Extended Kalman filter (EKF) has been found as most widely used algorithm for state estimation due to its simplicity for implementation and theoretically attractive in the sense that minimizes the variance of the estimation error. Nevertheless it is known that EKF algorithm strictly assumed that the nature of the noise or errors in the system is Ga...

The current research focuses on the development of hovercraft via Arduino. The vehicle is designed with bag skirt structure in order to reduce friction for smooth operation. Nowadays, there are a lot of natural disaster occur in everywhere especially flood. However, hovercraft is a vehicle that need a driver to drive which can cause a danger to the...

Image segmentation is an image processing operation performed on the image in order to partition the image into some images based on the information contained in the original image. Image segmentation plays an important role in many medical imaging applications, image segmentation facilitates the anatomy process in a particular body of human body....

The direct current motor is an important drive configuration for many applications across a wide range of power and speeds. It has variable characteristics and is used extensively in variable-speed drives. The goals of this project are to control the direction and speed of a Direct Current (DC) motor. Due to the advancement of wireless technology,...

Nowadays, solar energy’s popularity is growing consistently every year, along with the growth of amazing solar technologies, which is considered to be one of the most popular. Non-renewable energy like petrol and gasoline is being replaced with solar energy, which is renewable energy. The main objective of this project is to design and simulate a r...

In general, spy robots were employed mostly in military field to patrol over the country border and also can be assigned for a rescue and search mission. Even though this technology has a rapid growth recently, the major problem is what is there in Malaysia security sector, there are many lacks in this technology if compared to other countries. Fur...

Weather forecast these days is unpredictable too be exact because of the climate changes drastically over weather. In cause of that, Weather Reporting System is mostly used to monitor the continuously changing climatic and weather conditions over controlled areas likes house, industry, agriculture and etc. in real time monitoring. Internet of Thing...

This project is about the design and development of solar and wind turbine system for power generation that supply to the domestic household in the remote area, which is unable to connect to the grid. The construction of renewable resources as the power generation of a small house in a remote area occurs to save the cost installation. Renewable ene...

A Graphical User Interface (GUI) design was developed to extract data from a data logger. The low-cost data logger was developed using a common pic18f4550 microcontroller. Simple data recording feature is implemented by using the Electrically Erasable Programmable Read-Only Memory (EEPROM) module from the microcontroller unit. The GUI software empl...

This paper studies particle filter algorithm to estimate the angular rate of a satellite without the rate sensor measurements. In this work, the performance of the algorithm is studied in terms of capability to estimate the angular rate by using the Euler angles attitude information only. The effects of the number of particles on the algorithm perf...

Image have a significant importance in many fields in human life such as, in medicine, photography, biology, astronomy, industry and defence. Thus, it attracts the attention of large number of researchers, among them those interested in preserving the image features from any factors that may reduce the image quality. One of these factors is the noi...

This paper presents the analyzed on Earth Centered Inertial (ECI) of Attitude Determination System (ADS) and satellite velocity data of RazakSAT by using analysis method. ADS are one sub-system in satellite as function to control the orientation of satellite relative with inertial references frame. ECI is one of inertial references frame of RazakSA...

In space, environmental torques exerts continuously on a satellite and may influence and affect the satellite’s attitude dynamics. The relative strength of the various torques will depend on both spacecraft environment and the structure of the spacecraft itself. RazakSAT is the world first remote sensing satellite launched into Near Equatorial Orbi...

The main aim of this paper is to propose a double layer neural network (DLNN) for solving a class of mixed-integer quadratic optimization problems. It is proven that the DLNN is globally stable in the sense of Lyapunov and the output of the proposed neural network converged globally to an optimal solution. Compared with conventional Boltzmann Machi...

Attitude Determination System (ADS) is a process to determine the attitude of a satellite by using on board sensors and attitude estimation algorithms to determine the orientation of the satellite which is relative to inertial reference frame such as Earth reference frame. The ADS is consists of an attitude sensor which provides the attitude and or...

Acoustics and vibration comfort levels are crucial criteria for the prospective customer to consider when purchasing a new vehicle. Therefore, in today’s competitive automobile markets, assessing the acoustics and vibration levels is substantial for automotive industries to produce vehicles that meet the expectations and demands of costumers. This...

This paper designs and investigates an observer system via Extended Kalman Filter algorithm to estimate the satellite’s Euler angles attitude during the absence of the attitude sensor measurement. This work contributes as a backup or an alternative system during unavailable attitude sensor measurement due to malfunction sensor or for cost reduction...

Timah Tasoh serves as a source of drinking water and industrial supplies, irrigation, tourism, as well as flood mitigation for the state of Perlis. However, the dam is also become one of the causes of flooding in the state and it gives a terrible consequences resulting in losses of various aspects. Therefore, to overcome this problem, an automated...

Attitude determination system (ADS) is a process to control the orientation of satellite to make sure that the orientation of satellite is relative to inertial reference frame such as Earth. Earth Centered Inertial (ECI) is one of reference frame for satellite that determines the attitude in three dimensional spacecraft. Since RazakSAT orbits on ea...
