The ballet avant-garde II: the ‘new’ Russian and Soviet dance in the twentieth century (2007)

In 1908, a collection of articles on contemporary Russian theatre appeared in St Petersburg. Modestly titled Theatre. A Book on the New Theatre, the volume featured contributions by the painter Alexandre Benois, theatre director Vsevolod Meyerhold, future Commissar of Enlightenment Anatoly Lunacharsky, the symbolist poets Andrey Bely and Valery Bryusov, and novelist Fyodor Sologub. The diversity of this group suggests the significance of Russian theatre in St Petersburg at the turn of the century and the breadth of the quest for new forms in the arts in Russia in the early years of the twentieth century. The writers mostly advocated the latest movement in Russian theatre, shaped as it was by a fascination with emerging symbolist tendencies that sought to correct, or at least to dethrone, the naturalism of Konstantin Stanislavsky's Moscow Art Theatre, though Stanislavsky's innovations were still relatively new.
Design of Broadband Microwave Absorber with 20 dB Absorption Bandwidth (2019)

A simple design configuration has been presented for broadband microwave absorber. The proposed designed structure is made using thin resistive film of indium tin oxide (ITO) to exhibits 20 dB absorption bandwidth in the frequency range of 7.36 GHz to 14.05 GHz with absorptivity nearly 99% at the normal incidence. It is first time when bandwidth is represented with respect to 20 dB of return loss instead of conventional 10 dB of return loss. This makes the design specification really stringent and needs extra attention while designing microwave absorber. Here the proposed structure is polarization insensitive and gives good oblique incidence behavior for both TE and TM. An equivalent circuit model is also derived to study the absorption mechanism of the structure.
Analysis of the Involvement of Hydroxyanthranilate Hydroxycinnamoyltransferase and Caffeoyl-CoA 3-O-Methyltransferase in Phytoalexin Biosynthesis in Oat (2004)

Two oat genes encoding hydroxycinnamoyl-CoA:hydroxyanthranilate N-hydroxycinnamoyltransferase (HHT) and S-adenosyl-L-methionine:trans-caffeoyl-CoA 3-O-methyltransferase (CCoAOMT), both of which are possibly involved in the biosynthesis of oat avenanthramide phytoalexins, were cloned and their expression profiles in response to biological stress were studied. Four distinct cDNAs of oat HHT (AsHHT1-4) were isolated with the degenerative polymerase chain reaction method. The enzymatic activity of AsHHT1 expressed in E. coli was found using hydroxyanthranilate and hydroxycinnamoyl-CoAs as cosubstrates. Cloned oat CCoAOMT (AsCCoAOMT) encoded a polypeptide of 130 amino acid residues with 77.7 to 80.8% identities to the CCoAOMT sequences from other plant species. The accumulation of AsHHT1 and AsCCoAOMT transcripts increased concomitantly with phytoalexin accumulation by the treatment of victorin, a specific elicitor in oat lines carrying the Pc-2/Vb gene. Pharmacological approaches indicated the involvement of Ca2+, NO, and protein kinases in the signaling pathways of AsHHT1 and AsCCoAOMT mRNA induction. When oat leaves were inoculated with Puccinia coronata, the mRNA expression of AsHHT1 and AsCCOAOMT increased in both incompatible and compatible interactions but more rapidly in incompatible interaction. Interestingly, however, significant phytoalexin accumulation was observed only in incompatible interaction during the experimental period, suggesting that phytoalexin accumulation may be inhibited in one or more posttranscriptional processes in the compatible interaction.
Analysing the Robustness of Dual Encoders for Dense Retrieval Against Misspellings (2022)

Dense retrieval is becoming one of the standard approaches for document and passage ranking. The dual-encoder architecture is widely adopted for scoring question-passage pairs due to its efficiency and high performance. Typically, dense retrieval models are evaluated on clean and curated datasets. However, when deployed in real-life applications, these models encounter noisy user-generated text. That said, the performance of state-of-the-art dense retrievers can substantially deteriorate when exposed to noisy text. In this work, we study the robustness of dense retrievers against typos in the user question. We observe a significant drop in the performance of the dual-encoder model when encountering typos and explore ways to improve its robustness by combining data augmentation with contrastive learning. Our experiments on two large-scale passage ranking and open-domain question answering datasets show that our proposed approach outperforms competing approaches. Additionally, we perform a thorough analysis on robustness. Finally, we provide insights on how different typos affect the robustness of embeddings differently and how our method alleviates the effect of some typos but not of others.
Group, Sub-Group, and Nominal Group Idea Generation: New Rules for a New Media? (1994)

