This paper presents the robust control design for aircraft autopilot. The controller provides a maximum stability radius to the closed-loop system. The technique uses the notion of complex stability radius and the Linear Matrix Inequalities (LMI) to obtain the feedback controller gain. The technique is illustrated on a feedback controller of an aut

Recent advancements in signal and image processing have reduced the time of diagnoses, effort and pressure on the screeners by providing auto diagnostic tools for different diseases. The success rate of these tools greatly depend on the quality of acquired images. Bad image quality can significantly reduce the specificity and the sensitivity which

A panel of six monoclonal antibodies against the nucleocapsid protein (NP) of Newcastle disease virus (NDV) strain AF2240 was produced by immunization of Balb/c mice with purified NP. Isotyping test revealed three of the monoclonal (mAbs) were IgG1 and the others were IgG2a. All of the mAbs recognized linearized NP epitopes. The reactivity of these

Solid state bioconversion of empty fruit bunches (EFB) for lignin peroxidase (LiP) by Phanerocheate chrysosporium through optimum operating conditions of a rotary drum bioreactor (RDB) was investigated. The study was carried out in the 50L of RDB fabricated locally for 6 days of treatment. The process conditions such as initial pH of 5.5, inoculum

The present study involves two processes; modification of the tool holder for use with cryogenic cooling system, and implementation of the new design and testing its effect on tool life and product quality. Liquid nitrogen, which is the most suitable fluid for cryogenic machining is used in this work. Two different flow outlets were tested for this

This study was carried out to investigate the effect of Hibiscus sabdariffa or roselle on the progression of acute liver injury in rats. The liver injury was induced by administration of 1000 mg/kg acetaminophen intraperitoneally and aqueous extract at low (500 mg/kg) and high (1000 mg/kg) doses of H. sabdariffa was given to rats by force feeding.

Consumers’ confidence on the online transactions is vital for the continuous growth and development of electronic commerce. In the present study, we experimentally investigate the measures of consumers’ perceived security and privacy over online transactions as well as the perceived trust and reliability of online vendors in order to influence

Thermoplastic natural rubber (TPNR) nanocomposites containing organophilic layered silicates were prepared by melt blending method at 180 �C using internal mixer (Haake 600P). The aim of this study is to determine the influence of the organoclay filler on the mechanical and fracture properties. In this study, two mixing methods were employed to i

Andrographis paniculata is a Malaysian traditional herb for treatment of fever-causing diseases and diabetes. The aim of the present study was to examine the antihyperglycemic effects of different extracts (95, 50, and 20% ethanol extracts and water extracts) of A. paniculata in normal and streptozotocin-induced diabetic rats. Only the treatment wi

This research paper aims to develop an isolated-word automatic speech recognition (IWASR) system based on Vector Quantization (VQ). This system receives, analyzes, searches and matches an input speech signal with the trained set of speech signals which are stored in the database/codebook, and returns matching results to users. IWASR is meant to ass
