Pino, Luca. "Security aware service composition." Thesis, City University London, 2015. http://openaccess.city.ac.uk/13170/.
Full textAbstract:
Security assurance of Service-Based Systems (SBS) is a necessity and a key challenge in Service Oriented Computing. Several approaches have been introduced in order to take care of the security aspect of SBSs, from the design to the implementation stages. Such solutions, however, require expertise with regards to security languages and technologies or modelling formalisms. Furthermore, existing approaches allow only limited verification of security properties over a service composition, as they focus just on specific properties and require expressing compositions and properties in a model based formalism. In this thesis we present a unified security aware service composition approach capable of validation of arbitrary security properties. This approach allows SBS designers to build secure applications without the need to learn formal models thanks to security descriptors for services, being they self-appointed or certified by an external third-party. More specifically, the framework presented in this thesis allows expressing and propagating security requirements expressed for a security composition to requirements for the single activities of the composition, and checking security requirements over security service descriptors. The approach relies on the new core concept of secure composition patterns, modelling proven implications of security requirements within an orchestration pattern. The framework has been implemented and tested extensively in both a SBS design-time and runtime scenario, based respectively on Eclipse BPEL Designer and the Runtime Service Discovery Tool.

Full textAbstract:
The University of Arizona Composition Program has demonstrated that computers can be integrated successfully into composition instruction. Administrators and instructors are preparing to offer students in second-semester Freshman Composition (English 102) a computer-integrated course of instruction as the equipment and facilities become available. Chapter I relates how current research shows that computers offer support to current theories in composition and that they can be utilized in all the various processes involved with producing university writing. It explores the problems program directors and university administrators face in providing computer technology to undergraduates in writing courses. Chapter II compares the reactions of Southern Arizona Writing Project teacher-participants with freshman students in a pilot section of English 102 at the University of Arizona and with comparable undergraduates at other universities as they learn to use word processors as a tool for writing. Some differences between the older SAWP participants and the undergraduates were observed, especially a greater computer anxiety and a greater of urgency to learn about computers. The SAWP participants had less time to become proficient computer writers than did the freshmen. All these factors probably contributed to their lower success rate as computer writers. Nevertheless, a large majority of all ages of computer writers recognize the benefits of using word processors for writing and even those SAWP participants who made only limited progress expressed a sense of satisfaction at having mastered the machine. Chapter III describes ways that computer writing and strategies of collaborative learning and peer review were adapted to the syllabus of English 102 in a pilot class at the University of Arizona. Students reacted favorably to both computers and to the teaching strategies. However, the vision of total computer integration resulting in a paper-free writing course cannot be achieved without either restructuring the syllabus or acquiring substantially improved computer facilities, especially through networked workstations and computerized classrooms.

McIver, Russell P. "A knowledge-based approach to scientific workflow composition." Thesis, Cardiff University, 2015. http://orca.cf.ac.uk/80633/.
Full textAbstract:
Scientific Workflow Systems have been developed as a means to enable scientists to carry out complex analysis operations on local and remote data sources in order to achieve their research goals. Systems typically provide a large number of components and facilities to enable such analysis to be performed and have matured to a point where they offer many complex capabilities. This complexity makes it difficult for scientists working with these systems to readily achieve their goals. In this thesis we describe the increasing burden of knowledge required of these scientists in order for them to specify the outcomes they wish to achieve within the workflow systems. We consider ways in which the challenges presented by these systems can be reduced, focusing on the following questions: How can metadata describing the resources available assist users in composing workflows? Can automated assistance be provided to guide users through the composition process? Can such an approach be implemented so as to work with the resources provided by existing Scientific Workflow Systems? We have developed a new approach to workflow composition which makes use of a number of features: an ontology for recording metadata relating to workflow components, a set of algorithms for analyzing the state of a workflow composition and providing suggestions for how to progress based on this metadata, an API to enable both the algorithms and metadata to utilise the resources provided by existing Scientific Workflow Systems, and a prototype user interface to demonstrate how our proposed approach to workflow composition can work in practice. We evaluate the system to show the approach is valid and capable of reducing some of the difficulties presented by existing systems, but that limitations exist regarding the complexity of workflows which can be composed, and also regarding the challenge of initially populating the metadata ontology.

