Opis:
Surface 3D reconstruction is a topic of great relevance and it has a wide range of applications in many fields such as mechanics, bioengineering and arts. Nowadays optical systems for 3D contouring such as those based on structured light projection are becoming more and more widespread. The possibility to get shape information without any contact with the object, in fact, is a great advantage in some fields such as, for example, cultural heritage. For this class of objects, however, the issue connected with inhomogeneous reflectivity must be taken into account. Due to the different level of reflectivity, in different areas of the object, it comes out that the contrast of the projected pattern changes and, as a direct consequence, the achievable accuracy can change from part to part. In this paper, a study on the possibility to implement an adaptive lighting algorithm is performed allowing to adapt illumination in order to compensate the local inhomogeneities in terms of surface reflectivity.

Opis:
High temporal and spatial resolution of radar measurements enables to continuously observe dynamically evolving meteorological phenomena. Three-dimensional (3D) weather radar reflectivity data assimilated into the numerical weather prediction model has the potential to improve initial description of the atmospheric model state. The paper is concentrated on the development of radar reflectivity assimilation technique into COAMPS mesoscale model using an Ensemble Kalman Filter (EnKF) type assimilation schemes available in Data Assimilation Research Testbed (DART) programming environment. Before weather radar data enter into the assimilation system, the measurement errors are eliminated through quality control procedures. At first artifacts associated with non-meteorological errors are removed using the algorithms based on analysis of reflectivity field pattern. Then procedures for correction of the reflectivity data are employed, especially due to radar beam blockage and attenuation in rain. Each of the correction algorithms is connected with generation of the data quality characteristic expressed quantitatively by so called quality index (QI). In order to avoid transformation of data uncertainty into assimilation scheme only the radar gates successfully verified by means of the quality algorithms were employed in the assimilation. The proposed methodology has been applied to simulate selected intense precipitation events in Poland in May and August 2010.

Opis:
The recent trend of using aluminium alloys instead of steel has reached the transportation industry, where increasingly, more parts are made of aluminium. An example is the belt pulley, applied for combustion engines for energy transmission. This part should be strong, durable, and lightweight. Aluminium-silicon alloys are a good choice, moreover, even when the surface is anodised, also because of their moderate inertia control and excellent wear characteristic during mechanical operations. Since aluminium is lightweight yet mechanically durable and anodised, it is an ideal belt pulley to use, especially in high-temperature operations. However, the main question is what type of Al-Si alloy, casting method and anodisation method should be used in terms of energy adsorption, having long-term properties for a lifetime, has to be applied. For this reason, this paper presents the influence of the chemical composition, casting method and anodising parameters on the structure and thickness of the anodic layer produced on aluminium alloys, as well as on the albedo value as an ability to reflect or absorb light. The aluminium alloys, AlSi12Cu1 and AlSi9Cu3, were used as research materials, obtained using different casting methods. The goal of this work was to determine the optimal combination of the anodisation conditions and materials for maximising the reflectivity factor of the surface, as a very important factor, determining the energy amount absorbed by an anodised surface. For further improvement of these surface properties as well as for enhancement of the properties and strengthen the material produced with different aluminium alloys production methods, different alloying additives were added. In addition, the mechanical properties of the surface layer were measured, where a remarkable hardness increase was obtained, and the best combination in form of AlSi12Cu1 high pressure cast was found with the highest albedo factor among all tested surface variants.

Opis:
Our view of organizations, labour and the competencies of managers will soon need to change. In the postmodern and post-Fordist world, economy and organizations function differently than they did in the 20th century. Workers and managers will have to face new expectations. Not only has reflectivity become one of the key organisational factors; it is also taught, learnt and shaped. Drawing on an authoethnographic model and action-research, authors of this paper provide an education and development tool that managers and workers can use to develop and trigger reflectivity. Picture ethnography, coaching philosophy and hermeneutics are theoretical bases for the construction of a new model of self-development.

