description: About 20% of global electricity production is consumed in rotary equipment to convey fluids such as water, gas, air, and other liquids, while the loss of energy consumption in this sector is more than 60%. The aim of this study was to evaluate different efficiencies in the pumping stations in the pressurized irrigation systems to address low energy efficiency issues in the pump stations and to develop solutions to enhance it. In this regard, the electrical efficiency, hydraulic efficiency, and mechanical efficiency were determined in the studied pump stations and they were used to determine total efficiency of each pump station. Pump station assessment tool (PSAT) software was used to model each station and predict annual energy consumption costs; furthermore, the potential of efficiency improvement was calculated. Results showed that the total efficiency of the studied pump stations ranged from 13 to 32% and averaged 24%. Factors, such as improper design, disproportion in terms of the operation conditions, and the design and improper operation, caused a drop in the efficiency of the pump stations. Also, the productivity of the energy consumption in the pump stations can be improved from 24 to 49% if these issues are tackled.

"Museum Workout" engages with the history of The Met to produce a provocative, engaging, and humorous critique of the art canon.
Mr. America's Creator: The Race Science of Dr. Ales Hrdlicka, 1896-1943
Creators: Magaña, Linda
Publisher: name: Columbia University
Year: 2011
Subjects: History

description: After nearly half a century’s work to establish the field of American physical
anthropology, Dr. Ales Hrdlicka1 died quietly in his home in Washington, D.C. on September 5,
1943. A leading public intellectual, Hrdlicka had been the director of physical anthropology at
the Smithsonian Institute for forty years. He was an original proponent of the Bering Strait
theory of migration, at the time a controversial position arguing that the first humans in the
Americas migrated from Asia across a land bridge roughly 12,000 years ago. A survey of
Hrdlicka’s resume, full of similarly impressive accomplishments, glosses over the nuanced and
complicated intellectual development of this Bohemian-born American physical anthropologist.
This thesis explores the tension embedded in Dr. Hrdlicka’s conceptual vision, a vision limited
by his—and to a large extent, the nation’s—obsession with the quantification of race.

Multi Modality Drug Abuse Treatment Program for High Economic-Status Patients

Subjects: Social service

description: This study was a pre-post, single group evaluation of a drug-abuse treatment program at a private psychiatric hospital located in the north eastern United States.

Subjects consisted of 101 consecutive atypical patient admissions. They were predominantly white male professionals in their late twenties who earned almost $45,000 per year and had about two years of college.

The data-base included patient information obtained using: The Addiction Severity Index (ASI), The Brief Psychiatric Rating Scale, The Beck Depression Scale, drug history variables and a natural support systems matrix.

Seventy-four of the patients successfully completed the inpatient treatment protocol, 26 did not and 1 died. Subsequently, 51 entered the outpatient program.

Telephone followups on the patients were carried out 3.5 months post discharge from the inpatient program; on these interviews the ASI was administered. At these followups 51 subjects were found to be readdicted, 46 were drug free and data for 4 were unobtainable.

The relationships of social, psychological and biochemical factors to occurrence and severity of drug use at post-treatment followups were examined.

The analytic strategy employed chi square, correlation, hierarchical multiple regression, and residualized change score analyses.

The results indicated that the longer a patient remained in treatment the more likely he was to be drug free at followup, especially if the patient entered the outpatient program.

Antecedent factors predicting longer length of stay in treatment were (1) strong economic support status and (2) the existence of a supportive conjugal dyad.

