description: The primary aim of this study is to train and evaluate a set of Reduced-Order Models (ROMs) for predicting upper-wing pressure distributions on a civil aircraft configuration. Using wind tunnel data recorded for the Airbus XRF-1 research configuration in the European Transonic Windtunnel (ETW), the ROMs integrate dimensionality reduction and time-evolution components. For dimensionality reduction, both Singular Value Decomposition (SVD) and a convolutional Variational Autoencoder (CNN-VAE) neural network are employed to reduce/encode Instationary Pressure Sensitive Paint (IPSP) data from a transonic buffet flow condition. Fully-Connected (FC) and Long Short-Term Memory (LSTM) neural networks are then applied to predict the evolution of the latent representation, which is subsequently reconstructed/decoded back to its original high-dimensional state.
 
SVD and CNN-VAE are trained on data from five flow conditions and tested on two unseen conditions. When comparing the power spectra of the reconstructed and experimental data, SVD demonstrates marginally better performance. Subsequently, FC and LSTM models are applied for the forward evolution of the reduced/latent representation for one flow condition, resulting in four evaluated ROMs. Among them, the CNN-VAE-LSTM model excels by accurately capturing buffet dynamics, encompassing both transient features and steady-state oscillations. SVD-based models tend to struggle with transient buffet behavior, as they predominantly learn steady-state dynamics. Additionally, the CNN-VAE-LSTM model was employed for an end-to-end training approach. The results suggest that it faces difficulties maintaining dynamics in predictions, demanding further investigation and optimization.

description: Background: Adolescents need to develop health literacy skills to participate in making decisions about their health care. Organizational health literacy facilitates patient understanding of health information, care access, and self-management. Methods: A literature review and qualitative case study were conducted to explore adolescent health literacy within an organizational context of an adolescent scoliosis program. Results: Adolescent health literacy is more nuanced than numeracy and reading levels. Yet, little is known about how organizations (including clinicians) support adolescent health literacy. Interviews with health care professionals in a pediatric tertiary hospital related health literacy to scoliosis patient education but did not address other factors associated with adolescents’ ability to navigate health systems. Organizational documents did not adequately support healthcare professionals in promoting the health literacy of adolescent scoliosis patients. Conclusion: Organizational supports are needed to build health literacy capacity amongst adolescents receiving scoliosis care and clinicians need help to leverage the supports that are in place.

description: When one chooses a main axis of structural decompostion for a software, such as function- or data-oriented decompositions, the other axes become secondary, which can be harmful when one of these secondary axes becomes of main importance. This is called the tyranny of the dominant decomposition. In the context of modular extension, this problem is known as the Expression Problem and has found many solutions, but few solutions have been proposed in a larger context of modular maintenance. We solve the tyranny of the dominant decomposition in maintenance with invertible program transformations. We illustrate this on the typical Expression Problem example. We also report our experiments with Java and Haskell programs and discuss the open problems with our approach.

Online removal of eye movement and blink artifacts from EEG signals without EOG
Creators: name: Noureddin, Borna
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis, two novel methods are presented for online removal of ocular artifacts (OA) from EEG without the need for EOG electrodes attached to the face. Both methods are fully automated and can remove the effects of both eye movements and blinks. The first method employs a high speed eye tracker and three frontal EEG electrodes as a reference to any nonlinear adaptive filter to remove OAs without any calibration. For the filters considered, at some frontal electrodes, using the eye tracker-based reference was shown to significantly (p < .05) improve the ability to remove OAs over using either EOG or only frontal EEG as a reference. Using an eye tracker provides the means for recording point-of-gaze and blink dynamics simultaneously with EEG, which is often desired or required in clinical studies and a variety of human computer interface applications. The second method uses a biophysical model of the head and movement of the eyes to remove OAs. It only requires a short once-per-subject calibration and does not require subject-specific MRI. It was compared to four existing methods, and was shown to perform consistently over a variety of tasks. In removing both saccades and blinks, it removed more than 4 times as much OA as the other methods. In terms of distortion, it was the only method that never removed more power than was present in the original EEG. To carry out the above studies, several related original investigations and developments were needed. These included a novel algorithm to extract the blink time course from eye tracker images, a new measure of OA removal distortion, a high speed eye tracker recording system, a study to determine whether frontal EEG could be used to replace EOG for OA removal and studies of the frequency content of blinks, the effects of an electromagnetic sensor on EEG, and the effects of varying mental states on OA removal methods. In summary this thesis has helped pave the way towards a real-time EEG-based human interface that is free of OAs and does not require EOG electrodes in its operation.

