An Assistive Hand Glove for Hearing and Speech Impaired Persons 一种听觉及言语障碍人士的辅助手套
Marvin S. Verdadero, J. D. dela Cruz
Communication is more than spoken language; it is a way of expressing ones thought, ideas and messages. Communication for them has become a great challenge especially the need to communicate with normal people in their daily routine. Hearing/Speech Impaired persons used hand sign language as their language of communication; however, it will only be effective if the person they are interacting with knew the hand sign language. This study developed an assistive device for persons with hearing/speech impairment. The system was designed to interpret their signs or gesture into a corresponding message which were preloaded in the device. The device produced a voice-based message through the audio module and displays the message in LCD. This study was basically a glove based system and a microcontroller based system. Flex sensors, Gyroscope and Accelerometer were incorporated in a glove that can identify the sign language and an Arduino Nano microcontroller unit converted these gestures into voice and text output. The result of the Assistive device during its test-experiments showed that the system can recognized the hand gestures with male and female voice output on each hand gesture with an overall accuracy of recognition of 83.58%.
交流不仅仅是口头语言;它是一种表达思想、观点和信息的方式。沟通对他们来说已经成为一个巨大的挑战,特别是在日常生活中需要与正常人交流。听觉/言语受损人士以手语作为沟通语言;然而,只有在与他们交流的人知道手语的情况下,它才会有效。本研究开发了一种听觉/语言障碍人士的辅助装置。该系统被设计成将他们的手势或手势翻译成相应的信息,并预装在设备中。该设备通过音频模块产生语音信息,并在LCD上显示。这项研究基本上是一个基于手套的系统和一个基于微控制器的系统。Flex传感器、陀螺仪和加速度计被集成在手套中,可以识别手语,Arduino Nano微控制器单元将这些手势转换为语音和文本输出。辅助装置在测试实验中的结果表明,系统可以识别每个手势上有男声和女声输出的手势,总体识别准确率为83.58%。

Instrumentation of Raman Spectrometry for Acquisition of Molecular Vibration Structure 用于分子振动结构采集的拉曼光谱仪器
J. Lazaro, J. D. dela Cruz, J. Villaverde
Determining the structure of an organic compound are mainly based on the physical and chemical properties, because molecules are so small it is so hard to determine the molecular structure of a compound. In this study, a simple spectrometer is developed through instrumentation and control to perform acquisition of the molecular vibrations and determine the Raman shift in wavenumber of a sample. Because the vibration phenomenon of a molecular bond can be investigated under the Raman spectrum, a charged coupled device (CCD) was used in the instrumentation together with a diffraction grating of 1000lines/mm. The spectrometer built using a charged coupled device (CCD) array is capable of detecting ultra-violet, visible, and near-infrared spectrum. In the near-infrared region the identifying marks of the samples is recorded with energy spectral density that describes the optical wavelength and peaks in the IR spectrum. Using the reaction in the saccharomyces cerevisiae in water, the energy spectral density is monitored and shows that 81.52% of light is absorbed by the given sample during the reaction with wavenumber of 605.75cm-1 which suggest that the molecular vibration is occurring at the fingerprint region under the vibrational spectrum, and light absorption becomes weaker as saccharomyces cerevisiae stop producing carbon dioxide in water with 8.39% but with traces of chemical compounds at 623.14cm-1 Raman shift in wavenumber.
确定有机化合物的结构主要是根据其物理和化学性质,因为分子很小,所以很难确定化合物的分子结构。在本研究中,通过仪器和控制开发了一种简单的光谱仪,用于采集分子振动并确定样品的拉曼波数移位。由于在拉曼光谱下可以研究分子键的振动现象,因此在仪器中使用了电荷耦合器件(CCD)和1000线/mm的衍射光栅。利用电荷耦合器件(CCD)阵列构建的光谱仪能够探测紫外线、可见光和近红外光谱。在近红外区域,样品的识别标记用描述红外光谱中的光波长和峰的能谱密度记录。利用在水中进行的酿酒酵母反应,对能量谱密度进行了监测,结果表明,在反应过程中,给定样品吸收了81.52%的光,波数为605.75cm-1,表明在振动谱下的指纹区发生了分子振动。在拉曼波数为623.14cm-1时,当酿酒酵母停止在水中产生8.39%的二氧化碳,但仍有微量化合物时,其对光的吸收变弱。

