This memo describes how to carry real time text conversation session contents in RTP packets. Text conversation session contents are specified in ITU-T Recommendation T.140. Two payload formats are described. One for transmitting text on a separate RTP session dedicated for the transmission of text, and one for transmitting audio and text data within one single RTP session. This RTP payload des...

This paper explores possibility of detecting intrusions into computer networks using network packet payload analysis. Quick overview of current IDS state of the art is given. Issues with IDS are explained. Integrated approach to IDS building is suggested. Anomaly detection process improvements are recomended. Current prevailing methods for network intrusion detection based on packet meta data, ...

Network steganography is a covert communication technique that uses redundancies in network protocols to transfer secret information. The retransmission-based steganography (RSTEG) embeds covert messages into the payload field of the intentionally retransmission packets. So its capacity is higher than most of the existing methods. Because TCP checksum field of the original packet is different f...

In this paper, we address the cooperative towing of payloads by multiple mobile robots in the plane. Robots are attached to a planar object or a pallet carrying a payload by cables. Coordinated motion by the robots allow the payload to be manipulated through a planar, warehouse-like environment. We formulate a quasi-static model for manipulation and derive equations of motion that yield the mot...

Microelectromechanical systems (MEMS) deformable mirrors (DMs) can provide high-precision wavefront control with a small form-factor, low power device. This makes them key technology option for future space telescopes requiring adaptive optics high-contrast imaging of exoplanets coronagraph instrument. The Deformable Mirror Demonstration Mission (DeMi) CubeSat payload is miniature telescope des...

The secure data transmission over internet is achieved using Steganography. In this paper High Capacity and Security Steganography using Discrete wavelet transform (HCSSD) is proposed. The wavelet coefficients of both the cover and payload are fused into single image using embedding strength parameters alpha and beta. The cover and payload are preprocessed to reduce the pixel range to ensure th...

This document specifies a real-time transport protocol (RTP) payload format to be used for Adaptive Multi-Rate (AMR) and Adaptive MultiRate Wideband (AMR-WB) encoded speech signals. The payload format is designed to be able to interoperate with existing AMR and AMR-WB transport formats on non-IP networks. In addition, a file format is specified for transport of AMR and AMR-WB speech data in sto...

We demonstrate here the effective delivery of a dye payload into cells using 2-nm core gold nanoparticles, with release occurring via place exchange of glutathione onto the particle surface. In vitro experiments demonstrate effective release of drug analogues upon addition of glutathione. Cell culture experiments show rapid uptake of nanoparticle and effective release of payload. The role of gl...
