As Iran’s climate is arid and semiarid the ways of utilizingground water resources are of great importance. One of the regions affected by excessive exploitation of ground water resources is Hashtgerd plain in west of the Karaj region. The level of ground water has decreased by 2 to 4 meters during past ten years. To prevent further fall, artificial recharge plan is pat forth. The proposed region for this purpose is located in south of Kordan village, below Tehran-Tabriz railway and on the east bank of Kordan river. Water for artificial recharge is provided from Kordan river and the volume of feeding is 3.5 cubic meters per second on avarage from February to May. The weight of carried sediment (suspended substancest+bed load) by Kordan river during four month period of artificial recharge is estimated to be 123.68 thousand Tons. According to Schoeller diagram water of Kordan river is of good quality for drinking but sedimentation properties and can becategorized in C2S1 class according to Willcox diagram. Geologically, artificial recharge region is formed by Tehran allovium (C series) that belongs to plio - quaterner period. Form hydrogeologic aspects, this allovium plays important role in artificial recharge because experiments showed that transmissibility of proposed region is about 3500 square meters per day and its vertical and horizantal permeabilities are calculated to be 2 and 14 per day respectively. By using isobat maps, the height of aquifer is estimated to be 250 meters and storage coefficient is obtained to be 7 to 9 percent utilizing budget equation. After artificial recharge, Hassman, Hantush and Todd METHODs are used to calculate the increase of ground water level and dimensions of basins. According to Hassman METHOD the total surface area of basins are calculated to be 79562.12 square meters in which 6 basins that measure 60 x 200 meters can be designed.

Some experiments were performed around the Agricultural and Natural Resources Research Station of Islamabad-Gharb city in order to determine the economic evaluation of corn crop behavior to deficit irrigation and surge irrigation strategy in Islamabad-Gharb Area under ferrow irrigation. The statistical design of the research was Factorial design (as compound analysis in two years) in a randomized complete block design Which has two factors at 3 and 4 levels. Factor A (irrigation water quantity) and factor B (surface irrigation METHOD), so there was 12 treatments and 3 replications. The results showed that in different irrigation METHODs The highest net and net profit than the amount of water consumed at 2016 occurred of S1-2 treatment respectively 6. 46 and 2. 84 billion rials per cubic meter also at 2017 occurred of S1-2 treatment respectively 6. 49 and 2. 62 billion rials per cubic meter and in different irrigation regimes The highest net and net profit than the amount of water consumed at 2016 occurred of 75% water requirement treatment respectively 6. 98 and 3. 5 billion rials per cubic meter also at 2017 occurred of 75% water requirement treatment respectively 6. 91 and 3. 2 billion rials per cubic meter.

One of the obvious reasons for most disorders in network service provisioning is network path congestion. Congestion avoidance in today's networks is too costly and sometimes impossible. With the introduction of SDN, centralizing the equipment's control plane has become possible. This paper presents an enhanced METHOD named ESV-DBRA to avoid congestion in multi-tenant SDN networks. At first, ESV-DBRA monitors the traffic load and delay of all network paths for each tenant individually. Then, by merging the parameters obtained from the monitoring, the Service Level Agreements (SLA), and a novel proposed cost function, it calculates the cost of the network paths per tenant. As a result, traffic for each tenant is routed through the path/paths at the lowest possible cost from the tenant's perspective. Next, the bandwidth quotas will be calculated and assigned to the tenants over their optimal routes. Afterward, whenever congestion is likely to occur in a path, ESV-DBRA automatically changes the route or bandwidth of the tenants' traffic related to this path to avoid congestion. Related algorithms are also proposed.Eventually, simulations show that the proposed METHOD effectively increases bandwidth utilization by 10.76%.

The Qur'an contains religious values ​​for the advancement of man to happiness. The claim is that Quranic teachings are the basis of religious values; By choosing it better, the METHOD of proving religious beliefs can be extracted. This research tries to extract the METHOD of proving religious beliefs with a business approach and by using artistic forms with a descriptive and analytical METHOD and with a better selection of Quranic teachings. Based on the verses, the process was defined as the introduction to the institutionalization of religious values ​​in the businessman 1- Gaining self-knowledge (knowing the talents, capacities, existential dimensions and position of man in the universe); 2- Gaining monotheistic insight (knowing the origin and your relationship with the Creator); 3- Reciprocity is (knowing the destination and drawing the path of happiness in the universe). After the realization of these three stages, the beliefs must be proven through rational and scientific reasoning and penetrate, in this case, the acceptance of good qualities in the businessman will be facilitated.

In this paper we used orthogonal basis functions and expansion coefficients for inverse modeling of magnetic data. The basis functions chosen are normalized eigenvectors of second derivation of the objective function (Hessian matrix) calculate for an initial model. Limited number of basis vectors obtained in this way defines a new subspace in model parameters space. Anew objective function is defined in term of these new parameters and minimized in subspace of original space. As in geophysical inverse problems we need to inverse matrixes that are functions data and geometry of data and model parameters. The matrix inversion in new subspace of the original space will be better conditions due to less dimensionality in the inversion. Since the most significant eigenvectors corresponding the largest Eigen values in Singular Value Decomposition (SVD) of matrixes. Others eigenvectors have less influence in fitting data or lead inversion procedures to local minima. With apply subspace METHOD inversion will be fast and stable against the noise. The efficiency of the METHOD is tested with synthetic and real magnetic data (acquired from Moghan area, north-west of Iran). The results proved fast convergence and stability of inversion against the noise.

In this research, in order to investigate the effect of the piezoelectric patch which is used as a sensor or actuator in rotating flexible structures such as a helicopter blade, the free vibrations of the rotating rectangular sheet with and without the piezoelectric patch have been presented. First-order shear deformation theory is considered for plate displacement and piezoelectric field. Considering the effect of Coriolis acceleration, centrifugal acceleration and centrifugal in-plane forces, the equations of motion are derived from Hamilton's principle and the electromechanical couple equation is obtained from Maxwell's equation. For piezoelectric, two electrical conditions, open circuit and closed circuit, which are used in sensors and actuators, respectively, have been considered. The equations are discretized with the help of the numerical METHOD of generalized differential squares and the matrices of inertia mass, eccentricity, Coriolis and stiffness matrix are obtained. Natural frequency values for beam and rotating plate have been compared in Abaqus software. Also, the values obtained from the numerical solution in MATLAB have been verified with articles and ABAQUS, which have high accuracy. The effect of parameters such as hub radius, rotation speed, sheet thickness, aspect ratio, piezoelectric patch thickness and applied voltage on the natural frequency of the system has also been investigated.
