The Computation of Adjacent Blade-Row Effects in a 1.5 Stage Axial Flow Turbine (1997)

This paper deals with the numerical simulation of flow through a 1.5 stage axial flow turbine. The 3-row configuration has been experimentally investigated at the University of Aachen where measurements behind the first vane, the first stage and the full configuration were taken. These measurements allow single blade row computations, to the measured boundary conditions taken from complete engine experiments, or full multistage simulations. The results are openly available inside the framework of ERCOFTAC 1996. There are two separate but interrelated parts to the paper. Firstly, two significantly different Navier-Stokes codes are used to predict the flow around the first vane and the first rotor, both running in isolation. This is used to engender confidence in the code that is subsequently used to model the multiple bladerow tests, the other code is currently only suitable for a single blade row. Secondly, the 1.5 stage results are compared to the experimental data and promote discussion of surrounding blade row effects on multistage solutions.
Experimental Fatigue Evaluation of Aluminum Brazed Plate Fin Heat Exchangers (2013)

For the verification of a finite element based calculation procedure for the strength and fatigue design of aluminum brazed Plate Fin Heat Exchangers (PFHE) an extensive experimental investigation program was planned and executed. In the first step high temperature loadings as single events were applied to the PFHEs to recognize, whether damage (a leak) can be produced by a severe single loading. After various tests on different geometries the investigations were enlarged to thermal cycling tests on small PFHEs until leaks were detected. The tests were executed with three blocks in parallel to cover a statistical influence and the tests were repeated with three new blocks under identical conditions. All six blocks gave nearly the same number of load cycles until first detection of leaks. In addition three blocks of the same geometry were loaded with lower thermal stress, giving higher load cycle numbers until a leak occurred. The experimentally determined cycle numbers were compared to calculated cycle numbers out of the finite element modeling and showed very good agreement. Those tests and comparisons are a strong basis for fatigue and lifetime considerations on large scale PFHEs in the process industry.
Research on intrusion detection rules based on XML in distributed IDS (2008)

This paper describes the design and research of intrusion detection rules in the distributed intrusion detection system which is based on agent. The hierarchical framework model based on intelligent agents is proved in the distribute intrusion system. The model involves three kinds of intelligent agents: A type agent, B type agent and C type agent which have different task. The definition and analysis of intrusion rules in the agent is discussed. This article also studies how to use the XML to design the system data and intrusion detection rules. The definition and transportation of four kings of data called XML protocol data, XML control information, XML intrusion detection rules and XML intrusion response in the agent is presented. The IAP and SSL are used to solve the safety of XML data transported between two agents in the system.
Gallophosphonates Containing Alkali Metal Ions. 2.1 Synthesis and Structure of Gallophosphonates Incorporating Na+ and K+ Ions (1998)

The reactions between t-BuP(O)(OH)(2) and equimolar quantities of MGaMe(4) (M = Na, K) yield ionic and alkali metal containing molecular gallophosphonates [Na(4)(&mgr;(2)-OH(2))(2)(THF)(2)][(Me(2)GaO(3)PBu-t)(2)](2).2THF (2) and [K(THF)(6)][K(5)(THF)(2){(Me(2)GaO(3)PBu-t)(2)}(3)] (3), respectively. Compounds 2 and 3are soluble in common organic solvents and have been characterized by means of analytical and spectroscopic techniques, as well as by single-crystal X-ray diffraction studies. These compounds represent the rare examples of molecular ionic phosphonate cages which contain coordinated Na(+) or K(+) ions. Compound 2 is constructed from two eight-membered Ga(2)O(4)P(2) gallium phosphonate rings which sandwich a central Na(4)(H(2)O)(2) unit. In the case of 3, three eight-membered Ga(2)O(4)P(2) gallium phosphonate units envelope an aggregated K(5) core which exists in the form of a trigonal-bipyramidal polyhedron. The Na(+) and K(+) ions in 2 and 3 are also coordinated by the endocyclic oxygen atoms of the eight-membered gallophosphonate crowns, apart from the regular exocyclic P-O coordination. Unlike the lithium gallophosphonate [Li(4)(THF)(4)][{(MeGaO(3)PBu-t)(3)(&mgr;(3)-O(2))}(2)] (1), compounds 2 and 3 do not undergo any clean cage conversion reaction in the presence of 15-crown-5 and 18-crown-6, respectively.

