Research ArticleOpen accessIn the keywordsEfficient Technique to Detect the Region of Interests in Mammogram ImagesMoussa H. Abdallah, Ayman A. AbuBaker, Rami S. Qahwaji, Mohammed H. SalehProblem Statement: Breast cancer is the second leading cause of cancer deaths in women today after lung cancer and is the most common cancer among women. The development of efficient technique to early detect the region of microcalcifications mammogram images is a must. Approach: The method proposed in this paper is to enhance the Computer Aided Diagnosis (CAD) performance. This … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 6,629 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHigh Precision Latent Semantic Evaluation for Descriptive Answer AssessmentAmarjeet Kaur, M. Sasi KumarThis paper proposes an approach to evaluate student’s descriptive answers, using comparison-based approach in which student’s answer is compared with the standard answer. The standard answers contains domain specific knowledge as per the category (how, why, what, etc.) of questions asked in the examination. Several state-of-art claims that LSA correlates with the human assessor’s way of evaluation. With this as … …Journal of Computer Science, Vol. 14, Issue 10 · 17 Oct 2018 · 7,253 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Novel Method to Improve Weld Uniformity by Automatic Control of Current IntensityAbdul Aziz A. Morgan, Fahad A. Al-MufadiThis study aims to develop an automatic arc welding system capable of welding irregular and moving joints which are difficult to weld manually. The motivation of this research comes from the need to produce uniforms weldings on regular and irregular surfaces by automatic means. The system consists of a personal computer equipped with A/D interface card connected to an electric … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 26 Jan 2015 · 7,507 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImproving an Electrostatic Powder Coating Process via Signal to Noise Response SurfacePongchanun LuangpaiboonProblem statement: In a coating process, the master plate referenced brightness or color shade was critical to the exterior appearance on aluminum alloy wheels. The quality measures of interest are the metallic paint thickness values on four areas. Because of these lower quality levels, the manufacturer has spent more on the cost of restudy or scrap as well as the … …American Journal of Applied Sciences, Vol. 7, Issue 11 · 8 Nov 2010 · 7,476 accessesView PDF Cite

Research ArticleOpen accessIn the abstractVoltammetric Detection of Mn(II) in Blood Sample at C60 and MWCNT Modified Glassy Carbon ElectrodesMuhammed Mizher Radhi, Wee Tee Tan, Mohamad Zaki B. Ab Rahman, Anuar Bin KassimProblem statement: Glassy carbon electrode GCE was modified with different microparticles to increase the efficiency of analysis Mn2+ in blood samples by cyclic voltammetry and applied for the detection of trace Mn(II) by oxidation process. Approach: The structure and composition of the modified GCE processed by using Carbon Nanotubes CNT and C60 to produce two modified electrodes CNT/GCE and C60/GCE, … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,489 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Novel Enhancement Technique of the Hill Cipher for Effective Cryptographic PurposesA. F.A. Abidin, O. Y. Chuan, M. R.K. AriffinProblem statement: The Hill cipher is the first polygraph cipher which has a few advantages in data encryption. However, it is vulnerable to known plaintext attack. Besides, an invertible key matrix is needed for decryption. It may become problematic since an invertible key matrix does not always exist. Approach: In this study, a robust Hill algorithm (Hill++) has been proposed. … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 8,545 accessesView PDF Cite
