We propose a novel method for performing point-feature correspondence based on a modal shape description. Introducing shape information into a low-level matching process allows our algorithm to cope easily with rotations and translations in the image plane, yet still give a dense correspondence. We also show positive results for scale changes and small skews, and demonstrate how reflectional sy...

It is known that if neutrino is a Dirac fermion with magnetic moment, then νL → νR → νL transition of supernova neutrinos may occur. The first stage of such transition is due to the neutrino spin flip inside the hot dense supernova core, while the second one – due to the neutrino spin precession in the galactic magnetic field on the way from the supernova to terrestrial detectors. This can resu...

In this paper, we carried out a laboratory experiment to study changes in canopy reflectance of Tamarugo plants under controlled water stress. Tamarugo (Prosopis tamarugo Phil.) is an endemic and endangered tree species adapted to the hyper-arid conditions of the Atacama Desert, Northern Chile. Observed variation in reflectance during the day (due to leaf movements) as well as changes over the ...

In this paper, we investigate a multiple-input multiple-output (MIMO) system with simultaneous information detection (ID) and energy harvesting (EH) receiver. This pointto-point system operates in the vicinity of active interfering nodes. The receiver performs power splitting where a portion of received signal undergoes analog energy harvesting circuitry. Further, the information content of the...

Resonance Raman spectra of rhodium trimers (Rh3) in argon matrices have been obtained for the first time. Our samples are prepared by neutralizing a mass-filtered beam of trimer ions. Although the absorption spectrum of our optically thin samples failed to show any obvious transitions, a rich Raman spectrum was found for laser excitation wavelengths between 545 nm and 593 nm. Three fundamentals...

To observe blood B-type natriuretic peptide (BNP) level changes and the clinical implications in different periods and different cardiac pacing modes, the BNP levels of 105 patients with permanent cardiac pacing were assayed before pacemaker implantation and 1 day, 1 week, 1 month, 3 months, 6 months, and 9 months postoperatively. BNP level changes were compared in different periods and during ...

In this report the effects of using sonification when performing movements in 3D space are explored. User studies were performed where participants had to repeatedly move their hand toward a target. Three different sonification modes were tested where the fundamental frequency, sound level and sound rate were varied respectively depending on the distance to the target. The results show that the...

The monolithic integration of enhancementand depletion-mode (Eand D-mode) high electron mobility transistors (HEMTs) lattice-matched to InP is of interest in the area of circuits for low power, high speed communications. When compared to circuits implemented in depletion-mode @-mode) only technology, circuits implemented in ED-mode technology enjoy a number of advantages. D-mode only circuits r...

Nd:YAG laser pumped at high energy level with milliseconds pulses and passive Q-switched with F~' colour centers in LiF crystals vas investigated. Q-switched pulse energy, pulse length, repetition rate and peak power are investigated in various working conditions.

We propose a new model for distributed programming , called Associative Broadcast, that achieves a high level of communication abstraction by using as its fundamental mode of communication a form of logical broadcast. Each message contains a predicate that speciies the local states of the objects that are to receive the message, rather than their identi-ers. Message delivery is asynchronous and...
