Fabrication of Nanoscale Features on Surfaces

A method to form nanofeatures on the surface of a material by utilizing a prefabricated polymer nanostructures is proposed. A means by which the polymer structures can be produced is discussed. The advantages and disadvantages of this process and other nanolithography processes are evaluated

Preliminary Examination of the Effects of Time and Flexural Direction on an Anisotropic Geosynthetic Cementitious Composite Mat

The significance of this research was to determine the effect the main fabric weave direction and cure time has on the maximum load of 0.34 inch anisotropic Geosynthetic Cementitious Composite Mat sample coupons. Two series of tests were run. The first used a three-point bend test on the material samples with varying cure times to determine the average maximum load associated with each. The second series of testing used followed ASTM D8030/D8030M - 16 for sample preparation and ASTM D8058 - 17 for testing to determine the flexural strength and modulus of elasticity of the test samples with and against the main machine weave pattern. The results indicated no significant difference between the variations of cure times. However, the results did indicate a significant difference between flexural strength of with and against machine weave

Capital Punishment: Evaluating an Investor\u27s Secondary Copyright Infringement Liability after \u3ci\u3eVeoh\u3c/i\u3e

In UMG Recordings, Inc. v. Veoh Networks, Inc., the U.S. District Court for the Central District of California considered claims that investors in a privately-held corpor-ation were secondarily liable for copyright infringement. The Veoh court findings, which set out current secondary copy-right infringement law, provide guidance for investors by clarifying their potential liability for copyright infringement committed by the company in which they invested. However, because the decision was fact-specific, this guidance is incomplete. For example, the court found that the investor neither controlled the infringing activities nor reaped direct financial benefit from them. This leaves open for further decisions the situation in which only one factor is present. In addition, Veoh bases secondary liability on such subjective concepts as “control,” “supervision,” “ability to supervise,” “reason to know,” “material assistance,” “encouragement to infringe,” and “direct financial interest.” Therefore, future cases involving similar facts are susceptible to contrary results based on the court’s interpretation of these concepts. This Article examines the standards established and the cases distinguished by the Veoh court to determine conditions under which an investor may be held liable for the copyright infringement of the investment target and proposes practical steps to minimize liability exposure

Fair Notice: Providing for Electronic Document Transmissions to Shareholders in Washington State

In 2008, Washington State amended Wash. Rev. Code § 23B.01.410 to allow electronic transmission of materials accompanying corporate notices to shareholders. This amendment, combined with an earlier change allowing corporations operating within the state to notify shareholders through certain types of electronic transmissions, incorporated several Securities and Exchange Commission (SEC) suggestions to expand the authorized uses of Internet-based technology to communicate with shareholders. However, corporations operating across state lines are subject to a complex variety of state notice requirements. These differences create an uneven national standard for which types of electronic communication constitute sufficient notice. This statutory variance compels corporations to fulfill certain consent, availability, and confirmation requirements that are not uniform among the various states. This Article examines the SEC rules related to electronic shareholder notification, surveys the applicable laws in all 50 states, and analyzes the coverage provided by the recent amendments to the Washington statute

Voltage transfer function as an optical method to characterize electrical properties of liquid crystal devices

The voltage transfer function is a rapid and visually effective method to determine the electrical response of liquid crystal (LC) systems using optical measurements. This method relies on cross-polarized intensity measurements as a function of the frequency and amplitude of the voltage applied to the device. Coupled with a mathematical model of the device it can be used to determine the device time constants and electrical properties. We validate the method using photorefractive LC cells and determine the main time constants and the voltage dropped across the layers using a simple nonlinear filter model

Light-activated modulation and coupling in integrated polymer-liquid crystal systems

We explore the transfer of an incident light pattern onto the liquid crystal (LC) bulk in a photorefractive cell through an integrated photoconducting layer that modulates the electric field applied to the device. The electrical properties and the strength of modulation are investigated as a function of the incident light intensity as well as the frequency and amplitude of the applied voltage, for two LCs with very different electrical conductivity. A simplified electrical model of the cell is proposed, demonstrating that the LC conductivity is a key factor determining the beam-coupling strength
