In the previous three decades, many Radiation-Hardened-by-Design (RHBD) Flip-Flops (FFs) have been designed and improved to be immune to Single Event Upsets (SEUs). Their specifications are enhanced regarding soft error tolerance, area overhead, power consumption, and delay. In this review, previously presented RHBD FFs are classified into three categories with an overview of each category. Six well-known RHBD FFs architectures are simulated using a 180 nm CMOS process to show a fair comparison between them while the conventional Transmission Gate Flip-Flop (TGFF) is used as a reference design for this comparison. The results of the comparison are analyzed to give some important highlights about each design.

This paper presents the trilogy of virtual classifications, the speculative environment, the virtual inhabitant and the virtual built-form. These combine, generating a new realm of design within immersive architectural space, all to be designed relative to each other, this paper focuses on the speculative environment portion. This challenged computational design and representation through atmospheric filters, visible environment boundaries, materiality and audio experience. The speculative environment was generated manipulating the physical laws of the physical world, applied within the virtual space. The outcome provided a new spatial experience of architectural dynamics enhanced by detailed spatial qualities. Design concepts within this paper suggest at what immersive virtual reality can evolve into. Following an interconnective design methodology framework allowed a high level of complexity and richness to shine through the research case study throughout the process and final dissemination stages.
