Bioadsorbents of heavy metals from coal mines area in Mozambique

Mozambique is one of the largest coal exporters in Africa. Usually miningactivities generate polluted water that is discharged into the Zambezi river basin in the Moatize area without treatment, increasing the risk both to the local environment and to public health because of this water containing significant amounts of metals and metalloids. At the same time, Mozambique is one of the largest prod

User involvement in housing recovery : Cases from Haiyan affected areas in the Philippines

The aim of this study is to develop a better understanding of the relation between housing recovery and user involvement from a capability perspective. The thesis studies housing recovery in areas affected by typhoon Haiyan, which struck the Philippines on 8th November 2013. The focus is on three perspectives: a) approaches to housing reconstruction, b) explanation for unexpected housing outcomes,

Charge transport in III-V narrow bandgap semiconductor nanowires

This thesis describes charge transport in III-V narrow bandgap semiconductor nanowires. We are particularly interested in quantum transport in InSb, InAs and InP-InAs core-shell nanowires. According to the type of transport mechanism dominating in the devices, this thesis can be divided into four parts.In the first part of this thesis, we investigated the temperature dependent transport properties

Bortglömda utgrävningar grävs fram : Bronsåldersgravarna i Pangs hög och Hässlehögen

Re-excavations of forgotten archaeological material are more relevant than ever. What is not ordered published or digitized risks to become invisible in storages and archaeological research. With new investigations of archaeological contexts and osteological material the article updates our knowledge of Late Bronze Age burials in North-Western Skåne, Sweden.

Dynamic Mapping of Diesel Engine through System Identification

From a control design point of view, modern diesel engines are dynamic, nonlinear, MIMO systems. This paper presents a method to find low-complexity black-box dynamic models suitable for model predictive control (MPC) of NOx and soot emissions based on on-line emissions measurements. A four-input-five-output representation of the engine is considered, with fuel injection timing, fuel injection dur

Object Tracking with Measurements from Single or Multiple Cameras

To be able to determine the position of a static object in 3D space by means of computer vision, it has to be seen by cameras from at least two different view points. The same applies for measuring the position of a moving object based on images captured at one single time instant. However, if the cameras are not synchronized in time, or if a moving object is not visible in all images, one can not

Experimental Evaluation of Predictive Combustion Phasing Control in an HCCI Engine using Fast Thermal Management and VVA

This paper presents experimental results on model predictive control of the combustion phasing in a Homogeneous Charge Compression Ignition (HCCI) engine. The controllers were based on linearizations of a previously presented physical model of HCCI including cylinder wall temperature dynamics. The control signals were the inlet air temperature and the inlet valve closing. A system for fast thermal

Sewage sludge-based activated carbon – Production and potential in wastewater and stormwater treatment

SummarySustainable sewage sludge management has been a heavily debated topic in Europe for more than a decade. Due to its content of pollutants such as heavy metals, pharmaceuticals and other organic micropollutants, the use of sewage sludge for farmland application is currently banned or restricted in most European countries. Therefore, alternative methods for sludge management are discussed. The
