Creators: name: Paulino, Farlin
Publisher: name: Utah State University
Year: 2018

description: This portfolio is a compilation of the author’s beliefs in regard to effectively teaching English as a Foreign Language and Spanish as a Second language. This work was completed for the Master of Second Language Teaching (MSLT) program at Utah State University. All the work compiled in this portfolio centers on the teaching philosophy statement, which contains what the author believes to be the most important aspects of teaching a second language. In the first section of the portfolio, the author presents the experiences that made him pursue the profession of teaching languages, his personal philosophy of teaching shaped by what he has learned in the MSLT program, and how he believes are the roles of teachers in a classroom.
The second section of the portfolio contains three papers that were written during the MSLT program as term papers for courses. First, the language paper describes the current situation of Latin American countries’ education systems, how Dual
Language Immersion (DLI) program works, and how it could be implemented in their context. Second, the culture paper explores the importance of refusal in transcultural interactions. Third, the literary paper focuses on co-teaching in a Spanish as a second language classroom. Finally, the annotated bibliography contains three sections, each addressing topics that record the author’s learning in the MSLT program. The first topic is about the author’s acknowledgement of the Communicative Language Teaching Methodology. In addition, the second topic explores the phenomenon of Dual Language Immersion (DLI) in the second language classroom. Lastly, the third topic explores the use of social networks in the classroom.

description: We present a new suite of photometric and spectroscopic data for the faint Bootes II dwarf spheroidal galaxy candidate. Our deep photometry, obtained with the INT/WFC, suggests a distance of 46 kpc and a small half-light radius of 4.0 arcmin (56 pc), consistent with previous estimates. Follow-up spectroscopy obtained with the Gemini/GMOS instrument yielded radial velocities and metallicities. While the majority of our targets covers a broad range in velocities and metallicities, we find five stars which share very similar velocities and metallicities and which are all compatible with the colors and magnitudes of the galaxy's likely red giant branch. We interpret these as a spectroscopic detection of the Bootes II system. These stars have a mean velocity of -117 km/s, a velocity dispersion of (10.5+-7.4) km/s and a mean [Fe/H] of -1.79 dex, with a dispersion of 0.14 dex. At this metallicity, Boo II is not consistent with the stellar-mass-metallicity relation for the more luminous dwarf galaxies. Coupled with our distance estimate, its high negative systemic velocity rules out any physical connection with its projected neighbor, the Bootes I dwarf spheroidal, which has a velocity of ~+100 km/s. The velocity and distance of Bootes II coincide with those of the leading arm of Sagittarius, which passes through this region of the sky, so that it is possible that Bootes II may be a stellar system associated with the Sagittarius stream. Finally, we note that the properties of Bootes II are consistent with being the surviving remnant of a previously larger and more luminous dSph galaxy.

title: A Framework for Assessing Natural Lands and Finding Common Ground in the Bear River Range
Creators: name: McComb, Scott
Publisher: name: Utah State University
Year: 2018

description: Forests, wetlands, grasslands, lakes and deserts make up the natural lands that humans and nature rely on. In the Bear River Range, these lands are becoming smaller and more disconnected due to residential and commercial development, agriculture, energy production and transportation corridors. In addition, natural lands are owned and managed by a variety of groups representing different values, priorities and traditions. For large-scale conservation to be successful, it needs to incorporate multiple priorities. The purpose of this study was to provide a process for identifying the remaining network of natural lands within the Bear River Range that indicate high ecological value and to identify natural lands within the network that multiple stakeholders agree are important for conserving. Using the green infrastructure and bioregional planning processes, three stakeholders groups—planners, ranchers and environmentalists—were interviewed to identify and assess the landscape based on their group’s priorities. Geospatial modeling was then used to develop three stakeholder green infrastructure networks and to identify areas of consensus among the groups. This process provided a method for identified regionally important networks of natural lands for each stakeholder group and areas of consensus between the groups.
title: Carboxylases Involved in Microbial Acetone and Acetophenone Metabolism
Creators: name: Mashruwala, Ameya
Publisher: name: Utah State University
Year: 2010