E. Fernandez, Jonalyn E. Escosio, Romeo L. Jorda, Michelle Tamase, J. C. Puno, Louiejim Hernandez, August C. Thio-ac, Mark B. Cruz, Camille V. Lumogdang, Eddieson Real
The farmers and vendors in the Philippines classify coconuts through knocking manually either by bare hands or knife as 'mala-uhog', 'mala-kanin' and 'mala-tenga’. The said technique is well-known but yet carries no scientific proof. Thus, the proponents conducted this study to develop a knocking device that automatically classify coconuts by characterizing its maturity according to meat thickness and peak frequency using Fast Fourier Transform (FFT) algorithm. Sixty coconuts were sampled; each being initially categorized by a ‘mangangatok’ to the stage it belongs using the conventional method. Each were knocked using a knife at a constant distance and then opened right after for the measurement of its meat thickness using a Vernier Caliper. The recorded sounds were then analyzed using FFT Algorithm in OCTAVE. Statistical analysis show that each of the three stages has high correlation between 0.869 and 0.897 in terms of meat thickness versus peak frequency. Results showed that ‘malauhog’ coconuts have peak frequency range of about 200 to 400 Hz, 400 to 600 Hz for ‘malakanin’ and 600 to 800 Hz for ‘malatenga’. From these results, a standalone Arduino-based sound acquisition knocking device was developed. The Sound acquisition system is designed to be portable. Its functionality was tested by sampling 119 random coconuts. Results showed that out of 119 there were 10 errors made by the device, exhibiting 91.6% accuracy. The device has capabilities of classifying maturity stages of coconuts which provides efficiency for vendors and compatibility for consumers with no knowledge in the currently known method.
菲律宾的农民和商贩通过徒手或用刀敲打椰子,将椰子分为“mala-uhog”、“mala-kanin”和“mala-tenga”。上述技术众所周知,但没有科学依据。因此,支持者进行了这项研究,开发了一种敲击装置,该装置使用快速傅里叶变换(FFT)算法,根据果肉厚度和峰值频率特征,自动对椰子进行成熟度分类。60个椰子被取样;每个人最初都被“manggangatok”分类到它所属的阶段,使用传统方法。每个都是用刀子在固定的距离上敲击,然后马上打开,用游标卡尺测量肉的厚度。然后使用FFT算法在OCTAVE中对录制的声音进行分析。统计分析表明,3个阶段的肉厚与峰值频率的相关系数均在0.869 ~ 0.897之间。结果表明,“malauhog”椰子的峰值频率范围约为200至400赫兹,“malakanin”为400至600赫兹,“malatenga”为600至800赫兹。根据这些结果,开发了一个独立的基于arduino的声音采集敲打设备。声音采集系统被设计成便携的。它的功能是通过随机抽样119个椰子来测试的。结果显示,在119次测试中,该设备产生了10次错误,准确率为91.6%。该设备具有对椰子成熟阶段进行分类的能力,这为供应商提供了效率,并为不了解目前已知方法的消费者提供了兼容性。

