Abstract:
The study examined inventory management and organisational efficiency. The classical inventory management techniques were applied to an organisation’s inventory system. A door sales company in Ilorin, Nigeria that volunteered information on the basis of anonymity was used and relevant data were collected on six types of doors; panel, flush, sliding, folding and as well as manual and electronic garage doors. The company had no scientific inventory management strategy but the EOQ, inventory cycle time and reorder level were computed for the six doors using the average values of the data obtained for 2011-2017. The results show that the company can minimise its total inventory cost by consciously adopting an inventory management policy of ordering 55 panel doors, 41 flush doors, 41 sliding glass doors, 18 folding doors, 18 manual garage doors and 8 electronic garage doors respectively every cycle time of 17, 14, 17, 30, 35 and 34 days respectively or by placing the above orders each time the inventory level of panel doors, flush doors, sliding glass doors, folding doors, manual garage doors and electronic garage doors fall to 32, 24, 24, 5, 3 and 2 respectively and thus minimise the total cost of inventory.

Abstract:
A survey was conducted in local municipalities in the Tshwane region of Gauteng Province in South Africa in order to assess and evaluate the efficiency with which municipal waste is collected, disposed of, processed and recycled by local municipalities in Tshwane based on data gathered from 1,035 businesses. Efficiency in waste management was assessed by using a structural time-based model designed for evaluating efficiency as a function of the length of time required to manage and process municipal waste. Adherence to municipal bylaws and procedures recommended for solid waste management by businesses by the City of Tshwane was graded based on ISO 14000 and ISO 14031 standards and guidelines. The study found that efficiency in waste management was adversely influenced by lack of adherence to municipal bylaws and regulations, wrong perception on the benefits of proper waste management, and failure to provide customers with waste disposal bins, in a decreasing order of importance.

Abstract:
Real-time monitoring and optimization of production and logistics processes significantly improve the efficiency of production systems. Advanced production management solutions require real-time information about the status of products, production, and resources. As real-time locating systems (also referred to as indoor positioning systems) can enrich the available information, these systems started to gain attention in industrial environments in recent years. This paper provides a review of the possible technologies and applications related to production control and logistics, quality management, safety, and efficiency monitoring. This work also provides a workflow to clarify the steps of a typical real-time locating system project, including the cleaning, pre-processing, and analysis of the data to provide a guideline and reference for research and development of indoor positioning-based manufacturing solutions.

Abstract:
The goal of workflow system is to guarantee that the right activities are executed and completed within the correct and ideal time periods via automation, moreover, in order to help a company to be sufficiently competitive, the workflow system it adopts should be able to ensure activities are carried out to the maximum extent as possible and to manage several workflow instances at the same time. Hence, sufficient consideration of temporal constraints and efficiency should be taken into the design process of workflow system. This paper proposes a model of workflow control based on time axis which is able to ensure one or more workflows to advance in correct time period efficiently and precisely.

Abstract:
In this work, a probabilistic framework is presented for real-time assessment of wave and surge risk for hurricanes approaching landfall. This framework has two fundamental components. The first is the development of a surrogate model for the rapid evaluation of hurricane waves, water levels, and runup based on a small number of parameters describing each hurricane: hurricane landfall location and heading, central pressure, forward speed, and radius of maximum winds. This surrogate model is developed using a response surface methodology fed by information from hundreds of pre-computed, high-fidelity model runs. For a specific set of hurricane parameters (i.e., a specific landfalling hurricane), the surrogate model is able to evaluate the maximum wave height, water level, and runup during the storm at a cost that is more than seven orders of magnitude less than the high fidelity models and thus meet time constraints imposed by emergency managers and decision makers. The second component to this framework is a description of the uncertainty in the parameters used to characterize the hurricane, through appropriate probability models, which then leads to quantification of hurricane-risk in terms of a probabilistic integral. This integral is then efficiently computed using the already established surrogate model by analyzing thousands of different scenarios (based on the aforementioned probabilistic description). Finally, by leveraging the computational simplicity and efficiency of the surrogate model, a simple stand-alone PC-based risk assessment tool is developed that allows non-expert end users to take advantage of the full potential of the framework. An illustrative example is presented that considers applications of these tools for hurricane risk estimation for Oahu. The development of cyber-infrastructure at the University of Notre Dame to further support these initiatives is also discussed.

