Review article: recommended reading list of early publications on atomic layer deposition - outcome of the "virtual Project on the History of ALD"
2017
Atomic layer deposition (ALD), a gas-phase thin film deposition technique based on repeated, self-terminating gas-solid reactions, has become the method of choice in semiconductor manufacturing and many other technological areas for depositing thin conformal inorganic material layers for various applications. ALD has been discovered and developed independently, at least twice, under different names: atomic layer epitaxy (ALE) and molecular layering. ALE, dating back to 1974 in Finland, has been commonly known as the origin of ALD, while work done since the 1960s in the Soviet Union under the name "molecular layering" (and sometimes other names) has remained much less known. The virtual proj…
Nouvelles technologies et aide à la compréhension de documents techniques : Construction et expérimentation d'un simulateur de fonctionnement de grue…
2001
Reading skills are more and more required to succeed professional examination. French crane drivers are concerned with this problem. In order to help them, we have conducted a study with three main steps. First, we carried out a cognitive work analysis. Second, we test several analogical modalities of written presentations focusing on the construction of a specific simulator. Finally, two experiments are presented showing a significative effect of this simulator on the comprehension of cranes technical documentation.
Los Sistemas Productivos, el Aprendizaje Interno y los Resultados del Área de Producción de Baldosas-Cerámicas
2009
El objetivo de la investigacion es comprobar la validez del modelo universal de gestion en la estrategia de produccion en el sector de fabricantes de pavimentos y baldosas ceramicas espanoles. El trabajo se centra en las decisiones de infraestructura, y pretende resaltar el efecto de los recursos internos y externos sobre la ventaja competitiva del area de produccion de las empresas. Los datos utilizados corresponden a 76 empresas espanolas fabricantes de pavimentos ceramicos. Los resultados obtenidos permiten comprobar que en este sector los recursos implantados guardan poca relacion con las prioridades manifestadas. Ademas, se demuestra que la ventaja competitiva esta mas explicada por el…
Umiejętności i wiedza politechniczna uczniów w młodszym wieku szkolnym
2013
Projektowanie i realizacja edukacji technicznej w klasach I-III
2020
Dynamiczny rozwój nauki i techniki będący synonimem dzisiejszej cywilizacji stawia przed współczesnym systemem szkolnictwa wyzwania dotyczące działań preparacyjnych mających na celu ugruntowanie wiedzy i kultury politechnicznej ucznia. Rozwój techniki umożliwił człowiekowi zmienianie swego otoczenia oraz warunków życia. Obok nauki i sztuki, coraz wyraźniej wpływa ona na całokształt życia i stanowi bardziej znaczący wskaźnik kultury technicznej współczesnego człowieka i społeczeństwa.
Smart Cities and Eu growth strategy: a Comparison among European Cities
2015
The level of interest in smart cities has been growing during these last years. The academic literature (Holland, 2008; Caragliu et al., 2009, Nijkamp et al., 2011 and Lombardi et al., 2012) has identified a number of factors that characterise a city as smart, such as economic development, business-friendly, environmental sustainability, social innovation, information and knowledge process, and human and social capital. Thus, the smartness concept is strictly linked to urban efficiency in a multifaceted way as well as to citizens’ wellbeing through the use of appropriate technologies. Instead, from a “political perspective” smartness is mainly related to the ability of using ICT (Informatio…
Utilizing ICT to prevent loneliness and social isolation of the elderly. A literature review
2016
Ageing of the population is a worldwide phenomenon. Numerous ICT-based solutions have been developed for elderly care but mainly connected to the physiological and nursing aspects in services for the elderly. Social work is a profession that should pay attention to the comprehensive wellbeing and social needs of the elderly. Many people experience loneliness and depression in their old age, either as a result of living alone or due to a lack of close family ties and reduced connections with their culture of origin, which results in an inability to participate actively in community activities (Singh & Misra, 2009). Participation in society would enhance the quality of life. With the deve…
Does technical risk dialogue entail socioeconomic valuation? : The case of scientific dispute over copper corrosion in a spent nuclear fuel disposal …
2016
Among the proponents of nuclear power, the project for the safe and secure disposal of spent nuclear fuel (SNF) in Finland is often deemed as a success story. Opponents have had difficulties getting publicity for their claims about the risks of the project. Their most powerful arguments have been mostly ethical, but on technical issues the opponents have been in a weaker position than the proponents. However, recently the risk of corrosion in oxygen-free water has become subject to scientific controversy, possibly threatening even the realisation of the final disposal of spent nuclear fuel. In Sweden, this issue has been intensively debated since 2007, but only recently has this debate take…
A simple field method to measure the hydrodynamic properties of soil surface crust
2013
The hydraulic resistance of the surface crust was determined by a combination of two infiltrometric techniques: first, a surface measurement of steady-state infiltration rate is conducted by a mini-disk tension infiltrometer (MDI); then, the surface crust is removed, its thickness is measured, and a ponded infiltration test is performed at the same site. The Beerkan Estimation of Soil Transfer parameters (BEST) method is applied to estimate the hydraulic properties of the underlying soil provided the particlesize distribution and the bulk density are known. Under the assumption of a unit gradient of hydraulic head below the soil crust, the pressure head at the interface crust-soil is derive…
Obraz i tekst w specjalistycznym języku giełdowym (na przykładzie analizy technicznej)
2017
The language of stock exchange is a terminological system based on the general language that has its own form, content, and as a medium of specialised knowledge, it is used in professional communication. In the present paper, the technical analysis is discussed as an example of a stock exchange text that functions in an accurate symbiosis with a chart. In selected formations, depicted as an illustration and a text, two frequently used techniques (that help to evaluate the stock exchange situation) are shown: a classical technique and Japanese candlestick charts. Therefore, functions of both the image and the text are depicted, as well as aims and intentions of the people whochoose the parti…
