Short Report on: Possible directions to Auctions with Cryptographic pre-play
Amjed Shareef
Computer Science , 2012,
Abstract: In auction theory, cryptography has been used to achieve anonymity of the participants, security and privacy of the bids, secure computation and to simulate mediator (auctioneer). Auction theory focuses on revenue and Cryptography focuses on security and privacy. Involving Cryptography at base level, to enhance revenue gives entirely new perspective and insight to Auction theory, thereby achieving the core goals of auction theory. In this report, we try to investigate an interesting field of study in Auction Theory using Cryptographic primitives.

Amjed Ali, Ijaz Rasool Noorka
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.45131
Abstract:

Water is the most important factor limiting crop productivity at different growth stages of crop growth and development. The study was conducted to investigate the effect of irrigation scheduling on sunflower hybrid (Hysun-38) at vegetative versus reproductive stages during spring season 2010. The trial was laid out in randomized complete block design (factorial arrangement), replicated thrice, having net plot size of 3.5 m × 9 m. The treatments comprised of irrigation application of 75 mm each, at different growth and development stages. viz., I1 = irrigation at plant establishment, I2 = irrigation at plant establishment and irrigation at vegetative phase, I3 = irrigation at plant establishment, irrigation at button stage and irrigation at flowering, and I4 = irrigation at plant establishment, irrigation at vegetative phase, irrigation at button stage and irrigation at achene’s formation. Days taken to 50% flowering was highest in I2, where irrigation was applied at plant establishment and vegetative phase, and in I4 treatment , where irrigation was given at seedling establishment, irrigation at vegetative phase, irrigation at button stage and irrigation at achene’s formation. Leaf area index at different growth intervals was significantly affected by irrigation levels. Crop growth rate was highest for treatment I4. Plant

A Binary ART Neural Network Methodolgy for Computer-Aided Process Palnning of Milling Parameters
Amjed Al-Ghanim
Information Technology Journal , 2002,
Abstract: Artificial neural network have been successfully employed for providing efficient solutions for decision making problems and gained increased significance for their use in computer integrated manufacturing environment as effective tools for improving productivity and decision quality. The function of process planning in machining operations is a prominent one for neural network applications since it has direct impact on overall manufacturing productivity. This paper presents analysis and results of applying self-organizing neural networks to the selection of machining parameters of milling processes. The importance of this approach stems from the ability of neural nets to handle vague or ill-structured problems and the inherent capability of generalizing solutions to unseen problems. Furthermore, self-organizing neural networks do not require full knowledge of `output` data needed during the training phase; only a small portion of the data is needed for model calibiration. Simulations using ART1 neural model were applied to the selection of the tool material type and tool entry strategy, and the results demonstrated a high potential for the development of neural network modules for practical applications.
Effect of nitrogen on achene protein, oil, fatty acid profile, and yield of sunflower hybrids Efecto de nitrógeno en la proteína, aceite, y perfil de ácidos grasos del aquenio y rendimiento de híbridos de girasol
Amjed Ali,Sami Ullah
Chilean Journal of Agricultural Research , 2012,
Abstract: Seed yield and achene oil yield are the main determinants for N application rates rather than seed composition. Nitrogen plays a critical role in producing unsaturated fatty acids (oleic and linoleic acids), which are the main factors determining sunflower oil quality (Helianthus annuus L.). Studies were conducted on the effect of N fertilization on seed yield, achene oil yield, and quality parameters of sunflower hybrids for two successive years (2010 and 2011) in a split plot arrangement under a randomized complete block design. The hybrids (Hysun-33 & S-278) and N levels (0, 75, 150, and 225 kg ha-1) were allotted in main and sub-plots, respectively. Increasing N levels resulted in steady increases in yield, protein contents and linoleic acid, whereas oil contents and percentage of oleic acid responded negatively during both years. At the same time, crop oil yield was positively related to increased N supply with higher achene yield (AY). Palmitic acid varied from 5.27 to 6.42 % and stearic acid ranged from 2.27 to 2.95%. Hybrid S-278 exhibited significantly (P < 0.05) higher AY (3380 kg ha-1), oil content (42.11%) than Hysun-33 (2968 kg ha-1 and 40.75%, respectively), while the opposite was true for protein content. Oil yield varied in response to N fertilizer, with a range of 34 to 37% providing the best quality traits in both seasons. Parece racional que el rendimiento de semilla y rendimiento de aceite de aquenio sigan siendo el foco determinante para tasas de aplicación de N en lugar de la composición de la semilla. El N parece jugar un papel imprescindible en la proporción de ácidos grasos insaturados (ácidos oleico y linoleico), factor principal que determina el aceite de girasol (Helianthus annuus L.). Los estudios fueron realizados para evaluar el efecto de la fertilización N en el rendimiento de semilla, rendimiento de aceite de aquenio, y parámetros de calidad de híbridos de girasol por 2 anos sucesivos (2010 y 2011) en un diseno de bloques completos al azar con arreglo de parcelas divididas. Los híbridos (Hysun-33 y S-278) y niveles de N (0, 75, 150 y 225 kg ha-1) fueron asignados a parcelas principales y sub parcelas, respectivamente. Niveles crecientes de N aumentaron de manera estable el rendimiento, contenidos de proteína y de ácido linoleico en el aceite, donde contenidos de aceite y porcentaje de ácido oleico respondieron negativamente durante ambos anos. Al mismo tiempo, el rendimiento de aceite del cultivo permaneció positivamente relacionado al gran suministro de N dando la ventaja de mayor rendimiento de aquenio (AY). El ácido p
Optimization of Air Quality Monitoring Network Using GIS Based Interpolation Techniques  [PDF]
Mohammed M. Shareef, Tahir Husain, Badr Alharbi
Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.76080
Abstract:

