This paper discusses the numerical simulations of heat transfer problem, particularly during welding materials processing. process highly depends on temperature to determine metallurgical properties, strength, and sureness joint welding; hence it is desirable study its flow. Finite difference method (FDM) used discretize partial differential equations (PDEs) obtain systems linear (SLEs), which ...

The Fuzzy Delphi Method (FDM) is one of the research methods used in obtaining experts’ consensus on specific issues. FDM a combination method and fuzzy theories. Although there are benefits using FDM, but literature review its application domain Human-Computer Interaction (HCI) still insufficient. Thus, this paper provided including HCI domain. This begins with presenting background methods, d...

BACKGROUND Current bone anchored hearing solutions (BAHSs) have incorporated automatic adaptive multichannel directional microphones (DMs). Previous fixed single-channel hypercardioid DMs in BAHSs have provided benefit in a diffuse listening environment, but little data are available on the performance of adaptive multichannel DMs in BAHSs for persons with unilateral sensorineural hearing loss ...

Fused deposition modelling (FDM) has so far been recognized for its reliability and simplicity manufacturing of geometrically-complex polymeric materials with 3D printing technique. Recently, the studies concerning properties fabricated by using FDM have growing, including those related to their wear resistance which is considered critical when a 3D-printed material must work sliding over surfa...

We model the 21cm power spectrum across Cosmic Dawn and Epoch of Reionization (EoR) in fuzzy dark matter (FDM) cosmologies. The suppression small mass halos FDM models leads to a delay onset redshift these epochs relative cold (CDM) scenarios. This strongly impacts its evolution. at given stage EoR/Cosmic process is also modified: general, amplitude fluctuations boosted by enhanced bias factor ...

Often, simple questions do not have obvious answers and require an experiment that yields unexpected answer. Have you ever wondered what will happen if turn 180 degrees to the commonly accepted FDM printing convention? The paper presents verification of possibility using reverse orientation print head in traditionally used 3D printers FFF/FDM systems. It has been shown mechanical parameters pri...

A 3D-printed microfluidic device was designed and manufactured using a low cost ($2000) consumer grade fusion deposition modelling (FDM) 3D printer. FDM printers are not typically used, or are capable, of producing the fine detailed structures required for microfluidic fabrication. However, in this work, the optical transparency of the device was improved through manufacture optimisation to suc...

Paper presents knowledge about types of test in area of materials properties of selected methods of rapid prototyping technologies. In today used rapid prototyping technologies for production of models and final parts are used materials in initial state as solid, liquid or powder material structure. In solid state are used various forms such as pellets, wire or laminates. Basic range materials ...