How should a group organize itself to generate ideas? Should all group members work together as one intact group, should they form several smaller sub-groups that work independently, or should all members work separately as individuals without communicating? Research with verbal media presents a clear answer: all members should work separately without communicating. This paper examines this question for computer-mediated idea generation. In two separate studies, intact groups generated more ideas (with higher quality) than those working as individuals or in several smaller sub-groups. We attribute these differences to reduced blocking, and different social processes adopted in the different sized groups.
A high precision compact Michelson-Sagnac wavemeter (1987)

A Michelson-type fringe-counting wavemeter is described. A low noise direct carriage drive was constructed that allows interpolation to 1/128 of a wavelength. A total accuracy of some parts in 10-8 is achieved within a scan of only 165 mm. Any erroneous wavelength measurement is suppressed by an appropriate control unit. Small dimensions and automatic error detection allow easy application under various experimental conditions.
Remote Sensing of Glyoxal by Differential Optical Absorption Spectroscopy (DOAS): Advancements in Simulation Chamber and Field Experiments (2006)

Air pollution in many large cities is linked with the photochemical transformation of primary pollutants like VOCs (volatile organic compounds) and NOx, which in the presence of sunlight foster the formation of secondary pollutants including ozone (O3) and secondary organic aerosol (SOA) (Finlayson-Pitts and Pitts 2000; Molina and Molina 2002). ‘Photochemical smog’ has adverse effects on human health (Kunzli et al. 2000; Evans et al. 2002), the ecosystem (Middleton et al. 1950; Gregg et al. 2003) and regional climate (Lelieveld et al. 2001; Ramanathan and Crutzen 2003).
MIMO Broadcast Channels with Finite Rate Feedback (2006)

Multiple transmit antennas in a downlink channel can provide tremendous capacity (i.e. multiplexing) gains, even when receivers have only single antennas. However, receiver and transmitter channel state information is generally required. In this paper, a system where each receiver has perfect channel knowledge, but the transmitter only receives quantized information regarding the channel instantiation is analyzed. The well known zero forcing transmission technique is considered, and simple expressions for the throughput degradation due to finite rate feedback are derived. A key finding is that the feedback rate per mobile must be increased linearly with the SNR (in dB) in order to achieve the full multiplexing gain, which is in sharp contrast to point-to-point MIMO systems in which it is not necessary to increase the feedback rate as a function of the SNR.
Rapid tree model reconstruction for fruit harvesting robot system based on binocular stereo vision (2017)

In this paper, the method of spatial information extraction of tree branch was studied. The region matching method was used to get the disparity map of stereo image, extracted feature points combining with branch skeleton image by multi-segment approximation method, and calculated the spatial coordinates and the radius of branch feature points by using binocular stereo vision. Real-time model reconstruction for fruit tree has been researched on. Test proposed that each branch module was constructed by 12-prism in the coordinate origin, and then rotated twice and translated once to get correct posture, finally combined with other modules for the fruit tree model. Test has optimized extraction algorithm and matching algorithm of the branch region, improved matching rate, reduced matching errors, avoided matching confusion, accurately extracted branch spatial information and improved the success rate of robot path planning for obstacle avoidance.
Design and development of a flexible control laboratory plant for educational purposes (2018)

Theory and practice in control education come together into hands-on laboratories. Control laboratories are commonly composed by a set of didactical plants (typically plants of liquid level control in tanks, temperature control, speed and position control in motors, among others) on which students perform the practical experiences required by the teaching staff. However, given that these plants usually have a fixed structure (normally first or second order models), the creation of control learning activities for different type and order plants are not possible. In this context, this paper presents a flexible educational plant which has been designed as a set of electronic modules based on operational amplifiers which can be combined to create different transfer functions (or plants) and perform PID control on it. This plant is accompanied by a data acquisition system that allows sending and receiving signals to and from the modules and visualizing the results through a graphical user interface developed in LabVIEW. The application also includes an additional tool to compare simulated and real responses for analysis and validation purposes of the designed controllers.
More flexible data types (2003)

XML can play several roles in a distributed object system. In particular, data can be serialized in XML-based formats. XML-encoded data can be more self-describing than data encoded in many more traditional ways, which facilitates the kind of decentralized protocol evolution seen in Internet-scale development: XML's explicit "tagging and bagging" helps keep extensions straight. However, today's common distributed object systems have type systems that are not flexible enough to describe such data. We suggest a way to make more flexible data types; this improves distributed object systems in general, and is critical to realizing XML's full potential. This approach has: (1) typing judgements based on type structure instead of type identity, (2) extensible record types with optional fields, (3) coarse record types, for which extension is compatible with subtyping, and (4) non-ignorable fields in record values.
Calming visual spaces (2002)

