Abstract:

The two areas of theory upon which this research was based were 'strategy development process' (SDP) and 'complex adaptive systems' (CAS), as part of complexity theory, focused on human social organisations. The literature reviewed showed that there is a paucity of empirical work and theory in the overlap of the two areas, providing an opportunity for contributions to knowledge in each area of theory, and for practitioners. An inductive approach was adopted for this research, in an effort to discover new insights to the focus area of study. It was undertaken from within an interpretivist paradigm, and based on a novel conceptual framework. The organisationally intimate nature of the research topic, and the researcher's circumstances required a research design that was both in-depth and long term. The result was a single, exploratory, case study, which included use of data from 44 in-depth, semi-structured interviews, from 36 people, involving all the top management team members and significant other staff members; observations, rumour and grapevine (ORG) data; and archive data, over a 5½ year period (2005-2010). Findings confirm the validity of the conceptual framework, and that complex adaptive systems theory has potential to extend strategy development process theory. It has shown how and why the strategy process developed in the case study organisation by providing deeper insights to the behaviour of the people, their backgrounds, and interactions. Broad predictions of the 'latent strategy development' process and some elements of the strategy content are also possible. Based on this research, it is possible to extend the utility of the SDP model by including peoples' behavioural characteristics within the organisation, via complex adaptive systems theory. Further research is recommended to test limits of the application of the conceptual framework and improve its efficacy with more organisations across a variety of sectors.

Abstract:

The ability to drive a car is an important skill for individuals with a spinal cord injury to maintain a high quality of life, particularly their freedom and independence. However, driving with a physical disability often requires the installation of an adaptive driving system to control steering, gas, and braking. The two main types of adaptive driving controls are mechanical and electrical, also known as drive by wire (DBW). DBW controls work by converting electric signals to mechanical actuators. Driving simulators are useful tools for adaptive driving systems because they allow users to test different control devices, to practice driving without the dangers of being on the road, and can be used as a safe way to evaluate disabled drivers. This study focused on the development of a dynamic driving simulator using DBW controls because many studies focus on mechanical controls and not DBW controls and often use static simulators. The simulator was developed using the Computer Assisted Rehabilitation Environment (CAREN) virtual reality system. The CAREN system (Motek Medical, Amsterdam, Netherlands) includes a six degree of freedom (DOF) motion base, an optical motion capture system, a sound system, and a 180-degree projection screen. The two DBW controls, a lever device to control the gas and brake and a small wheel device to control steering, sent an electric signal to a Phidget microcontroller board, which interfaced with the CAREN system. Several different driving scenarios were created and imported into CAREN's D-Flow software. A program was developed in D-Flow to control the scene and motion of the platform appropriately based on the DBW controls via the Phidget. The CAREN system dynamically controlled the motion platform based on the user's input. For example, if the user applied the brake suddenly, the user felt a deceleration from the motion platform moving backwards. Human testing was performed and through the use of a survey, feedback about the system was obtained. Changes were made to the simulator using the feedback obtained and further testing showed that those changes improved the simulator. The driving simulator showed the capability to provide dynamic feedback and, therefore, may be more realistic and beneficial than current static adaptive driving simulators. The dynamic adaptive driving simulator developed may improve driving training and performance of persons with spinal cord injuries. Future work will include more human testing. The dynamic feedback provided through the system's moving platform and virtual camera movement will be optimized in order to perform similarly to a real car. Testing will also be completed with and without the dynamics from the moving platform to see how this type of feedback affects the user's driving ability in the virtual environment.

Abstract:

Although no one program exists for leadership development, there is an understanding among practitioners and researchers that leader and leadership development occur in many venues, with one of those venues being an academic classroom where experience and theory are juxtaposed. One such program is the Eisenhower Leadership Development Program. In an effort to strengthen the academic discipline of leadership and to garner further respect for leadership development programs such as ELDP, leadership development programs must be assessed and evaluated in order to ensure that the objective of the program is being met. Brungardt and Crawford noted that, "assessment and evaluation of leadership programs help ground programs in the needs of students while working within the constraints of academe" (1996, p. 37). The purpose of this study was twofold. First, this study sought to ensure that the Eisenhower Leadership Development Program was producing the outcomes the program was designed to produce. Second, this study sought to demonstrate the worth of ELDP to past, current, and future stakeholders. Former ELDP students were surveyed regarding the perceptions of their learning outcomes based on four practical skills (problem defintion, discovery of research alternatives, delegation/teamwork, and achievable challenge) and four complimentary adaptive skills (focusing on an issue, direct attention to detail, management of time and resources, and persistence). This study found that students did perceive to have gained leadership skills in each of the practical and adaptive skill constructs. The comparison between students' perceptions of each skill before participating in ELDP and after participating in ELDP was positively correlated and statistically significant in every construct. In short, the relationship between the practical and adaptive skills taught in ELDP and the learning outcomes is not serendipitous. The findings show that ELDP is improving the development of students in terms of them becoming leaders and in terms of the greater concept of leadership as related to the four practical and adaptive skills emphasized by ELDP. Further research related to the interdisciplinary design through which the practical and adaptive skills are taught is recommended.

