The reassignment method is a technique for improving the concentration of signals in spectrograms and other time-frequency representations (TFR). It achieves this by displacing the points in a TFR according to the reassignment vector for every point. By doing so, the reassignment method gives perfect concentration of infinite constant frequency sinusoids, impulses and linear chirps. A downside to
The Chinese urban population face serious health issues due to the increasing concentration of air pollutants. Research has shown that air quality was influenced by urban forms, and that special combinations of city characteristics could contribute to sustainable urban development. This study aims to determine how urban forms affected air quality in Chinese cities. In this context, urban forms are
Empirical evidence for the growth effects of the concepts of related- and unrelated variety have been inconclusive since the introduction in 2007. This thesis contributes to the field by suggesting how the concepts of related- and unrelated variety may be moderated by the absorptive capacity found in a region. Absorptive capacity is suggested to work as a diffusion mechanism in relation to related
I föreliggande uppsats studeras hur sex transsexuella män skapar och framställer sin maskulinitet på Youtube. Youtube har kommit att bli en plattform som används av många transsexuella personer. Tidigare forskning har visat på hur Youtube fungerar som en självuppfyllande process där transsexuella personer legitimerar och uppnår en bekräftelse för vilka de är (Jones 2019, Horak 2014). I dessa video
The purpose of this thesis is to explore the motivations of young people for manifesting their consumption behavior through Instagram stories. Additionally, the purpose includes gaining an understanding of the way consumption behavior is portrayed.
In this paper we discuss methods to estimate a monotone frequency of species in a population when the ordering of species is unknown. The question arises from [5], where the case of known order was taken into account, and the method is inspired by [2]. We discuss first a regression approach that however only leads to the trivial solution, and then a likelihood approach that allows some generali- s
The contemporary job advertisement is characterized by enhancing organizational attributes that are perceived as desirable. To what extent this evaluative way of writing advertisements affects job seekers perception of organizations is an area that requires more attention within research. How individuals subjectively feel that they will fit with an organizational context is referred to as Person-O
The global demand for fresh food has increased during the past five years and the demand is anticipated to continue growing in the future. The consumers' expectations are also getting higher and higher, which is why it is of great importance that the actors within the food industry meet these requirements to remain competitive. Fresh food is perishable goods which have a short shelf life. The
While flying today the customers will receive static advertisements on the screens placed in front of every seat. Hence, the advertisements do not differ depending on the flight’s duration or personal interests. Our goal was to develop a marketing tool where the marketing team at different airlines could specify under which circumstances a certain advertisement would be displayed onboard. The desi
Introduction: Knowing diffusion coefficients in supercritical carbon dioxide is important from an efficient process in chromatography and extraction. Background: Several papers have estimated diffusion coefficients in pure supercritical carbon dioxide, but rather few have investigated the effect of adding a cosolvent. Aim(s): Building and validating a system for estimating diffusion coefficients
Världen som vi känner den hålls samman av fyra grundläggande krafter. Gravitationskraften drar oss mot jorden och håller samman planeter, stjärnor och galaxer. Den elektromagnetiska kraften styr i princip allt annat vi upplever i vår vardag. Den starka kärnkraften håller samman protoner och neutroner i atomkärnor och binder de kvarkar som i sin tur bygger upp dessa partiklar, och den svaga kärnkraWe present a generalisation of the flavour-ordering method applied to the chiral nonlinear sigma model with any number of flavours. We use an extended Lagrangian with terms containing any number of derivatives, organised in a power-counting hierarchy. The method allows diagrammatic computations at tree-level with any number of legs at any order in the power-counting. Using an automated implementat
Under the Family Planning Policy, the contraceptive use in China is not only the outcome of personal choice but highly influenced by the policy regulations. Using provincial level data, this study aims in finding to what extend does Family Planning Policy have its impact on the contraceptive use of married Chinese women aged 15-49 years from year 1992 to 2017. Controls for social economic status (
The animosities between India and Pakistan have been continuous since partition of British India over seven decades ago. Disputes over Kashmir and the rivers flowing through the region can be said to represent a nucleus of the tensions between the two countries. Due to environmental stress and population growth, hydropolitics is persistently being set under pressure. Three security frames, nationa
This thesis seeks to explain constraining effects of distance to markets on agricultural smallholder’s ability to commercialise, using Zambia as a case. Despite a growing consensus that inaccessible markets constrain the development of broad-based agricultural growth, creating socio-economic regional disparities, the exact nature by which distance and market access interact with agricultural produ
In 2011, the Dutch dredging company Van Oord was hired to expand the Suape port’s capacity by dredging the entrance to a new shipyard, and to deepen the access channel to the port in order to allow bigger tankers to reach a newly built local oil refinery. The company took out insurance for these projects by the Dutch ECA Atradius DSB (Dutch State Business). These projects ended up having major imp
The dairy industry has a noteworthy environmental footprint, specifically on global warming and resource depletion. Yet, environmental challenges also adversely impact the sustenance of many dairy value chain stakeholders. This is problematic not only in terms of livelihood for more than 70 million rural households but also considering the growing population and hence the increasing dairy demand.
