This article discusses the phenomenon of the digital archive, in the context of performance practice and studies, as a potential liminal performance space blurring the boundaries between archive and repertoire (Taylor 2003). It takes the Circus Oz Living Archive as a case study to examine the opportunities and challenges facing cultural organisations wanting to take charge of the multimodal telling of their own histories, as digital technologies impact on practices of remembrance, archiving and performance in the cultural sector. The governing metaphor of the archive shifts from the spatial – a site of recorded memory – to the temporal – an unfolding event of memory. This presents a great challenge for a performing arts company like Circus Oz, which already faces the task of delivering its live show to audiences around the world. How does such a company think through the many issues arising in relation to adding this new digital performance to its repertoire?

St Paul’s Cathedral Precinct in Early Modern Literature and Culture: Spatial Practices is a study of London’s cathedral, its immediate surroundings, and its everyday users in early modern literary and historical documents and images, with a special emphasis on the late sixteenth and early seventeenth centuries. Hentschell discusses representations of several of the seemingly discrete spaces of the precinct to reveal how these spaces overlap with and inform one another spatially. She argues that specific locations—including the Paul’s nave (also known as Paul’s Walk), Paul’s Cross pulpit, the bookshops of Paul’s Churchyard, the College of the Minor Canons, Paul’s School, the performance space for the Children of Paul’s, and the fabric of the cathedral itself—should be seen as mutually constitutive and in a dynamic, ever-evolving state. To support this argument, she attends closely to the varied uses of the precinct, including the embodied spatial practices of early modern Londoners and visitors, who moved through the precinct, paused to visit its sacred and secular spaces, and/or resided there. This includes the walkers in the nave, sermon-goers, those who shopped for books, the residents of the precinct, the choristers—who were also schoolboys and actors—and those who were devoted to church repairs and renovations. By attending to the interactions between place and people and to the multiple stories these interactions tell—Hentschell attempts to animate St Paul’s and deepen our understanding of the cathedral and precinct in the early modern period.

Performance-based, service-life design of wood has been the focus of much research in recent decades. Previous works have been synthesized in various factorized design frameworks presented in the form of technical reports. Factorization does not consider the non-linear dependency between decay-influencing effects, such as between detail design and climate variables. The CLICKdesign project is a joint European effort targeting digital, performance-based specification for service-life design (SLD) of wood. This study evaluates the feasibility of using a semi-empirical moisture model (SMM) as a basis for a digital SLD framework. The performance of the SMM is assessed by comparison against a finite element model (FEM). In addition, two different wood decay models (a logistic, LM, and simplified logistic model (SLM)) are compared. While discrepancies between the SMM and FEM were detected particularly at high wood moisture content, the overall performance of the SMM was deemed sufficient for the application. The main source of uncertainty instead stems from the choice of wood decay model. Based on the results, a new method based on pre-calculated time series, empirical equations, and interpolation is proposed for predicting the service life of wood. The method is fast and simple yet able to deal with non-linear effects between weather variables and the design of details. As such, it can easily be implemented as part of a digital design guideline to provide decision support for architects and engineers, with less uncertainty than existing factorized guidelines.

The paper presents the theory of performance sensitivity distribution and a novel robust parameter design technique. In the theory, a Jacobian matrix describes the effect of the component tolerance to the system performance, and the performance distribution is characterized in the variation space by a set of eigenvalues and eigenvectors. Thus, the feasible performance space is depicted as an ellipsoid. The size, shape, and orientation of the ellipsoid describe the quantity as well as quality of the feasible space and, therefore, the performance sensitivity distribution against the tolerance variation. The robustness of a design is evaluated by comparing the fitness between the ellipsoid feasible space and the tolerance space, which is a block, through a set of quantitative and qualitative indexes. The robust design can then be determined. The design approach is demonstrated in a mechanism design problem. Because of the generality of the analysis theory, the method can be used in any design situation as long as the relationship between the performance and design variables can be expressed analytically.

The intercooled gas turbine obtained by adopting an indirect heat exchanger into an existing gas turbine is one of the candidates for developing high-power marine power units. To simplify such a strong coupled nonlinear system reasonably, the feasibility and availability of qualifying equivalent effectiveness as the only parameter to evaluate the intercooler behavior are investigated. Regarding equivalent effectiveness as an additional degree of freedom, the steady state model of a marine intercooled gas turbine is developed and its off-design performance is analyzed. With comprehensive considerations given to various phase missions of ships, operational flexibility, mechanical constraints, and thermal constraints, the operating curve of the intercooled gas turbine is optimized based on graphical method in three-dimensional performance space. The resulting operating curve revealed that the control strategy at the steady state conditions for the intercooled gas turbine should be variable cycle control. The necessity of integration optimization design for gas turbine and intercooler is indicated and the modeling and analysis method developed in this paper should be beneficial to it.
