Communication Chains and Multitasking
Norman Makoto Su
Video in druga učna gradiva
Oznake:
Observations revealed that information workers interact in“chains” of interactions, switching organizational contexts and communication mediums. We investigate how communication chains affect workplace stress and discuss chains as alignmentwork.

Eigenmode of Decision-by-Majority Process on Complex Networks
Makoto Uchida
Video in druga učna gradiva
Oznake: science;complexity science
The nature of opinion formation dynamics in complex networks is investigated using eigenmode analysis. Opinion formation dynamics is modeled by a decision-by-majority process of spin-like variables located at vertices of complex networks. Hamiltonian of the system is defined, and estimated by the ei ...

Initial transient phase and stability of annular laser beam direct wire deposition
Matjaž Kotar, Makoto Fujishima, Gideon N. Levy, Edvard Govekar
Izvirni znanstveni članek
Oznake: additive manufacturing;lasers;wire;
In this paper the stability of the annular laser beam (ALB) direct wire-deposition process, which enables process symmetry and a well-defined ALB workpiece irradiation proportion (WIP) and related energy input onto the workpiece and the wire surface is considered. Various initial process phase strat ...

Advances in the understanding of the annular laser beam wire cladding process
Matjaž Kotar, Makoto Fujishima, Gideon N. Levy, Edvard Govekar
Izvirni znanstveni članek
Oznake: annular laser beam;laser wire cladding;nominal workpiece irradiation proportion;process stability;clad geometry;melt pool and workpiece temperature;
This paper experimentally studies the influence of conventional process parameters (laser beam power, P, workpiece, and wire feeding velocities), and the nominal workpiece irradiation proportion WIPN parameter, on ALB-WC process stability and generated clad geometry. The study was based on an extens ...

Annular laser beam cladding process feasibility study
Alexander Kuznetsov, Andrej Jeromen, Gideon Levy, Makoto Fujishima, Edvard Govekar
Objavljeni znanstveni prispevek na konferenci
Oznake: kolobarjasti laserski žarki;navarjanje prahu;procesni parametri;izkoristek prahu;annular laser beams;powder cladding;process parameters;powder catchment efficiency;
In the paper a novel annular "ring shaped" laser beam cladding head and related cladding process are presented. In the cladding head a laser beam is shaped into an annular ring and guided coaxially with the powder tube disposing the powder jet in the centre of the focused annular laser beam ring. An ...

Study of an annular laser beam based axially-fed powder cladding process
Edvard Govekar, Andrej Jeromen, Alexander Kuznetsov, Gideon N. Levy, Makoto Fujishima
Izvirni znanstveni članek
Oznake: additive manufacturing;lasers;powder;
An annular laser beam based powder cladding head, which enables an axial powder feeding and variation of the laser beam intensity distribution (LBID) on the workpiece surface is presented. The influence of typical LBIDs, including Ring, Tophat(-), Tophat(+), and Gaussian-like, on a cladding process ...

Powder particle–wall collision-based design of the discrete axial nozzle-exit shape in direct laser deposition
Andrej Jeromen, Ana Vidergar, Makoto Fujishima, Gideon N. Levy, Edvard Govekar
Izvirni znanstveni članek
Oznake: direct laser deposition;axial nozzle shapes;wall-collision-dominated flow;powder-stream distribution;powder-catchment efficiency;
To improve the efficiency of the direct laser deposition (DLD) of metal powders, a concentrated powder-stream distribution is required, which can be affected by the shape of the powder-delivery nozzle. In this study, a simplified, powder particle–wall collision-based 3D numerical model of the powder ...
