Visually impaired or blind people are someone who lost their ability to see. They usually depend on guide cane or guide dog to assist them navigates their environment. However, guide cane requires the blind to scan the surrounding manually with their hand while guide dog is expensive and has a short life span. There are many researches on creating better navigation aid for blind people. Instead of using vibration or alarm to notify the distance of the obstacles, this research proposed the application of sound notification for the blind. This system is developed using MATLAB r2010a with the integrated webcam of the laptop and a laser pointer. The laser pointer acts as a reference point so that object's distance can be calculated from the captured image by the webcam. This system manages to calculate distance for any color of object under any level of brightness condition during day and night time. It also possesses human head movement ability to turn left and right, up and down. This system managed to detect the obstacles up to a distance of 432 centimeters, which is sufficient to prevent the blind from bumping into the obstacles. The calculated distance is then converted to sound in order to notify the blind how far the object is away from them.
视力受损或失明的人是失去视觉能力的人。他们通常依靠导盲杖或导盲犬来帮助他们在环境中导航。然而,导盲杖需要盲人用手手动扫描周围环境,而导盲犬价格昂贵且寿命短。有许多研究为盲人创造更好的导航设备。本研究提出了用声音通知盲人,而不是用振动或报警来通知障碍物的距离。本系统采用MATLAB r2010a开发,集成了笔记本电脑摄像头和激光笔。激光笔作为一个参考点,这样物体的距离就可以从网络摄像头捕获的图像中计算出来。该系统能够在白天和夜晚的任何亮度条件下计算物体的任何颜色的距离。它还拥有人类头部的运动能力,可以左右、上下转动。该系统探测到的障碍物最远可达432厘米,足以防止盲人撞到障碍物。计算出的距离然后被转换成声音,以便通知盲人物体离他们有多远。

A digital signal processor (DSP)-based cross-coupled intelligent complementary sliding mode control (ICSMC) system is proposed in this study for the synchronous control of a dual linear motors servo system. The dual linear motors servo system with two parallel permanent magnet linear synchronous motors (PMLSMs) is installed in a gantry position stage. The dynamic model of single-axis motion control system with a lumped uncertainty, which comprises parameter variations, external disturbances and nonlinear friction force, is introduced first. Then, to achieve an accurate trajectory tracking performance with robustness, a cross-coupled ICSMC is developed. In this approach, a Takagi-Sugeno-Kang type fuzzy neural network (TSKFNN) estimator with accurate approximation capability is implemented to estimate the lumped uncertainty. Moreover, since a cross-coupled technology is incorporated into the proposed intelligent control scheme for the gantry position stage, both the position tracking error and synchronous error of the dual linear motors will converge to zero simultaneously. Finally, some experimental results are illustrated to show the validity of the proposed control approach.
提出了一种基于数字信号处理器(DSP)的交叉耦合智能互补滑模控制(ICSMC)系统,用于双直线电机伺服系统的同步控制。采用两个并联永磁直线同步电机(PMLSMs)组成的双直线电机伺服系统安装在龙门定位台上。首先介绍了包含参数变化、外部干扰和非线性摩擦力的集总不确定性单轴运动控制系统的动力学模型。然后,为了实现精确的鲁棒跟踪性能,设计了交叉耦合ICSMC。该方法采用具有精确逼近能力的Takagi-Sugeno-Kang型模糊神经网络(TSKFNN)估计器来估计集总不确定性。此外,由于所提出的龙门位置台智能控制方案中引入了交叉耦合技术,使得双直线电机的位置跟踪误差和同步误差同时收敛于零。最后,通过实验验证了所提控制方法的有效性。

An interception study of man-made forest was carried out in Bukit Lagong Reserved Forest. Out of 18 rainfall event recorded, all 18 events produce throughfall but only 15 events with measured stemflow. Two plots of 20m × 20m each were established to measure the distribution of interception (gross rainfall, Pg, throughfall, Tf and stemflow, Sf) and identify the percentage of forest canopy cover over the plotted area. Hemispherical photography method using fisheye lens was applied to capture canopy cover image over the plots. The forest plots were occupied with mixed dipterocarp trees consist of two canopy levels with 90% to 98% of canopy cover. The range of interception loss for this study is 1% to 73% with average of 30% of total gross rainfall. The relationship between interception loss and gross rainfall show a moderate correlation with r2 values of 0.3002. The canopy cover does impose significant effect to the loss of rainfall interception. From point-correlation, the interception loss (%) is increase proportionally to the canopy cover (%) with r2 values of 0.4559.
在武吉拉贡自然保护区对人工森林进行了拦截研究。在记录的18个降雨事件中,所有18个事件都产生了通流,但只有15个事件测量了茎流。建立2个各为20m × 20m的样地,测量截留量(总降雨量Pg、穿透降雨量Tf和茎流Sf)的分布,并确定样地的森林冠层覆盖率。采用鱼眼镜头半球面摄影方法对样地进行了冠层覆盖图像的采集。森林样地由两个冠层组成的混合龙脑树占据,冠层盖度为90% ~ 98%。本研究的截流损失范围为1%至73%,平均为总降雨量的30%。截流损失与总降雨量呈中等相关关系,r2值为0.3002。冠层盖度对截留雨量的损失有显著影响。从点相关上看,截留损失(%)与冠层盖度(%)成正比增加,r2值为0.4559。

