Mismatches in Social Support and Psychosocial Adjustment to Breast Cancer.

Emotional support is known to provide psychosocial benefits for women with breast cancer, but women can experience a mismatch between support that is wanted and support that is received from their personal supporter. The role of wanted and unwanted support in psychosocial adjustment was examined in 79 women recovering from breast cancer. Four distinct patterns of desired support actions were found using cluster analysis. Patterns of wanted support were not related to better or worse psychosocial adjustment. However, a misalignment of support between the provider and the receiver significantly influenced psychosocial adjustment, and unwanted but received support (support commission) was uniquely associated with poor psychosocial adjustment. Clinical interventions using the support instrument could help match support providers' actions to receivers' preferences. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A Six-sigma approach for benchmarking of RP&M processes

This paper presents a methodology of using six-sigma quality tools for benchmarking of rapid prototyping & manufacturing (RP&M) processes. It involves the fabrication of a geometric benchmark part and a methodology to control and identify the best performance of the process to reduce the variablity in the fabricated parts. The approach is demonstrated with a case study based on the direct laser sintering (DLS) process for prototyping using plastic powder. In the case study an identified set of six-sigma/ statistical process control tools is employed to determine and best tune factors affecting the desired outcomes of the built parts.     

Distribution area demarcation for logistic centers under geographical information system decision support system

Demarcating distribution area of goods is often guided by the rule of thumb by business proprietors.However,this method seems to be unsuitable when the demand points increase to a certain large extent.The present work attempted to convert the problem of distribution area demarcation into a localized problem of warehouseing and networking,and tried to establish district-based planning mode based on location based heuristic (LBH).Two methods were used in this study:1) the manual method to construct the mathematical model and conduct simulation;2) the automatic method using TransCAD software of geographical information system (GIS) for simulation.By comparing the effects of the two methods,the research provides theoretical support for business proprietors to demarcate the distribution area rationally with the application of GIS system.The results show that GIS has very good graphics construction function to replace complex text,and the automatic demarcating mode with human-machine interaction provides a good business decision-making support.

EBPSK调制通信系统中非线性检测的研究

主要讨论扩展的二元相移键控（EBPSK）调制通信系统中的检测技术,以实现高频谱利用率的同时降低能耗。针对高效调制信号码元间差异性较小的特点,接收机利用特殊的冲击滤波器（SIF）将相位变化转化为寄生调幅,增加码元间的差异性,提高能量利用率。同时,引入了支持向量机（SVM）非线性检测方法,解决EBPSK系统中门限检测性能难以达到最优的问题,并给出了维数较少的统一特征向量选取方法。为了减少计算量,选择适用于EBPSK系统的SVM核函数并优化计算方法。仿真结果表明,SVM非线性检测在较少的特征向量维数和低采样率的条件下,可获得最多7 dB的信噪比增益。因而,在EBPSK调制通信系统中选择SVM方法不仅可以提升检测性能,而且抗干扰能力更强,对采样率的鲁棒性更好。

基于SVM的特征筛选方法及其若干应用

对于拟合问题，传统的模式识别特征筛选方法以各特征量对训练数据拟合能力的贡献为取舍标准，未考虑经验风险最小化和结构风险最小化间的差别，不能获得预报能力最强的特征筛选结果。为此我们提出了结合支持向量回归法与留一法的特征筛选新算法，并将它试用于镍氢电池材料和氧化铝溶出率两套实验数据集的特征筛选。
