Modelling the change in heat load with time is difficult for products with variable and complex geometries and compositions, such as beef carcasses. However, accurate heat load prediction is important for efficient design and operation of refrigeration systems. A simple method for constructing a model to predict the time-variable product heat load profile during chilling applications is propose...

A potential customer judges the aesthetic appeal of a product before the physical performance. This clearly indicates the importance of aesthetic shapes for the success of an industrial product. In curve design environment, a curve is characterized based on its curvature profile. A curvature profile is a graph plotted with the values of parameter t representing x-axis against its corresponding ...
