Balancing BlockRAM and distributed RAM

Xilinx FPGAs offer both Block SelectRAM and distributed RAM for embedded memory. To investigate the impact of utilizing such opportunities, some variations on the hardware implementation of a SNOW 2.0 stream cipher IP core have been designed. We find the ratio of throughput and effective slice usage to be close to 3.5. This allows a flexible trade-off between speed and area consumption, with a thr

Systematics, phylogeography and multiple origins of morphs in two species complexes belonging to Cistaceae, Helianthemum oelandicum and H. nummularium

Popular Abstract in Swedish Istiden har påverkat utbredning och variation hos många växter i Europa, framförallt arter i tempererade områden (dvs. norra Europa). Under den sista istiden (som slutade för mindre än 15 000 år sedan) täcktes stora delar av norra Europa, bl.a. hela Skandinavien och norra England, av ismassor. Bergskedjor som finns i södra Europa, t.ex. Karpaterna, Pyrenéerna och AlpernThe Helianthemum oelandicum complex shows considerable morphological variation across its geographic distribution in Europe and western Asia. By combining four primer pairs and four restriction enzymes I identified nine cpDNA haplotypes with distinct geographical distributions. Two haplotypes were most frequent over most of the range; one in western Europe and one in eastern Europe. Moreover, diff

Hedonism as the Explanation of Value

This thesis defends a hedonistic theory of value consisting of two main components. Part 1 offers a theory of pleasure. Pleasures are experiences distinguished by a distinct phenomenological quality. This quality is attitudinal in nature: it is the feeling of liking. The pleasure experience is also an object of this attitude: when feeling pleasure, we like what we feel, and part of how it feels is

A knowledge integration framework for robotics

This paper describes a knowledge integration framework for robotics, whose goal is to represent, store, adapt, and distribute knowledge across engineering platforms. The architecture abstracts the components as data sources, where data are available in the AutomationML data exchange format. AutomationML is an on-going standard initiative that aims at unifying data representation and APIs used by e

beta-Hydroxyasparagine in domains homologous to the epidermal growth factor precursor in vitamin K-dependent protein S

Vitamin K-dependent protein S is involved in the regulation of blood coagulation. It is a 75-kDa single chain protein with an NH2-terminal gamma-carboxyglutamic acid-containing domain followed by a thrombin-sensitive region and four domains arranged in tandem, each of which is homologous to the epidermal growth factor (EGF) precursor. The NH2-terminal EGF-like domain contains beta-hydroxyaspartic
