Pulse width modulation has many useful applications and so with this, a PWM signal simulation through MATLAB is presented that can be beneficial for analysis and model development. This paper aims to have a baseline how to present pulse width modulation graphically using MATLAB. The specific design has a graphical user interface window to display the generated pulse width modulation signal and modulating signal in which user can indicate sampling frequency to be used and the information signal. This module can be also later used for circuits or networks that need control or switching.

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. Since it is the most used pump in the world, then it must be improved now and then. The rotational energy typically comes from an engine or electric motor. This study was performed to investigate the effects of changing the number of impeller blades in the Head and the Efficiency of the pump running at constant and varying speeds. The researchers were able to provide a pump performance curve for 4, 5, 6, and 7 blades running at 2300 RPM, 2800 RPM, and 3300 RPM. It is shown in the results that utilizing the researcher’s centrifugal pump model with 7 impeller blades running at 3300 RPM is the most ideal and suitable operation.

Facial expression recognition is one of the most significant aspect of our life at all levels. Realizing the impact of this feature to our society, this project hence developed a driver’s fatigue and drowsy detection system to detect a fatigue driver while driving a car. Present trends had suggested that driving and navigation support systems are getting much importance today as it has become a crucial element to support drivers in various aspects within the automobile industry. Hence, this system is important for driving support systems to detect the status or activity of driver’s consciousness. The methodology development that used in this system is Waterfall Methodology model, where each phase is important to achieving the goals of the project. Each phase in this Waterfall model is important for reaching the requirement of clients and accomplish the goal of the project. Basically, this system assists the driver and calculate the state of behaviour according to the driver face. Moreover, once the measurement process has been carried out by OpenCV Python, this application would instantly provide immediate alert sound to the driver through this application. Anaconda is an environment to create and implement an algorithm to detect yawn and drowsy. The system has been tested and managed to detect fatigue and drowsy then sent alert to driver. Thus, hopefully this system can prevent and reduce the number of road accidents caused by sleepy drivers. In addition, this system might save countless lives in Malaysia. Technology Acceptance Model (TAM) was being used to gather feedback in a form of questionnaires that were distributed online, where maximum number of 87 responses were successfully gathered.

Mango pulp weevil (MPW) behavior has been long studied but frequency characterization of the said pest in different adult activities was not yet explored. This study focused on the comparative classification of the mating activity of the MPW. Data was collected on a controlled environment with an acoustic chamber built, and the frequency was acquired using a MEMS (Micro Electro-Mechanical Systems) microphone, connected through a microcontroller. Two different algorithms namely the Decision Tree Learning algorithm and Naïve Bayes Classifier algorithm, were tested and compared. Performance in the filtering and optimization of the two algorithms were evaluated in three different stages of mating, the pre-mating, mating and post-mating stage. Comparison of the results of the two algorithms for the premating stage, the Decision tree algorithm reached 75% accuracy while Naïve Bayes algorithm had 95% accuracy, for the mating stage, it was 55% as compared to 70% and in post mating stage, 45% accuracy for the Decision Tree Learning algorithm and 85% for the Naïve Bayes algorithm. These results showed that Naïve Bayes classifier is more accurate in classifying the different stages of MPW activity.

Skim Pinjaman Buku Teks (SPBT) is a textbook loan program for elementary and secondary schools in Malaysia. This program is an initiative system by the Malaysia Ministry of Education to help students in the school by providing them with textbooks for their learning purpose. The current SPBT system is handled by storing all the records into a book or a file that can cause data missing, data redundant and incorrect data stored in the system. This project presents a new system for the textbook loan system known as Smart Skim Pinjaman Buku Teks (SBPT) School Operation system (SSSOS). This system upgrades the conventional method that manually records the loan information to a systematic approach using a web-based management system. The rapid application development (RAD) cycle is used as a methodology to develop the SSSOS system. The proposed system can efficiently handle borrowing and returning processes and reduce the textbook loan process period. This system also provides a complete report related to the textbook, such as the current status of a book and the previous information of the borrower. The proposed system can be used to enhance the conventional SPBT system in handling the textbook loan program. The system has been tested in Sekolah Kebangsaan Gambang, Pahang, where an SPBT coordinator acts as a client for the system.
skimpinjaman Buku Teks (SPBT)是马来西亚小学和中学的教科书贷款计划。该计划是马来西亚教育部的一个倡议系统，旨在帮助学校的学生，为他们提供学习目的的教科书。目前的SPBT系统是通过将所有记录存储到一个本子或文件中来处理的，这可能导致系统中存储的数据丢失、数据冗余和不正确的数据。本项目提出了一个名为Smart Skim Pinjaman Buku Teks (SBPT)学校运营系统(SSSOS)的教科书借阅系统新系统。该系统将传统的手工记录贷款信息的方法升级为基于web的系统化管理系统。采用快速应用程序开发周期(RAD)作为开发SSSOS系统的方法。该系统能够有效地处理图书借阅和还书流程，缩短了图书借阅流程周期。该系统还提供了与教科书相关的完整报告，例如书籍的当前状态和借阅者的以前信息。该系统可用于改进传统的SPBT系统在处理教科书借阅程序方面的功能。该系统已在彭亨州的Sekolah Kebangsaan Gambang进行了测试，在那里，SPBT协调员作为该系统的客户。

