description: The bandwidth requirement for each link on a network-on-chip (NoC) may differ based on topology and traffic properties of the IP cores. Available bandwidth on an  asynchronous NoC link will also vary depending on the wire length between sender and receiver. This work explores the benefit to NoC performance, area, and energy when this property is used to optimize bandwidth on specific links based on its bandwidth required by a target SoC design.  Three asynchronous routers were designed for implementing of asynchronous NoCs.   Simple routing scheme and single-flit packet format lead to performance- and area-efficient router designs. Their performance was evaluated in consideration of link wire  delay.  Comprehensive analysis of pipeline latch insertion in asynchronous communication links is performed in regard to link bandwidth. Optimal placement of pipeline latch for maximizing benefit to increase of bandwidth is described.  Specific methods are proposed for performance, area and energy optimization, respectively. Performance optimization is achieved by increasing bandwidth of high  trafficked and high utilized links in an NoC, as inserting pipeline latches in those links. Through decrease of bandwidth of links with low traffic and low utilization by  halving data-path width, reduction of wire area of an NoC is accomplished. Energy optimization is performed using wide spacing between wires in links with high energy consumption.  An analytical model for asynchronous link bandwidth estimation is presented. It is utilized to deploy NoC optimization methods as identifying adequate links for each optimization method.  Energy and latency characteristics of an asynchronous NoC are compared to a similarly-designed synchronous NoC. The results indicate that the asynchronous network has lower energy, and link-specific bandwidth optimization has improved NoC performance.  Evaluation of proposed optimization methods by employing to an asynchronous NoC shows achievements of performance enhancement, wire area reduction and wire energy saving.

description: Chapter 1 examines the stratigraphic architecture of the lower straight cliffs formation across the southwestern portion of the Kaiparowits Plateau in southern Utah. To determine the controls affecting deposition of marginal marine deposits, seven stratigraphic sections (each ~90-100m) and 729 paleocurrents were measured along a 20 km transect (A-A'). This study divides the lower Straight Cliffs Formation into four depositional units (DU), representing distinct and genetically-related depositional environments: prograding shoreface parasequences (DU-1), tidally influenced fluvial channels and estuaries (DU-2), a transitional sequence of shoreface deposits through fluvial deposits (DU-3), and downstream accreting fluvial deposits (DU-4). This interpretation represents both minor and more significant revisions to previous interpretations of this succession, and highlights the need for high-resolution stratigraphic studies to fully understand depositional compexity in this and similar settings. Earth scientists often use images to communicate scientific concepts, and they commonly provide cues establishing the scale of features shown ('hammer for scale,' etc). How effective are these kinds of scaling cues? Chapter 2 examines the effect of scaling cures and interactivity on the ability of earth scientists to extract information from 2 2D image. To evaluate both scaling cues and interactivity, a visualization test was created in which participants were asked to estimate the size of several boxes shown in outcrop photos. All test subjects first viewed a static image, followed by an interactive (gigapan) image of the same outcrop; two different outcrops of different sizes were used. Participants (test group =63, further testing in progress) represent a range of experience and education levels. Results show that scaling estimates are more difficult for larger/more distant outcrops. Scaling cues can also become a distractor for viewers of any experience level or background. It is important to realize that viewers internalize scaling cues differently, so different types of cues may help some viewers more than others. Also it appears that incorporating interactivity can increase accuracy, due to the ability to customize views that best fits an individual's learning style and internal sense of problem solving, The results of this study contain numerous educational implications for the application of scale and interactivity.

