Objective: The aim of this activity was to develop an appropriate scale to accurately assess the level of clinical load carried by each case manager at the Royal Brisbane Hospital Integrated Mental Health Service. Method: A survey of, and consultation with, case managers over a period of 15 months was used to gather data and modify the monitoring tool for future use in the service. Results and Conclusion: Analysis of the data gathered revealed the level of case managers' work load burden and the depth of need required by clients. Professionally the Clinical Load Monitoring scores have been used in the allocation of additional cases for case management and in the supervision by discipline seniors. Service management has used the Clinical Load Monitoring Scale by dividing individual caseloads into low, medium and heavy service users – with low service users being further investigated for discharge from the service. Heavy service users were assessed for entry into more intensive treatment areas.

Full textAbstract:
The energy efficiency requirements of most energy-consuming sectors have increased recently in response to climate change. For buildings, this means targeting both facility managers and building users with the aim of identifying potential energy savings and encouraging more energy-responsible behaviors. The Information and Communication Technology (ICT) platform developed in Horizon 2020 FEEdBACk project intends to fulfill these goals by enabling the optimization of energy consumption, generation, and storage and control of flexible devices without compromising comfort levels and indoor air quality parameters. This work aims to demonstrate the real-world implementation and functionality of the ICT platform composed of Load Disaggregation, Net Load Forecast, Occupancy Forecast, Automation Manager, and Behavior Predictor applications. Particularly, the results obtained by individual applications during the test phase are presented alongside the specific metrics used to evaluate their performance.

AbstractProduction capacity is the amount of production with the determined assortment structure possible to achieve by a particular production unit in a determined time at the optimal use of production factors and at maintaining the products quality corresponding to standards. The objective of the paper was to determine the production power and output of particular workstations which constitute an assembly line of dry animal feed. The scope of research covered an assembly line in the establishment which produces dry feed for pet animals. Based on information and documentation obtained from the company manager and on the work schedule determined for particular workstations, the operation time of a machine, human work time (operation of a machine) and operation time of the entire station with its working surface was determined. Research showed that workstations which constituted the assembly line of dry animal feed were loaded within 76 to 86%. The lowest loading was reported in the mill and LP02 assembly line and it was respectively 76 and 78%. Whereas loading of the remaining devices was comparable and was at the level within 84 to 86%.

BackgroundA limited case-load size is considered crucial for some forms of intensive case management and many countries have undertaken extensive reorganisation of mental health services to achieve this. However, there has been limited empirical work to explore this specifically.AimsTo test whether there is a discrete threshold for changes in intensive case management practice determined by case-load size.Method‘Virtual’ case-load sizes were calculated for patients from their actual contacts over a 2-year period and were compared with the proportions of contacts devoted to medical and non-medical care (as a proxy for a more comprehensive service model).ResultsThere were 39 025 recordings for 545 patients over 2 years, with a mean rate of contacts per full-time case manager per month of 48 (range 35–60). There was no variation in the proportion of non-medical contacts when case-load sizes were over 1:20 but there was a convincing linear relationship when sizes were between 1:10 and 1:20.ConclusionsCase-load size between 1:10 and 1:20 does affect the practice of case management. However, there is no support for a paradigm shift in practice at a discrete level.

Full textAbstract:
Energy efficiency in buildings can be enhanced by several actions: encouraging users to comprehend and then adopt more energy-efficient behaviors; aiding building managers in maximizing energy savings; and using automation to optimize energy consumption, generation, and storage of controllable and flexible devices without compromising comfort levels and indoor air-quality parameters. This paper proposes an integrated Information and communications technology (ICT) based platform addressing all these factors. The gamification platform is embedded in the ICT platform along with an interactive energy management system, which aids interested stakeholders in optimizing “when and at which rate” energy should be buffered and consumed, with several advantages, such as reducing peak load, maximizing local renewable energy consumption, and delivering more efficient use of the resources available in individual buildings or blocks of buildings. This system also interacts with an automation manager and a users’ behavior predictor application. The work was developed in the Horizon 2020 FEEdBACk (Fostering Energy Efficiency and BehAvioral Change through ICT) project.

Full textAbstract:
A low input step-up DC/DC converter and power manager in 0.18-μm CMOS process is presented. The proposed converter can work with the input voltage as low as 20 mV. The extremely low input voltage makes it suitable for energy harvesting and power management. Four logic controlled outputs provide the best voltage for various applications to accommodate low power design requirements. A low current low dropout regulator (LDO) is utilized to provide a regulated 2.2 V output for powering low power processors or other low power integrated circuit (ICs). Reserve energy on the storage capacitor CSTORE provides power when the input voltage source is unavailable, thus prolongs the life of the system and expands the application range. Extremely low quiescent current (6 μA) and high efficiency design (64%@300 μA load current) ensure the fastest possible charge times of the output reservoir capacitor. This work provides a complete power management solution for wireless sensing and data acquisition.

