Enhanced Kalman Filter-Based Identification of a Fuel Cell Circuit Model in Impedance Spectroscopy Tests
No full textModel parameters identification plays an important role in enhancing the currently available diagnosis techniques for fuel cells (e.g. electrochemical impedance spectroscopy). In this work, the dual Kalman filter (DKF) has been used for the parametric identification of a Randles circuit model. The fuel cell has been stimulated with typical EIS input signals, and the results of the identification have been validated by using the impedance spectra produced by the Fouquet impedance model. The obtained results allow to infer a functional relation between the filter settings and the input signal, thus enabling the possibility of detecting faults by inspecting the deviation of model parameters
Using the Cultural Challenges of Virtual Team Projects to Prepare Students for Global Citizenship
No full textGlobal citizens are those individuals who understand the complex and interdependent nature of the world and who take action to address global issues at a local level. Many faculty members recognize the need to prepare students for the demands of global work and citizenship. In this chapter, the author demonstrates how virtual team projects are an ideal means to help students develop global competency and offers suggestions for faculty seeking to structure projects geared to civic engagement

Using A Course In Global Citizenship To Develop Information Fluency And Global Competency
No full textOur students will face many challenges in today\u27s global marketplace both in their professions and as concerned citizens. To help them succeed we must create courses and assignments that develop both their information fluency and their global competency. This paper describes how an interdisciplinary honors seminar taught by faculty members in Technical Communication and International Relations fostered students\u27 information fluency and global competency. The paper includes specific assignments and activities. Although the sample assignments are all drawn from a global citizenship course, suggestions for adapting the assignments to many other disciplines are given. The author has worked closely with colleagues across the curriculum. In addition to discussing issues relevant to the author\u27s discipline, the paper also explains how information fluency and global competency can be taught to students in many different fields
Multiqubit randomized benchmarking using few samples
No full textRandomized benchmarking (RB) is an efficient and robust method to characterize gate errors in quantum circuits. Averaging over random sequences of gates leads to estimates of gate errors in terms of the average fidelity. These estimates are isolated from the state preparation and measurement errors that plague other methods such as channel tomography and direct fidelity estimation. A decisive factor in the feasibility of randomized benchmarking is the number of sampled sequences required to obtain rigorous confidence intervals. Previous bounds were either prohibitively loose or required the number of sampled sequences to scale exponentially with the number of qubits in order to obtain a fixed confidence interval at a fixed error rate. Here, we show that, with a small adaptation to the randomized benchmarking procedure, the number of sampled sequences required for a fixed confidence interval is dramatically smaller than could previously be justified. In particular, we show that the number of sampled sequences required is essentially independent of the number of qubits and scales favorably with the average error rate of the system under investigation. We also investigate the fitting procedure inherent to randomized benchmarking in light of our results and find that standard methods such as ordinary least squares optimization can give misleading results. We therefore recommend moving to more sophisticated fitting methods such as iteratively reweighted least squares optimization. Our results bring rigorous randomized benchmarking on systems with many qubits into the realm of experimental feasibility.Quantum Information and SoftwareQuantum Internet Divisio
Accessible theatre: the application of human ethology and innate neurobiological systems to full-masked devised theatre practice
No full textThis thesis is concerned with the challenges of devising a full-masked theatre performance that is largely accessible to audiences of every age, social background and culture. The study is original and contributes to knowledge in two distinct ways; it is to this researcher’s knowledge the only such research that examines the relationship between the devising processes of a full-masked performance, neurobiology, human ethology and the accessibility of audience reception (Bennett, 1994). Secondly, this is the first study to investigate how universal innate neurological processes can be used in the making and reception of stage performance to help ensure wide accessibility of information and meaning. The thesis addresses the concept of accessibility by taking a phenomenological approach to devising and audience reception, with particular focus on the role of neurobiological systems and structures, in particular the mirror neuron system, the pleasure-reward system, and pattern recognition systems, in the communication and reception of performance meaning (McConachie, 2008). The research is framed by the concept of a universal theatrical language proposed by practitioners Peter Brook and Tadeshi Suzuki, which has the potential to connect people ‘at the deepest levels of their humanity’ (Pavis, 1996: 6). Practical approaches adopted in the research are informed and supported by anthropological and human ethological claims of universality (Ekman, 1975; Brown, 1991; Eibl-Eibesfeldt; 2007 [1989]; Schmitt et al. 1997). This thesis theorizes that human beings possess innate neurobiological systems that interact with culturally specific concepts, conditions and knowledge in such a way that when deployed appropriately, these innate neurobiological systems can be a platform for human cognition and for the designing of performances accessible to an audience of different ages, social backgrounds and cultures. It also proposes that innate neurobiological systems create a universal framework that makes it possible for the said broad-based audience to read and receive a performance using similar codes of cognition and aesthetic reference irrespective of age, social and cultural backgrounds. The research process led to the creation of an original full-masked theatrical performance and eighteen performances of this piece were given to different audiences in a range of venues and locations in Northamptonshire. Qualitative and quantitative data analysis of how the various audiences received the performance suggest that the devising methods employed did contribute to making the performance accessible to an audience with a ‘broader constituency than theaters normally envision’ (Pitts-Walker, 1994: 9-10). This research enables practitioners for whom a wide audience and accessibility are an explicit focus to adopt devising approaches that will help to achieve the desired wide-ranging reception and accessibility in mixed audiences irrespective of race, age, gender and culture
