Background High tibial osteotomy (HTO) is a valuable treatment option in the high-demand patient with chondral damage and an altered mechanical axis. Traditional opening wedge HTO performed with metal plates has several limitations, including hardware irritation, obscuration of detail on magnetic resonance imaging, and complexity of revision surgery. Recently, an all-polyetheretherketone (PEEK)...

Multiple instruction rollback (MIR) is a technique that has been implemented in mainframe computers to provide rapid recovery from transient processor failures. Hardware-based MIR designs eliminate rollback data hazards by providing data redundancy implemented in hardware. Compilerbased MIR designshave also been developed which remove rollbackdata hazards directlywith data-flowtransformations. ...

Redundant faults in digital circuits not only result in extra hardware but also mask other faults and may also make undetectable fault detectable. Redundancies increase the chip area, the power consumption, and often propagation delays in the circuit and might even reduce the yield [5]. This paper is a result of literary search for detection and removal of such faults. This paper addresses proc...

This paper presents a mechanism that organizes processes in the hierarchy and efficiently maintains it in the presence of addition/removal of nodes to the system, and in the presence of node failures. This mechanism can support total order of broadcasts and does not rely on any specific system features or special hardware. In addition, it can concurrently support multiple logical structures, su...

Complex three dimensional graphics rendering is computationally very intensive process, so even the newest microprocessors cannot handle more complicated scenes in real time. Therefore to produce realistic rendering, hardware solutions are required. This paper discusses an FPGA implementation which complies with the newer, programmable standards. As the design implements a somewhat unique hidde...

Filtering noise, in real time, has applications in speech and image processing. Considerable interest has arisen in recent years regarding filtering in the wavelet transform domain. This technique has been effective in noise removal with minimum side effects on important features such as image details and edges. In this paper, the effectiveness of both soft and hard thresholding for desired det...

In this paper, we present a low-cost vision based system for handling of hazardous waste in an unstructured environment. The prototype system described shows the feasibility of sorting and removal of randomly mixed and oriented flexible objects from a bin using inexpensive and widely available hardware. Our experiments show that the utilization of even the simplest constructs is sufficient for ...

Computed tomography angiography (CTA) data sets without hardware based bone subtraction have the disadvantage of containing the bone structures which particularly overlap with vessel intensities; therefore vessel segmentation is hampered. Segmentation methods developed for CTA without bones can not handle these data sets and manual cerebral vessel segmentation is not realizable in clinical rout...

A rare case of unilateral bicondylar fractures of the femoral condyles is presented. Internal fixation of the fragments was achieved by three cancellous lag screws, followed by a short period of cast immobilization and intensive physiotherapy. Full weight bearing was allowed 3 months postoperatively. Full range of motion of the knee and no presence of articular defects on femoral condyles were ...

We describe the technical aspects of an arthroscopy-assisted procedure indicated for the management of acute unstable acromioclavicular joint injuries, consisting of a synthetic augmentation of both the coracoclavicular and acromioclavicular ligaments, that anatomically reproduces the coracoclavicular biomechanics and offers fixation that keeps the torn ends of the ligaments facing one another,...
