Rehabilitation is an important process to restore muscle strength and joint's range of motion. This paper proposes a biomechatronic design of a robotic arm that is able to mimic the natural movement of the human shoulder, elbow and wrist joint. In a preliminary experiment, a subject was asked to perform four different arm movements using the developed robotic arm for a period of two weeks. The experimental...
This paper presents a method for speech emotion recognition using spectrograms and deep convolutional neural network (CNN). Spectrograms generated from the speech signals are input to the deep CNN. The proposed model consisting of three convolutional layers and three fully connected layers extract discriminative features from spectrogram images and outputs predictions for the seven emotions. In this...
This paper explores the role of haptics in wireless communication and bilateral system to improve the development on bilateral teleoperation system in the future. The telecommunication applications in haptic is to separate between master and slave control in various distances. This purpose is commonly used in medical surgery between different countries or buildings. This technology helps to analyse...
This paper presents a routing protocol called Load Distributed Mesh Routing (LDMR) that is developed for Wireless Mesh Network (WMN) with IEEE 802.11 standard. The LDMR protocol decides on the potential next hop nodes based on a quadrant and distance information. Then, the Next Hop Forwarding (NHF) decision is used to select the best next hop nodes based on Packet Success Rate (PSR) and maximum velocity...
Fractal Image Compression (FIC) is one of the most popular techniques used in image and video compression due to its simplicity and superior performance. The main drawback of FIC arises from its time consuming operation, especially when a full search is attempted. Hence, it is very challenging to achieve a real-time operation if this algorithm is implemented in general processor unit. In this paper,...
Socially Assistive Robotics (SAR) is an emerging field of research focused on assisting people through social interaction. Nowadays, attention has been paid on socially assistive robots that mediate communication and social exchange, especially for people with disabilities. Cerebral palsy (CP) is a common neurological disorder among children that impairs motor function and may involve cognitive dysfunction...
Rapid technology evolvement in the area of wireless sensor networks (WSNs) has led to many application-specific protocols that are particularly developed to cover different fields of usage and various network scenarios. Energy efficiency is one of the apparent challenges facing WSNs which has impacted immensely on the network performance. Hence, clustering protocols that eliminate energy inefficiencies...
This thesis presents a biomechatronics approach to the design and fabrication of an artificial robotic arm called Artificial Hand Gripper (AHG), consisting of a shoulder, arm, elbow, forearm, wrist and hand. Detail 3D designs of the AHG are described including an elbow powered by a car's power window motor, DC motor powered wrist and a string actuated AHG with 5 artificial fingers which acts as slave...
Selection of energy source depends on several factors, including energy availability, economic and power requirements. Hydro power is more cost effective than any other form of renewable power. This paper studies the performance of various stator designs in a micro hydro generator. The generator generates energy using rainwater that falls from the roof drainage system. The rainwater flows through...
Cerebral palsy (CP) is a lifelong physical disorder of movement and posture, at times associated with other medical and cognitive impairment including joint attention. Nowadays, advancement of robotic technology promises potential application to CP rehabilitation. Previous study resulted that robotic technology has successfully elicited interest and joint attention in young children. This study proposes...
Arm rehabilitation activities require continuous monitoring process in order to provide information on rehabilitation results to be analyzed by therapist. The purpose of monitoring is to help them to improve and customize the rehabilitation process. Moreover, a portable and simple home-based rehabilitation device can help patients to improve daily rehabilitation activity. Some previous studies regarding...
An Automated Storage and Retrieval System (ASRS) is an integrated automated system consists of hardware, software and networking system which communicates with each other over a fieldbus network. It allows a range of control strategies to be investigated using the design and algorithm developed. This storage system commonly operates under computerized control known as Computer Supervisory Control...
This paper describes the identification of engagement measures during Human Robot Interaction (HRI) between a humanoid robot and children with Cerebral Palsy (CP) and its' experimental framework. This paper begins with an introduction to CP, HRI and Socially Assistive Robotic (SAR). The importance of engagement in HRI and suggested attention measurement of HRI will be discussed. The paper presents...
Fake identities and user accounts (also called "Sybils") in online communities represent today a treasure for adversaries to spread fake product reviews, malware and spam on social networks, and Astroturf political campaigns. State-of-the-art in the defense mechanisms includes Automated Turing Tests (ATTs such as CAPTCHAs) and graph-based Sybil detectors. Sybil detectors in social networks...
A wireless sensor network is made up of battery operated devices that have sensing, processing and transmitting capabilities. The design constraint of a wireless sensor network is its network lifetime. In order to prolong the network lifetime, the sensor nodes must be able to use the minimal energy to transmit data to the base station. Hence, an efficient protocol is needed. One method to reduce the...
Distributional lexical semantics is an empirical approach that is mainly concerned with modeling words' meanings using word distribution statistics gathered from very large corpora. It is basically built on the Distributional Hypothesis by Zellig Harris in 1970, which states that the difference in words' meanings is associated with the difference in their distribution in text. This difference in meaning...
This work is based on obtaining surface EMG signals from lower back muscles using a data logger by Pico Log technology. The electrodes used are Ag/AgCl and applied after a clean surface washing by alcohol of erector spine muscle for a subject under two posture conditions. The conditioning circuit used in this paper is selectively choosing the 20-500Hz dominant frequency range and 0.4 to 2.4 Volts...
In this paper we present a review on the frequency content and voltage level in biomedical signals beside showing how extraction of chosen features and parameters from these signals, are important for many medical diagnostic applications. A 4th order band-pass filter using high and low-pass Sallen Key active filters are proposed, and the values of passive component for different biomedical filters...
