In this study,the influence of Canal Istanbul on salinity distribution in the northern Marmara Sea is investigated using a previously calibrated 3 D hydrodynamic and salinity model. Moreover, the salinity field of the canal and its propagation are examined based on various meteorological cases. Finally, the flow structure of the canal is determined. It is calculated that at the southern end of the canal, mainly unidirectional flow(from the Black Sea to the Marmara Sea)occurs during 68% of the simulation period. A two-layer flow is seen only 28% of the time with a weak lower layer flow, whereas this value decreases to 4% at the north end of the canal. In the southward direction(to the Marmara Sea), velocities higher than 1.5 m/s are rarely observed along the canal. The average surface salinity difference in the northern Marmara Sea due to the construction of the canal is calculated to be smaller than 0.50 ppt. The salinity difference gradually diminishes as water depth increases and after 25 m(from the surface) almost no difference is observed.展开更多

In life story narratives, these three examples give us information about the history, economic linkage, and life styles of neighboring families. The first category basically consists of the families that live in the area for a very long time, over some decades or more. Even one of them mentioned that, their family is living there for hundreds of years. The second category, which represents the biggest group living in the area, consists of families migrated from Sivas, a central Anatolian city, in the 1950s. Third category consist of Kurds migrated from eastern Anatolian villages and cities such as Mardin. Each category has different kinds of nostalgia about the past. Interviewees from the first category talk about family narratives related to the small village Merdivenk6y, Fikirtepe and the area. Mostly, they have a story of a "well off" family, structured and detailed narratives about the family history, including relations with the Ottoman Palace such as doing some sort of production for it. They seem very sensitive about the local cultural characteristics and what's going on in the area; realistic about and reconciled with what will happen as a result of slum clearance. Interviewees from the second category mostly emphasize the hardship of settling in a muddy suburban area, where once "muddy lands" now turned out to become valuable urban properties on which new and modem neighborhoods, shopping malls and office buildings will be built. They are expecting to get maximum gain out of the exchange of their small property, since they are desperately in need, because of the financial crisis situation. Although their houses with small gardens near the small industrial area are small, old, and neglected for years, they expect the most. Relatively newcomers, Kurdish people in the area talk about the good old days on the one hand and the painful stories about migration and settling on the other hand. They do not think about going back to their native lands, since here it is easier for them to find jobs in the informal economy as they live very close to central parts of the city. As a part of a larger research study focused on the experience of urban transformation, we made more than 50 interviews, trying to make a general outlook of the area, working on the dynamics of change before and after the urban transformation that had been started in June 2010. By using oral history research techniques and social science methodology, we conducted in-depth interviews with the people living in the neighborhood, made observations in the neighborhood and took photographs. The author's work is about the reflections of nostalgia in their family histories and experiences of different categories of families living in the area referring life story narratives. As far as the author can see in each group he works on, there are different contradictions related to their position in the city and conception of the area. The urban transformation presented and is perceived as a fortune for all of them, but it will have contradictory outcomes in reality for each as indicated in other examples in the world.展开更多

In this study, the aim was to evaluate the results of regular measurements of air pollutants PM10 (Particulate Matter of 10 Microns in Diameter) and SO2 (Sulfur Dioxide) concentrations in the city of Istanbul by taking the years 2013 and 2015 as a sample. The data were obtained through the website http://www.havaizleme.gov.tr, which was published by the Administration of Marmara Clean Air Center of Ministry of Environment and Urbanization in Turkey. For the years 2013 and 2015, the mean SO2 concentration was 8.35 ± 6.04 and 10.60 ±7.16 μg/m^3. The mean PMI0 concentration was 73.06 ± 30.63 μg/m^3 for 2013 and 51.57 ± 18.84μg/m^3 for 2015. The acceptable upper limit values by WHO (World Health Organization) for daily mean SO2 and PMI0 concentrations respectively are 20 μg/m^3 and 50μg/m^3. In Istanbul, SO2 concentrations were above the upper limit values recommended by WHO, but PM10 concentrations during 2013 and 2015 were over the recommended limit values by WHO. As the particulate matter pollution is at high concentrations during these two years, it has shown that air pollution emerges as a problem awaiting solutions in Istanbul, where is industrially intense, highly populated and also with high traffic density.展开更多

Within this context, the relative efficiency measurement and statistical (parametric) efficiency measurements that employ (non-parametric) mathematical programming based on Data Envelopment Analysis (DEA) method are such instruments and they are used to determine brand value and financial performance that are pivotal factors in company mergers, acquisitions, and joint venture activities. This study works with Turkish banks whose brand values have been calculated by Brand Finance and whose brand values have been listed in Global Banking 500 for the years between 2010 and 2012. Firstly, using the banks' data published by Public Disclosure Platform (PDP/KAP), a non-parametric model with three inputs and four outputs has been developed. Relative and super efficiencies of the banks have been measured by mathematical programming based DEA and the efficiency scores that come out of this analysis have been ranked, resulting in an "efficiency ranking of the banks". Following this, the efficiency ranking of these banks has been compared with brand value ranking of Brand Finance and their similarity/correspondence has been assessed.展开更多