description: The F-GAMMA program is a coordinated effort to investigate the physics of Active Galactic Nuclei (AGNs) via multi-frequency monitoring of Fermi blazars. In the current study we show and discuss the evolution of broad-band radio spectra, which are measured at ten frequencies between 2.64 and 142 GHz using the Effelsberg 100-m and the IRAM 30-m telescopes. It is shown that any of the 78 sources studied can be classified in terms of their variability characteristics in merely 5 types of variability. It is argued that these can be attributed to only two classes of variability mechanisms. The first four types are dominated by spectral evolution and can be described by a simple two-component system composed of: (a) a steep quiescent spectral component from a large scale jet and (b) a time evolving flare component following the "Shock-in-Jet" evolutionary path. The fifth type is characterised by an achromatic change of the broad band spectrum, which could be attributed to a different mechanism, likely involving differential Doppler boosting caused by geometrical effects. Here we present the classification, the assumed physical scenario and the results of calculations that have been performed for the spectral evolution of flares.

description: This dissertation evaluates a need for work. In doing so, it addresses a neglected topic – by systematically exploring the concept of work and its relation to basic needs – and situates that contribution in the context of existing philosophical literature on work and adjacent research in the humanities and social sciences. Second, it offers up new conceptual tools – by arguing for the usefulness of a needs-centred perspective on work – which can aide in our deliberations about how to construct a more human(e) future of work. The project defends an account of a need for work which is grounded in the basic, non-contingent needs we hold, not as individuals, but as a society. It begins by defining work and need, and clarifying the meaning of the question, “Do we need work?” in light of these definitions. It then draws a distinction between the different levels of social life at which we can be understood to hold needs: as individuals, as a community, and as a society. I argue that it is possible, at each of these levels, to ask and answer a different question about work’s relationship to our basic, non-contingent needs. Subsequently, I find that work is important, but not necessary for our ability to meet such needs as individuals and members of a community, since we can do so through non-work activities. It is, however, necessary at the level of society. As a society, we have a need for a shared system of reciprocity to govern how we recognise and communicate about contribution. Work allows us to meet this need by functioning as a signalling mechanism for value. In fulfilling this function, it cannot be straightforwardly replaced by non-work activities, since activities like leisure are not connected to contribution in the same way.

description: The Magnetic cloud boundary layer (BL) is a dynamic region formed by the interaction of the magnetic cloud (MC) and the ambient solar wind. In the present study, we comparatively investigate the proton and electron mean flux variations in the BL, in the interplanetary reconnection exhaust (RE) and across the MC-driven shock by using the Wind 3DP and MFI data from 1995 to 2006. In general, the proton flux has higher increments at lower energy bands compared with the ambient solar wind. Inside the BL, the core electron flux increases quasi-isotropically and the increments decrease monotonously with energy from ~30% (at 18 eV) to ~10% (at 70 eV); the suprathermal electron flux usually increases in either parallel or antiparallel direction; the correlation coefficient of electron flux variations in parallel and antiparallel directions changes sharply from ~0.8 below 70 eV to ~0 above 70 eV. Similar results are also found for RE. However, different phenomena are found across the shock where the electron flux variations first increase and then decrease with a peak increment (>200%) near 100 eV. The correlation coefficient of electron flux variations in parallel and antiparallel directions is always around 0.8. The similar behavior of flux variations in BL and RE suggests that reconnection may commonly occur in BL. Our work also implies that the strong energy dependence and direction selectivity of electron flux variations, which are previously thought to have no enough relevance to magnetic reconnection, could be considered as an important signature of solar wind reconnection in the statistical point of view.

