description: Gaussian Process Regression (GPR) is a widely used surrogate model in efficient global optimization (EGO) due to its capability to provide uncertainty estimates in the prediction. The cost of creating a GPR model for large data sets is high. On the other hand, neural network (NN) models scale better compared to GPR as the number of samples increase. Unfortunately, the uncertainty estimates for NN prediction are not readily available. In this work, a scalable algorithm is developed for EGO using NN-based prediction and uncertainty (EGONN). Initially, two different NNs are created using two different data sets. The first NN models the output based on the input values in the first data set while the second NN models the prediction error of the first NN using the second data set. The next infill point is added to the first data set based on criteria like expected improvement or prediction uncertainty. EGONN is demonstrated on the optimization of the Forrester function and a constrained Branin function and is compared with EGO. The convergence criteria is based on the maximum number of infill points in both cases. The algorithm is able to reach the optimum point within the given budget. The EGONN is extended to handle constraints explicitly and is utilized for aerodynamic shape optimization of the RAE 2822 airfoil in transonic viscous flow at a free-stream Mach number of 0.734 and a Reynolds number of 6.5 million. The results obtained from EGONN are compared with the results from gradient-based optimization (GBO) using adjoints. The optimum shape obtained from EGONN is comparable to the shape obtained from GBO and is able to eliminate the shock. The drag coefficient is reduced from 200 drag counts to 114 and is close to 110 drag counts obtained from GBO. The EGONN is also extended to handle uncertainty quantification (uqEGONN) using prediction uncertainty as an infill method. The convergence criteria is based on the relative change of summary statistics such as mean and standard deviation of an uncertain quantity. The uqEGONN is tested on Ishigami function with an initial sample size of 100 samples and the algorithm terminates after 70 infill points. The statistics obtained from uqEGONN (using only 170 function evaluations) are close to the values obtained from directly evaluating the function one million times. uqEGONN is demonstrated on to quantifying the uncertainty in the airfoil performance due to geometric variations. The algorithm terminates within 100 computational fluid dynamics (CFD) analyses and the statistics obtained from the algorithm are close to the one obtained from 1000 direct CFD based evaluations.

The impact of work orientation on career, compassion, and creativity
Creators: name: Schabram, Kira Franziska
Publisher: name: University of British Columbia
Year: 2016

description: Employees can espouse one of three work orientations: They may see their work as a job, as a necessity to support meaningful life experiences, as a career, a channel for advancement, or as a calling, a fulfilling vocation that provides personal, moral, and social significance. To date, little research has systematically compared behaviors associated with the three work orientations or sought to explain their underlying mechanisms. In this three-paper dissertation, I consider the impact of one or more work orientation on three types of employee behaviors. Study 1 is a qualitative study of 50 employees with a calling orientation that outlines how these individuals negotiate the challenges of their work. In study 2, a two-period survey of 182 social-service employees, I provide evidence that only the calling orientation is associated with greater compassionate action (kindness, help) towards coworkers because such employees operate at a higher cognitive construal level. Finally, the results of study 3, a cross-sectional survey of 283 employees across nine organizations, indicate a significant relationship between the job and career orientation and the two regulatory foci (promotion- and prevention focus), but do not support the baseline hypothesis that such regulatory foci would impact subsequent creative behavior. Theoretical and practical implications are discussed.

description: In 1963—a racially-charged time in the United States—James Baldwin delivered “A Talk to Teachers,” urging educators to engage youth in difficult conversations about current events. We concur with Giroux (2011, 2019) that political forces influence our educational spaces and that classrooms should not be viewed as apolitical, but instead seen as sites for engagement, where educators and artists alike can “go for broke.” Drawing upon A Tribe Called Quest’s 2017 Grammy performance of “We the People...” as an example of the role of the arts in troubled times, we consider ways to work alongside youth in schools to respond, consider, and process current events through music.

