1. Supported by FCT grant PRAXIS XXI/BD/13875/97 Abstract This paper presents an original approach to the problem of function hiding based on Error Correcting Codes and evaluates the security of this approach. The novelty of the technique consists in using Error Correcting Codes to hide functions instead of encrypting data vectors. This protocol mainly deals with the issue of secure evaluation ...

The effect of the nucleon recoil for antikaon-deuteron scattering is investigated in the framework of effective field theory. In particular, we concentrate on the calculation of the nucleon recoil effect for the double-scattering process. It is shown that the leading correction to the static term that emerges at order ξ with ξ = MK/mN vanishes due to a complete cancellation of individually larg...

BACKGROUND When scaling up lignocellulose-based ethanol production, the desire to increase the final ethanol titer after fermentation can introduce problems. A high concentration of water-insoluble solids (WIS) is needed in the enzymatic hydrolysis step, resulting in increased viscosity, which can cause mass and heat transfer problems because of poor mixing of the material. In the present study...

A new index, the estimate of the error variance, which can be used to quantify the evolution of the flow patterns when multiphase components or tracers are difficultly distinguishable, was proposed. The homogeneity degree of the luminance space distribution behind the viewing windows in the direct contact boiling heat transfer process was explored. With image analysis and a linear statistical m...

The mass transfer process is the subject of many experimental studies in chemical engineering and also one of the most commonly used processes. Unfortunately, the mechanism of this process is still not fully understood, especially when nonstandard methods of intensification of mass transfer are used. In this investigation, the use of an alternating magnetic field action (AMFs) causing mass tran...

Abstract The traditional asphalt heating methods need to consume many fossil fuels, which conflicts with carbon peaking goals and neutrality. Therefore, replacing fuels improving efficiency is a realistic severe task. This paper proposes distributed photovoltaic system based on literature review field investigation of current mixing plants. rationally uses idle workshop roofs lay solar modules ...

Particle size distribution (PSD) is one of the critical attributes crystals. PSD not only influences downstream processes but also controls final product performance in crystallization. In this work, we have used model system methanol–water-paracetamol for carrying out anti-solvent crystallization to produce paracetamol With reference a base case stirred tank, three devices connected tank with ...
