Study on Combustion Chamber Geometry Effects in an HCCI Engine using High-Speed Cycle-Resolved Chemiluminescence Imaging
The aim of this study is to see how geometry generated turbulence affects the Rate of Heat Release (ROHR) in an HCCI engine. HCCI combustion is limited in load due to high peak pressures and too fast combustion. If the speed of combustion can be decreased the load range can be extended. Therefore two different combustion chamber geometries were investigated, one with a disc shape and one with a sq

WHAT ARE THE CHARACTERISTICS OF AIRBORNE PARTICLES THAT WE ARE EXPOSED TO? Focus on Indoor Environments and Emissions from Biomass Fired District Heating
Ambient fine particulate matter PM2.5 (particles with a diameter smaller than 2.5 μm) has been associated with cardiovascular and respiratory morbidity and mortality. It has been shown that biomass burning for heat production purposes can generate large amounts of fine particles. Thus characteristics of particle emissions from biofuel combustion may be important in the assessment of health effects

Efficient performance simulation of class D amplifier output stages
Straightforward simulation of amplifier distortion involves transient simulation of operation on a sine wave input signal, and a subsequent FFT of the output voltage. This approach is very slow on class D amplifiers, since the switching behavior forces simulation time steps that are many orders of magnitude smaller than the duration of one period of an audio sine wave. This work presents a method
Digital Control of Tunneling Accelerometer
A controller for a tunneling accelerometer has two tasks: to establish tunneling and to maintain tunneling during acceleration. This paper describes the design and implementation of a digital controller that accomplishes these tasks and provides the appropriate gain switching. The control law is based on a standard configuration of an observer and state feedback. A digital controller is implemente
A simulation model of a retail distribution centre with RFID technology
This paper presents a simulation model that has been developed to analyse how the application of Radio Frequency Identification technology (RFID) affects material handling activities in a retail distribution centre. The simulation model handles both stochastic and dynamic behaviours, and describes how the receiving, picking and shipping activities will behave and perform over time when RFID tags a
