Thisstudy is investigating the effects of project quality, project risk and project governance on project performance. Moreover, this study investigatesthe moderation effect of project leadership on these relationships. Data is collected from 354 respondents of software houses and structural equation modeling (SEM) technique is utilized for data analysis. Results suggest that project quality, p...

This paper reviews the various possible methods of passive cooling for buildings and discusses the representative applications of each method. Passive cooling techniques are closely linked to the thermal comfort of the occupants, and it is possible to achieve this comfort by reducing the heat gains, thermal moderation and removing the internal heat. In the present review the various methods ado...

This paper is aimed to investigate the design of an optimized neutron radiography system that utilizes the flux of a reactor. Moderation, collimation aspects are studied. A Monte Carlo code, MCNP4C, was utilized to achieve a maximum and more homogenous neutron flux in the collimator outlet next to the image plane, taking into account geometric characteristics. It was possible to obtain a normal...

The continuous ecological management of the Loess Plateau is known throughout the world for two strategies: the integrated soil conservation project that began in the 1970s, and the “Grain for Green” project that began in the 1990s. Six sub-catchments nested in the Beiluo River basin were selected to investigate streamflow regime variations during the two project periods. The annual streamflow ...

In this paper, we built an agent-based model to integrate and synthesize social science theories to inform online community design. As an example, we use the model to examine how various styles of moderating online conversations affect community performance. We compared three styles of moderation – no moderation, in which all members are exposed to all messages; community-level moderation, in w...

background: several landmine detection methods, based on nuclear techniques, have been suggested during the recent years. neutron energy moderation, neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are nuclear-based methods used for landmine detection. the aim of this study is to use backscattered neutron for landmine detection. materials and method...
