the firms in the original sample survive through 2009, making any follow-up study subject to the survivor bias argument. The study examines the circumstances related to the non-survivors and, using proxies for the missing data, concludes that the results of a follow-up study would not have been impacted by survivor bias.

ABSTRACT The need for continuous auditing and continuous monitoring (CA/CM) has increased in the global digital economy. Modern computer-based systems make it possible to measure and monitor business processes at an unprecedented level of detail in a real- or near real-time basis. This empowers auditors to become increasingly dependent on computer technology and software tools. While there is a growing body of literature related to this domain, there is a need for empirical evidence from actual implementations that document these systems in detail. In this research, we perform such an investigation on three CA/CM systems, namely SAPSECURE, CAMAP, and Bagheera-S™.

Full textAbstract:
Microwave breast imaging has seen increasing use in clinical investigations in the past decade with over eight systems having being trialled with patients. The majority of systems use radar-based algorithms to reconstruct the image shown to the clinician which requires an estimate of the dielectric properties of the breast to synthetically focus signals to reconstruct the image. Both simulated and experimental studies have shown that, even in simplified scenarios, misestimation of the dielectric properties can impair both the image quality and tumour detection. Many methods have been proposed to address the issue of the estimation of dielectric properties, but few have been tested with patient images. In this work, a leading approach for dielectric properties estimation based on the computation of many candidate images for microwave breast imaging is analysed with patient images for the first time. Using five clinical case studies of both healthy breasts and breasts with abnormalities, the advantages and disadvantages of computational patient-specific microwave breast image reconstruction are highlighted.

In this journal, discussion is given to analyse the improved round robin algorithm more thoroughly. Round robin algorithm plays a significant role to be used in embedded systems. Round robin algorithm usually applied in real-time systems. Here, three case studies are given, and also the analysis of each case study. Comparisons are given about the average turn around time and average waiting time, also number of context switching between the three case studies. Improved round robin algorithm, is a modification from the generic round robin algorithm. In improved round robin algorithm if the remaining burst time is less than the time slice that is allocated, then the currently running process is continue to be executed. Then finish the currently running process from ready queue and execute the next ready queue. Three case studies are given with three different time quantum, which are 3, 4, and 5 ms. The result of this case study analysis is that, the efficiency of the quantum 5 ms is the most effective one. There is an increase of 50% context switching from quantum 3 to quantum 5. And for average turn around time we get 13.13% reduction in efficiency. While in average waiting time we get reduction 12.08% efficiency.

Until the end of the 1950s the tram was the most important mode of urban transport in Germany. In the following 30 years drastic cuts were made in the tram network. This trend has now been reversed: new tramways are being built and old ones upgraded. Five case studies represent different developments of tram and light rail systems in German cities: (a) Hannover, which is typical of the stepwise development of a tram system into a partly underground light rail system; (b) Karlsruhe, where the most intensive utilization of railroad tracks is taking place, including the world's first dual-current tram; (c) Oberhausen, where for the first time in Germany a tram was reintroduced in 1996; (d) Saabrücken, which represents the second case of tram reintroduction according to the Karlsruhe model in 1997; and finally (e) Munich, where dense U-Bahn and S-Bahn networks are going to be complemented by new or reopened tram lines.

Abstract Analysis described in the paper were made in the frame of the PROZA (Operational decisionmaking based on atmospheric conditions, http://projekt-proza.pl/) project co-financed by the European Union through the European Regional Development Fund. One of its tasks was to develop an operational forecast system, which is going to support different economies branches like forestry or fruit farming by reducing the risk of economic decisions with taking into consideration weather conditions. The main purpose of the paper is to describe the method of the MCSs (Mesoscale Convective Systems) tracking on the basis of the MSG (Meteosat Second Generation) data. Until now several tests were performed. The Meteosat satellite images in selected spectral channels collected for Central Europe Region for May 2010 were used to detect and track cloud systems recognized as MCSs in Poland. The ISIS tracking method was applied here. First the cloud objects are defined using the temperature threshold and next the selected cells are tracked using principle of overlapping position on consecutive images. The main benefit of using a temperature threshold to define cells is its efficiency. During the tracking process the algorithm links the cells of the image at time t to the one of the following image at time t+dt that correspond to the same cloud system. Selected cases present phenomena, which appeared at the territory of Poland. They were compared to the weather radar data and UKMO UM (United Kingdom MetOffice Unified Model) forecasts. The paper presents analysis of exemplary MCSs in the context of near realtime prediction system development and proves that developed tool can be helpful in MCSs monitoring.

