Modeling of a Variable-BVR Rotary Valve Free Piston Expander/Compressor [PDF]
, 2016 The concept of a free-piston expansion/compression unit with a variable Built-in Volume Ratio (BVR) is proposed. This device has no crankshaft mechanism which provides a possibility to optimize the expansion process free of mechanical limitations.

A Heavy‐Duty Vehicle Routing Problem With Temperature Constraints
Networks, Volume 87, Issue 2, Page 131-150, March 2026.ABSTRACT This article studies a vehicle routing problem involving a fleet of heavy‐duty vehicles and pickup‐and‐delivery requests for crude items that are both heavy and high‐temperature. The objective is to route the fleet in such a way that maximizes resource efficiency and operational efficiency while simultaneously avoiding thermal overload of any ...

Comparison of Four Space Propulsion Methods for Reducing Transfer Times of Manned Mars Mission
, 2015 We assess the possibility of reducing the travel time of a manned mission to Mars by examining four different propulsion methods, and keeping the mass at departure under 2,500 tonnes, for a fixed architecture. We evaluated representative systems of three

steel research international, Volume 97, Issue 3, Page 1201-1225, March 2026.This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Multipole Multi-Layered Magnetorheological Brake with Intermediate Slots
Applied SciencesMagnetorheological (MR) brakes are flourishing in low-torque applications due to their dynamic controllability nature. Researchers have introduced multi-layer and multipole concepts to increase the torque–volume ratio (TVR) of the MR brake.

Analytical results for rotating and linear magnetic brakes
Advanced Electromagnetics, 2018 A theory of magnetic damper (eddy-current brake) which can be applied to axial-flux rotating and linear systems moving under the influence of an arbitrary arrangement of magnetic poles is derived from basic electromagnetic principles.

Imposed expiratory resistance, dynamic hyperinflation and locomotor power and fatigue
Experimental Physiology, Volume 111, Issue 3, Page 809-819, 1 March 2026.Abstract Expiratory flow limitation results in dynamic hyperinflation, dyspnoea and premature exercise intolerance. We aimed to measure whether expiratory resistance reduces locomotor power via limiting maximal voluntary motor activity, exacerbating muscle fatigue, or both.
