Motivated by an empirical analysis of the Childhood Asthma Management Project, CAMP, we introduce a new screening procedure for varying coefficient models with ultrahigh dimensional longitudinal predictor variables. The performance of the proposed procedure is investigated via Monte Carlo simulation. Numerical comparisons indicate that it outperforms existing ones substantially, resulting in si...

Slow light has been extensively studied for applications ranging from optical delay lines to single photon quantum storage. Here, we show that the time delay of slow-light significantly improves the performance of the narrowband spectral filters needed to optically detect ultrasound from deep inside highly scattering tissue. We demonstrate this capability with a 9 cm thick tissue phantom, havin...

the performance of organizational projects has an eminentrole in successfully implementing strategies. this is especially importantin project-based organizations whose business is projects. parentorganization as one of the groups that determines projects’ success andfailure has various functions regarding its projects. identifying thesefunctions develops literature on project-based organization...

This study evaluated 20 general circulation models (GCMs) of the Coupled Model Intercomparison Project, Phase 5 (CMIP5), which provide the prediction results for the period of 2006 to 2014, the period from which the observation data (the Global Precipitation Climatology Project (GPCP) data) are available. Both the GCM predictions of precipitation and the GPCP data were compared for three data s...

The effect of silica fume on the performance, mechanical properties, durability and air tightness airtight concrete was studied. results showed that with increase content, performance will decrease, compressive strength first, reach highest when content 8%, then it decrease gradually. With corrosion resistance coefficient increased gradually, decreased. permeability decreases improved obviously...

The project management domain includes many well-defined methodologies such as the Project Management Body of Knowledge: PMBoK (Project Management Institute, 2008). On the other hand, project failures rate is quite high (Woolridge, Hale, Hale, & Sharpe, 2009). An interesting question is: Does using these methods improve project performances? This paper reports on a study that was performed to i...

role in project success is not addressed in project management literature. The purpose of this article is to address this gray area. In this article our focus is to identify a set of people-related project performance factors, and to understand how these factors interact with one another. Using these inter-relationships, we develop a model to analyze the project manager’s role in improving proj...

Low power consumption has been established as the third main design target for digital systems together with performance and area. Consequently, accurate estimators of the power consumption at the system as well as the lower levels of abstraction are necessary. A large number of embedded computing applications are power or energy critical. Early work on processor analysis had focused on perform...

The purpose of this research is to investigate the role project appraisal in performance Made Rwanda projects, focusing on a soap-making at Sulfo Rwanda. quantitative and qualitative approaches descriptive design were employed. study surveyed 103 respondents, selected from population 146 individuals using Krejcie Morgan's (1970) table. Ninety-nine respondents randomly through simple random samp...
