Moo
No full textmoo is a collection of calling poems. To those long gone and those not yet born. To those in hard places around the globe. To those lost and struggling. To those who must fend for themselves. To hope. Always. To hope. Paula C. Lowe roots the poetry of moo in a rural earth of gritty survival, says author Molly Best Tinsley. These are poems of extraordinary focus, from the \u27neck of a kitten\u27 to the \u27spit of a warlord\u27s speech.\u27 Minnesota poet Sharon Chmielarz says, From Pipestone to Wounded Knee, from Midwest to Middle East, from Afghanistan to the lobotomized in an American hospital, in Paula C. Lowe\u27s moo poems ...every window (is) unlocked (to) let wind inside. It\u27s a pleasure to read muscled, rhythmic, disciplined yet flowing stanzas and lines. O! Lest I forget, Slim Moon is one of the best moon poems in a decade. And, at last, a new take on Danny Boy : o dani. Got milk? Get moo. Rosi Loval of Oslo says, Lowe captures ancestry in our cells. Selected poems are translated into Norwegian to honor immigrants in the 1800\u27s. And Missouri poet James O. Ferrugia says, this is storytelling born of the country. In moo, you will find yourself and your people and your times and your past and your earth and your nature and your hope. Whether you read a lot or a little, these poems will make you laugh and cry and wonder who you are. Poet Paula C. Lowe lives out of town three hours north of LA. Her poems appear in dozens of literary journals, and several anthologies. She holds a graduate degree from the University of Washington and has authored half a dozen non-fiction books. An Iowa farmer\u27s daughter, she spent years in the Northwest, Bahama Islands and the central coast of California.https://aura.antioch.edu/stubooks/1025/thumbnail.jp
Stable organic solar cells employing MoO(3)-doped copper phthalocyanine as buffer layer
No full textA stable organic solar cell with structure of ITO/buffer/donor/acceptor/cathode is presented. A thin layer (5 nm) of MoO(3)-doped CuPc is adopted as the buffer in CuPc/C(60) organic heterojunction photovoltaic (PV) solar cells, resulting in two times longer lifetime. The surface morphology of buffer layer plays a decisive role in improving the stability. Crown Copyright (C) 2011 Published by Elsevier B. V. All rights reserved
MOO for the conceptual design of structures
No full textThesis: S.M. in Building Technology, Massachusetts Institute of Technology, Department of Architecture, 2016.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 107-113).Using computational tools, fast and accurate predictions of building performance are increasingly possible. In parallel, the expectations of a high-performance building have been rising in contemporary architecture, as designers must synthesize many inputs to arrive at a design that fulfills a wide range of requirements. Despite the clear need for assistance in prioritizing and managing different design objectives, advances in performance analysis have not commonly translated into guidance in early stage design, as the limits of the traditional design process and a separation of disciplines have relegated performance feedback to later phases. In order to facilitate better design on a holistic level, researchers in related areas have developed multiobjective optimization (MOO), which is a methodology intended for navigating complex design spaces while managing and prioritizing multiple objectives. However, after reviewing existing design optimization research and considering current usage of optimization in AEC practice, a number of clear research questions arise: How can conceptual, architectural design problems be formulated and solved using MOO in a way that generates diverse, high-performing solutions? What is the best way for the designers of buildings and structures to interact with MOO problems? Finally, how does the use of MOO in the conceptual phase affect design possibilities and outcomes? This thesis addresses these key research questions, along with a number of secondary questions, through a combination of design case studies, tool development, user experience testing, and historical analysis. First, it presents a conceptual framework for implementing MOO within architectural parametric design tools in flexible, interactive way. Next, it shows the outcomes of a conceptual design exercise in which participants are given increasing access to performance feedback. Finally, through the application of MOO to three long span roof case studies, it demonstrates how MOO can lead to diverse, high-performing results that are difficult to generate through other means, before introducing a new way in which multi-objective techniques can be used to analyze historical structures. Together, these contributions encourage more widespread and effective use of multi-objective optimization in conceptual design, leading to better performing buildings and structures without overly constraining creative, innovative designers. Key words: multi-objective optimization, design space exploration, conceptual design, design tradeoffs, interactive design tools, structural design, embodied and operational energy.by Nathan C.

