Pressure oscillations during rapid HCCI combustion

This work has focused on studying the in-cylinder pressure fluctuations caused by rapid HCCI combustion and determine what they consist of. Inhomogeneous autoignition sets up pressure waves traversing the combustion chamber. These pressure waves induce high gas velocities which causes increased heat transfer to the walls or in worst case engine damage. In order to study the pressure fluctuations a

Epistemic Attitudes and Source Critique in Qualitative Research

In this essay, we explore and discuss current practices of source critique. In our empirical analysis of a sample of interview-based studies, we find that few studies show a careful and reflective stance toward their sources. In the majority of cases, we discern a tendency to either ignore basic issues of the trustworthiness of interview material or produce technical descriptions which seem to hav

Intergenerational Transmission of Human Capital : Is it a One-Way Street?

Studies on the intergenerational transmission of human capital usually assume a one-way spillover from parents to children. However, children may also affect their parents’ human capital. Using exogenous variation in education, arising from a Swedish compulsory schooling reform in the 1950s and 1960s, we address this question by studying the causal effect of children's schooling on their parents’

In-cylinder measurement for engine cold-start control

We examine the use of in-cylinder measurements for engine control, with emphasis on emissions control during cold start. First, the cold start emissions control problem is described. An overview of previous research in the area of in-cylinder measurements for control is presented, including sensors for pressure and other quantities. Next, analysis of cylinder pressure is described. Lastly, a cold-

Hybrid control of a manufacturing transport system

This paper describes the design of a least restrictive, safe hybrid control scheme for a manufacturing transport system transporting fragile objects from a production unit to a stamping/packaging station. The control scheme consists of several control modes. One control mode handles trajectory following using time-optimal control, the other control modes are safety related and are engaged in a lea

International Import Competition and the Decision to Migrate : Evidence from Mexico

We analyze the effects of the increase in China’s import competition on Mexican domestic and international migration. We exploit the variation in exposure to competition from China, following its accession to the WTO in 2001, across Mexican municipalities and estimate the effect of international competition on the individual decision to migrate. Controlling for individual and municipality features

Polynomial Reconstruction of 3D sampled Curves Using Auxiliary Surface Data

This paper proposes a method for structural enhancement of a 3D sampled curve. The curve is assumed to be organized, but corrupted with low frequency noise. The proposed method approaches the notion of curve reconstruction in a novel way, where information about the structure in a scanned surface is used to reconstruct the curve. Principal Component Analysis is carried out on successive neighborho

‘A forest of urbanization’: Camp Metropolis in the edge areas

This article examines two issues located at the core of thePalestinian struggle: Jerusalem and the refugee camps. I aim totrace the forced encounter staged at these two crucial sites ofcontestation, while looking at the collisions/interactions that occurbetween them, and the types of geographies that are producedwithin an experience of abandonment. This is done by exploringhow the colonized re-pro

Shifting realities: dislocating Palestinian Jerusalemites from the capital to the edge

Lefebvre’s ‘right to the city’ was an expression of a new politics of citizenship,residency and above all the right to urban life. We thus build our argument inthis paper on the Lefebvre concept and through the case study of Kufr Aqab, thenorthernmost neighbourhood of the occupied city of Jerusalem. In order tosystematically displace Palestinian Jerusalemites and to achieve the Judaisationof Jerus

State Making and Swedish Politics in the North

Recently the 19th century as a formative period of both states and the state system has received more attention by IR scholars, historical sociologists, and historians. A highly generalized argument that this diverse literature has in common is that the state became more state-like, and the international system denser, and therefore more system-like, in the 19th century. The modern world has its r

Strategies for bringing stem cell-derived dopamine neurons to the clinic : A European approach (STEM-PD)

The treatment of Parkinson's disease (PD) has for over 50 years relied on dopaminergic therapies that are highly effective especially in the early years of the condition, but ultimately are limited by the development of side effects that relate to the nonphysiological stimulation of dopamine receptors including in nonstriatal areas. Targeted regenerative therapies designed to restore specifically

Is Obesity More Than a Double Burden among People with Mobility Disability? : The Effect of Obesity on HRQoL and Participation in Society

Obesity is more common in individuals with mobility disability than in those without this condition. Individuals with mobility disability also have lower health-related quality of life (HRQoL) and are limited in their participation in society. Therefore, this study aimed to investigate the body mass index (BMI) status and the association of overweight or obesity on HRQoL and participation in socie

This paper analyses the hegemony of the growth paradigm through the example of its naturalisation in capitalist production and consumption relations. Applying a combination of theoretical elements from the Marxian tradition, the Regulation approach and Bourdieusian sociology, emphasis is placed on how the growth imperative is reflected in people’s minds and bodies. It becomes hegemonic because it

Fem år av tillgänglighet, närhet och synlighet : LUB:s forskarstöd 2012-2017

För fem år sedan publicerades ”Tillgänglighet, närhet och synlighet”, en slutrapport för ett projekt som syftade till att inventera forskares behov av forskarstöd vid LU. I år, 2017, valde arbetsgruppen för Forskning och Forskningsprocesser inom LUB, att göra om en av delarna i projektet nämligen den enkätundersökningen som gick ut till de olika delarna av biblioteksorganisationen och som låg till
