EventSpaces. A Multi-Author Game And Design Environment (2000)

EventSpaces is a web-based collaborative teaching environment we developed for our elective CAAD course. Its goal is to let the students collectively design a prototypical application - the EventSpaces.Game. The work students do to produce this game and the process of how they interact is actually a game in its own right. It is a process that is enabled by the EventSpaces.System, which combines work, learning, competition and play in a shared virtual environment. The EventSpaces.System allows students to criticize, evaluate, and rate each otherÃs contributions, thereby distributing the authorship credits of the game. The content of the game is therefore created in a collaborative as well as competitive manner. In the EventSpaces.System, the students form a community that shares a common interest in the development of the EventSpaces.Game. At the same time they are competing to secure as much credit as possible for themselves. This playful incentive in turn helps to improve the overall quality of the EventSpaces.Game, which is in the interest of all authors. This whole, rather intricate functionality, which also includes a messaging system for all EventSpaces activities, is achieved by means of a database driven online working environment that manages and displays all works produced. It preserves and showcases each authorÃs contributions in relation to the whole and allows for the emergence of coherence from the multiplicity of solutions. This Paper first presents the motivation for the project and gives a short technical summary of how the project was implemented. Then it describes the nature of the exercises and discusses possible implications that this approach to collaboration and teaching might have.
From Machine-to-Machine Communications to Internet of Things: Enabling Communication Technologies (2017)

The term Internet of Things (IoT) was first coined by Kevin Ashton in the late 90s, but in reality, IoT goes back a lot further than that. IoT has a wide range of applications in various sectors and domains. The applications can improve the ways people live, provide better interactions with the environment and facilitate the growth in the economy. IoT systems are generally comprised of devices, or objects that need to exchange data with each other, or with a central server. The advantage of this topology is the high level of reliability as the applications can run even if the Internet access fails. Bluetooth is a low cost wireless technology for establishing personal area networks (PANs) over short distances, typically less than 100 m. Radio-frequency identification (RFID) technologies were initially designed to provide short-range connectivity for the purpose of identification, utilized in various domains such as logistic, manufacturing, health-care, security, and access control.
Syntheses of New Quarternary Ammonium Iodides as Plant Growth Retardants and Their Biological Activities (1978)

Twelve new quarternary ammonium compounds were synthesized and their plant growth retarding activities were examined. Among the candidates, N,N,N-trimethyl-l-methyl-3-(3′,3′5′-trimethylcyclohexyl)- and N,N,N-trimethyl-l-methyl-3-(3′,3′,5′,5′-tetramethylcyclohexyl)-2-propenylammonium iodides were the most effective to suppress the growth of rice and cucumber seedlings, and their activities were far stronger than those of any growth retardants hitherto known.
Epigenetic regulation of neural cell differentiation plasticity in the adult mammalian brain (2008)

Neural stem/progenitor cells (NSCs/NPCs) give rise to neurons, astrocytes, and oligodendrocytes. It has become apparent that intracellular epigenetic modification including DNA methylation, in concert with extracellular cues such as cytokine signaling, is deeply involved in fate specification of NSCs/NPCs by defining cell-type specific gene expression. However, it is still unclear how differentiated neural cells retain their specific attributes by repressing cellular properties characteristic of other lineages. In previous work we have shown that methyl-CpG binding protein transcriptional repressors (MBDs), which are expressed predominantly in neurons in the central nervous system, inhibit astrocyte-specific gene expression by binding to highly methylated regions of their target genes. Here we report that oligodendrocytes, which do not express MBDs, can transdifferentiate into astrocytes both in vitro (cytokine stimulation) and in vivo (ischemic injury) through the activation of the JAK/STAT signaling pathway. These findings suggest that differentiation plasticity in neural cells is regulated by cell-intrinsic epigenetic mechanisms in collaboration with ambient cell-extrinsic cues.
Heat extraction from the ANL research salt gradient solar pond (1986)

This report documents the design considerations and test results of two heat extraction systems for the ANL Research Salt Gradient Solar Pond (RSGSP). Since operation began in November 1980, the RSGSP has been used to study a wide variety of solar pond phenomena, and the behavior of the RSGSP without heat extraction has been well characterized. Heat extraction equipment was installed in the spring of 1984, with heat extraction experiments conducted the following summer and fall and in the fall of 1985. The experiments simulated the use of the solar pond for grain drying. Two methods of heat extraction are compared. For both methods the heat exchangers are sized for 30 kW, with a peak load capability of 60 kW. In the first method, ethylene glycol solution is circulated through a plastic-tube heat exchanger submerged in the pond to a liquid-to-air fin-tube heat exchanger external to the pond. In the second method, hot brine is withdrawn from the bottom of the pond, circulated through a brine-to-air heat exchanger, and the cooled brine is returned to the bottom of the pond. The brine-to-air heat exchanger is constructed from copper-nickel to minimize corrosion. The effects of both heat extraction methods on the stability of the salt gradient are investigated.

