Breast cancer has always been a threat to many women and has become the most common disease in many developed countries and it is on the rise in developing countries. The limitations of mammography as a screening and diagnostic modality, especially in young women with dense breasts, necessitated the development of novel and more effective modalities with better sensitivity and specificity. Currently, there are several non-invasive techniques to detect breast cancer. These techniques are based...
Introduction: In wireless transmission the signal quality suffers occasional, severe degradations due to effects like fading caused by multipath propagation. To reduce such effects, diversity, as proposed by [1], can be used to transfer the different samples of the same signal over essentially independent channels. There are several approaches to implement diversity in a wireless transmission. The most common on is using the 'multiple antennas' which is used to achieve space diversity. But...

Intelligent agents are today accepted as powerful tools in a distributed environment because they are not cumbersome for the network traffic; they overcome network latency, operate in heterogeneous environment and possess fault-tolerant behavior. The concept of mobile agent is over a decade old, the technology proves not to be perfect yet, due to a misconception of an intelligent agent as a malicious agent that can be a computer virus. This paper presents a study of intelligent agent and...
This research aims at improving the performance of resource reservation protocol in mobile networks. Today, more and more portable devices such as mobile phones and laptops can easily access the wireless network. Hence, more and more people choose the wireless devices due to the convenience they provide. When a large number of these devices are accessing the mobile networks, it could lead to service disruptions, packets loss, and accumulative delay. Therefore, the question of how to provide a...

The vulnerability is present when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and thereby unexpectedly executed.SQL injection is a trick to SQL query or command as an input possibly via the web pages. They occur when data provided by user is not properly validates and is...
When Are We Ever Going to Use This? – Imaginary and Complex Numbers The number √-9 may seem impossible, and it is when talking about real numbers. The reason is that when a number is squared, the product is never negative. However, in mathematics, and in daily life for that matter, numbers like these are used in abundance. Mathematicians need a way to incorporate numbers like √-9 into equations, so that these equations can be solvable. At first the going was tough, but...
Designers' role is to develop an interaction concept for the "BookManager" application system that meets users' requirements. Designers need to know many different things about users, technologies and interactions between them in order to create effective user experiences. Designer should develop a paper prototype of the application to use as though it is the actual software. Similarly, as users see and experience design idea, can able to give better feedback that enables the...
