Opis:
The paper deals with the testing of composite materials based on aluminium and polymer microparticles. The aim of the research was to determine an influence of a content of a microparticle filler on mechanical properties of the polymer particle composite and adhesive bonds (material structural carbon steel S235J0). A preparation of adhesive bonds and a process of testing of the adhesive bonds were in accordance with the standard CSN EN 1465. The adhesive bond strength was increased when adding the aluminium and polymer powder filler. The adhesive bond strength increase was the highest at the adhesive bond with the adhesive in the form of the composite (15 g of the filler : 100 g of the matrix). The adhesive bond strength increase was 14.3% (13.68 ± 0.43 MPa). Adhesive bonds evinced an adhesive type of a fracture surface. By adding the filler in a form of microparticles there was a change of the failure type on adhesive-cohesive and a cohesive type. Fracture surfaces and an adhesive bond cut was examined with SEM (scanning electron microscopy) using a microscope MIRA 3 TESCAN.

Opis:
The paper investigates the effects of degreasing, surface preparation methods in adhesive bonding and con adhesive joint strength. Five types of degreasing agents were used in the study: acetone, extraction naphtha, Ultramyt, Wiko and Loctite 7061. The degreasing operation was performed by three methods: rubbing, spraying and immersion. Strength tests were performed on single-lap adhesive joints of hot-dip galvanized metal sheets made with Loctite 9466 adhesive according to the above variants of surface preparation. The experimental results demonstrate that adhesive joint strength is significantly affected by the applied degreasing agent. Moreover, the method of application of the degreasing agent is crucial, too. The results of strength testing reveal that the most effective degreasing method for hot-dip galvanized metal sheet adhesive joints is spraying using extraction naphtha. Thereby, degreased samples have the highest immediate strength and shear strength. The use of extraction naphtha is also effective in combination with degreasing by rubbing; however, it is not effective when used in combination with immersion, as reflected in the lowest strength results.

Opis:
The magnetic field and beat-treatment dependences of the ultrasound velocities at constant magnetic field (CH) and at constant magnetic induction (cB) and magnetomechanical coupling were investigated in Fe62.5Co6Ni7.5Zr6Cu1Nb2B15 alloy strips in an as-quenched state and after annealing above the Curie temperature. After annealing above 350oC (up to 390oC) the magnetomechanical coupling coefficient (k) was three times higher than that for asquenched state (0.10-012), i.e. k = 0.32-0.37. The minimum values of the cH (= 3.6 km/s) were observed after annealing in the temperature range from 350 to 390oC at 75-100 A/m. There are equal or somewhat higher values of bias field for the minimum of the cH than in some other iron-rich amorphous alloys. Effect de was very small for as-quenched samples. When the samples reached the magnetic saturation, the domain structure vanished and then the Hooke's law was valid, i.e. EH = EB = E, where E was then material constant, known as Young's modulus and then the ultrasound velocities are also material constant.

The paper investigates the compression strength of samples of regenerative polymer mass RM 101 Resimetal Metal Repair Pasta manufactured by Rendor. The effect of weather conditions on selected mechanical properties of the tested mass is examined. The samples are subjected to seasoning at room temperature, in an environmental chamber, and in a thermal shock chamber. The samples for strength testing are made according to the adopted method. It has been observed that the samples seasoned at room temperature have the lowest strength, while the highest strength is exhibited by the samples subjected to seasoning in an environmental chamber at a temperature of 70°C and humidity of 95%. In addition, the paper compares the strength properties of regenerative polymer masses manufactured by Chester Molecular, Belzona, and Unirep, as well as of the widely used epoxy compound Epidian 57 mixed with the Z-1 curing agent with those of the Rendor mass. The properties of the above masses are obtained from the available literature.

