Modal parameter extraction of high speed shafts is of critical importance in mechanical design of turbo-pumps. Due to the complex geometry and peripheral components of turbo-pumps, difficulties can arise in determination of modal parameters. In this study, modal properties of a turbo-pump shaft, was studied by experimental modal analysis, and using different excitation techniques. An innovative...

An important aspect of training students a non-philological specialty is the formation foreign language communicative competence. Successful development latter impossible without all its basic components, one which grammatical competency as knowledge elements and ability to use them in communication, on hand, connections patterns established between phenomena concepts they express, other hand.T...

The article presents the experiments carried out as part of the participation in the pilot task (Modality and Negation)1 of QA4MRE@CLEF 2012. Modality and Negation are two main grammatical devices that allow to express extra-propositional aspects of meaning. Modality is a grammatical category that allows to express aspects related to the attitude of the speaker towards statements. Negation is a...

In recent work it has been demonstrated by various scholars that the use of modal verbs has changed in past decades (Krug 2000, Leech 2003, Smith 2003, and especially Leech et al. 2009). In earlier work Close and Aarts (2010) and Aarts, Close and Wallis (forthcoming) looked at the changing use of the modal and semimodal auxiliaries in spoken English. While the results of these investigations ar...

The present study investigates how advice writers employ move sequences and modal verbs to achieve intended discourse functions. This paper aims to testify two research hypotheses: 1. Advice writers of different topics employ different moves and modal verbs to achieve discourse function, and 2. The differences may imply writers’ intentions, emotion and expectancy of effects on the readers to in...

This paper describes ongoing work on the choice of modal expressions in the generation of recommendations about courses of study within the B.A.-program of the Ruhr-Universität Bochum. We focus our work on the German modal verbs müssen (must), können (can), the subjunctive form sollte (should), and dürfen (may). The idea is to combine insights from formal semantics into the meaning of modal ver...

According to Lightfoot (1979: 112), what is perhaps “most remarkable” about the reanalysis of the premodals is the subsequent development of a set of semantically identical but syntactically full verbs to fill the vacuum created. Lightfoot terms these verbs “quasimodals” and dates their appearance with modal meaning in the 15th century. I will question three of Lightfoot’s claims: the date of t...

This paper aims at investigating the acquisition of English modality among Arab learners of English as a foreign language. Specifically, the study limits itself to the perception of modal verbs as a means of expressing modality. The productive use of modal verbs were analyzed by examining written texts made by 26 fourth-year students majoring in Applied English at the University of Jordan. More...
