Abstract:
Many areas of psychological science rely heavily on theoretical constructs, such as personality traits, attitudes, and emotions, and many of these measured constructs are defined by a continuum that represents the different degrees of the attribute. However, these continua are not usually considered by psychologists during the process of scale development and validation. Unfortunately, this can lead to numerous scientific problems, such as incomplete measurement of the construct, difficulties in distinguishing between constructs, and compromised evidence for validity. The purpose of the current article is to propose an approach for carefully considering these issues in psychological measurement. This approach, which we term continuum specification, is a two-stage process in which the researcher defines and then properly operationalizes the target continuum. Defining the continuum involves specifying its polarity (i.e., the meaning of its poles, or ends) and the nature of its gradations (i.e., the quality that separates high from low scores). Operationalizing the continuum means using this definition to develop a measure that (a) sufficiently captures the entire continuum, (b) has appropriate response options, (c) uses correct procedures for assessing dimensionality, and (d) accounts for the underlying response process. These issues have significant implications for psychological measurement.

Abstract:
I discuss various mathematical constructions that combine together to provide a natural setting for discrete and continuum geometric models of defective crystals. In particular, I provide a quite general list of ‘plastic strain variables’, which quantifies inelastic behaviour, and exhibit rigorous connections between discrete and continuous mathematical structures associated with crystalline materials that have a correspondingly general constitutive specification.

Abstract:
We have reviewed highlights of the research in trabecular bone biomechanics performed over the past 20 years. Results from numerous studies have shown that trabecular bone is an extremely heterogeneous material—modulus can vary 100-fold even within the same metaphysis—with varying degrees of anisotropy. Strictly speaking, descriptions of the mechanical properties of trabecular bone should therefore be accompanied by specification of factors such as anatomic site, loading direction, and age. Research efforts have also been focused on the measurement of mechanical properties for individual trabeculae, improvement of methods for mechanical testing at the continuum level, quantification of the three-dimensional architecture of trabecular bone, and formulation of equations to relate the microstructural and continuum-level mechanical properties. As analysis techniques become more sophisticated, there is now evidence that factors such as anisotropy and heterogeneity of individual trabeculae might also have a significant effect on the continuum-level properties, suggesting new directions for future research. Other areas requiring further research are the time-dependent and multiaxial failure properties at the continuum level, and the stiffness and failure properties at the lamellar level. Continued research in these areas should enhance our understanding of issues such as age-related bone fracture, prosthesis loosening, and bone remodeling.

Abstract:
(1) Background: Cloud storage is often required for successful operation of novel smart applications, relying on data produced by the Internet of Things (IoT) devices. Big Data processing tasks and management operations for such applications require high Quality of Service (QoS) guarantees, requiring an Edge/Fog computing approach. Additionally, users often require specific guarantees in the form of Service Level Agreements (SLAs) for storage services. To address these problems, we propose QoS-enabled Fog Storage Services, implemented as containerised storage services, orchestrated across the Things-to-Cloud computing continuum. (2) Method: The placement of containerised data storage services in the Things-to-Cloud continuum is dynamically decided using a novel Pareto-based decision-making process based on high availability, high throughput, and other QoS demands of the user. The proposed concept is first confirmed via simulation and then tested in a real-world environment. (3) Results: The decision-making mechanism and a novel SLA specification have been successfully implemented and integrated in the DECENTER Fog and Brokerage Platform to complement the orchestration services for storage containers, thus presenting their applicable value. Simulation results as well as practical experimentation in a Europe-wide testbed have shown that the proposed decision-making method can deliver a set of optimal storage nodes, thus meeting the SLA requirements. (4) Conclusion: It is possible to provide new smart applications with the expected SLA guarantees and high QoS for our proposed Fog Storage Services.

Abstract:
This paper proposes a version of the generalized method of moments procedure that handles both the case where the number of moment conditions is finite and the case where there is a continuum of moment conditions. Typically, the moment conditions are indexed by an index parameter that takes its values in an interval. The objective function to minimize is then the norm of the moment conditions in a Hilbert space. The estimator is shown to be consistent and asymptotically normal. The optimal estimator is obtained by minimizing the norm of the moment conditions in the reproducing kernel Hilbert space associated with the covariance. We show an easy way to calculate this estimator. Finally, we study properties of a specification test using overidentifying restrictions. Results of this paper are useful in many instances where a continuum of moment conditions arises. Examples include efficient estimation of continuous time regression models, cross-sectional models that satisfy conditional moment restrictions, and scalar diffusion processes.

