We study p-adic multiresolution analyses (MRAs). A complete characterisation of test functions generating MRAs (scaling functions) is given. We prove that only 1-periodic test functions may be taken as orthogonal scaling functions. We also suggest a method for the construction of wavelet functions and prove that any wavelet function generates a p-adic wavelet frame.
Introduction: Foot pronation can lead to different lower limb injuries. The purpose of this study was to investigate the effect of long-term training on sand on ankle joint co-contraction in individuals with pronated feet during walking. Methods: The present study was a randomised controlled clinical trial type. Statistical samples of the present study included 15 males with excessive pronated...
Background & Aims: Acute acromioclavicular (AC) joint dislocation is common in shoulder injuries. Considering the biomechanics of this joint, the use of a treatment method, which can restore joint physiology and biomechanics to the extent possible, is important. This study aimed to compare the treatment of acute AC joint dislocation by screw fixation with and without ligament reconstruction. Me...
At the initial phase of the mechanical product development, it is very important to effectively obtain the modal damping ratio of the bolted joint structure for accurately predicting dynamic response. The energy dissipation has been estimated using a finite element model incorporating the effect of pretension force of the bolted joint. First, the modal damping ratios of the first four modes are...
This paper is concerned with the minimization of roundoff noise subject to 2-norm dynamic-range scaling constraints in two-dimensional (2-D) state-space digital filters. Two methods are proposed, with the first one using error feedback alone and the second one using joint error feedback and coordinate transformation optimization. In the first method, several techniques for the determination of ...
Anterior cruciate ligament(ACL) and meniscus injuries are the most common injuries in athletes. History, physical exam, MIR, arthrography and arthroscopy are used to confirm the diagnosis. In the present observational descriptive analytical study, the diagnostic value of clinical test was compared with arthroscopic findings. 68 athletes suspected of meniscus or ACL injuries, were sele...
abstract background: corrosion and scaling are of the most important characteristics of drinking water, affecting public health and water industry economy. the aim of the present study was to evaluate the corrosion and scaling potential of potable water supplied by saqqez rural water and wastewater company. materials and methods: this was a descriptive study conducted on 142 samples taken from ...
Background & purpose: One of the major factors in the quality of drinking water is corrosion and scaling. The aim of the present study was to evaluate corrosion and scaling potential of drinking water supply network in Juybar (A city in Iran). Materials and Methods: 60 samples of drinking water in distribution network were collected randomly in summer and autumn seasons and transferred into ...
Introduction: Corrosion and scaling are important factors affecting drinking water quality, causing health and economic problems. This study aimed to investigate the indicators of corrosion and scaling in Rafsanjan drinking water. Materials and Methods: The present descriptive cross-sectional study was conducted in winter 2018 and spring 2019 in Rafsanjan. The 56 samples were randomly taken fr...
Background and Aim: This study aimed to assess the effects of zinc supplementation on the clinical signs of patients with plaque-type psoriasis with skin congestion under 20%. Materials and Methods: This randomized double-blinded clinical trial included 44 patients with plaque-type psoriasis with skin congestion under 20% referring to the Imam Reza Hospital in Ardabil, Iran. The patients with ...