description: The higher expression level of p53 in epithelial adipose tissue (EAT) has previously been reported in atherosclerosis. Since we hypothesized that the expression of p53 is modulated by Sirt1, the aim of this study was to determine the expression levels of Sirt1 and p53 and to investigate their correlation to apoptosis in EAT of patients with coronary artery disease (CAD). Thirty-five patients with more than 50 % stenosis in at least one of the main coronary arteries were considered as CAD group while 29 patients with no clinical signs of atherosclerosis who underwent open-heart surgery for valve replacement were classified as control group. EAT biopsy samples were collected from all participants during surgery. Sirt1, p53, Bax, and Bcl 2 gene expression levels were determined in EAT by qRT-PCR and Western blotting was carried out to assess Sirt1 and p53 protein levels. Hematoxylin and eosin staining was used for histopathological analysis. mRNA and protein levels of Sirt1 in EAT were significantly lower in patients with CAD compared with control group, whereas CAD patients showed greater p53 gene and protein expressions. In addition, inverse correlations were observed between Sirt1 and p53 at both mRNA and protein levels. The Bax and ratio of Bax/Bcl-2 gene expressions were higher in CAD group, but no difference was observed in Bcl-2 expression. Histopathological analysis showed apoptotic bodies and infiltrated immune cells in EAT of CAD group. Our results suggest that the Sirt1-p53 axis may involve in atherosclerosis by promotion of apoptosis.

description: The objective of this dissertation is to estimate possible leakage pathways such as abandoned wells and fault zones in the deep subsurface for CO2 storage using inverse analysis. Leakage pathways through a cap rock may cause CO2 to migrate into the layers above cap rock. An inverse analysis using iTOUGH2 was applied to estimate possible leakage pathways using pressure anomalies in the overlying formation induced by brine and/or CO2 leaks. Prior to applying inverse analysis, sensitivity analysis and forward modeling were conducted. In addition, an inverse model was developed for single-phase flow and it was applied to the leakage pathway estimation in a brine/CO2 system. Migration of brine/CO2 through the leakage pathway was simulated in the generic homogeneous and heterogeneous domains. The increased pressure gradient due to CO2 injection continuously induced brine leaks through the leakage pathway. Capillary pressure was induced by the migration of CO2 along the leakage pathway saturated by brine. Pressure anomalies due to capillary pressures were propagated to the entire overlying formation. The sensitivity analysis was focused on how the hydrogeological properties affect the pressure signals at monitoring wells. Parameter estimation using the iTOUGH2 model was applied to detect locations of leakage pathways in homogeneous and heterogeneous model domains. For homogeneous models, the parameterization of uncertain permeability in an overlying formation could improve location estimation accuracy. Residual analysis illustrated that pressure anomalies in the overlying formation induced by leaks are critical information for the leakage pathway estimation. For heterogeneous models, the calibration of renormalized permeability values could reduce systematic modeling errors and should improve the leakage pathway location estimation accuracy. The weighting factors significantly influenced the accuracy of the leakage pathway estimation. The developed inverse model was applied to estimate the leakage pathway in a brine/CO2 system using pressure anomalies induced by only brine leaks. To estimate a possible leakage pathway, the developed inverse model calibrated each integrated parameter (of both cross-sectional area and vertical hydraulic conductivity) of initial guesses of the leakage pathway. This application can provide warning before the CO2 leaks, and will be useful in mitigating the risk of CO2 leaks.

Quantitative EMG

description: Electromyography (EMG) is the record of the electrical activity from muscle fiber membranes. This invaluable clinical tool in neurology aids in the diagnosis and monitoring of disease affecting muscle and nerve. Routine clinical EMG studies rely on the experience of the physician to analyze the data in a qualitative manner. Quantitative EMG (QEMG) refers to a number of techniques that measure various aspects of the EMG signal and result in statistical data. These techniques are becoming broader in scope, more automated and increasingly available on EMG machines. However, QEMG studies have challenges in a number of operational parameters from the engineering perspective but may not accurately fit from the physiologic and pathologic perspectives, and a number of these issues have not been investigated in a systematic way.  Here we present a number of studies aimed at validating and improving clinical usability of QEMG. First, we compare three QEMG algorithms available on EMG machines for use in the clinic, a study not performed previously. We determined that two algorithms yield similar results with minimal user intervention, while the third requires considerable expert review of the results and which are less robust than with the first two. Second, we show that among available sizes of intramuscular needle electrodes the smaller diameter electrode yields data comparable to the larger diameter electrode for clinical QEMG. Third, we show that any needle electrode position along the longitudinal axis of the muscle with respect to the distribution of neuromuscular junctions within the muscle is acceptable for clinical QEMG studies. Fourth, we investigate and find that high-pass filtering is not an effective means of extracting more sensitive information from the EMG signals. Finally, we determine that at each position of the electrode within the muscle, 10 s worth of data collection balances the need to collect sufficient data with the possibility of degrading the signal due to subtle physiologic movements. The results of these efforts are a better understanding of the practical limits of the QEMG algorithms and how operational parameters can be optimized for more accurate statistics, more rapid data acquisition, and greater patient tolerability.

