A hybrid system for navigation in GPS-challenged environments: case study (2008)

Reliable and continuous navigation in GPS-challenged environments is only possible with integrated systems that include self-contained sensors, which facilitate independent navigation during GPS outages. Traditionally, an inertial navigation system (INS) has been integrated with GPS to allow bridging during GPS gaps. The recently developed RF-based navigation and positioning system “Locata” offers an attractive augmentation alternative in situations where GPS satellite geometry is poor or the signal availability is limited. In cooperation with Locata Corporation, a Canberra-based company, School of Surveying and Spatial Information Systems (at the University of New South Wales - UNSW), and the Satellite Positioning and Inertial Navigation (SPIN) Laboratory (of The Ohio State University - OSU), have assembled a working prototype of a hybrid system based on GPS, inertial navigation and Locata receiver technology to provide seamless and reliable navigation to support vehicle guidance and control for mining, construction, mobile and GIS mapping, and industrial applications. For experimental purposes, a dual IMU system, based on the navigation grade H764G and a tactical grade CMIGITS2, were used. In addition, a Locata receiver and a dual-frequency GNSS receiver, the Leica System 1200, were used on a test vehicle at the Locata’s Numerella Test Facility, near Canberra, Australia. This test site features areas of both open sky as well as moderate to dense foliage. The test was repeated by mounting the devices on an autonomous electric car, operated on the UNSW campus. The GPS and Locata data were processed separately (for testing the internal consistency) as well in a hybrid solution, resulting in few centimetre-level accuracy for each coordinate component, depending primarily on GPS availability and the geometry between the test vehicle and the LocataLites, as well as the level of multipath.
A Two-Stage Switched-Capacitor Integrator for High Gain Inverter-Like Architectures (2019)

A discrete-time, switched capacitor integrator is presented. The integrator is based on a two-stage architecture where the first stage converts the input voltage into a charge that is accumulated into the second stage. The main strength of the proposed circuit is a higher dc gain with respect to previous solutions, making it optimal for low-voltage inverter-like integrators. A further advantage is the fact that, in contrast with existing solutions, the output voltage is valid across the whole clock cycle. Theoretical analysis of the circuit is performed to calculate the dependence of the integrator dc gain and input-referred offset voltage on the corresponding parameters of the constituting amplifiers. Discrete-time simulations are performed to estimate the gain and phase error with respect to an ideal integrator. The results of electrical simulations performed on an inverter-like prototype, designed with the UMC 0.18-μm CMOS process, are presented to show the impact of non-idealities from the amplifiers and switches.
Flash Flood Early Warning System in Colima, Mexico (2020)

This paper presents a system of sensors used in flash flood prediction that offers critical real-time information used to provide early warnings that can provide the minutes needed for persons to evacuate before imminent events. Flooding is one of the most serious natural disasters humans confront in terms of loss of life and results in long-term effects, which often have severely adverse social consequences. However, flash floods are potentially more dangerous to life because there is often little or no forewarning of the impending disaster. The Emergency Water Information Network (EWIN) offers a solution that integrates an early warning system, notifications, and real-time monitoring of flash flood risks. The platform has been implemented in Colima, Mexico covering the Colima and Villa de Alvarez metropolitan area. This platform consists of eight fixed riverside hydrological monitoring stations, eight meteorological stations, nomadic mobile monitoring stations called "drifters" used in the flow, and a sniffer with data muling capability. The results show that this platform effectively compiles and forwards information to decision-makers, government officials, and the general public, potentially providing valuable minutes for people to evacuate dangerous areas.
Purification and characterization of a novel β‐agarase from <i>Vibrio</i> sp. AP‐2 (1990)

beta-Agarase was purified from the culture fluid of a porphyran-decomposing marine bacterium (strain AP-2) by ammonium sulfate precipitation, successive column chromatography and DNase and RNase treatment. The final enzyme preparation appeared to be homogeneous on polyacrylamide gel electrophoresis. The enzyme had a molecular mass of 20 kDa, a pH optimum of 5.5, and was stable in the pH region 4.0-9.0 and at temperatures below 45 degrees C. The beta-agarase was a novel endo-type enzyme which hydrolyzed neoagarotetraose, larger neoagarooligosaccharides and agar to give neoagarobiose [3,6-anhydro-alpha-L-galactopyranosyl-(1----3)-D-galactose] as the predominant product. The enzyme did not act on kappa-carrageenan. According to the criteria of Bergey's Manual of Systematic Bacteriology, the strain was assigned to the genus Vibrio.
Krypton fluoride laser excited by high-power nanosecond microwave radiation (1988)

