Software Defined Machine-to-Machine Communication for Smart Energy Management in Power Grids

2020

The successful realization of smart energy management relies on ubiquitous and reliable information exchange among millions of sensors and actuators deployed in the field with little or no human intervention. This motivates us to introduce a unified communication framework for smart energy management by exploring the integration of software-defined networking (SDN) with M2M communication. In this chapter, the overall design of the software-defined M2M (SD-M2M) framework is presented, with an emphasis on its technical contributions to cost reduction, fine granularity resource allocation, and end-to-end QoS guarantee. Then, a case study is conducted for a electric vehicle energy management sy…

Forest biorefineries – A business opportunity for the Finnish forest cluster

2011

Abstract Bioenergy and biomass-based products offer the greatest new opportunities for diversifying business in the forest cluster. In particular, biorefineries, which can be integrated into the pulp and paper industry, seem to have immense future potential. This article aims to explore the biorefinery concept and related new products and business operations, as well as new business strategies and company models, which are part of the biorefinery value chain. These factors, which contribute to the establishment and success of forest biorefineries, were examined using internet survey responses and compared between Scandinavia, North America and South America. This article looks at the result…

Anaerobic membrane bioreactors for resource recovery from municipal wastewater: a comprehensive review of recent advances

2021

[EN] In a paradigm shift towards a sustainable society based on the Circular Economy, wastewater treatments are rapidly evolving towards simultaneous recovery and reuse of clean water, renewable energy, and nutrients. This review examines recent advances (from 2016 to 2020) in the potential of anaerobic membrane bioreactors (AnMBRs) to serve as the core technology for municipal wastewater (MWW) resource recovery, focusing on the latest technological advances and economic and environmental innovation perspectives. The potentials and limitations of AnMBR for further full-scale application and new platforms to address these challenges are discussed, covering systems based on co-digestion, pre-…

EUROPEAN UNION EMISSIONS TRADING SYSTEM’S IMPACT ON LATVIA’S COMPETITIVENESS

2012

The goal of this paper is to analyse the general impact of the European Union Emissions Trading System (EU ETS) on Latvia’s competitiveness. The hypothesis of this paper – the EU ETS in past did not had a significant impact on Latvia’s competitiveness. At the beginning of the paper the EU ETS mechanism is discussed in the context of M.E. Porter’s identified principal factors determining state’s competitiveness. Afterwards the EU ETS operation in Latvia is described and its impact on Latvia’s competitiveness is analysed. The analysis is based on statistical data about Latvia’s 79 companies and their operation in 2005-2010, inter alia, allocations and transactions of European Union Allowances…

Energy-saving analysis of hydraulic hybrid excavator based on common pressure rail

2013

Published version of an article in the journal: The Scientific World Journal. Also available from the publisher at: http://dx.doi.org/10.1155/2013/560694 Open Access Energy-saving research of excavators is becoming one hot topic due to the increasing energy crisis and environmental deterioration recently. Hydraulic hybrid excavator based on common pressure rail (HHEC) provides an alternative with electric hybrid excavator because it has high power density and environment friendly and easy to modify based on the existing manufacture process. This paper is focused on the fuel consumption of HHEC and the actuator dynamic response to assure that the new system can save energy without sacrificin…

Una revisión a la planificación de los recursos: sobre los enfoques de evaluación y los modelos de adaptación al uso turístico

2018

Mucho se ha hablado de la planificación del turismo. Solo cabe echar una mirada a la literatura académica para encontrar decenas de propuestas metodológicas que, desde inicios de los años 50 del siglo pasado, vienen exponiéndose. A pesar de esta vorágine creativa, todas ellas acaban, finalmente, enmarcándose en uno de los cinco enfoques identificados por Hall (2008). Sin embargo, al realizar ese mismo ejercicio para el caso de los recursos, considerados la base sobre la que asentar cualquier proceso de desarrollo turístico, los resultados sobre cómo planificarlos difieren considerablemente. Esta investigación, de carácter teórico, realiza una revisión bibliográfica de los trabajos académico…

Subtractive versus mass conserving metal shaping technologies: an environmental impact comparison

2015

The scientific studies in the domain of environmental sustainability of metal processing technologies predominantly focus on conventional material removal processes, as milling and turning. Despite some exceptions, many other non-machining technologies, such as metal forming processes, are still not well documented in terms of their energy and resource efficiency. Moreover, to properly evaluate the environmental impact of a given process, a standing-alone approach is no longer sufficient. In order to offer a valuable contribution in the domain of metal shaping sustainability, the present paper proposes a thorough methodology entailing to compare, from the environmental point of view, two tr…

Open Educational Resources - in Engineering Education, Case Study at UC/AGH, UB and ULBS

2019

Abstract To change the educational scene in the epoch of the digital generation there is the possibility of using Open Education (OE) and Open Educational Resources (OER). The term “open educational resources” refers to resources with free access to use, adaptation and redistribution. The objectives of the research are to determine the degree of knowledge and use of OER in three Engineering Universities in three countries (Poland, Hungary and Romania) and to find out whether there is a relationship between the institutions in terms of knowledge and use of OER. The measurement is made by applying the survey method on a sample of n = 192. As a tool we use the questionnaire with 15 questions s…

Versatile tool for competence management - an e-portfolio management system for higher education in applied sciences

2011

In the line of outcome based education and transferability of credits, we study a Higher Education case and propose an e-Portfolio solution as a versatile tool for assessment tasks. The solution tackles the problems firstly, of accreditation of prior achievements from both institutional and experiential learning. Secondly, the developed tool carries the process of learning outcome definitions management (derived from the real employment world), and the learner self-assessment and self-reflection as well as the guidance and support for these. The e-Portfolio management system, ePofo, supports the identification, assessment, recognition and accreditation of prior learning achievements and lea…
