Nonlinear propagation of electromagnetic waves is an important problem in optics. Often the properties of the nonlinear media are not fully understood. The solution of an inverse problem can provide an aid to that understanding. An inverse transmission problem is posed, it is one of reconstructing the medium parameters, by measurement of a wave that has been propagated through the nonlinear medium
This paper studies regional museum, archives and arts education commissions of the Region of Scania, reformed in 2009, from a policy analysis perspective. It describes the background, design and implementation of the new policy and analyses its effects. The paper gives detailed information on the complexities of policy tool design and implementation, and discusses it in the light of regional gover
The aim of this study is to systematically compare parametric and non-parametric techniques for analyzing trends in annual NDVI derived from NOAA AVHRR sensor in order to examine how trend type and departure from normality assumptions affect the accuracy of detecting long-term change. To generate annual data, the mean NDVI of a four-month long ‘green’ season was computed for fifteen sites (located
We report the improvements made to our previously developed electrochemical cantilever (EC) sensor, where nanoporous gold material is employed as working electrodes in microcantilever arrays, while combined counter-reference electrodes are integrated on the chip. For a surface stress change of 1mN/m induced on the microcantilever, the cantilever deflects is 7.3 nm at the free end, indicating high
Hadfield steel is widely used in heavy-duty applications involving high impact loads and abrasive wear, such as mining and stone crushing equipment, due to its high toughness, ductility, and work-hardening ability. However, the as-cast microstructure contains carbide precipitation and chemical segregation, particularly along grain boundaries, which causes embrittlement and reduce service performan
Early Warning Systems (EWS) are crucial for safeguarding communities, but are vulnerable to failure due to a technocratic focus that excludes local communities. This thesis closes the gap between normative participatory principles and practical implementation by exploring the entry points or challenges that affect community participation. Adopting a complexity theory lens, the study conducts a qua
Komplex mjukvara kräver testning på flera nivåer. Detta examensarbete undersöker automatiserad testning av Radio Block Centre (RBC). En RBC bestämmer hur långt ett tåg får köra och i vilken hastighet. Examensarbetet har tre fokusområden. Det första området undersöker hur nuvarande testscript kan göras mer dynamiska genom att införa slumpmässighet. Slumpmässighet införs genom att variera tåglängd. Complex software must be tested carefully. This thesis looks at how automated testing can be improved for Alstom’s Radio Block Centre, a system that supervises trains and sends movement authorities. The work focuses on three practical ways to improve an existing automated test setup. First, it studies how the test suite can be made more dynamic by introducing randomness into current test scripts.
This study presents a modular approach for the synthesis of multifunctional affinity sorbents, facilitating molecular separation via magnetic molecularly imprinted polymers. A magnetic propranolol-imprinted polymer (MIP) nanocomposite with superparamagnetic characteristics was synthesized through precipitation polymerization process coupled with coprecipitation methods. Initially, the propranolol-
OBJECTIVES: Implementation of the Stroke Action Plan for Europe (2018-2030) (SAP-E) was initiated in 2019. It is now updated at mid-term to reflect and respond to challenges for stroke care in Europe in 2025. METHODS: The SAP-E covers the entire chain of stroke care. The sections (state of the art, current status and targets) were developed by working groups and finalised based on inputs from the
