Introduction: Stumbling or falling is a major health problem among the elderly which accounts for their majority of physical injuries such as pelvic fractures, disability, loss of independency and even death. The goal of the study was comparison of the effect of aerobic and resistance exercise on static and dynamic balance in old men. Methods: A quasi-experimental study was conducted and t...

OBJECTIVES To evaluate the long-term benefits of progressive resistance training in chronic stroke. DESIGN A 4-year follow-up of a randomized controlled trial of progressive resistance training. SUBJECTS Eighteen women and men (mean age 66 (standard deviation 4) from the original group of 24 post-stroke participants. METHODS The training group (n = 11) had participated in supervised progr...

PURPOSE To determine the effects of progressive resistance training on mobility, muscle strength, and quality of life in nursing-home residents with impaired mobility. METHODS Nursing-home residents aged 77 years and older with impaired mobility were recruited in Berlin, Germany. The eight-week exercise program consisted of progressive resistance training twice a week. Mobility (primary outco...

To continuously monitor health information using wireless sensors placed on a person is a promising application. Human body communication (HBC) is proposed as a low power, security and light-weight communication technology that could be applied in aforementioned applications. In this work, the characterization of HBC propagation delay and phase deviation were investigated for the first time. In...

Drag area (Ad ) is a primary factor determining aerodynamic resistance during level cycling and is therefore a key determinant of level time trial performance. However, Ad has traditionally been difficult to measure. Our purpose was to determine the value of adding field-measured Ad as a correlate of level cycling time trial performance. In the field, 19 male cyclists performed a level (22.1 km...

‎Let $G$ be a graph without an isolated vertex‎, ‎the normalized Laplacian matrix $tilde{mathcal{L}}(G)$‎ ‎is defined as $tilde{mathcal{L}}(G)=mathcal{D}^{-frac{1}{2}}mathcal{L}(G)mathcal{D}^{-frac{1}{2}}$‎, where ‎$mathcal{D}$ ‎is a‎ diagonal matrix whose entries are degree of ‎vertices ‎‎of ‎$‎G‎$‎‎. ‎The eigenvalues of‎ $tilde{mathcal{L}}(G)$ are ‎called as ‎the ‎normalized Laplacian eigenva...

In this paper, an approach is proposed for accurate locating of single phase faults in transmission lines using voltage signals measured at one-end. In this method, harmonic components of the voltage signals are extracted through Discrete Fourier Transform (DFT) and are normalized by a transformation. The proposed fault locator, which is designed based on Random Forests (RF) algorithm, is train...

Abstract In this article, we take a probabilistic look at Hölder's inequality, considering the ratio of terms in classical Hölder inequality for random vectors . We prove central limit theorem ratio, which then allows us to reverse up multiplicative constant with high probability. The models randomness include uniform distribution on balls and spheres. also provide Berry–Esseen–type result larg...

BACKGROUND In haematology/oncology units, the frequent and heavy use of broad-spectrum antimicrobials can lead to outbreaks of antimicrobial resistance. Increasing antimicrobial heterogeneity might be a useful strategy for preventing such resistance. METHODS A real-time antimicrobial use density (AUD) monitoring system (RAMS) was developed to precisely assess antimicrobial heterogeneity. This...