Khani, Shahedeh. "Self-reconfigurable, intrusion-tolerant, web-service composition framework." Thesis, City, University of London, 2018. http://openaccess.city.ac.uk/19833/.
Full textAbstract:
The Internet has provided an opportunity for businesses to offer their services as Web Services (WSs). WSs are used to implement Service Ori-ented Architecture (SOA). They enable composition of independent services with complementary functionalities to produce value-added services, which results in less development effort, time consumption and cost, enabling com-panies and organizations to implement their core business only and out-source other service components over the Internet, either pre-selected or on-the-fly. Simple Object Access Protocol (SOAP) based WSs are at risk of se-curity vulnerabilities related to their specific implementation technologies such as Extensible Markup Language (XML) as well as those of their under-lying platforms (e.g., operating systems and frameworks) and their applica-tions (e.g., vulnerability to SQL Injection attacks). Cyber-attacks on WSs may cause unavailability, loss of confidentiality and/or integrity as well as signifi-cant monetary penalties. Security issues become more challenging when Off-The-Shelf Web Services (OTSWSs) are used since they are beyond the con-trol of their clients. The central question underlying this work is: Can a self-reconfigurable Intrusion-Tolerant Web Ser-vice, implemented using N-version programming and diversity formed by composing Off-The-Shelf Web Services that are selected through penetration testing, Principal Component Analysis, and Cluster Analysis process-es mitigate XML-related security vulnerabilities? While aiming to answer the above question, this dissertation presents a novel framework to increase dependability by constructing an Intrusion-Tolerant Web Service (ITWS) in which N-version programming and diversity, formed by composing SOAP-OTSWSs, is used. It describes how penetration testing can be used as a measure of security vulnerabilities of available SOAP-OTSWSs (that offer the required functionality) and the resultant ITWS, how Principal Component Analysis (PCA) and Cluster Analysis (CA) and be utilized to group the SOAP-OTSWSs based on their security vulnerabilities diversity and how a further penetration testing on each group of diverse SOAP-OTSWSs can be used to select the optimal set (most secure among the groups) for construction of ITWS. This dissertation also demonstrates how the dynamic reconfiguration of ITWS, created in Business Process Engineering Language (BPEL), can be enabled using a combination of BPEL constructs and Java as BPEL exten-sion approach and using only Java as BPEL extension approach. The novelty of the work presented in this dissertation is twofold. On the one hand, it is security informed and on the other hand, it demonstrates the use of Java (as BPEL 2.0 extension) to implement self-reconfigurable composite WS. It has the advantage of, at the same time, facilitating a de-pendable service to users and exploiting existing standard technologies. This work also assesses the effectiveness of the proposed solutions through vari-ous case studies and discusses the implications of the proposed framework.

Balestrieri, Florent. "The productivity of polymorphic stream equations and the composition of circular traversals." Thesis, University of Nottingham, 2015. http://eprints.nottingham.ac.uk/29745/.
Full textAbstract:
This thesis has two independent parts concerned with different aspects of laziness in functional programs. The first part is a theoretical study of productivity for very restricted stream programs. In the second part we define a programming abstraction over a recursive pattern for defining circular traversals modularly. Productivity is in general undecidable. By restricting ourselves to mutually recursive polymorphic stream equations having only three basic operations, namely "head", "tail", and "cons", we aim to prove interesting properties about productivity. Still undecidable for this restricted class of programs, productivity of polymorphic stream functions is equivalent to the totality of their indexing function, which characterise their behaviour in terms of operations on indices. We prove that our equations generate all possible polymorphic stream functions, and therefore their indexing functions are all the computable functions, whose totality problem is indeed undecidable. We then further restrict our language by reducing the numbers of equations and parameters, but despite those constraints the equations retain their expressiveness. In the end we establish that even two non-mutually recursive equations on unary stream functions are undecidable with complexity $Π_2^0$. However, the productivity of a single unary equation is decidable. Circular traversals have been used in the eighties as an optimisation to combine multiple traversals in a single traversal. In particular they provide more opportunities for applying deforestation techniques since it is the case that an intermediate datastructure can only be eliminated if it is consumed only once. Another use of circular programs is in the implementation of attribute grammars in lazy functional languages. There is a systematic transformation to define a circular traversal equivalent to multiple traversals. Programming with this technique is not modular since the individual traversals are merged together. Some tools exist to transform programs automatically and attribute grammars have been suggested as a way to describe the circular traversals modularly. Going to the root of the problem, we identify a recursive pattern that allows us to define circular programs modularly in a functional style. We give two successive implementations, the first one is based on algebras and has limited scope: not all circular traversals can be defined this way. We show that the recursive scheme underlying attribute grammars computation rules is essential to combine circular programs. We implement a generic recursive operation on a novel attribute grammar abstraction, using containers as a parametric generic representation of recursive datatypes. The abstraction makes attribute grammars first-class objects. Such a strongly typed implementation is novel and make it possible to implement a high level embedded language for defining attribute grammars, with many interesting new features promoting modularity.

