We consider the Whitham equation u t +2uu x +Lu x =0, where L is the nonlocal Fourier multiplier operator given by the symbol m(ξ)=tanhξ/ξ. G. B. Whitham conjectured that for this equation there would be a highest, cusped, travelling-wave solution. We find this wave as a limiting case at the end of the main bifurcation curve of P-periodic solutions, and give several qualitative properties of
Background and purpose — Pooling data of studies evaluating total knee arthroplasty migration using radiostereometric analysis (RSA) may be compromised when the RSA method used would influence estimated differences between groups. We therefore reanalyzed a marker-based RSA study with model-based RSA to assess possible limitations of each RSA method, including insert micromotions in modular TKA and
The Aviation industry is ultra-safe. Rules and procedures have been attributed as a contributory factor for attaining this high level of safety. The complexity of the aviation system has risen dramatically in the last few decades due to the development and introduction of modern aircraft and on-board technological innovations. Every day pilots encounter situations they did not expect. During those
This project aims to propose an alternative memory architecture that allows space for a society to process and heal after having experienced collective trauma. The project site and setting is my mother’s home country Chile where the military coup in 1973 and the following dictatorship is still a source of grief and conflict. The point of departure for the project is the concept of architecture
Effects of carbon functionalization on the catalytic properties of the space underneath epitaxial graphene flakes on Ir(111) are investigated with Ambient Pressure X-ray Photoelectron Spectroscopy studies of oxygen hydrogenation. The 0.1 mbar oxygen atmosphere hosting O-intercalated graphene flakes was replaced with hydrogen pulses lasting 50 s each, triggering the water formation. Underneath prisChemical reactions confined to near atomic scales have many hypothesized applications. The demand for ever smaller electronical components with superior electric properties for example requires atoms to group in specific shapes that can only be cast in confined spaces. Biological cells are an example of confined reactions in the nature. Hence, in order to recreate those processes, to develop bette
Flann O´Briens The Third Policeman är skriven 1940 men publicerades 1967, efter författarens död. Några av de narrativa grepp som används i berättelsen undersöks. Tidsordningen i berättelsen jämförs med tidsordningen i den berättade storyn med utgångspunkt från teori i Gérard Genettes Narrative Discourse-An Essay in Method. Den totala tidens varaktighet (duration) i berättelsen jämförs med den tot
This report is made in order to evaluate the safety, in case of a fire, of personnel and patients in the surgical facilities at Helsingborg General Hospital. The problem that arises in this report is regarding the evacuation of patients that are undergoing surgery. This is a problem since it can take up to 60 minutes to finish a surgery and make a patient ready for evacuation. To determine the fir
Property rights systems and their relationship to the informal spaces are a contested and highly relevant part of contemporary development discourse. This study explores the reproduction of the concept of the informal in urban space. The central problematic of this study then departs by asking in what ways does the debate on property rights and the informal economy emerge as a representation of sp
Costa Rica has an important banana-producing industry that requires vast amounts of pesticides. These can leak into the environment and cause health effects. The most widely used pesticide is mancozeb, which is rapidly degraded to the carcinogenic and potentially groundwater-contaminating metabolite ETU. This study was executed in Matina, one of the most densely banana-cultivated areas of Costa Ri
The technological field can be seen as a huge advance for mankind before it emerged employers had to hire experts located in the same geographical area as the company. This changed with the introduction of information and communication technologies. Because of this, the labor market was able to become more global, meaning that employers do not need to hire employees who are physically close to the
Uppsatsen syfte är att undersöka om de svenska restriktionerna under co-vid-19 pandemin var tillåtna enligt religionsfriheten i artikel 9 i den euro-peiska konventionen om de mänskliga rättigheterna och religionsfriheten i regeringsformen. Religionsfriheten är absolut i regeringsformen men de delar som utgör utlopp av andra friheter, exempelvis mötesfriheten, får begränsas på samma sätt som de friThe essay aims to examine whether the restrictions posed during the covid-19-pandemic was legitimate in accordance with the freedom of religion posed in the European Convention on the Human Rights and the freedom of religion as stated in the Instrument of Government. The freedom of religion stated in the Instrument of Government is absolute and cannot be restricted. What is seen as use of other fr
Bostäder i storstäder har blivit en svårtillgänglig lyxvara, samtidigt som ett fåtal tjänar mycket pengar på situationen. Som bostadsmarknaden ser ut idag, med vinstdrivande byggbolag tillsammans med dyr mark, går problemet inte att lösa utan förändring (Länsstyrelsen 2021). Detta examensarbete söker efter ett alternativt sätt att bo där de boende tillsammans tar kontroll över sin boendesituation.Housing in big cities has become a luxury that many people cannot afford, while a few make a lot of money out of the situation. As the housing market stands today, with profit-driven construction companies and expensive land, the problem cannot be solved without change (Länsstyrelsen 2021). This thesis seeks an alternative way of living, where the residents together take control of their housing s
Detta examensarbete utforskar det relativt outforskade fenomenet venture studios (även känt som bolagsbyggare, venture builders och startup studios), vilka är företag som systematiskt bygger bolag. Trots att antalet venture studios ökar så är akademisk forskning kring ämnet relativt begränsad. Denna studie syftar till att fylla denna kunskapslucka genom att genomföra en fallstudie på sex svenska vThis master's thesis explores the relatively unexplored phenomenon of venture studios (also known as venture builders or startup studios), which are companies that systematically and concurrently build startups. Despite their growing popularity, the academic literature on how venture studios operate is still limited and no structured and extensive description of the business model appears to e
Änkekejsarinnan Cixi styrde Kina under kejsardömets sista halvsekel. Hon utmålades länge som maktgalen och grym, men på senare tid har en mer nyanserad bild presenterats. I den här uppsatsen analyseras hur ett antal händelser i Cixis liv i relation till Guangxu-kejsaren och hans konkubin Zhenfei har beskrivits i olika källor. Syftet är att se vad dessa händelser säger om Cixi som person och om detEmpress Dowager Cixi governed China during the final five decades of the Qing dynasty. She was for many years depicted as a cruel megalomaniac, lately Cixi has been described in a more nuanced way. This paper seeks to analyze how a selection of sources describe a number of specific events in connection with Cixi and the Guangxu-emperor and his concubine Zhenfei. The objective is to discuss what th
En kvalitativ fallstudie där vi med hjälp av öppna personliga intervjuer talat med folk i ledande befattningar på vår fallkoncern Elektrokoppargruppen för att forma oss en bild av hur budgeten fungerar på företaget. Utifrån valda teorier om budget och dess process har vi sedan analyserat företaget och dess situation. Utav budgetprocessens tre delar har vi kommit fram till att budget är ett effekti
