Using the Photostationary State of Arylazopyrazoles to Control Phase Transitions of Liquid Crystals

open access: yesAdvanced Functional Materials, EarlyView.
A series of new arylazopyrazole photoswitches is designed as dopants for liquid crystalline materials. Unprecedented, the distribution of photoisomers at the photostationary state upon irradiation with light of specific wavelengths (365, 460, 520 nm) is used to control the liquid crystalline phase transitions under isothermal conditions, including ...

MODELLING OF THE GAS DIFFUSION IN FLEXIBLE PIPELINES FOR OIL & GAS PRODUCTION [PDF]

open access: yesFiabilitate şi Durabilitate, 2017
This presentation describes a model used to study gas diffusion through layers of flexible pipes by time. The temperature gradient pipe is considered as temperature dependent permeability rates.

Eye gaze position before, during and after percept switching of bistable visual stimului [PDF]

open access: yes, 2015
A bistable visual stimulus, such as the Necker Cube or Rubin’s Vase, can be perceived in two different ways which compete against each other and alternate spontaneously.

Bio‐Inspired Magnetically Tunable Structural Colors from Elliptical Self‐Assembled Block Copolymer Microparticles

open access: yesAdvanced Functional Materials, EarlyView.
Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Digging Deeper into Egocentric Gaze Prediction

open access: yes, 2019
This paper digs deeper into factors that influence egocentric gaze. Instead of training deep models for this purpose in a blind manner, we propose to inspect factors that contribute to gaze guidance during daily tasks. Bottom-up saliency and optical flow

Asymmetry of the Ferroelectric Phase Transition in BaTiO3

open access: yesAdvanced Materials, EarlyView.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

AI use in the workplace. Some legal risks and challenges

open access: yesAnalele Ştiinţifice ale Universităţii "Al.I. Cuza" din Iaşi. Ştiinţe Juridice
As Artificial Intelligence (AI) advances, businesses benefit from its ability to exponentially enhance process effectiveness and efficiency, while also facing risks related to personal data protection, human dignity, and ultimately, human identity.

OPERATING THE OIL PRODUCTION FACILITY WITH SOLAR AND WIND GENERATOR [PDF]

open access: yesFiabilitate şi Durabilitate, 2017
In this paper we present an analysis of theoretical concepts very common nowadays, photovoltaic and wind turbines, but also a practical part where I presented a hybrid (photovoltaic-wind) to power a pump extraction cavitation progressive.
