The aim of this research is to determine a forecasting model of the price of gold in relation to the rate of interest from 1971–2013 that would benefit wealth managers in their forward interpretation of capital market expectations. It is not a model for market makers, since the price-setting dominance of banks in the physical as well as derivativ

This paper presents state feedback control via linear matrix inequality (LMI) for vibration control of a flexible link manipulator (FLM) system. FLM is a negative imaginary (NI) system with high amplitude vibration and oscillation. In this work, pole placement controller (PPC) which is NI controller is used to control the FLM vibration, to achieve

Hypertension or high blood pressure (BP) is a condition that has a significant impact on the world's population morbidity and mortality. The World Health Report 2002, stated that high blood pressure caused 7.1 million deaths throughout the world, which was approximately 13% of total deaths worldwide. The body's arterial blood pressure contr

Hypertension (HPT) is the most common co-morbidity among type 2 diabetes mellitus (T2DM) patients which causes increased risk of morbidity and mortality from stroke, heart failure and heart attack¹. Thus, keeping blood pressure within targeted control level is crucial to reduce the cardiovascular complications in T2DM patients. The HPT control sta

This study examines the relative efficiency of 31 plantation companies in Malaysia based on data for the first three cumulated quarters of 2012 (January - September). The study applies an adopted version of Data Envelopment Analysis (DEA). DEA is a tool used to weigh the inputs/outputs and measure the relative efficiency of decision-making units. T

We consider Bose–Einstein condensates with two- and three-body interactions periodically varying in time. Two models of time-dependent three-body interactions, with quadratic and quartic dependence on the two-body atomic scattering length as, are studied. It is shown that parametric instabilities in the condensate lead to the generation of Farada

In order to evaluate the efficiency of sludge dewatering, specific parameters such as settling velocity (Vs) and sludge volume index (SVI) have to be measured. However, problems arise when these parameters are used for the evaluation of efficiency using M. oleifera as natural phytocoagulant or sludge conditioner. Using statistical optimization, it

We study localized nonlinear excitations of a dilute Bose–Einstein condensate (BEC) with spin–orbit coupling in a deep optical lattice (OL). For this we introduce a tight-binding model that includes the spin–orbit coupling (SOC) at the discrete level in the form of a generalized discrete nonlinear Schrödingerequation. Existence and stability

Background:Spermatogenesis is a process where proliferation and differentiation of spermatogonial stem cell (SSC) into haploid sperm cells in the testis. Azoospermia patients have impaired spermatogenesis where they have difficulty to get normal sperm. The purpose of this study is to proliferate and differentiate SSC-like cell in in vitro culture f