Zen gardens exhibit sophisticated visual designs achieved with minimal compositions and engender a calm, contemplative atmosphere. Here we use perceptual models to study Zen garden design with the aim of discovering guidelines for the creation of calm visual spaces.
Zygote: A Framework for Prototyping Smart Devices (2015)

The Internet of Things (IoT), which has had an unprecedented effect in the manufacturing industry, is now becoming increasingly popular in everyday life. Even with the rising interest in IoT among developers, there is no simple way for them to prototype and realize their ideas. As of today, developing an IoT project requires cross domain knowledge of hardware, embedded systems, communication protocols, and cloud and web technologies. We propose and implement the Zygote framework, a browser-based tool to lower the entry barrier and enable rapid prototyping and building of IoT projects. Zygote reduces the time and effort required to do so by providing a visual interface to configure, control and deploy an IoT application. It also exposes a REST API for programmatic control as well as a dashboard for quick data visualization. With its modular architecture, it supports the creation of custom plugins as required by the developer. The Zygote framework enables users to build IoT prototypes in minutes and with virtually zero lines of code.

Perception of video quality at a local spatio-temporal horizon (2022)

This paper contains the research proposal of Andréas Pastor that was presented at the MMSys 2022 doctoral symposium. Encoding video for streaming on Internet has become a major topic to reduce the consumption of bandwidth and latency. At the same time, the human perception of distortions has been explored in multiple research projects, especially for distortions generated by Coder-DECoder (CODEC) algorithms. These algorithms operate in a rate-distortion optimization paradigm to efficiently compress video content. This optimization can be driven by metrics that are most of the time not based on the human perception, and more importantly, not tuned to reflect the local perception of distortions by human eyes.
A Novel Method for Removal of Human Immunodeficiency Virus:Filtration with Porous Polymeric Membranes (1989)

We propose a new method to rid solutions of a virus by using a novel regenerated multilayered structured cellulose membrane (BMM). When the filtrate of human immunodeficiency virus (HIV) preparation was obtained through BMM it showed no infectivity. Electron microscopic observation revealed that HIV was completely caught by the multilayers of the BMM. Conveniently, BMM was seldomly found to adsorb protein molecules and also to have a high filtration rate. These characteristics may have a use in the removal of other variously sized pathogenic agents from plasma.
Multiple Classifier Systems in Offline Cursive Handwriting Recognition (2004)

The thesis addresses the application of multiple classifier systems (MCS) methods in the domain of handwriting recognition. To evaluate the MCS methods two different state-of-the-art handwritten word recognizers are used. Both recognizers are based on Hidden Markov Models (HMMs) and process handwritten words in the same manner: First the word image is normalized in respect to slant, skew and height. Then a sequence of feature vectors is extracted from the image. Finally the HMMs are used to determine the most likely word class from a set of candidate word classes. As the performance of every MCS method depends on the performance of the classifiers it is applied to, the optimization of the recognizers is also addressed in the thesis. There are mainly two kind of MCS methods: The ensemble methods which create several classifiers out of one base classifier and the combination schemes which combine the output of several classifiers to a single output. Both kind of methods are addressed in the thesis. Also the optimal values of the parameters of the MCS methods, such as the number of classifiers created by the ensemble methods, are evaluated in the thesis. There are two objectives of the thesis. The first objective is to the design new MCS methods and the second objective is to evaluate some classic and the new MCS methods in large scale experiments. Four new categories of ensemble methods and two new combination schemes are proposed in the thesis. In addition the adaption of some classic combination schemes for the use with HMM classifiers is addressed. All methods are tested in a handwritten word recognition task where the recognizer, given an image of a word, has to choose a word from 3997 possible word classes.

REAL TIME INJURY AND RELATED ACTIVITIES MONITORING WITH SINGLE ROTATABLE INFRARED SENSOR (2013)

This paper proposed a system to perform injury recognition to assist people with multiple disabilities using single infrared sensor with rotatable capability. Our system will be installed in a room to monitor the disabled for fall, inactivity and help request to recognize injury of people with multiple disabilities. This system alerts the caregiver with alarm, short message (SMS) and a scene snapshot (email), the snapshot assists in verifying false alerts. The designed system is sustainable as it is computationally inexpensive and efficient. The system has the abilities to recognize common human activities. Besides, the system is non-intrusive as there is no wearable device required on the person under monitoring. The system is intuitive as the person or subject under monitoring does not have to press any button for informing and verifying a possible injury.
Relation between cholecystokinin and antral innervation in the control of gastric emptying in the rat. (1997)

