You are reading the last issue of Computational Linguistics that will appear in printed hardcopy form. The beginning of 2009 heralds a new era for the journal in at least two major respects: As of the first issue of volume 35, Computational Linguistics will be published only electronically, and it will be open access. As editor, I’d like to take this opportunity to use these last words that wil...

The optimisation of a tail-sitter UAV (Unmanned Aerial Vehicle) that uses a stall-tumble manoeuvre to transition from vertical to horizontal flight and a pull-up manoeuvre to regain the vertical is investigated. The tandem wing vehicle is controlled in the hover and vertical flight phases by prop-wash over wing mounted control surfaces. It represents an innovative and potentially simple solutio...

This paper presents a magnetic tumbling microrobot design at the micro-scale. The microrobot has a dumbbell shape whose largest dimension is about 400 μm. When subjected to an exterior predefined magnetic field, the magnetic microagent performs a tumbling motion driven by the interacting magnetic forces and momentums. The magnetic field providing driven force is generated by a coil system consi...

Smart electricity meters record the aggregate consumption of an entire building. However, appliance-level information is more useful than aggregate data for a variety of purposes including energy management and load forecasting. Disaggregation aims to decompose an aggregate signal into appliance-by-appliance information. Existing disaggregation systems tend to perform well for single-state appl...

This paper proposes a concept learning-based approach to motion control for humanoid robots. In this approach, the motion control system is implemented with decision tree learner for the acquisition of balancing property of itself body and movement and depth first search technique for the motion control based on the knowledge concerning balance and stability in the motion. Some performance resu...
