An Introduction to the Methods of Relativistic Molecular Quantum Mechanics

為了解決Electronics的問題，作者Wilson, Stephen 這樣論述：

Molecular electronic structure calculations have assumed increasing importance in a wide range of research fields. Applications abound in fields as diverse as molecular electronics and pharmacology, radioastronomy and organic synthesis. The vast majority of contemporary molecular electronic struc

ture studies are performed within the framework of non-relativistic quantum mechanics. However, recent years have seen a growing recognition of the importance of relativistic effects in molecules, especially in systems containing heavy atoms. This has fuelled the development of methods for relativis

tic molecular electronic structure studies. This book describes the essential theoretical and computational apparatus for a relativistic quantum chemistry.

優化採購管理之實務研究

為了解決Electronics的問題，作者陳美芳 這樣論述：

電子製造業面對半導體物料交期的不確定性、訂單給予供應商前置時間（Lead Time）不足、臨時更改設計、客戶端的需求變化瞬息萬變加上不可抗力的偶發事件和天災人禍在在考驗管理者的因應能力。藉由個案公司了解可能面臨的供應鏈危機接續不上，如何降低生產線停工的危機及後續損失賠償降到最低。本研究期可提供企業優化現有的採購作業流程，持續改善採購管理效率之建議，並建議品牌廠商採購管理應著重於如何與供應商、外包廠商建立長期夥伴關係，進而持續改善作業流程及降低成本、提升企業採購總體績效，並且能讓企業對緊急訂單需求作出更快速的反應。在本研究討論中，透過對個案公司降低供應鏈風險增進採購效率的觀念探討分析，從而得出

結論，採購經過資訊系統協助更可達成風險共擔與資訊共享觀念，風險成本及代工廠轉運成本均可下降、對前置時間不足的緊急訂單應變能力提升。

滾珠螺桿溝槽研磨轉速控制對螺帽品質與砂輪壽命之研究

為了解決Electronics的問題，作者蘇承緯 這樣論述：

中文摘要 隨著科技的進步，電子產業、半導體業、航太產業、工業加工業、車用工業等領域不斷在進步，使得在加工物件上的需求大增。且科技不斷的進步，各行業對產品的精密度、精準度要求也越來越高，故在磨削的過程中，砂輪對加工物件的磨耗參數設定是相當重要的。 本論文之主要研究為透過修改與設定內徑研磨用主軸的轉速、參數，並藉由砂輪磨削對滾珠螺桿中內螺紋的成型變化作為實驗對象，依照歌德型滾珠螺桿的原理為主要探討，並透過精密輪廓量測儀測量內螺紋的螺紋角與粗糙度之結果。利用紀錄每個加工物件測量與參數修改之結果，並利用這些量測與參數修改的分析，找出生產中對品質與速度最好的參數，並利用管制上下限規範分析後，能夠提

前預防不良率的狀況發生，並且延續砂輪在研磨過程中更換的壽命與確保品質的穩定度。 而由研究結果得知砂輪與參數的搭配關係，進而影響了加工物件的內螺紋的螺紋角度、粗糙度。並透過減少修整砂輪量，提高研磨過程中轉速與修整砂輪轉速的過程中，確保牙型角度、粗糙度不變，且能延續砂輪壽命，增加成本效益之結果作為探討，而如何在品質與成本效益中找到最佳平衡點為後續所要面臨的重要課題。
