Opis:: To explore the boundary between quantum and classical physics in the context of quantum entanglement, the particle localization via measurement induced entanglement on photons incident onto a distinguishable, massive non-interacting two-particle system was studied. The specific case of how particles acquire well defined spatial localization when light is scattered off and detected was considered. The localization process studied both qualitatively and quantitatively was observed to be valid for particles which were initially localized as well as initially completely delocalized. The localization scheme was also observed to be extremely sensitive to its initial conditions. Furthermore, a difference in the localization scheme in terms of the number of scattering events was observed between monochromatic photons and photons with variable frequencies. From all these results it was apparent that we can interpret the uniquely quantum features of entanglement in terms of classicality.

Tytuł:: Przestrzenna lokalizacja dźwięku u osób z niepełnosprawnością wzrokową
Autorzy:: Rosiński, Adam
Wydawca:: Wydawnictwo Uniwersytetu Gdańskiego
Opis:: Autor w niniejszym artykule stara się ukazać nowe możliwości zastosowania i wykorzystania systemu elektroakustycznego w pracy z osobami z niepełnosprawnością wzrokową. Przedstawione możliwości wykorzystania systemu elektroakustycznego oraz specyficznych umiejętności słuchowych w życiu codziennym osób z niepełnosprawnością wzrokową jest celem nadrzędnym niniejszej pracy. Ukazane problemy stanowią wyłącznie wybrany fragment z szerokiego i wieloaspektowego obszaru w zakresie obcowania z dźwiękiem i kształcenia w zakresie oceny słuchowej dźwięku osób niewidomych. Właściwie podjęte kształcenie, wykorzystanie specyficznych umiejętności słuchowych osób z niepełnosprawnością wzrokową oraz zastosowanie specjalnego systemu elektroakustycznego, może wpłynąć na zwiększenie bezpieczeństwa wzmiankowanych osób w życiu codziennym w przestrzeni publicznej, jak i w pomieszczeniach zamkniętych.
In the article the author attempts to show a new possibilities of applying and exploiting the electroacoustic system at working with people with visual impairment. The text exemplifies how to employ electroacoustic system and specific auditory capabilities in everyday life of people with visual impairment. The problems undertaken in the study merely shape only a small part of a broader and multi-faced issue, referred either to sound experience or training the auditory assessment of the sound in people with visual impairments. The accurate schooling, employing specific auditory skills of the visually impaired, as well as the use of special electroacoustic system may increase safety in their everyday life, either in the open or closed spaces.

Opis:: The use of higher-order ambisonics in spatial sound recordings makes it possible to increase the accuracy of recording information about the direction from which the sound comes to the listener. However, with binaural ambisonic sound reproduction, the listener's ability to locate the sound source accurately may be limited. This paper presents a comparison of the listener's ability to locate a sound source during binaural listening to recordings made with first and third order ambisonic microphones. The analysis was carried out for two types of signal: pink noise and ringing sound. The analysis of localization errors depending on the ambisonics order, azimuth and elevation angles as well as the type of signal is presented. The obtained data indicate that in binaural reproduction of the ambisonic sound the localization errors in the azimuth plane were smaller for the third order ambisonics, compared to the first order. In the elevation plane both for first and third order the errors were significant.

Opis:: Dysfunctions of the organ of hearing are a significant limitation in the performance of occupations that require its full efficiency (vehicle driving, army, police, fire brigades, mining). Hearing impairment is associated with poorer understanding of speech and disturbed sound localization that directly affects the worker’s orientation in space and his/her assessment of distance and location of other workers or, even most importantly, of dangerous machines. Testing sound location abilities is not a standard procedure, even in highly specialized audiological examining rooms. It should be pointed out that the ability to localize sounds which are particularly loud, is not directly associated with the condition of the hearing organ, but is rather considered an auditory function of a higher level. Disturbances in sound localization are mainly associated with structural and functional disturbances of the central nervous system and occur also in patients with normal hearing when tested with standard methods. The article presents different theories explaining the phenomenon of sound localization, such as interaural differences in time, interaural differences in sound intensity, monaural spectrum shape and the anatomical and physiological basis of these processes. It also describes methods of measurement of disturbances in sound localization which are used in Poland and around the world, also by the author of this work. The author analyzed accessible reports on sound localization testing in occupational medicine and the possibilities of using such tests in various occupations requiring full fitness of the organ of hearing.

Opis:: Planowanie i rozwój centrów logistycznych w Polsce uzależniony są od wielu uwarunkowań, które wpływają na podejmowanie decyzji lokalizacyjnych na poziomie regionalnym. Autor dokonuje analizy różnorodnych uwarunkowań, zwracając uwagę na aspekt polityki przestrzennej oraz rolę sektora publicznego w kreowaniu ich rozwoju. Porusza także problem rozwiązań zagranicznych, które mogą być cennym źródłem doświadczeń dla władz samorządowych w Polsce. Artykuł powstał w znacznej mierze na bazie własnych badań empirycznych autora, w latach 2008-2011, dotyczących centrów logistycznych w regionie łódzkim – jako studium przypadku. Wiele mechanizmów i doświadczeń zidentyfikowanych w tym regionie można odnieść – na zasadzie podobieństw rozwojowych – również do innych regionów i poczynić uogólnienia wnioskowe.
Planning and development of logistic centers in Poland are dependent on a number of conditions that have an influence on making investment decisions made on the regional level. The author makes an analysis of varied conditions, taking particular note of the aspect of spatial politics as well as the role of a public sector in supporting logistic centers development. There has also been brought up the problem of foreign solutions in terms of localization of logistic centers what can be a valuable source of experience for selfgovernment authorities. The presented article has for the most part developed on the basis of the author’s own examinations conducted in years 2008-2011 considering the logistic centers in Lodz and its region – treated as the case study. The series of mechanisms and experiences taking place in the city and the region can be also used in reference to other cities or urban agglomerations and generalized.

Opis:: The aim of the study is to evaluate the influence of agglomeration effects on corporate performance in Germany. The assessment carried out by investigating the effects of localization and urbanization. For this reason, the work was presented to the theoretical basis; it formulated the problem, methodology of the research and analyzed the influence of various factors on the number of employees in leading industries of Germany. We use the Panel data, a large-scale German establishment survey covering around 3477 companies of 9 industries located in 83 cities (14 lands). The study covers the period 2007 – 2014 years. The paper presents a linear model and two nonlinear models – the model with the addition of the square of companies` age and the model using the natural logarithm of the number of employees. The best model was chosen by using Akaike information criterion (AIC) and Schwarz (BIC), i.e. the linear model. The study found that localization effects have a positive impact on the number of employees, while the effects of urbanization – negative. In addition, it most strongly depends on the number of employees by region and industry. In the largest regions there is the largest population and respectively, the number of workers in it, so the agglomeration effects in the populous region is higher than in the other regions. The age of the company has a positive effect on the company’s number of employees: with an increase in the age of 1 year, the number of employees is increased by 21 people.
