Virtual reality-new methods for improving and accelerating the development process in vehicle styling and design (2002)

The article describes the use of virtual reality techniques during the car development process at Volkswagen. A brief definition of virtual reality is given and it is pointed out that virtual reality has to be understood as a method and not only as a tool. There is a short introduction of the research topics that are investigated by the VR-Lab. Some of them are presented in more detail. It is shown which steps have to be taken to get a virtual reality design review model. The problems are pointed out and possible solutions are described. An interface to the 3D human model, RAMSIS, has been implemented. RAMSIS is the result of a joint venture of German car companies and two seat manufacturers. The goal of implementing RAMSIS was to generate a realistic simulation of human beings in car interiors and work places. The integration of the CAD geometry kernel, ACIS, enhances the analytical possibilities of the virtual reality system by adding the same parametric surfaces used by the original CAD system and providing a wide variety of CAD functionality (e.g. cutting planes, distance measuring, Boolean operations). A 3D interaction model for modifying colors and surface structures of car interiors provides an easy and intuitive access to the geometric models concerned. Arbitrary components can be selected freely within the virtual environment and they can be manipulated "by a wave" of the hand.
Special Feature. Predicting time series by a fully connected neural network trained by back propagation (1992)

This article describes privately funded work carried out by SD-Scicon UK Ltd. on the use of neural networks for time series prediction. The advantages of a neural approach are discussed, and some possible back propagation architectures described. Detailed evaluation is made of one particular architecture, based on a fully connected recurrent network. The network has been evaluated for both deterministically and stochastically generated time series, as well as real process data. Results are presented for the latter, and comparisons made with the performance achieved by a bespoke Kalman filter. The article also discusses the use of a ‘spread encoding’ scheme for representing input and output data, which enables the network to learn local linearisations on the input data and allows for probabilistic interpretation of the output data.
Abdominal aortic occlusion: a rare complication of cardiac myxoma. (2001)

Myxomas, which are benign tumors, are typically pedunculated and highly mobile, passing in and out of the atrioventricular valves. Their mobility, gelatinous consistency, and friable surfaces enhance their embolic potential. In most cases of embolization, the emboli obstruct the cerebral arteries; occasionally, the visceral or coronary arteries are blocked. Tumor emboli rarely cause abdominal aortic occlusion or a saddle embolus. 1,2

A 79-year-old man was admitted to our institution with an acute episode of abdominal pain followed by weakness in both legs. At the clinical examination, bilateral femoral pulses were absent; paralysis and anesthesia of both legs were also noted. A computed tomographic scan of the abdomen showed what appeared to be embolic occlusion of the abdominal aorta at the L4 level (Fig. 1). The patient underwent catheter embolectomy via a bilateral femoral approach. The retrieved materials were found to be tumor emboli (Fig. 2), which in turn were shown, by means of a histologic examination, to be from a cardiac myxoma. Immediately after the procedure, the patient's pain resolved, and he regained normal muscle strength in his lower extremities. Transthoracic echocardiography then revealed a left atrial myxoma (Fig. 3). The patient underwent tumor excision under cardiopulmonary bypass on the following day. The postoperative course was uneventful, and he was discharged 7 days after the operation.

The clinical presentation of our case was very similar to that of a previous report by Horn and colleagues, 2 but our patient made a complete recovery. Our case emphasizes that, because peripheral embolization of a cardiac myxoma is a common sequela, any embolectomy specimen should be examined carefully for gross and histologic evidence of myxomatous character. Transthoracic echocardiography is the best diagnostic technique. Once it was discovered in our patient, the left atrial myxoma was excised with the patient under cardiopulmonary bypass, thus removing the risk of further embolic complications. 1
Zero-Shot Recognition Using Dual Visual-Semantic Mapping Paths (2017)

Zero-shot recognition aims to accurately recognize objects of unseen classes by using a shared visual-semantic mapping between the image feature space and the semantic embedding space. This mapping is learned on training data of seen classes and is expected to have transfer ability to unseen classes. In this paper, we tackle this problem by exploiting the intrinsic relationship between the semantic space manifold and the transfer ability of visual-semantic mapping. We formalize their connection and cast zero-shot recognition as a joint optimization problem. Motivated by this, we propose a novel framework for zero-shot recognition, which contains dual visual-semantic mapping paths. Our analysis shows this framework can not only apply prior semantic knowledge to infer underlying semantic manifold in the image feature space, but also generate optimized semantic embedding space, which can enhance the transfer ability of the visual-semantic mapping to unseen classes. The proposed method is evaluated for zero-shot recognition on four benchmark datasets, achieving outstanding results.
Phonon density of states of silicon clathrates: Characteristic width narrowing effect with respect to the diamond phase (1999)

