Geosmin contamination in water is a leading cause of odor related complaints to water companies in UK, tainting water with an earthy smell that is detectable by humans in quantities as low as 4 nanograms per liter. Current Geosmin detection methods depend on lab-based equipment, requiring samples to be collected and transported before Geosmin can be tested. This research presents a novel method for the detection of Geosmin in water using Microwave spectroscopy capable of detecting differentiating between four levels of Geosmin contamination: 5 ng/L, 10 ng/L, 0.5 mg/L and 1 mg/L as well as control samples. Frequencies within the 5.4 GHz to 5.9, 6.4 GHz to 6.5 GHz and 7.2 GHz to 7.5 GHz ranges showed significant separation between the sample classes.

This paper focuses on a case study of a fourspan continuous prestressed concrete box-girder bridge that developed extensive damages to the deck and webs in two successive spans due to an explosion by a trailer charged with high explosive materials. The eight cell box-girder bridge is connecting Baghdad city with the other southern provinces of Iraq. The bridge is 166 m long, the deck and soffit slab widths are 20.5 m and 16.3 m, respectively, and the overall crosssectional depth is 1.30 m. The importance of this structure from economic and traffic points of view has made it impossible to think of the total replacement. Accordingly, the possibility of the replacement of the four spans was ruled out due to the tedious nature of the process, the time and cost. The main two goals of the study were how to keep the prestressing effect and how to compensate the continuity in the nondamaged spans. To achieve these goals, mechanism for restraining was implemented directly at each cross-sectional web of a span at a pier location. Also, a strengthening of the two non-damaged spans of the box-girder bridge was performed by installing a series of steel plate strips at the top concrete fibers of the deck slab and bottom concrete fibers of the soffit slab. This approach improved the stress distribution in the deck and maintained the original load resistance mechanism provided by the prestressing arrangement in the box-girder.

An electroencephalography (EEG)-based wheelchair control system (EEG-WCS) can serve the disabled in their life activities, particularly in assisting them in moving freely. Given the recent evolution of new technology, the disabled can move freely without requiring aid from others and communicate with their community by using advanced smart wheelchairs. In this paper, an EEG-WCS algorithm is proposed for controlling wheelchair movements based on EEG signals. Based on microwave radar sensors, the algorithm allows the wheelchair to avoid obstacles during movement. The EEG-WCS consists of an electric wheelchair, Emotiv INSIGHT brainwear to read brain signals, a DC motor driver for controlling the velocity of the wheelchair, microcontroller, DC motor, and batteries. In addition, the C language can be used to program the system’s controller (microcontroller). Moreover, we classify, explore, and highlight the recent solutions for such systems and compare them in terms of control method, algorithm used, sensor type, accuracy, and response time.

In order to define the location of any electromagnetic transmitting source, two or three directions of arrival (ƒÆ, .) estimators are needed to provide two or three different directions for coordination. In the last two decades most of research works are focused on Multiple Signal Classification (MUSIC), and Estimation of Signal Parameters using Rotational In-variance Techniques (ESPRIT) techniques, since they provide high (AOA) estimation accuracy. Most of researcher assumed the arrays are linear and planner formed from isotropic elements. In practical case, the array antennas are formed from short or half wave dipoles; these types of element lead to many difficulties, since the field pattern are no longer isotropic. They have a pattern directivity function of spatial angles, so by using short dipoles as linear array element, it is so difficult to have a fixed output SNR for all angles of arrival for estimated signals. In this paper, we introduce a new approach to overcome this problem and by this approach we get a fixed output SNR regardless arriving angles of received signals. The proposed approach offers a simultaneous estimation for output SNR and AOA with voice channel based on a practical field scenario (battle field condition) by using phased adaptive array system with new array elements configuration and algorithm. A linear phased adaptive array element is shifting by predetermined angle (ƒ¿), which is depending on the number of array elements and on a spatial span that must be covered. A modified LMS algorithm is used to make adaptive array antenna works as angle of arrival (AOA) estimator rather than noise and jammer canceller. The results show that the proposed system can accurately and simultaneously estimate AOA as well as the output SNR for all arriving angles and also provides voice channel for listening which is needed for electronic warfare activities. The results show that the estimated output SNR level is fixed over the coverage spatial span regardless the direction of arrival of received signals. By using parallel linear array elements [without shifting (ƒ¿=0)] the output SNR level no more fixed and it directly depends on the arriving angle of received signal. Finally, the theoretical analysis and simulation results show that there is an interesting relationship between largest Eigenvalue ƒÉmax of orthogonalized received signals covariance matrix ƒ³xx and the output SNR of estimated signal which is (ƒÉmax=SNR+1).

The article deals with some aspects of creating comfortable conditions that ensure optimal human performance and preservation of his health when using exoskeletons. In recent years, gravity compensators have become widespread in the design of exoskeletons, which increase the efficiency of such equipment. Further improvement of exoskeletons involves the development and creation of an optimal system of attachment of the compensator to the bearing frame of the exoskeleton. The article is devoted to the development of a method for determining the parameters of the fastening system based on modeling and studying the kinematics of motion of the exoskeleton links when performing various movements. Practical recommendations are given on the creation of a linear compensator installation system that provides comfortable conditions for the operator.

The networks of the ground meteorological stations in several basins are most often insufficient and inadequate, which causes a paucity in the rainfall data, and these are regarded as the basic inputs for the models of water resources. Therefore, a good alternative information source is required. This paper gives a report on the applicability of using satellite derived precipitation data, which is essential for the simulation models of the Galal-Badra basin that lies in both the Iranian and Iraqi regions. Two scenarios to be validated were used, first by using the Tropical Rainfall Measuring Mission (TRMM) to generate the satellite precipitation data for the 1998 -2009 period and employ that data to compare with the data from the rain gauge stations available in the basin. The second was accomplished by using the Prediction of Worldwide Energy Resource dataset from the National Aeronautics and Space Administration (NASA–POWER) for the 1994-2005 period. The validation of the techniques was tested statistically by using coefficient of determination (R^²) and slope besides the correlation coefficient (r) and the results obtained were concurrent, as (r = 0.95; R^²= 0.83 and the slope = 0.7) when using the TRMM; however, these values are lower when NASA-POWER is used. Both results suggested a positive correlation between the satellite and observed data, and thereby satellite data was sufficient for simulation of the different hydrological processes.

Agriculture is considered the economic basis of countries around the globe, and the development of new technologies contributes to the harvesting efficiency. Autonomous vehicles are used in farms for seeding, harvesting and tasks like pesticide application. However, one of the main issues of any plantation is insect pest and disease identification, essential for pest control and maintenance of healthy plants. This work presents and compares three methods for insect pest identification using computer vision: Deep Convolutional Neural Network (DCNN), as a baseline; Hierarchical Deep Convolutional Neural Network (HD-CNN), in order to improve prediction of similar classes; and Pixel-wise Semantic Segmentation Network (SegNet). They were tested for two kinds of culture, soybean and cotton. SegNet outperformed both approaches by a wide margin: the methods had respective accuracies of 70.14% DCNN, 74.70% HD-CNN and 93.30% SegNet.