Macaroons: Cookies with Contextual Caveats for Decentralized Authorization in the Cloud (2014)

Controlled sharing is fundamental to distributed systems; yet, on the Web, and in the Cloud, sharing is still based on rudimentary mechanisms. More flexible, decentralized cryptographic authorization credentials have not been adopted, largely because their mechanisms have not been incrementally deployable, simple enough, or efficient enough to implement across the relevant systems and devices. We introduce macaroons: flexible authorization credentials for Cloud services that support decentralized delegation between principals. Macaroons are based on a construction that uses nested, chained MACs (e.g., HMACs (42)) in a manner that is highly efficient, easy to deploy, and widely applicable. Although macaroons are bearer credentials, like cookies on the Web, macaroons embed caveats that attenuate and contextually confine when, where, by who, and for what purpose a target service should authorize requests. We describe macaroons and motivate their design, compare them to other credential systems such as cookies and SPKI/SDSI (14), evaluate and measure a prototype, and discuss practical security and protocol implementation considerations. We also formalize macaroons in a variant of authorization logic, and consider their use to strengthen existing mechanisms, such as OAuth2 (17), for more fine-grained authorization in the Cloud.
Conditional transactions: a model of computation for active databases (2002)

A transaction model for active databases is introduced. Concurrent execution of rules needs to be carefully managed to ensure consistent semantics. It is shown that serializability is not always sufficient for correctness. A new criterion, conditional conflict serializability (CCS) is developed and shown to ensure the desired correctness. A graph-based scheduler for it is presented. Practical schedulers should also be recoverable, which the graph-based scheduler is not. The authors prove that conventional two-phase locking also achieves CCS, and can thus be used in practice.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Ca2+- and Myosin Phosphorylation–independent Relaxation by Halothane in K+-depolarized Rat Mesenteric Arteries (2003)

In high K+-depolarized vascular smooth muscle, halothane relaxation is largely mediated by a Ca2+ and MLC phosphorylation desensitizing effect. These results suggest that the relaxing action of halothane is independent of the classic Ca2+-induced myosin phosphorylation contraction mechanism.
Series Connection of Supercapacitors: Comparative Study of Solutions for the Active equalization of the Voltages (2002)

Because of their low voltage level, supercapacitors need arrangement with series connection in order to obtain voltage levels from few dozen to few hunderd of volts. As for batteries, devices have then to be defined to balance the voltages across each series connected components. This paper present the problematic of voltage sharing in a series connection of supercapacitors. It is generally described the way the balancing can be obtained easier with a coherent arrangement of the supercapacitors in their tank. Then, the main solutions for sharing the voltages with active devices are presented, detailed and compared, using a global modeling approach.
Adaptive subthreshold timing-error detection 8 bit microcontroller in 65 nm CMOS (2012)

Subthreshold voltage operation enables digital systems to operate at ultra-low energy levels. However, as the voltage is reduced into subthreshold, the required safety margins become unrealistically large due to exponential dependencies. These margins can be addressed in a system by sensors, replica-path circuits, or timing error detection (TED). Each of these methods require additional energy overhead. TED is the only method that accounts for both global and local variations. This paper presents the first TED 8 bit microcontroller that is able to operate in subthreshold. The microcontroller uses adaptable EDS circuits to adjust to system-level constraints. It is built in 65 nm CMOS, uses 10.42 pJ/instruction, occupies an area of 50,200 μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , and operates down to 300 mV.
A hypothesis on membranous proteins specialized in lateral transport (1975)

