introduction: the appropriate-use optimization of the limited spaces of the iranian hospitals is believed to be a crucial step towards promoting the efficiency of these healthcare centers. the issue determining the optimization patterns of the layout of units has led to a lot of efforts by researchers as it increases the efficiency of the hospitals through patients’ improvement, changing the lo...

Evaluation and prediction of performance of diamond wire saw is one of the most important factors involved in planning the dimension stone quarries. The wear rate of diamond wire saw can be investigated as a major criterion to evaluate its performance. The wear rate of diamond wire saw depends upon non-controlled parameters related to rock characteristics and controlled parameters related to ch...

Artificial Intelligence (AI) techniques are used for solving the intractable engineering problems. In this study, it is aimed to study the application of artificial bee colony algorithm for predicting the performance of circular diamond saw in sawing of hard rocks. For this purpose, varieties of fourteen types of hard rocks were cut in laboratory using a cutting rig at 5 mm depth of cut, 40 cm/...

In this project, a novel approach for motion estimation is proposed. There are few block matching algorithm existing for motion estimation. In motion estimation a new cross diamond search algorithm is implemented compared to diamond search it uses less search point. Because of this we can reduce the computational complexity. The performance of the algorithm is compared with other algorithm by m...

Based on the study of motion vector distribution from several commonly used test image sequences,a three step diamond search [TSDS]algorithm for fast block matching motion estimation is proposed in this paper .The performance of this algorithm is compared with other existing algorithms by means of error metrics and no of search points in this the simulation results shows that the proposed three...

The scheme of motion estimation is introduced to exploit the redundancy between continuous frames of 3D medical image sets in this paper. The proposed scheme is based on inter-frame motion estimation of inverse diamond search algorithm. The residual images are encoded by the Huffman encoder. The test images include five sets of the heart and two sets of the brain MRI images. The average compres...

In this paper, we introduce a diamond episode of the form s1 → E → s2, where s1 and s2 are events and E is a set of events. The diamond episode s1 → E → s2 means that every event of E follows an event s1 and is followed by an event s2. Then, by formulating the support of diamond episodes, in this paper, we design the algorithm FreqDmd to extract all of the frequent diamond episodes from a given...

Predicting the wear performance of circular diamond saw in the process of sawing hard dimensional stone is an important step in reducing production costs in the stone sawing industry. In the present research work, the effective parameters on circular diamond saw wear are defined, and then the weight of each parameter is determined through adopting a fuzzy rock engineering system (Fuzzy RES) bas...
