State Observer-Based Sensor Fault Detection and Isolation, and Fault Tolerant Control of a Single-Phase PWM Rectifier for Electric Railway Traction (2013)

This paper presents an easy and a robust sensor fault detection and isolation (FDI) and fault tolerant control (FTC) of a single phase PWM rectifier for electrical railway traction application. Catenary current sensor and dc link voltage sensor failures are considered. The FDI method is based on observers and residual generation. The different FDI algorithm steps allow a good detection and isolation of the sensor fault and identify the faulty sensor. The reconfiguration strategy consists of two steps with open loop control and closed loop control working. Simulation results are presented to illustrate the good performance of the FTC procedure. Experimental results are also presented to show the effectiveness of the proposed FDI and FTC algorithms and good performances of the rectifier after the reconfiguration.

Structure and Dynamics of Carbon Nanoscrolls (2004)

Carbon nanotube scrolls (CNSs) provide an interesting form of carbon that ideally consists of a single sheet of graphite that is spiral wrapped to form a nanotube. We here use molecular dynamics simulations to investigate CNS formation, stability, and the structural effects due to charge injection. CNS formation is seen to automatically occur when a critical overlap between sheet layers is achieved for the partially curled sheet. We find that charge injection causes unwinding of the CNSs, which might be important for the application of CNSs as nanomechanical actuators.
Modified channel shortening receiver based on MSSNR algorithm for UWB channels (2007)

A modified version of the maximum shortening signal-to-noise ratio (MSSNR) algorithm for channel shortening in ultra-wideband (UWB) communication systems is presented. The proposed algorithm introduces two additional UWB channel related parameters in the optimisation problem along with the conventional energy criterion. This modification significantly improves the performance of the conventional MSSNR algorithm and enables it to handle the extreme nature of channel shortening needed in UWB systems. The proposed algorithm outperforms the conventional MSSNR algorithm in terms of different comparative parameters.
Colloidal Ellipsoids with Continuously Variable Shape (2000)

Oblate and prolate ellipsoidal inorganic colloids can be synthesized by combining colloidal chemistry and ion irradiation techniques, as reported here. It is found that dramatic anisotropic plastic deformation of monodisperse silica and zinc sulfide microspheres occurs under 4 MeV Xe ion irradiation (see Figure). Possible application in the assembly of liquid crystals is demonstrated.
Transthyretin Receptors on Human Astrocytoma Cells* (1990)

Transthyretin (TTR), a transport protein for T4 and retinol-binding protein, is the principal T4-binding protein of cerebrospinal fluid. Its function in regard to the delivery of its ligands and in other respects is unclear. The binding of [125I] TTR to cultured human astrocytoma cells was studied to determine whether these cells carry receptors for TTR. Scatchard analysis was consistent with a single class of binding sites with a Kd of 3 nM. No significant cross-reactivity with transferrin or serum albumin was observed. Internalization of TTR was temperature dependent and proportional to receptor occupancy. Dilutions of cerebrospinal fluid displaced [125I]TTR in proportion to their content of radioimmunoassayable TTR and in parallel with purified TTR. The uptake and internalization of TTR increased in the presence of high T4 or T3 concentrations. These results demonstrate that TTR binds to specific high affinity receptors on human astrocytoma cells. Receptor binding of TTR provides a potential mechanism for the delivery of its ligands within the central nervous system.
Joint Placement of Phasor and Power Flow Measurements for Observability of Power Systems (2011)

We consider the problem of joint optimal placement of phasor measurement units (PMU) and conventional measurements to ensure full observability in power systems. The formulation is initially posed as a nonlinear integer programming problem and then transformed in to an equivalent integer linear programming (ILP) problem by introducing auxiliary variables and constraints. The resulting ILP problem is solved for the optimal solution on IEEE 14-, 57-, and 118-bus systems considering zero-injection buses. To extend the formulation to large-scale systems, two heuristics are proposed where the nonlinear problem is decomposed into two separate problems of lesser complexity. The heuristics are evaluated on standard IEEE test cases and a large 2383-bus Polish system. The heuristics yield solutions close to optimal (difference of 1 PMU) solutions on standard IEEE systems, while substantially reducing problem complexity and run time. The placement results obtained with the proposed formulation require fewer PMUs for observability compared to systems with fixed locations of conventional measurements. The results thus potentially provide a more economical solution to system observability compared to those obtained solely with PMU placement.
Fusion of Mobile In situ and Satellite Remote Sensing Observations of Chemical Release Emissions to Improve Disaster Response (2016)