Abstract:

This dissertation presents a new framework for the development and analysis of blind adaptive algorithms. An adaptive algorithm is said to be 'blind' if it does not require a known training sequence. The main focus is on application of these algorithms to adaptive antenna arrays in mobile radio communications. Adaptive antenna arrays can reduce the effects of cochannel interference, multipath fading, and background noise as compared to more conventional antenna systems. For these reasons, the use of adaptive antennas in wireless communication has received a great deal of attention in the literature. There are several reasons why the study of blind adaptive algorithms is important. First, it is common practice to switch to a blind mode once the training sequence has been processed in order to track a changing environment. Furthermore, the use of a blind algorithm can completely eliminate the need for a training sequence. This is desirable since the use of a training sequence reduces the number of bits available for transmitting information. The analysis framework introduced here is shown to include the well-known Constant Modulus Algorithm (CMA) and decision directed algorithm (DDA). New results on the behavior of the CMA and DDA are presented here, including analytic results on the convergence rate. Previous results have relied on Monte Carlo simulation. This framework is also used to propose a new class of blind adaptive algorithms that offer the potential for improved convergence rate.

Abstract:

This study documented the psychometric development of the Adaptive Leadership Competency Profile (ALCP). The ALCP was derived from a qualitative database from the National Science Foundation project (NSF 9422368) and the academic body of literature. Test items were operationalized, and subject matter experts validated 11 macro-leadership competencies and 65 items. Rasch rating scale measurement models were applied to answer the following questions: (a) How well do the respective items of the ALCP fit the Rasch rating scale measurement model for the 11 scales of the ACLP? (b) How well do the person's abilities fit the Rasch rating scale measurement model, using the 11 scales of the ALCP? (c) What are the item separation and reliability coefficients for the 11 ALCP scales? (d) What are the person separation and reliability coefficients for the 11 ALCP scales? This study also sought to discern whether the ALCP could predict leader effectiveness as measured by the likelihood ratio index and frequency of correct predictions indices. The WINSTEPS and LIMDEP programs were used to obtain Rasch calibrations and probit estimates, respectively. The ALCP profiles the frequency and intensity of leadership behavior. Composite measures were calculated and used to predict leadership effectiveness. Results from this study validated 10 competencies and 55 items.

Abstract:

Over the last 70 years, teams have become the ubiquitous unit of work in our organizations. The software industry heavily utilizes the Scrum methodology to develop software. Scrum is a team-based methodology that requires the constant formation and development of team capabilities. Researchers and practitioners dealing with work team dynamics have relied on the popular team developmental stages of forming, storming, norming, and performing, defined by Dr. Bruce Tuckman in 1965. However, this framework was conceived primarily from articles dealing with therapy groups and not modern teams. This study expands the body of research in work team stage development applied to Scrum, a methodology that itself has no social science foundation and minimal theoretical coverage.

A combined case study and grounded theory method is used to leverage the strengths of both to investigate the developmental stage of 5 Scrum teams at a high-tech company. A questionnaire along with team interviews were utilized to gather data on how teams relate to developmental factors found in the literature. Descriptive analytics were leveraged to uncover the questionnaire findings, and grounded theory analysis was applied to code interview answers into usable concepts, categories, and themes. Themes were further explored concerning their causal relationships.

The study proposed and validated 12 theoretical factors that contribute to the stage development of Scrum teams across 4 distinct stages. These factors interconnect and form 4 quadrants with unique dynamics associated with a team’s mission, structure, execution, and teaming. Furthermore, higher stage teams proved to be self-managed and adaptable and able to handle higher task complexity. Leaders were observed shifting roles as teams evolved through stages. This latter finding is consistent with the theoretical model of Kozlowski, Watola, Jensen, Kim, and Botero. The research also identified common challenges that teams encounter in their development.

The findings from this study can help organizations who practice Scrum become more intentional about the development of their teams toward adaptability. A concerted effort by software organizations to optimize the evolution of teams across the factors found in the study could yield significant benefits, particularly for missions dealing with high complexity and innovation needs.

Abstract:

