This study explores different understandings of culture and creativity in the Finnish urban policymaking. It focuses on the development project of Suvilahti, an old power plant that is transformed into work spaces of cultural producers. As a theoretical background it uses different approaches to culture-led urban development and asks whether a ‘creative policy gap’ exists in Helsinki’s cultural policymaking. By analysing the City of Helsinki’s strategies in the field of cultural policy and semi-structured interviews with a sample of cultural producers, the study finds that a ‘creativity gap’ exists between the understandings of different actors. While planners’ understanding is characterized by the neoliberal understanding of creativity, cultural producers mainly understand creativity through the value of cultural democratization. The study calls for a wider understanding of culture in urban policymaking that recognizes creative activities’ potential also in bringing well-being to the society and understands culture’s intrinsic value.

This paper examines the production of my thesis film, “The Horse and The Castle.” I will explore the choices taken in each step of the production, from the writing process to post-production and finishing. Each area — writing, directing, production design, cinematography, editing, and sound — contained a multitude of decisions that helped to achieve my final vision for the film.

A chair was designed and built through exploration of material and form. Cardboard was chosen as the main material to create the chair. Initially it was paired with concrete and a first study was developed. Cardboard and concrete as materials were too different and did not support each other. Failures in the design and material were noted which informed the next steps of the thesis. Rather than stacking the cardboard, I implemented a quarter iso-grid that required less cardboard, could create more complex forms, and was also able to interface more effectively with other materials. A chair form was designed to be tested. Ultimately, two materials were chosen to compliment the cardboard quarter iso-grid. In the first chair a fiberglass skin was used to cover the cardboard, providing lightweight structural support. The second chair used steel in place of fiberglass. Sections of the cardboard were replaced with steel. The two versions of the chair each had their strengths and weaknesses. The fiberglass was lightweight, strong, and smooth, however it was difficult to work with and the cardboard became less apparent as a part of the chair. On the other hand the steel fit into the quarter iso-grid as a rib element similar to the cardboard making the quarter iso-grid and cardboard more apparent. The steel suffered in strength due to the notches necessary for the quarter iso-grid and had to be reinforced. / Master of Architecture

Active suspension technologies are well known for improving ride comfort and handling of ground vehicles relative to passive suspensions. They are ideally suited for mitigating single-event road obstacles. The work presented in this thesis aims to develop a structured approach for finding the peak force and bandwidth requirements of actuators for active suspensions, to mitigate single-event road obstacles. The approach is kept general to allow for application to different vehicle models, ride conditions and performance objectives. The current state-of-art in active suspensions was first evaluated. Based on these findings, the objectives of the simulation models and approach was defined. A quarter-car model was developed in Matlab to simulate the behavior of active suspensions over unilateral boundary conditions due to different road obstacle profiles. The obstacle profiles were obtained from existing standards and literature and then processed to replicate the interaction of tires on road. A least-mean-squares (LMS) algorithm for adaptive filtering, with the help of look-ahead preview was used to determine the ideal control force profile to achieve the performance objective of the active suspension. A case study was conducted to determine the requirements of the actuator in terms of bandwidth and peak force for different single-event road obstacle profiles, vehicle speeds and look-ahead preview distances. The results of the study show that the vehicle velocity and type of road obstacle have a strong influence on the required peak force and bandwidth of the actuator, while look-ahead preview will be much more important for real time controller implementation. / Master of Science

This study provides a comprehensive performance analysis of Wave-Adaptive Modular Vessels (WAM-V) using simulations and testing data. WAM-Vs are a new class of marine technology that build upon the advantages of lightweight, low-draft, catamaran construction. Independent suspensions above the hulls isolate the passengers and equipment from the harsh sea environment. Enhanced understanding of the relationship between suspension and vehicle performance is critical for future missions of interest to the U.S. Navy. Throughout this study, the dynamic properties of three different WAM-Vs were evaluated. A multi-body dynamics simulation was developed for the 100-ft WAM-V 'Proteus' based on an automotive 4-post shaker rig. The model was used to characterize the sensitivities of different suspension parameters and as a platform for future models. A 12-ft unmanned surface vessel (USV) was instrumented and sea trials were conducted in the San Francisco Bay. A dynamic 4-post simulation was created for the USV using displacement inputs calculated from acceleration data via a custom integration scheme. The data was used to validate the models by comparing the model outputs to sensor data from the USV. A vertical hydrodynamics testing rig was developed to investigate the interaction between the pontoons and the water surface to improve the understanding of how hydrodynamic forces affect suspension performance. A model was created to accurately simulate the hydrodynamic forces that result from vertical pontoon motion. The model was then scaled to fit a 33-ft WAM-V prototype. The 33-ft WAM-V was instrumented and sea trials were conducted in Norfolk, VA. The WAM-V's suspension was upgraded based on the testing results. A 2-post rig was also built for evaluating the 33-ft WAM-V's dynamics. Two dynamic models were made for the 33-ft WAM-V to evaluate different suspension designs. The results from this study have numerous impacts on the naval community and on the development of WAM-Vs. The methodology for testing and evaluation will allow for future WAM-V designs to be compared under controlled circumstances. The performance of WAM-Vs can then be compared against conventional platforms to determine their suitability for future missions. Simulation development will enable future WAM-Vs to be evaluated prior to undergoing sea trials. The hydrodynamic models become a powerful design tool that can be easily scaled and combined with the 4-post models. By providing the simulations and test data to future vessel designers, the designers will be able to intelligently evaluate numerous iterations early in the design phase, improving performance and safety. / Ph.

