A Markowitz-modell a kvadratikus programozás tükrében

, 2019
Szakdolgozatom témáját az optimális portfóliók Markowitz-féle modellje motiválta. Ez a modell azért jelentős, mert a kockázatot a tapasztalatokkal jól egybevágó módon építi be a piaci befektetések várható hozamának vizsgálatába. Maga a modell matematikai

Friction and vibration generated during sliding over bare skin correlate with perceived smoothness and moistness

International Journal of Cosmetic Science, EarlyView.
A tactile sensor with a probe replicating a fingerprint quantified skin texture by measuring vibration and friction. Regression analysis linked smoothness and moistness perceptions with high‐frequency vibration amplitude and friction. These findings support the objective assessment of skin texture, enhancing product evaluation consistency and bridging ...

Rational determination of real‐life UV exposure across latitudes: An extended Diffey‐based model integrating behavioural factors

International Journal of Cosmetic Science, EarlyView.
This study models real‐life UVB and UVA exposure across latitudes and seasons using an extended Diffey framework with behavioural corrections. Findings reveal predictable dose patterns and support pragmatic SPF and UVA‐PF caps, offering a quantitative basis for realistic photoprotection and regulatory discussion.
