Automating the management of environmental compliance reporting: Making the complex simple

Automating the management of environmental compliance reporting: Making the complex simple

Date: March 9, 2000
Creator: Perkins, S.
Description: Environmental compliance reporting requirements are notoriously complex. This reporting complexity is compounded by organizational and functional complexity at Rocky Mountain Arsenal (RMA), where the Department of the Army has undertaken a multi billion dollar environmental cleanup action. This site is subject to both fixed and contingent federal, state, and local reporting requirements. Management and operation of the site is characterized by numerous organizational layers, and compliance information is generated by many different contractors and subcontractors. This information must be compiled by various managers and reported to either regulators or Department of the Army offices. The RMA Environmental Compliance Office and top-level management must be assured that these reports are being promptly generated and submitted. With over 1,500 individual reporting requirements forecasted for over the next 11 years, the managerial challenge is immense. To facilitate the collation of data and issuance of compliance reports, an intranet-based database is being developed. This database is designed to be available to all personnel with access to the site's environmental compliance intranet. It presents all applicable reporting requirements in an easily sortable format. Information available for each report includes deadlines, report status, recipients, individuals responsible for report generation, and other relevant data fields. Reports can ...

Rapidity gaps in hard processes at D0

Rapidity gaps in hard processes at D0

Date: September 1, 1996
Creator: Perkins, J.
Description: Latest results on jet production with rapidity gaps at the Fermilab Tevatron Collider are presented. Jet production via color-singlet exchange at high momenta transfer is observed as a class of events with low particle multiplicity (or rapidity gaps) between the two highest transverse energy jets. The particle multiplicity in various regions, and the dependencies on jet pseudorapidity separation and jet transverse energy are studied for these events. Results from two classes of dijet events with one or two forward rapidity gaps are also presented. The topology of these events is consistent with expectations for hard single diffraction and hard double pomeron exchange processes, respectively.

Fast-wave Power Flow Along SOL Field Lines In NSTX nd The Associated Power Deposition Profile Across The SOL In Front Of The Antenna

Fast-wave Power Flow Along SOL Field Lines In NSTX nd The Associated Power Deposition Profile Across The SOL In Front Of The Antenna

Date: June 21, 2013
Creator: Perkins, Roy
Description: Fast-wave heating and current drive efficiencies can be reduced by a number of processes in the vicinity of the antenna and in the scrape off layer (SOL). On NSTX from around 25% to more than 60% of the high-harmonic fast-wave power can be lost to the SOL regions, and a large part of this lost power flows along SOL magnetic field lines and is deposited in bright spirals on the divertor floor and ceiling. We show that field-line mapping matches the location of heat deposition on the lower divertor, albeit with a portion of the heat outside of the predictions. The field-line mapping can then be used to partially reconstruct the profile of lost fast-wave power at the midplane in front of the antenna, and the losses peak close to the last closed flux surface (LCFS) as well as the antenna. This profile suggests a radial standing-wave pattern formed by fast-wave propagation in the SOL, and this hypothesis will be tested on NSTX-U. Advanced RF codes must reproduce these results so that such codes can be used to understand this edge loss and to minimize RF heat deposition and erosion in the divertor region on ITER.

The Impact of a Community College Teacher Education Program on the Success Rate of Minority Teacher Certification Students

The Impact of a Community College Teacher Education Program on the Success Rate of Minority Teacher Certification Students

Date: May 2013
Creator: Perkins, Britine Lynee
Description: The relationship between the mission of community colleges and the increasing teacher shortage has become more transparent as many community colleges have implemented teacher education programs to address community needs, the shortage of qualified teachers, and the lack of diversity among teachers. As the community college's teacher education role has increased, many community colleges have responded by adding associate of arts degrees and certificate programs specific to teacher education to tackle the shortage of teachers and the lack of diversity among teachers in the nation's classrooms. The purpose of this study was to examine the effectiveness of one community college's pre-service teacher education program in transferring minority students to a university teacher education program and the likelihood of the students graduating with both bachelor's degrees and teacher certification. This longitudinal ex post facto causal-comparative mixed methods case study involved tracking a cohort of minority students over a 6-year period. Data were gathered from existing teacher education program records for native and transfer students at one community college and two four-year institutions. Unstructured interviews were conducted with administrators over the community college's program. For data analysis, ?2 and Phi Coefficients were conducted to compare the minority students' university transfer and graduation ...

