Valuation the Impact of Risks on the Goals and the Safety of Construction Projects in Iraq
...Show More Authors

Construction projects have a special nature and affect them many factors making them exposed to multiple risks as a result of the length of the implementation period and the multiplicity of stages, starting from the decision stage through implementation until the final delivery, which leads to increased uncertainty and the likelihood of risk.
The process of analysis and risk management is one of the effective and productive methods that are used in managing the construction projects for the purpose of increasing the chances of ending the project successfully in terms of cost, time and quality and at the lowest possible problems.

The research aims first to the effective planning for analysis and risk management with different levels of importance according to specific strategy and effective based on experts in the field of risk management and, second, reaching measures to respond to the risks in order to ensure the management of these risks in construction projects. In this research a number of risks are identified which  that have been incurred actually after studying  a number of completed construction projects and theoretical studies and interview a number of experts in the construction industry to determine the impact of these risks in each of the project's objectives and safety.

It appeared that the most important risks in construction projects in Iraq  is ( the lack of drawings for networks service through the site such as electrical drawings, phone, water, etc.) and ( differences between the implementation and the required specifications because of a misunderstanding of the plans and specifications, It also appeared that the biggest effect of the risks is the on the duration of the project  and the least was on occupational safety, and the best  response  to the risk is to fix certain  conditions in the contract followed by other responses.

Multi-level control of zero-moment point-based humanoid biped robots: a review
...Show More Authors
SUMMARY<p>Researchers dream of developing autonomous humanoid robots which behave/walk like a human being. Biped robots, although complex, have the greatest potential for use in human-centred environments such as the home or office. Studying biped robots is also important for understanding human locomotion and improving control strategies for prosthetic and orthotic limbs. Control systems of humans walking in cluttered environments are complex, however, and may involve multiple local controllers and commands from the cerebellum. Although biped robots have been of interest over the last four decades, no unified stability/balance criterion adopted for stabilization of miscellaneous walking/running modes of biped </p> ...

Calculations of Signal to Noise Ratio (SNR) for Free Space Optical Communication Systems
...Show More Authors

In this paper, we calculate and measure the SNR theoretically and experimental for digital full duplex optical communication systems for different ranges in free space, the system consists of transmitter and receiver in each side. The semiconductor laser (pointer) was used as a carrier wave in free space with the specification is 5mW power and 650nm wavelength. The type of optical detector was used a PIN with area 1mm2 and responsively 0.4A/W for this wavelength. The results show a high quality optical communication system for different range from (300-1300)m with different bit rat (60-140)kbit/sec is achieved with best values of the signal to noise ratio (SNR).

Extraction of cobalt(II) from aqueous solution by N,N′-carbonyl difatty amides
...Show More Authors

The development of economic and environmentally friendly extractants to recover cobalt metal is required due to the increasing demand for this metal. In this study, solvent extraction of Co(II) from aqueous solution using a mixture of N,N0-carbonyl difatty amides (CDFAs) synthesised from palm oil as the extractant was carried out. The effects of various parameters such as acid, contact time, extractant concentration, metal ion concentration and stripping agent and the separation of Co(II) from other metal ions such as Fe(II), Ni(II), Zn(III) and Cd(II) were investigated. It was found that the extraction of Co(II) into the organic phase involved the formation of 1:1 complexes. Co(II) was successfully separated from commonly associated metal

Strengthening of Continuous Reinforced Concrete Deep Beams with Large Openings Using CFRP Strips
...Show More Authors

To accommodate utilities in buildings, different sizes of openings are provided in the web of reinforced concrete deep beams, which cause reductions in the beam strength and stiffness. This paper aims to investigate experimentally and numerically the effectiveness of using carbon fiber reinforced polymer (CFRP) strips, as a strengthening technique, to externally strengthen reinforced concrete continuous deep beams (RCCDBs) with large openings. The experimental work included testing three RCCDBs under five-point bending. A reference specimen was prepared without openings to explore the reductions in strength and stiffness after providing large openings. Openings were created symmetrically at the center of spans of the other specimens
