Analysis of noise sources produced by faulty small gear units
Aleš Belšak, Jurij Prezelj, 2007, izvirni znanstveni članek

Opis: Noise source vizualization represents an important tool in the field of technical acoustics. There are many different techniques of noise source visualization. Most of them, however, are intended for a specific noise source in a specific type of acoustic environment. Consequently, a certain visualization method can be used only for certain types of noise sources in a specific acoustic environment and in a restricted frequency area. This paper presents a new visualization method of complex noise sources on the basis of the use of an acoustic camera. A new algorithm has been used, which makes it possible to visualize all types of different complex noise sources. Monopole, dipole or quadropole noise sources can be observed simultaneously. It is possible to track a moving noise source by means of an acoustic camera. In addition to that it is possible to observe various transient acoustical phenomena. Through the use in diagnostics, it is possible to define, by means of noise, the condition of mechanical systems at an advance level.

Local search engine with global content based on domain specific knowledge
Sandi Pohorec, Mateja Verlič, Milan Zorman, 2009, izvirni znanstveni članek

Opis: In the growing need for information we have come to rely on search engines. The use of large scale search engines, such as Google, is as common as surfingthe World Wide Web. We are impressed with the capabilities of these search engines but still there is a need for improvment. A common problem withsearching is the ambiguity of words. Their meaning often depends on the context in which they are used or varies across specific domains. To resolve this we propose a domain specific search engine that is globally oriented. We intend to provide content classification according to the target domain concepts, access to privileged information, personalization and custom rankingfunctions. Domain specific concepts have been formalized in the form ofontology. The paper describes our approach to a centralized search service for domain specific content. The approach uses automated indexing for various content sources that can be found in the form of a relational database, we! b service, web portal or page, various document formats and other structured or unstructured data. The gathered data is tagged with various approaches and classified against the domain classification. The indexed data is accessible through a highly optimized and personalized search service.

Mirjana Hutinski Mušić, 2012, diplomsko delo

Opis: ABSTRACT English is the biggest donor language in the world. Namely, a lot of languages still borrow words from English. However, English has itself borrowed many thousands of words from other languages. The process of language borrowing, which is widespread linguistic phenomenon, is still going on. English has always adopted loanwords from the languages of whatever cultures they have come in contact with. The history of loanwords is therefore quite complex because loanwords have often passed through a series of languages before reaching English. Although the majority of words in English have come from one of the large number of languages that belong to the Indo-European group, Modern English tends to increasingly borrow words from less known languages, even exotic ones. This graduation thesis deals with recent lexical borrowings in Modern English that came from some exotic sources. Since there are several languages from which borrowings were taken, I discuss those that are less common, even exotic. I decided to research six languages, among which are the following: Arabic, Japanese, Chinese, Portuguese, Turkish and Yiddish. In the first part of my thesis a brief history of Modern English is presented. Then a brief presentation of the process of borrowing follows. The main part of my thesis represents an analysis of the borrowings from exotic sources. Each language is analyzed separately; the words are categorized according to the different categories of various vocabulary areas. The meaning, the etymology and example sentence is provided for each word. The last part offers an analysis of the languages that contributed to the enrichment of the English language.