Novel statistical and geometric models for automated brain tissue labeling in magnetic resonance images
Creators: name: Huang, Ko-Kai Albert
Publisher: name: University of British Columbia
Year: 2010

description: Analysis of brain tissues such as white matter (WM), gray matter (GM), cerebrospinal fluid (CSF), and pathological regions from magnetic resonance imaging (MRI) scans of normal adults and patients with neurodegenerative diseases such as multiple sclerosis (MS) allows for improved understanding of disease progression in vivo. As images are often confounded by acquisition noise and partial-volume effects, developing an automatic, robust, and efficient segmentation is essential to the accurate quantification of disease severity. Existing methods often require subjective parameter tuning, anatomical atlases, and training, which are impractical and undesirable. The contributions of this thesis are three-fold. First, a 3D deformable model was explored by integrating statistical and geometric information into a novel hybrid feature to provide robust regularization of the evolving contours. Second, to improve efficiency and noise resiliency, a 3D region-based hidden Markov model (rbHMM) was developed. The novelty of this model lies in subdividing an image into irregularly-shaped regions to reduce the problem dimensionality. A tree-structured estimation algorithm, based on Viterbi decoding, then enabled rotationally invariant estimation of the underlying discrete tissue labels given noisy observations. Third, estimation of partial volumes was incorporated in a 3D fuzzy rbHMM (frbHMM) for analyzing images suffering from acquisition-related resolution limitation by incorporating forward-backward estimations. These methods were successfully applied to the segmentation of WM, GM, CSF, and white matter lesions. Extensive qualitative and quantitative validations were performed on both synthetic 3D geometric shapes and simulated brain MRIs before applying to clinical scans of normal adults and MS patients. These experiments demonstrated 40% and 10% improvement in segmentation efficiency and accuracy, respectively, over state-of-the-art approaches under noise. When modeling partial-volume effects, an additional 30% reduction in segmentation errors was observed. Furthermore, the rotational invariance property introduced is especially valuable as segmentation should be invariant to subject positioning in the scanner to minimize analysis variability. Given such improvement in the quantification of tissue volumes, these methods could potentially be extended to the studies of other neurodegenerative diseases such as Alzheimer’s. Furthermore, the methods developed in this thesis are general and can potentially be adopted in other computer vision-related segmentation applications in the future.

description: The general picture of how thermal AGNs work has become clearer in recent years but major observational puzzles threaten to undermine this picture. These puzzles include AGNs with extremely asymmetric emission line profiles, inconsistent multi-wavelength variability, rapid apparent changes in the sizes of emitting regions and in the direction of gas flow, a curious insensitivity of gas in some narrow velocity ranges to changes in the ionizing continuum, and differing dependencies of polarization on gas velocity. It is proposed that all these puzzles can readily be explained by off-axis variability, and that there is no need to invoke exotic explanations such as binary supermassive black holes or recoiling black holes.

Overview of All Collected Parkinson Networks using the Template Table S3. Overview of the Online Survey About the article: Parkinson's disease is a complex neurodegenerative disease that can be best treated with a multi-disciplinary care approach. Building care networks has been shown as a useful tool to facilitate the integration of care services and improve outcomes for patients and care providers. However, experiences and practices relating to building a network are very limited in the field of Parkinson's disease. This paper portrays existing Parkinson networks in Germany. With the help of a standardized template, a description of networks and their components, so-called modules, were collected from all over Germany. Modules were rated in terms of their expected benefit and the required effort when implementing them, with the help of an expert survey. The rating showed that some modules were perceived as more important than others, but all modules were recognized as beneficial for patients and care providers. Overall, the German experience shows that building a Parkinson network facilitates the integration of care and provides a benefit to all stakeholders involved.

description: Molecular binders play important roles in biology and biotechnology. They are widely used in health, biomaterials and environmental sectors. Protein-based binders have attracted significant interest due to their desirable features like biocompatibility and their potential to be engineered for binding broad range molecule. While protein engineering is a powerful tool, it has not yet been fully exploited to improve functionalities of proteins as binders. Herein, this thesis explores tailoring proteins to suit a variety of different applications including the recovery of small molecules for environmental and diagnostic applications, removal of large and toxic molecules, or neutralization of viruses.

description: During two weeks of nearly continuous optical photometry of the young open cluster NGC 2244 obtained by the MOST satellite, we discovered two new SPB stars, GSC 00154-00785 and GSC 00154-01871. We present frequency analyses of the MOST light curves of these stars, which reveal two oscillation frequencies (0.61 and 0.71 c/d) in GSC 00154-00785 and two (0.40 and 0.51 c/d) in GSC 00154-01871. These frequency ranges are consistent with g-modes of $\ell \leq 2$ excited in models of main-sequence or pre-main-sequence (PMS) stars of masses 4.5 - 5 $M_{\odot}$ and solar composition $(X, Z)= (0.7, 0.02)$. Published proper motion measurements and radial velocities are insufficient to establish unambiguously cluster membership for these two stars. However, the PMS models which fit best their eigenspectra have ages consistent with NGC 2244. If cluster membership can be confirmed, these would be the first known PMS SPB stars, and would open a new window on testing asteroseismically the interior structures of PMS stars.

