Comparison of Supervised Classification Models on Textual Data

Text classification is an essential aspect in many applications, such as spam detection and sentiment analysis. With the growing number of textual documents and datasets generated through social media and news articles, an increasing number of machine learning methods are required for accurate textual classification. For this paper, a comprehensive evaluation of the performance of multiple supervised learning models, such as logistic regression (LR), decision trees (DT), support vector machine (SVM), AdaBoost (AB), random forest (RF), multinomial naive Bayes (NB), multilayer perceptrons (MLP), and gradient boosting (GB), was conducted to assess the efficiency and robustness, as well as limitations, of these models on the classification of textual data. SVM, LR, and MLP had better performance in general, with SVM being the best, while DT and AB had much lower accuracies amongst all the tested models. Further exploration on the use of different SVM kernels was performed, demonstrating the advantage of using linear kernels over polynomial, sigmoid, and radial basis function kernels for text classification. The effects of removing stop words on model performance was also investigated; DT performed better with stop words removed, while all other models were relatively unaffected by the presence or absence of stop words.

The Influence of Forest Fire Induced Albedo Differences on the Generation of Mesoscale Circulations

Abstract : The development of a mesoscale circulation by the thermal contrast between a fire burned area surrounded by untouched vegetation was simulated by the Regional Atmospheric Modeling System (RAMS) in order to show the circulation's ability to generate clouds and precipitation. The simulations used two fires that occurred during the summer of 1988. The first fire was over 400 square kilometers in size, while the second fire was over 100 square kilometers in size. Results of the 8-hour simulations showed that the thermal differences between the first fire burn area and surrounding unburned area generated a well- developed mesoscale circulation with a vertical updraft speed of over 3.5 m s-1. The simulation also developed clouds and precipitation directly above the circulation center. Simulation of the second fire burn area generated a mesoscale circulation with a vertical updraft speed of over 2.5 m s-1. Although the second simulation did develop clouds and some very light precipitation, it could not be directly tied to the mesoscale circulation itself.
MTCP : TRANSPORT LAYER SUPPORT FOR HIGHLY AVAILABLE NETWORK SERVICES

OF THE THESIS MTCP : Transport Layer Support for Highly Available Network Services by Kiran Srinivasan Thesis Director: Liviu Iftode We propose a transport layer protocol designed for building highly available Internet network services. The transport layer protocol would provide a mechanism to transparently migrate the server endpoint of a live connection. The connection migration is dynamic and can happen multiple times during a client-service session. Our migration mechanism is client-initiated, integrated in a migration architecture that uniformly addresses various types of events that affect the quality of service perceived by the client. In the architecture, the migration mechanism is independent and decoupled from any migration policies. The migration mechanism can be applied for different contexts like server load balancing, to provide fault tolerance across server crashes, to improve the performance as perceived by the client etc. We examine and address a number of challenges posed by the transfer of connection state required for a connection migration to both the OS and the application layer. We describe the details of our design and an implementation, as well as experimental data that suggests the usefulness of this approach.
Experimental investigation of flapping mechanism of the black-headed gull in forward flight

Many developments in aerospace science have originated from nature. One of these developments has been obtained through inspirations from flying locomotion. The aim of this study is to simulate the flapping mechanism of the black-headed gull in forward flight. The wing of the black-headed gull is characterized entirely by complex dihedral, dividing the wing into two distinct parts. Hence, a flapping mechanism with different bending deflection angles is constructed and compared with a primitive flapping mechanism. Firstly, parametric studies are conducted to assess the role of flapping frequency, velocity and bending deflection angle on the lift, thrust and power loading of the membrane flexible wing at 10 ° angle of attack. Secondly, dimensional analysis is used to establish the similarity between the real gull and the constructed mechanism. Superiority of the bending deflection mechanism is concluded in forward flight against simple flapping wing in terms of aerodynamic forces as well as power loading parameter. It is found that although the aerodynamic coefficients decrease with increase in advance ratio, the best power loading of the black-headed gull is obtained between advance ratio of 2 and 3, in the gull's aerodynamically quasi-steady regime.

