Abstract:
This exploratory study focuses on the relationship between vocal expression, musical structure, and emotion in recorded performances by famous singers of three Schubert songs. Measurement of variations in tempo, dynamics, and pitch showed highly systematic relationships with the music's structural and emotional characteristics, particularly as regards emotional activity and valence. Relationships with emotional activity were consistent across both singers and musical pieces, while relationships with emotional valence were piece-specific. Clear changes in performing style over the twentieth century were observed, including diminishing rubato, an increase followed by a decrease of the use of pitch glides, and a widening and slowing of vibrato. These systematic changes over time concern only the style of performance, not the strategies deployed to express the structural and emotional aspects of the music.

Abstract:
Background: In developing the PB-50 word lists, J. P. Egan suggested five developmental principles, two of which were “equal average difficulty” and an “equal range of difficulty” among the lists (page 963). Egan was satisfied that each of the 20 PB-50 lists had equivalent ranges of recognition performances and that the lists produced the same average performances. This was accomplished in preliminary studies that measured the recognition performance of each word and eliminated words that were always or never correct. In preparing for studies of interrupted words, we needed to know the range of difficulty inherent in the speaker specific NU-6 and Maryland CNC materials we planned to use when those words were not interrupted. There were only a few studies in the literature that touched on the range of difficulty characteristic of the word-recognition materials in common usage. The paucity of this information prompted this investigation whose scope broadened to include the CID W-22, Maryland CNC, NU-6, and PB-50 materials spoken by a variety of speakers. Purpose: The purpose was to evaluate the homogeneity with respect to intelligibility of the words that comprise several of the common word-recognition materials used in audiologic evaluations. Research Design: Both retrospective (10) and prospective (3) studies were involved. Data from six of the retrospective studies were from our labs. The prospective studies involved both listeners with normal hearing for pure tones and listeners with sensorineural hearing loss. Study Sample: The sample sizes for the 13 data sets ranged from 24 to 1,030, with 24 the typical number for listeners with normal hearing. Data Collection and Analysis: The retrospective data were from published studies and archived data from our laboratories. The prospective studies involved presentation of the word-recognition materials to the listeners at a comfortable level. An item analysis was conducted on each data set with descriptive statistics used to characterize the data. Additionally, skewness coefficients were calculated on the distributions of word performances and the interquartile range was used to determine minor and major outliers within each set of 200 words and their component 50-word lists (300 words for the Maryland CNCs). Results: For listeners with normal hearing the majority of performances on the words within a 50-word list were better than the mean performance, which produced negatively skewed distributions with outlier performances in every list. For listeners with sensorineural hearing loss the performances on the words within a 50-word list were evenly distributed above and below the mean performance, which yielded essentially normal distributions with few outliers. There were a few words on which performances were better by the listeners with hearing loss. Conclusions: Every list of word-recognition materials has a few words on which recognition performances are noticeably poorer than performances on the majority of the remaining words. If the intention of an experiment is to evaluate performance at the word level, then identifying these “outliers” becomes a necessity. Although not evaluated in this report, the implications for 25-word lists are they should be based on recognition-performance data and not compiled arbitrarily.

Abstract:
Studies of duration in music performance since the 1980s have focused on the role of duration in the communication of musical structure, namely grouping and metric structure. This article posits a broader view of duration in performance, namely that performers choose durations to facilitate or inhibit listener-performer synchronicity. Listeners who maintain synchronicity are continually rewarded for making accurate predictions of when events will happen, and thus the loss of synchronicity might hazard feelings of frustration or isolation. Performers, by choosing durations that are difficult to predict, can therefore enlist these feelings in dynamic narratives of synchronicity that augment trajectories in the score. The article explores two such narratives, found in seventeen participants’ attempts to synchronize to two idiosyncratic renditions of passages of Chopin’s mazurkas. By ascribing significance not only to the choices of performers and composers but also to how individual listeners attend to those choices, the article aims to widen the circle of agencies ascribed with the ability to affect the meaning of musical works.

Abstract:
This study examined the intrarater and interrater reliability of the Test of Gross Motor Development—3rd Edition (TGMD-3). Participants were 60 Finnish children aged between 3 and 9 years, divided into three separate samples of 20. Two samples of 20 were used to examine the intrarater reliability of two different assessors, and the third sample of 20 was used to establish interrater reliability. Children’s TGMD-3 performances were video-recorded and later assessed using an intraclass correlation coefficient, a kappa statistic, and a percent agreement calculation. The intrarater reliability of the locomotor subtest, ball skills subtest, and gross motor total score ranged from 0.69 to 0.77, and percent agreement ranged from 87 to 91%. The interrater reliability of the locomotor subtest, ball skills subtest, and gross motor total score ranged from 0.56 to 0.64. Percent agreement of 83% was observed for locomotor skills, ball skills, and total skills, respectively. Hop, horizontal jump, and two-hand strike assessments showed the most difference between the assessors. These results show acceptable reliability for the TGMD-3 to analyze children’s gross motor skills.

