Reversible computation plays an important role in low power circuit design and efficient energy recycling. In this paper, a switch controlled efficient Reversible Full Adder/Subtractor (RFAS) is presented. RFAS block is further used in the construction of n-bit adder/subtractor. The proposed design is analyzed and compared against the existing reversible techniques. Features such as, hardware cost,...
Magnetic Resonance Image is one of the technologies used for diagnosing brain cancer. Radiographers use the information obtained from MRI images to diagnose the disease and plan further treatment for the patient. MRI images are always corrupted with noise. Removing noise from images is crucial but it is not an easy task. Filtering algorithm is the most common method used to remove noise. A segmentation...
One of the current research problems in the field of visual surveillance is optimizing the locations of the visual sensors. The efficiency of visual sensor localization becomes increasingly demanding as it can directly impact the efficiency of allocated resources as well as system performance. This problem can be divided to two sub-problems namely how to prioritize the area of interest and how to...
Rapid changes of technology in recent years, especially in biomedical engineering field have a big impact to the society. One of the forefront technologies that gaining a footprint among the researchers is retinal based-screening system. Researchers in both engineering and medical fields have studied extensively the property of retina as it provides visible points that exhibit various symptoms of...
Digital logic design is an essential topic in the computer science curriculum. A major challenge in teaching the logic design is to have the students connect their theoretical knowledge with the practical experience. Many useful computer programs are available that can help overcome this issue while covering various aspects of the logic design. The programs range from simple simulators to advanced...
Video surveillance system is an important system to monitor safety and security for public place. Unfortunately, most of them do not have additional. In this paper, we have proposed an algorithm for detect human aggressive behavior by using Microsoft Kinect sensor. In our proposed algorithm, Cartesian coordinate formula is used for calculate position of body joints detected by Microsoft Kinect sensor...
In recent years intelligent soft computing technique such as fuzzy inference system (FIS) is proven to be an efficient and suitable when applied to variety of systems. In this paper, we intend to formulate two fuzzy inference systems; sensors based navigation technique for an autonomous vehicle in cluttered dynamic environment. The first FIS controller utilises three sensors based information such...
In many applications such as dealing with database, continuous environment and humanoid robots, the machine often deals with large amount of data every day of work. Dealing with large amount of data requires fast as well as accurate learning algorithms to do the classification. A new supervised non parametric Partial Histogram Bayes learning algorithm (PHBayes) is proposed and presented in this paper...
Modeling the camera coverage is evidently indispensable to meet the requirements of a variety of visual sensor related applications. It is critical to be able to compute the camera coverage and to plan the related application accordingly. However, it is well known that camera coverage can be modeled geometrically. In contrast, tackling the camera visibility in arbitrary scenario is usually the challenging...
Studies of medical image segmentation have long been done as a mean to distinguish object region from one to another for further image analysis. The segmentation of lung region in chest X-ray (CXR) based on object edge detection is one of the popular method applied. Early edge detection algorithms like Sobel, Prewitt and Laplacian have been used to segment the lung however, none of them can successfully...
Efficient data dissemination is a key of successful Vehicular Ad Hoc Networks (VANETs) applications. In VANETs, one of the main challenges is how to overcome the intermittent vehicle-to-vehicle connectivity problem. Secondly, how to increase the connecting possibility in the sparse environment (during off peak hour, highway etc.). Placing Road Side Units (RSUs) along roadside acting as a buffer point,...
Agriculture is one of the main sources that contribute to the economic development in the country. However, diseases that attack the crops have given a little impact to the agricultural production. Generally, plant pathologist has the difficulties to detect the symptoms that relate to the plant disease. The plant usually gets infected that are caused by different plant pathogens such as bacteria,...
In this paper, an affordable low specification 16-bit photon counting system has been prototyped. This is to overcome the high cost equipments which are design for broad applications., This system is developed specifically for the measurement of spectral delayed luminescence of saliva and is able to communicate with PC through USB port. Schematics of the systems are described in detail followed by...
This paper presents the tuning of PID control parameters for position feedback control of motor and the position reference design for grasping task by a 7-degree of freedom (DOF) three-fingered robotic hand. The system of the robotic hand consists of DC-motors, magnetic encoder and a motion controller unit. The robotic hand has three fingers where each finger has two joints and two links made of perspective...
The purpose of this project is to design and construct a seven degree of freedom (DOF) three-fingered robotic hand. This project is the continuity from a previous work which has successfully constructed two-DOF robotic finger. In this work, a palm that holds all the three fingers is designed and the design of the current finger is improved. All components are fabricated and assembled to produce a...
