Research ArticleOpen accessIn the author namesPotted Plants on Flat Roof as a Strategy to Reduce Indoor Temperature in Malaysian ClimateAsmat Ismail, Muna Hanim Abdul Samad, Abdul Malek Abdul RahmanProblem statement: The phenomenon of global warming or climate change has led to many environmental issues including higher atmospheric temperatures, intensive precipitation, increase greenhouse gaseous emission and of course increase indoor discomfort condition. Researchers worldwide collectively agreed that one way of reducing the impact of global warming is by implementing green roof technology which integrates vegetation, growing medium and water … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 3 · 30 Sep 2010 · 8,664 accessesView PDFCite
Research ArticleOpen accessIn the author namesPrevalence of Low Back Pain and its Risk Factors among School TeachersNurul Izzah Abdul Samad, Haslinda Abdullah, Saidi Moin et al.Problem statement: The objective of this study was to determine the prevalence of low back pain and the associated risk factors among primary school teachers in the Klang Valley, Malaysia. Approach: A cross sectional study was conducted in nine primary schools in the Klang Valley. The schools were selected randomly from a list obtained from the Ministry of Education. Two … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 13,228 accessesView PDFCite
Research ArticleOpen accessIn the author namesAnomaly Detection in Electroencephalogram Signals Using Unconstrained Minimum Average Correlation Energy FilterAini Hussain, Rosniwati Ghafar, Salina Abdul Samad, Nooritawati Md TahirProblem statement: Electroencepharogram (EEG) is an extremely complex signal with very low signal to noise ratio and these attributed to difficulty in analyzing the signal. Hence for detecting abnormal segment, a distinctive method is required to train the technologist to distinguish the anomalous in EEG data. The objective of this study was to create a framework to analyze EEG signals … …Journal of Computer Science, Vol. 5, Issue 7 · 31 Jul 2009 · 7,326 accessesView PDFCite
Research ArticleOpen accessIn the author namesRobust Speech Recognition Using Fusion Techniques and Adaptive FilteringS. A.R. Al-Haddad, S. A. Samad, A. Hussain et al.The study proposes an algorithm for noise cancellation by using recursive least square (RLS) and pattern recognition by using fusion method of Dynamic Time Warping (DTW) and Hidden Markov Model (HMM). Speech signals are often corrupted with background noise and the changes in signal characteristics could be fast. These issues are especially important for robust speech recognition. Robustness is a … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,993 accessesView PDFCite
Research ArticleOpen accessIn the author namesPitch and Timbre Determination of the AngklungMohd Ridzuwary Mohd Zainal, Salina Abdul Samad, Aini Hussain, Che Husna AzhariThis research describes the pitch and timbre determination of the angklung, a musical instrument made entirely out of bamboo. An angklung has two main parts: the frame and the rattle tubes. The pitch of the rattle tubes can be determined using a formula that takes into consideration the length and diameter of the air resonator. This is compared with the … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 9,715 accessesView PDFCite
Research ArticleOpen accessIn the author namesIsolated Malay Digit Recognition Using Pattern Recognition Fusion of Dynamic Time Warping and Hidden Markov ModelsS.A.R. Al-Haddad, S.A. Samad, A. Hussain, K.A. IshakThis paper is presents a pattern recognition fusion method for isolated Malay digit recognition using Dynamic Time Warping (DTW) and Hidden Markov Model (HMM). The aim of the project is to increase the accuracy percentage of Malay speech recognition. This study proposes an algorithm for pattern recognition fusion of the recognition models. The endpoint detection, framing, normalization, Mel Frequency Cepstral … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,049 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Effect of Corner Radii and Part Orientation on Stress Distribution of Cold Forging DieAhmad Baharuddin Abdullah, Kam Shwu Ling, Zahurin SamadOne of the most critical problems in cold forging is the huge stresses generated from the deformation of metal leads to die failure. The distribution of stresses mainly depends on geometry of the die. An approach to optimal design in cold forging die geometry and orientation are presented in this paper. The impression cold forging dies of the Universal joint … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,338 accessesView PDFCite
Review ArticleOpen accessIn the author namesBiopesticides as Promising Alternatives to Chemical Pesticides: A Review of Their Current and Future StatusLukmanul Hakim Samada, Usman Sumo Friend TambunanBiopesticides are living organisms or natural products that control agricultural pests including bacteria, fungi, weeds, viruses and insects. Biopesticides can be classified into different categories, such as microbial pesticides, plant-incorporated protectants and biochemicals. Biopesticides are a crucial component of integrated pest management programs for pest control, which lead to more natural alternatives to chemical pesticides that are eco-friendly and safer. … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 29 Apr 2020 · 23,614 accessesView PDFCite
Research ArticleOpen accessIn the author namesEvaluation of Energy Aspects of Apple Drying in the Hot-Air and Infrared DryersSeyed Hashem Samadi, Issa LoghmaniehDrying is an energy-intensive process. In general, heating and evaporation require large quantities of energy. This study has been conducted to evaluate analysis for dying apple slices in two drying systems including hot-air convection and infrared drying. The apple samples were dried at temperatures of 90, 120 and 150°C and radiation intensity of 0.22, 0.31 and 0.49 W/cm2 in the … …Energy Research Journal, Vol. 4, Issue 1 · 26 Aug 2013 · 8,009 accessesView PDFCite
Research ArticleOpen accessIn the author namesObservations on the Relationship between Opioid Medications, Illicit Drugs and Heroin Use in Pain PatientsDavid AlanYee, Michelle Marie Hughes, Rabia Samady Atayee et al.Problem statement: Patients on chronic opioid therapy are monitored to detect illicit drug use in order to deter diversion of their prescription opioids and to ensure medication adherence. The addictive potential of opioid drugs and their similar binding sites in the brain may make them potential gateway drugs for each other. Recent reports indicate that oxycodone has a high probability … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 1 · 7 Jun 2011 · 7,957 accessesView PDFCite
