3DQoE-Oriented and energy-efficient 2D plus depth based 3D video streaming over centrally controlled networks
(2018)IP networks have become the dominant platform for video delivery. However, bandwidth-hungry video is pushing networks to their limits: costs are rising for the operators and the viewing experience is not always satisfactory ... -
Application development: Fly to the clouds or stay in-house?
(2010)Cloud computing is a recent trend in IT that moves computing and data away from desktop and portable PCs into large data centers, and outsources the "applications" (hardware and software) as services over the Internet. ... -
Application of zonal pricing in Greece's electricity market
(2009)Greece's electricity market is divided in two zones, North and South, due to a generation-consumption system configuration that creates a significant transmission bottleneck from North to South. Clearly, a zonal pricing ... -
Appraisal of road pavement evaluation methods
(2019)Road pavement evaluation methods are based either on simple index of a surface characteristic, such as International Roughness Index (IRI) for roughness, Rut Depth (RD) for rutting, Sideway Force Coefficient (SFC) for ... -
Branch and price for covering shipments in a logistic distribution network with a fleet of aircraft
(2018)We consider the problem of covering a set of shipments in a logistic distribution network with a fleet of aircraft. The aim is to cover as many shipments as possible, while also minimizing the number of aircraft utilized ... -
C2M: Mobile data offloading to mesh networks
(2014)As the unprecedented growth of mobile data traffic places significant strain on cellular networks, alternative plans for exploiting already existing and under-utilized wireless infrastructure, become quite attractive. In ... -
Collaborative placement and sharing of storage resources in the Smart Grid
(2015)The development of low-cost renewable energy generators transforms households into electricity prosumers. Given that generation from renewable sources is highly volatile and does not perfectly match the daily demand pattern ... -
Collusion of operators in wireless spectrum markets
(2012)The liberalization of wireless spectrum markets has been envisioned as a method for improving mobile communication services and accommodating the increasing traffic volumes of wireless users. It has been assumed that ... -
Column generation for scheduling shipments within a supply chain network with the minimum number of vehicles
(2014)We consider the problem of scheduling a set of shipments between different nodes of a supply chain network. Each shipment has a fixed departure time, as well as an origin and a destination node, which, combined, determine ... -
Comparison of optimal buffer allocation in flow lines under installation buffer, echelon buffer, and CONWIP policies
(2020)We compare the optimal buffer allocation of a manufacturing flow line operating under three different production control policies: installation buffer (IB), echelon buffer (EB), and CONWIP (CW). IB is the conventional ... -
Control and optimization meet the smart power grid: Scheduling of power demands for optimal energy management
(2012)The smart power grid harnesses information and communication technologies to enhance reliability and enforce sensible use of energy through effective management of demand load. We envision a scenario with real-time ... -
Cost evaluation of noise barriers implementation in the Greek highway network
(2016)Transportation side effects like, noise, accidents and air pollution and others are a cost that arises from an economic transaction and that falls on people who do not participate in the transaction. Among those side ... -
Critical review of pricing schemes in markets with non-convex costs
(2016)We consider a market in which suppliers with asymmetric capacities and asymmetric marginal and fixed costs compete to satisfy a deterministic and inelastic demand of a commodity in a single period. The suppliers bid their ... -
Day-ahead electricity price forecasting using optimized multiple-regression of relevance vector machines
(2012)In deregulated, auction-based, electricity markets price forecasting is an essential participant tool for developing bidding strategies. In this paper, a day-ahead intelligent forecasting method for electricity prices is ... -
Determining a Socially Fair Drinking Water Pricing Policy: The Case of Kozani, Greece
(2016)The Water Framework Directive (WFD) 2000/60/EC clearly indicates that all member states should develop and apply water pricing policies to recover the Full Water Cost (FWC) (including the direct cost, the environmental and ... -
Developing a methodology towards full water cost recovery in urban water pipe networks, based on the "user-pays" principle
(2014)In the present paper, using an urban water supply and distribution system as a case study (city of Kozani, Greece), the components of the full water cost (direct-DC; environmental-EC; resource-RC) are analysed, introducing ... -
A Dynamic Pricing and Leasing Module for 5G Networks
(2020)In this paper, a novel framework for enabling dynamic Policy and Charging Rules in modern 5G multi-tenancy environments is designed and presented. More specifically, adaptive pricing schemes are utilized by MNOs for ... -
Dynamic RAT Selection and Pricing for Efficient Traffic Allocation in 5G HetNets
(2019)In this paper, we focus on 5G heterogeneous networks, considering the existence of multiple Distributed Units (DUs) that can provide access to end users implementing several access technologies, managed by a Central Unit ... -
Dynamic virtual machine allocation in cloud server facility systems with renewable energy sources
(2013)This paper explores the problem of virtual machine (VM) allocation in a network of cloud server facilities which are deployed in different geographical areas. Each cloud server facility is connected to the conventional ... -
An eco-efficient and economical optimum evaluation technique for the forest road networks: the case of the mountainous forest of Metsovo, Greece
(2018)The sustainable forest management can be achieved only through environmentally sound and economically efficient and feasible forest road networks and transportation systems that can potentially improve the multi-functional ...
