Brain Computer Interface (BCI) is a system to control human brain activities. BCI system was useful for the disabled or paralyzed peoples. The main objective of this work is to develop a BCI system to classify EEG stimulus pattern for motor imagery. For the improvement of classification feature extraction should be best one. Here Common Spatial Pattern (CSP) technique has been applied for extraction...
The websites usability and accessibility standards make more convenient to the internet users. The most of exists websites are failed to follow these standards. Hence, in this research study, we analyze the usability and accessibility standards of highly used websites of Sri Lankan government. The forty-seven government websites are selected to investigate the usability and accessibility guidelines...
The wireless internet service is offered to the people through Wi-Fi technology in commercial and industries. It is working based on radio waves in the spectrum. These waves are very harmful to the diseased people, signal sensitive areas. Hence it could not be utilized in environments such as hospitals, scan centers, air lines etc. To overcome these limitations, Li-Fi is the technology that is developed...
In this paper, we present the design of a Proportional Integral (PI) controller using Genetic Algorithm (GA) to control the speed of an induction motor (IM). The GA methods have been employed successfully to solve complex optimization problems. The main advantage of this metaheuristic method (GA) is its simplicity and robustness. Only speed error is employed as input to the GA so that the computational...
A proxy signature scheme is a variant of digital signature scheme in which a signer delegates his signing rights to another person called proxy signer, so that the proxy signer can generate the signature of the actual signer in his absence. Self Proxy Signature (SPS) is a type of proxy signature wherein, the original signer delegates the signing rights to himself (Self Delegation), there by generating...
A two-dimensional (2-D) system theory based iterative learning control (ILC) method for a class of linear discrete-time multivariable systems is presented in this paper. Practical ILC schemes comprise of a feed-forward learning controller along with feedback controllers for improved stability and convergence, termed as feedback assisted iterative learning control (FAILC). As a general format we consider...
This paper presents the effective method to carry out troubleshooting for electric motor mass unbalance problem based on vibration analysis. Vibration can be used to identify defects that arise from defective design, faulty installation, and wear and tear. In this paper, velocity used for measurement which relates to components fatigue based on time rate of machine motion. Besides that, frequencies...
This paper presents the effectiveness of generator auxiliary system such as seal oil system, stator cooling water system and gas control system with continuous hydrogen scavenging operation for hydrogen-cooled Synchronous Generator at power plant. Effective operation of synchronous generator depends on sufficient cooling medium (hydrogen) inside the casing. Besides that, good sealing system needed...
The reliability of interconnects continues to be a formidable challenge as dimensions shrink from generation to generation. In this paper we demonstrate barrier/seed scaling, enabled by HCMreg IONX PVD technology. We report high electromigration activation energy of ~ 1 eV, and Jmax > 6 MA/cm2, exceeding the ITRS 2007 requirements for the next several generations by a wide margin. Thinner barrier/seed...
This paper presents the use of Kullback-Leibler Distance (KLD) as part of an optimization framework to incorporate prior knowledge from field maps into non-rigid registration of echoplanar (EPI) to structural magnetic resonance brain images. An analytical expression is derived for the derivatives of KLD with respect to registration transformation parameters, which is shown to be computationally more...
In this paper a new method of experience inclusion in iterative learning controllers (ILC) is proposed. Approximate fuzzy data model (AFDM) technique has been adopted for the process of initial input selection. Instead of zero initial input assumption as in most of the ILC algorithms, in this paper the idea of using past trajectory tracking experiences in the selection of initial input for tracking...
Model predictive control (MPC) techniques have found widespread application in the chemical process industry, primarily due to explicit constraint handling ability. One limitation to these techniques is that they are based on the availability of output measurements and manipulated variable moves at the same sampling rate. In this paper, a multirate sampling approach to model predictive control is...
Nonlinear predictive control is an effective strategy for controlling nonlinear processes with constaints and time delays. In this paper a number of important issues involving the implementation of nonlinear predictive control are addressed. The most important issue is the determination of the state variable initial conditions for the prediction optimization at each time step. As long as the initial...