With the unprecedented impact of the Covid-19 Pandemic on the education sector on a global scale, different countries and their respective governing bodies devised tools to minimize the interruptions on the educational system. Using online learning technology as an alternative is greatly practiced to lessen physical contact that can worsen the transmission of the virus. This paper explores, study and investigates the students’ acceptance of online learning technology as an alternative in implementing and facilitating the learning curriculum during the pandemic in a developing country like the Philippines. The study employed Technology Acceptance Model and survey forms were distributed among private and public HEI students online. Results suggest that students strongly agree that online learning technology is acceptable but with some concerns on complexity. These complexities can be attributed to the implementation of laboratory courses online and the capacity of devices required by the Online learning tools to be utilized by different HEIS. This study addresses research limitations with theoretical and practical implications that could be used in policymaking, guideline development regarding the implementing Rules and Regulations of HEI as well as the acquisition of materials for online learning.

The solar-powered evaporative cooling system is designed to be mounted in a car’s window for lowering the temperature inside, as the car experiences too much heat when exposed for a long time under the sun. Evaporative coolers work by changing hot air into a cool temperature by evaporating water into the air. The system operates with the solar panel powering the battery and the battery runs the components of the system. The researchers conducted the testing of the system in a Class 1 type of vehicle. Two vehicles were placed in a parking lot wherein one has the system and the other one does not. With the use of a thermometer and hygrometer, the temperature and relative humidity were both measured and used to have a comparison between the two cases to evaluate the performance of the system. The system was able to reduce the temperature build-up inside the vehicle on its different parts, while the inside relative humidity increased. The temperature drop was very significant since, without the system, the highest temperature recorded inside the car was 47 °C while the ambient temperature was at 37 °C. With the use of the system, the inside cabin temperature was able to decrease by 12 °C but the relative humidity is 62%. Although the rise in relative humidity was comparably low to the ambient relative humidity which is 60%, it is still ideal that the relative humidity must be low that is why dehumidifiers should be used. With the testing done, the system was able to reject 0.3251 kW of heat in which its achieved COP is 7.5.

This paper presents a tuning constraint optimization approach in state feedback controller for liquid slosh suppression system. A suboptimal LQR method is employed to obtain the optimal gain parameters in minimizing the selected cost function. Due to complexity of the nonlinear slosh system, a partial linearization method was first performed to obtain its linear state space representation. Due to the presence of the large steady-state error caused by the implementation of only the state feedback gains, an additional integral term has also been introduced to mitigate its effects. A comparative assessment on the system performance is investigated between regular LQR and LQR-LMI control algorithms. The presented results indicated that the LQR-LMI exhibited better transient response performance as compared to the regular LQR for the case of moving the cart to its intended final position while ensuring the slosh motion is suppressed to a minimum angle.

Edible Bird Nest (EBN) produced by certain species of swiftlets has been known of its source of protein and vitamins that benefit the human body. This results in high demand from humanity due to the advantages of consuming the EBN. However, manual process of grading and classifying the EBN for different price range may cause drawbacks towards the production of EBN. The grading of EBN is done by observing the colour, shape, size and impurities present in the nest. Although manual process is done by trained personnel, the results obtained are often inconsistent and inaccurate due to human fatigue. Hence, this process is tedious and time consuming which may cause delay in the production of EBN. To overcome this issue, a novel Drunken Flower Pollination Algorithm (DFPA) is developed to perform auto grading on the EBN. This DFPA is also compared with the existing FPA and four other popular heuristics where the DFPA achieved better grading accuracy with an average accuracy of nearly 88%.

To study the flight dynamics of a generic hybrid fixed-wing UAV, the full six-degrees-of-freedom equations of motion of the aircraft are derived. Unlike conventional fixed-wing aircraft or multirotor drones, the flight dynamics of the hybrid aircraft are influenced by both sets of propulsion systems – the main petrol engine and the 4 fixed-rotors. Hence, a derivation of the flight dynamics is presented here as a result of the contribution from both propulsion systems. For this initial attempt, the main petrol engine is fixed at its location and has the sole purpose of providing horizontal thrust only. The position of the petrol engine is located along the X-body axis hence, no moment is created about the center of gravity (CG) by the main horizontal thrust. The 4 fixed rotors, on the other hand, provide vertical thrust along the Z-body axis with the associated roll and yaw. All 4-rotors are positioned on the same X-Y plane on the aircraft body axis. The paper concludes with the aircraft 6 degrees-of-freedom mathematical model of the Vertical Take-off and Landing (VTOL) Fixed-Wing (FW) Unmanned Aerial Vehicle (UAV).
