The Historical Evidence For The Pessimistic Induction

Journal of dairy science, 2006

Dairy cattle breeding organizations tend to sell semen to breeders operating in different environments and genotype x environment interaction may play a role. The objective of this study was to investigate optimization of dairy cattle breeding programs for 2 environments with genotype x environment interaction. Breeding strategies differed in 1) including 1 or 2 environments in the breeding goal, 2) running either 1 or 2 breeding programs, and 3) progeny testing bulls in 1 or 2 environments. Breeding strategies were evaluated on average genetic gain of both environments, which was predicted by using a pseudo-BLUP selection index model. When both environments were equally important and the genetic correlation was higher than 0.61, the highest average genetic gain was achieved with a single breeding program with progeny-testing all bulls in both environments. When the genetic correlation was lower than 0.61, it was optimal to have 2 environment-specific breeding programs progeny-testi...

We now live in a world where architecture is produced through arrays of pixels and this remains as the representation rather than the reality of buildings inevitably ageing their physical forms. So if architecture is kept in this digitally frozen state, then how does architectural form age over time? It glitches. A glitch is defined as a sudden malfunction or fault caused by the harsh reality of digital decay. Currently glitches as a result of digital decay are solely explored as forms of 2d art therefore this thesis looks to reconnect the underlying data to its digital architectural spatial form and interpret digital decay in 3d. Our methodology follows a systematic iterative process of transformational change to explore design emergence on the base of computational glitches. A numerical data driven process is explored using decayed files which are turned into 3d formal expressions. In this context, stereoscopic techniques are experimented, helping understand further how glitch can be performed within a 3d virtual environment. Ultimately we explore digital architectural form existing solely in the digital realm that confidently expresses glitch in both its design process and aesthetic outcome. This thesis does not aim to answer the research question through a resolved building, we instead define architecture as three dimensional digital form and space. This thesis uses glitch as a methodology to design three dimensional spaces within the digital realm. The architecture exists in the digital therefore the spatial perception of architecture created through this research is in the eye of the beholder and their previous spatial experiences. Employing a methodology of transformational change to explore design emergence on the base of glitches or decayed files, the aim is to generate a contemporary architectural interpretation of decayed data.

This paper presents single-chip FPGA Rijndael algorithm implementations of the Advanced Encryption Standard (AES) algorithm, Rijndael. In particular, the designs utilise look-up tables to implement the entire Rijndael Round function. A comparison is provided between these designs and similar existing implementations. Hardware implementations of encryption algorithms prove much faster than equivalent software implementations and since there is a need to perform encryption on data in real time, speed is very important. In particular, Field Programmable Gate Arrays (FPGAs) are well suited to encryption implementations due to their flexibility and an architecture, which can be exploited to accommodate typical encryption transformations. In this paper, a Look-Up Table (LUT) methodology is introduced where complex and slow operations are replaced by simple LUTs. A LUT-based fully pipelined Rijndael implementation is described which has a pre-placement performance of 12 Gbits/sec, which is a factor 1.2 times faster than an alternative design in which look-up tables are utilised to implement only one of the Round function transformations, and 6 times faster than other previous single-chip implementations. Iterative Rijndael implementations based on the Look-Up-Table design approach are also discussed and prove faster than typical iterative implementations.