Full textAbstract:
Emergency Call Alert (ECA) Application is developed for inform the urgency as well as seriousness of the call to the receiver. The profile in the mobile facilitates that the user to change the mode they need and this requires manual work load. This Call Manager changes the pro-file automatically to the desired mode designed by the user. It has also been enhanced with filtering mechanism called as Emergency calls filter which allows the calls from the emergency list to be in user preferred mode irrespective of the current mode. This feature is to avoid the missing of calls from the numbers specified in the emergency call list. Now a day most of calls come to us when we are busy, it is an interrupt, which disturbs or sometimes accident may happen. To avoid this either we switch off the mobile or we put the mobile in silent mode. If this is so if any emergency call comes we cannot attend such type of calls. The other disadvantage of this is the calling person does not know when the called person is free. To overcome all these problems we presented paper, Emergency Call Manager which handles all the call when he/she is busy sends an SMS. Software which filters this message and it gives an emergency alarm to called mobile.

Full textAbstract:
In Industrial Internet of Things (IoT) applications, when the network size increases and different types of flows share the bandwidth, the demand for flexible and efficient management of the communication network is compelling. In these scenarios, under varying workload and flow priorities, the combined use of Software-Defined Networking (SDN) and Network Virtualization (NV) is a promising solution, as such techniques allow to reduce the network management complexity. This work presents the PrioSDN Resource Manager (PrioSDN_RM), a resource management mechanism based on admission control for virtualized SDN-based networks. The proposed combination imposes bounds on the resource utilization for the virtual slices, which therefore share the network links, while maintaining isolation from each other. The presented approach exploits a priority-based runtime bandwidth distribution mechanism to dynamically react to load changes (e.g., due to alarms). The paper describes the design of the approach and provides experimental results obtained on a real testbed.

Load management of resources during high load demand managed by load management mechanism. An efficacious resource management algorithm effectively manages the load imbalance. Virtual Machine (VM) migration policy can maximize the throughput of the Cloud. Overloaded User Base (UB) high resource request increases the waiting time of the task and decreases the throughput. Task migration from high loaded VM to low loaded VM help to decrease the queue size and increase the throughput of the system. Effective resource management mechanism improves the performance and reduces the service level agreement (SLA) violations. Although researchers did the lot of work to manage load imbalance, but still need improvement. In this paper, proposed Dynamic weighted Live Migration (DWLM) Load balancing algorithm to manage the load imbalance problem. The proposed experiment result compares with another two algorithms. DWLM gives the better experiment results in Throughput, Migration time, Scalability and Fault Tolerance matrices.

199 Background: The Odette Cancer Centre (OCC) manages more than 24,000 chemotherapy visits annually. The delivery process is complex and patients have significant wait times for treatment. The OCC was faced with improving this process with no data infrastructure to support continuous quality improvement. Methods: An electronic scheduling manager, Chemotherapy Appointment Reservation Manager (CHARM) was built in house to improve scheduling logic and optimize bed and chair utilization. The chemotherapy unit has recently undergone renovations to change the staff-to-patient ratio and chair distribution. At baseline, a nurse is assigned to 4 chairs in a “pod” without adjustment for patient and chemotherapy intensity variation. An interprofessional team participated in a Kaizen event to create a Value Stream Map of the scheduling process. Scheduling logic considerations were identified to better match nursing and chair resources to patient appointment times. An analysis was performed to evaluate the distribution of patients throughout the chemotherapy unit by time of day, and day of week to identify opportunities to align the schedule with nursing and pharmacy resources. Results: The mean number of patients seen per day was 85 with a range of 65 to 105. 80% of patients are scheduled before 11:30 (the unit operations 08:30 to 18:00). The mean number of patients assigned to a pod was 8 with a range of 3 to 15. Unit performance on days of >95 patients was observed to be poorest. Load levelling techniques were established to reduce the range of patients booked per day throughout the week. New considerations for scheduling are: maximum 12 patients per nurse per pod per day, maximum 3 new patients per nurse per pod per day, maximum 10 clinical trials per day, and maximum 50% of patients scheduled before 11:30 per day. Conclusions: Matching the patient schedule to the nursing and pharmacy resources of the unit is critical to efficient and safe chemotherapy delivery. A Plan-Do-Study-Act is scheduled for September 2013 to implement the scheduling changes and evaluate the impact of the new logic on unit operations. Further work to improve the delivery process and pharmacy medication processing is ongoing.

