Case study is a suitable research methodology for software engineering research since it studies contemporary phenomena in its natural context. However, the understanding of what constitutes a case study varies, and hence the quality of the resulting studies. This paper aims at providing an introduction to case study methodology and guidelines for researchers conducting case studies and readers st
To provide for a high QoS in a cellular network, each call should be assigned to its preferred cell and priority given to already ongoing calls. Herein, a combined speed-sensitive layer selection method and dynamic guard channel scheme, called CLARR, for use in hierarchical networks, is introduced. To reduce the complexity, partially the same speed estimation and measurement procedures are applied
Structure-property relationships of polymers incorporating Lewis acidic boron in their branched chain architecture were investigated as a function of LiClO4 salt concentration. The polymers were synthesised from boron trioxide, and different poly(ethylene glycol)s (PEGs) and monomethyl ether end-capped PEGs. The PEG-boronate ester polymers based on PEGs having molecular weights equal to, or below,
The objective of the seminar was to summarize, discuss, question and conclude the present state-of-the-art on prediction models for corrosion initiation due to chloride ingress in structures exposed to sea water and de-icing salts. Papers were presented on various topics. A test case was designed and the experts made predictions of chloride ingress for this well-defined case.
The paper argues that the final value of an object, i.e., its value for its own sake, need not be intrinsic. It need not supervene on the object’s internal properties. Extrinsic final value, which accrues to things (or persons) in virtue of their relational features, cannot be traced back to the intrinsic value of states that involve these things together with their relations. On the opposite, suc
Popular Abstract in Swedish Denna avhandling består av en tillämpad och en teoretisk del. I den tillämpade delen studeras tänkbara riskfaktorer för blodsjukdomarna myeloisk leukemi (ML) och myelodysplastiska syndrom (MDS). Den teoretiska delen tar upp några metodproblem som kan uppstå i epidemiologiska undersökningar som utnyttjar databaser innehållande uppgifter om andelen personer i olika yrkesgCase-control studies comprising telephone interviews for 333 cases of acute myeloid leukemia (AML), 226 cases of Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML), 330 cases of myelodysplastic syndromes (MDS), and matched controls were conducted. Information had to be obtained from next-of-kin much more often for cases (85%) than for controls (18%). Tobacco smoking was associated
A general approach to derive summation rules in electromagnetics using Herglotz functions is presented in this paper. This approach is then used to obtain summation rules and bounds on partial wave scattering, which are illustrated numerically by the scattering of a Drude sphere.
Cellulose can be chemically modified to produce derivatives with specific properties. Knowledge of correlations between the modification reaction, substituent distribution, origin of cellulose and properties are importaint in order to design processess so as to produce derivatives with the desired properties. This thesis describes research on newly developed analytical methods for the analysis of

Phase diagrams are useful tools to study the phase equilibria of nanowire materials systems because the growth of nanowires is accompanied by phase formation and phase transition. We have modeled the phase equilibria of the As-Au-Ga ternary system by means of the CALPHAD method. This method is a well-established semi-empirical technique for thermodynamic modeling in which Gibbs energy functions wi
People who suffer from swallowing disorders, commonly referred to as dysphagia, are often restricted to a texture-modified diet. In such a diet, the texture of the fluid is modified mainly by the addition of gum or starch-based thickeners. For optimal modification of the texture, tunable rheological parameters are shear viscosity, yield stress, and elasticity. In this work, the flow properties of
This article focuses on media engagement within the reality television industry. Itdraws on qualitative research of production practices and audience participationin live reality events to explore the multiple meanings of engagement as a series ofrelationships between creative and executive producers, broadcasters, performers,and audiences. A key question concerns how do producers and audiencescoc
