Fluidization of biomass particles is an important process in the gasification, pyrolysis and combustion in order to extract energy from biomass. Studies on the fluidization of biomass particles (corn cob and walnut shell), inert particles (sand, glass bead, and alumina), which are added to facilitate fluidization of biomass, and biomass/sand mixture were performed. Experiments were carried out in a 14.5 cm internal diameter cold flow fluidization bed to determine minimum fluidization velocities with air as fluidizing medium. On the of basis of experimental data from both present work and those found in the literature, new correlations were developed to predict minimum fluidization velocity for inert particles as well as biomass particles. It was found that the proposed correlations satisfactorily predict minimum fluidization velocities and was in well agreement with experimental data. Furthermore, effect of weight percentage of biomass in the biomass/sand mixtures was studied. The weight fraction of biomass particles in the mixture was chosen in the range of 0 ~ 100 wt. %. The results show that minimum fluidization velocity of the mixtures increases with an increase in biomass content. Using the present experimental data, a new correlation was developed in terms of mass ratio for predicting values of …

Alkali-silica reaction (ASR) in cement is a major contributor to failure of cement structures around the world, causing increased repair costs and possible rebuild expenses. Alkali levels are indicative of the potential for ASR and are therefore measured and quantified. A linear correlation relating cement alkali concentration measured by X-ray fluorescence spectroscopy (XRF) and peak ratio measured by Fourier transform infrared spectroscopy (FTIR) is developed. Regression analysis of plots correlating alkali content measured by FTIR absorption band (750 cm-1/923 cm-1) ratio versus equivalent alkali (Na2O)e (%Na2O + 0.658 % K2O) quantified by XRF show linear correlation coefficient, R2, of 0.97. Results of this investigation are discussed in terms of microstructural disorder coefficient Cd which is a reactivity criterion for ASR-susceptible aggregates proposed by Bachiorrini [31]. XRF is a popular technique for alkali quantification but FTIR is faster, safer, and less expensive technique compared to XRF. Portable instrumentation is available for both techniques but FTIR systems are less expensive.

This research discusses how the design of a tornado forward error correcting channel code (FEC) sends digital data stream profiles to the receiver. The complete design was based on the Tornado channel code, binary phase shift keying (BPSK) modulation on a Gaussian channel (AWGN). The communication link was simulated by using Matlab, which shows the theoretical systems efficiency. Then the data stream was input as data to be simulated communication systems using Matlab. The purpose of this paper is to introduce the audience to a simulation technique that has been successfully used to determine how well a FEC expected to work when transferring digital data streams. The goal is to use this data to show how FEC optimizes a digital data stream to gain a better digital communications systems. The results conclude by making comparisons of different possible styles for the Tornado FEC code.

The aim of the current study was to examine how thinking about qualitatively different social network members may differentially affect cardiovascular reactivity to a subsequent stressor. Eighty-two undergraduates were asked to think and write about different types of relationships preceding a social stressor. No differences between conditions in CVR were found during social support induction phase or the stressor task. Women in the supportive condition were found to have slower SV recovery than those in the ambivalent condition. The results of this study are inconsistent with previous evidence for a relationship between mental representations of social ties and CVR. Future research should seek to rule out confounding variables and clarify this effect.

In today’s fast paced world, as the number of stations of television programming offered is increasing rapidly, time accessible to watch them remains same or decreasing. Sports videos are typically lengthy and they appeal to a massive crowd. Though sports video is lengthy, most of the viewer’s desire to watch specific segments of the video which are fascinating, like a home-run in a baseball or goal in soccer i.e., users prefer to watch highlights to save time. When associated to the entire span of the video, these segments form only a minor share. Hence these videos need to be summarized for effective presentation and data management. This thesis explores the ability to extract highlights automatically using MPEG-7 features and hidden Markov model (HMM), so that viewing time can be reduced. Video is first segmented into scene shots, in which the detection of the shot is the fundamental task. After the video is segmented into shots, extraction of key frames allows a suitable representation of the whole shot. Feature extraction is crucial processing step in the classification, video indexing and retrieval system. Frame features such as color, motion, texture, edges are extracted from the key frames. A baseball highlight contains certain …

This collection consists of a critical preface and nine essays. The preface analyzes, first, how the imagination influences the personal journey of a writer, and second, the techniques authors use, mainly form, time, and space, to enact the imagination and propel the reader into an imagined narrative. The essays explore themes of loss, mental illness, the rift between the “real” and the “imagined” life, and the intangibility of memory itself. Collection includes the essays “Into the Snow,” “No Longer a Part,” “Borderland,” “Still Wounds,” “What Stays in Las Vegas,” “Remnants,” “The Root,” “Your Father,” and “The Land Lord.”