Full textAbstract:
Users of wide area network applications are usually concerned about both response time and content validity. The common solution of client-side caching that reuses cached content based on arbitrary time-to-live may not be applicable in narrow bandwidth environment, where heavy load is imposed on sparse transmission abilities. In such cases, some users may wait for a long time for fresh content extracted from the origin server although they would settle for obsolescent content, while other users may receive the cached copy which is considered valid, although they would be ready to wait longer for fresher content. In this work, a new model for caching is introduced, where clients introduce preferences regarding their expectations for the time they are willing to wait, and the level of obsolescence they are willing to tolerate. The cache manager considers user preferences, and is capable of balancing the relative importance of each dimension. A cost model is used to determine which of the following three alternatives is most promising: delivery of a local cached copy, delivery of a copy from a cooperating cache, or delivery of a fresh copy from the origin server. The proposed model is proven to be useful by experiments that used both synthetic data and real Web traces simulation. The experiments reveal that using the proposed model, it becomes possible to meet client needs with reduced latency. We also show the benefit of cache cooperation in increasing hit ratios and reducing latency. A prototype of the proposed model was built and deployed on real-world environment demonstrating how users can set preferences towards Web pages, and how cache managers are affected.

Over the last few years, optimization models for the energy-efficient operation of railway traffic have received more and more attention, particularly in connection with timetable design. In this work, we study the effect of load management via timetabling. The idea is to consider trains as time-flexible consumers in the railway power supply network and to use slight shifts in the departure times from the stations to avoid too many simultaneous departures. This limits peak consumption and can help to improve the stability of the power supply. To this end, we derive efficient formulations for the problem of an optimal timetable adjustment based on a given timetable draft, two of which even allow for totally unimodular polyhedral descriptions. The proper choice of the objective function allows the incorporation of the priorities of either the train operating companies or the infrastructure manager. These include the avoidance of large peaks in average or instantaneous consumption and the improved use of recuperated braking energy. To solve the arising optimization models efficiently, we develop specially tailored exact Benders decomposition schemes that allow for the computation of high-quality solutions within a very short time. In an extensive case study for German railway passenger traffic, we show that our methods are capable of solving the problem on a nationwide scale. We see that the optimal adjustment of timetables entails a tremendous potential for reducing energy consumption.

Full textAbstract:
Gas lift is one of the most popular ways to increase oil-well production, and it is no secret that it is an underperformer. Back in 2014, ExxonMobil reported that by creating a team of roving gas-lift experts it was able to add an average of 22% more output on several hundred wells where the gas injection had been optimized. Gains were expected because “wells do not remain the same over time; they change,” said Rodney Bane, global artificial-lift manager at ExxonMobil, in this JPT story covering the 2014 SPE Artificial Lift Conference and Exhibition (https://jpt.spe.org/paying-close-attention-gas-lift-system-can-be-rewarding). The problem with gas injection is that change is hard. Injection adjustment or repairs require either pulling the tubing to reach the injection mandrels or a wireline run. Those with good- producing wells, particularly offshore, need to weigh the possible gain against the cost and lost production during the job. Those managing more and more wells live with iffy data, injection systems prone to malfunction, horizontal wells prone to irregular flows, and a time-consuming process for calculating the proper injection rates. New approaches addressing those negatives have led a few big operators to try new systems designed to allow constant adjustments based on downhole data with electric control systems designed to be more reliable. Programmable digital controls raise an obvious question: How do you take advantage of that capability? Constantly updated injection data based on traditional evaluation methods is the first step. And new capabilities are inspiring new thinking about how injected gas lifts production and how to make it work more efficiently. Optimizing the process has not been a priority in gas lift. “It was a fairly imprecise thing. But the beauty of gas lift is it works even where it’s broken. It’s not a pump; it’s flow assurance,” said Brent Vangolen, surface and base management technology manager with Occidental. Occidental is among the early adopters of new gas-lift methods along with companies including Chevron, Shell, ExxonMobil, Petronas, and ADNOC. Vangolen expects the industry will follow. “Gas lift is going through the same transformation as rod pumps went through in the 60s and 70s,” he said. Back then, rod pump engineers began tracking changes in the load on the rod through each pump stroke by using dynamometer cards. That data was used to better program pump controls. “You went from egg timers on pumping units to full-blown optimization pumpoff controllers, variable speed drives … this huge infant technology that changed the rod pump space,” he said. Papers at last year’s SPE artificial lift conference covered the continuing digitization in rod lift and that gas lift was finally moving in that direction.

Actions of the functional leader in the selection of the team of executors of the scientific project. Specificity of scientific tasks in the military field is the need to overcome the uncertainties caused by the unpredictability of the enemy during combat. The complexity and multidimensionality of the problem of planning and managing the scientific and technical activities in the security and defense sector necessitate the improvement of existing planning and management mechanisms in the Armed Forces of Ukraine. Management activities of functional leaders is one of the important factors for the success and quality of scientific tasks. In the teaching and research processes of higher military education there is a wide range of management entities. The content and scope of managerial functions of heads of departments, faculties and departments are defined in the relevant charters, guidelines and instructions. However, it is very difficult to identify the quantitative weight of each institution of management of the scientific-pedagogical system of higher education institutions and its structural units. The order of performing management functions during certain periods of activity is worked out by each entity, mainly independently, on the basis of personal experience, the choice of forms, methods and means of influencing the management object is, for the most part, a creative process. One of the important aspects of the implementation of a scientific project that depends on the end result is the selection of the "right" team of project executors and the project resource, namely: specialists in the field of research, motivated by the result, able to achieve it by their competence, not overloaded with other work , plus - comprehensive security of the project. In order to increase the effectiveness of management activities, to apply the management of the institution (the chief and his deputy for scientific work) by the apparatus, to qualitatively evaluate and make the right management decisions at the stage of appointment of the project manager and the team of executors of the scientific project, to determine the resource base and limitations in this particular scientific project, this technique is proposed. Management of scientific projects in all phases of their implementation - from order to implementation, is a priority direction of increasing the efficiency of the system of scientific and scientific-technical activity of the Armed Forces of Ukraine. The implementation of the algorithm of selection of the team of executors of the scientific project is an effective mechanism for optimizing the decision-making process by functional managers in the early stages of scientific projects.

