Modularity and hierarchy are fundamental notions in structured system design. By subdividing a large and unstructured problem into smaller and tractable chunks, design automation becomes possible. In this paper we discuss the use of modularity and hierarchy for functional specialization during the development of neural networks. We study the behavioral differences and requirements for back-propaga
Many universities have experienced an increase in the intake of students and at the same time cuts in the budgets for teaching. Many teachers have experienced that, for a number of reasons, they have to adjust their teaching or a course with short notice. These facts pose a challenge to the teachers’ agility in adapting to changes – and in doing it in a cost efficient way. We propose eXtreme Teac

Accumulation of acetate tends to reduce growth and recombinant protein production in E. coli cultivations. Formation of acetate can be avoided by a proper substrate feeding strategy, but most strategies require considerable process knowledge to work well. A feedback strategy is presented that requires minimal a priori information. The key idea is to exploit a characteristic change in the cell meta
Objective: Uninterrupted sleep is of vital importance for restoration and regaining health. In intensive care units (ICUs) where recovering and healing is crucial, patients' sleep often is fragmented and disturbed due to noise from activities from oneself, other patients, and alarms. The aim of our study was to explore if sleep could be improved by modifying the sound environment in a way that is
The FFT processor is one of the key components in the implementation of wideband OFDM systems. Architectures with a structured pipeline have been used to meet the fast, real-time processing demand and low-power consumption requirement in a mobile environment. Architectures based on new forms of FFT, the radix-2i algorithm derived by cascade decomposition, is proposed. By exploiting the spatial reg
Ultra-low power (ULP) biomedical implants and sensor nodes typically require small memories of a few kb, while previous work on reliable subthreshold (sub-VT) memories targets several hundreds of kb. Standard-cell based memories (SCMs) are a straightforward approach to realize robust sub- VT storage arrays and fill the gap of missing sub-VT memory compilers. This paper presents an ultra-low-leakag