The phonon density of states of different silicon clathrate phases is measured by inelastic neutron scattering. ${M}_{x}@\mathrm{S}\mathrm{i}\ensuremath{-}34$ and ${M}_{x}@\mathrm{S}\mathrm{i}\ensuremath{-}46$ clathrates with different alkaline $(M=\mathrm{N}\mathrm{a},\mathrm{}\mathrm{K})$ and composition x are investigated. A width-narrowing effect is observed on the phonon spectra with respect to the diamond silicon structure. The effect of the alkali atom-silicon atom coupling is seen demonstrating the strong interaction between the alkali- atom and the host silicon cage. Such specific properties of clathrate lattices are interpreted in term of local icosahedral symmetry.
Radioimmunoassay for measurement of bovine α-lactalbumin in serum, milk and tissue culture media (1986)

A sensitive, specific radioimmunoassay for bovine alpha-lactalbumin (alpha-la) suitable for measurement of serum, tissue culture media and milk was developed. alpha-La was not detected in serum from prepubertal male or female cattle, but was detected as early as 60 d of gestation in nulliparous Holstein heifers, the level being greatly increased during the last one third of gestation. Serum from cross bred beef heifers contained less alpha-la and it was not detected until late gestation. Concentrations of alpha-la in serum samples from pregnant multiparous Holstein cows decreased at drying-off and subsequently increased just before parturition. Secretion of alpha-la by mammary tissue explants from steroid-primed prepubertal Holstein heifers was induced by the addition of bovine prolactin, ovine prolactin or human growth hormone to tissue culture media.
In vivo Performance of Biodegradable Calcium Phosphate Glass Ceramics using the Rabbit Model: Histological and SEM Observation (2005)

Two MK5 (45CaO-45P(2)O(5)-5MgO-5K(2)O, in mol%) and MT13 (45CaO-37P(2)O(5)-5MgO-13TiO(2), in mol%) glasses are prepared in the meta- and pyrophosphate regions and crystallized to obtain MK5B and MT13B, respectively. MK5B was obtained by controlled crystallization, and MT13B by powder sintering. As a result of these heat treatment processes, the crystalline phases precipitated in the glassy matrix are KCa(PO(3))(3), beta-Ca(PO(3))(2), beta-Ca(2)P(2)O(7) and Ca(4)P(6)O(19) phases for MK5B and CaTi(4)(PO(4))(6), TiP(2)O(7), alpha- and beta-Ca(2)P(2)O(7) phases for MT13B. To assess the in vivo biological behavior of these glass ceramics, a mixed granulometry in the range 250-355 mum and 355-425 mum with a ratio of 1/1 was implanted for 2, 4, and 12 weeks in the tibiae of Japanese white rabbits. The results showed that the in vivo behavior was strongly affected by their solubility. All implanted materials, MK5B and MT13B, and beta-tricalcium phosphate (beta-TCP) as control material, showed signs of degradation in vivo. However, the levels of degradation were quite different throughout the implantation periods. The highest degradation was observed for MK5B glass ceramic and the lowest for MT13B with beta-TCP in-between. All implanted materials allow for new bone formation in the bone defect area. At the longest implantation period (12 weeks), the MT13B and beta-TCP materials were almost completely surrounded by new bone tissue, whereas MK5B showed some unfilled spaces. This behavior is discussed in terms of the high degradation observed in previous studies.
A systems approach to verification using hardware acceleration (2010)

The increasing complexity of system-on-chip devices has made verification of these devices an extremely difficult task. Additionally, there is the pressure of time-to-market that is faced by all semiconductor companies. Some of the functional complexity of such devices has made it necessary to run system level sequences that were typically run only in post-silicon phase in the pre-silicon stages. However, the effective speeds of simulators used during functional verification do not lend well to running system level tests. In this paper we will describe how a hardware accelerator was used to execute system level tests. We will share some of the results seen and some of the design issues that were detected using such an approach. We have illustrated this approach choosing three distinct areas of (i) secure boot, (ii) built-in-self-test sequences, and (iii) scan testing. We also believe that going to a system level approach using hardware acceleration helps to find several difficult corner case issues that remain undetected using other verification approaches.
Composite-structure frequency selective surface with tripole elements (2008)

Two composite symmetry structure is proposed in this paper. Based on the integral equation method, the frequency response with large incident angle effect is analyzed. As a result of the numerical analysis, it is shown that the composite symmetry structure with single FSS screen is efficient to stabilize the drift of FSS resonant frequency with the steering of incident angle though transmission loss increased. Especially the structure that the FSS is embedded centrally in the dielectrics has better frequency characteristic with flat top and sharp skirts. The studies have indicated the versatility of the proposed structure.
PROPOSAL TO DESIGNATE STRAIN ATCC 3004 (IMRU 3004) AS THE NEOTYPE STRAIN OF <i>STREPTOMYCES ALBUS</i> (ROSSI-DORIA) WAKSMAN AND HENRICI (1962)

