In this study, the settlement behavior of the piled raft foundations resting on overconsolidated clays under uniform loading, is investigated for different pile configurations and load levels. A total of 100 plane &ndash
strain and three &ndash
dimensional finite element analyses are carried out and the results of these analyses are compared both with each other and with the results presented by Reul &
Randolph (2004). The material parameters used in the analysis are selected mainly referring to the previous studies cited above on the same subject and slight modifications are made for convenience in the analysis. The analysis method and the applied pile configurations and load levels are directly taken from the reference study, excluding the soil model employed. A drained Mohr &ndash
Coulomb failure criteria is employed in the analysis of this study in modeling the soil instead of an elastoplastic model which was used in the analysis of the reference study. The results are evaluated for the average and differential settlements of the foundations and it is seen that
although the average and differential settlements calculated in this study are not always very close to the values calculated in the reference study, the calculated settlement reduction factors due to piles (especially for the average settlements) compared well with the findings of the reference study for all pile configurations and load levels considered. Based on this, a new approach is suggested to estimate the average settlements of the piled raft foundations. Moreover, correction factors are recommended in order to estimate the average settlements of the piled rafts by directly using the programs employed throughout the thesis.

This thesis examines the difference between the extracted cyclical components of some macroeconomic time series using four popular detrending methods HP, BK, CF and FOD. We use different approaches to compare their differences. A standard examination of the cyclical component is applied. We also take a frequency domain approach and examine the sample spectra for each cycle. Moreover, impulse responses and the correlation between the cyclical components extracted by each detrending method are studied. We conclude that for quarterly data HP, BK and CF produce similar cycles. However, when considering annual data the HP diverges from the other filters. The FOD extracts cycles that are not similar to those of the other three examined filters.

Natural Language Understanding (NLU) has been one of the longest-running and the most challenging areas in artificial intelligence. For any natural language comprehension system having a basic understanding of entities and concepts is a primary requirement. Comparison, where we name the similarities and differences between entities and concepts, is a unique cognitive ability in humans which requires memorizing facts, experiencing things and integration of concepts of the world. Clearly, developing NLU systems that are capable of comprehending comparison is a crucial step forward in AI. In this thesis, I will present my research on developing systems that are capable of comprehending comparison, through which, systems can learn world knowledge and perform basic commonsense reasoning.

The purpose of this research was to design a method for the detailed comparison of processes. People already do process measurement and compare these measurements to internal or regulatory standards. The innovation in this thesis is the development of an algorithm for process comparison that accommodates any process, responds to any kind of semantic junction in the process model, deals with uncertain process data, and compares all or part of a process. This is done by the activity-by-activity comparison of data and measurements from an actual process to a model of a process.
IDEF3 diagrams were used for process modeling, a modified PERT network technique was used for process comparison, and the technique incorporated fuzzy data and metric comparison.
Solutions of practical problems showed that the algorithm does not have any limitations for process comparison. While the test data were for time performance only, other metrics can easily be accommodated, such as cost, quality, human resource or energy.

Streszczenie:

How mental representations are constructed and how they evolve are central problems for cognitive science. Representation decisions help determine what computations are hard or easy. Structured, relational representations are a hallmark of human cognition. Developmental studies show that children do not perform as well as adults in tasks that require noticing relational similarity. What drives this development? Gentner and her colleagues have argued that comparison and language are two forces driving this change. This thesis explores these ideas further by presenting a computational model of forced choice tasks to illuminate the roles of comparison and language in driving representational change.

The model simulates the following roles of comparison. First, comparison can be used to make selections in forced-choice tasks. Second, comparisons from recent positive experiences are assimilated as interim generalizations which are retrieved for subsequent tasks and influence encoding by highlighting relevant structure. Third, comparisons suggest opportunities for re-representation. Finally, verifying candidate inferences resulting from a comparison provides a way to augment encodings with background knowledge, thus enriching representations. The model simulates the role of language in facilitating the creation and enrichment of generalizations as follows. When two objects are given the same label, the model compares them. This leads to an interim generalization associated with that label, enriched with commonalities from background knowledge.

We tested these hypotheses by extending the Companion cognitive architecture and simulating three developmental studies. To reduce tailorability, the visual stimuli were provided as sketches and the objects were labeled using simplified English. The model was evaluated by comparing its behavior and learning trajectory to that of children in the developmental studies. The performance of the model in the simulations provide evidence for the claims of this thesis.