Abstract:
All too often, critics, historians, and music analysts draw upon the aesthetic and analytic language of composition to describe and account for performed interpretations. This article explores the inequities and challenges that derive from this borrowing of language. Yet a study of Ernst Levy and his recorded performance of Brahms, however, reveals how compositional aesthetics can also be appropriated and repurposed to new creative ends.

Abstract:
The study investigates the aesthetic experience of a dance performance from the perspective of both the dancers and the audience. The audience observed three short custom-made choreographies that were presented live and then watched the recorded versions, and judged them on an instrument designed to measure the aesthetic experience of dance. The choreographies were performed by six dancers. The dancers judged their own performances as well as the recorded versions of the performances. The analyses revealed that the dancers? aesthetic experience of a dance performance is similar when they perform choreography and watch it on video. On the other hand, the audience showed a higher sensitivity to live performance: they judged the live performance higher on all dimensions of aesthetic experience compared to their video presentation.

Abstract:
We measured the postural sway of two trombonists as they each recorded multiple performances of two solo pieces in each of three different expressive styles (normal, expressive, non-expressive). We then measured the postural sway of 29 non-trombonist listeners as they moved their arms and body, “air-conducting” the recorded sound as if to draw out the emotion from the performance (Experiment 1), and of the two trombonists as they played along with the same recorded performances (Experiment 2). In both experiments, the velocity of listeners’ postural sway was more like that of the performer than expected by chance. Listeners entrained more to back-and-forth than to side-to-side sway in Experiment 1 and only to back-and-forth sway in Experiment 2. Entrainment was not due entirely to performer and listener both swaying to the musical pulse in the same way. Listeners in Experiment 1 rated performances as more expressive when they entrained more, suggesting that entrainment enhanced their aesthetic experience of the music. The whole body appears to contribute to unpacking the expressive content of musical communication.

Full text
Abstract:
This dissertation presents evidence for the influence which tenor Enrico Caruso had on the Italian Vocal Tradition. This impact was clearly boosted by the revolution realized in the fledgling recording industry, and the recordable disc. In the years of 1902-1920 gramophones became commonplace, and collecting recordings became an interest for many. This new technology required specialized skills, and was especially suited to certain qualities of voice. Caruso enjoyed immense success in this medium, in recording over 250 records. Italian vocal style at the turn of the century was changing, and Caruso employed a new "modern" style in his singing. His interpretive decisions, vocal method, and repertoire which he championed had an impact on the vocal tradition of future generations. Comparison of his recordings with tenors Fernando de Lucia, Giuseppe Anselmi, and Alessandro Bonci shows a marked contrast in styles of "the old school" and Caruso's "more straightforward" approach. A collection of historical documents for those who succeeded him include many biographies, reviews, and quotes to demonstrate the extent of his influence. Recordings also show a movement toward "the Caruso Sound." Jussi Bjoerling, Franco Corelli, Richard Tucker, Mario Lanza, and Luciano Pavarotti were all influenced by the great Caruso. Almost 100 years have passed since he sang his last performance. He continues to inspire singers to this day, through his recordings and legacy passed on by many generations. He is the ideal, the measuring stick for all tenors to follow, and continues even to today.

Abstract:
The inter-war period of the twentieth century represents something of a ‘golden age’ in solo violin playing. In addition to an unprecedented degree of technical prowess, a huge amount of variety existed between different performers, with the majority of well-known artists exhibiting their own unique sound and manner of delivery. One area of expression in which a divergence of approach is most evident is that of musical timing, whereby performers utilise what is generally termed ‘rubato’ in order to convey either the structure or emotional character of the music. This thesis utilises specialised computational methods of empirical analysis in order to investigate how rubato is used in thirty recordings of the Adagio from Brahms’ Violin Concerto, Op. 77, made by eminent performers who were active during this period. By comparing these recordings in detail, the principle aim is to ascertain just how much performers differ in their approaches to musical timing and, conversely, where there is some degree of common practice. Literary sources pertaining to rubato from the late-nineteenth and early-twentieth centuries are also scrutinised, in order to determine to what extent these written descriptions of rubato relate to use of the device in real-life performances. Key stylistic traits are identified and categorised, in order to inform performers who are looking to incorporate something of this twentieth-century style of rubato into their own playing. To date, the vast majority of empirical studies of performance have been conducted in the field of music psychology, with musicological approaches tending to favour closelistening methods in order to identify key stylistic traits. This study has attempted to use both empirical analysis and close-listening in tandem, which allows for the identification of common timing patterns across all thirty recordings, as well as the detailed examination of idiosyncrasies within their respective musical contexts. Sonic Visualiser software has been used to create a number of innovative video examples that incorporate tempo graphs with the original recorded sound, in order to see and hear what is happening in the music simultaneously.

