Specular color imaging on a metallic substrate (2013)

We propose a full reproduction workflow for printing color images on metallic substrates. It relies on an ink spreading enhanced cellular Yule-Nielsen modified spectral Neugebauer model, calibrated with 35 color samples printed on the metal film and measured under specular reflection. The calibration accounts for the different phenomena contributing to the reflectance of halftone prints on metal: specular reflection by the metal film substrate of light traveling across the inks, illumination and viewing geometry, shadowing effect induced by the ink and difference in surface structure between the inked and non-inked metal halftone elements. The model enables predicting printable colors with an average CIELAB ΔE94 error of 1.7. Thanks to the model, the metal print gamut is established and a 3D table provides the correspondence between printable metallic colors viewed under specular reflection and the corresponding ink surface coverages. The input sRGB gamut is mapped into the print gamut. At halftone image generation time, surface coverages of the inks yielding the desired gamut mapped input colors are obtained from the 3D table. These ink surface coverages yield the ink separations that are halftoned and printed. The resulting color images printed on a silver substrate viewed under specular reflection reproduce the hues at a high degree of fidelity. The luminance of metallic prints under specular observation is generally higher than the luminance of paper under the same illuminating conditions. Therefore, the printed metallic colors appear more colorful. Such metal prints are attractive for design, art and publicity. Their high brightness immediately strikes the observer and transmits the message incorporated into the reproduced picture or artwork.
Unconstrained Heart Rate Estimation System in Bed (2007)

It is widely known that autonomic nervous system (ANS) is one of the indices to indicate the wakefulness of person. Therefore measuring the biosignals relating with the ANS during sleep is required to evaluate sleep quality. There are many researches that heart rate derived from the electrocardiogram (ECG) is good index to show the sympathetic or parasympathetic activities. To assess the quality of sleep, polysomnagraphy is used as golden standard but subjects have to attach many of sensors to their body and it is not only complicate, but also influence their sleep. In this study, to measure the autonomic nervous activities, we introduce newly developed system using load-cell. The sensors installed bottom of the bed measure the ballistocardiogram, mechanical vibration of heart. Ballistocardiogram is one of the nonintrusive methods to measure the heart rates unconstrainedly. By comparing with reference signal, ECG using Ag-AgCl electrodes, we validated our system with the four subjects. The results show comparison of LF/HF ratio, one of the heart rate variability, measured from the load-cells and Ag-AgCl electrodes for the each sleep stage, deep sleep, light sleep and REM sleep. It shows the different pattern for the light and deep sleep but contrary to our expectation, REM sleep doesn't indicate the highest value. LF/HF ratio measured from both methods have no significant differences.
A packet network for BISDN applications (2003)

A description is given of a broadband packet network architecture suitable for evolving the existing public switching network into an all-fiber broadband network for integrated voice, data, and video applications. The architecture takes into account the needs for bit-rate flexibility, robustness to service evolution, and interoperability with the existing circuit-switched public network. Key features of the network include internally nonblocking broadband packet switches, integrated network transport, and simplified network-routing algorithms. The feasibility and the benefits of a broadband public network using packet technologies are shown.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Resolving webuser on the fly (2002)

Identity authentication systems and procedures are rapidly becoming one of the central issues in the practice and study of information systems development and security. Requirements for Web Transaction Security (WTS) include strong authentication of user, non-repudiation and encryption of all traffic. In this paper, we present an effective mechanism involving two different channels, which addresses the prime concerns involved in the security of the Electronic Commerce Transactions (ECT) viz. the user authentication and the non-repudiation. Although the product is primarily targeted to provide a fillip to the transaction carried out over the web, this product can also be effectively used for transactions that are carried out other than Internet where user authentication is required.

Black start technology for local power grid via PMSG-based wind power generation (2017)

In the power grid lacking conventional power sources for black start, adopting wind farm as a power source for black start is a beneficial attempt. With Jangsu local power grid as research object in China, and combining with the special geographical and demand of the local power grid, a black start scheme using permanent-magnet synchronous generator(PMSG)-based wind farm as black start power is proposed. The diesel generator is used as an external supporting power in this scheme, which provides voltage and frequency reference for the black start isolated network system, then the self-starting of Huarun(HR) wind farm is realized under the support of diesel generator, and HR wind farm with diesel generator is used to start the adjacent auxiliary of Tianying(TY) thermal power plant finally. The simulation analysis the transient process of wind farm self-starting, the empty charge of transformers and line, and auxiliary startup of thermal power plant, which provides the necessary theoretical foundation for the black start filed experiment of local power grid.
The Vesicular Acetylcholine Transporter Is Required for Neuromuscular Development and Function (2009)