The purpose of this study is to aide web developers in choosing which component library to integrate with their web based Angular project. Angular is a new platform and many of the existing component libraries are still under active development, or were only recently released, making it difficult for developers to know which component library would be the best fit for their project. This study reviews many factors which would influence a developer’s decision on which library to use including: the size of the community, number of components available, quality of documentation, payload size increase, and load time performance. This study proves that the most popular projects aren’t the most performant and are lacking key features, while some much less popular libraries are performing better and have a better set of components. Developers looking for the best combination of performance and features should consider ngx-bootstrap or Angular Material Design Lite.

Streszczenie:

This programme of research is concerned with a direct comparison between the ways in which we respond to, and become aware of, subliminal and psi stimuli. I define subliminal percepts as those produced by sensory stimulation below the awareness threshold; psi "percepts", i.e. telepathy, clairvoyance and precognition, are those occurring in the absence of any physical stimulus. Initially a preliminary investigation was run to choose suitable target stimuli and to ascertain the correct subliminal volume. Then an exploratory study was run in which 10 participants undertook six Ganzfeld sessions each. The Ganzfeld technique induces the hypnagogic state and is a successful and well-researched design in parapsychology. Besides measuring levels of awareness to the stimuli, affective, physiological and personality factors were assessed. In the follow-up study, the basic design and targets were refined, and more extensive psychological tests were included; a semantic differential test, a state of consciousness report, and cognitive flexibility tests. The final study was run in order to assess whether the basic findings would generalise to a wider segment of the population. Results from the exploratory and follow-up studies indicate that, at the cognitive level of response, the psychological process of achieving awareness of the target is very similar for both phenomena. The final study indicated that awareness of subliminal stimuli is possibly relatively greater under certain circumstances. All three studies indicated that both phenomena are affected by factors such as attitude and personality in a similar manner.

Streszczenie:

In robot navigation, and image content searches reliable salient features are of pivotal importance. Also in biometric human recognition, salient features are increasingly used.

Regardless the application, image matching is one of the many problems in computer

vision, including object recognition.

This report investigates some salient features to match sub-images of different images.

An underlying assumption is that sub-images, also called image objects, or objects, are

possible to recognize by the salient features that can be recognized independently.

Since image objects are images of 3D objects, the salient features in 2D images must be

invariant to reasonably large viewing direction and distance (scale) changes. These

changes are typically due to 3D rotations and translations of the 3D object with respect to

the camera. Other changes that influence the matching of two 2D image objects is

illumination changes, and image acquisition noise.

This thesis will discuss how to find the salient features and will compare them with

respect to their matching performance. Also it will explore how these features are

invariant to rotation and scaling.

Variability in complex systems offering rich set of features is a seriouschallenge to their users in term of flexibility with many possible variants fordifferent application contexts and maintainability. During the long period oftime, much effort has been made to deal with these issues. An effort in thisregard is developing and implementing different variability modelingtechniques.This thesis argues the explanation of three modeling techniques namedconfigurable components, feature models and function-means trees. The maincontribution to the research includes:• A comparison of above mentioned variability modeling techniques in asystematic way,• An attempt to find the integration possibilities of these modelingtechniques based on literature review, case studies, comparison,discussions, and brainstorming.The comparison is based on three case studies each of which is implemented inall above mentioned three modeling techniques and a set of generic aspects ofthese techniques which are further divided into characteristics. At the end, acomprehensive discussion on the comparison is presented and in final sectionsome integration possibility are proposed on the basis of case studies,characteristics, commonalities and experience gained through theimplementation of case studies and literature review.

Streszczenie:

Points-to analysis is a static program analysis which computes possible reference relations between different parts of a program. It serves as input to many high-level analyses. Points-to analyses differ, among others, in flow- and context-sensitivity, program representation, and object abstraction. Most program representations used for points-to analysis are sparse representations which abstract from, e.g., primitive data types and intra-procedural control-flow. Thus, a certain degree of information is sacrificed for compact program representation, which results in scalable performance. In this thesis, we present a framework which allows building different versions of Points-to SSA (P2SSA), a sparse, Memory SSA based program representation. Distinct instantiations of P2SSA contain different levels of abstraction from a program's full representation. We present another framework which allows running Points-to analyses on these program representations. We use these two frameworks to instantiate different versions of P2SSA and compare them in terms of analysis precision and execution time.

