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
Report on the deserted medieval chapel of Kabusa in Scania, Sweden. The report is part of a never fullfiled plan of publishing short building archaeological reports on all the medieval churches of the two counties Ljunits and Herrestad at Ystad in Scania as part. The investigation was conducted as a part of the research project "The Cultural Landscape during 6000 years in Southern Sweden", also ca
An analytical stiffness and eigenfrequency model of symmetric parallel 6-6 Stewart platforms (hexapods) is developed based on geometrical design variables to optimize the dynamical performance. The model is based upon Lagrangean dynamics in which the Bryant angles are used for the kinematics formulation. With the analytical eigenfrequency model, optimum stiffness characteristics can be obtained fo
