Tree Reduction And Debris From Mastication Of Utah Juniper Alter The Soil Climate In Sagebrush Steppe, Kert R. Young, Bruce A. Roundy, Dennis L. Eggett

Articles

Juniper (Juniperus spp.) trees are masticated to reduce canopy fuel loads and the potential for crown fire. We determined the effects of tree reduction and soil cover in the forms of tree mounds and masticated debris on hourly soil water potential and soil temperature at 1–30 cm soil depth. Measurements were made in masticated and untreated areas at three sites in the western Utah portion of the Great Basin. Cumulative seasonal-response variables included wet days (>−1.5 MPa), degree days (>0 °C), and wet degree days (>−1.5 MPa and >0 °C). Masticated areas had 27 more wet …

Leveraging Depolarization To Increase The Link Reliability For Wireless Sensors Operating In Hyper-Rayleigh Environments, Jeff Frolik, Vit Sipal, David J. Edwards

Articles

Wireless communications within enclosed environments such as aircraft and vehicles have been shown to experience fading with statistics that are worse than Rayleigh. Motivated by low-cost, low-complexity systems (e.g., wireless sensors) that may be deployed in such environments, this work explores the benefits of polarization diversity using very large data sets collected over a small area and over the 5-6 GHz band. The results also demonstrate that antennas capable of capturing depolarized signal components can significantly mitigate the harshest of fading environments.

Feed‐In Tariff Design For Domestic Scale Grid‐Connected Pv Systems Using High Resolution Household Electricity Demand Data, Lacour Ayompe, Aidan Duffy

Articles

The advent of large samples of smart metering data allows policymakers to design Feed‐in Tariffs which are more targeted and efficient. This paper presents a methodology which uses these data to design FITs for domestic scale gridconnected PV systems in Ireland. A sample of 2,551 household electricity demand data collected at ½‐hourly intervals, electricity output from a 2.82 kWp PV system over the same time interval as well as PV system costs and electricity tariffs were used to determine the required FIT to make it worthwhile for the households to invest in the PV system. The methodology shows that it …

Was That A Song?, Donald J. Herzog

Articles

Jazz constantly spins off new possibilities, seizing on fusion with rock, new rhythms from Brazil and then "world music," astringent harmonies and atonal combinations from "new" music or twentieth-century "classical," and more. [...]jazz musicians have been relaxing constraints since the beginning. Piano players might keep "comping" or accompanying the soloists with well-chosen chords, but they might roam free or just stop playing.\n Again you can wonder how much of this was deliberately plotted out before the trio hit the stage, how much developed on the spot.

Washington Trust Law's Extreme Makeover: Blending With The Uniform Trust Code And Taking Reform Further With Innovations In Notice, Situs, And Representation, Karen E. Boxx, Katie S. Groblewski

Articles

Washington trust laws were comprehensively revised in 2011 and 2013, resulting in the integration of concepts from the Uniform Trust Code and the addition of some novel provisions. This article discusses in depth the evolution of Washington law regarding the duties to inform and report, the situs of a trust, and representation of interested parties. In addition, this article discusses other UTC provisions that were integrated into Washington statutes and gives an explanation of any departures from UTC language and prior Washington law.

Footwear Antennas For Body Area Telemetry, Domenico Gaetano, Patrick Mcevoy, Max Ammann, Jacinta Browne, Louise Keating, Frances Horgan

Articles

Antennas designed to link footwear sensors within body centric networks are introduced with two small UWB antennas, one directional and another quasi-omnidirectional. The radiating characteristics are evaluated for three positions on a sample sports shoe using a detailed simulation model and measurements with a homogenous foot phantom. Antenna performance is assessed for resilience to close proximity loading by the footwear materials and the phantom foot.

Small Wind Turbines In Turbulent (Urban) Environments: A Consideration Of Normal And Weibull Distributions For Power Prediction, Keith Sunderland, Thomas Woolmington, Jonathan Blackledge, Michael Conlon

Articles

The urban terrain and the associated morphological complexities therein, present significant challenges for the deployment of small wind turbines. In particular, a considerable amount of uncertainty is attributable to the lack of understanding concerning how turbulence within urban environments affects turbine productivity. Current wind turbine power output measurements (particularly for small/micro wind turbines) are based on an average wind speed over an observation period; with limited accountability of the variability of wind speed within the observation time frame. This paper however, presents two models that can instead accurately consider such wind speed variation and how it affects the turbine, based …

Albert Camus At 100 : A Mediterranean Son Of France, Eamon Maher

Articles

THIS YEAR marks the centenary of the birth of one of the world's finest writers, the French-Algerian Albert Camus (1913-1960). When his father, a pied-noir farm labourer died fighting in the French army during the First World War, Camus' mother, Catherine, was forced to work as a cleaner to provide for her two sons. The younger one, Albert, demonstrated academic talent from an early age and managed to continue in education due to the interest taken in him by two inspirational teachers, Louis Germain and the well-known philosopher, Jean Grenier. He was also awarded scholarships, without which he could not …

Synthesis Of Orthogonally Protected 1,2-Diaminopropanoic Acids By Ring-Opening Of 3-Unsubstituted N-Activated Aziridine 2-Carboxylates With Para-Methoxybenzylamine: A Study Of The Regioselectivity Of The Reaction, Fintan Kelleher, Keith O'Brien

Articles

Orthogonally protected 1,2-diaminopropanoic acids (DAPs) have been synthesised in good yields by the ring-opening of 3-unsubstituted N-activated aziridine 2-carboxylates with para-methoxybenzylamine. The choice of both the N-activating group and ester alkyl group had a significant influence on the ratio of attack at the a or b positions of the aziridine. However, the regiochemical outcome is not predictable.

