Critical point tracking is a core topic in scientific visualization for understanding the dynamic behaviour of time-varying vector field data. The topological notion robustness has been introduced recently to quantify structural stability critical points, that is, minimum amount perturbation necessary cancel it. A theoretical basis established previously relates with robustness, particular, poi...

A computer program is never truly finished; changes are a constant feature of computer program development, there are always something need to be added, redone, or fixed. Therefore, issue-tracking systems are widely used on the system development to keep track of reported issues. This paper proposes a new architecture for automated issue tracking system based on ontology and semantic similarity...

Methods have been presented to compute the vector representations of the arbitrary lines in a bilevel raster image. The image may have varying line width and irregular boundaries. Moreover, at line crossings and branches, the user has an opportunity to choose the direction in which line tracking may be continued. The usual method involves thresholding, thinning, segmentation, polygonalization, ...

Objective(s): Human Wharton’s Jelly mesenchymal stem cells (hWMSCs) are undifferentiated cells commonly used in regenerative medicine. The aim of this study was to develop a reliable tool for tracking hWMSCs when utilized as therapeutics in burnt disorders and also to optimize the cell-based treatment procedure. Materials and Methods: The hWMSCs were first isolated from fresh umbilical cord Wha...

We propose a low complexity CDMA multiuser delay tracking receiver as an alternative to the more complex extended Kalman filter (EKF) based CDMA multiuser delay trackers. It integrates delay-tracking into CDMA multiuser detection by the delay-robust successive interference cancellation (SIC) technique, which was initially proposed for robust CDMA multiuser detection when there exists time delay...

Robust and accurate pupil detection is a prerequisite for gaze detection. Hence, we propose a new eye/pupil detection method for gaze detection on a large display. The novelty of our research can be summarized by the following four points. First, in order to overcome the performance limitations of conventional methods of eye detection, such as adaptive boosting (Adabo...

The novel Multi-Receiver Vector Tracking (MRVT) architecture for the joint tracking of multiple GPS receivers, presented in our prior work [1], is improved upon in this followup paper. Improvements include an augmented software platform, Python Software Defined Radio (Python SDR), which has, among its many enhancements, a variable coherent integration interval with navigation bit wipe-off. Dyna...
