Fueling Tomorrow: Scenario Planning for the Future of Gas Stations
Business Strategy and the Environment, EarlyView.ABSTRACT Transport electrification is reshaping the service infrastructures that mediate everyday mobility, yet most electrification scenario studies remain macrolevel and offer limited insight into how incumbent forecourt (gas‐station) networks can adapt under deep uncertainty.

A Construction Method of (2, 3) Visual Cryptography Scheme
IEEE Access, 2020 Visual cryptography scheme (VCS) shares a binary secret image into multiple shadows, stacking qualified set of shadows will decode the secret image without computer resources.

A Recursive Threshold Visual Cryptography Scheme [PDF]
, 2008 This paper presents a recursive hiding scheme for 2 out of 3 secret sharing. In recursive hiding of secrets, the user encodes additional information about smaller secrets in the shares of a larger secret without an expansion in the size of the latter ...

Transformation Teams Leading the Hispanic‐Serving Institutions Movement at HSI Community Colleges
New Directions for Community Colleges, EarlyView.ABSTRACT The Department of Education defunded discretionary grant programs for enrollment‐based minority‐serving institutions (MSIs) on September 10, 2025, yet Hispanic‐serving institutions (HSIs) still exist and must continue to adapt to their growing population of Latine/x students.

Weighted Threshold Secret Image Sharing [PDF]
, 2009 Given a secret image I, a threshold r, and a set of n ( ≥ r) participants P = {1, 2, ... , n} with a set of weights W = {w 1, w 2, ... , w n } where w i is the weight (which indicates the degree/rank of importance) of participant i and we assume that w 1 ≤ w 2 ≤ ... w n . The idea of weighted threshold secret image sharing encodes I into n shadows S 1,

PYTHON IMPLEMENTATION OF VISUAL SECRET SHARING SCHEMES [PDF]
Visual secret sharing schemes (VSS) represent an important concept of visual cryptography. They permit the sharing of a secret image between multiple participants so that only authorized groups can recover the secret.

A partial envelope approach for modelling multivariate spatial‐temporal data
Canadian Journal of Statistics, EarlyView.Abstract In the new era of big data, modelling multivariate spatial‐temporal data is a challenging task due to both the high dimensionality of the features and complex associations among the responses across different locations and time points.