L'imagerie mono-pixel est un concept récent qui permet l'obtention d'images à un coût relativement faible par une compression des données durant l'acquisition. L'architecture d'une caméra mono-pixel comprend seulement deux éléments, un modulateur spatial de la lumière et un détecteur ponctuel. L'idée est de mesurer, au niveau du détecteur, la projection de la scène observée -l'image- avec un certain motif. Le post-traitement d'une séquence de mesures obtenues avec différents motifs permet de restaurer l'image de la scène. L'imagerie mono-pixel possède plusieurs avantages qui sont d'un intérêt pour différentes applications, en particulier dans le domaine biomédical. Par exemple, une caméra mono-pixel résolue en temps bas coût est bénéfique pour l'imagerie de temps de vie de fluorescence. Un tel système peut également être couplé à un spectromètre afin de compléter le temps de vie avec une information spectrale. Cependant, la limite principale de l'imagerie mono-pixel est la vitesse d'acquisition et/ou de l'étape de restauration d'image qui est, à ce jour, non compatible avec des applications temps réel. Le but de cette thèse est de développer des méthodes rapides d'acquisition et de restauration des images à visée d'applications biomédicales. Tout d'abord, une stratégie d'acquisition basée sur les algorithmes de compression dans le domaine ondelettes est proposée. Celle-ci accélère le temps de restauration de l'image par rapport aux schémas d'acquisition classiques basés sur l'acquisition comprimée. Dans un second temps, une nouvelle méthode pour lever une contrainte expérimentale de positivité sur les motifs est détaillée. Comparée aux approches classiques, cette méthode basée sur une factorisation en matrices non-négatives permet de diviser par deux le nombre de motifs envoyés au modulateur spatial de la lumière, entrainant ainsi une division par deux du temps d'acquisition total. Enfin, l'applicabilité de ces techniques est démontrée pour de l'imagerie multispectrale et/ou résolue en temps, modalités courantes dans le domaine biomédical
Single-pixel imaging is a recent paradigm that allows the acquisition of images at a reasonably low cost by exploiting hardware compression of the data. The architecture of a single-pixel camera consists of only two elements, a spatial light modulator and a single point detector. The key idea is to measure, at the detector, the projection (i.e., inner product) of the scene under view -the image- with some patterns. The post-processing of a measurements sequence obtained with different patterns permits to restore the desired image. Single-pixel imaging has several advantages, which are of interest for different applications, especially in the biomedical field. In particular, a time-resolved single-pixel imaging system benefits to fluorescence lifetime sensing. Such a setup can be coupled to a spectrometer to supplement lifetime with spectral information. However, the main limitation of single-pixel imaging is the speed of the acquisition and/or image restoration that is, as of today, not compatible with real-time applications. This thesis investigates fast acquisition/restoration schemes for single-pixel camera targeting biomedical applications. First, a new acquisition strategy based on wavelet compression algorithms is reported. It is shown that it can significantly accelerate image recovery compared to conventional schemes belonging to the compressive sensing framework. Second, a novel technique is proposed to alleviate an experimental positivity constraint of the modulation patterns. With respect to the classical approaches, the proposed non-negative matrix factorization based technique permits to divide by two the number of patterns sent to the spatial light modulator, hence dividing the overall acquisition time by two. Finally, the applicability of these techniques is demonstrated for multispectral and/or time-resolved imaging, which are common modalities in biomedical imaging

Abstract:

Purpose: Working from lifespan development theory and the theory of Selective Optimization with Compensation (SOC), I provide theoretical analyses to inform and direct research on Taijiquan where research questions involve issues of adaptive development (optimization of gains, maintenance of function, and prevention of lost resources). I also used these frameworks to construct a biopsychosocial mind-body practices model that seeks to explain and predict the role of key aspects (curriculum, practice, context) in Taiji-related development. The above frameworks are further substantiated through a comparative analysis of health status between Taijiquan practitioners (N =120; age range = 24-83, M = 54.77) and a nationally representative sample (N = 414,629; age range = 18-99, M = 54.86) collected by the Centers for Disease Control and Prevention (CDC). The modelâ s predictive potential is explored through an analysis of health status within a subset of experienced Taiji practitioners (N = 94; age range = 24-83, M = 55.82). Design: Theoretical and cross-sectional; between- and within-group comparisons. Methods: Responses from a convenience sample of Taiji practitioners were collected using an online survey. The instrument was designed to collect data on health-related quality of life (HRQoL), lifestyle variables, and Taiji practice regimens. Data from Taiji practitioners were merged with the CDCâ s 2008 Behavioral Risk Factor Surveillance System (BRFSS) dataset, forming three groups: no exercise, some exercise, and Taiji exercise. Health status was regressed on exercise group while controlling for age, income, and education, as well as the interaction between age and exercise group. Further analyses were also conducted on a subset of the Taiji data (N=94). These analyses examined the relationships among self-reported health, practice regimens, and diet while controlling for age and experience. Results: In the first set of analyses (see paper one), I controlled for the effects of age, income, education, and the differential effects of age on exercise group, while determining associations between health and group membership. A significant interaction effect (p < 0.001) occurred between age and exercise group membership. This interaction showed little difference between exercise groups in the young adult age range, but among older adults, Taijiquan practitioners displayed the best HRQoL. In the second set of analyses (see paper 2), I found significant interaction effects between (a) curricular complexity and out-of-class practice (p < 0.05) and (b) curricular complexity and diet (p < 0.05). Conclusions: The extraordinary health status trajectory among Taiji practitioners may be attributable to several conditions including: (a) the implied presence of SOC-related strategies, (b) the general benefits of psychophysical expertise, and (c) concomitant structure between Taiji-related goals and health behaviors that contributes to optimal aging. Specifically, intervention designers, Taiji teachers, and practitioners should consider the potential benefits of well rounded Taiji curricula, regular out-of-class practice, and healthy diet for optimizing health-related gains and minimizing losses typically associated with aging.