Abstract:
This article takes a participatory approach to the reproduction of live music performance by looking at the history of »bootleg« sound recordings in two formations during the 1960s and 1970s. The first builds on the history of how opera lovers, mostly in concert and sometimes in conflict with formal opera institutions and commercial recording companies, created their own community for reproduced live opera performances through surreptitious live recording, record producing, distributing, cataloging, trading, and collecting. Marsha Siefert relates these activities to the world of magnitizdat, the live music recordings in the U.S.S.R. that were also reproduced and circulated through trusted networks. The aim of looking at both of these twentieth-century forms of music reproduction is to ask questions about how music listeners responded to perceived limitations of formal music industries by creating participatory networks that identified, reproduced, and circulated recorded music that corresponded to their preferences and ideas about authenticity, aesthetics, and direct experience before the internet age.

Abstract:
AbstractThe emotions that students experience when engaging in tasks critically influence their performance and many models of learning and competence include assumptions about affective variables and respective emotions. However, while researchers agree about the importance of emotions for learning, it remains challenging to connect momentary affect, i.e., emotions, to learning processes. Advances in automated speech recognition and natural language processing (NLP) allow real time detection of emotions in recorded language. We use NLP and machine learning techniques to automatically extract information about students’ motivational states while engaging in the construction of explanations and investigate how this information can help more accurately predict students’ learning over the course of a 10-week energy unit. Our results show how NLP and ML techniques allow the use of different modalities of the same data in order to better understand individual differences in students’ performances. However, in realistic settings, this task remains far from trivial and requires extensive preprocessing of the data and the results need to be interpreted with care and caution. Thus, future research is needed before these methods can be deployed at scale.

Abstract:
The present study is motivated by several observations of unexpected, recurring, high levels of power for stall-regulated wind turbines operating under very low temperatures. As power levels recorded largely exceed design levels of the rotor, operation in such conditions can cause dramatic damage to turbine. This study aims to understand the origin of such phenomenon by analyzing experimental data gathered from a stall-controlled wind turbine, having a nominal power of more than 500 kW, and comparing the experimental behaviour with numerical simulations. To provide a quantitative estimate of density and atmospheric turbulence effects on power output, a procedure based on the IEC 61400-12 international standard for elaboration of a wind turbine power curve is used. The numerical simulations is based on the solution of the time-averaged, steady-state, incompressible Navier-Stokes equations with an appropriate turbulence closure model. The actuator disk model, together with blade element theory, are used to model the turbines. The stall-regulated turbine analyzed has shown to produce measured power increases significantly higher than increases of density. Regarding the influence of turbulence intensity, it has been observed that for constant hub height incoming wind velocity and density, power output increases with turbulence intensity at low winds, the opposite being true at higher winds. The numerical simulations show a good agrement with the measurements.

Abstract:
A deepwater Spar Drilling Production Storage Offloading (SDPSO) floating system or Spar FPSO that integrates Spar dry-tree production, oil storage and offloading has been proposed for offshore oil exploitation. Benefits of the deep drafted first generation classic Spar, such as excellent stability and hydrodynamic performances that allow dry tree drilling and production, large capacity of the mid hull section for oil storage, cost efficiency for construction and save in-service operations, are combined to provide a competitive solution from moderate deep water of 300m to ultra-deep water of 3,000m. The present Spar FPSO is proposed for the potential deepwater oil field development in South China Sea. It uses the hull mid-section with large capacity for wet oil storage, utilizing the density difference between the oil and the sea water for wet storage and oil-water displacement in the storage tank. To demonstrate the feasibility and to investigate its hydrodynamic performances of the Spar FPSO, comprehensive experimental investigations, including the in-place model tests in the deepwater offshore basin and the VIM model tests in the towing tank, have been undertaken. For the in-place model tests, both the stand alone and the tandem offloading conditions were considered. The classic Spar hull, the taut mooring system and the top tensioned risers (TTRs) were all included to represent the coupling effects of the whole system. Various metocean environments, such as the 100-year storm, the 1-year storm and the offloading condition, were considered to give a complete assessment. Different mooring configurations were also studied to adapt to the deep and moderate water depths correspondingly. The global responses, such as the hull six degree of freedom motions, top tensions of mooring lines and risers, possible green water occurrences, were monitored and recorded in real time. Additionally, a preliminary VIM experiment was also carried out in the towing tank since the vortex induced motions (VIM) is one of the most concerned issues for the deep drafted Spar. The VIM characteristics with different heading angles and current velocities were obtained. It is demonstrated that the Spar FPSO has satisfactory hydrodynamic and VIM performances in metocean environmental conditions in South China Sea.