Full textAbstract:
The waste-heat recovery in batch processes has been studied using the pinch-point method. The aim of the work has been to investigate theoretical and practical approaches to the design of heat-exchanger networks, including heat storage, for waste-heat recovery in batch processes. The study is limited to the incorporation of energy-storage systems based on fixed-temperature variable-mass stores. The background for preferring this to the alternatives (variable-temperature fixed-mass and constant-mass constant-temperature (latent-heat) stores) is given. It is shown that the maximum energy-saving targets as calculated by the pinch-point method (time average model, TAM) can be achieved by locating energy stores at either end of each process stream. This theoretically large number of heat-storage tanks (twice the number of process streams) can be reduced to just a few tanks. A simple procedure for determining a number of heat-storage tanks sufficient to achieve the maximum energy-saving targets as calculated by the pinch-point method is described. This procedure relies on combinatorial considerations, and could therefore be labeled the “combinatorial method” for incorporation of heat storage in heat-exchanger networks. Qualitative arguments justifying the procedure are presented. For simple systems, waste-heat recovery systems with only three heat-storage temperatures (a hot storage, a cold storage, and a heat store at the pinch temperature) often can achieve the maximum energy-saving targets. Through case studies, six of which are presented, it is found that a theoretically large number of heat-storage tanks (twice the number of process streams) can be reduced to just a few tanks. The description of these six cases is intended to be sufficiently detailed to serve as benchmark cases for development of alternative methods.

Full textAbstract:
We explore the use of deep neural networks for anomaly detection of industrial systems where the data are multivariate time series measurements. We formulate the problem as a self-supervised learning where data under normal operation is used to train a deep neural network autoregressive model, i.e., use a window of time series data to predict future data values. The aim of such a model is to learn to represent the system dynamic behavior under normal conditions, while expect higher model vs. measurement discrepancies under faulty conditions. In real world applications, many control settings are categorical in nature. In this paper, vector embedding and joint losses are employed to deal with such situations. Both LSTM and CNN based deep neural network backbones are studied on the Secure Water Treatment (SWaT) testbed datasets. Also, Support Vector Data Description (SVDD) method is adapted to such anomaly detection settings with deep neural networks. Evaluation methods and results are discussed based on the SWaT dataset along with potential pitfalls.

Heating systems such as heat pumps and combined heat and power cycle systems (CHP) represent a key component in the future smart grid. Their capability to couple the electricity and heat sector promises a massive contribution to the energy transition. Hence, these systems are continuously studied numerically and experimentally to quantify their potential and develop optimal control methods. Although numerical simulations provide time and cost-effective solutions for system development and optimization, they are exposed to several uncertainties. Hardware in the loop (HiL) approaches enable system validation and evaluation under different real-life dynamic constraints and boundary conditions. In this paper, a HiL system of a heat pump testbed is presented. It is used to present two case studies. In the first case, the conventional heat pump testbed operation method is compared to the HiL operation method. Energetic and dynamic analyses are performed to quantify the added value of the HiL and its necessity for dynamics analysis. In the second case, the HiL testbed is used to validate a model of a single family house with a heat pump participating in a local energy market. The energetic analysis indicates a deviation of 2% and 5% for heat generation and electricity consumption of the heat pump model, respectively. The model dynamics emphasized its capability to present the dynamics of a real system with a temporal distortion of 3%.

