Comparison of six different parameter estimation methods in wind power applications
In this paper, the different parameter estimation methods such as maximum likelihood method, least square method, weighted least square method, moments method, the method based on quantiles and maximum spacing method for the Weibull distribution which are widely accepted in wind power studies are presented and discussed. The effect of the selecting parameter estimation method on the estimation of wind power is also...

Modified damage location indices in beam-like structure: Analytical study
Proposed modifications to two existing algorithms, based on mode shape, for locating of damage in a beam like structure model are presented in this paper. The Curvature Damage Factor (CDF) developed by Wahab and Roeck (1999) computes the change in mode shape curvature between two sets of mode vectors, that is, undamaged and damaged conditions. The local stiffness indicator (LSI) was developed by Ismail and Abdul Razak...

Effect of hormonal and antibiotic treatment of Holstein cows with uterine discharges at 25 days in milk on reproductive performance in Mexican Plateau
Endometritis treatment is a controversial topic among veterinary practitioners. The objective of this study was to evaluate reproductive profiles of dairy cows that presented uterine discharge at 25 days in milk and were treated with hormones and a specific antibiotic for intrauterine infusion. In a single herd, at 25 (±5) days after parturition, the reproductive tract (vulva, vagina, cervix and size of the...

Prediction of permeability from reservoir main properties using neural network
Prediction on permeability is an essential task in reservoir engineering as it has great influences on oil and gas production, while porous media grain size, sorting, cementing, porosity, specific surface area, direction and location of grain and irreduction water saturation have effects on permeability. In this project we studied the effect of porosity, specific surface area and irreduction water saturation as main...

The use of geographic information system (GIS) in crisis management for Istanbul city
Nowadays, integrated disaster management includes the phases [(response and recovery (crisis management, after the disaster), and mitigation and preparedness (risk management, before disaster)]. Legal framework of disaster management phases in Turkey includes only crisis management. Principles of planning to crisis management must be for fast first and emergency aid to victims and to oriented fast and correctly to the...

A survey study of military medical students to autopsy in modern medical education
Military medical students will serve emergency in wars or natural disasters, so the autopsy teaching is an important value for their future career. To observe the military medical students’ attitudes to autopsy in the modern medical education, a survey study was undertaken to observe the military medical students’ attitudes to autopsy in a teaching hospital affiliated to military medical university....

Glycolic acid peeling in the treatment of mild to moderate inflammatory facial acne vulgaris
Chemical peeling of the skin involves the topical application of a chemical agent in order to produce a controlled injury to a desired depth, thus allowing subsequent regeneration of the skin which can result in improved texture, more homogeneous pigmentation and less wrinkling. Acne vulgaris is one of the most common skin diseases. The aim of the actual study was to examine and compare the efficiency, skin tolerance...

Mathematical modeling for analysis cable structures
The cable structures are long tension structures. The main aim of this paper is to provide a new efficient method in all aspects of analysis of tension structures. Tension structures belong to high- nonlinearity structures. The approach of the proposed method is based on the principle of conservation of energy. In this paper a theory for nonlinear dynamics response analysis of tension structure is based on the...

Effects of restricted nutrition on biochemical parameters of liver function in pregnant Ghezel ewes
This study was conducted in order to determine the effects of low energy diets (that is food restriction) on the liver function of Gezel ewes in late pregnancy. Twenty-four clinically intact ewes with an average weight of 50±3 kg used for the study. Twenty one pregnant ewes (clinically intact ewes with an average weight of 50±3 kg) were divided into 3 groups (Treatments I, II and III). The ewes in...

Modeling of future decades changes of Iran’s precipitation as basic step in management for dry farming
Human being has a very significant and pivotal role in forming the environment behavior. The growing human population, emissions of greenhouse gas, changing the earth’s surface through building dams, etc cause great changes in the environmental system. The present research is an attempt to consider the changes in the rainfall and temperature in Iran in the coming decades influenced by the increase in the level of...

Verification of the analytical equation for power penalty measurement in OXADM device
This paper presents a computational investigation of OXADM device for measuring power penalty. The OXADM are located in the nodes, which have more than two switching directions in ring networks. The function of OXADM is to flexibly switch the wavelengths among the different input and output ports. Because of the OXADM’s imperfect performance, the insertion loss and crosstalk are induced in the system. This paper...