Pratt and Whitney is expecting an increase in demand for new engines and for parts supportive of aftermarket service, maintenance, and repair. To avoid expensive capital investments in additional production capacity, Pratt is taking several approaches to better utilize existing capacity. In a business where historically margins have been high, demand was flat, and in some years decreasing, and staffing had relatively low turnover, conditions were not forcing leaders to focus on identifying ways to eliminate waste or adapt cutting edge manufacturing analytics. With the introduction of new and innovative products, Pratt & Whitney is quickly approaching conditions where demand will outpace capacity. Additionally, demographics of the employee base has started to hit a point where many key and tenured employees have started to and will continue to retire leaving a knowledge gap behind.
To attack this growing problem, Pratt is taking several approaches to win more efficiency and effectiveness out of existing capacity. These include lean initiatives supported by connected and real time manufacturing technologies. Sensors and monitors are primarily used to gather data about machine condition and performance which is fed back to calculate Overall Equipment Effectiveness (OEE), a lean metric used to identify waste in the manufacturing process. The production team in Columbus has done a lot over the past few years to increase production, but as utilization rates increase, they are looking for new ways to expand capacity. The problem faced by management is identifying and reacting to losses as they occur, rather than retroactively, which is caused, in part, by inadequate access to the data.
This problem of reacting timely to losses is exacerbated by attrition of experienced workers who had tribal knowledge of the processes and how to react, whereas newer employees have not developed those reactionary instincts yet. Pratt & Whitney in Columbus has been collecting and storing data from their forge presses for years; accessing and analyzing that data in real time and integrating decision making based off that data has not been a part of their process. Using machine state tags, that is logic based off Programable Logic Controllers (PLCs) to tell users if the machine is in a run state, going through a changeover, or sitting idle, management can view the state of machines anywhere they can access the Pratt network. This data has also been used to calculate production efficiencies by part number by asset by calculating actual cycle times and comparing them to the engineering design time per part.
This is fed as an input to the new scheduling tool developed over the past few months which is meant to capture the intricacies of how different materials perform on different presses and optimize total production time by maximizing tool life among the presses. I have identified key inputs and business analytics processes to evaluate suboptimal efficiencies in the production process. This has affected the manner in which Pratt & Whitney in Columbus conducts business and permeated throughout the management structure to be included in events from daily production meetings all the way up to weekly executive report outs. Initial results show scheduling efficiency would improve output up to 8%, and the data has been utilized to uncover other areas for efficiency gains amounting to a 25% go get by the end of the year.
This research has shown that a data rich environment can present you with a vast array of opportunities if the data can be aggregated and interpreted timely enough to feed the decision-making process of production and if the organization has a culture to embrace it.

Abstract:
Les plates-formes multi/multi-cœurs organisées en clusters représentent des solutions prometteuses pour fournir des performances de calcul élevées et une efficacité énergétique optimisée dans les systèmes embarqués modernes. Ces plates-formes prennent souvent en charge la gestion dynamique tension/fréquence (DVFS) par cluster, ce qui permet à différents clusters de modifier leurs propres niveaux tension/ fréquence indépendamment. La complexité et le dynamisme croissants des applications sur ces plates-formes rendent nécessaire la gestion en ligne des ressources. Ce mémoire se concentre sur les méthodes de gestion en ligne des applications sur des systèmes multi/multi-cœurs en cluster pour améliorer l'efficacité énergétique. Cette thèse présente différentes stratégies de gestion qui permettent d'estimer l'influence mutuelle entre l'allocation des applications et la configuration en tension/fréquence des clusters afin d'obtenir respectivement une optimisation locale au sein d'un cluster et une optimisation globale dans l'ensemble du système. Les stratégies proposées permettent d'obtenir des solutions de gestion optimisées avec moins de complexité que les stratégies existantes. De plus, cette thèse présente une nouvelle approche de modélisation et de simulation qui permet d'évaluer les stratégies de gestion en ligne dans les systèmes multi/multi-cœurs pour garantir que les contraintes du système sont pleinement respectées. L'approche de simulation proposée est validée à l'aide d'un cadre de modélisation et de simulation industrielle
Cluster-based multi/many-core platforms represent promising solutions to deliver high computing performance and energy efficiency in modern embedded systems. These platforms often support per-cluster Dynamic Voltage/Frequency Scaling (DVFS), allowing different clusters to change their own v/f levels independently. The increasing application complexity and application dynamism on such platforms arise the need for run-time management. This dissertation focuses on the run-time management of applications on clusterbased multi/many-core systems to improve energy efficiency. Towards the run-time management purpose, this dissertation presents different management strategies that estimate the mutual influence between application mapping and cluster v/f configurations to respectively achieve local optimization within a cluster and global optimization in the overall system. The proposed management strategies can achieve near-optimal management solutions with less strategy complexity compared to state-of-theart strategies. ln addition, this dissertation presents a new modelling and simulation approach that allows the evaluation of run-time management strategies in multi/many-core systems to guarantee that system constraints are fully met. The proposed simulation approach is validated using an industrial modelling and simulation framework

