This paper presents aerodynamic parameters estimation techniques for an autonomous quadrotor through the implementation of Extended Kalman Filter (EKF) and Unscented Kalman Filter (UKF). EKF and UKF have known to be typical estimation techniques used to estimate the state vectors and parameters of nonlinear dynamical systems. In this paper, three m

Energy use and the associated carbon dioxide emissions, has been rising rapidly over the past few decades and about 40% of the global energy consumption is associated with the construction sector. Of late many measures have been stepped up to curb the excessive use of energy in buildings which resulted in many energy rating and benchmarking efforts

Ethical norms are so everywhere that one might be tempted to consider them as simple rational. Most civilizations use laws to implement widely accepted moral standards and legal rules. It is important to know that ethics and law are not the same. An act may be lawful but immoral/unethical or unlawful but moral/ethical. There are a number of reasons

Purpose: To determine the content of arsenic (As) in some locally available traditional medicines in the East Coast region of Malaysia. Methods: The determination of As was conducted using hydride generation-atomic absorption spectrometry (HG-AAS). Sample preparation entailed mineral acid digestion using hydrochloric acid and nitric acid mixture in

Background A thorough knowledge in the various disciplines of the basic sciences is a major importance for the practice of clinical medicine. Many basic sciences teachers share a common concern that much of what they teach in preclinical phase is soon forgotten when students move to clinical years. We therefore examined the retention of such knowle

This study was carried out at the Muar River Estuary, Johore, Malaysia. Water samples, sediment and biota that are Crassostrea iredalei, Perna viridis and Anadara granosa were collected during monsoon season in November 2005. All the samples were analyzed for the mercury concentration by using cold vapor atomic absorption spectrophotometer (CV-AAS)

This paper presents a Simultaneous wireless information and power transfer (SWIPT) system with dynamic power allocation (DPA). The system fills the gap in power splitting (PS) and time switching (TS) systems, where the different power requirements of running a sensor node (SN) and decoding information are overlooked. In the presented system, the en

Wireless Mesh Networks (WMNs) have recently gained a lot of popularity due to their rapid deployment and instant communication capabilities. WMNs are dynamically self-organizing, self-configuring and self-healing with the nodes in the network automatically establishing an adiej hoc network and preserving the mesh connectivity. Designing a routing p