Psychology
Ph.D.
Sensitive and responsive parenting promotes adaptive outcomes for children. Within the domain of language development, responsiveness has been examined through the effects of temporal and semantic contingency on children’s vocabularies. The term adaptive contingency can be used to characterize the process whereby dyads co-construct common ground, establishing a co-dependence of both timing and meaningfulness. This dissertation examined the role of adaptive contingency in early verb learning by examining the learning consequences when timing is manipulated but meaning is held constant (Study 1) and when meaningfulness is manipulated but timing is held constant (Study 2). In a previous study, toddlers learned novel action words when teaching was uninterrupted, but failed to do so when caregivers were interrupted while teaching by a cell phone call from the experimenter (Reed, Hirsh-Pasek, & Golinkoff, in preparation). Study 1 explored how the timing of interruptions differentially affects word learning. Experimenters blind to study hypotheses taught two-year old toddlers novel words, and learning was assessed via the Intermodal Preferential Looking Paradigm (IPLP). During the teaching period, experimenters responded to text messages, momentarily disrupting the teaching. The timing of these interruptions occurred (1) in the middle of an utterance, such that the label and demonstration of its action referent were decoupled, (2) before the “label + action referent” event occurred, or (3) after (the control condition). At test, only children in the after condition learned the novel words. Study 2 examined whether word learning would be disrupted when teaching interactions were interrupted by an event that breaks the shared focus (e.g., a cell phone call) but not when the interruption shifts the shared context (e.g., when a lighted display suddenly shines). Novel words were learned in one of three experimental conditions (light display to shift attention, cell phone call to break attention, no interruption control), and learning was again assessed via the IPLP. Only toddlers in the shift condition learned the novel words. This dissertation contributes to the growing recognition that the quality of interactions with caregivers affects children’s language trajectories (e.g., rich and diverse vocabulary, Rowe, 2012; fluent and connected bouts of sustained joint attention, Hirsh-Pasek et al., in press). Utilizing ecologically valid interruptions, the two studies together illuminate how the social context can support or hinder early verb learning.

Full text

Abstract:

Random testing is a standard software testing method. It is a popular method for reli-ability assessment, but its use for debug testing has been opposed by some authorities. Random testing does not use any information to guide test case selection, and so, it is argued, testing is less likely to be effective than other methods. Based on the observation that failures often cluster in contiguous regions, Adaptive Random Testing (ART) is a more effective random testing method. While retaining random selection of test cases, selection is guided by the idea that tests should be widely spread throughout the input domain. A simple way to implement this concept, FSCS-ART, involves randomly generating a number of candidates, and choosing the candidate most widely spread from any already-executed test. This method has already shown to be up to 50% more effective than random testing. This thesis examines a number of theoretical and practical issues related to ART. Firstly, an theoretical examination of the scope of adaptive methods to improve testing effectiveness is conducted. Our results show that the maximum improvement in failure detection effectiveness possible is only 50% - so ART performs close to this limit on many occasions. Secondly, the statistical validity of the previous empirical results is examined. A mathematical analysis of the sampling distribution of the various failure-detection effectiveness methods shows that the measure preferred in previous studies has a slightly unusual distribution known as the geometric distribution, and that that it and other measures are likely to show high variance, requiring very large sample sizes for accurate comparisons. A potential limitation of current ART methods is the relatively high selection overhead. A number of methods to obtain lower overheads are proposed and evaluated, involving a less-strict randomness or wide-spreading criterion. Two methods use dynamic, as-needed partitioning to divide the input domain, spreading test cases throughout the partitions as required. Another involves using a class of numeric sequences called quasi-random sequences. Finally, a more efficient implementation of the existing FSCS-ART method is proposed using the mathematical structure known as the Voronoi diagram. Finally, the use of ART on programs whose input is non-numeric is examined. While existing techniques can be used to generate random non-numeric candidates, a criterion for 'wide spread' is required to perform ART effectively. It is proposed to use the notion of category-partition as such a criterion.

Full text

Abstract:

Reconfiguration is needed to meet the fight-through and survivability requirements of a shipboard power system. Reconfiguration involves the re-arrangement of power system topology through the opening and switching of breakers, and adjusting of total generators and load values. When the power system is reconfigured, the protection system needs to be attuned to the new power system state. This thesis focuses on developing an adaptive protection scheme for shipboard power systems that will automatically update relay settings after changes in power system topology and operational state. The developed adaptive protection scheme employs four main algorithms to achieve its goal. A topology-recognition algorithm uses the statuses (open/close) of breakers to determine the topological-configuration of the system. A power-flow and a fault-analysis algorithm are used to determine the system?s normal and fault currents, respectively. A protection-setting algorithm is used to determine and set the operating parameters of all the relays in the system. The scheme was implemented in MATLAB m-files and tested on various configurations of a notional shipboard power system. The tests results were verified in CAPE.

Full text

Abstract:

The thesis addresses the question of how to establish an appropriate methodology for monitoring sustainable tourism development (STD) in Samoa, an independent small island state in the South Pacific. The theoretical starting point and common thread throughout this study is that sustainable development can and must form the paramount context for STD. The author adopts an interdisciplinary approach, drawing on innovative research in the field of ecology and ecosystem management in order to gain understanding of new and emerging interpretations of sustainability and their implications for STD. Three guiding principles are identified and consequently form the conceptual foundation for the work. That understanding and implementing STD requires: i) a comprehensive systemic approach; ii) a stakeholder-driven focus; and iii) the adaptive capacity to accommodate the non-linear behaviour of complex systems. These principles are tested in the context of the development of a place-based STD monitoring programme in Samoa. In collaboration with the Samoa Visitors Bureau (SVB) and a multidisciplinary stakeholder committee, a set of STD objectives for Samoa were formulated, 20 indicators were identified to monitor progress towards their achievement, and a monitoring programme was established to utilise the results. The objectives and corresponding indicators are broad in their coverage of tourism and sustainable development issues, have stakeholder resonance, and are feasible considering the technical and human capacity currently available in SVB. The monitoring programme also has the flexibility to adapt to change as it inevitably occurs. The work undertaken in Samoa demonstrates that as well as generating timely information on the current state of STD, if a stakeholder approach is adopted, monitoring can also provide the opportunity for considerable social learning, and help bridge the gap between indicator development and indicator use, ensuring indicator results are actually used to change the way tourism is planned, developed and managed.