Opis:
In mid-scale and large five axis overhead gantry type milling machines, the vertical z-slide (ram) often constitutes one of the most sensitive and critical components regarding stiffness, structural vibrations and thermal influences. During machining, the z-slide is loaded by (quasi-) static process and drive forces, transient acceleration forces, periodic excitations by the tool engagement, as well as by thermal effects resulting from altering ambient conditions, heated chips, cooling lubricant and power losses in drives, guides and bearings. Deflections, thermal deformations and vibrations of the z-slide lead to geometric machining errors and inacceptable surface location errors at the workpieces. Furthermore, instable cutting conditions and regenerative chatter limit applicable material removal rates and, thus, productivity. In this work, a newly developed hybrid material structure for an exemplary z-slide, involving metal parts and mineral cast, is introduced. Structural optimization methods as well as process simulation techniques were applied in order to derive the final design solution. The integration of active cooling circuits for thermal stabilization is investigated and the use of fibre optical strain sensors is analysed with respect to a state monitoring of the machine tool component.

Opis:
Semiconductor microcavities are monolithic multilayer heterostructures grown by molecular beam epitaxy. They allow the confinement along the growth axis of both photons between the Bragg reflectors and excitons in quantum wells. If the exciton-photon coupling matrix element is large enough compared to the line width, the system is said to be in the strong coupling regime. In that case a quantum well exciton couples to another discrete state: the photon mode of a planar microcavity with the same in-plane wave vector, to give rise to quasi-stationary states named cavity polaritons. In this regime, the Fermi golden rule does not hold any more and the optical properties, linear or nonlinear, are strongly related to polariton features. A review of the optical properties of CdTe-based microcavities operating in the strong coupling regime is given in this paper. The strength of the exciton-photon coupling, dynamic optical properties, and relaxation processes along polariton dispersion curves will be discussed, as well as stimulated emission of cavity polariton luminescence.

Opis:
Recent demand for powering small sensors for wireless health monitoring triggered activities in the field of small size efficient energy harvesting devices. We examine energy harvesting in an aluminium beam with a piezoceramic patch subjected to kinematic harmonic excitation and impacts. Due to a mechanical stopper applied, inducing a hardening effect in the spring characteristic of the beam resonator, we observed a broader frequency range for the fairly large power output. Impact nonlinearities caused sensitivity to initial conditions and appearance of multiple solutions. The occurrence of resonant solution associated with impacts increased efficiency of the energy harvesting process.

Another important aspect is to offer a uniform global view on all data which are stored distributed to provide an easy access for users or visualisation tools. Additionally we discus the impact of these uniform access layer on scalability.

Opis:
The Prosopidae is an extinct family, consisting mostly of Mesozoic species. Most probably it accommodates the ancestors of all brachyurans in the large sense. The family appeared in the Late Pliensbachian and disappeared at the Early Palaeocene. Evolution of the Prosopidae, and therefore, brachyuran evolution started on Middle Jurassic, shallow, soft bottom marine environments. The world-wide Callovian transgression made possible the formation of bioherms and reefs in the Late Jurassic, creating ecological niches for the rapidly differentiating prosopids. These crabs migrated rapidly all over Europe in the Oxfordian and began to flourish and massively occupied sponge megafacies from Portugal to Poland. In the Kimmeridgian, the area of known prosopids shrank, which has probably been connected with decreasing of the reef facies. In turn, a Tithonian regression in the per-Tethyan area resulted in changes of habitats and in colonisation of the coral reefs. When reef facies retreated at the Jurassic-Cretaceous boundary, the favourable conditions for crab development also vanished, so the known Cretaceous prosopids are rare and spatially dispersed. In Tertiary, the closely related descendants of them, homolodromiids, inhabited preferably soft muddy bottoms in deeper, colder waters.
Kraby z rodziny Prosopidae, reprezentowane są prawie wyłącznie przez gatunki mezozoiczne. Z filogenetycznego punktu widzenia, są one prawdopodobnie przodkami wszystkich pozostałych gatunków krabów. Przedstawiciele tej rodziny znani są od późnego pliensbachu do wczesnego paleocenu. Ewolucja prosopidów, a poprzez to ewolucja pozostałych krabów, rozpoczęła sią w środkowojurajskich, płytkich środowiskach morskich o miękkim charakterze dna. Ogólnoświatowa transgresja kelowejska stworzyła dogodne warunki do powstania różnorodnych bioherm i raf w późnej jurze, które stanowiły nisze ekologiczne dla szybko różnicujących się dzięki temu krabów z rodziny Prosopidae. Kraby te migrowały gwałtownie na całą Europę w oksfordzie, masowo zasiedlając megafację gąbkową i są obecnie znajdowane w utworach tej facji od Portugalii do Polski. W kimerydzie obszar występowania prosopidów wyraźnie się skurczył, co było prawdopodobnie związane ze stopniowym zanikiem tej facji. Z kolei w tytonie regresja w obszarach perytetydzkich spowodowała zmianę środowiska życia krabów i kolonizację przez nie raf koralowych. Dogodne warunki dla rozwoju tych krabów gwałtownie się pogorszyły blisko granicy jury i kredy (zanikanie facji rafowych) skutkiem czego kredowe prosopidy są rzadkie i geograficznie rozproszone. W trzeciorzędzie najbliżsi potomkowie rodziny Prosopidae - kopalni przedstawiciele rodziny Homolodromiidae - zasiedlili środowiska miękkich den głębszych i zimniejszych mórz.