Karakoc, Erman. "Web Service Composition Under Resource Allocation Constraints." Master's thesis, METU, 2007. http://etd.lib.metu.edu.tr/upload/12608309/index.pdf.
Full textAbstract:
Web service composition is an inevitable aspect of web services technology, which solves complex problems by combining available basic services and ordering them to best suit the problem requirements. Automatic composition gives us flexibility of selecting best candidate services at composition time, this would require the user to define the resource allocation constraints for selecting and composing candidate web services. Resource allocation constraints define restrictions on how to allocate resources, and scheduling under resource allocation constraints to provide proper resource allocation to tasks. In this work, web service composition system named as CWSF (Composite Web Service Framework) constructed for users to define a workflow system in which a rich set of constraints can be defined on web services. On the contrary many technologies and studies, CWSF provides a user-friendly environment for modeling web service composition system. The output of the
framework is the scheduling of web service composition in which how and when web services are executed are defined. With this work, a language, CWSL is defined to describe workflow, resource allocation constraints, selection and discovery rules of web services and associated semantic information. An important property of CWSF system is converting web service composition problem into a constraint satisfaction problem to find the best solution that meet the all criteria defined by user. Furthermore, CWSF has ability to display other possible solutions to provides users flexibility. This study also includes semantic matching and mapping facilities for service discovery.

Full textAbstract:
This thesis presents a novel model for service selection and composition in Cloud-based Service-Oriented Architectures (CB-SOA), which is called CloudMTD, using real options, Dependency Structure Matrix (DSM) and propagation-cost metrics. CB-SOA architectures are composed of web services, which are leased or bought off the cloud marketplace. CB-SOA can improve its utility and add value to its composition by substituting its constituent services. The substitution decisions may introduce technical debt, which needs to be managed. The thesis defines the concept of technical debt for CB-SOA and reports on the available technical debt definitions and approaches in the literature. The formulation of service substitution problem and its technical debt valuation is based on options, which exploits Binomial Options Analysis. This thesis looks at different option types under uncertainty. This thesis is concerned with some scenarios that may lead to technical debt, which are related to web service selection and composition that has been driven by either a technical or a business objective. In each scenario, we are interested in three decisions (1) keep, (2) substitute or (3) abandon the current service. Each scenario takes into consideration either one or more QoS attribute dimension (e.g. Availability). We address these scenarios from an option-based perspective. Each scenario is linked to a suitable option type. A specific option type depends on the nature of the application, problem to be investigated, and the decision to be taken. In addition, we use Dependency Structure Matrix (DSM) in order to represent dependencies among web services in CB-SOA. We introduce time and complexity sensitive propagation-cost metrics to DSM to solve the problem. In addition, CloudMTD model informs the time-value of the decisions under uncertainty based on behavioral and structural aspects of CB-SOA.

Full textAbstract:
In this thesis, some novel ideas are presented for solving automated web service composition problem. Some possible real world problems such as partial observability of environment, nondeterministic effects of web services, service execution failures are solved through some mechanisms. In addition to automated web service composition, automated web service invocation task is handled in this thesis by using reflection mechanism. The proposed approach is based on AI planning. Web service composition problem is translated to AI planning problem and a novel AI planner namely &ldquoSimplanner&rdquo
that is designed for working in highly dynamic environments under time constraints is adapted to the proposed system. World altering service calls are done by conforming to the WS-Coordination and WS-Business Activity web service transaction specifications in order to physically repair failure situations and prevent undesired side effects of aborted web service composition efforts.

