Application of Measured Directivity Patterns to Acoustic Array Processing (2014)

The desire for hands-free telephony and immersive teleconferencing/telepresence systems has sparked much interest in signal processing for microphone and loudspeaker arrays. Many of the tools that are now commonplace in acoustic arrays have roots in entirely different fields; most Beamforming techniques stem from phased-array antenna technology and much of Fourier acoustics is borrowed from quantum theory, both emerging around the beginning of the 20th Century. While the impact of these tools is undeniable, many design procedures nevertheless make assumptions that are reasonable for the original scenarios but are not so valid in the acoustic case. For instance, transducers may be assumed to be omnidirectional, have a flat frequency response, or be matched in sensitivity. Ideally the design of processing algorithms should account for non-ideal behavior by using measured directivity and radiation patterns that can vary significantly in the real world. In this talk we investigate how practical measurements can be made, how array signal processing can benefit from this information in the acoustic Beamforming scenario, and other applications in the field of audio and acoustics.
Study to Compare the Efficacy of Three Oxytetracycline Regimens for the Treatment of Anaplasma Marginale Carrier Status in Beef Cattle (2004)

Anaplasmosis is a blood-borne disease of cattle and other ruminants caused by Anaplasma marginale. Animals recovering from clinical anaplasmosis and those treated with therapeutic doses of oxytetracycline remain persistently infected with microscopically undetectable levels of the organism. These animals serve as reservoirs of the disease which can be spread mechanically or through arthropod vectors. Tetracyclines are the only compounds approved for treatment of acute anaplasmosis infections in the United States; however no compounds are approved for eliminating the carrier state. This has contributed to the restricted movement of cattle from endemic areas of the US to anaplasmosis-free territories such as Canada. Anaplasmosis is estimated to cost the US cattle industry $100 million per year, with some estimating the cost of resticted trade to be near $300 million annually. The objective of this study was to compare the effects of three oxytetracycline treatment regimens on eliminating Anaplasma marginale infection from carrier beef steers.

The Static Electrification of Dust Particles on Dispersion into a Cloud (1950)

An extensive study of the charge and size distribution of particles from 0.5 to 30 microns radius in dust clouds of diverse exemplary types dispersed in air under a variety of conditions ranging from blowing with minimum of turbulence to conditions of violent and maximum impact with various types of surfaces was made using adaptations of the Hopper and Laby modification of the oil drop experiment. It was observed that all dusts, including homogeneous dusts with no impacts on solid surfaces, were charged. In homogeneous systems the charges of opposite sign were equal, no net charge resulting, the number of particles of similar size with opposite charges being about the same. The magnitude of charges increased somewhat less rapidly than the surface of the particle. There was no correlation between size and sign of charge. There is strong evidence that charging occurs on separation of the contacts between particles in the dispersion of the cloud. Humidity did not affect the charging. Studies of heterogeneous systems making contact with solid walls of different composition from the powder gave consistent asymmetry of charge of varying degrees depending on the proportion of particles striking the surfaces relative to those just separated.
Numerical simulation of a three-dimensional flame/shock wave interaction (1998)

A three-dimensional Navier-Stokes solver for chemically reacting flows is used to study the structure of a supersonic hydrogen-air flame stabilized in a Mach 2.4 rectangular cross-section wind tunnel. The numerical model uses a 9-species, 21-reaction hydrogen oxidation mechanism and employs Menter's hybrid κ-ω/κ-e turbulence model. An assumed probability density function is used to account for the effects of turbulent temperature fluctuations on the ensemble-averaged chemical reaction rates. Results are presented for a configuration studied at the University of Michigan in which the effects of wedge-generated shock waves on flame stability were determined. Computed pitot and static pressure profiles are compared with experimental measurements, and axial density gradient contour plots are compared with experimental schlieren photographs. The highly three-dimensional structure of the flame is described in detail, and stabilization mechanisms are discussed
High Temperature Protonic Conduction in Aragonite-Type NdBO3 (2004)

