Integrating cloud service deployment automation with software-defined environments (2014)

The last decade has seen a deluge of technology and services related to cloud-computing. The idea of traditional IT infrastructure has been usurped by a rush to move all services to a cloud infrastructure and to implement them in a cloud-native way. A cloud infrastructure is unlike a conventional infrastructure in that, it is implemented as a Software-Defined Environment (SDE) which abstracts and virtualises the underlying physical resources. It manages physical resources and provides virtual resources that process, manage, store, create networks and provision services. But while the concept of a virtual data center as played out by an SDE seems ideal, the issues it brings in implementation are quite a few. For one, deployment and management of services on such a large scale is difficult. It is also subject to human efficiency and error. So, new levels of tracking and automation have to be explored in parallel to support and sustain the cloud-computing phenomenon. Several configuration management and orchestration tools have been developed over years, to fulfill the need of automated deployment and management. TOSCA is one of such that provides a specification which empowers this goal by using a metamodel. It defines implementation artifacts that encapsulate functionality of external services to use them during deployment. An open-source container called OpenTOSCA, is under development at the University of Stuttgart. This framework can process the TOSCA specification. In this thesis, OpenStack has been employed as the cloud infrastructure provider. To achieve our goal, an implementation artifact for the relevant OpenStack components has to be developed in concept and implementation. In order to create useful implementation artifacts an appropriate level of abstraction has to be introduced between the low-level OpenStack API and the services that the implementation artifact provides. Accordingly, a TOSCA artifact is designed and implemented as a web service and packaged in a container file, called CSAR. This file, when processed by the OpenTOSCA container, causes the automated provisioning of a server on OpenStack. To evaluate the nature of the implementation artifact, the web service is hosted on the local machine and tests are performed to check for correct implementation of service endpoints. The results of these invocations are later presented.
A Novel Approach to In Situ Diffractometry of Intercalation Materials: The EDXD Technique Preliminary Results on LiNi[sub 0.8]Co[sub 0.2]O[sub 2] (1999)

The application of the energy dispersive X‐ray diffraction (EDXD) technique to in situ structural measurements on battery materials is shown for the first time. EDXD may present a promising alternative for this kind of measurement to the traditional diffractometric technique, even when the synchrotron radiation is used. The merits and drawbacks of this method are discussed, with particular attention to the solution of the X‐ray absorption problem that, reducing the signal intensity, imposes the use of specifically designed cells. Finally, preliminary results obtained in the study of a typical commercial cathodic material for batteries are reported. ©2000 The Electrochemical Society
Interactive feature extraction for a form feature conversion system (1997)

A feature-based CAD system must support multiple feature representations in the concurrent engineering environment in which multiple engineering groups work on a same product simultaneously. Users must be able to define customized features interactively, for different users need different feature sets. On the other hand, to share high-level information stored in features among different engineering groups, the features must be standardized to be compatible among highly customized feature sets. To solve the two conflicting requirements, a feature conversion system architecture including an interactive feature extraction module has been developed and implemented. Sharing the same basis of fundamental features, multiple feature representations can be maintained in the system. In this paper, an intermediate feature representation based on B-rep entities will be addressed for a feature conversion architecture. For the one-to-one mapping cases, a feature shape code matching mechanism is used, and a constraint-based feature extraction method is advocated for the feature conversion problem.
System performance of semiconductor laser amplifier detectors (1989)

A spider-like robot that climbs vertically in ducts or pipes (2002)

Different implementations of remote controlled robots with wheels or stepping mechanisms are in use that can inspect and repair the interior of a pipe or duct. However, autonomous locomotion in complex shaped hollows with corners, steps and branches remains a major challenge. This paper describes a robot with articulated legs that opens up the possibility of servicing complex pipe systems. To solve the pipe climbing task autonomously, the robot has a hierarchical control architecture with reflexive and reactive behaviour. Experiments were carried out in a 2D simulation as well as with an eight-legged robot test-bed. The experiments show the physical feasibility of such a robot, and that it is possible to achieve a robust, safe and powerful operation using reflexive and reactive behaviour.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Pulsed microwave discharge: a very efficient H atom source (1994)

