A dual active-restrictive approach to incorporating environmental flow targets into existing reservoir operation rules
Jenq-Tzong Shiau

Deterioration of riverine health and biodiversity of the downstream riverine ecosystems caused by construction and operation of dams are well known. The natural flow regime has been recognized a paradigm for river conservation and restoration, which compromises of five components of flow regime, i.e., magnitude, duration, timing, frequency, and rate of change (Poff et al., 1997). That is, …

Structural Characteristics and Annealing Effect of ZnO Epitaxial Films Grown by Atomic Layer Deposition
W. F. Hsieh

Structural characteristics of the ZnO epitaxial films grown on c-plane sapphire by the atomic layer deposition were thoroughly studied. The in-plane axes of the c-plane ZnO layers are predominantly aligned with that of the sapphire substrate, yielding the relationship of {10-10}ZnO//{10-10}Al2O3. The structure of the ZnO epi-films exhibits significantly improvement upon thermal annealing. …

Researchers Develop Disease Animal Model for Study of Frontotemporal Lobar Degeneration, a Common Cause of Dementia
Kuen-Jer Tsai

Frontotemporal lobar degeneration (FTLD) is clinically associated with atrophy in the frontal lobe and temporal lobe of the brain, memory loss, aphasia and sometimes with motor neuron disease (MND). In the over 65 age group, FTLD is the fourth most common cause of dementia after Alzheimer's disease, dementia with Lewy bodies and vascular dementia. In below-65 age group, it is the second most …

Velocity Field Construction for Contour Following Tasks Represented in NURBS Form
Ming-Yang Cheng

INTRODUCTION
Generally speaking, in multi-axis contour following tasks, reduction in tracking error does not guarantee that the contour error will also be reduced. To deal with this problem, Li and Horowitz proposed the Velocity Field Control (VFC) approach [1,2]. Since the constructed velocity field is a function of position only, the design of controllers can place emphasis on reducing …