description: Upper limb amputees desire an artificial arm that allows for multiple degrees of freedom of control over the movements of the prosthesis, coupled with direct sensory  feedback. The goal of this work was to assess if it is feasible to interface artificial limbs to severed nerves of human upper limb amputees. Longitudinal intrafascicular electrodes were interfaced to severed nerve stumps of long-term human amputees. Initial studies conducted for two days following electrode implantation showed that it is possible to provide discrete, unitary, painless, graded sensations of touch, joint movement and position referred to the missing limb. Amputees were able to generate and control motor nerve activity uniquely associated with the missing limb movements. Longer term studies conducted for a period of up to 4 weeks showed recorded motor nerve activity and elicited sensations remained stable and there was no significant change in the stimulation parameters. Finally, amputees were able to control a modified Utah Artificial Arm.  Results of our studies show that it is possible to interface an artificial limb to the severed nerves of upper limb amputees. Further work is required to refine the hardware which can be eventually incorporated into the artificial arm, allowing the amputees to wear the  prosthesis and more precisely execute movements related to real life activities of daily living.

description: The emetic action of nicotine and lobeline was studied in cats and dogs.  The minimal uniformly effective emetic doses were found to be 1.5 mg/kg I.M. nicotine bitartrate and 0.5 mg/kg I.M. lobeline sulfate.  In terms of the alkaloid base, the dose-response relationship coincided, for practical purposes, at all dose levels studies.  Sixty-six cats and ten dogs were used to establish the locus of the emetic action of the alkaloids.  It was found, in cats, the agents stimulated two different sites of action, namely, a peripheral locus ( or loci) as well as the CT-zone.  Therefore, in order to eliminate vomiting response to nicotine and lobeline in cats, it was necessary to combine the following procedures:  spinal visceral deafferentation, vagotomy, and CT-zone ablation.  The combination of these lesions was accomplished either by peripheral nerve sections in combination with CT-zone ablation or by a broad medullary lesion with destroyed both the CT-zone and incoming visceral afferents.  The dogs, CT-zone ablation alone sufficed to protect animals against the emetic effect of nicotine and lobeline.  The implication of these results in discussed in light of investigations of species variations previously reported in this field.  Anti-emetic drug studies were also included in the present investigation.  Tetraethylammonium (TEA) was effective in preventing emesis in response to nicotine in both cats and dogs, but it was effective only against lobeline in cats.  Hexamethonium (C6) protected both species against uniformly effective emetic doses of nicotine and lobeline.  Neither atropine nor chlorpromazine was found significantly to protect animal of either species against the emetic action of nicotine and lobeline.

description: Living systems have fairly high concentration of ions, and as a result they conduct electricity, and therefore may impair the quality of magnetic resonance imaging.

