The Optimization Of The Reliability And Construction Cost Of Rc Bridges, Wen-Hu Tsao, Chi-Way Lin, Ming-Te Liang, Wen-Lung Wen-Lung Tsao Tsao

Journal of Marine Science and Technology–Taiwan

In this paper, the relationship between reliability and engineering system construction cost for obtaining optimum reliability was studied. This proposed approach was applied to the repair alternatives of existing reinforced concrete (RC) bridges for acquiring the result of optimization analysis. According to the D(degree) E(extent) R (relevancy) evaluation method, which is widely used by civil engineers in Taiwan the existing RC bridges with and without stridden rivers can be divided into 21 and 17 substructures, respectively. The use of the weighting value and the cost relation is to attain the relationship between the total engineering system construction cost and the …

We report on the first joint search for gravitational waves by the TAMA and LIGO collaborations. We looked for millisecond-duration unmodeled gravitational-wave bursts in 473 hr of coincident data collected during early 2003. No candidate signals were found. We set an upper limit of 0.12 events per day on the rate of detectable gravitational-wave bursts, at 90% confidence level. From software simulations, we estimate that our detector network was sensitive to bursts with root-sum-square strain amplitude above approximately 1-3×10-19Hz-1/2 in the frequency band 700-2000 Hz. We describe the details of this collaborative search, with particular emphasis on its advantages and …

Application Of Fuzzy Soil Classification In Visualizing 3-D Soil Strata, Jing-Wen Chen

Journal of Marine Science and Technology–Taiwan

The distribution of soil classes is an important factor in engineering design. In order to generate the soil class map, fuzzy soil classifications were developed to provide the means to characterize and quantify the soil classes, and then the spatial distribution of soil class can be interpolated by geostatistical method. For establishing continuous class soil maps, this paper present an index of fuzzy soil classification generated from principal component analysis (PCA). The ability of classification of the index is tested with a soil database which including 9,260 soil samples, and the accurate rate of simulation was 91.7%. There are two …

Detection Of Pathogenic Bacteria And Fecal Enterococci In Recreational Water With An Evanescent Wave Fiber Optic Biosensor, Maria Theresa Trindade

USF Tampa Graduate Theses and Dissertations

Development of a rapid method for the detection of fecal enterococci and pathogenic microorganisms in beach water was attempted utilizing an evanescent wave fiber optic biosensor. Various assay formats including a sandwich immunoassay were tested in the development of a rapid assay. Fluorophore labeled antibodies were used for specific detection of bacteria captured or adsorbed directly to the surface of a polystyrene fiber optic waveguide. Binding of the fluorescent labeled antibody to its specific target or binding of a fluorescent labeled anti-IgG within 100-1000 nm of the waveguide surface caused excitation of the fluorescent conjugate resulting in a quantifiable signal. …

An Adaptive Nonlinear Fuel Injection Control Algorithm For Motorcycle Engine, Tung-Chieh Chen, Chiu-Feng Lin, Chyuan-Yow Tseng, Chung-Ying Chen

Journal of Marine Science and Technology–Taiwan

The purpose of this research is to apply an adaptive fuel injection control algorithm on a motorcycle engine and evaluate its performance. A highly nonlinear switching type EGO sensor is used to measure the air fuel ratio of the engine. In the research, the nonlinear control algorithm is developed based on a Lyapunov function. Furthermore, an observer is also applied to estimate the air flow rate into the combustion room. The results show that the air fuel ratio and engine speed are stable under steady manoeuvres and the air-fuel ratio values are satisfactory.

Laser-Controlled Local Magnetic Field With Semiconductor Quantum Rings, Yuriy V. Pershin Dr, Carlo Piermarocchi

Faculty Publications

We analyze theoretically the dynamics of N electrons localized in a narrow semiconductor quantum ring under a train of phase-locked infrared laser pulses. The pulse sequence is designed to control the total angular momentum of the electrons. The quantum ring can be put in states characterized by strong currents. The local magnetic field created by these currents can be used for a selective quantum control of single spins in semiconductor systems. The current generation in quantum rings with finite width is also studied.

