GPC Separation and Integrated Structural Analysis of Petroleum Heavy Ends (1970)

Abstract Three hundred grams of a Venezuelan asphalt was separated on a 70-liter GPC column in one run. The 30 cuts collected were consolidated to 7 fractions. After separating the insoluble asphaltenes from the soluble maltenes by n-pentane extraction, the maltenes were chromatographed on deactivated alumina into oil and three different resin fractions. Selected fractions were analyzed by NMR, IR, density, and elemental analysis. The experimental results were evaluated by a novel method making use of an extensive scheme of structure relations. Percentages of aromatic, naphthenic, and paraffinic carbon; number of ring systems per molecule, their average size, compactness, composition, and substitution are given explicitly or implicitly.

Evaluation of the Wind Energy Potential in the Coastal Environment of Two Enclosed Seas (2015)

The work presents a comprehensive picture of the wind energy potential in the coastal environment of the Black and the Caspian Seas. 10-year of data coming from the US National Centers for Environmental Prediction was considered as the main source. This dataset was subsequently compared with both in situ and remotely sensed measurements. The results show that the western side of the Black Sea has an enhanced wind power potential, especially in the vicinity of the Crimean Peninsula. As regards the Caspian Sea, the northeastern sector can be considered more energetic. A direct comparison of various wind parameters corresponding to the locations with higher potential in the two target areas considered was also carried out, in order to notice the similarities and the key features that could be taken into account in the development of an offshore wind project. Finally, it can be concluded that the coastal environments of the Black and the Caspian Seas can become in the near future promising locations for the wind energy extraction, as well as for the hybrid wind-wave energy farms that could play an important role also in the coastal protection.
Forum: Collaboration for Our Greater Good (2011)

In order for research to be relevant and applicable, it is important for us to remember our constituency. Our students and colleagues in the public schools may see research as something abstract and distant, but string education researchers are conducting studies in a variety of areas such as student teaching, vibrato, mentorship of first-year teachers and chamber music, to name only a few. Collaborating with our current students and public school colleagues may offer opportunities for greater understanding on both sides of this imaginary dividing line.

Adaptive Gearbox Selection Method to Improve the Performance of Industrial Robotic Arms (2017)

Abstract Robotic arms play a major role in today’s environment. Many robotic arms are used in industries, factories, and our surrounding environments. Many types of robotic arms are used for their particular purpose. Gearbox selection is very important in increasing the performance of robotic arms. Therefore, it is necessary to select the gearbox to improve the performance of robotic arms for everyday use. Thus, an efficient method is proposed to improve the performance of robotic arms for industries. This efficient method adaptively controls the gearbox to increase the performance of industrial robotic arms. The cuckoo search algorithm is an efficient method proposed to increase the performance of industrial robotic arms. By this method, we can improve the performance of industrial robotic arms and make use of these robotic arms in the modern world. The technique has been implemented in the working platform of MATLAB, and the results have been analyzed.
Information technology. Geographic information systems and public health: mapping the future (1999)

This information technology review provides thoughts about current trends and future directions for geographic information systems (GIS) technology in public health and the challenges to institutionalizing this technology as a standard part of public health planning and practice by the Year 2010. Topics include: current trends; epidemiology and GIS technology; definition; advantages of GIS technology; current limitations of GIS technology; anticipated developments in the near future; and anticipated developments in 5-10 years. Two reports of GIS mapping applications also are included: Mapping Rodent Complaints by Neil M. Casey, Jack Smith, and C. William Keck, Akron Health Department, Ohio; and Women with Localized Breast Cancer Selecting Mastectomy Treatment, Iowa, 1991-1996 by Gerard Rushton and Michele West, Department of Geography, University of Iowa. The review concludes that public health applications of GIS technology in 1999 are still in the early stages. Many challenges remain that will need to be addressed before the full potential of GIS technology can be realized for public health practice, planning, and research. One of the greatest challenges will be to incorporate epidemiologic principles and methods into the analysis to be mapped. Another major challenge will be to develop methods and procedures to assure the confidentiality of individuals and individual households. Geographic Information Systems and Public Health:
Theory of laminated piezoelectric plates for the design of distributed sensors/actuators. Part I: Governing equations and reciprocal relationships (1990)