Promotion of a strong internal audit function plays a key role in assisting the board to discharge its governance responsibilities. The internal audit needs to exert its important function for refining corporate governance procedures, improving internal control, and strengthening risk management. The rules concerning internal auditing issued by the Banking Regulation and Supervision Agency, Capital Markets Board of Turkey, and other public societies have contributed to the development of internal auditing in Turkey. The Capital Markets Board of Turkey published “Communiqu6 Serial: IV, Noi 56 on Identification and Application of Corporate Governance Principles” (Official Gazette dated December 30, 2011, No. 28158). In Part 4.2.4 of these principles, it was stated that “The board of directors supervise the efficiency of risk management and internal control systems at least once a year. Information about existence, operation, and efficiency of internal control and internal audit is given by annual report”. The objective of this study is to analyze the structure of internal audit function-related information on the annual reports of companies that are included in the Borsa Istanbul. Annual reports of 192 manufacturing companies listed on Borsa Istanbul were examined by content analysis method.展开更多

In the analyses the daily precipitation and temperature data sets of Florya and Goztepe Meteorological Stations which have similar locational features were used. These sets were recorded between 1960 and 2013 (for 54 years). In order to emphasize the differentiations in the last 15 years the analyses were conducted comparatively both for the 15-year and for the 54-year periods and then the results were evaluated. The changes in the monthly, annual and seasonal quantity, type and frequency of the precipitation in the form of rain and the features of the temperature’s monthly, annual and seasonal changes, the De Martonne aridity index and the Thornthwaite climate classification were carried out. The results showed that during the years from 1999 to 2013 the climate type of Istanbul changed from semi-humid climate to arid and less-humid climate. Most notably the precipitation during the warm periods has decreased, but the frequency of the intense rain has increased and the majority of these episodes of intense rain coincided with the warm periods. Other determinations were the rise in the annual average temperature and the extension of the warm periods in a year. This differentiation of the temperature features can lead to the aggravation of the evaporation and it can be effective for a longer period during the year. Being aware of this differentiation in the features of precipitation and temperature and taking these data into consideration in all sorts of planning and managing strategies have a special importance for the 14 million or more people living in Istanbul.展开更多

The objective of this study was to determine changes in land use in the Black Sea coastal regions of Jstanbul between 1987 and 2007. Landsat 30 m satellite images from 1987 and 2007 are used in the study. The study area is 1000 m in width from the coastline to the land and the study has been carried out using the controlled classification method to classify areas into residential, agricultural, forest, bare land, brush/grassland, and lake/pond land classes. Land use changes between 1987 and 2007 were analysed in detail. Residential areas of the Black Sea coastal regions of istanbul increased by 122% over the two decades. Also an increase of 55% in agriculture areas was observed, while there were decreases of 26% in forest areas and 15% in free land. A 21% increase in the area of brush and grassland took place. Furthermore 79% of the study area was covered by residential areas in 2007. It is probable that pressure on the Jstanbul coastal regions will continue due to migraton and rapid urbanization. Therefore, Istanbul's Black Sea coastal regions should be maintained using a sustainable coastal management plan.展开更多

In this study, to assess tunnels in construction and operation phases, the matrix method, through which the “Impacting Factors” and “Environmental Components” are determined, is also outlined. The affected environment was divided into thirteen components, such as Ecology, Surface water, Air quality, etc. In this paper, matrix method was applied to evaluate the impact of tunneling in three typical tunnels and compare them with standard diagrams of Environmental Components that were derived and introduced. These tunnels were: Urban Utility tunnel in Tehran, Eurasia tunnel in Istanbul and Tsuen Wan drainage tunnel in Hong Kong. Based on the acquired results, the present paper finally concluded that among three cases, Tsuen Wan drainage tunnel affects the environment in construction phase more than others, while Eurasia tunnel effects on air quality are more significant in operation phase.展开更多

Travel time, being spatial in nature, requires spatial sensors to measure it accurately. Bluetooth is emerging as a promising technology for the direct measurement of travel time, and is reported in a few studies from homogenous traffic conditions. At the same time, there have been no studies on the applicability of Bluetooth for travel time estimation in heterogeneous traffic seen in Istanbul and even that Turkey. Bluetooth data collected from a busy urban road in Istanbul city have been analyzed and the penetration rate was found to be about 5 %. Two wheelers and light motor vehicles have been detected using the Bluetooth sensor and the data have been extrapolated to estimate travel times of other classes of vehicles. The study developed linear relationships between speeds of different classes of vehicles through weighted linear regression methods and were used for the estimation of stream travel time. The results obtained were promising and show that Bluetooth is a cost-effective technology for estimation of travel time for heterogeneous traffic conditions.展开更多