Theoretical analysis of key factors achieving reversed magnetic shear q-profiles sustained with lower hybrid waves on EAST

The phase space analysis technique is applied to provide new insights into the fully non-inductive lower hybrid current driven (LHCD) discharges on EAST (Garofalo et al 2017 Nucl. Fusion 57 076037). The analysis shows that there are bounded and unbounded topologies of lower hybrid (LH) waves in phase space. For typical parameters on EAST, the propagation domain for 4.6 GHz LH waves is bounded, while unbounded for 2.45 GHz LH waves and one of the conditions is recognized to be good for achieving an off-axis current profile driven by 4.6 GHz LH waves on EAST. The parametric analysis on the potential power deposition (PPD) region for those experiments demonstrates that the reversed magnetic shear dominates the wave behavior, and confines the LH power absorption to the far off-axis region as long as it occurs in the 4.6 GHz dominated LHCD discharge. GENRAY/CQL3D simulations also confirm this effect of reversed shear on the power absorption of 4.6 GHz waves. A bounded propagation domain and a positive feedback loop between magnetic shear reversal and off-axis LHCD profile could explain the LH-only-sustained strong reversed magnetic shear observed in experiments on multiple machines. In contrast, there is no such effect for 2.45 GHz waves on EAST since the PPD region is less sensitive to the change of reversed shear due to the unbounded propagation domain.
Guidelines for the diagnosis and management of syncope (version 2009).

Guidelines and Expert Consensus Documents summarize and evaluate all currently available evidence on a particular issue with the aim of assisting physicians in selecting the best management strategies for a typical patient, suffering from a given condition, taking into account the impact on outcome, as well as the risk/benefit ratio of particular diagnostic or therapeutic means. Guidelines are no substitutes for textbooks. The legal implications of medical guidelines have been previously discussed. A great number of Guidelines and Expert Consensus Documents have been issued in recent years by the European Society of Cardiology (ESC) as well as by other societies and organizations. Because of the impact on clinical practice, quality criteria for the development of guidelines have been established in order to make all decisions transparent to the user. The recommendations for formulating and issuing ESC Guidelines and Expert Consensus Documents can be found on the ESC Web Site (http://www.escardio.org/guidelines). In brief, experts in the field are selected and undertake a comprehensive review of the published evidence for management and/or prevention of a given condition. A critical evaluation of diagnostic and therapeutic procedures is performed, including assessment of the risk/benefit ratio. Estimates of expected health outcomes for larger societies are included, where data exist.

Energy Budget Observations in the Central Canadian Arctic

To examine the formation process of cold air masses, energy budget observations were carried out in the central Canadian Arctic during mid-winter 1994. A series of cold air mass formations under clear sky, under cloud and during blizzard conditions were observed during this period. Typical energy amounts in these various weather conditions are summarized. The cold air was produced near the surface and accumulated in a strong surface inversion layer as a ridge passed. When a trough approached, the winds became stronger, cold air was mixed upward and transported downstream and may have contributed to anticyclogenesis.
Eurasian Winter Cooling: Intercomparison of Reanalyses and CMIP5 Data Sets

Abstract A cooling trend in wintertime surface air temperature over continental Eurasia has been identified in reanalysis and the Coupled Model Inter-comparison Project phase 5 (CMIP5) ‘historical’ simulations over the period 1989-2009. Here the authors have shown that this cooling trend is related to changes in Arctic sea-ice around the Barents-Kara seas. This study illustrates a consistent spatial and temporal structure of the wintertime temperature variability centered over Asia using state-of-the-art reanalyses and global climate model datasets. Our findings indicate that there is a physical basis for seasonal predictions of near-surface temperatures over continental Asia based on changes to the ice-cover in the Barents-Kara seas.
Nitrogen Fixation in Benthic Microalgal Mats: an important, internal source of "new" nitrogen to benthic communities in Florida Bay

