Objectives. To determine the minimum lateral bone coverage required for securing stable fixation of the porous-coated acetabular components (cups) in hip dysplasia. Methods. In total, 215 primary total hip arthroplasties in 199 patients were reviewed. The average follow-up period was 49 months (range: 24-77 months). The lateral bone coverage of the cups was assessed by determining the cup cente...

Amplitude modulation (AM) and frequency modulation (FM) are commonly used in communication, but their relative contributions to speech recognition have not been fully explored. To bridge this gap, we derived slowly varying AM and FM from speech sounds and conducted listening tests using stimuli with different modulations in normal-hearing and cochlear-implant subjects. We found that although AM...

The cooling field dependence of the exchange bias field in ferromagnet/antiferromagnet (FM/AF) multilayers demonstrates that the bulk AF spin structure plays a crucial role on the origin of exchange bias. FM/AF/FM trilayers were designed to eliminate any interlayer exchange coupling between the FM slabs. By choosing the magnetic cooling field, the AF is ordered below its Néel temperature with t...

poly (propylene fumarate) (ppf), a linear unsaturated polyester consisting of alternating propylene glycol and fumaric acid units, can be cured in vivo to fill the skeletal defects with minimal surgical intervention. many different methods have been reported for synthesizing ppf, but none of them gives a clear method. the present paper introduces two new methods in ppf synthesis: modified reflu...

Building information modelling (BIM) has demonstrated its potential as a solution providing support to series of operations related facility management (FM) through building data retrieval, analysis, and processing. However, some challenges the effective adoption BIM-centred FM systems occur in their design implementation, causing obstacles usability. Among these are customization structure for...

In order to study the shrinkage process of clayey soil, we perform a modified laboratory test allowing to measure simultaneously and continuously the vertical displacement and the weight of natural state specimen. The experiment was conducted on undisturbed clayey specimen. Using the experimental results, and on the basis of the existing relation between the soil water content and its structura...

This study presents a novel technique to reconstruct the missing frequency bands of band-limited telephone speech signals. This technique is based on the Amplitude and Frequency Modulation (AM-FM) model, which models the speech signal as the sum of N successive AM-FM signals. Based on a least-mean-square error criterion, each AM-FM signal is modified using an iterative algorithm in order to reg...
