Women in a box

This thesis is the written component of the exhibition that was be held from March 26 through April 9, 2015 in the gallery of 203 Design On Main, Iowa State University, Ames, Iowa. Women in a Box, the name of the thesis, explores the sexual imbalance and women\u27s to-be-looked-at-ness in patriarchal society, and concerns how mass media construct beauty standards and sexual attractiveness and the impacts on women\u27s identities. The artwork contains installations, pattern design, paintings, as well as video arts. This writing component documents the inspiration and intention of the artist in creating the work. It also documents the process, and details the academic and the conceptual development of the project. A variety of philosophy and theories ranging from psychoanalytical to sociological have been cited and explained regarding their relevance to the project

Design of an RF CMOS Power Amplifier for Wireless Sensor Networks

The Power Amplifier (PA) is the last Radio Frequency (RF) building block in a transmitter, directly driving an antenna. The low power RF input signal of the PA is amplified to a significant power RF output signal by converting DC power into RF power. Since the PA consumes a majority of the power, efficiency plays one of the most important roles in a PA design. Designing an efficient, fully integrated RF PA that can operate at low supply voltage (1.2V), low power, and low RF frequency (433MHz) is a major challenge. The class E Power Amplifier, which is one type of switch mode PA, is preferred in such a scenario because of its higher theoretical efficiency compared to linear power amplifiers. A controllable class E RF power amplifier design implemented in 0.13 µm CMOS process is presented. The circuit was designed, simulated, laid out, fabricated, and tested. The PA will be integrated as a part of a complete wireless transceiver system using the same process

Entangled SU(2) and SU(1,1) coherent states

Entangled SU(2) and SU(1,1) coherent states are developed as superpositions of multiparticle SU(2) and SU(1,1) coherent states. In certain cases, these are coherent states with respect to generalized su(2) and su(1,1) generators, and multiparticle parity states arise as a special case. As a special example of entangled SU(2) coherent states, entangled binomial states are introduced and these entangled binomial states enable the contraction from entangled SU(2) coherent states to entangled harmonic oscillator coherent states. Entangled SU(2) coherent states are discussed in the context of pairs of qubits. We also introduce the entangled negative binomial states and entangled squeezed states as examples of entangled SU(1,1) coherent states. A method for generating the entangled SU(2) and SU(1,1) coherent states is discussed and degrees of entanglement calculated. Two types of SU(1,1) coherent states are discussed in each case: Perelomov coherent states and Barut-Girardello coherent states.Comment: 31 pages, no figure

Phonon-assisted tunneling in asymmetric resonant tunneling structures

Based on the dielectric continuum model, we calculated the phonon assisted tunneling (PAT) current of general double barrier resonant tunneling structures (DBRTSs) including both symmetric and antisymmetric ones. The results indicate that the four higher frequency interface phonon modes (especially the one which peaks at either interface of the emitter barrier) dominate the PAT processes, which increase the valley current and decrease the PVR of the DBRTSs. We show that an asymmetric structure can lead to improved performance.Comment: 1 paper and 5 figure

THE EXPLORATION OF ANIMAL PHYSIOLOGY COURSE CONSTRUCTION

In order to adapt to the modernization of education and the development of education in colleges and universities, it is necessary to reform and explore the course system, organization and clinical practice of animal physiology curriculum, and to strengthen the software and hardware construction of the course. Focusing on the student-centered principle, we plan to maximize the effective use of modern information technology and improve the outcome of teaching process. We aim to help students grasp the knowledge, at the same time, pay attention to the cultivation of students' comprehensive capabilities.  Article visualizations
