In Pursuit of a Stable Stabilization Policy in Sweden. From the Gold Standard to Inflation Targeting and Beyond

In a historical perspective, the stabilization policy regime in Sweden is in a state of constant change, affected by economic crises, international impulses, domestic politics, and developments in macroeconomic theory. Economists have been deeply involved in this process. The current framework for monetary and fiscal policy, with an independent central bank focusing on inflation targeting, and a r

Does innovation add customer value? How servitization affects performance measurement in innovation

This study contributes to a growing stream of literature on servitization in management accounting. In extension to recent explorations in servitization and management accounting, this paper presents how KPIs in innovation reflect the shift towards servitization. The chosen methodology, participatory action design, gives a unique insight how organizations respond and construct KPIs (key performanc

Is Innovation Out of Control?

The aim of this explorative study is to examine the theorical notions in the business model of innovatin that are influence by use of management control systems (MCS). By means of a systematic literature review, the theoretical contrructs are explored and related to part of the MCS, namely the performance measurement systems (PMS) and the business model of innovation (i.e. innovation input, proces

TREatment of ATopic eczema (TREAT) Registry Taskforce : protocol for a European safety study of dupilumab and other systemic therapies in patients with atopic eczema

Background: A long-term prospective observational safety study is essential to characterize fully the safety profile of systemic immunomodulating therapies for patients with atopic eczema. The TREatment of ATopic eczema (TREAT) Registry Taskforce offers a large platform to conduct such research using national registries that collect the same data using a predefined core dataset. Objectives: To pre

Osmotic Concentration of Zebrafish (Danio rerio) Body Fluids is Lower in Larvae than in Adults

We intended to perform optical and structural measurements on larval zebrafish eyes at 5 days post fertilization, that is, the earliest age at which zebrafish show visually guided behavior. However, excised larval crystalline lenses deteriorated quickly if immersed in a medium that gives good results with adult lenses from a variety of fish species. We suspected that the larvae have body fluids of

An advanced internal combustion engine concept for low emissions and high efficiency from idle to max load using gasoline partially premixed combustion

A Scania 13 1 engine modified for single cylinder operations was run using nine fuels in the boiling point range of gasoline, but very different octane number, together with PRF20 and MK1-diesel. The eleven fuels were tested in a load sweep between 5 and 26 bar gross IMEP at 1250 rpm and also at idle (2.5 bar IMEP, 600 rpm). The boost level was proportional to the load while the inlet temperature

Influence of inlet pressure, EGR, combustion phasing, speed and pilot ratio on high load gasoline partially premixed combustion

The current research focuses in understanding how inlet pressure, EGR, combustion phasing, engine speed and pilot main ratio are affecting the main parameters of the combustion (e.g. efficiency, NOx, soot, maximum pressure rise rate) in the novel concept of injecting high octane number fuels in partially premixed combustion. The influence of the above mentioned parameters was studied by performing

How hythane with 25% Hydrogen can affect the Combustion in a 6-Cylinder Natural-Gas Engine

Using alternative fuels like Natural Gas (NG) has shown good potentials on heavy duty engines. Heavy duty NG engines can be operated either lean or stoichiometric diluted with EGR. Extending Dilution limit has been identified as a beneficial strategy for increasing efficiency and decreasing emissions. However dilution limit is limited in these types of engines because of the lower burnings rate of

Effects of ethanol and different type of gasoline fuels on partially premixed combustion from low to high load

The behavior of Ethanol and seven fuels in the boiling point range of gasoline but with an Octane Number spanning from 69 to 99 was investigated in Partially Premixed Combustion. A load sweep was performed from 5 to 18 bar gross IMEP at 1300 rpm. The engine used in the experiments was a single cylinder Scania D12. To allow high load operations and achieve sufficient mixing, the compression ratio w

Model based TDC offset estimation from motored cylinder pressure data

Finding the correct top dead center (TDC) offset for an internal combustion engine is harder than it seems. This paper introduces a novel method to find the TDC offset based on a simple assumption that the heat loss power through the combustion chamber walls is constant for motored cycles in a narrow crank angle interval around TDC. The proposed method uses nonlinear least squares optimization to

Thermodynamic modeling and control of a negative valve overlap turbo HCCI engine

It is tractable to increase the torque for an HCCI engine and one way is to add a turbocharger. Operating in HCCI mode requires accurate control of the combustion phasing, CA50. The higher the engine torque, the narrower the CA50 window becomes where HCCI operation is maintained. As the CA50 varies stochastically between cycles this requires improved CA50 control for turbo HCCI engines. The main f
