The discrete cosine transform (DCT) has widely been used in image and video compression coding. However, the conventional DCT causes severe block artifacts in the compressed image in low-bit-rate coding applications. The block effect is perceived as visible discontinuities cross the block boundaries. Many researchers have proposed other techniques, such as the filter bank approach, to remove or suppress this undesirable feature.
Sparkmatrix, a provider of online tools for property managers, has positioned one of its next-generation service provisioning commodities at IEEE 802.16 networks (or Wimax). The company successfully delivered IEEE 802.11 and IEEE 802.16 services to their customers. To improve the service quality and coverage, they considered deploying relays in order to erase any possible black notes and service deficiencies in buildings and offices.
Viking Aerospace Ltd., a company providing engineering support services for Unmanned Aircraft Systems (UAS), is currently seeking approval of a Supplemental Type Certificate (STC) for the DHC-3 Turboprop conversion kit. This conversion kit has provisions for a nose fuel tank. A separate STC is desired for the addition of this tank. In order to gain approval for the fuel tank STC, compliance must be shown to FAR 23 regulations.
This internship project with Deep Compression Inc. aims to produce a prototype demonstrating a new technique for asymmetric lossless data compression. Unlike conventional compression techniques, this prototype will allow representational information to be recovered using an algorithmic recovery procedure, algorithmic self-organizing structure (ASOS).
A system for the detection of deep vein thrombosis (DVT), a disease where blood clots form in the legs, has been developed by the student and his supervisors at UBC. The current project is aimed at determining an approach using pre-screening criteria to evaluate the system in a clinical setting without having to examine hundreds of patients to obtain reliable results, as a consequence of the low incidence of the disease.
The project involves creating a vision based system to perform multi-camera 3D tracking of persons in an indoor environment. The implementation of this system will be using Open Vision Library (a standard library for image processing that is designed with hardware acceleration in mind) and it will be running on one or multiple processor hardware platform developed by LightHaus. LightHaus Logic is a Vancouver-based company that develops compact high-performance systems for advanced video analytics and embedded computer applications.
The test characterization of the stress-strain relationship and the fatigue/failure behaviour under combined mechanical-thermal cyclic loadings for pressure vessels in the petrochemical industry is quite expensive and time consuming. An alternative approach is the finite element numerical analysis which requires an accurate and reliable mathematical constitutive model for the metallic materials. In this project, a temperature-dependent elastoplastic material model will be developed.
The emissions of NOx and SO2 are subject to increasingly severe environmental regulations. In an effort to reduce the amount of NOx and SO2 emitted by DuPont’s industrial facilities, the intern will develop new capabilities in NOx and SO2 absorption modeling. During the project, the intern will begin by learning the ChemKin™ software, which he will apply to simulate the absorption of NOx and SO2 into caustic. Caustic is a liquid solution currently used to “clean” exhaust gases from NOx and SO2 in wet scrubber equipment.
The objective of this project is to contribute a quantitative framework for analyzing potential inefficiencies of current practices at Bell Canada in the early stages of telecommunication service provisioning, particularly pre-sales and network request sub-processes. Models of these processes incorporating randomness are to be estimated from past data and utilized as a basis for efficiency improvement using both simulation and analytical optimization tools.
Identifying early onset of cardiac diseases is not easy and can be very expensive. For this reason, the first symptom of cardiac problems is often catastrophic for patients. The ultimate goal of this project is to produce a low-cost screening device that effectively identifies the presence of the disease early, allowing patients to take corrective action in terms of lifestyle, diet and stress management in order to eliminate the need for surgical intervention and/or drug therapy.
