Hybrid Auxetic Architectures: Integrating Curvature‐Driven Design for Enhanced Mechanical Tunability and Structural Performance

Advanced Engineering Materials, EarlyView.
Curvature‐tuned auxetic lattices are designed, fabricated, and mechanically characterized to reveal how geometric curvature governs stretchability, stress redistribution, and Poisson's ratio evolution. Photoelastic experiments visualize stress pathways, while hyperelastic simulations quantify deformation mechanics.

SNDR sensitivity analysis for cascaded ΣΔ modulators [PDF]

, 2000
Cascade, single and multi-bit, ΣΔ architectures provide stable, high order quantization noise shaping used in high resolution A/D conversion. One major disadvantage of cascaded ΣΔ topologies is the extreme SNDR sensitivity to gain mismatch between the ...

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Overview of the digital-to-analog converter module based on the MCP4725 chip and the digital-to-analog converter module based on the integrating RC circuit

Известия Томского политехнического университета: Промышленная кибернетика
In technical cybernetic systems, it is impossible to do without exchanging information between devices. Most modern control devices are digital, but it is not uncommon for an analog signal to be required to control executive devices, which can be changed

From Theory to Practice: Sub-Nyquist Sampling of Sparse Wideband Analog Signals [PDF]

, 2009
Conventional sub-Nyquist sampling methods for analog signals exploit prior information about the spectral support. In this paper, we consider the challenging problem of blind sub-Nyquist sampling of multiband signals, whose unknown frequency support ...