Title of Thesis: NITROGEN FIXATION IN BENTHIC MICROALGAL MATS: AN IMPORTANT, INTERNAL SOURCE OF “NEW” NITROGEN TO BENTHIC COMMUNITIES IN FLORIDA BAY Eric Dale Nagel, Master of Science, 2004 Thesis Directed by: Professor Jeffrey Cornwell Department of Marine, Estuarine and Environmental Science The introduction of “new” nitrogen via nitrogen fixation may have a significant effect on nitrogen availability in estuaries and other partially enclosed aquatic systems. This thesis examines rates of nitrogen fixation associated with benthic microalgal communities in Florida Bay to determine the relative importance of this source as compared to external loads of nitrogen to the system. Nitrogen fixation was measured using a number of experimental techniques to calibrate the use of the acetylene reduction assay and to determine the suitability of the N2:Ar comparison technique for measuring rates of nitrogen fixation. Nitrogen fixation was found to be mediated by benthic microalgae at the surface of the sediments in Florida Bay, and higher rates of fixation were measured in areas dominated by benthic microalgal mats. Nitrogen fixation was highest in the relatively phosphorus-rich western basins and was stimulated by experimental phosphorus additions, suggesting that nitrogen fixation is partially phosphorus-limited.

Discussion Paper Series

This paper investigates the impact of television on internal migration in Indonesia. We exploit the differential introduction of private television throughout the country and the variation in signal reception due to topography to estimate the causal effect of media exposure. Our estimates reveal important long and short run effects. An increase of one standard deviation in the number of private TV channels received in the area of residence reduces future inter-provincial migration by 1.7-2.7 percentage points, and all migration (inter and intra-provincial) by 4-7.4 percentage points. Short run effects are slightly smaller, but still sizeable and statistically significant. We also show that respondents less exposed to private TV are more likely to consider themselves among the poorest groups of the society. As we discuss in a stylized model of migration choice under imperfect information, these findings are consistent with Indonesia citizens over-estimating the net gains from internal migration.

The Effect of Customer Relationship Management on the Satisfaction to Build Customers Loyalty (Study Case of Go-Jek s Transportation Service Users)

This study aims at explaining the effect of the CRM (continuity marketing, one to one marketing, and partnering programs) on customers’ satisfaction and loyalty. This research was conducted on Go-Jek transportation service users in Denpasar city with a total sample of 100 respondents determined based on non probability sampling method namely purposive sampling. The application of CRM is measured by using questionnaires. The analytical tool used in this study is descriptive statistical test and inferential statistical test in the form of path analysis test. The results of the study show that continuity of marketing, one to one marketing, and partnering programs have a positive and significant effect on customers’ satisfaction. One to one marketing is the variable that most influences customers’ satisfaction. Customers’ satisfaction also has a positive and significant influence on customers loyalty, so it can be concluded that forming customer loyalty can be done by improving the customers’ satisfaction.
Colorectal liver metastases: contrast agent diffusion coefficient for quantification of contrast enhancement heterogeneity at MR imaging.

PURPOSE To describe and determine the reproducibility of a simplified model to quantitatively measure heterogeneous intralesion contrast agent diffusion in colorectal liver metastases. MATERIALS AND METHODS This HIPAA-compliant retrospective study received institutional review board approval, and written informed consent was obtained from 14 patients (mean age, 61 years +/- 9 [standard deviation]; range, 41-78 years), including 10 men (mean age, 65 years +/- 8; range, 47-78 years) and four women (mean age, 54 years +/- 9; range, 41-59 years), with colorectal liver metastases. Magnetic resonance (MR) imaging was performed twice (first baseline MR image [B(1)] and second baseline MR image [B(2)]) in a single target lesion prior to therapy. Dynamic contrast material-enhanced MR imaging was performed by using a saturation-recovery fast gradient-echo sequence. A simplified contrast agent diffusion model was proposed, and a contrast agent diffusion coefficient (CDC) was calculated. The reproducibility of the CDC measurement was evaluated by using the Bland-Altman plot and a linear regression model. RESULTS The mean CDC was 0.22 mm(2)/sec (range, 0.01-0.73 mm(2)/sec) on B(1) and 0.24 mm(2)/sec (range, 0.01-0.71 mm(2)/sec) on B(2), with an intraclass correlation coefficient of 0.91 (P < .0001). Bland-Altman plot showed good agreement, with a mean difference in measurement pairs of 0.017 mm(2)/sec +/- 0.096. The slope from the linear regression model was 0.89 (95% confidence interval: 0.63, 1.15) and the intercept was 0.01 (95% confidence interval: -0.08, 0.09). CONCLUSION The CDC enables a quantitative description of contrast enhancement heterogeneity in lesions. Given the high reproducibility of the CDC metric, CDC appears promising for further qualification as an imaging biomarker of change measurement in response assessment.