The majority of membranous proteins represents enzymes catalyzing the metabolic steps that are localized inside membranes or on their surface. Besides, in membranes there are found proteins functioning as transmembrane carriers of different components, such as ions, metabolites, electrons, protons, hydrogen atoms etc.
Characterization and comparison of Australian human spotted fever group rickettsiae (1992)

The microbiological and molecular characteristics of the rickettsiae isolated from humans with Queensland tick typhus (QTT) caused by Rickettsia australis and the recently described Flinders Island spotted fever (FISF) were compared. Clinically and serologically, the diseases are similar. Cell culture reveals differences in the plaque-forming abilities of the isolates. Characterization of the gene encoding the genus-specific 17-kDa antigen of R. australis revealed a unique nucleotide sequence unlike those of the FISF isolate and Rickettsia rickettsii. Southern blot analysis of rickettsial DNA from the isolates with a 17-kDa-antigen gene probe revealed the presence of this gene in all isolates but no difference in banding patterns. When a probe for the rRNA genes was used, clear differences in banding patterns of isolates from patients with QTT and FISF were revealed. Thus, the rickettsiae isolated from patients with FISF differ from those from patients with QTT and may represent a new rickettsial species.
Industrial Design to Rapid Mold Making for Accelerated Time-to-Market of Consumer Electronic Products (1999)

Abstract The demand for quick time-to-market and the short product life cycle of consumer electronics are now pushing the development time for these products even shorter. The success of a rapid product development requires careful considerations of product markets, production needs, and available design and fabrication resources at the early development stage, and a seamlessly integrated design to fabrication environment for rapid product realization. In this paper, through a case study on the prototyping production of a finger-print recognition device, we illustrate a rapid product development through an integrated CAD/CAM environment. Rapid production of an accurate aluminum mold for 200 prototypes is highlighted. The result was a product prototype delivered within a short period of development time according to the proposed schedule. Time analysis of the entire development process was provided, and some potential improvements based on the analysis were also identified for future development of similar products.

Synthetic 2D LIDAR for precise vehicle localization in 3D urban environment (2013)

This paper presents a precise localization algorithm for vehicles in 3D urban environment with only one 2D LIDAR and odometry information. A novel idea of synthetic 2D LIDAR is proposed to solve the localization problem on a virtual 2D plane. A Monte Carlo Localization scheme is adopted for vehicle position estimation, based on synthetic LIDAR measurements and odometry information. The accuracy and robustness of the proposed algorithm are demonstrated by performing real time localization in a 1.5 km driving test around the NUS campus area.

A comparison of carepartner and patient experiences with hospital care. (2000)

Although family members and othercarepartnersplay an important role in the careand support of patients during and afterhospitalization, little attention has been paid toevaluating their experience with hospital systems,or incorporating their perspectives into qualityimprovement efforts.We conducted a nationwide telephone surveyof 1,800 recently discharged patients and theircarepartners regarding their hospital experience.We summarized and compared carepartner andpatient responses to questions regarding sixdomains of care. We also compared responses toindividual survey items to identify specificproblems that carepartners were more likely toreport.Carepartners reported problems more
High-order continuous-time incremental &#x03A3;&#x0394; ADC for multi-channel applications (2011)

A novel high-order single-loop incremental sigma- delta ADC for multi-channel applications is proposed. High- order continuous-time architectures are explored using a 3rd order single-bit modulator as a test-case. The performance of the proposed architecture, taking into account critical non-idealities, is analyzed and its advantages and issues are discussed. Behavioral simulations show a key advantage regarding the integrators' gain-bandwidth requirement of the proposed ADC compared to discrete-time counterparts. This advantage leads to possible low power solutions for multi-channel applications.
Multi-User ARQ (2006)

This paper presents a novel ARQ scheme for multiple unicast flows in a multi-user system, which enhances the aggregate throughput efficiency. The core idea is to exploit knowledge of previously overheard packets by unintended users, and perform wise selection and joint encoding of any retransmitted information. Intended users may decode the jointly encoded packet by exploiting the previously overheard packets. It is found that the throughput efficiency in a K-user system approaches, the fairly remarkable result of, unit value when K goes to infinity. Moreover, complexity and overhead of the scheme is studied and a link to (feedback free) network coding is established

