Study design: This study was designed to reveal how the monthly mean of the daily average, monthly mean of daily maximum and monthly mean of the daily minimum temperature of all divisions covering all hydrological units of Bangladesh changed historically. It is also designed to forecast the all type of temperatures from up to 2050 using Box Jenkin’s algorithm in IBM SPSS. Place and Duration of Study: This study was conducted within the time period from December 2015 to December 2016 under the Department of Civil Engineering, Dhaka University of Engineering & Technology, Gazipur, Bangladesh. Methodology: At first the daily average, daily minimum and daily maximum temperature for the time period 1975 to 2014 of 13 stations, covering all hydrological units of Bangladesh, were converted in to monthly mean and then graphs of individual months were plotted and analyzed afterwards. To infer the historical temperature variations clearly over the entire time period, histogram of the decadal averages of the each type of temperature of the individual months were also plotted. Finally, the monthly records were forecasted up to 2050 by a time series model using Box Jenkin’s algorithm in IBM SPSS. Results: Based on the historical and projected temperature, this study revealed that winter became colder especially in January and the summer got hotter over the time which may continue in future. By 2050 the maximum temperature may rise by 1.50±0.3°C in summer, average temperature may rise by 1.0±0.3°C and minimum temperature may vary by -0.8±0.3°C in winter.. Conclusion: This study concludes that winter may get colder in the northern part as well as some southern part of Bangladesh and reverse may suit for the summer where January and April would be the coldest and the hottest months respectively in future. By the year 2050, the average temperature may rise by 1.0±0.3°C and the maximum temperature may lead to 1.50±0.3°C, whereas the minimum temperature may vary from -0.8°C to 0.2°C. Overall, Bangladesh would experience a comparatively warmer weather in the coming decades.","PeriodicalId":91221,"journal":{"name":"British journal of applied science & technology","volume":" ","pages":"1-13"},"PeriodicalIF":0.0,"publicationDate":"2017-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42972118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Every vital section of the economy ranging from clothing, agriculture, packaging, automobile, medicine, electrical and electronics have been virtually revolutionized by application of plastics. The challenge of the disposal of these plastics after use is what this study seeks to address in part. Low density polyethylene (LDPE) and polyethylene terephthalate (PET) plastic wastes were blended with bitumen as binder for road construction as an effective and valuable means of disposing these wastes, employing marshall hot-mix design. 15% and 30% w/w LDPE and PET wastes of total binder required for the asphalt design were incorporated at 6% optimum binder content. The polymer modified asphalts (PMA) were tested for marshall stability and flow. At 15% w/w LDPE, the stability and flow values are 819 kg and 3.6 mm, respectively, while at 30% w/w LDPE, the stability and flow values are 643 kg and 4.1 mm, respectively. Similarly, at 15% w/w PET, the stability and flow values are 737 kg and 3.3 mm, respectively, while at 30% w/w PET, the stability and flow values are 707 kg and 3.5 mm, respectively. These results are in agreement with the “general specification for roads and bridges, vol. II (1997)” of the federal government of Nigeria, which specifies a minimum of 350 kg and Original Research Article Dalen et al.; BJAST, 19(3): 1-7, 2017; Article no.BJAST.31141 2 2-4 mm for stability and flow, respectively.

Albared, Tareq Al-Moslmi","doi":"10.9734/bjast/2017/29754","DOIUrl":"https://doi.org/10.9734/bjast/2017/29754","url":null,"abstract":"As a morphologically rich language, Arabic poses special challenges to Part-of-Speech (POS) tagging. Words in Arabic texts often contain several segments; each has its own POS category. The choice of the segmentation level or the input unit, word-based or morpheme-based, is a major issue in designing any Arabic natural language processing system. In word-based approaches, words are used the atomic units of the language. In this case, composite POS tags are assigned to words. Therefore, large amounts of training data are required in order to ensure statistical significance. They suffer from the problems of data sparseness and unknown words. In case of morpheme-based approaches, morpheme components of words are used as the atomic units. This, however, results in high level of ambiguity rate and also small size of context for resolving such ambiguity because the span of the n-gram might be limited to a single word. This paper compares and contrasts the morpheme-based and word-based statistical POS tagging strategies. This paper evaluates the tagging performance of three statistical models, namely, the Arabic HMM POS tagger with the prefix guessing models, the Arabic HMM POS tagger with the linear interpolation guessing models and the TnT tagger, given training data from both morphemebased and word-based tokenization levels. It also studies the influence of each choice on the Original Research Article Ba-Alwi et al.; BJAST, 19(1): 1-10, 2017; Article no.BJAST.29754 2 tagging performance of the Arabic POS tagging models, in terms of the tagging accuracy and the time complexity. In addition, this paper also evaluates the tagging performance of several stochastic models, given training data from both segmentation levels. Results show that the morpheme-based POS tagging strategy is more adequate for the purpose of training statistical POS tagging models as it provides a better overall tagging accuracy and a much faster training and tagging time.","PeriodicalId":91221,"journal":{"name":"British journal of applied science & technology","volume":"19 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2017-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41652906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The carbon density of different tree parts is not often measured directly, but generally assumed to be 50% of dry weight. In this study we try to analyze those assumptions and determined the effect different regression equations on carbon sequestration for Tectona grandis , Vachellia nilotica , Madhuca indica , Dalbergia sissoo . The present study aims to estimate the above-ground biomass (AGB) and carbon sequestration in 18 sampling plots of 30 × 30 m 2 size, at different sites in northern plains (Uttar Pradesh) India. Two regression models were used for each species; one using DBH only (Method 1) and the other using DBH and height (Method 2). The best fit models were chosen on the basis of highest R 2 . The DBH, AGB and carbon density yielded a positive relationship for all the species. Apart from Model D1h, all R 2 values for models developed with our data (both DBH and height) were above 99%. The R 2 values for models developed with DBH only were below 90%, least for model M1 (77.6%) The co-efficient for DBH was not significant in Model D1h and M1h, but the co-efficient for DBH and height was significant at the 5% level of significance for all other coefficients in all other models. The estimated stem AGB was maximum for Tectona grandis with 376.2 and 355.63 t/tree with carbon sequestration of 621.25 and 587.50 kg/ha for the equation T1 and T2H respectively; whereas minimum AGB was recorded for Dalbergia sisoo with 221.55 and 211.58 t/ha and carbon sequestration of 362.93 and 349.65 kg/ha. The AGB and carbon sequestration estimation obtained in this study represents a more realistic picture of biomass of region.","PeriodicalId":91221,"journal":{"name":"British journal of applied science & technology","volume":" ","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2017-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46787730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The implanted glucose sensors, for example, shall be built small enough to allow implanting it inside the patients' body [1] to indicate the readings easily. It grants the patients the ability to read data simply through a receiver located out of the body. However, there is a problem in most of these sensors in providing them with the necessary power by using traditional chargers because any direct contact with these devices is impossible. Therefore, scientists and researchers investigate new solutions and methods to maintain transferring enough power to charge the battery of the sensor. Among all of these methods, the inductive coupling proves its ability in transmitting the power wirelessly to the application with high efficiency. This paper presents a wireless charging system to transfer the power from an external charger to an implanted device based on the inductive coupling. It discusses different considerations and possibilities in designing and implementing the proposed charger to provide enough power to the largest possible distance.","PeriodicalId":91221,"journal":{"name":"British journal of applied science & technology","volume":" ","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2017-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49297463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