Chemical release disasters have serious consequences, disrupting ecosystems, society, and causing significant loss of life. Mitigating the destructive impacts relies on identification and mapping, monitoring, and trajectory forecasting. Improvements in sensor capabilities are enabling airborne and spacebased remote sensing to support response activities. Key applications are improving transport models in complex terrain and improved disaster response.

Mitigating the destructive impacts relies on identification and mapping, monitoring, and trajectory forecasting. Improvements in sensor capabilities are enabling airborne and space-based remote sensing to support response activities. Key applications are improving transport models in complex terrain and improved disaster response. Understanding urban atmospheric transport in the Los Angeles Basin, where topographic influences on transport patterns are significant, was improved by leveraging the Aliso Canyon leak as an atmospheric tracer. Plume characterization data was collected by the AutoMObile trace Gas (AMOG) Surveyor, a commuter car modified for science. Mobile surface in situ CH4 and winds were measured by AMOG Surveyor under Santa Ana conditions to estimate an emission rate of 365±30% Gg yr-1. Vertical profiles were collected by AMOG Surveyor by leveraging local topography for vertical profiling to identify the planetary boundary layer at ~700 m. Topography significantly constrained plume dispersion by up to a factor of two. The observed plume trajectory was used to validate satellite aerosol optical depth-inferred atmospheric transport, which suggested the plume first was driven offshore, but then veered back towards land. Numerical long-range transport model predictions confirm this interpretation. This study demonstrated a novel application of satellite aerosol remote sensing for disaster response.
CERKLMutations Cause an Autosomal Recessive Cone-Rod Dystrophy with Inner Retinopathy (2009)

CERKL mutations are associated with widespread retinal degeneration with prominent maculopathy. The clinical presentation is that of an autosomal recessive cone-rod dystrophy. Photoreceptor loss appears at all stages of disease and inner laminopathy complicates the phenotype at later stages.
Reusable Homogeneous Catalytic System for Hydrogen Production from Methanol and Water (2014)

An efficient system catalyzed by a Ru-PNN pincer complex was developed for reforming methanol to H2 and CO2 (absorbed by base) under relatively low temperature (around 100 °C), and good yields of H2 were obtained (∼80%). The catalyst solution can be reused without isolation and purification, with no decrease in catalytic activity being observed for a period of ∼1 month. Decomposition of formic acid, which is likely to be the last step of the methanol reforming reaction, was also investigated, and the formic acid adduct of the catalyst was fully characterized spectroscopically and by X-ray crystallography.

Tree Image Growth Analysis Using Instantaneous Phase Modulation (2011)

We propose the use of Amplitude-Modulation Frequency-Modulation (AM-FM) methods for tree growth analysis. Tree growth is modeled using phase modulation. For adapting AM-FM methods to different images, we introduce the use of fast filterbank filter coefficient computation based on piecewise linear polynomials and radial frequency magnitude estimation using integer-based Savitzky-Golay filters for derivative estimation. For a wide range of images, a simple filterbank design with only 4 channel filters is used. Filterbank specification is based on two different methods. For each input image, the FM image is estimated using dominant component analysis. A tree growth model is developed to characterize and depict quarterly and half-seasonal growth of trees using instantaneous phase. Qualitative evaluation of inter- and intraring reconstruction is performed on 20 aspen images and a mixture of 12 tree images of various types. Qualitative scores indicate that the results were mostly of good to excellent quality (4.4/5.0 and 4.0/5.0 for the two databases, resp.).
Identity management (2003)

The true value of identity management comes into play with business partners and consumers. The ability to federate identity across organizations while maintaining clear trust, liability, and cost responsibilities is a major challenge for enterprises as we continue to pursue efficiency and cost savings in cross-organizational business and customer-relationship processes.
Analysis of GIDL Dependence on STI-induced Mechanical Stress (2006)

