In this project, method of designing of high gain and mutual coupling reduction is proposed, which can be done by antipodal Vivaldi antenna (AVA) for 5G applications. For the reduction of isolation between the antenna elements, the antennas are not placed adjacent to each other because they have a chance of absorbing the energy which is to be transmitted. The proposed AVA comprises of 2 x 1 multiple input multiple output (MIMO) antenna elements. The antenna parameter enhancement techniques used in this design are corrugation and circular slots. The antenna dimensions are 50mm x 48mm x 0.8mm. Here, we use corrugation and circular slots method, as to increase the gain than previously designed antenna. The maximum isolation of antenna is achieved is 37dB and gain is improved in the desired range. The simulated gain is in the range of 7.1-14.4 dB in the frequency band of 20-30GHz.

Cooperative robotics is very different from working on a single robot before. Cooperative robots can perform tasks that were previously impossible with a single robot. This robot research can be applied in computer science, artificial intelligence, and electrical engineering. This research aims to deal with tasks that are difficult or impossible to perform with a single robot. For this purpose, we propose a Se-Re (Search-and-Rescue) algorithm. In addition, the proposed algorithm is designed to allow multiple robots to collaborate in the area of work. Robots use wireless communication to collaborate and are organized in groups, which create environmental maps and share data with each other. The robot uses the shared area map to create a global map. Using this information, the robot does not revisit the previously visited area. The proposed algorithm can be applied both indoors and outdoors. Indoors can be used in general buildings as well as livestock housing, and outdoors can be used for landmine removal, human search, and rescue.

In recent times, the need for concrete steps to be taken in the adaptation and mitigation of the effects of climate change has taken the centre stage in development discourse. However, there is a scarcity of empirical studies on the extent to which built environment professionals, especially in a developing country like Nigeria are aware of the various climate change mitigation and adaptation strategies. This study examined the level of awareness of climate change adaptation and mitigation strategies amongst built environment professionals in Lagos, Nigeria. The data were sourced through a cross-sectional survey of 71 respondents including, architects, builders, town planners, estate managers and quantity surveyors in the study area using an online questionnaire. The data were subjected to descriptive statistics and the result shows that the built environment professionals identified the main causes of climate change to include the use of fossil fuels in industrial production, automobiles, and generation of electricity. Also, the major effects of climate change were flooding and excessive heat, while the top three adaptation and mitigation strategies greening/planting trees, enforcement of building guidelines and the use of energy-efficient technologies. This study implies that the built environment professionals are very much aware of the existing climate change adaptation and mitigation strategies but there is an urgent need to internalize them in the production and management of the environment in Nigeria.

Corrosion is described as material’s destruction or deterioration because of reaction with its surrounding environment. This type of degradation represents a tremendous economic loss since so much value of loss being described. Mostly, in petroleum industry, mild steel are still the most commonly used metal to build structures. However, acid which is hydrochloric acid has been used as acidizing operation since its advantage over other mineral acid. This may cause mild steel structure susceptible to corrosion. This project is about the study of the rate of corrosion on SMAW and GMAW welded mild steel with different time of exposure. The comparison of f these two type of welded joint were subjected for microstructure analysis using SEM/EDX. Welded mild steel were prepared using SMAW and GMAW process with dimension of 100mm x 50mm x 6mm. Then, samples were inspected using NDT technique using magnetic particle testing. After that, the samples were immersed in 6 mol of HCl acid. Then, the corroded samples were cross-sectioned and were examined using SEM/EDX. The results show that, the rate of corrosion on SMAWwelded mild steel is higher compared to the GMAW welded mild steel. As the duration of exposure increase, the weight loss also increased as well as the value of the corrosion rate. This results were supported by the MPT showing that the flaws and defects on the SMAWwelded mild steel might be the cause that act as a stress raiser and thus, enhancing the corrosion degradation.

Welding is a fabrication or sculptural process that joints the materials, usually metals or thermoplastics, by inducing fusion. It is as distinct process from lower temperature metal-joining techniques such as brazing and soldering, to high temperature welding process and this process keep the base metal from melted. In addition, to melt the base metal, a filler material is typically added to the joint to form a pool of molten material that cools at room temperature, forming a joint that is usually stronger than the base material. Pressure may also be used along with heat, or by itself, to produce a weldment. The current study presents the effects of distortion that occurred in single-V and single bevel welded mild steel. It also includes the macro and microstructure analysis, mechanical properties and also the consumable usage along the time needed to complete the bevel and welding process. As a result, single- V is way more safe and reliable to use to withhold large load compare to single bevel.In term of financial, single bevel way more ahead.

Weld repair usually comprises of mechanical removal of weld part and redisposition of the filler wire using the same parameters. The defect may be removed by carbon arc gauging and grinding or machining. The strength and the microstructure of the material will changed when the repeated weld repair is applied to the material at the same area. The purpose of this study is to compare and identify the angle of distortion, hardness, and tensile strength and bend strength and to analyze the macro and microstructure between repairing method using carbon arc gauging and mechanical grinding process with the same number of repairing sequence. The result proved that repairing A36 steel increased the strength of the material itself but the ductility was decrease when the number of repair increases. It can be concluded that, the repair using carbon arc gauging can’t be applied to repair weld joint for material because it’s more significant to change the material process compared to mechanical grinding. Overall, the mechanical grinding technique is the most suitable practice which can serve as the suitable method for repairing the weld defect if the repaired focus area received high impact loads.