In recent years magnetic tunnel junctions have been intensively studied and incorporated in magnetic random access memory devices and magnetic sensors, where large tunnelling magnetoresistance ratios are preferred. The largest tunnelling magnetoresistance values until now have been observed in magnetic tunnel junctions with MgO barriers and CoFeB electrodes after annealing of the junction above the recrystallization temperature of the amorphous CoFeB layers. We used X-ray reflectivity and polarized neutron reflectivity to study [Co_{60}Fe_{60}B_ {20}//MgO]_{x14} multilayers with the MgO layers prepared by different methods and annealed at different temperatures in order to compare the interface quality and the structural changes induced upon annealing.

Opis:
Educational situation analysis sheet (AnAlySE) was used as a tool while working with university students of early education. The work with AnAlySe was monitored in order to answer the question of its meaning in developing the ability to reflect on the everyday educational reality. The observation of students’ proceedings, the interviews with them and the analysis of their work lead to the conclusion that the sheet constitutes a specific space for obtaining knowledge and developing certain skills in teacher’s both individual and group work. It fosters developing the ability to learn “with” others and “from” others “in” and “from” the everyday educational reality.

Opis:
Entering adulthood is a process which for many people becomes a source of disappointment and frustration. If young people aren’t prepared for the encounters with difficulties which can be met while searching for their own place in life during their school education, they become helpless and have a “cracked” reflectivity, as noted by Margaret S. Archer. At the same time one cannot ignore the gradual emergence of a new social class – the precariat – a dangerous class, as we are warned by Guy Standing. This group consists predominantly of young adults who are often seeking work far from home without any guarantee of employment. The role played by the sense of agency is indisputable. Life chances depend on whether one acts with his/her free will. The only hope for proper social functioning is community building because, according to Charles Taylor, individualism, the predominance of instrumental rationality, and the lack of active citizenship constitute a kind of contemporary threat.
Wkraczanie w dorosłe życie to proces, który dla wielu osób staje się źródłem rozczarowań, frustracji. Jeśli młodzi ludzie w okresie szkolnej edukacji nie zostaną przygotowani na zetknięcie z trudnościami, jakie ich mogą czekać przy poszukiwaniu swojego miejsca w życiu, to stają się ludźmi bezradnymi, o „pękniętej” refleksyjności (określenie Margaret S. Archer). Nie można nie dostrzec tworzenia się nowej i – jak przestrzega Guy Standing – groźnej klasy społecznej, prekariatu. W tej grupie dominują młodzi dorośli poszukujący rynku pracy nawet daleko od domu rodzinnego, bez gwarancji zatrudnienia. Rola sprawstwa jest bezsporna. Szanse życiowe zależą od działania podmiotu zgodnego z wolną wolą. Nadzieją na właściwe funkcjonowanie społeczne jest budowanie wspólnoty, ponieważ indywidualizm, prymat rozumu instrumentalnego, brak aktywności obywatelskiej, zdaniem Charlesa Taylora, stanowią rodzaj współczesnego zagrożenia.

Opis:
In this work $TlBiTe_2$ were grown by a modified Bridgman technique and examined samples had different lateral dimensions of twins, ranging from 0.1 μm to 1 μm. The average lateral size of the twins seems to affect free carrier concentration and plasma frequency. Infrared spectra were analyzed by two models, the extended Drude model and a generalized empirical model of frequency-dependent damping factor. Increase in size of twins affects the electronic properties and hence plasma reflectivity and free carrier concentration of $TlBiTe_2$.

The maxima characteristic of the binary HgA$\text{}^{IV}$ compounds can be revealed in the mixed crystals spectra, but their position depends on the crystal composition. There is no duplication of the spectral features in spite of the different energy position of the maxima for HgSe and HgTe. This suggests that the virtual crystal approximation could be used to describe basic optical properties of HgSe$\text{}_{1-x}$Te$\text{}_{x}$.

