Modelling,simulation, and analysis of HAL Bangalore13; international airport

Air traffic density in India and the world at large is growing fast and posing challenging13; problems. The problems encountered can be parameterized as flight delay, workload of air traffic13; controllers and noise levels in and around aerodromes. Prediction and quantification of these13; parameters aid in developing strategies for efficient air traffic management. In this study, the13; method used for quantifying is by simulation and analysis of the selected aerodrome and air13; space. This paper presents the results of simulation of HAL Bangalore International Airport,13; which is used by civil as well as military aircraft. With the test flying of unscheduled military13; aircraft and the increase in the civil air traffic, this airport is hitting the limit of acceptable delay.13; The workload on air traffic controllers is pushed to high during peak times. The noise contour13; prediction, especially for the test flying military aircraft is sounding a wake up call to the13; communities living in the vicinity of the Airport.13

A note on the solution of fuzzy transportation problem using fuzzy linear system

In this paper, we discuss the solution of a fuzzy transportation problem, with fuzzy quantities. The problem is solved in two stages. In the first stage, the fuzzy transportation problem is reduced to crisp system by using the lower and upper bounds of fuzzy quantities. In the second stage, the crisp transportation problems are solved by usual simplex method. The procedure is illustrated with numerical examples

Influence of tuck stitch in course direction on thermal comfort characteristics of layered knitted fabrics

The thermal comfort characteristics of bi-layer knitted fabrics have been studied for shuttle badminton sportswear. Bilayerknitted fabrics are developed by changing tuck position in course direction such as 6, 10, 14 and 18 course repeat,keeping the tuck on 12th wale the same. It is observed that the greater the distance between successive tuck points, the betterwill be the air, heat and moisture transfer properties. Bi-layer knitted fabric with slack structure facilitates lower thicknessand mass per unit area, and exhibits better thermal comfort characteristics. By wear trial method, bi-layer knitted fabric withtuck on 18th course and 12th wale shows good rating compared to other bi-layer knitted fabrics. The results are discussed at95% significant level with ANOVA analysis and Friedman one-way analysis of variance

Comfort properties of double face knitted fabrics for tennis sportswear

The comfort properties of different bi-layer knitted structures made from tencel yarn as an outer layer and acrylic/micro-fibre polyester yarn as an inner layer have been studied. Six union fabrics have been produced and then analyzed objectively and subjectively for their comfort properties. The air permeability, water vapour permeability, wicking ability and drying rate are found to be higher and thermal resistance is found to be lower for bi-layer knitted fabric made out of micro-fibre polyester (inner layer) with less tuck points as compared to all other fabrics. The same structure shows good ranking on subjective rating of thermal environment scale. The results are discussed with 95% significant level with ANOVA analysis and Friedman one-way analysis of variance

Influence of tuck stitch in wale direction on thermal comfort characteristics of layered knitted fabrics

Thermo-physiological comfort of the clothing has been studied considering the ability to manage heat and to transfersensible and insensible perspiration to the environment. Four bi-layer knitted fabrics are developed by changing the tuckstitch placement in four different points on wale, such as tuck on 4th, 8th, 12th and 16th wale with same course. It isobserved that the bi-layer knitted fabric with tuck on 12th wale exhibits better air, heat and moisture transfer as comparedto those with tuck on 4th, 8th, and 16th wales. The lower thickness and low mass per unit area exhibit better thermalconductivity, air permeability, water vapour permeability, wicking, moisture absorbency, drying rate and moisturemanagement properties. The less number of tuck stitch shows better thermal comfort characteristics considering bothobjective and wear trial method. The results are discussed with 95% significant level with ANOVA analysis andFriedman one-way analysis of variance

Decent Love and Intuition Scenes of Kambaramayanam

Valmiki's epic has a special pride in the unparalleled epics that have ever appeared in the world. It is perfectly appropriate to say that Kambar gave life to all the characters created by Valmiki. Kambar has made the characters go for a walk in the atmosphere without lowering them with his own individuality and changing their character.The real meaning of the epic is "the sin of morality and defeat". It is very special that Kambar did not just emphasize that point in the epic, but also handled the news. When Rama and Sita devi see each other in the mithila scene in Kambaramayana, kambar's poetic beauty is able to understand the joy and suffering that occurred by the mind. When Raman sees Sita, he faints and all that he sees appears to be the form he has seen, and the sight of mayangal, monday and kaman being blamed, and wailing in his eyes, is seen in front of his mind. This article explains such events

Conservation of an endemic medicinal plant, Anaphalis eliptica DC. by employing plant tissue culture technique

The plant species, Anaphalis elliptica DC. (Asteraceae) is a medicinal herb endemic to high hills of Nilgiri Biosphere Reserve, the Western Ghats. The in vitro propagation study of this species by using leaf, node and shoot tip explants, revealed the following results: Among the three explants used, leaf and node responded well for callus and shoot initiations respectively. The leaf explant produced callus effectively (91%) in the MS medium supplemented with BAP and NAA at 2.5 and 0.3 mg/l respectively, whereas the nodal explant produced higher amount of shoots (92%) in the basal medium containing the growth regulator, BAP alone at 3.0 mg/l. The leaf derived callus produced higher (80%) shoot initials and shoot multiplication in the MS medium augmented with BAP and NAA at 3.0 and 0.5mg/l respectively. Similarly, the in vitro nodal derived shoots produced higher shoot multiplication (87%) in MS medium supplemented with BAP at 3.0mg/l. The regenerated shoots of both the explants were successfully rooted on MS medium supplemented with IBA and NAA at 1.0mg/l each. After sequential hardening the leaf callus derived plantlets registered higher survivability rate (80%) in the hardening medium containing decomposed coir waste, perlite and compost in the ratio of 1:1:1 by volume. Similarly, the survivability rate of nodal derived plantlets was higher (84%) in the hardening medium composed by vermicompost and soil in the ratio of 1:1 by volume

Triple Connected Domination Number of Graph

The concept of triple connected graphs with real life application was prefaced by considering the existence of a path containing any three vertices of a graph G. In this paper, we introduce a new domination parameter, called triple connected domination number of a graph. A subset S of V of a nontrivial graph G is said to be triple connected dominating set, if S is a dominating set and the induced sub graph is triple connected. The minimum cardinality undertake all triple connected dominating sets. Then which is called the triple connected domination number and is denoted by ?tc

Optimization of spinning parameters influencing the tensile properties of polyester/cotton vortex yarn

The influence of vortex spinning parameters on the tensile properties of polyester/cotton vortex yarn has been studied. Polyester/cotton yarn of 50:50 blend ratio have been produced in two different counts (Ne 20s and Ne 40s) each with four different spinning parameters (delivery speed, spindle size, feed ratio and nozzle pressure). Experiments are designed with the aid of response surface method. Accordingly different samples are produced with three levels of each parameter. The tenacity and elongation-at-break have been evaluated from the samples produced with these combinations. It is found that the tenacity of coarser count vortex yarn is influenced by feed ratio and the medium count vortex yarn is influenced by all the spinning parameters considered for this study. Elongation-at-break of coarser count vortex yarn is influenced by the feed ratio and nozzle pressure while that of the medium count vortex yarn is influenced by the spindle size, feed ratio and nozzle pressure. The interactions of spinning parameters have significant influence on the tenacity and elongation-at-break of medium count vortex yarn. On the other hand the interactions have significant influence on the coarser count vortex yarn elongation-at-break, but they do not have any influence on its tenacity
