Electromagnetic design optimization of planar integrated power passive modules

Integration of passive components, such as the planar L-C-T (inductor-capacitor-transformer) technology has been the subject of research over the last few years and has been proven to be viable at high frequencies. In this paper the electromagnetic (EM) design of planar L-L-C-T structures is considered. With a comprehensive, yet simple loss model including nonlinear excitation and skin- and proximity-effects, it is possible to optimize a planar integrated structure for a given set of equivalent electrical circuit parameters. The use of simple design and loss models allow the rapid evaluation of designs that will facilitate the development of an optimization process. Both the available materials and the constructional limitations are included in the optimization process as they, together with the structural losses, determine the realizable module designs. The question as to 'what is optimum? ' arises, and the different possible criteria for optimization are evaluated. The optimization process, although generic, is considered for a 1MHz, 500 W resonant prototype.
Energy management strategies use short‐term water consumption forecasting to minimize cost of pumping operations

By moving from a reactive (consumption‐following) to a proactive operating strategy using short‐term consumption forecasting (STCF), utilities can save millions of dollars in energy costs. Accurate forecasting techniques and tools are required to realize these cost savings. Short‐term consumption forecasting systems at four water utilities as well as developed prototype systems at five water utilities were studied. Various forecasting methods were also studied and accuracy benchmarked. These nine utilities comprise numerous climate zones and varied customer demographics throughout North America. Electric utility experience with short‐term load forecasting is also presented. Observations and lessons learned are presented. Further recommendations will be published by the Awwa Research Foundation in a future report.

Sliding mode for equivalent force control in real‐time substructure testing

The equivalent force control method uses feedback control to replace a mathematical iteration to solve the nonlinear difference equation in a real‐time substructure test with an implicit integration method. The commonly used PID controller as a candidate of equivalent force control has only limited robustness for nonlinear systems. For real‐time substructure testing with nonlinear specimens, the sliding mode control is proposed as the outer‐loop controller of the equivalent force control. The design approach and implementation issues are discussed analytically. The effects of key parameters of sliding mode controller on the performance of equivalent force control are demonstrated through numerical simulation. The real‐time as well as pseudodynamic substructure tests are carried out with a linear elastic spring and a nonlinear buckling restrained brace as experimental substructures. The effectiveness of the sliding mode control is verified by these tests. Copyright © 2014 John Wiley & Sons, Ltd.
Energy control for long lifetime photovoltaic ac module inverter

Photovoltaic power generation is spreading all around the globe with increasing support from the public and governments. Among the obstacles yet to overcome are higher cell efficiency, lower cost, and longer lifetime. The latter is the focus of the research presented here as it provides an alternative photovoltaic ac module inverter with long lifetime. Four commercial inverters analyzed in our laboratory contained electrolytic capacitors whose lifetimes are limited to 12000 hours. In the proposed solution these components are obviated by using an energy control scheme that stores all the energy fluctuation in the dc-link polypropylene capacitor. The energy control strategy has been applied in a prototype power conditioning unit that comprises a phase-shift full-bridge dc-ac-dc converter connected in series with a current source inverter. The grid current magnitude is controlled using a proportional derivative compensator that maintains the average value of the dc-link capacitor at a voltage level of 475V, while allowing oscillations with a peak value of 125V. Simultaneously, a pulse-width-modulation integrated circuit controller maintains a steady dc voltage at the photovoltaic panel's terminals, hence enhancing the performance of the maximum power point tracking algorithm. The sinusoidal shape of the current injection is attained using current-mode-control. It is shown that the converter operates at high efficiency and that the energy fluctuation is absorbed at the dc-link capacitor. In addition, it is shown that the perturb and observe maximum power point tracking algorithm performs well over a day of variable irradiance conditions.
CRASH ATTRIBUTES THAT INFLUENCE THE SEVERITY OF ROLLOVER CRASHES. IN: OCCUPANT AND VEHICLE RESPONSES IN ROLLOVERS

