Due to the energy- and carbon-intensive characteristics, the transportation sector became a potential field for GHG emission mitigation researches. In Turkey, transportation sector has been responsible for the 16% of total GHG emissions (excluding LULUCF) and 22.6% of total fuel combustion emissions in 2015 due to rapid motorization and VKT increase rates in the last two decades. These high values are also parallel with the modal share distribution in Turkey, as road transportation is the dominant system in both passenger and freight transportation and caused almost 90% emission shares. However, the transportation sector has many options to reduce emissions. In this study, GHG emission reduction potentials of mitigation actions are analyzed through technology choices and fuel substitutions using TIMES model that is a national level, bottom-up, and piece-wise linear representation of the Turkish transportation network. First, the baseline scenario constructed using TIMES model and then a set of GHG mitigation measures were adopted and analyzed separately for the emission reduction potentials and cost evaluations. The selected mitigation actions were; expanding intermodal/combined transport in intercity passenger transport, expanding electric vehicles in public transport, increasing the share of public transit in urban transport, expanding the usage of bicycle in urban transport, increasing the efficiency of fuel consumption, increasing the usage of alternative fuels (bioethanol, biogasoline, biodiesel, etc.), shifting freight transport from road dominancy to intermodal/combined transport.The results of the quantitative comparison of selected mitigation actions showed that EV penetration up to 20% had the highest mitigation rate and the highest mitigation cost. The interesting finding was the emission reduction potential and low cost of increasing bicycle usage with the bike network connections to the urban rail system in major cities having existing and/or planned urban rail projects. Considering the average emission mitigation cost, the implementation of metro lines to metropolitan cities starting from 2025 was found as the best mitigation action among others.

Thermo-resistant green microalgae for effective biodiesel production: Isolation and characterization of unialgal species from geothermal flora of Central Anatolia
Onay, Melih; Sonmez, Cagla; Öktem, Hüseyin Avni; Yücel, Ayşe Meral (2014-10-01)
Oil content and composition, biomass productivity and adaptability to different growth conditions are important parameters in selecting a suitable microalgal strain for biodiesel production. Here, we describe isolation and characterization of three green microalgal species from geothermal flora of Central Anatolia. All three isolates, namely, Scenedesmus sp. METUNERGY1402 (Scenedesmus sp. ME02), Hindakia tetrachotoma METUNERGY1403 (H. tetrachotoma ME03) and Micractinium sp. METUNERGY1405 (Micractinium sp. M...
Sustainable development of energy, water and environment systems index for Southeast European cities
Kılkış, Şiir (2016-09-01)
Benchmarking the performance of cities across aspects that relate to the sustainable development of energy, water and environment systems requires an integrated approach. This paper benchmarks a sample of 12 Southeast European cities based on a composite indicator that consists of 7 dimensions and 35 main indicators. The composite indicator is namely the Sustainable Development of Energy, Water and Environment Systems (SDEWES) City Sustainability Index. The first three dimensions are energy consumption and ...
Modelling the Dynamic Response of Pile Foundations in Performance Based Geotechnical Engineering Framework
Unutmaz, Berna; Gülerce, Zeynep (2016-06-26)
The objective of this study is to develop a performance-based earthquake engineering (PBEE) framework for the soil liquefaction-related hazards and estimate the levels of exceeding liquefaction related engineering demand parameters (EDPs) in a probabilistic manner. The post-cyclic lateral deformation at the pile head (x) is tried to be predicted from ground motion intensity measures (IMs) such as peak ground acceleration (PGA) and Arias Intensity (I a). Within this scope, a number of finite difference anal...

Satellite and in situ data are utilized to investigate the mesoscale dynamics of the Black Sea boundary current system with special emphasis on aspects of transport and productivity. The satellite data are especially helpful in capturing rapid sub-mesoscale motions insufficiently resolved by the in situ measurements.
Thermodynamic and thermoeconomic comparison of combined cycle cogeneration systems
Colpan, Can O.; Yesin, Tulay (2006-01-01)
In this paper, several configurations of combined cycle cogeneration systems are investigated by energy, exergy and thermoeconomic analyses. In each of these configurations, varying steam demand is considered rather than fixed steam demand. Among the different approaches for thermoeconomic analysis in the literature, the specific exergy costing method is applied. Since the systems have more than one product (process steam and electrical power), systems are divided into several sub-systems and cost balances ...
