Acar, Ramazan; Saplioglu, Kemal
It isimportant to detect sediment load truly in the project process of water structures such as both dam and regulator to determine pollution level, to use and to supply potable water. In this work, methods such as Adaptive Neuro Fuzzy Interference Systems (ANFIS), Artificial Neural Networks (ANN) and Multiple Linear Regression (MLR) are experienced for three Flow Observation Stations on Fırat Basin. K-Means Clustering Algorithm is used to select Clustering numbers of ANFIS Models being formed. Sediment (Qs), Precipitation (P), Flow rate (Q) and temperature (P) data from each station are used in this study. Sediment estimation model is developed for each station by using the data. The value of the day when precipitation occurs (P), the value of the day before precipitation occurs (P-1), flow and temperature rates are used as input factors; sediment concentration is used as output factors. The model being formed is compared for all of the stations with regard to regression coefficient (R2 ) and mean percentage error (MPE) in both education and test stages. As a consequence of the analysis, subset numbers of ANFIS model being formed by determining subset of K-Means Clustering Algorithm has more successful results instead of ANFIS Models being randomly formed. It is also observed that the Models of ANFIS and ANN methods have closer results to the values being observed when they are compared to MLR methods.

Yalçın, Erkut; Furtana, Beyza; Kök, Baha Vural; Yılmaz, Mehmet
The wear layer, which is used in the top layer of flexible pavements and is subjected to the most stress, is produced mostly with modified binders due to increased traffic volume and loads. Modification of the wear layer with polymer type additives has become inevitable. Recently bitumen used in bituminous mixture is modified with styrene-butadiene-styrene (SBS) polymer. There are quite successful applications in this regard. However, demand for SBS makes it difficult to provide always and brings on the use of alternative additives. In this study, the effect of ethylene-vinyl-acetate (EVA) based resin (EBR) on the rheological properties of bituminous binder was investigated and compared with SBS modification. As a result, it was found that 4% EBR modification in terms of rutting and cohesion properties showed similar performance with 3% SBS modification and in the case of the evaluation of low and high temperature properties together, 4.7% EBR modification had similar performance with 3% SBS modification.

Aksoy, Suha; Icen, Abdullah
In this study, the depth of the improvement which will be made under a foundation which lies on soft soil is investigated experimentally. If the characteristics of the soil on which a building will be constructed are not sufficient to bear the loads coming from that building, then the ground is improved. Jet grout It is one of the soil improvement methods and is frequently applied in our country. When stabilizing the soil, improvement should generally be made to the underlying stiff soil layer. However, in cases where the solid ground layer is deep, the depth to which the improvement is to be made depends solely on the assumptions made for the solids calculated from the elasticity theory. According to these theories, which consider the ground as elastic and incompressible, the stresses on the subsoil soils are effective up to a depth of 1,5-2,0 times the width (B) of the foundation. Since soil improvement is a costly process, engineers do not make improvements to these depths. In this study, the bearing capacity of the foundations which are improved at different depths was determined experimentally. In order to model the soft soils and foundations in terms of bearing capacity, a continuous steel model foundation resting on loose and medium-firm sandy ground was used. The improved soil under the continuous foundation was modeled by using concrete blocks and experimental results were obtained. It was determined that the superficial improvement to be made on loose soils with insufficient bearing capacity had no significant effect on bearing capacity. However, as the depth of improvement increases, the increase in bearing capacity increases to a