Two other antecedent factors were directly related to incidence of readdiction and its severity at followup. First, the greater the degree of pre-treatment legal involvement the greater the probability and severity of post-treatment readdiction. Second, the type of pre-induction drug of abuse predicted post-treatment readdiction and severity--methadone being the greatest predictor followed in order by "speedball" (a mixture of heroin and cocaine), heroin and cocaine. Additionally, it was found that the subjects taking psychotropic medication during the inpatient and continuing into outpatient phase of treatment were the most likely to be drug-free at followup, especially for the high psychiatric severity patients.

description: The characterization of the formation mechanisms of amorphous solids is a large avenue for research, since understanding its non-Arrhenius behavior is challenging to overcome. In this context, we present one path toward modeling the diffusive processes in supercooled liquids near glass transition through a class of non-homogeneous continuity equations, providing a consistent theoretical basis for the physical interpretation of its non-Arrhenius behavior. More precisely, we obtain the generalized drag and diffusion coefficients that allow us to model a wide range of non-Arrhenius processes. This provides a reliable measurement of the degree of fragility of the system and an estimation of the fragile-to-strong transition in glass-forming liquids, as well as a generalized Stokes-Einstein equation, leading to a better understanding of the classical and quantum effects on the dynamics of non-additive stochastic systems.

Our main result is an expression for the octagon form factor as determinant of a semi-infinite matrix. We find that at weak coupling the entries of this matrix are linear combinations of ladder functions with simple rational coefficients and give the full perturbative expansion of the octagon.

It is found that the phase portrait in the reconstructed state space of the time series of the segment from the Korean traditional song has a more complex structure in comparison with the segment from the western songs. The segment from the Korean traditional song has the correlation dimension 4.4 and two positive Lyapunov exponents which show that the dynamic related to the Korean traditional song is a high dimensional hyperchaotic process. On the other hand, the segment from the western song with only one positive Lyapunov exponent and the correlation dimension 2.5 exhibits low dimensional chaotic behavior.

Tailings dams : design criteria and safety evaluations at closure
Creators: name: Szymanski, Maciej B. (Maciej Boleslaw)
name: Davies, Michael Paul, 1961-
Publisher: name: The University of British Columbia
Year: 2009

description: The majority of currently available dam safety guidelines do not account well for the specifics of tailings dams. In the guidelines commonly used in Canada, tailings dams are addressed alongside water retention (conventional) dams. This results in an user-unfriendly, and potentially unsafe and/or inappropriate, treatment of safety aspects specific to tailings dams. A number of guidelines developed for tailings dams have been published by the International Commission on Large Dams (ICOLD). Except for one of those guidelines (ICOLD 1989), a focus on the tailings dam safety is not provided. In particular, there seem to be very few and largely incomplete guidelines that speak to dam safety aspects specific to the tailings dam closure phase. Unlike for a conventional dam that would typically be breached upon the end of its useful life, the closure phase will be by far the longest state of being for a tailings dam, regardless of how long the dam was in operational use. This paper identifies and examines a number of tailings dam design criteria and safety requirements applicable to the closure phase, and concludes that many of such requirements must currently be selected on a case-by-case basis without support of sufficiently comprehensive guidelines.

Multi-Level Governance of Agricultural Land in Japan: Farmers’ Perspectives and Responses to Farmland Banking

description: This dissertation examines the emergence and implementation of a new intermediary mechanism of farmland tenancy in Japan with a focus on farmers’ perspectives. Japan’s government introduced the Farmland Bank (FB) program in 2014 in an attempt to avoid further farmland abandonment and revitalize the farming industry. By design, the program gives more power to prefectural authorities to accommodate new actors and resources in tenancy arrangements even without farmland owners’ consent so as to expedite farmland aggregation and generate better economies of scale. This is a major turning point since the postwar agrarian reform where owners have been given a primary decision-making role in private farmland use. The research draws on semi-structured interviews with farmers, government officials and experts, which were conducted intermittently between 2016 and 2018. By taking a multi-level governance approach, the study shows a change in the farmland governance model from the centralized control of individual property to the decentralized, multi-level coordination for collective tenancy arrangements, to which farmers actively contributed along with the interlocking institutional transitions of farming families and villages. With the decline in the life security function of farmland, they have increasingly disengaged from farming and allowed for political and conceptual shifts of farmland from owner-oriented to user-driven and from family property to the commons of the society. The study finds that despite a massive budget injection, the FB program has only marginally facilitated farmland aggregation. Yet, the case study of two communities reveals that the program has been driving a ‘soft’ coercion of farmers’ land-use practices via economic rationality. Moreover, it has disconnected owners from farmland but failed to enshrine tenants’ commitment to long-term farmland management. Complementary attention to subjective, intangible and cultural aspects of farmland would help to avoid possible one-time profit seeking land-use.

