Topology Optimization With a Local‐Like Global Stress Constraint Using a Fully Differentiable Aggregation Function

International Journal for Numerical Methods in Engineering, Volume 127, Issue 19, 15 October 2026.
ABSTRACT Over the last few decades, topology optimization (TO) has been developed into a valuable optimization method in many engineering fields. In structural optimization, limiting maximum mechanical stress is critical to the design of safe and reliable structures, a constraint that can be handled using TO.

Using Transactional Memory to Avoid Blocking in OpenMP Synchronization Directives

, 2015
OpenMP applications with abundant parallelism are often characterized by their high-performance. Unfortunately, OpenMP applications with a lot of synchronization or serialization-points perform poorly because of blocking, i.e.

Evaluating the Energy Efficiency of Optimization Techniques in C, Python, and Java

Software: Practice and Experience, Volume 56, Issue 10, Page 1221-1250, October 2026.
ABSTRACT Background Software plays a critical role in modern society, but its energy consumption is a growing concern. This issue is especially evident in the Internet of Things (IoT), which involves billions of devices operating under strict energy constraints, most of which rely on C Programming Language (PL) because of its energy efficiency.

An Architecture for a Tri-Programming Model-Based Parallel Hybrid Testing Tool

Applied Sciences, 2023
As the development of high-performance computing (HPC) is growing, exascale computing is on the horizon. Therefore, it is imperative to develop parallel systems, such as graphics processing units (GPUs) and programming models, that can effectively ...

Characterizing task-based OpenMP programs. [PDF]

PLoS ONE, 2015
Programmers struggle to understand performance of task-based OpenMP programs since profiling tools only report thread-based performance. Performance tuning also requires task-based performance in order to balance per-task memory hierarchy utilization ...

Concurrent Multi‐Scale Simulation of Progressive Damage in Laminated Composites Using Shell Finite Elements

International Journal for Numerical Methods in Engineering, Volume 127, Issue 16, 30 August 2026.
ABSTRACT This paper presents a study on multi‐scale modelling of progressive damage model in laminated composites using shell finite elements, with considerations for the effects of manufacturing defects. The approach utilises second‐order homogenisation with 5‐parameter shell formulation to capture the effects of complex sub‐structural geometry and ...

Spectrally Selective Bipolar Self‐Powered Opto‐Synaptic Responses in Tandem 2D van Der Waals Ferroelectric Heterojunctions

Advanced Functional Materials, Volume 36, Issue 62, 3 August 2026.
Tandem 2D vdW ferroelectric heterojunctions enable spectrally selective, self‐powered bipolar opto‐synaptic responses for retinal ON/OFF bipolar cell emulation and wavelength‐programmable logic operations. This work establishes vdW ferroelectric heterojunctions as a compelling materials platform for energy‐efficient, adaptive, and human‐like artificial
