Facebook Goes to College; Recent Research on Educational Uses of Social Networks
2013
The number of courses offered partially or entirely online continues to grow, offering students many different ways to access academic content. Educational institutions largely use course management systems to deliver academic content, collect assignments and conduct discussions. Traditional CMS systems, however, are often underutilized and almost always require login protocols tied to students’ institutional email accounts. The ubiquity of the social networking site Facebook, demonstrates that students are willing to use online environments to exchange information and, naturally, many academics have been eager to use the networking site in their classes. The following essay examines s…
A circuit model of a 5kW fuel cell
2013
In the last few years, industrial research has been focused on renewable energy sources. Owing to combined heat-power generation option, fuel cells have attracted much interest for a wide variety of research areas. Household appliances are still the most promising applications. Fuel cell modeling is still a critical topic to focus on, affecting each stage of power system design. This paper describes an empirical method to model a proton exchange membrane fuel cell. The modeling approach is applied to a 5kW Nuvera PowerFlow fuel cell. A circuit model is proposed for further applications. PSPICE implementation is described and the parameters tuning procedure is discussed. Simulation and exper…
Decoding the Japanese Lean Production System according to a Viable Systems Perspective
2012
The increase in the complexity and variability of the business environment, due to constant and rapid changes in markets, calls for more flexible and effective production systems. Of the most valuable production systems, the Japanese lean production system (LPS) is the best known and studied, but is still not the most widely applied with success outside Japan. The reason for the low level of success of lean production outside its native country is the lack of understanding of the strong interactions which hold between enterprises and business systems. In order to fill this gap in our knowledge, we investigate the systemic interactions according to the Viable System View. To develop our anal…
Turbulence model effect on heat exchange characteristics through the neutron beam window for European spallation source
2011
PurposeThe purpose of this paper is to compare k‐ω shear‐stress transport (SST) and large eddy simulation (LES) turbulence model application effect on numerical computation of flow pattern and heat exchange characteristics through the neutron beam window region for European spallation source setup model.Design/methodology/approachTransient hydrodynamic and thermal calculations with appropriate heat sources are performed using both turbulence models and typical discrepancies in flow and thermal patterns are discussed, as well as, simulation results are qualitatively compared with experimental data for heat transfer coefficient distribution α at the window surface.FindingsContribution of grea…
Foot Print Towards Green Village - A Case on TARAGRAM
2012
This case is basically focused on particular villages of Bundelkhand region which are tending towards the self empowerment. It is about the down to earth solutions using concept of science and technology. It is about the synergistic approaches and about converting latent needs into demand. It is not compromising on quality and about increasing the productivity of all our resources within constrains of the environment to maintain ecological balance. The Development Alternatives Group, not for profit organization realized in the year of 1995 and in order to improve local economic conditions to meet basic needs, solutions were needed to respond to the needs based on local resource regeneration…
Decision making in energy planning: The electre multicriteria analysis approach compared to a fuzzy-sets methodology
1998
Every planning activity generally requires to make some choices. After a preliminary analysis of the sector under examination, a forecast of trends of input-output items, the planner must define an action plan voted to arrange all the strategies and specific interventions able to fit demand and supply during the planned time. The redaction of an action plan implies a strong effort in order to synthesize either suggestions coming from the analysis phases either all the constraints linked to technical choices. In the same time, a large number of "external" variables plays a role in orienting decision making. Some of these can be handled by numerical models (economic cost-benefit analyses, mar…
TREATMENT AND DISPOSAL OF TYRES: TWO EU APPROACHES. A REVIEW
2015
The treatment and disposal of tyres from vehicles has long been of considerable environmental importance. The main problem lies in the mixed composition of the tyres. Studies have been undertaken to modify the structure of the tyres, especially with reference to the percentage of granulated rubber incorporated, in order to improve their performance, and also to reduce their environmental impact during normal functioning (noise, particulates, etc.) and facilitate recycling and final disposal. The aim of the present study is to review and compare how used tyres are treated and disposed of in two different EU countries. The first is Italy, which has been part of the European Union since its in…
Exchange students in Finland : English language learning and use
2013
Kansainvälisyys ja kielitaito kulkevat tänä päivänä käsi kädessä ja molemmat nähdäänkin tärkeinä seikkoina yliopisto-opiskelijoiden tulevaisuuden kannalta. Euroopassa vaihto-opiskelusta on tullut yhä suositumpaa ja siihen kehottavat niin yliopistot kuin myös opiskelijoiden tulevat työnantajat sekä Euroopan Unioni, joka myös tukee hanketta taloudellisesti noudattaen Euroopan yhteistä kielipolitiikkaa. Vaihto-opiskelu nähdään hyödyllisenä niin itsenäistymisen kuin myös kansainvälistymisen kannalta, unohtamatta kielitaidon merkitystä monikielisessä Euroopassa. Merkittävä osa Suomeen tulevista vaihto-opiskelijoista pitää yhtenä tavoitteenaan parantaa englannin kielen taitoaan, huolimatta siitä,…
How can organisations and business models lead to a more sustainable society? A framework from a systematic review of the industry 4.0
2019
The concept of Industry 4.0 has been mainly addressed by the current literature from a technological perspective, overlooking the organisational and even ethical challenges related to this recent paradigm. In order to become &lsquo
North American entrepreneurs in Cuba: which entry mode and government affiliation strategy?
2018
Purpose To have success in newly liberalized markets, firms must have a plan of action before resources are committed. What some companies do not realize is that their own entrepreneurial orientation (EO) will dictate their strategies, and performance outcomes, in both their home market and abroad. In order to maximize firm performance in newly liberalized markets (such as Cuba), firms must be able to objectively gauge their own EO. The paper aims to discuss these issues. Design/methodology/approach Within this framework, the present paper will attempt to effectively measure the EO of decision-making managers from US companies that have an interest in entering the Cuban market. A final sam…