Airborne Early Warning (AEW) systems are deployed for getting surveillance information on airborne enemy targets. Electromagnetic sensors such as Radars are integrated on airborne platforms for collecting such information. Maritime Patrol Radar (MPR) is used for surveillance of sea surface for various types of ships and low flying aircraft. The antenna of MPR is belly mounted on typical turbo prop aircraft and protected from environment with a cover called Radome. Airborne radomes are electromagnetically transparent. The radome installation introduces additional drag which will reduce the range of the aircraft. To minimise the drag due to installation of radome, the profile has to be stream-lined or optimised with CFD analysis for certain operational points of aircraft flight. Design of radome is multidisciplinary effort involving Aerodynamics, Structures and Electromagnetic disciplines. In this study, aerodynamic optimization of a radome for a given antenna size is carried out using a combination Genetic Algorithm (GA) and traditional optimisation methods to find the Utopia point for further investigation on Multidisciplinary Design Optimization (MDO) of radome. This is necessary to progress on optimisation with other disciplines like Structures and Electromagnetics (EM)

The impact of structure’s material and dimensions on its natural frequency are lacking in recent literature. The main aim of that paper is investigating material’ characteristics effect on structures natural frequency. Five different types of materials (steel, concrete,wood, plastic and aluminum) which mostly used in engineering applications implemented in this study. A fuzzy system designed and structured for each type of materials. It used to optimize the natural frequency values related to height and area of structure. The results show that whilst the height of the structure is a very influential factor on its natural frequency, the type of material as well as area of the structure are also effective variables. For the same dimensions of the structure, wood shows the highest value of natural frequency, then steel followed by concrete. In addition, the natural frequencies of structures have been assessed against the wind, earthquakes and traffic vibrations. These results can have useful applications and recommendations for engineering and design purposes. Wood can complement natural properties of a range of materials. Implications from this investigation can be useful for heavy machines laboratories, building structures and other engineering applications.

Single Shot Multibox Detector is a feed forward convolution network that is combined with MobileNets to give efficient and accurate results. MobileNets combined with SSD and Multibox Technique makes it much faster than SSD alone can work. The accuracy for this technique is calculated over colored (RGB images) and also on infrared images and its results are compared with the results of shallow machine learning based feature extraction plus classification technique viz. HOG plus SVM technique. The comparison of performance between proposed deep learning and shallow learning techniques has been conducted over benchmark dataset and validation testing over own dataset in order measure efficiency of both algorithms and find an effective algorithm that can work with speed and accurately to be applied for object detection in real world pedestrian detection application.

Nowadays, internet has become the easiest way to obtain more information from the web and millions of users search internet to find out the information. The continuous growth of web pages and users interest to search more information about various topics increases the complexity of recommendation. The user's behavior is extracted by using the web mining techniques, which are used in web server log. The main aim of this research study is to identify the navigation pattern of users from the log files. There are three major steps in the web mining process namely pre-processing the data, classification of pattern and users discovery. In recent periods, the web page articles are classified by the researchers before recommending the requested page to users. However, every category size is too large or manual labors are often needed for classification tasks. A high time complexity issues are faced by some existing clustering methods or according to the initial parameters, these techniques provides the iterative computing that leads to insufficient results. To address the above issues, a recommendation for web page is developed by initializing the margin parameters of classification techniques which considers both effectiveness and efficiency. This research work initializes the Random Forest's (RF) margin parameters by using the FireFly Algorithm (FFA) for reducing the processing time to speed up the process. A large volume of user's interest data is processed by these margin parameters, which provides a better recommendation than existing techniques. The experimental results show that RF-FFA method achieved 41.89% accuracy and recall values, when compared with other heuristic algorithms.

In this paper is presented a novel area efficient Fast Fourier transform (FFT) for real-time compressive sensing (CS) reconstruction. Among various methodologies used for CS reconstruction algorithms, Greedy-based orthogonal matching pursuit (OMP) approach provides better solution in terms of accurate implementation with complex computations overhead. Several computationally intensive arithmetic operations like complex matrix multiplication are required to formulate correlative vectors making this algorithm highly complex and power consuming hardware implementation. Computational complexity becomes very important especially in complex FFT models to meet different operational standards and system requirements. In general, for real time applications, FFT transforms are required for high speed computations as well as with least possible complexity overhead in order to support wide range of applications. This paper presents an hardware efficient FFT computation technique with twiddle factor normalization for correlation optimization in orthogonal matching pursuit (OMP). Experimental results are provided to validate the performance metrics of the proposed normalization techniques against complexity and energy related issues. The proposed method is verified by FPGA synthesizer, and validated with appropriate currently available comparative analyzes.

This article shows the changes in fiber waste from cotton processing and how it is gradual. The dust emitted in the dry-cleaning shop is only 5-7 mg/m3 of dust, less than the air in the building where the drying machines are located. This is due to the fact that high moisture is absorbed into the dryers, which prevents the separation of fine dust from the mass. The large dispersed dust, even at high humidity, was separated and was unable to disperse in the building. In the drying units, dust that comes with an atmospheric drying agent causes trouble. This dust, even with a rough dispersion, sits in the dryer along with the gas flow to the roof of the building and the ground near the drying shop. The amount of dust released is 500-600 kg/day. In the compartment, the dust emits from the air pneumatic system, which is an indispensable dust in the air drying shop, as well as the dust generated by cleaning machines. This is a powdery fiber, which contains less mineral fractions. The small fractions are composed of mostly dirty particles. Powdered air is also isolated from aspirate systems of gin suppliers, which absorb absorbed air or polluted air from pollutants. Such suction system can be included in the aspiration of the cotton distribution screw. It is established that only one cotton gin industry produces 150-350 tons of fiber per year, industry-wide waste is 5-6 tons, and 70-90% of organic waste is non-toxic. This will serve as a feedstock for the use of animal feed in the agricultural sector. Researches have been carried out to identify the amount of emissions from the ginneries at the Karasu, Mustaqillik and Ginnery factories in the Tashkent region and the Metan cotton gin enterprises in Samarkand region.
