Selected Papers of the 3rd European Conference on Artificial Evolution (AE97). Vol 1363. Nimes, France: Springer-Verlag; 1998: 303-313.In this paper, we present the implementation, both in a simulator
and in a real-robot version, of an efficient solution to the so-called
dynamical nightwatch’s problem on the micro-robot Khepera. The problem
consists mainly in exploring a previously unknown environment while
detecting, registering and recognizing light sources which may dynamically
be turned on and off. At the end of each round a report is requested
from the robot. Therein we made use of an agent-based approach and
applied a self-organizing feature map in order to refine some of the behaviour
generating control-modules

Reciprocity in predator-prey interactions: Exposure to defended prey and predation risk affects intermediate predator life history and morphology
No full textA vast body of literature exists documenting the morphological, behavioural and life history changes that predators induce in prey. However, little attention has been paid to how these induced changes feed back and affect the predators' life history and morphology. Larvae of the phantom midge Chaoborus flavicans are intermediate predators in a food web with Daphnia pulex as the basal resource and planktivorous fish as the top predator. C. flavicans prey on D. pulex and are themselves prey for fish; as D. pulex induce morphological defences in the presence of C. flavicans this is an ideal system in which to evaluate the effects of defended prey and top predators on an intermediate consumer. We assessed the impact on C. flavicans life history and morphology of foraging on defended prey while also being exposed to the non-lethal presence of a top fish predator. We tested the basic hypothesis that the effects of defended prey will depend on the presence or absence of top predator predation risk. Feeding rate was significantly reduced and time to pupation was significantly increased by defended morph prey. Gut size, development time, fecundity, egg size and reproductive effort respond to fish chemical cues directly or significantly alter the relationship between a trait and body size. We found no significant interactions between prey morph and the non-lethal presence of a top predator, suggesting that the effects of these two biological factors were additive or singularly independent. Overall it appears that C. flavicans is able to substantially modify several aspects of its biology, and while some changes appear mere consequences of resource limitation others appear facultative in nature. © Springer-Verlag 2009
Author Tom Springer reads from his book at the Michigan Writers Series
No full textAuthor Tom Springer credits his mother for developing his passion for reading and explains how he came to writing, calling himself "the least likely person to be standing up here". Springer, who works as chief editor and program manager for the Kellogg Foundation in Battle Creek, Michigan, describes his journey from a below average, blue-collar kid in southwest Michigan to the writing profession. He reads from his collection "Looking for hickories: the forgotten wildness of the rural Midwest", named a 2009 Michigan Notable Book. Springer interjects his observations on life in Michigan and its cultural history, while reading. He concludes by answering questions. Introduced by MSU Librarian Michael Rodriguez.

Phase equilibria of the Sn-Ag-Cu-Ni quaternary system at 210 degrees C
No full text[[abstract]]c2007 Springer - Sn-Ag-Cu alloys are the most promising Pb-free solders, and Ni is a common barrier layer material for the under-bump metallurgy. Although the Sn-Ag-Cu-Ni quaternary system is important for industry, no solid-phase equilibrium information is available. This study determines the equilibrium phase relationship of the Sn-Ag-Cu-Ni system at 210 degrees C. Quaternary alloys are prepared from the pure constituent elements and equilibrated at 210 degrees C. The equilibrium phases formed in the quaternary alloys are determined using scanning electron microscopy, electron probe microanalysis, and x-ray diffraction (XRD) analysis. The quaternary phase relationships are constructed from the quaternary experimental results and the 210'C isothermal sections of the equilibrium phase diagrams of its constituent ternary systems. Two isoplethal sections, 90at.%Sn and 80at.%Sn, of the 210 degrees C phase equilibria of the Sn-Ag-Cu-Ni system are determined. A Cu6Sn5 + Ni3Sn4 + Ag3Sn + Sn four-phase region is observed in both isopleths, and no ternary and quaternary intermetallic compounds are found.[[department]]化學工程學
SMALL PERTURBATIONS OF C-STAR-DYNAMICAL SYSTEMS
No full textIt is shown that if δ is the generator of a strongly continuous oneparameter group of *-automorphisms of a C*-algebra A and δ′ is an unbounded *-derivation of A with the same domain as δ, then δ+αδ′ is also a generator for all sufficiently small real numbers α. © 1979 Springer-Verlag