Rollover crashes continue to be a growing source of motor vehicle injuries and deaths in the United States. This chapter on crash attributes that influence the severity of rollover crashes is from a comprehensive textbook on occupant and vehicle responses in rollovers. The authors of this chapter examine statistics from the NASS/CDS, a national sample of crashes in the United States. A condition for entry in the database is that one light vehicle must be damaged sufficiently that it is towed from the crash scene. The authors evaluated rollover crash severity metrics and then recommend additional data elements to assist in determining rollover severity. For belt occupants and unbelted ejected occupants in single vehicle crashes, the number of roof impacts is an appropriate severity indicator. Additional severity measures such as the delta-V for the pre-rollover crash event are required in addition to the rollover severity measures. For crashes that involve another vehicle prior to rollover, the injury risks are about 1.5 times higher than for single vehicle rollovers. Risks of severe or fatal injuries in rollovers may be increased by collisions with fixed vertical objects such as trees and walls during the process of the rollover. The authors conclude that additional data elements may be required to identify these cases and provide added predictors for the crash severity measurement.

A compact, high-performance laser-pumped rubidium frequency standard

We present the realisation of a compact and high-performance Rubidium atomic frequency standard under development for space applications. The clock comprises a compact frequency-stabilised diode laser head for optical pumping of a lamp-removed industrial Rb clock module, in order to exploit the advantages of laser optical pumping for optimised short- term stability. We obtain typical signal contrasts around 20%, resulting in an estimated signal-to-noise limit for the short- term stability of about 1middot10 -12 tau -1/2 . Modification of the buffer- gas filling in the clock resonance cell allows to reduce instabilities arising from the AC Stark effect and temperature variations, that limit the clock stability on longer timescales. The clock stability of the realised demonstrator breadboard was measured to be better than 4middot10 -12 tau -1/2 up to 10 4 seconds, already meeting the specifications for the GALILEO Rb clocks. Further optimisation should allow the realisation of a laser-pumped Rb clock reaching 3middot10 -13 tau -1/2 in a compact device (<1.51, 1.5 kg, 15 W). Such compact and high- performance clocks can find their applications in telecommunications, science missions, and future generations of satellite navigation systems (GALILEO, GPS).

HUMAN HEAD IMPACT RESPONSE. EXPERIMENTAL DATA AND ANALYTICAL SIMULATIONS

The dynamic response of the human head is investigated using experimental data and analytical simulations. The head acceleration response is characterized from experiments on seated human cadavers subjected to frontal, occipital, and side head impacts. Acceleration time histories at the head vertex and at the front/occiput/side of the head are presented for measured force time histories and impact velocities. Response results from a detailed multi-degree of freedom model, incorporating inertial and constitutive properties of the head-neck system, are also presented. Finally, head injury criteria are discussed on the basis of experiments and model analysis. /Author/TRRL/
Classifying controllers by activities : An exploratory study

The goal of this paper is to discern variables (triggers) that affect a controller’s role in an organisation. Using survey data, groups of controllers are distinguished based on coherent combinations of activities. We find that controllers either operate as so-called ‘information adapters’ or ‘watchmen’. Whether someone is bound to be an information adapter or watchman is mainly affected by personality traits and someone’s experience in finance and accounting. This research can help to shape the controller function in organisations in such a way that the ensuing activities are manageable and do not contradict one another. Another contribution of this research is that an empirically informed framework that overcomes various conceptual disagreements in the literature is generated that can be used for the future testing of hypotheses.

