Analysis of Hierarchical Diff-EDF schedulability over heterogeneous real-time packet networks.
September 1, 2007... INTRODUCTION Recently, many applications of computer networks rely on the ability of the network to provide Quality of Service (QoS) guarantees. These guarantees are usually bounded in the form of delay, bandwidth, packet loss rate and...

Arabic speech pathology therapy computer aided system.
September 1, 2007... INTRODUCTION Computer aided therapy software is a new concept. in the field of medicine, specially in the speech process, It is an orientation to the introduction of different algorithms in the illness correction and default detection....

Adaptive control of networked systems in the presence of bounded disturbances.
September 1, 2007... INTRODUCTION In recent years, the discipline of networked control systems has become a highly active research field. An NCS is a control system in which a data network is used as feedback media. The use of networks as media to...

A Swarm-based Distance Vector Routing to support multiple Quality of Service (QoS) metrics in mobile Adhoc Networks.
September 1, 2007... INTRODUCTION Mobile adhoc network (MANET) is a collection of mobile devices which form a communication network with no pre-existing wiring or infrastructure. Routing in MANETs is challenging since there is no central coordinator that...

Support measure admissibility based on operations on instance graphs.
September 1, 2007... INTRODUCTION The primary goal of data mining is to discover interesting patterns in data. Since patterns that appear frequently may interesting or important, a primitive sub-task in achieving this goal is answering the question: how...

Experimental comparison between evolutionary algorithm and barycenter heuristic for the bipartite drawing problem.
September 1, 2007... INTRODUCTION The Evolutionary Algorithm (EA) offers the promise of a widely applicable, robust global search strategy. Good EA-performance is a matter of finding a proper balance between exploitation and exploration. This in turn is...

Policy-based security for wireless components in high assurance computer systems.
September 1, 2007... INTRODUCTION High assurance computer systems are those that require convincing evidence that the system adequately addresses critical properties such as security and safety objectives (8). They are used in environments where failure can...

Combined DWT-DCT digital image watermarking.
September 1, 2007... INTRODUCTION The development of effective digital image copyright protection methods have recently become an urgent and necessary requirement in the multimedia industry due to the ever-increasing unauthorized manipulation and...

Data-driven forecasting schemes: evaluation and applications.
September 1, 2007... INTRODUCTION A reliable multi-step forecasting tool is very useful to a wide array of real-world applications to predict the future states of a dynamic system. In industrial applications, for example, forecast information can be used to...

Parallel algorithms for string matching problem on single and two dimensional reconfigurable pipelined bus systems.
September 1, 2007... INTRODUCTION String matching mainly deals with the problem of finding all the occurrences of a string in a given text. String matching had been one of the most extensive problems in computer technologies during the past two decades....

Performance comparison of different image sizes for recognizing unconstrained handwritten Tamil characters using SVM.
September 1, 2007... INTRODUCTION Handwriting has continued to persist as a means of communication and recording information in day-to-day life even with the introduction of new technologies. Recognition of characters is an important area in machine...
