Abstract: The use of clean energies in the design and execution of buildings in the past decade has been very much considered [1, 3]. In this regard, a new generation of buildings that are designed and constructed to environmental aspects in the design and construction of structures Attention has been developed. In green buildings, renewable energy is used to provide part of the energy of the building. In addition, during the construction phase of these buildings from the design stage to the operation, it is tried to minimize the possible contamination of the project in the construction process, materials and construction materials, and After the operation, enter the environment. In the case of this type of project, there has been a lot of research that led to the establishment of greenfield design, construction and control companies [4, 6]. In these buildings, the design process is carried out in such a way that, in addition to the amount of energy and materials (natural and artificial) (minimized in the construction of the building, along with that site, the site of the project is also selected locally and the directions of the building It is located in such a way that environmental conditions can best be used to provide the energy needed for the building.

Abstract: These classes are notused as desired output and the network will find them indirectly. So training algorithm, in addition to weights must specify desired outputs. We call this algorithmUnspecified Desired Output Supervised (UDOS) learning algorithm. To find the network weights, the extended MSE criterion is developed which measures the quotients of both class tightness and class separation. Despite the complexity of this multi-objective optimization task, the results of this study are clear.UDOS succeeded in achieving superior performance than conventional methods. It is applied to the specific specific problem of keystroke identification, with success.

Abstract: The present-day tectonic movements in Iran are largely the result of the North-South convergence between Eurasia and Arabia with a rate of about 25 mm / year. It is expected that the compressive state applied to the Alborz (southern shore of the Caspian Sea) leads to a possible large vertical movement along major defects. In the framework of a cooperation program between Iran and France, absolute gravity measurements (FG5 # 206) as well as GPS campaigns have been carried out since 2000 and are repeated each year. The measurement portion will be used to renew Iran's gravimetric network (9 sites) and the repetition of 3 co-located sites (Abali near the Mosha fault, Tehran (NCC), and Chesmeh-Shour in the stable central Iran) will help in understanding the vertical movement in Alborz. After two initial series of measurements in 2000 and 2001, some preliminary results suggested an increase of 1 cm / year for the Abali site. A new campaign has been done in October 2002 and we are reporting here about new results related to the tectonics of Alborz

Abstract: In this paper, a novel fault location method for three terminal power transmission lines is proposed. This algorithm is based on the TT-transform for extracting the high frequency components of the current signal generated by the fault. By applying this transformation to different modes of current signals at all terminals, the arrival of traffic signals from the fault point to each terminal is inspected, whereby the fault location and fault section can be estimated. After simulating different fault conditions by ATP / EMTP software, MATLAB is used for processing fault data and calculating fault location. Various conditions and problems that maybe faced with fault location are considered in paper

Abstract: In this study, attempts were made to report on a corpus-based comparative analysis of the five processes involved in medical and applied linguistics abstracts. For this purpose, two examples of abstract, 70 applied linguistics and 70 medical, were selected as our corpus. These abstracts were analyzed by identifying the Hallidays transitivity system which includes 6 process types. These processes are classified under six headings: material, relational, behavioral, mental, verbal and existential. As the results show, the material and relational process types gained the highest positions among the other types of processes both in medical and applied linguistics abstract. Mental and existential gained the lowest position among other process types in both the medical and applied linguistics abstracts and behavioral process was omitted, because there was no occurrence in our corpus. The pedagogical implication of the present study for material developers is that they should conduct moves on analysis of various scientific texts to select appropriate materials for their publications.

Abstract: The current study was conducted in Abbas Abad Industrial Park of Tehran and aimed to analyze the mediating role of job satisfaction between job organization and job performance of 200 employees in 10 manufacturing companies. After distribution of questionnaires among respondents, 178 usable questionnaires were returned. The research method used for this study is descriptive-correlation. Furthermore, the analysis was carried out using Structural Equation Modeling (SEM). The factors analysis and the findings show that there is no significant relationship between job organization and job performance. But, Job organization will positively affect the job satisfaction of employees. Moreover, job satisfaction has a significant positive impact on employees' job performance. Therefore, the mediating role of job satisfaction between job organization and job performance has been established. Furthermore, a number of suggestions on managerial implementation were proposed.