Spectrosc. 146, 274 (1991).Author Institution: Moscow State University, 117234 Moscow Russia.Absorption spectrum of MoO has been obtained in a plasma originated from a pulse electric discharge through mixture of with and Ar or through . The discharge tube was placed into a cavity of a dye laser. Different sorts of dyes were used to cover spectral region from 550-850 nm. Emission spectrum of the dye laser served as a background were photographed by grating spectrograph with high resolution. The time delay between dye laser and discharge pulses (about 50 ms.) was used to record the MoO spectrum of the best quality. Numerous bands were registered in the absorption spectrum. Four of the more easily discernible open red bands were selected. Three of this bands coincide with the known bands of MoO [1, 2]. By analogy with isovalent molecules (CrO, WO) this bands were assigned to (O-O) bands of transition. For the first time the rotational analysis of these bands was performed. Two sets of constants for state were calculated: . The constants obtained for state coincide with that in [2]. Analysis of other bands is in progress
On the Strengths of Pure Evolutionary Algorithms in Generating Adversarial Examples
No full textDeep learning (DL) models are known to be highly accurate, yet vulnerable to adversarial examples. While earlier research focused on generating adversarial examples using whitebox strategies, later research focused on black-box strategies, as models often are not accessible to external attackers. Prior studies showed that black-box approaches based on approximate gradient descent algorithms combined with meta-heuristic search (i.e., the BMI-FGSM algorithm) outperform previously proposed white- and black-box strategies. In this paper, we propose a novel black-box approach purely based on differential evolution (DE), i.e., without using any gradient approximation method. In particular, we propose two variants of a customized DE with customized variation operators: (1) a single-objective (Pixel-SOO) variant generating attacks that fool DL models, and (2) a multi-objective variant (Pixel-MOO) that also minimizes the number of changes in generated attacks. Our preliminary study on five canonical image classification models shows that Pixel-SOO and Pixel-MOO are more effective than the state-of-the-art BMI-FGSM in generating adversarial attacks. Furthermore, Pixel-SOO is faster than Pixel-MOO, while the latter produces subtler attacks than its single-objective variant.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Multimedia ComputingSoftware Engineerin
What Lies beyond the Pareto Front? A Survey on Decision-Support Methods for Multi-Objective Optimization
No full textWe present a review that unifies decision-support methods for exploring the solutions produced by multi-objective optimization (MOO) algorithms. As MOO is applied to solve diverse problems, approaches for analyzing the trade-offs offered by MOO algorithms are scattered across fields. We provide an overview of the advances on this topic, including methods for visualization, mining the solution set, and uncertainty exploration as well as emerging research directions, including interactivity, explainability, and ethics. We synthesize these methods drawing from different fields of research to build a unified approach, independent of the application. Our goals are to reduce the entry barrier for researchers and practitioners on using MOO algorithms and to provide novel research directions.Interactive IntelligencePolicy Analysi
Li<sub>2</sub> MoO<sub>4</sub> -based composite ceramics fabricated from temperature- and atmosphere-sensitive MnZn ferrite at room temperature
No full textAbstractThe first magnetic ceramic composites manufactured, using the room-temperature densification method are reported. The samples were prepared at room temperature using Li₂MoO₄ as a matrix and MnZn ferrite with loading levels of 10–30 vol-% followed by postprocessing at 120°C. The method utilizes the water solubility of the dielectric Li₂MoO₄ and compression pressure instead of high temperatures typical of conventional solid-state sintering. Hence, composite manufacturing using temperature- and atmosphere-sensitive materials is possible without special conditions. This was demonstrated with MnZn ferrite, which is prone to oxidation when heat treated in air. Samples manufactured with room-temperature densification showed no signs of reactivity during processing, whereas reference samples sintered at 685°C suffered from oxidation and formation of an additional reaction phase. The densities achieved with different loading levels of MnZn ferrite with both methods were very similar. Measurements up to 1 GHz showed relatively high values of relative permittivity (21.7 at 1 GHz) and permeability (2.6 at 1 GHz) with 30 vol-% loading of MnZn ferrite in the samples manufactured by room-temperature densification. In addition, pre-granulation is proposed to improve the processability of the composite powders in room-temperature densification.Abstract

