The accumulation of sediment in the bottom of the dam is one of the major causes contributed to dam failure. This in turn creates risks of flooding for villages and cities below it. The aim of this research is to investigate the output of the bathymetric contour map of the bed of small Earth dams in Duhok at three different locations (Kashkan, Zawita and Skreen) as well as to determine the volume of accumulated sediment for each one at different periods of establishment. In addition, a comparison between the current statuses and the design life of each one was achieved. Both vertical depth and horizontal position measurements are implemented using two methods. The first one is the manual and direct method using lead line rope, weight, total station and DGPS for data collection in Zawita and Kashkan reservoir. While, the second method used the Acoustic Doppler Current Profiler (ADCP) integrated with the Global Positioning System (GPS) to record both vertical depth and horizontal position measurements automatically in Skreen dam. The ADCP was calibrated for adjusting the axes (heading, roll and pitch) before collecting data. The data of ADCP were processed and analyzed using River Surveyor Line software and the bathymetric contour map of the selected reservoir's bed was created using AutoCAD civil 3D software. Also, the volume of sedimentations of each selected Earth dam was calculated from the difference between the created topographic surface of the reservoir bed and its original one. The results show that the volume of the sedimentation in kashkan reservoir is about 13810 m3 for the period of 2009 to 2018, Zawita reservoir is about 4449 m3 for the period 2010 to 2018, Skreen reservoir is about 4608 m3 for the period 2009 to 2018, and the design life of each one estimated by state was approximately similar to the finding of this research.

Root Mean Square (RMS) delay spread and path loss are two important parameters for any wireless channel characterization, and the relation between them was also under investigation for different signals. In this paper, the investigation of the dependency between the RMS delay spread and path loss was performed for the case of outdoor ultrawideband (UWB) channels with a frequency of 3.1–5.3 GHz. Both parameters were calculated based on measured channel impulse responses (CIRs), where PulsON 410 transceivers have been used for these measurements. Then analyzing the correlation coefficient between the obtained RMS delay spread and path loss values was achieved. Results show that there is a fluctuated positive linear correlation between the two parameters, where the maximum correlation value was 0.7675 reflecting higher correlation in comparison to the lowest value of 0.2951 in another measured channel. The scattering environment has a major effect on the relation between the parameters and consequently led to the fluctuation in the correlation properties.

Epoxy resin is of the most used materials in the field of insulating purposes such as in high voltage applications. In order to create an enhanced material with new properties, epoxy resin can be processed by using different fillers. In this paper, microwave power absorption evaluation of Micro-particles CuO filler reinforced epoxy composites is investigated. CuO metal oxide loadings were taken in four different percentages as (5%, 10%, 15%, and 20%) of the full sample size. Samples were casted in a square shape of (10 cm) side length along with four different thicknesses stated as 1mm, 2mm, 3mm, and 4mm for each loading value. Within an x-band frequency range of 8-10 GHz, the objectives of this paper were examined to determine the amount of microwave power absorption when each loading value is tested with its four different thickness values taken in consideration. The epoxy resin samples were prepared and tests were done to measure the microwave power absorption for each sample in the x-band frequency range. Generally, it has been found that the microwave power absorption is proportional to the thickness value whether it was a pure epoxy composite or a reinforced composite. Moreover, the test results revealed that the case of the (5%) CuO metal oxide filler is significantly related to the maximum power absorption when compared to other loading percentages. The obtained results provided information about the influence of the CuO filler on the insulating property of the non-filled epoxy specimens. Therefore, this composite could be regarded for applications where absorbing microwave energy is of importance and utmost necessity

The photo-catalytic degradation of Toluidine Blue dye (TB) in aqueous suspension solution has been studied utilizing fluorescence light and using Zinc oxide (ZnO) as a semiconductor at variety working factors. The studied parameters were concentration of dye, semiconductor dose and the influence of pH. The result shows that expanding of ZnO dose from 20 to 60 mg/L increases the removal rate of TB dye. On the other hand, the adding of concentration from 5 to 15 mg/L show negative effect on the rate of photo-degradation. It has been denoted that the percentage of dye degradation come to the peak value at high acidic medium. 11 % of TB dye was adsorbed, in dark condition, by ZnO. In addition, the kinetics of degradation has been examined and the degradation was found to take after pseudo-first order kinetic model.