Electrical conduction in undoped and Ca-doped NdBO3 with the orthorhombic aragonite-type structure was investigated by using conductivity measurements under 0.4-5kPa of p(H2O) and 0.01-100kPa of p(O2) at 500-925°C. From humidity dependence and H/D isotope effect of the conductivity, it was found that NdBO3 became a protonic conductor under wet conditions by partially substituting Ca for Nd. The conductivities of 1mol%Ca-doped NdBO3 were 10-5.4-10-4.1 S⋅cm-1 under wet condition at 500-925°C. As temperature increased, electron holes became to contribute to the conduction, although protons were estimated as dominant charge carriers under the conditions employed. The p(H2O) and p(O2) dependence of the conductivity were discussed in terms of defect equilibrium. Conductivity behaviors as well as conductivity values of Ca-doped NdBO3 were rather similar to those of the Sr-doped LaBO3 with the same crystal structure.
Liikunta ja ruokavalio ovat metabolisen oireyhtymän (2001)

Metabolinen oireyhtyma on lansimaiseen elamantyyliin liittyva monisyinen riskitekijakasauma, jolle tunnusomaisia piirteita ovat insuliiniresistenssi/hyperinsulinemia ja vartalolihavuus. Usein todetaan glukoosi- ja lipidiaineenvaihdunnan hairioita ja tromboosialttiutta, ja oireyhtyma lisaa vaaraa sairastua tyypin 2 diabetekseen ja valtimokovettumatautiin. Oireyhtyman esiintyvyys riippuu lihavuuden yleisyydesta vaestossa. Keski-ikaisilla se on 7‐27 % aineiston mukaan. Metabolisen oireyhtyman perussyyt ovat osin tuntemattomat, mutta sille altistavat perinnolliset tekijat, sikiokautinen tai varhaislapsuuden ravitsemushairio, lihavuus ja liikunnan puute. Myos runsaasti kovaa rasvaa ja vahan kuitua sisaltava ruokavalio ja psykososiaaliset tekijat voivat altistaa oireyhtymalle. Terveellinen ruokavalio, laihdutus ja saannollinen liikunta muodostavat metabolisen oireyhtyman tehokkaan tasmahoidon, kunhan potilasohjaus on ammattimaista. Nykyaan perusterveydenhuollossa ei ole riittavia valmiuksia. Kansanelakelaitos voisi arvioida uudelleen ravitsemushoidon tukea.

Calorimetric determination of the electron-phonon mass enhancement of<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>α</mml:mi></mml:math>-uranium (1975)

A conduction-electron mass enhancement $\ensuremath{\lambda}$ for the 2-K superconducting $\ensuremath{\alpha}$ phase of uranium was obtained from a comparison of the linear coefficient of the electronic heat capacity at high temperature, ${\ensuremath{\gamma}}_{b}$, with that at low temperature, ${\ensuremath{\gamma}}_{0}$. A $\ensuremath{\lambda}$ of 0.9 \ifmmode\pm\else\textpm\fi{} 0.2 was found. The ${\ensuremath{\gamma}}_{0}$ value used was obtained in a high-pressure experiment reported in the literature. The ${\ensuremath{\gamma}}_{b}$ value was extracted from published heat-capacity measurements below 500 K by adjustment of the data to the volume of the low-temperature experiment, subtraction of an appropriate Debye function, correcting for anharmonicity, and graphically fitting the resultant electronic contribution. The uncertainty in $\ensuremath{\lambda}$ is dominated by the uncertainty in the characterization of the constant-volume lattice anharmonicity, which was estimated using Wallace's recent empirical correlation based on Gr\"uneisen constants. Using the observed magnitude of $\ensuremath{\lambda}$ and ${T}_{c}$, McMillan's equation for the superconducting transition temperature indicates that large Cooper-pair-weakening interactions are probably present in $\ensuremath{\alpha}$-uranium. It is known that the ${\ensuremath{\gamma}}_{0}$ value of the 2-K superconducting $\ensuremath{\alpha}$ phase of uranium is \ensuremath{\sim}30% higher than the ${\ensuremath{\gamma}}_{0}$ value of the lower-${T}_{c}$ single-crystal uranium at zero pressure. A combined analysis of the electronic heat capacity and magnetic susceptibility below room temperature indicates that the different values of ${\ensuremath{\gamma}}_{0}$ reflect not only changes in the unenhanced electronic density of states at the Fermi energy, but also substantial changes in $\ensuremath{\lambda}$. Furthermore, the low-pressure depression of ${T}_{c}$ relative to the $\ensuremath{\alpha}$-phase ${T}_{c}$ value of 2 K is in large part due to a depression in $\ensuremath{\lambda}$.
Peptide uptake by <i>Salmonella typhimurium</i> The periplasmic oligopeptide‐binding protein (1986)