Opis:
In order to advance modern information technologies, progress in both the fabrication of magnetic nanostructures and of complex materials, from which small magnetic entities - like the skyrmions present in MnSi - emerge and in developing measurement techniques are desired. Here the sensor-based stray field detection using tailor-made micro-Hall magnetometers has proven to be a versatile tool for studying the magnetization reversal of individual magnetic nanostructures, domain wall motion in thin films, as well as the local stray field close to macroscopic samples. In this article we demonstrate that the local stray field can be used to accurately map out the B-T phase diagram of MnSi and serve as a guidance for simultaneously-performed electronic transport measurements. The presented study also serves as a proof-of-principle experiment for future combined investigations of electronic transport and magnetization focusing on electrically-contacted magnetic nanostructures.

Opis:
Productivity enhancement is achievable by increasing the dynamics of machines. This can be accomplished by decreasing the moving mass or by increasing the driving forces. One possibility for increasing the drive forces lies in the use of multiple parallel-acting actuators. Because of the mechanical coupling between the drives, undesirable interference of the actuators occurs. This limits the control bandwidth of the feed axis. Feed axes of machine tools are mostly equipped with linear guides fitted with rolling elements. Since they dispose of just one degree of freedom, small errors in their alignment or thermally induced errors cause constraining loads. In this paper compliant mechanisms are used to mechanically decouple the slide from the guide and drive elements. The application of flexible joints in gantry axes with linear motors and ball screws is investigated. The dynamic behaviour of the feed axis components are modelled using the Finite Element Method. By applying the modal reduction technique, the dynamic behaviour is included in an elastic multibody simulation. With the mechanical decoupling of the drive and guide elements it is possible to increase the control bandwidth of the system. Deviations in motion may also be corrected with parallel-driven feed axis by applying compliant mechanisms.

The paper encompasses the overview of hardware architecture and the systems characteristics of the Fraunhofer driving simulator. First, the requirements of the real-time model and the real-time calculation hardware are defined and discussed in detail. Aspects like transport delay and the parallel computation of complex real-time models are presented. In addition, the interfacing of the models with the simulator system is shown. Two simulator driving tests, including a fully interactive rough terrain driving with a wheeled excavator and a test drive with a passenger car, are set to demonstrate system characteristics. Furthermore, the simulator characteristics of practical significance, such as simulator response time delay, simulator acceleration signal bandwidth obtained from artificial excitation and from the simulator driving test, will be presented and discussed.

Opis:
The e-navigation strategy of the International Maritime Organization (IMO) aims to improve the safety of maritime traffic by increasing cooperation between several maritime stakeholders. The COSINUS (Bolles et al., 2014) project contributes to such a strategy by enabling an automated data exchange (observations, routes and maneuver plans) between ship-side and shore-side navigational systems, developing useful sensor fusion applications upon the new information available from data exchange and introducing new Human Machine Interfaces (HMIs) to support the users of navigation systems. The project shows potential for improvement in maritime traffic safety by ensuring continuous awareness to all participants involved through sensor fusion applications, i.e. by providing all participants (mobile and stationary navigation systems) with a complete view at all times. These applications include detection of critical situations like radar shadowing areas, early and accurate prediction of potential collisions or closest point of approach (CPA) based on the exchanged routes, and improving the accuracy of radars by ensuring high quality data for obstructed or far away routes. The new HMI concepts introduced within the COSINUS project aim at highlighting critical maritime traffic situations. Thus, the users of such navigation systems supported with COSINUS facilities can easily detect such critical situations and react efficiently to avoid collisions, possible crowded areas and inefficient routes.

