Robust distributed routing in dynamical networks -- Part II: strong resilience, equilibrium selection and cascaded failures

Abstract in UndeterminedStrong resilience properties of dynamical networks are analyzed for distributed routing policies. The latter are characterized by the property that the way the outflow at a non-destination node gets split among its outgoing links is allowed to depend only on local information about the current particle densities on the outgoing links. The strong resilience of the network is

Feasible provision of targeted traveler information in public transportation: Segmentation based on functional limitations

This paper presents findings on the need for traveler information among people with functional limitation(s), and how the need varies between groups with different functional limitation(s). Chi-Squared Automatic Identification Detector (CHAID) was used to identify groups (segments) in order to understand how functional limitations contribute to the need for traveler information. The key findings s

Adsorption versus aggregation. Particles and surface of the same material

A model for the adsorption of colloidal particles on a planar surface is analyzed by using a thermodynamic chemical equilibrium model and Monte Carlo simulations. Central to this investigation are that (i) particles and surface are considered to be of the same material and (ii) the particle-surface and particle-particle interactions are related using the Derjaguin approximation using a surface-sur

A study of glycoprotein-lectin interactions using quartz crystal microbalance.

A study of biospecific interactions between lectins and glycoproteins using a quartz crystal microbalance biosensor with dissipation monitoring (QCM-D) was reported. Four lectins were covalently immobilised on the thiol-modified gold electrode of the QCM chips in order to obtain sensing surfaces. The frequency shift served as analytical signal and the dissipation shift provided additional informat

Analogy at war: proportionality, equality and the law of targeting

This text is an inquiry into how the international community is understood in and through international law. My prism for this inquiry shall be the principle of proportionality in international humanitarian law, relating expected civilian losses to anticipated military advantage. To properly understand proportionality, I have to revert to the structure of analogical thinking in the thomistic tradi

Mellan kungar och kaniker : Dalby till debatt

A discussion on the relationship between the church and the manor, the socalled westwork and the socalled royal palace at Dalby. The palace is interpreted as a monastery and the westwork as a "Galilaea", both from the 12th C.

Analytical sociology is a research strategy

Analytical sociology is a methodological strategy aimed at refining theoretically informed empirical social research. Given the central assumption that the role of sociology is to explain macro level phenomena, analytical sociology makes pragmatic use of abstract models of social action and interaction, such as the DBO-model. The realization that it is not a philosophy or a psychology, nor a unive

Live or Let Die? Alternative Routes to Industry Exit

Each year around 8% of Swedish manufacturing firms leave an industry. Of the exit routes available, the least likely is firm closure. Firms are more likely to merge, become acquired or switch to a new industry. We investigate the importance of a range of firm and industry characteristics for the exit decision of Swedish firms from 1980–1996. From our analysis two patterns are evident. First, firms

Added diagnostic utility of CT perfusion and CT angiography in acute ischemic stroke. Evaluation of three different patient categories

Patients with a clinical picture of acute ischemic stroke are a heterogeneous group. The aim of this study was to evaluate the added utility of CT perfusion (CTP) and CT angiography (CTA) in the workup of three different categories of acute ischemic stroke patients. Fifty patients (61 +/- 05 years old) were included in this retrospective analysis. Twenty-nine patients had transient ischemic attack

A sequential method to identify underlying causes from industrial accidents reported to the MARS database

This paper presents a method designed to identify underlying causes leading to industrial accidents. The method developed intends to facilitate the learning process from accidents by identifying possible causes related to the accidents that were not directly stated in an accident report, but that can be deduced following the description of the event, in particular with regard to the quality of the

Sustainable development in general and urban context: A literature review

This report is a literature review about sustainability and sustainable development in general and in an urban context. It focuses on theoretical issues and debates in scientific literature and aims at analyzing the different dimension of sustainability, namely social, ecological and economic sustainability. There are different conflicts between those dimensions of sustainability. Furthermore, the

Genreteoretiska fundamenta

Todorov´s distinction between theoretical genres and historical genres are logically analyzed, the first being classes, the second cultural, social facts. The theoretical genres cannot, according to Todorov, be falsified or verified. This is on account of the rule saying that the language of object and the metalanguage must not be mixed. But this mixing is always present in ordinary language, in l

Self-efficacy and strategies to influence the study environment.

This study investigates the relationship between student influence and academic self-efficacy in a sample of 275 students in two Master’s programmes in Engineering. Students in only one of the programmes studied according to problem-based learning (PBL). Results indicate that students choosing strategies to influence course content or structure, through course evaluation and recommending changes t

Homogeneous large-area graphene layer growth on 6h-SiC(001)

Homogeneous large-area graphene monolayers were successfully prepared ex situ on 6H-SiC(0001). The samples have been studied systematically and the results are compared with those from a sample cut from the same wafer and prepared by in situ heating. The formation of smaller graphene flakes was found on the in situ prepared sample, which is in line with earlier observations. Distinctly different r