Torture Laid Bare
No full textTorture, while internationally sanctioned, is not well-defined. This paper sets out a Minimal English definition of the crime of 'torture' in international law. The four elements of torture are: (1) infliction of severe pain and suffering (2) acting with intent (3) for a purpose (4) by the state. The connection between intention and outcome is considered in the light of presumptions. I then briefly consider the concept of 'lawful sanctions' and the UN Standard Minimum Rules that apply to the treatment of prisoners to establish a baseline against which allegations of torture can be measured. Finally, I argue that current regimes of British benefit sanctions, whereby social welfare payments are stopped, may in some cases constitute torture. This argument considers the effects of sanctions and the discourses and ideologies attached to social welfare claimants.© 2017.

Design of a Highly Efficient 20 kW Inductive Power Transfer System with Improved Misalignment Performance
No full textDue to the urgent desire for a fast, convenient, and efficient battery charging technology for electric vehicle (EV) users, extensive research has been conducted into the design of high-power inductive power transfer (IPT) systems. However, there are few studies that formulate the design as a multiobjective optimization (MOO) research question considering both the aligned and misaligned performances and validate the optimal results in a full-scale prototype. This article presents a comprehensive MOO design guideline for highly efficient IPT systems and demonstrates it by a highly efficient 20-kW IPT system with the dc-dc efficiency of 97.2% at the aligned condition and 94.1% at 150-mm lateral misalignment. This achievement is a leading power conversion efficiency metric compared to IPT EV charging systems disseminated in today's literature. Herein, a general analytical method is proposed to compare the performances of different compensation circuits in terms of the maximum efficiency, voltage/current stresses, and misalignment tolerance. An MOO method is proposed to find the optimal design of the charging pads, taking the aligned/misaligned efficiency and area/gravimetric power density as the objectives. Finally, a prototype is built according to the MOO results. The charging pad dimension and total weight, including the housing material, are 516∗552∗60 mm3/25 kg for the transmitter and 514∗562∗60 mm3/21 kg for the receiver. Correspondingly, the gravimetric, volumetric, and area power density are 0.435 kW/kg, 581 kW/m3, and 69.1 kW/m2, respectively. The measured efficiency agrees with the anticipated value derived from the given analytical models.DC systems, Energy conversion & Storag
Dynamic and interactive re-formulation of multi-objective optimization problems for conceptual architectural design exploration
No full textSimulation-Based Multi-Objective Optimization (SBMOO) methods are being increasingly used in conceptual architectural design. They mostly focus on the solving, rather than the re-formulation, of a Multi-Objective Optimization (MOO) problem. However, Optimization Problem Re-Formulation (Re-OPF) is necessary for treating ill-defined conceptual architectural design as an iterative exploration process. The paper proposes an innovative SBMOO method which builds in a dynamic and interactive Re-OPF phase. This Re-OPF phase, as the main novelty of the proposed method, aims at achieving a realistic MOO model (i.e., a parametric geometry-simulation model which includes important objectives, constraints, and design variables). The proposed method is applied to the conceptual design of a top-daylighting system, focusing on divergent concept generation. The integration of software tools Grasshopper and modeFRONTIER is adopted to support this application. The main finding from this application is that the proposed method can help to achieve quantitatively better and qualitatively more diverse Pareto solutions.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Design Informatic
