The Theory of Characteristic Modes (TCM) has been applied to design high-performance MIMO antennas for mobile terminals. However, existing studies focus on free-space (FS) performance, which is mostly irrelevant in real usage. This paper investigates the performances of two TCM-based MIMO terminal antenna designs in 7 realistic user scenarios for frequencies below 1 GHz. Full-wave simulation resul

Version 3 av ecoinvent är den första databasen att erbjuda möjligheten att koppla samman livscykelinventeringar (LCI) utefter olika länkningsalgoritmer. Genom dessa länkningsalgoritmer tar ecoinvent nu fram bakgrundslivscykelinventeringar med både medeldata och långsiktig marginaldata (t.ex. över elmarknader i olika länder). Idealt sett representerar långsiktig marginaldata över elmarknader den ytVersion 3 of the ecoinvent database is the first background database to offer the possibility to link life cycle inventories (LCI) according to different linking algorithms. Using those algorithms, ecoinvent now provides both average and long-term, marginal background LCI data, (e.g. for electricity markets for different countries). Long-term, marginal data for electricity markets ideally represen

Den allvarliga brottsligheten som begås av kriminella nätverk har ökat drastiskt under de senaste åren. Skjutningar och sprängningar har blivit alltmer förekommande och diskuteras frekvent i medier och politiska debatter. Hur man ska komma till rätta med problemet är en angelägen fråga. Ett av förslagen, för att ge de brottsutredande myndigheterna effektivare verktyg för att förhindra denna typ avSerious crimes committed by criminal networks have increased over the last couple of years. Shootings and explosions have become more common and are frequently discussed in media and political debates. How to solve this problem is an important question and a proposal that has been suggested, with the purpose to give criminal investigation authorities more effective tools to prevent these serious c

Självskadebeteende är ett alltmer vanligt förekommande fenomen bland unga och vård är i många fall essentiellt för att lindra problemet. Självskadebeteende kan uttrycka sig på olika vis, bland annat genom att den unge medvetet utsätter sig för riskfyllda sexuella situationer. Syftet med uppsatsen är att med rättsdogmatisk metod undersöka när självdestruktivt sex utgör en grund för vård enligt Self-harm is a growing problem in our society, especially among adolescents. The purpose of this essay is to investigate under which circumstances selfdestructive sex can be considered a reason for compulsory care according to 3 § Care of Young Persons Act, LVU. The current legal conditions will be explored as well as case law. Compulsory care is intended to provide help to young people whose

Nocturnal hypoglycemia is a common and potentially very dangerous condition facing persons with insulin-treated diabetes. To reduce the risk of going low while sleeping, many patient wilfully elevate their glucose level before bedtime, thereby also eroding the conditions for a sound glucose control for the next day. Recent advances in sensor technology allow for real-time frequent monitoring of th

Combining attribute grammars with object-oriented programming supports a new kind of declarative programming, allowing compilers to be built in a highly extensible manner. By leveraging a base compiler, extended languages can be supported at a relatively low cost. Recent work shows the applicability of the technique to general-purpose programming languages like Java. In this article, we illustrate

Correlation coefficient of received signals across a pair of antennas is a key performance indicator for multiple-input multiple-output (MIMO) systems. For multipath environments with uniform 3D angular power spectrum, the signal correlation between two antennas can be exactly calculated from their 3D radiation patterns. When radiation patterns are unavailable, a simplified approach that only requ

Using the metric of channel capacity, three dual-antenna multiple-input multiple-output (MIMO) terminals with adaptive impedance matching were evaluated at LTE Band 13 in four different user scenarios using simulation. Each of the three terminals is equipped with a slot-monopole antenna and a planar inverted-F antenna (PIFA). The slot monopole is fixed at one edge of the chassis, whereas the locat

Model-based systems in control are a means to utilize efficiently human knowledge and achieve high performance. While models consisting of formalized knowledge are used during the engineering step, running systems usually do not contain a high-level, symbolic representation of the control and most of its properties, typically named numerical parameters. On a system level and beyond the plant data,

Abstract in UndeterminedMultiple-antenna handheld terminals are an integral part of the latest mobile communication systems, due to the adoption of multiple-input multiple-output (MIMO) technology. In this contribution, MIMO performances of three multiple-antenna configurations for smart phones are investigated in an urban macrocellular environment, based on an extensive MIMO measurement campaign

Truncated correlation and convolution operators is a general operator-class containing popular operators such as Toeplitz (Wiener-Hopf), Hankel and finite interval convolution operators as well as small and big Hankel operators in several variables. We completely characterize the symbols for which such operators have finite rank, and develop methods for determining the rank in concrete cases. Such

Sedan införandet av det kommunala planmonopolet 1947 till följd av den bostadssociala utredningen har planlagstiftningen reformerats flertalet gånger. I förevarande examensarbete studeras den historiska utvecklingen av både det kommunala planmonopolet och dess tillhörande planlagstiftning. Examensarbetet syftar till att studera hur det kommunala planmonopolet kommit att utvecklas och om reformerSince the introduction of the municipal planning monopoly in 1947 following the Housing Social Investigation, the planning legislation has been reformed several times. In this thesis, the historical development of both the municipal planning monopoly and its associated planning legislation is studied. The aim of the thesis is to examine how the municipal planning monopoly has evolved and whether

Allvarlig brottslighet som begås inom kriminella nätverk har ökat drastiskt under senare år. Skjutningar och sprängningar har blivit alltmer förekommande och nu diskuteras även finansierandet av skjutvåldet genom narkotika-, smugglings- och ekonomisk brottslighet i politiska debatter. Hur man ska komma till rätta med problemet, med hänsyn till förbättrade tekniska förutsättningar och tystnadskultuSerious crimes committed within criminal networks have increased drastically in recent years. Shootings and explosions are unusually often occurring in Sweden and now the financing of this deadly violence by drug, smuggling and financial crimes is also discussed in political debates. How to effectively deal with the problem, despite improved technology and a culture of silence in criminal gangs, i

Many ships today rely on Global Navigation Satellite System (GNSS), for their navigation, where GPS (Global Positioning System) is the most well known. Unfortunately, the GNSS systems make the ships dependent on external systems, which can be malfunctioning, be jammed or be spoofed. There are today some proposed techniques where, e.g. bottom depth measurements are compared with known maps using Ba

Bosonic strings can be discretized in terms of dynamically triangulatedrandom surfaces. We investigate the possibility of introducing fermionicdegrees of freedom on the surface in terms of Ising spins, which in twodimensions correspond to Majorana fermions. Critical properties of themodel are estimated using finite-size scaling methods.

An estimation model which uses the gross heat release data and the fuel energy to estimate the total amount of emissions and unburned Hydro Carbon (HC) is developed. Gross heat release data is calculated from a self-tuned heat release method which uses in-cylinder pressure data for computing the energy released during combustion. The method takes all heat and mass losses into account. The method e
