Radio Planning

Transitioning a Terrestrial Trunked Radio (TETRA) network to a Long-Term Evolution (LTE) network in public protection and disaster relief (PPDR) systems is a path to providing future services requiring high radio interface throughput and allowing broadband PPDR (BB-PPDR) radio communications. Users of TETRA networks are currently considering how to deploy a BB-PPDR network in the coming years. This study offers several radio planning considerations in TETRA to LTE migration for such networks. The conclusions are obtained from a case study in which both measurements and radioelectric coverage simulations were carried out for the real scenario of the Murcia Region, Spain, for both TETRA and LTE systems. The proposed considerations can help PPDR agencies efficiently estimate the cost of converting a TETRA network to an LTE network. Uniquely in this study, the total area is divided into geographical areas of interest that are defined as administrative divisions (region, municipal areas, etc.). The analysis was carried out using a radio planning tool based on a geographic information system and the measurements have been used to tune the propagation models. According to the real scenario considered, the number of sites needed in the LTE network—for a specific quality of service (90% for the whole region and 85% for municipal areas)—is a factor of 2.4 higher than for TETRA network.

Floor Heating

The paper is oriented on the indoor environment influenced by radiant effect of floor heating. Questionnaire survey has showed problems with providing quality of indoor climate in new office building in Bratislava. The cause of problems was formation of local thermal discomfort, in particular mainly radiant asymmetry. To clarify the radiant asymmetry, there were carried out experimental measurements with thermal manikin in a special microclimatic laboratory for the radiant floor heating. The scientific analysis and the outputs from measurements are presented in this paper. In the conclusion of this paper are introduced principals for designing the offices’ interiors without local thermal discomfort.

Overall Evaluation

To facilitate the decision‐making and communication, an evaluation method has been devised that incorporates environmental effects of the energy use with thermal and atmospheric indoor climate in a score on an absolute scale from 0–100 %, called the “Eco‐factor”. This factor is based on indicators of physical properties. For the indoor climate part these include mainly the indoor temperature, velocity, and concentration fields. The energy part considers the energy distributed to energy sources, and the environmental effects of the resulting airborne emissions evaluated by Life Cycle Assessment (given by default figures from a database). The tool is used to make an overall assessment of the quality of design alternatives, where the “costs” (energy) is compared to the “benefit” (indoor climate), and to identify possibilities for improvement. The paper shows a model case study of an office building, where choices are considered that must be made in an early design phase.

<p>In the current economic climate museums are increasingly being asked to do more with less. For museums that hold collections, this poses a unique challenge. With the cost of collections being relentlessly accumulative, questions are being raised about the long term financial sustainability of current collecting practices. Deaccessioning is being suggested as a way in which museums can improve the quality of their collection without increasing its size. Yet the literature on deaccessioning suggests that the process is fraught with ethical and practical difficulties. By highlighting the negatives aspects of the process, writing in museum studies and practice does little to explore how deaccessioning might be used to achieve positive outcomes. This research addresses this gap by asking whether deaccessioning is a positive tool that, if used appropriately, can assist a museum in improving the quality and manageability of their collection through systematic planning. To understand how and why a museum may permanently remove objects from their collection, the study focuses on one New Zealand museum’s response to the challenge of redeveloping a collection through the process of deaccessioning and disposal. The Museum of Wellington City and Sea’s deaccessioning process is analysed through documentary research and interviews with Museum staff. The interviews offer an understanding of the thought processes and motivations involved in selecting objects to be deaccessioned. The data collected reveals both the challenging aspects of the process but also offers insights into how these aspects can be mitigated or resolved. The conclusions presented in this dissertation suggest that deaccessioning is an integral part of current museum practice that can be used positively to actively shape and refine a museum collection. I argue that some of the beneficial outcomes of the process include greater understanding of collections, improved knowledge and context, resolution of historical collecting problems, strategic relationships built with other museums and improvement in how objects are stored and utilised. More importantly deaccessioning allows museums to determine the character and content of their collections. In order for this to be achieved, I recommend that museums adopt a rational approach to reviewing their collections that is multi-disciplinary, transparent and acknowledges how their collection is used in the achievement of their institution’s mission.</p>