The conductivity effect in magnetic resonance imaging only change the signal intensity and does not cause blurring.
Development and Applications of 3D Ultra-short Echo Time MRI with Rosette k-Space Pattern

Publisher: name: Purdue University Graduate School
Year: 2022
Subjects: Biomedical imaging

description:
 Magnetic resonance imaging (MRI) plays an important role in providing structural information, aiding in disease diagnosis, probing neuron activities, and etc. Sampling k-space, which is the Fourier transform of the image, is a necessary step in MRI scans. The most widely used k-space sampling strategy is the Cartesian trajectories. However, novel non-Cartesian trajectories are flexible and efficient in k-space sampling, permit shorter echo time, and are insensitive to motion artifacts. The non-Cartesian k-space patterns include radial, spiral, concentric rings, rosette, and etc. Some protons restricted by the chemical environment, or other nuclei because of their nature, have short transverse relaxation times (T2). Ultra-short echo time (UTE) and zero echo time (ZTE) modalities are the promising techniques to capture the rapid decaying signals directly. The common k-space pattern for UTE and ZTE applications is the three-dimensional radial acquisition, which allows a center-out trajectory. Rosette k-space trajectory, which also allows center-out sampling, is a potential candidate for UTE purposes. In addition, it acquires more samples in the peripheral k-space for better spatial resolution, and is more incoherent to stand image quality upon undersampling than radial. However, the rosette trajectories have not yet been applied in UTE. In this study, a 3D rosette k-space trajectory designed for UTE acquisition is developed. In addition, a rosette-based magnetic resonance spectroscopic imaging (MRSI) is also developed to measure metabolites with short echo time. A comparison between 3D rosette and 3D radial UTE sequences, based on both phantom and in vivo scans, was performed to test the performance of the novel sequence. In addition, the 3D rosette UTE sequence was also applied in 1) myelin bilayer imaging, 2) brain iron content mapping, 3) cartilage image by sodium MRI, and 4) phosphorus MRSI. In summary, the 3D rosette k-space trajectory performs better than radial, in terms of point spread function (PSF), signal-to-noise ratio (SNR), and ability to provide structural details. Furthermore, the applications have demonstrated that 3D rosette UTE sequence is able to capture fast decaying signals.

description: Pool boiling of ethanol and Cu-nanofluid was investigated on bare and novel supersonic nanoblown polymer nanofiber nanotextured copper surface. Significant improvement in early ONB (2°C reduction), CHF (23.5%), and BHTC (~2–2.5 times) were achieved in nanotextured surface than bare one. Boiling of nanofluids led to the degradation of ONB and BHTC, with an increase in CHF by 16.7%. Synergistic effect of nanofluid boiling on nanotextured surface led to remarkable enhancement of CHF (44%), BHTC (>2.5 times), and ONB (3°C reduction). The nanofluid and nanotexture aided in ONB and CHF via enhancing nucleation sites, liquid overheating, bubble chopping, and surface wettability.
Modern Art Galleries in Paris and Berlin c.1890-1933: types, policies and modes of display
Creators: name: Gee, Malcolm
Publisher: name: Journal for Art Market Studies
Year: 2018

description: This article discusses the character of commercial galleries engaged in the promotion of contemporary art in Paris and Berlin during a crucial period, which began with the consolidation of exhibition networks diffusing ‘independent’ art’ at the end of the nineteenth century, and ended with the economic crisis of the 1930s and the Nazi takeover of power in Germany. It examines the types of spaces occupied by these galleries, and their location; the modes of presentation adopted for different types of work, both in terms of hanging and framing and exhibition organisation; and the relation between these matters and the commercial position and practices of the dealers involved. It discusses the evolution of these over the period, and differences and similarities between the situation in the two centres. It concludes with an assessment of the general balance that modern art dealers sustained – with varying degrees of emphasis – between well-established strategies for valorising their products, and newer ones  influenced by contemporary design.

