Perfect contrast visual cryptography scheme
Tongxin xuebao, 2009 A perfect contrast visual cryptography scheme with the best contrast based on both the perfect black visual cryptography scheme（PBVCS） and the non-perfect black visual cryptography scheme（NPBVCS） was proposed.The proposed scheme applied simple Boolean ...

Business Strategy and the Environment, EarlyView.ABSTRACT Research on ESG controversies has expanded rapidly, but findings remain fragmented and lack a unifying perspective. This study conducts a PRISMA‐guided, framework‐based systematic review of 68 empirical articles published between 2018 and 2025 (May) to synthesize the main determinants and consequences of ESG controversies.

Electronics Letters, 1972 The Boolean matrices employed here were first described by J.O. Campeau, and were used to analyse swtiching and counting circuits. This letter describes their use in the manipulation of Boolean functions, and also a method whereby any function may be re-expressed in terms of any logical combination of its defining variables.

Tensions of Sustainability Logics: Performance of a Company Utilizing a Sustainable Business Model
Business Strategy and the Environment, EarlyView.ABSTRACT In recent years, companies have used sustainable business models to gain a competitive advantage. However, there are tensions due to the inconsistency between social, environmental, and economic logic in sustainable business models, making it difficult for companies to change. To understand the existing tensions and interactions between logics,

Business Strategy and the Environment, EarlyView.ABSTRACT The transition to a circular economy (CE) requires organizations to move beyond linear production systems toward regenerative, resource‐efficient models. For small and medium‐sized enterprises (SMEs), this transition is especially demanding due to constrained financial, technological, and human resources.

Nondeterminism and boolean operations in pda's
Journal of Computer and System Sciences, 1978 AbstractThere are nondeterministic context-free languages that cannot be expressed as a Boolean formula over deterministic context-free languages. The closure of the context-free languages under intersection does not yield closure under complementation.

Business Strategy and the Environment, EarlyView.ABSTRACT Despite growing attention to the circular bioeconomy (CBE), the steel industry currently lacks a standardised, sectoral measurement framework to facilitate a low‐carbon transition. In this study, a decision‐support framework for evaluating CBE performance in the steel industry is proposed.

FPGA-Based Implementation of Genetically Tuned Fuzzy Logic Controller (GA-FLC)
Journal of Engineering and Sustainable Development, 2012 Fuzzy Logic controller (FLC) contains three operations; the fuzzification of the inputs, the knowledge base (data base and rule base), and the defuzzification of the output. In this paper our fuzzy controller contains two inputs and one output each have
