Research ArticleOpen accessIn the abstractOn the Use of Rolling Element Bearings' Models in Precision MaintenanceIoannis S. Zotos, Theodore N. CostopoulosProblem statement: Rolling element bearings form a very important part of machinery. The increasing demands on their continuous reliable operation under diverse environments make maintenance a very important step towards the efficient use of them. To this end, precision maintenance is a very useful practice, since it deals not only with finding a possible fault of a machine, but also … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,413 accessesView PDFCite
Research ArticleOpen accessIn the abstractManagement Policy in and Typology of State Park SystemsLowell Caneday, Debra Jordan, Yating LiangProblem statement: Parks, with particular emphasis on national and state parks, host varied interactions between human and natural systems. In particular, state park systems manage important resources related to quality of life and also are mainstays in tourism, economic development and preservation of heritage and conservation of ecosystems. Management of these parks and the human activity occurring in them is … …American Journal of Environmental Sciences, Vol. 5, Issue 2 · 30 Apr 2009 · 6,839 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe New Variable-Length Key Symmetric CryptosystemDavood Rezaei Pour, Mohamad Rushdan Md Said, Kamel Ariffin Mohd Atan, Mohamed OthmanProblem statement: In this study, we proposed a new 64-bit block cipher that accepted a variable-length key up to 512 bits, which was suitable for implementation in a variety of environments. Approach: The cipher algorithm was a 16-round Feistel network with a bijective function f and was made up of two key-dependent 16×16 S-boxes, bitwise rotations, and a carefully designed … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 7,213 accessesView PDFCite
Research ArticleOpen accessIn the abstractLectin Histochemistry Assay in Colon Tissues for Inter-species CharacterizationFaezeh Yazdani Moghaddam, Jamshid Darvish, Nasser Mahdavi Shahri et al.Problem statement: The digestive tract of animals including rodents has taxonomic and ecologic importance due to its ability in adaptation for different environments. Whereas colon absorbs water and carbohydrates, it has a vital role ecologically and physiologically and enjoys different histological structures in different rodents with various diets. Approach: Different rodent specimens belong to the family Muridae, namely Gerbilinae subfamily … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 8,685 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Approach to Dynamic Signature Verification Using Sensor-Based Data gloveShohel Sayeed, Nidal S. Kamel, Rosli BesarData glove is a new dimension in the field of virtual reality environments, initially designed to satisfy the stringent requirements of modern motion capture and animation professionals. In this study we try to shift the implementation of data glove from motion animation towards signature verification problem, making use of the offered multiple degrees of freedom for each finger and for … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,147 accessesView PDFCite
Research ArticleOpen accessIn the abstractTeaching Strategies and Class Practices of the Teachers who Teach Turkish as a Foreign Language (A Qualitative Research)Ali GocerProblem statement: In the globalizing world, second language/foreign language has gained a great importance. The importance of the foreign language teaching has increased in our time in which knowing a foreign language has deviated from being a specialty and become a feature that everyone must have. For that purpose, teachers must know the characteristics of the learners very well and … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 7,772 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards A Dynamic Object-Oriented Design Metric Plug-in FrameworkC. H. Loh, S. P. LeeProblem Statement: The evolution of software is made difficult by the need to integrate new features with all previously implemented features in software applications. Approach: present study introduced a general-purpose, platform-independent object-oriented design metric plug-in framework called jmetric intended to help building scalable, extendable object-oriented design metric plug-ins. jmetric seeks to address problem by providing the plug-in developer a structured … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,911 accessesView PDFCite
Research ArticleOpen accessIn the abstractEngineering Properties of Locally Manufactured Burnt Brick Pavers for Agrarian and Rural Earth RoadsEmmanuel Akintunde OkunadeThis study explored the possibility of employing burnt bricks produced locally by completely traditional methods as pavers on unpaved agrarian and rural earth roads in indigent communities. The pavers would eliminate the problems on such roads of being waterlogged and impassible during the rainy season months and those of environmental and health hazards from raised dust during the dry season … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,000 accessesView PDFCite
