Opis:
Research on temporal comparison has shown that people dissociate themselves from their past to attain a positive self view. Social comparison research has demonstrated that the distinctness of contextually activated information determines whether a recalled self exerts assimilation or contrast effects on the current self. However, hardly any study addressed individual differences. Also, very little is known about whether the ease or difficulty to date past events and experiences influences current self-judgments. We present a new scale capturing the degree of the current self time extension. Three studies support the notion that temporal self-extension determines how past selves are accessed and processed, regarding both the abstractness with which self-knowledge is retrieved and the experienced temporal distance to the past. These findings have important implications for temporal as well as social comparison processes.

Opis:
The asymptotic stability of discrete-time and continuous-time linear systems described by the equations xi+1 = Ākxi and x(t) = Akx(t) for k being integers and rational numbers is addressed. Necessary and sufficient conditions for the asymptotic stability of the systems are established. It is shown that: 1) the asymptotic stability of discrete-time systems depends only on the modules of the eigenvalues of matrix Āk and of the continuous-time systems depends only on phases of the eigenvalues of the matrix Ak, 2) the discrete-time systems are asymptotically stable for all admissible values of the discretization step if and only if the continuous-time systems are asymptotically stable, 3) the upper bound of the discretization step depends on the eigenvalues of the matrix A.

Opis:
Magnetic-geared permanent magnet (MGPM) electrical machine is a new type of machine by incorporating magnetic gear into PM electrical machine, and it may be in operation with low-speed, high-torque and direct-driven. In this paper, three types of MGPM machines are present, and a quantitative comparison among them is performed by finite element analysis (FEA). The magnetic field distribution, stable torque and back EMF are obtained at no-load. The results show that three types of MGPM machine are suitable for different application fields respectively according to their own advantages, such as high torque and back EMF, which form an important foundation for MGPM electrical machine research.

Opis:
The present paper aims to discuss recruitment advertising as a promotional genre, as well as to investigate its rhetorical structure and provide a tentative comparison between job ads and the central promotional genre, i.e. marketing-type (or ‘mainstream’) advertising. Based on an analysis of a corpus comprising 400 online job advertisements, the study discusses the communicative purposes of the genre (juxtaposed with the general goals of promotional genres), and attempts to identify and describe the prevalent structural patterns found in the sample. It also offers a rough comparison between job ads and prototypical/marketing-type advertisements in terms of the rhetorical structure and other defining characteristics, following Bhatia (2004, 2005) and Cook (2001). The analysis confi rms numerous similarities between job advertising and the central promotional genre, yet it also identifies major differences, particularly those pertaining to the communicative goals, structural elements (company identifi cation, targeting the market, justifying the ‘product’, offering benefits/incentives, making use of testimonials and pressure tactics), as well as other signifi cant features including the level of ‘artistry’, the number of voices involved, generic stability, provoking controversy, being parasitic upon other genres, occupying the space at the centre/periphery of attention.

Opis:
The paper offers a critical outlook on the taxonomy of motion situations proposed by Zlatev et al. (2007, 2010) and its application to cross-linguistic comparison of motion-emotion metaphors (Zlatev et al. 2012). The critique is then applied, together with the results of a corpus-based analysis of motion metaphors by Woźny (2013), to creating a new, language independent taxonomy of motion situations, reflecting the naive physics – a linguistically coded, widespread set of intuitive beliefs concerning motion, proven to be resistant to the passage of time or the achievements of modern physics, extensively described by the body of literature collectively known as Disaster Studies (e.g., Champagne et al. (1980), Larkin et al. (1980), McCloskey (1983), Halloun et al. (1985), Hammer (1995), diSess a (1988, 1993, 1996)).

Opis:
Nasal consonants feature in phonological systems of both Polish and Welsh, yet, apparently, they are active in a different manner and to a different degree. The paper aims fi rst at establishing the ‘players’ – the prototypical segments and their nonprototypical variants. The relevant inventories seem to be comparable, however, the contextually and non-contextually dependent realizations vary considerably in the two systems. Polish nasal consonants do not appear to have terribly complex phonology, their occurrence and phonotactics seems to be dictated through use (Bybee, 2001). Nasal segments in Welsh, on the other hand, are actively involved in the alternation of Initial Consonant Mutation, where they occur as strengthened equivalents of plosives through (possibly) assimilation (Buczek, 1995). It remains to be discovered whether nasals in general (and the so-called voiceless nasals in particular) are independent categories or rather, additionally they feature as nonprototypical variants of plosives. There is, indeed, substantial overlap here. Secondly, the paper looks at certain instances of what appears to be sonorant lenition in Welsh, where nasals [m] and [n] are broken into complex consonantal diphthongs [mh] and [nh] respectively (Pilch, 1975). In its entirety, this paper examines the two systems, hinting at the similarities and exploring the points of difference, especially in cases where the similar phonetic realizations possibly result from different categorical membership.

