birds, sometimes numbering in millions, can cause serious damage to grain fields. in order to find a method to accordance with environmental issues and effective in controlling these birds, in this research, the effect of sound was studied for keep birds away. the broadcast unit was developed with the following design criteria: 1) three sound levels of hawk, gas gun and sparrow distress, with f...

A diverse array of birds apparently make mechanical sounds (called sonations) with their feathers. Few studies have established that these sounds are non-vocal, and the mechanics of how these sounds are produced remains poorly studied. The loud, high-frequency chirp emitted by a male Anna's hummingbird (Calypte anna) during his display dive is a debated example. Production of the sound was orig...

Steganography is the ability to hide secret information in a cover-media such as sound, pictures and text. A new approach is proposed to hide a secret into Arabic text cover media using "Kashida", an Arabic extension character. The proposed approach is an attempt to maximize the use of "Kashida" to hide more information in Arabic text cover-media. To approach this, some algorithms have been des...

An Audio Secret Sharing (ASS) scheme is a special type of secret sharing scheme [3], which the shares of embedded messages use music as cover sound. Desmedt et al. firstly introduced the (2, 2) ASS scheme with one cover sound and also the generalized (2, n) ASS scheme with log2n different cover sounds. No only will more cover sounds overburden the human hearing system but also may become diff...

in this paper, a smart method is designed in order to classify healthy and illness ducks using their emission voice. for this purpose, firstly, the birds based on their healthy condition are divided into the different categories and then their voices are saved using a microphone and data acquisition card. gained signals were transformed from time-domain signal to frequency domain using fast fou...

In an audio secret sharing scheme, the shares are created by embedding the secret message into an audio file. The audio or the music file which is used to embed the given message is called cover sound. A 2-out-of-2 audio cryptography is a secret sharing scheme that can be used to hide a digital message into 2 shares and we can perceive the message by playing these 2 sounds simultaneously. In th...

Male and female meat chickens were reared for 28 d in blue, green, red, or white light at 30 lx and the effects on tissue growth and bird behavior recorded. Birds reared in red or white light were more active, as expressed by greater walking activity in the white light treatment and by greater floor-pecking, wing-stretching, and aggression in the red light treatment. In these two treatments, gu...