description: Combinatorial high-throughput methodologies accelerate the discovery of industry-ready candidates for the solar cells of tomorrow. A novel perovskite film fabrication method was developed in this research, making it possible to fabricate perovskite compositional space without human interference in a closely controlled environment. Subsequently, an automated additive concentration screening for better performance and stability of perovskite films was investigated. Furthermore, the ligand-modified, scalable low-temperature deposition of nickel oxide nanoparticles via the employment of the Tesla-valve microfluidic mixer was developed. Moreover, a combinatorial high-throughput PSC characterization setup for standardized and accelerated precise PSC measurements was proposed, serving as the accelerator for rapid screening and discovery of perovskite materials. Lastly, a modular perovskite solar panel prototype was developed to enable real-world application and stability data acquisition of PSCs that can contribute to current and future research efforts and commercialization of PSCs.

Here we compare three non-perturbative reaction theories often used when analyzing breakup experiments, namely the continuum discretized coupled channel model, the time-dependent approach relying on a semiclassical approximation, and the dynamical eikonal approximation. Our test case consists of the breakup of 15C on Pb at 68 MeV/nucleon and 20 MeV/nucleon.

Design of SiGe/Si quantum-well optical modulators
Creators: name: Tasmin, Tania
Publisher: name: University of British Columbia
Year: 2010

description: An electro-optic modulator containing a single SiGe/Si quantum-well has been designed for operation at λ₀= 1.55 µm. This single quantum-well modulator has a lower VπLπ than the 3 quantum-well modulator recently designed and optimized by Maine et al. for operation at λ₀= 1.31 µm, for which the VπLπ product was 1.8 V•cm [25]. Both modulators are derived from the detailed design given for their modulator in [40]. This single quantum-well modulator contains a Si₀.₈Ge₀.₂ quantum-well with Non-Intentionally Doped (NID) and P⁺ highly doped layers on either side. With no field applied, holes from the P⁺ layers are captured by and confined in the quantum-well and when a reverse bias is applied holes are released from the quantum well and drift to the P⁺ contact layer. Variations of the hole distribution lead to changes in the free-carrier absorption and the refractive index of each layer and subsequently to phase modulation of guided TE modes. The VπLπ product of the single quantum-well modulator is estimated 1.09 V•cm for low voltage linear modulation and 1.208 V•cm for 0 to 1.6 V digital modulation, whereas the 3 quantum-well modulator gives a VπLπ of 2.039 V•cm for 0 to 6 V digital modulation for operation at λ₀= 1.55 µm. Also, the optical loss in the single quantum-well (5.36 dB/cm at V=0 V) is lower than that of the 3 quantum-well structure (5.75 dB/cm at V=0 V). This single quantum-well modulator should also offer higher frequency operation than the 3 quantum-well modulator.
Enhancing FAIR compliance: a controlled vocabulary for mapping Social Sciences survey variables

Publisher: name: Zenodo
Year: 2023

description: In Social Sciences surveys, the dynamic relationship among survey instruments and study entities like questionnaires, variables, questions, and response formats evolve. When reusing variables, researchers may need to modify variable attributes such as labels or names, question-wording, or response scales. Therefore, explaining these relations across different waves and studies is necessary to track how variables relate to each other. Although standards like Data Documentation Initiative – Lifecycle (DDI-LC) and DataCite model these relationships, these frameworks fall short of capturing the complexity of variable relationships. The DDI Alliance Controlled Vocabulary for Commonality Type employs codes—such as 'identical,' 'some,' and 'none'—to outline shifts in entities like variables; however, this approach is insufficient for disambiguating these relationships since they do not differentiate the variable attributes subject to change. To bridge this gap, we introduce the GESIS Controlled Vocabulary (CV) for Variables in Social Sciences Research Data. This CV is specifically designed to enhance semantic interoperability across various organizations and systems. By establishing explicit relationships, it not only facilitates harmonization across different study waves but also enriches data reuse. This enhancement supports advanced search and browse functionalities. The CV, published via the CESSDA vocabulary manager, seeks to forge a semantically rich, interconnected knowledge graph specifically tailored for Social Science Research. This endeavour aligns with the FAIR data principles, aiming to foster a more integrated and accessible research landscape.

