Measuring Sustainability Efficiency Using a Two-Stage Data Envelopment Analysis Approach
(2016)In this article, we apply an additive two-stage data envelopment analysis estimator on a panel of 20 countries with advanced economies for the time period 1990–2011 in order to create a composite sustainability efficiency ... -
Measuring the Effect of Economic Growth on Countries’ Environmental Efficiency: A Conditional Directional Distance Function Approach
(2017)Using a recently developed probabilistic approach of a conditional directional distance function, we measure the effect of economic growth on countries’ environmental efficiency in carbon dioxide emissions for a sample of ... -
Minimum distance efficiency measure in bank production: A directional slack inefficiency approach
(2022)In the non-radial efficiency measurement literature, it is common to estimate technical (in)efficiency by maximising weighted slacks primarily from the computational viewpoint. This means that efficiency measures and targets ... -
Modelling a multi-period production process: Evidence from the Japanese regional banks
(2021)This paper applies the additive relational network DEA model to examine the multi-period efficiency and productivity of Regional Banks I and II in Japan between 2002 and 2017. The examined timeframe covers two turbulent ... -
On evaluating the impact of tile partitioning in AV1
(2018)The advent of 4K and 8K resolutions in cameras and TV sets, posed a challenge to Video on Demand (VoD) and live streaming industry since the network overhead compared to FullHD was multiplied. For this reason, new video ... -
Parallelised Multithreaded Applications on a 4-core Field Programmable Gate Array (FPGA) Architecture
(2022)Background: The challenges in real-time multithreading, particularly in the efficiency of multithreaded applications running concurrently on multiple cores, have evolved significantly due to the increase in IoT, cloud and ... -
Parametric optimization of material extrusion 3D printing process: an assessment of Box-Behnken vs. full-factorial experimental approach
(2022)This work investigates the efficiency of the Box-Behnken design (BBD) in contrast with the full-factorial design (FFD) in ultimate tensile strength (UTS) of PA12 material extrusion 3D printing (ME-3DP) specimens. Three ... -
Predicting operational and environmental efficiency of primary sectors of EU countries, by implementing Artificial Neural Networks
(2017)One of the most important policy reforms for the European Union (EU) agriculture was the implementation of the Agenda 2000, which establishes a new framework for subsidies management, decoupled from both crop and animal ... -
Productivity growth in network models: An application to banking during the financial crisis
(2019)We construct Malmquist Productivity indices for two-stage processes. A two-stage data envelopment analysis model with an additive efficiency decomposition is used for the modelling of the two-stage process. We incorporate ... -
Ranking eu agricultural sectors under the prism of alternative widths on window dea
(2021)Providing food security while preserving natural resources and reducing the use of production factors (land, labor, and capital), is a critical challenge for EU agricultural sectors in the 21st century. Sustainable Development ... -
Recuperators investigation for high temperature supercritical carbon dioxide power generation cycles
(2017)Supercritical carbon dioxide (s-CO2) Brayton cycles are a promising technology for the next generation power conversion cycles, attaining equivalent or higher cycle efficiency compared to conventional power cycles at similar ... -
Research and development spending and technical efficiency: evidence from biotechnology and pharmaceutical sector
(2020)Set within the expenditure context of the global financial crisis (GFC), this paper explores how the research and development (R&D) expenditures of biotechnology and pharmaceutical companies affect their technical efficiency ... -
Route efficiency index as an operational tool for detour decision making in an urban motorway
(2018)Decisions on efficient detours are crucial for motorway operations following closures. This paper presents a framework for supporting decision making on detour routing in urban motorways. A Route Efficiency Index (REI) is ... -
Spectral Reflectance Indices as a High Throughput Selection Tool in a Sesame Breeding Scheme
(2022)On-farm genotype screening is at the core of every breeding scheme, but it comes with a high cost and often high degree of uncertainty. Phenomics is a new approach by plant breeders, who use optical sensors for accurate ... -
Thermodynamic modeling and comparative analysis of supercritical carbon dioxide Brayton cycle
(2017)Supercritical CO2 cycles is a promising technology for the next generation power conversion cycles. Supercritical CO2 Brayton cycles offer equivalent or higher cycle efficiency when compared with steam cycles at similar ... -
Tile Based Wavefront Parallelism in HEVC
(2020)High Efficiency Video Coding (HEVC) was developed to tackle the 4K resolution era, achieving up to 50% more compression efficiency (for the same video quality) compared to its predecessor H.264/AVC. However, this performance ... -
User cooperation in heterogeneous cellular networks for improved spectral efficiency
(2015)In this paper we propose user cooperation in Heterogenous cellular networks (HCNs) for combating intra-cell interference and improving downlink spectral efficiency (SE). The main idea we put forward is to employ interference ... -
