RandomAccess test (previously called GUPS and guppie) measures a sustained rate (measured in GUPS) of updates to random locations in main memory. The random numbers may be generated by a variety of methods. In this paper two random generators are considered: one based on shift registers and one based on linear congruence relation. The quality of the main memory address distribution is considere...

The objective of this study is to compare the performance of different k-ε models, i.e. the Standard k-ε, the Renormalization Group (RNG) k-ε, and the Realizable k-ε, with a two-layer model for the prediction of the mean velocity field and the temperature pattern from a newly designed impinging jet supply device for ventilation of an office room. The numerical predictions are validated against ...

Power-to-gas is a promising option for storing interment renewables, nuclear baseload power, and distributed energy and it is a novel concept for the transition to increased renewable content of current fuels with an ultimate goal of transition to a sustainable low-carbon future energy system that interconnects power, transportation sectors and thermal energy demand all together. The aim of thi...

This paper describes the design of the random number generator (RNG) in the Caernarvon high assurance smart card operating system. Since it is used in the generation of cryptographic keys and other sensitive materials, the RNG has a number of stringent security requirements that the random bits must be of good quality i.e. the bits must not be predictable or biased. To this end, a number of sta...

We consider a wireless network composed of a set of n wireless nodes distributed in a two dimensional plane. The signal sent by every node can be received by all nodes within its transmission range, which is uniform and normalized to one unit. We present the first distributed method to construct a bounded degree planar connected structure LRNG, whose total link length is within a constant facto...

When subjects are required to generate a random sequence of numbers they typically produce too many forward and backward ‘counts’ (e.g. 5--6, 4--3). This counting bias is interpreted as the consequence of an interference by overlearned tendencies to arrange numbers according to their natural order. Inhibition of such welllearned routines is known to rely on frontal lobe functioning. We examined...

Studies of anomalous correlations between mind and matter usually focus on participating subjects and isolated target systems. We report on a decade-long experiment which finds that anomalous mind-matter correlations may be a pervasive aspect of reality. The Global Consciousness Project (GCP) measures the output deviation of a global network of physical random number generators (RNG) at the tim...

A family F = (F(i) \iel) is a function from an index set / into the set of all non-empty subsets of a set. A subset G e F is called a subfamily of F and a function / f rom / into u (F(/) \iel} such that / ( t ) e F(i) is called a choice function. Let F be a function. Dmn F denotes the domain of F and rng F denotes the range of JF. If F is a function and J £ dmn F, then F \ J will denote the res...

We present a simple and efficient distributed method for determining the transmission power assignment that maximises the lifetime of a data-gathering wireless sensor network with stationary nodes and static power assignments. Our algorithm determines the transmission power level inducing the maximum-lifetime spanning subgraph of a network by means of a distributed breadth-first search for minm...

Random and pseudorandom number generators (RNG and PRNG) are used for many purposes including cryptographic, modeling and simulation applications. For such applications a generated bit sequence should mimic true random, i.e., by definition, such a sequence could be interpreted as the result of the flips of a fair coin with sides that are labeled 0 and 1. It is known that the Shannon entropy of ...
