Seldom did Bertrand Russell discuss the movement or the trend that he himself contributed in a large measure to establish. He did not make frequent use of the term ‘analytic philosophy’, which was entering circulation in the first half of the twentieth century. However, he was fully aware of the distinctiveness of this movement that he described, using the lenses of his own philosophical preferences, referring to it as new realistic philosophy or scientific philosophy. In his later works Russell vehemently and inadequately attacked the linguistic version of analytic philosophy that originated with and was developed by Ludwig Wittgenstein in his Philosophical Investigations, to be later continued by Oxford ordinary language philosophers. The juxtaposition and consideration of various Russell’s statements on analytic philosophy from the successive stages of the development of his philosophical views help the reader to better understand Russellian metaphilosophy and follow the evolution of the philosophical tradition that he exemplified.

The aim of this article is to identify opportunities for using synergies obtained by incorporation of the two methods of management: Lean Management and Agile Management on the example of the process of column concreting. Despite the seemingly contradictory assumptions the two concepts complement each other in analysed example. The strategy is based on using the idea of "one piece flow" in accordance with the Lean Management which led to a reduction of costs due to increased turnover of formwork. At the same time the success of the project resulted in a significant dependence on the ability to provide a rapid response to changing conditions during in the maturation of concrete (depending on weather conditions, which can be expected on the basis of projections having different reliability). The simultaneous use of Lean and Agile Management allowed to achieve positive results for different scenarios of environment impact on the analysed process.

The paper presents optimization of 5-rod (5-link) suspension mechanism used in passenger cars for independent guiding of the wheels. Selected stiffness coefficients defined for five elastomeric bushings installed in joints of the suspension rods are considered as design variables. Two models with lumped parameters (i.e. elastokinematic and dynamic) of wheel-suspension-car body system are formulated to describe relationships between the design variables and the performance indexes including car active safety and ride comfort, respectively. The multi-criteria goal function is minimized using a deterministic algorithm. The suspension with optimized bushings rates fulfils desired elastokinematic criteria together with a defined dynamic criterion, describing the so-called rolling comfort. An event of car passing over short road bump is considered as dynamic conditions. The numerical example deals with an actual middle-class passenger car with 5-rod suspension at the front driven axle. Estimation of the models parameters and their verification were carried out on the basis of indoor and outdoor experiments. The proposed optimization procedure can be used to improve the suspension design or development cycle.

The study deals with stability and dynamic problems in bar structures using a probabilistic approach. Structural design parameters are defined as deterministic values and also as random variables, which are not correlated. The criterion of structural failure is expressed by the condition of non-exceeding the admissible load multiplier and condition of non-exceeding the admissible vertical displacement. The Hasofer-Lind index was used as a reliability measure. The primary research tool is the FORM method. In order to verify the correctness of the calculations Monte Carlo and Importance Sampling methods were used. The sensitivity of the reliability index to the random variables was defined. The limit state function is not an explicit function of random variables. This dependence was determined using a numerical procedure, e.g. the finite element methods. The paper aims to present the communication between the STAND reliability analysis program and the KRATA and MES3D external FE programs.
