Cooperating Newton’s Method with Series Solution Method for Solving System of Linear Mixed Volterra-Fredholm Integral Equation of the Second Kind
No full textIn this paper, for the 1st time, we use Newton’s method with series solution method (SSM) for solving system of linear mixed Volterra-Fredholm integral equations of the second kind (SLMVFIE-2). In this work, we use a new technique for studying the numerical solutions for SLMVFIE-2 which is Newton’s method with SSM, first solving this system using SSM and after that cooperation Newton’s method with SSM, suggesting an algorithm for the technique. The new results are achieved and some new theorems have proved for convergence of the method, several numerical examples are tested for illustrating the usefulness of the technique; the numerical results are obtained and compared with the exact solution, computing the least square error, and running times which are criterion of discussion. For programming the technique, we use general Matlab program

Evaluation of Construction Delay of Public Projects in Erbil Governorate
No full textDelay is one of the greatest challenges facing the implementation of construction projects. The completion project time is considered one of the measure indicators for assessing the success of any project. Delays usually have negative impacts of financial and social to all parties involved in the projects. The aim of the study is to find the most important causes of delay by evaluating the common causes of delays in terms of frequency, severity, and important indices in implementation of public construction projects in Erbil Governorate related to owners, contractors, consultants, and external factors. The data gathered through conducting a questionnaire for perception various parties involved in implementation of public construction projects. For these purpose, 104 forms of questionnaire were distributed to various parts to identify the delay causes in accordance with their opinions. It was concluded that the most significant factors causing the delay in construction of public project in Erbil Governorate related to the owner were “variation orders by owner during the construction” which came in the first rank, while the cause of delay related to the consultant that came in the first rank was “unclear and inadequate details in drawings,” whereas the factor related to the contractor which came in the first rank was “selecting incompetent contractor.
Design and Implementation a Novel Research Management System
No full textPublications and researches are one of the important activities of higher education institutions (HEIs) worldwide. Many HEIs, especially in Iraq, are facing different types of problems in managing publication information. This paper presents the design and implementation of researches management system (RMS) to be adopted in one of the state universities in Iraq. RMS is a web-based application to manage the publications and researches information in HEIs. The main goals of this application are collecting all submission publication information in a central database, generating different types of publication reports, generating real-time different statistics, saving all researchers information in the HEI, and facilitating checking and tracking the submitted researches
Simulation-based Evaluation of Mobile Ad Hoc Network Routing Protocols: Ad hoc On-Demand Distance Vector, Fisheye State Routing, and Zone Routing Protocol
No full textMobile ad hoc network (MANET) is an infrastructure-less and decentralized network without any physical connections. Nodes are mobile, free to move, and independent of each other which makes routing a difficult task. Hence, a dynamic routing protocol is needed to make MANET reliable and function properly. Several routing protocols have been proposed with different working mechanisms and performance levels. Therefore, the performance study of those protocols is needed. This paper evaluates the performance of MANET routing protocols using simulation based experiments to observe the behavior of the network as the density of the nodes increases. The paper evaluates the performance of proactive (fisheye state routing), reactive (ad hoc on-demand distance vector), and hybrid (zone routing protocol) routing protocols in terms of the packet delivery fraction, average throughput, and average end-to-end delay. The simulations of protocols to analyze their performance in different conditions were performed using the network simulator 2 (NS 2)
Automatic Identification of Communication Signals Using Zero-Crossing Based Techniques
No full textThe identification of different types of modulation for any intercepted communication signal out of the vast hierarchy of possible modulation types is a key fundamental before advising a suitable type of demodulator, where this process is usually a manual option. This technique is extremely important for the purposes of communication intelligence. In this paper, a proposed methodology is suggested, validated, and tested (through computer simulations) for the automatic identification of the modulation type (analog and digital) of the intercepted communication signals. The methodology is based on the zero-based representation of signals and utilization of new algorithms for such identification
A Study on the Perceptual Relationship between Overtime and Output: Case Study of Knowledge University
No full textThe overtime is an extra effort to ensure that the job or duty is completed. In private universities, overtime is needed to cover all hours of the courses and this may affect in a good or bad way on the lecture "depending on the number of extra hours". This research highlights the importance of overtime and how it affects the performance of private universities. The (SPSS) program has been used to analyze the data. 34 questionnaire papers were obtained out of 40 have been distributed on employees at Knowledge University. The study found that there is a strong relationship between employees' Productivity and factors (Wages, Environment and Health, Job content and IT skill). Moreover, there is a weak relationship between Employees' Productivity and factors (Work Arrangement, Stress–Satisfaction)

The topic of (The impact of Internet on social relationships among university students in the Kurdistan Region), though it has been analyzed in few researches which is not enough for this topic. At the same time, the main objective of this research refers to the analyzing process of an essential topic, which is linked to the social findings of the effects of the Internet as discussing the effect of the Internet on social relationships between university students in the Kurdistan Region). Nowadays, generally the Internet has many effects and various different influences on social relations in the Kurdistan Region, in which Kurdish researchers have carried out less research on this sensitive topic.Since, media is counted as an important pillar in life aspects and community. Also, electronic media (the Internet) is the most influential and modern brand of media. Besides, with the rapid development of science, technology and devices, the important of media has increased. Therefore, this research has its importance and attention for the Kurdistan Region. At the moment the Internet has serious effects on, social, political, and economic aspects of a country, among the effects, which has created on social lif
