The Effects Of A Variable Modulus Of Elasticity On Prestress Losses In Bridge Girders
(Civil & Environmental Engineering, 2011-10-11)
The purpose of this research is to evaluate a method proposed by Franz Dischinger (Dischinger, 1939) to consider the effects of a variable modulus of elasticity (MOE) of concrete over a period of time. Current guidelines ...
Convert UHF RFID Tag From Passive To Semi-passive Tag Using External Power Sources
(Electrical Engineering, 2011-03-03)
In this thesis, I present novel circuit designs that convert a passive radio frequency identification (RFID) tag into a semi-passive RFID tag. Passive RFID tags are relatively inexpensive to purchase and to integrate into ...
In Vivo Tracking Of Mesenchymal Stem Cell Recruitment To Tissue Scaffolds
(Biomedical Engineering, 2010-07-19)
The term "Stem cells" has been extensively used to describe precursor undifferentiated cells that have the capacity to self-renew and can also give rise to multiple tissue types. Many studies have been shown improved ...
Target Tracking With Lucas-kanade Optical Flow And Particle Filters Through Affine Transforms And Occlusion
(Computer Science & Engineering, 2011-03-03)
This paper investigates a hybrid approach derived from Lucas-Kanade optical flow tracking and particle filters that is capable of tracking objects through occlusion and affine transformations. This approach is inspired ...
A Highly Linear Voltage Controlled Oscillator With Low Power Dissipation
(Electrical Engineering, 2011-10-11)
A voltage controlled oscillator using 90 nm CMOS technology has been presented with the extremely low power dissipation of 1.35 mW and provides 1.45 mW (with use of buffers) output AC power. It has highly linear voltage ...
Nanoparticle Bridge DNA Biosensor
(Materials Science & Engineering, 2010-07-19)
A new DNA sensing method is demonstrated in which DNA hybridization events lead to the formation of nanoparticle satellites that bridge two electrodes and are detected electrically. The hybridization events are exclusively ...
Characteristics Of Fresh Municipal Solid Waste
(Civil & Environmental Engineering, 2010-07-19)
The characteristics of fresh municipal solid waste (MSW) are critical in planning, designing, operating or upgrading solid waste management systems. Physical composition, moisture content, compacted unit weight, permeability ...
The Translator's Assistant: A Multilingual Natural Language Generator Based On Linguistic Universals, Typologies, And Primitives
(Linguistics, 2011-07-14)
The Translator's Assistant (TTA) is a multilingual natural language generator (NLG) designed to produce initial drafts of translations of texts in a wide variety of target languages. The four primary components of every ...
Unsaturated Soil Behavior Under Large Deformations Using A Fully Servo/suction-controlled Ring Shear Apparatus
(Civil & Environmental Engineering, 2011-07-14)
In recent years, the key hypotheses of most elasto-plastic constitutive frameworks postulated for unsaturated soils have been validated via suction-controlled oedometer, triaxial, and direct shear testing. These techniques, ...
Effect Of Leachate Recirculation On Methane Generation Of A Bioreactor Landfill
(Civil & Environmental Engineering, 2010-11-01)
Municipal solid waste (MSW) disposal is of current concern due to the green-house effect and rising temperature all around the globe. Landfill gas is generated from aerobic & anaerobic biodegradation of organic materials ...