description: The ability to walk is considered an essential motor function for normal human locomotion and transportation. Healthy ambulation is required of relatively all persons on a daily basis, and can be detrimentally affected by an array of different gait disorders. Following a diagnosis, traditional rehabilitative techniques often require the attention of a trained specialist, in addition to expensive instrumentation and training devices. Previous research has been performed regarding the use of insole mounted sensors to detect and quantify gait abnormalities with a comparable rate of accuracy to established systems. Sensory feedback derived from the gait data can be a versatile tool for use alongside established rehabilitative methods, with the potential to act as a standalone technique.   This thesis presents the continuing research into the usage and implementation of force sensitive resistor (FSR) based insoles, with respect to the development of a portable and intuitive feedback device for use in clinical gait modification. The new system design, titled the Adaptive Real-Time Instrumentation System for Tread Imbalance Correction, or ARTISTIC, incorporates a wireless insole system that can transmit gait data wirelessly via a Bluetooth connection. An Android mobile smartphone application, or app, was developed to receive the gait data, and provide the user with different forms of sensory feedback in order to modify their gait. Subjects were tested using each of the feedback methods to determine the efficacy of the ARTISTIC system in modulating their gait away from normal. As a result of the testing, it was determined that visual feedback resulted in a statistically significant (p < 0.05) change in gait ratio for all 12 human subjects. It is anticipated that further improvements will be made, to address suggestions provided by the test subjects as well as to strengthen alternative forms of feedback, such  as audible and vibrotactile cues.
Art Trade Palaces – Galleries of art dealers as architectural task and their reception in Munich around 1900

description: The structural development of commercial galleries and, more generally, of commercially used spaces for the presentation of art works as a historical architectural challenge in the first place should become an integral part of our perception. When the magazine Die Kunst spoke of “Art Dealer Palaces” in 1913, a prime example was Munich.  This article will aim at reconstructing a multi-layered image through historical sources, in particular contemporary articles and reviews from architecture magazines or art journals. In fact, buildings and interiors of art dealers were passionately discussed during this period, and in some cases were even regarded as highly controversial. Several case studies will illustrate the extent to  which the individual elements of presentation – wall, floor, ceiling, light, furniture, artworks and their frames were subject to a thorough revision in 1900, and the extent to which the interior design of commercially used exhibition spaces not only matched the staging concepts of museums and the Secessions, but were in fact closely linked to the idea of the museum reform movement and even established a modern private exhibition practice. While the article captures trends and peculiarities that in turn may allow conclusions to be drawn for the history of exhibition strategy in general, there is a need for more in-depth research of this neglected subject.

Subjects: Demographic
Questionnaire

description: The purpose of this study was to survey the breast-feeding practices in a rural community, and propose a relationship between certain demographic variables and length of the breast-feeding experience.  A fairly homogenous sample of 55 women from the Toole returned the questionnaire.  Two hypotheses were supported by the frequency data and chi-square analysis.  These are: 1) there is an association between the total amount of education a woman had and the length of time she breast-fed her infant, and 2) the less formal and infant received the longer the time of breast-feeding.  A relationship could not be proposed between length of breast-feeding and the variables of age, race, religion, economic status, marital status, previous breast-feeding.  The data either did not provide adequate variation for analysis or did not support an existing relationship, Overwhelmingly, women who responded found breast-feeding enjoyable and received adequate support during the breast-feeding time.

Head-Mounted Display

description: The adoption of Augmented Reality (AR) technology has increased over the years. AR enhances various activities for consumers and businesses, particularly in industrial contexts. The threedimensional virtual experience is realized by the usage of Head-Mounted Displays (HMD). These devices provide access to sensitive data and services. Thus, secure and usable authentication schemes are essential to control access to the HMD and the stored data as well as schemes to authenticate to the services one wants to use with the AR device.We conducted a systematic literature review on knowledge-based authentication schemes for AR HMD. 31 different schemes were identified. These schemes were assessed regarding various aspects including the type of AR HMD, the type of secret, howusers input their secret, aswell as usability and security aspects. We discuss gaps for future work.

