During PSC, the P-V characteristic becomes more complex with multiple maximum power points (MPP). Most of the conventional MPPT approaches will be trapped at the local MPP and hence limiting the maximum power generation. As such, the investigation on particle swarm optimization (PSO) based MPPT is carried out to maximize the PV generated power principally under PSC operation. The performances of conventional MPPT approach and the proposed PSO-MPPT are investigated particularly on the transient and steady state responses under various shaded conditions. The simulation results show that the PSO-MPPT is able to facilitate the PV array to reach the global MPP as well as to assist the PV array to produce more stable output power compared to the conventional perturb and observe (P&O) algorithm.","PeriodicalId":225159,"journal":{"name":"2014 4th International Conference on Artificial Intelligence with Applications in Engineering and Technology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116824985","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}

In this paper, beacon rate is fixed as 10Hz to ensure sufficient tracking accuracy. High rate means heavy channel load. If beacons are transmitted with high power, channel will become extremely congested. To alleviate channel congestion, we propose a power adjustment based congestion control method depending on channel condition evaluation and message priority. In our scheme, channel situations are evaluated by current channel load and historical transmission delay. The mechanism is evaluated in our simulation platform which comprises of traffic simulator VISSIM for realistic urban scenario and network simulator NS3 for IEEE 802.11p-based communication. Simulation results demonstrate that our scheme has improved both the system reliability and efficiency.","PeriodicalId":225159,"journal":{"name":"2014 4th International Conference on Artificial Intelligence with Applications in Engineering and Technology","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117231374","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}

Fuzzy logic is proved to be available to handle with imprecise and uncertain information in control problems. Our scheme uses channel busy ratio (CBR), local density and mobility factor as fuzzy factors to obtain the fuzzy result in order to control the beacon rate of vehicles.

Given this prelude, important optimization dual is to reduce the testing time and cost without compromising on the quality and coverage. We revisit this popular research and industry sought problem, in the historical data perspective. Proposed model has two steps. N Test cases based on multiple heuristics are recommended as part of first step. These heuristics can be derived based on test manager, test lead and/or test director requirements as inputs. The N test cases that are to be recommended will be derived upon executing evolutionary randomized algorithms such as Random Forest / Genetic Algorithm. These algorithms fed with historically derived inputs such as test case execution frequency, test case failure pattern, change feature pattern and bug fixes & associations. The recommended test suite is further optimized based on a 2 dimensional approach during second step.