Purpose – The purpose of this paper is to identify the determinants of perceived work-related stress among public sector managers. Design/methodology/approach – A general questionnaire-based survey of managers at all managerial levels in Danish organizations concerning the content of their job and the way it is practiced (n=1,500, response rate 72 per cent) are applied. For the purpose of this paper only specific information related to the perception of work stress among public sector managers is analyzed (n=400). Findings – The perception of stress are influenced by factors like gender, managerial level, work load, the influence on own job situation, if they have children living at home as well as the percentage of work-at-home. Research limitations/implications – In a general survey work stress is one among a larger number of issues. This fact may influence the validity of the information – in a positive as well as a negative way. However, the findings point to issues which call for more in-depth analyses. Practical implications – The identified significant determinants influencing the perception of stress point to issues where preventive initiatives can be taken. Social implications – Since work-related stress may cause absence from work it may influence production and the health system. If preventive measures can be taken a positive impact on the economy may be the result. Originality/value – Work-related stress has been studied before. But little focus has been given to the public sector and especially managers. Furthermore, including a variety of potential explanatory determinants such a work-life balance, psycho-social work characteristics, gender and managerial level – as well as the potential interaction between them – give a detailed platform for the analyses.

Abstract. Alongside other countries that are signatories to the UNECE Convention Long Range Transboundary on Air Pollution, the UK is committed to reducing the impact of air pollution on the environment. To advise and guide this policy in relation to atmospheric emissions of sulphur and nitrogen, a critical load approach has been developed. To assess the potential impact of these pollutants on woodland habitats a steady state, simple mass balance model has been parameterised. For mineral soils, a Ca:Al ratio in soil solution has been used as the critical load indicator for potential damage. For peat and organic soils critical loads have been set according to a pH criterion. Together these approaches have been used with national datasets to examine the potential scale of acidification in woodland habitats across the UK. The results can be mapped to show the spatial variability in critical loads of the three principal woodland habitat types (managed coniferous, managed broadleaved/ mixed woodland and unmanaged woodland). The results suggest that there is a wide range of critical loads. The most sensitive (lowest) critical loads are associated with managed coniferous followed by unmanaged woodland on peat soils. Calculations indicate that at steady state, acid deposition inputs reported for 1995–1997 result in a large proportion of all the woodland habitats identified receiving deposition loads in excess of their critical load; i.e. critical loads are exceeded. These are discussed in relation to future modelled depositions for 2010. Whilst significant widespread negative impacts of such deposition on UK woodland habitats have not been reported, the work serves to illustrate that if acid deposition inputs were maintained and projected emissions reductions not achieved, the long-term sustainability of large areas of woodland in the UK could be compromised.

In this literature, a new automated control strategy has been developed to manage the power supply from the wind power generation system to the load. The main objective of this research work is to develop a fuzzy logic–based pitch angle control and to develop a static transfer switch to make power balance between the wind power generation system and the loads. The power management control system is a progression of logic expressions, designed based on generating power and load power requirement. The outcome of this work targets at an improved power production, active and reactive power compensation and ensures system load constraints. To validate the proposed control strategy, a detailed simulation study is carried out on a 9-MW wind farm simulation simulated in MATLAB/Simulink environment.