In this study a real-time open loop estimate of the disturbance displacement input to the tire and an external disturbance force, representing handling and aerodynamic forces, acting on the sprung mass of a quarter-car suspension test rig was generated. This information is intended for use in active control methods applied to vehicle suspensions. This estimate is achieved with two acceleration measurements as inputs to the estimator; one each on the sprung and unsprung masses. This method is differentiated from current disturbance accommodating control, bilinear observers, and preview control methods. A description of the quarter-car model and the experimental test rig is given. The equations of motion for the quarter-car model are derived in state space as well as a transfer function form. Several tests were run in simulation to investigate the performance of three integration techniques used in the estimator. These tests were first completed in continuous time prior to transforming to discrete time. Comparisons are made between the simulated and estimated displacement and velocity of the disturbance input to the tire and disturbance force input to the sprung mass. The simulated and estimated dynamic tire normal forces are also compared. This process was necessary to select preliminary values for the integrator transfer function to be implemented in real-time. Using the acceleration measurements from the quarter-car test rig, a quarter-car parameter optimization for use in the estimator was performed. The measured and estimated tire disturbance input, disturbance input velocity, and dynamic tire normal force signals are compared during experimental tests. The results show that the open loop observer provides estimates of the tire disturbance velocity and dynamic tire normal force with acceptable error. The results also indicate the quarter-car test rig behaves linearly within the frequency range and amplitude of the disturbance involved in this study. The resultant access to the disturbance estimate and dynamic tire force estimate in real-time enables pursuit of novel control methods applied to active vibration control of vehicle suspensions. / Master of Science

For controller design, design of experiments, and other dynamic simulation purposes there is a need to be able to predict the dynamic response and joint reaction forces of a quarter-car suspension. This need is addressed by this study through development and system identification of both a linear and a non-linear multibody dynamics McPherson strut quarter-car suspension model. Both models are developed using a method customary to multibody dynamics so that the same numerical integrator can be used to compare their respective performances. This method involves using the Lagrange multiplier form of the constrained equations of motion to assemble a set of differential algebraic equations that characterize each model's dynamic response. The response of these models to a band-limited random tire displacement time array is then simulated using a Hilber-Hughes-Taylor integrator. The models are constructed to match the dynamic response of a state-of-the-art quarter-car test rig that was designed, constructed, and installed at the Institute for Advanced Learning and Research (IALR) for the Performance Engineering Research Lab (PERL). Attached to the experimental quarter-car rig was the front left McPherson strut suspension from a 2004 Porsche 996 Grand American Cup GS Class race car. This quarter-car rig facilitated acquisition of the experimental reference data to which the simulated data is compared. After developing these models their optimal parameters are obtained by performing system identification. The performance of both models using their respective optimal parameters is presented and discussed in the context of the basic linearity of the experimental suspension. Additionally, a method for estimating the loads applied to the experimental quarter-car rig bearings is developed. Finally, conclusions and recommendations for future research and applications are presented. / Master of Science

This thesis discusses the role and function of the temporary use of urban space within the context of the development process and urban regeneration across the core cities of England. The research utilises the concept of gaps in the cycle of utilisation in land and property to develop a single structured analytical framework to assess the relationship between disuse, interim development as a means to alleviate vacancy and the property development industry. In doing so it attempts to extend existing efforts to interpret temporary urban development by exploring what the thesis comes to define as 'extraordinary' and 'ordinary' forms of short-term reuse. An exploratory, mixed method and multi-scalar approach is used to discuss this dichotomy. Research findings, through a national landscape of the phenomenon of temporary development in the core cities, highlight the characteristics of high profile compared to everyday temporary solutions. In doing so, it exposes the limited frequency of landmark interim solutions in comparison to their more mundane counterparts over a fifteen year period (2000-15). Set against this contextual and temporal backdrop, extraordinary temporary uses are demonstrated to be a marginal but emerging practice of land and property re-use, associated in particular with the aftermath of the financial crisis of 2007-08. Subsequent testing of the spatial distribution and patterning of temporary uses in two selected cities - Bristol and Liverpool - revealed that landmark interim solutions were more commonly centralised in cities than everyday versions, with disproportionately large shares in principal regeneration areas. Through a programme of interviews with key regeneration and development actors, connectivity to urban renewal was shown to be dependent on how the shape and form of local development processes evolve and how regeneration actors' outlooks on temporary use vary over time, as institutional agendas shift and urban economic circumstances change. The thesis explores this shift in the function and emphasis of temporary development in England's second tier cities, from ordinary, everyday forms toward cultural-creative, extraordinary solutions, to discuss the implications of employing high profile short-term uses as mechanisms to incentivise regeneration. Here, the use gap framework developed in this research is shown to be a useful method for conceptualising the rationale behind the variation in stakeholder perspective on temporary development. The model highlights how fluctuating externalities and the interrelating variables of risk, value and time can affect responses taken toward temporary development by the development industry, elucidating a more complete understanding of the role and function of temporary urbanism amongst the wider (re)development process. Ultimately, this thesis argues that while the consensus on temporary use is that it is an effective tactic to assist in the continuation of regeneration, it can also leave some temporary users exposed to the vicissitudes of the market. Extraordinary users bear a disproportionate share of the potential risks associated with development, often without commensurate reward. This illustrates how temporary use can engender opportunity for creativity and innovation as part of the regeneration process, but also, demonstrates how risk-shifting rationalities in the development industry can mean that economic, social and political costs accrue inordinately for temporary users. The research specifies that recognition of the locally specific and multi-dimensional nature of the development process and appreciation of the complexity of the interrelationships between the actors involved are of critical importance in any attempt to understand the role and function of temporary use. It concludes that by understanding the evolution of local structures and actions, over time and across space, the nature and form of temporary development can be better appreciated and strategies to successfully manage it developed.
