Performance studies point to the fact that in an OBS network, the link utilization has to be kept very low in order for the burst loss probability to be within an acceptable level. Various congestion control schemes have been proposed, such as the use of converters, fiber delay lines, and deflection routing. However, these schemes do not alleviate this problem. It is our position that in order ...

This paper addresses the problems and threats associated with verification of integrity, proof of authenticity, tamper detection, and copyright protection for digital-text content. Such issues were largely addressed in the literature for images, audio, and video, with only a few papers addressing the challenge of sensitive plain-text media under known constraints. Specifically, with text as the...

The present manuscript describe simple, sensitive, rapid, accurate, precise and cost effective First derivative spectrophotometric zero crossing method for the simultaneous determination of Tolperisone and Paracetamol in combined dosage form. The utility of first derivative data processing program is its ability to calculate unknown concentration of components of interest in a mixture containin...

Time or money? That is a question! In this paper, we consider dilemma in the pricing regime, which try to find optimal scheme for identical items with heterogenous time-sensitive buyers. We characterize revenue-optimal solution and propose an efficient algorithm it Bayesian setting. Our results also demonstrate tight ratio between value of wasted time seller's revenue, as well that two common-u...

In this paper a novel filtering design intended for the impulsive noise removal in color images is presented. The described scheme utilizes the rank weighted cumulated distances between the pixels belonging to the local filtering window. The impulse detection scheme is based on the difference between the aggregated weighted distances assigned to the central pixel of the window and the minimum v...

Conventional criticality-based quantum metrological schemes work only at zero or very low temperature because the uncertainty around phase-transition point is generally erased by thermal fluctuations with increase of temperature. Such an ultralow-temperature requirement severely restricts development critical metrology. In this paper, we propose a thermodynamic-criticality-enhanced sensing scen...

Long-distance air travel requires fuel with a high specific energy and density. There are no viable alternatives to carbon-based fuels. Synthetic jet from the Fischer-Tropsch (FT) process, employing sustainable feedstocks, is potential low-carbon alternative. A number of synthetic production routes have been developed, using range feedstocks including biomass, waste, hydrogen captured carbon di...

We study the recently introduced notion of a simulation-sound trapdoor commitment (SSTC) scheme. In this paper, we present a new, simpler deenition for an SSTC scheme that admits more eecient constructions and can be used in a larger set of applications. Speciically, we show how to construct SSTC schemes from any one-way functions, and how to construct very eecient SSTC schemes based on speciic...