Hansman-Ferguson, Catherine A. "Writing with computers : a study of adult developmental writers." Virtual Press, 1995. http://liblink.bsu.edu/uhtbin/catkey/941576.
Full textAbstract:
Many adults who enter universities to continue their education are placed in developmental or basic writing classes. With the prevalence of computers on university campuses, some of these writing classes are taught in computerbased classrooms, which may cause adult learners to be apprehensive of both writing and computers. Previous research studies regarding writing and computer apprehension have examined traditional age college students, ignoring how the social context of the computer-based classroom and the computers used as tools for writing may affect adult learners' attitudes toward both writing and computers. The purpose of this descriptive study of adult developmental writers was to examine their perceptions of the effects of computers in a computer-based writing classroom, focusing on how the context of the classroom, including the social situation within the computer-based classroom, influenced their attitudes and apprehension toward both writing and computers.In order to obtain scores that indicated students' apprehension toward writing and computers, the Daly-Miller Writing Apprehension Test and the Loyd and Gressard Computer Attitude Survey were given to adult learners (n=41) at the beginning and the end of the semester to determine changes in students' apprehension. Additional data from interviews, observation reports, and journals of twelve adult learners allowed the researcher to examine students' perceptions of their interactions with other students and between students and their computers, thus promoting an understanding of the context in which learning to write took place.Findings indicated that adult learners' apprehension scores toward writing and computers decreased by the end of the semester in the computer-based classroom. Qualitative data revealed that the computer-based classroom provided a context that enabled students to form supportive peer groups which helped and impacted their writing, allowing them to develop fluid processes for writing with computers.This study has particular relevance for understanding how adults learn to write in various settings. Adult learners are a special population with unique needs. Apprehension toward writing and computers affects adult learners' attitudes toward writing, many times causing them to drop out of educational programs. This study illuminates the problems and feelings adults face as they learn to write using computers.Department of Educational Leadership

Twenty first-year management students were observed as they undertook an Effective Written Communication course (EWC) in a microcomputer lab at McGill University. The study focused on the students' adaptation to the computer during a one-semester course and for a two-year period following the course. Results suggest that although students master the basics of word processors with relative ease, they bring entrenched paper and pen habits to the computer lab; habits that are not easily changed. This study further suggests that because student writers in a first-year composition class are often inexperienced writers and computer users, inferences based upon this group may not apply to other populations.

Kirci, Esra. "Automatic Composition Of Semantic Web Services With The Abductive Event Calculus." Master's thesis, METU, 2008. http://etd.lib.metu.edu.tr/upload/12609949/index.pdf.
Full textAbstract:
In today's world, composite web services are widely used in service oriented computing, web mashups and B2B Applications etc. Most of these services are composed manually. However, the complexity of manually composing web services increase exponentially with the increase in the number of available web services, the need for dynamically created/updated/discovered services and the necessity for higher amount of data bindings and type mappings in longer compositions. Therefore, current highly manual web service composition techniques are far from being the answer to web service composition problem. Automatic web service composition methods are recent research efforts to tackle the issues with manual techniques. Broadly, these methods fall into two groups: (i) workflow based methods and (ii) methods using AI planning. This thesis investigates the application of AI planning techniques to the web service composition problem and in particular, it proposes the use of the abductive event calculus in this domain. Web service compositions are defined as templates using OWL-S ("
OWL for Services"
). These generic composition definitions are converted to Prolog language as axioms for the abductive event calculus planner and solutions found by the planner constitute the specific result plans for the generic composition plan. In this thesis it is shown that abductive planning capabilities of the event calculus can be used to generate the web service composition plans that realize the generic procedure.

Full textAbstract:
Since the personal computing revolution began in the 1980s, digital technologies have become more powerful, affordable, and portable. Those tools have made possible the information age and new ways of communicating. When we connect, we encounter prompts to post, comment, edit, tweet, snap, capture, collaborate, and share. Within an app loaded on a device close at hand are the tools necessary to create and bring together images, videos, sounds, animations, and text. When we mix forms of communication in this way, we create multimodal compositions.
Teachers, students, politicians, corporations, universities, journalists, employers, artists, authors, role models, and friends now communicate with multimodal compositions. The growing significance of multimodal compositions suggests the importance of learning how to consume and create these new media. Many educators consider such skills essential to literacy in the information age. In the context of higher education, rhetoric and composition courses increasingly take on the responsibility of teaching future leaders to make effective and responsible use of multimodal compositions in their communication.
This study considers how college-level composition and rhetoric teachers and their students experience a time of transition between traditional speaking and writing assignments and multimodal composition projects that ask students to integrate different ways of communicating. I use qualitative methods to examine three levels of the composition curriculum: a single assignment, a single course, and a single department. The results point to possible advantages, obstacles, and complications of using multimodality as an approach to college-level literacy teaching and learning.

