This study focuses on modelling the cutting resistance as a function of the workpiece material properties. Thus, for a workpiece material the cutting resistance may be predicted from the material properties without using any experiments. The cutting resistance may then be used to determine the cutting forces, data which in turn may be used to determine appropriate process parameters and select cut

Background: When firms grow through acquisitions it is commonly debated whether the two entities ought to be better off as standalone companies rather than as a merged company. This thesis aims at discussing this issue of M&As advantages and disadvantages in terms of source of synergies from the perspective of resource allocation. Purpose: The purpose of this thesis is to describe and analyze

The aim of this paper is to empirically investigate if there is a correlation between the duration of trade and economic integration. Theoretically, this is done by analyzing how economic integration affects sunk costs of exporting. Using the Kaplan-Meier methodology we calculate survival probabilities for German and Russian imports. Import data is derived at the 2-digit product level from 1993-20

Järnvägen utgör grunden för pendeltrafiken inom region Stockholm och störningar i järnvägstrafiken påverkar många resenärer. En vanlig orsak till störningar i järnvägstrafiken är att obehöriga personer vistas vid spåren. Mellan 2010-01-01 och 2015-05-18 har närmare 1100 händelser med obehöriga vid spår rapporterats i region Stockholm, varav drygt 80 fall resulterat i personpåkörningar med dödligt

The purpose of this study is to quantitatively verify the relationship between corporate default probability and macroeconomic information. The purpose is further to compare the results of the panel data analysis for the firms from the Large Cap Index with the empirical findings generated by a similar model for the firms from the Mid & Small Cap Indexes. Also, the study aims to examine to whic

This paper contains decision analytical approaches, conditions and models for the quantification of decision values for built environment systems. Specifically, (1) delta formulations of objective functions for decision value quantification are introduced, (2) conditions for decision value are identified and (3) action value analysis formulations are further developed. The delta objective function

The social-aid institution has been analyzed almost exclusively from a social problems approach, aiming at the understanding of social aid clients as a social problem. This article views them from a different angle, as a sociological category occupying a unique position in society. Following Simmel, we deal here with those who are poor in a social sense, i.e., anyone receiving public assistance. I

One of the key implications of COVID-19 is the adoption of physical distancing provisions to minimise the risk of virus transmission. Physical distancing can have significant consequences on crowd movement both in normal conditions and during emergencies. The impact of physical distancing is discussed in this chapter by first presenting an overview of its implications on crowd dynamics and space u

The magnetic Laplacian on a planar domain under a strong constant magnetic field has eigenvalues close to the Landau levels. We study the case when the domain is a disc and the spectrum consists of branches of eigenvalues of one dimensional operators. Under Neumann boundary condition and strong magnetic field, we derive asymptotics of the eigenvalues with accurate estimates of exponentially small

The ordinance installed the first legally sanctioned freedom of the press in the world and was preceded by decades of discussions, proposals, and investigations. The issued ordinance was a compromise between various interests; it was not the unlimited freedom of the press that many had hoped for. Prior censorship was abolished except for theological writings, but it was still forbidden to publish

There is always an interesting side for any lawyer or law student concerning the study of the ship arrest. The continuous development for this type of action in the maritime law gives it a significant importance. This action implemented against the ship to secure a claim that is of a maritime nature, in other words directed against the ship and not the ship owner. Since the adoption of the 1952 Ar

The thesis evaluates the Swedish EITC and its effect on the employment rate. The Swedish EITC was introduced in 2007 to encourage more people to enter the labor market. This will be evaluated with a difference-in-difference method. The fact that the tax rate in the municipality is an important part of the formula for the EITC will be used to form groups depending of the size of the tax rate. A mun

The relation between the so called basis set superposition error and intramolecular vibrational frequencies calculated at the Hartree Fock SCF level of approximation was investigated. A linear conformation of HF dimer was chosen as test system for the investigation. It was found that the direct basis set superposition error for the studied system is rather small. It was further found that the shif
