Background: Sandvik is in the middle of a great investment, the so called Green Field investment, which will imply a new factory for parts of their stone crush production. The facility is, at current situation, in engineering phase and the preparations are in focus and running at high speed. Purpose: The aim of this master thesis and final course in the education is to give an insight and valuable

As the largest single energy-consuming component in most biological wastewater treatment systems, control of aeration is of great interest seen from an energy savings point of view. This paper suggests a simple way of using on-line ammonium measurements to control aeration in a pre-denitrification plant by controlling the dissolved oxygen setpoint. The controller works primarily by feed-forward ba

In this paper a combustion diagnostic method is presented where measured pressure data is used to calculate the heat release, local temperatures and concentrations of NO and other species. This is done by a multizone model where the lambda value, i.e. 1/equivalence ratio, in each zone can be chosen arbitrarily. In homogenous charge engines lambda is given by the global air/fuel ratio. The local la

Vid årsskiftet 2009/2010 så trädde konfliktlösningsregeln i kraft i svensk lagstiftning. Konfliktlösningsregeln är ett tillägg i KL:s 3 kap och tar sikte på att lösa de konkurrensproblem som kan uppkomma vid offentlig säljverksamhet. Enligt den så kan stat, kommun eller landsting förbjudas att bedriva ett visst förfarande i sin säljverksamhet ifall detta snedvrider eller hämmar konkurrensen eller On the 1st of January 2010, new rules were enforced in the Swedish Competition Act (KL). The new legislation has the character of a conflict resolution rule and is based in the 3rd chapter of KL. The aim behind the rule is to solve the competition conflicts that can arise when public operators compete with private operators in open markets. The government, municipality or a county can be prohibite

Idag lever vi en globaliserad värld där varor, tjänster och personer rör sig över större avstånd på ett allt enklare och snabbare sätt. Detta har resulterat i att fler företag har valt att etablerat sig internationellt och i allt större utsträckning strävar efter att etablera sig och verka globalt. När företag verkar i flera länder är en av konsekvenserna att företagen måste efterfölja lagar och rToday we live in a globalized world where goods, services and people can move easily over wide distances smoother and faster for each day. This has resulted in an increasing number of companies striving to establish and operate globally. One of the consequences when companies establishes worldwide is that they must comply with laws and regulations in the countries where they choose to establish. T

Germinal matrix-intraventricular hemorrhage (IVH) occurs in nearly half of infants born at less than 26 weeks' gestation. Up to 50% of survivors with IVH develop cerebral palsy, cognitive deficits, behavioral disorders, posthemorrhagic ventricular dilatation, or a combination of these sequelae. After the initial bleeding and the primary brain injury, inflammation and secondary brain injury might l

Droplets generated by talking and coughing play a major role in the spreading of COVID-19. Thus, there is a need for accurate measurements of the physical properties of exhaled droplets just at the exit of the mouth, including their number and velocity. Several challenges are associated with imaging coughed droplets. First, large variation of droplet size will translate to a large range of signal
