International Journal of Reconfigurable Computing , 2010, DOI: 10.1155/2010/697625
Abstract: We present a method for implementing high speed finite impulse response (FIR) filters on field programmable gate arrays (FPGAs). Our algorithm is a multiplierless technique where fixed coefficient multipliers are replaced with a series of add and shift operations. The first phase of our algorithm uses registered adders and hardwired shifts. Here, a modified common subexpression elimination (CSE) algorithm reduces the number of adders while maintaining performance. The second phase optimizes routing delay using prelayout wire length estimation techniques to improve the final placed and routed design. The optimization target platforms are Xilinx Virtex FPGA devices where we compare the implementation results with those produced by Xilinx Coregen, which is based on distributed arithmetic (DA). We observed up to 50% reduction in the number of slices and up to 75% reduction in the number of look up tables (LUTs) for fully parallel implementations compared to DA method. Also, there is 50% reduction in the total dynamic power consumption of the filters. Our designs perform up to 27% faster than the multiply accumulate (MAC) filters implemented by Xilinx Coregen tool using DSP blocks. For placement, there is a saving up to 20% in number of routing channels. This results in lower congestion and up to 8% reduction in average wirelength. 1. Introduction There has been a tremendous growth for the past few years in the field of embedded systems, especially in the consumer electronics segment. The increasing trend towards high performance and low power systems has forced researchers to come up with innovative design techniques that can achieve these objectives and meet the stringent system requirements. Many of these systems perform some kind of streaming data processing, which requires the extensive evaluation of arithmetic expressions. FPGAs are being increasingly used for a variety of computationally intensive applications, especially in the realm of digital signal processing (DSP) [1–7]. Due to rapid increases in fabrication technology, the current generation of FPGAs contains a large number of configurable logic blocks (CLBs), and are becoming more feasible for implementing a wide range of arithmetic applications. The high nonrecurring engineering (NRE) costs and long development time for application specific integrated circuits (ASICs) make FPGAs attractive for application specific DSP solutions. Finite impulse response (FIR) filters are prevalent in signal processing applications. These functions are major determinants of the performance and of the device

International Journal of Tropical Medicine , 2012,
Abstract: The control of Tuberculosis (TB) is a major health problem in developing countries. Annual Risk of Infection (ARI) is an index used for evaluating the programs against tuberculosis. This index shows the incidence of this infection within a society during 1 year. This study carried out among primary school students during 2 successive years in order to evaluate the results of tuberculin test (PPD) in the 1st year and to determine the variation in the 2nd year. In this study from the northwest of Iran (Ardabil), 780 primary school students randomly selected from 17 primary schools. The age was 8-14 years and mean age was 9.92±1.29. All the subjects injected tuberculin skin test (Pastor Institute 5 IU) in May 2005 and May 2006. In both tests, the results recorded after 48-72 h. PPD >10 mm considered positive. Among the subjects, 55 cases (7.1%) had positive PPD in both tests, 614 cases (78.7%) had negative PPD in both tests, in 33 cases (4.2%) PPD converted from negative (1st year) to positive (2nd year) and in 78 cases, the results were unreliable. Overall, BCG had injected 98.1% of subjects on the vaccination schedule. According to the results, with the passing of time, BCG vaccination dose not affect tuberculin test of schoolchildren. On the other hand, the conversion rate in PPD from negative to positive was (4.2%), which shows the high rate of tuberculosis in this region.

Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.714196
Abstract: Memory work is an approach developed to help us problematize the things we take for granted and as such an invitation to methodological explorations in teaching and research. By our own stories of memories and experiences we are invited to look for variety—in our own stories as well as in relation to the stories of the others—regarding content as well as interpretations. A set of techniques is developed to make this happen, in writing as well as in analyzing. Focusing on the social aspects of a story does not only imply a possibility to connect different analytical levels (micro and macro) and verify concepts and theories. It also allows us to question or specify fixed or simplified categories and concepts by making other memories, experiences and understandings visible. As such it is an approach that stimulates creativity and knowledge production in both teaching and research, to the joy of all participants. In this article it is illustrated how the approach can be used in different settings and on different themes in both teaching and research hereby also illuminating the kinds of knowledge that can be gained. Cases and detailed accounts of how the approach can be used when teaching a one-day workshop, a three-day course but also in a two-hour lecture in a regular class on BA-level are given. Examples of the use of the approach in different research projects are also presented so as to illuminate the bridge between research and teaching and how research approaches can be made into teaching approaches. The illustrations are meant to inspire further use and development of the approach so as to fit different situations and themes in teaching and research.

Polish Journal of Surgery , 2011, DOI: 10.2478/v10035-011-0047-z
Abstract: Intussusception is a curious anatomic condition characterized by the invagination of one segment of the gastrointestinal tract into the lumen of an adjacent segment. Once initiated, additional intestinal telescopes into the distal segment, causing the invaginated intestine to propagate distally within the bowel lumen. The aim of the study was to evaluate the clinical manifestation, etiology, and outcome of intussuception at atypical ages. Material and methods. This retrospective study was carried out on patients aged <6 mo or >2 yr with intussusception. Duration of study was from March, 20, 1997 to March, 20, 2008. The places of study were Imam Khomeini and Abuzar referrals hospital. Cases were classified according to age and sex. According to age, patients were <6 mo, 2-10 years, 10-18, and more than 18 years. Age, sex, history, chief complaint, clinical manifestation, sonographic findings, duration of clinical manifestation, method of treatment, outcome, duration of hospital staying, and ICU admission were studied. Data were analyzed with SPSS ver 16 (Chicago, IL, USA) and Epi-info. Results. In this study, 36 cases with diagnosis of intussusception at atypical ages, <6 mo or >2 yr, were included. From all cases, 21 cases (58.3%) were 2 through 10 years and male: female ratio was 2.26:1. Ten cases (27.8%) had history of medical condition. Eighty percent (29 cases) had abdominal pain and 20 cases (58.3%) had vomiting. Abdominal mass was found in 14 cases (38.8%). Sonography was done for 30 (83.3%) of cases and suggesting intussuception in 25 (69.4%) of cases. Intussuception was reduced by hand and performed appendectomy for 10 cases (27.8%). Bowel resection was done for 19 cases (52.8%) and radiological reduction was done for 2 cases (5.6%). Eighteen (50%) cases had anemia. Twenty-five cases admitted to ICU. One (2.8%) patient died (a 65 year old woman). Appendicitis is the most common well defined injury associated with intussusception. Conclusion. This study showed that with advancing age, incidence of intussusception will be decreased. As age increasing, rate of bowel resection will be increased. All cases with appendectomy and reduction by hand had hospital staying 3-10 days. The results of this study was similar to other studies. The most widely used diagnostic procedure for intussusception was sonography.
