Different Models of Wind Speed Prediction; A Comprehensive Review[ ]


The energy crisis witnessed in the early seventies is a serious problem that had happened in the universe. Hence, induction of renewable energy into electrical power generation mix can serve as an alternative source to cater for the limited reserve of fossil fuels. Wind energy is promising and has emerged as one of the safest, cleanest and fastest growing renewable energy in the recent years. The bottleneck of this type of emission free energy is the variability, stochastic, unpredictable and complex nature of the wind speed. To harness the energy content in a wind efficiently, it’s of utmost importance to accurately predict wind speed and energy with minimum accepted errors for security and economics of wind power utilization. For this reason, it becomes necessary to appraise different types of models used in the wind energy forecast. This paper present review of available wind speeds and power prediction models and discuss their applications and current developments. Moreover, the survey also highlights an overview strength and weakness of these models.

Treatment of liquid waste by sorption of toxic metal (Cr) using one-step steam pyrolysis corn cobs activated carbon[ ]


In the present study, a low-cost adsorbent is developed from the naturally and abundantly available biomass (corn cobs). The removal of Cr (VI) from synthetically prepared aqueous solutions and laboratories effluent of Nuclear Materials Au-thority was studied. The batch experiments were carried out to investigate the effect of type of the biomass and method of preparation, initial pH, contact time, temperature, adsorbent weight, and initial Cr(VI) concentration. The equilibrium data for the adsorption of Cr(VI) on steam pyrolyzed at 750 oC corn cobs activated carbon (CC-S75) was tested with various adsorption isotherm models; Langmuir, Freundlich and Tempkin equation. The Langmuir isotherm model is found to be the most suitable one with maximum adsorption capacity of 109.53 mg g-1 at an initial pH value of 1. The adsorption process follows the second-order kinetics. Desorption of Cr(VI) from loaded CC-S75 using acid and base exhibited a higher desorption efficiency. The interference of other ions which are generally present in the laboratories effluent streams on the Cr(VI) removal was investigated.

Surface engineering of solid supports; Cellulose, Nitrocellulose and Nylon to increase the efficiency of antibody immobilization in diagnostic systems[ ]


Immobilization of antibodies is a critical stage for design and manufacturing of sensitive biological sensors. In this study, in order to increase the capacity of antibody capturing by the supports, different materials and polymer layers such as Cyanogen bromide, Acetonitrile, PEI and MAMEC were used for processing the surface of Cellulose, Nitrocellulose and Nylon, respectively. Increasing the surface charges in nitrocellulose and creating new active groups on the surfaces of activated nylon and cellulose were the most important chemical modifications on the mentioned solid supports. Assessment of immobilized antibody showed that the chemical modifications applied on the surface of supports have had significant effects on increasing their capacity to accept antibody, compared to control samples. Efficient immobilization of antibody on the supports can increase the sensitivity of immunochromatographic-based diagnostic systems. Immobilization processes can alter the physiochemical features of supports such as their capillarity, flexibility, surface charges, delicacy etc. which may intensively influence the quality of immobilization.

A Novel Method for Placement of Batteries in a Distribution Network[ ]


That storage device like batteries can substantially improve performance of power distribution system is well established. These improvements can include attributes like reduction in line loading, reduction in losses, improved voltage profile, better voltage control by minimizing voltage deviations. The extent of improvement can provide clue to placement of the batteries. In the literature, the placement are generally based on only considering one of these attributes. This paper attempts to take an integrated approach considering simultaneous effect of all the above attributes. The feasible plans are generated by eliminating a number of generated configurations. Analytical Hierarchy Process (AHP) is used to assign the weights to different attributes. Data Envelop Analysis (DEA) is used to judge the feasible plans on common platform considering normalized values of the at-tributes. The plans with high efficiency can help in decision on placement in an integrated manner with proper trade-off of attributes. The proposed methodology is illustrated on a IEEE 14 and 30 bus distribution system.

Pre Defined Trajectory Algorithm for Mobile Anchor Based Localization in Wireless Sensor Networks[ ]


Accurate and low-cost sensor localization is a critical requirement for the deployment of wireless sensor networks in a wide variety of applications. Many applications require the sensor nodes to know their locations with a high degree of precision. Various localization methods based on mobile anchor nodes have been proposed for assisting the sensor nodes to determine their locations. However, none of these methods attempt to optimize the trajectory of the mobile anchor node. Accordingly, this project presents a path planning scheme, which ensures that the trajectory of the mobile anchor node minimizes the localization error and guarantees that all of the sensor nodes can determine their locations. The obstacle-resistant trajectory is also proposed to handle the obstacles in the sensing field. Later this path planning algorithm is adjusted so that it suits most of the effective localization algorithms. The performance of the proposed scheme is to be evaluated through a series of simulations with the ns-2 network simulator.

Although waterflooding is an effective process, surfactant flooding is used to recover oil from reservoirs by wettability altera-tion and interfacial tension reduction. Economical effectiveness is a main challenge in feasibility of any EOR method. In this study, we compare oil recovery of both surfactant and water flooding in Reservoirs with various conditions. One of the im-portant optimization variables is well placement. Various methods have been suggested for this problem. Among these, direct optimization, although accurate, is impossible due to the number of simulation required. Optimal placement of up to three injection wells was studied at two fields. One of the Iranian conventional field and a hypothetic fractured field. Injection rate and injection time was also optimized. The net present value of the surfactant flooding projects was used as the objective function.

Kinetic Energy Recovery System[ ]


The introduction of Kinetic Energy Recovery Systems (KERS) is one of the most significant technical introductions for the Formula One Race. Formula One have always lived with an environmentally unfriendly image and have lost its relevance to road vehicle technology. This eventually led to the introduction of KERS.KERS is an energy saving device fitted to the engines to convert some of the waste energy produced during braking into more useful form of energy. The system stores the energy produced under braking in a reservoir and then releases the stored energy under acceleration. The key purpose of the introduction was to significantly improve lap time and help overtaking. KERS is not introduced to improve fuel efficiency or reduce weight of the engine. It is mainly introduced to improve racing performance.

Using Dulong and Vandralek Formulas to Estimate the Calorific Heating Value of a Household Waste Model[ ]


In this paper, Dulong, modified Dulong, Vandralek and direct formulas have been used to calculate the higher calorific value (HCV) and lower calorific value (LCV) of the waste model of the combustible fraction of the town of Ouagadougou. Different results from these formulas have been compared to experimental results obtained form measures made with a semi-industrial calorific heating value measurement apparatus. Comparison shows that the Dulong and Vandralek HCV formulas calculation gives us the lowest relative errors or differences in respect of the experimental LCV. On contrast, the direct LCV calculation formula give use the biggest relative error. This suggests that Dulong and Vandraleck formula could help quickly estimate the calorific value of a household waste combustible fraction model.