The Relationship of Anxiety to Critical Thinking

Date: August 1971
Creator: Perkins, Fredda M.
Description: Anxiety increase drive level and will at first lead to an increased level of performance and then, as drive level continues to rise, to a decrease in performance. There seems to be an optimal level condition for best performance. On either side of this point, performance is relatively impaired. However, nothing has been done to explore directly its relationship to critical thinking ability. The purpose of this study was to investigate that relationship.

Expanded Perceptions of Identity in Benjamin Britten's Nocturne, Op. 60

Expanded Perceptions of Identity in Benjamin Britten's Nocturne, Op. 60

Date: May 2008
Creator: Perkins, Anna Grace
Description: A concentrated reading of Benjamin Britten's Nocturne through details of the composer's biography can lead to new perspectives on the composer's identity. The method employed broadens current understandings of Britten's personality and its relationship to the music. After creating a context for this kind of work within Britten scholarship, each chapter explores a specific aspect of Britten's identity through the individual songs of the Nocturne. Chapter 2 focuses on how Britten used genres in a pastoral style to create his own British identity. Chapter 3 concentrates on the complex relationship between Britten's homosexuality and his pacifism. Chapter 4 aims to achieve a deeper understanding of Britten's idealization of innocence. The various aspects of Britten's personality are related to one another in the Conclusion.

Preliminary Survey of Icing Conditions Measured During Routine Transcontinental Airline Operation

Preliminary Survey of Icing Conditions Measured During Routine Transcontinental Airline Operation

Date: December 16, 1952
Creator: Perkins, Porter J.
Description: Icing data collected on routine operations by four DC-4-type aircraft equipped with NACA pressure-type icing-rate meters are presented as preliminary information obtained from a statistical icing data program sponsored by the NACA with the cooperation of many airline companies and the United States Air Force. The program is continuing on a much greater scale to provide large quantities of data from many air routes in the United States and overseas. Areas not covered by established air routes are also being included in the survey. The four aircraft which collected the data presented in this report were operated by United Air Lines over a transcontinental route from January through May, 1951. An analysis of the pressure-type icing-rate meter was satisfactory for collecting statistical data during routine operations. Data obtained on routine flight icing encounters from.these four instrumented aircraft, although insufficient for a conclusive statistical analysis, provide a greater quantity and considerably more realistic information than that obtained from random research flights. A summary of statistical data will be published when the information obtained daring the 1951-52 icing season and that to be obtained during the 1952-53 season can be analyzed and assembled. The 1951-52 data already analyzed indicate that the quantity, ...

Flight Instrument for Measurement of Liquid-Water Content in Clouds at Temperatures Above and Below Freezing

Flight Instrument for Measurement of Liquid-Water Content in Clouds at Temperatures Above and Below Freezing

Date: March 5, 1951
Creator: Perkins, Porter J.
Description: A principle formerly used in an instrument for cloud detection was further investigated to provide a simple and rapid means for measuring the liquid-water content of clouds at temperatures above and below freezing. The instrument consists of a small cylindrical element so operated at high surface temperatures that the impingement of cloud droplets creates a significant drop in the surface temperature. ? The instrument is sensitive to a wide range of liquid-water content and was calibrated at one set of fixed conditions against rotating multicylinder measurements. The limited conditions of the calibration Included an air temperature of 20 F, an air velocity of 175 miles per hour, and a surface temperature in clear air of 475 F. The results obtained from experiments conducted with the instrument indicate that the principle can be used for measurements in clouds at temperatures above and below freezing. Calibrations for ranges of airspeed, air temperature, and air density will be necessary to adapt the Instrument for general flight use.