Abstract:

This exploratory study uses the convergent design of mixed methods to integrate adaptive expertise theory to study how individual student participant from graphic design or non-graphic-design majors to solve a novel ideation problem in graphic design. Adaptive expertise includes six dimensions: metacognition, flexibility, dynamic knowledge, ability to welcome challenges, efficiency and deep understanding of the domain knowledge, and multiple perspectives. Those are desired qualities for a learner to stand out in the global market that are constantly changing with complex challenges. Thirty undergraduate students participated in this study. This study aims to answer four questions: types of graphic design tool and strategies selection and reasoning, similarities and differences among four participant groups, influences of participants’ performance from the prior-experiences, and other potential preconceptions and situations to their reasoning. Four results are identified. Frist, 11 rationales contributed to participants to make their tool usage decision and strategies. Second, participant with more varieties of prior experiences in graphic design would potentially have significantly higher confidence level in their adaptive expertise. Third, participants who performed better in this study, obtained more thorough reflection in design thinking. This result shows that this task requires domain-dependent expertise. Forth, participants’ performance found affected by several non-cognitive preconceptions such as uncertain challenges, adapting in the new work space, and stress management. Future studies need to increase the number of participants to potentially increase statistical significance of the results, and to identify the relationship among factors that affect participants’ performance and exhibition of adaptive expertise. Implications of this study suggests the need to expose learners to diverse types of graphic design experiences and novel tasks/contexts.

Abstract:

In recent years, there has been an increasing interest in extracting valuable information from large amounts of data. This information can be useful for making predictions about the future or inferring unknown values. There exists a multitude of predictive models for the most common tasks of classification and regression. However, researchers often assume that data is clean and far too little attention has been paid to data pre-processing. Despite the fact that there are a number of methods for accomplishing individual pre-processing tasks (e.g. outlier detection or feature selection), the effort of performing comprehensive data preparation and cleaning can take between 60% and 80% of the whole data mining process time. One of the goals of this research is to speed up this process and make it more efficient. To this end, an approach for automating the selection and optimisation of multiple preprocessing methods and predictors has been proposed. The combination of multiple data mining methods forming a workflow is known as Multi-Component Predictive System (MCPS). There are multiple software platforms like Weka and RapidMiner to create and run MCPSs including a large variety of pre-processing methods and predictors. There is, however, no common mathematical representation of MCPSs. An objective of this thesis is to establish a common representation framework of MCPSs. This will allow validating workflows before beginning the implementation phase with any particular platform. The validation of workflows becomes even more relevant when considering the automatic generation of MCPSs. In order to automate the composition and optimisation of MCPSs, a search space is defined consisting of a number of preprocessing methods, predictive models and their hyperparameters. Then, the space is explored using a Bayesian optimisation strategy within a given time or computational budget. As a result, a parametrised sequence of methods is returned which after training form a complete predictive system. The whole process is data-driven and does not require human intervention once it has been started. The generated predictive system can then be used to make predictions in an online scenario. However, it is possible that the nature of the input data changes over time. As a result, predictive models may need to be updated to capture the new characteristics of the data in order to reduce the loss of predictive performance. Similarly, preprocessing methods may have to be adapted as well. A novel hybrid strategy combining Bayesian optimisation and common adaptive techniques is proposed to automatically adapt MCPSs. This approach performs a global adaptation of the MCPS. However, in some situations, it could be costly to update the whole predictive system when maybe just a little adjustment is needed. The consequences of adapting a single component can, however, be significant. This thesis also analyses the impact of adapting individual components in an MCPS and proposes an approach to propagate changes through the system. This thesis was initiated due to a joint research project with a chemical production company, which has provided several datasets with common raw data issues in the process industry. The final part of this thesis evaluates the feasibility of applying such automatic techniques for building and maintaining predictive models for real chemical production processes.

Abstract:

The integration of shape memory alloys (SMAs) into textile-reinforced composites produces a class of smart materials whose shape can be actively influenced. In this paper, Ni-Ti SMA wires are inserted during the weaving of a glass fiber reinforcement textile. This ‘‘active’’ reinforcement is then combined with an elastomeric matrix to produce a highly flexible composite sheet, which maintains high rigidity in the longitudinal direction. By activating the SMAs, high deflection ratios of up to 35% (relative to the component’s length) are achieved. To adjust the composite’s deflection to defined values, a closed-loop control is set up to adjust the current flow through the SMA wires. A control algorithm is designed and evaluated for several test cases. The high deformability and the controllable behavior show the high potential of these materials for applications such as aerodynamic flow control, automation and architecture.

