Curved Layer Fused Deposition Modeling

Current Fused Deposition Modeling (FDM) technologies deposit material as flat layers. The result is a “stair-case” effect on non-vertical or horizontal surfaces, and compromised part strength because of weakness between the laminations. This paper describes a FDM method through which layers of build material are deposited as curved layers following the shape of the part, thus removing the stair...

modeling insurance company expenses : the case study of iranian insurance industry

صنعت بیمه به دلیل عرضه محصول منحصر بفرد، در طبقه بندی مالی به عنوان یک صنعت با هزینه های بالا شناخته شده است. رفتار هزینه ها یک معیار مهم برای برای تعیین قدرت مالی شرکت بیمه استو این موضوع به ویژه برای بیمه گذاران و سرمایه گذاران از اهمیت اساسی برخوردار است. این مطالعه هزینه های شرکت های بیمه را در قالب سریهای زمانی پنلی انجام میدهد. تحلیل پنلی کمک برای درک رفتار نا متعارف، پیش بینی هزینه ها، و...

scour modeling piles of kambuzia industrial city bridge using hec-ras and artificial neural network

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

Modeling of Heat Flow and Solidification during Spray Deposition Process

The solidification behavior of droplets as well as spray-deposit of Al-4.5 wt% Cu alloy is simulated by modeling based on heat flow analysis. The model incorporates droplet dynamics and their thermal states during atomization process. The resultant spray enthalpy is used to analyze heat flow during solidification of the spray deposit. The effect of process variables like atomization pressure, m...
