Abstract Research on breast cancer has been widely conducted and previously studied with various methods or algorithms to categorize it into benign malignant groups. In ANN algorithm, one method called back propagation network is utilized solve complex problems related identification, pattern recognition prediction, so forth. The objective of the present study investigate level accuracy perform...

Background: Job back pain is of the most common occupational injuries in the world that affects people's physical and mental health. The purpose of this study was to assess back compressive force (BCF) in manual handling tasks among workers of a chemical manufacturing company using the UTAH method. Materials and Methods: This descriptive study was carried out on a group of 35 workers doing man...

introduction: ovako working posture analyzing system (owas) is a method for evaluating postural load during work. the owas method is based on a simple and systematic classification of work postures combined with observations of work tasks. the aim of this study was the assessment of various postures during the work in iron and steel industry, navard ahwas, using owas method. materials and metho...

AIM The Back School is a widely accepted and effective method for treating low back pain, whereas no scientific evidence exists about the effects of the Pilates CovaTech method. With this study we wanted to evaluate the efficacy of this new method in patients with low back pain. METHODS Fifty-three patients with at least 3 months of nonspecific low back pain were entered into a Pilates therap...

The four existing stable factorization methods for symmetric indefinite pivoting (row or column exchanges) maintains a band structure in the reduced matrix and the factors, but destroys symmetry completely once an off-diagonal pivot is used. Two-by-two block pivoting maintains symmetry at all times, but quickly destroys the band structure. Gaussian reduction to tridiagonal also maintains symmet...

Ultrasonic, used in security technology such as car collision avoidance and distance measurement, also can be used in detecting obstruction behind the car when backing up. In this paper, we analyze the interference of ultrasonic signal when transmitting and receiving, and then resolve it by software. There is a blind area and distance limitation in ultrasonic distance measurement .The cause of ...

Currently, the back-propagation is the most widely applied neural network algorithm at present. However, its slow learning speed and local minima problem are often cited as the major weakness of the algorithm. In this paper, described are an adaptive training algorithm based on selective retraining of patterns through error analysis, and dynamic adaptation of learning rate and momentum through ...