CMOS Modified Differential Voltage Multiplier Co-integrated with Indoor Photovoltaic Energy Harvesting in 65nm CMOS Process for WSN Application CMOS改进差分电压乘法器与65nm CMOS工艺室内光伏能量收集协集成应用于WSN
Re-Ann Cristine O. Calimpusan, J. Hora, A. Lowaton
This circuit design presents a CMOS Modified Differential Voltage Multiplier co-integrated with indoor photovoltaic energy harvesting circuit for Wireless Sensor Node device in 65nm CMOS process. This work aims to supply power in Microsemi’s ZL70250, a wireless sensor network transceiver. Extraction of high DC voltage from rectifier block is always a serious bottleneck for energy harvesting. Consequently in this work, a simple mechanism to eliminate (Vth) of the MOS transistor by adding an auxiliary Pmos is proposed. Also, an additional capacitor (Cs) has been split into two capacitors that have been connected to the differential output. For analysis and comparison, the traditional and proposed voltage multiplier circuit is simulated and implemented with 3 stages with load capacitance of 100pF. The proposed voltage multiplier obtains a higher voltage conversion ratio (Gv) of 3.96, much higher than the reference voltage multiplier. The Gv and the generated boosted rectifier output voltage was obtained from 0.5V single PV. The modified architecture is integrated in indoor photovoltaic energy harvesting circuit. Accordingly, with this modification and implementation, this work able to supply power for Microsemi’s ZL70250 that requires 1.2V to 1.8V and less than 1.9mA to operate.
本电路设计提出了一种采用65nm CMOS工艺的CMOS改进差分电压乘法器与室内光伏能量收集电路协集成的无线传感器节点器件。这项工作旨在为Microsemi的无线传感器网络收发器ZL70250供电。从整流块中提取高直流电压一直是能量收集的一个严重瓶颈。因此,在这项工作中,提出了一种简单的机制,通过增加一个辅助的Pmos来消除(Vth)的MOS晶体管。另外,一个额外的电容器(Cs)已被分成两个电容器,已连接到差分输出。为了进行分析和比较,本文采用负载电容为100pF的3级电压倍增器电路进行了仿真和实现。该电压倍增器的电压转换比(Gv)为3.96,远高于参考电压倍增器。Gv和产生的升压整流器输出电压由0.5V的单个PV获得。改造后的建筑集成在室内光伏能量收集电路中。因此,通过这种修改和实现,该工作能够为Microsemi的ZL70250供电,要求1.2V至1.8V,小于1.9mA才能工作。

J. C. Puno, R. Bedruz, Allysa Kate M. Brillantes, R. R. Vicerra, A. Bandala, E. Dadios
Genetic Algorithm is the method used in this study in classifying the qualitative level of the soil nutrients. The data set includes images coming from the result of the soil testing. The extracted features were the HSV values and the LAB values color space. Out of the six extracted features from the data set, the B from LAB color space is the most linear so with that, it is the input of genetic algorithm in identifying the qualitative level of the soil nutrients. For the run of the program using python programming language and pyCharm CE as IDE, the values of each parameters follow: the population size is 10, mutation rate is 0.01, the number of cross over points is 2 and the maximum number of generations is 1000. The population’s final best fitness has 98.2609% that proves that Genetic Algorithm is an effective method in classifying the qualitative level of the soil nutrients.

Developing a Computer-Aided Pangasinense Language Learning System 计算机辅助Pangasinense语言学习系统的开发
Juan Miguel H. Villarroel, Jomar B. Calauod, M. Grande, King Harold A. Recto, Ronald M. Pascual
Ideally, instruction is best done one on one. However, due to the scarcity of public school teachers, this ideal remains just that, only an ideal. This ideal, however, can be realized by using a computer-assisted language learning system. One such language that this system can be applied to is the Pangasinense - one of the top ten languages of the Philippines. Using this system, any Filipino can now learn Pangasinense. Creating this involves developing the speech corpus for the Pangasinense language and designing a reading miscue detector (RMD) that employs hidden markov models (HMM) and artificial neural network (ANN). The RMD uses the reference verification (RV) method that compares the input speech to the reference speech found in the Pangasinense speech corpus. The collection of the speech corpus involved 10 native Pangasinense speakers who each recorded a total of 21 phrases and 309 words that were considered as common conversational phrases or words for Pangasinense. The system was initially tested by 10 native Pangasinense speakers, who also speak Filipino, and their scores were set as the reference scores. The system was then put to test by conducting a six-week pilot study participated by 10 Filipino speakers. The system’s effectiveness was then evaluated through the progress trends of all learners’ scores for each module. All learners’ progress curves showed to have a positive slope. In addition, the system’s efficiency was determined by its false alarm rate (FAR), misdetection rate (MdR), and accuracy. The system was able to get a FAR of 26.67% and 30%, MdR of 30.0% and 6.67%, and accuracy of 71.66% and 81.67%, for males and females group, respectively.
理想情况下,教学最好是一对一的。然而,由于公立学校教师的稀缺,这种理想仍然只是一种理想。然而,这一理想可以通过使用计算机辅助语言学习系统来实现。该系统可以应用的一种语言是Pangasinense -菲律宾十大语言之一。使用这个系统,任何菲律宾人现在都可以学习Pangasinense。创建这种语言包括为Pangasinense语言开发语音语料库,并设计一个使用隐马尔可夫模型(HMM)和人工神经网络(ANN)的阅读错误检测器(RMD)。RMD使用参考验证(RV)方法,将输入语音与Pangasinense语音语料库中的参考语音进行比较。语言语料库的收集涉及10位母语为pangasinese语的人,他们每人记录了21个短语和309个被认为是pangasinese语的常用会话短语或单词。该系统最初由10名母语为Pangasinense的人进行测试,他们也会说菲律宾语,他们的分数被设置为参考分数。然后,该系统进行了为期六周的试点研究,由10名说菲律宾语的人参加。然后通过所有学习者在每个模块的分数的进步趋势来评估系统的有效性。所有学习者的学习进度曲线均呈现正斜率。此外,系统的效率还取决于其虚警率(FAR)、误检率(MdR)和准确率。该系统在男性组和女性组的FAR分别为26.67%和30%,MdR分别为30.0%和6.67%,准确率分别为71.66%和81.67%。

