Traditional vs. Modern Approaches
Published on 2026-02-02 by Dejan Baji?, Eleonora Desnica, Mi?a ?ur?ev, Ivan Palinka, Luka ?or?evi? @MDPI
Abstract: This paper presents a comparative analysis of time parameters involved in the preparation phase of machining processes of the taper tap, contrasting traditional and modern approaches. The study examines the time required for the creation of a technological process sheet using traditional methods, and the time necessary for 3D modeling and CNC machine programming using modern CAD/CAM software Fusion 360 software (version v2.0.21286). Both approaches are based on the same workshop drawing so initi[...]
Our summary: This paper compares time parameters in the preparation phase of machining processes for taper taps using traditional and modern approaches. It analyzes time consumption for creating a technological process sheet manually versus using Fusion 360 software for 3D modeling and CNC programming. The study aims to identify which method offers higher practical efficiency in specific production contexts.

A Multi-Criteria Analysis Tool for Model Optimization
Published on 2026-01-26 by Andrzej Szymon Borkowski @MDPI
Abstract: This study addresses the challenge of identifying heavy Building Information Modeling (BIM) library components that disproportionately degrade model performance. While BIM has become standard in the construction industry, heavy components characterized by excessive geometric complexity, numerous instances, or inefficient optimization—cause extended file loading times, interface lag, and coordination difficulties, particularly in large cross-industry projects. Current identification[...]
Our summary: This study introduces a multi-criteria evaluation method for identifying heavy BIM components that degrade model performance. It quantifies component impact using five weighted criteria and implements the method as a pyRevit plugin called HeavyFamilies. Validation shows effective identification of heavy components, enabling proactive quality control in construction projects.

Total Ionizing Dose Effect Simulation Study on 130 nm CMOS Processor
Published on 2026-01-20 by Yi Liu, Yuchen Liu, Xinfang Liao, Changqing Xu, Yangchen He, Yintang Yang @MDPI
Abstract: This paper reports the results of a system-level total ionizing dose (TID) effect simulation study on a SMIC 130 nm LEON2 processor. Firstly, the device-level simulations of the 130 nm NMOS transistors are performed using the Sentaurus TCAD software to analyze the effects of a bias condition, channel width, and irradiation dose on a TID-induced leakage current. Based on the TCAD simulation results, a Verilog-A-based compact model is developed for NMOS transistors to describe the TID-induced leak[...]
Our summary: This study investigates the total ionizing dose (TID) effects on a 130 nm CMOS processor. Device-level simulations of NMOS transistors are conducted using Sentaurus TCAD to analyze leakage current under various conditions. A Verilog-A compact model is developed and integrated into SPICE for system-level TID simulations, revealing the processor s failure threshold and mechanisms.

Hierarchical and Robust Intelligent Design System for Aircraft Skin Die Face of Stretch Forming
Published on 2026-01-14 by Xilei Zhang, Haijiao Kong, Zhen Wang, Yang Wei, Yuqi Liu, Zhibing Zhang @MDPI
Abstract: Most aircraft skin components are typical sheet metal components, and stretch forming serves as the primary forming process. The die face is the core foundation for both the finite element simulation and mold trial. Due to the intricate geometric characteristics of aircraft skin components and iterative revisions caused by stretch forming process adjustments and product design changes, the die face design of aircraft skin components is inherently time-intensive, highly complex, and prone to inst[...]
Our summary: The proposed Hierarchical and Hybrid Association Method (HHAM) enhances die face design stability and efficiency for aircraft skin components. It employs a robust updating mechanism and integrates parametric modeling to address complexity and instability in the design process. Successful industrial applications demonstrate significant improvements in design efficiency and error reduction.
