A Duplication-Aware SSD-Based Cache Architecture for Primary Storage in Virtualization Environment (2015)

With the advantages of low latency, high performance, and low power consumption, solid state drives (SSDs) have been widely deployed as the cache layer between memory and back-end low-speed storage devices to narrow the performance gap between CPU and storage system. However, in virtualization environment, the high integration of virtual machines can introduce a lot of duplicate data blocks in the cache device. Existing cache architectures and replacement algorithms rarely take this situation into consideration. This greatly limits the efficient use of the cache device. For this case, we proposed a duplication-aware SSD-based cache architecture. In this architecture, duplicate data blocks can be significantly reduced, and the utilization efficiency of the cache device will be notably improved. Furthermore, to reduce the cache replacement overhead, we also proposed an improved adaptive replacement cache (ARC)-based replacement strategy, which we named D-ARC. Experiment results show that, in some situations, our cache architecture can improve the cache hit ratio by five times, reduce the average I/O latency by 63%, and eliminate SDD writes by 81%. Compared with the ARC-based replacement strategy, D-ARC can provide a performance improvement by about 16% if the configuration is set appropriately.

A Method for Obtaining Human Skin Color Pixels Based on Surrounding Factors (2019)

Accurate skin color detection methods are very valuably used in diverse fields such as face recognition and tracking, facial expression recognition, adult image detection and healthcare. In this paper, the performances of diverse skin color detection algorithms were comparatively evaluated as the distance to the subject was changed and the color of the subject background was changed in the environment where normal light and indoor lighting were added. The test was conducted by selecting 2 males and 1 female having different skin tones as the subjects and dividing the background colors into white, black, orange, pink and yellow. The skin color extraction algorithms used for performance evaluation were Peer algorithm, NNYUV algorithm, NNHSV algorithm, LutYUV algorithm, and Kismet algorithm. The test was conducted by limiting the distance between camera and subject to 60cm to 120cm. As a result of conducting the performance measurement test, the performances of the algorithms showed differences according to the changes made to the subject background. In general, NNHSV and NNYUV algorithms using neural network and LutYUY algorithm showed stable results. As far as the remaining algorithms were concerned, their skin color detection rates were significantly influenced by the changes made to the background. This paper is expected to be effectively utilized in developing an adaptive and highly accurate environment-based skin color extraction algorithm suitable for actual environments where dynamic changes are made to the subject's surrounding environments.

ItCompress: an iterative semantic compression algorithm (2004)

Real datasets are often large enough to necessitate data compression. Traditional 'syntactic' data compression methods treat the table as a large byte string and operate at the byte level. The tradeoff in such cases is usually between the ease of retrieval (the ease with which one can retrieve a single tuple or attribute value without decompressing a much larger unit) and the effectiveness of the compression. In this regard, the use of semantic compression has generated considerable interest and motivated certain recent works. We propose a semantic compression algorithm called ItCompress ITerative Compression, which achieves good compression while permitting access even at attribute level without requiring the decompression of a larger unit. ItCompress iteratively improves the compression ratio of the compressed output during each scan of the table. The amount of compression can be tuned based on the number of iterations. Moreover, the initial iterations provide significant compression, thereby making it a cost-effective compression technique. Extensive experiments were conducted and the results indicate the superiority of ItCompress with respect to previously known techniques, such as 'SPARTAN' and 'fascicles'.
Rapid prototyping of infrared bandpass filters using aperture array lithography (2005)

We demonstrate the prototyping of infrared bandpass filters, which consist of cross-shaped openings in a thin gold film, using ion beam aperture array lithography. In the lithography process, a stencil mask containing a periodic array of square apertures is irradiated by a broad beam of helium ions. The ions that pass through the openings expose the resist on a substrate that is placed in close proximity and cross-shaped filter structures are printed by moving the stage underneath the substrate, thus allowing for rapid formation of periodic patterns. We have fabricated filter patterns with peak transmittance ranging from 53% to 67% at wavelengths between 1.2 and 1.3μm that exhibit high reflectance for longer wavelength radiation. The prototyping throughput for masks with 2μm pitch patterns was about 2cm2∕h. The spectral performance of the prototyped filters was measured. Large-area, second-generation masks with 667nm pitch had a lithography throughput of 300cm2∕h and were used to print filter patterns of similar quality.
Interpretation of some experimental data concerning bent monochromators for synchrotron X-ray radiation (1978)

Some recent experimental data concerning curved monochromators for X-ray synchrotron radiation have been interpreted by using a simple model based on the dynamical theory of diffraction. In particular, a large gain of about 30 observed for Mo Kα radiation by bending a quartz crystal is explained.
Kinetic and Nuclear Magnetic Resonance Studies of Xylose Metabolism by Recombinant <i>Zymomonas mobilis</i> ZM4(pZB5) (2000)

