The challenge in designing new three-dimensional (3D) shapes is that considerable manual effort required for repeated and verification to satisfy the specifications. Extracting standardizing parametric design rules from a designed 3D shape dataset will be useful drastically reducing time. This paper describes framework of automatically generating models, rules, order standardize designs structu...

A complete parametric approach is proposed for the design of the Luenberger type function Kx observers for descriptor linear systems. Based on a complete parametric solution to a class of generalized Sylvester matrix equations, parametric expressions for all the coefficient matrices of the observer are derived. The approach provides all the degrees of design freedom, which can be utilized to ac...

The act of design in landscape architecture consists a concept within designer’s mind, technical representations, and finally, process construction. In the 4th Industrial Revolution, is facing many changes due to rapid development computer technology IT ecosystem. Computer was initially developed for simple functions, such as mathematical calculation graphic representation. However, after sprea...

Computer-aided font design is still a very tedious and repetitive task. New font models and new functionalities presented by digital media further require a new method for design of font families and dynamic variable fonts. Current design paradigms are either outline based, offering low level operations, or parametric but non-visual programming. Parametric feature based design helps in creating...

Tubular KT-joints are quite common in offshore structural design and despite the crucial role of stress concentration factors (SCFs) in evaluating the fatigue performance of tubular joints. However, the SCF distribution in internally ring-stiffened KT-joints have not been investigated and no design equation is currently available to determine the SCFs for this type of joint. In the present pape...