Thermoelectric properties, efficiency and thermal expansion of ZrNiSn half-Heusler by first-principles calculations

In this work, we try to understand the experimental thermoelectric (TE) properties of a ZrNiSn sample with DFT and semiclassical transport calculations using SCAN functional. SCAN and mBJ provide the same band gap Eg of ∼0.54 eV. This Eg is found to be inadequate to explain the experimental data. The better explanation of experimental Seebeck coefficient S is done by considering Eg of 0.18 eV which suggests the non-stoichiometry and/or disorder in the sample. In the calculation of S and other TE properties temperature dependence on chemical potential is included. In order to look for the possible enhanced TE properties obtainable in ZrNiSn with Eg of ∼0.54 eV, power factor and optimal carrier concentrations are calculated. The optimal electron and hole concentrations required to attain highest power factors are ∼7.6 × 1019 cm−3 and ∼1.5 × 1021 cm−3, respectively. The maximum figure of merit ZT calculated at 1200 K for n-type and p-type ZrNiSn are ∼0.5 and ∼0.6, respectively. The % efficiency obtained for n-type ZrNiSn is ∼4.2% while for p-type ZrNiSn is ∼5.1%. The ZT are expected to be further enhanced to ∼1.1 (n-type) and ∼1.2 (p-type) at 1200 K by doping with heavy elements for thermal conductivity reduction. The phonon properties are also studied by calculating dispersion, total and partial density of states. The calculated Debye temperature of 382 K is in good agreement with experimental value of 398 K. The thermal expansion behaviour in ZrNiSn is studied under quasi-harmonic approximation. The average linear thermal expansion coefficient αave(T) of ∼7.8 × 10−6 K−1 calculated in our work is quite close to the experimental values. The calculated linear thermal expansion coefficient will be useful in designing the thermoelectric generators for high temperature applications.
Improving Robustness of Task Oriented Dialog Systems

Task oriented language understanding in dialog systems is often modeled using intents (task of a query) and slots (parameters for that task). Intent detection and slot tagging are, in turn, modeled using sentence classification and word tagging techniques respectively. Similar to adversarial attack problems with computer vision models discussed in existing literature, these intent-slot tagging models are often over-sensitive to small variations in input -- predicting different and often incorrect labels when small changes are made to a query, thus reducing their accuracy and reliability. However, evaluating a model's robustness to these changes is harder for language since words are discrete and an automated change (e.g. adding `noise') to a query sometimes changes the meaning and thus labels of a query. In this paper, we first describe how to create an adversarial test set to measure the robustness of these models. Furthermore, we introduce and adapt adversarial training methods as well as data augmentation using back-translation to mitigate these issues. Our experiments show that both techniques improve the robustness of the system substantially and can be combined to yield the best results.
Decentralized Planning for Autonomous Agents Cooperating in Complex Missions

Abstract : Planning for autonomous vehicles remains an important and challenging research topic. This thesis focuses on decentralized planning for autonomous agents performing complex missions. These types of missions often involve a set of tasks, each representing a component of the mission. Task planning algorithms may be used as part of the mission planner to assign agents to tasks; however, the decentralized task assignment problem becomes increasingly difficult when there exists coupling in the task set. Coupling may be in the form of assignment relationships, where the value of a task is condition on whether or not another task has been assigned, or temporal relationships where the value of a task is conditioned on when it is performed relative to other tasks. In this work, task coupling is treated as a constraint, and a task planning framework is introduced which is specifically designed to ensure that all coupled constraints are satisfied by the assignment. The new algorithm is developed from a baseline Consensus-Based Bundle Algorithm (CBBA) and is called Coupled- Constraint CBBA, or CCBBA. The new algorithm is compared to the baseline in a complex mission simulation and is found to outperform the baseline by up to a factor of 3 with respect to assignment score. A separate extension to CBBA is also developed for satisfying refuel constraints in the task assignment process, and the technique is verified through numerical simulation. Lastly, this thesis examines the autonomous search problem where a fleet of sensorequipped agents are deployed to find objects of interest in an environment. A local search strategy developed for the Onboard Planning System for UAVs in Support of Expeditionary Reconnaissance and Surveillance (OPS-USERS) program is described which is a receding horizon optimization technique.
A Solution to the Problem of Too Many Instruments in Dynamic Panel Data GMM