Arbeitszufriedenheit

description: Im Rahmen einer empirischen Studie im Auftrag der Gewerkschaft Erziehung und Wissenschaften Niedersachsen haben insgesamt 2.869 Lehrerinnen und Lehrer ein Jahr lang von Ostern 2015 bis Ostern 2016 ihre Arbeitszeiten zeitnah und minutengenau in einem speziell entwickelten Zeiterfassungstool für schulische Lehrtätigkeiten eingetragen. Auf diese Weise wurde erstmalig im großen Umfang die Arbeitszeit von Lehrkräften systematisch in Niedersachsen erfasst, statt auf Schätzverfahren zurückgreifen zu müssen. Darauf aufbauend haben 2.108 Lehrkräfte auch umfassend Auskunft gegeben über ihre Arbeitssituation und ihre Arbeitsbelastung an öffentlichen Schulen Niedersachsens. Erhebungszeitraum war 19. Februar bis 7. März 2016. Auf Grundlage des arbeitswissenschaftlichen Belastungs-Beanspruchungs-Modells wurde die psychi-sche Belastung und Beanspruchung von Lehrkräften aus (21 - 23) standardisierten Lehrtätigkeiten, aus schulspezifischen Besonderheiten und aus der individuell aufgewendeten Arbeitszeit ermittelt. Neben den bereits in der Arbeitszeitstudie erprobten Instrumenten wurden die Qualität der Arbeitsbedingungen mit dem DGB-Index Gute Arbeit und die Arbeitsbezogenen Verhaltens- und Erlebensmuster (AVEM) mit dem von Schaarschmidt u.a. etablierten Instrumentarium erfasst und mit Vergleichsgruppen verglichen.  Lehrkräfte in Niedersachsen bewerten ihre Arbeitsbedingungen sehr viel ungünstiger als vergleichbare Berufsgruppen, sind aber zugleich auch deutlich zufriedener mit ihrer Arbeit als vergleichbare Beschäftigte. Dieses scheinbare Paradox erklärt sich aus einer (meist) hohen intrinsischen Arbeitsmotivation, einer subjektiv (häufig) positiv bewerteten Ressourcenverfügbarkeit und Arbeitsplatzsicherheit auf der einen und hohen Belastungen in einer Reihe von Arbeitsaspekten auf der anderen Seite. Gleichzeitig sind Arbeitgeberbindung sowie Veränderungs- und Verbesserungsbereitschaft hoch. Neben Befunden zu überlangen Arbeitszeiten und einer hohen Arbeitsintensität werden weitere Befunde vorgelegt zu einzelnen schulischen Tätigkeiten (Tätigkeitsmodell), zu schulspezifischen Anforderungen (wie Ganztag, Inklusion, Dokumentationspflichten, Lärm, mangelnden Erholzeiten und dem sozialen Miteinander) sowie zu arbeitsbezogenen Verhaltens- und Erlebensmustern (AVEM). Die differenzierte Auswertung von sechs Schulformen (drei repräsentativ, drei nicht-repräsentativ) mündet in einem Abschlusskapitel mit schulformübergreifenden Herausforderungen und Gestaltungsbedarfen der spezifischen Arbeitsbelastung von Lehrkräften.

description: This dissertation aims to investigate the role of development banks in financing economic growth in Latin America throughout the 20th century. Two study cases are examined: Nacional Financiera (NAFINSA) in Mexico and the Banco Nacional de Desenvolvimento Econômico e Social (BNDES) in Brazil. We use a comparative- historical approach to address similarities and differences between Brazil and Mexico in using financing to spur economic growth. In so doing, we expect to draw useful lessons for policy-makers. The dissertation consists of five sections. The introduction addresses the motive of this dissertation and outlines its approach and structure, and then closes with a necessary background discussion of what development banking is. Section 2 gives a brief historical review of the early progenitors of current development banks. Sections 3 and 4 constitute the bulk of the dissertation. They respectively investigate NAFINSA in Mexico and the BNDES in Brazil. The bulk of each section is a careful historical investigation of the structures and practices of each bank, including in particular how they changed over time. Each of the two sections concludes with a short discussion of implications suggested by that case study. The final brief section 5 of the thesis is a combination of the suggested implications for development banking in Latin America from the two case studies.
Development of an airborne pollution measurement system

