Quasi-3D model for calculation of radiation leakage currents in modern submicron SOI MOSFET structures is proposed. Instead of the fully 3D modeling is proposed to solve two tasks: 2D modeling of the traditional MOSFET cross-section and 3D modeling of the side parasitic transistor. The radiation-induced leakage current simulation in the 0.35 μm SOI MOSFET structure with taking account ionizing radiation with a dose of up to 500 krad was simulated. The results of the simulation show that in comparison with the traditional fully 3D modeling, which requires 11 hours of computer time, the computer time for the IdVg characteristic was reduced to 71 minutes (i.e. the computer time decreased by 9 times).
Temperature phenomena are universal, relatively easily perceptible by humans and crucial for them, but their conceptualisation involves a complex interplay between external reality, bodily experience and evaluation of the relevant properties with regard to their functions in the human life. The meanings of temperature terms are, thus, both embodied and perspectival. Rather than reflecting the external world objectively, they offer a naïve picture of it, permeated with folk theories that are based on people’s experience and rooted in their culture (cultural models). Languages differ as to how many temperature terms they have and how these categorize the temperature domain in general Closely related languages can show remarkable differences in their uses of temperature adjectives, even when these are cognates to each other; conversely, temperature systems can show remarkable areal patterns. Temperature terms can belong to different word classes, even within one and the same language (adjectives – ”cold”, verbs – ”to freeze”, nouns – ”coldness”). Languages vary in their word-class attribution of temperature concepts: thus, for instance, many languages lack temperature adjectives. Word-class attribution and, further, lexicalization of temperature expressions and the possible syntactic constructions in which they can be used are sensitive to their semantics.
Temperature meanings are often semantically related to other meanings, either synchronically (within a polysemantic lexeme) or diachronically. Thus, temperature concepts often serve as source domains for various metaphors and are extended to other perceptional modalities (‘hot spices’, ‘warm colour’). Temperature meanings can also develop from others, e.g., ‘burn, fire’ >’hot’, or ’ice’ > ’cold’. Finally, the meanings of temperature terms can also change within the temperature domain itself, e.g. ‘warm, hot’ > ‘lukewarm’, as in Lat. tep- ‘warm’ vs. English tepid ‘lukewarm’. While some languages show extensive semantic derivation from the temperature domain, others lack it or use it to a limited degree. Languages vary as to which temperature term has predominantly positive associations in its extended use (cf. ‘cold’ in Wolof vs. ‘warm’ in the European languages), partly due to the different climatic conditions.
Temperature terms have, on the whole, received relatively little attention. Cross-linguistic research on temperature is mainly restricted to Sutrop (1998, 1999) and Plank (2003), which focus on how many basic temperature terms there are in a language and how they carve up the domain among themselves. There has been no cross-linguistic research on the grammatical behaviour of temperature expressions, apart from a few mentions.
In theoretical semantics, temperature adjectives have mainly figured in discussions of lexical fields, antonymy and linguistic scales (cf. Lehrer 1970, Cruse & Togia 1995, Sutrop 1998, cf. also Clausner & Croft 1999). Koptjevskaja-Tamm & Rakhilina 2006 suggest that linguistic categorization of the temperature domain is sensitive to several parameters, that are important and salient for humans and can be distinguishable by simple procedures relating to the human body. Within the Natural-Semantic Metalanguage, Goddard & Wierzbicka (2006) propose the general formula for describing the language-specific meanings of temperature terms via reference to fire.
Extended uses of temperature words have been studied indirectly in cognitive linguistics, primarily in research on the metaphors underlying emotions, e.g. AFFECTION IS WARMTH (Lakoff & Johnson 1997:50) and ANGER IS HEAT (Kövecses 1995, also Goossens 1998; cf. also Shindo 1998-99). An important question raised in Geeraerts & Grondelaers (1995) is to what degree such extensions reflect universal metaphorical patterns or are based on common cultural traditions. The current empirical evidence for the suggested metaphors is still relatively meagre.
Pressure sensors on the basis of thin-film tenzorezistorny nano – and microelectromechanical systems with the frequency output signal, steady to influence of temperatures are considered. Original schemes of frequency converters and topology of an arrangement of tenzoelement on a membrane of a sensitive element of the sensor are submitted.
