A Robustness Approach to Reliability
2012
Reliability of products is here regarded with respect to failure avoidance rather than probability of failure. To avoid failures, we emphasize variation and suggest some powerful tools for handling failures due to variation. Thus, instead of technical calculation of probabilities from data that usually are too weak for correct results, we emphasize the statistical thinking that puts the designers focus on the critical product functions. Making the design insensitive to unavoidable variation is called robust design and is handled by (i) identification and classification of variation, (ii) design of experiments to find robust solutions, and (iii) statistically based estimations of proper safe…
Probabilistic Approach to the Design of Photovoltaic Distributed Generation in Low Voltage Feeder
2006
This paper presents the probabilistic approach to the design of photovoltaic (PV) distributed generation (DG) and its impact on low voltage (LV) feeder. Monte Carlo simulation is used to predict solar radiation and load, and an exact method is used to solve the power flow. The method is tested on two study cases, and the results are compared with those from deterministic approach based on commonly used scenarios. The probabilistic approach is shown necessary to obtain the optimum PV rating based on technical constraints and different objectives, including accepting a reasonable risk when needed. The results also indicate that PV-DG in a realistic case will most probably improve the voltage …
Unidirectional Direct Load Control through Smart Plugs
2014
International audience; Balancing energy demand and production is be-coming a more and more challenging task for energy utilities also because of the larger penetration of renewable energies which are more difficult to predict and control. While the traditional solution is to dynamically adapt energy production to follow time-varying demand, a new trend is to drive demand itself. Most of the ongoing actions in this direction involve greedy energy consumers, like industrial plants, supermarkets or large buildings. Pervasive communication technologies may allow in the near future to push further the granularity of such approach, by having the energy utility interacting with residen-tial appli…
Ideas in the History of Nano/Miniaturization and (Quantum) Simulators: Feynman, Education and Research Reorientation in Translational Science
2015
Cultural history of nanominiaturization, computing, quantum computing and simulating is necessary to comprehend human character and place it in the whole of living beings. Ideas in the history of physics by Feynman, etc. are valued by the questions that generate. A series of questions, answers and hypothesis introduces the nature of the history of nanominiaturization, providing facts. Nanotechnology adds a third dimension to the periodic table of the elements. Thinking about computers was useful. It must do with learning computers possibilities and physics potential. Provisional conclusions follow. (1) Nature (space–time) is not classical but discrete; quantization is a different kind of ma…
A statistic approach of cables ageing in MV lines on thermal and electrical combined stress
2006
The paper introduces a methodology that through a probabilistic characterisation of load for MV network, and implementing a life model for combined electric and thermal stresses, simulates the process of ageing of the insulating materials evaluating the expected life time of the cable. Such evaluation is necessary to the possibility of assuming less restrictive thermal overloading limits on electrical cables, with the consequential increase on reserve that cables could offer. A numerical example is reported to better explain the methodology
Lean design improves both health-care facilities and processes: a literature review
2014
This article presents a literature review of the challenges and possibilities for Lean design in modern health-care facilities. Many of today's health-care facilities are in dire need of renovation since limited financial resources among health-care demand improved work process efficiency, safety and employee well-being. Lean philosophy has been successfully implemented into hospitals with up-and-running hospital processes, but has not been thoroughly tested as a design methodology. The principles of Lean do not contradict with user-centric, participatory or ergonomic design approaches and thus the possibilities of using Lean as a complementary design methodology to the aforementioned appro…
Toward Successfully Integrating Mini Learning Games into Social Virtual Reality Environments : Recommendations for Improving Open and Distance Learni…
2017
Social virtual reality environments, also known as 3D virtual immersive environments, are threedimensional computer-generated virtual spaces that are increasingly used in attendance-based and distance education. Thanks to their unique characteristics that separate them from two-dimensional virtual learning environments, social virtual reality environments can enhance distance education efficacy when used in combination with applying instructional methodologies such as situated learning, experiential learning and game-based learning. The authors of this paper describe the design and findings of a research study on game-based learning in social virtual immersive environments. The research met…
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,…
"Hei mitä tää ny tarkottaa?" : experiences of intercultural communication and linguistic shock while using English abroad
2016
Globalisaation ja kansainvälistymisen myötä korkeakouluopiskelijoiden kansainvälinen liikkuvuus on lisääntynyt huomattavasti. Ulkomailla oleskelu on tarjonnut monille hyvinkin positiivisia kokemuksia, mutta uudessa kulttuurissa eri kielellä toimiminen voi aiheuttaa myös yllättäviä ongelmatilanteita. Tutkimuksen teoriataustan aloittaa katsaus kansainväliseen opiskelijaliikkuvuuteen, jonka jälkeen esitellään muutamia tärkeimpiä kulttuurienvälisen viestinnän teorioita. Kulttuurienvälinen viestintäkompetenssi on myös olennainen tässä tutkimuksessa, joten myös siitä keskustellaan. Kielishokki ilmiönä esitellään aluksi sekä kulttuurisesta että kielellisestä näkökulmasta, jonka jälkeen tarkastella…