The article is devoted to the practical component of the professional training of a social worker in a Polish high school. Conceptual approaches are considered in relation to professional preparation of development workers and experience actualized by them with practical preparation at higher school of Poland. It is found out, that preparation of development workers in Poland is a difficult and dynamic process, that permanently changes in accordance with international standards, normative requirements, social changes and necessities on this type of services. As a result of scientific research, the tendency to introduce professional training in the practice of Polish social workers on the progressive approaches of practical experience in the social sphere of European countries and the United States has been traced. It is noted that the model of structured learning is based on the use of a curriculum on a modular basis. Different teaching methods, especially simulation and activity (training in the "team") are used. Equally important is the acquisition of skills, and the assimilation of the value basis of the student's work. Assessment is based on the criteria of competence. The student works under the direct supervision and supervision of the practice leader. Emphasis is placed on the theory of practical learning through experience. According to the results of the study, the organizational and pedagogical conditions of the organization and content of practical training of social workers in practice in Poland are set out: legislative regulation of general principles of practice and internship in Polish universities; the removal of a significant part of the study load (from 40% to 60%) into the obligatory volume of the organization of students' practice directly at the workplace; continuity of the practical orientation of the educational process to practical learning through experience in practice; compliance of modules of practical training programs in practice under the Framework Program for the qualification of a social worker: knowledge, skills, social competences; the variability of the proposals for places of practice for students and the proposed contact letters at the information stands of the departments of social work (pedagogy); provision of means for checking the implementation of modules by trainees through the electronic network, depending on the form of training and the student's capabilities (stationary, correspondence, distance, etc.); providing support for practical training of future social workers in practice (contact hours, independent work, literature to silabases (programs) of practice, etc.); consistency of the procedure for managing and controlling individual programs of student practice from the university and social institution; Settlement of the appointment of students responsible for passing the practice: the coordinator (for bachelors, mainly masters), a mentor, a representative from the practice institution and the manager of the management of the career bureau. The study concluded that the practical component of the program for the training of future social workers in Ukraine should be based on familiarizing students with the European forms, methods and techniques of work, and also involving them in direct and continuous practical activities, under the guidance of experienced mentors and consultants. The exposure of progressive ideas of experience of practical aspect of preparation of development workers in Poland will assist the scientific ground of strategy of development of professional preparation of specialists of social sphere in Ukraine on the stage of her transformation and integration in European and world educational space. The prospects of research of directions of co-operation of establishments of education are certain with employers and other social partners in the process of professional preparation and passing of types of practices by the future specialists of social work.

This article describes a framework for load shedding techniques using dynamic pricing and multi-agent system. The islanded microgrid uses solar panels and battery energy management system as a source of energy to serve remote communities who have no access to the grid with a randomized type of power in terms of individual load. The generated framework includes modeling of solar panels, battery storage and loads to optimize the energy usage and reduce the electricity bills. In this work, the loads are classified as critical and non-critical. The agents are designed in a decentralized manner, which includes solar agent, storage agent and load agent. The load shedding experiment of the framework is mapped with the manual operation done at Kisiju village, Pwani, Tanzania. Experiment results show that the use of pricing factor as a demand response makes the microgrid sustainable as it manages to control and monitor its supply and demand, hence, the load being capable of shedding its own appliances when the power supplied is not enough.

A Home Energy Management (HEM) system is an integral part of a smart grid that can potentially enable demand response applications for residential customers. It provides a homeowner the ability to automatically perform smart load controls based on utility signals, customers preference and load priority. This paper presents an intelligent HEM for managing high power consumption household appliances for demand response (DR) analysis. The proposed HEM manages household loads according to their preset priority and guarantees the total household power consumption below certain levels.Given the lack of understanding about DR potentials in this market, this work serves as an essential stepping-stone toward providing an insight into how much DR can be performed for residential customers.

The continuous growth in wireless communication, the demand for sophisticated, simple and low-cost solutions are also increasing. The demand motivated the researchers to indulge into inventing suitable network solutions ranging from wireless sensor networks to wireless ad-hoc networks to Internet of Things (IoT). With the inventions coming from the researchers, the demand for further improvements into the existing researchers have also growth upbound. Initially the network protocols were the demand for research and further improvements. Nevertheless, the IoT devices are started getting used in various fields and started gathering a huge volume of data using complex application. This invites the demands for research on load balancing for IoT networks. Several research attempts were made to overcome the communication overheads caused by the heavy loads on the IoT networks. Theses research attempts proposed to manage the loads in the network by equally distributing the loads among the IoT nodes. Nonetheless, in the due course of time, the practitioners have decided to move the data collected by the IoT nodes and the applications processing those data in to the cloud. Hence, the challenge is to build an algorithm for cloud-based load balancer matching with the demands from the IoT network protocols. Hence, this work proposes a novel algorithm for managing the loads on cloud integrated IoT network frameworks. The proposed algorithm utilizes the analytics of loads on cloud computing environments driven by the physical host machines and the virtual environments. The major challenge addressed by this work is to design a load balancer considering the low availability of the energy and computational capabilities of IoT nodes but with the objective to improve the response time of the IoT network. The proposed algorithm for load balancer is designed considering the low effort integrations with existing IoT framework for making the wireless communication world a better place.

