In the present study, a numerical investigation has been made to predict the laminar flow and heat transfer through a rectangular channel with adiabatic, different configuration obstacles which are arranged alternately on the upper and lower walls of the channel. These walls are subjected to a constant heat flux 500 W/m2. The effect of obstacles number, and obstacles shape on the flow and heat transfer characteristics with different Reynolds number (100,200,300,400,500,600and 700) have been studied. The continuity, momentum, and energy governing equations are solved by the finite volume method. The results of this study reveal that the obstacles have an obvious effect on parameters of the flow and heat transfer enhancement. The heat transfer is improved more as the obstacle's number increase. Further that, using rectangular obstacle leads to increase heat transfer rate higher than the rest of shapes for all Reynolds number tested.

In this work we present an investigation of a complex viscoelastic flow through an abrupt expansion with expansion ratio D/d = 4, where the Oldroyd-B model was consider as a constitutive equation. The governing equations are solved using the Finite Element Method. The polymer is modeled as a monodisperse suspension of “Oldroyd-B” molecules, which provides a direct link the molecular topology and the flow properties of the melt. The branching produces an enhancement in the size of upstream vortex in creeping flows. Also was found that including inertia forces will give the intensity of lip vortex increases, while the size of corner vortex will initially decreased with growth of Weissenberg number but with more increase (We>4), the size of corner vortex will begin to increase in size. The effect arises from the differing responses in shear and extensional flows of polymer melts.
在这项工作中，我们提出了通过膨胀比D/ D = 4的复杂粘弹性流动的研究，其中Oldroyd-B模型被认为是一个本构方程。采用有限元法求解控制方程。该聚合物被建模为“Oldroyd-B”分子的单分散悬浮液，这为分子拓扑结构和熔体的流动特性提供了直接联系。在蠕变流中，分支的存在使上游涡的大小增大。同时发现，加入惯性力会使唇涡强度增大，而转角涡的大小会随着Weissenberg数的增加而开始减小，但随着Weissenberg数的增加(We>4)，转角涡的大小开始增大。这种效应是由聚合物熔体在剪切和拉伸流动中的不同响应引起的。

Endocrine disrupting chemicals (EDCs) in water have been of overworld concern due to their potential adverse effects in organisms . The objective of this study was to examine endocrine-disrupting factors in Euphrates river , in Al-Nassiryia city/Iraq. Samples from all locations were collected during autumn2016 and winter2016, extracted by solid phase method and analyzed by HPLC-UV in the wave length of 210 nm for ethinyl estradiol and 280 nm for other compounds. The results showed that presence of bisphenol A with concentrations ranging 0.001 to 0.98 μg/L and 0.09 – 5.7 μg/L nonylphenol and 2.05 – 19.9 ng/L for 17-beta estradiol. Estron was 0.1 to 54 ng/L and 0.91-6.2 ng/L for ethinyl estradiol. The concentration levels of pollutants in st.2 were higher than the st.1 and st.3. Analysis of water showed that concentration levels of pollutants were higher during autumn comparing with winter in st.2 (Pvalue ≤0.005), which may be due to the changes of environmental conditions. The widespread use of birth control pills formulated with these content of potent estrogenic chemicals appear to be the more important path for the freeing of estrogenic compounds into the aquatic environment.

This paper proposed a new smart home master control system based on Z-wave network and the TI-CC1125 transceiver. The smart home system includes lighting system, security system, smoke sensors, environment control and other equipment which are connected to a wireless communication network. Instead of having a specific controller for each system, in this paper we suggest having a master controller that monitor all systems status via sniffing their transceiver signals. Z-wave is the selected communication technology for this research. The Texas instrument lower power consumption transceiver (TI-CC1125) is used for this purpose in the sniffer mode of operation. Smart RF Studio 7 and the Code Composer Studio (CCS), both produced by Texas Instrument, are used for programming the Transceiver. The sniffed packets are displayed by the on-board LCD screen as well as the on PC application over UART interface, which can be processed later for a specific function.
{"title":"Design and Implementation of Z-Wave Sniffer on TI-CC1125 Transceiver","authors":"Ali Kareem Abdulrazzaq","doi":"10.32792/utq/utj/vol12/3/9","DOIUrl":"https://doi.org/10.32792/utq/utj/vol12/3/9","url":null,"abstract":"This paper proposed a new smart home master control system based on Z-wave network and the TI-CC1125 transceiver. The smart home system includes lighting system, security system, smoke sensors, environment control and other equipment which are connected to a wireless communication network. Instead of having a specific controller for each system, in this paper we suggest having a master controller that monitor all systems status via sniffing their transceiver signals. Z-wave is the selected communication technology for this research. The Texas instrument lower power consumption transceiver (TI-CC1125) is used for this purpose in the sniffer mode of operation. Smart RF Studio 7 and the Code Composer Studio (CCS), both produced by Texas Instrument, are used for programming the Transceiver. The sniffed packets are displayed by the on-board LCD screen as well as the on PC application over UART interface, which can be processed later for a specific function.","PeriodicalId":23465,"journal":{"name":"University of Thi-Qar Journal","volume":"68 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83190876","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}