Schwerpunkte sind unter anderem die Untersuchung des positiven Erlebens, Emotionen, Glücksempfinden, Wohlbefinden und Lebenszufriedenheit. Die Erkenntnisse möchten wir systematisch in die Gestaltungsprozesse von interaktiven Systemen einfließen lassen. Eine Frage von Interessierten ist immer wieder, wie dieses Mindset in Unternehmen integriert werden kann. In diesem Paper möchten wir Probleme und Herausforderungen im Arbeitsalltag aufzählen und mögliche Thesen für Anforderungen zur Diskussion stellen. So können Interessierte Einblicke in die Erfahrungen der Arbeitskreis-mitarbeiter und Gedankenanstöße mitnehmen und entscheiden, ob eine Integration im eigenen Unternehmen damit ermöglicht werden kann.

description: In a constantly evolving digital sphere, surmounting organizational boundaries and sharing data offers the opportunity to realize a multitude of mutual benefits, such as advanced analytics and innovative services. Organizations aspire to share data. However, they struggle to identify and establish beneficial conditions for data sharing, and research still offers little support to exploit the potential of data sharing. We apply an exploratory research approach to develop a framework of beneficial conditions for data sharing. By combining ten expert interviews and a systematic literature review, we aggregate 23 characteristics that constitute beneficial conditions into eight categories and apply and validate the framework in a real-world case. Thus, we contribute to research by providing a fundamental understanding of beneficial conditions for data sharing and a compact target picture. Additionally, we enable practitioners to systematically assess an organization’s current condition to set the course toward exploiting the full potential of data sharing.

description: Das User Requirements Engineering ist das Erarbeiten, Dokumentieren und Priorisieren von konkreten Anfor-derungen an die Nutzung eines interaktiven Systems. Es führt im Idealfall zu erfolgreichen, nützlichen Systemen, Produkten und Dienstleistungen. Usability Praktiker, die eine zentrale Rolle im User Requirements Engineering Prozess ausüben, müssen dabei immer wieder verschiedenste Heraus-forderungen meistern. Beispiele dafür sind mangelnde Akzeptanz, vermeintlich hohe Aufwände und ausgeprägte Zielkonflikte in der Priorisierung von Anforderungen. Ausgehend von diesen Herausforderungen lassen sich Erfordernisse für den Prozess des User Requirements Engineerings selbst identifizieren, die es für Praktiker zu erfüllen gilt, um einen zielführenden und planmäßigen Prozess durchzuführen. Abhängig von verschiedenen Faktoren wie der Branche und der organisationsspezifischen Usability-Reife werden für das User Requirements Engineering Erfordernisse, daraus abgeleitete Anfor-derungen und Lösungsansätze exemplarisch beschrieben und ihre Relevanz in der Praxis aufgezeigt. Für das Erheben des Problemraums der Usability Praktiker beim User Requirements Engineering wird das User Requirements Engineering aus der bekannten Systemebene auf die Prozessebene gebracht. Dieses methodische Vorgehen wird abschließend zusammengefasst und diskutiert.

description: We report on the creation of ultracold 84Sr2 molecules in the electronic ground state. The molecules are formed from atom pairs on sites of an optical lattice using stimulated Raman adiabatic passage (STIRAP). We achieve a transfer efficiency of 30% and obtain 4x10^4 molecules with full control over the external and internal quantum state. STIRAP is performed near the narrow 1S0-3P1 intercombination transition, using a vibrational level of the 0u potential as intermediate state. In preparation of our molecule association scheme, we have determined the binding energies of the last vibrational levels of the 0u, 1u excited-state, and the 1Σ_g^+ ground-state potentials. Our work overcomes the previous limitation of STIRAP schemes to systems with Feshbach resonances, thereby establishing a route that is applicable to many systems beyond bi-alkalis.

description: Fragebögen sind eine einfache Möglichkeit, um mit wenig Aufwand Feedback von größeren Nutzergruppen einzusammeln. Wir zeigen am Beispiel einer komplexen Anwendung, wie man Fragebögen zur kontinuierlichen Qualitätskontrolle einsetzen kann. In unserem Beispiel werden zwei unterschiedlich konzipierte Fragebögen genutzt, um zum einen konkrete Verbesserungsvorschläge zu generieren und zum anderen die UX Qualität in festen Intervallen zu messen. Das Zusammenspiel dieser beiden Instrumente erlaubt einen kontinuierlichen Feedback-Kanal zu etablieren, der einerseits datenbasierte Entscheidungen zur Verbesserung erlaubt und andererseits auch hilft in der Gesamtorganisation die Aufmerksamkeit für UX Qualität zu verbessern.