Lyons, A. J., Jr. (Northern Regional Research Laboratory, Peoria, Ill.) and T. G. Pridham. Proposal to designate strain ATCC 3004 (IMRU 3004) as the neotype strain of Streptomyces albus (Rossi-Doria) Waksman and Henrici. J. Bacteriol. 83:370-380. 1962.-It is proposed that strain ATCC 3004 (IMRU 3004) be designated henceforth as the neotype strain of Streptomyces albus (Rossi-Doria) Waksman and Henrici and as the type strain of the genus Streptomyces Waksman and Henrici. The proposal is based not only on the fact that the holotype strain [Streptotrix (sic) alba] of Rossi-Doria is no longer extant, but also on the fact that a study of the literature and a taxonomic study of 55 strains of the organism indicate the species should exhibit these characteristics: catenulate ovoidal spores, white aerial mycelium, coiled sporophores, proteolytic activity, and nonchromogenicity (inability to form brown, deep brown, or black diffusible pigments). Strain ATCC 3004 (IMRU 3004) exhibits these characteristics, as do 16 other acquisitions. Study of the 16 additional strains that conform with the general definition of the species shows differences in some physiological characteristics. It is suggested that these differences are of subspecific significance.
Effects of waterbolus size, shape and configuration on the SAR distribution pattern of the Lucite cone applicator (2006)

The effects of waterbolus dimensions and configuration on the effective field size (EFS) of the Lucite cone applicator (LCA) for superficial hyperthermia are presented. The goal of the research is to develop guidelines which mark out a sub-set of optimal LCA-waterbolus set-ups. The effects of variations in (i) waterbolus thickness, (ii) waterbolus area, (iii) waterbolus length/width ratio and (iv) eccentric placement of the applicator have been investigated in an FDTD model study. The prominent effects are verified with IR thermography measurements. An optimal EFS value of 80 cm2 is found for waterbolus area of 200-400 cm2. A small (10 x 10 cm2) waterbolus area restricts the EFS to 25% of the optimal value. The sensitivity to sub-optimal waterbolus area and length/width ratio increases with waterbolus height. Eccentric placement of the LCA near the waterbolus edge reduces the EFS to up to 50% of the optimal value. The IR measurements confirm the model findings. Based on the results, the following guidelines for the clinical application of the LCA have been defined: the waterbolus (i) should extend the LCA aperture at least 2.5 cm, especially at the Lucite windows, and (ii) the height should not exceed 2 cm.
Techniques of visualization for distribution automation system (2008)

Distribution automation system supervises and manages all the loads, equipments and faults in the area of distribution. Due to a vast area , too many equipments and complex circumstance, the traditional display method can't satisfy the demand of modern distribution automation system. In the traditional distribution automation system we often use one-line diagram, geography diagram, curve drawing and bar chart to display the state of distribution automation system, they're too simple to display the complex and large scale diagrams. It need to be introduced into new techniques to supervise, control and display the running state of distribution automation system. The visualization technique is a new project practical technique which appears along with the computer graphics development in 1990s. It transforms each kind of complex project data as the direct-viewing graph. It's advantageous to people to have a thorough grasp and a correct understanding of the facts. This paper introduces the graph visualization technique, discusses the application of visualization technique in the distribution automation system. In order to analyze data, dig up the connections between data and select suitable method to display, the paper provides a new thinking. The paper introduces all kinds of method of visualization graph, such as: 2D, 3D graph, contour line, gradual change area coloring, pie chart, arrowhead, direction, speed, varying size and so on. It describes the method to realize these techniques. The new techniques include: three-dimensional graph technique based on openGL, cartoon technique, the algorithm of contouring, the algorithm of area drawing. The research indicates that it is inefficient to simply display the system data that isn't processed. The visualized vivid graph may express the information which need many data to indicate. Our visualization software not only expresses the system with the visualization graph method, but also carries on the analysis and the excavation in the system magnanimous data. It discovers intrinsic relation of the data to reflect the system mode accurately and displays them by the suitable visualization method. The information expressed in the distribution automation system is: state, capacity, margin, phase angle, speed, load distribution, movement tendency, stable region, geographic distribution information and so on. The display of the information is not isolated. It may simultaneously express many kinds of data meaning through one visualization method. Certainly, the time which the visualization technique is used in our country is not very long. Many companies use the overseas software directly. There are few companies to develop their own real-time application visualization software. Our company makes great progress in the research into computer graph technique and applying visualization technique in the real-time distribution automation system. We also have obtained the quite good effect. Along with the scale of our power system unceasing expansion, higher request, the visualization technique must be obtained broad application.
Schedulability Analysis and GCL Computation for Time-Sensitive Networks (2019)