Full textAbstract:
Microfinance Institutions (MFIs), in addition to the provision of microcredit, also provide business development services (BDS) to owner managers in order to develop micro enterprises. BDS are non-financial services such as business training and access to information that help owner managers of microenterprises to develop businesses. In this respect, counsellors and trainers in MFIs co-produce BDS with owner managers. Co-production is the joint efforts of two parties, who together determine the output of their collaboration. The objective of this study therefore is to examine how co-production works in a BDS setting. A multiple case study method was used to carry out the study. Six MFIs were selected as cases and in-depth interviews were held with counsellors, trainers and managers to collect the data. The findings reveal that the expertise of counsellors, trainers and owner managers are the inputs for co-production. The outputs of co-production are twofold: MFI specific outputs and owner manager specific outputs. While MFI specific outputs are identified in better loan repayments rates, enhanced client satisfaction, and increased client retention, the owner manager specific outputs are denoted by better business knowledge, better sales, and profits. MFIs use counselling and training as modalities to co-produce BDS. There are a number of factors that affect the variability in coproduction including the readiness of counsellors and trainers, with a number of BDS provided under each modality. Therein, the findings of this study are beneficial to microfinance practitioners and policy makers. Furthermore, the findings also contribute to the knowledge domain of microfinance. Keywords: business development services (BDS), co-production, microfinance, case study method.

The study examines the impact of credit officers’ Quality of Work Life (QWL) on productivity of loan disbursement in 10 selected Savings and Loans Companies in the Accra, Ghana. The study was quantitative, cross-sectional, descriptive and analytical. Out of 1602 employees, 310 employees were sampled. Simple random sampling technique was used to select both companies and respondents. 92% of questionnaires were self-administered and 8% were e-mailed. The finding indicated a significant positive impact of credit officers’ QWL on productivity of loan disbursement (β= .274, p<.001).<strong> </strong>It was suggested that it will be profitable to and prudent on the part of managers not to play with the QWL of credit officers if they really want to experience an increase in loan disbursement. Also, managers’ comprehensive focus on the general happiness of credit officers by ensuring employees’ holistic well-being in the organisation will lead to productivity of loan disbursement. The study becomes the first to research on both credit officers and productivity of loan disbursement in the financial sector of Ghana.

An effective load balancing mechanism maximizes the throughput minimizes the response time with fault tolerance. Load imbalance problems occasionally occur during the over-demanding of resources from VMs. Load balance mechanisms manage the load by allocating jobs and reallocation of VMs. This article proposes the Dynamic Weighted Live Migration (DWLM) mechanism. DWLM mechanism based on LP-formulation-based heuristic approaches to dynamically manage load balancing. DWLM approaches use transfer, selection, and location polices. These policies work based on an information policy. The authors map the result in migration time, throughput, response time and fault tolerance. The proposed DWLM mechanism gives the best results from Equally Spared Current Execution (ESCEL) and Push-Pull mechanisms. A comparison table and associated charts show the efficiency of the proposed DWLM mechanism.

The varying solar irradiation effects and its intermittency have been successfully managed by the boost converter controlled by MPPT and supercapacitor controlled by bidirectional converter. The bidirectional converter step down and step up the terminal voltage and provides the power flow in a bidirectional manner. The proposed model helps in obtaining the seamless action under changing irradiation and for varying load conditions. The performance of the SMC controlled Inverter, when compared with a PI controlled Inverter, has been found to be superior in terms of power quality and robustness of the supply system.

This paper presents a comparison and assessment of usefulness of various measuring techniques (terrestrial laser scanning (TLS), tachymetry, photogrammetry) applied to establish the behavior of a suspension bridge under different load scenarios. The applied techniques were examined on the bridge with a 165 m span. The tested structure works as the technological bridge for a belt conveyor linking a lime mine and cement plant. The testing range consisted of conducting the non-contact measuring of the bridge and cable displacements under dynamic loads (during the belt conveyor movement—normal service loads) and static loads (while stopped). Tachymetric surveys were carried out using a precise total station (to obtain the reference data). A Canon 750D digital camera was applied in the photogrammetry technique. FARO Focus 3D and Trimble TX8 scanners were employed for the TLS measuring. The obtained results are especially important for bridge inspectors and managers who can use the non-contact measurements of serviced structures.

Smart grid (SG) vision has come to incorporate various communication technologies, which facilitate residential users to adopt different scheduling schemes in order to manage energy usage with reduced carbon emission. In this work, we have proposed a residential load management mechanism with the incorporation of energy resources (RESs) i.e., solar energy. For this purpose, a real-time electricity price (RTP), energy demand, user preferences and renewable energy parameters are taken as an inputs and genetic algorithm (GA) has been used to manage and schedule residential load with the objective of cost, user discomfort, and peak-to-average ratio (PAR) reduction. Initially, RTP is used to reduce the energy consumption cost. However, to minimize the cost along with reducing the peaks, a combined pricing model, i.e., RTP with inclining block rate (IBR) has been used which incorporates user preferences and RES to optimally schedule load demand. User comfort and cost reduction are contradictory objectives, and difficult to maximize, simultaneously. Considering this trade-off, a combined pricing scheme is modelled in such a way that users are given priority to achieve their objective as per their requirements. To validate and analyze the performance of the proposed algorithm, we first propose mathematical models of all utilized loads, and then multi-objective optimization problem has been formulated. Furthermore, analytical results regarding the objective function and the associated constraints have also been provided to validate simulation results. Simulation results demonstrate a significant reduction in the energy cost along with the achievement of both grid stability in terms of reduced peak and high comfort..

