Branding strategies is an important theme in business research. The purpose of the study was to explore how the growing industry of craft brewing are using branding strategies in order to strengthen their brand. The study was based on the theory of Kapferer’s brand identity prism and Keller’s Brand Equity model. The method used to gather data was interviews with several breweries spread across Sweden that were then analyzed using thematic data analysis. The findings show that craft brewer are using branding strategies to a large extent, however, not all the elements of the models are included in their strategy. The findings suggest that the reason for this is that the craft brewing industry is unique due to co-opetition and the nation’s strict regulations on marketing of alcohol. Organizations can use these findings to strengthen their brand as well as get a general understanding of how the industry is using branding strategies. This can be beneficial for newly established craft breweries or breweries that desire a stronger brand.

Title: Understanding Area and Volume Formulae of Geometric Figures in the History of Mathematics and by Pupils Author: Bc. Adela Tavačová Supervisor: prof. RNDr. Ladislav Kvasz, DSc. The aim of this thesis is to describe the nature and possible causes of problematic areas in pupils' understanding of area and volume of geometric shapes and solids and treat this issue from the point of view of its ontogeny and phylogeny. Modern theories of gradual formation of the concepts of area and volume in pupils' minds will be characterized, together with the historical development of these concepts (from ancient Egypt and Greece to modern day). Complex analysis of the current Mathematics course books for primary and lower-secondary level is offered in the second part of the thesis. The analysis is based on the criteria following from the study of academic literature and on the historic research in this area. The aim of the analysis is to describe the way in which the course books treat geometric formulae and to what extent they respect their gradual development. In the final discussion, general aspects leading from the analysis will be summarized and offered as possible inspiration for pupils, teachers and future teachers of Mathematics. Key Words: formula, area, volume, algebraic language, hypothetical...

Ferroelectrics are a group of advanced electronic materialswith a wide variety of properties useful in applications suchas memory devices, resonators and filters, infrared sensors,microelectromechanical systems, and optical waveguides andmodulators. Among the oxide perovskite-structured ferroelectricthin film materials sodium potassium niobate or Na0.5K0.5NbO3(NKN) has recently emerged as one of the most promisingmaterials in microwave applications due to high dielectrictunability and low dielectric loss. This licentiate thesispresents results on growth and structural, optical, andelectrical characterization of Na0.5K0.5NbO3 thin films. Thefilms were deposited by rf-magnetron sputtering of astoichiometric, high density, ceramic Na0.5K0.5NbO3 target ontosingle crystal LaAlO3 and Al2O3, and polycrystalline Pt80Ir20substrates. By x-ray diffractometry, NKN films on c-axisoriented LaAlO3 substrates were found to grow epitaxially,whereas films on hexagonal sapphire and polycrystallinePt80Ir20 substrates were found to be preferentially (00l)oriented. Optical and waveguiding properties of theNa0.5K0.5NbO3/Al2O3 heterostructure were characterized using aprism-coupling technique. Sharp and distinguishable transversemagnetic (TM) and electric (TE) propagation modes wereobserved. The extraordinary and ordinary refractive indiceswere calculated to ne = 2.216±0.003 and no =2.247±0.002 for a 2.0 μm thick film at λ = 632.8nm. This implies a birefringence Δn = ne - no =-0.031±0.003 in the film. The ferroelectric state inNKN/Pt80Ir20 films at room temperature was indicated by apolarization loop with polarization as high as 33.4 μC/cm2at 700 kV/cm, remnant polarization of 9.9 μC/cm2 andcoercive field of 91 kV/cm. Current-voltage characteristics ofvertical Au/NKN/Pt80Ir20 capacitive cells and planar Au/NKN/LaAlO3 interdigital capacitors (IDCs) showed very goodinsulating properties, with the leakage current density for anNKN IDC on the order of 30 nA/cm2 at 400 kV/cm. Rf dielectricspectroscopy demonstrated low loss, low frequency dispersion,and high voltage tunability. At 1 MHz NKN/LaAlO3 showed adissipation factor tan δ of 0.010 and a tunability of 16.5% at 200 kV/cm. For the same structure the frequencydispersion, Δεr, between 1 kHz and 1 MHz was 8.5%. <b>Key words:</b>ferroelectrics, sodium potassium niobates,thin films, rf-magnetron sputtering, waveguiding, refractiveindex, prism coupling, dielectric tunability / NR 20140805