Abstract:

Organizations have become the backbone of the society. Humans live around all kinds of organizations, such as neighborhood communities, businesses, schools, unions, political, sports, and religious organizations, etc. These organizations have a set of members, each playing a specific role, which determines their duties and functionalities within the organization. One of these functionalities is to offer a range of services to members of the organization and external people. These members must follow a set of norms to ensure the proper functioning of the organization and should pursue the global goals of the organization. A feature that is repeated in organizations is that they are not static but dynamic, resulting in changes in both its structure and the way in which they behave. In an organization, any of its elements is prone to change due to situations that occur in the organization itself or its environment. Researchers in the field of social sciences and organizations have studied such situations, the reasons why they appear and solutions and actions to be taken to ensure that this situation does not damage the organization or to take advantage of the situation. These situations are known as ‘Forces that drive organizational change’. Human organizations are the main source of inspiration for the Multi-Agent Systems (MAS) based on organizations. These systems are computational abstractions that are populated by agents instead of people, but take into account organizational elements such as roles, services, goals, norms, etc. However, the proposals that have been presented up to now to define this type of MAS are focused mostly on static systems, without changes in its structure. Moreover, in the few proposals that take into account organizational changes, they just state that changes occur, but without specifying the reason for change. Thus, the concept of ‘forces that drive organizational change’ (and their features) is not considered. Therefore, the objective of this PhD thesis is to translate the knowledge of the forces that drive organizational change available in human organizations to MASbased organizations. These forces will be formally expressed with the factors that help to detect them. The solutions to be taken when a force is detected will also be presented. To correctly perform this task, a formalization for virtual organizations is designed, named Virtual Organization Formalization (VOF). Moreover, the Artifacts for Organizational Mechanisms are proposed, which are a tool to help in the representation of organizational knowledge and in the modeling of the environment of the organization. This tool is based on the Agents & Artifacts (A&A) framework.

Abstract:

Sound pressure equalization of audio signals using digital signal processors has been a subject of ongoing study for many years. The traditional approach is to equalize sound at a point in a listening environment, but because of its specific dependence on the room frequency response between a source and receiver position, this equalization generally causes the spectral response to worsen significantly at other locations in the room. This work presents both a time-invariant and a time-varying implementation of an adaptive acoustic energy density equalization filter for a one-dimensional sound field. Energy density equalization addresses the aforementioned challenge and others that relate to sound equalization. The theory and real-time implementation of time-invariant sound pressure and energy density equalizers designed using the least-squares method are presented, and their performances are compared. An implementation of a time-varying energy density equalizer is also presented. Time-invariant equalization results based on real-time measurements in a plane-wave tube are presented. A sound pressure equalizer results in a nearly flat spectral magnitude at the point of equalization. However, it causes the frequencies corresponding to spatial nulls at that point to be undesirably boosted elsewhere in the sound field, where those nulls do not exist at the same frequencies. An energy density equalization filter identifies and compensates for all resonances and other global spectral effects of the tube and loudspeaker. It does not attempt to equalize the spatially varying frequency nulls caused by local pressure nodes at the point of equalization. An implementation of a time-varying energy density equalizer is also presented. This method uses the filtered-x filter update to adjust the filter coefficients in real-time to adapt to changes in the sound field. Convergence of the filter over time is demonstrated as the closed end of the tube is opened, then closed once again. Thus, the research results demonstrate that an acoustic energy density filter can be used to time-adaptively equalize global spectral anomalies of a loudspeaker and a one-dimensional sound field.

Abstract:

The usage of Unmanned Aerial Systems (UASs), such as quadcopters and hexacopters, has steadily increased over the past few years in both recreational and commercial use. This increased availability to purchase such systems has also given rise to many safety and security concerns. A common concern is that the misuse of a UAS can cause damage to airplanes and helicopters in and around airports. Another growing concern is the use of UASs for terrorist intentions such as using the UAS as a remote controlled bomb. There is clearly a need to be able to detect the presence of unwanted UASs in restricted areas. This thesis work presents the beginning work towards a method to detect the presence of these UASs using the blade pass frequency (BPF) of the motors and rotors of a home made quadcopter. A low cost uniform linear microphone array is first used to perform a simple delay-and-sum beamformer to spatially filter out noise sources. The beamformer output is then divided into sub-bands using three bandpass filters centered on the expected location of the fundamental BPF and its 2nd and 3rd harmonics. For each sub-band, an adaptive filter called an adaptive line enhancer is used to extract and enhance the narrowband signals. The response of the adaptive filters are then used to detect the quadcopter by looking for the presence of the 2nd and 3rd harmonics of the fundamental BPF. Static tests of the quadcopter out in a field showed promising results for this method with the ability to detect up to the 3rd harmonic 90ft away and the 2nd harmonic 130 ft away.

Abstract:

The adaptive landscape heuristic can be used to answer the question "how predictable is evolution?" because its topology will impact the repeatability of evolution. In my Masters research I addressed this question in two ways: (1) I reviewed empirical adaptive landscape studies in the fields of directed protein evolution and microbial experimental evolution and (2) I performed a selection experiment to characterize adaptive landscape topology by measuring variance in fitness and metabolic phenotype within and among genetically distinct Pseudomonas fluorescens strains in two environments. Empirical studies have found that protein level landscapes are generally smooth, however, population level landscapes are rugged even in simple environments. Experimentally I found that the pattern of variance in fitness and metabolic phenotype was unique to the selection environment. The response to selection was highly repeatable at the level of fitness, but the underlying genetic routes taken were different for each environment and more variable in xylose than in glucose, suggesting a more rugged underlying landscape. More generally, my research suggests that making statements about the predictability of adaptive evolution at the population level may be challenging and wi11likely depend on the specifics of the environment in which selection occurs.

