To date, it is technologically and scientifically a challenging task for scientists and researchers around the globe. Rainfall is a liquid form of precipitation that depends primarily on humidity, temperature, pressure, wind speed, dew point, and so on. Because rainfall depends on several parameters, its prediction becomes very complex. Approaches such as the back propagation, linear regression, support vector machine, Bayesian networks, and fuzzy logic can be applied, but their rate of prediction is very low, which leads to unpredictable results. This paper aims at improving the prediction of precipitation compared to Supervised Learning in Quest (SLIQ) decision trees, especially when datasets are large. Because SLIQ decision trees take more computational steps to find split points, they consume more time and thus cannot be applied to huge datasets. An elegant decision tree using gain ratio as an attribute selection measure is adopted, which increases the accuracy rate and decreases the computation time. This approach provides an average accuracy of 76.93% with a reduction of 63% in computational time over SLIQ decision trees.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128078796","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}

Many others contributions follow the simulation approach, which allows a detailed analysis but may lead to computational problems and is rather computer demanding, especially when resulting models are used to support optimization. This paper investigated the prediction reliability of two different approaches to container terminal simulation: microscopic and macroscopic. The former simulating single container movement, the latter simulating container flows movement. The microscopic model was a discrete event simulation model, the macroscopic model was a dynamic discrete time based (space-time) network assignment model. Both modelling approaches were implemented and compared taking advantage of some significant investment made by the Salerno Container Terminal (Italy) between 2005 and 2011. In particular, disaggregate (microscopic) and an aggregate (macroscopic) simulation models implemented in 2005 were validated with a large set of data acquired in 2011 after some structural and functional terminal modifications. Through this analysis it was possible to analyze the prediction reliability of both simulation approaches and to draw some operational guidelines.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122082425","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}

Several ongoing research efforts aim at improving automation of parallelisation for performance optimization of the Compute Unified Device Architecture (CUDA) software. An Application Processing Interface (API) allows the user to send commands to a graphics processing unit to draw objects on a display. The power of graphics processing unit is used by the simulation. Graphic Processing Unit (GPU) hardware designers have been developing unified processors which are increasingly resembling high-performance parallel computers. CUDA programming is an example of the well known single-programmultiple-data (SIMD) parallel programming method. This kind of programming is a popular method for massively parallel computing systems. When the mathematical models of aircraft control are appropriately designed, the simulation maybe implemented on the GPU. Mathematical models of the automated aircraft control are the systems, in which the regulation can simulate the program on the GPU. The design of mathematical model is analysed at the end of the paper.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"500 1-2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131870371","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}

Robots moving up walls or similarly rampant terrains have been analyzed and developed for a long time, we can see the many robot systems in real world scenarios for window cleaning and inspection applications. Previous researches were usually dedicated to climbing mechanisms with their locomotion and adhesion methods (magnetic, vacuum or suction cups), however, we introduce a more challenging scenario in this paper: A humanoid robot is designed to climb up a climbing wall totally autonomously. Robots are generally expected to assist human lives, and this kind of humanoid climbing robots are expected to be useful to rescue in disaster area. A special algorithm is developed to find the best route to climb up walls at each instant hold coordinate. The presented algorithm is a kind of graph algorithm on clustering, and it can analyze whether target holds are useful or not. The algorithm takes into account the specific abilities of the robot, and it is labeled ``Right Hand Search Algorithm\" (RHSA). Finally, we apply this algorithm to solve a simple practical example and simulate a basic scenario in the real environment for our humanoid climbing robot.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132578503","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}