description: A number of bacteria are capable of growth with acetone and acetophenone as their sole sources of carbon and/or energy. The pathways and enzymes involved in the transformation of these molecules into useable carbon and energy are unique. Among these are two novel enzymes, acetone carboxylase and acetophenone carboxylase, which represent a fundamentally novel classes of carboxylases.
The initial step in acetone metabolism, in X. autotrophicus st Py2, R. capsulatus st B10 and R. rhodochrous, is the thermodynamically unfavorable reaction to yield acetoacetate. This step is catalyzed by the enzyme acetone carboxylase and is coupled with the unprecedented, concomitant hydrolysis of two phosphoanhydride bonds of ATP. This enzyme also requires two tightly bound Mn2+ ions, among other co-factors, for catalytic activity.
In a similar, albeit distinct manner, acetophenone carboxylase catalyzes the carboxylation of acetophenone to benzoylacetate. Reminiscent of acetone carboxylase, carboxylation activity in this enzyme is dependent on the hydrolysis of ATP to ADP and inorganic phosphate. Catalytic activity is also dependent on Zn2+ and either of Mn2+ or Mg2+ as co-factors. Additionally, similar to acetone carboxylase, acetophenone carboxylase shows uncoupled ATPase activity with either bicarbonate or acetophenone in the absence of a second substrate. This indicates that both substrates may be phosphorylated.
The studies on acetone and acetophenone carboxylase have expanded our knowledge on the novel mechanisms and cofactors involved in the metabolism of toxic, reactive, xenobiotic molecules such as acetone and acetophenone. Further, as in the case of acetone carboxylase, homologs of these enzymes are found in higher organisms such as mammals. The biochemical and mechanistic properties of these enzymes may be relevant to the modes of action of these homologs. In this report, using the work currently accomplished on these enzymes, and by discussing their salient features, an effort has been made to provide a detailed insight into these enzymes.

description: We report the XMM-Newton/EPIC detection in 2008 March of a luminous (L_X ~ 10^32-33 erg/s), variable X-ray source in the vicinity (within ~6") of the enigmatic star V838 Mon, which underwent a spectacular outburst in early 2002. Spectral modeling of the XMM-Newton X-ray source indicates the presence of two plasma components with characteristic temperatures of TX ~ 2x10^6K and ~1.5x10^7K, attenuated by an absorbing column (N_H ~ 4 x 10^21cm^-2) that is consistent with the visual extinction measured toward V838 Mon (A_V ~ 2). No such luminous source was detected in the immediate vicinity of V838 Mon in Chandra/ACIS-S observations obtained about one year after outburst or, most recently, in 2010 January. The two XMM source spectral components appear to be marginally spatially resolved, with the spatial centroid of the hard component lying closer to (within ~2" of) the position of V838 Mon than the broad-band source or the soft source component; however, if there are two sources at or near V838 Mon, the Chandra nondetections would imply that both of them are variable. An alternative is that there is a single variable source, and that the apparent spatial separation may actually be due to photon-counting statistics or is perhaps instrumental in origin. We consider constraints placed by the X-ray detection and nondetections on a stellar merger model for the 2002 V838 Mon outburst, in which the spun-up merger product drives a powerful magnetic dynamo. Alternatively, the transient behavior of the X-ray source could indicate that the X-rays arose as a consequence of an interaction between V838 Mon's ejecta and its early-type (B3 V) companion.

title: Commuter Rail and the Landscape: Alternative Futures for Planning in Southeastern Box Elder County
Creators: name: Gottfredson, C. Michael
Publisher: name: Utah State University
Year: 2018

description: This thesis analyzes the impact the FrontRunner commuter-rail service would have on Southeastern Box Elder County, Utah, using both anticipated future and alternative future scenarios created in a geographic information system (GIS). These alternative future scenarios include having the FrontRunner developed at anticipated stops and a transit-oriented development (TOD) scenario. Using techniques and methods developed by scholars in the bioregional planning field, these alternative future scenarios were compared against impact-data models addressing residential land-use suitability and landscape risk.
Outcomes: from this analysis, the TOD alternative future scenario had the least impact on landscape risk impact-data model. The TOD model is based on short trips between stops within the region, and takes advantage of a diesel car driven train, rather than the engine driven train that is the FrontRunner. Other alternative future models should be developed and tested, including a bus-rapid transit alternative, and scenarios taking into account connections to Cache Valley, Utah. A community survey for development preferences would be beneficial, along with an official rail corridor identified.
Application: working with regional partners, such as the Bear River Association of Governments, planners and local officials can use the approach of this thesis to alter or create new alternative futures as they plan for the future of the region.

