AC electric linear drive for paralell kinematics structures of robots
Nejedlý, Petr ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
Design of linear actuator for parallel kinematic structure is described in this master´s thesis. The parallel kinematic structure is described in the first part. Open kinematics structure and close kinematics structure are compared. Their benefits and disadvantages are also mentioned. Construction of some parallel robots is illustrated. Linear actuators of different company are described. Mechanical parameters and construction of linear actuator are compared. Design of linear actuator is described in practical part of master´s thesis. A few variation of linear actuator are introduced. Individual variants are evaluated by Multicriteria Decisional Analysis and a final conception is selected. Final conception of linear actuator is elaborated. Reasons for selection of every part of linear actuator are given and basic mechanical calculation design part is made. FEA analysis of the structural part of linear actuator is made. Design of linear actuator is evaluated in the final part.

Production of holder by solid forming
Nejedlý, Petr ; Novotný, Karel (referee) ; Kopřiva, Miloslav (advisor)
The project elaborated in frame of engineering studies branch 2307. The project is submitting design of technology production of holder by solid forming of steel 12 020.0. Pursuant to of the literary pursuit a problem of die forging and calculation was designed forging on a vertical cranked press LMZ 1600 and with nominal forging force 16MN (producer ŠMERAL Brno). The lower ejector is using for extrusion component.Heating billet is accomplished by using induction furnance type SOP 400kW.For trimming is used trimmning press LKOA 200 with force 2 MN. For holding of dies is used holder QLZK 1600/UC, dies are made of instrumental steel 19 552.9. A part of this project is economic estimation of production and produce of manufacturing drawings.

On the semantic shift 'blow' – 'needless or frivolous talk'
Nejedlý, Petr ; Vajdlová, Miloslava
There is a marginal part of (Old) Czech lexis, the root *klas- family (cf. klás /n/ 'ludibrium; iocus'), so far unrecorded in Czech etymological lexicons. The article considers various Slavic as well as non-Slavic possibilities of the family’s origin and outlines formal and content contexts of this onomatopoeically motivated family on the background of some Old Church Slavic lexical units and on the basis of the principle of elementary relationship.

On two expressions of negative mental state (hatred, fear)
Nejedlý, Petr
There is no indisputable recorded evidence of a fundamental non-negative form of the Old Church Slavic and Slavic verb nenaviděti (it is necessary to revise some opposite views in this respect). Later records of the verb naviděti can be, from the semantic point of view, explained rather as prefi xed derivatives of viděti. Nenaviděti had therefore in all likelihood originated as an artifi cially created denotation of an abstract concept based on the spheres of Christian doctrine. 2. As primarily Old Czech records indicate, the word family of the Slavic verb plašiti contains the IE root *pel-, the initial meaning of which is one of motion: 'chase, run aft er'. The sememe '(rapid/hasty) motion' needs to be considered as fundamental for already the earliest stages of Slavic languages; the sememe 'fright, fear' is – along with the corresponding intransitive verbs – secondary.

Publicly accessible electronic resources to the study of the historical Czech in The Department of Language Development of The Institute of the Czech Language AS CR, v. v. i
Černá, Alena M. ; Lehečka, Boris ; Nejedlý, Petr ; Šimek, Štěpán ; Vajdlová, Miloslava
The article introduces two internet sources designated to the study of Older Czech language (13th to 18th centuries); both have been designed and run by The Department of Language Development at The Institute of the Czech Language at the Academy of Sciences of the Czech Republic. The first source, Vokabulář webový [Web Vocabulary] (http://vokabular.ujc.cas.cz), makes texts, images and audio materials available to the study of Older Czech language. The accessible materials are, primarily, both modern and historical dictionaries, amongst which the most salient is the, gradually growing, Elektronický slovník staré češtiny [Electronic Old-Czech Vocabulary] that treats Old-Czech lexicon from the dawn of Czech language to the end of the 15th century. Furthermore, Vokabulář includes electronic editions of the works originating in the period from the 13th century to the beginning of the 19th century, presented both as continuous texts and in the corpus version; digitalized copies of Older-Czech grammar books; basic scientific literature; audiobooks of Older-Czech texts; and software tools utilized for the work with historical texts. The second source is Lexikální databáze hu-manistické a barokní češtiny [Lexical Database of Humanistic and Baroque Czech] (http://madla.ujc.cas.cz). It records the Czech vocabulary of the 16th to 18th centuries based on the excerption of the authentic contemporary texts (both old prints and manuscripts): Lexical database illustrates the Czech vocabulary with direct quotations, including stating the source. Thus, Lexical Database partly substitutes the missing Czech vocabulary of the mentioned period.

The reflection of space in the Czech vocabulary of the late Middle Ages
Nejedlý, Petr
The way the medieval people observed, interpreted and evaluated the space that surrounded them has been reflected also in the Old-Czech vocabulary – in designation of space, space relationships, operations in and with space, and in the word-formation motivation of many lexical units. From the pattern of lexical meanings and their semantic development it can be deduced which lexical units designing space and space relationships were central in the given period (cf. for example pút vs. cěsta – both path, road; journey), what was the hierarchy of the relevant concepts and their denomination (cf. povětřie - air; atmosphere; wind; weather vs. počěsie - suitable time; favourable weather; weather), and what was the extralinguistic reality (legal conventions – cf. veřějní - public, originally - placed on a door or gate; fight technique – cf. podvrci - forge, fake, foist, originally - push (weapon) under one's arm, etc.).
