How to Improve Your Virtual Experience -- Exploring the Obstacles of Mainstream VR (2019)

What is Virtual Reality? A professional tool, made to facilitate our everyday tasks? A conceptual mistake, accompanied by cybersickness and unsolved locomotion issues since the very beginning? Or just another source of entertainment that helps us escape from our deteriorating world? The public and scientific opinions in this respect are diverse. Furthermore, as researchers, we sometimes ask ourselves whether our work in this area is really "worth it", given the ambiguous prognosis regarding the future of VR. To tackle this question, we explore three different areas of VR research in this dissertation, namely locomotion, interaction, and perception. We begin our journey by structuring VR locomotion and by introducing a novel locomotion concept for large distance traveling via virtual body resizing. In the second part, we focus on our interaction possibilities in VR. We learn how to represent virtual objects via self-transforming controllers and how to store our items in VR inventories. We design comprehensive 3D gestures for the audience and provide an I/O abstraction layer to facilitate the realization and usage of such diverse interaction modalities. The third part is dedicated to the exploration of perceptual phenomena in VR. In contrast to locomotion and interaction, our contributions in the field of perception emphasize the strong points of immersive setups. We utilize VR to transfer the illusion of virtual body ownership to nonhumanoid avatars and exploit this phenomenon for novel gaming experiences with animals in the leading role. As one of our contributions, we demonstrate how to repurpose the dichoptic presentation capability of immersive setups for preattentive zero-overhead highlighting in visualizations. We round off the dissertation by coming back to VR research in general, providing a critical assessment of our contributions and sharing our lessons learned along the way.

A Multianalyte Chemosensor on a Single Molecule: Promising Structure for an Integrated Logic Gate (2008)

A novel fluorescent probe that possess both BODIPY and Rhodamine moieties has been designed for the selective detection of Hg(2+) and Ba(2+) ions on the controlling by a logic gate. The characteristic fluorescence of the Ba(2+)-selective OFF-ON and the Hg(2+)-selective fluorescence bathochromic shift can be observed, and the concept has been used to construct a combinational logic circuit at the molecular level. These results will be useful for further molecular design to mimic the function of the complex logic gates on controlling.
Single DNA molecule grafting and manipulation using a combined atomic force microscope and an optical tweezer (1997)

In this letter, we report on spatially selecting and grafting a DNA-tethered bead to an atomic force microscope (AFM) cantilever, using an optical tweezer. To quantify this technique, we measure force versus extension of a single DNA molecule using AFM. For such studies, we have developed a micromanipulation approach by combining an AFM, an optical tweezer, and visualization setup. The ability to select a single DNA polymer and specifically graft it to a localized position on a substrate opens up new possibilities in biosensors and bioelectronic devices.
Polyoma genome in hamster BHK-21-C13 cells: integration into cellular DNA and induction of the viral replication (1976)

When grown at 39.5 degrees C, BHK-21 C-13 cells transformed by A gene mutants of polyoma virus contain viral sequences that are predominantly associated with cellular DNA pelleted in the Hirt lysis procedure. At this temperature, in cells that are inducible for viral DNA replication (Folk, 1973), the majority of the viral genomes are covalently joined with cellular DNA's containing repetitious sequences. Upon a shift to 31 degrees C, free viral genomes appear and are replicated. Coupled with the replication of the free viral genomes at 31 degrees C is an increase in the viral genomes associated with cellular DNA.
Integration of Robust Header Compression over (2010)

IP Security (IPsec) provides various security services for IP traffic. However, the benefits of IPsec come at the cost of increased overhead. This document outlines a framework for integrating Robust Header Compression (ROHC) over IPsec (ROHCoIPsec). By compressing the inner headers of IP packets, ROHCoIPsec proposes to reduce the amount of overhead associated with the transmission of traffic over IPsec Security Associations (SAs).
Effects of Beverages on Alcohol Metabolism: Potential Health Benefits and Harmful Impacts (2016)

