The design and development of a pressure sensor based typing biometrics authentication system (BAS) is discussed in this paper. The dynamic keystroke, represented by its time duration and force generates a waveform, which when concatenated results in a user’s typing pattern for the typed password. The design of the BAS is in two stages, whereby t

Sapium baccatum is usually used as a timber. Its medicinal values are not well known and very little research has been conducted concerning the plant. Consequently, this study was conducted to observe toxicity effects of hexane extract of stem bark of S. baccatum. The toxicity effects were assessed through observation of physiological changes of th

A rigid-flexible manipulator may be assigned tasks in a moving environment where the winds or vibrations affect the position and/or orientation of surface of operation. Consequently, losses of the contact and perhaps degradation of the performance may occur as references are changed. When the environment is moving, knowledge of the angle α between

This paper presents the results of an experimental work carried out to find the wall pressure distribution in a suddenly expanded duct. The enlarged duct is attached to the exit of a convergent- divergent axisymmetric nozzle. The area ratio (i.e. ratio between cross sectional area of the sudden expansion duct and the nozzle exit area) considered in

POF (Plastic Optical Fiber) is more suitable than the quartz optical fiber for indoor LAN (Local Area Network), for example in-home or office networks because of its flexibility and ease of connection by relatively large core diameter.1 x 2 optical switches for indoor LAN using POF have been developed. For switching by movement of a POF, large disp

Play is children’s natural tendency and widely regarded as providing a rich context for children’s learning in the field of early childhood education. A commitment to play has underpinned many traditional approaches to early childhood curriculum. Pertaining to the matter of partnership with parents, there was evidence indicating that many pre-s

IBDV outbreak had been reported to infect broiler chicken in Malaysia and cause high mortality. It had been reported that the virulence and pathogenicity of the virus is related to its coated protein, specifically the VP2 hypervariable regions. To study this, the nucleotides and protein of the local IBDV isolate was sequenced and analyzed by compar

In this paper, we attempt to provide mathematical models of Mendelian and Non-Mendelian inheritances of the bisexual population system having Fisher’s 1:1 principle. In our model, we always assume that distributions of the same phenotype of female and male populations are equal. We study the evolution of a Mendelian trait. As an application of a

We consider a Potts model on a Bethe lattice with competing nearest-neighbour J and next-nearest-neighbour interactions Jp. The phase diagram of this model was studied by Ganikhodjaev et al. In this paper we investigate the problem of phase transition for the considered model and show that for some parameter values of the model there is phase trans

The 4th International Conference on the Advancement of Science and Technology 2012 (iCAST 2012), with theme 'Contemporary Mathematics, Mathematical Physics and their Applications', took place in Kuantan, Malaysia, from Wednesday 7 to Friday 9 November 2012. The conference was attended by more than 100 participants, and hosted about 160 oral