The energy intensity of Denver's waterincluding supplying water and treating wastewater is 821 kWh / AF. Parker Water andSanitation, in contrast, uses a constant amount of energy to pump the groundwater from the Danube Basin aquifers. The energy intensity of the water in Parker is averaged 4,494 kWh / AF-groundwater pumped from deeper portions of the aquifer is even more energy intensive. Importantly, the new watersports that the Front Range cities hope to develop will be more energy intensive than existing supplies. Groundwater pumped from greater depths, surface waterconveyed over long distances, and water treated to higher standards (ie using UV radiation) will require more energy than today's water supplies. By contrast, water conservation can provide significant savings on energy while saving customers money and Reducing the state's greenhouse gas emissions.

Abstract: Mesoporous materials have attracted much attention not only due to porous features for adsorbents and catalysts but also due to electronic, magnetic, and optical properties for advanced devices. Silica spheres with mesoporous structures have potential applications in drug storage and release, confined-space catalysis, separation and energy storage. In this study, mesoporous silica spheres were synthesized by a sol-gel / emulsion approach, in which the cetyltrimethylammonium bromide (CTAB) surfactant was used to stabilize and direct the hydrolysis of the oil droplets of tetraethoxysilane (TEOS). In this method, the mixture of water and ethanol was used instead of water in a conventional oil-in-water emulsion system to improve the oilseed's stability, thus allowing for the preparation of silica spheres with improved size distribution. The diameters of the silica spheres were in the range from 300 to 400 nm. BET surface areas of the silica spheres were determined to be high up to 1208 m2g-1 and their pores were about 2.66 nm, as determined by the BJH method.

Abstract: This contribution introduces a new elastoplastic damage model for constitutive modeling of semi-brittle geomaterials like argillaceous formations showing two irreversible phenomena. The model deals with the plastic behavior of such a medium by a new thermal version of the Barcelona Basic Model. In addition, the micromechanical definition of damage and phenomenological concepts of damage propagation are combined in the framework of Continuum Damage Mechanics (CDM) for damage modeling. Damaged effective stress variables are used for the formulation of elastoplastic behavior laws. The plastic yield is a damage dependent one. The model has been implemented in -STOCK Code and the mechanical aspects of the model have been validated by comparing numerical results with reference experimental results of argillites and elastodamage model results

Abstract: This study primarily aims at developing structural equation models of knowledge management enablers in small and medium enterprises. The study was conducted as an empirical experiment to provide a structural equation model of the factors affecting knowledge management enablers. To this end, following a broad exposition of the literature on knowledge management in general and knowledge management enablers in particular, a selection of 300 company managers was selected from among selected individuals of 1151 individuals. The data was collected from the available documents, by conducting interviews and administering aquestionnaire to the participants. The reliability of the questionnaire was calculated at 0.90. The study adopted a non-experimental method and a survey design. In this regard, a structural equation model was developed to explain the factors affectingknowledge management enablers using correlational statistical tests, both direct and indirect correlations between variables and interactive regression equations in the form of path analysis. The statistical analysis was conducted using SPSS and Lisrel software. The results showed that the seven variables derived from the four components of knowledge management enablers – culture (collaboration, trust and learning), organizational structure (formalization and centralization), employees and information technology support – confirmed the accuracy of the developed structural equation model. All the variables, except for information technology support, have influencedknowledge management enablers at variable intensities both directly or indirectly or interactively. Based on the coefficient of the structural equation model, the collaborative and trust subcales made the most significant direct effect on knowledge management enablers, while other variables including cooperation, employees, learning and organizational structure component components subscales assumed less importance in this regard. The paper concludes with discussion and comparison, the conclusion, applicable managerial implications and recommendations for future studies.
