Enhancing gas turbine plant performance in hot climates through fogging technique [Full-Text ] Aly M.El-Zahaby, Y.A.F. El-Samadony, Magda K. El-Fakharany, Ali A. GheathTemperature of the gas turbine inlet-air has a significant effect on power output and hence its efficiency. At high ambient temperatures, there is a significant loss in air mass flow rate, and hence leads to reduce the gas turbine produced power. In the present work, the effect of lowering the compressor intake-air temperature by means of a fogging evaporative cooling on the performance of gas turbine is studied numerically. Water is atomized through compressor intake to perform evaporative cooling. The effect of air inlet temperature and relative humidity, air and water mass flow rate, water droplet injection speed and water droplet diameters are studied. Unlike previous work, the effect of cooling the spray water injected droplet is studied. The results show that air to water thermal condition and water droplet size play an impotent role in evaporative cooling processes. Cooling inlet air temperature may increase in the turbine output power by approximately 1to 8.1%. Finally, a good agreement between numerical and experimental case study is obtained.

NOVEL MULTI OWNER DATA SHARING GROUP KEY PROTOCOL[Full-Text ] MaheshKothuru,PraveenaPothina Cloud computing provides an economical and efficient solution for group resource sharing among cloud users due to the character of low maintenance. A challenging issue is sharing data in a multi-owner manner while preserving data and identity privacy from an untrusted cloud due to the dynamic nature of the membership. The proposed scheme provides privacy and complexity while handling the data sharing over cloud. To preserve data privacy, the basic solution is to encrypt data files, and then upload the encrypted data into the cloud. Unfortunately designing an efficient and secure data sharing scheme for groups in the cloud is not an easy task due to following reasons. First, the identity of the data owners must be preserved. Second, the data owner should be able to utilize all the services provided by the cloud storage service provider. Our proposed technique works with improved AES secret sharing group key mechanism and data can be uploaded to the server after the encryption of the content by using the secret group key. When a new member joined the group, new granted users can directly decrypt uploaded data files before their participation without contacting with data owners.

Geochemistry, Classification and Geotectonic study of the Basement Rocks Around Orin -Ekiti, South West, Nigeria[Full-Text ] Obasi, Romanus AyoolaRock geochemistry, classification and geotectonic setting of the basement rocks of Ado Ekiti are studied using data analysed by X-ray fluorescence (XRF) at the Central laboratory of Stellenbosch University, South Africa. The data revealed an unusually low (40.13--40.77%) and moderate (52.10--70.22%). SiO2 contents that correspond to approximately basic (40-52wt %) and acid ( > 66.0 wt %) rock compositions respectively in the rock suite. CaO contents range from 1.71 to 12.38. SiO2, CaO and Na2O + K2O relatively show a contrasting variation, where CaO decreases with increasing SiO2 and Na2O + K2O. Harker variation plots of oxides; NaO2 MgO, TiO2, Fe2O3, Al2O3, CaO with SiO2, showed a negative trend while K2O showed a positive linear trends with SiO2. The variation in the trends suggest different sources of materials mixed up in the rocks during metamorphism. An analysis using the aluminium saturation index (ASI) defined by molecular ratio Al2O3/Na2O+CaO+ K2O reveal that the ratio (0.8 and 1.52) displays two contrasting data where four samples 1, 2, 3 and 10 are less than one (1.1) and six samples (4-9) are greater than unity (1.1) implying that some of the basement rocks are metaluminous ( I-Type) while others are peraluminous (S-Type) granitic rocks thus collaborating with mixed sources of materials. The rocks under study can be classified as calcic, alkalic and calc-alkalic based on the crossplots of Na2O+K2O versus SiO2. They are granite, quartz monzonite, gabbroic diorite and the granodiorite based on the plot of Na2O+ Na2O against SiO2. Some of the rocks are iron -rich (ferroan) while others are magnesium rich ( magnesian) . A plot of K2O/Na2O versus SiO2 classified the geotectonic setting of the rocks into the passive margin and the oceanic island arc .