The well-known problem of too many instruments in dynamic panel data GMM is dealt with in detail in Roodman (2009, Oxford Bull. Econ. Statist.). The present paper goes one step further by providing a solution to this problem: factorisation of the standard instrument set is shown to be a valid transformation for ensuring consistency of GMM. Monte Carlo simulations show that this new estimation technique outperforms other possible transformations by having a lower bias and RMSE as well as greater robustness of overidentifying restrictions. The researcher's choice of a particular transformation can be replaced by a data-driven statistical decision.
A concrete Atlantis : U.S. industrial building and European modern architecture, 1900-1925

"Let us listen to the counsels of American engineers. But let us beware of American architects! " declared Le Corbusier, who like other European architects of his time believed that he saw in the work of American industrial builders a model of the way architecture should develop. It was a vision of an ideal world, a "concrete Atlantis" made up of daylight factories and grain elevators.In a book that suggests how good Modern was before it went wrong, Reyner Banham details the European discovery of this concrete Atlantis and examines a number of striking architectural instances where aspects of the International Style are anticipated by US industrial buildings.
Design and Implementation of a Three-Link Brachiation Robot with Optimal Control Based Trajectory Tracking Controller

This paper reports the design and implementation of a three-link brachiation robot. The robot is able to travel along horizontal monkey bars using continuous arm swings. We build a full order dynamics model for the robot and formulate each cycle of robot swing motion as an optimal control problem. The iterative Linear Quadratic Regulator (iLQR) algorithm is used to find the optimal control strategy during one swing. We select suitable robot design parameters by comparing the cost of robot motion generated by the iLQR algorithm for different robot designs. In particular, using this approach we show the importance of having a body link and low inertia arms for efficient brachiation. Further, we propose a trajectory tracking controller that combines a cascaded PID controller and an input-output linearization controller to enable the robot to track desired trajectory precisely and reject external disturbance during brachiation. Experiments on the simulated robot and the real robot demonstrate that the robot can robustly swing between monkey bars with same or different spacing of handholds.
Microbial risk assessment for recreational use of the Kranji Reservoir, Singapore

The Public Utilities Board of Singapore is responsible for management of the Kranji drinking water reservoir and wishes to open the reservoir for recreational water use as part of their "Active, Beautiful, and Clean Waters Programme". A field campaign was conducted at the Kranji Reservoir to determine the microbial water and sediment quality of the reservoir for use in a model that predicts the risk of gastrointestinal illness due to recreational use of the reservoir. Water samples were collected at seven locations throughout the reservoir and sediment samples were collected at two locations located near the shore. The samples were then analyzed for Enterococci concentrations using a most probable number method. The measured geometric mean concentrations found during the field campaign were 13.3 Enterococci colony forming units (CFU) per 100 ml water and 1400 Enterococci CFU per gram sediment. Based on the strengths and weaknesses of available statistics-based risk models, a model by Wiedenmann was chosen based on the flexibility of the model and the quality of the underlying epidemiological study. Using the model, no-observed-adverse-effect-level guideline concentrations of 25 Enterococci CFU per 100 ml for swimming, 51 Enterococci CFU per 100 ml for kayaking and 860 Enterococci CFU per gram sediment for wading were calculated. Based on all available bacterial measurements of the Kranji Reservoir, an interim geometric mean guideline of 25 Enterococci CFU per 100 ml water and 860 Enterococci CFU per gram sediment is suggested. Single-sample maximums for a monitoring program should be set to 96 Enterococci CFU per 100 ml water and 2,500 Enterococci CFU per gram sediment. These guidelines should be applied to the area of the reservoir open to recreation, which should be restricted to the northem main section of the reservoir. Entry and exit from the reservoir and wading should be restricted to a smaller area of shoreline until more sediment samples are taken to determine safe entry and exit areas. Final geometric mean and single-sample maximum guidelines should be based on a study of the pathogen-to-indicator-bacteria ratios in the Kranji Reservoir.