The oratorio August 4, 1964 is a twelve-movement work for orchestra, chorus, and four soloists written by Steven Stucky. The premise for the libretto, adapted by Gene Scheer, is the confluence of two events during one day (August 4, 1964) in the life of Lyndon B. Johnson. Although the main idea of the libretto focuses on these two events of this one day, many cultural references of the 1960's in general can be found as well, such as quotations from the well-known song "We Shall Overcome." Stucky borrows from a motet he wrote in 2005 for another quotation source utilized in this oratorio, "O Vos Omnes." My goal in this thesis is to reveal and analyze the many different levels of quotations that exist within August 4, 1964, to explore each quotation's individual function within the oratorio (as a cultural gesture, commentary or remembrance), and to examine the structural coherence that emerges as a result of their use within the oratorio.

This exploratory case study aims to develop a set of best practices for integrating online discussion forums into the foreign language curriculum, focusing specifically on a group of learners in an advanced French grammar course at a large, public U.S. university. During a period of two months, 26 participants completed a series of tasks designed to provide three different types of data: 1) exploration and analysis of interactional, linguistic, and social features of Web forum discourse; 2) participation in Web forums; and 3) feedback from students. Since the feedback received from two questionnaires was ultimately the most consistent and reliable type of data collected, this study focuses on students' participation patterns and their perceptions of Web forums as a communication space having the potential to provide opportunities for learning French. Although some students indicated that they would neither consider visiting a French-language Web forum nor actually visit one, in both cases, more than half of the participants who completed these questionnaires indicated that they would both consider visiting a French-language Web forum and might actually visit one. Since encouraging students to use French beyond the classroom and to engage in the lifelong use of French for personal enrichment (following the …

The most effective and useful way to diagnose and subtype depression has been a long debated topic which even now does not have a definite answer. The biopsychosocial approach to diagnosis may be a solution to this problem by linking various etiologies to symptom presentation. The biopsychosocial model, in regard to depression, takes into account biological risk factors/contributors, psychological or cognitive risk factors/contributors, and social risk factors/contributors to depression when making diagnosis and subtyping determinations. However, the most effective way to use this model in the assessment, diagnosis, and treatment of depression is not yet clear. In this study, the utility of the biopsychosocial model as an effective approach to conceptualizing and treating depression was assessed by testing hypotheses that showed that etiological contributors are related to the presence and differential presentation of depression, and that these etiologically-based subtypes of depression respond differently to different forms of treatment. These hypotheses were tested using data from the National Comorbidity Survey - Replication (NCS-R). Results showed that the biopsychosocial model can effectively predict the presence, severity and chronicity of depression, and may inform specific biopsychosocially-based subtypes. No conclusions could be drawn regarding success in treatment based on the biopsychosocial model. Future directions …

This study examines the extent to which locus of control and social support are linked to self-efficacy with regard to disease management in HIV-positive adults. Perceived ability to effectively manage illness was measured with the Self-Efficacy for Managing Chronic Disease Scale. Scores from the Multidimensional Scale of Perceived Social Support and the Multidimensional Locus of Control Scale were used as predictors. The gender-balanced sample (N = 69) of HIV+ adults was primarily African-American (65.3%) and European American (30.5%), with a mean age of 47 years (SD = 8.37). Correlational analyses suggested significant positive relationships between self-efficacy, social support, and locus of control due to powerful others. A regression analysis found that the model accounted for 23% of the variance in self-efficacy (adj. R-squared =.23, F (5, 63) = 4.81, p < .01), with social support (&#946; = .37, t = 3.28, p < .01) and locus of control (&#946; = .25, t = 2.26, p < .05) both significant predictors. Results suggest that social support and locus of control contribute to the belief that HIV can be managed. Interestingly, an external locus of control contributed to this belief, perhaps due to the perception of a physician, religious icon, or partner …