description: Effect of contact interfaces, between metallic single-wall carbon nanotubes (SWCNT) and external electrodes made also of nanotubes, on the electrical conductance is studied. A tight-binding model with both diagonal and off-diagonal disorder, a recursive Green function technique as well as the Landauer formalism are used. The studies are carried out within the coherent transport regime and are focused on: (i) evolution from conductance quantization to resonant tunneling, (ii) SWCNT's length effects and (iii) magnetoresistance. It is shown that the so-called on-resonance devices, i.e. nanotubes having a conductance peak at the Fermi energy, occur with a period of 3 carbon inter-ring spacings. Additionally, the present approach provides an insight into magnetoresistance dependence of SWCNTs on conditions at the contact interface.

description: We derive a semiclassical trace formula for a symmetry reduced part of the spectrum in axially symmetric systems. The classical orbits that contribute are closed in (ρ,z,p_ρ,p_z) and have p_ϕ= m\hbar where m is the azimuthal quantum number. For m > 0, these orbits vary with energy and almost never lie on periodic trajectories in the full phase space in contrast to the case of discrete symmetries. The transition from m=0 to m > 0 is however not dramatic as our numerical results indicate, suggesting that contributing orbits occur in topologically equivalent families within which p_ϕvaries smoothly.

description: One particular approach to quantum groups (matrix pseudo groups) provides the Manin quantum plane. Assuming an appropriate set of non-commuting variables spanning linearly a representation space one is able to show that the endomorphisms on that space preserving the non-commutative structure constitute a quantum group. The non-commutativity of these variables provide an example of non-commutative geometry. In some recent work we have shown that quantum Clifford algebras --i.e. Clifford algebras of an arbitrary bilinear form-- are closely related to deformed structures as q-spin groups, Hecke algebras, q-Young operators and deformed tensor products. The natural question of relating Manin's approach to quantum Clifford algebras is addressed here. Some peculiarities are outlined and explicite computations using the Clifford Maple package are exhibited. The meaning of non-commutative geometry is re-examined and interpreted in Clifford algebraic terms.

description: Background The pre-season preparatory period is considered key for optimizing the physical fitness levels needed to withstand congested match periods and preventing injuries during the regular soccer season. This study contrasted the effects s of neuromuscular training (NMT) versus an endurance-dominated training (ET) program conducted during the preseason on measures of physical fitness and injury occurrence in female soccer players. Methods Twenty-four female soccer players aged 17.0 ± 1.3 years from a professional soccer club participated in this study. Players were randomly assigned to NMT (n = 12) or ET (n = 12) groups according to their playing position. The preseason intervention program lasted six weeks, with three weekly sessions with a duration of 45–60 min per session. Exercises in the NMT group included muscle strengthening exercises, plyometrics, agility and dynamic stability exercises, while the ET group practiced a traditional pre-season training program consisting of running and sprinting exercises, fartlek, and high-intensity interval training. The training volumes were similar in the two study groups. Anthropometric measurements, physical fitness tests (i.e., linear and change-of-direction speed, muscle strength and power tests) and the overall injury rate per 1000 h of exposure (training, match) were recorded throughout the season. Results No between group differences were found at pre (T1). Significant group-by-time interactions were observed for the 5, 10, and 30-m linear sprint speed tests (p < 0.001, 2.16 < d < 2.58), the T-test (p = 0.024, d = 1.03), the squat (p < 0.001, d = 4.04), and the countermovement jump test (p < 0.001, d = 2.21), the Loughborough soccer passing test (LSPT) (p = 0.019, d = 1.08), and the 1-RM back squat test (p < 0.001, d = 2.53). Post-hoc tests indicated that NMT provided larger improvements for SJ, CMJ, 1-RM back squat, the 5-m sprint, 10-m sprint, 30-m sprint, T-test and LSPT compared to ET (1.07 > d > 2.77). The injury rate across the season was significantly lower in the NMT (5.1/1000 h exposure) compared to ET (11.8/1000 h exposure) (p = 0.014). Conclusions The findings support that six-weeks of preseason NMT versus ET induced larger performance improvements, and significantly reduced injury occurrence in elite female soccer players.