Beyond Inflation: A Cyclic Universe Scenario (2005)

Inflation has been the leading early universe scenario for two decades, and has become an accepted element of the successful `cosmic concordance' model. However, there are many puzzling features of the resulting theory. It requires both high energy and low energy inflation, with energy densities differing by a hundred orders of magnitude. The questions of why the universe started out undergoing high energy inflation, and why it will end up in low energy inflation, are unanswered. Rather than resort to anthropic arguments, we have developed an alternative cosmology, the cyclic universe, in which the universe exists in a very long-lived attractor state determined by the laws of physics. The model shares inflation's phenomenological successes without requiring an epoch of high energy inflation. Instead, the universe is made homogeneous and flat, and scale-invariant adiabatic perturbations are generated during an epoch of low energy acceleration like that seen today, but preceding the last big bang. Unlike inflation, the model requires low energy acceleration in order for a periodic attractor state to exist. The key challenge facing the scenario is that of passing through the cosmic singularity at t = 0. Substantial progress has been made at the level of linearised gravity, which is reviewed here. The challenge of extending this to nonlinear gravity and string theory remains.
Photodynamic Therapy with A Cationic Functionalized Fullerene Rescues Mice From Fatal Wound Infections (2010)

Aetiology of diarrhoea in adequately nourished young African children in Durban, South Africa (1984)

Two inter-related hospital-based studies on the causes of diarrhoea in African children who were not overtly malnourished, were performed over a period of two years in Durban, South Africa. The first study involved 126 inpatients selected for previously untreated diarrhoea of less than 96 h duration. On examination and culture of the stools of these children bacteria were identified in 60%, rotavirus in 20% and parasites in 4%. No pathogens were identified in 33%. The bacteria most frequently encountered were Campylobacter jejuni (21%), enteropathogenic Escherichia coli (EPEC) (18%), enterotoxigenic Escherichia coli (ETEC) (11%) and salmonella (8%). Of those cases having an identifiable cause 16% had more than one organism. The majority of children had mild disease and recovered clinically in 5.4 (1.3) days (Mean (s.d.]. The second study included 352 outpatients with diarrhoea who were randomly selected without regard to duration of disease or prior treatment. The results of faecal investigations were as follows: 28% had bacterial pathogens, 34% rotavirus, 15% parasites and 61% no pathogens. The bacteria most frequently detected were C. jejuni 7%, EPEC 7%, salmonella 6%, and shigella 5%. Ten per cent of positive cases had more than one pathogen. The most likely reason for the higher percentage with no identifiable pathogen is the prolonged duration of diarrhoea in 19% for more than seven days. In 128 control children with diarrhoea, stool samples were investigated during the same period as the two studies: 13% had bacteria, 2% rotavirus and 14% parasites. The bacteria involved were C. jejuni (5%). EPEC (5%), salmonella (2%) and shigella (2%).
Analysis of a Multi-Oscillated Current Resonant Type DC-DC Converter (2008)

This paper presents the analysis of a new multi-oscillated current resonant type DC-DC converter. Current resonant converters have several remarkable features such as high efficiency, small size, low cost and low noise, and are frequently employed in many portable electronic systems such as personal computers, cellular phones and flat panel displays. The current resonant type converter generally employs pulse frequency modulation for constant voltage control in the output. For this reason, the magnetizing current through the converter not only causes a power loss under a light load, but also a loss during stand-by. Therefore, this type of converter has a problem in that the required smaller size cannot be achieved, because an auxiliary source is necessary for stand-by. In order to solve these problems, a new current resonant type power supply is proposed in which two driving methods are employed. In these driving methods, one MOSFET as a main switch is driven by an auxiliary winding of the transformer and another MOSFET as a main switch is driven by the driving IC with a low withstand voltage. Good agreement of the observed and simulated waveforms was confirmed. In addition, eight distinct states and four distinct operating modes, which compose of the sequence of states, were clarified by experimental and simulated analysis.
Simultaneous solvent screening and reaction optimization in microliter slugs (2015)