description: We study the phase equilibria of a fluid confined in an open capillary slit formed when a wall of finite length $H$ is brought a distance $L$ away from a second macroscopic surface. This system shows rich phase equilibria arising from the competition between two different types of capillary condensation, corner filling and meniscus depinning transitions depending on the value of the aspect ratio $a=L/H$. For long capillaries, with $a<2/π$, the condensation is of type I involving menisci which are pinned at the top edges at the ends of the capillary characterized by an edge contact angle. For intermediate capillaries, with $2/π1$, condensation is always of type II. In all regimes, capillary condensation is completely suppressed for sufficiently large contact angles. We show that there is an additional continuous phase transition in the condensed liquid-like phase, associated with the depinning of each meniscus as they round the upper open edges of the slit. Finite-size scaling predictions are developed for these transitions and phase boundaries which connect with the fluctuation theories of wetting and filling transitions. We test several of our predictions using a fully microscopic Density Functional Theory which allows us to study the two types of capillary condensation and its suppression at the molecular level.

description: A low frequency stochastic background of gravitational waves may be detected by pulsar timing experiments in the next five to ten years. Using methods developed to analyze interferometric gravitational wave data, in this paper we lay out the optimal techniques to detect a background of gravitational waves using a pulsar timing array. We show that for pulsar distances and gravitational wave frequencies typical of pulsar timing experiments, neglecting the effect of the metric perturbation at the pulsar does not result in a significant deviation from optimality. We discuss methods for setting upper limits using the optimal statistic, show how to construct skymaps using the pulsar timing array, and consider several issues associated with realistic analysis of pulsar timing data.

description: Corporate financial policy and the value of cash by Michael Faulkender and Rong Wang (2006) examined the cross sectional variation in the marginal value of corporate cash holdings that arises from differences in the corporate financial policy. The main findings were that the marginal value of cash declines with large cash holdings,higher leverage, and better access to capital market. The goal of this paper is to replicate and extend Faulkender & Wang's (2006) work to test whether their assumptions and results are still valid.
title: Aldol Reactions: E-Enolates and Anti-Selectivity
Creators: name: Anderson, Matthew Grant
Publisher: name: Utah State University
Year: 2005

description: A common structural motif in complicated natural product molecules is an alkyl group at an alpha position to a carbonyl and an alcohol at the beta position anti to each other. This arrangement occurs in bioactive molecules that are important for medical research such as spongistatin A at the C15-C16 position and in (-)-baconipyrone C at C12-C13. Bioactive molecules such as these generally occur in such a low concentration in the organism in which they originate that deriving them from the natural source for research is not practical so efficient syntheses are sought. Reactions that produce 1,2 syn aldol products have been perfected under most circumstances, but methods to produce 1,2 anti aldol products without bulky alkyl groups on the enolizable compound still need to be perfected. In the case of 3-pentanone under conditions of E-enolization the yield is only approximately 70:30 E: Z. Anti aldol reactions generally result from E-enolates but in the case of the enolate of 3-pentanone without large alkyl groups to enforce a particular geometry in the pericyclic transition state between the enolate and carbonyl compound the yield of 70:30 E:Z goes down to 64:36 anti:syn. Quoting Erick M. Carrera "additions that produce anti substituted aldol adducts remain elusive and intractable". Since the best yields of E-enolates and anti-aldol reactions rely on the short Lewis Acid-oxygen bond length to maximize steric interactions in the transition states perhaps different Lewis Acids can be developed that have shorter LA-oxygen bond lengths.

description: We show that the Truncated Wigner Approximation developed in the flat phase-space is mapped into a Lindblad-type evolution with an indefinite metric in the space of linear operators. As a result, the classically evolved Wigner function corresponds to a non-positive operator $\hat{R}(t)$, which does not describe a physical state. The rate of appearance of negative eigenvalues of $\hat{R}(t)$ can be efficiently estimated. The short-time dynamics of the Kerr and second harmonic generation Hamiltonains are discussed.

