Entrepreneurship education and development as an integral part of the enterprise system in Saudi Arabia

The impact of entrepreneurial activity on the economies of both industrialised and developing countries has been well established and theorised in the normative literature. However, it is besides eminent that the development of entrepreneurial activities and behaviour, through facilitation of education institutions, is less understood. As an engine of economic growth, there is intense interest from policy makers and academicians towards entrepreneurship and entrepreneurship education. Many economists and politicians agree that entrepreneurship stimulates the generation of employment opportunities and wealth creation. As a result of these theorised conceptions, this paper takes a step forward and explores the role of Higher Education Institutions (HEIs) in entrepreneurship education and development in the context of Saudi Arabian economy. In doing so, the authors propose their conceptual framework that incorporates facets (based on entrepreneurship/experience and entrepreneurship education) of two theoretical frameworks. In summarising the conclusions, the authors present their research approach employed for validating their conceptual research framework

KAJIAN PENGARUH JENIS MATERIAL TERHADAP KUALITAS UKURAN PADA PROSES PENEKUKAN PELAT DENGAN METODA ANOVA

Abstract In previous research, it has been proven that the measurement technique, setting and use of quality measuring instruments can increase the quality of measurements during the bending process of steel plates (ST.37). However, this research has not examined the types of materials other than steel, even though other materials apart from ST.37, for example aluminum plates, brass plates and steel plates are widely used, especially in the manufacturing industry.. Therefore, the aim of this research is to analyze the effect of the type of material on the quality of the measurement in the bending process. This study uses an experimental method, combined with a theory that supports the discussion of the problem. The materials used are 3 different types of material plates (aluminum plate, brass plate and steel plate). The parameters observed include the measurement technique, setting and use of measuring instruments. Each material received 10 repetitions of the measurements. These three parameters were analyzed using ANOVA statistics, in order to determine the quality of the measurement of each material and the most dominant factors affecting the quality of the measurements. Keywords: Plates, measurements, bending processes, and statistics.Abstrak Pada penelitian sebelumnya telah dibuktikan bahwa teknik pengukuran, setting dan penggunaan alat ukur yang berkualitas dapat meningkatkan kualitas pengukuran pada saat proses pembengkokan pelat baja (ST.37).

Enhancement Of Medical Image Compression Algorithm In Noisy WLANS Transmission

Advances in telemedicine technology enable rapid medical diagnoses with visualization and quantitative assessment by medical practitioners.In healthcare and hospital networks,medical data exchange-based wireless local area network (WLAN) transceivers remain challenging because of their growing data size,real-time contact with compressed images,and range of bandwidths requiring transmission support.Prior to transmission,medical data are compressed to minimize transmission bandwidth and save transmitting power.Researchers address many challenges in improving performance of compression approaches.Such challenges include energy compaction, computational complexity,high entropy value,drive low compression ratio (CR) and high computational complexity in real-time implementation.Thus,a new approach called Enhanced Independent Component Analysis (EICA) for medical image compression has been developed to boost compression techniques;which transform the image data by block-based Independent Component Analysis (ICA).The proposed method uses Fast Independent Component Analysis (FastICA) algorithm followed by developed quantization architecture based zero quantized coefficients percentage (ZQCP) prediction model using artificial neural network. For image reconstruction,decoding steps based the developed quantization architecture are examined.The EICA is particularly useful where the size of the transmitted data needs to be reduced to minimize the image transmission time.For data compression with suitable and effective performance,enhanced independent components analysis (EICA) is proposed as an algorithm for compression and decompression of medical data.A comparative analysis is performed based on existing data compression techniques:discrete cosine transform (DCT), set partitioning in hierarchical trees (SPIHT),and Joint Photographic Experts Group (JPEG 2000).Three main modules,namely,compression segment (CS),transceiver segment (TRS),and outcome segment (OTS) modules,are developed to realize a fully computerized simulation tool for medical data compression with suitable and effective performance.To compress medical data using algorithms,CS module involves four different approaches which are DCT, SPIHT,JPEG 2000 and EICA.TRS module is processed by low-cost WLANs with low-bandwidth transmission.Finally,OTS is used for data decompression and visualization result.In terms of compression module,results show the benefits of applying EICA in medical data compression and transmission.While for system design,the developed system displays favorable outcomes in compressing and transmitting medical data.In conclusion,all three modules (CS,TRS,and OTS) are integrated to yield a computerized prototype named as Medical Data Simulation System(Medata-SIM) computerized system that includes medical data compression and transceiver for visualization to aid medical practitioners in carrying out rapid diagnoses

Change Management in the Implementation of LearningCare in Universiti Utara Malaysia