Influences of the biotic and structural components of Crassostrea virginica on the oyster reef community.

Title: INFLUENCES OF THE BIOTIC AND STRUCTURAL COMPONENTS OF CRASSOSTREA VIRGINICA ON THE OYSTER REEF COMMUNITY. Karen E. Kesler, Doctor of Philosophy, 2015 Directed By: Professor Kennedy T. Paynter, Department of Biology The hard, complex reef structure created by the eastern oyster, Crassostrea virginica, provides refuge and habitat that protects many organisms, allowing them to settle, survive, and spawn. In addition, oysters create copious amounts of biodeposits, which potentially serve as a basal nutrient resource for the reef ecosystem. I investigated the influence of oyster reef structure and oyster biodeposits on the reef community through a series of field experiments and mesocosm studies. Initially, the communities that colonized live oyster reefs were compared to communities that colonized empty oyster shell reefs, to evaluate the potential influence of live oysters that were actively feeding and creating biodeposits. Community assemblages on the two reef types were similar and no differences were seen with species level comparisons of abundance or biomass between the two treatments. The impact of oyster shell structure on energy transfer up the food chain from the basal resource of oyster biodeposits to the predator, Gobiosoma bosc, through the amphipod, Melita nitida was then investigated. Oyster shell structure effectively provided protection to amphipods, with reduction of predation impacts in high complexity habitats when a predator was present. Next, stable isotope signatures (δ13C and δ15N) of dominant reef species and basal resources, including oyster biodeposits, were measured seasonally to evaluate the major resource contributors to the reef. Overall, most carbon sources appeared to be pelagic in nature and an additional unidentified carbon source from outside of the oyster reef was incorporated into the food web. Finally, a δ15N tracer study, utilizing biodeposits labeled with elevated δ15N values, indicated that both Melita nitida and Neanthes succinea could incorporate Crassostrea virginica biodeposits and pass these nutrients to higher trophic levels. These studies suggested that oyster structure played a prominent role in defining the oyster reef community by providing habitat and protection for reef organisms. Mesocosm studies and isotopic analysis indicated that while some deposit feeders could consume oyster biodeposits, biodeposits were likely not a large component of their diet. Overall, these results suggest that structure was the dominant factor driving community organization on the reef, with minimal influence from oyster biodeposits.

Neogene paleomagnetism and geodynamics of the Hikurangi margin, East Coast, New Zealand

Vertical-axis rotations are an important component of Neogene deformation in the New Zealand plate boundary region, and potentially offer fundamental insights into the rheology of continental crust. Extensive paleomagnetic sampling along the Hikurangi margin, on the East Coast of the North Island, has provided new insights into the patterns, rates and timings of tectonic rotation, and also an improved understanding of the magnetic signature of New Zealand Cenozoic mudstones. Rigorous field tests reveal numerous late remagnetizations, which haveoften formed several million years after deposition and can be irregularly distributed within an outcrop. Scanning electron microscopy and rock magnetic analyses indicate that the remanence carrier is predominantly the ferrimagnetic iron sulphide, greigite, which is present as a mixed population of single domain and superparamagnetic grains that are characteristic of arrested authigenic growth. Strong viscous overprints are the result of later, usually recent, oxidation of these sulphides. The recognition of late-forming magnetizations leads to a completely new view of the Neogene tectonic evolution of the Hikurangi margin, with no tectonic rotations being evident prior to 8–10 Ma; coherent rotation of most of the Hikurangi margin since that time refutes the existence of the independently rotating ‘domains’ that were inferred from earlier paleomagnetic data. This pattern is more consistent with the short-term velocity field, and allows all Neogene rotation to be more simply explained as a large-scale response to realignment of the subducting Pacific plate. Tectonic rotations have been accommodated by a variety of structures since 10 Ma; in the Late Miocene and Pliocene, rates of tectonic rotation were 3–4 times faster than presently observed and possibly involved a much larger region, before initiation of the North Island Dextral Fault Belt and the Taupo Volcanic Zone at 1-2 Ma instigated the current tectonic regime. Collision of the Hikurangi Plateau in the Late Miocene is interpreted to have caused both the initiation of tectonic rotation, and the widespread remagnetization of sediments, making it a key event in the Neogene evolution of the plate boundary region.
