Performance comparison between Dual-blinder and a Phasor-based Out of Step detection functions using hardware in the loop test
When an Out of Step (OOS) event occurs between two connected areas in the power system, the two areas should be separated before the OOS results in generation loss, equipment damage, and eventually a total black-out. This separation is achieved via the OOS function that implemented at specific …

Novel Technique for Gait Analysis Using Two Waist Mounted Gyroscopes
… applications such as indoor localization.</p> <p>Step detection and step length estimation are two basic and important gait analysis tasks. In fact, step detection is a prerequisite for the exploration of all other gait parameters. Researchers have proposed many methods for step detection, and …

Association of Campylobacter spp. Levels between Chicken Grow-Out Environmental Samples and Processed Carcasses
… facility, and raw poultry products. The detection of Campylobacter using both quantitative and qualitative techniques would provide a more accurate assessment of pre- or post harvest contamination. Environmental sampling in a poultry grow-out house, combined with carcass rinse sampling …

Investigation of mesophilic Aeromonas: response to hydrogen peroxide and role in false-positive Colilert reaction.
… technology system was developed as a one-step detection of both coliforms and E. coli while suppressing non-coliform heterotrophic growth. Aeromonas species were previously shown to cause production of falsepositive reaction at high cell densities (Edberg et ai., 1988). Similar results …

Gait Analysis for Pedestrian Navigation Using MEMS Handheld Devices
… and recognition of the sensor carrying mode, (2) Step detection and (3) Step length evaluation. The analysis leads to a novel step length model combining the user’s height, the step frequency and a set of three constants. First a universal model is proposed where the three constants have been …

A stain-free detection system for electrophoresis
In this thesis, a novel stain free detection system for slab gel electrophoresis is examined. Currently, stained techniques are used to identify electrophoretic bands in gels. The stains utilized in these methods involve health risks since they are mutagenic. Also stains like EtBr are intercalating …

Securing information systems against advanced persistent threats (APTs).
… often over multiple network hosts, and evade detection. APTs also use a "low-and-slow" approach over a long period of time. While APTs have drawn increasing attention from the industrial security community, recent security products are inadequate at helping companies defend against APTs …

Cardiac magnetic resonance imaging for non-invasive detection of myocardial fibrosis
… to develop non-invasive technology for the early detection of myocardial fibrosis in order to slow, treat or prevent heart disease and heart failure. Currently, detection of fibrosis in the clinic is limited. It is detected by analyzing biopsy or by enzyme-linked immunosorbent assays (ELISA) of …