This study aims to find out teachers&rsquo
and learners&rsquo
perception of language learning strategies (LLSs). Three psycho-social variables regarding the teachers&rsquo
use of strategy instruction at BaSkent University were considered: 1. Level of awareness of language learning strategies 2. Beliefs in the effectiveness of language learning strategies 3. Ease of strategy instruction. These results were compared with the students&rsquo
reported use of LLSs to increase our awareness of students&rsquo
strategy use and needs so that teachers would be able to help learners facing problems in learning English. This study employed both qualitative and quantitative research tools. The relevant data were obtained by means of two questionnaires: a teacher and a student version of Strategy Inventory for Language Learning (SILL, Oxford, 1990), and a semistructured interview. A total of 70 teachers teaching at the English language department of BaSkent University and 100 students studying in the same department were involved in the study. Data collected from the questionnaire were analyzed quantitatively by employing descriptive statistics, such as frequencies, percentages, means, and standard deviations. Content analysis was performed to analyze the interview data. v The results of the study suggest that for most of the items in the strategy inventory, if the teachers are aware of learning strategies, believe in the effectiveness of LLSs instruction and find them easy to apply in the classroom, they may use them more often in their classes. Furthermore, in variance analysis, the only variable that made a difference in teachers&rsquo
perceptions of LLSs was found to be the level of education, Finally, when the teachers&rsquo
and students&rsquo
frequency of LLSs use was compared, it was found out that teachers reported a higher frequency of LLSs use than their learners. However, there was a great similarity between the two parties in terms of frequency of strategy use in the most and least preferred strategy categories. It is essential to find the reasons for the difference in the frequency of LLSs among the two parties before planning a LLSs training.

This thesis is a comparison of the philosophical systems of Zen Buddhism, which is an Eastern Philosophy, with Ludwig Wittgenstein&rsquo
s philosophical studies, who is an extraordinary name of the Western Philosophy in the 20th century. The history and sources of Zen Buddhism were given with its adoption in the use of language and arts. Besides, this study exemplifies the philosophy of Zen Buddhism with the examples from the life story of Wittgenstein. The thesis is written with a full awareness of the sensitivity of comparing different systems which always embody counterexamples and speculations. This is the reason why speculative ideas and resources were deliberately ignored. The aim is to contribute the cultural life of Turkey by taking such a subject to the academic milieu. Moreover, Turkey is the passage of the East and the West both geographically and culturally. There are resemblances between Zen and Wittgenstein by means of method and the useof language. Furthermore, it was given the names of the books that Wittgenstein read and the philosophers who influenced Wittgenstein. The parallels between Zen and Wittgenstein are justified.

Streszczenie:

The Clovis caches in this study consist of assemblages of tools left behind in an area either for future use or as ritual offerings. Clovis caches are the earliest of such assemblages known in North America. This research specifically examines a sample of four caches: East Wenatchee from Douglas County, Washington; Anzick from Park County, Montana; Simon from Camas County, Idaho; and Fenn, inferred to be from Sweetwater County, Wyoming. The artifact types in this study include fluted points, bifaces, blades, flakes, bone rods, and miscellaneous. The variables used in this study include maximum length, mid-length and maximum width, thickness, (length*width*thickness)/1000, length/width, and width/thickness; using millimeters as the basic measurement unit. This study utilizes five methods in the study of the caches: descriptive statistics, factor analysis, cluster analysis, correspondence analysis, and geoarchaeology. The descriptive statistics reveal the most prominent trends that become more apparent in the subsequent statistical analyses. Such trends include East Wenatchee containing the largest points but the smallest bifaces, Anzick and Simon having significant biface variation, Fenn tending to be average in most respects, and bone rods being larger in East Wenatchee than they are in Anzick. The factor analysis explores the relationships between the variables and assigns them to larger components. Length, width, thickness, and length*width*thickness comprise the size component, and length/width and width/thickness make up the shape component. The cluster analysis examines the artifacts within each site and between all sites to identify the most appropriate grouping arrangements based on similarities in artifact measurements. The general results show that fluted points form three clusters according to size more than shape, bifaces are highly variable but have no obvious clusters, and bone rods form three clusters with the first two being strictly divided by site. The correspondence analysis shows that the differences in count data between caches appear to relate to the geographic distances between them. Finally, geoarchaeological analysis posits that East Wenatchee has no discernable pit feature, Anzick contains only one human burial, Simon was not deposited in a pluvial lake, and Fenn would have been shallowly buried but was probably disturbed by erosion.