Abstract:
Traditional sales systems have been disrupted by technological developments. In order to  adapt, companies are changing the way they interact with their customers in business-to-business markets. In the last three decades, multi-channel strategies have spurred the proliferation of different sales channels and new ways of managing sales systems. The purpose of this research was to investigate what should be considered when managing multi-channel sales systems with the objective of increasing sales efficiency. The study has investigated current utilisation of multi-channel sales systems in the context of a business-to-business setting in industrial companies that are involved in the Swedish automotive industry. Multi-channel sales systems can be utilised to achieve many different objectives. However, this research pays specific attention on how to improve sales efficiency by utilising multi-channel sales systems in the context of a business-to-business setting. The research employed an explorative case study, where semi-structured and structured interviews were conducted at a case company and at companies that are first or second tier suppliers in the Swedish automotive industry. The qualitative data were analysed using thematic analysis. The empirical findings indicate that the most prevalent measure for increasing sales efficiency is to prioritise and allocate customers based on economic attractiveness. Furthermore, the key issues that impede sales efficiency in multi-channels sales system are misaligned sales activities, deficient prioritisation procedures, insufficient promotion of customer value and inadequate focus on customers. The findings highlight key areas to address and may provide guidelines for the design and management of multi-channel sales systems with the specific purpose of obtaining sales efficiency. The implications of this research are mainly practical and are aimed at supporting sales managers, or individuals in similar positions engaged in multi-channel sales system design and management, in obtaining sales efficiency. Managers should focus on aligning sales activities across the whole  sales system, allocate customers according to prioritisation and stay in line with market developments by understanding customer behaviours and perceptions.

Abstract:
Today's fast-paced and increasingly competitive market has added pressure on companies and NPD-teams to improve both the quality of the products they provide, as well as the speed in which the products are introduced to the market. The main purpose within this study was to investigate two research questions; (a) How can various management- and leadership styles improve time efficacy without impairing the successes of the FFE of the NPD process; and (b) How can/does the uncertainty within the FFE affect project managers within the NPD process?Qualitative methods have been used within this study to gain a greater understating of the tasks and activities management have applied within the FFE to reduce and save time. A multiple case study, in the form of interviews, was performed in order to obtain raw empirical data. Eight interviews were conducted with individuals whom possessed managerial roles such as project managers, within the NPD process. The information was later analyzed and evaluated with the help of a thematic analysis.The main findings within this thesis contradict previous studies and literature which state the need for “more time” within the FFE of the NPD process. The result within this study suggest that project managers do not seek to extend the time provided within the FFE, rather identify task and methods which can enable them to use the time afforded wisely and efficiently. The managers do not seek to eliminate any tasks or activities; however, they do wish to identify less relevant activities in order to spend more time on valuable and beneficial tasks which increase the likely-hood of developing high quality products.

Li & Fung works with over 10,000 factories distributed across 50 countries to design, produce, and deliver hard- and soft- goods to over 2,000 apparel and consumer goods customers. An increasingly prevalent focus of the industry, driven both by regulation and consumer preferences, is to measure, benchmark, and reduce the overall environmental impact of the supply chain. Currently the measurement mechanisms in place rely on a traditional two-phase approach involving factory self-reporting and verification via independent audits. The scope of this project is to assess the efficacy of currently available measurement data in order to inform the requirements for real-time collected data. This project will be broken into four phases. First, existing industry data sources will be described and evaluated in order to assess data quality, understand requirements, and provide recommendations for future data collection. Second, the features of the data will be analyzed in order to develop an understanding of the underlining relationships. Third, using a set of selected features from the second phase, a predictive clustering algorithm for factory-level resource efficiency will be developed and used to benchmark factories. Finally, an analysis will be performed to evaluate the requirements of real time data and how real-time data could improve the benchmarking tool and future tools and services.

