Characteristic Mode analysis is a widely used technique in antenna design, providing insight into the fundamental electromagnetic behavior of radiating structures. In this paper, we establish fundamental bounds on the slope of characteristic mode eigenvalues and angles, demonstrating that their rate of change is subject to fundamental constraints for all possible realizations within a given design
Since the Lisbon Treaty’s entering into force in 2009 it is stated in Article 6(2) TEU that the EU shall accede to the European Convention for the Protection of Fundamental Rights (ECHR). In the second sentence of the same article it is provided that “such accession shall not affect the Union’s competences as defined in the Treaties”. Attached to the Lisbon Treaty is also Protocol No 8 in which it
Constructing dam is a possible solution for remitting the scarcity of irrigation water resource in Bortala, Northwest China. Considering the complexity of dam site selection, Analytic Hierarchy Process (AHP) was chosen in combination of Geographic Information System (GIS) as the method of Multi-Criteria Decision Making on selecting dam site. Precipitation, slope, geological layer, soil type, land
Sustainable development is now a part of environmental, social, and economic agendas all over the world. Sustainability projects are cropping up in urban areas, including projects in the housing sector aimed at sustainable regeneration. Simultaneously, it is now recognized that public participation is an essential character of implementing change. And within sustainability participation, it is con
The primary purpose to this study was to explore the role of local government in Sweden, primarily through the eyes of some of the people working within one. Consideration of some of the structural characteristics of local government in Sweden, in particular the privileges and responsibilities accorded to local municipalities there and in what context, lead the author to conclude that Swedish muni
The purpose of this Bachelor thesis is to investigate and explain an ongoing process on the Swedish book- and publishing-market as a result of the new alternative ways of publishing. The investigation concerns questions about what need the electronic publishing fills for the authors compared to traditional publishing, and what happens to the writer’s role when published digitally on self-publishin
Teachers’ experiences of school leadership behaviour and the social contexts in which these have taken place interest me. I aim to identify and understand what Swedish secondary school language teachers’ reflections are on what they require in terms of leadership from their principals in different contexts in order to gain personal job satisfaction. The objective is that this research can then fun
Participation of Civil Society Organisations (CSOs) has been greatly promoted by the European Union (EU) and many CSOs in social policy sphere in particular have increasingly gained their participatory venues and consultative status vis-a-vis EU institutions since the 90’s. However, their expected role to bring even the most marginalised groups’ voice into European policy making process poses a qu
I detta arbete har en Minimum viable product (MVP) för en applikation utvecklats, som gör det säkrare att avveckla och ta bort endpoints för ett REST API. Tidigare arbete har visat att hanteringen av avvecklingen av endpoints i REST API:er är ett problem, där REST API:er inte följer protokoll för avveckling och borttagning. Applikationen är gjord för att tillhandahålla ett enkelt sätt att övervakaIn this thesis - a Minimum viable product (MVP) for an application aimed at making deprecation and removal of REST API endpoints safer - was developed. Previous work has shown that handling deprecations and removal of endpoints in REST APIs is a problem, with REST APIs not following deprecation-removal protocols nor giving the API consumers the information needed to properly update their software.
Inconel 718 is a widely used Nickel-based alloy in the aerospace sector. However, its exceptional mechanical properties make it a very difficult material for machining operations. Additive manufacturing presents itself as a promising alternative, as it would reduce the need for post-printing material removal by machining. However, not enough research has been done about the behaviour of this mater

A model is used to describe a system physically or mathematically and to give information about changes in the system variables. Physical knowledge about the system and its quantities can be useful to build a physical model obeying the laws of nature. However, if the system is to be regarded as a black box with only input and output signals, system identification can be used to fit a mathematical
Over the last decade, 1.8 billion people worldwide have been affected by disasters triggered by natural hazards and 740 000 lives have been lost. Due to climate change, these numbers are predicted to rise dramatically in the upcoming years. In disaster prone areas, remote communities and lower income countries are disproportionately affected and often lack the resources to prepare. Locating victim
In Sweden, about 150-200 children annually are born with some form of cleft lip and/or palate, making it the most common facial malformation in the country. Treatment often involves one or more surgeries and the speech development is followed up by a speech pathologist from the first year of life. One of the most common speech deviation for children with a cleft palate is hypernasality, which come
A review of existing life cycle assessments on food waste management was made with two main aims. Firstly, to make an overview of the assessments of the global warming potential from the treatment alternatives incineration, landfill, anaerobic digestion and compost in studies reported in literature. Secondly, to identify decisive factors in general and related to system boundary settings in partic
Abstract Perforations are one of Tetra Paks oldest inventions of how to open their carton packages. They have been a part of Tetra Briks product portfolio for over 30 years and quality testing is important. Bad openability, with plastic residues covering the torn hole, is a problem that needs to be addressed. When tearing a package with perforation all people do it differently. By using a mechan
Populärvetenskaplig sammanfattning: Geografiska informationssystem på internet är ett relativt nytt fenomen som främst har utvecklats från ett behov att distribuera geografisk data, dvs utbyte av digitala geografiska data och tillhörande tjänster. Men det är även ett kraftfullt verktyg för att presentera information på internet. Detta examensarbete i naturgeografi syftar till att skapa en webbaGIS on the Internet is a rather new phenomenon, which has evolved from the need of distributed geographical data. It is also a powerful tool for presenting information on the Internet. This master thesis aim to create a web based GIS application with information on lime spreading and the situation concerning acidification in the county of Kronoberg, Sweden. The web based GIS application will be us
Populärvetenskaplig sammanfattning: Småvatten är en svacka eller hålighet som är vattenfylld året om. Dessa småvatten fyller många viktiga funktioner i naturen. De fungerar som utjämnare av flödesvariationer, uppehållsplats och födoplats för många djur och växter och som rena estetiska inslag i naturen, och inte minst som reningsplatser för oönskade näringsämnen så som kväve. Dessa småvatten har iWetlands play an important role in the ecosystem. They reduce the impact of flow flux in the drainage area, acts as upholder of biodiversity, as an esthetic and recreational component in the landscape and they have the ability to reduce nutrients such as nitrogen, and help preventing eutrophication in costal areas. The number of wetlands in Scania have, due to the intensified agriculture been redu
My purpose in this essay is to show how the staff in an institution for young women with a drug addiction, are looking at themselves as "normal" and the young women as "abnormal", and to analyse how sex and gender are made, in interaction with sexuality and class. The essay is based on interviews and a participating observation. The study is made on a compulsory institutional