Defining Privacy And Utility In Data Sets, Felix T. Wu

Articles

Is it possible to release useful data while preserving the privacy of the individuals whose information is in the database? This question has been the subject of considerable controversy, particularly in the wake of well-publicized instances in which researchers showed how to re-identify individuals in supposedly anonymous data. Some have argued that privacy and utility are fundamentally incompatible, while others have suggested that simple steps can be taken to achieve both simultaneously. Both sides have looked to the computer science literature for support.

What the existing debate has overlooked, however, is that the relationship between privacy and utility depends crucially …

New Challenges For Strategy Development In Irish Higher Education Institutions., Deirdre Lillis, Marion Lynch

Articles

Strategic planning has become an integral part of the management of higher education institutions worldwide. The experiences of all but one of the Republic of Ireland’s 21 Universities and Institutes of Technology with strategic planning are explored from 2000-2010. At the starting point in 2000 only two Institutions had a documented strategic plan. Ten years later all had undergone one or more iterations of strategic planning. Qualitative research methods were used including document analysis of n=42 strategic plans, n=12 institutional review reports and n=26 interviews with senior managers with responsibility for strategic planning. The paper considers whether the strategic planning …

A Comparative Cytotoxic Evaluation Of Acrylamide And Diacetone Acrylamide To Investigate Their Suitability For Holographic Photopolymer Formulations, Dervil Cody, Alan Casey, Izabela Naydenova, Emilia Mihaylova

Articles

The comparative cytotoxic evaluation of two monomers Diacetone Acrylamide (DA) and Acrylamide (AA), used in holographic photopolymer formulations, is reported. Two normal cell lines were used: BEAS-2B and HaCaT. Cellular viability was assessed using the MTT assay for three different exposure times. A difference of two orders of magnitude is observed in the Lethal Dose (LD50) concentrations of the two monomers. Diacetone Acrylamide exhibits a significantly lower toxicity profile in comparison to Acrylamide at all exposure times. This result justifies the replacement of Acrylamide with Diacetone Acrylamide in the photopolymer formulation, with the view to reducing occupational hazard risks for …

A Construction That Produces Wallis-Type Formulas, Joshua M. Fitzhugh, David L. Farnsworth

Articles

Generalizations of the geometric construction that repeatedly attaches rectangles to a square, originally given by Myer- son, are presented. The initial square is replaced with a rectangle, and also the dimensionality of the construction is increased. By selecting values for the various parameters, such as the lengths of the sides of the original rectangle or rectangular box in dimensions more than two and their relationships to the size of the attached rectangles or rectangular boxes, some interesting formulas are found. Examples are Wallis-type infinite-product formulas for the areas of p-circles with p > 1.

In this article we investigate the connection between a family of com-plemented subspaces of a Banach space having a holomorphic basis, and being holomorphically complemented.

The "Nixon Sabotage": The Political Origins Of The Equal Protection Challenge To The Voting Rights Act, Danieli Evans

Articles

Critics of the Voting Rights Act argue that the anti-discrimination law requires states to engage in unconstitutional discrimination, as state decisionmakers must be conscious of race in order to ensure that voting policies do not weaken minority representation. This argument relies on the idea that subjective racial motivation is the essence of unconstitutional discrimination (even if benevolent, or to promote racial inclusion). The conventional understanding among constitutional scholars is that this “search for the bigoted decisionmaker” developed in employment and housing discrimination decisions between 1976 and 1979. Previous accounts have not recognized the role that the 1971 school desegregation decision …

Maximising Value Of Electrical Networks For Wave Energy Converter Arrays, Fergus Sharkey, Elva Bannon, Michael Conlon, Kevin Gaughan

Articles

Currently there are the beginnings of a commercial wave energy industry and the ultimate ambition will be to deploy Wave Energy Converters (WECs) in arrays, or wave farms, in a similar fashion to offshore wind. These arrays will require electrical networks to collect and export the generated electrical power to shore and onto the electrical grid. For large scale wind farms the inter-array and export electrical networks can represent more than 20% of the project’s capital expenditure. Submarine power cables account for a large proportion of this cost. The same is expected to be the same for WEC arrays.

