技术支持工程师的业绩评价体系的研究

由于笔记本电脑的设计中大部分机构组件和电子元器件都是在设计过程中就植入的,并且不能轻易更换。所以,各个组件和电子元器件商必须在项目设计过程中为笔记本电脑的设计者提供有效和及时的技术支持,并对项目进行质量和进度跟踪,同时在设计的整个阶段提供必要的产品信息,和设计资料更新,以使项目的顺利进行,减少项目风险和开发成本。本文主要分析和讨论目前行业内对技术支持工程师的业绩评价体系的现状及存在的问题,并且提出改进的方法。     

命运的转折,生命的丰润

Show——倾听心声:在我看来,成长的关键因素只有两个:引领和思考。没有引领,仅凭自己的才智和见识,那个过程是缓慢而充满危险的;没有思考,再多的汗水和付出也不能使自己成长为巨人。而引领和思考从哪里来?就来自名家的指引和书籍的启发。恰好,我幸运地站在了两者的交叉口。

利用MODIS EVI时间序列数据分析福建省植被变化(2000~2017年)

以全国森林覆盖率最高的福建省为研究对象,利用2000~2017年夏季的MODIS EVI植被指数数据和气象与非气象因子进行协同分析,以揭示近17年福建植被的时空变化及其影响因子。结果表明:研究期内福建的EVI均值整体上升,从2000年的0.454上升至2017年的0.505,17 a间上升了11.2%,表明福建省的植被整体处于变好的状态,且在中部和西南部的变化最明显。相关分析表明,在研究期内,气象因子(气温和降水)对EVI变化的影响不显著,植被的变好主要为非气象因子的作用。EVI的提高主要得益于2003年福建省建设生态省后森林覆盖率的提高,并和2012年开始的水土流失治理有明显关系,这说明人类活动的积极作用对福建植被的变好起到了关键的作用。     

INTRODUCTION TO THE SPECIAL ISSUE ON CASE-BASED REASONING IN THE HEALTH SCIENCES

There has been an explosion of interest in health sciences applications of case-based reasoning (CBR), not only in the traditional CBR in medicine domain, but also in bioinformatics, enabling home health-care technologies, CBR integration, and synergies between CBR and knowledge discovery. This special issue features the best papers from the third workshop on CBR in the health sciences, held at ICCBR-05 in Madrid. It is the third in a series of exciting workshops, the first two of which were held at ICCBR-03, in Trondheim, Norway, and at ECCBR-04, in Madrid, Spain. The nine high-quality papers introduced here represent the research and experience of twenty-two authors working in eight different countries on a wide range of problems and projects. These papers illustrate some of the major trends of current research in CBR in the health sciences, and represent overall an excellent sample of the most recent advances of CBR in the health sciences.     

Stability of nonlinear hybrid dynamical systems with time delay via sum of squares decomposition

Considering an infinite number of eigenvalues for time delay systems, it is difficult to determine their stability. We have developed a new approach for the stability test of time delay nonlinear hybrid systems. Construction of Lyapunov functions for hybrid systems is generally a difficult task, but once these functions are found, stability’s analysis of the system is straight-forward. In this paper both delay-independent and delay-dependent stability tests are proposed, based on the construction of appropriate Lyapunov-Krasovskii functionals. The methodology is based on the sum of squares decomposition of multivariate polynomials and the algorithmic construction is achieved through the use of semidefinite programming. The reduction techniques provide numerical solution of large-scale instances; otherwise they will be computationally infeasible to solve. The introduced method can be used for hybrid systems with linear or nonlinear vector fields. Finally simulation results show the correctness and validity of the designed method.

Analogic: Inference beyond logic

Analogic is the unique class of many-valued, non-monotonic logics which preserves the richness of inferences in (Boolean) logic and the manipulability of (Boolean) algebra underlying logic, and, in addition, contains a number of unexpected, emergent properties which extend inferentiability in non-trivial ways beyond the limits of logic. For example, one such inference is rada (reductio ad absurdum, reasoning by contradiction, but now in the absence of excluded middle). This is important to retain since direct proofs of many theorems are not known. Another example is chaining. Transitivity is uncommon in many-valued logics; however, in analogic we can carry out inferences in either direction even through weak links in the chain. The latter, impossible in logic, simulate intuitive leaps in reasoning. Protologic effects inferences using only (n+1) implications which require 2ⁿ implications in logic. Indeed protologic has no counterpart in logic, or any other form of reasoning. Analogic is useful in formulating problems which are largely inferential including document and pattern classification and retrieval. These inference properties, long sought after in alternative logics by adding appropriate axioms or other indicative implicit or explicit restrictions, are now available in analogic, in turn the result of removing an axiom and letting inferences become many-valued.     

Food security problems in sub-Saharan Africa: Operations Research as a tool of analysis

For many years, the author has been involved in teaching and research in the use of Operations Research as a tool of analysis to study food security problems in sub‐Saharan Africa, in particular, grass root problems of poor farmers. The paper presents an introduction to the way Operations Research methods have been applied in case studies and research projects, and discusses in retrospect the author's views on the strengths and limitations of the application of Operations Research. The paper has in particular been written for people who are not familiar with applications of Operations Research in agriculture, and are interested to learn about its potential usefulness in practice. The retrospective part is largely based on food security studies in e.g. Tanzania, Burkina Faso, Bénin, Togo and Eritrea and on participation in several interdisciplinary research programmes in Africa.