I mean here these people, who in the world of multiple and competing choices, make decisions in a thoughtful, rational and metodological? way. They become to be known as reflective parents. The introduction of the reflectivity category into considerations on the contemporary parenthood is to open a news pace of conceptualising processes and phenomena connected with the fulfillment of the parental role, selfunderstanding in this role and in the relations with a child.

Based on the assumption that only moving, metallic parts of a turbine cause echoes indelible by standard filtering used in radar signal preprocessing, a method of preliminary evaluation of such maximum potential clutters was developed. The method takes into account how great a part of a turbine is really illuminated by a radar beam and for this part calculates a RCS (Radar Cross Section) and its equivalent radar reflectivity. A very detailed description of the model is given in this article in order for it to be easy to implement in any calculation system. Discussion of the influence of the main simplifications assumed in this model, as well as a comparison of the theoretical results with example data in operational mode of radar work, are included in this article.

Opis:
This paper addresses a problem which has been central in teacher education for several decades: how to encourage critical reflectivity in prospective EFL1 teachers. This problem is set within the larger context of the field of school, family and community partnerships. The rationale behind choosing this context is that there is a gap between the significance of various types of such partnerships for the well-being of the whole child, and a lack of deeper understanding of the issue among prospective teachers. The overwhelming majority of research in the matter, conducted mainly in the USA, covers the areas of pre-school, early school and special education (e.g. Lindberg 2014). Additionally, there are few research-based articles related to building the partnership skills of preservice EFL teachers. Therefore, in this paper we attempt to describe the cases of three prospective EFL teachers involved in the process of preparing small scale empirical projects related to the parents’ perspectives. As shown in the paper, engagement in such long term and complex enterprises does not automatically develop the subjects’ deeper understanding of the important role of various types of parent involvement in the (academic) success of children.

Opis:
The Norwegian novelist Knut Hamsun’s outstanding early novel Pan. From Lieutenant Thomas Glahn’s Papers (1894) is often acknowledged as a manifestation of the specificity and profundity of Hamsun’s perception of nature. Contrary to the prevailing opinion, I argue that the novel’s main protagonist cannot be simply seen as the happily fulfilled “man of nature” for whom he wishes to pass. In a critical dialogue with the post-Romantic interpretations of Pan and drawing on some classic philosophical traditions (i.e. Rousseau, Schiller) as well as the modern Norwegian scholarship, I explore the psychological dimension of Hamsun’s masterpiece and present Glahn as an individual who attempts to erase or at least mystify within a personalized narrative the conflict between the objective world and his subjective perception of reality. This predicament seems essential to understanding Glahn’s character and ipso facto Hamsun’s less obvious position in the philosophical debate on the essence of modernity conceived as “Disenchantment”. By carefully following Glahn’s narratives centered on his experience of nature, I reveal their artificial and simulating character. Such a reading allows me to argue that Hamsun’s Pan concurs in a subtler language of literature with the philosophical acknowledgement, dating back to Rousseau, of the impossibility of the individual’s return to the pre-modern time, as if to the realm of original, transcendental sense and immediacy of our experience of the world. The horizons of the modern – perhaps suffice to say: mature? – historicized and highly reflexive consciousness cannot be transgressed; the Romantic sensitivity, in its naïve search for the authentic experience of nature as a source of the self and the sense, can only regain it in discourse, which amounts to positing nature as a beautiful appearance and thus compensating for one’s dramatic feeling of alienation from nature and being conceived of as a metaphysical “wholeness”.