Three Resilient Food Systems training workshops were delivered in Bogor, Indonesia, Suva, Fiji, and Port Vila, Vanuatu. The workshops provided young and early-career professionals with the latest international thinking on food systems and resilience. The workshop teaching material was based on the IFSTAL (Interdisciplinary Food System Teaching and Learning; www.ifstal.ac.uk) programme initially developed in the United Kingdom. The intensive six-day workshop programme integrates learning across three connected themes: food systems and resilience concepts, soft system methodology, and personal skills and development. Each workshop is locally contextualised with field trips, local inspirational guest speakers, and local real-world food system case studies. Throughout the duration of the workshop, participants apply new concepts and methodologies to their case studies, thereby enhancing their understanding and learning. Participant evaluation of the workshops was overwhelmingly positive, and pleasingly, participants reported positive learning outcomes across all three learning themes. These workshops represent just the initial step in a necessarily long and sustained effort to establish a community of food system professionals across Indonesia and Pacific Island states.

This paper explores the ethical and legal pedagogy of the current debates on “reforming” Muslim societies, whether they claim to reform social and legal systems, reform educational institutions, or liberate Muslim women. Since these debates claim to achieve balance in global or domestic conflicts, I address the foundations of these debates by answering three questions:Are the rationales for American and/or European governments' interventions justified?;Can the discipline of civil law help in rethinking Islam for Muslims; andAre Muslims themselves ready to critically address the use and misuse of Islam's primary sources (the Qur'an and particularly the Hadith) in their rethinking of Islam?I argue that rather than seeking to “reform others,” in this case Muslims with an elitist attitude and sometimes violent interventions, we scholars of law and religion, scholars of Islam, policy-makers, and social justice researchers would be better off if:we thought of Islam as a religio-moral rational worldview, rather than a set of laws,we recognized Muslims as subject to historical transformation, like any other religious groups, and understood how they developed their present views of Islam, andwe considered our own real responsibilities to address the forms of global injustices as powerful shapers of world politics, particularly the politics of difference—the view that the “other” is inferior, and women's role as mostly complementary to men.

The proposed this research is to inspire a systems thinking theory and a value chain management, building a business model that prioritizes customers. The objective of this paper is to find out how accounting techniques can optimize of resource utilization wihich would lead in creating value. The second objective is to minimize the lack of conventional accounting using the accounting method that appears.
The method in this shis paper is a qualitative research by considering the inductive method designed as a single case study.
Empirical data is used based on classic single case control studies that embedded designs including survey data, academic papers theoretical reviews, data collection from interviews, annual reports and documents collected from case companies.
The research found that the management accounting system could be integrated in the framework of Just in Time (JIT) + Total Cost (TC) + Time Driven- Activity Based Costing (TD-ABC) + Balance Scorecard (BSC) to develop lean accounting. The utilization of resource is optimized after non-value added activities are eliminated.

In this review, we collect, for the first time, old and new research results, and present future perspectives on how hadron production, in high-energy scattering processes, can experimentally probe fundamental questions of quantum gravity. The key observations that ignited the link between the two arenas are the so-called “color-event horizon” of quantum chromodynamics, and the (de)accelerations involved in such scattering processes. Both phenomena point to the Unruh (and related Hawking)-type effects. After the first pioneering investigations, such research studies continued, including studies of the horizon entropy and other “black-hole thermodynamical” behaviors, which incidentally are also part of the frontier of the analog gravity research itself. It has been stressed that the trait d’union between the two phenomenologies is that in both hadron physics and black hole physics, “thermal” behaviors are more easily understood, not as due to real thermalization processes (sometimes just impossible, given the small number of particles involved), but rather to a stochastic/quantum entanglement nature of such temperatures. Finally, other aspects, such as the self-critical organizations of hadronic matter and of black holes, have been recently investigated. The results of those investigations are also summarized and commented upon here. As a general remark, this research line shows that we can probe quantum gravity theoretical constructions with analog systems that are not confined to only the condensed matter arena.

