A MULTIOBJECTIVE MODEL OF WHOLESALER-RETAILERS' PROBLEM VIA GENETIC ALGORITHM

MAHAPATRA, NIRMAL KUMAR,BHUNIA, ASOKE KUMAR,MAITI, MANORANJAN 한국전산응용수학회 2005 Journal of applied mathematics & informatics Vol.19 No.1

In the existing literature, most of the purchasing models were developed only for retailers problem ignoring the constraint of storage capacity of retailers shop/showroom. In this paper, we have developed a deterministic model of wholesaler-retailers' problem of single product. The storage capacity of wholesaler's warehouse/showroom and retailers' showroom/shop are assumed to be finite. The items are transported from wholesaler's warehouse to retailers' Own Warehouse (OW) in a lot. The customer's demand is assumed to be displayed inventory level dependent. Demands are met from OW and that spaces of OW will immediately be filled by shifting the same amount from the Rented Warehouse (RW) till the RW is empty. The time duration between selling from OW and filling up its space by new ones from RW is negligible. According to relative size of the retailers' existing (own) warehouse capacity and the demand factors, different scenarios are identified. Our objectives are to optimize the cost functions of wholesaler and two retailers separately. To solve this problem, a real coded Genetic Algorithm (GA) with roulette wheel selection/reproduction, whole arithmetic crossover and non-uniform mutation is developed. Finally a numerical example is presented to illustrate the results for different scenarios. To compare the results of GA, Generalised Reduced Gradient Method has been used for the problem. Also, a sensitivity analysis has been performed to study the variations of the optimal average cost with respect to the different parameters.

The rising trend of breast cancer both in developed and developing countries is a real threat challenging all efforts to screening, prevention and treatment aspects to reduce its impact. In spite of modern preventive strategies, the upward trend of breast cancer has become a matter of great concern in both developed and developing countries. Chittaranjan National Cancer Institute is a premier regional cancer institute in eastern region of India catering to a large number of cancer patients every year. A pilot case control study of fifty breast cancer patients and 100 matched controls was conducted during 2013 to evaluate the effects of habitual factors like working in night shift, not having adequate sleep, and not sleeping in total darkness on breast cancer of women. The study revealed that not sleeping in total darkness was associated with higher odds of outcome of breast cancer of women. This positive correlation can play a vital role in formulation of preventive strategies through life style modification.

Asok Kumar Ghosh 국민체육진흥공단 한국스포츠정책과학원 2010 International Journal of Applied Sports Sciences Vol.22 No.1

The study was undertaken with a view to investigate the physiological responses of amateur boxers during specific activity in the boxing arena, with special reference to their physiological evaluation in the laboratory. The study was carried out on 6 elite Indian National boxers in 3 phases. In phase 1, the VO2max of the boxers was evaluated in the laboratory following a graded running protocol on a treadmill. In Phase 2, the boxers were evaluated in the boxing arena, during simulated boxing on a punching bag for 4 rounds of 2 min duration with 1 min rest pauses in between. The movements were kept similar to actual boxing and the punching frequencies were kept fast and individualized. The physiological variables were recorded on a COSMED K4 RQ portable telemetric gas analyzer (Cosmed, Italy). In Phase 3, heart rate and blood lactate responses of the boxers were observed during sparring for 2X6 rounds in the boxing ring, for 3 times during the training phase, to observe the lactate tolerance capacity. After the end of activity in each phase, a blood sample was collected from the fingertip for estimation of whole blood lactate on an YSI portable 1500 sport model lactate analyzer (YSI, USA). The mean VO2max of the boxers was 59.5 ± 4.7 ml/kg/min on the treadmill. The mean peaks VO2 of the boxers in 2X4 simulated rounds were 56.1, 57.5, 57.7 and 59.3 ml/kg/min, respectively. The mean heart rate and blood lactate were 192 bpm and 13.6 mMol/L, and were observed to be higher than most of the intermittent team events. The present study highlighted that the amateur boxers participating in 2X4 rounds, should be able to tolerate a high blood lactate concentration (14-15 mMol/L) and a high heart rate (190-200 b/min) over a total duration of one bout (11 min). The on court training in amateur boxing imparted high demands on cardiorespiratory and metabolic variables.