description: The Sky-scan Atmospheric Monitoring Instrument (SAMI) consists of a low pro-fi le, autonomous unmanned aerial vehicle (UAV) that provides a platform for remotely  sampling airborne contaminants in real-time over large distances. In this manner, the SAMI may be used to acquire pollutant concentration at various altitudes, relevant, for example, to smokestack emissions, and in high-risk locations where conditions hazardous to humans may exist. The SAMI system employs an innovative miniaturized pollution measurement device that captures discrete gas samples at programmed  intervals during flight and records the corresponding pollutant concentration using an on-board data logger. The pollution measurement device integrates seamlessly with the body of the UAV and directly interfaces with the autopilot hardware/software.  The pollution measurement device draws/expels gas into/out of the sampling chamber by taking advantage of the pressure drop that naturally occurs over the surface of the aircraft. This eliminates the need for an external pump, thereby aff ording signifi cant weight and cost savings. The present thesis documents the response characteristics of the SAMI system and demonstrates the functionality of the system for the specifi c pollutant carbon monoxide (CO). The potential application is real-time monitoring of air pollution dispersion due to automobile traffic.

description: Percutaneous osseointegrated prosthetics are a promising limb prosthetic alternative for amputees. Similar to other percutaneous devices that have permanent residence in host tissue, their success is dependent on an impassable attachment between skin and the device. An incomplete attachment greatly increases risk of infection and subsequent device removal. A common failure mechanism of percutaneous devices is the epidermis migrating internally, called "epidermal downgrowth," creating a pocket between the skin and the device. This pocket serves as an access point for microorganisms, contributing to infection and device failure. Thus, there is a need to improve the skin integration with the percutaneous device such that microbial access and infection is prevented.  This first portion of this dissertation work sought to investigate infection vulnerability of porous titanium and smooth titanium percutaneous implants with subcutaneous flanges. In this work, a more relevant small animal model of percutaneous device infection was established. It was demonstrated that porous surfaces significantly decreased risk of infection of percutaneous implants. However, due to epidermal downgrowth in the majority of implants, there was an absence of skin integration with the percutaneous component, thus contributing to increased infection susceptibility and device failure.
A collective approach to harness idle resources of end nodes

description: We propose a collective approach for harnessing the idle resources (cpu, storage, and bandwidth) of nodes (e.g., home desktops) distributed across the Internet. Instead  of a purely peer-to-peer (P2P) approach, we organize participating nodes to act collectively using collective managers (CMs). Participating nodes provide idle  resources to CMs, which unify these resources to run meaningful distributed services for external clients. We do not assume altruistic users or employ a barter-based  incentive model; instead, participating nodes provide resources to CMs for long durations and are compensated in proportion to their contribution.  In this dissertation we discuss the challenges faced by collective systems, present a design that addresses these challenges, and study the effect of selfish nodes. We believe that the collective service model is a useful alternative to the dominant pure P2P and centralized work queue models. It provides more effective utilization of idle resources, has a more meaningful economic model, and is better suited for building legal and commercial distributed services.  We demonstrate the value of our work by building two distributed services using the collective approach. These services are a collective content distribution service  and a collective data backup service.

description: Stories and narratives have an important role in the development of human relationships, particularly in the development of our relationships to the natural world. The types of story told about the nonhuman world can greatly influence the ways in which humans interact with that world. All too often, those stories have encouraged the creation of a divide between and within the human and nonhuman worlds, a divide that then permits humans to mistreat and degrade various communities in both the nonhuman and human worlds. This work explores the stories that have been and are told about a particular place, the pinyon-juniper ecosystem of the American Southwest. By exploring three particular narratives related to that place-the scientifically founded story, the culturally based story, and the resource-driven story-and the corresponding actions that have derived from those stories, we might be able to better understand how the stories we tell affect our relationship to the nonhuman world and so work to create new, more responsible stories and actions. This project concludes with a suggestion for just such a new story regarding the human relationship to the natural world, a narrative based on mutuality, interconnectedness, and the searching out of those points where the human and the nonhuman worlds meet and become melted together.
