A NOVEL AND RELIABLE ATTRIBUTE RATIO CONGESTION CONTROL TECHNIQUE FOR WSN (ARCC)[Full-Text ] Dr. D.USHA,M.C.A.,M.Phil.,M.Tech.,Ph.DEffectiveness of a Wireless Sensor Network (WSN) is determined by its performance and any WSN can lose packets when it is congested. Sinks collecting information from other nodes are most likely to be less efficient when there is congestion. There are many congestion control algorithms while congestion detection and control are major research areas. There are various congestion control techniques in WSN’s based on many factors but controlling congestion becomes mandatory in WSN’s for better performance. The main contribution of this paper is a congestion control mechanism for reliability and management in a WSN.

Low Signature Advanced Base Bleed Grains[Full-Text ] Ehab. M. Youssef, Mostafa. A. Radwan, Hosam E. Mostafa, Moustafa. K. HadhoudBase bleed still one of the effective methods to extend the projectile range as it decreases the base drag which composes about 50% of the total drags acting on the projectile. Also, low signature propellants are very important in order not to reveal the gun position. So, various compositions are prepared to optimize the superior mechanical properties the propellant must achieve together with low signature. rocket propellants containing two bonding agents were studied Tris-1- (2-Methyl Aziridinyl) Phosphine Oxide (MAPO) and mixed MAT4 (which is a mixture of MAPO, adipic acid and tartaric acid) give us stress 11.7 Kg/cm2 and strain of 16.3 %, then curing ratio starting from 0.97 to 0.7 are also studied giving the optimum mechanical properties at 0.83 where the strain reached about 34%. Primary smoke is not affected by adding 7% of hexogen (RDX) instead of ammonium perchlorate (AP) but the secondary smoke is decreased by about 40%, while by adding 5% magnesium (Mg) secondary smoke is decreases by about 75% but the primary smoke is dramatically increased.

Seismic Behavior of High-Strength Reinforced Concrete Building Frames and Dual Systems Considering Soil Structure Interaction[Full-Text ] Ahmed Yousef, Salah Elmetwally, Mahmoud ElshahawyThis paper investigates the seismic behavior of moment resisting building frames and dual systems constructed from Normal-Strength Concrete (NSC with fc' = 25 MPa) and High-Strength Concrete (HSC with fc' = 75 MPa) considering Soil Structure Interaction (SSI) using Wolf model, Gazetas model, the method used by the International Building Code (IBC-2012) and the method used by the Egyptian code for soil mechanics and foundation design (ECP 202-2007). The study also includes the effect of soil type and the level of foundation. El Centro earthquake record has been selected as the input ground motion. The selected structures had been analyzed with aid of the computer program OPNSEES and material nonlinearity had been accounted for. The HSC models were designed with allowance for two options; keeping the dimensions of the cross sections constant or reduced along the height. The results showed that the calculated seismic response of multi-story reinforced concrete building frames and dual systems considering SSI is sensitive to the variation in the concrete strength. Considering the SSI using Wolf model for the case of soft soil with 12-story building frame resulted in an increase in the roof displacement relative to the fixed base by 18.0%, 16.0% and 15.0% for NSC, HSC with reduced sections and HSC with constant sections, respectively, while for Gazetas model these ratios are 20.0%, 21.0% and 12.0%, respectively, and for the IBC-2012 model these ratios are 13.0%, 15.0%, and 9.0%, respectively. For 12-story dual systems, considering the SSI according to Wolf model with soft soil resulted in an increase in the roof displacement relative to the case of fixed base by 40%, 38%, and 9% for NSC and HSC (reduced sections) and HSC (constant sections), respectively, while for Gazetas model these ratios are 63%, 61.0% and 14%, respectively, and for the IBC-2012 model these ratios are 42%, 30.0%, and 23.0%, respectively. The calculated maximum story drift considering the SSI with soft soil S1 for 12-story building frame constructed from HSC with fc' = 75 MPa exceeds the story drift limit required by the international codes by 7%, 13% and 67% for Wolf, Gazetas and ECP model, respectively. For the 12-story dual system the calculated maximum story drift is still within the limit of the international codes due to the large stiffness of the shear walls.

Improving Biogas Production from Sewage Water by Using Enzymes[Full-Text ] Emad Ahmad Yas, Moharram Fouad, Ahmed SultanBiogas production rate from sewage water has been increased more than 80% by adding digestive enzymes to simulated and natural sewage water under different operational conditions. These enzymes have included pepsin, Ox bile extract, single and mixed with concentration of (0.25, 0.5, 1, 2, 4) mg/l and (20, 30, 40, 50, 60) mg/l as respectively. So the impact of addition of mixtures of enzymes (Lipase (L), Amylase (AM) and Protease (P)) at concentration shown in research, under temperature 20˚and 37.5˚C.pH 6.5-7.2, the duration of fermentation is 12 days. The amount of salinity is ranged between (1004 – 1474) micromhos/cm. The results showed that the addition of any digestive enzyme to sewage water increases biogas production at least10:20 % in short retention time. However, to get maximum biogas production, it is necessary to add at least two or three digestive enzymes simultaneously to sewage water. Up to two different digestive enzymes can increase biogas production from sewage water. For example, biogas production was increased 20% and 80% after using pepsin only and a mixture of pepsin and Ox bile extract respectively. The results also showed that the addition of digestive enzymes to the sewage water increases biogas production at 37.5˚C over that at 20˚C.

Sustainable Energy from Waste: Opportunities and Technologies for a Cleaner World[Full-Text ] Reji ShajiEnergy generation from waste plays a vital role in sustainable energy security and waste management. Energy production and environmental aspects are analyzed for four alternatives based on different technologies: combustion with energy recovery, gasification, anaerobic digestion, and fermentation. The advantages of these technologies are mainly the significantly reduced waste volume for landfilling, the reduction of total greenhouse gas emissions, for generating electricity or co-generation of electricity and heat. With waste to energy, waste becomes an important source of renewable energy, moderating the climate change effects and saving earth’s valuable raw materials and resources. The integration of renewable energy sources within the boundaries of existing energy production systems has emerged as a promising and sustainable policy towards addressing the growing global energy demand. This paper provides technologies that can be incorporated into real world solutions and can serve as the foundations for future research.