Joseph Bryan G. Ibarra, Meo Vincent Caya, A. Paglinawan, Jerry Turingan, Sarah Alma P. Bentir, Jim Joseph Monta, Jumarie Mocon, A. Yumang, L. Sabino, M. Teogangco
The influence of technology in the evolution of modern-day education grows significantly as more educational institutions attempt to improve the quality of education. This study aims to develop a hybrid of a classroom response system and learning management system web and android applications without the use of the internet. A technology-needs assessment (TNA) was administered on 213 high school students. The TNA questionnaire was comprised by 16 closed-ended questions, 15 of which required Likert scale-based responses and one required a yes/no response. The TNA data was analyzed with the help of principal component analysis (PCA). The results of the PCA became the basis for the configuration of a wireless local area network of devices connected to a central server through a wireless router dedicated for the implementation of the web and android applications designed for the needs identified by the study. The web and android applications were developed using a test-driven development (TDD) approach. The system configuration was based on the system capacity requirements to enable simultaneous wireless connection of up to 100 mobile devices. Two groups of high school students were identified by the school to be part of the field testing of the web/android app since these students were of significantly similar academic standing in their respective classes. The study group (n=7) used the web/android app in their statistics class and a control group (n=10) were subjected to the traditional classroom set-up. The field testing lasted for two weeks covering various teaching and learning activities including exams. The exam results were subjected to Analysis of Variance using two-sample F-test and t-test. The results show that at 5% significance level, a p-value of 0.0026 was obtained, which indicates that the means between the summative test results data sets are significantly different. The performance of the students in the study group is significantly different from the performance of the students in the control group in the summative test. As observed in the summative test mean scores of the groups, the study group showed significant improvement in their performance when compared to the control group.
随着越来越多的教育机构试图提高教育质量,技术在现代教育演变中的影响日益显著。本研究旨在开发一个混合的课堂响应系统和学习管理系统的网络和android应用程序,而不使用互联网。对213名高中生进行技术需求评估。TNA问卷由16个封闭式问题组成,其中15个需要基于李克特量表的回答,1个需要回答是/否。采用主成分分析(PCA)对TNA数据进行分析。PCA的结果成为配置无线局域网的基础,该网络的设备通过无线路由器连接到中央服务器,该无线路由器专门用于实现为研究确定的需求而设计的web和android应用程序。web和android应用程序是使用测试驱动开发(TDD)方法开发的。该系统配置基于系统容量要求,可同时实现多达100个移动设备的无线连接。学校确定了两组高中学生作为web/android应用程序现场测试的一部分,因为这些学生在各自班级的学术地位非常相似。研究组(n=7)在统计学课堂上使用web/android应用程序,对照组(n=10)使用传统的课堂设置。现场测试为期两周,涵盖了包括考试在内的各种教学活动。检验结果采用双样本f检验和t检验进行方差分析。结果表明,在5%显著性水平下,p值为0.0026,表明总结性检验结果数据集之间的均值存在显著性差异。研究组学生在总结性测试中的表现与对照组学生有显著差异。从各组的总结性测试平均分中可以看出,与对照组相比,研究组的成绩有了显著的提高。