description: We demonstrate experimentally and theoretically that a nanoscale hollow channel placed centrally in the solid glass core of a photonic crystal fiber strongly enhances the cylindrical birefringence (the modal index difference between radially and azimuthally polarized modes). Furthermore, it causes a large split in group velocity and group velocity dispersion. We show analytically that all three parameters can be varied over a wide range by tuning the diameters of the nanobore and the core.

description: We propose and analyze different schemes to probe the quantum nature of nanoelectromechanical systems (NEMS) by a tunnel junction detector. Using the Keldysh technique, we are able to investigate the dynamics of the combined system for an arbitrary ratio of $eV/\hbar Ω$, where V is the applied bias of the tunnel junction and $Ω$ the eigenfrequency of the oscillator. In this sense, we go beyond the Markov approximation of previous works where these parameters were restricted to the regime $eV/\hbar Ω\gg 1$. Furthermore, we also go beyond the Born approximation because we calculate the finite frequency current noise of the tunnel junction up to fourth order in the tunneling amplitudes. Interestingly, we discover different ways to probe both position and momentum properties of NEMS. On the one hand, for a non-stationary oscillator, we find a complex finite frequency noise of the tunnel junction. By analyzing the real and the imaginary part of this noise separately, we conclude that a simple tunnel junction detector can probe both position- and momentum-based observables of the non-stationary oscillator. On the other hand, for a stationary oscillator, a more complicated setup based on an Aharonov-Bohm-loop tunnel junction detector is needed. It still allows us to extract position and momentum information of the oscillator. For this type of detector, we analyze for the first time what happens if the energy scales $eV$, $\hbar Ω$, and $k_B T$ take arbitrary values with respect to each other where T is the temperature of an external heat bath. Under these circumstances, we show that it is possible to uniquely identify the quantum state of the oscillator by a finite frequency noise measurement.

Exploiting Contextual Independence In Probabilistic Inference

name: Zhang, N. L.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Artificial Intelligence (cs.AI)
subject: FOS: Computer and information sciences

description: Bayesian belief networks have grown to prominence because they provide compact representations for many problems for which probabilistic inference is appropriate, and there are algorithms to exploit this compactness. The next step is to allow compact representations of the conditional probabilities of a variable given its parents. In this paper we present such a representation that exploits contextual independence in terms of parent contexts; which variables act as parents may depend on the value of other variables. The internal representation is in terms of contextual factors (confactors) that is simply a pair of a context and a table. The algorithm, contextual variable elimination, is based on the standard variable elimination algorithm that eliminates the non-query variables in turn, but when eliminating a variable, the tables that need to be multiplied can depend on the context. This algorithm reduces to standard variable elimination when there is no contextual independence structure to exploit. We show how this can be much more efficient than variable elimination when there is structure to exploit. We explain why this new method can exploit more structure than previous methods for structured belief network inference and an analogous algorithm that uses trees.

description: Wireless ad hoc networks are power constrained since nodes operate with limited battery energy. Thus, energy consumption is crucial in the design of new ad hoc routing protocols. In order to maximize the lifetime of ad hoc networks, traffic should be sent via a route that can be avoid nodes with low energy. In addition, considering that the nodes of ad hoc networks are mobile, it is possible that a created path is broken because of nodes mobility and establishment of a new path would be done again. This is because of sending additional control packets, accordingly, energy consumption increases. Also, it should avoid nodes which have more buffered packets. Maybe, because of long queue, some of these packets are dropped and transmitted again. This is the reason for wasting of energy. In this paper we propose a new energy efficient algorithm, that uses a new cost function and avoid nodes with characteristics which mentioned above. We show that this algorithm improves the network energy consumption by using this new cost function.

