Abstract: Hydrodynamic behaviour of a fluid flow in micro-venturi is investigated numerically taking into account the effect of the Knudsen number (Kn), diameter ratio (b), and Reynolds number (Re). It is found that the velocity jump in the throat of the venturi increases with increasing Re. The axial velocity takes its maximum values at the narrowest section, and these values increase with decreasing Kn. Also, it is found that the dimensionless pressure distribution and the net pressure loss increase as Kn decreases while pressure attains its maximum values at the entrance section. On the other hand, it is observed that increasing Kn and decreasing b cause the discharge coefficient to decrease.

Keywords: micro-venturi, knudsen number, diameter ratio, velocity jump.

Abstract: The costs play important role in the growth of corporations’ especially industrial sector. In the low-income country like Jordan, the article aims to analyze the effect of adopting Activity Based Costing (ABC) on the financial performance of Jordanian industrial shareholding companies. The population of this study consists of (13) public shareholding industrial companies in Jordan out of (70) from the period of 2000-2014. Four years average before and after applying ABC system is taken for all variables and significance is tested with the help of paired sample t-test statistics. Dependent variable in this study is the implementing of ABC system, and independent variables are gross profit margin (GPM), margin before interest and tax ratio (MBIT), net profit margin ratio (ROS), return on assets (ROA), return on equity (ROE) and return on investment ratio (ROI) have been computed. The results show that 78 Performance variables shows that the direction for the improved ratios after implementing ABC system is 37 Performance variables (37/78, 47%), and remaining 41 (41/78, 53%) Performance variables direction shows deterioration in the after implementing ABC system period. Out of 37 improved ratios 4 Performance variables are statistically significant. In the other hand out of 41 deteriorated ratios 7 Performance variables are statistically significant.

Abstract: The study aims to identify the impact of Security and protection , legislation and laws on the quality of internal auditing in the financing companies operating in Jordan, which are (26) companies. A questionnaire was designed by the two researchers and distributed for this purpose on the internal auditors in companies and non-executive committees emanating from the Board of Directors who have direct contact with internal audit in each companies, the number of questionnaires distributed were (150) questionnaires, (120) suitable questionnaires were recovered for analysis, with the rate of recovery reached (80%). The questionnaire data was analyzed using the (SPSS) and a number of statistical techniques through descriptive statistics, arithmetic means, standard deviations and percentages, the study hypotheses were tested by multiple regression tests. The study found that there was no significant impact for the combined independent variables (Security and protection , legislation and laws) on the quality of internal auditing, but there is a statistically significant impact of Security and protection on the quality of its own internal auditing. The study recommends the interest of existing and decision-makers in the financing companies operating in Jordan to raise the level of legislation and laws in order to positively affect the quality of internal auditing in those companies.

Abstract: The study aimed at measuring the role of auditor governance and its effect on the gap credibility of accounting information; that was done from the point of view of auditors in licensed offices in Jordan. To achieve this goal, the researcher dealt with two kinds of data; those were the secondary and the primary ones. A questionnaire was distributed to the sample which included 261 auditors working at the offices included in the study. It was found that there was an effect for the governance mechanisms for the auditors (auditors' in dependency, auditors' commitment to auditing standards, auditors' commitment to the job behavior rules, and auditors' commitment to the quality control standards) on the accounting information credibility gap from the point of the auditors.

Abstract: The wide availability of services and devices within contemporary smart home environments makes their management a challenging and rewarding task. Maintaining complex smart home systems throughout their lifecycle entails considerable resources and effort. These challenges have stimulated the need for dynamic auto-configurable services amongst such distributed systems. This research aims to devise methods to automate the activities associated with customised service delivery for dynamic home environments by exploiting recent advances in the field of ubiquitous robotics and semantic web technologies. It introduces a novel approach called the knowledge-based auto-configuration ubiquitous robotics for smart home environments, which utilises the Sobot to achieve auto-configuration of the system. A proof-of-concept testbed has been designed, implemented and validated via several case studies. The results show that the Sobot is capable of creating and executing new or alternative feasible configurations to meet the system's goal by utilising inferred facts based on the smart home ontological model, so that the system can adapt to the changed environment.

Abstract: Long life of the equipments for oil extraction has big importance in the national economy. This equipment breaks down due to wear and tear. The method of detonation precipitation has an important place among different methods of thermal spraying which allow to get high density gas coating and high strength of tenacity with basic metal. For precipitate the coating we use standard powder of Al2O3 have grains size 20-36 µm and mechanical mixture of: Al2O3 +3% Cr2O3 and Al2O3 + 3% TiO2. Analyze of Tested samples , shows that on the active surface of detonation coating which consist of big single grains , which have low porosity , there is no cavitation breakdown in the first hour of experiment. Whereas explosion bubbles don’t cause cracks, extractions, and holes. With passing of time a micro deformations is appeared on the coating surface in the holes and micro curves and explosion bubbles places. And this micro deformations with continues of current flow, causes micro cracks, which increases and cause breakdown of coating between molecules and grains and extract grains from the coating and moved it away of cavitation area