Dual Circularly-Polarized Patch Antenna Using Even And Odd Feed-Line Modes, Adam Narbudowicz, Xiulong Bao, Max Ammann

Articles

This paper proposes a new patch antenna with dual circularly polarized capability at 2.575 GHz. The design exploits the even and odd modes in a coplanar waveguide transmission line and enables simultaneous right- and left-handed circular polarization, with two individual excitation ports. A patch antenna is fed by multimode transmission line and the advantages and disadvantages are discussed. A prototyped antenna realized up to 20 dB isolation between ports with S21 < -10dB bandwidth of 87 MHz. Realized gains for the two modes of operation are 5.77 and 7.23 dBic. The proposed structure is compact and easy to manufacture.

Computing The Grounded Semantics In All The Subgraphs Of An Argumentation Framework: An Empirical Evaluation, Pierpaolo Dondio

Articles

Given an argumentation framework – with a finite set of arguments and the attack relation identifying the graph – we study how the grounded labelling of a generic argument a varies in all the subgraphs of . Since this is an intractable problem of above-polynomial complexity, we present two non-naïve algorithms to find the set of all the subgraphs where the grounded semantic assigns to argument a specific label . We report the results of a series of empirical tests over graphs of increasing complexity. The value of researching the above problem is two-fold. First, knowing how an argument behaves …

Overstating The Satisfaction Of Lawyers, David L. Chambers

Articles

Recent literature commonly reports US lawyers as disheartened and discontented, but more than two dozen statistically based studies report that the great majority of lawyers put themselves on the satisfied side of scales of job satisfaction. The claim of this article is that, in three ways, these statistically based studies convey an overly rosy impression of lawyers’ attitudes: first, that many of those who put themselves above midpoints on satisfaction scales are barely more positive than negative about their careers and often have profound ambivalence about their work; second, that surveys conducted at a single point in time necessarily fail …

Single-Mode Tunable Laser Emission In The Single-Exciton Regime From Colloidal Nanocrystals, Christos Grivas, Chunyong Li, Peristera Andreakou, Pengfei Wang, Ming Ding, Gilberto Brambilla, Liberato Manna, Pavlos Lagoudakis

Articles

Whispering-gallery-mode resonators have been extensively used in conjunction with different materials for the development of a variety of photonic devices. Among the latter, hybrid structures, consisting of dielectric microspheres and colloidal core/shell semiconductor nanocrystals as gain media, have attracted interest for the development of microlasers and studies of cavity quantum electrodynamic effects. Here we demonstrate single-exciton, single-mode, spectrally tuned lasing from ensembles of optical antenna-designed, colloidal core/shell CdSe/CdS quantum rods deposited on silica microspheres. We obtain singleexciton emission by capitalizing on the band structure of the specific core/shell architecture that strongly localizes holes in the core, and the two-dimensional quantum …

Revisiting Walter Macken’S Connemara, Eamon Maher

Articles

As a writer, Macken was attuned to the menacing depths that lay behind the physical exterior: the infertile bogland that makes farming problematic, the harsh character of the inhabitants, their callous treatment of one another, their superstitious religiosity and frustrated love affairs. I read most of Macken’s novels as a teenager and enjoyed them enormously. It is a shame that there is little or no critical attention now paid to someone who had such a successful career as a novelist, playwright, actor and director. Even the publication by his son Ultan of a biography, Walter Macken: Dreams on Paper, by …

Articles

Background

Acrylamide as a possible carcinogen is known to form in heated carbohydrate-rich food such as potato chips. In this study, the effect of three potato varieties (Agria, Sante and Savalan) and two blanching conditions ((75˚C for 9 min and 83˚C for 2.5 min) on the concentration of precursors and acrylamide reduction in potato chips was investigated.

Results

Results revealed that potato variety and blanching time-temperature ere important parameters for acrylamide formation in potato chips. Acrylamide content in Sante variety potatoes, which contained the highest amount of reducing sugars, was found to be the highest (8825μg/kg). However, Savalan, containing …

Development Of A Jobs Database For Tracking Knowledge And Skills Expectations In The Workplace, Esa M. Rantanen, Christopher Claeys, Daniel Roder

Articles

The primary objective of college education in applied disciplines is that it is relevant to the expectations for new professionals entering the labor market. Academic institutions should therefore pay close attention to the ever-changing skills and knowledge expectations in the labor market. These trends are not easy to track, however. Surveys of new professionals about their experiences in their first jobs or surveys of employers about their experiences with new hires suffer from low response rates, nonresponse bias, and the one-time nature of survey research. A better way to track labor market trends is to continually analyze human factors job …

Uncertainty In Population Estimates For Endangered Animals And Improving The Recovery Process, Dale D. Goble

Articles

United States recovery plans contain biological information for a species listed under the Endangered Species Act and specify recovery criteria to provide basis for species recovery. The objective of our study was to evaluate whether recovery plans provide uncertainty (e.g., variance) with estimates of population size. We reviewed all finalized recovery plans for listed terrestrial vertebrate species to record the following data: (1) if a current population size was given, (2) if a measure of uncertainty or variance was associated with current estimates of population size and (3) if population size was stipulated for recovery. We found that 59% of …