MODELLING OF CHAMBER PRESSURE FOR ROCKET NOZZLE ALTITUDE COMPENSATION[Full-Text ] Humphrey Iortyer PhD, Nongo Sesugh,Kwaghger Aondona PhDThe optimum thrust of rocket engine is being delivered when the nozzle exit and ambient pressures are balanced. This poses a challenge with the operation of rocket engines when ascending altitudes since the ambient pressure decreases with the changing altitudes. There have been solutions designed to counter the effect of this variation in pressure with special rocket nozzles such as Aerospike nozzles, Deflection nozzles, extended nozzles, etc. However, these special nozzles add up to weight, mechanisms, rocket system engine staging and cost of production. This paper therefore looks at the rocket model that will enable thrust optimization along altitudes by determining (upstream) chamber pressure values with regards to the ambient pressure.

Use of Opening Range Breakout in an Online Trading System[Full-Text ] Neelansha TrivediThe goal is to build an online trading application for a global financial institution that invests in capital across multiple asset classes, where many a times challenges are faced in keeping track of all the investment decisions by various asset managers in the firm and also in maintaining accuracy of data which is shared by different users in the same office and also across geographies. For such an organization to earn significant profits, which deals in trading daily, it is important to make use of strategies in order to buy or sell securities. Thus, in order to help a trader to make transactions on the trading terminal we make use of a technique called Opening Range Breakout (ORB). Opening Range Breakout is a trading system which makes use of technical analysis for high accuracy results in the field of intraday trading as well as positional trading. ORB makes use of strict rules, indicators such as resistance, support, exponential moving averages etc. and good knowledge of the overall market in order to increase profit rates dramatically. Opening Range Breakout (ORB) is widely used by professionals and analysts who predict how the market will act for a particular day. However, in practice, for a global institution it is important to have their own thorough technical analysis to help portfolio managers and traders get profitable trading opportunities. In this project, we will try a novel approach which employs deep learning to tackle the problem.

Asynchronous Programming for Big Data using K-Mean Clustering[Full-Text ] Md. Mizanur Rahman, Ohidujjaman, Mohammad Nurul HudaClustering is very problematic on big data set in synchronous programming as well as time consuming. Finding optimal result from big misaligned data set is precarious because lack of seamless data pattern. This study emphasizes on reducing time fact and deployment of asynchronous program rather than synchronous model on big data. However, we provide an easy and flexible model named UACM (Unified Asynchronous Clustering Model) for clustering on multi dimensional, misaligned and big data set. The UACM replica segments big data set for parallel processing depending on segmentation of microprocessor. This model uses small unit of process (thread) as per the data set. The UACM architecture is also cost minimizing regarding hardware. This model evaluates the time fact between synchronous and asynchronous programming on large and misaligned data set. However, we implement the UACM model in real-time platform without help of clustering tools.

A Critical Review of Distribution Substation System Reliability Evaluations[Full-Text ] Ayodeji A. Akintola and Claudius Ojo A. AwosopeThe significance of a reliable distribution system is hinged on the fact that even if the generation and transmission of a power system are highly reliable, an unreliable distribution system will mean that there will be poor supply of energy to the consumers. Therefore, there must be ways of measuring the reliability of power distribution systems according to given standards in order to help inform the system engineers on the causes of interruptions. This will in turn help in proffering methods of accomplishing a more reliable distribution system. There are established basic methods of assessing the reliability of this system and different researchers engage the one best suited for the analysis they intend to carry out. Moreover, going through previous published works on distribution system reliability evaluation, insight is given into why a distribution behaves below standard and how it could be possibly improved. This paper presents an overview of the basic methods used in reliability assessment with the frequently used reliability indices and a critical review of published works by authors in carrying out the reliability evaluation of different power distribution systems based on these various methods.