Recently, the numbers of cars have been increased collateral with the economic growth and the needs of living. Parking problem is one of the crucial problems that we have to face in the overcrowding area. Campus area faced the same problem where the parking spaces are very limited to the staff, students and visitors. Therefore, we proposed a basic mathematical model to make an improvement on the number of parking spaces as maximum as possible. We considered three types of parking designs which are perpendicular parking, parallel parking and diagonal (angle) parking where each design proposed a basic mathematical algorithm respectively. By comparing these three different designs, the most suitable design for certain area at Dataran Mawar, UiTM Shah Alam is identified and the maximum numbers of parking spaces are obtained when the selected designs are combined. These algorithms can be used as an alternative model in optimizing the parking spaces in other congested area.
近年来,随着经济的增长和生活的需要,汽车的数量也在增加。在人口拥挤的地区,停车问题是我们不得不面对的关键问题之一。校园区也面临着同样的问题,教职员工、学生和访客的停车位非常有限。因此,我们提出了一个基本的数学模型,以使停车位的数量尽可能多。我们考虑了垂直停车、平行停车和对角停车三种类型的停车设计,每种设计分别提出了一种基本的数学算法。通过比较这三种不同的设计,确定了最适合Dataran Mawar, UiTM Shah Alam某区域的设计,并将所选设计组合在一起获得最大停车位数量。这些算法可作为其他拥堵区域停车空间优化的备选模型。

Electronic banking channels are playing an increasingly significant role in the financial sector particularly with regards to online transactions. However, there are some segments of bank customers who prefer to conduct their banking transactions the tradition way because of security and trust aspects. No doubt for the younger generation who are technology savvy, the use of e-banking facilities are beneficial to them as time and effort are saved. But there is an increasing concern by the banks' administrators as not all the customers are into online banking and this study is significant because of the need to know the factors which contribute to the e-banking usage. Therefore, this study was proposed firstly to determine the highest contributor among computer self-efficacy, perceived usefulness, perceived ease of use and security with usage of e-banking. Then, the second objective is to study the relationship between computer self-efficacy and usage of e-banking facilities. Last but not least is to compare the level of perceived ease of use of e-banking facilities among genders. The researchers are using probability and non probability sampling technique as well as face-to-face method for distributing questionnaires to the respondents. From the findings of this study, it was found that computer self-efficacy is the highest contributor among the factors that lead to the usage of e-banking. Meanwhile, the other factors are also influencing towards the usage of e-banking facilities. This study has identified the factors which have a say can influence the urban dwellers in Shah Alam to utilize the e-banking facilities.
电子银行渠道在金融领域发挥着越来越重要的作用,特别是在网上交易方面。然而,由于安全和信任方面的原因,有一部分银行客户更喜欢用传统的方式进行银行交易。毫无疑问,对于精通科技的年轻一代来说,使用电子银行设施对他们是有益的,因为他们节省了时间和精力。但银行管理人员越来越担心,因为并非所有客户都使用网上银行,这项研究具有重要意义,因为需要了解影响电子银行使用的因素。因此,本研究首先提出要确定电脑自我效能、感知有用性、感知易用性和使用电子银行的安全性的最大贡献者。然后,第二个目标是研究计算机自我效能感与电子银行设施使用之间的关系。最后但并非最不重要的是比较不同性别对使用电子银行设施的感觉程度。研究人员采用了概率和非概率抽样技术以及面对面的方法对受访者进行问卷调查。本研究发现,在导致使用电子银行的因素中,电脑自我效能感的贡献最大。同时,其他因素也对电子银行设施的使用产生影响。本研究确定了影响沙阿南州城市居民使用电子银行设施的因素。

