A modeled Polynesian society is used to explain why, in Polynesia, growing stratification did not result in a devaluation of women's status, as most theorists would predict. The computer model used to explore this problem--called TongaSim--is a C++ program that attempts to emulate the basic social dynamics of Tonga, a Western Polynesian society. The program is capable of simulating the operatio...

A priori interconnect prediction and technology extrapolation are closely intertwined. Interconnect predictions are at the core of technology extrapolation models of achievable system power, area density and speed. Technology extrapolation, in turn, informs a priori interconnect prediction via models of interconnect technology and interconnect optimizations. In this paper, we address the linkag...

This paper introduces our experience on development of a Grid Portal, which provides a weather forecast service via web browsers to its users. The development consists of two parts, as “Gridification” of a forecasting program with Ninf-G and its “Portalization” with GridLib. We could accomplish those work with a little deal of trouble. Especially, any modification to the program is not necessar...

In this paper, we propose a novel technique for the efficient prediction of multiple continuous target variables from high-dimensional and heterogeneous data sets using a hierarchical clustering approach. The proposed approach consists of three phases applied recursively: partitioning, localization and prediction. In the partitioning step, similar target variables are grouped together by a clus...

Although an increasing number of studies in mammals provide support to the Trivers-Willard prediction, evidence of this phenomenon in human remains controversial. Here, assuming that contemporary humans respond in an ancestral manner to recent improvements of lifestyle, we explored the hypothesis of a facultative adjustment of sex ratio in relation to resource availability from more than 120 co...

In recent years, much attention has been given to domain decomposition methods for solving linear elliptic problems that are based on a partitioning of the domain of the physical problem. More recently, a new class of Schwarz methods known as optimized Schwarz methods was introduced to improve the performance of the classical Schwarz methods. In this paper, we investigate the performance of thi...

Yarbus' pioneering work in eye tracking has been influential to methodology and in demonstrating the apparent importance of task in eliciting different fixation patterns. There has been renewed interest in Yarbus' assertions on the importance of task in recent years, driven in part by a greater capability to apply quantitative methods to fixation data analysis. A number of recent research effor...

We would like to thank Referee 2 for the suggestions and comments for improving the manuscript. In particular, we are grateful for pointing out the fact that the asymmetric delay components of the SD model counterparts do not follow a Gaussian distribution. Discussion on this issue is included in the revised manuscript, even though no definitive explanations can be provided at this stage. Our a...

We show how mixed finite element methods that satisfy the conditions of finite element exterior calculus can be used for the horizontal discretisation of dynamical cores for numerical weather prediction on pseudo-uniform grids. This family of mixed finite element methods can be thought of in the numerical weather prediction context as a generalisation of the popular polygonal C-grid finite diff...

Numerical Weather Prediction (NWP) and climate simulations have been intimately connected with progress in supercomputing since the first numerical forecast wasmade about 65 years ago. The biggest challenge to state-of-the-art computational NWP arises today from its own software productivity shortfall. The application software at the heart of most NWP services is ill-equipped to efficiently ada...