Full textAbstract:
This study examines the effects of the computer-assisted text analysis program, WRITER'S WORKBENCH, on writing performance, levels of writing apprehension, students' writing processes and attitudes about using the computer and WORKBENCH for writing. A sample of 275 subjects enrolled in freshman composition were divided into an experimental group (N = 200) who used WORKBENCH in a mandatory computer lab component in addition to their composition course and a control group (N = 75) who received only the course, itself. Because random selection of participants was not possible, a Nonequivalent Control Group design was utilized. Holistic scoring of pre and posttest essays revealed a significant improvement in writing among both groups as a result of the treatments, but there was no significant difference in writing gains between the group using WORKBENCH and the group who did not (p = .942) . Similarly, though both groups demonstrated a small decrease in writing apprehension after instruction, there was no significant difference in the degree of decrease between the two groups (p = .201). Also, the data did not support a relationship between writing performance and apprehension. A 40 item questionnaire was given to the experimental group to determine: 1) attitudes about writing with a computer, 2) how students use WORKBENCH, and 3) students' attitudes about WORKBENCH. Some highlights of these findings are that narrow majorities enjoyed and were comfortable using the computer and WORKBENCH, but substantial minorities dissented or were uncertain. While 60% felt happier with their essays after using WORKBENCH and preferred using a computer to write, 89% of students felt word processing represented the greatest advantage and SPELL was the next most popular feature. Personal interviews conducted with 13 of the most and least apprehensive WORKBENCH users revealed that some students ignored the WORKBENCH analyses, and highly apprehensive students experienced more frustration with the computer, employed different writing processes, used WORKBENCH less often and less skillfully, and expressed more dissatisfaction with the computer.

Full textAbstract:
Étude sur la collaboration et la participation active d’un saxophoniste-chercheur avec plusieurs compositeurs dans la création musicale mixte. Les musiques mixtes combinent un performeur jouant d’un instrument acoustique qui interagit avec des outils électroniques et informatiques, se faisant entendre par des hauts-parleurs. Nous comprenons la participation comme des multiples échanges humains intégrant l’écoute, l’instrument acoustique, l’électronique et les dernières technologies numériques dans la musique. Notre méthodologie s’est nourrie des sciences cognitives, de la systémique, de la recherche-action intégrale et systémique, de la cybernétique de second ordre, de l’opérationnel et de l’émergence contextuelle. Notre démarche propose une réflexion autour de quelques bouleversements de l’écoute musicale au XXe siècle et l’étude des musiques mixtes contemporaines sous le biais de l’approche multi-échelle. Nous faisons partie de notre objet d’étude tout en le modifiant dans un processus dynamique. Quelles connaissances musicales émergent de ces échanges de compétences et peuvent en être élargies grâce à cette rétroaction (feedback) multiple, en boucle créative ? Ces questions, avec nos sources de première main et l’inclusion du compositeur en tant qu’interprète ont fait émerger notre concept d’interprétation musicale participative. Nous proposons que l’analyse de nos propres collaborations peut apporter une connaissance originale sur les pièces musicales mixtes en question et développer une sorte de plasticité dans le faire musical. Comme démonstration, des morceaux ont été créées pendant nos recherches et sont analysées sous cette approcheThis research is about the collaboration of a saxophonist-researcher with several composers in electro acoustic music with saxophones. Mixed music combines a performer playing acoustic instruments (traditional or not) interacting with digital and electronics means of all sort of operations, time scales and technical configurations, diffused by loudspeakers. We understand participation in our case as human exchanges in musical digital environments, and as the creation of new links that didn’t exist before. Our research proposes a reflection on listening approaches through the XXst century and studying mixed music through the multi scale approach. The saxophonist gives a contribution, that enhance a creative perspective for each musical piece that influence the composers’ work. Which techniques and which musical knowledge can be exchanged and enlarged thanks to this multiple feedback ? The work on first sources, the competence exchanges between musicians during the many steps of their process of collaborative work construct what we call participatory interpretation in new music. In some aspects we get close to the integral and systemic action-research, since we take part in our study objet, and we modify it in a dynamic process. We propose that the analysis of the musical pieces from our collaborations can bring forth an original knowledge about them and enhance musical creativity. Participatory interpretation optimizes the musical results and explore new mixed “composable” spaces. As a demonstration, some pieces are though analyzed under this participatory perspective. Our research leads to a conclusion towards the idea of plasticity in music making

