Opis:: In the article the issue of process structures in the autobiography of Alice Salomon and a relation between biographical and collective trajectory. Besides the introductory information on the pioneer of social work in Germany herself and her international career in organizations of women's movement in the article the analysis of process structures in her autobiography is presented together with theoretical inspirations, methodological remarks and data on the text. In contrast to the analysis of autobiographical utterances of Rudolph Hoess enclosed in three articles by M.Czyzewski and A.Rokuszewska-Pawelek, which to some extent constituted the pattern of construction of the plot, the analysis of Alice Salomon autobiography allows to notice the situation when the collective trajectory does not absorb individuals but makes them build their own identity by means of biographical projects despite experiencing suffering associated with the collective trajectory. By the comparison of R.Hoess and A.Salomon autobiographies an attempt was made to emphasize the complexity of the German nation's fate of the Nazi period.

Opis:: This paper introduces a new algorithm of trajectory reproduction and trajectory tracking for nonholonomic systems. The endogenous configuration space approach is employed as a guideline in the algorithm derivation. The derivation uses a trajectory reproduction error, which is an integral of the difference between the resultant trajectory and the desired trajectory over the motion horizon. Such a definition of the error allows to solve both the trajectory reproduction as well as the trajectory tracking problem. Considerable attention in the paper has been paid to the implementation aspects of the algorithm. The nonparametric approach is used together with a higher order of the integration method. The algorithm efficiency is illustrated with computer simulations accomplished for two nonholonomic systems: the dynamics of the double pendulum with a passive joint, and the kinematics of the unicycle.

Opis:: The first mechanical construction of swivel walker is from year 1963 and it was aimed for support movement of people with disabilities. This solution was very difficult and it was main reason for purpose of electromotoric module, which facilitates movement and reduce effort of people with disabilities. Therefore further research in this area are still provided. In this paper trajectory of swivel walker with electromotoric modules is described. To analyze the tilt and trajectory structure of the walker SolidWorks software was implemented.

Opis:: The development of directional drilling made designers work out numerous measurement devices for spatial location of the borehole axis. The borehole trajectory can be determined on the basis of very accurate calculation methods. The authors present a brief characteristic of devices for measuring dogleg angle and azimuths as well as methods for calculating the spatial placement of borehole axis, i.e.: – average angle method, – tangential method, modified to balanced tangential method, – radius of curvature method (RCM), – minimum curvature method. Calculations and graphical representations of deviations obtain ed with these four methods were performed for three selected trajectories of borehole axes (2D), increase/decrease of dogleg angle and 3D, increase/decrease of dogleg angle and azimuth with the use of COMPASS software (part of Halliburton Landmark package).

Opis:: The paper describes six methods of optimal and game theory and artificial neural network for synthesis of safe control in collision situations at sea. The application of optimal and game control algorithms to determine the own ship safe trajectory during the passing of other encountered ships in good and restricted visibility at sea is presented. The comparison of the safe ship control in collision situation: multi-step matrix non-cooperative and cooperative games, multi-stage positional non-cooperative and cooperative games have been introduced. The considerations have been illustrated with examples of computer simulation of the algorithms to determine safe of own ship trajectories in a navigational situation during passing of eight met ships.

Opis:: The paper is concerned with the problem of safe trajectory planning for approaching during emergency STS (Ship to Ship) transfer operation with oil spill. The safe trajectory means that the way points does not cross in the area of the environment with the static and dynamic obstacles and at the same time satisfies ship's stopping and speed deceleration performance. The evolutionary path planning algorithm is used to determine trajectory designed as way points and straight line segments between them. The way points - ship positions and velocity can be treated as reference value to support navigator in decision making during Approach Manoeuvre and to mitigate the risk of collision which mostly results from exceed velocity of approaching. The task of trajectory planning is defined as constant optimization process to minimize trajectory length, course alteration and maximize safety in a navigational environment. This paper examines exemplary navigational scenario based on emergency STS accident.

Opis:: This paper contributes to a modified guidance scheme based on a trajectory tracking method which is dedicated for an artillery rocket with a finite set of single use solid propellant side thrusters. Frequency modulation of pulses was used to achieve effective firing logic. The proposed control law is applicable in the last phase of flight when the rocket reaches the vertex of the trajectory. A correction engine activation sequence was chosen in such a way that possibility of rocket axial unbalance is minimized due to motors firing. Numerical simulation results indicate that significant dispersion reduction was achieved and the number of activated side rocket thrusters is minimized.

Opis:: Since Polish migrants began entering the UK labour market in the post-accession period, there has been a significant amount of case study research focusing on the impact of this large migrant group on the UK economy. However, ten years after enlargement, there is still insufficient information regarding the labour market mobility of Polish migrants residing in the UK for the longer term. The available research on this topic is largely concentrated in urban settings such as London or Birmingham, and does not necessarily capture the same patterns of labour market mobility as in non-urban settings. Using qualitative data collected in three case study locations – urban, semi-urban and rural – in the South Wales region from 2008–2012, this article has two main aims. First, given the proximity of the case study locations, the article highlights the diversity of the Polish migrant characteristics through the samples used. Second, using trajectories created from the data, this article compares the variations among the labour market movements of the Polish migrants in each sample to determine what characteristics influence labour market ascent. Through this comparative trajectory analysis, the findings from this article point to the relative English language competency of migrants as the primary catalyst for progression in the Welsh labour market across all three case study regions. The secondary catalyst, which is intertwined with the first, is the composition of the migrants’ social networks, which enable, or in some cases disable, labour market progression. These findings have significant implications in the national and in the supranational policy sphere regarding the employment of migrants as well as their potential for cultural integration in the future.

Opis:: The paper presents results of a ship's safe trajectory planning method verification - the Trajectory Base Algorithm, which is a deterministic approach for real-time path-planning with collision avoidance. The paper presents results of the algorithm’s verification from different ships’ perspectives and with changing strategies of target ships. Results prove the applicability of the algorithm in the Collision Avoidance Module of the Autonomous Navigation System for Maritime Autonomous Surface Ships.
