This paper analyzes civil litigation between a plaintiff and a defendant who exert costly effort in a tournament game. In the unique Nash equilibrium the litigant with the stronger case is more likely to win, but there is distortion in the sense that the equilibrium probability of success is closer to 0.5 than the prior is. A cost-shifting rule determines the proportion of the winner’s costs re...

Synthesis of NH-1,2,3-triazoles using an efficient, novel and easily recoverable PPy/Cu( ii ) nanocomposite.

In this paper, a scheme that has tamper proofing and recovery abilities is proposed. With the specific DCT frequency coefficients taken as the characteristic values, which are embedded into the least significant bits of the image pixels, it is used to provide proof of image integrity. If the image is tampered, the embedded characteristic values that are affected will be changed accordingly and ...

A network multicomputer is a multiprocessor in which the processors are connected by general-purpose networking technology, in contrast to current distributedmemory multiprocessors where a dedicated special-purpose interconnect is used. The advent of high-speed general-purpose networks provides the impetus for a new look at the network multiprocessor model, by removing the bottleneck of current...

This work deals with a facility location problem in which location and allocation (transportation) policy is defined in two stages such that a first-stage solution should be robust against the possible realizations (scenarios) of the input data that can only be revealed in a second stage. This solution should be robust enough so that it can be recovered promptly and at low cost in the second st...

In recent years the explosion in the volumes of data being stored online has resulted in distributed storage systems transitioning to erasure coding based schemes. Local Reconstruction Codes (LRCs) have emerged as the codes of choice for these applications. An (n, r ,h,a,q)-LRC is a q-ary code, where encoding is as a two stage process. In the first stage, h redundant parity symbols are generate...

Few of current video watermarking algorithms can prevent HD videos from unauthorized copying after the production is distributed. This paper proposes a recoverable video watermarking algorithm in DCT domain to achieve this goal. Watermark is first split and modulated by CDMA. Then, after applying boundary detection, frames in one shot are divided into blocks. Finally, watermark is embedded into...

Negative stiffness honeycomb materials are comprised of unit cells that exhibit negative stiffness or snap-through-like behavior. Under an external load of small magnitude, a negative stiffness honeycomb exhibits large effective elastic modulus, equivalent to those of other standard honeycomb topologies. When the external load reaches a predetermined threshold, the negative stiffness cells begi...