Abstract:

The ultimate goals of adaptive serious educational games (adaptive SEG) are to promote effective learning and maximising enjoyment for players. Firstly, we develop the SEG by combining knowledge space (learning materials) and game content space to be used to convey learning materials. We propose a novel approach that serves toward minimising experts' involvement in mapping learning materials to game content space. We categorise both content spaces using known procedures and apply BIRCH clustering algorithm to categorise the similarity of the game content. Then, we map both content spaces based on the statistical properties and/or by the knowledge learning handout. Secondly, we construct a predictive model by learning data sets constructed through a survey on public testers who labelled their in-game data with their reported experiences. A Random Forest algorithm non-intrusively predicts experiences via the game data. Lastly, it is not feasible to manually select or adapt the content from both spaces because of the immense amount of options available. Therefore, we apply reinforcement learning technique to generate a series of learning goals that promote an efficient learning for the player. Subsequently, a combination of conditional branching and agglomerative hierarchical clustering select the most appropriate game content for each selected education material. For a proof-of-concept, we apply the proposed approach to producing the SEG, named Chem Dungeon, as a case study to demonstrate the effectiveness of our proposed methods.

Abstract:

This thesis advances a conceptual model of adaptive impact monitoring that is designed to overcome many of the criticisms plaguing conventional monitoring strategies. The potential for applying the adaptive model is demonstrated for the Peace River Site C dam proposed for northeastern British Columbia. Environmental impact assessment (EIA) has progressed considerably from its early biophysical orientation to a more comprehensive, interdisciplinary process concerned with the breadth of environmental and socio-economic impacts of development. Impact monitoring, an essential EIA component, has also progressed but in a less innovative fashion. Consequently, conventional monitoring strategies often contain significant deficiencies including insufficient use of past experience, poor monitoring design, and failure to recognize the learning opportunity offered by each project. Adaptive impact monitoring offers significant advantages over traditional strategies. An adaptive strategy is based on a series of impact hypotheses established and tested by an interdisciplinary design team and has two fundamental stages: design and evaluation. A review of the potential environmental impacts of hydroelectric production indicates that the reservoir impact paradigm is beginning to provide a comprehensive basis for assessing development effects. Although the Site C EIA adequately reflects the reservoir impact paradigm, it has three significant weaknesses. First, the potential impacts on downstream ecology and distant downstream users are ill-considered. Second, the potential for increased Site C fisheries parasitism is neglected. Finally, estimates of maximum sustainable yield for the Site C reservoir and Peace River fisheries are unreliable. While opportunities for future impact monitoring were recognized through the Site C panel hearings, they lacked flexibility. The potential impacts on downstream water temperature and fisheries resources are used to illustrate the applicability of the adaptive strategy and the advantages derived from collecting only relevant, statistically credible data to permit testing impact hypotheses in a cost-effective manner. On the basis of these findings, six major policy recommendations are provided for improving the effectiveness of impact monitoring and management for future resource developments.

Abstract:

Existing optical microscopy techniques compromise between resolution, photodamage, speed of acquisition and imaging in to deep samples. This often confines a technique to a certain biological system or process. We present a versatile imaging system which can switch between imaging modalities with sub millisecond transition times to adapt to the needs of a wide range of sample types. The imaging modalities provide the minimally invasive but low-resolution epi-fluorescence though increasing invasive but higher resolution confocal and structured illumination until the highest resolution is achieved through the most intrusive, localisation microscopy. The ability of the system to overcome the limitations of conventional single mode microscopy is demonstrated by several biological investigations. The ideas presented in this work allow researchers to move away from the model of a single imaging modality to study a specific process and instead follow those processes using the most suitable method available during the lifetime of the investigation.

Abstract:

