The present study focuses on the sizing and aerodynamic contour design of a two-seater 1000 kg gross take-off mass winged hybrid airship. Unlike the conventional hybrid airships, which stay aloft and takeoff with the help of VTOL propulsion systems, a winged hybrid airship requires a certain speed to takeoff by utilizing lift coming from its aerody

Purpose – The purpose of this paper is to develop a hybrid algorithm using differential evolution (DE) and prediction error modeling (PEM) for identification of small-scale autonomous helicopter state-space model. Design/methodology/approach – In this study, flight data were collected and analyzed; MATLAB-based system identification algorithm w

An important concern in metal forming is whether the desired deformation can be accomplished without defects in the final product. Various ductile fracture criteria have been developed and experimentally verified for a limited number of cases of metal forming processes. These criteria are highly dependent on the geometry of the workpiece and cannot

Ceramic composite made up of zirconia-toughened alumina (ZTA) with TiO2 as additive was constructed via a solid-state sintering route. The Vickers hardness of the obtained ZTA–TiO2 was evaluated at various levels of the TiO2 addition. Every sample was dry mixed, uniaxially pressed and sintered at 1600 1C for 1 h in a pressureless condition. The p

I found him very friendly with an open mind regarding things related to Islam, academics and the general lifestyle. He was exploring new ideas and directed me and the group towards innovative thinking “thinking beyond the box“. Had an unquenchable thirst for new knowledge or information about knowledge. Intelligent, curious and passionate about

The use of electric field in solid/liquid separation is especially effective with sludges containing colloidal particles for which conventional mechanical dewatering is not very successful. Such sludges are usually highly compressible, and mechanical dewatering is impeded due to very high hydrodynamic resistance of the sludges. On the other hand, t

Bacteriocins produced by a variety of lactic acid bacteria (LAB) are gaining more attention for not only as alternative food preservative but also as therapeutics agent. A bacteriocin, Ent C4L10, was produced by coagulase negative Enterococcus mundtii strain C4L10 (Accession No. KC731423) previously isolated probiotic from Malaysian non-broiler chi

Cobalt-platinum (Co-Pt) nanocrystalline alloy films were electrodeposited using a novel stable single-bath system containing a complex forming additive which stabilised the Co+2 ions and enhanced codeposition with platinum complexes. The compositions of the electrodeposits was controlled by adjusting the metal ions ratio in the electrolytic bath an

Baby dumping issue has become a serious phenomenon in Malaysia. The fact that newborn babies being dump to die at the most inappropriate places such as toilet or junkyard is such a heinous crime. Despite various steps taken by governments and societies, the statistic of baby dumping is escalating in Malaysia. This should not be happening in our cou

The act of abandoning or disposing foetus and newborn is widely known as baby dumping in Malaysia. Even though the statistics of the crime is difficult to obtain and mostly underreported, the issue has attracted much attention and being considered by the society in most part of the world as a heartless crime. The offender could be charged under rel