description: Many species of turtle are facing serious declines from multiple anthropogenic causes. One such turtle native to the United States, the Blanding’s Turtle (Emydoidea blandingii), has faced declines in nearly every sector of their range, yet few populations have known recorded demographics, such as abundance, density, sex ratio, and body sizes. To inform managers of these crucial demographic measures of three spatially adjacent populations on Camp Grayling, MI, I implemented a capture-mark-recapture study from 2021 to 2022. I calculated Lincoln-Petersen Index and ran constant, time-varying, and behavioral response models for both full and conditional likelihoods in Program MARK. All best fit models estimated populations ≥30. The three populations sampled at Camp Grayling were low in abundance, densities, and biomass compared to some more well-known populations. Adult body weight means were 1456 g and 1223 g for males and females, respectively. Mean carapace lengths for males was 22.42 cm and females were 20.11 cm. The males of these populations were significantly larger than the mean found across the Blanding’ Turtles range. There is evidence of recruitment within these populations. A long-term research plan should be implemented and focus on investigating connectedness of these populations, as well as building data for population viability analyses. Additionally, immediate conservation action should take place to protect this vulnerable species.
When Physical is Not Real Enough

description: This position paper argues that policies for physical memory management and for memory power mode control should be relocated to the system software of a programmable memory management controller (MMC). Similarly to the mapping of virtual to physical addresses done by an MMU of a processor, this controller offers another level of mapping from physical addresses to real addresses in a multi-bank multi-technology (DRAM, MRAM, FLASH) memory system. Furthermore, the programmable memory controller is responsible for the allocation and migration of memory according to power and performance demands.
Our approach dissociates the aspects of memory protection and sharing from the aspect of energy-aware management of real memory. In this way, legacy operating systems do not have to be extended to reduce memory power dissipation, and power-aware memory is no longer limited to CPUs with an MMU.

description: We present new UVES spectra of a sample of 14 mostly cool unevolved stars with planetary companions with the aim of studying possible differences in Be abundance with respect to stars without detected planets. We determine Be abundances for these stars that show an increase in Be depletion as we move to lower temperatures. We carry out a differential analysis of spectra of analog stars with and without planets to establish a possible difference in Be content. While for hot stars no measurable difference is found in Be, for the only cool (Teff ~ 5000 K) planet host star with several analogs in the sample we find enhanced Be depletion by 0.25 dex. This is a first indication that the extra-depletion of Li in solar-type stars with planets may also happen for Be, but shifted towards lower temperatures (Teff < 5500 K) due to the depth of the convective envelopes. The processes that take place in the formation of planetary systems may affect the mixing of material inside their host stars and hence the abundances of light elements.

description: Vela X is a large, 3x2 degrees, radio-emitting pulsar wind nebula (PWN) powered by the Vela pulsar in the Vela supernova remnant. Using four Suzaku/XIS observations pointed just outside Vela X, we find hard X-ray emission extending throughout the fields of view. The hard X-ray spectra are well represented by a power-law. The photon index is measured to be constant at Gamma~2.4, similar to that of the southern outer part of Vela X. The power-law flux decreases with increasing distance from the pulsar. These properties lead us to propose that the hard X-ray emission is associated with the Vela PWN. The larger X-ray extension found in this work strongly suggests that distinct populations relativistic electrons form the X-ray PWN and Vela X, as was recently inferred from multiwavelength spectral modeling of Vela X.

description: In this article we present an algorithm to compute bounds on the marginals of a graphical model. For several small clusters of nodes upper and lower bounds on the marginal values are computed independently of the rest of the network. The range of allowed probability distributions over the surrounding nodes is restricted using earlier computed bounds. As we will show, this can be considered as a set of constraints in a linear programming problem of which the objective function is the marginal probability of the center nodes. In this way knowledge about the maginals of neighbouring clusters is passed to other clusters thereby tightening the bounds on their marginals. We show that sharp bounds can be obtained for undirected and directed graphs that are used for practical applications, but for which exact computations are infeasible.
Dynamic Thermal Management for Distributed Systems