Icing Frequencies Experienced During Climb and Descent by Fighter-Interceptor Aircraft

Icing Frequencies Experienced During Climb and Descent by Fighter-Interceptor Aircraft

Date: July 1, 1958
Creator: Perkins, Porter J.
Description: Data and analyses are presented on the relative frequencies of occurrence and severity of icing cloud layers encountered by jet aircraft in the climb and descent phases of flights to high altitudes. Fighter-interceptor aircraft operated by the Air Defense Command (USAF) at bases in the Duluth and Seattle areas collected the data with icing meters installed for a l-year period. The project was part of an extensive program conducted by the NACA to collect Icing cloud data for evaluating the icing problem relevant to routine operations. The average frequency of occurrence of icing was found to be about 5 percent of the number of climbs and descents during 1 year of operations The icing encounters were predominantly in the low and middle cloud layers, decreasing above 15,000 feet to practically none above 25,000 feet. The greatest thickness of ice that would accumulate on any aircraft component (as indicated by the accretion on a small object) was measured with the icing meters. The ice thicknesses on a small sensing probe averaged less than 1/32 inch and did not exceed 1/2 inch. Such accumulations are relatively small when compared with those that can form during horizontal flight in icing clouds. The light ...

High density, high magnetic field concepts for compact fusion reactors

High density, high magnetic field concepts for compact fusion reactors

Date: October 11, 1996
Creator: Perkins, L. J.
Description: One rather discouraging feature of our conventional approaches to fusion energy is that they do not appear to lend themselves to a small reactor for developmental purposes. This is in contrast with the normal evolution of a new technology which typically proceeds to a full scale commercial plant via a set of graduated steps. Accordingly` several concepts concerned with dense plasma fusion systems are being studied theoretically and experimentally. A common aspect is that they employ: (a) high to very high plasma densities ({approximately}10{sup 16}cm{sup -3} to {approximately}10{sup 26}cm{sup -3}) and (b) magnetic fields. If they could be shown to be viable at high fusion Q, they could conceivably lead to compact and inexpensive commercial reactors. At least, their compactness suggests that both proof of principle experiments and development costs will be relatively inexpensive compared with the present conventional approaches. In this paper, the following concepts are considered: (1) The staged Z-pinch, (2) Liner implosion of closed-field-line configurations, (3) Magnetic ``fast`` ignition of inertial fusion targets, (4) The continuous flow Z-pinch.

Complexity versus availability for fusion: The potential advantages of inertial fusion energy

Complexity versus availability for fusion: The potential advantages of inertial fusion energy

Date: September 5, 1996
Creator: Perkins, L.J.,
Description: Probably the single largest advantage of the inertial route to fusion energy (IFE) is the perception that its power plant embodiments could achieve acceptable capacity factors. This is a result of its relative simplicity, the decoupling of the driver and reactor chamber, and the potential to employ thick liquid walls. We examine these issues in terms of the complexity, reliability, maintainability and, therefore, availability of both magnetic and inertial fusion power plants and compare these factors with corresponding scheduled and unscheduled outage data from present day fission experience. We stress that, given the simple nature of a fission core, the vast majority of unplanned outages in fission plants are due to failures outside the reactor vessel itself Given we must be prepared for similar outages in the analogous plant external to a fusion power core, this puts severe demands on the reliability required of the fusion core itself. We indicate that such requirements can probably be met for IFE plants. We recommend that this advantage be promoted by performing a quantitative reliability and availability study for a representative IFE power plant and suggest that databases are probably adequate for this task.