Full text
Abstract:
The Thai State Railway Authority (RSR) is a public enterprise in Thailand. As an organization its performance is subject to the argument of contingency theorists that operating efficiency is dependent upon various factors both in the internal and external environments of the enterprise. Most of the internal factors are those that organization theorists in the developed world have identified such as goals and objectives, resources, and organization structures. Meanwhile, external factors such as political, economic and social conditions of the society are regarded as indirect factors that have less importance than do the internal factors. Scholars of the developing world have argued that political, social and economic conditions in the society are as important as internal factors. These factors may have a very significant influence on the enterprises and on the society as a whole. Consequently, public enterprises in developing countries always encounter the same problem of operating inefficiency. The RSR is selected as a case study because of its advantages over the other public enterprises in Thailand in terms of size of operation, length of service, and data availability. For the purpose of this project, data are collected from 1960 to 1984 for longitudinal analysis. The methods of analysis are divided into two major sections: simple regression testing and multiple regression testing. The principal component technique is used in both testings to reduce variables to a smaller number for further analysis. The simple regression tests yielded mixed results, but the multiple regression tests resulted in significant relationships. The three new factors derived from the factor analysis technique were labeled as "the organizational pressures," "the socio-political downturn," and "the public criticisms." They explained 84% of all the variance of operating efficiency. The other 16% was the effect of other factors including the management skills, which were excluded from this analysis.

Abstract:
With the growing concerns about energy shortage and demand supply imbalance, demand side management (DSM) activities has found its way into the mining industry. This study analyzes the potential to save energy and energy-costs in underground mine ventilation networks, by application of DSM techniques. Energy saving is achieved by optimally adjusting the speed of the main fan to match the time-varying flow demand in the network, which is known as ventilation on demand (VOD). Further cost saving is achieved by shifting load to off-peak or standard times according to a time of use (TOU) tariff, i.e. finding the optimal mining schedule. The network is modelled using graph theory and Kirchhoff’s laws; which is used to form a non-linear, constrained, optimization problem. The objective of this problem is formulated to minimize the energy cost; and hence it is directly given as a function of the fan speed, which is the control variable. As such, the operating point is found for every change in the fan speed, by incorporating the fan laws and the system curve. The problem is solved using the fmincon solver in Matlab’s optimization toolbox. The model is analyzed for different scenarios, including varying the flow rate requirements and tariff structure. Although the results are preliminary and very case specific, the study suggests that significant energy and energy-cost saving can be achieved in a financially viable manner.

Abstract:
Magnetic Resonance Imaging (MRI) can be used in many clinical situations, but they are limited by high costs and time-consuming properties. Most focus has been on improving the technical side of MRI, and not as much on process improvements. Long access times to MRI examinations can be the cause of inefficient workflows of the departments, which can cause adverse effects for the patients. A market research of the Swedish radiology departments that perform MRI examinations resulted in a wide range of median access times, ranging from approximately 21 days to 130 days. This indicates potential for improvement in their workflows. To improve workflows, they need to be analysed and measured. A model for process time efficiency analysis in MRI departments was created in this project which can assess 5 different metrics. These metrics are number of examinations, examination time, turnover time, scanner utility, and scheduling consistency. Potential improvement strategies to reduce the access times associated with the metrics in the model is discussed. Examination time is mostly affected by the technique and the examination protocol but making the change to an abbreviated version of the protocol has the potential to significantly reduce examination time. This is especially useful for screening purposes. Reduction in turnover time can be achieved by analysing the process in between examinations and making suitable changes in preparation of patients and examinations, and in architecture for a more streamlined throughput. The scheduling process has a large impact on efficiency and reduction in access times and increasing utility rate. It is important for the scheduling process to be flexible to increase efficiency. As a result of this report, the conclusion is that a benchmarking project could be conducted on Swedish radiology departments to determine best practices in workflows.
Magnetresonanstomografi (MRT) kan användas i många kliniska situationer, men de är begränsade av höga kostnader och tidskrävande egenskaper. Störst fokus har tidigare varit på de tekniska aspekterna av MRT och inte lika mycket på processförbättring. Långa väntetider till MRT-undersökningar kan vara orsaken av ineffektiva arbetssätt på avdelningarna, vilket skapar negativa effekter för patienter. En marknadsundersökning av de svenska radiologiavdelningarna som utför MRT-undersökningar resulterade i ett stort spann av väntetider, från ungefär 21 dagar till 130 dagar. Detta indikerar förbättringspotential i deras arbetssätt. För att förbättra arbetssätt måste de analyseras och mätas. En modell för att mäta effektivitet för processtder på MRT-avdelningar skapades i detta projekt med fem olika mätvärden. Dessa mätvärden är antal undersökningar, undersökningstid, tid mellan undersökningar, användningsgrad av maskiner och efterföljande av bokningstid. Potentiella förbättringsstrategier för att minska väntetider länkade till mätvärderna i modellen diskuteras. Undersökningstiden påverkas mest av tekniken och protokollet för undersökningen, men genom att byta till ett förkortat protokoll kan undersökningstiden minskas avsevärt. Detta kan vara särskilt användningsbart vid screeningundersökningar. Tiden mellan undersökningar kan minskas genom att analysera processen mellan undersökningarna och göra ändringar i förberedelser av patient och undersökning samt arkitektuella ändringar för en mer effektivserad genomströmning. Bokningsprocessen har en stor betydelse för effektiviteten, minskning av väntetider och ökad användningsgrad. Det är viktigt att bokningsprocessen är flexibel för att öka effektiviteten. Som resultat av denna rapport är slutsatsen att ett benchmarkning-projekt kan utföras på svenska radiologiavdelningar för att hitta bra arbetssätt.