The specific rates of growth, substrate utilization, and ethanol production as well as yields of biomass and ethanol production on xylose for the recombinant Zymomonas mobilis ZM4(pZB5) were shown to be much less than those on glucose or glucose-xylose mixtures. Typical fermentations with ZM4(pZB5) growing on glucose-xylose mixtures followed two-phase growth kinetics with the initial uptakes of glucose and xylose being followed by slower growth and metabolic uncoupling on xylose after glucose depletion. The reductions in rates and yields from xylose metabolism were considered in the present investigation and may be due to a number of factors, including the following: (i) the increased metabolic burden from maintenance of plasmid-related functions, (ii) the production of by-products identified as xylitol, acetate, lactate, acetoin, and dihydroxyacetone by (13)C-nuclear magnetic resonance (NMR) spectroscopy and high-performance liquid chromatography, (iii) growth inhibition due to xylitol by the putative inhibitory compound xylitol phosphate, and (iv) the less energized state of ZM4(pZB5). In vivo (31)P-NMR studies have established that the levels of NTP and UDP sugars on xylose were less than those on glucose, and this energy limitation is likely to restrict the growth of the recombinant strain on xylose media.

All quartz surface mount resonators (2002)

This paper presents the electrical and mechanical characteristics of high frequency "all-quartz" surface mount resonators. All-quartz surface mount resonators are fabricated using a suitably electroded quartz crystal base plate and a cover plate of quartz which are bonded to a specially formed, electroded AT-cut quartz resonator plate with epoxy resin to create a hermetic seal. Methods of production have been developed which allow for the manufacture of this type of resonators having fundamental mode frequencies in the range from 3.5 MHz to more than 50 MHz. The paper presents the results of aging and environmental studies, that show that the frequency stability, equivalent series resistance and other electrical properties of the all-quartz surface mount resonators are equivalent to the values of the same parameters of quartz resonators which are encapsulated in SMT ceramic enclosures. However, the dimensions of the all-quartz surface mount resonators have a much lower height and smaller volume and they exhibit substantially greater resistance to shock and vibration than the ceramic enclosed resonators of the same frequency.
Survival of lux-lac-marked biosurfactant-producing Pseudomonas aeruginosa UG2L in soil monitored by nonselective plating and PCR (1994)

Two reporter systems, lacZY and luxAB, were stably integrated into the chromosome of Pseudomonas aeruginosa UG2, a biosurfactant-producing strain. Growth and rhamnolipid production of the UG2 wild-type and reporter gene-bearing UG2L strains were similar in liquid culture. A spontaneous rifampin-resistant detecting UG2Lr, allowed antibiotic selection. Phenotypic characteristics were compared for usefulness in detecting UG2Lr colonies: morphology, fluorescent pigment production, light emission (lux), X-Gal (5-bromo-4-chloro-3-indolyl-beta-D-galactopyranoside) cleavage (lac), and rifampin resistance. Survival patterns of UG2, UG2L, and UG2Lr strains were similar in sandy loam soil microcosms over 12 12 weeks. The lac marker was not suitable for monitoring P. aeruginosa UG2Lr in soil since 20 to 42% of cultured, aerobic, heterotrophic soil microorganisms formed blue, lactose-positive colonies. The lux genes provided a stable and unequivocal reporter system, as effective as conventional antibiotic plating, for tracking microorganisms nonselectively at 10(3) CFU/g of soil. Three months after inoculation into oil-contaminated and uncontaminated soil microcosms, UG2Lr cells were recovered at 10(7) and 10(4) cells per g (dry weight) of soil, respectively. Detection by PCR amplification of part of the luxA gene confirmed a decrease in UG2Lr cell numbers in uncontaminated soil. In combination, antibiotic resistance, bioluminescence, and PCR analyses provided sensitive detection and quantitative enumeration of P. aeruginosa UG2Lr in soil.
The taste of things to come (1982)

The differential light scattering (DLS) properties of six popular cola drinks are compared (three standard and three saccharine-sweetened). Each produces a unique DLS pattern characteristic of its unique taste. The probable demise of the subjective taste test in favor of a quantiative quality control DLS measurement is proposed.
The design and development of an experimental netted radar system (2004)

In this paper we report on the development of a low-cost, four-node netted radar system operating at S-band. The system has been designed using 'commercial off the shelf' subsystems and components wherever possible. A detailed computer simulation has been implemented to provide an environment for testing design options and development of a test strategy for the completed network. This has been invaluable as the extra dimensionality of the system, uncertainty in component specification and potential variability in the synchronisation signal make design and performance prediction complex.

