In this article particular emphasis is laid on the compounds which constitute parts of the titles of the press articles which were published in the online version of the Süddeutsche Zeitung newspaper between 1 August 2016 and 31 October 2016. The examples selected from the author’s research corpus make it possible to state that title is the kind of text which is highly open to word games and linguistic puns. The research conducted demonstrates and explains the role that compounds – especially occasionalisms which are parts of the press article titles under analysis – play in terms of assigning functional tasks to the given press titles (headlines). The research corpus gathered for the purpose of the analysis in the present article, i.e. selected press article titles, serves as a means of describing not only general linguistic traits of the said titles from the semantic and syntactic point of view, but also, and to an even larger extent, their sociolinguistic, i.e. pragmatic functions. Particular atten-tion is drawn to the role of compounds in performing the communicative function assigned to press article titles.
The paper presents a numerical model of the novel design of the axial magnetic bearing with six cylindrical poles. The motivation behind this idea was to eliminate vibrations in rotating machinery due to the axial load. Common conception of such a bearing provides a single component of the electromagnetic force, which is not enough to reduce transverse and lateral vibrations of the armature. The proposed design allows for avoiding wobbling of the disc with the use of a few axial force components that are able to actively compensate the axial load and stabilise the disc in a balanced position. Before a real device is manufactured, a virtual prototype should be prepared. The accurate numerical model will provide essential knowledge about the performance of the axial magnetic bearing.
The resistance parameters of timber structures decrease with time. It depends on the type of load and timber classes. Strength reduction effects, referred to as creep-rupture effects, due to long term loading at high stress ratio levels are known for many materials. Timber materials are highly affected by this reduction in strength with duration of load. Characteristic values of load duration and load duration factors are calibrated by means of using probabilistic methods. Three damage accumulation models are considered, that is Gerhard [1] model, Barret, Foschi[2] and Foshi Yao [3] models. The reliability is estimated by means of using representative short- and long-term limit states. Time variant reliability aspects are taken into account using a simple representative limit state with time variant strength and simulation of whole life time load processes. The parameters in these models are fitted by the Maximum Likelihood Methods using the data relevant for Polish structural timber. Based on Polish snow data over 45 years from mountain zone in: Zakopane – Tatra, Świeradów – Karkonosze, Lesko – Bieszczady, the snow load process parameters have been estimated. The reliability is evaluated using representative short – and long –term limit states, load duration factor kmod is obtained using the probabilistic model.