After many decades of being considered useless and often destroyed wetlands have become valued for the many functions they provide. To make informed wetland management decisions biologists have to develop practical, rapid, and inexpensive ways to assess biological conditions and functions. Ideally these assessment methods have to measure more than one attribute of the wetland to represent the overall condition of the biological community. For this project I conducted field assessments at mitigation sites in Pembroke Pines, Florida, to see how the newest method used in the State of Florida, the Uniform Mitigation Assessment Method (UMAM), compared to the older Wetland Rapid Assessment Procedure (WRAP), and a Wildlife Survey (WS). The assessments determined at what level the mitigation sites of this study functioned, and were than repeated over a thirteen month period to account for seasonal fluctuations. For each assessment method a worksheet was completed, which along with available background information for the sites, was used to determine the value, and function provided by the wetlands. The three methods were then compared using eleven evaluation criteria I developed. Based on my results UMAM was the best assessment method tested saving the most acreage while integrating risk factors and time lag.

Gran och tall är de vanligaste barrträden i Sverige. Tack vare import från andra länder har kontakt med andra träslag som inte växer i Sverige uppstått. Dessa nya träslag väcker ett intresse att vilja skapa fasader med de nya träslagen. Studiens syfte är att jämföra behandlade träfasader med två obehandlade ädelträslag gällande kostnad och beständighet. Behandlingarna som har studerats är järnvitriol samt akrylatfärg och ädelträslagen som valts är jättetuja (Thuja Plicata) och sibirisk lärk (Larix Sibirica). Då det vanligaste underlaget för akrylatfärg är gran och furu har även dessa träslag behandlats i rapporten. Målet är att komma fram till vilket ädelträ som är mest lämpligt i förhållande till en behandlad fasad. Studien har genomförts genom att studera litteratur och dokument samt intervjua en arkitekt, en bebyggelseantikvarie, en forskare, en färghandlare och en produktchef från en träleverantör. Respondenternas svar vid intervjuerna behandlar bland annat osäkerheten vid att använda ett relativt nytt träslag i Sverige som fasad. Flera av dem tar även upp att en obehandlad träfasad kommer att få färgförändringar med tiden och det är svårt på att förhand veta vilken färg fasaden kommer att anta och om den åldras jämnt. Järnvitriol är en behandling som ger träet ett väderpinat uttryck snabbare än den naturliga patineringen. Dock skyddar behandlingen inte träet till skillnad från akrylatfärgen som ger träet ett extra skydd mot yttre påverkan. Skillnaden mellan ceder och lärk är stor i vissa avseenden, bland annat är det ena träslaget mer sprickbenäget och har kortare livslängd. Fördelen med en obehandlad träfasad, jämfört med en fasad målad med akrylatfärg, är att en rätt konstruerad obehandlad träfasad kräver väldigt lite underhåll till skillnad från akrylatfärgens underhållsintervall på 1015 år. Kostnadsmässigt är det ganska stor skillnad beroende på vilken typ av fasad som väljs. Det viktiga för en träfasad är att den får möjlighet att torka ut ordentligt efter nederbörd. Ett takutsprång är även en fördel både vad gäller en behandlad och obehandlad fasad. Träslagen rapporten behandlar är alla lämpliga att använda som fasad men då de har olika egenskaper passar behandlingarna olika bra med respektive träslag.

Network visualizations have been used for quit long time. Different disciplines use this visualization to compare a given dataset. Identifying better comparison approach that is used for information visualization is indispensable both for the people who are using it and for developers who are looking for a better way of visualizing huge data. In this thesis a task based approach has been used to analyze two different network comparison approaches namely Juxtaposition (showing different objects compared in separate space or time) and Superposition (overlaying objects in the same space). Thirty students at Linnaeus University have participated in the questionnaire to evaluate the usability of the two approaches. SPSS tool is used to analyze the data collected from the participants and the result explicitly indicates that there is no significant variation between Juxtaposition and Superposition comparison approaches. The result can be used as a recommendation for domain specific professionals and developers in their quest for better network comparison for their audience.

