Research ArticleOpen accessIn the abstractThe Relationship between Exclusive-Or and the Unique Existential QuantifierM. A. Nabulsi, A. M. AbdallaProblem Statement: The efficiency of computer architecture design is affected by the components used. Establishing a relationship between exclusive-or (XOR) and the unique existential quantifier provides alternative system implementations. Approach: Applications of XOR and the unique existential quantifier were explained. Then, prepositional logic was used to establish the relationship between them. Results: Different quantified assertions with two variables that use … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 7,475 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTransmission Congestion Management by Determining Optimal Location of FACTS Devices in Deregulated Power SystemsSeyed Abbas Taher, Hadi BesharatIn a deregulated electricity market, it may always not be possible to dispatch all of the contracted power transactions due to congestion of the transmission corridors. The ongoing power system restructuring requires an opening of unused potentials of transmission system due to environmental, right-of-way and cost problems which are major hurdles for power transmission network expansion. Flexible ac transmission systems … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 8,507 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluating Plant Species Suitability for a Substrate-Free Tropical Green RoofBruno R. Silva, André Mantovani, Dulce G. Mantuano et al.Greenroofs reduce building exterior-interior thermal flux and mitigate high internal air temperatures, especially in tropical climates. Tropical greenroofs are given little attention and their use remains restricted to a very low percentage of roofs due to high costs compared to traditional roofs, weight overload (mainly due to the chosen substrate) and potential waterproofing problems. We here present an alternative greenroof … …OnLine Journal of Biological Sciences, Vol. 18, Issue 4 · 11 Oct 2018 · 7,529 accessesView PDF Cite

Research ArticleOpen accessIn the abstractConceptual Design, Analysis and Construction of a Fixed-Wing Unmanned Arial Vehicle for Oil and Gas Pipeline SurveillanceAliyu Bhar Kisabo, Charles Attah Osheku, Sholiyi Olusegun SamuelOil and Gas Pipelines consists of pipes, compressors and pumps. These are frequently located in environments that are difficult to monitor and secure (e.g., creeks and remote areas). Attacks or damage to such installations can lead to enormous ecological impact and loss of revenue. Developing and implementing monitoring systems that can continuously assess the state and condition of oil and … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 1 · 1 Jun 2017 · 10,538 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBlindLogin: A Graphical Authentication System with Support for Blind and Visually Impaired users on SmartphonesYean Li Ho, Bachir Bendrissou, Afizan Azman, Siong Hoe LauMost graphical password systems on smart phones do not consider the needs of blind and visually impaired users. The main objective of this paper is to propose a new graphical authentication system which combines the usability of the graphical password with the security of the textual password and allows all types of users, including the blind and visually impaired users … …American Journal of Applied Sciences, Vol. 14, Issue 5 · 23 May 2017 · 8,599 accessesView PDF Cite

Review ArticleOpen accessIn the abstractPromising Effects of Beta-Glucans on Metabolism and on the Immune Responses: Review ArticleViviam de Oliveira Silva, Natália Oliveira de Moura, Larissa Jahnel Rodrigues de Oliveira et al.A public health issue, Diabetes mellitus, affects millions of people around the globe. Ingestion of foods with a low glycemic index - fiber-rich meals-such as beta-glucans, is increasing as an important alternative for diabetes control. These compounds act reducing parameters such as blood glucose, cholesterol and triglycerides, by decreasing the absorption of glucose and lipids by enterocytes and eventually promote … …American Journal of Immunology, Vol. 13, Issue 1 · 29 Mar 2017 · 12,689 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHigh Performance and Low Leakage 3DSOI Fin-FET SRAMD. Sudha, Ch. Santhirani, Sreenivasa Rao IjjadaIn recent semiconductor designs, the major key factors: Competent device simulations, precise device characterization, well power optimization, new architectural design and cost-effective fabrication drives the designers attention towards multi gate transistors as an alternative to MOSFET. Non planner device structures are a competitive edge over planner devices. Silicon-on-Insulator (SOI) FinFETs are hopeful among variety of multi-gate structures as they have … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 9 Feb 2017 · 7,353 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIncrease in Crude Protein Content of Milk Replacers with Vegetable Protein: Effect on Health and Dairy Calves' PerformanceEvangelina Miqueo, Thais Manzoni Torrezan, Nathalia Britto Rocha et al.The use of milk replacer instead of whole milk may be an economical alternative to calf-rearing systems. However, together with the volume fed, its composition is critical for high performance, especially regarding the origin of the protein. Two milk replacers with different protein content were evaluated to see the effect on the performance of calves. Thirty-three Holstein calves were distributed … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 1 · 6 Feb 2017 · 7,779 accessesView PDF Cite

EditorialOpen accessIn the abstractProtecting crop species from biotic and abiotic constraints in the era of Global Change: are we ready for this challenge?Marco Landi, Giovanni BenelliReliable and affordable supply of food is of crucial importance to the progress and stability of human societies. During the last century, we have assisted to an extraordinary increase of crop yields, especially for the most widespread and consumed crop species, such as rice, wheat, corn and soybean. The Broadbalk experiment, one of the oldest continuous agronomic experiments in the … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 4 Jun 2016 · 8,402 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCombining SURF and MSER along with Color Features for Image Retrieval System Based on Bag of Visual WordsHeba A. ElnemrContent-Based Image Retrieval (CBIR) has received an extensive attention from researchers due to the rapid growing and widespread of image databases. Despite the massive research efforts consumed for CBIR, the completely satisfactory results have not yet been attained.
