Key parameters controlling surface quality and dimensional accuracy: a critical review of FFF process
(2022)Fused filament fabrication (FFF) is an additive manufacturing process, which constructs physical items by fused melt material, selectively deposited layer-by-layer through a heated extrusion mechanism. Parameters’ selection ... -
Long-term storage of onion and the factors that affect its quality: A critical review
(2017)Storage of onions is a multifaceted issue, which involves many preharvest and postharvest factors. One of the major factors that affect onion storage is the selection of the proper cultivar, since there are significant ... -
“On-Line” Heating Emissions Based on WRF Meteorology— Application and Evaluation of a Modeling System over Greece
(2022)The main objective of the present study is the development of an “on-line” heating emissions modeling system based on simulated meteorological data and its integration with air quality modeling systems in order to improve ... -
PLOT: Privacy in location based services: An open-ended toolbox
(2009)The widespread adoption of Location Based Services (LBSs) coupled with recent advances in location tracking technologies, pose serious concerns to user privacy. As a consequence, privacy preserving approaches have been ... -
Policy conflict analysis for DiffServ quality of service management
(2009)Policy-based management provides the ability to (re-)configure differentiated services networks so that desired Quality of Service (QoS) goals are achieved. This requires implementing network provisioning decisions, ... -
Quality Factors of Commercial Snail Fillets as Affected by Species
(2022)Research background. This study fulfils a need for investigation of a quality profile of snail fillets. Edible snails are a famous food product consumed worldwide and treated as delicacy. Nutritional value, colour and ... -
Real time measurements for quality control of industrial rod manufacturing
(2016)This work proposes a fully automated approach for vision-based quality control of manufactured metal rods. The proposed approach is able to detect the features of the rod (holes) and calculate the curvature of the object ... -
Real time vision-based measurements for quality control of industrial rods on a moving conveyor
(2018)This work proposes a fully automated approach for vision-based quality control of manufactured metal rods. The proposed approach is able to detect the main axis of the rod and calculate its curvature, versus specifications. ... -
Reputation-assisted utility maximization algorithms for peer-to-peer networks
(2008)Peer-to-peer networks are voluntary resource sharing systems among rational agents that are resource providers and consumers. While altruistic resource sharing is necessary for efficient operation, this can only be imposed ... -
The Role of Auditing, Food Safety, and Food Quality Standards in the Food Industry: A Review
(2017)Food safety and quality audits are used widely in the food industry for various reasons (to evaluate management systems, obtain certifications to certain food safety and quality standards, assess the condition of premises ... -
Run Rules-Based EWMA Charts for Efficient Monitoring of Profile Parameters
(2021)In usual quality control methods, the quality of a process or product is evaluated by monitoring one or more quality characteristics using their corresponding distributions. However, when the quality characteristic is ... -
Scheduling policies for heterogeneous, approximate computing systems
(2017)Energy consumption is a primary concern for modern computer systems. Conservative approaches, such as DVFS, which have been used in the past to optimize the performance / power tradeoff have reached their limits. Heterogeneity ... -
Significance-aware program execution on unreliable hardware
(2017)This article introduces a significance-centric programming model and runtime support that sets the supply voltage in a multicore CPU to sub-nominal values to reduce the energy footprint and provide mechanisms to control ... -
A significance-driven programming framework for energy-constrained approximate computing
(2015)Approximate execution is a viable technique for energy-constrained environments, provided that applications have the mechanisms to produce outputs of the highest possible quality within the given energy budget. We introduce ... -
Text Analysis of COVID-19 Tweets
(2022)During the COVID-19 pandemic many countries were forced to implement lockdowns to prevent further spread of the SARS-CoV-2, prohibiting people from face-to-face social interactions. This unprecedented circumstance led to ... -
Towards automatic significance analysis for approximate computing
(2016)Several applications may trade-off output quality for energy efficiency by computing only an approximation of their output. Current approaches to software-based approximate computing often require the programmer to specify ... -
An Updated Review of Meat Authenticity Methods and Applications
(2016)Adulteration of foods is a serious economic problem concerning most foodstuffs, and in particular meat products. Since high-priced meat demand premium prices, producers of meat-based products might be tempted to blend these ... -