The mechanical stress induced by shallow trench isolation (STI) signifilcantly affects the device behavior in the advanced CMOS technology. This paper presents an STI-dependent gate-induced drain leakage (GIDL) model and investigates the physical mechanisms in this phenomenon. Our simulation indicates that STI-induced compressive stress causes energy band gap narrowing. As a consequence, the effective tunneling barrier height becomes lower and intrinsic carrier concentration increases. These two factors enhance band-to-band tunneling (BBT) and trap-assisted tunneling (TAT), respectively. And an asymmetric layout is proposed to reduce the GIDL current.
Global Warming Control to Mitigate Climate Change (2012)

Aim is to enable establishment and comparison of the collective effects of global determinants on global warming in the prescription of the regulations most fit for the collective deployment in each of the determinant countries to enable mitigation of the greenhouse gases build-up caused global warming.
Cooperative Effects in Water Binding to Cuprous Oxide Surfaces (2015)

Water adsorption on solid surfaces plays a part in a variety of processes, including renewable energy applications. Water adsorption can occur either dissociatively, monomolecularly, or as clusters. In contrast to metal surfaces, the compositional and structural complexity of metal oxide surfaces has inhibited atomic-scale understanding of their interactions with water. Cu2O is a promising photocatalyst and (photo)electrochemical catalyst. Here, we investigate water adsorption on its (111) surface, using density functional theory + U with dispersion corrections. A number of monomolecular and dissociated adsorbate geometries are considered on the two most stable surface terminations. H2O is found to adsorb most strongly when datively coordinated to an unsaturated surface Cu cation; dissociative adsorption is not as favorable as this dative bonding mode of molecular chemisorption. If these Cu cations are not present, H2O binds via hydrogen bonding and electrostatic interactions in surface cavities. We also examine a large variety of mixed modes of coadsorption. Mixtures of datively bonded and hydrogen-bonded water molecules adsorb most strongly, exhibiting a strong lateral interaction. The resulting water clusters can adapt to the underlying adsorption site template and maintain significant water–surface and water–water interactions at the same time. This is possible through the proximity of the unsaturated cationic and anionic adsorption sites. The combination of dative and hydrogen bonding to the surface enables water clustering even at low temperatures, probably due to rapid surface diffusion of the more weakly bonded monomers. The strong dative and lateral interactions keep water clusters adsorbed up to unusually high temperatures. The water hexamer can still be observed at room temperature under ultrahigh vacuum conditions; we predict that datively bound monomers, hexamers, and other similarly constructed clusters will remain bound to the stoichiometric surface up to quite high temperatures under conditions of high relative humidity. We suggest that metal oxides with similar surface compositions should show similar properties. Finally, we predict vibrational frequencies for the adsorbed water molecules and distinguish between water–water and water–surface vibrations for comparison with future experimental studies.

Memories, Monuments, Histories: The Re-thinking of the Second World War since 1989 (2006)

On 17 June 1940, during the period of the Nazi-Soviet Pact, Latvia was invaded by the Red Army and annexed as part of the Soviet Union. Then, just one year later, the country was invaded by Nazi Germany and subjected to a four-year occupation before being invaded by the USSR. Thereafter the country remained part of the Soviet Union until the break up of the latter in August 1991. Taking Latvia as a starting point, this article will explore how the memory of the Second World War has been re-located since the demise of the communist regimes in Eastern Europe between 1989 and 1991. In doing so, it will be argued that the period since the end of the Cold War has produced a thorough reappraisal of the significance of the years 1939 to 1945 not just in terms of the academic history profession, but also wider processes of remembrance operating at the level of the nation-state commemorations, the European Union, the heritage industry, education and personal memories.
The Galileo Ground Segment Reference Receiver Development: Architecture and Critical Design Issues (2003)