Purpose The purpose of this paper is to provide a new approach involving guidelines and supporting techniques that guarantees all needed space for appropriate product maintenance. Design/methodology/approach The approach is based on two major areas: field survey to understand how maintainability parameter is applied and converge theory and practice into a systematic space claim method using computer-aided design (CAD) systems to assure proper maintenance procedures at design stages. Findings Case studies from a truck industry conducted following the proposed approach contrast the savings that can be achieved by using a proper space claim for aftermarket needs against an unsuitable level of participation by maintenance personnel during the design development. Research limitations/implications This approach is highly dependent on maintenance experts with suitable skills on CAD systems. Practical implications Products developed according to the approach envisaged can result in following aspects: lower repair time, better maintenance procedures on key components, easier preventive maintenance, less need for special tools, more ergonomic design, better communication between design and service engineers, simplicity and less complex training. Social implications Further research on maintainability will provide new information on how to apply this parameter on product development process (PDP), so design teams can better understand and address this relevant issue. The proposed method has been introduced in the PDP of a major multinational automotive company. Originality/value A new process is presented, considering the protection of needed spaces for maintenance procedures throughout the PDP, diverging to other studies that only propose analysis addressing maintainability at singular point in time during the product development. In just one case study presented, savings of US$1.3m were achieved by applying this space claim approach.

Purpose An alignment between financial and operational measures is an essential element to capture the lean productivity improvements enabling supply chain sustainability. With the aim of supporting small and medium-sized enterprises (SMEs) in addressing corporate sustainability challenges, this study aims to examine the impact of leanness on supply chain sustainability, and the moderating role of sustainability control systems (SCS) on the relationship between leanness and supply chain sustainability. Design/methodology/approach Drawing on lean manufacturing and the levers of control framework, survey data was collected from 106 manufacturing SMEs in Sri Lanka. Moderated multiple regression analysis was used to test the proposed hypotheses. Findings The study finds that lean manufacturing practices, such as just-in-time deliveries, quality management, environmental management and employee involvement show a significant positive impact on supply chain sustainability. As proposed, the interactive use of SCS shows a significant, positive moderating impact on the relationship between employee involvement and social supply chain sustainability. The diagnostic use of SCS negatively moderates the relationships between just-in-time deliveries and economic supply chain sustainability, and environmental management and economic supply chain sustainability. However, both interactive and diagnostic uses of SCS do not show any significant moderating impact between lean manufacturing and environmental supply chain sustainability. Research limitations/implications The following limitations should be taken into account in interpreting the results and implications of this study. Firstly, the study refers to supply chain sustainability as environmental, social and economic sustainability. As these concepts represent broader perspectives of sustainability, and no consensus on how to measure has yet been agreed, future studies may focus on other variables that might capture different perspectives of supply chain sustainability. Secondy, future researchers may further extend the role of SCS (including all four control systems – belief, boundary, interactive and diagnostic) in examining the impact of leanness on supply chain sustainability. Thirdly, this study has considered a sample of manufacturing SMEs in the Western province in Sri Lanka. The results should be carefully generalised to other manufacturing organisations in Sri Lanka and beyond. Finally, future studies may also investigate the impact of leanness on supply chain sustainability by using alternative methodologies, such as multiple case studies. Originality/value SMEs are more likely to focus on diagnostic control systems with the aim of promoting economic supply chain sustainability. However, the findings reveal that manufacturing SMEs in the developing country context lack strong SCS to enable supply chain sustainability.

The proportional–integral plus Clegg integrator (PI + CI) controller is a hybrid extension of the proportional–integral (PI) controller that is able to overcome fundamental limitations of the linear and time-invariant control systems, potentially obtaining faster responses without increasing overshooting. This work focused on the analysis and design of PI + CI controllers and reset controllers in general, for the case of parallel multiple-input single-output (MISO) systems, extending previous design methods developed for the single-input single-output (SISO) case. Several design strategies were developed: one for first-order MISO plants achieving a flat response with a finite settling time, and for second-order MISO plants obtaining a fast response with a reduced overshoot and settling time in comparison with non-hybrid strategies. Several case studies were also developed to illustrate the potential of the proposed methods.