description: It has recently become possible to encode the quantum state of superconducting qubits and the position of nanomechanical oscillators into the states of microwave fields. However, to make an ideal measurement of the state of a qubit, or to detect the position of a mechanical oscillator with quantum-limited sensitivity requires an amplifier that adds no noise. If an amplifier adds less than half a quantum of noise, it can also squeeze the quantum noise of the electromagnetic vacuum. Highly squeezed states of the vacuum serve as an important quantum information resource. They can be used to generate entanglement or to realize back-action-evading measurements of position. Here we introduce a general purpose parametric device, which operates in a frequency band between 4 and 8 GHz. It is a subquantum-limited microwave amplifier, it amplifies quantum noise above the added noise of commercial amplifiers, and it squeezes quantum fluctuations by 10 dB.

title: Analysis of the Parkway Drive Landslide, North Salt Lake, UT
Creators: name: Hill, Brianna V.
Publisher: name: Utah State University
Year: 2018

description: On August 5th, 2014, a hillside failed behind a North Salt Lake City, UT neighborhood threatening several homes. Aerial Photography, Digital Elevation Models (DEM), geochemistry, rain gage and seismic data were used to test the influence of contributing factors in this landslide failure. Aerial photographs available from 1993 to present were examined for signs of tension cracks suggesting impending ground motion, as well as documentation of human modification along the hillslope. Repeat DEM analysis of elevation and slope of the hillside before and after the slide were examined to characterize the pre-failure hillslope and subsequent landslide. Geochemical analyses were run on samples of the Tertiary Norwood Tuff within and outside of the landslide boundaries. Precipitation and seismicity data were collected and compiled to identify if they played a role in initiating the landslide.
Analyses indicate that the hillslope was previously part of a gravel pit in the 1990s, which was reclaimed in the early 2000s. Tension cracks began to appear by 2002, indicating downslope movement of unconsolidated material. DEM analysis reveals that the hillside was not at a critical angle for failure, suggesting that the linear, graded hillslope was stable prior to the landslide release. Geochemical analysis of Norwood Tuff indicated it is clay-rich, containing montmorillonite, an expandable clay mineral. Two severe rain storms occurred within six days of the slide, providing the fluid for saturation of the montmorillonite clays in the altered Norwood Tuff underlying the landslide. No notable seismic events occurred leading up to the slope failure.
After the landslide event, the scarp and toe of the slide became over-steepened. The toe is not stable and continued movement is expected and has been observed. The driving forces for this slide included human modification to the slope both during gravel pit operation and post reclamation construction that under-cut the toe of the hillslope and changed local hydrology of the area by decreasing infiltration above the slope. This was compounded by a large precipitation event that saturated the clay-rich material, which was the specific trigger for this landslide event.

description: The random-dimer model is probably the most popular model for a one-dimensional disordered system where correlations are responsible for delocalization of the wave functions. This is the primary model used to justify the insulator-metal transition in conducting polymers and in DNA. However, for such systems, the localization-delocalization regimes have only been observed by deeply modifying the system itself, including the correlation function of the disordered potential. In this article, we propose to use an ultracold atomic mixture to cross the transition simply by externally tuning the interspecies interactions, and without modifying the impurity correlations.

title: Validation of 16 Degree Arced Labyrinth Weir Coefficients
Creators: name: Montgomery, Megan Gordon
Publisher: name: Utah State University
Year: 2018

description: Labyrinth weirs are frequently used to control flow in spillways. Arced labyrinth weirs have been developed and researched in an effort to pass additional flow. Arced labyrinth weirs are more efficient than labyrinth weirs due to their increased length and improved approach flow conditions. In the past research has been done to develop discharge coefficients, Cd, values for arced labyrinth weirs with varying sidewalls angles (a=6°, 12°, and 20°). The Cd data that has been developed can only be used for those specific geometries tested. The purpose of this study was to develop Cd data for an arced labyrinth weir with a sidewall angle of 16 degrees. Baseline Cd values for a 16-degree arced labyrinth weir with a cycle arc angle of 10 degrees were developed. However, due to uncertainties in the data, further research should be done before these Cd values are used in design.