With the increased presence of computers and communication in every facet of students' lives, students have changed to adapt to the continuous presence of technology in their daily lives. These recent rapid developments have changed the relationship between technology and communication. Indeed, communication and technology have become linked to such a degree that it is difficult to differentiate one from the other, thereby altering our rhetorical situation as instructors. Instructors can no longer deny the presence of technology in the contemporary classroom, much less in the contemporary composition classroom.
This case study serves as a post-modern analysis of the technology based blended classroom. A gap exists between what online learning is (being) today and what it is (becoming) tomorrow. This dissertation explores the gap by examining two rich data sources: online visitor navigational patterns and instructor interviews. The fundamental ideas that this text explores are the following:
- Web server logs and PHP logs can be analyzed to yield relevant information that assists in the design, architecture, and administration of online and blended learning courses.
- Technology in the writing classroom does not necessarily solve traditional problems associated with the composition classroom. Technology is a tool, not a solution.
- Technology has changed the rhetorical situation of the composition classroom. As a result, instructors must adapt to the changed rhetorical environment.
Via this study, readers will hopefully gain a better understanding of the relatively unexplored margins between instruction, composition and technology paradigms. Instructors, trainers, technical writers, pedagogues, industry and academia alike must step forward to research technology-assisted pedagogy so that they can de-privilege the paradigms that position technology itself as a solution, and move forward toward realistic and real-world expectations for instructors in technology mediated learning environments.

Full textAbstract:
Machine learning techniques have been widely used for classification problems in computational biology. They require that the input must be a collection of fixedlength feature vectors. Since proteins are of varying lengths, there is a need for a
means of representing protein sequences by a fixed-number of features. This thesis
introduces three novel methods for this purpose: n-peptide compositions with
reduced alphabets, pairwise similarity scores by maximal unique matches, and
pairwise similarity scores by probabilistic suffix trees.
New sequence representations described in the thesis are applied on three
challenging problems of computational biology: remote homology detection,
subcellular localization prediction, and solvent accessibility prediction, with some
problem-specific modifications. Rigorous experiments are conducted on common
benchmarking datasets, and a comparative analysis is performed between the new
methods and the existing ones for each problem.
On remote homology detection tests, all three methods achieve competitive
accuracies with the state-of-the-art methods, while being much more efficient. A
combination of new representations are used to devise a hybrid system, called
PredLOC, for predicting subcellular localization of proteins and it is tested on two
distinct eukaryotic datasets. To the best of author&rsquos knowledge, the accuracy achieved by PredLOC is the highest one ever reported on those datasets. The maximal unique match method is resulted with only a slight improvement in solvent accessibility predictions.

Full textAbstract:
This study will prove the fact that computers provide unprecedented opportunities to create music. Several distinct levels of computer participation can exist in the creative process. The lowest level, involving record-keeping functions, results in programs that serve as compositional aids. The intermediate level incorporates stochastic (literally "random") processes on a limited basis, and represents the midpoint between computer-assisted and computercomposed works. The highest level focuses on the design of algorithms that result in compositions determined in most of their details by stochastic processes and computer decision making. Although there is no clear dividing line between levels of computer/composer interaction, it is possible to characterize the degree to which the computer has provided outcomes for a given work, from low-level random generation of pitches to high-level Markovian chain distributions.Department of Computer Science