Abstract:
The objective of this research was to demonstrate the validity of signal detection theory to the assessment (visual discrimination) of displayed color symbology. The area of application of the research results is in the design specification of color coded symbology to be overlayed on moving map, situational awareness displays. A symbol detection experiment was designed to determine how far apart, in CIE/UCS color space, symbol and background color must be in order for observers to detect that a symbol is present against the background. Six trained observers viewed a number of systematically varied symbol/background color combinations and were required to make one of six responses along a continuum from “symbol definitely present” to “symbol definitely not present”. The analyses of the d' and Beta signal detection measures yielded different patterns of results, suggesting that this paradigm was successful in separating the cognitive and sensory/perceptual factors associated with color-on-color target detection. In addition, the shape of the Receiver Operating Characteristic (ROC) curves indicated that the assumptions underlying the signal detection paradigm were met.

Abstract:
Model-based specification languages provide a means for obtaining assurance of dependability of complex computer-based systems, but provide little support for modelling and analysing fault behaviour, which is inherently probabilistic in nature. In particular, the need for a detailed account of the role of continuous probability has been largely overlooked. This thesis addresses the role of continuous probability in model-based specification languages. A model-based specification language (sGCL) that supports continuous probability distributions is studied. The use of sGCL and how it interacts with engineering practices is also explored. In addition, a re nement ordering for continuous probability distributions is given, and the challenge of combining non-determinism and continuous probability is discussed in depth. The thesis is presented in three parts. The first uses two case studies to explore the use of probability in formal methods. The first case study, on ash memory, is used to present the capabilities of probabilistic formal methods and to determine the kinds of questions that require continuous probability distributions to answer. The second, on an emergency brake system, illustrates the strengths and weaknesses of existing languages and provides a basis for exploring a prototype language that includes continuous probability. The second part of the thesis gives the formal de nition of sGCL's syntax and semantics. The semantics is made up of two parts, the proof theory (transformer semantics) and the underpinning mathematics (relational semantics). The additional language constructs and semantical features required to include non-determinism as well as continuous probability are also discussed. The most challenging aspect lies in proving the consistency of the semantics when non-determinism is also included. The third part uses a nal case study, on an aeroplane pitch monitor, to demonstrate the use of sGCL. The new analysis techniques provided by sGCL, and how they fit in with engineering practices, are explored.

Abstract:
This paper considers four approaches to ordinal predictors in linear regression to evaluate how these contrast with respect to predictive accuracy. The two most typical treatments, namely, dummy coding and classic linear regression on assigned level scores are compared with two improved methods; penalized smoothed coefficients and a generalized additive model with cubic splines. A simulation study is conducted to assess all on the basis of predictive performance. Our results show that the dummy based methods surpass the numeric at low sample sizes. Although, as sample size increases, differences between the methods diminish. Tendencies of overfitting are identified among the dummy methods. We conclude by stating that the choice of method not only ought to be context driven, but done in the light of all characteristics.

Full text
Abstract:
Continuous colormaps are integral parts of many visualization techniques, such as heat-maps, surface plots, and flow visualization. Despite that the critiques of rainbow colormaps have been around and well-acknowledged for three decades, rainbow colormaps are still widely used today. One reason behind the resilience of rainbow colormaps is the lack of tools for users to create a continuous colormap that encodes semantics specific to the application concerned. In this paper, we present a web-based software system, CCC-Tool (short for Charting Continuous Colormaps) under the URL https://ccctool.com, for creating, editing, and analyzing such application-specific colormaps. We introduce the notion of “colormap pecification (CMS)” that maintains the essential semantics required for defining a color mapping scheme. We provide users with a set of advanced utilities for constructing CMS’s with various levels of complexity, examining their quality attributes using different plots, and exporting them to external application software. We present two case studies, demonstrating that the CCC-Tool can help domain scientists as well as visualization experts in designing semantically-rich colormaps.