Developing the Effective Production Allocation Workflow Using Different Approaches for Gas Condensate Reservoir (2010)

Abstract This paper presents a practical methodology for the determination of error bounds in the oil back allocation procedure and its application to decision making in the development of a giant gas condensate reservoir in the Caspian region. The case study of allocating fluid rates to individual wells has been performed by adjustment of reservoir pressure and gas-oil ratio with time using computer aided analysis. This work describes improvements in well performance modelling and outlines the effective workflow whereby well performance can be estimated at any given period. The workflow has provided a cost-effective solution that reduces uncertainties in estimating production volumes at the well level. Well models are built using production well test data. These tests are usually performed at best on an annual basis for fields with a large number of producing wells. Therefore, the well models are nearly always out of date by a matter of months or even years, and the allocation factor associated with traditional models could be over the reasonable accuracy level. In addition to traditional models well performance software models have been developed and used. By adjusting the software models for predictable changes in reservoir pressure and gas oil ratio, the oil allocation factor errors can be reduced significantly. This methodology can also be applied to historical data to improve the production assumptions used to history match the field simulation model A comparative study of the different allocation methods and its impact to allocation factor errors and to net present values has been carried out, and confirmed the importance of correct oil reconciliation at the well level.
Roles and security in a publish/subscribe network architecture (2010)

Several publish/subscribe (pub/sub) and data-oriented networking proposals have been presented to overcome limitations of the current message- and host-centric Internet. However, security issues of these solutions have not been addressed comprehensively. In this paper we examine roles of actors comprising an inter-domain pub/sub network, together with security requirements and minimal required trust associations arising from this setting. We then introduce and analyze a security design for a clean-slate pub/sub network architecture that secures both the control and data planes. The solution addresses availability and data integrity while remaining scalable and usable.
Development of surface photochemical modification method for micropatterning of cultured cells (1995)

This article reports the development of micropatterning technology of cultured cells by precise surface regional modification via photochemical fixation of phenyl azido-derivatized polymers on polymer surfaces. Photoreactive polymers prepared in this study included poly(N,N-dimethylacrylamide-co-3-azidostyrene), bis-4-azidobenzamide-polyethylene glycol, and poly(styrene-co-3-azidostyrene). The photochemical fixation of these photoreactive polymers consisted of three steps: 1) coating of a photoreactive polymer on a material surface, 2) ultraviolet irradiation through a photomask, and 3) removal of nonreacted polymer by a solvent. Electron spectroscopy for chemical analysis and water contact angle measurement were employed for surface characterization. Two different types of regionally modified surfaces were prepared; one was a hydrophilic polymer regionally fixed on a tissue culture dish and the other was a hydrophobic polymer regionally fixed on poly(vinyl alcohol) (PVA). Photochemical surface microfabrication permits mu-order dimensional precision, which was verified by the micropatterned tissue formation of bovine aorta endothelial cells (ECs) when ECs were seeded on these surfaces. ECs adhered, spread, and confluently proliferated only on uncoated tissue culture dish surfaces or hydrophobic regions on PVA. Thus, the regionally differentiated cell adhesional regions were created by photochemically driven surface microprocessing.
End points of resuscitation: Choosing the right parameters to monitor (2002)

Determining when resuscitation is complete can be challenging, as tissue hypoperfusion can persist despite normal vital signs. This article discusses the limitations of traditional parameters used as resuscitation guidelines and describes new technologies that aid in assessing resuscitation efforts, including advances in hemodynamic monitoring and methods for obtaining global and organ-specific indexes.
Low cost multi-chip modules based on single and double sided chip-on-board modules following Jedec standard specifications (2002)

The author explains how two original designs using chip-on-board technology have been completed and pushed into production. Both are made on the same kind of modified multilayer glass epoxy. One is equipped with J lead output pins, allowing the mounting of silicon dice on both faces of the printed circuit board; the second supports dice on the top only, the bottom face being reserved for direct surface mount device (SMD) soldering carefully prepared for this purpose. Design rules, dimensions regarding Jedec standard, mounting procedures as well as qualification program and test approach are described. Considerations on the choice of dice epoxy coatings are explained. Dispensing and machining are defined to allow pick and place handling by automatic machine.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Physiological and pathological angiogenesis in the endocrine system (2002)

Formation of new blood vessels occurs in many physiological states (during development of the embryo, cycling changes of the female reproductive tract), as well as in pathological processes (such as diabetic retinopathy and wound healing). Angiogenesis has been shown to be related to tumor formation, prognosis, and response to treatment in many tumor types. Intratumoral microvessels can be related to tumor behavior or hormone secretion in different endocrine tumors. For example, invasive prolactinomas are more vascular than noninvasive adenomas; a surgical approach is more successful in macroprolactinomas with lower microvessel density. A higher number of microvessels have been found in papillary thyroid carcinomas during recurrences. A correlation between microvessel count and prognosis in papillary and medullary thyroid carcinomas has been suggested. Several stimulating and inhibiting factors involved in the regulation of angiogenesis have been identified. Among them, vascular endothelial growth factor (VEGF) has been shown to be critically involved in angiogenesis and also in the neovascularization of solid tumors. Dopamine agonists (already in clinical use for prolactinomas) have potent inhibitory actions on VEGF signaling, and thus may be a new tool in antiangiogenic therapy. Secretion of VEGF in the great majority of human pituitary adenomas is inhibited by dexamethasone. This suggests that glucocorticoids can be considered in the treatment of certain pituitary tumors. The cyclic nature of angiogenesis in the female reproductive tract indicates that stimulation or inhibition of paracrine angiogenic factors may lead to new approaches for being able to influence reproductive endocrine disorders. Experimental and clinical aspects of interactions between angiogenic factors and tumor growth of the endocrine system are also discussed.