External fixation is a surgical treatment primarily utilised for long bone fracture stabilisation. External fixation, through either pin or wire insertion, is done by constraining bone fragments and providing support to the injury via external scaffolding built across the fracture., but it can also be used to solve both traumatic and congenital bony deformities. Certain devices, particularly the Ilizarov Ring Fixator, can employ external bone fixation to create a biomechanical environment to gradually correct deformities (comprised of: translation, rotation and angulation). A typical application for deformity correction is the fixation of lower leg fractures, particularly tibial fractures, which have been recognised as the most common incident in long bone fractures. External ring fixators have become more developed; manufactured from sophisticated materials; or designed to incorporate computational support, to achieve accurate correction, however these factors have created limitations regarding their accessibility, complexity and ease in application. In addition, standard systems are not as versatile or correctively exact as required to prove their cost of use, creating reluctance as well as added bias towards the more developed devices. Threedimensional and multi-planar deformity correction has become major factors for current devices, yet the feasibility to use such expensive and complex devices may not be beneficial for all parties. External Fixation Systems are considered operationally expensive. Standard systems still utilise expensive and cumbersome setups, while developed devices require computational consultation and extensive training. With such complex procedural actions required to facilitate multi-planar correction, most devices utilise computational support, which in turn minimizes the clinician’s control. The current study aims to design a light-weight Adaptive External Bone Fracture Fixation System that can offer definite treatment and full clinical control over the injury. The system is to be able to stabilise and offer correction of planar bony deformities via controlled shape change. The functional verification of the device was limited to (according to the scope) stress testing. The proposed device consists of hinge systems capable of allowing for full assembly expansion to permit quick installation for various injury structures or states. In addition, the design possesses longitudinal elements that can offer both rapid and finite lengthening (with lock-and-switch) to offer both rapid and gradual system shape change, improving the control over the injury fixation. The device stress testing had revealed limited capabilities in providing enough scaffolding stability for a certain directional stress condition. To determine the quality of its structural integrity, the device was loaded under direct compressive and tensile load. The strain generated was measured and analysed using a Load-Deformation Curve. The device could support tension close to [3.5 kN], equivalent to standard models, whilst unable to support compression for loads close to [1.2 kN]. The conclusive points that were made had detailed that it was limited by its structural integrity, however the design was evaluated as functionally versatile as and should be further developed. Future recommendations proposed include the addition of constrained joints; improved locking capabilities; implementation of failure modes for hinges and lastly improved structural integrity by using sophisticated materials to further validate the skeletal structure of the fixation system.

Abstract:

There has been a long-standing need in the field of psychotherapy to document progress and show effectiveness. The evidence-based practice (EBP) movement has had considerable influence in the field of psychology as evidenced by the APA task force that adopted the stance of evidence-based practice in psychology (EBPP) to ensure quality and accountability for psychological services as well as the integration of science and practice. One of the primary components of EBPP is the use of routine outcome measures (ROMs), which seek to integrate research with practice while simultaneously documenting progress and enhancing treatment. Despite the wave of ROM in the field, implementation rates have remained low. Research has brought forth many practical and philosophical concerns of therapists using these measures in routine practice including time burden and local validity. The Clinically Adaptive Multidimensional Outcome Survey (CAMOS) was created to directly address clinicians' concerns with a specific focus on concerns of local validity. The CAMOS was designed to monitor several dimensions of functions, thus covering a wide range of issues. In this study the item pool proposed for the CAMOS was factor analyzed, and acceptable fit was found for a 6-factor model that contained 42 items. The 6 factors include (a) psychological distress, (b) relationship distress, (c) therapy expectations, (d) spiritual distress, (e) physical health distress, and (f) work/school distress. It is of note that spirituality emerged as a distinct factor with this data set and the implications and applications are discussed. With this multidimensional foundation, clinicians could more flexibly use the CAMOS to increase local validity. Clinical applications and future directions are discussed.

The design and implementation of an adaptive fuzzy system development system have been investigated in this thesis. The emphasis of the present exercise is on the adaptation of fuzzy systems and implementation of a developing system. In order to incorporate adaptation into fuzzy systems, a refined mathematical model for fuzzy systems is developed in such a way that the fuzzy logical rules in the systems are parameterized. With the simplified model formulation, fuzzy systems can be trained by gradient-based learning methods. To facilitate the software development, the basic concepts and operating modes are described in details. A novel design environment is proposed, which results in a very simple synthesis procedure and speeds up the system development.

As the population of Internet grows, E-learning becomes an evolution of Computer-Assisted Instructions (CAI). In this thesis, we focus on how individual differences and learning styles affect the on-line learning performance, from which a platform for helping teachers in developing adaptive learning courses is proposed. To determine the initial learning styles of the students, Keefe’s questionnaire is employed in our approach. To precisely reflect the actual learning style and talent of each student, the interactions and learning results of each learner are analyzed for adjusting the subject materials. To evaluate the performance of our approach, a test on three groups of learners was performed and the one-way ANOVA was used to analyze all the performance data. The analysis results show that our approach can significantly improve the performance of e-learners.

In this paper, new products development is realized by the adaptive situations and checked by customer’s value (VP value). Both company’s management and its new products development should keep up with the trend to adopt an adaptive strategy. This is the core thinking of this paper. New products are developed by an information procedure and an entity procedure. The research results are summarized as follows: 1. Information procedure stages: Using information as the first stage, evaluates internal and external situations in order to obtain a product conceptual design. Secondly, constructs a matrix of adaptive design strategy to get adaptive product specifications. 2. Entity procedure stages: The last five stages adopt entity procedure. Technology, design, engineering, manufacturing, and marketing were used to deal with five adaptive stages of the new product. In practice, seven product development stages should be worked systematically to explain adaptive strategy for each stage and to achieve new product development. 3. Inspects the adaptive conformity of the new product. Customer’s value (VP value) is used to evaluate the competitive edge of the new product. 4. Proposes three categories of product life cycle to clarify the difference among management, marketing and technical thinking in order to find adaptive effect of a new product and its dynamic adjustment. 5. Proposes eight categories of business management and explains different adaptive thinking in each category. The “adaptive” strategy of this research transcends the limits of macro theory and professional’s parochial thinking. It creates more competitive “adaptive” new products in the market.