description: Process control is essential in chemical engineering and has diverse applications in automation, manufacturing, scheduling, etc. In this cross-disciplinary work, we shift the domain focus from the control of machines to the control of multiple intelligent agents. Our goal is to improve the optimization problem-solving process, such as optimal regulation of emerging technologies, in a multi-agent system. Achieving that improvement would have potential value both within and outside the chemical engineering community. This work also illustrates the possibility of applying process systems engineering techniques, especially process control, beyond chemical plants.
      It is very common to observe crowds of individuals solving similar problems with similar information in a largely independent manner. We argue here that the crowds can become more efficient and robust problem-solvers, by partially following the average opinion. This observation runs counter to the widely accepted claim that the wisdom of crowds deteriorates with social influence. The key difference is that individuals are self-interested and hence will reject feedbacks that do not improve their performance. We propose a multi-agent control-theoretic methodology, soft regulation, to model the collective dynamics and compute the degree of social influence, i.e., the level to which one accepts the population feedback, that optimizes the problem-solving performance.
      Soft regulation is a modeling language for multi-agent sociotechnical systems. The state-space formulation captures the individual learning process (i.e., open loop dynamics) as well as the influence of the population feedback in a straightforward manner. It can model a diverse set of existing multi-agent dynamics. Through numerical analysis and linear algebra, we attempt to understand the role of feedback in multi-agent collective dynamics, thus achieving multi-agent control in sociotechnical systems.
      Our analysis through mathematical proofs, simulations, and a human subject experiment suggests that intelligent individuals, solving the same problem (or similar problems), could do much better by adaptively adjusting their decisions towards the population average. We even discover that the crowd of human subjects could self-organize into a near-optimal setting. This discovery suggests a new coordination mechanism for enhancing individual decision-making. Potential applications include mobile health, urban planning, and policymaking.

description: Repetitive control (RC) systems aim to achieve zero tracking error when tracking a periodic command, or when tracking a constant command in the presence of a periodic disturbance, or both a periodic command and periodic disturbance. This dissertation presents a new approach using Taylor Series Expansion of the inverse system z-transfer function model to design Finite Impulse Response (FIR) repetitive controllers for single-input single-output (SISO) systems, and compares the designs obtained to those generated by optimization in the frequency domain. This approach is very simple, straightforward, and easy to use. It also supplies considerable insight, and gives understanding of the cause of the patterns for zero locations in the optimization based design. The approach forms a different and effective time domain design method, and it can also be used to guide the choice of parameters in performing in the frequency domain optimization design. Next, this dissertation presents the theoretical foundation for frequency based optimization design of repetitive control design for multi-input multi-output (MIMO) systems. A comprehensive stability theory for MIMO repetitive control is developed. A necessary and sufficient condition for asymptotic stability in MIMO RC is derived, and four sufficient conditions are created. One of these is the MIMO version of the approximate monotonic decay condition in SISO RC, and one is a necessary and sufficient condition for stability for all possible disturbance periods. An appropriate optimization criterion for direct MIMO is presented based on minimizing a Frobenius norm summed over frequencies from zero to Nyquist. This design process is very tractable, requiring only solution of a linear algebraic equation. An alternative approach reduces the problem to a set of SISO design problems, one for each input-output pair. The performances of the resulting designs are studied by extensive examples. Both approaches are seen to be able to create RC designs with fast monotonic decay of the tracking error. Finally, this dissertation presents an analysis of using an experiment design sequence for parameter identification based on the theory of iterative learning control (ILC), a sister field to repetitive control. This is suggested as an alternative to the results in optimal experiment design. Modified ILC laws that are intentionally non-robust to model errors are developed, as a way to fine tune the use of ILC for identification purposes. The non-robustness with respect to its ability to improve identification of system parameters when the model error is correct is studied. It is demonstrated that in many cases the approach makes the learning particularly sensitive to relatively small parameter errors in the model, but sensitivity is sometimes limited to parameter errors of a specific sign.