Nonalcoholic beverages are usually consumed accompanying alcoholic drinks, and their effects on alcohol metabolism are unclear in vivo. In this study, the effects of 20 nonalcoholic beverages on alcohol metabolism and liver injury caused by alcohol were evaluated in mice. Kunming mice were orally fed with alcohol (52%, v/v) and beverages. The concentrations of ethanol and acetaldehyde in blood as well as the activities of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) in liver were assessed to indicate alcohol metabolism. The levels of aspartate aminotransferase (AST) and alanine transaminase (ALT) in serum as well as the levels of malonaldehyde (MDA) and superoxide dismutase (SOD) in liver were measured to reflect the alcohol-induced liver injury. The results showed that the treatment of soda water, green tea and honey chrysanthemum tea could accelerate ethanol metabolism and prevent liver injuries caused by alcohol when companied with excessive alcohol drinking. They might be potential dietary supplements for the alleviation of harmful effects from excessive alcohol consumption. On the contrary, some beverages such as fresh orange juice and red bull are not advised to drink when companied with alcohol consumption due to their adverse effects on ethanol induced liver injury.
Use of gold as a routine and long term preservative for mercury in potable water, as determined by ICP-MS (1999)

A study was made of the effects of storing both deionised and potable water spiked with mercury in both glass and poly(ethylene terephthalate) (PET) containers, using gold as a preservative. Bulk solutions of mercury at three different concentrations ( 0.5, 1.0 and 1.5 µg l–1) were prepared separately in deionised (DI) water and locally obtained potable water. Individual glass and PET bottles containing gold, as gold chloride solution, were filled with these solutions and then analysed over a four week period, by ICP-MS. Details of the ICP-MS operational criteria are given in the text. The results show that there was little difference in mercury recovery from any of the solutions used when stored in either the glass or the PET containers during the study. The maximum/minimum recoveries for each system spiked at 1 µg l–1 Hg were: glass–DI water 103/93%; glass–potable water, 106/96%; PET + gold–DI water, 103/97%; PET + gold–potable water, 106/99%. This establishes the effectiveness of gold as a preservative agent for mercury in potable water up to a concentration of 1.0 µg l–1 Hg, adequately covering the range up to the Prescribed Concentration or Value (PCV) required by UK legislation. The effect of the gold on the analysis of other low concentration metals in potable water using ICP-MS was studied and recoveries ranging from 92–103% were obtained in its presence. The determination of mercury using the cold vapour fluorescence technique was affected by the presence of the gold chloride. All mercury containing solutions and standards were matrix matched to potable water by the addition of calcium, potassium and sodium salts.
ANN-based QRS-complex analysis of ECG (1998)

Reliable detection the QRS complex in either a normal or an abnormal ECG and its analysis is the first and foremost task in almost every ECG signal analysis system aimed at the diagnostic interpretation of ECG. Conventionally, detection of the QRS complex is accomplished using a rule-based/algorithmic approach. This work, uses the learn and generalize approach of an artificial neural network (ANN) for the detection of QRS complexes in either a normal or an abnormal ECG. This is followed by the analysis of the QRS complex to designate and measure the morphological components within the QRS complex in all 12 standard leads. An ANN has been developed to detect the QRS complex in ECG and trained, with the help of back propagation algorithm, on more than a hundred ECGs selected from the CSE Data Set-3. The trained ANN was tested on all the recordings of the CSE Data Set-3 and the sensitivity has been found to be 99.11%. Subsequent to the identification of the QRS complex, an analysis of this complex and measurement of peak amplitudes of the component waves is done. The results are validated using the CSE multilead measurement results. Both the QRS detection and the QRS analysis software developed in C-language have been successfully implemented on a PC-AT. The results are found to be in agreement with visual measurements carried out by medical experts.
Polarization properties of Rayleigh backscattering in single-mode fibers (1993)

