The evolution of software evolvability

Chris Lüer, David S. Rosenblum, André van der Hoek
2002 Proceedings of the 4th international workshop on Principles of software evolution - IWPSE '01  
We analyze two trends that have influenced the evolvability of component-based applications: increase of component exchangeability and increase of component distance.  ...  We discuss the various stages of evolvability in these dimensions, describe the state of the art, and speculate on future developments.  ...  We identify several stages in each of these trends, including past stages that are often considered as outdated, and stages that many consider to be state of the art, but that are not widely used yet.  ...

THE OCCURRENCE PROBABILITIES OF ROGUE WAVES IN DIFFERENT NONLINEAR STAGES

Aifeng Tao, Keren Qi, Jinhai Zheng, Ji Peng, Yuqing Wu
2014 Coastal Engineering Proceedings  
for wave fields with a broad range in frequencies.  ...  Based on the simulation, we find that the Kurtosis evolves distinctly at three nonlinear stages and shows a weak relation to the probabilities of the Rouge Waves.  ...  If a wave train can propagate in a large scale distance, or a sea state can evolve for a long time, such as the ocean in the monsoon seasons, the nonlinearity may grow to a stage beyond the Benjamin-Feir  ...

The pace of modern life II: From rates of contemporary microevolution to pattern and process [chapter]

Michael T. Kinnison, Andrew P. Hendry
2001 Microevolution Rate, Pattern, Process  
The magnitude of evolutionary difference increased with the length of the time interval, particularly when maximum rates from a given study were considered.  ...  We compiled a database of microevolution on contemporary time scales in nature (47 source articles; 30 animal species), comprising 2649 evolutionary rates in darwins (proportional change per million years  ...  A slowing rate of evolution with increasing time is a standard finding over macro-scales (Gingerich, 1983; Lynch, 1990 ) but has been challenged as a possible analytical artifact of log analyses and sampling  ...

Active Galaxies in the Sloan Digital Sky Survey II: galaxy and activity evolution [article]

Pietro M. Reviglio, David J. Helfand
2009 arXiv   pre-print
In agreement with such a hypothesis, we find that star-formation as traced by radio emission is progressively more centrally concentrated in more evolved star-forming galaxies and we show that the environment  ...  We demonstrate an evolution in the strength of the radio power and the spectroscopic emission-lines typical of AGN, as well as in the morphology of their hosts.  ...  increase in late type systems with decreasing large-scale environmental density.  ...

Cometary topography and phase darkening

J.-B. Vincent
2019 Astronomy and Astrophysics  
Meanwhile, ground based observers have published measurements of the phase functions of many JFCs and reported a trend in the phase darkening, with primitive objects showing a stronger darkening than evolved  ...  Many authors have investigated this evolution; Vincent et al. (2017) have used topographic data from all comets visited by spacecrafts to derive a quantitative model which relates large scale roughness  ...  We display the average results in Fig. 3 . As expected, the illuminated area is significantly reduced by increasing the large-scale roughness of the topography.  ...

Polarity reversals in geodynamo models with core evolution

Peter Driscoll, Peter Olson
2009 Earth and Planetary Science Letters  
In contrast, a dynamo started in a non-reversing state and subject to an increasing (anomalous) inner core growth rate and constant rotation evolves over 20 Myr to a reversing state with substantial trends  ...  Numerical dynamos with time-variable control parameters that simulate the secular evolution of the core are used to interpret long-term trends in geomagnetic field behavior, including polarity reversal  ...  The large trends in velocity and dipole field intensity in the anomalous evolution case A are clearly evident in Figs. 1 and 2 .  ...

A Numerical Investigation on Tidally Induced Sediment Transport and Morphological Changes with Changing Sea Level in South-East England

Nicoletta Leonardi, Xiaorong Li, Iacopo Carnacina
2019 Geosciences  
Our results suggest that the long term (century scale) tidally-induced morphological evolution of the seabed slows down in time and promotes a vanishing net transport across the large scale system.  ...  England as a test case.  ...  The funders had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript, or in the decision to publish the results.  ...

Evolution of force networks in dense granular matter close to jamming

Lou Kondic, Miroslav Kramár, Lenka Kovalčinová, Konstanin Mischaikow, F. Radjai, S. Nezamabadi, S. Luding, J.Y. Delenne
2017 EPJ Web of Conferences  
However, it is not immediately clear whether the force networks, defined on contact networks by considering force interactions between the particles, evolve on a similar time scale.  ...  To analyze the evolution of these networks, we carry out discrete element simulations of a system of soft frictional disks exposed to compression that leads to jamming.  ...  Since the evolution of force networks varies from realization to realization, and the distances between considered states of the system may be rather noisy, we considered the averages over a large number  ...

Haiyang Fang, Dali Jiang, Tinghong Yang, Ling Fang, Jian Yang, Wu Li, Jing Zhao, Constantine Dovrolis
2018 PLoS ONE  
This work proposes a new evolution model of supply chain with manufactures as the core, based on external market demand and internal competition-cooperation.  ...  The simulation results suggest that the networks evolved by our model have similar structures as real supply chains.  ...  Acknowledgments Thanks are due to Professor Willems for providing 38 datasets in his article, which make us enable to verify our proposed method.

As a consequence, it was a very wasteful process: in order to achieve a small improvement in any given adaptation, huge numbers of variant organisms were produced and failed.  ...  It is as if the evolution of life on any planet is a developmental process that has a very unusual characteristic: evolution will continue to develop successfully beyond a certain point only if it produces  ...  Volume III Number 3 2019 The Mounting Case in Favour of a Trajectory towards Increasing Integration and Cooperation An evident trend towards increasing integration Various versions of another large-scale  ...

2011 Ecography  
Recently, a grid-cell assemblage analysis found significant body size trends with latitude and temperature in Plethodon salamanders, and support for the heat-balance hypothesis as a possible explanation  ...  A major goal in macroecology is to determine how body size varies geographically, and explain why such patterns exist.  ...  This work was sponsored in part by NSF grant DEB-0446758 to DCA.  ...
