This work concerned experimental studies of heat transfer in a light-duty diesel engine. Combustion is affected by several parameters, such as pressure, engine speed, mass of injected fuel and in-cylinder gas flow. These parameters are in turn affected by the combustion chamber geometry and fuel spray characteristics. At high load the exhaust heat was increased more than at high engine speed. Swir

The purpose of dynamic asset allocation (DAA) is to overcome the challenge that changing market conditions present to traditional strategic asset allocation by adjusting portfolio weights to take advantage of favorable conditions and reduce potential drawdowns. This article proposes a new approach to DAA that is based on detection of change points without fitting a model with a fixed number of reg

Popular Abstract in Swedish Ny kunskap gör det möjligt att med hjälp av DNA-information välja ut vilka kvigor/kor som förväntas ge en hög mjölkavkastning, höga halter av mjölkens komponenter och optimala egenskaper för ostproduktion. Denna information kan användas för att bättre anpassa mjölkens sammansättning och processegenskaper med de svenska mejeriernas behov för att på så vis förbättra mjölkMilk genomics is a new area of research that explores the relations between cow genetics and milk characteristics. Identifying the genes controlling compositional and technological traits of milk will give opportunities to select cows for targeted milk production. In this thesis, the impact of different genetic approaches, i.e. quantitative genetic evaluation, single gene effects and genomic selec

The empirical part of this study is based on a survey of 600 Swedish households and a number of interviews where questions about residential energy behaviour and possible policy instruments for change were raised. The study provides insight into current behavioural patterns and gives a bottom-up perspective on the realistic perspective potentials for change and ways to achieve them. Residential en

In this paper we discuss social policy in relation to different development contexts, where characteristics and outcomes of social policies in different sectors ( e.g.,housing, care, education, social security) are compared. The paper relates to the discussion on the causes and outcomes of welfare state management in different contexts. However, existing analytical models do not fit the mixtures o

It was a great pleasure for us to discover that the March issue of the CM Journal was dedicated to SCM metrics. We have been interested in SCM metrics for a long time and have worked with them for the past couple of years. So it was with great interest and curiosity that we read through the five papers in the issue. However, the more we read, the more we realised that there are two - to us - very

Oppositional pre-electoral coalition formation has, in a number of recent studies, been proven to have an important effect on the prospects for liberalizing electoral outcomes in authoritarian elections. Despite this recent recognition of oppositional coalitions as a trigger for democratization, almost nothing is known about when these coalitions are formed. An important explanation for the la

It is well known that Max-Weight type scheduling algorithms are throughput optimal since they achieve the maximum throughput while maintaining the network stability. However, the majority of existing works employing Max-Weight algorithm require the complete channel state information (CSI) at the scheduler without taking into account the associated overhead. In this work, we design a Scheduling and
