In the opening part the work deals with general classification of elements used in electronic circuits, ideal and real current sources and power supplies. Further there are stated basic parameters and characteristics presented by producers in a catalogue sheet for active elements MAX435, OPA660, AD844 and MAA741 element which already belongs to the history of IC. Main attention is paid to active circuit elements with current sources driven by CCCS (Current Controlled Current Source) and AD844 (high speed monolithic operational amplifier). In the work there is described a method for determining of selected parameters of active elements with CCCS. Examined parameters were frequency characteristics of current transfer, input impedance and output impedance. The proposed method was verified by a computer simulation on above mentioned active elements by means of PSpice software. Findings along with the description are summarized at the end of the work. In the closing part of the work there is undertaken a real measure of AD844 element based on the proposed method and the findings are compared with particular simulations. However, at first a flat connection board was made by means of EAGLE software and then the measure was performed on it.
2	The importance of counter-culture in art and life Ortlieb, Paulina Elizabeth 03 February 2015 (has links) Punk rock provided not only a watershed of creativity, innovation and a do-it-yourself spirit to a culture saturated in the mainstream, it physically brought like-minded people together in a community, or rather extended family, which in today’s hyper-d.i.y. culture, is progressively declining. As early as the 1940s, theorists such as Adorno and Horkheimer warned us about alienation in a society increasingly dependent on technology. By looking to punk, and other resilient and robust counter-cultures, perhaps we can find solutions to the pitfalls of the ‘culture industry’ (Adorno, Horkheimer, 1944). My thesis, consisting of a feature-length documentary film and textual analysis, is a culmination of: ethnographic research into the punk scene in my own community; theoretical research into the sociology, ethnography and subculture theory; and my own subjectivity. My personal findings are presented to offer insight into punk philosophy and to spur discourse, rather than deliver an objective account or didactic reproach. / Graduate sub-culture music punk rock counter-culture digital age sociology Victoria BC local ethnography documentary filmmaking film studies music sociology D.I.Y musicology grounded theory etic emic qualitative research Frankfurt school subculture theory Adorno Horkheimer egalitarian democracy culture alienation community hardcore globalism internet mass culture self-identity participant observation culture industry consumerism corporatism Vancouver Island fieldwork World Wide Web freedom of expression rebellion technology constructivist subversion CCCS Chicago School nomeansno embodied oral history Somewhere to Go