We describe a very efficient source of H atoms generated by a : low-pressure (1 Torr) pulsed microwave discharge (2.45 GHz). We show that the low mean microwave power density applied in pulsed discharge limits considerably the heating of the discharge tube wall, and hence, the loss of H atoms by wall recombination. The H atom molar ratio, measured by actinometry, increases from 30% in continuous power to nearly 100% in pulsed power, for the same instantaneous power. We present a comparison between continuous and pulsed power, both for electron density (and discharge balance parameters) and for H atom density.
Implementation on Landsat Data of a Simple Cloud-Mask Algorithm Developed for MODIS Land Bands (2011)

This letter assesses the performance on Landsat-7 images of a modified version of a cloud-masking algorithm originally developed for clear-sky compositing of Moderate Resolution Imaging Spectroradiometer images at northern midlatitudes. While most historical Landsat data include measurements at thermal wavelengths and such measurements are also planned for the next mission, thermal tests are not included in the suggested algorithm in order to maintain greater versatility and ease of use. The evaluation of the masking algorithm takes advantage of the availability of manual (visual) cloud masks developed at the U.S. Geological Survey for a collection of Landsat scenes. As part of the evaluation, we also include the automated cloud cover assessment (ACCA) algorithm which does include thermal tests and is used operationally by the Landsat-7 mission to provide scene cloud fractions but no cloud masks. We show that the proposed algorithm performs on par with the ACCA both in terms of scene cloud fraction and pixel-level mask agreement. Specifically, the algorithm gives an error of 0.8% for the scene cloud fraction of 156 scenes and a root-mean-square error of 7.1%, while it agrees with the manual mask for 93.1% of the pixels. These performance indicators are very similar to those of the ACCA (1.2%, 7.1%, and 93.7%).
Mouse model for colonization and disease caused by enterohemorrhagic Escherichia coli O157:H7 (1990)

Enterohemorrhagic Escherichia coli O157:H7 isolates produce Shiga-like toxins and carry a 60-megadalton plasmid which encodes an adhesin for Henle 407 intestinal cells. A streptomycin-treated mouse model was used to compare the intestinal colonizing capacity of E. coli O157:H7 strain 933 with that of its 60-megadalton plasmid-cured derivative, strain 933cu. When fed individually to mice, both 933 and 933cu maintained a stable number of organisms per gram of feces, and the greatest numbers of 933 or 933cu were isolated from cecal and proximal colonic epithelial cells. When 933 and 933cu were simultaneously fed to mice, 933cu was unable to maintain a stable level of colonization in about two-thirds of the mice tested. However, in one-third of the mice, the number of 933cu in feces began to increase rapidly until a stable level of co-colonization with 933 was attained. The isolate from these mice, 933cu-rev, was excreted in high numbers when fed alone to mice and was found on epithelial cells throughout the entire large bowel and distal small intestine. Moreover, 933cu-rev grew in mucus from all segments of the intestine and at higher levels than strain 933 or 933cu. Only mice fed strain 933cu-rev died. Histopathological studies confirmed that mice fed 933cu-rev died from bilateral renal cortical tubular necrosis consistent with toxic insult, perhaps due to Shiga-like toxins. The virulence of 933cu-rev may reflect its ability to grow well in mucus and colonize the small as well as large bowel.
Noncoherent block demodulation of PSK (2002)

Noncoherent demodulation of phase shift keying (PSK) over a multisymbol observation interval is considered. It is shown that by performing noncoherent demodulation over an increased observation interval, the performance approaches that of coherent PSK. This block demodulation technique of PSK is a natural generalization of differentially coherent detection, and yields improved signal-to-noise ratio (SNR) performance. Some structural properties of this demodulation technique are explored, and its performance is analyzed by using the union-bound.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A Generic Graph Transformation, Visualisation, and Editing Framework in Haskell (2009)

Graph transformation, visualisation, and editing are useful in many contexts, and require domain-specific customisation. However, many general-purpose graph solutions lack customisability in at least one area.

We present a framework that aims to allow polished customisation in all three areas, using the powerful abstraction capabilities of the pure functional programming language Haskell. The design of our framework integrates and adapts time-tested object-oriented designs into a purely functional framework, and uses current user-interface libraries (GTK+ and Cairo) to achieve polished presentation.