Video surveillance systems have been commonly used in transportation systems to support traffic monitoring, speed estimation, and incident detection. However, there are several challenges in developing and deploying such systems, including high development and maintenance costs, bandwidth bottleneck for long range link, and lack of advanced analytics. In this thesis, I leverage current wireless, video camera, and analytics technologies, and present a wireless traffic monitoring system. I first present an overview of the system. Then I describe the site investigation and several test links with different hardware/software configurations to demonstrate the effectiveness of the system. The system development process was documented to provide guidelines for future development. Furthermore, I propose a novel speed-estimation analytics algorithm that takes into consideration roads with slope angles. I prove the correctness of the algorithm theoretically, and validate the effectiveness of the algorithm experimentally. The experimental results on both synthetic and real dataset show that the algorithm is more accurate than the baseline algorithm 80% of the time. On average the accuracy improvement of speed estimation is over 3.7% even for very small slope angles.

This essay describes a pattern oriented data structure, or PODS, as a system for storing computer music data. It organizes input by sequences or patterns that recur, while extensively interlinking the data. The interlinking process emulates cognitive models, while the pattern processing draws specifically from music cognition. The project aims at creating open source external objects for the Max/MSP software environment. The computer code for this project is in the C and Objective-C computer programming languages.

Tissue engineering merges the disciplines of study like cell biology, materials science, engineering and surgery to enable growth of new living tissues on scaffolding constructed from implanted polymeric materials. One of the most important aspects of tissue engineering related to material science is design of the polymer scaffolds. The polymer scaffolds needs to have some specific mechanical strength over certain period of time. In this work bioresorbable aliphatic polymers (PCL and PLLA) were blended using extrusion and solution methods. These blends were then extruded and electrospun into fibers. The fibers were then subjected to FDA standard in vitro immersion degradation tests where its mechanical strength, water absorption, weight loss were observed during the eight weeks. The results indicate that the mechanical strength and rate of degradation can be tailored by changing the ratio of PCL and PLLA in the blend. Processing influences these parameters, with the loss of mechanical strength and rate of degradation being higher in electrospun fibers compared to those extruded. A second effort in this thesis addressed the potential separation of the scaffold from the tissue (loss of apposition) due to the differences in their low strain responses. This hypothesis that using knit with low tension will …

This collection contains a preface entitled "Of Other Worlds" and the following short stories: "The Mind's Eye," "Waking," "The Conquest of the World," "Persephone," and "Extradition." This creative thesis includes a blend of science fiction and literary realism short stories, which are collectively concerned with questions of time, narration, and the use of language. As well, the preface discusses science fiction theory, narrative strategies such as the use of the first person perspective, and the author's theory of composition.

This paper examines the use of infinitival and gerundial constructions by intermediate Spanish learners. The use of those two patterns creates problems for second language learners at intermediate and advanced levels. However, there are only few studies on their second language acquisition, and fewer focus on Spanish learners. This study tries to resolve this and to this end, I retrieved all hits of the two constructions from the Spanish component of the International Learner Corpus of English (SP-ICLE). I run a distinctive collexeme analysis (DCA) to identify the verbs that are associated with either pattern. The results are discussed at three different levels: (i) the identification of verbs that Spanish learners associate with each construction; (ii) a systematic comparison with previous studies on native speakers to show possible similarities/discrepancies; and (iii) a comparison of the results with findings on German learners to discuss possible effects of language similarity and transfer.

Caregivers for individuals diagnosed with Alzheimer's disease (AD) shoulder a remarkably complex burden as compared to other caregivers of elderly individuals. For long distance caregivers, geographical separation further compounds the problems experienced by AD caregivers, as they are isolated from family members and support networks. Both on-site and long-distance AD caregivers experience uncertainty; the findings from this study illustrate how AD caregivers manage the uncertainty of the disease and primary care, as well as how uncertainty differs between on-site and long-distance caregivers. AD caregiver (N = 13) interviews were transcribed and qualitatively analyzed using uncertainty management theory as a thematic lens. The analysis revealed that AD caregivers experience overwhelming feelings of burden, guilt, and doubt; however, these feelings manifest differently depending on caregiver type. The findings of this study demonstrate that sources for obtaining information regarding AD and caregiving were useful for on-site caregivers; however, the sources did not account for the needs of long-distance caregivers or the psychosocial needs of on-site caregivers. Furthermore, AD caregivers did not seek support or information about AD and caregiving from health care professionals. Implications for future research regarding long-distance and on-site AD caregiving are discussed.