Most educational institutions' administrators are concerned about e-learning and distance learning. University Utara Malaysia (UUM) Group Web communication application is a module of e-learning. Toward this end, University Teaching and Learning Centre (UTLC) has been made responsible in implementing e-learning in the university. The E-university committee has agreed to purchase Learningcare Learning Management System (LMS) for academic purposes. This system became operational in May 2002/2003 Semester. The value of e-learning has become widely recognized and accepted. This study aims to find out whether change management principles were used in the implementation of Learningcare. The study focuses on the adoption of Learningcare in University Utara Malaysia and the role of various players in UUM responsible for the development and implementation of Learningcare. John Kotter, eight stages of change management principles were chosen as the study change management platform. Correlation analysis was applied to test the eight dimensions of Kotter's change management principles. The results indicate that change management was applied in the implementation of Learningcare in UUM

Modelling of Libyan crude oil using artificial neural networks

The preparation and analysis of input and model data was carried out. The importance of the correct technique of data filtering was highlighted with particular focus being emphasised on the removal of outliers in raw data. An important process in the use of Artificial Neural Network (ANN) models was identified as being the selection of the right input variables.A comparison between using factor analysis and statistical analysis in the selection of inputs and it was observed that the former gave significantly better results. The training and testing phase of Artificial Neural Network (ANN) model development was shown to be an important step in Artificial Neural Network (ANN) model development. If this phase was wrongly done then the ANN model would not be accurate in its predictions. Optimisation of the ANN model architecture was carried out with the amount of hidden layers, amount of neurons in the hidden layers, the transfer function used and the learning rate identified as key elements in obtaining an Artificial Neural Network (ANN) architecture that gave fast and accurate predictions. Fresh water addition and demulsifier addition were identified as key parameters in the economic performance of the desalting process. Due to a scarcity of water and the high cost of the demulsifier chemical it was important to try and optimise these two input variables thus reducing the cost of operations

DNA-templated poly(N-substituted pyrrole)bipyridinium nanowires

PhD ThesisConductive polymers nanowires have been prepared using DNA-templating methods from monomer units designed in modular form. The monomer units comprise a polymerisable, pyrrolyl group, and a flexible alkyl linker attached to bipyridine groups in order to provide a metal-binding functionality within the polymers. The possibility for these DNA/polymer nanowires to act as templates for deposition of metal with enhanced electrical conductivity was also explored. Pyrrole with a flexible alkyl linker was combined with; pyridine (mono-I) as a control experiment, 2,2` bipyridyl (mono-II) and 4,4` bipyridyl (mono-III) with a metal ion binding site (nitrogen atom). This was in order to provide the metal-binding functionality for metal deposition to improve the conductivity as well as the morphology of the aimed hybrid templated nanowires. This series of pyrrole-pyridine derivatives were characterised using a range of techniques such as Proton Nuclear Magnetic Resonance (1H NMR) spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy, Mass Spectroscopy (MS) and Elemental Analysis. Prior to the nanowires fabrication, pyrrole, as a control, and the prepared monomer units (mono-I, mono-II and mono-III) were chemically polymerised in a bulk scale using FeCl3 as an oxidant, then spectroscopic data and electrical conductivity of the resulting polymers were measured. A significant decrease in conductivity of poly-I, poly-II and poly-III compared to PPy, but was especially observed for the bipyridinium derivatives. This was suggested to be due to the steric hindrance of the alkyl side chain in the polymer backbone, in addition, the involvement of the non-quaternised pyridyl nitrogen in poly-II and poly-III by the nucleophilic attack on pyrrolyl groups in the polymerisation reaction. DNA-templated poly(N-substituted pyrrole)bipyridinium nanowires were synthesised at room temperature using the chemical oxidation method. The resulting CPs/DNA hybrids have been characterised using electronic and vibrational spectroscopic methods especially Ultraviolet-Visible (UV-Vis) spectroscopy and FTIR spectroscpy. The nanowires morphology was characterised using Atomic Force Microscopy (AFM). The electrical properties of the prepared nanowires were characterised using Electrostatic Force Microscopy (EFM), and measured using conductive AFM (c-AFM) and two iii terminal I/V technique, where the temperature dependence of the conductivity was probed. The conductivities of the prepared CPs/DNA nanowires are generally lower than PPy/DNA nanowires showing the large effect on N-alkylation in decreasing the conductivity of the polymer, but these are higher than the conductivity of their corresponding bulk films. This enhancement in conductivity could be attributed to the ordering of the polymer chains on DNA during the templating process. Finally, the prepared CPs/DNA nanowires were used as templates for the growth of copper nanowires at room temperature using aqueous solution of Cu(NO3)2 as a source of Cu2+ and ascorbic acid as reducing agent. AFM images showed that these nanowires were uniform and continuous compared to copper nanowires prepared using the templating method directly onto DNA. Electrical characterization of the nanowires by c-AFM revealed slight improvement in conductivity of these nanowires (Cu-CPs/DNA) compared to CPs/DNA nanowires before metallisation. Using similar preparation method, Poly-II/DNA nanostructures were also used as templates to direct the formation of Pd nanowires. An aqueous solution of PdCl2 was used as a source of Pd2+ ions and NaBH4 solution was used as reducing agent. AFM studies show that the resulting Pd-poly-II/DNA nanowires exhibit continuous and smooth morphology. Electrostatic Force Microscopy showed that these nanowires are electrically conductive.Libyan governmen