The complementary prism GḠ of a graph G is formed from the disjoint union of G and its complement Ḡ by adding the edges of a perfect matching between the corresponding vertices of G and Ḡ. A set S ⊆ V(G) is a double dominating set of G if for every v ∈ V(G)\S, v is adjacent to at least two vertices of S, and for every w ∈ S, w is adjacent to at least one vertex of S. The double domination number of G is the minimum cardinality of a double dominating set of G. We begin by determining the double domination number of complementary prisms of paths and cycles. Then we characterize the graphs G whose complementary prisms have small double domination numbers. Finally, we establish lower and upper bounds on the double domination number of GḠ and show that all values between these bounds are attainable.

The complementary prism GḠ of a graph G is formed from the disjoint union of G and its complement G by adding the edges of a perfect matching between the corresponding vertices of G and Ḡ. A set S ⊆ V(G) is a restrained dominating set of G if for every v € V(G) \S, v is adjacent to a vertex in S and a vertex in V(G) \S. The restrained domination number of G is the minimum cardinality of a restrained dominating set of G. We study restrained domination of complementary prisms. In particular, we establish lower and upper bounds on the restrained domination number of GḠ, show that the restrained domination number can be attained for all values between these bounds, and characterize the graphs which attain the lower bound.

The main objective of this bachelor thesis was to gain awareness of accuracy and precision in total station measurements. Experiments were designed, executed and analyzed.   The approach to the subject was to examine measurements made with various prism set-ups. Prisms are supposed to be directed to the total station with the front face in the line of sight. In the experiment the prisms were directed in various angles in order to measure in non-perfect measuring arrangement and the behavior of the precision and accuracy were noted.   The mean values and standard uncertainties were calculated from the material as well as RMS Error in the cases where reference values could be used as true values. The reference values for comparison were available due to the possibility to use a test field – a network of concrete pillars with well-defined coordinates.   To see whether the precision (the standard uncertainty) changed between a measurement sample made with correctly positioned prisms and a measurement sample towards the angled prisms, a statistical test method was used. (The test method is recommended in the international standard ISO 17123-1; Optics and optical instruments, Field procedures for testing geodetic and surveying instruments, Part 1: Theory).   The results from the experiments showed that there were larger standard uncertainties in the slope distance measurements towards extreme angled prisms than to correctly directed prisms. Surprisingly it was also larger standard uncertainty in vertical angle measurements toward correctly directed prisms than slightly angled prisms. The mean values of the horizontal angle measurement drifted sideways in the measurements made towards one extreme angle to the opposite extreme so that a total shift of around one centimeter was detected at short distances as well as up to 100 m distance.    When aiming in between the separate prisms of 360-degree targets the standard uncertainty were larger in horizontal angle measurements at a few occasions where it seemed like the autolock function had chosen two different prisms to lock on to, at separate occasions. The standard uncertainties were also larger in all vertical angle measurements when aiming in between the prisms.   The results showed clearly that even when the standard uncertainties of the measurements were of equal size, the mean values – when measuring in the different test positions – could vary substantially. / Huvudsyftet med detta kandidatarbete var att öka medvetenheten angående noggrannhet och precision i mätningar utförda av en totalstation. Ett antal experiment planerades, genomfördes och analyserades.   De områden som undersöktes i projektet var hur mätningarna påverkades av olika sätt att vinkla prismor mot totalstationen. Det rekommenderas att rikta ett prismas framsida mot totalstationens siktlinje. I experimentet vinklades prismorna i olika lägen för att mätningar skulle utföras i icke-perfekta förhållanden.   Medelvärden och standardosäkerheter beräknades ur mätdatan samt RMSE i de fall där det fanns referensvärden att jämföra med. Dessa referensvärden var tillgängliga tack vare möjligheten att få utnyttja ett testfält med betongpelare med kända koordinater.   För att utröna om precisionen (standardosäkerheten) ändrades mellan mätningar på korrekt inriktade prismor och de mätningar som gjordes mot vinklade prismor, utfördes ett statistiskt test. (Testmetoden rekommenderas i den internationella standarden ISO 17123-1, Optics and optical instruments - Field procedures for testing geodetic and surveying instruments - Part 1: Theory).   Resultaten av undersökningarna visade att där var större standardosäkerheter i mätningar av den lutande längden när prismorna var extremt vinklade än när de var korrekt orienterade. Standardosäkerheten var något överraskande också större med korrekt riktade prismor i vertikalvinkel-mätningarna med autolockfunktionen än om prismorna var något utåtvinklade. Medelvärdena på horisontalvinklarna drev sidleds i mätningar gjorda i en extrem vinkelposition till den motsatta extremen så att en total förflyttning på runt en centimeter konstaterades på korta avstånd likväl som på avstånd upp till 100 m.   Vid inriktning av siktet mot områdena mellan de separata prismorna i 360-gradsmålen så ökade standardosäkerheten i horisontalvinkel vid ett par positioner då det verkade som att autolockfunktionen valde båda prismorna på var sida, vid olika tillfällen. Standardosäkerheten var också större vid samtliga vertikalvinkelmätningar mot områdena mellan prismorna.   Resultaten visade tydligt att även om standardosäkerheterna i mätningarna var i samma storleks-ordning så kunde medelvärdena av mätstorheten mellan de olika testpositionerna variera substantiellt.