Opis:
This paper examines the relationship between the media coverage of soccer and political popularity of certain parties during election campaigns which usually followed the world soccer games. The national team’s success on the pitch is related to victory in the political match. This surprising link between the national success in sports and the success in an election for a party or a candidate is explained in the light of Public Mood Theory, founded by W. Rahn, who pointed out that emotions play an important role in political behaviour and national identity, which, in turn, is influenced by the media content, like sports coverage among others. The creation of national identity is mostly built on the national success in sports. Especially in Germany, where soccer is number one sport in media coverage. Sports matches produce winners and losers, thus strongly influencing Public Mood, which is relevant for the formation of political evaluations and judgments, in a democracy shaped by emotions. Sports can shape Public Mood only if they are reported in the media. The analysis of the relationship between interest in soccer and political popularity, presented in the paper, shows how the media coverage of soccer influenced the German political attitudes in 2002, to an extent that it might have been decisive for the election.

Opis:
Large fillet radii are typically found on highly loaded compressor rotors to ensure structural integrity. The objective of this paper is to investigate the impact of such real geometry effects on the flow at the hub section. Investigations were performed numerically for the idealised case of a plane compressor cascade with the 3D Navier-Stokes code TRACE_S. Realistic inlet boundary layer displacement thickness and typical loading levels close to stall are considered at low inlet Mach numbers Ma1 = 0.23. A large fillet with a relative radius of 16% chord length is considered as well as a 3D leading edge bulb-configuration designed at TU Dresden. The results are discussed in terms of iso-Mach surfaces, secondary flow patterns and spanwise incidence and turning. A complex 3D vortex system rises from the fillet radius, which improves the aerodynamic behaviour of the cascade at the end-wall section. With the bulb configuration the suction surface horse-shoe vortex leg was demonstrated to weaken the undesirable cross flow and by that to reduce the hazard of corner stall.

Opis:
In a 4f-3d ferrimagnet the molecular field (a net value expressing the relevant exchange interactions) can be determined from high-field magnetization measurements. If the applied field is high enough, it breaks the ferrimagnetic ground state and drives the system towards ferromagnetic order via non-collinear intermediate phases. Magnetization curves of $Er_2Fe_{17}$ singe crystal were measured along the [100] crystallographic direction in magnetic fields up to 50 T. An unfixed sample, free to rotate, was measured as well. The magnetization measured along the easy magnetization direction shows jumps at 37.5 and 44 T. The first jump was used for the determination of the molecular field (66.4 T). This agrees with the data for the unfixed sample where a kink in the magnetization at 33.5 T yields a molecular field of 65.7 T. The obtained values are in a good agreement with literature data.

Opis:
The electron transport properties and point contact spectra of melt-spun DyCu$\text{}_{5}$ with the cubic phase (structure type AuBe$\text{}_{5}$, space group $F\overline{4}3m$) were investigated. It was found by ac-susceptibility measurements that below a transition temperature T$\text{}_{m}$=6.5 K this phase shows metamagnetism. Between T$\text{}_{m}$ and T$\text{}_{C}$=14.5 K a spontaneous magnetization is found. Our measurements of electrical resistivity confirm the existence of two magnetic phase transitions in the compound. Furthermore, we present point contact spectra of DyCu$\text{}_{5}$-Cu heterocontacts which are directly proportional to the electron-quasiparticle interaction function. Apart from a peak at about 18 meV, which is characteristic of electron-phonon interaction in pure Cu, we observed a series of additional maxima at lower energy, which are connected with the allowed 4f-transitions from the ground state to excited crystalline electric field levels.
