In overlap-add synthesis of sinusoidal partials, amplitude modulation distortion can occur in the overlap region if the partial frequencies in successive frames diier. The frame-to-frame frequency changes can be accommodated by synthesizing linearly time-varying sinusoids (chirps) in adjacent frames. In this paper we present a new approach to chirp synthesis in which the distortion is eliminate...

Partial frames provide a rich context in which to do pointfree structured and unstructured topology. A small collection of axioms of an elementary nature allows one to do much traditional pointfree topology, both on the level of frames or locales, and that of uniform or metric frames. These axioms are sufficiently general to include as examples bounded distributive...

This paper deals with segmentation of image sequences in an unsupervised manner with the goal of getting highly consistent segmentation results from frame-to-frame. We first introduce a segmentation method that uses results of the previous frame as initialization and significantly improves consistency in comparison to a single frame based approach. We also find correspondences between the segme...

This paper describes the effects of induced magnetic field and partial slip on the peristaltic flow of a couple stress fluids in an asymmetric channel. The two dimensional equation of couple stress fluid are simplified by making the assumptions of long wave length and low Reynolds number. The exact solutions of reduced momentum equation and magnetic force function have been computed in wave...

We describe the design of modules in the current version of the TINA stereo based 3D vision system responsible for the recovery of geometric descriptions and their subsequent integration into partial wire frame models. The approach differs considerably from that described in an earlier version of the TINA system [2, 3]. Our strategy for the construction of partial wire frame descriptions is bro...

Partial packet recovery is well known for increasing network throughput and reducing frame retransmissions. However, partial packet recovery methods in the literature are not energy-aware and hence they are not suitable for the battery powered wireless sensor motes. We propose Green-Frag, a novel adaptive partial packet recovery mechanism that is energy friendly. It can help prolonging the batt...

In the transmission of digitally compressed video, a very important source of impairments comes from the delivery of the video stream over an error-prone channel. Partial loss or partial corruption of information can have a dramatic impact on user’s perceived quality because a localized distortion within a frame can spatially and temporally propagate over frames. The visual impact of such losse...
