With the spreading of computers the demand for user-friendly interfaces has increased. The development of techniques based on multi-modal humancomputer intraction makes it possible to create systems which are more natural to use. We built Turk-2, a hybrid multi-modal chess-player with a robot arm and a screen-based talking head. Turk-2 can not only play(More)
The <i>openIP</i> open source image processing library is a set of c++ libraries providing tools for education, research and industrial purposes. The aim of the development is to fill in the gap between the academic and commercial utilization of image processing. The openIP libraries are interoperable, open source and easy to install. To provide fast codes,(More)
One of the rare reasons of the non malignant superior vena cava syndrome is the thrombosis of superior vena cava. Obstruction or occlusion of central veins is one of the many complications of the more and more frequently used central venous catheters and pacemaker electrodes. The authors report a case of superior vena cava thrombosis resulting in dialysis(More)
Recently a specific immunohistochemical method was introduced which may overcome these weaknesses of reticulin staining. Activated fibroblasts responsible for stromal proliferation are highlighted by increased PDGFR β expression, which can be presented by immunohistochemistry in bone marrow samples. Using this staining the pre-fibrotic stage can become(More)
Skeleton is a shape descriptor which summarizes the general form of objects. It can be expressed in terms of the fundamental morphological operations. The limitation of that characterization is that its construction based on digital disks such that cannot provide good approximation to the Euclidean disks. In this paper we define a new type of skeleton based(More)
Recent development on the fields of molecular genetics and immunology of human renal cell carcinoma (RCC) have resulted in more successful treatment of advanced and metastatic RCCs. Re-evaluation of the prognostic/predictive data aim the initial tumor staging of RCC patients to achieve better patient selection for immune and gene therapy. 125 RCC patients(More)