Opis:
The paper presents the results of study of convective cloud development over land and sea. The study was based on data from the Gdańsk-Rębiechowo radar and upper air sounding from the Łeba aerological station. Radar data from the classical channel were analyzed for the atmosphere scanned at 6 elevation angles of the antenna beam. Vertical profiles of the atmosphere along selected paths presenting radiolocation reflectivity in the detected cloud structures were produced using the recorded radiolocation reflectivity. Conclusions concerning the cloud structure, the physical state of water in the clouds and the thermodynamic state of the atmosphere were formulated as the results of comprehensive analysis of the radar and upper air sounding data. The obtained values of selected parameters and indices were used to quantitatively describe selected physical processes and to formulate forecasts concerning weather phenomena that might pose threats to land, air and sea transport as well as for some industrial and agricultural branches. The developed method of radar and aerological data processing will be applied to further studies of convective clouds in other regions. It will also enable to assess the impact of environmental conditions on the development of convective processes.

Opis:
The glancing-angle reflectivity profiles in samples containing an X-ray waveguide layer are studied. Oscillations observed at angles within the region of resonance and above, are interpreted by angle dependent interference of the monochromatic X-ray beam in thin layer. The discussion is extended to the structures composed of more than one layer. Experimental reflectivity spectra recorded with Cu K$\text{}_{α}$ radiation are compared with the theoretical calculations. It leads to the model of oscillations in reflectivity consistent both for the resonant and non-resonant regions, and clarifies interpretation of oscillations in the region above the resonances. A brief discussion of potential applications of the reflectivity spectra to the studies of structure of thin layers is done.

Opis:
Within the last quarter of the century social sciences have been witnessing a quiet methodological revolution. The noticed expansion of interpretative approaches and the growing popularity of quality research may be perceived as a form of academic rebellion against the omnipotent scientistic doctrine with its guaranteed monopoly for setting methodological standards. The movement of quality researchers, particularly in its radical and critical version, undermines a thesis that recognised methodological standards reflect universal rules of the cognitive reason. In this approach the methods of science are a collection of conventions negotiated within reserachers’ communities and social and cultural provenance.

Opis:
The article aims at presenting the technique of critical incidents analysis as a tool to promote reflectivity among inexperienced foreign language teachers. Critical incidents, often used in social and educational studies, are defined as meaningful and important situations (both positive and negative) that trigger individual’s reflection and help him/her realize his/her beliefs and practices. The article provides characteristics of the technique of critical incidents analysis. Data gathered from inexperienced student teachers (n= 30) indicate strong emotional involvement of the subjects in the study . Their descriptions of critical incidents concentrated mostly on negative situations resulting from their lack of experience with classroom routines, low self-confidence and feelings of inadequacy.„Nauczanie to uczestniczenie w powodzi zdarzeń”(Tripp 1993; Kwiatkowska 2008: 173)

Opis:
The fundamental reflectivity spectra of monocrystalline CdTe, implanted with Ag ions at room temperature and with Er ions at liquid nitrogen temperature, are investigated in the 0.5-6.0 eV energy range. The analysis of the obtained spectra leads to the suggestion that temperature of implantation influences the obtained results much more decisively than values of other parameters. For the implantation carried out at 300 K no significant changes in reflectivity spectra are observed regardless of magnitude of the ion dose (up to 5 × 10$\text{}^{15}$/cm$\text{}^{2}$) and this fact, in our opinion, is due to the self-annealing effect. For samples implanted at temperature 77 K with comparable doses of ions, however, the characteristic changes of shape and intensity of reflection coefficient spectra appear. The manner of this changes gives evidence that temperature 77 K is low enough to make the radiation induced lattice defects stable (frozen-in) which are responsible for the observed behaviour of CdTe fundamental reflectivity spectra.

Opis:
The infrared reflection spectra of the organic quasi-one-dimensional semiconductor triethylammonium (TCNQ)$\text{}_{2}$ between 80 and 300 K are reported. Characteristic changes in the temperature dependencies of the bands assigned to the donor vibrations are observed. An interpretation of the electron-molecular vibration coupling in terms of the dimer theory is discussed. It is concluded that the thermal evolution of the spectrum corroborates the semiconductor-semiconductor type of phase transition attributed to the cation disorder.
