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

Drawing on a game‐theoretical background, this article seeks to develop an analytical framework for explaining the problems an international lawmaker is faced with when crafting norms on the sharing of protective burdens in the asylum field, and to apply this framework to selected problems of burden‐sharing in EU asylum and migration policies. It focuses on the category of risk and casts burden‐sh

This project is designed as a typical consultancy work for Environmental Engineering students at the Faculty of Engineering (LTH), Lund University, Sweden. It gives students a feeling of a possible future work by being a practical training in solving a complex environmental problem involving hydrological and ecological challenges. Additionally, the project work provides training of critical thinki