Background and Study Aim. The purpose of the study was to determine the peculiarities of using pattern recognition method in the management of the cumulative effect of strength loads in 8-year-old boys.
Materials and methods. The study participants were 48 boys aged 8. The experiment was conducted using a 22 factorial design. The study materials were processed by the IBM SPSS 22 statistical analysis program. Discriminant analysis was performed. The study examined the impact of four variants of strength load on the formation of the cumulative training effect of three, six, nine, and twelve classes in 8-year-old boys.
Results. The discriminant analysis provided information about the impact of four orthogonal variants of strength loads on the formation of the cumulative training effect of strength exercises of three, six, nine, and twelve classes in 8-year-old boys. The obtained data make it possible to choose a load mode at each step of the CTE formation and to manage schoolchildren’s strength training.
Conclusions. The verification of the obtained discriminant functions shows their high discriminative ability and value in interpretation with respect to the general population (p < 0.05). It was found that the formation of the CTE of three classes is most influenced by the third load variant, six classes – by the third load variant, nine classes – the third load variant, twelve classes – the first load variant. The discriminant function structure coefficients made it possible to identify the factor structure of the CTE of 3, 6, 9, 12 classes, to find that the CTE3, CTE6 are associated with the work at the first place “Exercises to strengthen arm muscles”, the CTE9, CTE12 – with the work at the third (“Exercises to strengthen back muscles”) and the fourth (“Exercises to strengthen leg muscles”) places. The CTE of three, six, nine, and twelve classes depends on the modes of strength exercises and has different focuses. The CTE3 – speed and strength focus; CTE6, 9 – comprehensive focus; CTE12 – explosive-strength focus. The obtained values of centroids for the CTE of 3, 6, 9, 12 classes enable the management of schoolchildren’s strength training.

Full textAbstract:
Working time studies, work productivity, and cost assessments of forest logging are of interest to forest managers and planners. These aspects are particularly important in salvage logging, because of difficulties due to irregularly positioned fallen trees in forest areas, and due to particular aspects related to the absence of work planning. In this research, system productivity and the cost of salvage logging are analyzed for two mountain forests managed with close-to nature-silviculture: the Hyrcanian forest, using extraction by a skidder, and the Camaldoli forest, using extraction by tractors. The system productivity of salvage logging by skidders and tractors was calculated as 1.54 and 0.81 m3·h−1, respectively. In contrast to common logging, system productivity was about 6- to 15-fold lower in salvage logging. The effective cost consumptions for the skidder and tractor were calculated as $72.57 and $118.62 USD·m−3, respectively. For both yards, winching time increased due to increasing winching distance and winching load volume. The same result was determined for skidding time in relation to load volume and distance. The possible cost decreases for the skidder and tractor were calculated as 2.6% and 4.3%, respectively. The results revealed that operational costs for extracting wind-fallen trees are higher than for traditional standing-trees extraction for both situations studied. In both cases, the harvesting costs were higher than the timber price by 10% to 30%. Therefore, extraction of wind-fallen trees has no economic justification in these forests.

The warehouse transport environment changes with load movement, e.g., the area where a load is placed becomes an obstacle for a carrier and the area from which a load is removed becomes area once more useable for movement. These considerations make path planning an important aspect of work planning. Transport system is suggested to manage environment change using radio frequency identification (RFID) which is put on a load and records the data of load size and its position. When the environment data of RFID changes by placing or removing the load, new information is read by reader of load carrier and sent to map management server. A three-omnidirectional vehicle is used to make transport more efficient.

After reduction of the external phosphorus load by phosphorus elimination plants, Lake Tegel and Schlachtensee in Berlin underwent a significant trophic improvement. The phosphorus elimination plants work by precipitation/coagulation/flocculation – sedimentation – post precipitation – filtration. The external load was reduced by one to two orders of magnitude down to 10–20 μg P L−1.The inlake phosphorus concentration followed. The development of algae and cyanobacteria was reduced substantially below a threshold value of about 50 μg P L−1, clearly due to phosphorus limitation. In Lake Tegel, the external load reduction of the main inflow was counteracted partially by the external load of the second main inflow by the River Havel and the internal load. This has to be managed further in future.

