Effect of Noise on Gradient Systems

Abstract :-
In this paper, we generalize our work to perturbed gradient systems (PGS). For original gradient systems (GS), the change of a vector x(t) at time t is defined as the gradient vector of a function F(x) times a small negative constant. For PGS, it is assumed that the vector x(t) is perturbed by mean zero Gaussian noise. The noise can either be multiplicative or additive. In this paper, the corresponding energy functions for both cases are derived. It is found that their energy functions are very difference from F(x).

Virtual Clock Scheduling Algorithm for Video Streaming

Abstract :-
Algorithms used for scheduling play a major role in providing quality of service in video streaming. This paper describes a simulation environment that has been designed combining network simulator ns2 with video codec to predict the quality of service. Virtual clock scheduling algorithm has been applied to evaluate the performance metrics and compared with the weighted round robin (WRR) and Deficit round robin (DRR) scheduling policies.

Behavioral Reflexion Models for Software Architecture

Abstract :-
In our approach, the system engineer is supported in producing architecture documentation that reflects the intended architecture. Furthermore, discrepancies between the implementation and documentation are identified. These discrepancies are then illustrated graphically in a reflexion model, which guides debugging activities. In this research, we are concerned with architecture representations of system behaviors and focus in particular on distributed systems.

Lifetime Estimation of Composite Bone Joint Screws

Bone screws are crucial elements in treating many types of open/closed fractures and arthroplasties in different joints in the body. The life time of many plates used in the fracture treatment are dependent on the screws function. The fracture of screws at any point of their lifetime will cause failure of the treatment for that specific pathology. This may lead to increase risk of new surgeries, osteomyelitis and less commonly septic arthritis. Continue reading Lifetime Estimation of Composite Bone Joint Screws

A Novel Method of Fingerprint Classification Using Image Parameters on ANFIS

Abstract :-
Numerous algorithms have been developed to improve the speed of fingerprint recognition and this assumes prime importance when dealing with a large database of fingerprint images. In this paper, we propose a novel technique of using the image parameters like mean, median, variance, standard deviation and root mean square value to train an adaptive network based fuzzy inference system (ANFIS) to classify the test image into one of the six popular categories of fingerprints namely arch, tented arch, left loop, right loop, whorl and twin loop.
