Nonlinear Dynamics of a Passive Walker: Bifurcation and Stability Insights With Spring and Damper Mechanics

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study explores the nonlinear dynamics associated with a passive dynamic walker (PDW), focusing on the bifurcation and stability insights derived from spring and damper mechanics. PDWs, which rely on gravity for stable locomotion without active control, exhibit a rich spectrum of behaviors, from periodic to chaotic motion.

Vibration Attenuation of Cantilever Beam Using Electromagnetic Delayed Feedback

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study presents a combined analytical and numerical investigation of a single‐input single‐output delayed feedback controller designed to suppress vibrations in a cantilever beam actuated by an electromagnet positioned beneath its free end. An analytical model was developed using the linearized equation of motion for a transversely excited

Reconsidering Volume‐Based Drug Procurement Policy: The Consequences of Manufacturers' Optimal Production Planning and Breach Strategies

Naval Research Logistics (NRL), EarlyView.
ABSTRACT This paper examines the impacts of Volume‐Based Procurement (VBP) policies on pharmaceutical supply chains, with a focus on the strategic behaviors of manufacturers. VBP aims to reduce costs and stabilize supplies by centralizing procurement through competition based on volumes and prices.

Tetrataenium paikadae (Apiaceae), a new species from the Western Ghats, India

Nordic Journal of Botany, EarlyView.
A new species, Tetrataenium paikadae C.Rekha, Manudev & Prasanth (Apiaceae), is described from the State of Kerala, India. The new species is characterised by its hirsute to hispid stems, broadly ovate or rounded leaflets, long petioles with hirsute leaf sheaths, tomentose rays, symmetric flowers, ovate‐lanceolate involucel bracteoles, and mericarp ...

Dicrananthera hedyotidea C. Presl. (Melastomataceae) in Maranhão state, Brazil: first record and ecological niche model of the species

Nordic Journal of Botany, EarlyView.
Dicrananthera C. Presl. is a monospecific genus of the tribe Marcetieae, comprising perennial herbs typically occurring in areas adjacent to wetlands. The species exhibits a disjunct distribution, with confirmed records in both the Amazon and Atlantic Forest domains.
