bstract. A new steganographic method for data hiding in jig swap uzzle images is proposed. First, a color image is taken as input and ivided into blocks. Second, each block is rearranged to a new poition according to the secret data and a stegokey. The resulting mage is a perfect jig swap puzzle. The original image is needed for xtracting the secret data. Under the assumption that the receiver ...

We introduce the swap-or-not shuffle and show that the technique gives rise to a new method to convert a pseudorandom function (PRF) into a pseudorandom permutation (PRP) (or, alternatively, to directly build a confusion/diffusion blockcipher). We then prove that swap-or-not has excellent quantitative security bounds, giving a LubyRackoff type result that ensures security (assuming an ideal rou...

The qubit SWAP gate has been shown to be an integral component of quantum circuitry design. It permutes the states of two qubits and allows for the storage quantum information, teleportation of atomic or ionic states, and is a fundamental element in the circuit implementation of Shor’s algorithm. We consider the problem of generalising the SWAP gate beyond the qubit setting. We show that quantu...

Current DSM-based instruments for personality disorders (PDs) limit the investigation of the course and outcome of treatment of these disorders. This study examined the validity of the Shedler-Westen Assessment Procedure-200 (SWAP-200) and the Structured Clinical Interview for DSM-IV Axis II PD (SCID-II) in a sample of forensic PD patients. Results based on 66 participants indicated that the SW...

We study online learning with the general notion of transductive regret, that is regret with modification rules applying to expert sequences (as opposed to single experts) that are representable by weighted finite-state transducers. We show how transductive regret generalizes existing notions of regret, including: (1) external regret; (2) internal regret; (3) swap regret; and (4) conditional sw...

The credit default swap has become well-known as one of the causes of the 2007-2010 credit crisis but more research is vitally needed to analyze and define its impact more precisely and help the financial market transparency. This paper uses cartesian genetic programming as a discovery tool for finding the relationship between credit default swap spreads and debts and studying the arbitrage cha...

PURPOSE: To compare the abilities of scanning laser polarimetry (SLP), optical coherence tomography (OCT), short-wavelength automated perimetry (SWAP), and frequency-doubling technology (FDT) perimetry to discriminate between healthy eyes and those with early glaucoma, classified based on standard automated perimetry (SAP) and optic disc appearance. To determine the agreement among instruments ...

The string correction problem looks at minimal ways to modify one string into another using fixed operations, such as for example inserting a symbol, deleting a symbol and interchanging the positions of two symbols (a “swap”). This has been generalized to trees in various ways, but unfortunately having operations to insert/delete nodes in the tree and operations that move subtrees, such as a “s...

The uncapacitated facility location problem aims to select a subset of facilities to open, so that the demands of a given set of customers are satisfied at the minimum cost. In this study, we present a novel multistart Drop-Add-Swap heuristic for this problem. The proposed heuristic is multiple applications of the DropAdd-Swap heuristic with randomly generated initial solutions. And the propose...
