SLAM for Indoor Environment Using Stereo Vision (2010)

In this paper, we propose a system which extracts image line features from stereo camera as landmarks, and use stereo property to obtain the 3D vertical line landmarks. This system is based on the EKF. To handle with measurement uncertainty, we use two different observation models. One is nearby landmark model, the other one faraway landmark model. Our system contains a wheeled robot, which serves as our experiment platform, odometer data, image line segmentation, landmark's 3D position reconstruction, and Extended Kalman Filter. Our system can use a single sensor to implement the EKF-based SLAM in real time. It can work in an environment lacking texture. The robot moves at a speed of 0.1m/s and simultaneously locates itself. The estimated error and computational time of this system are acceptable.

Spontaneous Chromosome Breakages Observed in a Phenotypically Normal Woman and Her Two Abortuses (With 6 Text-figures and 3 Tables) (1968)

With 6 Text-figures and 3 Tables) \Vhile working on chromosomal surveys of induced and spontaneous abortions, the authors had a chance to observe a high incidence of chromosome breakages in two abortuses from one and the same woman, one from a spontaneous abortion and the other from an induced abortion.The former was preliminarily reported in a previous paper (Makino et al., 1967).Further investigation has revealed that a similar chromosome condition has occurred in leucocyte cultures from the same woman, clinically normal.The present paper reports the results of chromosomal studies in the woman and her two abortuses with some remarks on a possible genetic significance of chromosome breakages in relation to abortion.The authors wish to express sincere thanks to Professor Sajiro Makino for his direction and improvement of the manuscript and to Dr. Motomichi Sasaki for his invaluable advi('e and suggestion.
Signal transduction pathways involved in the activation of NF-kappa B, AP-1, and c-fos by Mycoplasma fermentans membrane lipoproteins in macrophages. (1999)

Mycoplasma fermentans-derived membrane lipoproteins (LAMPf) have been demonstrated to stimulate monocytic cells and to induce the secretion of proinflammatory cytokines by a mechanism involving the triggering of protein tyrosine kinase and mitogen-activated protein kinase cascades. Herein, we have examined the effects of LAMPf on the activation of a series of transcription factors potentially involved in cytokine gene expression. LAMPf was capable of inducing NF-kappa B, activated protein 1 (AP-1), and c-fos activation in macrophages and of stimulating NF-kappa B and AP-1 transactivation. Furthermore, we have delineated the contribution of each mitogen-activated protein kinase pathway to the LAMPf-mediated activation of AP-1, c-fos, and NF-kappa B. Whereas the selective extracellular signal-regulated kinase pathway inhibitor PD-98059 did not affect the LAMPf-mediated transactivation of AP-1, c-fos, or NF-kappa B, the specific p38 inhibitor SB203580 abrogated this activity. A c-Jun N-terminal kinase-dominant negative was shown to block the activation of AP-1 without altering NF-kappa B or c-fos activation by LAMPf. In addition, D609, a selective inhibitor of phosphatidylcholine-specific phospholipase C, was shown to block both translocation and transactivation of either NF-kappa B or AP-1 in response to LAMPf. Although LAMPf-mediated macrophage activation is CD14 independent, we could not distinguish between the intracellular mechanisms leading to the macrophage activation triggered by either LPS or LAMPf. This suggests that macrophages display a common signaling machinery leading to the secretion of proinflammatory cytokines in response to different bacterial products. The comprehension of these mechanisms may help to better understanding the bacterial pathogenesis and to elucidate general mechanisms of macrophage activation leading to cytokine secretion.
Identification of volatile compounds released from dry scented Thai flowers and their potential application in flower-mixed tea (2009)

Scented Thai flowers have been traditionally used for several applications. One traditional practice is to use flowers in food and drink, for example, adding scented flowers in sweets and beverages. Scented flowers provide good aroma, resulting in good emotions and commonly known as aromatherapy. The purpose of this research was to develop a new tea beverage with increased aroma of scented Thai flowers. The experiments were conducted in two steps (i) identification of volatile chemicals of dried scented flowers and (ii) consumer acceptance test of flower-mixed tea. Four scented flowers: Champak (Michelia champaca L.), Indian Cork flower (Millingtonia hortensis L.), Jasmine (Jasminum sambac L.), and Ylang Ylang (Cananga odorata Lam.) were selected. The headspace volatile compounds of the dried scented flowers were sampled by solid phase microextraction using Carboxen/Polydimethylsiloxen fibre and characterised using gas chromatography-mass spectrometry. The identified volatile compounds were grouped as alcohols, aldehydes, ketones, esters, ethers and terpenes. In every sample, the four sesquiterpenes, caryophyllene, β-bergamotene, α-cubebene and β-cubebene were found in high amounts. Characteristic compounds were also found in each sample. Champak consisted of β-terpinene, eucalyptol and epoxpylinalool; Indian cork flower consisted of 1-octen-3-ol and linalyl anthranilate; Ylang Ylang consisted of germacrene D and α-longipinene; and Jasmine consisted of linalool and (Z)-β-farnesene. The consumer acceptance test (n = 406) of dried flower tea was performed by 9-point hedonic scale. The overall liking, the flower aroma preference and the acceptance of flower-mixed tea of those four flowers were significantly different. The most preferred was green tea mixed with Jasmine flowers (6.14 ± 1.68) obtaining the highest overall liking score, while green tea mixed with Champak (6.63 ± 1.85) resulted in the highest rating of

