background: there are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. in the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. methods: forty patients with valgus knee malalignment were randomly assigned to two equal numb...

Two novel devices, torsional actuator and torsional stepper motor, are described and their performance is investigated in detail. Both devices were designed to produce large angular displacement and large torque output from the piezoelectric d15 shear response. In the torsional actuator, the large displacement can be achieved due to built-in amplification of piezoelectric strain using the aspec...

The behavior of steel-concrete composite beams is strongly influenced by the type of shear connection between the steel beam and the concrete slab. For accurate analytical predictions, the structural model must account for the interlayer slip between these two components. In numerous engineering applications e.g., in the fields of structural optimization, structural reliability analysis, and fi...

Example Commercial Web servers typically maintain a ‘hit count’ component that records how many times each URL is accessed by clients over a period of time. To reduce latency, a Web server process does not maintain the hit counts in a file on disk but rather in a memoryresident table. Moreover, to increase throughput, Web server processes are often multi-threaded [HS98]. Therefore, public metho...

We present multiversion timestamp locking (MVTL), a new genre of multiversion concurrency control algorithms for serializable transactions. The key idea behind MVTL is simple and novel: lock individual time points instead of locking objects or versions. After showing what a generic MVTL algorithm looks like, we demonstrate MVTL’s expressiveness: we present several simple MVTL algorithms that ad...

Injection locking characteristics of oscillators are reviewed both theoretically and experimentally. Theoretical results coupled with experimental findings are presented. A simple method of deriving the equation for locking range is reported.

This paper proposes the use of Jacobi polynomials to approximate higher-order theories beam, plate, and shell structures. The Carrera unified formulation is used in this context express displacement kinematics a hierarchical form. In manner, classical complex can be implemented with ease. Particular attention focused on attenuation correction shear locking. Therefore, reduced integration as wel...

The goal of this study was to compare the biomechanical stability of cannulated locking screws and noncannulated cortical locking screws in a periarticular locking plate. Twelve fresh-frozen porcine tibias with a 1-cm gap created distal to the tibial plateau were used to simulate an unstable proximal tibial fracture. All specimens were fixed with a periarticular proximal lateral tibial locking ...

Anatomically precontoured locking plates are intended to facilitate the fixation of articular fractures and particularly those associated with osteoporosis. Fractures of the distal humerus are relatively uncommon injuries where operative intervention can be exceptionally challenging. The distal humeral trochlea provides a very narrow anatomical window through which to pass a fixed-angle locking...