The uptake of most peptides, including many peptide antibiotics, by the oligopeptide permeases of Escherichia coli and Salmonella typhimurium requires the function of a specific peptide-binding protein (the OppA protein) located within the periplasm. The OppA protein is the largest and most abundant periplasmic substrate-binding protein known and has an unusually broad substrate-binding specificity. The OppA protein has been purified to homogeneity and anti-OppA antibodies have been raised. The sequence of the OppA protein has been deduced from the nucleotide sequence of the oppA gene. This protein is unrelated to any other known periplasmic substrate-binding protein, either immunologically or in its amino acid sequence. The role of this protein in peptide transport is discussed.
Effects of changes in effective rail height on barrier performance. Volume 1, Research report (1987)

The objective of this project was to determine the critical rail mounting heights to prevent underride and override for traffic barriers. W-beam guardrails, which are the most commonly specified barrier in the U. S., were used to develop criteria for both this element and the thrie beam. The scope of the project included both computer simulation and full-scale crash tests. The test barriers were installed on level and sloping terrains. Most of the testing was accomplished using 4500-lb (2000-kg) and l800-lb (500-kg) vehicles. One test was conducted using a low front profile car impacting a cable guardrail system.\n

Design and control of energy efficient food drying processes with specific reference to quality; evaluation of physical and quality changes in foods during drying (1989)

The ultimate goal of the project is to develop procedures, techniques, data and other information that will aid in the design of cost effective and energy efficient drying processes that produce high quality foods. This objective has been sought by performing studies to determine the pertinent properties of food products, by developing models to describe the fundamental phenomena of food drying and by testing the models at laboratory scale. Finally, this information is used to develop recommendations and strategies for improved dryer design and control. This volume emphasizes a detailed literature review and several extensive experimental studies. Since the basic principle of food dehydration is the removal of water from food, the process of removing water causes quality changes which can be categorized as physical, chemical, and nutritional. These changes often have adverse effects on the quality of the resulting dehydrated food. In this work, the types of physical and chemical changes common in food drying and the important factors for them were reviewed. Pertinent kinetic models and kinetic data reported in literature were also collected and compiled as the results of review study. The overall objectives of this study were to identify major quality change in foods caused bymore » drying process and to get the knowledge of the relationship between the quality change and factors known to affect them. The quality parameters reviewed included: browning, lipid oxidation, color loss, shrinkage, solubility, texture, aroma and flavor, vitamin and protein loss and microbiological concerns. 54 refs., 74 figs., 49 tabs.« less
Spectroscopic characterization and evaluation of SiO{sub 2}-overcoated silver islands as a SERS substrate (1995)

Vacuum deposition of a 50-{Angstrom} layer of silver and a subsequent 50-{Angstrom} layer of SiO{sub 2} onto glass is shown to be a viable substrate for Surface-Enhanced Raman Spectroscopy (SERS) and a suitable model of silica surfaces. The model silica surface is characterized by SERS, Atomic Force Microscopy (AFM), and Auger Electron Spectroscopy (AES). SERS of pyridine adsorption onto the SiO{sub 2} overlayer was used to characterize differences between the silica and silver surfaces. Adsorption isotherm and kinetic data for surfactant adsorption at the silica/solution interface have been elucidated with SERS employing the SiO{sub 2}/Ag substrates. Surface roughness relative to the underlying silver-island film and general structure of the substrate was measured with contact mode AFM. AES was used to probe the silica surface for possible exposure of silver through pinholes in the silica overcoat; the {open_quotes}pinhole percentage{close_quotes} was determined to be {<=} 1%
Weighted range sensor matching algorithms for mobile robot displacement estimation (2003)