文摘Air pollution has been the most important health issue in recent years. In this study, the aim was to evaluate the results of regular measurements of air pollutants PM10 (Particulate Matter of 10 Microns in Diameter) and SO2 (Sulfur Dioxide) concentrations in the city of Istanbul by taking the years 2013 and 2015 as a sample. The data were obtained through the website http://www.havaizleme.gov.tr, which was published by the Administration of Marmara Clean Air Center of Ministry of Environment and Urbanization in Turkey. For the years 2013 and 2015, the mean SO2 concentration was 8.35 ± 6.04 and 10.60 ±7.16 μg/m^3. The mean PMI0 concentration was 73.06 ± 30.63 μg/m^3 for 2013 and 51.57 ± 18.84μg/m^3 for 2015. The acceptable upper limit values by WHO (World Health Organization) for daily mean SO2 and PMI0 concentrations respectively are 20 μg/m^3 and 50μg/m^3. In Istanbul, SO2 concentrations were above the upper limit values recommended by WHO, but PM10 concentrations during 2013 and 2015 were over the recommended limit values by WHO. As the particulate matter pollution is at high concentrations during these two years, it has shown that air pollution emerges as a problem awaiting solutions in Istanbul, where is industrially intense, highly populated and also with high traffic density.

文摘In this study, the changes in the data of Istanbul’s precipitation and temperature and the features of these changes were analyzed by different methods. In the analyses the daily precipitation and temperature data sets of Florya and Goztepe Meteorological Stations which have similar locational features were used. These sets were recorded between 1960 and 2013 (for 54 years). In order to emphasize the differentiations in the last 15 years the analyses were conducted comparatively both for the 15-year and for the 54-year periods and then the results were evaluated. The changes in the monthly, annual and seasonal quantity, type and frequency of the precipitation in the form of rain and the features of the temperature’s monthly, annual and seasonal changes, the De Martonne aridity index and the Thornthwaite climate classification were carried out. The results showed that during the years from 1999 to 2013 the climate type of Istanbul changed from semi-humid climate to arid and less-humid climate. Most notably the precipitation during the warm periods has decreased, but the frequency of the intense rain has increased and the majority of these episodes of intense rain coincided with the warm periods.

文摘In this study,the hourly directions of eight banking stocks in Borsa Istanbul were predicted using linear-based,deep-learning(LSTM)and ensemble learning(Light-GBM)models.These models were trained with four different feature sets and their performances were evaluated in terms of accuracy and F-measure metrics.While the first experiments directly used the own stock features as the model inputs,the second experiments utilized reduced stock features through Variational AutoEncoders(VAE).In the last experiments,in order to grasp the effects of the other banking stocks on individual stock performance,the features belonging to other stocks were also given as inputs to our models.While combining other stock features was done for both own(named as allstock_own)and VAE-reduced(named as allstock_VAE)stock features,the expanded dimensions of the feature sets were reduced by Recursive Feature Elimination.As the highest success rate increased up to 0.685 with allstock_own and LSTM with attention model,the combination of allstock_VAE and LSTM with the attention model obtained an accuracy rate of 0.675.Although the classification results achieved with both feature types was close,allstock_VAE achieved these results using nearly 16.67%less features compared to allstock_own.When all experimental results were examined,it was found out that the models trained with allstock_own and allstock_VAE achieved higher accuracy rates than those using individual stock features.It was also concluded that the results obtained with the VAE-reduced stock features were similar to those obtained by own stock features.
文摘Travel time estimation is an integral part of Intelligent Transportation Systems, and has been an important component in traffic management and operations for many years. Travel time, being spatial in nature, requires spatial sensors to measure it accurately. Bluetooth is emerging as a promising technology for the direct measurement of travel time, and is reported in a few studies from homogenous traffic conditions. At the same time, there have been no studies on the applicability of Bluetooth for travel time estimation in heterogeneous traffic seen in Istanbul and even that Turkey. Bluetooth data collected from a busy urban road in Istanbul city have been analyzed and the penetration rate was found to be about 5 %. Two wheelers and light motor vehicles have been detected using the Bluetooth sensor and the data have been extrapolated to estimate travel times of other classes of vehicles. The study developed linear relationships between speeds of different classes of vehicles through weighted linear regression methods and were used for the estimation of stream travel time. The results obtained were promising and show that Bluetooth is a cost-effective technology for estimation of travel time for heterogeneous traffic conditions.
文摘The aim of the present study was monitoring ofAspergillus spp. in six different hospitals in |stanbul. The authors know that disease like aspergillosis illness caused by Aspergillus spp. is very dangerous for people's health. Therefore, the present work has been performed to evaluate the hospitals' environment. Petri-plate method has been performed for isolation. Samples were taken at six different hospitals and various locations of each. 13 different Aspergillus species and 141 Aspergillus colonies have been isolated in totally. Maximally isolated species are: Aspergillus niger (29.1%). A. nidulans (21.3%), A. candidus (12.8%), A. ochraceus (9.2%), and A. versicolor (7.8%). A. fumigates, A. flavus are the most pathogen species in human which have been isolated minimally.
