Using Java And Html For Linear Algebra Instruction, Jonathan R. Senning May 1997

Using Java And Html For Linear Algebra Instruction, Jonathan R. Senning

ACMS Conference Proceedings 1997

This paper addresses some of the issues involved with using the HTML, JavaScript and Java to develop and serve a sequence of laboratory modules for use in teaching linear algebra. Attention is paid to the rationale for this approach as opposed to the more traditional approach of laboratory exercises executed using MATLAB or some similar computational tool. Several methods to display mathematics with HTML are described. Some implementation detail and a brief description of the HTML and Java based Linear Algebra Visualization Assistant (LAVA) is presented.

Self-Organizing File Cabinet, Dawn Lawrie

Dartmouth College Undergraduate Theses

This thesis presents a self-organized file cabinet. This file cabinet uses electronic information to augment the physical world. By using a scanner to transform documents into electronic files, the self-organized file cabinet can index the documents on visual and textual information. The self-organized file cabinet helps the user find the documents at a later date. The focus of this thesis is on the design and evaluation of the self-organized file cabinet. User studies show that this tool is natural to use.

Syntheses And Characterizations Of Unsymmetrical Porphyrins As Photosensitizers For A Solid-State Solar Cell, Yinping Zhao May 1997

Syntheses And Characterizations Of Unsymmetrical Porphyrins As Photosensitizers For A Solid-State Solar Cell, Yinping Zhao

Dissertations and Theses

Solar light is the most important source of regenerative energy and represents mankind's only inexhaustible energy source. One of today's most promising tools to make use of solar energy is its direct conversion into electrical energy in a photovoltaic cell. The practical use of these solar cells depends on the price of the devices and therefore of the obtained energy. The conventional silicon cells, although efficient, are expensive for common consumer applications. The Grätzel cell is a photovoltaic system for harvesting the sun's energy that operates at about 10-15% overall efficiency, like a conventional solar cell, but does it at …

Effects Of Tunneling Electrons And Local Field On Nanometer Region Solid / Liquid Interfacial Reactions ——Potential Controlled Stm Induced Nanoscale Modification Of H Terminated Si(111) Surfaces, Zhaoxiong Xie, Xiongwei Cai, Caihui Shi, Bingwei Mao, Zhaowu Tian May 1997

Effects Of Tunneling Electrons And Local Field On Nanometer Region Solid / Liquid Interfacial Reactions ——Potential Controlled Stm Induced Nanoscale Modification Of H Terminated Si(111) Surfaces, Zhaoxiong Xie, Xiongwei Cai, Caihui Shi, Bingwei Mao, Zhaowu Tian

Journal of Electrochemistry

H-terminated n-Si(111) surface was found to be etched in 0.5% HF solution in nanometer scale while scanning the STM tip when the substrate potential was somehow lower than the open circuit potential at tunneling condition of Vb=+1.0 V (tip positive), It=1 nA. Much more stable Si surface was achievable at potentials much more negative than the open circuit potential (such as 500 mV negative to OCP) under the same tunneling condition. Furthermore, the etching rete at less negative potential was found to be somehow related to the tunneling current. These results indicate that the STM induced …

Electrodeposition Of Amorphous Fe-Cr Alloy Coating, Danhong Cheng, Weiyi Xu, Yiqin Qin, Liqun Hua, Zhongyan Zhang

Journal of Electrochemistry

The amorphous Fe-Cr alloy coatings were obtained by controlling the composition of bath operation conditions. It was found that the pH value, the current density and the content of chromium in Fe-Cr alloy coatings effect the amorphous structure of the coatings. The result of anodic polarization shows that the corrosion resistance of the amorphous coatings in acidic media is higher than the corrosion resistance of the crystal ones.

An Analysis On The Microstructure Of Electrodeposited Zro2-Ni Functionally Graded Materials, Chengjun Quan, Xinghua Xiang, Jingchuan Zhu, Zhongda Yin

Journal of Electrochemistry

The electrodeposited ZrO2-Ni functionally graded coating was fabricated by controlling the ZrO2 concentration in the bath, and the microstructure was analyzed by X-Ray Diffraction (XRD) and Electron Probe Microanalysis (EPMA). The results show that the functionally graded coating has excellent compositional gradient distribution from the substrate to the surface. The content of ZrO2 is up to 14.4 vol% in the surface layer and the coating consists of the t-ZrO2, m-ZrO2 and Ni phases. Owing to the ZrO2 particles pressed by Ni atoms during electrodepositing, t→m transformation has occurred.

The technique is of the same applicability as that of CZE, not limited to the protein like big molecules, with greatly improved efficiency of separation and enrichment. Advantages of this novel technique are: 1. Since large volume of dilute sample solution can be injected and very narrow and concentrated zones can be obtained, extremely dilute sample can be analyzed by this novel technique in comparison with CZE. 2.

Electroluminescence Of Photoelectrochemically Etched N+-Si, Guozheng Li, Chengqian Zhang, Xiumei Yang May 1997

Electroluminescence Of Photoelectrochemically Etched N+-Si, Guozheng Li, Chengqian Zhang, Xiumei Yang

Journal of Electrochemistry

Porous silicon with micrometer size pores, which is made on n+-Si by photoelectrochemically etched, has electroluminescent property. Each monochromic intensity and wavelength range of luminescent spectra depend on polarized potential. The intersity and the stability of cathodic electroluminescence is high than those of anodic one. Voltammetric behavior before quenching indicated that the electrochemical reactions of some surface species are involved in except the reduction of S2O82-, which leads to radiative recombination. The energy band diagram based on n+-Si(Eg=1.1 eV)/PS(Eg=1.8 eV) junction is proposed.

Journal of Electrochemistry

The influence of dextran and its anion derivates (blue dextran, cibacron blue dexran, fluoresceinythiocarbamoyl dextran) on the electrofusion of barley protoplasts has been investigated. It was found that as a kind of neutral surface active agent, dextran could promote the electrofusion, but these anion derivates could decrease the electrofusion yield. The phenomena were discussed from the view of adsorption of additives on the cell membrane.
