In this paper by using numerical evaluation the effect of balancing drupes of water hammer on tunnels lining is considered. In case of not arrangment of these reservoirs, the tunnel lining will be damaged of cyclic powers of water hammer. In this research, function of balancing reservoir of water hammer on cover of tunnels to the barriers’ turbine is simulated by numerical methods and Plaxis 3D...

Assembly Line production is one of the widely used basic principles in production system. The problem of Assembly Line Balancing deals with the distribution of activities among the workstations so that there will be maximum utilization of human resources and facilities without disturbing the work sequence. Research works reported in the literature mainly deals with minimization of idle time i.e...

Optical projection tomography enables 3-D imaging of colorectal polyps at resolutions of 5-10 µm. This paper investigates the ability of image analysis based on 3-D texture features to discriminate diagnostic levels of dysplastic change from such images, specifically, low-grade dysplasia, high-grade dysplasia and invasive cancer. We build a patch-based recognition system and evaluate both multi...

This paper presents an algorithm, based on the self-balancing binary search tree, to form learning groups. It aims generate groups that are intra-homogeneous (student performance similarity within group), inter-homogeneous (group between groups), and of balanced size. The algorithm mainly uses 2-3 tree 2-3-4 as two implementations a student blocks with close GPAs (grade point averages) sizes. T...

With the growth in customers’ demand diversification, mixed-model U-lines (MMUL) have acquired increasing importance in the area of assembly systems. There are generally two different approaches in the literature for balancing such systems. Some researchers believe that since the types of models can be very diverse, a balancing approach without simultaneously sequencing of models will not yield...

This mixed method study compared mathematics achievement in two third-grade classrooms using two different representations: virtual manipulatives which has dual codes of visual and symbolic representations, and physical manipulatives for instruction in fraction addition and balancing algebraic equations. The research employed a within-subjects crossover repeated measures design, administered pr...
