The heavy elements formed by neutron capture processes have an interesting history from which we can extract useful clues to and constraints upon the star formation and nucleosynthesis history of Galactic matter. Of particular interest are the heavy element compositions of extremely metal-deficient stars. At metallicities [Fe/H] ≤ -2.5, stellar abundance data (for both halo field stars and glob...

The paper presents a new methodology for conflict-based process synthesis. The objective is to handle the multi objective requirements and combinatorial nature of process synthesis from the point of view of the creativity-based approach to the problem solving. The development of the methodology deals with two main questions: how to define and identify the conflicts encountered in the design pro...

Assurance BasedDevelopment (ABD) is a novel approach to the synergistic construction of critical soware systems and their assurance arguments. InABD, theneed for assurance drives a unique process synthesis mechanism that results in a detailed process for building both soware and an argument demonstrating its fitness for use in given operating contexts. In this paper, we introduce the ABD proc...

Dynamic Texture Stimulation Model: Motion Clouds We first provide an axiomatic derivation of the Motion Clouds model introduced in [1]. In particular, we show that the original definition as a spatiotemporal stationary Gaussian field could be approximated by the random aggregation of warped patterns providing a generative model. We define a dynamic texture as 1 I (x, t) = p X p✓p (x Xp Vpt)) (1...

The traditional approach to model (business) processes as stepwise executable activities which interact with multiple partner processes by typed interfaces seems to lead to centralization or at least to a very tight coupling of the interacting systems. Here, a unifying approach is presented that models the specifications of both, deterministic processes as well as their possibly nondeterministi...

In this paper, we discuss what is knowledge for synthesis and how knowledge is used in synthesis process. Variety of knowledge is crucial in synthesis process like design. Such variety of knowledge in turn makes it difficult to collect and integrate knowledge that is the main process of synthesis. We model synthesis process as integration of knowledge units called design experiences that is des...

Power is widely considered the only real limiter for Moore’s Law in the next decade [Gelsinger, 2004]. Indeed, IBM CTO B. Meyerson has claimed that CMOS process scaling has already stopped between 130nm and 90nm due to power limitations [Clarke, 2004]. Existing methods for physical synthesis, however, have primarily targeted timing closure and are inadequate to meet the challenge of low-power p...

Monodispersed FePt nanoparticles are synthesized by reduction of iron(II) acetylacetonate and platinum(II) acetylacetonate with 1,2-hexadecanediol as the reducing reagent in the polyol process. As-prepared FePt nanoparticles are chemically disordered with fcc phase. Transmission electron microscopy (TEM) images show a self-assembled particle array with an average particle size of 3 nm and a sta...

Based on a wavelet-type expansion of the Rosenblatt process, we introduce and examine two different practical ways to simulate the Rosenblatt process. The synthesis procedures proposed here are obtained by either truncating the series of the approximation term or using the approximation coefficients in the wavelet-type expansion of the Rosenblatt process. Both benefit from the low computational...