Opis:
RT-PCR assays for detection of BRSV, based on four different sets of primers were optimized and evaluated for their sensitivity and specificity. Primers used in this study were specific for genes encoding three BRSV proteins, nucleoprotein N and glycoproteins F and G. Our results indicated that RT-PCR with primers B7:B8 for G protein was the most efficient in detecting BRSV. Starters B7:B8 reacted specifically only with BRSV strains, no cross-reaction with other closely related viruses to BRSV was observed. RT-PCR sensitivity was also high and amounted to 101.66 TCID50. Starters for F and N genes of BRSV were not sufficiently specific and cross-reacted with RNA of HRSV. RT-PCR with primers for the genes F and N of BRSV was characterized by a lower sensitivity than RT-PCR with primers B7:B8. In conclusion, RT-PCR specific to a sequence of glycoprotein G gene, seemed to be the most useful for BRSV detection.

The aim of this paper is to describe daily patterns and changes in time use of people dealing with elderly informal care in Poland. Based on Time Use Survey 2004 and 2013 we show that with increasing population of adults requiring care the profile of average caregiver also changes. We observe more caregivers. More often they are women and more often are retired. In consequence average time spent on caregiving also increases. We conclude that this trend will continue and therefore both market and state suppy of the caregiving services is required.

Opis:
The techniques of photogrammetric reconstruction were compared to the laser scanning in the article. The different conditions and constraints were introduced for reconstructed images, e.g. different materials, lighting condition, camera resolution, number of images in the sequence or using a-pripori calibration. The authors compare the results of surface reconstruction using software tools avaliable for photogrammetric reconstruction. The analysis is preformed for the selected objects with regard to laserscanned models or mathematical models.
Skanowanie 3D jest procesem pomiarowym realizowanym przy użyciu urządzeń optycznych z wykorzystaniem różnorodnych metod pomiarowych. Do odwzorowania głębi analizowanej sceny skanery 3D wykorzystują najczęściej techniki fotograficzne. Jednakże pojedyncza fotografia jest w tym przypadku niewystarczająca, konieczne jest wykorzystanie dodatkowych informacji, np. wiedza o położeniu laserowego prążka w obrazie albo rozkład światła strukturalnego w połączeniu z analizą kształtu metodą triangulacyjną za pomocą skalibrowanego układu pomiarowego. Ostatnio też do rekonstrukcji 3D wykorzystuje się nieskalibrowane obrazy pochodzące z różnych punktów obserwacji. Niestety przy zastosowaniu tych technik pojawia się szereg niedokładności pomiarowych przekładających się negatywnie na jakość wynikowego odwzorowania. Dodatkowo różne techniki skanowania wprowadzają odmienne ograniczenia dotyczące uwarunkowań akwizycji. Przykładowo, skanowanie laserowe w skanerach triangulacyjnych wymaga dokładnego odwozrowania odbicia zniekształconego prążka promienia laserowego, natomiast w przypadku technik fotogrametrycznych istotna jest analiza różnorodności obserwowanej tekstury obiektu. W artykule porównano fotogrametryczne techniki rekonstrukcji z technikami scanowania laserowego. Przenalizowano uwarunkowania i ograniczenia związane z akwizycją danych pomiarowych, takich jak: różnorodność wykorzystanych materiałów, warunki oświetleniowe, rozdzielczość kamery, liczba obrazów w sekwencji, wpływ kalibracji wstępnej. Autorzy dokonują porównania zrekonstruowanych powierzchni wyselekcjonowanych obiektów w odniesieniu do zrekonstruowanych obiektów wzorcowych pozyskanych metoda˛ skaningu laserowego wysokiej rozdzielczosci, bądź do wzorcowych modeli matematycznych.

