ATransputer computation power is used to carry out complicated needed computation (reading sensors data, deciding actions, outputting wheels data, ... system monitoring). Robot control mythology was run on a parallel computing environment known as Transputers. The Transputer embedded real-time controller was used onboard the robot to meet various intelligence requirements for the free navigation and obstacle avoidance. The control system consists of a hierarchy of robot behaviors. The mobile behavior control system was based on the use of a number of Transputers processors. Behavior methodology was based on the utilization of a structure of a five layers Neuro-fuzzy system that learns, trains, and adapts itself to the environment.","PeriodicalId":161995,"journal":{"name":"2011 UkSim 13th International Conference on Computer Modelling and Simulation","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116407509","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}

According to the Portuguese law, every month or quarters, each certified accountant should send VAT information of the companies of its responsibility to the Government, using the official VAT form application. However, it is not possible for accounting students to train their abilities using this application, as it is for official use only. This constitutes a problem, because students can not learn and practice the \" real\" process. VAT Simulator provides students with the possibility of filling and submitting the VAT form just as a certified accountant does, \" learning by doing\".","PeriodicalId":161995,"journal":{"name":"2011 UkSim 13th International Conference on Computer Modelling and Simulation","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116422591","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}

Venkatesh","doi":"10.1109/UKSIM.2011.49","DOIUrl":"https://doi.org/10.1109/UKSIM.2011.49","url":null,"abstract":"This paper presents a novel and robust approach to detect and follow a human with a mobile robotic platform. In order to follow a human, both the initial detection of human and the subsequent tracking need to be implemented. As the robot is initially static, initial human detection is done using a background subtraction technique. To remove the outliers objects, filters are formulated based on the aspect ratio and horizontal projection histogram of the human. Human detection in subsequent frames is done by back-projecting the color histograms of the human torso and legs. To make the human detection robust, a shape analysis algorithm is developed to find the “two legs apart pattern” in the vertical projection histogram (VPH) of the detected foreground. For tracking, linear motion controllers are proposed: these require visual information to generate motion commands for the robot. The novelty of our approach includes (1) human tracking using visual information alone, (2) use of simple linear motion controllers to generate the translational and rotational velocities for the robot, and (3) cost effectiveness, as the experimental set up requires only one vision sensor. The current version of our system, runs on a Pioneer P3-DX mobile robot, and can follow human at up to 0.7m/s in an indoor environment.","PeriodicalId":161995,"journal":{"name":"2011 UkSim 13th International Conference on Computer Modelling and Simulation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123059088","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 computers with Windows operating systems were connected via a 100 Mbps link and for various payload sizes, ranging from 128 Bytes to 1408 Bytes, the TCP traffic on the link was measured using the various monitoring tools mentioned above. The results indicate that these tools can produce significantly different results. In the Windows environment, the bandwidth that the tools measure can vary as much as 16.5 Mbps for a TCP connection over a 100 Mbps link. For the same network set up, Iperf measured the highest bandwidth (93.1 Mbps) while IP traffic the lowest (76.7 Mbps).

How to reduce and make energy consumption more efficient in home environments has become of great interest for researchers. This could be achieved by introducing a Home Energy Management System (HEMS) into user residences. This system might allow the user to control the devices in the home network through an interface and apply energy management strategies to reduce and optimize their consumption. Furthermore, the number of devices and appliances found in users residences is increasing and these devices are usually manufactured by different producers and can use different communication technologies. This paper tackles this problem.

Therefore, in the occupancy signal generated by the simulator, both seasonality and trend are included in occupant's movements. As the result of trends integrated to the simulator, occupancy signals with different types of trends such as increasing, decreasing, cyclic and chaotic trends can be generated. Different types of the trend in occupancy signal improves the occupancy modelling by enabling the model to incorporate long term differentiation in occupant's behaviour i.e. ageing, health, and other changes in his/her activities of daily living. In this paper, the effect of trends in the occupancy signal generated by the modified simulator is tested by applying autocorrelation function.","PeriodicalId":161995,"journal":{"name":"2011 UkSim 13th International Conference on Computer Modelling and Simulation","volume":"140 21","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120820380","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 solar system is modelled and analysed in MATLAB/SIMULINK. The photovoltaic panel has an optimal operating voltage where the PV panel can produce maximum power at this particular point. Due to the nonlinearity of the voltage-current characteristic in solar panel, it is difficult to determine analytically the maximum power operating voltage that varies with the change of solar irradiance and cell temperature. Maximum power point tracking (MPPT) is implemented to identify the maximum power operating point, subsequently regulate the solar panel to operate at that particular operating voltage for maximum power gaining. Perturb and observe (P&O) MPPT and fuzzy based optimized P&O MPPT are developed and the performances of both controllers are examined at variable solar irradiances at different temperatures. Simulation results show that fuzzy based P&O MPPT has better performance where it can facilitate the solar panel to produce a more stable power.","PeriodicalId":161995,"journal":{"name":"2011 UkSim 13th International Conference on Computer Modelling and Simulation","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125323730","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}