description: Air travel has long been an established way of life for millions around the world, but innovation continues to push the boundaries of what is possible in the skies. While aviation has made it easy to travel long distances, the need to lower emissions from flights is pressing. The European Commission has described aviation as “one of the fastest-growing sources of greenhouse gas emissions.”
Airplanes release around 500 million tons of carbon dioxide into the atmosphere each year, representing a significant contribution to global warming. The very concept of a fossil-fuel-powered airplane needs to evolve to fully mitigate the impacts on the environment and prevent the worst effects of climate change. Electric flight replaces petrochemical consumption with a cleaner, battery-powered electricity.
The problem is, batteries simply do not offer power-to-weight ratio or cost needed to be feasible and will not for some time. The technological advancements that allowed Tesla to squeeze 335 miles from the Model S and Chevrolet to get 200 out of a Bolt are not enough to power anything more than the smallest aircraft for the shortest distance.
For an electric flight to really take off and become mainstream in both commercial and recreational markets, it needs better batteries. Other industries have replaced traditional lead-acid batteries with lithium-ion batteries, which now power most of our laptops, phones, and electric cars. But to be aviation compatible, the next generation of batteries needs to deliver a whopping amount of power while being simultaneously smaller, safer, and lighter than lithium-ion ones.

title: Design Survey of Laminated Composite I-Beam
Creators: name: Saha, Mrinmoy
Publisher: name: Utah State University
Year: 2018

description: Composite I-beams are popular for high-strength low-weight applications. Learning the macro-mechanics and designing the composite I-beam properly are necessary. In this report, a design overview of the composite I-beam is discussed which is based on classical lamination theory where it includes the homogenization approach, the plane stress assumption and the Kirchhoff hypothesis. Using these assumptions, a method was developed to come up with the effective material properties of a beam. Formulas to calculate maximum deflection and maximum bending stress and shear stress and the stress concentration at the connection of web-flange are discussed which describe ways for designing and manufacturing the I-beam.
Ideas for manufacturing I-beams are based on unidirectional fibers. Critical design considerations are discussed. The design considerations for stacking sequences, cross section, length of the beam, failure, buckling are discussed to give an insight to achieve intended I-beam design goals more effectively. For stacking sequences, it is found that the sequencing of the layers depends on configuration and loads applied on the beam. To counter shear, 45° layers are needed and to counter tension and compression, cross-ply are iv best. Minimizing cross-section while having more web height compared to flange width will strengthen the beam. Finally, some recommendations are made for future directions from this project.

We introduce the Killing supervector ξ^{A I} with the adjoint index I for a non-Abelian gauge group H. This formulation is applicable to the compactification of supermembrane from eleven dimensions into D dimensions, such as H = SO(11-D) for the compactification M_{11} \to S^{11-D} \times M_D (1\le D \le 9).

title: Opportunities and Challenges Involved with a Large-Scale Private Enterprise Focused on Improving Food Security in Semi-Arid Regions of Ethiopia
Creators: name: Richards, Anthony
Publisher: name: Utah State University
Year: 2018

description: In 2009, Morrell Agro Industries (MAI) was formed in Ethiopia with the mission to end famine in the country through growing imported dryland wheat varieties from the western United States. MAI entered into a lease agreement with the Ethiopian government for 25,000 ha of land in semi-arid brushland in the Oromia region. The Beltu farm was established at the location for seed multiplication and demonstration of the dryland initiative concept. From the first harvest in July of 2010 several challenges arose that prevented the success of the dryland seed initiative. From high intensity short duration rainfall events on Vertisol soils, to local violence and government corruption. On-farm research was conducted to understand issues causing poor crop performance. Test results showed water availability to be the most limiting factor for crop yields. Poor crop performance, coupled with unexpected government bureaucracy and the harsh business environment of Ethiopia led to the Beltu farm being abandoned by 2013 before research could be completed. This report examines the challenges and opportunities of socially aware entrepreneurship in developing countries.

name: Okada, Nobuchika

Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We consider extensions of the next-to-minimal supersymmetric model (NMSSM) in which the observed neutrino masses are described in terms of effective dimension six (or seven) rather than dimension five operators. All such operators respect the discrete symmetries of the model. The new particles associated with the double (or triple) seesaw mechanism can have sizable couplings to the known leptons, even with a TeV seesaw scale. In the latter case some of these new short-lived particles could be produced and detected at the LHC.