Opis:
The authors of this article were guided by the desire to show the profitability of using renewable energy sources and to facilitate decisions for future investors as to their choice. The article classifies energy sources and methods for converting renewable energy sources (RES) and presents a technical comparison of two electricity supply systems: a photovoltaic system and a household wind farm for a selected building. A residential, single-family building, inhabited by a family of three, was adopted for analysis. Photovoltaics, the use of solar radiation energy to produce electricity, is classified next to wind farms as the most dynamically developing renewable energy technology. When analysing in terms of technology renewable conversion methods that provide us with electricity, the better installation is the photovoltaic installation. By analysing the cost of renewable energy conversion technologies that provide us with electricity, the photovoltaic system becomes more beneficial, because with a similar investment price we get a much shorter payback period than in the case of a backyard wind power station.
Autorzy niniejszego artykułu kierowali się chęcią pokazania opłacalności wykorzystywania odnawialnych źródeł energii i ułatwienia podjęcia decyzji przyszłym inwestorom, co do ich wyboru. W niniejszym artykule sklasyfikowano źródła energii i metody konwersji odnawialnych źródeł energii oraz podjęto próbę porównania, w aspekcie technicznym i kosztowym dostarczania energii elektrycznej do wybranego budynku mieszkalnego, dwóch z nich: fotowoltaiki i siłowni wiatrowej. Przedstawiono porównanie techniczne dwóch systemów dostarczania energii elektrycznej: systemu fotowoltaicznego i przydomowej elektrowni wiatrowej, do wybranego obiektu budowlanego. Do analizy przyjęto budynek mieszkalny, jednorodzinny, zamieszkiwany przez 3 osobową rodzinę. Przyjęto roczne zapotrzebowanie na energię elektryczną równe 3500 kWh, co jest równe średniemu europejskiemu rocznemu zapotrzebowaniu na energię dla gospodarstwa domowego. W domu posiadamy tradycyjną instalację elektryczną, do której podłączamy zaproponowane rozwiązania.

Opis:
This paper proposes four different cost-effective configurations of a hybrid energy storage system (HESS) in an electric city bus. A comparison is presented between a battery powered bus (battery bus) and supercapacitor powered bus in two configurations in terms of initial and operational costs. The lithium iron phosphate (LFP) battery type was used in the battery bus and three of the hybrids. In the first hybrid the battery module was the same size as in the battery bus, in the second it was half the size and in the third it was one third the size. The fourth hybrid used a lithium nickel manganese cobalt oxide (NMC) battery type with the same energy as the LFP battery module in the battery bus. The model of LFP battery degradation is used in the calculation of its lifetime range and operational costs. For the NMC battery and supercapacitor, the manufacturers’ data have been adopted. The results show that it is profitable to use HESS in an electric city bus from both the producer and consumer point of view. The reduction of battery size and added supercapacitor module generates up to a 36% reduction of the initial energy storage system (ESS) price and up to a 29% reduction of operational costs when compared to the battery ESS. By using an NMC battery type in HESS, it is possible to reduce operational costs by up to 50% compared to an LFP battery ESS.

Opis:
The electromagnetic and output performance characteristics of three (3) different types of double stator permanent magnet machines are quantitatively compared and presented in this study, in order to determine the most promising machine topology amongst the considered machine types, for potential practical applications(s). Two-dimensional (2D) and three-dimensional (3D) finite element analysis (FEA) methods are deployed in the computation of the performance metrics using ANSYS-MAXWELL software. The compared machines in this work are designated as: Machine 1, Machine 2 and Machine 3, respectively. The investigated machines have varying structural arrangements and two separate excitation sources. Machine 1 has its magnets situated in the outer stator with corresponding armature windings on both inner and outer stators. The magnets of Machine 2 are located in its inner stator while it has armature windings on both inner and outer stator parts. More so, Machine 3 is equipped with magnets in its inner and outer stators, though without armature windings on the inner stator section. The considered performance metrics include: inducedelectromotive force (induced-EMF), torque, power, demagnetization, losses and efficiency. The results show that the investigated Machine 3 has higher induced-EMF value and more sinusoidal electromotive force waveform than the other compared machines. Consequently, Machine 3 also has larger electromagnetic torque and power. Moreover, Machine 1 has the best flux-weakening potential, obtained from both the ratio of its maximum speed to base speed and the flux-weakening factor ( kp).