description: A one-dimensional Ising model with nearest neighbour interactions is applied to study compaction processes in granular media. An equivalent particle-hole picture is introduced, with the holes being associated to the domain walls of the Ising model. Trying to mimic the experiments, a series of taps separated by large enough waiting times, for which the system freely relaxes, is considered. The free relaxation of the system corresponds to a T=0 dynamics which can be analytically solved. There is an extensive number of metastable states, characterized by all the holes being isolated. In the limit of weak tapping, an effective dynamics connecting the metastable states is obtained. The steady state of this dynamics is analyzed, and the probability distribution function is shown to have the canonical form. Then, the stationary state is described by Edwards thermodynamic granular theory. Spatial correlation functions in the steady state are also studied.

description: This dissertation presents multi-photon spectroscopic studies on molecule/metal interfaces and graphene. Two different aspects of these ultrathin molecular or atomic materials were investigated: (1) the electronic structure of molecule/metal interfaces and (2) nonlinear optical properties of graphene.
For the case (1), two-photon photoemission (TPPE) using a femotosecond laser was employed to investigate occupied and unoccupied electronic states of molecule/metal interfaces. Here we selected two specific examples of interfaces, benzenethiols on Cu(111) and hexa-cata-hexabenzocoronene (HBC) on Cu(111), which are important model systems for an organic / electrode interface of organic semiconductor devices. Although the same copper substrate was used for all the experiments, the nature of interfaces was strongly affected by the interaction between molecular adlayers and metal substrate.
Our TPPE measurements on two benzenthiol species, thiophenol and p-fluorothiophenol, on Cu(111) focus on the role of adsorbates in shifting surface polarization and effecting surface electron confinement. As the coverage of each molecule increases, their photoemission-measured work functions exhibit nearly identical behavior up to 0.4-0.5 ML, at which point their behavior diverges; this behavior can be fit to an interfacial bond model for the surface dipole. In addition, our results show the emergence of an interfacial electronic state 0.1-0.2 eV below the Fermi level. This electronic state is attributed to quantum-mechanical-confinement shifting of the Cu(111) surface state by the molecular adsorbates.
Another TPPE study of ours was carried out on an organic semiconductor, HBC, deposited on Cu(111). An increase of HBC coverage continuously shifts the vacuum level of the Cu substrate until a coverage of 2 ML is reached. In the same range of coverage, the Shockley state and the image potential states are quenched while new unoccupied states develop. The momentum- and polarization-resolved photoemission spectra reveal that the new states are originated from a Cu image state. Electron localization is discussed with respect to the structural evolution of HBC.
For the case (2), nonlinear optical scanning microscopy was designed to study third-harmonic generation (THG) from micron- scale graphene crystals on glass substrate. The polarization-, thickness-, and orientation- dependence of THG signals from the graphene were measured and compared to theoretical prediction using the nonlinear optical slab model of Bloembergen and Pershan. The results revealed in-plane isotropy and out-of-plane anisotropy of the THG signals and sub-quadratic dependence of the layer number. Due to the strong THG signal, background-free imaging of graphene crystal was carried out. This result implies the potential application of THG for imaging graphene on arbitrary substrates.