Abstract:
A novel compacted, torrefied, spherical biomass pellet, known as the "Q'Pellet", is aimed at overcoming the challenges of modern biomass pellets by building on the bene fits of torrefaction and utilizing the durability of a sphere. Pellets were made from both untreated hybrid poplar sawdust and material that had been partially torrefied at 250 C, allowing the torrefaction and pelletizing stages to be decoupled. A pelletizing die pre-heated to 280 C was successfully used to heat and torrefy room temperature raw and pre-torrefi ed material, greatly reducing the time required to produce each pellet. All Q'Pellets demonstrated 100% mechanical durability, and did not abrade during a tumbling can test or fracture during an impact resistance (drop) test. The gross calori fic value (GCV), ash and nitrogen content of pellets produced from raw hybrid poplar were 21.29+/-0.08 MJ/kg, 2.42+/-0.23 wt%, and <0.01 wt%, respectively. The GCV, ash and nitrogen content of pellets produced from pre-torre ed material were 21.25+/-0.34 MJ/kg, 3.58+/-1.11 wt%, and 0.42+/-0.03 wt%, respectively. The Q'Pellet was compared to biomass fuel speci fications in Europe and North America. The experiments performed herein provided an understanding of the material and process properties and limitations. Design speci fications for the development of a continuous pelletizing process were outlined. BGM Metalworks Inc has been hired by Queen's University to assist in the design and to fabricate the continuous pelletizing apparatus.

Full text
Abstract:
Large, software intensive systems are typically developed using a feature oriented development paradigm in which feature specifications are derived from domain requirements and features are implemented to satisfy such specifications. Historically, this approach has been followed in the telecommunications industry. More recently, in the automotive industry, features (for e.g. electronic stability control, collision avoidance etc.) are being developed as part of a software product line and a suitable subset of these features is integrated in an automobile model based on market requirements. Typically, features are designed independently by different engineering teams and are integrated later to create a system. Integrating features that are designed independently is extremely hard because the interactions between features are not understood properly and any incompatibilities may lead to costly redesign. In this thesis, we propose a framework for developing feature based systems such that even if features are incompatible, they can be integrated without redesign. Our view is that a feature based system consists of a base system and multiple features (or controllers), each of which independently advise the base system on how to react to an input so as to conform to their respective specifications. Such a system may reach a point of “conflict” between two or more features when they do not agree on a common action that the base system should perform. Instead of redesigning one or more features for resolving a conflict, we propose the novel notion of “conflicttolerance”, which requires features to be “resilient” or “tolerant” with regard to violations of their advice. Thus, unlike a classical feature, a conflicttolerant feature observes that its advice has been overridden, and takes this fact into account before proceeding to offer advice for subsequent behaviour of the base system. Conflict-tolerant features are composed using a priority order such that whenever a conflict occurs between two features, the base system continues with the advice of the higher priority feature. We guarantee that each feature is “maximally” utilized in that its advice is not taken only when there is a conflict with some higher priority controller. We show how to specify conflict-tolerant features for finite state, timed, and hybrid systems and also provide decision procedures for automated verification of finite state and timed systems. This provides a compositional technique for verifying systems which are composed of conflict-tolerant features. Our framework for developing feature based systems enables conflictresolution without redesign. The scope for reusing conflict tolerant features is significantly higher thus reducing design and verification effort.

Abstract:
<p>Koror Babeldaob Bridge, also called Koror Babelthuap Bridge or simply Koror Bridge, connects the islands of Koror and Babeldaob in the Republic of Palau. The design of the bridge began in 1974 and was based on the prevailing AASHO Standard Specifications at that time and was supplemented by ACI and CEB-FIP design recommendations on an as-needed basis. When the Koror Bridge was opened to traffic in April 1977, it was the world's longest concrete girder span. A few years later, the bridge began to deflect more than had been anticipated. The owner commissioned a Japanese engineering firm in 1985 and then a US engineering firm in 1993 to conduct in-depth investigations of the structure. Both firms came to the same conclusion that the bridge was structurally safe and that the excessive deflection was an unexplainable phenomenon. Nevertheless, in order to improve the driving quality of the bridge deck, the owner decided to repair the bridge. The repair scheme made changes to the structural system and added a large amount of post-tensioning force to the bridge. Unfortunately, less than three months after the repair, late in the afternoon on 26 September, 1996,nineteen and a half years after it was opened to traffic, the bridge collapsed. Thereafter, most of the documents were sealed as a result of litigation between the various parties and the debris was cleared. For a long time, it was impossible to study the facts surrounding the bridge's collapse. Only recently, through continuous probing by a group of engineers, were these documents made accessible to researchers.</p>

