We consider a Potts model on a Cayley tree with competing nearest neighbor J1 and next-nearest-neighbor interactions Jp restricted to spins belonging to the same branch of the tree with four spins and investigate the problem of phase transition for paramagnetic phases of this modeFull Terms & Conditions of access and use can be found at https:/

The accurate estimation of pressure drop during multiphase fluid flow in vertical pipes has been widely recognized as a critical problem in oil wells completion design. The flow of fluids through the vertical tubing strings causes great losses of energy through friction, where the value of this loss depends on fluid flow viscosity and the size of t

Introduction: The roots of E. longifolia or Tongkat Ali have been used to in traditional medicine as well as supplements and food additives. Many chemical compounds have been detected in extracts of its roots which is believed to be responsible for its medicinal properties. In this study, our objectives were to study the effect of the E. Longifolia

Portable Eye Examination Kit retina (Peek Retina™, Peek Vision Ltd, UK) and 3D Printed Ophthalmoscope (3DPO) were identified to have acceptable image for retinal evaluation, however the retinal images quality in term of blood vessels visibility between both devices was uncertain. This study was conducted to compare the quality of image based on b

Fractal dimension (Df) has been identified as indirect measure in quantifying the complexity of retinal vessel network which is useful for early detection of vascular changes. Reliability studies of Df measurement on retinal vasculature, has been conducted on retinal images processed by using semi-automated software which only permits image with 45

This paper presents the formulation of a nonlinear adaptive backstepping force control in grasping weight-varying objects using robotic hand driven by Pneumatic Artificial Muscle (PAM). The modelling and control problems arise from the high nonlinear PAM dynamics and the inherent hysteresis leading to a lack of robustness in the hand’s performanc

Imperforate anus is a malformation of the anus, children with such type of congenital malformation usually undergo reconstructive surgery and be looked after by pediatric surgery nurses due to the problems with constipation and fecal incontinence after the colostomy is closed. Lack of control over bowels may affect a child’s psychosocial adjustme

The call for an Integrated Islamic Education has become widely discussed in the modern era, especially within the South Asia region including Malaysia and Indonesia.

Extracting essential oils from plants require an efficient method. Currently, different methods of extraction are used to extract the roots of Eurycoma longifolia jack. Each extraction method affects the yield and composition of the extract produced. In this study we compared three different extraction methods ; Microwave Assisted Extraction (MAE),