Full textAbstract:
For as long as computers have been around, people have looked for ways to involve them in music. Research in computer music progresses in many varied areas: algorithmic composition, music representation, music synthesis, and performance analysis to name a few. However, computer music research, especially relating to music composition, does very little toward making the computer useful for artists in practical situations. This lack of consideration for the user has led to the containment of computer music, with a few exceptions, to academia. In this thesis, I propose a system that enables a computer to aide users composing music in a specific setting: soundtracks. In the process of composing a soundtrack, a composer is faced with solving non-musical problems that are beyond the experience of composers of standalone music. The system I propose utilizes the processing power of computers to address the non-musical problems thus preventing users from having to deal with them. Therefore, users can focus on the creative aspect of composing soundtrack music.
The guiding principal of the system is to help the composer while not assuming any creative power and while leaving the user in full control of the music. This principal is a major step toward helping users solve problems while not introducing new ones. I present some carefully chosen tasks that a computer can perform with guidance from the user that follow this principal. For example, the system performs calculations to help users compose music that matches the visual presentation and allows users to specify music, using the idea of timed regular expressions, so that a computer can fill arbitrary amounts of time with music in a controlled manner.
A prototype application, called EMuse, was designed and implemented to illustrate the use and benefits of the proposed system. To demonstrate that the system is capable of serving as a tool to create music, two soundtracks were created for two sample animations. It is beyond the scope of the work presented here to evaluate if the system achieves the goal of being a practical tool for composers. However, the innovations herein discussed are analyzed and found to be useful for soundtrack composition and for future user-centered computer-music research.

Full textAbstract:
One of the major challenges in computer science is to put programming on a firmer mathematical basis, in order to improve the correctness of computer programs. Automatic program verification is acknowledged to be a very hard problem, but current work is reaching the point where at least the foundational�· aspects of the problem can be addressed and it is becoming a part of industrial software development. This thesis presents a semantic framework for verifying safety properties of open sequ;ptial programs. The presentation is focused on an Algol-like programming language that embodies many of the core ingredients of imperative and functional languages and incorporates data abstraction in its syntax. Game semantics is used to obtain a compositional, incremental way of generating accurate models of programs. Model-checking is made possible by giving certain kinds of concrete automata-theoretic representations of the model. A data-abstraction refinement procedure is developed for model-checking safety properties of programs with infinite integer types. The procedure starts by model-checking the most abstract version of the program. If no counterexample, or a genuine one, is found, the procedure terminates. Otherwise, it uses a spurious counterexample to refine the abstraction for the next iteration. Abstraction refinement, assume-guarantee reasoning and the L* algorithm for learning regular languages are combined to yield a procedure for compositional verification. Construction of a global model is avoided using assume-guarantee reasoning and the L* algorithm, by learning assumptions for arbitrary subprograms. An implementation based on the FDR model checker for the CSP process algebra demonstrates practicality of the methods.

Full textAbstract:
Cenotaph is a work of fifteen minutes duration for solo tape realized on the Synclavier Digital Music System at the Center for Experimental Music and Intermedia. All of the sound materials in the work consist of resynthesized timbres derived from the analysis of digital recordings of seven different human voices, each speaking the last name of one of the Challenger astronauts. The work's harmonic resources are derived in a unique way involving partitioning of the octave by powers of the Golden Section. The work is in a single movement divided into three sections which function as prologue, action, and epilogue, respectively. This formal structure is reinforced by differentiation of harmonicmaterials and texture. Although Cenotaph cannot be performed "live" and exists only as a recording, a graphic score is included to assist analysis and study.

