This paper presents a Memory integrated Artificial Bee Colony Algorithm (MABC) to solve the Vehicle Routing Problem with addition of Backhauls and Time Windows, known as the VRPBTW. In VRPBTW, a homogenous fleet of vehicles are utilized to deliver goods to linehaul customer set and pick up goods from backhaul customer set. Vehicle capacity, sequence of linehaul/backhaul and time windows are the three of major constraints for this problem. The VRPBTW’s objective is to determine the optimal routes with minimum of total distance that satisfies all constraints. The proposed algorithm was tested on Gelinas’s VRPBTW benchmark problems. MABC is developed by adding the memory to Artificial Bee Colony (ABC). The local search algorithms including λ-interchange and 2-opt* are utilized to search for the better solutions. The computational results show that MABC significantly yields the good solutions in terms of total travelling distance. Finally, it can be concluded that the performance of the proposed MABC algorithm is superior to the existing studies in term of quality solution.","PeriodicalId":9207,"journal":{"name":"British Journal of Applied Science and Technology","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87118088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research studied the variation of Nitrogen Oxide concentration in an urban area at 30 m and 110 m above ground by applying the HYSPLIT model to simulate the backward trajectories movement of air mass using the past 3 days of data from an air quality and microclimate monitoring station at Kasetsart University, Bangkok from January 2016 to February 2017. The results showed that the concentration of Nitrogen Oxide at 30 m above ground is higher than the concentration at 110 m above ground. The concentration trended to increase in winter (October 2016 to February 2017). According to the backward trajectories modeling, the major direction of air mass movement at 30 m above ground, category 1 (N-NE) and category 2 (NE-E), occupying 86% of total movement direction (concentration of NOx ranged from 4.02 to 96.35 ppb) meanwhile the major direction of air mass movement at 110 m above ground, category 1 (N-NE) and category 2 (NE-E), occupying 79% of total movement direction (concentration of NOx ranged from 3.93 to 51.50 ppb). The air mass moved through the different land use types, human activities and industrial areas. This study can be applied as a guideline for microclimate surveillance and monitoring of NOx concentration influenced by air mass movement.","PeriodicalId":9207,"journal":{"name":"British Journal of Applied Science and Technology","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81200821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two species of colored rice, namely Riceberry (RB) and Hom-Nil (HN) were employed as samples for germination. The results indicated that total phenolic content, total anthocyanin content, GABA content and antioxidant activity (FRAP and DPPH assay) were considerably higher when colored rice was soaked at pH 6 compared to pH 7 (P < 0.05). The bioactive compounds and proximate compositions of fresh rice noodles were significantly enhanced when addition of Germinated Colored Rice (GCR) increased (P < 0.05). However, texture profile analysis of the fresh GCR noodle had remarkable decrease in terms of cohesiveness, springiness and chewiness which had lowest values at 50% supplement of GCR. Lightness (L*) of the noodle reduced whereas redness (a*) and yellowness (b*) incresed significantly (P < 0.05) when GCR addition increased. Additionally, there was no distinct difference in sensory evaluation scores from thirty untrained panelists by adding 10 and 20% GCR in the fresh noodle (P > 0.05). This study concluded that the incorporation of GCR up to 20% into the formulation could be used to increase nutritional value of the fresh germinated colored rice noodle.","PeriodicalId":9207,"journal":{"name":"British Journal of Applied Science and Technology","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82580153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main aim of this research is to develop a simulation methodology in order to calculate temperature and wear variations of different materials (here: aluminium on cast iron) in general dry sliding contacts. The developed simulation methodology is based on an uncoupled thermo-mechanical and wear analysis. The widely spread finite element software Abaqus is used for the numerical investigations. For calibration and validation, experimental investigations are performed with a pin-on-disc test bench. A comparison between the experimental and the numerical results is presented and discussed. The experimental results are in close agreement with the numerical results. For the considered test case (rotational velocity of the disc=300 rpm and load on the pin=110 N) the numerical analysis predicts a maximum temperature of 63°C in comparison to 65°C in the experiment. For the considered test case (rotational velocity of the disc=600 rpm and load on the pin=150 N) the simulation predicts a maximum temperature of 93°C in comparison to 97°C in the experiment. The study concludes that the developed simulation methodology is accurate and can be used to calculate temperature and wear variations of different materials in general dry sliding contact.","PeriodicalId":9207,"journal":{"name":"British Journal of Applied Science and Technology","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72604878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
