What are natural concepts? A design perspective

Concepts Are Not a Natural Kind*

In cognitive psychology, concepts are those data structures that are stored in long-term memory and are used by default in human beings’ higher cognitive processes (categorization, inductive and deductive reasoning...). Most psychologists of concepts assume that these mental representations share many scientifically important properties, and the psychology of concepts is expected to describe th...

What are Stem Cells?

  Stem cells are undifferentiated self regenerating multi potential cells. There are three types of stem cells categories by the ability to form after cells and correlated with the body’s development process. Totipotent: these stem cells can form an entire organism such as fertilized egg. Ploripotent: ploripotent cells are those that can form any cell in the body but cannot form an entire organ...

What are Natural Kinds ?

1. Two Questions Distinguish two questions about natural kinds. First, the naturalness question: what, if anything, makes a natural kind natural? Perhaps the members of a natural kind, unlike the members of an arbitrary group, stand in some natural similarity relation to one another. Perhaps they share an essence or some other natural feature. Or perhaps, as conventionalists argue, the boundari...

Synthesis of Design Concepts from a Design for Assembly Perspective

Assembly is often a labor intensive and costly process. Techniques such as design for assembly, and automatic assembly planning have been reported in an attempt to lower the high cost of assembly. Automatic assembly planning is concerned with finding the optimal sequence of assembly for a given design. On the other hand, design for assembly (DFA) examines the given design to evaluate its “fitne...