Community Centre

This case study aims at comprehensively assessing a decision by XYZ Ltd (name withheld due to confidentiality), New Delhi, on whether to build or to lease a recreation centre for its rank-and-file employees. Based on a cost–benefit analysis, we concluded that the centre should be built since the company would recover its investment within 11 years. Apart from the financial considerations, the recreation centre could be considered a long-term investment in employee morale, as it would lead to a better quality of life for the staff and their families, and is likely to enhance their sense of belonging and improve productivity. To date, what little space there is available for hosting family functions is reserved for the use of the officers, and only officers and their families are invited to most company functions. Thus, the other employees feel neglected by the management. Hiring a community centre external to the organisation for a function would involve spending a lot of money as the company is located in a prime real estate area where the cost of land and rentals is huge, and sometimes even availability is an issue. Most of the staff cannot afford such places and are generally under a lot of stress whenever they have a family function. This, in turn, tends to affect their productivity.

Medical staff shortages in the UK have provided impetus for the introduction of advanced clinical practitioners (ACPs). This case study explored the views of 22 ACPs, managers and doctors in primary and acute settings in a region of England, to understand how the role is used, and barriers and facilitators to its success. ACP roles improved the quality of service provision, provided clinical career development and enhanced job satisfaction for staff and required autonomous clinical decision-making, with a high degree of self-awareness and individual accountability. Barriers included disparate pay-scales and funding, difficulty accessing continuing education and research, and lack of agreed role definition and title, due to a lack of standardised regulation and governance, and organisational barriers, including limited access to referral systems. Facilitators were supportive colleagues and opportunities for peer networking. Regulation of ACP roles is urgently needed, along with evaluation of the cost-effectiveness and patient experience of such roles.

Aim:Aim: The purpose of this paper is to identify common mistakes and pitfalls as well as best practices in estimating labor intensity in software projects. The quality of estimations in less experienced teams is often unsatisfactory, as a result of which estimation as part of the software development process is abandoned. The decision is usually justified by misunderstanding "agility". This article is part of the discussion on current trends in estimation, especially in the context of the new "no estimates" approach.Design / Research methods: The publication is a case study based on the experience of a mature development team. The author, on the basis of literature-based estimation techniques, shows good and bad practices, as well as common mistakes in thinking and behavior.Conclusions / findings: The key to correct estimation is: understanding the difference between labor intensity and time, ability to monitor performance, as well as how to analyze staff requirements for the team.Originality / value of the article: The publication helps to master confidence-boosting techniques for any estimation (duration, and indirectly, the cost of software development) where requirements are known, but mainly at the stage of project implementation (design and implementation).Limitations of the research: The work does not address the problems of initial estimation of projects, i.e. the estimation made in the early stages of planning.

Distributed Test

Product-line architectures (PLAs) are a paradigm for developing software families by customizing and composing reusable artifacts, rather than handcrafting software from scratch. Extensive testing is required to develop reliable PLAs, which may have scores of valid variants that can be constructed from the architecture’s components. It is crucial that each variant be tested thoroughly to assure the quality of these applications on multiple platforms and hardware configurations. It is tedious and error-prone, however, to setup numerous distributed test environments manually and ensure they are deployed and configured correctly. To simplify and automate this process, the authors present a model-driven architecture (MDA) technique that can be used to (1) model a PLA’s configuration space, (2) automatically derive configurations to test, and (3) automate the packaging, deployment, and testing of con-figurations. To validate this MDA process, the authors use a distributed constraint optimization system case study to quantify the cost savings of using an MDA approach for the deployment and testing of PLAs.

The Cost

In the aftermath of the 1995 Kobe Earthquake, a large-scale effort towards reconstruction of houses damaged by the quake was required. This led to increased mortgage, thereby financially plaguing a number of earthquake victims and inhibiting their long-term sustainability and self-supported recovery. The current framework of housing reconstruction assistance provided by the Japanese government does not account for regional disparities in cost and other socioeconomic factors. This study proposes a technique for estimating the cost of reconstructing household units damaged in an earthquake by considering the effects of construction methods influenced by regional climatic zones. The financial constraints on rebuilding resources have been estimated by considering the annual regional income and household savings, as determined by social factors and employment opportunities. The susceptibility of regions to the occurrence of earthquakes has also been factored in the calculation of recovery costs. Together, these factors are used to provide a more complete picture of economic costs associated with earthquake recovery in different regions of Japan, thereby revealing large disparities in the difficulty and financial burden involved in the reconstruction of household units. Results of this study could be used to develop a robust system for earthquake-recovery assistance that accounts for differences in recovery costs between different regions, thereby improving the speed and quality of post-earthquake recovery.