Abstract:
AbstractThe research spans several application areas, including biotechnology, medical imaging, and environmental monitoring. Precise and specialized processing techniques are often required for measurements of signal parameters with high efficiency, for example, in terms of resolution and count rate, such as time of occurrence of events. Digital solutions have thus received the most significant attention since they are the most effective at enabling flexible, application-oriented elaboration systems. The research is finalized to develop high-resolution time measurement systems in Field Programmable Gate Array (FPGA) devices. The goal is to optimize resolution, linearity, and processing speed at the state-of-the-art in modern, most dynamic branches of very high-efficiency time measurement. To maximize the number of events handled in real-time, the research is also concentrated on developing cutting-edge communication and data transfer methods for performing multiple measures in parallel.

Abstract:
AbstractKeloids and hypertrophic scars are abnormal scars, produced by an odd wound-healing response to trauma with a higher incidence in pigmented skin patients. They could be painful or itchy, producing functional and/or cosmetic disability. This chapter focuses on defining scars especially in pigmented skin and the different methods for treating keloids that have been investigated in the literature. Up to the present time, the ideal treatment method has not been defined, although numerous modalities have been designated. We will represent the variances among different scar types and their management methods, concentrating on their indications, modes of action, uses, safety, and efficiency of the following therapies: intralesional steroid, injections of silicone gel/sheet, radiotherapy, photodynamic therapy, electrical stimulation, surgical excision and adjuvant therapy, and cryosurgery. Combination therapies have also shown some value. Still, there is a shortage of randomized clinical trials (RCTs) evaluating such treatment modalities. Management of scar in pigmented (colored) skin is clinically challenging. Therefore, strategic assessment and targeted therapy with focus on deterring recurrence are most needed. The quality of evidence is crucial to select efficient treatments for patients with colored skin, presenting with keloid.

Abstract:
AbstractIndustry has undertaken mass production and consumed resources to optimize only economic efficiency. Most products are discarded or disposed at the end of their lifetimes. Therefore, most companies should design and manage their production system for sustainability. One of the most important factors to develop a sustainable production system is the environmental aspect. Environmentally conscious operations management makes some contributions to sustainable development goals (SDGs) #9 and #12. This chapter deals with production and quality management systems for SDGs. Firstly, representative operations management systems such as inventory management and total quality management (TQM) are introduced. These systems are useful to control the production processes efficiently. Secondly, we explain the Just-in-Time (JIT) production system which is based on the two key concepts, JIT and JIDOKA. Some advantages of the JIT production system include its simplicity in production scheduling, reduced burden on operators, ease of identification of parts by the two kinds of kanbans attached to the containers, and substantial reduction in the process work. Finally, we consider environmentally conscious manufacturing and describe a closed loop supply chain which includes activities necessary to acquire end-of-life products from customers to recover value.

