Opis:
The basic element of passing beam headlights is the "cut-off line". It was intended in European beam pattern as tool for correct adjustment of passing beam according good road illumination distance and oncoming drive eyes protection of excessive glare. Cut-off line was established on the one hand as a natural part separating bright and dark area in the conventional passing beam, on the other assigned its essential function of the visual aiming of headlights. It is used in laboratory practices as well as in vehicles factories and in services and technical periodical inspection. The most important is that cut-off line was defined visually and subjectively over 50 years ago. But needed aiming precision according guaranteed road visibility and glare protection is much higher than historically moulded practical cut-off performance. In paper is analysed definition of cut-off line, their performance and meaning, historical evolution and influence for technical development of headlamps design. Also, mathematical approximation and modelling of cut-off line visual perception is described. The important is analysis of practical examples of real cut-off lines, their connections with significant beam pattern characteristics and possible ambiguous aiming during type approval and during vehicle exploitation. Also, analyzed are perspectives of future cut-off line use, development or - may be replacement by other means better serving this very important task to guarantee correct adjustment beam pattern according good road illumination and protection against excessive glare.

Opis:
In scientific practice theories are allowed to posit objects believed to be fictitious. Some philosophers undermine the legitimacy of scientific practice in this respect, which leads to a philosophical problem. Various solutions have been advanced. The paper argues for a certain version of fictionalism. Since the objections against positing fiction are objections against the practical wisdom of science and are neither compelling nor easily answerable, it is suggested in the paper that if there is a way out, it is mainly a way of revealing hidden motivations by looking anew at the scientific practice from the historical perspective, one of the hopes being that it will enable us to reveal some hidden burdens of history. This suggestion determines the main line of argumentation.

Opis:
This study addressed several inconsistencies and omissions in golf putting research by testing the performance impact of target focused aiming. Participants were 22 high-level and experienced golfers, currently using ball focused aiming. Participants were allocated in a quasi-random fashion to ball or target focused aiming conditions and each performed 32 putts under competitive conditions on a natural putting green from a distance of 8 ft. Data were recorded as putts holed or missed and further categorised into putts missed long, short, left, right, short left, short right, long left and long right. There was no significant difference between conditions (p > 0.05) for any of the categories tested, despite participants’ prior extreme familiarity and expressed preference for the ball focused technique. These results notwithstanding, we discuss possible explanations for target focused benefits, including the role of vision during putting, the impact of intention during execution and possible expectancy effects. While these findings hold potential implications for golf coaching, more research is clearly required to further understand causative mechanisms and to clarify the existence and nature of advantage for one technique over the other. Based on this study, we recommend that high-level and experienced golfers might try target focused aiming as a ‘cost-free’ experiment.

This study consisted of 2 experiments. Experiment 1 examined the effects of hand posture, arm posture and body posture on hand error, while experiment 2 examined the effects of hand posture, breathing type and body posture on hand error. This study showed that more hand errors occurred in the nondominant hand, extended arm, normal breathing and standing compared with errors in the dominant hand, flexed arm, inspire–hold and sitting, respectively. This study advised people to use their dominant hand, flex their arm, inspire and hold the breath and support their body while performing fine manipulation tasks. Finally, hand error varied dramatically across the participants, indicating the need to screen individuals for fine manual manipulation tasks.

Opis:
This paper introduces my concept of cognitive equivalence (cf. Mandelblit, 1997), an attempt to reconcile elements of Nida’s dynamic equivalence with recent innovations in cognitive linguistics and cognitive psychology, and building on the current focus on translators’ mental processes in translation studies (see e.g. Göpferich et al., 2009, Lewandowska-Tomaszczyk, 2010). My approach shares its general impetus with Lewandowska-Tomaszczyk’s concept of re-conceptualization, but is independently derived from findings in cognitive linguistics and simulation theory (see e.g. Langacker, 2008; Feldman, 2006; Barsalou, 1999; Zwaan, 2004). Against this background, I propose a model of translation processing focused on the internal simulation of reader reception and the calibration of these simulations to achieve similarity between ST and TT impact. The concept of cognitive equivalence is exemplarily tested by exploring a conceptual / lexical field (MALE BALDNESS) through the way that English, German and Japanese lexical items in this field are linked to matching visual-conceptual representations by native speaker informants. The visual data gathered via this empirical method can be used to effectively triangulate the linguistic items involved, enabling an extra-linguistic comparison across languages. Results show that there is a reassuring level of inter-informant agreement within languages, but that the conceptual domain for BALDNESS is linguistically structured in systematically different ways across languages. The findings are interpreted as strengthening the call for a cognition-focused, embodied approach to translation.

Opis:
Urban traffic congestion created by unsustainable transport systems and considered as a crucial problem for the urbanised areas provoking air pollution, heavy economic losses due to the time and fuel wasted and social inequity. The mitigation of this problem can improve efficiency, connectivity, accessibility, safety and quality of life, which are crucial parameters of sustainable urban mobility. Encouraging sustainable urban mobility through smart solutions is essential to make the cities more liveable, sustainable and smarter. In this context, this research aims to use spatiotemporal data that taxi vehicles adequately provide, to develop an intelligent system able to predict traffic conditions and provide navigation based on these predictions. GPS (Global Positioning System) data from taxi are analysed for the case of Thessaloniki city. Trough data mining and map-matching process, the most appropriate data are selected for travel time calculations and predictions. Several algorithms are investigated to find the optimum for traffic states prediction for the specific case study concluding that ANN (Artificial Neural Networks) outperforms. Then, a new road network map is created by producing spatiotemporal models for every road segment under investigation through a linear regression implementation. Moreover, the possibility to predict vehicle emissions from travel times is investigated. Finally, an application with a graphical user interface is developed, that navigates the users with the criteria of the shortest path in terms of trip length, travel time shortest path and “eco” path. The outcome of this research is an essential tool for drivers to avoid congestion spots saving time and fuel, for stakeholders to reveal the problematic of the road network that needs amendments and for emergency vehicles to arrive at the emergency spot faster. Besides that, according to an indicator-based qualitative assessment of the proposed navigation system, it is concluded that it contributes significantly to environmental protection and economy enhancing sustainable urban mobility.