A lasing efficiency of 4% was achieved when an excimer laser utilizing an Ne–Kr–F2 mixture was pumped by a 200-MW nanosecond microwave pulse, the specific pump power being 1.4 MW/cm3. The absorption of the microwave energy in the active medium passed through a maximum at which the energy coupling efficiency approached 100%.
Microglial Dysregulation in Psychiatric Disease (2013)

Microglia, the brain's resident immune cells, are phagocytes of the macrophage lineage that have a key role in responding to inflammation and immune challenge in the brain. More recently, they have been shown to have a number of important roles beyond immune surveillance and response, including synaptic pruning during development and the support of adult neurogenesis. Microglial abnormalities have been found in several neuropsychiatric conditions, though in most cases it remains unclear whether these are causative or are a reaction to some other underlying pathophysiology. Here we summarize postmortem, animal, neuroimaging, and other evidence for microglial pathology in major depression, schizophrenia, autism, obsessive-compulsive disorder, and Tourette syndrome. We identify gaps in the existing literature and important areas for future research. If microglial pathology proves to be an important causative factor in these or other neuropsychiatric diseases, modulators of microglial function may represent a novel therapeutic strategy.
Dynamically Provisioning Cray DataWarp Storage (2019)

Complex applications and workflows needs are often exclusively expressed in terms of computational resources on HPC systems. In many cases, other resources like storage or network are not allocatable and are shared across the entire HPC system. By looking at the storage resource in particular, any workflow or application should be able to select both its preferred data manager and its required storage capability or capacity. To achieve such a goal, new mechanisms should be introduced. In this work, we introduce such a mechanism for dynamically provision a data management system on top of storage devices. We particularly focus our effort on deploying a BeeGFS instance across multiple DataWarp nodes on a Cray XC50 system. However, we also demonstrate that the same mechanism can be used to deploy BeeGFS on non-Cray system.
Correlation of nitrogen metabolism with biosurfactant production by Pseudomonas aeruginosa (1989)

A direct relationship between increased glutamine synthetase activity and enhanced biosurfactant production was found in Pseudomonas aeruginosa grown in nitrate and Proteose Peptone media. A chloramphenicol-tolerant strain showed a twofold increase in biosurfactant production and glutamine synthetase activity. Increased ammonium and glutamine concentrations repressed both phenomena.
Os/2 Presentation Manager Programming Primer (1990)

Programmers working with OS/2 can get up to speed fast on Presentation Manager, OS/2's graphical user interface. Text assumes no prior programming experience in OS/2--just knowledge of the C language.
Interleaving models for the analysis of twin shuttle automated storage and retrieval systems (2000)

A system of state equations is formulated for describing the dynamic behaviour of the queue of storage and retrieval transactions in a storage aisle served by twin shuttle storage and retrieval (S/R) machines. Using estimates of order picking cycle times in conjunction with storage and retrieval transaction demand levels, an estimate of the probability distribution of storage queue states is derived for a given storage aisle. System performance measures under an opportunistic interleaving discipline including S/R machine utilization, transaction queue lengths, average cycle times and expected transaction waiting times are approximated using the state probability distribution. The modelling tools are demonstrated using sample problems where the performance of twin versus single shuttle systems is contrasted for alternative combinations of storage and retrieval machine travel speeds, storage rack configurations, and transactions demand scenarios.
MR FLUIDS WITH NANO-SIZED MAGNETIC PARTICLES (1996)

Recently magnetorheological fluids with nanosized magnetic ferrite particles have become available. Their composition, rheological and magnetic properties are described. A comparison with conventional MR fluids based on micron-sized particles is given. The yield stress of nano-MR fluids can be increased by a moderate magnetic field (0,2 T) by 4000 Pa. It can be modulated by the magnetic field with a response time of less than 5 ms. Details are given on the long term thermal stability at 150 °C, on flow properties at elevated temperatures and at high shear rates. Design principles for MR fluid actuator design are outlined.
Practical Experiments with Regular Approximation of Context-Free Languages (2000)

Several methods are discussed that construct a finite automaton given a context-free grammar, including both methods that lead to subsets and those that lead to supersets of the original context-free language. Some of these methods of regular approximation are new, and some others are presented here in a more refined form with respect to existing literature. Practical experiments with the different methods of regular approximation are performed for spoken-language input: hypotheses from a speech recognizer are filtered through a finite automaton.
Large Displacement Stability by Design for Robust Aircraft Electric Power Systems (2012)

