The research projects are:
Optoacoustic methods applied to optically and acoustically scattering media. - ref no. 1656-09
The optoacoustic technique is becoming an important tool in characterizing complex materials. This project aims for increasing the understanding of the optical to acoustical energy conversion process and how that process can be used in material characterization. This includes detection of the volumetric size and shape of the photoacoustic source as well as the influence of laser power. The project also includes studies to develop the technique towards tomography applications as well as performing theoretical studies on optical and acoustical fields in scattering media. The process of calculating material properties from measurement data is given specific attention.
Candidates should have a background in engineering physics or similar and have an interest in applied optics.
Researchers to contact for further information are Dr. Torbjörn Löfqvist or Prof. Jerker Delsing.
Electromagnetic moisture metering in granular magnetic and electric conductive materials. - ref no. 1658-09
Aquametry, or moisture metering, in complex granular materials has important applications within the mineral industry. The proposed project includes electromagnetic modeling, from first principles, and simulation of granular materials electromagnetic properties. These studies will be experimentally verified. Through simulations, evaluate and optimize different sensing element designs as well as design and build the electronics for an integrated moisture sensor. The aim of the project is to bring the technique forward towards an embedded device.
Candidates should either have a background in engineering physics, with an interest in electronics, or electrical engineering. Experience from finite element/finite difference software for electromagnetic field simulations is not required but is a plus.

New high frequency ultrasonic transducers ref no. 1660-09
Based on optoacoustic excitation techniques a new high frequency ultrasound transducer technique will be investigated. The foundation of the project is to model, from first principles, and experimentally verify the acoustic properties of the transducer. We will also investigate how these ultrasonic transducers can be manufactured directly on circuit boards possibly using sequential copper building techniques in combination with integrated laser diodes.
Candidates should have good knowledge in physics, electronics and acoustics. Preferably also an interest in a practical realization of the transducer at micro scale.

SOA-enabled wireless sensor networks - ref no. 1662-09
The use of SOA (Service Oriented Architecture) on wireless sensors can enable a true plug 'n play technology for wireless sensor networks. However, the use of SOA might not be feasible on resource-constrained embedded systems, and can result in a (too) high overhead in terms of memory resources, computational power, and energy usage. It is therefore important to develop an architecture that can support SOA on small systems, still being able to communicate with standardized services on the Internet.

Antenna designs for Global Navigation Satellite Systems (GNSS) - ref no. 1664-09
The area of GNSS is expanding rapidly. A primary feature is the addition of new signals at existing and new frequencies. As a result, GNSS receivers are subject to challenges in the antenna/receiver design to enable a constant phase center and minimize the impact of multipath and interference. The goal of this research effort will be to explore the future antenna design for GNSS. The work will include antenna/receiver designs both for leveraging the new available signals and for new applications of GNSS (e.g. bistatic radar).
Candidate would have background in signal processing, particularly related to GNSS, as well as antenna/electromagnetics, and have a interest in developing both of these areas. The candidate should be able to work with both simulations and RF laboratory experimental validation of antenna designs.
Researchers to contact for further information are Dr. Dennis Akos, Dr. Jonny Johansson, or Prof. Jerker Delsing.
Artificial cortical networks - ref no. 1665-09
The research will be focused on modelling and simulating functions of the human brain using artificial cortical networks, which are modular and hierarchically organized architectures with both bottom-up and top-down connections. Examples of functions to be studied are sensory integration, attention, awareness and context dependent information processing.
The candidate should either have a background in computer science, engineering physics, space- or electrical engineering

Highly efficient power electronics for hybrid drivelines with reduced EM emissions - ref no. 1663-09
The standard method to achieve high energy efficiency in the power electronics of a hybrid driveline is to use pulse width modulation (PWM) i.e. the output voltage of the power electronics is switched on and off with a frequency much higher than the required frequency response of the driveline. The drawback of this is that it creates a lot of transients which often creates serious EMC problems. The transients can even lead to catastrophic failure of the driveline itself.
The project is about how this type of power electronics should be modeled to enable correct design and simulation of it from the start instead of the present situation with different rule of thumb fixes afterwards to get it behave as wanted.
Candidates should have good knowledge in electronics, electromagnetics, embedded systems and embedded system software. Strong knowledge in electronics simulation and modeling is credited.
Researchers to contact for further information are Prof. Kalevi Hyyppä, Prof. Jerker Delsing, or Dr. Jonas Ekman.
Reactive analog design - ref no. 1661-09
The research area is mixed signal electronics specializing in the design of low power electronics on silicon and its applications in reactive analog design. One specific use of the reactive design approach is the development of time measuring, non-uniform sampling A/D converters, which are triggered by an event rather than a traditional time interval. Analog buffer and memory structures are also included in the area.
Candidates should have good knowledge in electronics. Strong knowledge in electronics simulation and modeling is credited.
Researchers to contact for further information are Dr. Jonny Johansson, Prof. Kalevi Hyyppä or Prof. Jerker Delsing.
Program analysis and verification - ref no. 1659-09
It is vital that software developed for embedded systems can be executed under limited time and memory constraints. Guarantees of such a safe execution may be derived at compile-time by means of rigorous methods of static program analysis and verification. EISLAB is looking for a PhD candidate to pursue research in static analysis of object-oriented, reactive, functional programming language Timber. The research will cover theoretical studies, development of analysis techniques, as well as implementing experimental software.
Candidates should have background in computer science or computer engineering.

SW based EMC control of embedded systems - ref no. 1657-09
The software (SW) controls the actions of embedded electronics system. Thus, SW plays a central role in the generation of electromagnetic disturbances from embedded systems. We like to explore the capability of designing SW with very tight real time requirements thus enabling good EMC performance. For the purpose, the real time SW modeling tool Timber will be combined with the EM modeling method PEEC to enable prediction of EMC properties of an embedded system design.
Candidates should have good knowledge in electromagnetics, electronics, embedded system and embedded system software. Strong knowledge in EM modeling and real time software design is credited.

Integration of non-linear devices in EM modeling - ref no. 1655-09
With the PEEC approach, an electromagnetic problem is converted to the circuit domain and solved in terms of circuit equations. In this project, the incorporation of non-linear devices like transistor and diode models with the PEEC models will be explored to further develop the method and allow for new application areas. This requires full control over the system of neutral delay differential equations describing the combined models.
Candidates should have good knowledge in mathematics, electromagnetics, electronics and programming.
Researchers to contact for further information are Dr. Jonas Ekman or Prof. Jerker Delsing.
Complex material modeling for electromagnetic solvers - ref no. 1654-09
The PEEC approach is a relatively new method to solve Maxwell’s equations in the time and frequency domain and the possibilities to model different types of complex materials has not been widely explored. This project aims at extending the modeling capabilities of the solver by new electromagnetic models for frequency dependent dielectric materials and anisotropic materials.
Candidates should have good knowledge in mathematics, electromagnetics, electronics and programming.
Researchers to contact for further information are Dr. Jonas Ekman or Prof. Jerker Delsing.
Ultrasonic mass flow meter ref no. 1653-09
Volumetric flow measurement is not sufficient when the density of a liquid changes too much. The idea is to combine transit time ultrasonic volumetric flow meters with the idea of an ultrasonic densitometer implemented within the same transducers. The research aims at optimizing the transducers but also at processing the signals both in the time and frequency domain to reduce uncertainties associated with the measurements.
The candidate should either have a background in engineering physics, space- or electrical engineering.
Researchers to contact for further information are Dr. Jan van Deventer, Prof. Jerker Delsing, or Dr. Torbjörn Löfqvist.
