The Department of Statistics at the University of California at Berkeley will purchase 18 SUN Ultrasparc workstations which will be dedicated to the support of research in the mathematical sciences. The equipment will be used for many research projects, including: Genetics (Terry Speed) testing for genetic locus heterogeneity, investigating the power effects of interference, estimating recombination fractions, modeling crossover interference, identification of quantitative trait loci, location of disease genes, and estimation of phylogenetic relationships between species. Wavelets (David Donoho) research includes basis pursuit, time frequency signal analysis, and digital communications processing, Biological and Environmental Problems (John Rice) analysis of ion channel recordings, analysis of oceanographic measurements, and modeling hormonal profiles ( David Brillinger) analyzing nerve cell spike trains, trajectories of mammalian dives, motion of meteorological fields, and seismic risk analysis. Astrophysics(Philip Stark) modeling the structure of the sun, algorithms for the analysis of satellite data. Methodology (Leo Breiman) study of the structure of neural nets, prediction of multiple time series, stabilizing nonparametric high dimensional predictors in regression and classification, using categorical variables in nearest neighbor classification, and parallelizing CART over a workstation network. Stochastic Processes (David Aldous) Monte Carlo experiments in spatial stochastic processes. (Ching-Shui Cheng) nonregular experimental designs

加州大学伯克利分校的统计系将购买18台SUN超声帕克工作站，专门用于支持数学科学的研究。该设备将用于许多研究项目，包括：遗传(特里速度)基因座异质性测试，调查干扰的功率效应，估计重组比例，建立交叉干扰模型，识别数量性状基因座，定位疾病基因，以及评估物种之间的系统发育关系。小波(David Donoho)的研究包括基寻踪、时频信号分析和数字通信处理、离子通道记录的生物和环境问题分析(John Rice)、海洋测量分析和荷尔蒙模型(David Brillinger)(David Brillinger)分析神经细胞尖峰训练、哺乳动物潜水轨迹、气象场运动和地震风险分析。天体物理学(菲利普·斯塔克)对太阳的结构建模，用于分析卫星数据的算法。方法论(Leo Breiman)研究神经网络结构、预测多个时间序列、在回归和分类中稳定非参数高维预测值、在最近邻分类中使用分类变量，以及在工作站网络上并行化CART。随机过程(David Aldous)蒙特卡罗空间随机过程实验。(郑经水)非常规实验设计
