Background: Semen quality is affected by environmental and genetically factors. The present study aimed to determine the association of varicocele surgery and males' infertility based on semen analysis. Materials and Methods: In this case-control study, 188 men with infertility disorder in Ilam province were enrolled between May 2008 and May 2009. Semen analysis was done using the Weili Dy...
As a long-lived beta-emitting radioisotope of iodine, (129)I is produced both naturally and as a result of human nuclear activities. At present time, the main part of (129)I in the environment originates from the human nuclear activity, especially the releases from the spent nuclear fuel reprocessing plants, the (129)I/(127)I ratios have being reached to values of 10(-10) to 10(-4) in the envir...
Downregulation of microRNA-129 (miR-129) has been described in various types of cancer, however, the significance of miR-129 in lung cancer has not been investigated. The present study, for the first time, determined miR-129-5p expression levels in both lung cancer cell lines and primary lung cancer tissues and also studied the effect of miR-129-5p on the proliferation and invasiveness of lung ...
The numerical controlled oscillator has wide application in radar, digital receiver, and software radio system. Firstly, this paper introduces the traditional CORDIC algorithm. Then in order to improve computing speed and save resources, this paper proposes a kind of hybrid CORDIC algorithm based on phase rotation estimation applied in numerical controlled oscillator (NCO). Through estimating t...
The doubly-fed induction generator (DFIG) produces the reactive power to maintain its constant voltage operation. Firstly, the principle of the constant voltage control system for double-fed wind turbines is researched, and the influence on DFIG terminal voltage when the wind speed changes and the grid voltage sags is analyzed. Secondly, self-tuning PI control algorithm based on BP neural netwo...
This paper firstly show that a recent model (Tian et al., Transpn. Res. B 71, 138-157, 2015) is not able to well replicate the evolution concavity in traffic flow, i.e. the standard deviation of vehicles increases in a concave/linear way along the platoon. Then we propose an improved model by introducing the safe speed, the logistic function of the randomization probability, and small randomiza...
Slip power recovery configuration provides an attractive alternative for variable speed drives and generating systems, due to its high-efficiency and low converter rating. The core component is the doubly-excited machine. Firstly, we present a stability analysis of the doubly-excited machine with open loop voltage and open loop current control in the rotor circuit. Possibilities of open loop co...
In this paper, we describe a new design procedure for cascaded controller for electrical drives based on evolutionary algorithms. Most electric drives have two separate controllers for current and speed control, which are in general designed in two consecutive steps (firstly the current controller and then the speed one). Using a hybrid evolutionary algorithm designed to test and compare contro...
The main objective of paper is to design and implement a high speed processing system with high throughput and low complexity. We are using system on chip using AMBA bus. This high speed processing system is application specific. This system will be used for landmine detection during wars as high speed processing is need of application. Firstly input processor will be designed as per the applic...
