UAV‐Based Precision Seed Dropping for Automated Reforestation

Journal of Field Robotics, EarlyView.
ABSTRACT Wildfires and deforestation pose significant threats to forest ecosystems, motivating scalable methods for reforestation beyond labor‐intensive cultivation of native forest seedlings in nurseries. To enable large‐scale direct seeding of native species, this paper presents the design, analysis, and field evaluation of a UAV‐based seed‐dropping ...

Stabilizing Unstable Periodic Orbits of the Multi-Scroll Chua's Attractor

Nonlinear Analysis, 2007
This paper addresses the control of the n-scroll Chua’s circuit. It will be shown how chaotic systems with multiple unstable periodic orbits (UPOs) detected in the Poincar´e section can be stabilized as well as taking the system dynamics from one UPO to ...

The social life of money for children

The British Journal of Sociology, EarlyView.
Abstract Inspired by Nigel Dodd's The Social Life of Money, this article proposes an analysis of entangled economic lives, that is, how meaning, structures and politics jointly shape the flow of monies within households. The past decades have marked a shift from “childrearing expenditures” to “parenting investments” that align with new visions of both ...

Structured decision‐making as a framework to incorporate social equity into conservation decisions

Conservation Biology, EarlyView.
Abstract Many conservation challenges require negotiating trade‐offs between the needs of different actors. Global frameworks such as the Kunming–Montreal Global Biodiversity Framework explicitly call for diverse participation and social equity in conservation decision‐making.

Multiple Access Chua Chaotic Communication system using Real Orthogonal Matrix Approach [PDF]

Engineering and Technology Journal, 2018
An alternative to traditional Pseudo-Noise (PN)-Sequences, one-dimension (1D) orthogonal chaotic map sequences, and three dimensional (3D) continuous chaotic systems (x,y,z) are generated by orthonormal Gram-Schmidt process. A new Orthogonal Chua Chaotic

Which Decolonization? Theorizing Decolonization beyond Decoloniality and its Critics

Development and Change, EarlyView.
ABSTRACT The debate on decolonial thought has reached an unhelpful stalemate. A core problem in assessing decolonial thought is that the term ‘decolonization’ has been stretched so widely that it now allows for many competing uses. For some critics of decolonial thought such as Nigerian philosopher Olúfẹ́mi Táíwò, this overuse points to conceptual ...

Coexistence of Multiple Attractors in an Active Diode Pair Based Chua’s Circuit

, 2018
This paper focuses on the coexistence of multiple attractors in an active diode pair based Chua’s circuit with smooth nonlinearity. With dimensionless equations, dynamical properties, including boundness of system orbits and stability distributions of ...

Exponential stability of an alternate control system with double impulses

Journal of Inequalities and Applications, 2022
In this paper, we propose a new system called an alternate control system with double impulses. The present system is a cyclic control system, composed of four parts in a circle: to the first and last halves of each period of the system we add different ...

Expert consensus on oral management in autoimmune bullous diseases, erythema multiforme and SJS/TEN

Journal of the European Academy of Dermatology and Venereology, EarlyView.
This international Delphi study achieved expert consensus on 58 statements guiding the management of oral involvement in autoimmune bullous diseases, erythema multiforme and SJS‐TEN. The recommendations emphasize multidisciplinary care, oral hygiene and tailored topical, systemic and inpatient oral management.

Designing Chua’s circuit from the behavioral to the transistor level of abstraction [PDF]

, 2007
A MATLAB program is presented to design Chua’s circuit by applying state-variables at the behavioral level of abstraction. The user can interact with the program to calculate state trajectories by modifying the values of five circuit-elements: a resistor,