Publisher: name: Karlsruhe
Year: 2004

description: In modern data centers, the impact on the thermal properties by increased scale and power densities is enormous and poses new challenges on the designers of both computing as well as cooling systems. Controltheoretic techniques have proven to manage the heat dissipation and the temperature to avoid thermal emergencies, but are not aware of the task currently executing or its specific service requirements. In this work we investigate an approach to dynamic thermal management with respect to the demands of individual applications, users or services. We show that the energy consumption and the temperature can be determined on a fine grained level and without the need for measurement, using information from event monitors embedded in modern processors. We extend the well-known abstraction of resource containers to an infrastructure for transparent energy and temperature management in distributed systems. The processing of a request can be throttled to meet the thermal requirements of the system, even if machine boundaries are crossed, e.g. by remote procedure calls in a client/server relationship. With this facility, energy consumption can be accounted and the resulting heat generation be controlled precisely without the need for expensive hardware. Experiments on a Pentium 4 architecture show that energy and temperature are accurately determined and thermal limits for the individual CPU and the whole distributed system will not be exceeded. Use cases and important implications of our approach are discussed.

description: Non-destructive characterization of multi-layered structures that can be accessed from only a single side is important for applications such as well-bore integrity inspection. Collimated beam ultrasound systems are a technology for imaging inside multi-layered structures such as geothermal wells. These systems work by using a collimated narrow-band ultrasound transmitter that can penetrate through multiple layers of heterogeneous material. A series of measurements can then be made at multiple transmit frequencies. However, commonly used reconstruction algorithms such as Synthetic Aperture Focusing Technique (SAFT) tend to produce poor quality reconstructions for these systems both because they do not model collimated beam systems and they do not jointly reconstruct the multiple frequencies.
 In this thesis, we first propose a multi-frequency ultrasound model-based iterative reconstruction (UMBIR) algorithm designed for multi-frequency collimated beam ultrasound systems. The combined system targets reflective imaging of heterogeneous, multi-layered structures. For each transmitted frequency band, we introduce a physics-based forward model to accurately account for the propagation of the collimated narrow-band ultrasonic beam through the multi-layered media. We then show how the joint multi-frequency UMBIR reconstruction can be computed by modeling the direct arrival signals, detector noise, and incorporating a spatially varying image prior.
 We also propose a ringing artifact reduction method for ultrasound image reconstruction that uses a multi-agent consensus equilibrium (RARE-MACE) framework. Our approach integrates a physics-based forward model that accounts for the propagation of a collimated ultrasonic beam in multi-layered media, a spatially varying image prior, and a denoiser designed to suppress the ringing artifacts that are characteristic of reconstructions from high-fractional bandwidth ultrasound sensor data.
 Results using both simulated and experimental data indicate that multi-frequency UMBIR reconstruction yields much higher reconstruction quality than either single frequency UMBIR or SAFT. In addition, our results demonstrate the capability of our RARE-MACE method to suppress ringing artifacts and substantially improve the image quality over single frequency UMBIR and SAFT.

description: A large fraction of brown dwarfs and low-mass stars may form by gravitational fragmentation of relatively massive (a few 0.1 Msun), extended (a few hundred AU) discs around Sun-like stars. We present an ensemble of radiative hydrodynamic simulations that examine the conditions for disc fragmentation. We demonstrate that this model can explain the low-mass IMF, the brown dwarf desert, and the binary properties of low-mass stars and brown dwarfs. Observing discs that are undergoing fragmentation is possible but very improbable, as the process of disc fragmentation is short lived (discs fragment within a few thousand years).

In this paper we have study the essentials SEO techniques, such as; directory submission, keyword generation and link exchanges. The impact of SEO techniques can be applied as marketing technique and to get top listing in major search engines like Google, Yahoo, and MSN. Our study focuses on these techniques from four different companies' perspectives of United Kingdom and Pakistan. According to the these companies, these techniques are low cost and high impacts in profit, because mostly customers focus on major search engine to find different products on internet, so SEO technique provides best opportunity to grow their business. This paper also describes the pros and cons of using these searh engine optimization techniques in above four companies. We have concluded that these techniques are essential to increase their business profit and minimize their marketing cost.