<div class="section abstract"><div class="htmlview paragraph">More electric aircraft (MEA) architectures have increased in complexity leading to a demand for evaluating the dynamic stability of their advanced electrical power systems (EPS). The system interactions found therein are amplified due to the increasingly integrated subsystems and on-demand power requirements of the EPS. Specifically, dynamic electrical loads with high peak-to-average power ratings as well as regenerative power capabilities have created a major challenge in design, control, and integration of the EPS and its components. Therefore, there exists a need to develop a theoretical framework that is feasible and useful for the specification and analysis of the stability of complex, multi-source, multi-load, reconfigurable EPS applicable to modern architectures.</div><div class="htmlview paragraph">This paper will review linear and nonlinear system stability analysis approaches applicable to a scalable representative EPS architecture with a focus on system stability evaluation during large-displacement events. Additionally, the paper will present a framework that expands recent work in large-displacement stability theory to enable practical stability analysis of multi-load, multi-source EPS architectures. This framework is based on reachable set control theory and evaluates the effects of bounded and potentially nonlinear system current injections without specific knowledge of the transient load profile of the EPS. Hence, it allows making quantitative statement of stability before detailed analysis in simulation and hardware.</div><div class="htmlview paragraph">Ultimately, the objective of this work is to develop a simple-to-use tool for analyzing EPS large displacement stability. This development will enable the system integrator to address practical challenges that commonly arise in the specification, design, and expansion of EPS architectures on airborne or other mobile platforms. Such challenges include determining how performance budgets can be allocated to the system during the initial design to enable independent supplier design without compromising a stable integrated system, analyzing possible load growth capability in a given EPS architecture, and identifying how an existing EPS could be modified, if necessary, to ensure system stability for a planned load growth with performance characteristics that cannot be modified.</div></div>
A case of lithium intoxication (1965)

LITHIuM, the lightest metal, has an atomic weight of seven and closely resembles sodium chemically. The ion is toxic and there are no therapeutic uses for lithium salts. Good (1903) quoted investigations of nearly twenty years previously in animals, where intravenous lithium salts depressed the heart's action and caused a fall in blood pressure. The dose of lithium salts necessary to stop the heart was found to be much larger than the dose of potassium salts necessary to produce the same effect. In 1948, lithium chloride was marketed in the U.S.A. as a salt substitute (Radomski, Fuyat, Nelson and Smith, 1950). The kidney, even in severe heart failure, excretes lithium much more readily than sodium, and therefore lithium does not promote water retention and oedema formation. This fact, plus the similarity in taste between lithium and sodium chlorides led to the use of lithium as a salt substitute (Drill, 1958). However, a number of patients died after receiving lithium and it is no longer used for this purpose. Lithium salts have been used in the treatment of mania (Lancet, 1955; Rice, 1956) and Kiloh, (1961) considered that in psychiatric practice the toxic effects of lithium salts are slight. Talbott (1950) found that symptoms of toxicity only occurred with serum lithium concentrations above 1 mEq./l. He found in a series of fourteen normal persons who ingested 1.56 g. of lithium carbonate daily for 5-14 days that the highest lithium concentration in the serum was 1.1 mEq. /1. In six persons gastrointestinal irritability was noted; correlation was observed between this symptom and the serum lithium. Three subjects experienced drowsiness. The mechanism whereby lithium produces its toxic effects is not clear although the principal action appears to be on the kidney.
Update on the ROAD Project and Lessons Learnt (2014)

The Rotterdam Opslag en Afvang Demonstratieproject (Rotterdam Storage and Capture Demonstration project), or ROAD, aims to build and operate a 250 MWe equivalent CCS chain using post-combustion capture technology and off-shore storage in a depleted gas field under the North Sea. The capture plant would be retrofitted to a new 1 070 MWe coal-fired unit (Maasvakte Power Plant 3) in Rotterdam, Netherlands. It was originally intended to reach a final investment decision at the end of 2010, but the project has faced a series delay associated with permitting, complex commercial negotiations and, most seriously, funding. At the moment (September 2014), the European Commission and the Government of the Netherlands are engaged in a renewed push to solve the funding problems and allow construction to finally start. The project has financial support from the European Energy Programme for Recovery (EEPR) and the Government of the Netherlands and is now the only one of the six projects originally supported that still has any realistic prospect of being realized in the short term. This paper presents an update of the overall project development as at the time of GHGT-12 and the accomplished milestones and issues met in the permitting process. In addition, it will focus on the technical and economic aspects of integrating the capture plant with the power plant. Furthermore, it will provide an outlook on future CCS/CCU developments in Rotterdam, describing the steps under development to create a full CO2 hub in the port including options for ship transport and bio-CCS. The paper concludes with the management of the project delays and the implications for the project economics.
Just-in-time information sharing architectures in multiagent systems (2002)