Antiproton fast ignition for Inertial Confinement Fusion

Antiproton fast ignition for Inertial Confinement Fusion

Date: October 24, 1997
Creator: Perkins, L.J.
Description: With 180MJ/{micro}g, antiprotons offer the highest stored energy per unit mass of any known entity. We investigate the use of antiprotons to promote fast ignition in an ICF capsule and seek high gains with only modest compression of the main fuel. Unlike standard fast ignition where the ignition energy is supplied by an energetic, short pulse laser, the energy here is supplied through the ionization energy deposited when antiprotons annihilate at the center of a compressed fuel capsule. In the first of two candidate fast ignition schemes, the antiproton package is delivered by a low energy external ion beam. In the second, ''autocatalytic'' scheme, the antiprotons are pre-emplaced at the center of the capsule prior to compression. In both schemes, we estimate that {approximately}3x10{sup 13} antiprotons are required to initiate fast ignition in a typical ICF capsule and show that incorporation of a thin, heavy metal shell is desirable to enhance energy deposition in the igniter zone. In addition to obviating the need for a second energetic fast laser and vulnerable final optics, this scheme would achieve central without reliance on laser channeling through halo plasma or houlrahm debris. However, in addition to the unknowns involved in the storage and ...

AFREET: HUMAN-INSPIRED SPATIO-SPECTRAL FEATURE CONSTRUCTION FOR IMAGE CLASSIFICATION WITH SUPPORT VECTOR MACHINES

AFREET: HUMAN-INSPIRED SPATIO-SPECTRAL FEATURE CONSTRUCTION FOR IMAGE CLASSIFICATION WITH SUPPORT VECTOR MACHINES

Date: February 1, 2001
Creator: PERKINS, S. & HARVEY, N.
Description: The authors examine the task of pixel-by-pixel classification of the multispectral and grayscale images typically found in remote-sensing and medical applications. Simple machine learning techniques have long been applied to remote-sensed image classification, but almost always using purely spectral information about each pixel. Humans can often outperform these systems, and make extensive use of spatial context to make classification decisions. They present AFREET: an SVM-based learning system which attempts to automatically construct and refine spatio-spectral features in a somewhat human-inspired fashion. Comparisons with traditionally used machine learning techniques show that AFREET achieves significantly higher performance. The use of spatial context is particularly useful for medical imagery, where multispectral images are still rare.

GENIE: A HYBRID GENETIC ALGORITHM FOR FEATURE CLASSIFICATION IN MULTI-SPECTRAL IMAGES

Date: December 1, 2000
Creator: PERKINS, S. & AL, ET
Description: We consider the problem of pixel-by-pixel classification of a multi-spectral image using supervised learning. Conventional supervised classification techniques such as maximum likelihood classification and less conventional ones such as neural networks, typically base such classifications solely on the spectral components of each pixel. It is easy to see why the color of a pixel provides a nice, bounded, fixed dimensional space in which these classifiers work well. It is often the case however, that spectral information alone is not sufficient to correctly classify a pixel. Maybe spatial neighborhood information is required as well. Or may be the raw spectral components do not themselves make for easy classification, but some arithmetic combination of them would. In either of these cases we have the problem of selecting suitable spatial, spectral or spatio-spectral features that allow the classifier to do its job well. The number of all possible such features is extremely large. How can we select a suitable subset? We have developed GENIE, a hybrid learning system that combines a genetic algorithm that searches a space of image processing operations for a set that can produce suitable feature planes, and a more conventional classifier which uses those feature planes to output a ...

A New Approach for the Permanent Disposal of Long Lived Fission Waste

A New Approach for the Permanent Disposal of Long Lived Fission Waste

Date: March 27, 2007
Creator: Perkins, L J
Description: Nuclear fission can meet humanity's disparate requirements for carbon-free energy throughout this century and for millennia to come - not only for electricity but also as a source of hydrogen for transportation fuels and a heat source for desalination. However, most countries are not pursuing fission as an option for future energy and global climate needs. One paramount reason is diminished public acceptance over concerns of waste disposal. We would also add 'fuel resources' as a major future concern, because fission is not sustainable in the long term with the present 'once-through' fuel that utilizes less than 1% of the mined uranium and consigns its fertile potential to a permanent waste repository. Accordingly, global scale fission will become attainable (i.e., doable) if and when an integrated solution to this overall 'fuel-cycle' problem is realized. It is the back-end of the fuel cycle - i.e., the need for permanent storage of spent fuel and high-level waste - that has become the focus of much of the criticism. In particular, the construction and implementation of permanent waste repositories such as Yucca Mountain is becoming increasingly problematic from a financial and political perspective. The major shortcoming of these conventional repositories is that they ...
