Financial planning and decision making for the general public continues to vex and perplex in equal measure. Whilst the tools presented by a typical desktop computer should make the task easier, the recent financial crisis confirms the increasing difficulty that people have in calculating the benefits of deferring consumption for future gains (i.e. Saving). We present an interactive concept dem...

Sufficient conditions are proved for the existence of a A>factor or a Hamiltonian circuit in a graph G. The main element of each condition is a statement to the effect that \N(X)\ > a\X\ + b\V(G)\ + c for every non-empty independent subset X of V(G). The theorems are shown to contain various known results. 1. The theorems Neighbourhood conditions in graphs have been much studied [1, 2, 4, 6, 10...

It has been shown (1) in the dog that the development of a large negative intrathoracic pressure is associated with a marked fall in superior vena caval pressure and a slight fall in jugular venous pressure, while the development of a large positive intrathoracic pressure is associated with a rise in peripheral venous and superior vena caval pressure. In a recent, paper (2) it was shown that wh...

Recent research has shown that distinct physical regions in 3 the Venusian induced magnetosphere are recognizable from the variations 4 of strength of the magnetic field and its wave/fluctuation activity. In this pa-5 per the statistical properties of magnetic fluctuations are investigated in the 6 Venusian magnetosheath and wake regions. The main goal is to identify the 7 characteristic scalin...

Developing autonomous mobile robot system has been a hot topic in AI area. With recent advances in technology, autonomous robots are attracting more and more attention worldwide, and there are a lot of ongoing research and development activities in both industry and academia. In complex ground environment, obstacles positions are uncertain. Path finding for robots in such environment is very ho...

Why is spatial tuning in auditory cortex weak, even though location is important to object recognition in natural settings? This question continues to vex neuroscientists focused on linking physiological results to auditory perception. Here we show that the spatial locations of simultaneous, competing sound sources dramatically influence how well neural spike trains recorded from the zebra finc...

Hard spheres are a central and important model reference system for both homogeneous and inhomogeneous fluid systems. In this paper we present new high-precision molecular-dynamics computer simulations for a hard sphere fluid at a planar hard wall. For this system we present benchmark data for the density profile ρ(z) at various bulk densities, the wall surface free energy γ, the excess adsorpt...