Our framework provides both a low-level programmed approach to graph transformation, and, on top of this, high-level approaches including SPO and DPO, which are implemented using categorical abstractions in an intuitive and flexible way.
Electrical properties of BC2N thin films prepared by chemical vapor deposition (1995)

The electrical properties of BC2N thin films have been investigated in terms of the temperature dependence of the resistivity and Hall effect measurements. The BC2N thin films were prepared by chemical vapor deposition from acetonitrile and boron trichloride on polycrystalline Ni and quartz substrates. The experimental results indicated that the BC2N films were p-type semiconductors on both substrates, with acceptor levels between 7.5 and 23 meV relative to the valence band. The hole mobility on Ni substrates was one order of magnitude higher than that on the quartz substrates, suggesting that the thin film quality is better on Ni substrates than on quartz substrates.
Review article: drug‐induced liver injury in clinical practice (2010)

Drug-induced liver injury remains a diagnostic challenge. Multicentre studies and international collaborative work with well-characterized patients will increase our understanding of liver injury associated with drugs. New therapies for acute liver failure resulting from drugs are needed.
Evolutionary stability in repeated games played by finite automata (1991)

We consider a game in which “meta-players” choose finite automata to play a repeated stage game. Meta-players' utilities are lexicographic, first increasing in the (limit-of-the-means) payoffs of the repeated game and second decreasing in the number of states in their automaton. We examine the outcomes in this game which satisfy a version of evolutionary stability that has been modified to permit existence. We find that such automata must be efficient, in that they must maximize the sum of the (limit-of-the-means) payoffs from the repeated game.
Mutations Abrogating the RNase Activity in Glycoprotein E<sup>rns</sup>of the Pestivirus Classical Swine Fever Virus Lead to Virus Attenuation (1999)

Classical swine fever (CSF) is a severe hemorrhagic disease of swine caused by the pestivirus CSF virus (CSFV). Amino acid exchanges or deletions introduced by site-directed mutagenesis into the putative active site of the RNase residing in the glycoprotein E(rns) of CSFV abolished the enzymatic activity of this protein, as demonstrated with an RNase test suitable for detection of the enzymatic activity in crude cell extracts. Incorporation of the altered sequences into an infectious CSFV clone resulted in recovery of viable viruses upon RNA transfection, except for a variant displaying a deletion of the histidine codon at position 297 of the long open reading frame. These RNase-negative virus mutants displayed growth characteristics in tissue culture that were undistinguishable from wild-type virus and were stable for at least seven passages. In contrast to animals inoculated with an RNase-positive control virus, infection of piglets with an RNase-negative mutant containing a deletion of the histidine codon 346 of the open reading frame did not lead to CSF. Neither fever nor extended viremia could be detected. Animals infected with this mutant did not show decrease of peripheral B cells, a characteristic feature of CSF in swine. Animal experiments with four other mutants with either exchanges of codons 297 or 346 or double exchanges of both codons 297 and 346 showed that all these RNase-negative mutants were attenuated. All viruses with mutations affecting codon 346 were completely apathogenic, whereas those containing only changes of codon 297 consistently induced clinical symptoms for several days, followed by sudden recovery. Analyses of reisolated viruses gave no indication for the presence of revertants in the infected animals.
Responses of Electric-Field Probes Near a Cylindrical Model of the Human Body (1985)

A theoretical and experimental study on the response of an E-field probe near a cylindrical model of the human body has been conducted. The body is simulated with a long cylindrical dielectric shell filled with saline water, and a single E-field probe oriented in various directions, or an orthogonal probe is heated near its surface. The model with the probe is illuminated by a TE or TM plane EM wave. The response of the probe was found to be strongly dependent on the probe location with respect to the direction of the incident EM wave, the probe separation from the model surface, the probe orientation and the polarization of the incident EM wave. The effect due to the dielectric shell on the probe response, with and without the presence of saline water, was carefully investigated. In all cases, the agreement between theory and experiment was found to be very good.