Streszczenie:

Trend estimation is important in many fields, though arguably the most important applications appear in ecology. Trend is difficult to quantify; in fact, the term itself is not well-defined. Often, trend is quantified by estimating the slope coefficient in a regression model where the response variable is an index of population size, and time is the explanatory variable. Linear trend is often unrealistic for biological populations; in fact, many critical environmental changes occur abruptly as a result of very rapid changes in human activities. My PhD research has involved formulating methods with greater flexibility than those currently in use. Penalized spline regression provides a flexible technique for fitting a smooth curve. This method has proven useful in many areas including environmental monitoring; however, inference is more difficult than with ordinary linear regression because so many parameters are estimated. My research has focused on developing methods of trend detection and comparing these methods to other methods currently in use. Attention is given to comparing estimated Type I error rates and power across several trend detection methods. This was accomplished through an extensive simulation study. Monte Carlo simulations and randomization tests were employed to construct an empirical sampling distribution for the test statistic under the null hypothesis of no trend. These methods are superior over smoothing methods over other smoothing methods of trend detection with respect to achieving the designated Type I error rate. The likelihood ratio test using a mixed effects model had the most power for detecting linear trend while a test involving the first derivative was the most powerful for detecting nonlinear trend for small sample sizes.

In this thesis a comparison of PSSE (Power System Simulator for Engineering) fromSiemens and PowerFactory from DIgSILENT is done. The two tools can be used inmany ways to analyze power system stability and behavior. This thesis cover the useof load flow and dynamic stability simulation. Different modeling and definitions areused by the tools why differences in the results may occur. A network defined in PSSEcan be imported to PowerFactory. The thesis presents what is need to be consideredwhen moving a network from PSSE to PowerFactory. The work is also done to test ifit is possible to have identical simulation results. The report indicates that it ispossible to have identical load flow. The dynamic simulation will have similar behaviorif the correct set-up is made. The generators use different modeling and can be testedin a step response. By tuning the generator parameters according to the stepresponses, will have a positive impact to the dynamic simulation results.

Thin films that are functionally gradient improve the mechanical properties of film-substrate layered materials. Mechanical properties of such materials are found by using indentation tests. In this study, finite element models are developed to simulate the indentation test. The models are based on an axisymmetric half space of a specimen subjected to spherical indentation. The film layer through the thickness is modeled to have either homogeneous material properties or nonhomogeneous material properties that vary linearly. Maximum indenter displacement, and maximum normal and shear stresses at the interface are compared between the homogeneous model and the nonhomogeneous model for pragmatic contact length to film thickness ratios of 0.2 to 0.4, and film to substrate moduli ratios of 1 to 200 to 1. Additionally, a coefficient is derived from regression of the stress data produced by these models and compared to that used to define the pressure field in the axisymmetric Hertzian contact model. The results of this study suggest that a displacement boundary condition to an indenter produces the same results as a pressure distribution boundary condition. The critical normal stresses that occur between modeling a film as a nonhomogeneous and as a homogeneous material vary from 19% for a modulus ratio of 2.5:1 to as high as 66% for a modulus ratio of 200:1 indicating that the modeling techniques produced very different maximum normal stresses. The difference in the maximum shear stress between the nonhomogeneous and the homogeneous models varied from 19% for a 2.5:1 modulus ratio to 57% for the 200:1 modulus ratio but reached values as low as 6% for the 50:1 modulus ratio. The maximum contact depth between the nonhomogeneous and the homogeneous models varied from 14% for the 2.5:1 case to as much as 75% in the 200:1 case. The results from the reapplication of the pressure field derived from the regression coefficients and the R2 values from these regression models indicate the correctness of the regression model used as well as its ability to replicate the normal stresses in the contact area and maximum indenter displacements in a FEA model for both the homogeneous and the nonhomogeneous models for modulus ratios ranging from 2.5:1 to 200:1. The agreement between the regression based coefficients and the force based coefficients suggests the validity for the use of the theoretical axisymmetric Hertzian contact model for defining the pressure field in the contact area and displacements for both the homogeneous case and the nonhomogeneous case for the considered film to substrate moduli ratios and contact length to film thickness ratios.

