INTRODUCTION Fractures of the neck of the femoral component have been reported in uncemented total hip replacements, however, to our knowledge, no fractures of the neck of a cementless forged titanium alloy femoral stem coated in the proximal third with hydroxy-apatite have been reported in the medical literature. CASE PRESENTATION This case report describes a fracture of the neck of a cement...

In this paper, we introduce and compare two off-line, text independent writer verification systems. At the core of the first system are Hidden Markov Model (HMM) based recognizers. The second system uses Gaussian Mixture Models (GMMs) to model a person’s handwriting. Both systems are evaluated on two test sets consisting of unskillfully forged and skillfully forged text lines, respectively. In ...

Abstract Computational fluid dynamics (CFD) is applied to investigate rotational sloshing waves in a top-submerged-lance (TSL) cylindrical metal bath. The study an extension of recent work the authors, where top injection Ar into metallic bath was examined quasi-2D flat setup, allowing numerical model be extensively validated against experimental data based on x-ray radiography. new analysis ga...

Refactorings are behavior-preserving program transformations that automate design level changes in object-oriented applications. Our previous research established that many schema transformations, design patterns, and hot-spot meta-patterns are automatable. This research evaluates whether refactoring technology can be transferred to the mainstream by restructuring non-trivial C++ applications. ...

The paper reviews six examples of CFD applications, useful for: minerals, power generation and oil & gas industry. The review starts with the multiphase modeling of gas injection into a liquid bath, where the CFD results were validated against experimental data. The example is very useful for metal extraction/refining industry. Simulation of a mineral concentrator bin is presented next, where m...

A headed reinforcing bar is a new type of reinforcement with a T-shaped anchor connected to the end of a reinforcing bar. Conceptually, the bar is usually a tension member or compression one depending on structural engineering applications. The T-shaped anchor, referred to as head in the rest of this report is a relatively stiff steel "plate" in terms of its structural behavior. When embedded i...

Through an innovative new policy forged with a single insurer, Honeywell is consolidating risks as diverse as fire protection and currency fluctuations--and saving a bundle.