The challenging schedule of the Galileo development requires starting design of user and reference receivers as early as possible. LABEN (a Finmeccanica Company) is leading a consortium that is in charge of a pre-development study for the Galileo Ground Mission Segment Reference Receiver, under ESA contract. The main objective of the pre-development study is to define the receiver specifications and to define the preliminary architecture of the receiver including RF/IF, digital and software sections. The pre-development activity will be completed with analysis and simulation of the critical design issues in order to consolidate the specifications and architectural choices. The receiver specification and architecture will form the basis of subsequent detailed design cycles. The receiver design is supported by the development of a modular SW simulator, which allows investigation and trade-off between different design schemes and algorithms for BOC signals acquisition and tracking and for Navigation & Time solutions. The paper provides an overall description of the receiver design and focuses on the main choices and critical characteristics for the processing of the Galileo signals. It presents an overview of the simulation SW and discusses some preliminary performance results in terms of signal acquisition and tracking.
Crystallography of carbide precipitation at transformation interfaces during austenite decomposition in a low-alloy steel (1987)

An examination by transmission electron microscopy has been made of the austenite → ferrite + carbide reaction in an Fe–C–V low-alloy steel over the transformation temperature range 550–850°C. Thin films of interlath retained austenite in the untransformed martensite regions of partially transformed specimens have been used to investigate the crystallographic relationships between parent and product phases. Grain boundary ferrite allotriomorphs nucleate with a rational orientation relationship to at least one, but also occasionally to both, of the two adjacent austenite grains. Interphase precipitation of vanadium carbide can occur in the ferrite irrespective of the austenite–ferrite crystallographic relationship and, in particular, it is shown that the single habit plane adopted by the carbide is not a consequence of a three-phase crystallographic relationship between parent austenite and the product ferrite and carbide phases. It is thought that the precipitate adopts that habit plane which lies at the smallest angle to the plane of the transformation interface, and additional experimental evidence to support this is presented.MST/664
Response of Black African patients with hepatitis C virus genotype 4 to treatment with peg-interferon and ribavirin. (2013)

In our cohort, treatment-naive BA patients with HCV-4 who were treated with peg-IFN and ribavirin had a much lower SVR rate than treatment-naive non-BA patients with HCV-4 who were treated with peg-IFN and ribavirin, and a higher relapse rate, possibly related to a weaker response to interferon-based therapy. Treatment may need to be adapted in this population.
A New Type of Optical Range Sensing Method for Surface Tracing (1986)

Anew type of optical range sensing method suitable for surface tracing ( RORST : Riken Optical Range Sensing Method for Surface Tracing ) has been developped. An axial symmetrical cylindrical or circular conical ) light sheet is projected on to an object; a ring pattern is produced on the surface of an object; the ring pattern image is projected on to an observation plane by an objective lens; radii of the ring pattern image on the observation plane for different azimuths are detected; distances corresponding to the specified azimuths are determined by the principle of triangulation; thus the information of partial inclination can be obtained. Basic experiments have been perfomed and it has been proved that the proposed method can provide a compact optical range sensor which can detect not only the distance but also the partial inclination of a surface.
Fine paper pH control using carbon dioxide (2012)

Maryvale No.5 paper machine (M5) is a fine paper machine manufacturing office papers, predominantly the 'Reflex' brand, for the Australian Market. Originally the machine was rated 180,000tpa and has just been upgraded so that it now produces 220,000tpa. The majority of the pulp furnish is supplied from a recently installed onsite bleach plant. M5 also manufactures office paper from recycled pulp. Variations caused by poor pH control have led to variable performance on the paper machine. A trial of the Linde (BOC) technology using carbon dioxide to lower and control the pH to a set value was commenced in May 2010. It has proved to be successful and has led to a permanent installation.
An MDDI-Host Architecture with Low Complexity for SoC Platforms (2007)

This paper proposes a low-complexity mobile display digital interface (MDDI) architecture. We implement and verify the proposed MDDI-host architecture on a system-on-chip (SoC) platform with a 32-bit RISC CPU and a FPGA module. As a result of verification, the gate count of the MDDI host is reduced by about 50 % compared to that of the conventional parallel interface. And the bandwidth per pin of the MDDI host is 3 times more than that of a conventional parallel interface. Furthermore, the MDDI host that we implement includes the advanced high-performance bus (AHB) interface. Therefore, the proposed MDDI architecture is suitable for SoC platforms .