Digital technologies, autonomous systems, and artificial intelligence are seen as mater‑of‑course parts of the world today. Japan, as one of the leading countries in technological innovations, is the most advanced in terms of approach to digital society. Japanese society and government have been working on a new concept of life where all the digital technologies will communicate through the internet. Society organised in this way is called Society 5.0 – super Smart society. In Japan, this concept is centred about seventeen sustainable goals (United Nations, 2018). Society 5.0 is a reaction to the fundamental technological revolutionary changes known today as Industry 4.0. Thus, Society 5.0 is the consequence of a technological revolution that will eventually affect not just the production but all parts of today’s life as well. The new technologies evoke some fundamental philosophical and existential questions. How can technological advances improve the prosperity and functioning of society? What about the privacy and security of all the users? The present paper compares Japan and the Czech Republic from the perspective of digitalization of society based on three main aspects: government programs supporting digital technologies, number of technically educated experts and investments in science and research. The objective is to find out how much the Czech Republic has advanced towards preparations for digital society.

This paper studies likelihood-based estimation and tests for autoregressive time series models with deterministic trends and general disturbance distributions. In particular, a joint estimation of the trend coefficients and the autoregressive parameter is considered. Asymptotic analysis on the M-estimators is provided. It is shown that the limiting distributions of these estimators involve nonlinear equation systems of Brownian motions even for the simple case of least squares regression. Unit root tests based on M-estimation are also considered, and extensions of the Neyman–Pearson test are studied. The finite sample performance of these estimators and testing procedures is examined by Monte Carlo experiments.

Full textAbstract:
Waiting for low–income housing is an increasingly common experience of the urban poor in both the global North and South, although little attention has been paid to its effects. Engaging a growing literature on time in systems of social provision, this article presents an ethnographic case study of waiting among poor housing–seekers in a peripheral district of Santiago, Chile. While illustrating how waiting is produced by state policies and practices that position homeless city–dwellers as passive clients, it challenges existing studies that argue that waiting produces durable submission to dominant state projects. In contrast, it shows that housing–seekers in Santiago actively negotiated a denigrating temporality of state provision through multiple practices, including collective contestation of arbitrary delays. By dissecting the conditions that enabled contentious responses to waiting for housing in Chile, this article aims to elucidate how such temporal contestation may emerge (or be precluded) in other contexts.

Full textAbstract:
This paper studies the problem of fault detection for continuous time linear switched systems in the presence of disturbance. For this purpose, a fault detection sliding mode observer approach is designed to generate the residual signal. To minimize the effect of disturbance from the residual, the problem is formulated into H∞ filtering technique to increase more robustness. To deal with the issue of the switched systems stability, the Lyapunov-Krasovskii functional method is utilized along with average dwell time, and linear matrix inequalities are formulated to derive the sufficient conditions. The residual signal is evaluated, and an adaptive threshold is computed for both modes of the switched system. Finally, a simulation example for a case study of boost converter and a numerical example with both abrupt and incipient faults are illustrated to prove the efficacy of the proposed method.

Evaluation of regional psychiatric services is essential for effective and economical planning and requires a complete and accurate source of data about individuals in the system. Routinely collected statistics describe only events, and cannot link data about individuals over time. This is possible with record linkage systems (or case registers) which are systematic standardized data collections about individuals’ contacts with specified facilities over time. Such data bases have a wide range of clinical, epidemiological and administrative functions. The confidentiality of such systems is of paramount importance and is maintained by several safeguards.

An ongoing collection of linked data is required for many types of research and particularly for service evaluation. In times of cost constraints and diminishing resources, it is essential to deliver psychiatric services in the most effective and cost efficient manner possible.