Directly mapped caches are an attractive option for processor designers as they combine fast lookup times with reduced complexity and area. However, directly-mapped caches are prone to higher miss-rates as there are no candidates for replacement on a cache miss, hence data residing in a cache set would have to be evicted to the next level cache. Another issue that inhibits cache performance is the non-uniformity of accesses exhibited by most applications: some sets are under-utilized while others receive the majority of accesses. This implies that increasing the size of caches may not lead to proportionally improved cache hit rates. Several solutions that address cache non-uniformity have been proposed in the literature. These techniques have been proposed over the past decade and each proposal independently claims the benefit of reduced conflict misses. However, because the published results use different benchmarks and different experimental setups, (there is no established frame of reference for comparing these results) it is not easy to compare them. In this work we report a side-by-side comparison of these techniques. Finally, we propose and Adaptive-Partitioned cache for multi-threaded applications. This design limits inter-thread thrashing while dynamically reducing traffic to heavily accessed sets.

Retail geography is an expanding field that is becoming increasingly important within academia, the business environment, and the national and global economy. The focus of this study is to provide insight and additional understanding of the site selection processes employed by Wal-Mart in the United States. The research studies Wal-Mart from a national perspective and investigates the patterns of retail store expansion across the United States from 1990 to 2005. The study employs the use of a continuous Poisson model to check for significant clustering, and a single and multiple correlation analysis to identify the types of relationships that exist between retail stores and location. The results of the study make apparent several distinct patterns of retail store dispersion within the United States between the years 1990 to 2005.

Mahler's Ninth Symphony, since its premier in 1912, has sparked much debate about its programmatic meaning. This thesis provides an in-depth analysis of the Adagio and an examination of the controversy of the farewell story. In the process of the analysis I have compared my findings to some of the important authors in Mahler's field such as Vera Micznik, Henry-Louis de La Grange, and Christopher Orlo Lewis. Some of the conclusions are that a closer investigation of the music is necessary and that the programmatic reading of the farewell story can be appropriate.

In this study, pro-environmental behaviors are investigated by studying if one's primary information sources about environmental issues either from their social network or the media influence this behavior. Data was collected from the 2002 Detroit Area Study with a total of 267 respondents. Three indexes were constructed to separately measure all seven pro-environment behavioral items, five conservation behavioral items, and two consumption behavioral items. A complex sample model was utilized in these analyses. Findings suggest that information sources are correlated to self-reported environmental behavior. As predicted, the people whose primary information source was social network were more likely to obtain higher scores on all three separate indexes than those individuals who primarily received information about environmental issues from the media.

Occupation operations are some of the most resource and planning intensive military undertakings in modern combat. The United States Army has a long tradition of conducting military government operations, stretching back to the Revolutionary War. Yet the emergence of military government operational doctrine was a relatively new development for the United States Army. During the World Wars, the Army reluctantly embraced civil administration responsibilities as a pragmatic reaction to the realities of total war. In the face of opposition from the Roosevelt administration, the United States Army established an enduring doctrine for military government in the crucible of the European Theater of Operations.

The American military experience in the European Theater of Operations during the Second World War is one of the most heavily documented topics in modern historiography. However, within this plethora of scholarship, very little has been written on the contributions of the United States Cavalry to this era. The six mechanized cavalry groups assigned to the Third Army served in a variety of roles, conducting screens, counter-reconnaissance, as well as a number of other associated security missions for their parent corps and the Army. Although unheralded, these groups made substantial and war-altering impacts for the Third Army.

Although widely viewed in the West, Japanese films are often misunderstood, as they are built on cultural, theatrical, and aesthetic traditions entirely foreign to Western audiences. Particularly in regards to Japan's "fantastic" cinema - including giant monster pictures, ghost stories, and "J-Horror" films - what is often perceived as "cheap" or "cheesy" is merely an expression of these unique cultural roots. By observing and exploring such cultural artifacts as kabuki, noh, and bunraku - the traditional theatrical forms of Japan - long-standing literary traditions, deeply embedded philosophical beliefs, and even more recent developments such as the controversial dance form butoh, these films, including Gojira (1954), Daimajin (1966), Kwaidan (1964), Onibaba (1964), Testuo the Iron Man (1989), and Ju-On (2002), can be placed in their proper perspective, leading to a reevaluation of their worth not merely as commercial products, but as uniquely Japanese expressions of that society's unique place in world culture.