Introduces a "weighted" matching algorithm to estimate a robot's planar displacement by matching two-dimensional range scans. The influence of each scan point on the overall matching error is weighted according to its uncertainty. We develop uncertainty models that account for effects such as measurement noise, sensor incidence angle, and correspondence error. Based on models of expected sensor uncertainty, our algorithm computes the appropriate weighting for each measurement so as to optimally estimate the displacement between two consecutive poses. By explicitly modeling the various noise sources, we can also calculate the actual covariance of the displacement estimates instead of a statistical approximation of it. A realistic covariance estimate is necessary for further combining the pose displacement estimates with additional odometric and/or inertial measurements within a localization framework. Experiments using a Nomad 200 mobile robot and a Sick LMS-200 laser range finder illustrate that the method is more accurate than prior techniques.

Vertically Pluggable and Compact 10-Gb/s$\,\times\,$12-Channel Optical Modules With Anisotropic Conductive Film for Over 100-Gb/s Optical Interconnect Systems (2009)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> We have developed a vertically pluggable and compact 12-channel optical module for intercabinet and intracabinet optical interconnections. Error-free and over 10 Gb/s operation of the optical module with an electrical and optical connector have been demonstrated. The module is designed to be 10 mm in width, 10 mm in length, and 6 mm in thickness so that it can be placed around the central processing units. This compact optical module can be mounted on the inner board area. Further, this module is vertically pluggable in the <formula formulatype="inline"><tex Notation="TeX">${z}$</tex></formula>-direction, i.e., in a direction that is perpendicular to the board. Because of the vertical pluggability, the optical modules can be repaired much more easily. The optical connector used in the low-height module has 12 fine-drawn graded-index multimode fibers (MMFs). These fibers have a high relative refractive index difference (<formula formulatype="inline"><tex Notation="TeX">$\Delta$</tex></formula>) and are bent with a 2 mm radius of curvature. The electrical connector consists of an anisotropic conductive film that is sandwiched between an alumina substrate and a printed circuit board with a clamp spring. We have used the alumina substrate to mount the optical device and the driver integrated circuit, because of its high thermal conductivity. In order to reduce cost, we have not used either a microlens or a metal-coated mirror in the optical module. Furthermore, passive alignment between the MMFs and the optical device has been achieved using guide pins assembled in the alumina substrate. </para>
First Report of <i>Phakopsora pachyrhizi</i> Telia on Kudzu in the United States (2006)

Soybean rust caused by Phakopsora pachyrhizi H. Sydow & Sydow was first reported in the continental United States during 2004 (2). By 10 November 2005, the disease was confirmed in eight southern states (Florida, Georgia, Alabama, Mississippi, South Carolina, North Carolina, Louisiana, and Texas). Diagnoses have been based on visual observation of uredinia and urediniospores of the pathogen followed by polymerase chain reaction confirmation. On 10 November 2005, uredinia and telia were identified on leaves of kudzu (Pueraria lobata) in central Florida. Telia first were noted as dark brown-to-black flecks on the abaxial leaf surface intermingled with abundant tan-to-light brown uredinia. Of 200 leaves examined, 143 (72%) had telia. The number of telia ranged from a few (1/cm<sup>2</sup>) that were scattered to many (73/cm<sup>2</sup>). Telia were approximately the same diameter as uredinia, but were appressed to the leaf surface and pigmented. Twenty telia were excised from host tissue with the aid of a dissecting microscope and a 20 gauge hypodermic needle. Telia averaged 89 × 100 μm (n = 20, σ = 17 and 16 μm, respectively). Four telia were crushed and five teliospores from each averaged 4.3 × 8.3 μm (n = 20, σ = 0.5 and 0.9 μm, respectively). Pale yellowish brown-to-hyaline teliospores were similar in color to urediniospores. Observations matched descriptions by Ono et al. (1). To our knowledge, this is the first report of the telial stage of P. pachyrhizi in the United States. References: (1) Y. Ono et al. Mycol. Res. 96:825, 1992. (2) R. W. Schneider et al.