Opis:
In the paper was tested one of combat vehicles that is highly dynamic military vehicles, combining a high striking and fire power with high mobility and manoeuvrability. Were presented the mechanism of transfer of disturbance from the ground on the angular stabilized turret of the vehicle. Hull vibration caused by bumps in the ground. Angular and axial displacement of vehicle are the input signals acting on the turret and the gun. Two-axis stabilisation system compensates the velocities of the vehicle. Stabilisation system, automatically maintain the position of the turret at a fixed bearing in space. In spate of any motion of the vehicle in roll (hall transversal vibration) or in yaw (hall "snake-like" vibration). Torques and forces acting on the rigid body of combat vehicle turret are written in equations of motion. To examine the effect of mass inertia moment of the IFV turret on the size of first overshoot (to confirm the theoretical considerations) performed a simple experiment. Was measured the size of the angle of the first overshoot of the turret when braking rotating turret with a maximum angular velocity. Measurements were made on the IFV turret in the previously existing configuration, and when mounted on it extra weight. An experiment confirms the theoretical considerations. The results of measurements show that an increase of approximately 8 per cent of the mass moment of inertia of the turret causes about 16 per cent increase in the amplitude of the first overshoot.

Opis:
The impact of the economy and transport is currently a closely watched trend. Air transport has many advantages that favor it over other modes of transport. However, the environmental impact of avia- tion on the environment is not negligible, despite the fact that many important aviation organizations are constantly assessing the level of this impact and taking appropriate action on that basis. Despite the adoption of measures to increase air safety, accidents continue to occur. Among other things, they have a negative impact on the environment. The negative impact of an aviation emergency re- sults from the leakage of liquids into the soil and water, and the leakage of flue gases and combustion products of aircraft construction materials in the event of a fire into the air. This article deals with the analysis of aviation accidents in a selected area aiming to identify the parameters affecting the environment in these emergencies.

Opis:
The palace in Krzesimów was built in the classicist style at the beginning of 19th century. The building is the part of the palace-park complex entered into the register of monuments because of its historical, aesthetical and landscape values. From 1970s, it is the headquarters of a social welfare home. Over the years, this function enforced many changes in the functional layout of the building to adapt it to the needs of people with various types and levels of disability. Despite many minor renovations and modifi cations, the palace didn’t undergo complete overhaul, which would greatly improve the technical condition of the original fabric. This aim of article is to analyse introduced functional changes, which were supposed to facilitate the use of the building by the handicapped, and to consider what actions must be undertaken in order to improve its technical condition. The authors of the paper underline the need to start renovation works on the basis of the archive documentation, as well as conducted survey and research of its current technical condition.

Opis:
In this study, the polyacrylic acid (PAA) was studied as a selective depressant for calcite in the selective flotation of fluorite and calcite, and the implications of this process for the separation of fluorite ore were studied using micro-flotation tests, and the results were analyzed with Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS) analyses. The flotation tests indicated that the preferential adsorption of PAA onto calcite rather than sodium oleate (NaOl) could selectively depress the flotation of calcite, allowing its separation from fluorite at pH 7. The zeta potential of calcite became more negative with the addition of PAA rather than with NaOl. However, the characteristic features of PAA adsorption were not observed for fluorite, suggesting that NaOl preferentially adsorbed on the surface of fluorite, or that PAA could be replaced by NaOl on the fluorite surface. FT-IR and XPS analysis were utilized to obtain a better understanding of the mechanism by which PAA was more strongly adsorbed on the calcite surface than NaOl. This was revealed to occur through chemical bonding between the carboxyl group of PAA and the hydroxyl groups of the Ca species on the calcite surface, modifying the structure of the adsorbed layer. A possible adsorption mechanism, along with a postulated adsorption mode for the surface interaction between PAA and calcite, is proposed.

Opis:
The aim of this article is to outline school psychologist’s interventions, which might be useful while supporting a chronically, somatically ill child in their re-entry to school, aiming at broadening their peers’ knowledge about the chronic disease and positively changing their attitudes towards the ill child. In the first part, the importance of peer relationships in childhood and adolescence, the relation of their quality to school absences and the positive role of school attendance in the process of adapta-tion to illness and recovery, are presented. Then, the arguments for school psychologist to become an agent of child’s positive school re-entry are provided. A framework of tasks to be performed by psy-chologist in the school setting is outlined. The second part focuses on the interventions which might be useful to meet expectations the environment has towards school psychologist in case of an ill child’s return to school. Among them, negative messages’ delivery, educational workshops design and deli-very, promoting self-advocacy of the child, preventing violence and supporting child’s siblings have been chosen as important areas of actions related to the child’s peers. A selection of suggestions how to deal with these diverse fields of activity has been outlined, basing on re-entry models, as well as on useful directions and interventions to prevent bullying and support children in developing psychoso-cial competences, which are discussed in research reports, metaanalyses and professional literature.