Abstract:
COVID-19 disclosed how public institutions efficiency is important. Governance, administration and management support state efficiency. Management cares to operationalise legal framework and policy measures. In EU environment, in industry 4.0, the system management and performance management are first among specific kinds of managing activities that support policy action. System management is not leaving anything coincidently. It builds the whole system of areas of elements in advance. Performance management is carefully programming targets and results. As there is a lot to rethink, how and in which way to survive and to develop, people expect that policy brings impact and result. At the same time, it is expected that management is efficient and mature. That it develops in a mature way technical details when preparing decisions, measures and their evaluation. This paper analyses data obtained in a survey, how management maturity is seen and comparing maturity of public managemet and management in private sector.

Abstract:
The exploration and production of polar oil and gas fields, which are technologically challenging due to extreme weather conditions, are also constrained by strong environmental issues. Safe and economical activities in such hostile and fragile regions require very insightful engineering. The presence of sea ice is representing a triple challenge: economical, technological and environmental. This makes the Arctic exploration and production activities complex. Ice Management (IM) is one of the tools that could efficiently assist to develop Arctic reserves. However, for each project that uses IM operations, a preliminary study is required to evaluate the efficiency of these support operations and to estimate the possible extension in the season of operation of a field. Efficiency of an IM philosophy can be estimated in a global view based on the extension in the operability window. In a more detailed view, it can be assessed taking into account the optimal number of icebreakers, the IM patterns, the available time for eventual disconnection, and the floe size reduction (leading to ice load reduction). For this study, we will focus on the ice floe size and loads reduction. The most common approach for physical management of sea ice is the one where icebreakers reduce floe size of the drifting ice upstream the floating platform (ref. Moran et al. [1], Coche et al. [2]). This paper describes this philosophy and demonstrates based on real-time simulation that its benefit is limited to mild ice scenarios such as unidirectional ice drift. A more efficient way to manage sea ice is (1) to identify the most hazardous events (e.g. big ridges); (2) prioritize these events; and (3) deal with them starting by the most hazardous one.

Full text
Abstract:
Drip irrigation has the potential of high water use efficiency, but actual water measurement is difficult because of the limited wetted volume. Two long-term experiments in orchards in Israel and in California and several field crop studies supported by this project have demonstrated the feasibility of precise monitoring of soil water distribution for drip irrigation in spite of the limited soil wetting. Time Domain Reflectometry (TDR) enables in situ measurement of soil water content of well defined small volumes. Several approaches were tried in monitoring the soil water balance in the field during drip irrigation. These also facilitated the estimation of water uptake: 1. The use of multilevel moisture probe TDR system. This approach proved to be of limited value because of the extremely small diameter of measurement. 2. The placement of 20 cm long TDR probes at predetermined distances from the drippers in citrus orchards. 3. Heavy instrumentation with neutron scattering access tubes and tensiometers of a single drip irrigated almond tree. 4. High resolution spatial and temporal measurements (0.1m x 0.1m grid) of water content by TDR in corn irrigated by surface and subsurface drip. The latter approach was accompanied by parametric modelling of water uptake intensity patterns by corn roots and superimposed with analytical solutions for water flow from point and line sources. All this lead to general and physically based suggestions for the placement of soil water sensors for scheduling drip irrigation.

Abstract:
As they increasingly adopt digital infrastructure, public administrations worldwide are increasingly collecting, generating and managing data. Empirical researchers are, at the same time, collaborating more and more with administrations, accessing vast amounts of data, and setting new research agendas. These collaborations have taken place in low-income countries in particular, where administrative data can be a valuable substitute for scarce survey data. However, the transition to a full-fledged digital administration can be a long and difficult process, sharply contrasting the common leap-frog narrative. Based on observations made during a five-year research collaboration with the Senegalese tax administration, this qualitative case study discusses the main data management challenges the tax administration faces. Much progress has recently been made with the modernisation of the administration’s digital capacity ,and adoption of e-filling and e-payment systems. However, there remains substantial scope for the administration to enhance data management and improve its efficiency in performing basic tasks, such as the identification of active taxpayers or the detection of various forms of non-compliance. In particular, there needs to be sustained investment in human resources specifically trained in data analysis. Recently progress has been made through creating – in collaboration with the researchers – a ‘datalab’ that now works to improve processes to collect, clean, merge and use data to improve revenue mobilisation.

