Light rail systems are sustainable, energy-efficient, and eco-friendly alternatives to public transport that can offer solutions increasing traffic density. As a solution congestion, Akcaray, the first transportation light system in Kocaeli, was launched by Ulasımpark Kocaeli 2017. In this study, operational efficiency service level performance of 12 trams belonging 4 bus lines interact with Ak...

The objective of this paper is to propose a method for evaluating the eco-efficiency business organizations. In order adequately capture inherent properties eco-efficiency, we present decision support model that can evaluate an organization based on ranking derived efficiencies at operational, energy, and environmental dimensions taking these factors into account comprehensively. proposed was d...

Home area energy networks will be an essential part of the future Energy Internet in terms of energy saving, demand-side management and stability improvement of the distribution network, while an energy router will be the perfect choice to serve as an intelligent and multi-functional energy interface between the home area energy network and power grid. This paper elaborates on the design, analy...

Wave energy has a promising technical potential that could contribute to the future energy mix. However, costs related to the deployment of wave energy converters (WECs) are still high compared to other technologies. In order to reduce these costs, two principle options are available, a reduction in cost and an increase in productivity. This paper presents a reliability-based computational tool...

Data centers are becoming increasingly popular for the provisioning of computing resources. The cost and operational expenses of data centers have skyrocketed with the increase in computing capacity [1]. Energy consumption is a growing concern for data center operators. It is becoming one of the main entries on a data center operational expenses (OPEX) bill [2,3]. The Gartner Group estimates en...

'What's the use of a fine house if you haven't got a tolerable planet to put it on?' i Summary The building and real estate sectors are responsible for a significant portion of global society's overall environmental impacts. This thesis considers three actions that need to be applied in the sectors to mitigate these impacts. Firstly, all new buildings need to be constructed for very low operati...

Traditional Automatic Train Operation (ATO) algorithms are generally designed based on single-train operation with the objective of improving the speed profile of a single train to reduce mechanical energy consumed under operational constraints. For many electrified rail transit systems where energy cost is calculated at the substation level, minimizing energy consumption needs to consider the ...