ACORN (Agent-based Community Oriented Routing Network) is a distributed multi-agent architecture for the search, distribution and management of information across networks. ACORN utilises the concept of 'information as agent' together with an application of Stanley Milgram's Small World Problem (the idea of the Six Degrees of Separation) in order to route individual items of information around a network of people and agents. This paper describes additions made to the ACORN architecture and the implementation. A directory server that facilitates real-time communication between a client and corresponding agent is implemented. This server allows for instant feedback and modification to the agent by the client. The concept of an anonymous service provider is introduced to allow clients to generate anonymous agents that cannot be traced back to the original creator of the agent. This service is vital for maintaining some privacy aspects of the user. ACORN consists of a set of information-sharing locations referred to as Cafés. A dynamic café clustering method is developed. Using the proposed clustering method, cafés are dynamically created / destroyed to most accurately reflect the collective interests of the given members of said café. The performance evaluation of the proposed structure for the café using a testbed of multiple virtual users shows that the addition of multi-café component to ACORN's architecture improves its information sharing efficiency and leads to significant reduction in unnecessary mingling. Lastly, the concept of a fat and thin agent is introduced. A fat/thin agent architecture allows for minimizing network traffic as agents traverse the network in search of or distribution of knowledge.
Effects of gender information in text-independent and text-dependent speaker verification (2017)

It is well-known that for speaker recognition task, gender-dependent acoustic modeling performs better than gender-independent modeling. The practice is to use the gender ground-truth and to train gender-dependent models. However, such information is not necessarily available, especially if speakers are remotely enrolled. A way to overcome this is to use a gender classification system, which introduces an additional layer of uncertainty. To date, such uncertainty has not been studied. We implement two gender classifier systems and test them with two different corpora and speaker verification systems. We find that estimated gender information can improve speaker verification accuracy over gender-independent methods. Our detailed analysis suggests that gender estimation should have a sufficiently high accuracy to yield improvements in speaker verification performance.
Plasma etching of thick polynorbornene layers for electronic packaging applications (2002)

The etch characteristics of thick (&gt;20 μm) polynorbornene films used as insulators in chip-to-board interconnection structures were studied in O2/CHF3-based plasmas. Two polynorbornene materials were investigated in this study: one with an epoxy substituent and the other with a silicon substituent. The effects of processing parameters such as radio-frequency (rf) power, chamber pressure, flow rate, gas composition, and mask material on polymer etch rate and via sidewall angle were investigated. The etch rate increased with rf power and chamber pressure. An increase in the CHF3/O2 ratio gave a maximum etch rate at ∼10% CHF3 for the epoxy-containing polynorbornene and at ∼20% CHF3 for the Si-containing polynorbornene. The etch rate decreased with total flow rate in O2/CHF3 plasmas but did not change substantially with flow rate in O2 plasmas. The sidewall angle was strongly affected by rf power and chamber pressure.
An EREW PRAM algorithm for image component labeling (1989)

An important midlevel task for computer vision is addressed. The problem consists of labeling connected components in N/sup 1/2/*N/sup 2/2/ binary images. This task can be solved with parallel computers by using a simple and novel algorithm. The parallel computing model used is a synchronous fine-grained shared-memory model where only one processor can read from or write to the same memory location at a given time. This model is known as the exclusive-read exclusive-write parallel RAM (EREW PRAM). Using this model, the algorithm presented has O(log N) complexity. The algorithm can run on parallel machines other than the EREW PRAM. In particular, it offers an optimal image component labeling algorithm for mesh-connected computers.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Pulsed laser deposition of graphite counter electrodes for dye-sensitized solar cells (2010)

We report on pulsed laser deposition of graphite onto flexible plastic and conductive glass substrates for use as a counter electrode in dye-sensitized solar cells. The efficiency of as-prepared graphite electrodes was tested using CdS-sensitized solar cell architecture resulting in external quantum efficiency comparable to that of conventional platinum counter electrodes. This work highlights the possibility of using pulsed laser deposited graphite as a low-cost alternative to platinum, which could be fabricated both on flexible and rigid substrates.