Abstract:
The Inter-American Development Bank (IDB) was founded in 1959 as an initiative of Latin American and Caribbean (LAC) countries and the United States to support the development of the region through an institution in which LAC countries would play a leading role through their majority capital and voting shares but with significant participation of the United States. The Agreement Establishing the Inter-American Development Bank (the Agreement; IDB 1959/1996) articulated the desired balance of responsibilities and power between LAC and the United States. It also provided that the IDB's governance would center around three governing bodies: the Board of Governors (BOG), the Board of Executive Directors (EXD), and Senior Management. The objective of this evaluation, requested by the EXD, was to assess the extent to which existing institutional arrangements at the IDB allow it to operate effectively and efficiently while providing sufficient accountability, transparency, and stakeholder voice in decision making. The evaluation focused on four dimensions: (1) effectiveness--the extent to which the IDB's governance arrangements allow the institution to effectively set strategic objectives, provide means to attain those objectives, and monitor performance; (2) efficiency--the degree to which the costs (in both money and time) of the IDB's governing bodies to perform their assigned roles and responsibilities are consistent with their priorities; (3) accountability and transparency--the extent to which the IDB's governance arrangements render the IDB governing bodies accountable to its shareholders for the responsibilities delegated to them, and the ability of secondary stakeholders, such as civil society, project beneficiaries, and private sector entities, to access information; and (4) voice--the extent to which the IDB's governance arrangements provide the shareholders and secondary stakeholders with an adequate voice in decision making.

The article reveals the features of the state mechanism for regulating labor migration in the Jewish Autonomous Region. It is noted that labor migration is an integral part of the economic development of the region. The purpose of the study is the peculiarities of solving the problems of optimizing the mechanisms for regulating labor migration in the Jewish Autonomous Region (JAO). The practical significance of the study is underscored by the growing resource requirements of the Jewish Autonomous Region. The importance of attracting labor migrants from the widest list of countries, to increase the exchange of experience and improve interethnic relations, the organization of programs to increase the flow of willing workers and promising employers, is highlighted. The scientific novelty of the research is in the designation of the latest methods and state programs aimed at improving the efficiency of the labor migration management mechanism. Every year, the number of migrants illegally staying on the territory of Russia is growing, and the authorities of the Russian Federation are trying to improve the methods of control of foreign citizens entering the country, which makes it easier, but at the same time more effective, to exercise control over migrants and distribute it in. areas such as the patent system, employee-to-employer linkage and simplified taxation.

Abstract:
During the lockdown imposed due to the first wave of the coronavirus disease (COVID-19) pandemic, there were several media reports of citizens flouting the lockdown rules in the United States. Upon closer investigation it was found that the rules were flouted mostly so that people could spend time outdoors in natural environments. This exemplifies the role of the natural environment as a panacea to the mental stress created by pandemics. River ecosystems are perhaps the greatest natural feature of any city. Efficient management of urban rivers, therefore, is strongly correlated to crisis management during pandemics like COVID-19.

Full text
Abstract:
Training and professional development of nuclear power plant personnel are essential components of the atomic energy industry’s successful performance. The rapid growth of virtual reality (VR) and augmented reality (AR) technologies allowed to expand their scope and caused the need for various studies and experiments in terms of their application and effectiveness. Therefore, this publication studies the peculiarities of the application of VR and AR technologies for the training and professional development of personnel of nuclear power plants. The research and experiments on various aspects of VR and AR applications for specialists’ training in multiple fields have recently started. The analysis of international experience regarding the technologies application has shown that powerful companies and large companies have long used VR and AR in the industries they function. The paper analyzes the examples and trends of the application of VR technologies for nuclear power plants. It is determined that VR and AR’s economic efficiency for atomic power plants is achieved by eliminating design errors before starting the construction phase; reducing the cost and time expenditures for staff travel and staff training; increasing industrial safety, and increasing management efficiency. VR and AR technologies for nuclear power plants are successfully used in the following areas: modeling various atomic energy processes; construction of nuclear power plants; staff training and development; operation, repair, and maintenance of nuclear power plant equipment; presentation of activities and equipment. Peculiarities of application of VR and AR technologies for training of future specialists and advanced training of nuclear power plant personnel are analyzed. Staff training and professional development using VR and AR technologies take place in close to real-world conditions that are safe for participants and equipment. Applying VR and AR at nuclear power plants can increase efficiency: to work out the order of actions in the emergency mode; to optimize the temporary cost of urgent repairs; to test of dismantling/installation of elements of the equipment; to identify weaknesses in the work of individual pieces of equipment and the working complex as a whole. The trends in the application of VR and AR technologies for the popularization of professions in nuclear energy among children and youth are outlined. Due to VR and AR technologies, the issues of “nuclear energy safety” have gained new importance both for the personnel of nuclear power plants and for the training of future specialists in the energy sector. Using VR and AR to acquaint children and young people with atomic energy in a playful way, it becomes possible to inform about the peculiarities of the nuclear industry’s functioning and increase industry professions’ prestige.

