Transforming growth factor-β (TGF-β) functions to suppress tumorigenesis in normal mammary tissues and early-stage breast cancers and, paradoxically, acts promote the metastasis chemoresistance late-stage cancers, particularly triple-negative (TNBCs). Precisely how TGF-β acquires oncogenic characteristics remains unknown, as does role of endogenous mammalian target rapamycin (mTOR) inhibitor, Dep domain-containing mTOR-interacting protein (Deptor), coupling TNBC development metastatic...
Lightweight aeronautical structures and power generation such as wind turbines are fitted with protected external layers designed certified to withstand severe climatic events lightning strikes. During these events, high currents flow through the structural protection but likely induce effects deeper in supporting composite material could even reach or perforate pressurized tanks. In situ measurements hard achieve during current delivery due electromagnetic conditions, strike phenomenon on...
In the context of enhancing sustainability aerospace vehicles, structures must be designed to anticipate possibility disassembly. Mandatory certification in aeronautics and robustness satellites require maintain their integrity ensure safety during life, which can come into conflict with need for disassembling or demising. This is particularly case composite assembled though adhesive bonding. this paper, a controlled disassembly device substrates component keeping surface states after...
The French Ministry of Defence's procurement agency, the Direction Générale de l'Armement (DGA), is in charge assessing and testing armament systems order to equip armed forces prepare for future.DGA Aeronautical Systems, technical centre dedicated evaluate test aircraft, combines evaluation clear, among others, parachute systems.The historically based on experimental data so requires numerous flight tests which can prove expensive time consuming.In have a greater understanding dynamic...
The purpose of this work is to evaluate the use smoothed particle hydrodynamics (SPH) method within framework high speed cutting modelling. First, a 2D SPH based model carried out using LS-DYNA® software. developed proves its ability account for continuous and shear localised chip formation also correctly estimates forces, as illustrated in some orthogonal examples. Then, used order improve general understanding machining with worn tools. At last, hybrid milling allowing calculation 3D...
Single point incremental forming (SPIF) process is gaining popularity for rapid manufacturing of complex 3D shapes. The present study aimed at numerically predicting the failure using Gurson-Tvergaard-Needleman (GTN) model and further clarifying deformation mechanics in SPIF. Deformation SPIF are examined by simulating a straight groove test. Solid finite element (FE) models have been employed to investigate modes. GTN damage has successfully predicted limits It shown that failure,...
Composite corners are generally tested under four point-bending to identify Inter-Laminar Tensile Strength design values. Hereafter several lay-ups have been defined in order characterize very different damage evolution processes. Damage monitoring has performed with the help of Digital Image Correlation, Acoustic Emission and Fast Video Recorder. The processes leading final failures identified. A deterministic continuous composite material model is used investigate these phenomena....
One of the main drawbacks traditional drilling process is formation long chips when cutting metallic parts. Usually, peck cycles are used to break and evacuate through flutes drill. However, this solution increases operation time therefore decreases productivity. To solve problem, vibration assisted has been developed meet industrial needs in terms Forced vibrations impose a variation chip thickness order obtain its fragmentation. This recently optimal conditions have yet be determined...
This article revisits methods based on global descriptors to estimate the pose of a known object using monocular camera, in context space rendezvous between an autonomous spacecraft and noncooperative target. These by detection, i.e., they do not require any prior information about observed object, making them suitable for initial acquisition monitoring faults other on-board estimators. We consider here specifically that retrieve precomputed set invariants geometric moments. Three classes...
The current work is intended to give an overview of issues related the numerical simulation adhesive spreading for liquid semi-liquid adhesives. advantages and limitations are presented in order guide choice suitable approach depending on case under consideration. It shown that methods two categories, whether they grid-based or meshless. In first, movement matter directly dependent mesh size distribution. Contrariwise, meshfree methods, particles free move each carries its properties....
This paper proposes Thales Alenia Space vision-based navigation solution for close proximity operations in autonomous space rendezvous with non-cooperative targets. The proposed covers all the phases of navigation. First, a neural network robustly extracts target silhouette from complex background. Then, binary is used to retrieve initial relative pose using detection algorithm. We propose an innovative approach object's precomputed set invariants and geometric moments. observation extended...
We show that the behavior of T700/M21s and T800/M21s composite panels are affected by influence strain rates together with local shear crush punch or global flexural strengths structure. A deterministic continuous material model has been developed as a LS-DYNA user defined for unidirectional composites on basis Matzenmiller widely used woven composites. Initiation evolution up to saturation fracture implemented various coupled damage mechanisms including delamination. Quasi-static dynamic...