Abstract:
The development of devices capable of delivering tactile and thermal feedback have the potential to improve brain-machine interfaces for neurorehabilitation protocols. Monetary rewards are known to improve some types of passive tactile processing. The aim of this study was to describe the performance and neural activity of subjects receiving tactile stimuli through a tactile stimulation sleeve in the presence or absence of monetary rewards. Healthy subjects were required to discriminate between different tactile stimulation patterns delivered through a stimulation sleeve while their neural activity was recorded with Electroencephalography (EEG). Behaviorally, no significant differences were observed in the performances of subjects wearing the sleeve. Meanwhile, analysis of neural activity revealed that the introduction of monetary rewards consistently generated significant differences in theta frequency band for occipital electrodes. These results support the notion that monetary rewards can significantly influence tactile information processing.

Abstract:
Abstract Land-based power units have to fulfill even more high levels of production and reliability. In harsh environments (desert and tropical installations, typically), the power unit ingests high amounts of dust that might deposit inside the compressor. In this paper, the analysis of a multistage compressor performance that operates under sandy and humid conditions has been assessed. The compressor units, that equips the Allison 250 C18 compressor, has been subjected to multiple runs under severe conditions of soil dust ingestion. The compressor has been operated according to subsequent runs and at the end of each run, the performance curve was recorded and the performance losses, in terms of pressure ratio, have been measured during the operations. The characteristic curve of each run is representative of the level of contamination of the unit. Finally, the compressor has been washed and the performance curve, in the recovered conditions, has been recorded. The results show the modification and the downward shift of the characteristic curves which lead to a gradual loss of the compressor performance. The curves realized after dust ingestion have been compared with the recovered curve after online washing. The measurement shows a promising recovery of the performances, even if, the compressor flow path appears affected by localized deposits able to resist to the droplet removal action. Detailed photographic reports of the IGV and the first compressor stages have been included in this analysis. After each run, the IGV, the rotor blade and stator vane of the first stage and the hub and the shroud surfaces have been photographed. The pictures show the deposition patterns on the blades and the compressor surfaces. The comparison of the pictures of the internal surfaces, before and after the washing, highlights the parts that are more critical to clean and needy of attention during offline washing and overhaul.

Abstract:
Abstract Sea state conditions can be estimated from the motion of a moving ship by converting its response to incident waves through the response amplitude operator. The method is applied herein to ship motion data from the icebreaker R/V Akademik Tryoshnikov and recorded during the Antarctic Circumnavigation Expedition across the Southern Ocean during the Austral summer 2016–17. The response amplitude operator of the vessel was estimated using two boundary element method models, namely NEMOH and HydroSTAR. An inter-comparison of model performance is discussed. The accuracy of the reconstructed sea states is assessed against concurrent measurements of the wave energy spectrum, which were acquired during the expedition with the marine radar WaMoS-II. Results show good agreement between reconstructed sea states (wave spectrum as well as integrated parameters) and direct observations. Model performances are consistent. Nevertheless, NEMOH produces slightly more accurate wave parameters when quantitatively compared against HydroSTAR.

Abstract:
Abstract Suspension plasma spraying is gaining greater interest for emerging applications such as new thermal barrier coatings, next generation environmental barrier coatings and ceramic membranes as in solid oxide fuel cells. Mettech developed an axial injection plasma process coupled with an automatic suspension feed system, and demonstrated its capability to overcome the complexities of the process and deliver quality coatings. This paper aims at determining the durability and stability of the gun, suspension feeder and their components. A 120-hour duration test was performed, and the plasma torch and suspension feed parameters and performances were recorded. The test results indicate that the equipment and process are stable and reliable, and ready for industrial applications.

