QBD*: a graphical query language with recursion [PDF]
IEEE Transactions on Software Engineering, 1990 A system to query databases using diagrams as a standard user interface is proposed. The system, called Query by Diagram* (QBD*), makes use of a conceptual data model, a query language on this model, and a graphical user interface. The conceptual model is the entity-relationship model. The query language, whose expressive power allows recursive queries,

Tree Structured QBD Markov Chains and Tree‐Like QBD Processes [PDF]
Stochastic Models, 2003 Abstract In this paper, we show that an arbitrary tree structured quasi‐birth–death (QBD) Markov chain can be embedded in a tree‐like QBD process with a special structure. Moreover, we present an algebraic proof that applying the natural fixed point iteration (FPI) to the nonlinear matrix equation V = B + ∑ s=1 d U s (I − V)−1 D s that solves the tree ...

Quality by design based development of nanostructured lipid carrier: a risk based approach
Exploration of Medicine, 2022 The aim of this review is to discuss the development of nanostructured lipid carrier (NLC) by the application of quality by design (QbD). QbD started with the evolution of the quality concept and slow adaptation of quality guidelines, which has now ...

Reconciling Quality by Design and Transdermal Product Development
Pharmaceutics, 2020 Since my first exposure to the acronym ‘QbD’ more than ten years ago, I have been trying to understand exactly what QbD is and how I might incorporate its teachings into my twenty-odd years of experience developing transdermal systems. I feel

Renormalization in Quantum Brain Dynamics
AppliedMath, 2023 We show renormalization in Quantum Brain Dynamics (QBD) in 3+1 dimensions, namely Quantum Electrodynamics with water rotational dipole fields. First, we introduce the Lagrangian density for QBD involving terms of water rotational dipole fields, photon ...
