projects scheduling by the project portfolio selection, something that has its own complexity and its flexibility, can create different composition of the project portfolio. an integer programming model is formulated for the project portfolio selection and scheduling.two heuristic algorithms, genetic algorithm (ga) and simulated annealing (sa), are presented to solve the problem. results of cal...

an integrative approach of data envelopment analysis (dea) and malmquist productivity indicator for performance analysis of projects in subsea r&d; center (srdc) is presented. it is noticeable that, an output based model with constant efficiency was used for data analysis. furthermore, since the dea approach is merely used for homogeneous units, it was assumed that all the projects according to...

Design, fabrication, and testing of multi-axis CMOS piezoresistive accelerometers is described. Vertical axis accelerometers have been fabricated in multiple processes using a production tested maskless bulk etch step. Horizontal axis accelerometers have also been fabricated and require an additional assembly step. Acceleration sensing in based on the piezoresistive behavior of the gate polysil...

Objective: Irritable Bowel Syndrome (IBS) is a chronic, disabling, and functional disorder of the gastrointestinal tract in the absence of identifiable structural disorder. The present study aimed to investigate the relationship between sensory processing sensitivity and life style with perceived stress considering mediating role of duration of syndrome in patients with IBS using structural equ...

Sensitivity analysis studies the effect of a change in given parameter to response function system under investigation. In reactor physics, this usually translates into study how cross sections and fission spectrum modifications affect value multiplication factor, delayed neutron fraction or void coefficient for example. Generalized Perturbation Theory provides useful tool assessment adjoint we...

In this paper, we report the numerical calculations for a thermo-optical model and the temperature sensitivity of a fiber Bragg grating (FBG) sensor. The thermally-induced behaviors of a FBG sensor in the gas nitriding process were analyzed for temperatures ranging from 100–650 ◦C. The FBG consisted of properly chosen photosensitive fiber materials with an optimized thermo-optic coefficient. Th...