A piezoelectric laminate theory that uses the piezoelectric phenomenon to effect distributed control and sensing of bending, torsion, shearing, shrinking, and stretching of a flexible plate has been developed. This newly developed theory is capable of modeling the electromechanical (actuating) and mechanoelectrical (sensing) behavior of a laminate. Emphasis is on the rigorous formulation of distributed piezoelectric sensors and actuators. The reciprocal relationship of the piezoelectric sensors and actuators is also unveiled. Generalized functions are introduced to disclose the physical concept of these piezoelectric sensors and actuators. It is found that the reciprocal relationship is a generic feature of all piezoelectric laminates.
Epidemiology of parasitic protozoan infections in Soay sheep (<i>Ovis aries</i>L.) on St Kilda (2006)

The feral Soay sheep (Ovis aries L.) population on Hirta, St Kilda, is host to a diverse component parasite community, but previous parasitological studies of the population have only focussed on the metazoan species. This paper reports the first epidemiological study of the protozoan species comprising Cryptosporidium parvum, Giardia duodenalis and 11 species of Eimeria in Soay sheep across 3 years of varying host population density. Prevalence and intensity of almost all species of protozoa significantly decreased with host age, with the exception of E. granulosa, which increased in prevalence with host age. The prevalence of C. parvum appeared to vary positively with host population density but that of G. duodenalis did not vary significantly with density. Most species of Eimeria showed a distinct lag in infection level following the host population crash of 2002, taking up to 2 years to decrease. Mixed Eimeria species intensity and diversity were highest in 2002, a year of low host density. Parasite diversity decreased with host age and was higher in males. There were 5 positive pair-wise associations between protozoa species in terms of prevalence. The results of this study highlight the potential for protozoal infection to shape the evolution of parasite resistance in wild host populations harbouring diverse parasite species.
Effect of Antimony doping on the structure, electrical and optical properties of Tin Oxide thin films. (2001)

In this work Antimony doped Tin Oxide thin films have been deposited on Corning 7059 glass, using Electron Beam Vacuum Evaporation. The optimum concentration was 5% of antimony, in the source pellet, with respect to tin. The prepared films have been characterized by x-ray diffraction, electrical and optical measurements. 2 were used for the films, which had the Vander Pau geometry (with Al contacts). The optical transmission (T%) was recorded using a UV-Visible double-beam spectrophotometer (UV-265 Shimadza) between 250-900 nm wavelength range. The structure of the films was studied by an x-ray diffraction technique using Co-Kα1 radiation, while the composition of the conductive films was detected by an energy dispersive spectrometer in an SEM. 3. RESULTS AND DISCUSION The comparison between the chemical composition of source pellet and the deposited film is shown in Fig. 1. It is observed that the percentage of the Sn in the films was slightly lower than the source pellet, but the variation was almost linear.
EXPLORING MANAGED NAND MEDIA ENDURANCE (2010)

Flash memory can be found in media players, cameras, cell phones and portable storage. These consumer items have universally compatible storage devices. However, what is their longevity and what is the long-term data retention reliability? This thesis will explore and attempt to answer these questions. Predicting accurate endurance ratings and long-term storage reliability is problematic; a storage card in a cell phone will simply wear differently if used for personal computer backup. Advertised longevity ratings can also be ambiguous, specified in a number of years of ‘typical’ and ‘average’ use. This thesis begins by exploring the operation of flash technology used in managed NAND devices. Operational and hidden byproducts of controlling flash memory were identified then directly observed on a sampled MultiMediaCard (MMC) card. The collected data was graphed to calculate the life span of the product for several synthetic data transfer categories. Combined with the total storage capacity, the factors used in longevity calculations are shown to be dependent upon the transfer method. To answer the original question, a hypothetical camera file storage usage model was contrasted against measured wear data to calculate longevity. When changing the addressing randomness of writing data to fifty percent of total transfers, the 10-year advertised longevity was shown diminished by half. This demonstrated how data storage randomness of the usage model influences device longevity.
Deactivation of<i>Escherichia coli</i>by the plasma needle (2005)

