background: excessive lumbar vertebrae translation and rotation in sagittal plane has been attributed as an associated factor of lumbar segmental instability (lsi) and low back pain (lbp). reduction of these abnormalities improves back pain. the aim of this study was to investigate the effect of core stability exercise on the translation and rotation of lumbar vertebrae in sagittal plane in pat...

This paper investigates, how two fundamental measurement operations in Euclidean space, namely the construction of a straight line of given orientation angle and the measurement of distances along this line, are mapped to the non-Euclidean log-polar image plane. It is shown, how these two operations can be efficiently implemented for discrete log-polar images. The measurement operations are use...

In recent years, the Internet has proven its ability to carry real-time data, including voice. Today, a small amount of voice traffic has already been diverted from the Public Switched Telephone Network (PSTN) to the Internet. If it expands, this phenomenon can completely change the rules of the game for telecommunications. This paper presents an overview of the main technical problems to be ad...

A fast rotation of the camera during the image acquisition results in a blurred image, which typically shows curved smears. We propose a novel algorithm for estimating both the camera rotation axis and the camera angular speed from a single blurred image. The algorithm is based on local analysis of the blur smears. Contrary to the existing methods, we treat the more general case where the rotat...

> Motivation = Visible difference between renderings from refined geometry and coarser geometry is not constant over the image plane (see figure below) = The computational effort for refining should be aimed to the features, which cause highest difference > Problem = Evaluation of visible differences is too expensive to be done in realtime > Our strategy = Perceptual analysis is done as a prepr...

This paper proposes a “privacy conscious” video communication system utilizing core technology of the JPEG2000 international standard for digital image data compression. The system works not only as a conventional video communication tool but also serves as an “awareness communication” tool. In addition, bit rate for transmitting video data and hardware complexity of the system are also reduced...

Modern network interfaces demand highly intelligent traffic management in addition to the basic requirement of wire speed packet forwarding. Several vendors are releasing network processors in order to handle these demands. Network workloads can be classified into data plane and control plane workloads, however most network processors are optimized for data plane. Also, existing benchmark suite...

Control Plane Design and Performance Analysis for Optical Multicast-Capable Datacenter Networks

The forces experienced while surgically cutting anatomical tissues from a sheep and two rats were investigated for three scissor types. Data were collected in situ using instrumented Mayo, Metzenbaum, and Iris scissors immediately after death to minimize post-mortem effects. The force-position relationship, the frequency components present in the signal, the significance of the cutting rate, as...

Credit scoring is a kind of binary classification problem that contains important information for manager to make a decision in particularly in banking authorities. Obtained scores provide a practical credit decision for a loan officer to classify clients to reject or accept for payment loan. For this sake, in this paper a data envelopment analysis- discriminant analysis (DEA-DA) approach is us...
