Topographical map production is a tedious process, where it involves flight planning for the aerial photographic mission, preparation of ground control points, photogrammetric processes and cartographic activities. The task is time consuming, labour intensive and costly. With the vast development of the Klang Valley in Malaysia, customary revision of the topographic maps using the conventional method is expensive. At present, LiDAR (Light Detection and Ranging) technology is able to suffice accurate 3D (three dimensional : x, y, z) points of the earth surface in short delivery time. In this study, the possibility of LiDAR dataset (Digital Surface Model) as an important source of information towards topographic maps revision will be investigated. The study area comprises of an undulating topography situated at Melawati in the Klang Valley region, Malaysia, covering an area of one square kilometer. The accuracy of the derived LiDAR dataset both in vertical (RMSEz) and horizontal (RMSExy) components were quantified. Furthermore, the accuracy for the published topographic maps at the scale of 1:10 000 and 1:50 000 were also investigated in both components. The results obtained are then compared with the specification published by the Malaysian Map Accuracy Standards. It were found that, the vertical (RMSEz) accuracy achieved were ±0.21m, ±1.94m and ±6.88m for LiDAR dataset, topographic maps at the scale of 1:10 000 and 1:50 000 respectively. Where else, for the horizontal component (RMSExy), the accuracy estimates derived were found to be ±0.51m, ±1.33m and ±11.63m for the mentioned dataset respectively.
地形图的制作是一个繁琐的过程，它涉及航空摄影任务的飞行计划、地面控制点的准备、摄影测量过程和制图活动。这项任务耗时、劳力密集、成本高昂。随着马来西亚巴生山谷的巨大发展，使用传统方法对地形图进行习惯修订是昂贵的。目前，激光雷达(LiDAR, Light Detection and Ranging)技术能够在较短的交付时间内满足地球表面精确的3D(三维:x, y, z)点。在本研究中，将探讨激光雷达数据集(数字地表模型)作为地形图修订的重要信息来源的可能性。研究区域包括位于马来西亚巴生谷地区梅拉瓦提的起伏地形，面积为一平方公里。导出的LiDAR数据集在垂直(RMSEz)和水平(RMSExy)分量上的精度被量化。此外，还对已出版的1:10 000和1:50 000比例尺地形图的精度进行了研究。然后将所得结果与马来西亚地图精度标准公布的规范进行比较。结果表明，在1:10 000比例尺和1:50 000比例尺下，LiDAR数据集和地形图的垂直(RMSEz)精度分别为±0.21m、±1.94m和±6.88m。另外，对于水平分量(RMSExy)，得出的精度估计分别为±0.51m，±1.33m和±11.63m。

The usefulness of a simulation is determined by the validity and results of the simulation that can be used by a user to experiment with the system being simulated. In order to to develop a flexible simulator system with a long useful life, an abstraction needs to be introduced in the modeling and validation proses to separate it from the simulation engine itself. The aim is to develop an architecture that can separate the modeling proses of a simulation from the simulation engine that is being used. The language used to model the simulation is Modelica. The Modelica file is converted into the C programming language using tools provided from OpenModelica that is then integrated to the real-time simulator runtime developed in this thesis. This paper discusses the design and implementation of two different simulator architectures. These two architectures are the multi-threaded and non-threaded real-time simulator runtime. The conclusion of the testing and analysis done towards the two architectures is that the non-threaded architecture results in the most valid simulation producing simulation values closest to the real value and is able to fulfill the hard-real time requirements of the simulation.

Early flood alerts system is use to create a tool to measure water level, which powered by solar cell panel. The system is supported by microcontroller and GSM modem to send the measured data via SMS (Short Message Service) into two specific clients' phone numbers that have previously been inputted into the system. Besides the capability to predict the remaining time before the flood, this system can also detect three types of water level: early flood level, flood level and low tide level after the flood with a maximum water level detection of four meters. This system focused on an accurate measurement of the height of the water level and sending a warning message of the threshold height set before to the clients. For each of water level, the system will send three messages for each client number. The setting for client phone numbers and the water level can be programmed by sending the SMS that has been formatted in the system. The early flood alerts system is based on ATMEL AT89S51 microcontroller and the measurement of the water level is processed by ultrasonic HC-SR04.

