Mixcoin is a Bitcoin mixing protocol proposed by Bonneau et al. which provides strong accountability guarantees [13]. However, in the Mixcoin protocol, the mapping from a user’s input to output address is visible to the mixing server. We modify the Mixcoin protocol to provide guarantees that the input/output address mapping for any user is kept hidden from the mixing server. In order to achieve...

This paper proposes a tonal component coding algorithm for a codec that employs a transform followed by Hu man coding, such as MPEG-2 Audio NBC (Non-Backward Compatible)[1]. After the input audio signal is mapped onto a frequency domain, the proposed algorithm withdraws local maximum components that degrade coding e ciency. By this withdrawal, the atness of the spectrum increases and the e cien...

The program environment for automatic designing of the application specific parallel architectures (liked to VLSI processor arrays) is proposed. The environment consists of three compatible programs which allow to construct and to visualize the dependence graph of algorithms given by nested loops, and then mapping of these algorithms onto corresponding processor array architectures with desired...

When primed by backward-masked, target-like stimuli, discrete responses (e.g. button presses) to simple visual targets can be slower when prime and target match (compatible) than when they do not (incompatible). The current study investigated the nature of the stimulus-response mapping underlying this negative compatibility effect (NCE). Discrete left-right responses to arrow targets were prime...

In this paper a numerical approach of the elasto-plastic problem with mixed hardening in the plane stress state, within the classical constitutive framework of small deformation, is proposed. In the formalized problem, the non-zero normal component of the strain (namely, the component in the direction perpendicular to the plane of stress) is considered to be compatible with the plane stress. We...

The aim of the present study was to investigate the modulations in amplitude of H reflexes elicited in a hand muscle, the flexor pollicis brevis, during the performance of a choice reaction time (RT) task in which this muscle was directly involved. Ten subjects were to choose between a left- or a right-thumb key-press according to the lateral location of a flash of light. The stimulus-response ...

When learning a hidden Markov model (HMM), sequential observations can often be complemented by real-valued summary response variables generated from the path of hidden states. Such settings arise in numerous domains, including many applications in biology, like motif discovery and genome annotation. In this paper, we present a flexible framework for jointly modeling both latent sequence featur...

The Locator/ID Separation Protocol (LISP) is a routing architecture that provides new semantics for IP addressing. In order to simplify routing operations and improve scalability in future Internet, the LISP uses two different numbering spaces to separate the device identifier from its location. In other words, the LISP separates the ’where’ and the ’who’ in networking and uses a mapping system...

We present our recent work on content based video (CBV) traffic modeling of variable bit rate (VBR) sources. CBV approach differs from previous works in that it is not based only on matching of various statistics of the original source, but rather on modeling and mapping its visual content into the corresponding bit rate. We show that CBV model is fully compatible with current and future compre...

To promote ontology application development, some of the technical processes should be simplified with a supportive tool and an automatic method. This work presents a method to automatically generate a database schema from OWL file to prevent schema conflicts. Moreover, a mapping configuration can be created to associate an ontology and the generated data schema within the process. This method ...
