This paper presents two gait authentication features based on geometric shape for gait analysis. Specifically, triangle and trapezoid based features are proposed for gait authentication. The features are based on the geometric pattern extracted from a particular gait cycle of a gait model. These features use four points from hip-knee-toe joints and construct a triangle and a right trapezoid. The area of the triangle and trapezoid are calculated using geometric formula as well as image processing methods. Later two areas are compared to validate the model free approach. The results show that, the proposed feature can be used as the features in model free gait analysis.
提出了两种基于几何形状的步态认证特征,用于步态分析。具体来说,提出了基于三角形和梯形特征的步态认证方法。这些特征是基于从步态模型的特定步态周期中提取的几何图案。这些特征利用臀部-膝盖-脚趾关节的四个点,构造一个三角形和一个直角梯形。利用几何公式和图像处理方法计算三角形和梯形的面积。然后比较两个区域来验证无模型方法。结果表明,所提出的特征可以作为无模型步态分析的特征。

Vanadium dioxide (VO2) is a dark blue inorganic compound and excellent material with a high potential for smart window application due to its characteristic. A research to study the effect of different rotation per minutes (rpm) of spin coater on VO2 thin films was conducted. A suitable precursor was formed by mixed a vanadium oxytripropoxide with isopropanol into the clean beaker and mixed slowly. Part of the process, spin coater and heat treatment were used to form a thin layer of VO2 on ten pieces of quartz substrates by applied a standard operation set up. The samples then were characterized by Field Emission Scanning Electron Spectroscopy (FESEM) for thickness measurement via cross section process and surface morphology of the grains. The range of measured thickness and size of grain were 520nm to 1960nm and 300nm to 349nm respectively. The results shown that, the quality of the fabricated VO2 in terms of thickness and surface morphology were inversely proportional with rpm of the spin coater.
二氧化钒(VO2)是一种深蓝色无机化合物,由于其独特的特性,在智能窗户领域具有很高的应用潜力。研究了不同转速(rpm)的自旋镀膜机对VO2薄膜的影响。将氧三丙醇钒与异丙醇混合,在洁净烧杯中缓慢混合,形成合适的前驱体。采用标准操作装置,采用自旋涂布机和热处理,在10块石英衬底上形成一层薄薄的VO2。然后用场发射扫描电子能谱(FESEM)对样品进行了表征,通过截面工艺测量了样品的厚度,并对晶粒的表面形貌进行了表征。测得的晶粒厚度和尺寸范围分别为520nm ~ 1960nm和300nm ~ 349nm。结果表明,制备的VO2的厚度和表面形貌与旋转涂布机的转速成反比。

Traffic congestion in the city of Dhaka is reaching a new pinnacle every day. Owing to numerous private cars and local buses, the gridlocks in Dhaka city can be termed as one of the worst in the world. In a recent study done by Bangladesh University of Engineering and Technology(BUET) and Accident Research Institute (ARI), it was stated that around 5 million working hours are being lost every year in Dhaka city due to traffic gridlocks. This results in a loss of worth Tk.37,000 crore [1]. In order to resolve this issue and help manage the gargantuan problem, we decided to tackle this by the implementation of Kalman Filter in order to predict the level of congestion at a particular road according to time variance of the day. The reason for using Kalman Filter is because its accuracy. Other reasons being that it can be simulated using Matlab and can be constantly updated using the latest data.
达卡的交通拥堵每天都达到一个新的高峰。由于私家车和公共汽车众多,达卡的交通堵塞可以说是世界上最严重的交通堵塞之一。孟加拉国工程技术大学(BUET)和事故研究所(ARI)最近进行的一项研究表明,由于交通堵塞,达卡市每年损失约500万个工作小时。这导致了价值3700亿卢比的损失[1]。为了解决这个问题并帮助管理这个庞大的问题,我们决定通过卡尔曼滤波的实现来解决这个问题,以便根据一天的时间变化来预测特定道路的拥堵程度。使用卡尔曼滤波的原因在于它的精度。其他原因是它可以用Matlab进行模拟,并且可以使用最新的数据不断更新。