Air temperature element variation is affected by environmental factors. Factors that influence air temperature element variation are called air temperature control. There are numbers environmental factors of air temperature element control and this study was investigated environmental factors of elevation, station's location, coastline and land use types. In this study multiple regression method was applied to explicate the contribution of environmental factors on air temperature element variation. Since air temperature data is in discrete points, therefore spatial interpolation analysis was used in producing continuous of this discrete data. In implementing spatial interpolation analysis, estimation error of T - T' data was used, where T is mean monthly air temperature and T' was estimated mean monthly mean air temperature from the developed multiple regression model. Analysis of cross validation was carried out to determine five measured of errors. Spatial interpolation analysis using main data of estimation error of T - T' produced reliable errors and consistent map for mean monthly mean air temperature element in Peninsular Malaysia.

DTN protocol can overcome network problems such as intermittent connectivity, long or variable delay, asymmetric data rates, and high error rates. TCP/IP protocol, a common network protocol currently used for the internet, cannot handle these problems. By using postfix and DTN2, we can build a DTN-based e-mail server that is capable of sending and receiving e-mails even the server is not continuously connected to a network. This also requires a new method to send and receive e-mails. Postfix is used for managing and processing e-mail users. DTN2 is used for processing e-mails into bundles and bundles into e-mails based on DTN protocol. This requires programs that integrate the postfix e-mail system with DTN2, implemented using bash shell and awk, for sending and receiving e-mail. The email system has been tested in the real condition using trains. The results show that the DTN based email system is working properly.

This paper examines manoeuvring track-keeping autopilot of a Liquefied Natural Gas (LNG) tanker hull form, which was fitted by fins while taking into account the ship bank interaction effects. A time domain simulation program including ship steering autopilot has been developed to study the manoeuvring track for full loading condition. The results of simulations show that the ship-bank interaction effects, fitting fins and enlarging rudder size have significant influence on the manoeuvring capability of the LNG ship in canal water.

In order to fulfill some tasks to reach a certain common goal, agents need to make sequence of decisions they have to perform as agroup. The decision is taken based on a selection mechanism of available actions. Choosing arbitrary action will lead to time and energy waste, since not all actions are even optimum. Agents need to decide not only which individual action that will lead to optimum performance, but also their joint actions. Applying reinforcement learning in the multiagent's learning process gives a sequence of optimum joint actions, which collaboration of agents based on this optimum joint actions guarantees the fastest time to reach their goal.

The dental panoramic radiography is one of dental imaging that used to visualize the entirety of the maxilla and mandible jaws on the one image planes. Although the direct digital panoramic radiography has been available, however film-based panoramic radiography is still used on the mostly dental clinic and laboratory in Indonesia. The quality of film-based image has significant limitation due to chemical processing and image enhancement cannot be done if required. Therefore, digitized film-based image to digital image was required to allow image enhancements in order to improve the interpretability quality of information in the image. Digitized film-based image is performed using a flatbed scanner on transmission and reflection mode. In this paper, the contrast quality of digital image that scanned using both mode is evaluated based on statistic image characteristic. The results showed that the quality of digitized image using transmission mode is better than using reflection mode. However, if direct digital imaging is used as a gold standard, image enhancement on digitized image is still required. Four methods, i.e. contrast stretching, HE, AHE, and CLAHE are used to attempt improve the quality digitized image. Evaluation of the preference image quality is performed based on objective criterion. The preference image quality for digitized panoramic image can be obtained by using image enhancement based on CLAHE-Rayleigh method, that indicated by the lowest value of mean, standard deviation, RMSE, and average difference and the higher value of NAE and SAE.

The preference image quality for digitized panoramic image can be obtained by using image enhancement based on CLAHE-Rayleigh method, that indicated by the lowest value of mean, standard deviation, RMSE, and average difference and the higher value of NAE and SAE.","PeriodicalId":325365,"journal":{"name":"2012 International Conference on System Engineering and Technology (ICSET)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128876227","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}
