The research aims to show the relationship between the use of automated accounting systems technology and its impact on enhancing the efficiency and effectiveness of the internal control system in a sample of Bahraini universities in light of the rapid changes in the electronic business environment. Automated accounting and its impact on enhancing the efficiency and effectiveness of the internal control system, and it is concluded through the analytical study of the research sample that there is a percentage (93%) of the total respondents agree and fully agree that the use of automated accounting systems in Bahraini universities contributes significantly to enhancing the efficiency of the internal control system and its effectiveness, and the research recommends that it is necessary to use automated accounting systems of all kinds in the field of accounting information systems, because their use will increase the efficiency and effectiveness of these systems and thus will add value and a competitive advantage to the accounting units in Bahraini universities and will have a clear and direct positive impact on the future of those units and individuals working in them . It also recommends the need to raise the scientific and practical qualification of accountants working in universities. The future accountant should have technical knowledge of using automated accounting systems and be familiar with how to use them in order to employ this knowledge when the accounting units choose and determine the types of information and communication technologies to be used that are commensurate with the nature of work those units. It also recommends that the accounting units should develop accounting information systems by introducing the latest automated accounting programs and training accountants on them, whether these programs were designed specifically for the unit or they are ready-made programs and modifications were made to them in proportion to the nature of the unit’s work, without neglecting the interest in the communication network, because the production of The accounting unit of information without delivering it to the beneficiary parties will negatively affect the entire accounting unit, and make it isolated from its environment. Also, when designing a new automated accounting information system for the accounting unit or making an amendment or development of the existing system in it, the accountant should be a member of the design team This is because the responsibility for designing the concepts lies with him, in addition to the need for the accountant to be a member of the analysis team that takes place before starting the design process, because he is one of the most knowledgeable individuals in the details of work within the unit.

Visible Light Communication (VLC) has emerged as a powerful technique for wireless communication systems. Providing high data rate and increasing capacity are the major problems in VLC. Recent evidence suggests that Multiple Input Multiple Output (MIMO) technique can offers improved data rates and increased link range. This paper describes the design and implementation of visible light communication system in indoor environment exploring the benefits of MIMO. The specific objective of this research was to implement a 4× 4 Multiple Input (LEDs) Multiple Output (photodetectors)-VLC communication system, where a 16 white power LEDs in four arrays are setting up at transmitter and four RX modules are setting up at receiver side without the nee

In data transmission a change in single bit in the received data may lead to miss understanding or a disaster. Each bit in the sent information has high priority especially with information such as the address of the receiver. The importance of error detection with each single change is a key issue in data transmission field.
The ordinary single parity detection method can detect odd number of errors efficiently, but fails with even number of errors. Other detection methods such as two-dimensional and checksum showed better results and failed to cope with the increasing number of errors.
Two novel methods were suggested to detect the binary bit change errors when transmitting data in a noisy media.Those methods were: 2D-Checksum me
Anomaly detection is still a difficult task. To address this problem, we propose to strengthen DBSCAN algorithm for the data by converting all data to the graph concept frame (CFG). As is well known that the work DBSCAN method used to compile the data set belong to the same species in a while it will be considered in the external behavior of the cluster as a noise or anomalies. It can detect anomalies by DBSCAN algorithm can detect abnormal points that are far from certain set threshold (extremism). However, the abnormalities are not those cases, abnormal and unusual or far from a specific group, There is a type of data that is do not happen repeatedly, but are considered abnormal for the group of known. The analysis showed DBSCAN using the

Many purposes require communicating audio files between the users using different applications of social media. The security level of these applications is limited; at the same time many audio files are secured and must be accessed by authorized persons only, while, most present works attempt to hide single audio file in certain cover media. In this paper, a new approach of hiding three audio signals with unequal sizes in single color digital image has been proposed using the frequencies transform of this image. In the proposed approach, the Fast Fourier Transform was adopted where each audio signal is embedded in specific region with high frequencies in the frequency spectrum of the cover image to sa

Background: Good Nutrition is essential for oral and dental health in children. Good eating habits and food preferences are established early in childhood. Oral health problems can effect dietary quality and nutrient intake in another side increase the risk of several systemic diseases., The aim of the present study was to investigate the relation or the effect the of nutritional status in children at age of 5 to16 on the oral health status and dental caries . Materials and Methods: the total sample composed of 153 patients attending the Pedodontic and Preventive Department/College of Dentistry/University of Baghdad, the assessment of nutritional status was performed by using Body Mass Index specific for age and gender according to Chronic
