Estimating future supplies of this valuable commodity is an important economic and strategic endeavor. However, world gas supply forecasting has proved difficult because its exploration, transportation, and customer bases depend so heavily on fluctuating economic factors. Gas production fluctuations from several countries were affected by the relationship between gas and oil industries, economic burdens, and governmental-policy implementations. This work presents innovative approaches for analyzing and forecasting natural gas supply for individual countries and the world. These new methods include the multicyclic modeling, artificial intelligence technology, and time-series analysis. Most industrialized countries are depleting their gas resources much faster than are developing countries. Fuel switching and gas dependence by industrial and commercial sectors and production decline of crude oil in these countries are among the reasons for the high depletion rate. Russia and major Arabian Gulf countries will be major sources of world gas supply representing about 62% of world s future recoverable conventional gas. ····· 10361100689

Further, integrating ancillary data like digital elevation model, slope, texture, contextual information, etc. into spectral bands is difficult in such classifiers, because ancillary data results in a non-Gaussian distribution of the resultant data. Hence, generating a satisfactory classified image from the higher spectral and spatial, and high-dimensional data is one of the present-day challenges in RS data analysis. This thesis is aimed at developing an advanced classification strategy by integrating a non-parametric J4.8 decision tree classification algorithm and a texture based image classification approach on a panchromatic sharpened IRS P-6 LISS-IV (2.5m) imagery. Attempt has also been made to provide answers through empirical studies to some of the dubious issues and contradictory findings in RS image classification with regard to image evaluation metrics, statistical feature selection criteria and border-effect. ····· 1036199887

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Liquid transportation through pipelines is one of the power consuming sectors in the oil and gas industries due to the energy losses during flow. Thus, improving the flow in pipelines has become one of the important and strategic needs in modern industrial applications. The energy losses are mainly attributed to drag. The word (drag) may be defined as the resistance force parallel to the direction of fluid flowing over a solid surface. Drag force may be expressed by two components: skin friction component which is equal to the stream wise component of all shearing stresses over the surface, and pressure drag component, which are equal to the stream wise component of all normal stresses. The present book introduces a new, novel and environmentally friendly drag reducing agent is introduced.

Analysis of kinetic data shows that the initial adsorption of cadmium is rapid for both the biosorbents, however, equilibrium agitation period is about 5 h for lemon peel and 3 h for green coconut shell powder. The adsorption process for both the biosorbents follows pseudo second order kinetic model. Langmuir isotherm model gives better prediction on adsorption equilibrium than Freundlich isotherm model. The Langmuir maximum adsorption capacity (qmax) for lemon peel and green coconut shell powder is found to be 11.24 mg/g and 14.49 mg/g respectively. The values of thermodynamic parameters such as Gibb s free energy change ( G°), enthalpy change ( H°) and entropy change ( S°) for these experiments indicate the spontaneous and exothermic nature of the processes. ····· 1036199402

Discontinuous, discrete steel fibers of short lengths smaller in diameter have been used to improve the tensile and flexural strength of structural elements subjected to various loading conditions. Although the introduction of fibers into concrete reduces its workability, yet there is a significant improvement in the material behavior. The brittle characteristic of concrete is converted into a ductile one. Use of fibers alters the behavior of the fiber-matrix composite after it has cracked, thereby improving toughness. The goal of the work is to establish new relationships and to verify the available relationships between the various properties of Steel Fiber Reinforced Concrete (SFRC). Linear relationship between the flexural tensile strength and cube compressive strength are proposed for various percentages of fibers. The results indicate that fiber content in the range of 0.5% to 1% provide excellent toughness to normal strength concrete as compared to high strength concrete. ····· 1036199287· 1 · ::::: · 18 ·· 19 ·· 20 ·· 21 ·· 22 ·· 23 ·· 24 · ::::: · 47 ·
