Reynold model is used for temperature dependent viscosity. The upper convected Maxwell (UCM), linear PTT (LPTT) and quadratic PTT (QPTT) models have been solved from this considered model. Interpretation for “velocity profile, temperature distribution, volume flow rate and average velocity” has been obtained in this case. Consequence of distinct parameters on “velocity profile” and “temperature distribution” are shown graphically and therefore the comparison is also given for velocity and temperature distribution for all the special cases of PTT by using tables.","PeriodicalId":21635,"journal":{"name":"SINDH UNIVERSITY RESEARCH JOURNAL -SCIENCE SERIES","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78440077","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}

Remote sensing data of Alos DEM of 30-meter resolution were obtained throughUSGS earth explorer official website. Shape filewas developed through the Google Earth Pro and ArcGIStechnique. HEC-GeoHMS was used to obtain hill torrents through processing tools and the stream definition was automated fixed to delineate the watershed area covering >= 75 km2.IdentifiedThe Groundwater resource into two categories of dug well and deep well. The study showed various ranges in the length of hill torrents 0.12 to 43.30 km, the depth of dug well aquifer 08.23-33.50 and deep well 91.50 to 164 meters in the region. Due to some research limitations the number 52 hill torrents, 33 dug wells and 11 deep wells were identified. Hill torrents carry runoff for the least period of rainy days, the torrential beds percolate the runoff and recharge shallow aquifers in the region, while deep aquifers recharges through adjoining watersheds. Water resourcepotential in the study area could be established by efficient heavy machinery to strengthening the torrential beds, and farms periphery bund structures, channelize watercourses, developed different ranges of ponds and reservoirs to capture floodwater, which enhance the recharge capacity of groundwater and introduce a high efficiency irrigation system in the study area. The spatial variation of water resources through modeling assessment has a major importance in the planning and development.

Ultra-wide band antenna is one of the major component of the GPR system; which is used to transmit and receive short pulse of electromagnetic nature. The performance of the GPR system in detecting buried object is mainly affected by the reflections of the GPR antenna. The reflections from the antennas itself is a basis of late-time ringing and distortion of antenna. These factors create problem in the identification of the objects. Several UWB antennas are used in the GPR system. This paper presents theoretical study for the design of ultra-wideband Bow-tie antenna as a GPR antenna. Bow-tie antenna is designed for a frequency range of 4-18 GHz. Transient and spectral behavior of the antenna is simulated. The time behavior of the antenna shows a reflected signal from the bow-tie antenna of the duration of 2.0 ns. The antenna provides a VSWR less than 2.0 and a return loss of less than -15 dB in the operating frequency range. Bow-tie antenna is then modeled and simulated in the GPR environments which includes the buried object (i.e. scatterer) and beam floor.