In this paper we present a parameter study on deactivation of Escherichia coli (E. coli) by means of a non-thermal plasma (plasma needle). The plasma needle is a small-sized (1 mm) atmospheric glow sustained by radio-frequency excitation. This plasma will be used to disinfect heat-sensitive objects; one of the intended applications is in vivo deactivation of dental bacteria: destruction of plaque and treatment of caries. We use E. coli films plated on agar dishes as a model system to optimize the conditions for bacterial destruction. Plasma power, treatment time and needle-to-sample distance are varied. Plasma treatment of E. coli films results in formation of a bacteria-free void with a size up to 12 mm. 10/sup 4/-10/sup 5/ colony forming units are already destroyed after 10 s of treatment. Prolongation of treatment time and usage of high powers do not significantly improve the destruction efficiency: short exposure at low plasma power is sufficient. Furthermore, we study the effects of temperature increase on the survival of E. coli and compare it with thermal effects of the plasma. The population of E. coli heated in a warm water bath starts to decrease at temperatures above 40 degrees C. Sample temperature during plasma treatment has been monitored. The temperature can reach up to 60 degrees C at high plasma powers and short needle-to-sample distances. However, thermal effects cannot account for bacterial destruction at low power conditions. For safe and efficient in vivo disinfection, the sample temperature should be kept low. Thus, plasma power and treatment time should not exceed 150 mW and 60 s, respectively
Mutations of Tyrosine 537 in the Human Estrogen Receptor-α Selectively Alter the Receptor's Affinity for Estradiol and the Kinetics of the Interaction (2002)

Mutation of tyrosine 537 (Y537) of the human estrogen receptor-alpha (hERalpha) produces receptors having a range of constitutive activity, which suggests that this residue modulates the conformational changes of the receptor. We investigated the effect of several mutations at this position, to phenylalanine (Y537F), to serine (Y537S), and to glutamic acid (Y537E), on the hormone-binding properties of the receptor. The affinities of the wt, the Y537F mutant, and the Y537S mutant for estradiol were similar: K(a) = 2.2 +/- 0.2, 3.9 +/- 0.5, and 2.8 +/- 0.4 nM(-1), respectively. By contrast, the affinity of the Y537E mutant for estradiol was reduced 10-fold, K(a) = 0.2 +/- 0.1 nM(-1). All proteins bound [(3)H]estradiol with a positive cooperative mechanism (n(H) = 1.7-1.9), indicating they can form dimers. The wt receptor and the Y537S and Y537E mutants exhibited biphasic dissociation kinetics, which is also indicative of dimerization. Surprisingly, the half-lives of the slow component of the wt and the Y537E mutant were indistinguishable, 118 +/- 3.4 and 122 +/- 4.5 min, respectively, even though the affinity of the Y537E mutant for hormone was reduced 10-fold. The half-life of the slow component of the Y537S mutant was reduced to 96.5 +/- 3.8 min. Molecular models were constructed and compared to identify changes in the structure that correlate with the observed effects on hormone binding. Local alterations in hydrogen bonding, the position of side chains, and the position of the peptide backbone were observed. Taken together, these results show that mutations at Y537 selectively alter the affinity and kinetics of hormone binding to the receptor, and are consistent with the idea that the estradiol-estrogen receptor interaction can follow more than one pathway.
Java and JDBC: tools supporting data-centric business application development (2002)

Software porting, maintenance, distribution and installation form the bulk of application deployment costs. These high costs have been substantially exacerbated by the move to client server computing. No longer can an application be installed on one system for use by the entire user community. Now it must be installed on all desktops in the enterprise and, at most companies, this will be mean that the software must be ported to and tested on Windows 3.1, Macintosh, Windows95, Windows NT, and often a variety of UNIX systems. The trend towards making business data available to both internal and external users across intranets and the Internet transforms an expensive problem into a completely intractable one. To further complicate the matter, there is an emerging trend in many application domains to move from 2 dimensional windowed user interfaces to high information bandwidth 3 dimensional data visualization and virtual reality systems. These applications are either very difficult or impossible to write using standard GUI builders, generators, or the current breed of portable GUI class libraries. We propose a new architecture for data visualization, discovery, and delivery and argue that the existing development model, and the tools supporting that model, are unaffordable and don't scale to Internet scope delivery numbers.

