Sound in the landscape is an important and often-ignored aspect of human experience. In urban landscapes, seemingly cacophonous sounds can create a symphony, combining beloved nature humans with often less desirable, but no important, traffic sirens. The work this thesis puts that its relationship to landscape, under microscope. Investigations into theories composers John Cage R. Murray Schafer...

Localization of sound sources is a central aspect of auditory processing. A unique feature of mammals is the smooth, tonotopically organized extension of the hearing range to high frequencies (HF) above 10kHz, which likely induced positive selection for novel mechanisms of sound localization. How this change in the auditory periphery is accompanied by changes in the central auditory system is u...

In the society increasingly concerned with the erosion of privacy, privacy-preserving techniques are becoming very important. Secret handshakes offer anonymous and unobservable authentication and serve as an important tool in the arsenal of privacy-preserving techniques. Relevant prior research focused on 2-party secret handshakes with one-time credentials, whereby two parties establish a secur...

OBJECTIVE The aim of this study was to analyze the impact of green tea on dentin erosion. MATERIALS AND METHODS Twelve extracted sound human premolars were immersed in Coca Cola with a pH of 2.8 for 5 minutes. The surface microhardness was measured with a Knoop diamond under a load of 50gr/10s. The teeth were immersed in green tea (Camellia sinensis) solution for one minute. The microhardness...

The objective of this study was to determine the spectral characteristic of nectar-producing flowers visited by nectarivorous birds in urban areas. This study was carried out in the central area of the city of Taubaté, in the northeast of the State of São Paulo. The sample areas included green areas, such as squares and parks, and the vegetation of streets and avenues. Twelve plant species were...

Caterpillar defenses have been researched extensively, and, although most studies focus on visually communicated signals, little is known about the role that sounds play in defense. We report on whistling, a novel form of sound production for caterpillars and rare for insects in general. The North American walnut sphinx (Amorpha juglandis) produces whistle 'trains' ranging from 44 to 2060 ms in...

Artificial light owns a rapid-expanding pattern, which may disrupt the sleep behaviors of birds roosting in illuminated urban areas. Whether birds’ would variably be affected by with different wavelengths or intensities has not been broadly explored, and species Eastern China have rarely investigated. The study chose Chestnut buntings that are common migratory flying via as subjects investigate...

This paper proposes a new method of Visual Secret Sharing using Zigzag Scan approach. Non-expanded shares are generated by this scheme. This overcomes the drawback of Hilbert Curve approach, that is, the input should be a square image of size which is an integral power of 2.