Full textAbstract:
This work describes an optimum utilization of hybrid photovoltaic (PV)—wind energy for residential buildings on its occurrence with a newly proposed autonomous fuzzy controller (AuFuCo). In this regard, a virtual model of a vertical axis wind turbine (VAWT) and PV system (each rated at 2 kW) are constructed in a MATLAB Simulink environment. An autonomous fuzzy inference system is applied to model primary units of the controller such as load forecasting (LF), grid power selection (GPS) switch, renewable energy management system (REMS), and fuzzy load switch (FLS). The residential load consumption pattern (4 kW of connected load) is allowed to consume energy from the grid and hybrid resources located at the demand side and classified as base, priority, short-term, and schedulable loads. The simulation results identify that the proposed controller manages the demand side management (DSM) techniques for peak load shifting and valley filling effectively with renewable sources. Also, energy costs and savings for the home environment are evaluated using the proposed controller. Further, the energy conservation technique is studied by increasing renewable conversion efficiency (18% to 23% for PV and 35% to 45% for the VAWT model), which reduces the spending of 0.5% in energy cost and a 1.25% reduction in grid demand for 24-time units/day of the simulation study. Additionally, the proposed controller is adapted for computing energy cost (considering the same load pattern) for future demand, and it is exposed that the PV-wind energy cost reduced to 6.9% but 30.6% increase of coal energy cost due to its rise in the Indian energy market by 2030.

This paper presents an h-infinity robust loop shaping control and LCL filter to mitigate the effects of harmonic currents in the photovoltaic system integrated with the grid. To eliminate the negative effects of the LCL filter, this work applied notch filter active damping. Existing methods for the elimination of harmonic currents were reviewed. Proportional integral control, fuzzy logic control, h-infinity control, and robust loop shaping control are presented. The grid current was analyzed in the system with all controllers applied to control the voltage source inverter of the system to eliminate harmonics in the grid current caused by the inverter and nonlinear loads for two cases, one being constant loading of the linear and nonlinear load and another is the switching of the nonlinear load during the simulation. The results obtained from the proposed method for the two tests conducted were compared with those from other methods to prove the robustness of the proposed technique. The method manages to reduce the total harmonic distortion of the grid current from 7.85% to 0.79% for case 1 and from 11.67% to 1.14% for case 2.

Full textAbstract:
Forecasting energy demand within a distribution network is essential for developing strategies to manage and optimize available energy resources and the associated infrastructure. In this study, we consider remote communities in the Arctic located at the end of the radial distribution network without alternative energy supply. Therefore, it is crucial to develop an accurate forecasting model to manage and optimize the limited energy resources available. We first compare the accuracy of several models that perform short-and medium-term load forecasts in rural areas, where a single industrial customer dominates the electricity consumption. We consider both statistical methods and machine learning models to predict energy demand. Then, we evaluate the transferability of each method to a geographical rural area different from the one considered for training. Our results indicate that statistical models achieve higher accuracy on longer forecast horizons relative to neural networks, while the machine-learning approaches perform better in predicting load at shorter time intervals. The machine learning models also exhibit good transferability, as they manage to predict well the load at new locations that were not accounted for during training. Our work will serve as a guide for selecting the appropriate prediction model and apply it to perform energy load forecasting in rural areas and in locations where historical consumption data may be limited or even not available.

Full textAbstract:
Software defined networking(SDN) is a technique in networking which provides the administrators of the network with access to initialize, control, manage, and dynamically change how the network behaves through open interfaces and by the lower-level functioning abstraction. SDN simply addresses the basic knowledge that the architecture being static in traditional networks never provides assistance for the dynamic or scalable computing along along with the storage requirements of most of the modern computing. This is possible by the methods of decoupling or disassociation of the system that helps in making decisions about where the traffic is being delivered from the systems which then forwards this traffic to the required destination. Load balancing is the method in a computer network that is used to divide the amount of work between a collaboration of two or more computers in such a way that work can be completed in the same time limit. Hardware, software, or a combination of both can be used to implement load balancing. Moreover, computer server clustering is caused due to load balancing.This paper discusses the various kinds of load balancing algorithms which can help in better utilisation of resources and linear service delivery across multiple clients in an SDN environment.

Full textAbstract:
Purpose The purpose of this paper is to answer the increasing calls to analyse how lending relationship between banks and their small- and medium-sized enterprises (SMEs) work. More precisely, the main aim is to investigate the lending approach(es) and criteria used by banks to assess loan applications from their relationship-managed (RM) SMEs’ clients. Other objectives include investigating the level of congruence in terms of lending practices and processes among the sample banks in New Zealand (NZ) and to discern how the assessment of the SME owner/manager is done within the relationship-banking framework. Design/methodology/approach The research objectives concern investigating processes and not variances. Thus, a qualitative research approach was used. Extensive data was collected via interviews across representative banks in NZ and thematic analysis was used to analyse the data. Findings The findings include a detailed analysis of how relationship banking actually works; how in NZ, the main bank brands use three criteria of lending (financials, security and character) as a framework of assessing loan applications from RM-clients – which is different from the character, capital, capacity, conditions, and collateral (5Cs) that are widely used and discussed as the framework of lending; and an elucidation as to why and how character assessment is different from the other criteria of lending. Originality/value To the best of authors’ knowledge, this is the first study to investigate the mechanisms and processes that banks use to deal with their RM-SMEs, show the existence of a different framework of lending other than the 5Cs and attempt an explanation as to why character evaluation is different from that of the other criteria of lending.
