Male factor is the sole reason or a component for infertility in 20 and 30% of cases respectively. The management of the disease may be via medical or surgical treatment. The surgical approach is classified as techniques which improves sperm production and delivery in order to achieve spontaneous pregnancy or sperm retrieval techniques prior to assisted reproductive techniques (ART). Varicocele...

A technique for manufacturing precise custom blocks is described. Using the tracing stylus of the mold making machine, reference markers are cut into the lateral borders of the polystyrene mold after the cavities for the blocks have been made. These markers are aligned with the central ray cross hair of the shadow tray when the blocks are mounted on the tray. The ability of the technique to enh...

In this paper a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wavelet tra...

Supervised clustering is a data mining technique that assigns a set of data to predefined classes by analyzing dataset attributes. It is considered as an important technique for information retrieval, management, and mining in information systems. Since customer satisfaction is the main goal of organizations in modern society, to meet the requirements, 137 call center of Tehran city council is ...

This paper presents a game intended to train teams that have both individual and teams goals to negotiate collaboratively in order to reach the team goal in the best way possible. We consider self-managing teams, i.e., teams that do not have a hierarchical structure. The importance of the team goal in comparison to their individual goals is touched upon, as are various conflicts that can occur ...

conclusions the present case appears to offer a safe and relatively simple method of balloon dilatation inside the lumen of the embolized fragment when the foreign body is too distal to retrieve with conventional snare systems. introduction increasing numbers of complex percutaneous coronary interventions have been accompanied by various intra-procedural complications. the fracture and emboliza...

Image search can be done using content based; colour has been taken as the property for searching. For searching local histogram searching has been used, Euclidean distance formula has been used for comparing the histograms of the images, in this paper query image is divided into two blocks, and each image in the database is also divided into two blocks and histograms are also calculated separa...

This paper proposes a content based image retrieval (CBIR) system using the local colour and texture features of selected image sub-blocks and global colour and shape features of the image. The image sub-blocks are roughly identified by segmenting the image into partitions of different configuration, finding the edge density in each partition using edge thresholding, morphological dilation and ...