Abstract:
This article explains the use of factor analysis types of models to develop measures of latent concepts which were then combined with causal models of the underlying latent concepts. In particular, it offers an overview of the classic structural equation models (SEMs) when the latent and observed variables are continuous. Then it looks at more recent developments that include categorical, count, and other noncontinuous variables as well as multilevel structural equation models. The model specification, assumptions, and notation are covered. This is followed by addressing implied moments, identification, estimation, model fit, and respecification. The penetration of SEMs has been high in disciplines such as sociology, psychology, educational testing, and marketing, but lower in economics and political science despite the large potential number of applications. Today, SEMs have begun to enter the statistical literature and to re-enter biostatistics, though often under the name ‘latent variable models’ or ‘graphical models’.

The Metaphysics of Notation (2008) is a 72-foot-wide, hand-drawn pictographic score divided into twelve continuous panels.1 It is accompanied by no instruction regarding its interpretation. The work aspires to elicit a musical response from a performer, but despite its profusion of concrete, detailed glyphs it advocates nothing specific about the nature of their aural realization. Furthermore, I heard no sound in my head while composing the piece. This is a radical departure from the approach to composition I was taught, in which the composer’s job is to imagine—preferably with exacting resolution—a sound object, and then, through the deft application of the most relevant notation (whether traditional or invented—but if the latter, surely a defined one) to produce a specification from which a performer (burdened or invigorated by a marginal or essential role as interpreter) can realize this imagined sound....

Abstract:
Global warming and climate change coincide in their main causes, the massive emission of greenhouse gases, which retain heat in the atmosphere and on the earth's surface through the so-called greenhouse effect. The generation of electricity by means of fossil fuels is an important emitter of greenhouse gases (CO2, CH4, N2O), and halogenated compounds containing F, Cl, and Br. With the purpose of contributing to the construction of viable solutions to the current energy situation of the country and in the foundation of a sustainable future, the use of solar energy for the generation of electricity by means of solar panels represents an option. The purpose of this study is to describe and control the solar cell protection material Ethylene-Vinyl-Acetate (EVA), as a contribution to the Quality Assurance of solar panels, since the function of this material is essential for the protection of solar cells, which are a vital part of the solar panel. The tests performed were: Gel content, adhesion test, and durability tests. The results obtained were within specification according to IEC 61215. From this work it is concluded that it is important to continue testing the whole process and components of the solar panels in order to guarantee the useful life of the finished product, as well as to contribute to sustainable development.

Abstract:
AbstractAccording to the laws of software evolution, the size and complexity of software systems continue to increase over time and, simultaneously, if not maintained rigorously, the quality decreases. Quality degradation typically happens due to changes in policies, regulations, and industry requirements, which, in turn, complicates compliance management over time. Among the key challenges in managing the evolution of software are the modelling and the enforcement of compliance rules. Moreover, the gap between compliance experts and software engineers has worsened the problem. The topology and orchestration specifications for cloud applications (TOSCA), which is an OASIS standard, has the potential to offer a relief by enabling different levels of abstractions for modeling and enforcing compliance policies. This work aims at investigating the potential of using TOSCA service templates for modelling and enforcing non-functional requirements and policies. Then, it proposes an approach that maximizes involvement of stakeholders in modeling and auditing such requirements and policies. Findings can help enterprises and policy makers achieve better governance and compliance on software services.

Abstract:
Compliant mechanism design inherently requires certain specified displacement boundary conditions to be satisfied. Obtaining realistic solutions for such problem types often becomes a challenge as the number of displacement boundary condition specifications increases. Typically, related failures are attributed to the numerical nature of the solution process. Little attention has been given to the fundamental understanding of the deformation behavior of flexible continuum with respect to its limits of mobility or reach. This paper strives to provide an insight into this aspect of compliant mechanism design. To assist a designer with the specification of realistic and achievable requirements, the concept of characteristic deflection domain has been proposed in the past. This paper systematically develops the characteristic deflection domain for a variety of compliant segment types. The pseudo-rigid-body model (PRBM) representation is utilized for determining the lower and upper boundaries of the deflection domain. The paper further investigates the mobility characteristics of compliant mechanisms comprised of multiple segment types. Case studies are presented that help exemplify the use of the characteristic deflection domain plots. The results suggest that the number, type, and orientation of the compliant segments have a significant effect on the mobility of compliant mechanisms. Thus, care must be exercised by the designer when specifying free-choices/boundary conditions in compliant mechanisms synthesis and analysis.

