Strange Grooves

determination of some physical and mechanical properties red bean

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...

Flow through the Grooves of Journal Bearings

A simple analysis of fully-developed Stokes ow in grooved bearings is performed that does not use lubrication scaling arguments as in Muijderman (1966). When the inertial terms are ignored, the Navier{Stokes equations decouple. The ow through the groove is then determined from a Poisson equation for the only component of velocity that contributes to the ow through the bearing. This velocity is ...

Influence of Rolling on Microstructure and Mechanical Properties of Bronze-Steel Explosive Welded Sheets

In this paper, the microstructure and mechanical properties of the plain carbon steel-bronze interface of explosive welding and rolling were investigated. Explosive connection was done at two stop distances and with two different thicknesses of explosive material. Rolling of the welded composite was done at both ambient and preheated temperatures of 300 °C and with a constant thickness reductio...

Real Time Scratches and Grooves

We present a GPU-accelerated algorithm to render surface detail features like scratches and grooves in real time. Our method efficiently models these features using a continuous representation that is stored in two textures. The first texture plays the role of a hash and provides pointers to the second texture containing the scratches paths, profiles and material information. This data is evalu...
