Masters Thesis 2015-2016

Written by

Masters Thesis 2015-2016

Featuring the details of thesis projects being conducted by CAS students currently or next spring!

 

ONGOING THESIS PROJECTS

Using situation based predictive risk estimation for subject and surrounding traffic to ensure safe maneuvering of long combination vehicles (LCVs) in highway driving scenarios.

 "When driving long-combination vehicles (trucks so long and heavy that they need a special permit to be driven on roads), it is important that the driver handles the vehicle as safely as possible. This master thesis will explore methods for estimating the risks for the subject vehicle and surrounding traffic which allow safe maneuvering. This will be used both for alerting the driver of dangerous situations and autonomous driving. The work includes adaptive systems and risk analysis, and will be performed at Volvo Group Trucks Technology."

Multi-level evaluation of autonomous vehicles using agent-based transport simulation for the case of Singapore

Based on an existing large-scale agent-based simulation of Singapore (MATSIM) the impacts of autonomously driving vehicles are examined. The focus of investigation lies on the emerging choice behaviour of customers in the multi-modal public transport scenario. Different pricing scenarios and service schemes are simulated to compare the acceptance and usability of the new technology.

January until June 2016 @ ETH Singapore Center Future Cities Laboratory (FCL) - www.futurecities.ethz.ch

Presentation: mid-July 2016

Real-time optimization of traffic situation maneuvers for long combination vehicles (LCVs)

An approach to improve traffic safety and to further increase transport efficiency of LCVs is to utilize automated driving functionalities including propulsion, braking and steering. This master thesis will propose an optimization scheme which allows real-time actuation generation for highway maneuvers of LCVs. The work includes adaptive systems and programming and optimization, and will be performed at Volvo Group Trucks Technology.

Here are some tips from our director on doing thesis project. A summary of information about the master thesis: 

- Start early (i.e. now), looking for a project: talk to teachers, look for posters, search the web. I will also forward occasional project proposals. 

- The project should be CAS (or physics) related, interpreted in a wide sense. The most most important thing is that it has a solid scientific or engineering perspective. 

- You need an examiner at Chalmers. You need a supervisor at Chalmers or elsewhere, such as in a company. (Examiner and supervisor may be the same person for a local Chalmers project.)

- Typically the project should be registered at the department where the examiner is active.

- Before you start, you need to have the registration form signed by the MPA, and the examiner. There should be a short project plan which is what I need to see to approve it as a CAS thesis. 

- Don’t forget to fill in the work card once you start on the project (which implies attending other thesis presentations, etc.) 

- More information is found at the Studentportal Examensarbete

 

If you have questions or need help, you very welcome to contact the Director.

Time to think about thesis topic!

Last week Bernhard and Kolbjörn held short presentations of their research areas and proposed some thesis topics.

Those are available to you in the documents attached to this post.

Land use modeling

Written by

The awakening awareness about climate change during the last decade have increased the interest for commercial bioenergy. The food price spike in 2008 did however start a debate about the effects that bioenergy production might have on global food prices. The main connection between bioenergy and food production is through land use competition. The aim of this thesis is to create an agent based model based on an already existing conceptual equilibrium model and to compare the two models when applied on global land use competition between food and bioenergy crops. Both models turned out to give similar equilibrium states for the system. An advantage with the agent based model is that it can be used to study dynamic events. It did however prove to be highly unstable with regards to prices and quantities. In order to stabilize the system different mechanisms were introduced. The majority of these mechanisms were intended to target the uncertainty of future prices for the agents. The effects of the mechanisms varied but especially the introduction of a cost for changing production type proved to be efficient in reducing fluctuations. The results of both models show that increased bioenergy production have substantial effects on global food prices.

Schelling model

Written by

Thomas Schelling, in 1971, showed that a small preference for one's neighbors to be of the same color could lead to total segregation. He used coins on graph paper to demonstrate his theory by placing pennies and nickels in different patterns on the "board" and then moving them one by one if they were in an "unhappy" situation. Here's the high-tech equivalent. The rule this ALife model operates on is that for every colored cell, if greater than 33% of the adjacent cells are of a different color, the cell moves to another randomly selected cell.

This is my first experiment with writing computer programs to simulate interesting processes we come across in real life. There are a number of reasons why this kind of simulation is useful and I'll try to summarize what in my mind are the main ones:

  • Most modelling techniques are based on the notion that an equilibrium state is the norm, while cellular automata (CA) simulations do not have this bias.
  • Instead of trying to create a model that requires a full understanding of the highly complex outcomes of processes, CA allows us to understand the decision rules of a small number of individual actors.
  • Simulation models are very good at incorporating time and space, especially when tied to a geographic information system.
