Recently, various types of Solid State Fault Current Limiters (SSFCLs) have been proposed. These SSFCLs can improve the voltage quality, decrease the transmission losses, and also can enhance the distribution network stability but there are some practical problems with these FCLs. This paper proposes a modified FCL with focusing on the components optimization, efficiency improvement and reducing the cost. The suggested FCL uses a series AC reactor with controllable power electronics switches named Thyristor-Controlled AC Reactor (TCAR) which is connected in series with the feeder to limit the fault current and avoid fault current problems, which impairs overall distribution network reliability.. The influence of TCAR on the fault current is analyzed using analytical, simulation and laboratory tests. The performance of the proposed TCAR in the simple distribution network is examined. The simulation and experimental results are in a good agreement with together and show the proper operation of the proposed TCAR during the normal and fault operation modes.
This study aims at examining relationship of organizational culture and knowledge management with innovation of employees in offices of sports and the youth in Lorestan (a city of Iran). In this descriptive, correlational study, the population consisted of 100 organizational members in offices of sports and the youth in Lorestan in 2014. By using personal information questionnaire and three surveys including Organizational Culture Survey (Denison, 2000), Knowledge Management Survey (Lawson, 2003), and Innovation Evaluation Survey (Soltani, 2007), we gathered our data. Data analysis was done by Pearson\'s correlation coefficient and stepwise multiple regression(P≥ 0.05). Our findings demonstrated a significantly positive relationship between organizational culture (r=0.696), its components including involvement (r=0.700), consistency (r=0.638), adaptability (r=0.707), and mission (r=0.624) and innovation among employees of offices of sports and the youth in Lorestan. Additionally, knowledge management (r=0.471) and its components i.e. knowledge creation (r=0.286), knowledge absorption (r=0.392), knowledge organization (r=303), knowledge conservation (r=0.438), knowledge distribution (r=0.481), and knowledge application (r=0.511) were significantly and positively correlated with innovation ofthese employees.
This research aims at compiling a strategy for developing Iranian Diving & Life Saving Federation. \nThe research is an applied one concerning its goal & nature and descriptive – analytical one concerning its implementation strategy. To implement the research, first, current data of Diving & Life Saving Federation were collected from Library and World Wide Web through forms designed for this purpose. Then a Researcher Made Questionnaire was prepared with the assistance of elites and 12 experts & university professors confirmed its validity & credibility. Credibility of the questionnaire was calculated through Cronbach’s Alpha as 0.79. After that the questionnaire was distributed among the sample society consisting of 120 persons (Instructors, Path Designers, Referees, National Athletes and Directors related to Iranian Diving & Life Saving Federation). Then the data were gathered and analyzed on the basis of the descriptive statistics rules including central mean and sprawling indexes. The Friedman Test was used through SPSS Software in the area of Deductive Statistics.\nStatus of the Iranian Diving & Life Saving Federation was determined as so, on the basis of the Internal & External Factors\' Matrix.
In this paper we have studied the design of Universal asynchronous receiver transmitter (UART) by means of field programmable gate arrays like Spartan 6 and Virtex7 their component utilization and area optimization. In microcontrollers for communication purpose UART module is used for transmission of bits in serial to parallel phenomenon at the transmitter side and the vice versa at the receiver side of which they are clocked asynchronously. In this analysis we have synthesized the desirable circuit for Spartan-6 FPGA which is a 45nm technology based and Virtex-7 device which is a 28nm technology based using the Xilinx ISE tool, with programming in Verilog Hardware Description Language. Comparing these two technologies upon synthesis with respect to parameters like number of slices look up tables, GCLK (the global clock buffers), sliced flip flops and maximum frequency, it was observed that 28nm technology utilizes less area than 45 nm technology. And we have found speed has been enhanced in these devices when compared to previous version of their same family.
Fusion is an abnormality of tooth development defined as the union of two developing dental germs resulting in a single large dental structure. This irregular tooth morphology presents a high predisposition to dental caries and periodontal diseases. As a result of recurring inflammatory periodontal process such as periodontal pocket, pericoronitis and paradental cysts may develop. A rare mandibular anatomic variation is retromolar canal which is very significant for surgical procedures. Fusion of a paramolar and mandibular third molar associated with paradental cyst and also presence of retromolar canal occurring together is rare and the aim of the present study to evaluate all of them by cone-beam computed tomography.
This paper proposes a new algorithm which is a logical\nextension of the popular Round Robin CPU scheduling\nalgorithm. The Round Robin algorithm can be\neffective only if the time quantum is chosen accurately.\nEven by taking mean average of burst times as time\nquantum, the performance of the RR cannot be\nimproved beyond a certain point. However, the novel\nmethod proposed here, suggests that a priority be\nassigned to each process based on balanced precedence\nfactor. The novel method also uses mean average as a\ntime quantum. Experiments are conducted in order to\nmeasure the effectiveness of this novel method. The\nresults clearly showed that EPSADTQ is superior to RR\nand PSMTQ and its variants. EPSADTQ resulted in a\nsignificant reduction of the no. of context switches,\naverage waiting time and average turnaround time.
Objectives: Young athletes usually engage in strenuous physical activity to which they are unaccustomed, usually land up in a phenomenon called Delayed Onset of Muscle Soreness (DOMS). This will decrease the performance of the athletes. There is a lack of consistency in the selection of duration and intensity of the exercise by athletes. There are dearth of studies which have been done on relationship between intensity and time duration of the onset of DOMS.\nMethods: A convenience sample of 45 male subjects with the mean age of 24.8 ±1.1years and BMI of 23.4±2.3 participated in the study. Subjects were randomly allocated in to three groups A, B and C (n=15) and was undergone a standard eccentric exercise protocol at three different intensities i.e. 75%, 50% and 25% of 1Repaetation Maximum (RM) respectively. Study outcomes were measured by Visual Analogue Scale (VAS) was used to assess muscle soreness at time of onset of soreness (ToO) and three subsequent days (DoO). Total duration of the study per subject was for 5 days.\nResults: All three groups showed occurrence of pain on post exercise, although group-C analysis showed non-significant result in the pain perception than group A and B (p>0.05). When compared the ToO and DoO between group A and B analysis showed non-significant whereas when between group A and B compared with group C showed significant result (p<0.05). \nConclusion: The result of the current study concluded that weight training for a beginner can safely start with 25% of 1RM intensity without anticipating of setting DOMS. Study also observed that higher intensity group will have faster onset and larger duration of DOMS than the other lower intensity groups.
