Voice conversion (VC) emerged as a significant domain of research in the field speech synthesis recent years due to its emerging application voice-assistive technologies, such automated movie dubbing speech-to-singing conversion, name few. VC deals with vocal style one speaker another while keeping linguistic contents unchanged. Nowadays, generative adversarial network (GAN) models are widely u...

This paper will analyze the current landscape of One Time Password (OTP) and Challenge-Response algorithms. It will detail the technical and security differences between algorithms such as the OATH algorithms (HOTP, OCRA, HOTP time based), EMV CAP and the proprietary algorithms from ActivIdentity. The paper describes the most common use cases and applicability as important tools for identity as...

This paper contributes to a growing body of evidence that—when coupled with appropriate machine-learning techniques—linguistically motivated, information-rich representations can outperform one-hot encodings of linguistic data. In particular, we show that phonological features outperform character-based models using the PanPhon resource. PanPhon is a database relating over 5,000 IPA segments to...

An efficient local fuzzy color and global color-texture descriptor is proposed for content-based image retrieval. In our retrieval system, an image is represented by a set of color-clustering-based segmented regions and global color-texture descriptors. Each segmented region corresponds to an object or parts of an object and is represented by a fuzzified color feature. A fuzzy region matching s...

We report the results of an agent-based model to study the strategies that policy makers can apply to prevent the escalation of deviant behaviour in the aftermath of a disaster. Three policies are tested, namely: a reinforcement of the police power; an increase of the information available to the affected population and a combination of both policies. We test the effect of time in the implement...

The extragalactic background light (EBL), exclusive of the cosmic microwave background, consists of the cumulative radiative output from all energy sources in the universe since the epoch of recombination. Most of this energy is released at ultraviolet and optical wavelengths. However, observations show that a significant fraction of the EBL falls in the 10 to 1000 μm wavelength regime. This pr...

In the aftermath of the financial crisis, with periphery countries in the European Union even more falling behind the core countries economically, there have been quests for various kind of fiscal policies in order to revert divergence. How these policies would unfold and perform comparatively is largely unknown. We analyze four such stylized policies in an agent-based macroeconomic model and s...

This paper analyzes the security of an IBE scheme proposed by Wang in 2007. It is shown that under BDHP (which is polynomially time equivalent to BIDHP) assumption the scheme is secure in random oracle model.
