In this research, we propose a particular version of KNN (K Nearest Neighbor) where the similarity between feature vectors is computed considering the similarity among attributes or features as well as one among values. The task of text summarization is viewed into the binary classification task where each paragraph or sentence is classified into the essence or non-essence, and in previous works,...
This paper introduce design, implementation and measurement of front end crystal video receiver (CVR) that operates in the frequency range of 8–10 GHZ to intercept short duration pulse radar signals. The proposed receiver is designed with two outputs, video signal for real-time signal processing and an amplified version of the received signal for frequency measuring and/or determine the presence of...
In this research, we propose the version of K Nearest Neighbor which considers similarity among attributes for computing the similarity between feature vectors. The text segmentation task is viewed into the binary classification where each pair of sentences or paragraphs is classified into whether we put the boundary or not, and the proposed version resulted in the successful results in previous works...
This paper concerns with the design and implementation of a microcontroller based PID controller for the purpose of controlling PMDC motor speed. The design had been done using MATLAB and Simulink and the system then simulated using Proteus, in addition to a practical physical system. The controller was implemented on an Arduino Uno board to control the speed of the motor at a desired value with the...
In antenna arrays, the excitation amplitude of the individual elements is one of the major controls that can be used to shape the overall pattern of the antenna. In this paper, 1×10 rectangular patch antenna array is designed and simulated at 9.5 GHZ on specific microwave laminate using uniform, Dolph-Tchebyscheff and Binomial amplitude distributions for specific spacing between elements. The particular...
One of the essential divisions of the fast developing field of vehicular technology is the vehicle to infrastructure (V2I) communications. The PHY layer of V2I is implemented by the IEEE 802.11p wireless standard, whose core is the Orthogonal Frequency Division Multiplexing (OFDM) due to its robustness against multipath fading. The recently developed technique called OFDM with Index Modulation (-IM)...
High penetration of distributed generation leads to the importance of adapting the new trend of Smart Grid to divide the grid into intelligent Micro-Grid zones and facilitate its operation using decentralized distributed control schema. In this paper a practical Microgrid model has been designed and simulated using MATLAB/SIMULINK (MATrix LABoratory). JADE (Java Agent DEvelopment Framework) platform...
This electronic document is about to calculate the performance of cloud computing for distributed data center using cloud-sim software programme, The simulation and performance analysis will be done by using the cloud analyst tool. It is easy to evaluate new strategies in utilization of clouds considering policies, scheduling algorithms, load balancing policies, etc. It can also be used to assess...
Digital audio compression is applied to reduce the data rate required to send audio stream through band limited communication networks, as well as reducing the size of data storage in case of recording audio streams. It is common to apply lossy audio compression algorithms in many applications, which provide higher compression at the expense of the fidelity. MPEG-1&2 Audio Layer III, or MP3, is...
Renewable energy resources such as Solar, wind and hydro are pollution free, easily erectable, and limitless so they represent reliable alternatives to conventional energy sources e.g. oil and natural gas. However, the efficiency and the performance of these systems are still under development. Among them, Photovoltaic systems are mostly used as they are light, clean and easily installable. This systems...
The excessive use of the communication networks, rising of Internet of Things leads to increases the vulnerability to the important and secret information. advance attacking techniques and number of attackers are increasing radically. Intrusion is one of the main threats to the internet. Hence security issues had been big problem, so that various techniques and approaches have been presented to address...
A new tracking controller for a wheeled mobile robot based on backstepping approach is presented. The proposed controller was developed based on the kinematic model of the nonholonomic wheeled mobile robot. The controller is verified through a well-established method Lyapunov function.
This paper proposed a hybrid energy system containing diesel generators, photovoltaic cells and wind turbines, along with storage devices, to supply a continuous load of an industrial facility. The main objective of the paper is to determine the optimal size of the hybrid scheme with the lowest Net Present Value (NPC), and the reliability indices for the proposed system. The overall optimized results...
Necessities of newer radar systems are becoming even more demanding in modern electronic warfare ECM (Electronic Countermeasures) scenarios; therefore, ECCM (Electronic counter-countermeasure) technology has become one of the essential functions of the radar system evaluation. This paper provides an outline of the current research status, developments, achievements of frequency diverse array (FDA)...
Wireless sensor network become the most important part in any technology that need to monitor the environment. One of the new trends that need wireless sensor network is military applications. Some of the previous studies used Bluetooth module to send the measured weather factors wirelessly from the weather factors monitoring system to the central station. The problem of using Bluetooth module is...
During the last decade a huge amount of data have been shown and introduced in the Internet. Recommender systems are thus predicting the rating that a user would give to an item. Collaborative filtering (CF) techniques are the most popular and widely used by recommender systems technique, which utilize similar neighbors to generate recommendations. This paper provides the concepts, methods, applications...
Content-based image retrieval (CBIR) is a technique uses visual contents such as color, texture and shape to search images from large scale image databases according to users' interest. In a CBIR, visual image content is represented in form of image features, which are extracted automatically and there is no manual intervention, thus eliminating the dependency on humans in the feature extraction stage...
Microwave links have to be designed such that propagation effects do not reduce the quality of the transmitted signals. Measurements and the derived propagation parameters are analysed and discussed. Metrological parameters data(Visibility, Temperature, Relative humidity and Atmospheric Pressure) gotten from the Sudan Meteorological Authority (SMA) are used to calculate the daily averages of refractivity...
The main goal of autonomic computing is to make the software systems able to manage themselves and minimize the human intervention. Various methods have been used to implement autonomic computing. This research focused on one of the autonomic computing characteristic which is self-optimization. The research tried to implement self-optimization system that helps to get result used to support reports...