Abstract:
This paper presents results from two different Finite Element (FE) pipeline ice-scour models employing pipe and shell elements that incorporate large deformations and metal plasticity. The main objective of this paper is to investigate the effects and implications of some of the main pipeline design parameters on the response of the pipeline determined by using Winkler models and soil displacements that are based on an empirical scour function commonly used in recent literature. The current model is two dimensional in terms of deformed pipe geometry and incorporates temperature and pressure stiffness effects. A detailed study of the soil displacements underneath and around the scour and a three-dimensional continuum based ice-soil-pipe interaction model is being presented in a different paper. The paper discusses the limitations and implications of the Winkler modeling and compares results obtained using different Winkler spring models. It illustrates the effects of pipe temperature (and pressure), pipe burial depth, and scour width. A comparison of pipe response using shell and pipe elements is also presented. This paper presents results from the FE models for a typical gathering pipeline. The pipe is taken to be a 16 inch diameter and 0.75 inch wall thickness API 5L X65 Specification line pipe.

Abstract:
This paper presents a methodology for using sensor-generated data from multi-degree-of-freedom mechatronic loading systems to identify the elastic moduli of a composite laminate material system. This is done not to demonstrate the method itself but rather to study how various features of the experimental and analytical procedure can affect the identification process. The analytical formulation of the identification problem is described first given the geometry of a test specimen and a loading path. The concept of singular value decomposition (associated with pseudo inversion factorization) is introduced for the purpose of parameter identification as it applies to the elastic moduli. Also, the concepts of distinguishability and uniqueness are introduced to evaluate the quality of parameter identification. The analysis is performed on a continuum model basis in order to evaluate if the proposed technique can work for specimens of arbitrary shape. Elastic coefficients were identified using pseudo-experimental (numerically synthesized) data created by finite element analysis (FEA) and the effect of the introduced distinguishability and uniqueness on the identification was investigated through several numerical examples. The effects of the form of the chosen multidimensional loading path(s) and the shape of the specimen on various features of the inverse identification process related to the elastic moduli parameter estimation are also determined. The results of the numerical studies demonstrate the efficacy of the proposed methodology and suggests subsequent avenues for optimizing the specification of the loading path both a priori and in real-time.

Abstract:
Worldwide oil and natural gas reserves can be classified as either sweet or sour service. The sour service classified oil and natural gas reserves contain some level of H2S making the product flowing through a steel pipeline corrosive. Due to this, the majority of the oil and natural gas reserves that have been drilled are of the sweet service nature. However as demand continues and supplies change, many of the remaining oil and natural gas reserves contain the H2S component and are of a sour service nature. These oil and natural gas reserves containing the H2S component through a corrosion mechanism will allow for diatomic hydrogen — in the presence of moisture — to disseminate to monatomic hydrogen and diffuse into the pipeline steel microstructure. Depending on the microstructure and level of cleanliness the monatomic hydrogen can become trapped at areas of high residual stress, recollect to diatomic hydrogen and creating partial pressures that exceed the tensile strength of the steel resulting in cracking. Therefore transmission pipelines are being built to transport sour service oil or natural gas requires steels with hydrogen induced cracking (HIC) resistance. Alloy designs, steel making processing, continuous casting, plate or strip rolling, pipe forming, and last not least corrosion testing are all key components in producing pipeline steels that are resistant to HIC applications and meeting the NACE TM0284 specifications. However, producing steels that have good HIC performance do not necessarily meet other mechanical property requirements such as strength and YT ratios. Balance has to be achieved to meet not only the HIC requirements but the other required mechanical properties. Mastering this complex HIC process poses a serious challenge to pipe producers and their primary material suppliers. The capability of producing HIC steel grades according to critical specifications and/or standards clearly distinguishes excellent steel producers from good steel makers. This paper will discuss the basics of the hydrogen induced cracking phenomenon, the requirements of the NACE TM0284 specification and give guidelines for steel production of API pipeline steels that not only can meet the specification requirements the NACE testing but also fulfill the other mechanical property requirements.

