Research ArticleOpen accessAll words, across the recordGRAPHSJ 3: A MODERN DIDACTIC APPLICATION FOR GRAPH ALGORITHMSGianluca Costa, Claudia D’Ambrosio, Silvano MartelloIn 2009 the authors developed an open source Java application and framework, GraphsJ, to help the students in their approach to the study of graph algorithms, by guiding them to understand their logical structures through experiments on numerical instances. After four years, the availability of Java 7 and of new tools suggested the implementation of a new major release. We … …Journal of Computer Science, Vol. 10, Issue 7 · 10 Feb 2014 · 7,857 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Novel Odor Key Technique for Security Applications Using Electronic Nose SystemMahmoud Z. IskandaraniProblem statement: A novel approach to security applications that makes use of odors as password generators is developed and tested. The developed system detects and converts odor signals that are randomly selected to binary signals and then intelligently compares them with previously stored values. Approach: The interface device in question then either opens its interface if comparison is successful or … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,186 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBone Microarchitecture by Dentistry Digital X-Ray (BµA-DDX) Software: A Pilot Study of the Analysis of Bone Density using Digital Dental X-RaysAdriane Yaeko Togashi, Adair Santa Catarina, Lucas Renato Piana Batistussi, Guilherme CoelhoThe Bone Microarchitecture by Dentistry Digital X-Ray (BµA-DDX) software was designed to determine jaw bone quality using digital dental X-rays. In order to identify patients with a suspicion of low bone density, a system was developed to evaluate bone microarchitecture through the analysis of samples collected in digital panoramic X-rays. The samples were collectedat two sites of the mandible: alveolar … …Current Research in Dentistry, Vol. 6, Issue 2 · 23 Feb 2016 · 7,471 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAN APPROACH TO MITIGATE DENIAL OF SERVICE ATTACKS IN IEEE 802.11 NETWORKSAdriano Cesar Ribeiro, Alex Roschildt Pinto, Geraldo Francisco Donega Zafalon et al.Wireless networks are widely deployed and have many uses, for example in critical embedded systems. The applications of this kind of network meets the common needs of most embedded systems and addressing the particularities of each scenario, such as limitations of computing resources and energy supply. Problems such as denial of service attacks are common place and cause great inconvenience. … …Journal of Computer Science, Vol. 10, Issue 1 · 12 Nov 2013 · 8,621 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOptimal Decentralized Spectral Resource Allocation for Orthogonal Frequency Division Multiple Access Downlink of Femto Networks Via Adaptive Gradient Vector Step Size ApproachLamia Benmesbah, Bingo Wing-Kuen Ling, Vikram Chandrasekhar et al.Problem statement: For the Orthogonal Frequency Division Multiple Access (OFDMA) downlink of a femto network, the resource allocation scheme would aim to maximize the Area Spectral Efficiency (ASE) subject to constraints on the radio resources per transmission interval accessible by each femtocell. Approach: An optimal resource allocation scheme for completely decentralized femtocell deployments leads to a nonlinear optimization problem because … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 14 Jan 2012 · 7,637 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordVisually Impaired Children's Acceptances on Assistive CoursewareNurulnadwan Aziz, Nur Hazwani Mohamad Roseli, Ariffin Abdul MutalibProblem statement: The government of Malaysia is considering serious efforts in promoting the usage of computers among disabled people. Currently, the availability of computer applications especially related to creative contents for disabled people in Malaysia is infancy and very expensive. Research and expertise in the area of Assistive Technology (AT) in Malaysia is still uncommon and not extensively utilized. Therefore … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 7 Sep 2011 · 7,277 accessesView PDFCite