The state and degree of polarization (SOP, DOP) of Rayleigh backscattered light in low birefringent optical fibers was calculated using Stokes calculus. It was found that the SOP of Rayleigh backscattered light in low birefringent fiber is constant, viz. the same as the SOP of the incoming light. The DOP of Rayleigh backscattered light is one-third of the DOP of the incoming light, and not just anywhere between 0 and 100% as often mentioned in the literature. The experimental results agree with the calculations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Hole Defects and Nitrogen Doping in Graphene: Implication for Supercapacitor Applications (2013)

One great challenge for supercapacitor is to achieve high energy capacity and fast charge/discharge rates simultaneously. Porous graphene with large surface area is a promising candidate for electrode materials of supercapacitor. Using first-principles calculations and non-equilibrium Green's function technique, we have explored the formation energies, mechanical properties, diffusion behaviors and electrical conductance of graphene sheets with various hole defects and/or nitrogen doping. Interestingly, graphene sheets with pyridinic-like holes (especially hexagonal holes) can be more easily doped with nitrogen and still retain the excellent mechanical properties of pristine graphene that is beneficial for the long cycle life. Porous graphene electrode with moderate hole diameter of 4.2-10 Å facilitates efficient access of electrolyte and exhibit excellent rate capability. In addition, doping with nitrogen as electron donors or proton attractors leads to charge accumulation and generates higher pseudocapacitance. Transmission coefficients of N-doped graphene sheets with pyridinic-like holes are only moderately reduced with regard to that of pristine graphene and are insensitive to the detailed geometry parameters. Overall, N-doped graphene with pyridinic-like holes exhibits exciting potentials for high performance energy storage in supercapacitor devices.
Airline reservations forecasting--probabilistic and statistical models of the booking process (1990)

In this thesis, we develop the necessary statistical framework to produce accurate forecasts of total bookings in a particular fare class on a specific flight number departing on a given date at various points before departure. After an introduction to the basic terminology of the airline booking process, a rigorous probabilistic model is developed. The booking process is modeled as a stochastic process with requests, reservations, and cancellations interspersed in the time before a flight departs. The key result of the probabilistic analysis is a censored Poisson model of the airline booking process. A comprehensive statistical framework views the booking process from a data analysis perspective. We describe models based on advance bookings (the traditional booking curve) and historical bookings (a traditional time series model). An important development is the
Synthesis of imidazolin‐2‐ones by rearrangement of <i>N</i>‐carbamoyliminium salts derived from 4‐hydroxyimidazolidin‐2‐ones (1989)

Abstract The action of trifluoroacetic acid on 4‐hydroxyimidazolidin‐2‐ones 9a,b,c induces the formation of N ‐carbamoyliminium salts 10a,b,c which rearrange to imidazolin‐2‐ones 11a,b,c. The reactions proceed in high yield at ambient temperatures.
Microcontroller Based Automated Water Level Sensing and Controlling: Design and Implementation Issue (2010)

Abstract—In this paper we introduce the notion of water level monitoring and management within the context of electrical conductivity of the water. More specifically, we investigate the microcontroller based water level sensing and controlling in a wired and wireless environment. Water Level management approach would help in reducing the home power consumption and as well as water overflow. Furthermore, it can indicate the amount of water in the tank that can support Global Water types including cellular dataloggers, satellite data transmission systems for remote water monitoring system. Moreover, cellular phones with relative high computation power and high quality graphical user interface became available recently. From the users perspective it is required to reuse such valuable resource in a mobile application. Finally, we proposed a web and cellular based monitoring service protocol would determine and senses water level globally. Index Terms—Conductivity, indicator, microchip, nozzle, and water level sensor.
ECVAM's Contributions to the Implementation of the Three Rs in the Production and Quality Control of Biologicals (2002)