Full textAbstract:
While it is important for systems intended to enhance musical creativity to define and explore musical ideas conceived by individual users, many limit musical freedom by focusing on maintaining musical structure, thereby impeding the user's freedom to explore his or her individual style. This dissertation presents a comprehensive body of work that introduces a new musical representation that allows users to explore a space of musical rules that are created from their own melodies. This representation, called functional scaffolding for musical composition (FSMC), exploits a simple yet powerful property of multipart compositions: The pattern of notes and rhythms in different instrumental parts of the same song are functionally related. That is, in principle, one part can be expressed as a function of another. Music in FSMC is represented accordingly as a functional relationship between an existing human composition, or scaffold, and an additional generated voice. This relationship is encoded by a type of artificial neural network called a compositional pattern producing network (CPPN). A human user without any musical expertise can then explore how these additional generated voices should relate to the scaffold through an interactive evolutionary process akin to animal breeding. The utility of this insight is validated by two implementations of FSMC called NEAT Drummer and MaestroGenesis, that respectively help users tailor drum patterns and complete multipart arrangements from as little as a single original monophonic track.
The five major contributions of this work address the overarching hypothesis in this dissertation that functional relationships alone, rather than specialized music theory, are sufficient for generating plausible additional voices. First, to validate FSMC and determine whether plausible generated voices result from the human-composed scaffold or intrinsic properties of the CPPN, drum patterns are created with NEAT Drummer to accompany several different polyphonic pieces. Extending the FSMC approach to generate pitched voices, the second contribution reinforces the importance of functional transformations through quality assessments that indicate that some partially FSMC-generated pieces are indistinguishable from those that are fully human. While the third contribution focuses on constructing and exploring a space of plausible voices with MaestroGenesis, the fourth presents results from a two-year study where students discuss their creative experience with the program. Finally, the fifth contribution is a plugin for MaestroGenesis called MaestroGenesis Voice (MG-V) that provides users a more natural way to incorporate MaestroGenesis in their creative endeavors by allowing scaffold creation through the human voice. Together, the chapters in this dissertation constitute a comprehensive approach to assisted music generation, enabling creativity without the need for musical expertise.Ph.D.

Full textAbstract:
This submission explores the development of collaborative computer music creation and the role of the Musical Assistant, or Computer Music Designer, or Live Electronics Designer, or RIM (Réalisateur en informatique musicale) and does so primarily through the consideration of a series of collaborations with composers over the last 18 years. The submission documents and evaluates a number of projects which exemplify my practice within collaborative computer music creation, whether in the form of live electronics, tape-based or fixed media work, as a live electronics performer, or working with composers and others to create original tools and music for artistic creations. A selection of works is presented to exemplify archetypes found within the relational structures of collaborative work. The relatively recent development of this activity as an independent metier is located within its historical context, a context in which my work has played a significant role. The submission evidences the innovative aspects of that work and, more generally, of the role of the Computer Music Designer through consideration of a number of Max patches and program examples especially created for the works under discussion. Finally, the validation of the role of the Computer Music Designer as a new entity within the world of music creation is explored in a range of contexts, demonstrating the ways in which Computer Music Designers not only collaborate in the creation of new work but also generate new resources for computer-based music and new creative paradigms.

Full textAbstract:
Concurrent systems are frequently scrutinised using automated model checking, routinely using Petri nets as a model. While for small system models, it is often sufficient to give the system specification in a monolithic manner, for larger systems this approach is infeasible. Instead, a compositional, or component-wise specification can be used. However, while existing model checking techniques sometimes allow the specification of nets in terms of components, the techniques used for checking properties of the system all consider the composed, global net. In this thesis, we investigate and advocate compositional system specification and an alternative approach to model checking that uses the structural compositional information to its advantage, vastly improving efficiency in many examples. In particular, we examine the categorical structure of component nets and their semantics, illustrating the functoriality of a map between the categories as compositionality. We introduce contextual Petri Nets with Boundaries (PNBs), adding read arcs, which naturally model behaviour that non-destructively reads the token state of a place. Furthermore, we introduce a type-checked specification language that allows us to compositionally construct systems to be modelled using PNBs, whilst ensuring that only correct compositions are expressible. We then discuss and implement compositional statespace generation, which can be used to check reachability. Via optimisations using weak language equivalence and memoisation, we obtain substantial speed ups and demonstrate that our checker outperforms the current state-of-the-art for several examples. A final contribution is the compositional specification of existing benchmark examples, in more natural, component-wise style.

The design and implementation of a computer-assisted tree-ring chronology composition system for dendrochronology is described in this thesis. Methods for tree-ring growth sequence pattern matching, hierarchical composition of master chronologies, and analytical quality control are discussed in detail and systematically implemented in the CROSSDATE program in a highly visual, graphic environment. The objective of this work is to provide dendrochronologists with a robust set of tools for comparing the relative growth patterns of tree-ring samples for purposes of dating the samples and composing new master chronologies from individual tree-ring samples and other master chronologies. This system is complementary to the TREES program, a computer-vision based tree-ring identification and measurement system developed at the University of Arizona.