New initial position detection technique for three-phase brushless DC motor without position and current sensors (2003)

This paper presents a new detection technique of initial position for a three-phase brushless DC motor which does not require any current and position sensors, and thereby significantly reduces the cost. The fundamental principle of the technique is to determine the initial position of the permanent magnet by the time periods of discharge of stator windings, which are excited before discharge. As compared to previous approaches, the presented technique does not cause any rotation during detection, and it is therefore very promising for particular kinds of applications, which do not allow the motor to rotate potentially in the wrong direction during initial position detection, e.g., electrical vehicles. As compared to earlier techniques, the presented technique dramatically simplifies the detection procedures and cost. Experimental results derived from a field-programmable gate-array-based control system are presented to demonstrate the feasibility of the presented technique.
Diversity-oriented Multimodal and Interactive Information Retrieval (2016)

Information retrieval methods, especially considering multimedia data, have evolved towards the integration of multiple sources of evidence in the analysis of the relevance of the items considering a given user search task. In this context, for attenuating the semantic gap between low-level features extracted from the content of the digital objects and high-level semantic concepts (objects, categories, etc.) and making the systems adaptive to different user needs, interactive models have brought the user closer to the retrieval loop allowing user-system interaction mainly through implicit or explicit relevance feedback. Analogously, diversity promotion has emerged as an alternative for tackling ambiguous or underspecified queries. Additionally, several works have addressed the issue of minimizing the required user effort on providing relevance assessments while keeping an acceptable overall effectiveness This thesis discusses, proposes, and experimentally analyzes multimodal and interactive diversity-oriented information retrieval methods. This work, comprehensively covers the interactive information retrieval literature and also discusses about recent advances, the great research challenges, and promising research opportunities. We have proposed and evaluated two relevancediversity trade-off enhancement work-flows, which integrate multiple information from images, such as: visual features, textual metadata, geographic information, and user credibility descriptors. In turn, as an integration of interactive retrieval and diversity promotion techniques, for maximizing the coverage of multiple query interpretations/aspects and speeding up the information transfer between the user and the system, we have proposed and evaluated a multimodal online learning-to-rank method trained with relevance feedback over diversified results Our experimental analysis shows that the joint usage of multiple information sources positively impacted the relevance-diversity balancing algorithms. Our results also suggest that the integration of multimodal-relevance-based filtering and reranking is effective on improving result relevance and also boosts diversity promotion methods. Beyond it, with a thorough experimental analysis we have investigated several research questions related to the possibility of improving result diversity and keeping or even improving relevance in interactive search sessions. Moreover, we analyze how much the diversification effort affects overall search session results and how different diversification approaches behave for the different data modalities. By analyzing the overall and per feedback iteration effectiveness, we show that introducing diversity may harm initial results whereas it significantly enhances the overall session effectiveness not only considering the relevance and diversity, but also how early the user is exposed to the same amount of relevant items and diversity
Validity of pulsatility and resistance indices in classification of adnexal tumors with transvaginal color Doppler ultrasound (1992)

Transvaginal pulsed color Doppler ultrasound was used to examine 72 patients with a pelvic mass preoperatively. Tumor morphology was assessed, prominent areas of vascularization within the tumor were observed and the pulsatility index and the resistance index of tumor and uterine arteries were measured. Flow velocity waveforms with low pulsatility are considered to reflect neovascularization. The ultrasound diagnoses were compared with histopathological or cytological diagnoses. There were 61 benign, eight malignant and three borderline cases. In 75% of the malignant and 23% of the benign tumors, an intratumoral flow with a low pulsatility was detectable. The mean pulsatility index of tumor blood vessels was 1.2 in benign, 0.7 in malignant and 0.6 in borderline neoplasms. The corresponding mean resistance index values were 0.6, 0.5 and 0.5. The differences were not significant and the overlap between the malignant and benign lesions was large. The pulsatility index and resistance index of uterine arteries were significantly decreased in malignant tumors. The results show that, using a cut-off resistance index value of 0.6, the sensitivity and specificity of color Doppler in the detection of malignant and potentially malignant tumors were 82% and 72%, respectively. However, a practical cut-off level for either pulsatility or resistance indices, that could assist in differentiating between malignant or benign lesions, does not seem to exist.
