An RTP profile (SAVP) for secure real-time communications and another profile (AVPF) to provide timely feedback from the receivers to a sender are defined in RFC 3711 and RFC 4585, respectively. This memo specifies the combination of both profiles to enable secure RTP communications with feedback. Ott & Carrara Standards Track [Page 1] RFC 5124 February 2008 Table of

The control process for a chaotic system as proposed by Ott, Grebogi and Yorke (OGY) is investigated for systems with a one-dimensional Poincaré map. The calculation of the Poinaré map for the controlled system turns out to be an instructive method to analyze the mechanism of OGY control. We introduce the notion of a region of immediate capturing, characterizing the maximum control region that ...

In recent years, several important trends can be observed in the delivery of multimedia services: (i) increase of video bandwidth, necessitating content placement, prioritization, scheduling, and cloud-assisted streaming; (ii) increased importance of Quality of Experience (QoE) for the end user; (iii) complex multimedia consumption patterns (interactive multiple screen applications, non-linear ...

We study a model of interbank credit where physical and informational frictions limit the opportunities for intertemporal trade among banks and outside investors. Banks obtain loans in an over-the-counter market (involving search, bilateral matching, and negotiations over the terms of the loan) and hold assets of heterogeneous quality that in turn determine their ability to repay those loans. W...

We study the power conservation and disseminating reliability problem in precision agriculture applications in this paper. Precision agriculture needs to accurately evaluate farming environment, and soil monitoring is an important part of this effort. Soil measurement requires soil sensors being buried deep enough so as to avoid plowing and other mechanical activities. Due to dielectric loss, r...

Evidence has accumulated in recent years of the occurrence, in certain nonlinear systems. of strange nonchaotic attractors. that is attractors whose geometrical character is not simple, but on and near to which the exponential divergence of trajectories. characteristic of chaotic behaviour. does not occur. This behaviour has implications for predictability; small errors in initial conditions gr...

The recent credit crisis has heightened the awareness of credit risk among financial markets’ regulators and participants. However, despite the public discussion on centralized processing systems for the off-exchange traded (Over-The-Counter, OTC) transactions no research has been conducted on the factors that could explain their adoption among market participants. With this study, an attempt i...

The crisis of 2007-8 was a crisis of collateral. Since then, financial market participants – particularly in the euro area and the United States – have shown an increased appetite for secured lending. In short-term bank funding markets, there has been a pronounced shift towards repurchase arrangements. And covered bonds have gained in popularity in long-term funding markets. The cyclical flight...

The control method of Ott, Grebogi, and Yorke (OGY) is used to stabilize the unstable periodic orbits of a chaotic relay system. Small variations in the height of the relay output are used as control input. The influence of the control activation bound is studied in detail via the one-dimensional Poincare map of the controlled system. The reduced sensitivity of the multi-step OGY method for hig...

In this paper, we model price dispersion effects in over-the-counter (OTC) markets to show that in the presence of inventory risk for dealers and search costs for investors, traded prices may deviate from the expected market valuation of an asset. We interpret this deviation as a liquidity effect and develop a new liquidity measure quantifying the price dispersion in the context of the US corpo...