Heart Rate and Blood Lactate Responses during Execution of Some Specific Strokes in Badminton Drills

( Asok Kumar Ghosh ) 한국스포츠정책과학원(구 한국스포츠개발원) 2008 International Journal of Applied Sports Sciences Vol.20 No.2

The present article is an attempt to investigate the physiological demand of the most popular strokes, like, over head smash, over head toss, over head drop and the shadow movements in badminton drills on the basis of heart rate and blood lactate concentration. The study will certainly help the coaches and other specialists in finding out the demands and intensities of these badminton strokes and movements on the court. In the 1st phase of the study, VO2max of all the players was determined in the laboratory following a graded exercise protocol on a bicycle ergometer, till exhaustion. The 2nd phase of the study consisted of playing over head smash, over head toss, over head drop and shadow movement on the court on different days. The player had to play on one side of the court and he was fed the shuttle from the opposite side. The heart rate was measured on a PE 3000 (Polar Electro, Finland) polar sport tester (heart rate telemetric device) for every 5 sec interval and the blood lactate concentration; on an YSI 1500 sport model lactate analyzer. The mean VO2max of the present players was 57.4±7.02 ml/kg/min. The mean heart rates during overhead smash, overhead drop, overhead toss and shadow movements were 183±5, 180±6, 178±8 and 182±7 beats/min, while the mean blood lactate were 11.6±1.9, 10.2±1.2, 10.7±1.1 and 12.2±2.1 mMol/L, respectively. The study indicated that the heart rate and blood lactate responses during execution of overhead smash, overhead drop, overhead toss and shadow movements were high and no differences existed among them. Theses popular and common badminton strokes exertedhigh cardiovascular and metabolic stress on the players. Repetitive execution of these strokes during training may develop both the aerobic and anaerobic capacities of the players.

Synthesis and performance of polythiophene-iridium oxide composite as counter electrode in dye sensitized solar cell

Asok Aswathy,Haribabu K 한국물리학회 2023 Current Applied Physics Vol.49 No.-

Efficient electron transfer from the counter electrode (CE) to the redox couple electrolyte is the key process in the operation of dye-sensitized solar cells (DSSC). Polythiophene-Iridium oxide (PTh/IrO2) nano composite synthesized by reflux reaction method at different mass ratios (1:4, 1:2 and 1:1) has been explored as an effective electrocatalyst for the triiodide reduction in DSSC. The results of electrochemical impedance spectroscopy (EIS), bode plot studies and Tafel polarization method suggested that the composite synthesized at mass ratio 1:1 exhibited low charge transfer resistance (R ct), faster transport of electrons and excellent electrocatalytic activity. The PTh/IrO 2 composite synthesized at mass ratio 1:1 based DSSC exhibits a conversion efficiency of 3.01%, open-circuit voltage of 0.60 V and a short-circuit current density of 10.1 mA/cm 2. The facile synthesis procedure and attractive electrochemical properties benefit PTh/IrO 2composite to be used as a credible CE in DSSCs.

K Asok Kumar,M Umamaheswari,AT Sivashanmugam,V Subhadradevi,SS Somanathan,TK Ravi 경희대학교 융합한의과학연구소 2009 Oriental Pharmacy and Experimental Medicine Vol.9 No.4

Oxidative stress plays an important role in the pathogenesis of various diabetic complications and small intestine is vulnerable to damage resulting in morphological and functional changes. In this study, the effects of Asystasia gangetica leaf extract (AGLE) on oxidative stress status in small intestine of diabetic rats were examined. The leaves of Asystasia gangetica was extracted with 70% ethanol. Oral administration of AGLE once daily (100 mg/kg and 200 mg/kg b.w.) for 28 days to diabetic rats significantly (P < 0.05) increased antioxidant levels of catalase, superoxide dismutase, glutathione peroxidase, glutathione, GSSH, carbohydrate metabolizing enzyme, glucose-6- phosphate dehydrogenase. The increased levels of protein carbonyl content, lipid peroxidation and xanthine oxidase/xanthine dehydrogenase in diabetic rats were reverted back to near normal levels on treatment with AGLE. Both doses of AGLE offered significant activity (P < 0.01) against oxidative damage and were comparable with standard, glibenclamide. The results revealed the occurrence of oxidative stress in small intestine during diabetes and suggest the potential of AGLE as an antioxidant in protecting the tissue defense system against oxidative damage in streptozotocin-induced diabetes.
