objective: various techniques of composite placement have been used to decrease microleakage around the composite restorations. due to controversial results, the present study was conducted to investigate the effect of different placement techniques on microleakage in class v composite restorations. materials and methods: sixty class v cavities were prepared on the buccal and lingual surfaces o...

regarding the nature of non-linear discrete placement, and in order to determine the optimal capacity of the substation, the goal in the present study will be a number of local optimum points. in this research, the problem of optimal placement posts to reduce power losses by considering distributed generation (dg). in formulating the objective function, geographical distribution density in the ...

Designing network deployment requires a selected skill to perform effective planning. Within the study of wireless networking, nowadays, design-and-adjustment approach has replaced experience-based approach. Applying optimization technique on planning will reduce cost and time consumed in comparison with trial-and-error technique. GIS spatial analysis are going be useful prediction coverage sig...