Design and Evaluation of a Mango Solar Dryer with Thermal Energy Storage and Recirculated Air 芒果太阳能蓄热循环空气干燥机的设计与评价
Kyle Jericho Grecia, Antoine Albert Luce, Matthew Adrian Buenaventura, A. Ubando, Ivan Henderson Gue
Climate change has drastically affected our production patterns, negatively distressing the yearly agricultural produce. A core process in the industry is the drying of biomass. Drying increases the value and extends the shelf life of the agricultural products. However, modern drying technologies are still reliant on fossil fuels. Solar-based drying technologies are needed to counteract the fossil fuel dependence. Other than reduction of fuel consumption, solar dryers are easily adaptable to rural communities with heavy reliance on the drying process. Alternative designs have been proposed to improve the performance of the solar dryers, notably integrating thermal energy storage (TES) systems. A limiting factor, however, is that the performance is constrained to the heating capacity of the TES. Previous study has examined the integration of TES with air recirculation, indicating an improved performance. Further evaluation of the dryer with another biomass is needed to illustrate the adaptability of the hybrid feature. This study, therefore, evaluates the performance of solar drying with TES and air recirculation for mango drying. Comparisons were made with other design combinations as a benchmark. Results reveal that the hybrid solar dryer can reduce the drying time from 7.17 hours to 5.32 hours.
气候变化极大地影响了我们的生产模式,给每年的农产品带来了负面影响。该行业的一个核心过程是生物质的干燥。干燥增加了农产品的价值,延长了农产品的保质期。然而,现代干燥技术仍然依赖于化石燃料。需要太阳能干燥技术来抵消对化石燃料的依赖。除了减少燃料消耗外,太阳能干燥机很容易适应严重依赖干燥过程的农村社区。已经提出了替代设计,以提高太阳能干燥器的性能,特别是集成热能储存(TES)系统。然而,一个限制因素是性能受限于TES的供热能力。先前的研究考察了将TES与空气再循环系统相结合,表明性能有所改善。需要进一步评估干燥器与另一种生物质,以说明混合特性的适应性。因此,本研究评估了TES和空气循环太阳能干燥对芒果干燥的性能。与其他设计组合进行比较作为基准。结果表明,混合太阳能干燥机可将干燥时间从7.17 h缩短至5.32 h。

A Fuzzy Logic-Based Stock Market Trading Algorithm Using Bollinger Bands 基于模糊逻辑的布林带股票交易算法
Sandy C. Lauguico, R. Ii, Jonnel D. Alejandrino, Dailyne D. Macasaet, Rogelio Ruzcko Tobias, A. Bandala, E. Dadios
Stock market price forecasting with the use of Technical Analysis is not precise Mathematics. Mostly, prediction is only based on probabilities supported by historical data and patterns. With these, several technical strategies were made by traders to produce signals on trading execution. This study proposes an algorithm that undergoes a certain trading strategy using three fuzzy logic controllers. Technical indicators such as candlestick parameters and Bollinger Bands (BB) were used for triggering the strength of buy, hold, and sell signals. Stock price data were gathered from a certain stock company. These data contain the opening and closing prices that are utilized for computing the BB. The raw and the computed values are the crisp input parameters for the Fuzzy Inference System (FIS). The membership functions were classified to very low, low, high, and very high levels depending on the input default parameters used by traders. Sets of rules were created fuzzy logically to produce signals indicating the strength of an execution recommendation. The system is implemented using NI LabVIEW and MATLAB, proving that the tests are yielding acceptable result of about 94.44%.

Development of Smart Waste Bin with Integrated Volume and Weight Sensor 集成体积重量传感器的智能垃圾箱的研制
J. M. U. Aguila, H. Dimayuga, K. Pineda, G. Magwili
Solid waste is a problem that keeps on increasing as the population of a country grows. Proper waste management is one solution which would help maintain our green environment. Since production increases the consumption in urban areas has also increased in the quantity of wastes generated. This paper presents a solution wherein waste management can be monitored in real time to keep track of the capacity of the bins in the vicinity using the application created by the researchers in order to assist local government of proper waste management. The proposed system will alert the municipality through the application when the measured waste level is at a certain point. The proposed system consists of ultrasonic sensor to measure the volume of the bins, the load cell to measure the weight of the bin, and an Arduino Uno which controls the system operation. As soon as it reaches a certain point the arduino will send a notification to the person in charge, so that the waste can be collected immediately.