description: Dynamical Ensemble Equivalence between hydrodynamic dissipative equations and suitable time-reversible dynamical systems has been investigated in a class of dynamical systems for turbulence. The reversible dynamics is obtained from the original dissipative equations by imposing a global constraint. We find that, by increasing the input energy, the system changes from an equilibrium state to a non-equilibrium stationary state in which an energy cascade, with the same statistical properties of the original system, is clearly detected.

description: Smartphones and tablets are increasingly ubiquitous, and many users rely on multiple mobile devices to accommodate work, personal, and geographic mobility needs. Pervasive access to always-on mobile computing has created new security and privacy concerns for mobile devices that often force users to carry multiple devices to meet those needs. The volume and popularity of mobile devices has commingled hardware and software design, and created tightly vertically integrated platforms that lock users into a single, vendor controlled ecosystem. My thesis is that lightweight mechanisms can be added to commodity operating systems to enable multiple virtual phones or tablets to run at the same time on a physical smartphone or tablet device, and to enable apps from multiple mobile platforms, such as iOS and Android, to run together on the same physical device, all while maintaining the low-latency and responsiveness expected of modern mobile devices. This dissertation presents two lightweight operating systems mechanisms, virtualization and binary compatibility, that enable multi-persona mobile computing. First, we present Cells, a mobile virtualization architecture enabling multiple virtual phones, or personas, to run simultaneously on the same physical cellphone in a secure and isolated manner. Cells introduces device namespaces that allow apps to run in a virtualized environment while still leveraging native devices such as GPUs to provide accelerated graphics. Second, we present Cycada, an operating system compatibility architecture that runs applications built for different mobile ecosystems, iOS and Android, together on a single Android device. Cycada introduces kernel-level code adaptation and diplomats to simplify binary compatibility support by reusing existing operating system code and unmodified frameworks and libraries. Both Cells and Cycada have been implemented in Android, and can run multiple Android virtual phones, and a mix of iOS and Android apps on the same device with good performance. Because mobile computing has become increasingly important, we also present a new way to teach operating systems in a mobile-centric way that incorporates the concepts of geographic mobility, sensor data acquisition, and resource-constrained design considerations.

description: In this dissertation, we introduce a framework for simulating the dynamics between liquid and thin structures, including the effects of buoyancy, drag, capillary cohesion, dripping, and diffusion. After introducing related works, Part I begins with a discussion on the interactions between Newtonian fluid and fabrics. In this discussion, we treat both the fluid and the fabrics as continuum media; thus, the physical model is built from mixture theory. In Part II, we discuss the interactions between Newtonian fluid and hairs. To have more detailed dynamics, we no longer treat the hairs as continuum media. Instead, we treat them as discrete Kirchhoff rods. To deal with the thin layer of liquid that clings to the hairs, we augment each hair strand with a height field representation, through which we introduce a new reduced-dimensional flow model to solve the motion of liquid along the longitudinal direction of each hair. In addition, we develop a faithful model for the hairs' cohesion induced by surface tension, where a penalty force is applied to simulate the collision and cohesion between hairs. To enable the discrete strands interact with continuum-based, shear-dependent liquid, in Part III, we develop models that account for the volume change of the liquid as it passes through strands and the momentum exchange between the strands and the liquid. Accordingly, we extend the reduced-dimensional flow model to simulate liquid with elastoviscoplastic behavior. Furthermore, we use a constraint-based model to replace the penalty-force model to handle contact, which enables an accurate simulation of the frictional and adhesive effects between wet strands. We also present a principled method to preserve the total momentum of a strand and its surface flow, as well as an analytic plastic flow approach for Herschel-Bulkley fluid that enables stable semi-implicit integration at larger time steps. We demonstrate a wide range of effects, including the challenging animation scenarios involving splashing, wringing, and colliding of wet clothes, as well as flipping of hair, animals shaking, spinning roller brushes from car washes being dunked in water, and intricate hair coalescence effects. For complex liquids, we explore a series of challenging scenarios, including strands interacting with oil paint, mud, cream, melted chocolate, and pasta sauce.
