A dilemma for cloud application users: scale up or scale out? . Purpose:. The purpose of this chapter is to introduce you to the Homogeneous Transformation. This simple 4 x 4 transformation is used in the geometry engines of CAD systems and in the kinematics model in robot controllers. It is very useful for examining rigid-body position and orientation (pose) of a sequence of robotic links and joint frames.. Nucleation of Ice. Suspect presence of foreign particle may aid nucleation of ice by allowing ice to form at higher temperatures compared to homogeneous nucleation of freezing –and at lower . humidities.

If frozen correctly, foods will keep most of their nutrients, color, texture and flavor. Hints for freezing. Cool ingredients. Fundamental question: . How (why?) do cloud droplets form in the atmosphere?. Water vapor can supersaturate as “closed” air parcels rise and cool (or cool some other way, e.g. . radiatively. ). Will drops form as soon as relative humidity exceeds 100%?. Wenting . Wang. Le Xu. Indranil Gupta. Department of Computer Science, University of Illinois, Urbana Champaign . 1. Scale up VS.
