Anadara granosa (Ag) is a marine bivalve cockles which can be found in the tidal mudflats bordering the coastal region of many south East Asian countries particularly Malaysia, Indonesia and Thailand. This research is aim to investigate the potential of Malaysian cockle (Anadara Granosa) shell to be used as bone substitute material. Therefore, in this study two types of bioceramic has been produced...
This paper looks back the study history of eye movement measure system. Secondly, through analysis of basic formats and characters of eye movement and research on the rule of binocular movement, the advantages and disadvantages of the eye movement is contrasted, and then it has mainly discussed about the infrared TV eye movement system. At last, an application analysis of eye movement measure system...
Major progress in robotics turns today's humanoid robots into ever safer, more robust, and more agile agents by the moment. However, it is still a long way until robots can safely operate in open environments. Especially in the area of service robotics, the need arises for robots to work flexibly in a human centered environment. One way towards this goal is to incorporate more and more of the mechanisms...
A five-fingered, multi-sensory biomechatronic hand with sEMG interface is presented. The cambered palm is specially designed to enhance the stability while grasping. The location of the thumb is designed by maximizing interaction area between the thumb and other fingers. The opposite thumb could grasp along a cone surface, while maintaining its function. By taken the advantage of coupling linkage...
In this overview paper we present current work on safety analysis for physical Human-Robot Interaction (pHRI) and motion control methods for robotic co-workers. In particular, we introduce the analysis tools for investigating the potential injury a human would suffer during robot-human impacts. Furthermore, we outline our concept for establishing a procedure towards standardized crash testing in robotics...
Measurement of Internal eye pressure (IOP) is a good starting point for examining whether your eyes are suffered by glaucoma or not. An issue of IOP measurement is that we are obliged to evaluate it under that the equivalent pressure coming from cornea stiffness is unknown. Therefore, the IOP measurement depends upon the structural stiffness of cornea. The goal of this work is to examine how the structural...
Understanding the spatial dimensionality and temporal context of human hand actions can provide representations for programming grasping actions in robots and inspire design of new robotic and prosthetic hands. The natural representation of human hand motion has high dimensionality. For specific activities such as handling and grasping of objects, the commonly observed hand motions lie on a lower-dimensional...
Walking gait based on actual machine elements that capture the major features of human locomotion may enhance the understanding of human leg morphology and control, and provide necessary background science for the design and control of human-robot exoskeleton interaction system. This paper describes an investigation into the biomechanical effects of human lower limb joints during different loaded...
We have developed a visual-tracking-system (VTS) which uses stereo-imaging to track the motion of markers on patients during cardiac SPECT imaging with the goal of using the tracked motion to correct for patient motion. The aim of this study is to determine using MRI in volunteers if the rigid-body-motion (RBM) model can be used to predict the motion of the heart within the chest from the motion of...
To systematically couple images and physiological models according to their respective merits, state-space filtering frameworks have been proposed for cardiac deformation recovery with promising results. Nevertheless, as thousands of forward simulations are required in every filtering step, the computational complexity is too high to be practical. To reduce the computational complexity without a significant...
In this work, we present a computational model of a quietly standing human. The model is composed of a system of three rigid links with two joints, one at the ankle and one at the hip. This is consistent with considerable experimental data which indicates that humans keep their knee angle nearly constant when dealing with small perturbations to their posture. An optimal control problem is designed...
Advanced bioreactors are essential for meeting the complex requirements of in vitro ligament tissue engineering. A novel bioreactor system for the functional tissue engineering of ligaments, combined with culture medium perfusion over long periods of time and capability to apply cyclic mechanical loadings to three-dimensional scaffolds independently housed in six chambers, was developed. Well-controlled...
The paper presents a new numerical package for modelling and simulation of human circulatory system. The package provides many functions that are required in cardiovascular biomechanics. It is very useful tool for studying behavior of individual components of the human circulatory system, such as: left/right ventricular, systemic venous/arterial circulation, pulmonary arterial/venous circulation etc...
Vision and speech are the two natural ways of human communication. The major challenge is to create reliable perceptual technologies that allow applications of communication with multiple modalities. There are many options for restoring this function and, human machine interface is one of its kinds, which is the focus of the present work. This paper presents the design and development of a human-computer...
A new method is reported for human muscle force modeling based on the fuzzy theory. First, a Hill-based muscle force model was built. The muscle activation parameters were ascertained by fuzzy inferential algorithm as the input of the Hill-based muscle force. Then, a weightlifting motor task was implemented. Four channels of electromyography signals and twelve virtual markers motion data were collected...
Physics-based approach for character animation has advantages in interactive AR applications in that the approach can create realistic character motions that are responsive to non-predefined environment and user inputs. In this paper, we introduce two subjects on physics-based character animation. Biomechanical modeling of human characters is an effort to create more human-like motions than conventional...
Many studies of human postural control use data from video-captured discrete marker locations to analyze via complex inverse kinematic reconstruction the postural responses to a perturbation. We propose here that Principal Component Analysis of this marker data provides a simpler way to get an overview of postural perturbation responses. Using short (1, 4, and 16 mm) anterior platform step translations...
Recently, the studies of human motion analysis have attracted great attention among the researches in the field of biomechanics, medicine and sports by analyzing the joints, postures, and movements of the human. Our research focuses on analyzing the joints movement of a professional golfer. We represent those joint movements with an articulate stick human model. This paper presents a method for tracking...
Multi-channel ECoG signals are directly recorded from the surface of brain during finger flexion. Here they are used to construct brain functional networks based on phase synchronization theory. The channels of ECoG signals are considered as the nodes of brain functional networks, and the interactions among the channels suggest the connectivity of brain functional networks. The edge between two different...
Usually the recognition of daily human activity need to collect multi-sensor data, this paper applies an information fusion algorithm based Naive Bayes so as to obtain higher-level contexts from a small number of sensor. The sensor data from accelerometer node are firstly classified by C4.5 Decision Tree algorithm, once the confusion matrix of each sensor node have be gotten, the sensor fusion can...