- MakaleAçık Erişim2020Tuncelı report of major ragıp gümüşpala (1936-1937)
Zengin, Ersoy
Ragıp Gümüşpala was born in Edirne in 1897. Ragıp Gümüşpala, who graduated from the Military Academy in 1916, fought on various war fronts during the First World War. Towards the end of the war, he was captured by the English. After living a life of captivity for a while in Egypt, he came to Turkey and joined the National Struggle. After the proclamation of the republic, he participated in the operations to suppress the rebellions of Sheikh Said (1925) and Koçuşağı (1926). After carrying out various duties, he became an intelligence officer of Tunceli governorate and command post between 1936 and 1938. He is known to have fallen captive to the rebels during operations to suppress the rebellion. After the 27 May 1960 coup, Ragıp Gümüşpala became the Chief of General Staff. He carried out this duty for a short period and retired in the same year. He founded Adalet Partisi (Justice Party) in 1961 and became a member of parliament of Izmir. Major Ragıp Gümüşpala recorded his observations and analyses on the people of Dersim as a report. Gümüşpala, who examines the people of Dersim in terms of their race, religion, sect and traditions, put forward some striking arguments. Gümüşpala reports that Tunceli Act went into effect in 1935 and the juridical and administrative staff took the office after Elaziz was established as the center of Tunceli Province. He expresses how the Republic’s government would make the region prosperous by road, bridge and school projects and what projects would be implemented in order to save the people of the region from poverty. Gümüşpala underlines the necessary precautions, presenting the elements distinguishing the Alawite and Sunni people. He manifested how the Qizilbashs moved away from the Sunni Turkish society; the sayyids and dedes misled the Qizilbashs; muftis and hodjas misled the Sunnis; how the religious authorities disconnected these two societies. He touched upon the influence of Christianity on the belief and culture of the Qizilbashs. He reports that the Armenians built church-like buildings in the regions deemed as sacred by the Qizilbashes and made them kiss a piece of bone that they put in the middle of a cross, claiming that it was the finger of His Holiness Ali. He reports that the pilgrim sites of the Qizilbashs were also used by the Armenians during the Ottoman period; and both of the races worshipped in the same location. Gümüşpala grounds the reason of the Qizilbash’s residence in Dersim, a geography where living conditions are hard, on the Sect Wars between Selim I and Ismail I in the 16th century. He states that the Qizilbashs found a space for living in Dersim having a rough terrain as a result of the politics of suppression inflicted on them by Selim I. Gümüşpala, who believed that the Qizilbash of Dersim had Turkish origins, tried to explain this argument through elements of language and culture. That the villages, clans, places and persons were referred with their Turkish names, that the sentence structures they used were compatible with Turkish syntax, that the tombstones were made of sculptures of ram, that their folk songs and tunes were the same as those of the Turks in the Central Anatolia were given as proofs of this thesis. He thinks that Turkish language of the region differs because the people of Dersim married Persian and Zaza people during their migration from Khorasan to Anatolia. He thinks that a distorted version of the Turkish language, that is a mixture of Turkish and Persian, took shape as a result of these marriages. He argues that the Qizilbashs of Dersim have sacred spaces in the mountains and in the forests because of the Shamanist tradition which the Turks had previously as belief. He claims that the name of Şamuşağı clan, located in Ovacık, was derived from Shaman/Shamo uşağı. Furthermore, that the dedes had the ability of prophecy is attributed to the Shaman belief. In his report, Gümüşpala argues that the influence and authority of the state can be realized in the region if the influence of sayyids and landlords decreases. Although certain parts of the report were previously published, the report which will be published contains much new information that can contribute to Turkey’s recent history.

Mountain goats, which we encounter with their divine features in mythological times, have been the subject of folklore, belief, art, architecture in various meanings until today. Mountain goats, which are also seen in Tunceli folklore and beliefs, are accepted as sacred and blessed creatures among the people in the region. Although they roam in flocks in the Tunceli mountains, there is a belief among the local people that these creatures were not abandoned. These creatures, which are accepted as sacred by the people, are accepted as the symbol of Hızır with their fast and agile nature, and they are also accepted as sacred personalities such as Ana Fatma and Düzgün Baba. The belief that the people who hunt them will face adverse events that cannot be compensated, as it is considered as one of the biggest sins to hunt and harm these creatures, which are associated with people who are considered sacred in the belief of the Tunceli Alevi.