Full text
Abstract:
Preferential flow is the process whereby water and solutes move by preferred pathways. During preferential flow, local wetting fronts propagate to considerable depths in the soil profile, essentially bypassing the matrix pore space. Under such conditions classical methods, such as the convective-dispersive equation, for quantifying flow of water and solutes in uniform soils are not valid. This project set out to develop methods to predict fast and early breakthrough of solutes. To facilitate understanding of these processes, several field drainage studies were conducted in the United States and Israel. In both countries, solutes moved rapidly down and could be found below 1 m depth soon after application. Based on these experiments, we developed and validated a number of modules to predict the solute concentration of the preferentially moving water in the vadose zone. We also successfully simulatd the initial high solute concentration in agriculturel tile lines shortly after the chemical was applied. The understanding gained on fast transport of agri-chemicals is instrumental in developing management practices to reduce the nonpoint sources and to increase the leaching efficiency of salt affected soils.

Full text
Abstract:
Central problems in sheep and dairy cattle production are reproductive failure due to embryonic/fetal mortality and low birth weights, especially in prolific breeds, and reduced milk yields which adversely affect neonatal survival and economy of production. The sheep placenta expresses lactogenic (ovine placental lactogen, oPL) and somatogenic (ovine placental growth hormone, oGH) hormones. Our research has focused on the biological roles of oPL and oGH in function of the uterine endometrium during gestation and the mammary gland during pregnancy and lactation. Major conclusions were that: ( 1 ) immunization of prepubertal ewes against oPL resulted in increased birth weights of their lambs and their milk production during lactation; (2) neither oPL nor oGH had an antiluteolytic effect on uterine endometrium to affect lifespan of the corpus luteum; (3) only sequential exposure of the progesterone stimulated uterus to oIFNt and oPL or oGH increased endometrial gland proliferation and secretory protein gene expression; (4) oPL signals through a homodimer of ovine prolactin receptor (PRL-R) and heterodimer of oPRL-R and growth hormone receptor (GH-R); (5) exogenous recombinant oPL and oGH stimulated mammogenesis and milk yield during lactation; and (6) mutation of oPL and oGH was used to define specific biological effects and a rational basis for design of a specific receptor agonists or antagonists. This project was very productive in elucidating basic biological effects of oPL and oGH on intracellular signal transduction pathways, uterine development and secretory function, as well as mammogenesis and lactogenesis. We determined that immunization of prepubertal ewes against roPL increased birth weights of their lambs, especially those born as twins and triplets, as well as enhanced lactational performance. These studies significantly extended our knowledge of uterine and fetal-placental physiology and provided a foundation for new strategies to enhance reproductive and lactation efficiency. Based on these results, the major achievements were: 1) creation of a practical and cost effective management tool for producers to increase reproductive performance, neonatal survival, and milk yield of ewes in commercial flocks; and 2) define, for the first time, biological effects of oPL on endometrial functions and gene expression by uterine gland epithelium.

Abstract:
The authors of the given article continue the series presented by the 2018 paper “Computer Simulation of Neural Networks Using Spreadsheets: The Dawn of the Age of Camelot”. This time, they consider mathematical informatics as the basis of higher engineering education fundamentalization. Mathematical informatics deals with smart simulation, information security, long-term data storage and big data management, artificial intelligence systems, etc. The authors suggest studying basic principles of mathematical informatics by applying cloud-oriented means of various levels including those traditionally considered supplementary – spreadsheets. The article considers ways of building neural network models in cloud-oriented spreadsheets, Google Sheets. The model is based on the problem of classifying multi-dimensional data provided in “The Use of Multiple Measurements in Taxonomic Problems” by R. A. Fisher. Edgar Anderson’s role in collecting and preparing the data in the 1920s-1930s is discussed as well as some peculiarities of data selection. There are presented data on the method of multi-dimensional data presentation in the form of an ideograph developed by Anderson and considered one of the first efficient ways of data visualization.