An improved two-stage current transformer (1991)

A novel design of magnetic cores and windings of a two-stage current transformer which considerably improves its linearity and accuracy for a given load is discussed. The equations which describe the operation of the transformer are given, and formulas for the calculation of the error are derived. A practical technique for unloading the second core and bringing its magnetic flux near zero is given. Experimental results show that with relatively small cores and a small amount of copper an accuracy better then 20 ppm and 20 mu rd is achieved. The device is passive, with no electronically enhanced technique being implemented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Active SSD design for energy-efficiency improvement of web-scale data analysis (2013)

NAND flash based solid state drives (SSDs) have been widely adopted as storage devices in modern data centers to provide high performance I/O services. Recently, researchers proposed several schemes to improve energy efficiency of the system by off-loading specific computation tasks from generic processors to local processing elements in SSD controllers. However, it is inefficient to directly apply these approaches to the web-scale data analysis system equipped with modern SSDs using FPGA based controllers. More important, the design schemess proposed in prior work cannot work with our target system. In order to overcome the limitation, we present our Active SSD design, considering unique features of computation tasks in web-scale data analysis. In addition, we address an important issue about interference between normal data processing and local computation in Active SSDs. The detailed architecture of our Active SSD is described, and a prototype is implemented. Moreover, the modification to the whole system is also introduced to enable the Active SSD. Experimental results based on real applications show that the energy efficiency can be significantly improved with our design.
FILLING HOLES IN TRIANGULAR MESHES USING DIGITAL IMAGES BY CURVE UNFOLDING (2010)

We propose a novel approach to automatically fill holes in triangulated models. Each hole is filled using a minimum energy surface that is obtained in three steps. First, we unfold the hole boundary onto a plane using energy minimization. Second, we triangulate the unfolded hole using a constrained Delaunay triangulation. Third, we embed the triangular mesh as a minimum energy surface in ℝ3. When embedding the triangular mesh, any energy function can be used to estimate the missing data. We use a variational multi-view approach to estimate the missing data. The running time of the method depends primarily on the size of the hole boundary and not on the size of the model, thereby making the method applicable to large models. Our experiments demonstrate the applicability of the algorithm to the problem of filling holes bounded by highly curved boundaries in large models.

Activating Mutations in the <i>KCNJ11</i> Gene Encoding the ATP-Sensitive K+ Channel Subunit Kir6.2 Are Rare in Clinically Defined Type 1 Diabetes Diagnosed Before 2 Years (2004)

We have recently shown that permanent neonatal diabetes can be caused by activating mutations in KCNJ11 that encode the Kir6.2 subunit of the beta-cell ATP-sensitive K(+) channel. Some of these patients were diagnosed after 3 months of age and presented with ketoacidosis and marked hyperglycemia, which could have been diagnosed as type 1 diabetes. We hypothesized that KCNJ11 mutations could present clinically as type 1 diabetes. We screened the KCNJ11 gene for mutations in 77 U.K. type 1 diabetic subjects diagnosed under the age of 2 years. One patient was found to be heterozygous for the missense mutation R201C. She had low birth weight, was diagnosed at 5 weeks, and did not have a high risk predisposing HLA genotype. A novel variant, R176C, was identified in one diabetic subject but did not cosegregate with diabetes within the family. In conclusion, we have shown that heterozygous activating mutations in the KCNJ11 gene are a rare cause of clinically defined type 1 diabetes diagnosed before 2 years. Although activating KCNJ11 mutations are rare in patients diagnosed with type 1 diabetes, the identification of a KCNJ11 mutation may have important treatment implications.
Communication Protocols for Embedded Systems (2018)

In this article, we will first discuss the special considerations for networking real-time embedded systems. Then, we describe several media access protocols that demonstrate fundamentally different ways of accessing the shared medium. The protocols we discuss are: Connection Oriented Protocols, Polling, Time Division Multiple Access (TDMA), Token Ring, Token Bus, Binary Countdown, Carrier Sense Multiple Access with Collision Detection (CSMA/CD), and Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). For each of these protocols, we will evaluate the strengths and weaknesses against the special considerations. We conclude the article by presenting a protocol tradeoff chart which will enable you the select a protocol to fit your needs. While no protocol is perfect for all purposes, we think that a variation of CSMA/CA offers the most versatility for many embedded systems.
