Indian Number Handwriting Features Extraction and Classification using Multi-Class SVM

H.A. Jeiad

Engineering and Technology Journal, 2018, Volume 36, Issue 1A, Pages 33-40

In this paper, an Indian Number Handwriting Recognition Model (INHRM) is proposed. Mainly, the proposed model consists of four phases which are the image acquisition, image preprocessing, features extraction, and classification model. Initially, the captured images of the handwritten Indian numbers were enhanced and preprocessed to obtain the skeleton for the interested object. The extracted features of the handwritten Indian numbers were obtained by calculating four parameters for each captured number sample, these parameters are the number of starting points, the number of intersection points, the average zoning which consists of four values, and finally, the normalized chain vector of length of 10 elements. So, the resulted 16 values of the four parameters were arranged in a vectors of length of 16 elements. These features vectors were used in the training and testing processes of the proposed INHRM model. Multi-class SVM (MSVM) approach is suggested for the classification phase. An accumulation of 600 samples of various handwritten Indian numbers styles has been gathered from a group of 60 students. These samples were preprocessed, features extracted, then delivered to the classification phase by utilizing 500 samples of them for training while the remaining 100 samples were used for testing of the MSVM-classifier model. The results showed that the proposed INHRM achieved relatively high percentage of exactness of around 97%.

Biometric systems refer to the systems used for human recognition based on their characteristics. These systems are widely used in security institutions and access control. In this work three biometric sources were used for identification purposes. Singular value decomposition (SVD) was employed as a tool for feature extraction and artificial neural network (ANN) was used as pattern recognition for the model. High accuracy was obtained from this work with 95% recognition rate.

Engineering and Technology Journal, 2015, Volume 33, Issue 4, Pages 960-972

Surface modeling utilizing B-spline technique is one of the most important tool in computer aided geometric design (CAGD). The aim of this paper is to build and develop an algorithm to design and implement the multi-patches of B-spline free-form surfaces. The technique has an effective contribution in technology domains and in aircrafts, ships, and cars industry, moreover for its wide utilization in making the molds. Blending the patches together in order to build the entire surface have been implemented to represent the different types of B-spline surfaces. This work includes the synthesis of these patches in a way that allows the participation of these control points for the merged patches, and the confluence of these patches at similar weights sides due to weights variation per patch.

Cloud computing system provides large-scale infrastructure for high performance computing. The convergence of interests between multi-agent systems that need reliable infrastructures and cloud computing systems that need intelligent software with dynamic, flexible and autonomous behavior can result in new systems and applications.
This paper presents a proposed system using the intelligent multi-agent system in cloud computing .When it comes to developing the way of thought in a given environment, it is essential to think on a critical level in order to reach a state of understanding and operating on a level that best suits the needs of the said environment through evaluating the status of a situation and working to reach a decision or take an action.
The work presented aims to reach this state of smart decision-making that is essential to software developers when they are laying the foundations of the software internalization. The proposed system pioneers led the use of a multi-agent system in cloud computing, as there was no such initiative before in the development of software. The system proposed introduces a means for the autonomous decision-taking and critical thinking that is necessary to develop and evaluate the social behavior, universality and adaptive roles that the XML rational agent which is responsible for the cloud reservoir is capable of.

Suboptimal Resource Allocation for MIMO-FDMA Systems

Engineering and Technology Journal, 2014, Volume 32, Issue 2, Pages 481-493

In this paper, a pragmatic resource allocation algorithm for single-cell downlink multi input-multi-output (MIMO) based orthogonal frequency division multiple access(OFDMA) systems is proposed. The objective of this method is to maximize the average system throughput as a function of bit error rate and (BER) spectral efficiency by allocating the users, transmission power and information bits across the utilized subchannels. The resulting throughput maximization problem has been decoupled into two sub-problems to reduce the computational complexity, however, at the expense of performance a sub-optimal solution is obtained. The simulation results of the throughput and outage probability, obtained using MATLAB simulator, show the efficiency and accuracy of the proposed system in comparison with the other approaches.

Engineering and Technology Journal, 2013, Volume 31, Issue 19, Pages 146-158

This study implies a characterization and comparison between the historical limestone and gypsum stones of Al-Namrud or (Calah) monument which located in the north of Iraq 37 km to the eastern south of Mosul city (eastern bank of the Tigris river) and those (fresh) extracted from Al-Mur hill which suppose to be its quarry (according to the historicity and archeology references). The aim of this study is the conviction of the veracity of these references depending on a number of complementary engineering techniques. These tests include physicochemical and mineralogical properties of fresh and historical stones , textural arrangement of particles (porosity and pore size distribution) by mercury porosimetry tests; water transfer properties by water retention curve test; bulk density at dry state by hydrostatic weighing method have been executed . Also a comparison between the fresh and historical stones has been carried out by X-Ray Diffraction (XRD) and Thermo Gravimetric Analysis (TGA). Results shows for the historical stone higher porosity and different pore size distribution, water transfer properties in comparison to the fresh stone .Also, a high match in the compositions of stone materials of both historical and fresh one reflect the rightness of the historicity and archeology references and their consideration of being Al-Mur hill the quarry of Al-Namrud monument.

Jafar M. Hassan; Ali H. Tarrad; Mohammed N. Abdullah

Engineering and Technology Journal, 2009, Volume 27, Issue 13, Pages 2319-2338

In this investigation the individual component models for a typical subcritical cycle are developed based on the best published theoretical and empirical literature. The developed approach, especially for air conditioning systems, is conceptually new and can be used with modification to a variety of multicomponent system applications. The component models are then integrated and the model predictions validated against the data from various experimental test systems.
A variable speed compressor test rig was used to obtain the experimental data to be compared with the results predicted from the system model. The experimental data was monitored from the start-up of the system until the achievement of its steady-state. The system approached its steady-state after 270 sec and 360 sec for compressor speeds of 900 rpm and 1200 rpm respectively. The system disturbance was imposed by changing the operation conditions for each component. A comparison between the experimental data for these disturbances and theoretical results shows a good agreement with a discrepancy of
about (5%). The model can be used as a basis for the design, performance and efficiency of a vapor compression systems.