The vesicular acetylcholine (ACh) transporter (VAChT) mediates ACh storage by synaptic vesicles. However, the VAChT-independent release of ACh is believed to be important during development. Here we generated VAChT knockout mice and tested the physiological relevance of the VAChT-independent release of ACh. Homozygous VAChT knockout mice died shortly after birth, indicating that VAChT-mediated storage of ACh is essential for life. Indeed, synaptosomes obtained from brains of homozygous knockouts were incapable of releasing ACh in response to depolarization. Surprisingly, electrophysiological recordings at the skeletal-neuromuscular junction show that VAChT knockout mice present spontaneous miniature end-plate potentials with reduced amplitude and frequency, which are likely the result of a passive transport of ACh into synaptic vesicles. Interestingly, VAChT knockouts exhibit substantial increases in amounts of choline acetyltransferase, high-affinity choline transporter, and ACh. However, the development of the neuromuscular junction in these mice is severely affected. Mutant VAChT mice show increases in motoneuron and nerve terminal numbers. End plates are large, nerves exhibit abnormal sprouting, and muscle is necrotic. The abnormalities are similar to those of mice that cannot synthesize ACh due to a lack of choline acetyltransferase. Our results indicate that VAChT is essential to the normal development of motor neurons and the release of ACh.
Diamond knife corneal incisions. (1984)

In the following study, eight linear corneal incisions were made in two human cadaver eyes with three diamond-bladed knives: the KOI, Cooper, and Micra micrometer knives. Prior to the incisions, ultrasonic pachymetry readings of the corneas were recorded, and all knives were calibrated to a guarded cutting depth of 0.55 mm (550 microns). Following the incisions, the corneas were fixed, sectioned, and incision depth carefully measured histologically. In all but two incisions made with the Cooper knife, the incision depth was significantly or highly significantly greater than the calibrated diamond length. There was a significant or highly significant difference in depth among incisions made with the same knife, as well as among incisions made with different knives. Depth variability was noted for all knives except for two comparisons between incisions made with a Micra and KOI knife, and one comparison between two incisions, both made with the Cooper knife. Difference in knife design which may account for the variation of incision depth and contribute to the unpredictability of radial keratotomy is discussed.
The Geographic Distribution of Iowa Devonian Echinoderms (1923)

In connection with a paper recently prepared for the Iowa Geological Survey, entitled "Echinoderms of the Iowa Devonian," some interesting facts regarding the geographic distribution of the echinoderms of this system were ascertained. Forty-three species and two varieties constitute the total number studied. Of these four are cystids, four are blastoids, thirty are crinoids, and five are echinoids. The two varieties consist of one camerate crinoid and one echinoid. Seven of the species are known to occur in the Devonian of neighboring states.
The relation between dopamine D2 receptor density and personality: preliminary evidence from the NEO personality inventory-revised. (2000)

The results fail to replicate the findings of previous studies reporting an association between DA D2 receptor density and personal detachment, suggesting that the relation is relatively specific to the trait defined by the Karolinska Scales of Personality. The relation between a nonclinical personality trait of depression and DA D2 binding, if replicated, may help to elucidate the role of dopamine in depression.
Length measurement using infrared two-wavelength He–Xe laser interferometer (1982)

The results of length measurements made with a 800-mm-long gauge block, using an infrared interferometer whose light source is a 3.51– 3.37-μm simultaneous operation He–Xe laser, are described. The wavelength ratio of the 3.51-μm line to the 3.37-μm line is determined to an accuracy of 1.7×10−8 and the absolute length of the gauge block is uniquely determined to an accuracy of 4.9×10−8 by the method of excess fractions. This interferometer has a possibility of measuring lengths up to several meters.

Value of information exposed: Wireless networking solutions to the parking search problem (2011)

Our work draws on a concrete parking space search application to explore fundamental tradeoffs of wireless networking solutions to the provision of real-life services. In particular, we consider a city area, wherein each vehicle (mobile user) moves towards a chosen destination and seeks vacant parking space in its vicinity. Three main approaches to the parking space search problem are investigated, each representing a distinct paradigm of how wireless networking communications can assist the information management process. In the first approach, the vehicles execute the currently common “blind” sequential search for parking space by wandering around the destination. In the second distributed approach, the vehicles, while moving around the area, opportunistically collect and share with each other information on the location and status of each parking spot they encounter. Finally, with the third approach, the allocation of parking spots is managed by a central server availing global knowledge about the parking space availability. We compare the three approaches with respect to the time and distance vehicles need to travel before they park as well as the proximity of the assigned parking spots to the travel destinations. Results obtained under two scenarios for the user travel preferences (uniformly distributed travel destinations vs. a single hotspot road), reveal that the relative performance of the three solutions can vary significantly and not always inline with intuition. In the hotspot scenario, the centralized system consistently yields the minimum times and distances at the expense of more distant parking spot assignments; whereas, when user travel destinations are uniformly distributed, the relative performance of all three schemes changes as the vehicle volume grows, with the centralized approach gradually becoming the worst solution. We discuss the way each approach modulates the information dissemination process in space and time and resolves the emerging competition for the parking resources. We also outline models for getting analytical insights to the behavior of the centralized approach.
Bringing virtual events into real life in Second Life home automation system (2011)

In this paper we propose the design and development of a prototype system to monitor and control a physical home and to bridge the interaction gap between the virtual and real world device control mechanism. We created a virtual 3D home in Second Life that mimics the look of a physical home. In the physical home environment different devices and sensors are connected in order to ensure a safe and automated home. Any event that occurs in the physical space of the smart home is then synchronized with the virtual environment. More importantly, the virtual home interface provides the option to control the physical smart devices. By using the Second Life virtual interface the home owner have a better look to monitor or control the home appliances. As per the initial experimentation, we found out that the proposed approach of Second Life based home automation system is appealing and useful to the user.

