A new fixture for FSW processes of titanium alloys

2010

FSW of titanium alloys is nowadays one of the most challenging welding operations, even with a solid state process, due to the thermo-mechanical and thermo-chemical characteristics of such materials. Due to the relevant application of titanium alloys in the aeronautic and aerospace industries, in the recent years few attempts were carried out to develop FSW processes aimed to maximize the mechanical performances of the welded parts. In the paper a new fixture is presented allowing obtaining effective FSW joints of titanium blanks, which were investigated through mechanical and metallurgical tests highlighting the peculiarities of FSW of titanium alloys.

Fluid-structure interaction approach with smoothed particle hydrodynamics and particle-spring systems

2022

This paper presents a novel three-dimensional fluid-structure interaction (FSI) approach, where the meshless smoothed particle hydrodynamics (SPH) method is used to simulate the motion of incompressible fluid flows, whilst structures are represented by a simplified approach based on particle-spring systems. The proposed FSI technique allows to use independent spatial-temporal resolutions for the fluid and structural computational domains. The particle-spring elastic constants are calibrated and relationships with the mechanical material properties, Young's modulus and Poisson's ratio, are determined. Fluid and structure computational domains are separated by interfaces made of triangular el…

Biophysical investigation on therapeutic proteins (Chaperonins, Hsp60 and CCT/TRiC) involved in human diseases

Molecular chaperones are indispensable cellular components that assist folding and assembly of newly synthesized proteins, translocation of proteins across membranes, as well as refolding and degrading of misfolded and aggregated proteins. In the last few years, innovative therapeutic strategies targeting stability and functionality of chaperones have received great attention, particularly in the field of neurodegenerative diseases. Moreover, the growing number of diseases found linked to chaperone mutations, testifies to the importance of their role in the cellular protein-quality control mechanism. The investigation of the biophysical interactions between chaperones and specific proteins …

SAP FSM integrācija ar SAP ECC

2022

Tehnoloģiju videi un iespējām attīstoties, uzņēmumu informācijas sistēmu ainavas kļūst aizvien neviendabīgākas un sastāv gan no lokālām, gan mākonī bāzētam sistēmām, līdz ar to ir neizbēgami, ka integrāciju temats kļūst vēl jo vairāk aktuāls, lai nodrošinātu efektīvu un vienotu datu izmantošanu starp sistēmām gan efektivitātes, gan integritātes nolūkos. Zīmīgs piemērs iepriekš minētajai situācijai ir uzņēmumi, kuri saskaras ar nepieciešamību kopīgot datus starp SAP ECC (SAP ERP Central Component) un SAP FSM (SAP Field Service Management) sistēmām, kas ir šī darba temats. Darba mērķis ir izpētīt un aprakstīt integrāciju izstrādes iespējas starp abām sistēmām, izmantojot SAP Integration Suite…

Correlated Channel Model for terrestrial Free Space Optics and project specifications evaluation of LT code in OOK modulation

2011

Free Space Optics is a wireless line-of-sight communication system able to offer good bandwidth performance as well as straightforward installation and relocation. So that it represents a modern technology that allow to realize large bandwidth communication particularly when it is not possible to employ physical cable or radio technologies. Examples of FSO applications are: wireless backaul, fiber backup, temporary links, metro network extension and last mile access[1]. FSO is based on optical signals propagation in air and that is why it suffers of impairments which depend on atmospheric conditions. In detail, FSO suffers of scattering (i. e. Rayleigh and Mie) losses, absorption and scinti…
