A case study was conducted and combined with literature reviews to test this proposition. The results of this paper show that the formula appears dynamic on the impacts of economic depression/recession, inflation, and change of governmental policy to assist the firms in the achievement of planned profits. TC, as a strategic profit management system in the industry, exhibits brisk utilization in a dynamic formula with more of a focus on value added to maintain fixed profits. It is different from the focus on cost reduction by a static formula in previous literatures.展开更多

The original COCOMO model is one of the most widely practiced and popular among the software development community because of its flexible usage. It is a suite of models i.e., COnstructive Cost MOdel I and COnstructive Cost MOdel II. in this paper, we are evaluating the both models, to find out the level of efficiency they present and how they can be tailored to the needs of modem software development projects. We are applying COCOMO models on a case study of an e-commerce application that is built using Hyper Text Markup Language (HTML) and JavaScript. We will also shed light on the different components of each model, and how their Cost Drivers effect on the accuracy of cost estimations for software development projects.展开更多

The majority of these projects involve a new design with an enhanced level of safety, called GEN (Generation) III+. Although the serious events at the Japanese Fukushima Daiichi NPP caused by a tsunami led to a reduction in the number of new projects or even a phase out of nuclear power in some countries, only a slight reduction or delay of projects is expected globally. GEN III+ new build projects give rise to several economical, technical, human resource and organizational challenges. The paper starts with a discussion of these challenges and presents several activities that have been started to deal with them. It focuses on the development of human resources, coordinated approach of operators and suppliers can lead to the needs-oriented human resources development. particularly with operators and suppliers of GEN III+ NPPs.

We present two examples from the Thai component of the research program to show how different disciplines and stakeholders need to cooperate at different scales to make meaningful scientific contributions towards sustainable land use and rural development in mountainous regions. The case of resource conservation in the Thai highlands shows that local and scientific knowledge, conven- tional surveys and participatory modeling can be creatively combined. Integrated research on the potential of integrating fruit trees and associated technologies into mountain farming systems suggests that natural scientists have to work alongsideeconomists and social scientists to avoid harmful effects of purely technology-driven and productivity- enhancing approaches. The success of new technologies cannot be measured solely by adoption rates and yield increases, but also needs to take into account their long-term impact on various groups of farmers and the ecological, economic and social trade-offs that they entail. Technical and institutional innovations need to go hand in hand to provide viable livelihood opportunities for smallholder farmers in mountain watersheds. The major lesson learned from the first six years of our research in the mountains of Thailand and Vietnam is that conventional and participatory approaches are not antagonistic; if scientists from various disciplines and research paradigms are open-minded, the combination of both approaches can produce meaningful results that cater for the needs of both the academic community and local stakeholders in mountain environments.展开更多

Following this trend, architectural design may exploit the use of (eco) materials and components to promote a project as sustainable even without considering its impact on the environment; This can be defined as architectural greenwash. This paper considers the case of green envelopes with the aim to evaluate if these can be defined as sustainable design practice. Green envelopes provide environmental advantages together with the suggestion to a green aesthetics par excellence. In fact, the integration of vegetation in urban fabric plays an important role in improving ecological and environmental conditions of (and in) cities, although systems can have a high environmental burden. This paper aims to answer the question: Is greening the building envelope a sustainable design practice? To do so, the paper provides a literature review which includes the main research developed regarding environmental burden, benefits and LCA (life cycle assessment) calculations of green envelopes.展开更多

In France, the first issue released by the secular magazine Charlie Hebdo after the terrorist attack depicted a religious figure declaring, "All is forgiven." In each instance the boundaries between the "secular" and "religious" were transgressed. In the academic study of religion, an additional direction methodology needs to take involves the lens formed by academic concepts and categories as shaped by the historical development of the university's discourses and lines of inquiry. The university is an epistemological project and we look "out there" through concepts and categories formed "in here", inside of the history of "the university". It is another dimension to the problem of the insider/outsider. This paper will use the characteristics of interdisciplinarity to historicize how the university as an epistemological project has developed the concepts of "religion", the "secular", and the binary they form, in order to suggest directions for their use to interpret events in the 21 st century through the academic study of religion.展开更多

Participatory research based on Andean experiences pre-dated and inspired much of the later international movement in agriculture, health, and conservation. Andean communities have a long history in demanding that outsiders address the needs of the community as a condition for carrying out scientific or applied activities. What an Andean community, however, sees as relevant may or may not be within the rubric of ‘participatory research’ as it is practiced throughout much of the world. In fact, overzealous participatory researchers are just as bothersome as their predecessors bearing long questionnaires. More important to Andean people is an equitable relationship with researchers and developers in which exchanges of value are made. A distinction between ‘enriching’ and ‘extractive’ research is drawn. In the case of the SANREM project in Cotacachi, Ecuador, scientists carried out enriching research activities of interest to local people as a wayto generate social capital for conducting basic research which does not have an obvious, immediate local benefit. The requested research did not have a conventional participatory methodology but provided valuable products (educational opportunity, germplasm, community visualization tools, and information) to the indigenous community in exchange for time and resources to conduct research on more basic natural resource questions. We argue that in the Andean context the key to reconciling the needs of scientists and of local needs is seeking new forms of equitable collaboration which reach beyond the present and now somewhat tired discourse of ‘participation’.展开更多

In the paper, we develop a combustion chamber for the Stifling engine which aims to generate 3-5 kWe electric power. The combustion chamber includes three main components: combustion module, heat exchange cavity and thermal head. Its feature is that the structure can divide "combustion" process and "heat transfer" process into two appar- ent individual steps and make them happen one by one. Since natural gas can mix with air fully before burning, the combustion process can be easily completed without the second wind. The flame can avoid contacting the thermal head of Stifling engine, and the temperature fields can be easily controlled. The designed combustion chamber is manufactured and its performance is tested by an experiment which includes two steps. The experi- mental result of the first step proves that the mixture of air and natural gas can be easily ignited and the flame burns stably. In the second step of experiment, the combustion heat flux can reach 20 kW, and the energy utiliza- tion efficiency of thermal head has exceeded 0.5. These test results show that the thermal performance of com- bustion chamber has reached the design goal, The designed combustion chamber can be applied to a real Stifling engine heated by natural gas which is to generate 3-5 kWe electric power.展开更多
