Towards more equity concerning quality of Urban Waste Management services in the context of cities
2018
Abstract An innovative combined evaluation approach is proposed in the present paper to deal with the issue of the performance measurement and comparison of Urban Waste Management (UWM) services in the context of cities. The ELECTRE III method is initially considered as tool able to execute a multi-criteria analysis aimed at ranking UWM systems based on their integration and sustainability levels. The latter are comprehensively evaluated via the recently developed “Wasteaware” Integrated and Sustainability Waste Management indicators framework, which takes into account physical components and governance aspects of UWM systems. Then, on the basis on ELECTRE III results, a practical gaps inve…
Where Are Corporate Thought Patterns to be Found in Legislation and Planning Processes? The Example European Water Framework Directive (Wo Lassen Sic…
2008
Planning Processes are always the result of a societies thought pattern. This paper analyses the thought patterns that influenced the treatment of water sheds in the last centuries and how the change of these patterns has influenced the European Water Framework Directive.
Stationary battery systems in the main world markets: Part 1: Overview of the state-of-the-art
2017
The role of energy storage systems (ESSs) is becoming more and more important in modern power grids, mainly because of the higher penetration of intermittent renewable energy sources (RESs), such as solar and wind power, spurred by advantageous support policies carried out in several countries. The fluctuation nature of the energy produced by RESs is indeed leading to emerging power quality issues or to renewable curtailments. ESSs can be used to balance generation and demand of electricity over time, allowing a higher penetration of RESs into the power network. The energy storage industry is evolving rapidly, and new electrochemical technologies are entering the market. Besides, most elect…
An Innovative Conversion Device to the Grid Interface of Combined RES-Based Generators and Electric Storage Systems
2015
This paper is focused on the development of an innovative device, which is based on a bidirectional converter, for the interface to the supply utility grid of combined renewable-energy-source-based generators and electric storage systems. The device can be controlled so as to ease the interface between the low-voltage grid and photovoltaic or wind generators combined with lithium-ion $\hbox{LiFePO}_{4} $ batteries, taking into account the requirements of the reference technical standards for users connection and offering different ancillary services. The operational functioning of the device, the architecture, and its electronic components, as well as laboratory and field test activities an…
Implications of the Marketing Strategy for Exporting MSEs from Developing Economies
2010
Purpose: This paper reviews the export literature and identifies the marketing challenges faced by exporting MSEs from developing economies. The paper further explores ways in which MSEs can adjust their marketing strategies to circumvent the challenges faced. Design/methodology/approach: It reviews both theoretical and empirical perspectives in export performance globally and with a special focus on studies done in developing economies. The literature synthesis is done in order to develop a conceptual model which will be used as guidance in future research. Findings: Previous studies have shown several types of marketing challenges which are faced by MSEs from developing economies. These a…
Management Structure Based Government Enterprise Architecture Framework Adaption in Situ
2017
Part 1: Regular Papers; International audience; The fragmentation of the public sector makes it difficult to manage strategically and architecturally as a whole. Enterprise Architecture (EA) is considered as an improvement to that. Architectural modeling and visualization of the general management strategy plans along with parallel database development in a local government forms the primary data in the longitudinal case study using Action Design Research Method. To find a proper organizational fit for the EA framework in public sector, we reflect on how the current state architectural descriptions got organized in situ in a deep corporate hierarchy, and what were the emerging management ne…
Specification of modelling languages in a flexible meta-model architecture
2010
Originally, meta-models were used to specify the structure (abstract syntax) of modelling languages. This is reflected both in meta-languages like MOF and Ecore, and the four-layer meta-model architecture. Presently, meta-modelling is used for specification of complete languages. In this situation, it turns out that the traditional meta-languages are not always expressive enough to capture all language aspects. This usually implies the use of more than one metalanguage in the meta-model architecture to cover the different language aspects. There are many approaches to address this challenge. In this paper, we analyze these approaches, and based on this analysis, we re-think the meta-model a…
A CAN Fieldbus Based Architecture for Distributed Control Systems Implementation
2003
Abstract The application of distributed systems theory to the implementation of industrial control systems is one of the best options to develop simple, scalable and physically distributed control systems. Following this line, our group has proposed a new architecture based on Rule Nets (RN) as an HLP over CAN fieldbus for the implementation of Distributed Systems. This architecture has been applied to several control applications, obtaining excellent results. The most outstanding feature of the architecture was its simplicity in the control systems design, without any efficiency loss. New capabilities have been added to improve its features and develop new analysis tools, in order to incre…
An expert system hybrid architecture to support experiment management
2014
Specific expert systems are used for supporting, speeding-up and adding precision to in silico experimentation in many domains. In particular, many experimentalists exhibit a growing interest in workflow management systems for making a pipeline of experiments. Unfortunately, these type of systems does not integrate a systematic approach or a support component for the workflow composition/reuse. For this reason, in this paper we propose a knowledge-based hybrid architecture for designing expert systems that are able to support experiment management. This architecture defines a reference cognitive space and a proper ontology that describe the state of a problem by means of three different per…
Fifth Generation Networking Principles for a Service Driven Future Internet Architecture
2010
Published version of an article published in Wireless Personal Communications, vol. 57:393-411. Also available from the publisher at: http://dx.doi.org/10.1007/s11277-010-0076-7 The vision of all-IP networks where IP forms the simple common layer understandable across the whole network has undeniable advantages. However, such simplicity comes as a major hurdle to flexibility and functionality to the architecture. This is evident from the increasingly numerous and complex engineering solutions and optimizations required to accommodate essential qualities like mobility, security, realtime communication support etc or to mitigate the shortcomings inherent in the 'traditional Internet' architec…