The universe is accelerating. Do we need a new mass scale?

description: We try to address quantitatively the question whether a new mass is needed to fit current supernovae data. For this purpose, we consider an infra-red modification of gravity that does not contain any new mass scale but systematic subleading corrections proportional to the curvature. The modifications are of the same type as the one recently derived by enforcing the "Ultra Strong Equivalence Principle" (USEP) upon a Friedmann-Lemaitre-Robertson-Walker universe in the presence of a scalar field. The distance between two comoving observers is altered by these corrections and the observations at high redshift affected at any time during the cosmic evolution. While the specific values of the parameters predicted by USEP are ruled out, there are regions of parameter space that fit SnIa data very well. This allows an interesting possibility to explain the apparent cosmic acceleration today without introducing either a dark energy component or a new mass scale.

Emission and absorption of photons and the black-body spectra in Lorentz-odd Electrodynamics

description: We study a number of issues related to the emission and absorption radiation by non-relativistic electrons within the framework of a Lorentz-breaking electrodynamics in (3+1) dimensions. Our main results concern how Planck-like spectrum law is sensitive to terms that violate Lorentz symmetry. We have realized that Planck law acquires extra terms proportional to the violating parameters: for the CPT-odd model, the leading extra terms appear to be linear or quadratic in these violating parameters according to the background vector is parallel or perpendicular to the photon wave-vector. In the CPT-even case a linear `correction' shows up. Among other possible ways to probe for these violations, by means of the present results, we may quote the direct observation of the extra contributions or an unbalancing in the mean occupation number of photon modes in a given thermal bath.

description: (Shortened) Luminous blue variable stars (LBVs) form dust as a result of episodic, violent mass loss. To investigate their contribution as dust producers in the Magellanic Clouds, we analyse 31 LBVs from a recent census. We built a maximally complete multi-wavelength dataset of these sources from archival data from near-IR to millimetre wavelengths. We review the LBV classification on the basis of the IR SED. To derive characteristic dust parameters, we fitted the photometry resulting from a stacking analysis. For comparison we also stacked the images of low- and intermediate-mass evolved stars in the LMC. We find four classes of sources: 1) LBVs showing mid-IR dust emission plus near-IR free-free emission from an ionised stellar wind (Class 1a) or only mid-IR dust emission (Class 1b); 2) LBVs with a near-IR excess due to free-free emission only (Class 2); 3) objects with an sgB[e] classification; and 4) objects with no detected stellar winds and no circumstellar matter in their SEDs. From the stacking analysis of the 18 Class 1 and 2 objects in the LMC, we derived an integrated dust mass of $0.11^{+0.06}_{-0.03} M_\odot$. This is two orders of magnitude larger than the value inferred from stacking 1342 extreme-AGB stars. The dust mass of individual LBVs does not correlate with the stellar parameters, possibly suggesting that the dust production mechanism is independent of the initial stellar mass or that the stars have different evolutionary histories. The total dust yield from LBVs over the age of the LMC is $\sim 10^4-10^5 M_\odot$. LBVs are potentially the second most important source of dust in normal galaxies. The role of dust destruction in LBV nebulae by a possible subsequent SN blast wave has yet to be determined. Recent theoretical developments in the field of dust processing by SN shocks highlight the potential survival of dust from the pre-existing circumstellar nebula.

Analysis of waterhammer effect on speed change and governing stability of hydraulic turbines
Creators: name: El-Fitiany, Farouk Abdalla
Publisher: name: University of British Columbia
Year: 2010

description: A linearized mathematical model for the analysis of turbine speed governing problem is presented. This model includes the elasticity effects of both water and penstock walls, the effects of turbine characteristic slopes, and the linearized equation of a proportional-integral hydraulic governor. The procedure can be extended to a governor with a derivative term as well. Exact, travelling-wave solutions for the different possible cases are derived and presented in simple forms. Taylor's expansion formulas which offer a more efficient alternative for numerical evaluation of the speed are also derived. Solutions in both cases take into consideration penstock friction losses in a linearized form, as well as permanent speed droop (or speed regulation) and self-regulation coefficient. These travelling-wave solutions are then compared to numerical solution by the method of characteristics with close agreement in the results. This new analytical method is then used to study the influence of elasticity on maximum speed deviation and on the stability of oscillations and to define the limitation of a rigid-column analysis. For high-head plants, elasticity of the water and penstock walls increases maximum speed if governor settings are kept the same. The major influence of the elastic waves, however, is the reduction of the stability margin for the speed variation. Optimum governor settings will be, therefore, different from those obtained by neglecting elasticity of the water and penstock walls.
