Research ArticleOpen accessAll words, across the recordPerformance Assessment of Solar Chimneys: Part 2 – Impacts of Slenderness Value and Collector Slope on Power OutputErdem Cuce, Pinar Mert CuceIn the previous part, impacts of chimney height thus pressure difference on the power output of solar chimneys have been numerically evaluated. Within the scope of this research, slenderness and slope of collector are analysed in terms of their potential influence on average velocity of air at the chimney inlet. The analyses are based on a commercial and reliable CFD … …Energy Research Journal, Vol. 10, Issue 1 · 9 Jul 2019 · 6,851 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTrace of Salinity of Sodium Chloride with Outcome on Enhancement Features of HerbageSona Pazdar, Saeid Eslamian, Kaveh Ostad-Ali-Askari et al.Salinity has a variety of salts, one of which is salinity of sodium chloride. Different plants react differently to salinity and their performance will vary according to their resistance, which after all the treatments, chlorophyll was measured. Depend on the outcomes of salinity consequences on native herbage; herbage features such as relative chlorophyll and chlorophyll fluorescence were decreased. Also, salinity … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 26 Jun 2019 · 7,040 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordImplementation of Line Stability Index for Contingency Analysis and Screening in Power SystemsC. Subramani, Subhransu Sekhar Dash, Vivek Kumar, Harish KiranProblem statement: Estimating the margin in the loadability of the power system is essential in the real time voltage stability assessment. Voltage stability is currently one of the most important research areas in the field of electrical power system. In power system operation unpredictable events is termed as contingency and may be caused by line outage in the system which … …Journal of Computer Science, Vol. 8, Issue 4 · 11 Feb 2012 · 7,132 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBlind Pre-Coder for MIMO System Capacity EnhancementEman Al Khader, Shereen S. IsmailIn this study, linear scheme at the transmitter is proposed as a blind pre-coder to improve the performance and enhance the channel capacity of MIMO systems with certain configurations for transmitting and receiving antennas over fading channels. This is accomplished by generating a specific linear pre-coder matrix without having any prior information about the Channel State (CS) matrix. Simulation results … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 11 Jan 2017 · 7,688 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordA GAUSSIAN MIXTURE MODEL FOR CLASSIFYING THE HUMAN AGE USING DWT AND SAMMON MAPJ. Nithyashri, G. KulanthaivelThe appearance of a human face rigorously changes with respect to age that makes Age Classification as a more challenging task. The algorithms such as, K-Nearest Neighbor (K-NN), Support Vector Machine (SVM), Radial Basis Function (RBF), motivated many Face Researchers to focus their attention in classifying the human age into various age groups. The Classification rate produced by these existing … …Journal of Computer Science, Vol. 10, Issue 11 · 20 Dec 2014 · 7,707 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPERMUTATION OF HTTPI AND HTTPS IN WEB SERVICES AGAINST ATTACKS FOR SECURITY ENHANCEMENTS. Chakaravarthi, V. RamachandranThe Hyper Text Transfer Protocol (HTTP) protocol plays a vital role in Web Services Security. Though the HTTPs provide excellent security, they are not flexible enough to allow caches. HTTPi provides high integrity and low security whereas HTTPs provide low integrity and high security. The goal of WS activity is to build up set of technologies in order to direct … …Journal of Computer Science, Vol. 10, Issue 3 · 30 Nov 2013 · 6,884 accessesView PDFCite