UNITE was a 3U CubeSat without deployables that was passively stabilized magnetically and aerodynamically. The UNITE CubeSat reentered the atmosphere on October 21, 2021, its 995th day in orbit. One of the mission objectives of UNITE was to track its orbital decay with the intent of updating CubeSat drag models. The original predicted mission lifetime of 428 days was based on results from a spreadsheet available with Space Mission Engineering: The New SMAD, using standard CubeSat parameters and simply assuming “solar mean” for the solar cycle. To more accurately understand the actual orbital behavior known from the TLEs (two-line elements), a completely new algorithm was coded for orbital drag, but taking into account varying atmospheric densities consistent with the variability of the actual solar cycle experienced between January 2019 and October 2021. Using the algorithm and the updated atmospheric density model, the mission time was computed to be 976 days, only 19 days short of the actual mission time. Next, the drag coefficient was adjusted from 2.2 to 2.08, and with that change the algorithm correctly calculated the 995 days in orbit. Also of note, in the process o f the development of the algorithm, a slight error was discovered in the Bessel function table available through The New SMAD, and that was corrected, as well. The new algorithm, developed by the undergraduate student, was implemented in an Excel program and is readily available for use by other teams. With the implementation of a new algorithm that accounts for solar cycle activity and allows for drag coefficient adjustment, it is hoped that future CubeSat teams will be able to predict mission life and the orbital decay more accurately.

An extension to the Hermite-Joubert problem
Creators: name: Brassil, Matthew
Publisher: name: University of British Columbia
Year: 2016

description: Let E/F be a field extension of degree n. A classical problem is to find a generating element in E whose characteristic polynomial over F is as simple is possible. An 1861 theorem of Ch. Hermite [5] asserts that for every separable field E/F of degree n there exists an element a ∈ E whose characteristic polynomial is of the form f(x) = x⁵ +b₂x³ +b₄x+b₅ or equivalently, tr{E/F}(a) = tr{E/F}(a³) = 0. A similar result for extensions of degree 6 was proven by P. Joubert in 1867; see [6]. In this thesis we ask if these results can be extended to field extensions of larger degree. Specifically, we give a necessary and sufficient condition for a field F, a prime p and an integer n ≥ 3 to have the following property: Every separable field extension E/F of degree n contains an element a ∈ E such that a generates E over F, and tr{E/F}(a) = tr{E/F}(a^p) = 0. As a corollary we show for infinitely many new values of n that the theorems of Hermite and Joubert do not extend to field extensions of degree n. We conjecture the same for more values of n and provide computational evidence for a large number of these.
On Polynomial Sized MDP Succinct Policies

description: Policies of Markov Decision Processes (MDPs) determine the next action to execute from the current state and, possibly, the history (the past states). When the number of states is large, succinct representations are often used to compactly represent both the MDPs and the policies in a reduced amount of space. In this paper, some problems related to the size of succinctly represented policies are analyzed. Namely, it is shown that some MDPs have policies that can only be represented in space super-polynomial in the size of the MDP, unless the polynomial hierarchy collapses. This fact motivates the study of the problem of deciding whether a given MDP has a policy of a given size and reward. Since some algorithms for MDPs work by finding a succinct representation of the value function, the problem of deciding the existence of a succinct representation of a value function of a given size and reward is also considered.

