Large and extensive area of thin reservoir in Songliao basin,these reservoirs' physical parameters' relationships are not linear, nor the function can be expressed. Most of the relationships of parameters are distributed by kinds of cloud shapes.If the cloud model is applied to the thin reservoir prediction, which can maximum reduce the fitting error between the two functions, especially between the two functions without linear and parabolic conventional relations, etc.The Cloud Transformation technology for reservoir porosity, permeability and other physical parameters prediction provides a scientific and effective method, also has a practical significance to the exploration and evaluation in oilfield .
Key words: Reservoir prediction; Songliao basin; Cloud transformation; seismic inversion
Tight oil as one of unconventional oil and gas resources are widely distributed, great potential. In recent years, with the development of shale gas and the volume of fracturing horizontal well technology, dense oil and gas has the potential to succeed in the areas of energy exploration and development has become increasingly active, is developing rapidly. The main layer "dessert" predict played a crucial role again when the reservoir development deployment position, aiming Songliao Basin Yingtai area as an example, from seismic attribute analysis are based on a study combining geostatistical inversion.
Keywords: Tight oil; Songliao Basin; Geostatistical inversion; Phase shift process;
Based on the comprehensive analysis of core、oil testing and logging data, this paper searched the cause of low-resistivity oil layer and high-resistivity water layer.Then oil-water layer logging interpretation chart was established by using RLLD and corrected RILD to identify oil-water layers. The log interpretation result shows there are 5 types of vertical oil-water distribution of single well in research area:pure oil layer type、oil to water layer type、oil-water layer type、pure water layer type、messy type. The vertical and horizontal oil-water distribution was finally concluded.
Key words:G region;PI reservoir; Oil-water layer recognition; Oil-water layer distribution

The ubiquity of laterite in this region of the world imposes the need for its utilization in concrete and road making works for the economic growth of the region. Laterite is the reddish soil layer often belying the top soil in many locations and further deeper in some areas, collected from the Vocational Education Building Site of the University of Nigeria, Nsukka. The paper presents the report of an investigation carried out to model and optimize the Poison ratio of Lateritic Concrete. The work applied the Scheffe's optimization approach to obtain a mathematical model of the form f(xi1,xi2,xi3), where xi are proportions of the concrete components, viz: cement, laterite and water. Scheffe's experimental design techniques are followed to mould various block samples measuring 220mm x 210mm x 120mm, with varying generated components ratios which were tested for 28 days strength to obtain the model: Ŷc = 0.33X1+ 0.27X2 + 0.45X3 + 0.52X1X2 – 0.02X2X3 . To carry out the task, we embark on experimentation and design, applying the second order polynomial characterization process of the simplex lattice method. The model adequacy is checked using the control factors. Finally a software is prepared to handle the design computation process to select the optimized properties of the mix, and generate the optimal mix ratios for the desired property.
Keywords: Optimization, Lateritic concrete, pseudo-component, Simplex-lattice, model adequacy.
Social networking has become a popular way for users to meet and interact online. Users spend a significant amount of time on popular social network platforms (such as Facebook, MySpace, or Twitter), storing and sharing personal information. This information, also attracts the interest of cybercriminals. In this paper, a step further is taken by addressing the issue of detecting video spammers and promoters.

Today, the quality of urban life is as the key concept in urban planning and different definitions of quality of life have been presented. At a glance, the quality of life can be defined as favorable environmental objective conditions and positive personal assessment of these conditions. Various scientific fields such as medicine, social sciences, geography, etc have studied the quality of life according to their expertise. So in this regard the goal of the present research is the assessment of the life quality of urban areas and the case study is the city of Fahraj. The research method is analytic-descriptive and based on library, documentary and field studies. The results of AHP model show that the criterion of E (Family life) with weight of (0.254) is in the first place and the criterion of B (material excellence) with weight of (0.121) is the last place.
Keywords: Quality of life, Urban areas, Fahraj, AHP Model
Religious tourism with the history related to the past centuries is one of the most common forms of tourism throughout the world which has constituted a considerable share in tourist activities. Experts of tourism industry believe that religious tourism has a great growth and development opportunity in Iran, which is related to its special religious and cultural situation in the region. Despite the existence of 8919 sacred religious locations in Iran, its religious tourism still lacks any kind of centralized and specialized organization. Today, tourism development is not possible in the absence of knowing the needs and satisfaction rate of tourists as well as their effective factors; this issue has been also specifically considered at national, regional, and international levels. Therefore, the present study aimed to measure the satisfaction rate of tourists and its effective factors in order to develop religious tourism in South Khorasan Province. This research was an analytical-descriptive work .ranking results of the effective factors for the satisfaction rate of religious tourists revealed that information quality for tourists gained 0.861 value score, life and financial safety 0.793 value, and environmental calmness 0.787 value, had a better position than others.
Keywords: Religious tourism, satisfaction, TOPSIS technique, South Khorasan.
