Assessment of robustness of structural systems very often involves assessment of the structural response after local damage. In this paper an attempt is made to describe the state of art in this field with focus on methods which can be used in engineering practice. Advanced non-linear and dynamic computer tools are available today which can deal with most of the above mentioned phenomena but they
Background: Patients presenting with synchronous colorectal liver metastases are increasinglybeing considered for a curative treatment, and the liver-first approach is gaining popularity in thiscontext. However, little is known about the completion rates of the liver-first approach and itseffects on survival.Methods:A systematic review and meta-analysis of liver-first strategy for colorectal liver
Background. Seeking to clarify the parent-offspring transmission of Major Depression (MD) and type I Bipolar Disorder (BD), we examined offspring MD and BD risk in five informative parental pairs: Unaffected x MD, Unaffected x BD, MDxMD, MDxBD and BDxBD. Methods. We identified 289,637 individuals born in Sweden 1970-1990, followed through 2018, from parents with MD and/or BD identified from Swedis
Proton exchange membrane fuel cells (PEMFCs) are expected to play a significant role in the next generation of energy systems and road vehicles for transportation. To achieve high performance, low cost and high reliability, significant attention is needed on detailed modeling and simulation of various physical processes in PEMFC unit-cells. Substantial effort is also required to reach proper water
We investigate the use of particle filter (PF) estimation techniques on a hovercraft vehicle in an office environment. Monte Carlo Localization (MCL) with particle filtering is a popular method for localizing robots with laser range finders. In maps featuring long, uniform corridors though, a PF can produce low confidence estimates. When used as feedback to control an unstable vehicle this can pro
III-V MOSFETs are currently being considered for digital applications, whereas the option to develop the technology for RF-applications is less often discussed. The quality of the semiconductor/high-k interface and the presence of border traps within the high-k film plays an important role in both types of transistors, but given the different sets of transistor metrics, their influence is differen

This thesis studies the computational complexity and polynomial-time approximability of a number of discrete combinatorial optimization problems involving labeled trees and strings. The problems considered have applications to computational molecular biology, pattern matching, and many other areas of computer science. The thesis is divided into three parts. In the first part, we study some proble
Popular Abstract in Swedish Denna avhandling syftar till att föreslå, utvärdera och applicera testprocedurer för rationalitet, svag separabilitet och effektivitet. Främst behandlas icke-parametriska så kallade ’revealed preference’ procedurer, vilka har fördelen att de, till skillnad från den parametriska ansatsen, inte behöver anslå någon funktionell form för nyttofunktionen. En majoritet av de tThis thesis aims to propose, evaluate and apply test procedures for rationality, weak separability and efficiency. In particular, it focuses on nonparametric revealed preference procedures. This approach has the advantage of not having to stipulate any functional form for the utility function, unlike the parametric approach which relies on finding a suitable functional form for the utility functio
The theory of ecologically unequal exchange (EUE) posits that international trade is structurally organized in a manner that allows a net transfer of resources from peripheral developing to core industrialized countries. The consequence, it is argued, is under-development in the periphery and augmented productive capacity in the core. EUE thus challenges the neoliberal free-market argument that ex
Popular Abstract in Swedish Inom processanalytisk kemi är uppgiften att bestämma viktiga egenskaper i en kemisk process under det att tillverkningen fortlöper. Ett vanligt exempel är att man bestämmer halten av något ämne. Eftersom de uppmätta egenskaperna ofta används för att styra processandet mot bästa möjliga betingelser är det av generellt intresse att mätningen går snabbt. Men det är inte noPharmaceutical tablets and pellets are often covered with a coating. There is a need for methods that enable monitoring of the growth of such films during processing. Such analyses can be performed using process analytical chemical methods based on near infrared (NIR) diffuse reflectance spectrometry. It provides with analyses that take only ca. 8 seconds in total analysis time, including physical
In a uniform granite gneiss study area in central Zimbabwe, lineaments oriented parallel to the maximum regional compressive stress orientation exhibit the thickest regolith development, while lineaments oriented perpendicular to the maximum compressive stress show the shallowest development of weathered regolith. The principal fracture set orientations were mapped using aerial imagery. The region
