Exergames have been proposed as a potential tool to improve the current practice of musculoskeletal rehabilitation. Inertial or optical motion capture sensors are commonly used to track the subject's movements. However, the use of these motion capture tools suffers from the lack of accuracy in estimating joint angles, which could lead to wrong data interpretation. In this study, we proposed a r...

The paper presents the design and validation of a three-segment human body model. The model is aimed at the reconstruction of motion trajectories of the shank, thigh and HAT (Head-Arms-Trunk) segments in sit-to-stand-motion using low cost inertial sensors. For this purpose the Extended Kalman filter is applied for fusion of model data and data acquired through measurements. The simplifications,...

Bilateral filtering is a simple, non-iterative scheme for texture removal and edge-preserving and noise-reducing smoothing filter. The intensity value at each pixel in an image is replaced by a weighted average of intensity values from nearby pixels. This weight is based on a Gaussian distribution. Thus noise is averaged and signal strength is preserved. Performance parameters of bilateral filt...

Downlo ulating tumor cells (CTC) quantified in cancer patients' blood can predict disease outcome and se to therapy. However, the CTC analysis platforms commonly used cannot capture live CTCs and only to tumors of epithelial origin. To address these limitations, we have developed a novel cancer detection m which measures telomerase activity from live CTCs captured on a parylene-C slot microfilt...

Recent years we have witnessed a great increase in modeling data as large graphs in multiple domains, such as XML, the semantic web, social network. In these circumstances, researchers are interested in querying the large graph like that: Given a large graph G, and a query Q, we report all the matches of Q in G. Since subgraph isomorphism checking is proved to be NP-Complete[1], it is infeasibl...

At this article will be created a software written in visual basic for efficiency and penetration calculation in a fibrous filter medium for given values of particles diameter that are retained in the filter. Initially, will become report of mathematical models of air filtration in fibrous filters media and then will develop the code and the graphical interface of application, that are the base...

Circulating tumor cells (CTC) quantified in cancer patients' blood can predict disease outcome and response to therapy. However, the CTC analysis platforms commonly used cannot capture live CTCs and only apply to tumors of epithelial origin. To address these limitations, we have developed a novel cancer detection platform which measures telomerase activity from live CTCs captured on a parylene-...

Pose estimation is a critical skill in mobile robotics and is often accomplished using onboard sensors and a Kalman filter estimation technique. For systems to run online, computational efficiency of the filter design is crucial, especially when faced with limited computing resources. In this paper, we present a novel approach to serially process high-dimensional measurements in the Sigma-Point...

Accurate network bandwidth measurement is important to a variety of network applications. Unfortunately, accurate bandwidth measurement is difficult. We describe some current bandwidth measurement techniques: using throughput, pathchar[8], and Packet Pair [2]. We explain some of the problems with these techniques, including poor accuracy, poor scalability, lack of statistical robustness, poor a...

Motion retiming is an important tool used to edit character animations. It consists of changing the time at which an action occurs during an animation. One example might be editing an animation of a person playing football to change the precise time at which the ball is kicked. It is, nevertheless, a non-trivial task to retime the motion of a set of joints, since spatio-temporal correlation exi...
