This filter has some attractive features that make it more efficient than other types of filters. One of these features is its sufficient linear phase in the passband, thus yielding a perfect reconstraction condition. Therefore, it is not required to cascade the designed filter with an all-pass filter for correcting the phase distortion. The coefficients of the designed filter are achieved by simulating the FIR response suggested in [1]. A least square method solution is used in such simulation with a genetic-based algorithm. A simplified structure for the designed filter is accomplished with less-complex realization. 50 records of European ST – T ECG database is classified into four classes (Normal, Left Bundle Branch Block (LBBB), ST segment elevation, and Left Ventricular Hypertrophy (LVH)). By applying the designed filter coefficients into neural network classifier, the results show that the accuracy of the classification process is 95.9 %.","PeriodicalId":339890,"journal":{"name":"AL Rafdain Engineering Journal","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121461768","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}

Administration building of University has an important symbolic value through its main function and responsibility that includes managing of all components of the campus. The relationship between visual organization properties of administration building of University and the building location represents phenomena that lacks adequate research endeavors, despite its importance in organizing Campus site. So there is a need for a clear and precise vision of this relationship. Four universities were selected as case studies, include designed university as Baghdad University, and accumulatively grown universities as Mosul University, Cairo University and Kufa University. Visual analysis and space syntax approach were applied to determine and compare the visual attributes of administration buildings of Universities using relevant softwares.

This hybrid phenomenon was named as Media Architecture. Over time , Media Architecture involved in numerous applications and had a wide range of architectural and urban activities , at the same time , different display technologies and numerous manifestations were appeared. The emergence of these display technologies were accompanied by new specific problems and challenges from several design aspects , these challenges were different from one display technology to another which required more studies and researches. This study deals with comparing different display technologies according to specific design characteristics (integration , flexibility , lighting and visual comfort , and media facade shape ). This study concentrated particularly on the application of Media Architecture in exterior building facades and electronic display technologies that change their appearance by use of color and light , this required a comprehensive classification to these technologies depending on the previous studies in line with the determinants of this study. The study showed variations between some of these display technologies in accordance with the design characteristics , and similarities between others. Number of recommendations was drawn in this study considering the possibility of applying this approach in our traditional architecture in future, and design indices that must be taken into consideration in order to avoid their disadvantages.","PeriodicalId":339890,"journal":{"name":"AL Rafdain Engineering Journal","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130825897","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 study aims to find out an equilibrium point of the transportation system at the intersection of the demand curve with supply curve, which represents the cost of services to be subsidized and availability of facilities on the network. Methodology started with collecting data, which includes statistical information for the community for the purpose of sample size and sampling process. The distributed questionnaire forms that was designed to gather information on trips and the knowledge of the properties of trip characteristics was done. Then cost was found about the demand curve calculated operating costs for vehicles, in addition to the cost time and cost environmental impact. Either curved processing evolved to include the cost of the vehicle and the cost of investment and maintenance, and cost of construction of the road in addition to the time savings .Statisticalanalysis was employed to find the correlation between variables. Linear regression between the independent variables and the dependent variables were identified as the most influential independent variables in addition to the best equations and mathematical relationships representative of the cost and demand processing. Research has come to several important conclusions to improve transport with the modes used .The proportion of public transit users are (38 %) compared with the majority of users of taxis by(43%), and finally representing users of the passenger car user about (18%) of the total sample , the representing students ratio (75.8%) of the users of the bus , also obtained data vehicle occupancy according to each mode. The final results show that the equilibrium point for each person is 1.0 $ for PC with average travel time = 35 min, and 0.6 $ for taxi with travel time = 60 min, and 0.32$ for small bus with travel time = 105 min, finally for large bus =0.085 $ with travel time = 75 min. key word: Travel Demand, Interview Survey Form, Average Vehicle Occupancy(AVO), Travel Supply, Equilibrium point. أ :ملتس 9 – 3 2014 :لبق 15– 3 2014 Al-Rafidain Engineering Vol. 23 No. 3 June 2015 66 لا : ةمدقم ةنیدملل ةلماشو ةرمتسم طیطخت ةیلمع دوجو مدع ةجیتن ةریثك لكاشم نم يناعی لصوملا ةنیدم يف يلاحلا لقنلا ماظن نا ةفاضلإاب ىلع تانیسحت يا دوجو مدعو ماعلا لقنلا تامدخ راسحنا عم ةیصخشلا تابكرملا مادختسلا عراستملا ومنلا ىلا م اھریغو ومنلا اذھ باعیتسا ضرغل قرطلا ةكبش ن بابسلأا ىلاو ةنیدملا مومع يف لقنلا تامدخ يدرت ىلا ىدا اذھ لك ، يرورضلا نم ھناف اذل ،ةرفوتملا قرطلا ةكبش ىلع مئاد ماحدزا ثودح ءارجإ ةفرعمو لقنلا ةكرحل طیطخت بابسلأا اھنم دحلاو لكاشملا هذھ لثم ىلا ةیدوملا و كلذ .ماع لكشب لقنلا تامدخ نیسحتب ا ةقطنم دیدحت مت ةنیدم يف تلاحرلا دیلوتو بذجل قطان","PeriodicalId":339890,"journal":{"name":"AL Rafdain Engineering Journal","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124776970","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}

It enables many scientists to understand different phenomena. However, there are many highspeed phenomena that cannot be imaged using a commercial non – scientific cameras due to their low capturing speed compared to the phenomenon's. Such phenomenon, needs high-speed expensive cameras. Some of those phenomena can be monitored if the imaging speed of the current commercial cameras is slightly increased. Consequently, it is possible to increase the speed of the video recording for a commercial cheap camera using crank and piston mechanism. A phenomenon faster than the speed of the current commercial cameras had been created and captured with the aid of the present enhancement. Two cases are compared. In the first case, the phenomenon was at a speed faster than the imaging capability of the camera and without using the present mechanism. In the second case, the phenomenon speed was kept constant but the camera is now fixed on the piston. As expected, the video capturing process enhanced and the captured images are seen to be clearer by means of a visual qualitative (mere eyes) observation between the images of the two cases.","PeriodicalId":339890,"journal":{"name":"AL Rafdain Engineering Journal","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123507957","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 analysis of the soil types was conducted in the laboratory of Civil Engineering, University of Mosul. This analysis revealed two types of soils : clay and mixed, The material of the draw-bar and its mechanical properties were obtained. Then the stresses generated in small scale model were obtained using the finite element analysis using the “Ansys Release 14.0” program. Three dimensional stresses together with the equivalent Von-Mises and principal stresses have been obtained. The percentage deformation in the x,y and z direction were also obtained. During the operational stage, the stresses were measured using a number of electrical resistance strain gauges type PL-15-11 fixed on both sides of the draw-bar while the tractor was driven in two different soils at varies speeds (2.39, 3.37, 6.35) km/h. It was observed that the stresses were higher in clay soil more than those in a mixed soil due to the different composition in soil this will create different resistance in both types of soil .
