This method is based on that approach that by increasing the 1. INTRODUCTION data distance with known data, the amount of parameters effect in the unit area estimation decreases. To predict the Solar energy is one of the most valuable resources for locations that their data have not been measured and the converting to electrical energy. Due to the increasing use measured values surround the site are used. In prediction, of solar energy, it is important to determine the suitable the weight factor is determined by the distance between location for the construction.

In this regard, a lot of research has been 52 degrees and 58 minutes of longitude. Figure 1 shows done in Iran and World.

[5] In this study, a wide range of quantities, geographical, climate, economic and technical aspects has been obtained in Bushehr province in a practical way. These parameters include average annual rainfall, plant distance from city center, intercity roads and Figure 1.

Bushehr province with 23167.567 square kilometers ambit is allocated around 4.1 percent of total Iran's ambit. Dashtestan city with 6366.248 square kilometers and Kangan city with 1441.949 square kilometers respectively are the smallest and the largest city of the province . 3. CRITERIA FOR LOCATING THE SOLAR POWER PLANT In order to select the most optimal location for installing the solar plants, cultural and economic issues of area should be considered in addition to technical and Figure 4.Boolean map of the province's roads between geographical factors. In this study, parameter effects such cities as economic-environmental, socio-cultural and economic- technical has been studied. Figure 2 shows these criteria 3-1-2. Power Plant Distance from the Coastline by a diagram. Providing power plant security from risks such as tide, non-removed recreational facilities from the community, easy access to Power Plant are factors that influence to the approach in which the construction of these power plants are required to have a minimum distance of 100 meters and a maximum 3 kilometers far away from the coastline.[9] Because the province Bushehr's coastline is extended from the northeast to southeast, most of the province's parts are proper distances and are valued with number 1.

In this regard, training accelerograms selected according to the site geology of recorder station and Wavelet Packet Transform (WPT) used to decompose these records. Then Artificial Neural Networks (ANN) optimized with Ant Colony Optimization and resilient Backpropagation algorithm and learn to relate the dimension reduced response spectrum of records to their wavelet packet coefficients. Trained ANNs are capable to produce wavelet packet coefficients for a specified spectrum, so by using inverse WPT artificial accelerograms obtained.

    Somi et al. BMC Public Health (2018) 18:1266 https://doi.org/10.1186/s12889-018-6119-9 RESEARCH ARTICLE Open Access Cancer incidence in the East Azerbaijan province of Iran in 2015–2016: results of a population-based cancer registry Mohammad Hossein Somi1, Roya Dolatkhah2* , Sepideh Sepahi3, Mina Belalzadeh3, Jabraeil Sharbafi3, Leila Abdollahi3, Azin Nahvijou4, Saeed Nemati4, Reza Malekzadeh5 and Kazem Zendehdel4,6* Abstract Background: Few countries in the Middle East have a population-based cancer registry, despite a clear need for accurate cancer statistics in this region. We therefore established a registry in the East Azerbaijan province, the sixth largest province in northwestern Iran. Methods: We actively collected data from 20 counties, 62 cities, and 44 districts for the period between 20th March 2015 and 19th March 2016 (one Iranian solar year). The CanReg5 software was then used to estimate age-standardized incidence rates (ASRs) per 100,000 for all cancers and different cancer types. Results: Data for 11,536 patients were identified, but we only analyzed data for 6655 cases after removing duplicates and non-residents. The ASR for all cancers, except non-melanoma skin cancer, was 167.1 per 100,000 males and 125.7 per 100,000 females. The most common cancers in men were stomach (ASR 29.7), colorectal (ASR 18.2), bladder (ASR 17.6), prostate (ASR 17.3), and lung (ASR 15.4) cancers; in women, they were breast (ASR 31.1), colorectal (ASR 13.7), stomach (13.3), thyroid (ASR 7.8), and esophageal (ASR 7.1) cancers. Both the death certificate rate (19.5%) and the microscopic verification rate (65%) indicated that the data for the cancer registry were of reasonable quality.

In turn of the millennium, many semi-arid and arid regions of the world, including Iran are facing water problems. Shortage of water resources and the mismatch between needs and available resources, the global management of water systems has encountered serious challenges. One of the successful solutions to problems in many parts of the world, experience, participation of water users and other stakeholders in water resource management, which has become imperative. Strategies require a realistic understanding of the surrounding environment. Outside, joined the opportunities available to companies and organizations, and also in the direction they make threats. In this study, in order to derive strategies for in management of water resources, SWOT strategy formulation technique which is used by internal and external factors affecting watershed groups, mining strategy and quantitative Strategic Planning Matrix using the group selects strategies. For this reason, the weaknesses, strengths, opportunities and threats of the use of experts and experts in the field of water and a review of studies in the field and brainstorming and group decision-making and the extraction rate and rank the importance of each of the factors in evaluation matrix were determined.

    Archive of SID 1 "Gūr-e Doḵtar: Parsi Art architecture style in Dashtestan" Hamed.Sharifian History teacher of Islamic Azad University / Majlesi branch. [email protected] Abstract Most of the art lovers and specialists of art history adore Parsi artist’s skills. Considerations of the history of architecture in "Parsi" style could instruct us towards the origin of this architectural style. The ancient "Dashtestan" region was residential from the old ages and considered as one of the bases of seafaring and cruising of "Achaemenian" government in "Pars sea" ( Persian Gulf ) in Acheamenian era. Parsi style architecture works are seen a lot in this region and "Gūr-e Doḵtar" is one of those examples there have been different views stated about this exclusive building. Some people regard this building as a tomb and some others consider it as temple. Although everybody agrees on relating this building to Achaemenian era, but there are no similar views and agreements about its precise age. Consideration of the architecture of this building shows that Dashtestan was the origin of Achaemenian civilization and studying this building that belongs to one of the ancestors of "Cyrus the great" (Cyrus the great ) makes us acquainted with the transient stage of the Art architecture of "Elamid" style to "Parsi" Art architecture style. Key words: Art architecture, Parsi style, Achaemenians, Dashtestan, Gūr-e Doḵtar. www.SID.ir Archive of SID 2 Gūr-e Doḵtar: Parsi architecture 1 in Dashtestan I. Introduction There are a lot of historical indications from Achaemenian era in Dashtestan region that include over 20 various buildings, namely "Sang-siah" (Black stone) palace, "Bardak-siah" (Black Barak) palace, "Charkhab" palace, "Tappeh-ee" (Hill) palace, "Shahouie" garden , "Maze-ee Shahriari" (Royal Maze-ee) palace, "Borg" (Tower) palace, "Mill" (Minaret) palace, and some others, but Gūr-e Doḵtar is the most prominent one among them.