description: An ironmaking blast furnace (BF) is a type of metallurgical reactor used to produce pig iron. The controlling and optimization of BF operations have been an industry concern, which is however conducted almost empirically. This study presents an integrated mathematical BF model that can be used to examine the effect of various controlling factors on BF performance under different conditions. After validation, the model was extended to multiple applications related to both conventional and innovative operations. This model has proven to be a cost-effective tool that provides systematic optimization strategies of the operating parameters in a comprehensive manner.

description: Ende April 2020 wurden SAP und Deutsche Telekom beauftragt, gemeinsam eine Kontakt-Tracing-App für Deutschland zu entwickeln. Die App ist seit dem 16. Juni 2020 öffentlich verfügbar und im Einsatz. In diesem Beitrag beschreiben wir User Research-Aktivitäten der SAP im Rahmen dieses Projekts mit dem Fokus auf Usability Testing. Durch die gegebene Pandemiesituation lag der Schwerpunkt auf Online-Methoden. Was zunächst nach einer Behinderung aussah, stellte sich als Glücksfall heraus – durch die Online-Arbeitsweise wurden Turn-Around-Zeiten des Tests radikal verkürzt, wodurch eine agile Zusammenarbeit mit den Designern des Projektes erheblich unterstützt wurde. Wir beschreiben Erfahrungen und diskutieren einige methodische Ansätze.

description: We present a search at Jefferson Laboratory for new forces mediated by sub-GeV vector bosons with weak coupling $α'$ to electrons. Such a particle $A'$ can be produced in electron-nucleus fixed-target scattering and then decay to an $e^+e^-$ pair, producing a narrow resonance in the QED trident spectrum. Using APEX test run data, we searched in the mass range 175--250 MeV, found no evidence for an $A'\to e^+e^-$ reaction, and set an upper limit of $α'/α\simeq 10^{-6}$. Our findings demonstrate that fixed-target searches can explore a new, wide, and important range of masses and couplings for sub-GeV forces.

Fluid flows in a librating cylinder

description: The flow in a cylinder driven by time harmonic oscillations of the rotation rate, called longitudinal librations, is investigated. Using a theoretical approach and axisymmetric numerical simulations, we study two distinct phenomena appearing in this librating flow. First, we investigate the occurrence of a centrifugal instability near the oscillating boundary, leading to the so-called Taylor-Görtler vortices. A viscous stability criterion is derived and compared to numerical results obtained for various libration frequencies and Ekman numbers. The strongly nonlinear regime well above the instability threshold is also documented. We show that a new mechanism of spontaneous generation of inertial waves in the bulk could exist when the sidewall boundary layer becomes turbulent. Then, we analyse the librating flow below the instability threshold and characterize the mean zonal flow correction induced by the nonlinear interaction of the boundary layer flow with itself. In the frequency regime where inertial modes are not excited, we show that the mean flow correction in the bulk is a uniform rotation, independent of the Ekman number and cylinder aspect ratio, in perfect agreement with the analytical results of Wang [J. Fluid. Mech., 41, pp. 581 - 592, 1970]. When inertial modes are resonantly excited, the mean flow correction is found to have a more complex structure. Its amplitude still scales as the square of the libration amplitude but now depends on the Ekman number.

description: Luminescent solar concentrators (LSCs) are semitransparent and color adjustable, they can transfer the windows or glass walls into units to produce electricity from solar energy. On the other hand, VO2 smart windows can reduce the consumption of energy for cooling, because they can alleviate the fast increase of indoor temperature when it is hot indoor. This thesis puts forward the designs of tandem LSCs, VO2 smart windows and the combination, aiming to achieve 1) wide range conversion of solar light to electricity, and 2) good ability of saving energy. These designs will make significant contribution to relieve environment problems.

description: An $n$-tuple of operators $(V_1,...,V_n)$ acting on a Hilbert space $H$ is said to be isometric if the row operator $(V_1,...,V_n) : H^n \to H$ is an isometry. We prove that every isometric $n$-tuple is hyperreflexive, in the sense of Arveson. For $n = 1$, the hyperreflexivity constant is at most 95. For $n \geq 2$, the hyperreflexivity constant is at most 6.