This paper proposes a simple method of optimizing Air Quality Monitoring Network (AQMN) using Geographical Information System (GIS), interpolation techniques and historical data. Existing air quality stations are systematically eliminated and the missing data are filled in using the most appropriate interpolation technique. The interpolated data are then compared with the observed data. Pre-defined performance measures root mean square error (RMSE), mean absolute percentage error (MAPE) and correlation coefficient (r) were used to check the accuracy of the interpolated data. An algorithm was developed in GIS environment and the process was simulated for several sets of measurements conducted in different locations in Riyadh, Saudi Arabia. This methodology proves to be useful to the decision makers to find optimal numbers of stations that are needed without compromising the coverage of the concentrations across the study area.

Journal of Agricultural Chemistry and Environment (JACEN) , 2017, DOI: 10.4236/jacen.2017.61003
Abstract: Improving the soil and biomass with coal is estimated at the international level as a way to enhance soil productiveness, fertility and also to mitigate climate change. Biochar employed to improve land scope and impound carbon, is attracting a great deal of attention. Its characteristics of chemical, physical and biological properties, containing big surface area, CEC (Cation Exchange Capacity), high water-holding capacity, size of pore, volume, distribution, and element composition, affect its recognized influences, particularly on microbial communities. These are discovered in the agriculture lands, lands remediation and composting. However, incomplete information existed about biochar for several farmers or peasants in agriculture scope. Therefore, farmers or peasants and gardeners are facing new opportunities and defiance each day, from feeding global extending and expanding population, whilst meeting severe new emissions requirements, to create more food on fewer land area while reducing their environmental emissions. Widespread application and utilization of biochar in agricultural scope, forestry production, energy, environmental protection and additional areas, has interested awareness by scientists and investigators inside and/or outside the country. The objective of this paper is to provide a guide for the farmers or peasants and gardeners with an essential information about biochar and what the ability of biochar can be achieved in the soil, and which can provide the scientific reference for the biochar application, and to get high yield and good quality of crops in all of different soils.

Open Journal of Geology (OJG) , 2018, DOI: 10.4236/ojg.2018.87039
Abstract: Gold mineralization at G. R. Halli is located along the Central shear zone of Chitradurga schist belt, extending from west of Gonur, through east of G. R. Halli and C. K. Halli to east of Honnemardi, roughly parallel to stratigraphic units. The NNW-SSE trending shear zone has a width of 0.5 to 1.5 km shows extensive carbonatization of metabasalts and the associated lithologies confined to NNW-WNW trending arcuate brittle-ductile zone. The sheared and silicified contact zones between carbonaceous argillite and schistose metabasalt form the potential sites for localization of mineralization. The gold is associated with sulphides mainly pyrite, arsenopyrite, galena, sphalerite, minor chalcopyrite. Textural relationship indicates two stage sulphide mineral assemblages co-relatable with two stage fluid ascents having temperature of homogenization between 125°C and 256°C. It is a typical epigenetic lode gold system, which got affected by later deformation.

Shareef M. Shareef,Hamid Jahankhani,Mohammad Dastbaz
International Journal of Electronic Commerce Studies , 2012,
Abstract: E-government systems world are employed all over the world in an attempt to utilize information and communications technology (ICT) to improve government services provided to a range of stakeholders. In employing these systems, governments aim to become more accessible, effective, efficient, and accountable to their citizens. To improve the quality of service delivery to the public, government institutions have to cooperate and manage the shared resources and information flows. The aim of this paper is to analyse one of the established e-government stage models, such as the United Kingdom, and to identify possible opportunities to adopt them for use in the regional governments of developing countries. The study revealed that the analysed model cannot be adopted for use in the Kurdistan Region of Iraq (KRI) due to various critical issues relating to ICT infrastructure, e-readiness, legal framework, cultural attitude, education level, political process, and others.

Amjed Ali and Ijaz Rasool Noorka
Soil & Environment , 2013,
Abstract: This study conducted during autumn season, 2010 investigated the effect of nitrogen and phosphorus on sunflower hybrid Hysun-33. The experiment was planned in randomized complete block design (factorial arrangement), with three replication, having net plot size of 3 x 7 m. The experiment comprised of 9 treatments, three levels of nitrogen and phosphorus, viz., 85, 135, 185 kg N ha-1, and 50, 75, 85 kg P ha-1. Nitrogen affected all estimated characters significantly, except plant population, while, phosphorus did not show significant effect on plant population and plant height. All other parameters, as leaf area plant-1, head diameter, 1000- achene weight and achene yield were affected significantly by different nitrogen and phosphorus levels. Interactive effects of nitrogen and phosphorus were significant in all these cases. The highest achene’s yield (2584 kg ha-1) was obtained with the application of 135-75 kg NP ha-1as against the lowest (1491kg ha-1) at 85-50 kg NP ha-1.
