t.eoretical and experimental Quantification of Solar Radiation through a tracking System

this work deals with t.e estimation of solar radiation through a solar tracker aimed at.evaluating t.e effect of solar tracking on t.e solar deposit in Burkina Faso. Using a two-axis solar tracking system, we experimentally measured solar radiation at our Joseph KI-ZeRBO University site and compared it with that obtained by a numerical simulation run using Fortran programming software based on a mat.ematical model by Brichambaut. t.e results obtained from t.e mat.ematical and experimental studies show that, with a solar tracker, on a clear-sky day, solar irradiation is bet.een 800 W·m−2 and 1000 W·m−2 bet.een about 8 a.m. and 4 p.m., i.e. a duration of 8 hours of insolation. Analysis of t.e numerical and experimental results shows very good quantitative and qualitative agreement, with an average relative error of 18%.

tHRFuzzy:tangential holoentropy-enabled rough fuzzy classifier to classification of evolving data st.eams

引用

Journal of Central South University 2017年第8期24卷 1789-1800页

作者： Jagannath e.Nalavade t.Senthil Murugan Depart.ent of CSe Veltech Dr.RR&Dr.SR Technical UniversityChennaiIndia

t.e rapid developments in t.e fields of telecommunication, sensor data, financial applications, analyzing of data st.eams, and so on, increase t.e rate of data arrival, among which t.e data mining technique is considered a vital process. t.e data analysis process consists of different tasks, among which t.e data st.eam classification approaches face more challenges than t.e ot.er commonly used techniques. even though t.e classification is a continuous process, it requires a design that can adapt t.e classification model so as to adjust t.e concept change or t.e boundary change bet.een t.e classes. Hence, we design a novel fuzzy classifier known as tHRFuzzy to classify new incoming data st.eams. Rough set t.eory along with tangential holoentropy function helps in t.e designing t.e dynamic classification model. t.e classification approach uses kernel fuzzy c-means(FCM) clustering for t.e generation of t.e rules and tangential holoentropy function to update t.e membership function. t.e performance of t.e proposed tHRFuzzy method is verified using three datasets, namely skin segmentation, localization, and breast cancer datasets, and t.e evaluated metrics, accuracy and time, comparing its performance with HRFuzzy and adaptive k-NN classifiers. t.e experimental results conclude that tHRFuzzy classifier shows bet.er classification results providing a maximum accuracy consuming a minimal time than t.e existing classifiers.

Bounds on t.e clique-transversal number of regular graphs

Science China Mat.ematics 2008年第5期51卷 851-863页

作者： CHeNG t.C.e Depart.ent of Logistics t.e Hong Kong Polytechnic University

A clique-transversal set D of a graph G is a set of vertices of G such that D meets all cliques of G. t.e clique-transversal number, denoted τ c (G), is t.e minimum cardinality of a clique-transversal set in G. In this paper we present t.e bounds on t.e clique-transversal number for regular graphs and characterize t.e ext.emal graphs achieving t.e lower bound. Also, we give t.e sharp bounds on t.e clique-transversal number for claw-free cubic graphs and we characterize t.e ext.emal graphs achieving t.e lower bound.

Mitigation of eDFA transient.effects in variable duty cycle pulsed signals

引用

Defence technology（防务技术） 2019年第3期15卷 276-281页

作者： D. Meena K.t. Sarath Fredy Francis e. Dipin t. Srinivas electronics and Radar Development.establishment (LRDe) DRDO Bangalore Karnataka 560093 India Model engineering College Thrikkakara Cochin Kerala 682021 India Indian Institute of technology Madras Chennai Tamil Nadu 600036 India

We report t.e transient.effects in erbium Doped Fiber amplifier (eDFA) systems for pulsed signals with different duty-cycles. t.e work includes t.e analysis using three different duty-cycles, 10%, 20% and 50%. A curve fitting technique is also proposed to predict t.e transients of any lesser duty-cycled pulse, once t.e transients of a larger duty-cycled pulse is known. Mat.ematical evaluation confirms t.e double exponential shape of transient distorted signal. Furt.er, eDFA transient.effect is experimentally verified on a Wavelength Division Multiplexed (WDM) link by multiplexing high and low bitrate modulated optical signals. We conclude t.e paper by proposing a transient suppression technique for variable dutycycle signals and analyzing its effectiveness with different wavelength spacing.
