The most important stage in image processing and human activities recognition is the segmentation method. So many researchers give us many ideas and techniques but still there is no perfect technique to segment object and catch all requirement, Our contribution here is using spread seed technique to segment objects inside the image and expand regions of object if the object consist of different pixels intensity via using threshold of pixel intensity .changing values of threshold make this technique more reliable and distribute objects according to size of segment area then we can store the objects recognized by the size and image histogram for retrieve them to rearrange the objects within binary tree.

In this paper, we solve the integro-differential equation by using new integral transform called Tarig transform. New theorems for the transform of integrals are introduced and proved.

The denoising procedure attenuates the image noise while preserving its edges and fine details. In computed tomography, images are degraded by additive white Gaussian noise because of different acquisition and systems errors. Due to noise existence, specialists may encounter certain difficulties to analyze or extract the useful information from noisy images. This paper presents a novel implementation of the phase preserving algorithm to denoise CT images. The phase preserving is a very powerful noise reduction algorithm but it tends to remove specific small details from the processed CT images supposing these details as noise. Therefore, the Wiener filter is used along with the latter algorithm to reduce the noise and aids in conserving the minor medical details. Moreover, selected adjustments to the phase preserving algorithm are applied to obtain a better image contrast and quality. The performance of the proposed scheme is assessed on naturally and synthetically degraded CT images using the universal image quality index (UIQI) metric. Results show major improvement not only in noise attenuation but also in preserving the small details.

We present the case of a 30 years old patient (male) victim of a high speed car crush assisted by ED Craiova. Coma, severe head trauma, serious chest trauma with multiple rib fractures, bilateral lung contusions, pericardial fluid, multiple spine and pelvic unstable fracture, medullar injury, progressive shock, paroxysmal cardiac dysrhythmias. Increased levels of CKMB with atipical evolution for a myocardial contusion. Two cardiopulmonary arrest (asystole), both resuscitated.\nTaking into account the kinematics and severity of thoracic trauma, myocardial contusion was the first diagnostic hypotheses, but it was also considered the possibility of an acute coronary syndrome, toxicologic ethyology and the spinal cord damage as causes of cardiogenic shock and cardiac rhythm disturbance. \nThe association of neurotrauma, haemorrhage and pulmonary contusion limited treatment of an potential acute coronary syndrome, fast volume replacement and the possibilitys to assist ventilation, in context of shock and risk of secondary brain and spinal injury.\nSpecifying these contingencies determined the management orientation for both possible primary reperfusion and advanced management for neurotrauma.

In the last decades, the number of patent applications has significantly increased, but with regional variations according to the specific development conditions. The study of the determinant factors of patent applications by countries could offer useful information for the evaluation of the degree of competitiveness in order to take decisions for regional development. The purpose of this research work is to achieve a description of patent applications evolution in order to evaluate the effects caused by a series of determinant factors. For this, the authors studied the patent applications and determinant factors of innovation from 40 countries, in the time period 1963-2010. The analysis was made using variance analysis (ANOVA) and panel analysis in statistical software R. The data used are taken from different databases available on the websites of national government agencies and institutions. \nThe results obtained showed that, between continents and between time periods there are significant differences of the mean number of patent applications. The determinant factors with a significant impact on patents applications number are Gross Domestic Product per employed person and the number of education years.

Transition to a market economy in Central and Eastern Europe countries was not successful for most of them, and to this situation have contributed a number of external and internal factors. After the collapse of communism the focus was on restructuring the industries through privatization process. Privatization in Central and Eastern Europe can not be seen only as a change of ownership but rather as a complex economic transformation. The transition to private ownership has not been fast, the privatization mechanisms differ from one state to another, which led to the establishment of a long period of decline. This article seeks to analyze the main aspects of the transformation from Central and Eastern European societies by approaching the main issues of privatization and its evolution in the most important central and eastern European countries.