This paper proposes an alternate solution for easy communication by deaf and mute people. A device named Deaf-Vibe has been developed, which enables deaf and mute people to communicate rather easily with others using tactile senses and gestures. The device converts voice inputs by normal people to vibrotactile output in Morse code. In this method, the voice message is converted to text first and then to equivalent Morse code signals using a built-in Morse code conversion table. These signals drive vibration motors placed inside the fingers of a wearable glove. A deaf person wearing the glove senses the vibration in his or her fingers and understands the message. This device can also be used by a mute person to send messages by bending fingers in the Morse code sequence. The flex sensors placed within the glove fingers sense the finger movement and generate equivalent electrical signals which are then converted to text using a text-to-voice synthesizer to be finally pronounced and heard as audible messages. The resulting device is a simple, low-cost efficient and wearable solution which can be used by deaf and mute people in their everyday lives as an effective communication tool.
本文为聋哑人提供了一种方便交流的替代方案。一种名为deaf - vibe的设备已经开发出来,它使聋哑人能够很容易地通过触觉和手势与他人交流。该设备将正常人的声音输入转换为莫尔斯电码的振动触觉输出。在这种方法中,语音信息首先转换为文本,然后使用内置的莫尔斯电码转换表转换为等效的莫尔斯电码信号。这些信号驱动放置在可穿戴手套手指内的振动马达。戴上这种手套的聋哑人能感觉到手指的震动,并理解其中的信息。哑巴也可以用这种装置按莫尔斯电码序列弯曲手指来发送信息。放置在手套手指内的弯曲传感器感知手指的运动,并产生等效的电信号,然后通过文本-语音合成器将其转换为文本,最终作为可听信息被读出和听到。由此产生的设备是一种简单,低成本,高效,可穿戴的解决方案,可以作为聋哑人在日常生活中使用的有效沟通工具。

Asthma is a chronic disease that requires monitoring and treatment throughout the patient's lifetime. The common adventitious sounds related to asthma are wheezes. A study that has classified the severity of asthma using wheezes are still lacking in the field, therefore, the purpose of this work is to compare feature extraction methods for the classification of asthma severity level. Three types of features opted are mel frequency cepstral coefficients (MFCC); short time energy (STE); auto-regressive model and k-nearest neighbor (KNN) classifier is used in representing the performance of the feature used. Based on the overall performance between the features, MFCC features and KNN classifier shows the best and the highest performance with 95.92%, 96.33% and 98.42% average accuracy, sensitivity and specificity value obtained compared to STE that only obtained the highest average accuracy, sensitivity and specificity value of 84.94%, 87.33% and 95% respectively while AR features only obtained the highest average accuracy, sensitivity and specificity value of 49.43%, 52.17%, and 82.79% respectively.

In this paper, MIMO system is used to improve the performance of transmitted signal by reducing the signal fading rate. MIMO VBLAST technique is implemented to enhance the spectral efficiency and bandwidth with spatial diversity. Multiple antennas allowed the system to transmit multiple same data signal at the same time in which the data will not fade simultaneously, hence, improving the Signal to Noise Ratio (SNR) of the system. Zero Forcing (ZF) and Minimum Mean Square Error (MMSE) detection scheme are used to minimize the effect of channel estimation errors. The simulation was carried out in MATLAB software. Based on the simulation result, the proposed scheme for MIMO VBLAST has better network throughput in term of successful message delivery performance compared to the traditional scheme.