A summary is presented of the activities initiated, and the progress achieved, between April 1993 and December 2001 in implementing the Three Rs in one of the main priority areas of the European Centre for the Validation of Alternative Methods (ECVAM) - the production and quality control of biologicals. These have included organising eight key workshops, and financial contributions to, and sponsorship of, relevant international workshops, symposia and conferences. Noteworthy activities include financial support and/or participation in a number of prevalidation and validation studies. These involved alternative methods for the batch potency testing of: human tetanus vaccines; human and veterinary tetanus antisera and immunoglobulin; rabies vaccines; Leptospira hardjo vaccines; Clostridium perfringens vaccines; and erysipelas vaccines. They also involved a cell culture test for specific toxicity testing of diphtheria toxoid vaccines. In addition, ECVAM funded a study on the use of humane endpoints for vaccine quality control tests involving severe suffering, such as the potency testing of erysipelas, rabies and pertussis vaccines. ECVAM has also contributed financially to the compilation of manuals and expert reports, and to training in test methods. Following the report of an ECVAM Task Force, ECVAM financially supported the prevalidation of some in vitro methods for the potency testing of a recombinant hormone. A proposal is presented for promotion of regulatory acceptance, and suggestions are made for possible future activities.
Biomechanical analysis of sprinting: decathletes versus champions. (1981)

The purpose of this study was to compare some biomechanical variables of decathletes and world class sprinters while running the 100 metre race. Sixteen Swiss national decathletes and three world class American sprinters were filmed by a 16 mm Locam (100 fps) camera at the 70 m mark of the race. The co-ordinates for a 26-point stick figure were digitised and then submitted to analysis by a computer programme which produced quantitative data for 12 biomechanical variables. The data indicated that world-class sprinters differed from decathletes in running the 100 m dash by having (1) an optimal combination of a larger stride length and higher stride frequency (2) a smaller thigh angle at contact which shortens the contact time (3) a larger stride landing angle (4) a greater average acceleration of the thigh angle was (5) a larger trunk angle which contributes to a larger trunk/thigh angle. Although other factors such as culture, training, physique and racial differences may influence differences in performance between American world-class sprinters and Swiss decathletes, these data do indicate that biomechanical variables may contribute to differences in 100 m dash performance.

<title>Approximation of sweep surfaces by tensor product NURBS</title> (1992)

Methods for approximating sweep surfaces by tensor product NURBS are presented. Sweep surfaces are generated by sweeping a (possibly deforming) NURBS cross-section curve along a NURBS axis curve. A general form for NURBS approximation to sweep surfaces is derived and expressed in terms of the approximation to a set of offset curves of the axis curve. The actual algorithm used to construct the surface approximation depends on the nature of the desired deformation and change in orientation that the cross-section undergoes as it is swept along the axis.

What Limits Lean Operation in Spark Ignition Engines-Flame Initiation or Propagation? (1976)

<div class="htmlview paragraph">The lack of clearly identified constraints for ignition and flame propagation has hindered understanding the processes which limit lean operation in spark ignition engines. This experimental study explores flame initiation and flame propagation as limits of lean operation in engines.</div> <div class="htmlview paragraph">In separate tests conducted in a single-cylinder CFR (cooperative fuel research) engine, the spark timing was either advanced or retarded from MBT<span class="xref">*</span> in order to determine the ignition-limit or partial-burn-limit spark timings, respectively. These two limiting spark timings were found to converge at lean mixtures. At the MBT lean misfire limit, the ignition-limit, and the partial-burn-limit spark timing lines converged. Apparently flame initiation as well as flame propagation considerations constrain lean operation. The effects of engine and ignition system-related variables on the ignition and partial-burn limits are presented and discussed.</div>

Low-Energy Optical Absorption Peak in Aluminum and Al-Mg Alloys (1970)

Measurements of the absorptivity of Al and dilute Al-Mg alloys were made at 4.2 K in the 0.2- to 5-eV energy region by a calorimetric technique. In addition to the well-known conductivity peak around 1.6 eV, another peak has been found near 0.5 eV. These peaks are present in the alloys, broadened, but unshifted, as well as in Al. The peaks are at about $2|{V}_{200}|$ and $2|{V}_{111}|$, respectively, where the $V$'s are Fourier coefficients of the pseudopotential.