Spin-Photovoltaic Effect In Quantum Wires Due To Intersubband Transitions, Arkady Fedorov, Yuriy V. Pershin Dr, Carlo Piermarocchi

Faculty Publications

We consider the current induced in a quantum wire by external electromagnetic radiation. The photocurrent is caused by the interplay of spin-orbit interaction (Rashba and Dresselhaus terms) and an external in-plane magnetic field. We calculate this current using a Wigner functions approach, taking into account radiation-induced transitions between transverse subbands. The magnitude and the direction of the current depends on the Dresselhaus and Rashba constants, strength of magnetic field, radiation frequency, and intensity. The current can be controlled by changing some of these parameters.

Kondo Resonances And Anomalous Gate Dependence In The Electrical Conductivity Of Single-Molecule Transistors, L H. Yu, Z K. Keane, Jacob W. Ciszek, L Cheng, J M. Tour, T Baruah, M R. Pederson, D Natelson

Chemistry: Faculty Publications and Other Works

We report Kondo resonances in the conduction of single-molecule transistors based on transition metal coordination complexes. We find Kondo temperatures in excess of 50 K, comparable to those in purely metallic systems. The observed gate dependence of the Kondo temperature is inconsistent with observations in semiconductor quantum dots and a simple single-dot-level model. We discuss possible explanations of this effect, in light of electronic structure calculations.

Simulation Of Phonon-Assisted Band-To Band Tunneling In Carbon Nanotube Field-Effect Transistors, Siyuranga O. Koswatta, Mark S. Lundstrom, M. P. Anantram, Dmitri E. Nikonov

Other Nanotechnology Publications

Electronic transport in a carbon nanotube metal-oxide-semiconductor field effect transistor (MOSFET) is simulated using the nonequilibrium Green’s functions method with the account of electron-phonon scattering. For MOSFETs, ambipolar conduction is explained via phonon-assisted band-to-band (Landau–Zener) tunneling. In comparison to the ballistic case, we show that the phonon scattering shifts the onset of ambipolar conduction to more positive gate voltage (thereby increasing the off current). It is found that the subthreshold swing in ambipolar conduction can be made as steep as 40 mV/decade despite the effect of phonon scattering.

Improving Community College Board Governance Using A Technology Based Board Management System, Teresa Walsh

Regis University Student Publications (comprehensive collection)

Higher education boards are turning to accountable board leadership and macroengagement discussions in lieu of traditional micromanagement of operations. The Policy Governance© model integrates unique principles designed to enable accountable board leadership. This paper describes an Action Research project that was conducted with the Board of Yavapai College. The Board adopted Policy Governance© but failed to practice its tenets. This research seeks to demonstrate whether a technology based board management system, OurBoardroom, that fully implements Policy Governance©, can assist the Board in the practice of the model. Findings indicate that the technology application that provides a template for all aspects …

Preparative Synthesis Of Dtdp-L-Rhamnose Through Combined Enzymatic Pathways, Young Bok Abraham Kang, Yung-Hun Yang, Kwang-Won Lee, Sun-Gu Lee, Jae Kyung Sohng, Hei Chan Lee, Kwangkyoung Liou, Byung-Gee Kim

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

dTDP-L-rhamnose, an important precursor of O-antigen, was prepared on a large scale from dTMP by executing an one-pot reaction in which six enzymes are involved. Two enzymes, dTDP-4-keto-6-deoxy-D-glucose 3,5-epimerase and dTDP-4-keto-rhamnose reductase, responsible for the conversion of dTDP-4-keto-6-deoxy- D-glucose to dTDP-L-rhamnose, were isolated from their putative sequences in the genome of Mesorhizobium loti, functionally expressed in Escherichia coli, and their enzymatic activities were identified. The two enzymes were combined with an enzymatic process for dTDP-4- keto-6-deoxy-D-glucose involving TMP kinase, acetate kinase, dTDP-glucose synthase, and dTDP-glucose 4,6- dehydratase, which allowed us to achieve a preparative scale synthesis of dTDP-L-rhamnose using dTMP …
