Recent Patents on Computer Science - Volume 3, Issue 1, 2010

The last decade has witnessed rapid development of diverse emerging wireless systems such as the thirdgeneration (3G) and beyond wide-area cellular networks, municipal area networks and local area hotspots. It is widely envisioned that these coexisting heterogeneous networks could complement each other in capacity and coverage and would converge into a common platform over the Internet Protocol (IP). In line wi Read More

We propose adding users' Media Access Control (MAC) addresses to standard X.509 certificates to provide more secure authentication. Recent patents demonstrate efforts on a X.509 certificate by adding security features in order to establish secure communications. The MAC address can be added by the issuing Certification Authority (CA) to the “extensions” section of the X.509 certificate. We demonstrate that when two Read More

This paper deals with the question: what are the implications of connectionism for theories of computation? Three possible answers are examined. 1. A theory of implementation: connectionist representations are not semantically structured. Connectionism can be deemed a theory for implementing classic symbolic computation. 2. Representational connectionist computation: connectionist networks compute by exploiti Read More

Customer churn prediction is one of the most important problems in customer relationship management (CRM). Its aim is to retain valuable customers to maximize the profit of a company. To predict whether a customer will be a churner or non-churner, there are a number of data mining techniques applied for churn prediction, such as artificial neural networks, decision trees, and support vector machines. This pap Read More

Model order selection of an Autoregressive Moving Average (ARMA) process is an important problem. This paper presents a new algorithm for the estimation of an ARMA and autoregressive with exogenous input (ARX) model orders based on a rounding approach which uses the floor and the ceiling functions. The rounding approach is implemented to deal with the precision of binary words. The proposed algorithm is based on Read More

Among all the proposed techniques for software testing, the model-based testing technique has gained attention with the popularization of models in software design and development. Of particular importance are formal models with precise semantics. However, the most researches argue that building an abstract formal model for the system under test requires excessive amount of skills from the tester and a large effort in ter Read More

Software piracy is the major challenge to software providers, and most trade organizations today face problems with software piracy. As a result, there are several developed systems available in the market to deal with this problem. Unfortunately, the majority of these systems do not provide an appropriate solution and the problem has not been solved yet. After reviewing the nature of existing systems, the author found that t Read More
