A survey on the methods of detecting a human body inside surrounding captured images of a machine, optimizing one of these methods and finding an injured person in a captured picture is our target. Using neural networks for better detection and making RBFN network, make it possible to use high altitude captured pictures with lower resolution and light changes. Modifying RBFN to MRBFN network for an optimized processing with effect of living signs seems to be an applicable approach. These methods can extended from detecting an injured person in a captured picture, to analyze the medical images like detecting a special pattern in MRI picture. Of course it’s a start for many future... 

Earlier research mainly have addressed to a part of the M&A phenomenon and rarely have conducted multi-aspect analysis of it. On the other hand, unfortunately a high percentage of M&A deals collapses before completion which implicates there is not a thorough understanding of all the variables involved in the M&A process. Therefore, we conducted a case study research which is better qualified at providing in-depth, multi-aspects and multidisciplinary understanding and therefore novel findings of this multifaceted and complex phenomenon, M&A, in an emerging market context. Our research aims to highlight these questions: 1. what are the underlying incentives behind M&A deals initiation? 2. What... 

Industrial programs are known as engine of development plans in Iran. These types of programs also known as mega projects that have multi dimension nature of the project. In fulfillment of doing mega project, consideration on many dimensions as several engineering process, complex project management issues, social responsibilities, cultural issues, and many other affecting dimensions should be done.As a point of view in successful project, the management (HAROLD KERZNER, 2006) requires finishing projects at cost, time, and quality and so on, but success of the industrial programs and mega projects also have effects on countries economy and improvements.For a country development, it is needed... 

It has been about a decade that cosmological datas have shown the universe is accelerating. To describe this acceleration, cosmologosts use cosmological constant as the easiest way to describe,or the modified gravity models or smooth dark energy models as other ways. In this thesis we solved a specific structure formation problem, density contrast, for linear structures, in two different methods. the first method was LCDM model and the second method was a specific f (R) gravity model. We shpwed that these two solutions are about the same.
 

In the modern world of software engineering, software evaluation has earned a special position. The presence of consultation companies in evaluating the software will confirm this specialty. Web technology, as a new trend in computer science, has attracted the attention of many researchers and practitioners. As known nowadays, most of the software solutions are Web-based. Such software is technically called Web application. The methods of evaluating Web application include the use of traditional metrics in software engineering. The intelligence of the Web in computer science has been the core of much research.
This study is intended to use intelligence, as one of the new features of the... 

The increasing frequency and intensity of disasters worldwide are giving rise to increasingly complex situations. Affected communities often struggle to respond effectively and rapidly using only their existing resources and infrastructure, including formal emergency response systems. In this context, voluntary efforts by citizen volunteers play an important role in enhancing communities’ adaptive capacity and resilience. Nevertheless, the considerable potential of volunteer-led disaster response is undermined by challenges related to coordination and organizing. Realizing this potential requires appropriate organizing solutions. This dissertation explores various approaches to organizing...