An automated, continuous flow droplet screening system is presented, enabling real-time simultaneous solvent and continuous variable optimization. An optimal design of experiments strategy is applied to the alkylation of 1,2-diaminocyclohexane in 16 μL droplets, with scale-up demonstrated. Analysis of segmented flow results suggests correlation of yield with solvent hydrogen bond basicity.
The Synthesis of Functional Cobalt Oxide Nanostructures, and their Sensitive Glucose Sensing Application (2016)

Abstract In this study, a novel approach is adapted for the synthesis of new nanostructures of cobalt oxide (Co 3 O 4 ) by low temperature aqueous chemical growth method in the presence of water soluble amino acids such as L‐arginine, L‐aspartic acid, L‐isoleucine, L‐leucine, L‐serine and L‐threonine. The synthesized nanostructures were characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM). The nanostructures exhibit well defined morphology and are of high purity. To explore the potential application of the prepared nanostructures of cobalt oxide, the non‐enzymatic glucose sensor is developed by modifying the glassy carbon electrode. Serine assisted cobalt oxide nanostructures showed excellent sensitivity of 4169.00 μA/mM cm 2 , wide linear range of 0.01 mM to 20 mM and detection limit was estimated as 0.001 mM (S/N=3). The analytical parameters for the serine assisted cobalt oxide nanostructures based glucose sensor were evaluated and it was found that the sensor is highly selective, reproducible, repeatable, reversible, and stable. Finally, the practical application of the serine assisted cobalt oxide nanostructures based glucose sensor was examined by measuring the glucose concentrations from real human blood samples.

The Second-Generation of HiSIM_HV Compact Models for High-Voltage MOSFETs (2012)

This paper reviews the industry-standard surface-potential-based compact model HiSIM_HV for high-voltage MOSFETs, as, e.g., the lateral double-diffused MOS transistor, and introduces important improvements implemented in the second-generation model versions (HiSIM_HV2), for which open source code has been released since October 2011. HiSIM_HV solves the Poisson equation consistently within the intrinsic MOSFET, i.e., the gate-drift overlap region and the drain-side part of the drift region. Excess carrier concentrations in the drift region are accurately considered together with the velocity saturation effect. These modeling concepts enable a scalable compact model formulation with only one internal node. Fulfillment of the current continuity between MOSFET and drift parts is required for determining the internal node potential. An important enhancement implemented in the HiSIM_HV2 models is a physically accurate compact drift region resistance model, which captures the effects of the structure-dependent 2-D current flows in overlap and drift regions with their complicated bias dependence. Furthermore, compact modeling of gate overlap capacitance, leakage currents due to, e.g., impact ionization, self-heating, noise, and symmetry properties (smooth derivatives at zero drain-source voltage) have been substantially improved.
Boundary-Active-Only Adaptive Power-Reduction Scheme for Region-Growing Video-Segmentation (2006)

This letter presents a boundary-active-only (BAO) power reduction technique for cell-network-based region-growing video segmentation. The key approach is an adaptive situation-dependent power switching of each network cell, namely only cells at the boundary of currently grown regions are activated, and all the other cells are kept in low-power stand-by mode. The effectiveness of the proposed technique is experimentally confirmed with CMOS test-chips having small-scale cell networks of up to 41 × 33 cells, where an average of only 1.7% of the cells remains active after application of the proposed approach. About 85% power reduction is thus achievable without sacrificing real-time processing.
3D-Formvermessung mittels Zwei-Wellenlängen-ESPI-Technik (1994)

A system for three-coordinate measurement will be presented which is suitable for the contouring of rough surface objects.The system is based on the combination of the methods of source transformation and wavelength shift.This makes it possible to illuminate and to view the object without shading. The generation of a synthetic wavelength by suitably choosing the difference of the wavelengths allows a variable sensitivity and hence an adjustment to the contour to be measured.The maximum accuracy of the system will be stated.First results with objects having a diameter of less than 5 cms will be shown.
Fecal Viral Load and Norovirus-associated Gastroenteritis (2006)