Database and database technology are having a major impact on the growing use of computers. The rising popularity of database systems for the management of data has resulted in an increasing number of systems. As the number grows, the difficulty in choosing the system which will best meet the requirements of a particular application also increases. Knowing how to choose the correct one for a given application is important.The purpose of this thesis is to compare two very commonly used Database Management Systems (ORACLE and RDB) at Ball State University by describing and listing the advantages of each of them as well as their weaknesses, giving a comprehensive study of their performances, user friendliness, limits, and to aid users and managers in obtaining a deeper knowledge of these two systems.

Databases and database technology are having a major impact on the growing use of computers. It is fair to say that databases are playing a critical role in almost all areas where computers are used, including business, engineering, medicine, law, education, and library science, to name a few.At Ball State University, databases are very widely used among faculty, staff, and students. The common commercial database management system (DBMS) used in the university is ORACLE. Due to the extensive use of the system and the availability and easy access to alternative systems such as RDB/VMS, a comparative research is in order.This thesis is a comprehensive comparison between the two systems. It covers the differences in design, SQL codings, and the use of host programming language such as FORTRAN. It concentrates on the differences in memory usage, execution time, as well as the CPU time needed to precompile, link, and run.

A widely used access control mechanism is the password. Passwords are normally composed of a meaningful detail, such as a name of a person or a sequence of numbers such as birthdate. Any person attempting to gain unauthorized access to a system might need only to look at a personnel record or associate with the person holding the desired password in order to discover the password. Therefore, there is a compromise between user memorability and security of a system. Exploration into other methods of user authentication and access control is desired to discover a better alternative to the traditional password system. The alternative are system-generated passwords, pronounceable passwords, passphrases, cognitive passwords and authentication by word association. These methods are discussed and examined. The results from this study show that cognitive passwords and authentication by word association are superior to other methods in access control.

Data integrity in computer based information systems is a concern because of the damage that can be done by unauthorized manipulation or modification of data. While a standard exists for data security, there currently is not an acceptable standard for integrity. There is a need for incorporation of a data integrity policy into the standard concerning data security in order to produce a complete protection policy. There are several existing models which address data integrity. The Biba, Goguen and Meseguer, and Clark/Wilson data integrity models each offer a definition of data integrity and introduce their own mechanisms for preserving integrity. Acceptance of one of these models as a standard for data integrity will create a complete protection policy which addresses both security and integrity.

Streszczenie:

In my thesis I shall be investigating two distinct metaplectic extensions of the general linear group. The first of these was discovered by Matsumoto, it's existence intimately connected with the deep properties of the r-th order Hilbert symbol. His construction relies heavily on class field theory and algebraic K-theory. Having constructed his metaplectic group, which is known to be universal, Matsumoto was then able to define the cocycle representing this extension. The second of these metaplectic extensions was found recently by Dr Hill at University College London. In contrast, his construction is very elementary. He was able to prove the existence of a continuous cocycle resulting in the construction of a new non-trivial metaplectic extension. It has already been shown, by Hill, that these two metaplectic extensions are isomorphic if we restrict to the special linear group. However, little is known of this isomorphism. Throughout this thesis we shall investigate these two cocycles, finding explicit formulae in both cases. We shall then show that the isomorphism between the group extensions of Matsumoto and Hill may be defined via the discovery of the coboundary which splits the quotient of the corresponding cocycles. Having found this coboundary we shall then be able to prove that, in specific cases, the two extensions are in fact isomorphic over the full general linear group.

This report is an attempt to find an absorption method that is more suitable for IKEA. Several different methods and standards from around the world are compared to see their pros and cons. The methods are compared both theoretically and practically. The practically comparison is made in a round robin were 14 different fabric is tested in three different methods. Two of the methods in the round robin are compared against each other and the result from a home test to see if the methods can show what the customer experience. The results from the round robin is used to recommend a proper method and requirement level that suit IKEA the best, based on their demands and requirements.

In this thesis I establish a hitherto unseen parallel between John Rawls’ theory of justice and utilitarian accounts with respect to population ethics; I argue that the absurd conclusions which plague utilitarianism also plague Rawls’ theory. These are the repugnant and preposterous conclusions. I then argue that Kant's political philosophy offers the resources to escape these absurd conclusions because of a crucial metaphysical difference between theories governed by outcome-oriented considerations and those governed by freedom-oriented constraints.
