Although Lemur catta persists in many habitat types in southern Madagascar, its ecology has been primarily studied within gallery forests. We compare plant food selection and properties for ring-tailed lemurs in the spiny and gallery forests over the synchronized lactation period (September to March) that includes both the dry and wet seasons. We found no significant habitat-specific difference...

Ordinary labels on museum or gallery objects compromise the competing demands of diiering visitors, curators and educators. Although adaptive hypermedia systems ooer a degree of personalisation to the visitor, they do not go as far as they might. Intelligent labelling can achieve higher levels of personalisation, and this is desirable because it leads to a more coherent and educational visit, a...

Art gallery problems are, broadly speaking, the study of the relation between the shapes of regions in the plane and the number of points needed to guard them. These problems have been extensively studied over the last decade and have found different type of applications in practical situation. Normally the number of sides of a polygon or the general shape of the polygon is used as a measure of...

sensor which uses whispering gallery modes (WGMs) in dielectric microspheres for biomolecular detection. The WGMs are excited by evanescent coupling to an etch-eroded single mode optical fiber. WGM resonance positions are detected as Lorentzian dips in the intensity of the fiber-transmitted light. The polarization of molecules interacting with the evanescent field of the WGM on the microsphere ...

The Habitable Zone Gallery is a new service to the exoplanet community that provides habitablezone (HZ) information for each of the exoplanetary systems with known planetary orbital parameters. The service includes a sortable table with information on the percentage of orbital phase spent within the HZ, planetary effective temperatures, and other basic planetary properties. In addition to the t...

The spectral shift response of optical whispering-gallery modes due to the adsorption and desorption of water molecules into a SiO2 nano-coating is investigated. This coating is applied to a silica microsphere and optical-shift measurements are made at a very low humidity level (<10%). The micro-optical coupling system is incorporated into a sealed vacuum chamber for controlled humidity testing...

Highly sensitive sensing is one of the most important applications of whispering-gallery-mode (WGM) microresonators, which is usually accomplished through a tunable continuous-wave laser sweeping over a whispering-gallery mode with the help of a fiber taper in a relative slow speed. It is known that if a tunable continuous-wave laser sweeps over a high quality whispering-gallery mode in a fast ...

Face recognition in surveillance systems is important for security applications, especially in nighttime scenarios when the subject is far away from the camera. However, due to the face image quality degradation caused by large camera standoff and low illuminance, nighttime face recognition at large standoff is challenging. In this paper, we report a system that is capable of collecting face im...

Predicting the performance of a biometrics is an important problem in a real-world application. In this paper, we present a binomial model to predict both the fingerprint verification and identification performance. The match and non-match scores are computed, using the number of corresponding triangles as the match metric, between the query and gallery fingerprints. The triangles are formed us...

Providing engaging interpretation resources for museum and gallery visitors may have a great impact on the overall museum visiting experience all by assisting museums maintain long-term relationships with their public. This paper focuses on the ways through which AR can be employed in museum and gallery settings as an interpretation medium. It also introduces a new generation of multimedia guid...