Abstract We report the median cDNA viral load of norovirus genogroup II is >100-fold higher than that of genogroup I in the fecal specimens of patients with norovirus-associated gastroenteritis. We speculate that increased cDNA viral load accounts for the higher transmissibility of genogroup II strains through the fecal-oral route.
Design of a Finger Ring Extremity Dosemeter Based on OSL Readout of alpha-Al2O3:C (2002)

A finger-ring dosemeter and reader has been designed that uses OSL readout of alpha-Al2O3:C (aluminium oxide). The use of aluminium oxide is important because it allows the sensitive element of the dosemeter to be a very thin layer that reduces the beta and gamma energy dependence to acceptable levels without compromising the required sensitivity for dose measurement. OSL readout allows the ring dosemeter to be interrogated with minimal disassembly. The ring dosemeter consists of three components: aluminium oxide powder for measurement of dose, an aluminium substrate that gives structure to the ring, and an aluminised Mylar cover to prevent the aluminium oxide from exposure to light. The thicknesses of the three components have been optimised for beta response using the Monte Carlo computer code FLUKA. A reader was also designed and developed that allows the dosemeter to be read after removing the Mylar. Future efforts are discussed.
Integrated Cluster Environment (ICE) : plataforma de gerenciamento e de acesso a múltiplos clusters (2006)

Facilitar o gerenciamento e o acesso a sistemas de alto desempenho vem sendo uma área de pesquisa explorada nos últimos anos. Isto acontece uma vez que se verifica o aumento do número de usuários, muitos pertencentes a outras áreas, como por exemplo, biologia, geologia, hidrologia, etc e, desta forma, é preciso facilitar os meios de interação destes usuários com tais sistemas, assim como melhorar as técnicas de gerenciamento dos mesmos. Além do aumento do número e da multidisciplinaridade desses usuários, existe também o fato de que grande parte deles tem acesso a diferentes tipos de sistemas de alto desempenho. Em geral, estes sistemas possuem ferramentas não padronizadas, sendo que cada uma apresenta uma interface e um conjunto de ações e comandos a serem realizados para que possam dispor de suas funcionalidades. Este trabalho propõe a definição de uma arquitetura de gerenciamento e acesso a múltiplos clusters, que seja capaz de ser facilmente extensível, transparente, interoperável e de fácil utilização configuração e manutenção. Como resultado da arquitetura proposta, foi desenvolvido um protótipo, denominado ICE - Integrated Cluster Environment. Os principais objetivos da arquitetura e do ambiente ICE são: (i) capacidade de uniformização do modo como as ferramentas de clusters são utilizadas e, também, uniformização na maneira como os clusters são acessados; (ii) transparência na forma de acesso e uso dos clusters; e (iii) capacidade de extensibilidade em dois níveis: o primeiro refere-se á extensibilidade do número de funcionalidades (serviços) providos pelo sistema e o segundo está relacionado á capacidade do sistema lidar com o uso de diferentes ferramentas que possuem a mesma funcionalidade. Além da descrição da arquitetura e do protótipo, neste trabalho, também é realizada uma avaliação do ambiente ICE. Essa avaliação foi dividida em dois momentos. O primeiro traz a comparação das características do ambiente proposto com algumas ferramentas relacionadas. No segundo momento são apresentados alguns experimentos que visam identificar o overhead inserido pelo ambiente ICE na execução das operaçõess do módulo de gerenciamento de aplicações, desenvolvido e descrito neste trabalho.

High-Resolution Multiscale Panoramic Mosaics from Pan-Tilt-Zoom Cameras. (2004)

We present an automatic software based approach for building extremely high resolution panoramic mosaics from images captured by an off-the-shelf pan tilt zoom camera. Using numerous zoomed-in images from such a camera, existing mosaicing algorithms could theoritically build gigapixel images. However the large number of images that must be processed makes such approaches impractical. Our stratified approach for high resolution panoramic imagery, first constructs a coarse panorama of the scene and then adds in detail from a zooming camera, in a top-down multiresolution fashion. Our approach uses both feature based and direct intensity based image alignment methods. Both the geometric calibration (intrinsic parameters and radial distortion) as well as the photometric calibration and alignment is done automatically. Our fully calibrated panoramas are represented as multi-resolution pyramids of cubemaps. We align hundreds of images captured within a 1-12X zoom range and show results from two datasets captured from cameras placed in an uncontrolled outdoor scene. 1.