Hypertension prevalence around the world has risen over the last few years. The gulf countries has become one of the most affected countries in the world. Saudi Arabia only estimated that 24 % of the current population is suffering from hypertension. This has been attributed to elements such as lack of proper management systems for hypertension and inadequate education systems in the region. In addition to this health problem, gulf countries have increased its use of smart phones. The country's access to the internet has also increased. This paper analyses focuses on evaluating the need for educating and managing hypertension patients through social network and mobile health technology in gulf countries. Data was collected by the mixed-method design. The participants were between the ages of 20 and 40 years. The findings of the study showed that there is a need to develop a mobile technology system that enhances educational awareness for hypertension.
在过去几年中,世界各地的高血压患病率有所上升。海湾国家已成为世界上受影响最严重的国家之一。沙特阿拉伯仅估计24%的当前人口患有高血压。这是由于该区域缺乏适当的高血压管理系统和教育系统不足等因素造成的。除了这个健康问题,海湾国家也增加了智能手机的使用。该国的互联网接入也有所增加。本文分析的重点是评估海湾国家通过社交网络和移动医疗技术对高血压患者进行教育和管理的必要性。数据采用混合法设计。参与者的年龄在20到40岁之间。研究结果表明,有必要开发一种移动技术系统,以提高对高血压的教育意识。

Agarwood is a resinous heartwood and Aquilaria is one of many species that grows a lot in Asia. Traditionally, the quality of agarwood oil is based on color, odor, high fixative properties and consumer perception. This quality grading is performed by trained human graders using sensory panels. Human sensory panels has limitation such as fatigue. Therefore, this study focuses on chemical compounds of Agarwood oil. Using this compounds together with artificial intelligence technique, a new grading system will be proposed. This paper discusses only on the statistical analysis of the chemical compounds. 106 compounds were acquired using GC-MS analysis. To remove insignificant compounds, missing values ratio was computed and out of 109 only 19 compounds remained. These compounds were transformed using natural logarithm to improves the distribution of data.
沉香是一种树脂心材,沉香是亚洲大量生长的许多物种之一。传统上,沉香油的质量是基于颜色,气味,高固定性能和消费者的感知。这种质量分级是由训练有素的人类分级员使用感官面板进行的。人类的感觉面板有局限性,比如疲劳。因此,本研究的重点是沉香油的化学成分。将这些化合物与人工智能技术相结合,提出一种新的分级系统。本文只讨论化合物的统计分析。GC-MS分析得到106个化合物。为了去除不重要的化合物,计算缺失值比,109个化合物中只剩下19个化合物。使用自然对数对这些化合物进行变换,以改善数据的分布。

The conclusion and administration of gestational (diabetes with pregnant) are regularly a convoluted procedure. Late versatile wellbeing advances and information mining ideas are utilized as a part of upgrading constant maladies from a self-administration point of view, for instance, diabetes, and different examinations have demonstrated its proficiency. Further, explore has demonstrated that expanded attention to the infection encourages the diabetics to oversee successfully the illness and consequently limited the suggestions that emerge because of diabetes. This paper gives a presentation of innovative mobile management of gestational diabetes and the system of education the diabetics should be provided within Gulf countries. The displayed framework makes utilization of information mining in parallel with versatile wellbeing advances. The point of the framework is to enhance the gestational diabetes administration and to enable diabetics with significant information about illness self-administration to enhance their mindfulness about the ailment in Gulf nations. The proposed framework introduced in this paper will be tried and assessed widely in a randomized controlled preliminary in Saudi Arabia as a contextual investigation.
妊娠期(妊娠糖尿病)的诊断和管理通常是一个复杂的过程。从自我管理的角度来看,最近的多功能健康进步和信息挖掘思想被用作升级经常性疾病的一部分,例如糖尿病,不同的检查已经证明了它的熟练程度。此外,探索已经证明,扩大对感染的关注鼓励糖尿病患者成功地监督疾病,从而限制了因糖尿病而出现的建议。本文介绍了创新的流动管理妊娠糖尿病和教育系统的糖尿病患者应提供在海湾国家。所展示的框架利用信息挖掘与多种健康进步并行。该框架的重点是加强妊娠糖尿病管理,使糖尿病患者能够获得有关疾病自我管理的重要信息,以增强他们对海湾国家疾病的关注。本文提出的框架将在沙特阿拉伯作为背景调查的随机对照初步试验和广泛评估。