Abstract:
Recent works related to digital self-instruction environments, present scarce efforts to provide combined instruction for gestural and vocal skills. Based upon a recently introduced learning and teaching method of vocal music, this research utilizes existing technologies to achieve the development of such a learning environment. The presented system administers the learning experience in order to improve the motion, sound and rhythm related skills of the student. Student performance is compared with a pre-recorded instructor performance in order to provide customized feedback that bespeaks the flaws of the former performance. Motion and sound-capturing technologies are combined, and related feature extraction algorithms are applied. The gestural and vocal features of the instructor performance are compared off-line to those of the student performance, in order to detect the differences, while the tempo is indicated through gestures. The system evaluates constantly the performances in order to provide visual feedback based on their differences. The aim is for the student to reproduce the instructor performance in an approximate manner. An assessment formula for the student performance is proposed and tested for its validity and accuracy. The selected musical genre on which this system was applied is Byzantine music, since its complexity and variety tests the existing sound recognition algorithms.

Abstract:
Two-phase (phase-change) microchannel (MC) system is a promising technology for achieving enhanced heat removal for highdensity electronics. Yet phase-change studies in MCs with hydraulic diameters on the order of several hundred micrometers or smaller have been inconclusive. Most of earlier studies involved one specific channel design and one type of working fluid. It is thus difficult to make fair comparisons across various experimental works toward recommending the best design option for real applications under specific operating conditions. In the current work, flow boiling experiments were conducted for MC cold plates with channel widths ranging from 61 μm to 330 μm and channel height ∼ 300 μm (hydraulic diameters from ∼ 100 μm to ∼ 337 μm) and a pin-fin array cold plate with fin size and inter-spacing ∼ 150 μm. Two working fluids, deionized water at sub-atmospheric pressure (∼ 25 kPa to 45 kPa) and HFE-7100 at ambient pressure, were tested respectively. High-speed visualization facilities were employed to help understand the rapid phase-change processes inside the flow passages. Pressure drop and heat transfer characteristics of the microchannel cold plates under various heat flux and flow rate conditions were recorded and analyzed as well as boiling fluctuations. Detailed visualization results will be presented in a separate paper [Tong et al., IMECE2007-42028].

Abstract:
Reticuloendotheliosis virus (REV) is an avian retrovirus that can cause immunosuppression, growth retardation and tumors. An attempt to define the extent of the economic damage to the poultry industry that it causes is discussed in this report. In addition to losses experienced by commercial laying flocks, reduced rates of hatchability and embryo developmental disorders were demonstrable due to vertical transmission of the virus. I. Eradication of REV In this project a comprehensive national program was applied for the eradication of REV from Israeli breeding stocks by the elimination of antibody-positive birds from the breeding program. The prevention of REV-infected breeders entering Israel was also implemented by serological examination of imported day-old chickens and turkeys for maternal antibody. At the same time commercial breeding flocks in Israel were surveyed routinely to measure the extent of environmental exposure to REV throughout Israel. II. Economic factors associated with vertical transmission on breeders and progeny It was observed that on some poultry farms exposure of breeding flocks to viral infection, if it occurs when the birds are immunocompetent, leads only to a seroconvertion event. In these flocks no differences were demonstrated between the performances of seronegative and seropositive birds. When the F1 generation was selected according to seronegativity of the parents, all the progeny were seronegative, indicating that tolerantly infected birds did not form a significant proportion of the parent flock. In sharp contrast, breeding flocks that became exposed to the virus about the point of lay or during the laying period, shed virus vertically for a brief period of time through the egg. Our epizootiological observations lead us to conclude that the progeny (laying pullets) becomes tolerantly infected and are immunosuppressed as they increase in age. Increased mortality and susceptibility to intercurrent diseases were recorded.

The environmental phenomenological properties responsible for the thermal variability evident in the use of thermal infrared (IR) sensor systems is not well understood. The research objective of this work is to understand the environmental and climatological properties contributing to the temporal and spatial thermal variance of soils. We recorded thermal images of surface temperature of soil as well as several meteorological properties such as weather condition and solar irradiance of loamy soil located at the Cold Regions Research and Engineering Lab (CRREL) facility. We assessed sensor performance by analyzing how recorded meteorological properties affected the spatial structure by observing statistical differences in spatial autocorrelation and dependence parameter estimates.

Abstract:
E-scooter use is increasing, and with it, the number of collisions involving e-scooters. The rapid rate of uptake of devices has resulted in a gap in the reference data available for collision investigators to make use of in reconstructing collisions, data which is commonly available for other collision types. The main aim of this study was to consider the capabilities of privately owned devices likely to be encountered in ‘real world’ collision scenarios and examine whether manufacturer-published data is realistic. Common characteristics and observations relevant to collision investigations were also recorded. A sample of donated, used devices was tested to determine the acceleration, deceleration and peak speed characteristics of different types of device
