Great concern has arisen in the field of reversible data hiding encrypted images (RDHEI) due to development cloud storage and privacy protection. RDHEI is an effective technology that can embed additional after image encryption, extract error-free reconstruct original losslessly. In this paper, a high-capacity fully method proposed, which based on pixel prediction multi-MSB (most significant bi...

We study the multicast capacity of a random hybrid wireless network consisting of wireless terminals and base stations. Assume that n wireless terminals (nodes) are randomly deployed in a square region and all nodes have the uniform transmission range r and uniform interference range R = Θ(r); each wireless node can transmit/receive at Wa-bps. In addition, there are m base stations (neither sou...

Sellke, Sarah H. Ph.D., Purdue University, May 2010. Analytical Characterization of Internet Security Attacks. Major Professors: Saurabh Bagchi and Ness B. Shroff. Internet security attacks have drawn significant attention due to their enormously adverse impact. These attacks includes Malware (Viruses, Worms, Trojan Horse), Denial of Service, Packet Sniffer, and Password Attacks. There is an in...

The relationship between learner capacity and generalization, established by Vapnik’s uniform convergence framework, suggests a remarkably simple validation procedure: reject the inductive hypothesis if the learning algorithm can also store the training examples with random labels. We study the properties of this apparently coarse estimator, which can be considered as the simplest possible capa...

The present paper explores a simple approach to the question of parallel tempering temperature selection. We argue that to optimize the performance of parallel tempering it is reasonable to require that the increase in entropy between successive temperatures be uniform over the entire ensemble. An estimate of the system's heat capacity, obtained either from experiment, a preliminary simulation,...

The term HetNets (heterogeneous networks) is used to describe cellular networks in which the capacity supply is heterogeneous due to the overlaid architecture of macrocells and small-cells. In this thesis we use the term HetHetNets to refer to cellular networks in which the traffic demand is also heterogeneous due to reasons such as user spatial clustering and diversified user traffic types, in...

Minimizing SONET ADM costs in single-hub SONET/WDM ring networks via traffic grooming has been discussed in a number of recent works. Recent work [12] gives the exact minimum costs of uniform traffic in both UPSR and BLSR/2 and proves that the BLSR/2 would never be more expensive than UPSR under any traffic pattern, if all wavelengths have same capacity. In this paper we consider how to groom b...

in this paper, we propose a parametric uniform approximation method to solve np-hard absolute value equations. for this, we uniformly approximate absolute value in such a way that the nonsmooth absolute value equation can be formulated as a smooth nonlinear equation. by solving the parametric smooth nonlinear equation using newton method, for a decreasing sequence of parameters, we can get the ...

laser forming is a modern process which is mainly used for forming metals. different lasers are used in this regard that includes nd: yag and co2. in this study, forming bi-layer sheets of aluminum/ceramic by laser was investigated. furthermore, effect of uniform and gaussian heat flux distribution in different power, velocity, and beam diameters on bending angle was studied. fem simulation ind...
