Managing Power Consumption in Networks on Chips
Energy management low power regenerative stochastic processes system analysis and design
2015/7/6
In this paper, we present a new methodology for managing power consumption of networks-on-chips (NOCs). A power management problem is formulated for the first time using closed-loop control concepts. ...
MINRES-QLP: A KRYLOV SUBSPACE METHOD FOR INDEFINITE OR SINGULAR SYMMETRIC SYSTEMS
MINRES Krylov subspace method Lanczos process
2015/7/3
CG, SYMMLQ, and MINRES are Krylov subspace methods for solving symmetric
systems of linear equations. When these methods are applied to an incompatible system (that is,
a singular symmetric least-sq...

2015/7/3
Biological processes such as metabolism, signaling, and macromolecular synthesis can be modeled as
large networks of biochemical reactions. Large and comprehensive networks, like integrated networks ...
LSRN: A PARALLEL ITERATIVE SOLVER FOR STRONGLY OVER- OR UNDERDETERMINED SYSTEMS
linear least squares overdetermined system
2015/7/3
We describe a parallel iterative least squares solver named LSRN that is based on
random normal projection. LSRN computes the min-length solution to minx∈Rn Ax − b2, where
A ∈ Rm×n with m n ...
PROXIMAL NEWTON-TYPE METHODS FOR MINIMIZING COMPOSITE FUNCTIONS
convex optimization nonsmooth optimization
2015/7/3
We generalize Newton-type methods for minimizing smooth functions to handle a
sum of two convex functions: a smooth function and a nonsmooth function with a simple proximal mapping.
ON THE STABILITY OF CHOLESKY FACTORIZATION FOR SYMMETRIC QUASIDEFINITE SYSTEMS*
indefinite systems symmetric quasidefinite (sqd) systems
2015/7/3
Sparse linear equations Kd r are considered, where K is a specially structured
symmetric indefinite matrix that arises in numerical optimization and elsewhere. Under certain
conditions, K is quaside...
Cholesky-based Methods for Sparse Least Squares: The Beneˉts of Regularization
Sparse Least Squares Regularization
2015/7/3
We study the use of black-box LDL

factorizations for solving the augmented
systems (KKT systems) associated with least-squares problems and barrier methods
for linear programming (LP). With judi...
SOLUTION OF SPARSE RECTANGULAR SYSTEMS USING LSQR AND CRAIG
Conjugate-gradient method least squares regularization
2015/7/3
Various methods for symmetric and unsymmetric systems are reviewed to illustrate
the parallels . We see that the extension of Craig's method closes a gap in existing
theory. However, LSQR is more ec...
WHY ORGANIZATIONS DON’T “KNOW WHAT THEY KNOW”: COGNITIVE AND MOTIVATIONAL FACTORS AFFECTING THE TRANSFER OF EXPERTISE
COGNITIVE MOTIVATIONAL FACTORS AFFECTING
2015/7/3
In today’s economy, competitive success is increasingly based on possessing knowledge
and intellectual capital rather than financial or other “hard” assets. For instance, Grant (1996)
has argued t...

Ronald A. Howard has been Professor in the Department of Engineering-Economic Systems (now the Department of Management Science and Engineering) in the School of Engineering of Stanford University sin...
An fMRI Investigation of Racial Paralysis
Behavior Race Characteristics Judgments Decision Choices and Conditions Personal Characteristics
2015/5/13
We explore the existence and underlying neural mechanism of a new norm endorsed by both black and white Americans for managing interracial interactions: "racial paralysis," the tendency to opt out of ...
中国“宅一族”群体日益壮大，但目前学界缺乏对“宅”的测评工具。宅的行为表现、心理特征和对宅的态度是相互关联但又有所区别的概念，有关宅现象的研究需要根据研究目的的不同选取相应的宅量表。可以将宅的评价量表分为宅行为自评量表（“行为宅”的判定标准）和宅心理特征量表（“心理宅”的判定标准）进行设计与信效度检验。结果表明，这两份量表具有良好的内部一致性及重测信度、内容效度、区分效度和效标效度，可以作为宅现象...
通过严格控制实验程序，首次考察认知方式和线索提示对8岁、10岁、12岁学龄儿童EBPM的影响，并分析学龄儿童EBPM的发展趋势后发现：（1）8—12岁儿童EBPM能力仍在持续向前发展；（2）认知方式在儿童EBPM加工过程中扮演着重要角色，对年幼儿童（8岁和10岁）来说，场独立者更善于完成EBPM任务，而对12岁儿童来说，场独立者与场依存者都可以很好地完成EBPM任务；（3）线索提示有助于学龄儿童完...
“学校选择运动”是20世纪80年代美国保守主义教育改革的重要组成之一，发端于保守主义者对进步主义者构建的“单一的最优制度”的反思，蕴含着保守主义阵营中新保守主义与传统派对公共教育政策文本中“选择”符号的不同理念，体现了专业化与市场化两大逻辑对“选择”这一政策符号解释权的争夺，并在特许学校的制度实践中达成妥协。由此，创立并强化了一套由保守主义意识形态主导的公共教育体系。
