Research ArticleOpen accessEvery word in the titleMODERATING ABILITY OF ITEM RESPONSE THEORY THROUGH PRIOR GUESSING PARAMETERSiow Hoo Leong, Siew Eng Ling, Rasidah MahdiA psycho-technology approach to discouraging guessing in multiple-choice formatted item can be done through reducing the a priori guessing probability of an item. This study proposes a psychometrics framework of Item Response Theory (IRT) to model the effect of having various priori guessing probabilities across different items. A prior guessing parameter is proposed to serves as a moderator of the … …Journal of Mathematics and Statistics, Vol. 9, Issue 4 · 26 Sep 2013 · 7,116 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSequential Multiple Response Optimization for Manufacturing Flexible Printed CircuitPichpimon Kanchanasuttisang, Pongchanun LuangpaiboonProblem statement: Flexible Printed Circuit or FPC, one of automotive electronic parts, has been developed for lighting automotive vehicles by assembling with the LED. The quality performances or responses of lighting vehicles are relied on the circuit width of an FPC and the etched rate of acid solution. According to the current operating condition of an FPC company, the capability … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 12 Mar 2012 · 6,859 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFinite Element Study of the Stress Response of Bi-Directional Corrugated-Strip Core Sandwich BeamSuphattharachai Chomphan, Manit LeekitwattanaProblem statement: In engineering design, stress affects the size of structural member. A suitable topology of structure should be designed to optimize the stress. Approach: This study presents an alternative topology of truss-like core sandwich beam referred to here as bi-directional corrugated-strip core topology. A finite element method is used to study the stress response of three point loaded truss-like … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 7,060 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleConstrained Response Surface Optimization for a Laser Beam Welding ProcessPongchanun LuangpaiboonProblem statement: On a current operating condition of a laser beam welding process in the hard disk drive industry, it has been found that shear strength of the head support and suspension assembly is slightly higher than customers' specification. This situation leads to an inspection with a large sample size and a high frequency. Shear strength is not only one … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 29 Jan 2011 · 7,368 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExtension and Prerequisite: An Algorithm to Enable Relations Between Responses in Chatbot TechnologyAbbas Saliimi Lokman, Jasni Mohamad ZainProblem statement: Artificial intelligence chatbot is a technology that makes interactions between man and machines using natural language possible. From literature, we found out that in general, chatbot are functions like a typical search engine. Although chatbot just produced only one output instead of multiple outputs/results, the basic process flow is the same where each time an input is entered, … …Journal of Computer Science, Vol. 6, Issue 10 · 24 Aug 2010 · 16,993 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of N-Acetylcysteine on Auditory Brainstem Response Threshold Shift in Rabbits Exposed to Noise and Carbon MonoxideSeyedbagher Mortazavi, Masoud Motalebi Kashani, Ali Khavanin et al.Problem statement: Noise Induced Hearing Loss (NIHL) is one of the most important occupational disease in worldwide. NIHL has been found to be potentiated by simultaneous Carbon monoxide (CO) exposure. Exposure to noise plus CO is common in occupational and environmental settings. Free radicals have been implicated in cochlear damage resulting from exposure to noise and due to CO hypoxia … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 8,040 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Comparative Study between Abdominal and Laparoscopic Diathermy in Evaluation of Ovulatory Response in Women with Polycystic Ovary SyndromeNabila K. Yaaqoub, Enas M. Yaseen, Ruqiya S. TawfeekProblem statement: To compare the effects of both abdominal and laparoscopic diathermy (PCOS) on the ovulatory process. Design: Prospective study. Setting: Tikrit Teaching Hospital, Iraq. Approach: A total of 40 infertile patients, these patients were divided into two groups, each group of 20 patients. The first group was undergoing abdominal diathermy; while the second group undergoing laparoscopic diathermy. The ovulatory … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 4 · 31 Dec 2009 · 7,133 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWave V Detection Using Instantaneous Energy of Auditory Brainstem Response SignalM. M. Rushaidin, Sh-Hussain Salleh, Tan Tian Swee et al.Problem statement: ABR machine is a well known machine that has been used on detection of hearing problem especially for babies or children. In ABR, wave V is the most prominent and robust wave that has been used as indicator of hearing loss. However, a fast detection of the wave V is necessary in order to implement newborn hearing screening. … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,785 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessment of Surface Treatment on Fatigue Life of Cylinder Block for Linear Engine using Frequency Response ApproachM. M. Rahman, A. K. Ariffin, S. Abdullah et al.Objectives: This study was focused on the finite element techniques to investigate the effect of surface treatment on the fatigue life of the vibrating cylinder block for new two-stroke free piston engine using random loading conditions. Motivation: An understanding of the effects related to the random loading is necessary to improve the ability of designers to accurately predict the fatigue … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 8,139 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleElucidating the Mechanism(s) of Hormesis at the Cellular Level: The Universal Cell ResponsePaul S. AgutterMany environmental stressors elicit biphasic effects from single cells. Such cellular hormesis may be interpreted in terms of (a) the superimposition of simple biochemical processes or (b) the non-specific behaviour of the cell. The latter approach is emphasized in this article and identified with the universal cell response (UCR); however, the importance of identifying molecular-level concomitants of the UCR is … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 13,112 accessesView PDFCite