description: We examined the experiences of 95 lesbian, gay, bisexual, transgender, and queer (LGBTQ+) music education majors, along with 39 heterosexual allies, who were student members of the Texas Music Educators Association. Participants addressed curricular practices and institutional factors that lend themselves to LGBTQ+ inclusion and safety among students, faculty, and staff. We collected data through an anonymous online survey, which included questions related to LGBTQ+ students’ experiences in their programs and across campuses. Five students participated in follow-up interviews designed to provide more in-depth information about their classroom experiences and campus-level actions taken to promote systemic change. Through multivariate analyses, as well as content analysis of the qualitative data, we found that although preservice music teachers in Texas feel accepted and supported in their music teacher education programs, they are entering the field feeling underprepared to address LGBTQ+ issues and support students who identify as such.
Time dependent configuration interaction simulations of spin swap in spin orbit coupled double quantum dots

description: We perform time-dependent simulations of spin exchange for an electron pair in laterally coupled quantum dots. The calculation is based on configuration interaction scheme accounting for spin-orbit (SO) coupling and electron-electron interaction in a numerically exact way. Noninteracting electrons exchange orientations of their spins in a manner that can be understood by interdot tunneling associated with spin precession in an effective SO magnetic field that results in anisotropy of the spin swap. The Coulomb interaction blocks the electron transfer between the dots but the spin transfer and spin precession due to SO coupling is still observed. The electron-electron interaction additionally induces an appearance of spin components in the direction of the effective SO magnetic field which are opposite in both dots. Simulations indicate that the isotropy of the spin swap is restored for equal Dresselhaus and Rashba constants and properly oriented dots.
Bilddaten getriebene Kinematik-Simulation für den Roboter gestützten Kreuzband- und Kniegelenkersatz [online]
Creators: name: Meister, Dietmar

description: Kurzfassung

In zunehmendem Maße wird in der Medizin eine immer höhere
Präzision bei immer komplexeren Eingriffen gefordert. Beim
Ersatz des Kniegelenks oder des vorderen Kreuzbandes wird dieser
Forderung mit einem wachsenden Anteil an Computer und Roboter
gestützten Operationstechniken begegnet. Da für die Planung
einer Knieoperation die Bewegung im Kniegelenk von besonderer
Bedeutung ist, wird in dieser Arbeit ein Verfahren entwickelt,
um die Bewegung auf Basis der in den Computer gestützten
Systemen verwendeten Bilddaten zu simulieren.
Die Grundlage für das Simulationsmodell bilden Bild- und
Bewegungsdaten von 26 Probanden. Da kein Verfahren für eine
Bewegungsaufnahme bekannt ist, mit dem die Position der
beteiligten Knochen ausreichend genau bestimmt werden kann, ohne
den Patienten zu verletzen, wird ein neues Verfahren entwickelt
und zusammen mit den Weiterentwicklungen von zwei bekannten
invasiven Verfahren angewendet und validiert.
Für die Modellbildung wird jeder Proband mit einem Merkmalvektor
beschrieben, der sich aus Merkmalen für die Knochenform und aus
Merkmalen für die Bewegung zusammensetzt. Da die Bewegung eines
Kniegelenks zwingend mit der Form der Knochen verbunden ist,
kann für einen neuen Patienten unter Verwendung seiner
Formmerkmale im Merkmalraum ein ähnlicher Datensatz des Modells
gefunden werden. Aus den gewonnenen Bewegungsmerkmalen lässt
sich die komplette Bewegung zu einem neuen Patienten
rekonstruieren, ohne diese Bewegung aufgenommen zu haben.
Mit dem entwickelten Modell für die Simulation von
Bewegungsdaten auf Basis der für viele Computer gestützte
Knieoperationen verwendeten Volumendaten ist es gelungen, den
neuen Operationstechniken wichtige Informationen über den
individuellen Bewegungsablauf eines Knies zu liefern und die
Qualität der Planungen zu steigern.

description: We are searching for the action principle for multiple M0-brane (multiple M-wave or mM0) system starting from the mM0 equations of motion obtained in the frame of superembedding approach. Surprisingly, the way from these equations to the action happens to be hampered by a problem which suggests a possible generalization of the action principle which we call "hierarchical action principle".
