Gauge Capability Studies for Attribute Data
JrJung Lyu

Repeatability and reproducibility (R&R) is adopted for analyzing measurement variation of a gauge (repeatability) and determining the variation of measurements by operators (reproducibility).  Gauge capability analysis is crucial element to improving a measurement system and is an integral part of efficient process control.  With numerous industries utilizing automated manufacturing processes and ...

Dinuclear Oxovanadium(IV) Thiolate Complexes with Ferromagnetically Coupled Interaction between Vanadium Centers
Hua-Fen Hsu


Our interest in studying vanadium chemistry is motivated from its important roles in biological systems and its medical application. Particularly, the interaction of high valent vanadium species with sulfur-containing bioligands such as cysteine and glutathione is relevant to the PTP inhibition by vanadate, the antidiabetic behavior of vanadium compounds, the redox conversion of vanadium in ...

Nano-indentation at the surface contact level: applying a harmonic frequency for measuring contact stiffness of self-assembled monolayers adsorbed on Au
Jiunn-Der Liao

Self-assembled monolayers usually include long-chain molecules, which are chemically bonded to the substrate via their head-group, while the molecular chains terminated by a particular functional group away from the substrate. Such an arrangement results in a well-ordered and densely-packed monomolecular film, giving the surface a new chemical identity or a nearly faultless modeling system for ...

Audit Partner Tenure, Audit Firm Tenure, and Discretionary Accruals: Does Long Auditor Tenure Impair Earnings Quality?
Yu-Chen Lin

Recent accounting scandals all around the world have raised the challenge about auditor independence. The U. S. congress pass the Sarbanes-Oxley Act in 2002, and require the period of auditor partner rotation at lease once every five years instead of seven years. The United Kingdom changed the requirement as well in 2003. Netherlands, Germany, and Japan adopt similar requirement about partner ...

High-Dielectric-Constant and Low-Loss Microwave Dielectric in the (1-x)Nd(Zn1/2Ti1/2)O3-xSrTiO3 System with a Zero Temperature Coefficient of Resonant Frequency
Cheng-Liang Huang

Miniaturization of dielectric devices for volume efficiency is a major requirement in modern microwave telecommunication technology such as 3G and GPS systems. Furthermore, the unique electrical properties of ceramic dielectric resonators have revolutionized the microwave-based wireless communications industry by reducing the size and cost of filter and antenna in circuit systems. ...
