Spectral Sensitivity, Spatial Resolution And Temporal Resolution And Their Implications For Conspecific Signalling In Cleaner Shrimp, Eleanor M. Caves, Tamara M. Frank, Sonke Johnsen

Marine & Environmental Sciences Faculty Articles

Cleaner shrimp (Decapoda) regularly interact with conspecifics and client reef fish, both of which appear colourful and finely patterned to human observers. However, whether cleaner shrimp can perceive the colour patterns of conspecifics and clients is unknown, because cleaner shrimp visual capabilities are unstudied. We quantified spectral sensitivity and temporal resolution using electroretinography (ERG), and spatial resolution using both morphological (inter-ommatidial angle) and behavioural (optomotor) methods in three cleaner shrimp species: Lysmata amboinensis,Ancylomenes pedersoni and Urocaridella antonbruunii. In all three species, we found strong evidence for only a single spectral sensitivity peak of (mean±s.e.m.) 518±5, 518±2 and …

Research Publications (2016 to 2020)

Leptospirosis is an emerging disease, especially in countries with a tropical climate such as Malaysia. A dramatic increase in the number of cases has been reported over the last decade; however, information on the epidemiological trends of this disease is lacking. The objective of this study is to provide an epidemiological description of human leptospirosis cases over a 9-year period (2004–2012) and disease relationship with meteorological, geographical, and demographical information. A retrospective study was undertaken to describe the patterns of human leptospirosis cases and their association with intrinsic (sex, age, and ethnicity) and extrinsic (location, rainfall, and temperature) factors.

Relativistic Backward Wave Oscillator With A Gaussian Radiation Pattern And Related Technologies, Ahmed Elfrgani

Electrical and Computer Engineering ETDs

Short pulse high power microwave (HPM) devices with Gaussian radiation pattern are attractive for many applications. The importance of the Gaussian microwave beam is that its maximum energy density is concentrated on axis. The purpose of this study is to use a backward wave oscillator (BWO), which is typically known to radiate in the TM01 mode, to produce an HPM Gaussian wave beam. A BWO generates an electromagnetic wave with negative group velocity where the wave is traveling in the direction opposite to the electron beam. Thus, to extract the microwave signal axially, a cavity resonator reflector or cutoff waveguide …

Direct Voltage Measurements Using Bulk Acoustic Waves In Linbo3, Nishant Patel

Electrical and Computer Engineering ETDs

Accurate (< 1%) direct measurement of high voltage pulse amplitudes above 10 kilovolts becomes challenging due to voltage breakdown limitations in materials, parasitic impedance effects that can distort the pulse shape, and pickup of extraneous signals resulting from electromagnetic interference effects. A piezoelectric crystal-based bulk acoustic wave sensor using lithium niobate (LiNbO3) that has applications to metrology, research, and power metering was developed to overcome these measurement issues with the factors of scalability, ease of use, and compactness in mind. A Y+36° cut LiNbO3crystal was coupled to two acoustic transducers, where direct current (DC) voltages ranging from 128—1100\u2009V were applied transversely to the crystal. An acoustic wave was used to interrogate the crystal before, during, and after voltage application. Both single and multiple pass measurements were performed and compared to linear piezoelectric theory. A comparison study between Y+36° and 0° X-cut LiNbO3 was performed to evaluate the influence of crystal cut on acoustic propagation. The study was extended to applying alternating current (AC), and pulsed voltages. The measured DC data was compared to a 1-D impedance matrix model that was based on a three port circuit with voltage-induced strain effects inputted as a model parameter. An uncertainty budget was carried out for both crystal cuts and compared. Environmental effects such as pressure and temperature were also measured to determine their influence on the sensor under ambient conditions. Published literature regarding material constants, such as elastic constants and piezoelectric constants, for LiNbO3 do not account for the influence of an electric field. In light of this, measurements of the acoustic velocities and material constants under the presence of a DC electric field were performed up to 896 V. This information was used to develop an uncertainty analysis for the determination of stress-charge form piezoelectric constants e15 and e22. All measured and calculated values were input into a Monte Carlo simulation to determine the error of the strain-charge form piezoelectric constants, dij, and how these new values can be used to predict the voltage sensor response.

Operations Rescheduling Strategies, Policies, And Methods: A Philosophic Approach, Ghassan Kasim Dawood Al-Lami, Maha A. Hammoud Al-Rawi

Journal of Economics and Administrative Sciences

When scheduling rules become incapable to tackle the presence of a variety of unexpected disruptions frequently occurred in manufacturing systems, it is necessary to develop a reactive schedule which can absorb the effects of such disruptions. Such responding requires efficient strategies, policies, and methods to controlling production & maintaining high shop performance. This can be achieved through rescheduling task which defined as an essential operating function to efficiently tackle and response to uncertainties and unexpected events. The framework proposed in this study consists of rescheduling approaches, strategies, policies, and techniques, which represents a guideline for most manufacturing companies operating in …

Spanning Eulerian Subgraphs And Catlin’S Reduced Graphs, Wei-Guo Chen, Zhi-Hong Chen

Scholarship and Professional Work - LAS

A graph G is collapsible if for every even subset R ⊆ V (G), there is a spanning connected subgraph H_R of G whose set of odd degree vertices is R. A graph is reduced if it has no nontrivial collapsible subgraphs. Catlin [4] showed that the existence of spanning Eulerian subgraphs in a graph G can be determined by the reduced graph obtained from G by contracting all the collapsible subgraphs of G. In this paper, we present a result on 3-edge-connected reduced graphs of small orders. Then, we prove that a 3-edge-connected graph G of order n …

A Disk-Based Dynamical Constraint On The Mass Of The Young Binary Dq Tau, I. Czekala, S. M. Andrews, G. Torres, Eric L.N. Jensen, K. G. Stassun, D. J. Wilner, D. W. Latham

Physics & Astronomy Faculty Works

We present new Atacama Large Millimeter/Submillimeter Array (ALMA) observations of CO J = 2-1 line emission from the DQ Tau circumbinary disk. These data are used to tomographically reconstruct the Keplerian disk velocity field in a forward-modeling inference framework, and thereby provide a dynamical constraint on the mass of the DQ Tau binary of {M}_*={1.27}_-0.27^+0.46 {M}_☉ . Those results are compared with an updated and improved orbital solution for this double-lined system based on long-term monitoring of its stellar radial velocities. Both of these independent dynamical constraints on the binary mass are in excellent agreement: …

The Learning Needs Of Community College Emerging Scholars, Janet K. Walsh

Dissertations

The community college mission has always centered on providing higher education opportunities for all people (American Association of Community Colleges [AACC], 2015a; Bailey, Jaggars, & Jenkins, 2015; Dassance, 2011; Dotzler, 2003; Greenburg, 2008; Schuh, Jones, Harper, & Associates, 2011). However, many students who enrolled at the community college level were not college ready and often required developmental coursework to help bridge the knowledge gap prior to taking college level courses. Unfortunately, those students were unlikely to obtain higher education credentials (Bailey et al., 2015; Carnegie Foundation, 2014). On the other hand, the researcher observed a relatively small number of students …