Industrial automation networks are composed of cyber-physical systems where frame delays and jitter influence significantly the quality of communication between control and field devices. Due to these constraints, such systems are often served by dedicated Fieldbus networks which are different from networks for enterprise-level connectivity. However, with the introduction of Time-sensitive Networking standards which are already integrated into IEEE 802.1Q-2018 standards in essential parts, the long expected single converged network for any-type communication in the field, control, and enterprise level is within reach. With it, comes the challenge of synthesizing schedules to obtain parameters for configuring the network bridges for time-triggered communication services.This paper provides a scheduling verification, and Gate Control event computation algorithm focused on asserting the viability of scheduling communication services for multiple independent periodic Talker applications on IEEE 802.1Q- Time Sensitive Networks as well as the computation of Gate Control Lists for the bridges.
Experimental Investigation of Chemical-Looping Combustion in Packed Beds: A Parametric Study (2011)

Recently a novel reactor concept for chemical-looping combustion (CLC) has been proposed exploiting dynamically operated packed beds. In this work, an experimental parametric study on this reactor concept has been carried out. The effects of operating temperature, feed oxygen concentration, steam addition, and type of oxygen carrier material (CuO/Al2O3 and CaMnO3) have been evaluated. It has been found that an increase of the reduction temperature resulted in a higher conversion of the oxygen carrier, increased reduction reaction rates, and increasing significance of various side-reactions. Steam addition suppresses carbon deposition on the oxygen carrier. Interesting insights in the relevance of steam reforming and water−gas shift during the reduction cycle were obtained. Finally, CaMnO3 is of interest for CLC in packed beds in view of the high oxygen capacity of the material and the excellent selectivity to the formation of CO2.
Thermodynamic properties and dielectric constants in water/methanol mixtures by integral equation theory and molecular dynamics simulations (2002)

A dielectrically adjusted version of the RISM equation for the situation of ions in mixed solvents is applied to model mixtures of water with methanol in concentrations covering the complete concentration range. Calculated structures from the integral equation theory are compared to corresponding results from NVT molecular dynamics simulations. The structure calculated from the integral equation is generally in good agreement with the molecular dynamics results. The agreement in calculated energies between integral equation theory and molecular dynamics simulations are also generally good over the entire concentration range for the specific model applied. For the first time this type of integral equation theory is also applied to the direct calculation of free energy. For the specific water model the free energy is lower than the experimental value for pure water. Under-predictions of the structure and corresponding higher entropy for the specific water model might be one of the reasons for these results. The dielectric constant in a uniform liquid mixture can be described in terms of the dipole moments of the molecules involved and the molecular correlation functions for the different molecular pair combinations in the mixture. In this work I reformulate the theory into a corresponding interaction site formulation. The reformulated theory is illustrated for the water/methanol model mixtures.
Model-Based Self-Aware Performance and Resource Management Using the Descartes Modeling Language (2016)

Modern IT systems have increasingly distributed and dynamic architectures providing flexibility to adapt to changes in the environment and thus enabling higher resource efficiency. However, these benefits come at the cost of higher system complexity and dynamics. Thus, engineering systems that manage their end-to-end application performance and resource efficiency in an autonomic manner is a challenge. In this article, we present a holistic model-based approach for self-aware performance and resource management leveraging the Descartes Modeling Language (DML), an architecture-level modeling language for online performance and resource management. We propose a novel online performance prediction process that dynamically tailors the model solving depending on the requirements regarding accuracy and overhead. Using these prediction capabilities, we implement a generic model-based control loop for proactive system adaptation. We evaluate our model-based approach in the context of two representative case studies showing that with the proposed methods, significant resource efficiency gains can be achieved while maintaining performance requirements. These results represent the first end-to-end validation of our approach, demonstrating its potential for self-aware performance and resource management in the context of modern IT systems and infrastructures.
Oligopeptides as Biomarkers of Cyanobacterial Subpopulations. Toward an Understanding of Their Biological Role (2014)

Cyanobacterial oligopeptides comprise a wide range of bioactive and/or toxic compounds. While current research is strongly focused on exploring new oligopeptide variants and their bioactive properties, the biological role of these compounds remains elusive. Oligopeptides production abilities show a remarkably patchy distribution among conspecific strains. This observation has prompted alternative approaches to unveil their adaptive value, based on the use of cellular oligopeptide compositions as biomarkers of intraspecific subpopulations or chemotypes in freshwater cyanobacteria. Studies addressing the diversity, distribution, and dynamics of chemotypes in natural systems have provided important insights into the structure and ecology of cyanobacterial populations and the adaptive value of oligopeptides. This review presents an overview of the fundamentals of this emerging approach and its most relevant findings, and discusses our current understanding of the role of oligopeptides in the ecology of cyanobacteria.