Earth stations elevation angle of antenna have to be established in order to communicate with satellites. In spite of crucial impairments in the uplink and down link of satellite communication between earth station and satellite such as noise, rain and atmospheric attenuations still earth station elevation angle is a key limiting factor to specify the communication link budget. In this paper, comparative study of satellite communication attenuation resulting from earth station elevation angle for geostationary and non-geostationary satellite system is presented. The present of free electrons in ionosphere is the impact factor to attenuate the radio wave when the high frequency radio waves penetrate it. Using MATLAB, the results report that the minimum elevation angle is about 5 ͦ but this makes negligible difference to the maximum value of transmission path when θ=0.

Date palm (Phoenix dactylifera L.) is one of the most important and the oldest crops in Iraq. It is suffered from degradation due to various economical and numerous military conflicts. In this paper, a different method based on the Landsat-8 images has presented which is used to map the region of interest and to estimate dates palm trees. This method based on a Least Square Model (LSM) for statistical relations between different spectral indices (NDVI, EVI, NDMI) and tasselled cap parameters with in situ data. As a result, the best developed model was produced using fourth component of tasselled cap transformation with a correlation of R2 = 0.95 with in situ data. Thus, the results show that the Landsat-8 images are useful to estimate and monitor date palm area with high accuracy. This result is encouraging to estimate other parameters that concerned to the date palm.

In this paper, a system for face tracking and recognition in a video sequence is proposed based on KLT (Kanade-Lucas-Tomasi) tracker and 2DPCA (Two-Dimensional principal Component Analysis). Before using KLT algorithm for tracking faces, Viola-Jones face- detection-algorithm is applied to-detect all faces in the image or video sequence. KLT tracks face objects after being detected in the consecutive frames and sustaining long-term- tracking when faces come in/out. Face features are captured and selected using 2DPCA technique which is applied as feature extraction in order to eliminate noise and recognize faces more efficiently using a distance classifier. Face94 dataset and images captured by computer webcam are-used-to test the proposed system. Experimental results-show-that Viola-Jones algorithm is efficient when detect front faces. The KLT algorithm is tested to track faces using ten different videos captured by computer webcam. KLT is successfully applied and is able to track multiple faces even when the detected face turns left or right. Finally, 2DPCA is successfully applied and is able to recognize faces in both Face94 dataset and computer webcam video sequence.

Recently, the interest of most researchers is to find ways to design for biomaterials with certain specifications. The proposed research introduces a new design for an arithmetic circuit which process signed-digit number by adopting conversion the input rules into an array of a strand of DNA according to a specified output for each case. In other words, gates are designed using DNA strand while the inputs are designed depending on molecular beacons (MBs). The MB is a single strand of DNA that is basically in a stable state which consists of two regions, the loop, and stem. The MB consists of 25 nucleotides, where the stem region consists of 10 nucleotides, five on each side and each side is complementary to another side. This work is divided into two parts, each part represents the code for one of the inputs. Also, each code of the sign numbers (−1, 0,1) and its complement has its own predesign pattern. Three of these pattern numbers represent inputs, while the other complement three patterns represent gates. To design the gates we start from the top and when finishing the specific value we return from the bottom and vice versa to avoid the similar design and also to make the gates take the least number of DNA strands. The outputs of each signed digit (−1, 0, 1) are indicated by optical color lights red, no light and green, respectively. The simulated results for two 4-bit signed digit number for three steps addition operation show the correctness of proposed design. The addition process is executed in parallel, so the length of the number does not exceed the calculation time.

Currently, the main problem in DNA Microarray is classification due to the thousands of numbers of genes together, and this huge number of genes can make the classification task very difficult. Therefore, feature selection is a very important task for gene classification. This paper presents a new model which uses a Cuttlefish Algorithm (CFA) to select the most informative features, while K-Nearest Neighbor (KNN) is used to measure the quality of the selected features that are produced by the CFA. Eight datasets are used to evaluate the performance of the proposed model and compared with the performance of four well-known existing classification techniques such as KNN, DT, Hidden Markov models (HMM), and SVM. The obtained results show that the proposed technique outperforms these existing techniques in five datasets among eight datasets.

The obtained results show that the proposed technique outperforms these existing techniques in five datasets among eight datasets.","PeriodicalId":144020,"journal":{"name":"2018 International Conference on Advanced Science and Engineering (ICOASE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128983909","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}
