Spheres, tears, and spears: Regulating the perimeter and circularity of millimeter‐sized alginate hydrogel beads

open access: yesAIChE Journal, Volume 72, Issue 6, June 2026.
Abstract Generating hydrogel beads pertains to many engineering applications. We examined two alginate‐based fluids at three concentrations of alginate, cAG. We used the “Map of Misery” to determine which material property (viscosity, elasticity, and inertia) drives droplet formation. Next, we measured the perimeter and circularity of hydrogel beads as

Dynamic analysis of the generalized slider crank

open access: yes, 1991
A numerical technique is used to analyze the kinematics of the generalized slider crank mechanism and an analytical technique to derive dynamic force equations for that mechanism has been formulated. The numerical technique used for displacement analysis

Advanced control of non‐isothermal axial dispersion tubular reactors with recycle‐induced state delay

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 3018-3037, June 2026.
Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...

Position Tracking Of Slider Crank Mechanism Using Pid Controller Optimized By Ziegler Nichol’s Method

open access: yes, 2015
This paper presents a study on the position tracking response of a Propotional-Integral-Derivative (PID) controlled- slider crank mechanism, which is driven by a two phase stepper motor.

An Integrated Engine Control Unit for a Spark Ignited Internal Combustion Engine

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
This study proposes an FPGA‐based integrated engine control unit (IECU) that combines ECU and valve control functions. It introduces a piston‐direction sensor for synchronization, supports variable timing for key‐cylinder events, enables high‐resolution virtual crank‐angle timing, and implements adaptive rule‐based control to improve real‐time engine ...

Robust Control Using a Matrix Converter to Enhance Wind Turbine Systems

open access: yesEnergy Science &Engineering, Volume 14, Issue 6, Page 2785-2815, June 2026.
This study uses a more efficient and effective solution to improve the operational performance of a wind turbine‐based power system. This system uses a doubly fed induction generator and relies on a matrix converter and fractional‐order proportional–integral controller.

Shaping Function: Polymeric 3D Systems With Unconventional Geometries for Biomedical Applications

open access: yesSmall, Volume 22, Issue 33, 12 June 2026.
Particle shape is a key design parameter governing biological interactions. Advances in fabrication enable precise control over anisotropy and compartmentalization, allowing modulation of cellular uptake, transport, and biodistribution, ultimately enhancing therapeutic performance. ABSTRACT Polymer geometry is a primary determinant of physical behavior
