In this paper the problem of dynamic selfreconfiguration of a class of modular robotic systems referred to as metamorphic systems is examined. A metamorphic robotic system is a collection of mechatronic modules, each of which has the ability to connect, disconnect, and climb over adjacent modules. We examine the near-optimal reconfiguration of a metamorphic robot from an arbitrary initial confi...

We have studied the syn-kinematic very low-grade metamorphism in a polyphase Variscan deformed region using X-ray diffraction techniques. Two phases of regional metamorphism are related to their respective episodes of penetrative deformation in the southern Central Iberian Zone. The data obtained suggest that the rocks did not reach metamorphic equilibrium, but strain favoured the progress of m...

comparison between our approach and commercial virus scanners. I would also like to thank my friends and schoolmates for their technical and emotional support. I want to thank Yue Wang for performing the virus scanning, and Peter Hey for repairing my hard disk after it crashed at the most critical moment. Finally I want to thank my family for their understanding and support throughout my five y...

We present for the first time an un-buffered WBand oscillator on a Metamorphic HEMT GaAs substrate. The oscillator has an output power of +1.5 dBm and a phase noise of -101 dBc/Hz at a 1 MHz offset. This oscillator will be part of an integrated monolithic front end. Index Terms – Metamorphic HEMT, HEMT, Oscillator, millimeter wave, front end.

Anuran metamorphosis, the transition from aquatic larvae to terrestrial juveniles, is accompanied by significant morphological, physiological, and behavioral changes. Timing of metamorphosis and final size, which can influence adult fitness, may depend on sufficient energy accumulated during the larval period to support metamorphosis. However, only two species of anurans have been examined for ...

The Tauride Belt Ophiolites in southern Turkey are located on both sides of the E–Wtrending, Mesozoic Tauride carbonate platform. They comprise the Lycian, Antalya, Beyşehir, Mersin, Alihoca and Pozantı-Karsantı ophiolites from west to east. Each ophiolite has a metamorphic rock unit either at the base of the peridotites or in the mélange units. The metamorphic sole rocks generally consist of a...