Serosal BAC causes lesions in the innervation of the treated region of the stomach. The innervation of the antrum is essential for normal emptying of both liquids and solids, but the inhibition of gastric emptying produced by CCK is not dependent on antral neurons.
Radioimmunoassay for type III procollagen peptide and its application to human liver disease (1979)

A sensitive and specific radioimmunoassay was developed for the precursor-specific peptide segment located at the amino end of bovine type III procollagen. Human material showed high cross-reactivity in this assay. Two forms of human procollagen peptides were detected in body fluids. The larger peptide (45K) was found in serum and ascites, and resembled the whole precursor-specific segment which is presumably released from human type III procollagen by a single enzymatic cleavage. The smaller peptide (10K) was found mainly in urine indicating that further degradation of circulating procollagen peptides is required prior to their passage through the kidney. Compared to peptide concentrations in normal human serum two to twenty-fold increases were observed in all patients with alcoholic liver disease, in fifteen of seventeen patients with acute hepatitis, and in ten of fourteen patients with chronic active hepatitis. Much higher levels were detected in ascites fluid. Patients with rheumatoid arthritis and other diseases showed far smaller elevations of the serum peptide. In alcoholic liver disease peptide levels correlated well with inflammation and necrosis observed in liver biopsies, but not with other laboratory parameters.
Numerical model of the initiation and propagation of a radial flame front by NRP discharge (2023)

View Video Presentation: https://doi.org/10.2514/6.2023-0747.vid This work presents a computational model of 1D radial inflammation and flame propagation by a nanosecond repetitively pulsed discharge (NRP) applied within a cylindrical kernel of given radius. The model incorporates detailed chemistry and 1D transport, while reducing computational costs as much as possible, so that parametric sweeps can be performed. The model is demonstrated in a no-plasma case for ignition by a high-temperature kernel. A test case comparing different NRP ignition strategies is also presented. In this case, the total power budget of the discharge is kept within a narrow range by varying the pulse repetition frequency as the inverse of the square of the plasma region size. The results show that a higher pulse repetition frequency (despite a smaller kernel size) is more energy-efficient in accelerating the ignition phase. The work presented is a work in progress and planned improvements to the model are discussed. Further studies will inform about the relative contributions of plasma kernel size and kinetic effects on relevant quantities for ignition, such as ignition delay times and minimum ignition energies.
Catalytic Asymmetric Transannulation of NH‐1,2,3‐Triazoles with Olefins (2014)

A convenient one-pot asymmetric synthesis of 2,3-dihydropyrroles from in situ generated triflated triazoles and olefins is described that further expands the utility of azavinyl carbene chemistry and provides access to an important class of cyclic enamides. Mechanistic investigations support the involvement of triflated cyclopropylaldimine intermediates in the formation of 2,3-dihydropyrrole. To the best of our knowledge, this is the first example of a chiral Brønsted acid catalyzed rearrangement of cyclopropylimines into enantioenriched 2,3-dihydropyrroles.

Electrical Characterization of Oxynitrided Gate Dielectrics under Constant‐Current Fowler‐Nordheim Stress (1997)

Charge defects in metal oxide semiconductor capacitors formed with oxynitrides are analyzed by Fowler‐Nordheim tunneling injection stress. These oxides are found to incur fewer interface states and lower flatband voltage shifts, the higher the oxynitridation temperature, between 850 and 1050°C. Analysis of oxide traps during constant‐current Fowler‐Nordheim stress uncovers complex phenomena in oxide trap creation. Several features of the data indicate an optimum at an oxynitridation temperature of 850 to 950°C, including initial net‐positive oxide trap creation, and changes in rates of oxide trap creation. However, the net‐negative oxide trapping at high cumulative injected charge simply decreases with higher oxynitridation temperatures. There is evidence that "slow" donor states (or anomalous positive charge) near the interface may be suppressed by this oxide process.
Selective-Tap Adaptive Filtering With Performance Analysis for Identification of Time-Varying Systems (2007)

Selective-tap algorithms employing the MMax tap selection criterion were originally proposed for low-complexity adaptive filtering. The concept has recently been extended to multichannel adaptive filtering and applied to stereophonic acoustic echo cancellation. This paper first briefly reviews least mean square versions of MMax selective-tap adaptive filtering and then introduces new recursive least squares and affine projection MMax algorithms. We subsequently formulate an analysis of the MMax algorithms for time-varying system identification by modeling the unknown system using a modified Markov process. Analytical results are derived for the tracking performance of MMax selective tap algorithms for normalized least mean square, recursive least squares, and affine projection algorithms. Simulation results are shown to verify the analysis.
