We report the second known case of bicompartmental bucket-handle tears of the medial and lateral menisci and the first documented case of the bucket-handle tears occurring simultaneously following trauma, which occurred after a motorcycle accident. Both bucket-handle fragments were displaced into the intercondylar notch. An anterior cruciate ligament tear(More)
Activated carbons were produced from compressed South African sugarcane bagasse in a pyrolysis furnace by adopting the physical method of processing viz. carbonization followed by partial gasification with steam. Feasible processing conditions were determined by varying the temperature, hold times and partial pressure of steam in the reactor at a heating(More)
Mel-Frequency Cepstral Coefficients are spectral feature which are widely used for speaker recognition and text dependent speaker recognition systems are the most accurate in voice based authentication systems. In this paper, a text dependent speaker recognition method is developed. MFCCs are computed for a selected sentence. The first 13 MFCCs are(More)
CFD modeling was used to design a simple modification to one of four compartments of a Dorr 444 clarifier at Maidstone. The model was validated via tracer testing but the best validation would be implementation of the modification. The modification consisting of a system of two baffles was installed during the season and results in terms of clear juice(More)
Speech recognition system needs to perform a high complex calculation and short time to complete it. This is a big challenge for the real-time systems. However, using a simple and fast algorithm may do this task for the slow systems. Thus, the main objective of this paper is to design and implement a Real-Time Arabic Speech Recognition system using MATLAB(More)
Norit Carbon has developed a chemically regenerable activated carbon (SPARAC) that is suitable for sugar decolourisation. Previous evaluation of this activated carbon showed promising results, and Norit developed another grade of SPARAC that had faster adsorption kinetics. This carbon has been evaluated in terms of its colour removal performance after(More)
