To better understand the biology of extinct animals, experimentation with extant animals and innovative numerical approaches have grown in recent years. This research project uses principles of soil mechanics and a neoichnological field experiment with an African elephant to derive a novel concept for calculating the mass (i.e., the weight) of an animal from its footprints. We used the elephant...

The trend is towards having smaller and smaller mobile devices, also called small-footprint devices, allowing nomadic users to access the same services as with the static computers from virtually anywhere and at any time. The idea of having software agents running on smallfootprint mobile devices sounds an attractive way of delivering services for nomadic users. One of the biggest problems is t...

Objective. The purpose of this study is to describe the three-dimensional morphometry of the brachialis muscle at its distal attachment to the ulna. Methods. Fifty cadaveric elbows were dissected and the brachialis distal insertion was isolated on the ulna bone and probed with a three-dimensional digitizer, to create a three-dimensional model of the footprint. Measurements and analysis of each ...

One of the main advantages of the Gantry-Tau machine is a large accessible workspace/footprint ratio compared to many other parallel machines. The design presented in this paper achieves a workspace/footprint ratio of more than 2.7 with fixed length links, which is high for a PKM. Typical PKMs, for example the Delta robot, has a ratio less than one. Optimisation schemes are typically used in or...

In this study, multi-harmonic voltage reflections are analyzed for compact power amplifiers that can be integrated into micro-sized radio units. By combining impedances at DC and harmonic frequencies throughout the transmission lines of power amplifier circuits, this method is used to reduce analytically the footprint of these circuits. Further, a cost function that takes the occupied area and ...

A systematic analysis of green-house gases emission (carbon footprint) and primary energy consumption (energy footprint) of prefabricated industrial buildings during their entire life cycle is presented. The life cycle assessment (LCA) study was performed in a cradle-to grave approach: site-specific data from an Italian company, directly involved in all the phases from raw material manufacturin...

In the context of 3D reconstruction of wide urban areas, the use of building footprints has shown to be of great help to achieve both robustness and precision. These footprints however often present inconsistencies with the data (more than one building in the footprint, inner courts, superstructures...) This paper presents a fast and efficient algorithm to enhance the building footprint databas...

Recently, a high frame rate (HFR) imaging method based on limited diffraction beam (LDB) theory has been developed. In this method, a twodimensional (2D) or three-dimensional (3D) image is constructed with a single plane wave transmission and thus a theoretical frame rate of 3750 frames/second can be obtained for biological soft tissues at a depth of about 200 mm. Because a plane wave is used t...

This thesis describes the development of an on-chip point-to-point link, with particular emphasis on the reduction of its global metal area footprint. To reduce itsmetal footprint, the interconnect uses a serial transmission approach. 8-bit data is sent using just two wires, through a pulse-based technique, inspired by the GasP interconnect from Sun Microsystems. Data and control signals are tr...

We show that it is practical to invert entire airborne electromagnetic (AEM) surveys to 3D conductivity models with hundreds of thousands of cells within a day on a workstation. We have exploited the fact that the area of the footprint of an AEM system is significantly smaller than the area of an AEM survey to develop a robust 3D inversion method which uses a moving footprint. Our implementatio...