Abstract:
This report describes the results of technical analysis, field tests, and laboratory tests that were performed for LED highway lighting options by the Energy Efficiency and Reliability Center (EERC) at Purdue University Northwest for the Indiana Department of Transportation (INDOT). This effort was conducted over the past 3 years to evaluate and test the technology and viability of using modern highway lighting technology to enhance energy efficiency, safety, security, and economic development of communities and roadways. During the testing period there was a continuous discussion between INDOT and EERC regarding the laboratory and field testing of INDOT approved luminaires submitted by vendors. There were multiple discussions with INDOT and vendors regarding the individual details and issues for the 29 luminaires that were tested. A comparison study was conducted by EERC of the various alternatives and comparison to currently installed luminaires. Data was collected for field tests of the luminaires by EERC and INDOT personnel for the luminaires. Field data was evaluated and compared to lighting models using vendor supplied ies data files. Multiple presentations were made at 3 separate Purdue Road Schools regarding the results and procedures of the testing program by EERC in conjunction with INDOT. A total of 22 final reports, considered confidential by INDOT, for individual vendor luminaires have been prepared as part of this effort. These reports were submitted sequentially to INDOT as testing was completed during the course of this effort. A total of 29 luminaires were tested. Some luminaire testing was terminated during testing due to design issues or vendor requests. All testing was summarized in the INDOT specification sheet attached to each report. Observations regarding the consistency of the supplied test luminaire with the requirements of Section 7.2 of the INDOT test procedure “Procedure for evaluation and approval list requirements for solid state ballasted luminaires ITM 957-17P” is provided in the Appendix to the report for each luminaire. Details regarding how these tests were performed and the respective associated evaluation of performance and reliability are provided in the report. This effort included: consideration of published and vendor information; appraisal of products consistent with national industry standards; review of physical design, thermal performance; laboratory testing of photopic performance, reliability, life cycle data and characteristics, and power characteristics; technical and probabilistic risk studies; and field testing and analysis of LED light sources including comparison to currently installed conventional light sources. Assistance in preparing INDOT standards for highway lighting was provided on multiple occasions.

Abstract:
In 2015, the Natural Sounds and Night Skies Division (NSNSD) received a request to collect baseline acoustical data at Mesa Verde National Park (MEVE). Between July and August 2015, as well as February and March 2016, three acoustical monitoring systems were deployed throughout the park, however one site (MEVE002) stopped recording after a couple days during the summer due to wildlife interference. The goal of the study was to establish a baseline soundscape inventory of backcountry and frontcountry sites within the park. This inventory will be used to establish indicators and thresholds of soundscape quality that will support the park and NSNSD in developing a comprehensive approach to protecting the acoustic environment through soundscape management planning. Additionally, results of this study will help the park identify major sources of noise within the park, as well as provide a baseline understanding of the acoustical environment as a whole for use in potential future comparative studies. In this deployment, sound pressure level (SPL) was measured continuously every second by a calibrated sound level meter. Other equipment included an anemometer to collect wind speed and a digital audio recorder collecting continuous recordings to document sound sources. In this document, “sound pressure level” refers to broadband (12.5 Hz–20 kHz), A-weighted, 1-second time averaged sound level (LAeq, 1s), and hereafter referred to as “sound level.” Sound levels are measured on a logarithmic scale relative to the reference sound pressure for atmospheric sources, 20 μPa. The logarithmic scale is a useful way to express the wide range of sound pressures perceived by the human ear. Sound levels are reported in decibels (dB). A-weighting is applied to sound levels in order to account for the response of the human ear (Harris, 1998). To approximate human hearing sensitivity, A-weighting discounts sounds below 1 kHz and above 6 kHz. Trained technicians calculated time audible metrics after monitoring was complete. See Methods section for protocol details, equipment specifications, and metric calculations. Median existing (LA50) and natural ambient (LAnat) metrics are also reported for daytime (7:00–19:00) and nighttime (19:00–7:00). Prominent noise sources at the two backcountry sites (MEVE001 and MEVE002) included vehicles and aircraft, while building and vehicle predominated at the frontcountry site (MEVE003). Table 1 displays time audible values for each of these noise sources during the monitoring period, as well as ambient sound levels. In determining the current conditions of an acoustical environment, it is informative to examine how often sound levels exceed certain values. Table 2 reports the percent of time that measured levels at the three monitoring locations were above four key values.
