Necessary conditions involving Lie brackets for impulsive optimal control problems; the commutative case [PDF]

, 2012
In this article we study control problems with systems that are governed by ordinary differential equations whose vector fields depend linearly in the time derivatives of some components of the control.

From Bench to Bulk: Investigating Kinetics, Recyclability, and Scale‐Up of ZIF‐67

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Zeolitic imidazolate framework‐67 (ZIF‐67), a subclass of metal–organic frameworks (MOFs), has garnered considerable attention due to its high surface area, open crystal structure, tunable porosity, and potential applications in gas separation, catalysis, and carbon capture.

Application of Lyapunov's Direct Method to the Existence of Integral Manifolds of Impulsive Differential Equations [PDF]

, 1996
The present paper investigates the existence of integral manifolds for impulsive differential equations with variable perturbations. By means of piecewise continuous functions which are generalizations of the classical Lyapunov’s functions, sufficient ...

Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...

Thin and Compact Versus Thick and Porous Fouling Layers in the Emulsion Polymerization of Acrylates and Vinyl Acetates Studied In Situ With a Quartz Crystal Microbalance (QCM)

Journal of Applied Polymer Science, EarlyView.
ABSTRACT Building on a quartz crystal microbalance with dissipation monitoring (QCM‐D), fouling in emulsion polymerization was compared between acrylate dispersions stabilized with a mobile, anionic surfactant and dispersions of poly(vinyl acetate‐co‐vinyl neodecanoate), PVAc, stabilized with polyvinyl alcohol, PVOH.

Integrating Dimensional Personality and Autistic Traits to Predict Suicidal Ideation, Suicide Attempts, and Nonsuicidal Self‐Injury in Autistic Adults

Autism Research, EarlyView.
ABSTRACT Given the elevated rates of suicidal ideation, suicide attempts, and nonsuicidal self‐injury (NSSI) in autistic adults, we examined whether autism‐informed traits and transdiagnostic personality tendencies jointly relate to these outcomes.

Vocabulary of Autistic Preschool Children With Limited Language: Alignment With Early Word Inventories

Autism Research, EarlyView.
ABSTRACT There is a critical need to understand the early vocabulary of young children with autism who have limited language, defined in this study as producing fewer than 20 different spontaneous and functional spoken or augmented words, to better inform educational targets and vocabulary selection for spoken as well as augmentative and alternative ...

Reciprocal Associations Between Parental Anxiety/Depression and Emotional/Behavioral Difficulties in Autistic Children Following Their Diagnosis

Autism Research, EarlyView.
ABSTRACT Emotional and behavioral difficulties (EBD) are common in autistic children, while anxiety and depressive symptoms (ADS) are prevalent in their parents. However, the bidirectional relationship between the parents' and children's symptoms remains unclear, especially in the years following the child's autism diagnosis.

Resonance phenomena in the second differential order equations with nonlinear impulsive effects

Electronic Journal of Qualitative Theory of Differential Equations
In this paper, we discuss the resonance phenomena in linear and weakly nonlinear impulsive differential equations. Using a topological approach, we obtain the Landesman–Lazer type necessary and sufficient conditions for the existence of periodic ...
