The ability to prepare single-crystal faces has become central to developing and testing models for chemistry at interfaces, spectacularly demonstrated by heterogeneous catalysis and nanoscience. This ability has been hampered for hexagonal ice, Ih--a fundamental hydrogen-bonded surface--due to two characteristics of ice: ice does not readily cleave along a crystal lattice plane and properties ...

Trajectory tracking of nonlinear dynamical systems with affine open-loop controls is investigated. The control task is to enforce the system state to follow a prescribed desired trajectory as closely as possible. We introduce exactly realizable desired trajectories as these trajectories which can be tracked exactly by an appropriate control. Exactly realizable trajectories are characterized mat...

This research examines the aspects of notary's responsibility as a public servant, specifically regarding individuals with disabilities, in relation to Law Number 25 2009 on Public Services. The notary is involved and has provide services public. In this study, researcher addresses two topics: duties responsibilities use Braille script desired deeds. To answer these discussions, author adopts n...

The Cross-Classified Mixed Effects Model (CCMEM) has been demonstrated to be a flexible framework for evaluating reliability by measurement specialists. Reliability can estimated based on the variance components of test scores. Built upon their accomplishment, this study extends CCMEM used validity evidence. Validity is viewed as coherence among elements system. As such, evaluated user-reasoned...
