This paper presents the design and development of a technique referred to as SIPPA - Secure Information Processing with Privacy Assurance - for biometric data reconstruction. SIPPA enables a client/server model with the following two properties: (1) the client party can compare the similarity between his/her sample data with the source data on the server(More)
Several approaches have been introduced in literature for active noise control (ANC) systems. Since FxLMS algorithm appears to be the best choice as a controller filter, researchers tend to improve performance of ANC systems by enhancing and modifying this algorithm. In this paper, the existing FxLMS algorithm is modified which provides a new structure for(More)
In this paper a modified version of the Akthar's method for online secondary path modeling in active noise control systems is proposed. The proposed method defines two variable step sizes for control filter and modeling filter. The control filter step size μ m is adapted by using the variable threshold value T j and the modeling filter step size μ m is(More)
'This paper is concerned with obtaining a stereo display of a panoramic scene-It uses a iovel non_ frontal camera whose image plane is not perpen_ dicular to the optical axis as is strndarJ. ihis special imaging geometry eliminates the usual fo-cusing need of image plane movement while pan_ uing the camera to view panoramic scenes. Cam_ era_ movement thus(More)
Control and Instrumentation Group at the Centre for Development of Advanced Computing (CDAC), Thiruvananthapuram, has deployed an integrated control and monitoring system at a 210 MW thermal power plant in India. This system has all the features of an advanced Supervisory Control and Data Acquisition System (SCADA) and in addition has support for web-based(More)
