Fads and Facts of E-Government: A Review of Impacts of E-government (2003–2009)
2010
This paper analyzes the impacts of e-government as reported in 55 first-hand empirical peer-reviewed journal publications during the period 2003–2009, using a conceptual framework to identify ICT (information and communication technology) impacts on four domains within the public sector: capabilities, interactions, orientations and value distribution. The analysis shows that research findings mostly report positive impacts in all four dimensions. In the empirical research, the majority of impacts from ICT are reported within the domain of capabilities, which is also the domain that features the most balanced mix of positive and negative findings. Findings show that although e-government has…
Introduction to Innovation, Design, and Development of ICT-Enabled Services Minitrack
2014
This minitrack's purpose is to draw researchers' attention to Innovation, Design, and Development of ICT Enabled Services for both Consumers and Enterprises. It provides a discussion forum for researchers interested in fostering a service-based approach to these areas as well as an opportunity to present and debate both design and theory-based solutions to the problems facing industry in the deployment of ICT enabled services [1-3]. In a broad sense, ICT enabled services can be defined as [1]: "systems that enable value co-creation through the development and implementation of information and communication technology enabled processes that integrate system value propositions with customer v…
Design of Scales to Assess the subjective social value of education for students in primary and secondary school.
2017
Abstract The devaluation of education, related with multiple socio-economic and psycho-school factors may be influencing decisively on academic results. A target level is observed that the socio-economic and cultural level of families can decide the student performance, however, this international trend shows inconsistent results. In addition, in different studies, we can observe that students from disadvantaged backgrounds statistics exceed expectations in performance, surpassing the expected results depending on their socioeconomic and cultural level; and students should achieve optimal results for their family situation do not get the expected performance. An interpretative hypothesis ma…
Use of neurofuzzy networks to improve wastewater flow-rate forecasting
2009
A neurofuzzy wastewater flow-rate forecasting model (NFWFFM) has been developed and tested with actual data measured at the input of two wastewater treatment facilities which treat the wastewater corresponding to 150,000 and 1,250,000p.e., respectively. Good agreements between forecasted and actual flow-rates were obtained. The artificial intelligence algorithm uses only two input variables (day of the week and average daily flow-rate of day before) and one output variable (predicted average daily flow-rate). Using three months data for training the network, a long-term forecast (one month) is made with average errors below 10%. Results were compared with those obtained by applying the Cens…
Evaluation of the effect of chance correlations on variable selection using Partial Least Squares -Discriminant Analysis
2013
Variable subset selection is often mandatory in high throughput metabolomics and proteomics. However, depending on the variable to sample ratio there is a significant susceptibility of variable selection towards chance correlations. The evaluation of the predictive capabilities of PLSDA models estimated by cross-validation after feature selection provides overly optimistic results if the selection is performed on the entire set and no external validation set is available. In this work, a simulation of the statistical null hypothesis is proposed to test whether the discrimination capability of a PLSDA model after variable selection estimated by cross-validation is statistically higher than t…
Robust H∞ sliding mode control with pole placement for a fluid power electrohydraulic actuator (EHA) system
2014
Published version of an article in the journal: International Journal of Advanced Manufacturing Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s00170-014-5910-8 In this paper, we exploit the sliding mode control problem for a fluid power electrohydraulic actuator (EHA) system. To characterize the nonlinearity of the friction, the EHA system is modeled as a linear system with a system uncertainty. Practically, it is assumed that the system is also subject to the load disturbance and the external noise. An integral sliding mode controller is proposed to design. The advanced techniques such as the H ∞ control and the regional pole placement are employed to derive t…
Common and Domain-specific Metamodel Elements for Problem Description in Simulation Problems
2014
It is well known that the multi-agent system paradigm is well suited for modelling and developing simulations of complex systems belonging to several application domains. Simulation study aims at developing simulation models useful for representing, studying and analyzing entities and their behavior in a system according to specific purposes. With our work we are trying to understand what are the right elements to be considered and included in the description of a simulation problem. In order to root our resulting metamodel in the state of the art of multi-agent simulations we started from the study of twelve papers dealing with four different application domains: Crowd Dynamics, Traffic an…
Skeletons for parallel image processing: an overview of the SKiPPER project
2002
International audience; This paper is a general overview of the SKIPPER project, run at Blaise Pascal University between 1996 and 2002. The main goal of the SKIPPER project was to demonstrate the appli- cability of skeleton-based parallel programming techniques to the fast prototyping of reactive vision applications. This project has produced several versions of a full-fledged integrated pa- rallel programming environment (PPE). These PPEs have been used to implement realistic vi- sion applications, such as road following or vehicle tracking for assisted driving, on embedded parallel platforms embarked on semi-autonomous vehicles. All versions of SKIPPER share a common front-end and reperto…
Multi-Layer Offloading at the Edge for Vehicular Networks
2020
This paper proposes a multi-layer platform for job offloading in vehicular networks. Offloading is performed from vehicles in the Vehicular Domain towards Multi-Access Edge Computing (MEC) Servers deployed at the edge of the network, and between MEC Servers. Offloading decisions at both domains are challenging for the overall system performance. Optimization at the MEC Layer domain is obtained by model-based Reinforcement Learning, while a strategy to decide the best offloading rate from the Vehicular Domain is defined to achieve the desired trade-off between costs and performance. Numerical analysis shows the achieved performance.
Location Based Information Storage and Dissemination in Vehicular Ad Hoc Networks
2010
Vehicular Ad Hoc Networks (VANETs) is an emerging type of information networks in urban areas. A lot of research has been done in the area of increasing the vehicle awareness by disseminating collision and congestion warnings, and parking place availability information. In this paper we propose a novel idea and framework for dissemination of location based information, called digital maps, which are useful not only directly for the drivers and vehicle onboard navigation systems, but also external entities, such as tourists, environmental scientists, emergency services, advertisement companies. Centralized authority defines cooperative knowledge collection tasks and disseminates orders in th…