Index- Based Futures And Options Markets In Real Estate (1993)

Most institutional and individual portfolios are very undiversified in real estate: many hold no real estate at all, many have holdings highly concentrated in certain regions or types of real estate. The risk of these concentrated holdings is not hedged. We propose here that cash-settled futures and options markets be opened on real estate to better allow diversification and hedging, and show that these markets solve problems that have hampered other real estate hedging media in the past. Related institutions, such as home equity insurance, might develop around the futures and options markets. The establishment of these markets is likely to increase the quantity of reproducible real estate, and lower rents on real estate. It may also reduce the amplitude of speculative real estate price movements and dampen the business cycle.
<title>High-power double-clad fiber lasers: a review</title> (2002)

High power fiber lasers are now mature products and have numerous applications as medical, military, industrial processing and telecommunication. Usually single mode fiber lasers are pumped with single mode pump diode featuring low output power. Double-clad fiber lasers (DCFL) overcome the issue related to low power single mode pump diodes to take fully advantage of large low cost multimode diodes. Improvement in high power multimode diode combined with double-clad fiber technology permit to DCFLs to be very efficient and promising. They are mainly operating in CW regime however Q-switch or mode lock regimes are also achievable. DCFLs in CW regime can feature several watt output power. Up to 30W CW Ytterbium DCFL has been demonstrated indicating that fiber laser is able to handle very high optical power without any optical damage. Also fiber lasers included tens of meters long fiber, improving heat dissipation and leading to a less critical thermal management compare to bulk lasers. For terrestrial telecommunication applications, DCFLs are mainly operating in CW regime and in particular, Ytterbium DCFL is largely used as a pump for Raman Fiber Laser (RFL). The RFLs are used for components testing, pumping EDFAs and Raman amplifiers.

Fuel Injection by a Thermal Microinjector (1999)

Abstract This paper reports a new application of a thermal microinjector for fuel injection. The paper estimates the ejected velocity of the diesel fuel droplet, and the minimum temperature for bubble formation. The fuel spray penetration is calculated by solving nonlinear equations of motion. Analysis of the temperature profile evolution and activation curve between water and diesel fuel is helpful for optimization of the microinjector design. The microinjector is fabricated using combined surface and bulk micromaching. The preliminary testing of the microinjector with fuel demonstrates the possibility of droplet ejection. Also, discussion about design issues reveals some advantages of the microinjector over the conventional fuel injector.
Noduloulcerative or "malignant" syphilis occurring in an otherwise healthy woman: report and review of a dramatic dermatosis. (1990)

We present the case of an otherwise healthy woman with noduloulcerative ("malignant") syphilis, the first female patient reported with this dermatosis in fifty years. This rare form of secondary syphilis is characterized by noduloulcerative lesions with rupioid crusts that dramatically involve the face while usually sparing the palms and soles. The aggression and destruction of the skin lesions may mimic that of other granulomatous and infiltrative dermatoses. Since the incidence of syphilis is increasing, physicians should be aware of this variant that is so disfiguring it has historically been referred to as lues maligna.
Abstracting application-level security policy for ubiquitous computing (2021)

In the future world of Ubiquitous Computing, tiny embedded networked computers will be found in everything from mobile phones to microwave ovens. Thanks to improvements in technology and software engineering, these computers will be capable of running sophisticated new applications constructed from mobile agents. Inevitably, many of these systems will contain application-level vulnerabilities; errors caused by either unanticipated mobility or interface behaviour. Unfortunately existing methods for applying security policy – network firewalls – are inadequate to control and protect the hordes of vulnerable mobile devices. As more and more critical functions are handled by these systems, the potential for disaster is increasing rapidly. To counter these new threats, this report champions the approach of using new application-level security policy languages in combination to protect vulnerable applications. Policies are abstracted from main application code, facilitating both analysis and future maintenance. As well as protecting existing applications, such policy systems can help as part of a security-aware design process when building new applications from scratch. Three new application-level policy languages are contributed each addressing a different kind of vulnerability. Firstly, the policy language MRPL allows the creation of Mobility Restriction Policies, based on a unified spatial model which represents both physical location of objects as well as virtual location of mobile code. Secondly, the policy language SPDL-2 protects applications against a large number of common errors by allowing the specification of per-request/response validation and transformation rules. Thirdly, the policy language SWIL allows interfaces to be described as automata which may be analysed statically by a model-checker before being checked dynamically in an application-level firewall. When combined together, these three languages provide an effective means for preventing otherwise critical application-level vulnerabilities. Systems implementing these policy languages have been built; an implementation framework is described and encouraging performance results and analysis are presented.
Interaction of Image Quality Metrics (2002)

Many image quality characteristics interact. Consequently, improving one characteristic may either enhance or degrade another. As we strive to improve cinema image quality these interactions become more important, especially if new robust cinema delivery systems are to be realized.

