We consider channel estimation (CE) in narrowband Internet-of-Things (NB-IoT) systems. Due to the fluctuations in phase within receiver and transmitter oscillators, and also the residual frequency offset (FO) caused by discontinuous receiving of repetition coded transmit data-blocks, random phase noises are presented in received signals. Although the coherent-time of fading channel can be assumed
This issue of the AILA Review focuses on transdisciplinarity as the key to developing shared languages in and across domains and professional settings. The relationship and collaboration between researchers and practitioners have long been discussed within and across applied sciences and theoretical disciplines, mainly in the framework of transdisciplinarity (see AILA Review 31, 2018, for a recent
The building blocks of Titan and Enceladus are believed to have formed in a late-stage circumplanetary disk (CPD) around Saturn. Evaluating the evolution of the abundances of volatile species in this disk as a function of the migration, growth, and evaporation of icy grains is then of primary importance to assess the origin of the material that eventually formed these two moons. Here we use a simp
Vascular age is determined by functional and structural changes in the arterial wall. When measured by its proxy, pulse wave velocity, it has been shown to predict cardiovascular and total mortality. Disconcordance between chronological and vascular age might represent better or worse vascular health. Cell senescence is caused by oxidative stress and sustained cell replication. Senescent cells acq
Transitioning to net-zero carbon emissions requires phasing-out unabated coal power; however, recently it has only been declining in some countries, while it stagnated or even increased in others. Where and under what circumstances, has coal capacity reached its peak and begun to decline? We address this question with an empirical analysis of coal capacity in 56 countries, accounting for 99% of co
Walsh's A Theory Of Magnitude (ATOM) contends that we represent magnitudes such as number, space, time and luminance on a shared metric, such that “more” of one leads to the perception of “more” of the other (e.g. Walsh, 2003). In support of ATOM, participants have been shown to judge intervals between stimuli that are more discrepant in luminance as having a longer duration than intervals between
The societal interest for a more sustainable and circular food production is increasing. Hydroponic farming is an alternative way of growing vegetables that can bring farming into urban environments, reducing long transports of food. In parallel, the focus in waste treatment is being more directed toward resource recovery. Food waste is used as a resource for biogas production, producing a liquid
The last decades, far-right political parties made huge advancements in divisive elections in the West with growing anti-refugee and anti-Islam sentiments. There is no doubt that policies in Sweden have emboldened the far-right. The real question is how does this affect the already established lives of children of immigrants that come from a different culture? The purpose of this study is two-fold
Organized crime is generally associated with men. Women in organized crime have long lived under the radar, and it is only in recent years that their participation has begun to be noticed. The aim of this qualitative study (based on feminist IR theory) is to provide understanding on how women in Sweden are involved in organized crime, what roles they play, and how they are discursively represented
In this project, I wish to take a glance at what WiFi routers can do in the future. The new solution could make the current WiFi routers have more physical meaning which can impact our real life while providing indispensable wifi signals. Besides offering WiFi signals, WiFi routers adopted with FTTR all-optical networking solutions can control and monitor all the IoT smart devices connected to the
Sweden has a long history of colonialism in the Sápmi region where the state repeatedly has claimed land at the expense of reindeer husbandry and the Sami culture. The Swedish government has never recognized its colonial history and is still today claiming land for various projects, often covered by wording about sustainable development and a green transition. The purpose of this thesis has been t
Digitaliseringen har i stor utsträckning revolutionerat sättet som företagen gör affärer på. Det finns inte längre samma behov av fysiska platser för affärsverksamheter eftersom teknologin har skapat virtuella platser där företag kan sälja både varor och tjänster utan att överhuvudtaget sätta en fot i jurisdiktionen. Emellertid har reglerna om fast driftställe alltsedan 1920-talet präglats av att
In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. Many scholars believe that Quantum technology will
This study examines if there are positive effects of constructing portfolios based on value and momentum. Three value portfolios (low, medium, high) and three momentum portfolios are constructed using large cap stocks from the four Nordic Nasdaq OMX exchanges. The portfolios are then re-sorted on an annual basis over the test period 2005-2016. Furthermore, two long-short market neutral portfolios
Climate change and biodiversity loss present critical challenges for humanity, yet biodiversity often remains overlooked in corporate sustainability strategies. This study, conducted within Schneider Electric’s environ- mental team, aims to address this gap by comparing the carbon intensity and biodiversity impacts of new production processes for aluminum and steel against conventional methods. Ut
According to Ronald Inglehart, level of individual’s environmental concern is linked with grade of post-materialism resulting from physical and economic security experienced. As post-materialist individuals are considered to prioritize environmental protection over economic benefit, this study raises a question whether this change in values can provide a long-lasting solution for environmental cha
Hur förhåller sig vinstsyftet till målet om hållbar utveckling? I denna uppsats utreds vad det aktiebolagsrättsliga vinstsyftet innebär utifrån 3 kap. 3§ ABL och hur det förhåller sig till ekonomiska begrepp som CSR (Corporate Social Responsibility) och negativa externaliteter. Uppsatsen syftar också till att undersöka hur gällande lagstiftning eventuellt kan vidareutvecklas för att företag ska taHow does the profit motive to the goal of sustainable development? This study analyzes what the corporate law profit objective means on the basis of Chapter 3. Section 3 ABL and how it relates to economic concepts like CSR (Corporate Social Responsibility) and negative externalities. The essay also aims to examine how the current legislation may be developed for businesses to take greater social r

Topic/course: NEKM01 Master thesis Author: Anna Persdotter Supervisor: Fredrik NG Andersson Keywords: Export, Comparative advantage, China, Sweden, the United States, Engle Granger, ECM Purpose: The purpose of this thesis is to examin
A solution to an ordinary differential equation may be stable or unstable. Let x = φ(t) be a solution of an autonomous differential equation x′ = Ax. The solution x = φ(t) with φ(0) = t0 is stable if every other solution ψ(t) with initial condition sufficiently close to φ(t) will remain close to φ(t) for all t > 0. For an autonomous system of linear differential equations, it is possible to determ
