Regulation in Switched Bimodal Linear Systems
… in intermittent contact between the two and a bimodal system behavior, this thesis studies the output regulation problem in switched bimodal linear systems against known and unknown exogenous input signals. The regulation problems in bimodal systems presented in this thesis are solved within …

High density bimodal parts by three dimensional printing
… into a large powder bed to create a dense bimodal compact was investigated. Experiments performed demonstrated that a uniform, defect free microstructure could be obtained by appropriately selecting 3DP process parameters. By spreading 4 mil layers, and double printing, sample coupons with …

TACTILE AND MULTISPECTRAL BIMODAL IMAGING FOR BREAST CANCER RISK ASSESSMENT
… non-invasive imaging modalities. The proposed bimodal imaging system has tactile and multispectral imaging capabilities. Tactile imaging modality characterizes tumors by esti-mating their depth, size, and stiffness, along with the Tactile Index. Multispectral imaging modality identifies breast …

How Teachers Build Relationships with Students in a Bimodal Environment
… were encouraged or required to teach on a bimodal platform, forcing them to create lessons, deliver lessons, and build student relationships in a way they had not experienced before. The purpose of my study was to investigate the strategies teachers were using to build relationships with …

Improving the safety and efficacy of bimodal electric tissue ablation.
Introduction: Bimodal electric tissue ablation (BETA) is a new method of ablation, which combines the process of electrolysis with radiofrequency ablation (RFA) to increase the size of tissue ablations. The cathode of the electrolytic circuit is connected to the radiofrequency (RF) electrode to …

Synthesis and Design of a Bimodal Rotary Series Elastic Actuator
… elastic actuator (RSEA) with a two-mode, or bimodal, elastic element was designed and tested. This device was developed to eliminate the compromise between human safety and robot performance. Rigid actuators can be dangerous to humans within a robot's workspace due to impacts or pinning …

Design of a Bimodal Chemical-Electrospray Propulsion System using Ionic Liquid Monopropellants
… design that takes advantage of this to create a bimodal propulsion system with access to both chemical monopropellant and electrospray propulsion. The proposed system builds upon existing technology, commercially available green monopropellant thrusters and the MIT iEPS electrospray thrusters, …

TOWARD ENHANCED BIMODAL SENSING: TIO₂-COATED METALLIC NANOSTRUCTURES FOR ELECTROCHEMICAL ANDPHOTOELECTROCHEMICAL DETECTION
… (PEC). This dual functionality was defined as bimodality. Based on this bimodal approach, a new device was developed combining TiO2 with silver nanostructures. The aim was to evaluate the effect of replacing gold with silver and to verify the feasibility of bimodality in a context closer to …

Development of bimodal grain structures and their effect on toughness in HSLA steel
To understand the formation of bimodal ferrite grain structures (i.e. mixed coarse + fine grain sizes) in TMCR HSLA steel plates, as-continuously cast HSLA steel slabs with varying microalloying additions (Ti, Nb and V) were reheated to temperatures in the range 1000-1300 °C and deformed at 1110 °C …

Investigation of iron isotope variability in the bimodal Aztec Wash Pluton, Eldorado Mountains, Nevada
… the Miocene-aged Aztec Wash Pluton (AW). AW is a bimodal, reversely zoned pluton, consisting of an outer “rim” of granite (the granite zone) underlain by the heterogeneous zone, which contains co-existing mafic, felsic and intermediate rocks. Rotation of the intrusion during Basin and Range …

Block copolymer-templated iron oxide nanoparticles for bimodal growth of multi-walled carbon nanotubes
Since their discovery carbon nanotubes (CNTs) have sparked great interest due to their exceptional mechanical, electrical, and thermal properties. These properties make carbon nanotubes desirable for numerous applications including: nanoelectronics, high-strength composites, energy storage, …

Young infants' attention and emotional responses to dynamic and static bimodal displays of affect
This experiment was designed to elucidate the function of adult facial and vocal behavior for infant perception and expression of affect. Nine infants were studied longitudinally at 2 months and at 3 1/2 months using a dynamic visual display that consisted of a videotape of a woman moving her face …

On a Bimodal Distribution of Grain Size in Mechanically Alloyed Bulk Tungsten Heavy Alloys
… alloys with 2, 4 and 6 wt.% Ni. Evidence of a bimodal grain size distribution was seen in X-ray diffractograms of sintered samples and confirmed by scanning electron microscopy. Grain sizes in the small-grained regions ranged from 200–600 nm; those in the large-grained regions ranged from 1–2 …

Variation in the Bimodal Precipitation Regime of Southern Nevada, USA Measured in Tree-Ring Isotopes
… Mexico. Inter-annual variation of the NAMS bimodal precipitation regime is more predictable in its core region of northwestern Mexico, Arizona, and New Mexico, USA than at its northwest boundary. The NAMS onset and strength is projected to shift during the 21st century because of climate …

Evidence for rapid epithermal mineralization and coeval bimodal volcanism, Bruner Au-Ag property, NV USA
The character of Au-Ag mineralization and volcanic/hydrothermal relationships at the underexplored Miocene-age Bruner low-sulfidation epithermal Au-Ag deposit are elucidated using field and laboratory studies. Bruner is located in central Nevada within the Great Basin extensional province, near …

The distribution of wave heights and periods for seas with unimodal and bimodal power density spectra
… as unimodal and spectra with two peaks as bimodal. Seas are further classified by spectral width, a function of the three lowest spectral moments. The joint distributions of wave heights and periods from seas with narrow spectral widths take the general shape predicted by narrow-band theory …

The Rheology and Microstructure of Dense Bimodal Mixtures of Colloidal Particles With Long-Range, Soft Interactions
The rheology of the mixtures is remarkably similar to the monodisperse suspensions for most applied shear stresses. Yield stresses and the general flow curves for all mixtures studied followed the same scaling on the elastic modulus as the monodisperse suspensions. The mixtures display substantial …