Ion Transport within High Electric Fields in Nanogap Electrochemical Cells (2015)

Ion transport near an electrically charged electrolyte/electrode interface is a fundamental electrochemical phenomenon that is important in many electrochemical energy systems. We investigated this phenomenon using lithographically fabricated thin-layer electrochemical cells comprising two Pt planar electrodes separated by an electrolyte of nanometer thickness (50-200 nm). By exploiting redox cycling amplification, we observed the influence of the electric double layer on transport of a charged redox couple within the confined electrolyte. Nonclassical steady-state peak shaped voltammograms for redox cycling of the ferrocenylmethyltrimethylammonium redox couple (FcTMA(+/2+)) at low concentrations of supporting electrolyte (≤10 mM) results from electrostatic interactions between the redox ions and the charged Pt electrodes. This behavior contrasts to sigmoidal voltammograms with a diffusion-limited plateau observed in the same electrochemical cells in the presence of sufficient electrolyte to screen the electrode surface charge (200 mM). Moreover, steady-state redox cycling was depressed significantly within the confined electrolyte as the supporting electrolyte concentration was decreased or as the cell thickness was reduced. The experimental results are in excellent agreement with predictions from finite-element simulations coupling the governing equations for ion transport, electric fields, and the redox reactions. Double layer effects on ion transport are generally anticipated in highly confined electrolyte and may have implications for ion transport in thin layer and nanoporous energy storage materials.
Imaging in multiple sclerosis (2005)

ultiple sclerosis (MS) is a common central nervous system (CNS) disease characterised pathologically by the development of multifocal inflammatory demyelinating white matter lesions. Magnetic resonance imaging (MRI) is the gold standard imaging technique for the identification of demyelinating lesions which can be used to support a clinical diagnosis of MS, and MS can now be diagnosed in some patients after a clinically isolated syndrome (CIS) using new MRI diagnostic criteria. Clinical trials of disease modifying treatments include MRI outcome measures of disease activity. The use of MR techniques to study the evolution of MS pathology in vivo is an important tool for obtaining better insights into pathophysiological mechanisms underlying the clinical course. This article will concentrate on the practical application of MRI in the management of MS.
Unit Testing: Static Analysis and Dynamic Analysis (2009)

Unit testing is used by programmers to discover bugs with least cost. Static unit testing offers the minimum path coverage while dynamic unit testing detects control and data flow problems. In this paper, we develop a method to translate a program from "character" mode to "graph" mode, so that the tester can picture the existing code without losing the ability to generate tests. In static analysis phrase, this method can help testers to detect grammar errors, extra code, non-initialized variables, search paths to cover the code, and generate tests. In dynamic phrase, testers can get benefit from this method to check internal logic, exception and boundary conditions.

NBTI enhancement by nitrogen incorporation into ultrathin gate oxide for 0.10-μm gate CMOS generation (2002)

We investigated the degradation of device reliability due to Negative Bias Temperature Instability (NBTI) of PMOSFET with ultrathin gate oxide. It was experimentally demonstrated that the chemical reactions at the gate oxide/substrate interface and/or diffusion of hydrogen related species are the major cause of the NBTI. We also found that nitridation of gate oxide enhances NBTI. In order to suppress the NBTI, the density of hydrogen terminated silicon bond at the interface needs to be minimized. Thus, the concentration of nitrogen in thin gate oxide has to be optimized in terms of the reliability reduction due to NBTI.
A visual consistent adaptive image thresholding method (2015)

Image thresholding method is an important preprocessing step in many applications of image processing. In this paper, we present a visual consistent adaptive image thresholding method, by combining the thresholding process with the characteristics of human visual system. In the proposed algorithm, we first roughly classify the image pixels into two categories. Then two sub-images are constructed to retain the essential information of the original image. For each sub-image, a corresponding global optimal threshold is calculated by optimizing an objective function. Finally, a visual consistent binary image is produced by combining the results from the previous steps with the information of pixels in each category. The proposed method has been tested on some different images, and the results are also compared with a number of known algorithms in the literature. The experimental results demonstrate that the overall visual qualities of our method are more suitable for human visual perception.
