Discrete Time Markov Chains (DTMCs) and Con- tinuous Time Markov Chains (CTMCs) are often used to model various types of phenomena, such as, for example, the behavior of software products. In that case, Markov chains are widely used to describe possible time-varying behavior of “self-adaptive” software systems, where the transition from one state to another represents alternative choices at the so
Radio links in wireless mesh networks (WMN) can select one of several modulation and coding schemes (MCS). A MCS assignment influences links data rates and their mutual interference, and therefore should be optimized. We consider joint optimization of link rate assignment and transmission scheduling in order to maximize the minimal flow in a WMN. One of the main difficulties stems from the require
Popular Abstract in Swedish Byggnadsprestanda – Metoder för förbättrad prediktering och verifiering av energianvändning och inneklimat Hans Bagge, Byggnadsfysik LTH Introduktion För att kunna minska utsläpp av växthusgaser och rädda klimatet på jorden är det av yttersta vikt att vi kan bygga byggnader med låg energianvändning och bra inneklimat. Byggnader står i dagsläget för mellan 30 och 40 %Reducing CO2 emissions is one of the most important goals in Europe as well as the rest of the world. To reach that goal, the use of energy must be reduced. Thus, the building industry is facing a great challenge. Not only energy efficiency but also sustainability is desirable in the building stock. This thesis presents and suggests methods that can be used to improve prediction and verification o
Laser Shock Peening (LSP) and Shot Peening (SP) are processes used to mechanically alter the surface properties of metals by inducing a transient high-pressure wave by a laser pulse or by a high-velocity impact of a peening particle. Both processes aim to induce compressive residual stresses near the surface and the level of residual stresses obtained from SP or LSP is similar. When austenitic steLaser Shock Peening (LSP) and Shot Peening (SP) are processes used to mechanically alter the surface properties of metals by inducing a transient high-pressure wave by a laser pulse or by a high-velocity impact of a peening particle.

We propose a method for estimating the 3D position of a target point, given multiple measurements of it, using mm-wave radar data. Given azimuth headings and range estimates from posed radar positions, we find the 3D position, using an approximate, but geometrically and statistically meaningful cost. The 3D position is found in an optimal way, using this approximate cost. By deriving the Lagrangia
Even though urban cemeteries in Sweden today can be seen as making space for different memorial practices, they are also a materialization of certain cultural and religious norms (Kjaersgaard & Venbrux, 2016), which sometimes are expressed as functional and aesthetic values. In this respect, the urban cemetery has an abiding attitude to change in building on past traditions and designs to addrEven though urban cemeteries in Sweden today can be seen as making space for different memorial practices, they are also a materialization of certain cultural and religious norms (Kjaersgaard & Venbrux, 2016), which sometimes are expressed as functional and aesthetic values.

Aim: Allometric relationships, which describe plant growth patterns shaped by environmental conditions, reflect functional trade-offs and represent key functional traits that optimise adaptation, resource acquisition, stress tolerance and competition. Here, we assess how these allometric relationships and associated functional trade-offs drive ecosystem structure, functioning and competitive inter
Business opportunities are a chance for a company to grow its activity and to further the aggregate welfare of the society as a whole. Corporate opportunities rules and their functional equivalents should enable companies to develop their business activities when directors discover those business opportunities.

Soils play a critical role in the carbon (C) cycle by regulating the atmospheric carbon dioxide (CO2) levels, and correspondingly the Earth’s climate. However, there are still countless questions of how biological and geochemical soil processes affect the C cycle. To be able to predict future implications on the Earth’s climate, we need to understand these processes. Globally, soils store more C tIron oxide nanoparticles are involved in several important biogeochemical processes. The interfaces between aqueous solutions and iron oxide nanoparticle surfaces are found everywhere in nature, and the chemical and microbial processes occurring at these complex interfaces control e.g. nutrient and contaminant availability and transport. Recently, it has been shown that certain ectomycorrhizal (EC
People building their own houses have, at least theoretically, substantial autonomy when choosing, for example, a heating system and windows. In this article, focus is on the process of building new single-family houses and how energy efficiency and energy-efficient technology are incorporated into the building process. The conclusions emphasize energy as only one factor in housing purchase decisi
Oilseed rape fields are a very common crop in the agricultural landscape of southern Sweden, and they can harbour surprisingly many insect species. Some of them are herbivores that feed on various parts of the oilseed rape plant, others are natural enemies of the herbivores, and even more species are tourists from the surrounding landscape. In my thesis I have studied these insects and how their pOilseed rape fields are a very common crop in the agricultural landscape of southern Sweden, and they can harbour surprisingly many insect species.

Considerable effort has been dedicated over the years to model and simulate the ultrafiltration process. Most approaches are theoretical and therefore not applicable to industrial process streams. When treating such solutions, a combination of experiments and simulations is needed. In this thesis, a method has been developed for design and optimization of UF plants. The method uses experiments in
Despite slow ongoing progress in increasing the representation of women in academia, women remain significantly under-represented at senior levels, in particular in the natural sciences and engineering. Not infrequently, this is downplayed by bringing forth arguments such as inherent biological differences between genders, that current policies are adequate to address the issue, or by deflecting t
The stable sedimentary nitrogen isotope compositions of bulk organic matter (δ15Nbulk) and the silicon isotope composition of diatoms (δ30SiBSi) both mainly reflect the degree of past nutrient utilization by primary producers. However, in ocean areas where anoxic and suboxic conditions prevail, the δ15Nbulk signal ultimately recorded within the sediments is also influenced by water column denitrif

Growing interest is awarded to the digitalization of the building permitting use case and many works are developed about the topic. However, the subject is very complex and many aspects are usually tackled separately, making it very hard for traditional literature reviews to grasp the actual progress in the overall topic.