Indiana University-Purdue University Indianapolis (IUPUI) / Fibromyalgia Syndrome (FMS) is a chronic, painful rheumatic condition characterized by recurrent musculoskeletal pain, fatigue, and nonrestorative sleep, for which there is currently no biological marker. People who suffer from fibromyalgia are extremely susceptible to the effects of psychological stressors which may in turn exacerbate the symptoms of the disease. As unrelenting pain is the main symptom of fibromyalgia, it follows that patients would experience personal losses and changes in their self-schemas or the way in which they view themselves as a result. This study was particularly focused on identifying the enmeshment of self-schemas and pain-schemas, and the extent to which women with fibromyalgia experience pain and self-schema enmeshment (PSSE). Additionally, this study sought to determine the utility of using the Implicit Association Test as a measure of PSSE. The present study compared FMS patients to a group of diabetes patients on several measures of schema enmeshment, including the IAT. It was hypothesized that the two disease groups would differ significantly on the level of PSSE indicated by the IAT, and the two disease groups would not differ on enmeshment with illness indicated by the IAT. Additionally it was hypothesized that the IAT would be correlated with explicit measures of PSSE. Results did not support either of these hypotheses; however the sample size and statistical power necessary to test these hypotheses was severely lacking and thus they could not be evaluated in an appropriate manner. Results did not support the hypothesis that the IAT would be highly correlated with the explicit measures of PSSE. Based on these results and the existing literature, it is still somewhat unclear as to whether or not the IAT would be an acceptable/feasible tool in assessing PSSE in fibromyalgia patients.

Let G be a graph and G̅ be the complement of G. The complementary prism GG̅ of G is the graph formed from the disjoint union of G and G̅ by adding the edges of a perfect matching between the corresponding vertices of G and G̅. For example, if G is a 5-cycle, then GG̅ is the Petersen graph. In this paper we investigate independent domination in complementary prisms.