French Empire: 11. Pacific (2016)

Abstract In the mid‐ and late 1800s, France acquired several colonies in the South Pacific: Tahiti and the other islands of French Polynesia, New Caledonia, and Wallis and Futuna, as well as an interest in the Anglo‐French condominium of the New Hebrides. The French transported convicts to New Caledonia from the 1860s to the 1890s, but its major resource was and remains nickel. The myths of paradise found and lost endured in Tahiti, which gained new importance for France from the 1960s to the 1990s as a site for nuclear tests. France reluctantly acceded to independence for the New Hebrides in 1980, but the other islands remain French territories; a violent conflict between pro‐ and anti‐independence groups troubled New Caledonia in the 1980s.
Simulator for computer-aided design of holograms (2001)

A simulator for the computer-aided design of holograms is developed. The direction and intensity of the reconstructed beam are calculated using the Kirchhoff diffraction integral and Kogelnik's coupled- wave theory. Grating distortions induced by physical changes in the re- cording medium are evaluated using the diffraction integrals, and imag- ing characteristics are analyzed using ray tracing. Simulator results can be used to evaluate wavefront aberrations of the reconstructed images, and holograms that compensate for aberrations can be designed by the simulator. Examples are given where recording and reconstruction wave- lengths are different and where the grating is distorted by nonuniform shrinkage of the medium. Also, to illustrate practical application, a holo- graphic optical element lens and a wavelength demultiplexer are de- signed and evaluated.9 © 2001 Society of Photo-Optical Instrumentation Engineers. Holographic optical elements ~HOEs! are useful for assem- bling compact optical systems. Since a hologram is a kind of diffractive optical element, the position of the recon- structed image is changed and aberrations are induced when the reconstruction conditions are different from the recording conditions. Also, the intensity of the recon- structed beam is reduced when the physical properties of the recording medium are changed during the development process. Therefore it is necessary to take the reconstruction and imaging characteristics into consideration when design- ing holograms. The reconstruction characteristics of holograms can be analyzed using the Kirchhoff diffraction integral 1 or coupled-wave theory. 2 The imaging characteristics of holo- grams can be analyzed using wavefront matching 3-5 or ray tracing. 6,7 However, it is difficult to design holograms by analytical methods because of the nonlinearity of the evalu- ation function, but computer-aided design can be effective. Latta's ray-tracing program can be used to design holograms, 8,9 but is inconvenient because of its specializa- tion for the analysis of imaging characteristics. Sweatt has presented the ultra-high-index method 10,11 for designing ho- lograms using general optical design tools. However, com- mercially available tools are not suitable because they em- phasize the design of bulk-type lenses. Therefore a computer-aided design tool specialized for holography is needed.
List Scheduling Algorithm for Heterogeneous Systems by an Optimistic Cost Table (2014)

Efficient application scheduling algorithms are important for obtaining high performance in heterogeneous computing systems. In this paper, we present a novel list-based scheduling algorithm called Predict Earliest Finish Time (PEFT) for heterogeneous computing systems. The algorithm has the same time complexity as the state-of-the-art algorithm for the same purpose, that is, O(v2.p) for v tasks and p processors, but offers significant makespan improvements by introducing a look-ahead feature without increasing the time complexity associated with computation of an optimistic cost table (OCT). The calculated value is an optimistic cost because processor availability is not considered in the computation. Our algorithm is only based on an OCT that is used to rank tasks and for processor selection. The analysis and experiments based on randomly generated graphs with various characteristics and graphs of real-world applications show that the PEFT algorithm outperforms the state-of-the-art list-based algorithms for heterogeneous systems in terms of schedule length ratio, efficiency, and frequency of best results.

senseGUI – A DECLARATIVE WAY OF GENERATING GRAPHICAL USER INTERFACES (2008)

A declarative way of creating GUIs is also known as model-based generation. Most of existing solutions require dedicated tools and quite complicated knowledge from the programmer. They also use special languages. In contrast, we propose a method which utilizes annotations existing in present programming languages. The method greatly improves generating common GUIs for popular languages. Annotations allow the programmer for marking particular parts of a source code defining class structures. Using such simple annotations, the programmer can describe basic properties of the desired GUI. In the simplest form it is enough just to mark attributes (or methods) for which widgets should be created. There is also a way to define more detailed description including labels, the order of items, different widgets for particular data items, etc. Using a generated form, the application user can create, edit and see instances of data objects. Our research is supported by a working prototype library called senseGUI (Java).
One-year follow-up of first consecutive 100 zirconia dental implants in humans: a comparison of 2 different rough surfaces. (2007)

From the preliminary results of this investigation, it can be concluded that zirconia dental implants with roughened surfaces might be a viable alternative for tooth replacement. Further follow-up is needed to evaluate the long-term success rates of the implant surfaces studied.