This paper proposed a modified procedure of fuzzy LinPrera by adapting the Centroid method to defuzzify the final results into crisp values that best represents the whole set of fuzzy numbers. It is known that average is not suitable to use as a defuzzification method because it cannot represent the whole set of the fuzzy numbers and not consider the height of the membership function. By utilization of Centroid method, the defuzzification of fuzzy numbers can be done efficiently and the ranking process can be easily carried out. This modified procedure is adapted to the selection of best study mode offered by Universiti Teknologi MARA (UiTM) for working people in order to demonstrate the calculations and obtain the final results. This study reveals that the Centroid method in Fuzzy LinPrera procedure is effective and suitable to use as an alternative tool in solving MCDM problems.
本文提出了一种改进模糊linprea的方法,采用质心法将最终结果去模糊化为最能代表整个模糊数集合的清晰值。由于平均值不能表示模糊数的全部集合,且不考虑隶属度函数的高度,因此不适合作为去模糊化方法。利用质心法可以有效地对模糊数进行去模糊化,便于进行排序。为了演示计算并获得最终结果,该修改程序适应了Universiti technologii MARA (UiTM)为工作人员提供的最佳学习模式的选择。研究表明,模糊linprea过程中的质心法是一种有效的、适合作为MCDM问题替代工具的方法。

In this work, extraction of the oleic acid from the palm pressed fiber using supercritical carbon dioxide was studied at conditions of temperatures from 313.15 to 353.15 K and at pressures from 60 to 120 bars. Residual fibers from palm oil production contain more than 5% of the palm oil, which is a good source of oleic acid. The activity coefficients for both of solvent and solute were predicted based on the universal functional activity coefficient (UNIFAC). The parameters such as adsorption, diffusion, solubility, and desorption were determined using mass transfer modeling; these parameters are necessary for the optimization and scale-up of a supercritical extraction unit.
在温度313.15 ~ 353.15 K,压力60 ~ 120 bar的条件下,研究了超临界二氧化碳对棕榈纤维中油酸的提取。棕榈油生产过程中残留的纤维含有超过5%的棕榈油,棕榈油是油酸的良好来源。根据通用官能团活度系数(UNIFAC)预测了溶剂和溶质的活度系数。采用传质模型确定吸附、扩散、溶解度、解吸等参数;这些参数对于超临界萃取装置的优化和放大是必要的。

The Antarctic Treaty 1959 is the body that governs the Antarctic continent which plays an important role of preserving Antarctica's pristine environment. The Antarctic Treaty utilizes several environmental agreements namely Madrid Protocol to minimize the negative impacts of activities in the icy continent. Malaysia has been continuously expanding the Antarctic based research executed by local scientists since 1980s. Furthermore, Malaysia has officially joined the force in preserving the Antarctica's environment in 2011 by acceding the Antarctic Treaty and the Madrid Protocol. Thus, persistent efforts have been carried out in developing Malaysia's Antarctic Act to comply with both the Antarctic Treaty and the Madrid Protocol.
1959年的《南极条约》是管理南极大陆的机构,它在保护南极洲的原始环境方面发挥着重要作用。《南极条约》利用若干环境协定,即《马德里议定书》,尽量减少在这片冰冷大陆上活动的负面影响。自20世纪80年代以来,马来西亚一直在不断扩大由当地科学家进行的南极研究。此外,马来西亚于2011年正式加入了保护南极环境的力量,加入了《南极条约》和《马德里议定书》。因此,马来西亚在制定《南极法》方面作出了不懈的努力,以符合《南极条约》和《马德里议定书》。

Access control is a system which enables the authority to control and restrict access to a target sensitive or secured area. However, its effectiveness is highly dependent on the proper usage of the system by those who are granted access. These authorized personnel have total control of the door from the time it unlocks until it relocks again. One of the biggest weaknesses of automated access control is the lacked of a system to prevent a practice known as “tailgating” or “piggybacking”. This paper presents a low cost solution to this problem by using a single internet protocol camera and an embedded based control unit combining with video analytics technology. Results showed that the developed system is able to detect various tailgating/piggybacking violations successfully.
访问控制是一种系统,它使当局能够控制和限制对目标敏感或安全区域的访问。然而,它的有效性高度依赖于被授予访问权限的人对系统的正确使用。这些被授权的人员可以完全控制大门,从打开到再次锁上。自动访问控制的最大弱点之一是缺乏一个系统来防止所谓的“尾随”或“搭便车”行为。本文提出了一种低成本的解决方案,即使用单个网络协议摄像机和嵌入式控制单元,并结合视频分析技术。结果表明,所开发的系统能够成功检测各种尾随/搭便车违规行为。