Variability Among Electronic Cigarettes in the Pressure Drop, Airflow Rate, and Aerosol Production (2011)

There was significant variability between and within brands in the airflow rate required to produce aerosol, pressure drop, length of time cartridges lasted, and production of aerosol. Variation in performance properties within brands suggests a need for better quality control during e-cigarette manufacture.
Building an effective recommender system using machine learning based framework (2017)

Machine learning forms the base of many information retrieval applications those effect our day to day lives directly or indirectly. One of the Commonly used application of machine learning algorithms is Recommender Systems. Recommender system are information flitering system which takes users rating for items into account and predict user preferences. Many online ecommerce and other categorical websites are able to generate recommendations either on the basis of implicit feedback or explicit feedback. In implicit feedback, preferences are actually based on analysis of browsing patterns of the user, for example, purchase history, web logs etc. Explicit feedback is generated from the ratings provided by the user. In this paper we have shown adaption of collaborative filtering in Apache Mahout platforms via Eclipse on a sample data set.

Measurement of Traceability Error for Calibration Service Center Using Type S Thermocouples (1995)

We measured the traceability error for nine high temperature calibration service centers including KRISS through the round-robin test. In this test the type S thermocouple, which used as a calibration standard thermometer commonly, was accommodated as a test thermocouple. Intercomparison data of three institutions were coincident with KRISS's data within , which was the calibration uncertainty of the type S thermocouple, but the remaining six institution's data were deviated from the assigned uncertainty level. Deviation of the intercomparison data increased gradually according to the increase of the test temperature. and the maximum difference was so large as about at the highest test temperature, gold point. In this study we found the traceability error of high temperature calibration service center for a high temperature standard was within .
Malignant peripheral nerve sheath tumors of the head and neck: A clinicopathological study (1994)

Twenty-seven cases of malignant peripheral nerve sheath tumors involving the head and neck region over a period of 7 years were reviewed. They were graded from 1-3 based on necrosis, mitosis, cellularity, and pleomorphism. Mean age of occurrence was 42 years, with a range of 12-70 years. Male preponderance was noted (M:F = 3.5:1). The most common site of involvement was the neck (44.6%). The main presenting symptom was an enlarging mass. The nerve of origin could be identified in 33% of patients. Treatment consisted of wide excision. The 5-year observed survival was 33%. Fifty-two percent of patients developed local recurrence of disease. Fifteen percent of patients died due to advanced local disease within 18 months of treatment. Distant metastasis was seen in 18.5% of patients. Lymph node metastasis was not seen. At the end of 5 years 15% of patients remained disease free. Large tumor size (> 5 cm) adversely affected the prognosis (P = < 0.1). No significant correlation was noted between the grade of tumor and survival.
High In-Wafer Uniformity of Growth Rate and Carrier Concentration on n-Type 4H-SiC Epitaxial Films Achieved by High Speed Wafer Rotation Vertical CVD Tool (2018)

In this study, influence of both Si/H 2 ratio and C/Si ratio on growth rate uniformity and carrier concentration uniformity of n-type 4H-SiC epitaxial films grown by high speed wafer rotation vertical CVD tool was investigated. It was found that changes in radial profile of the growth rate and the carrier concentration obtained by varying Si/H 2 ratio showed quite similar behavior to those obtained by varying C/Si ratio. Such a similar trend would suggest that the distribution of local C/Si ratio near the wafer surface changes depending on total Si/H 2 ratio similarly to total C/Si ratio. Additionally, by using this relationship, both the growth rate uniformity of 49.2 μm/h ±1.78% (1.15% σ/mean) and carrier concentration uniformity of 1.08 ×10 16 cm -3 ±6.15% (3.40% σ/mean) was achieved.
P6327Prognostic value of pre-procedural 6 minute walk test in patients undergoing MitraClip implantation - insights from the German mitral valve interventions registry (2017)

The 6 minute walk test (6-MWT) has been established as an important tool for functional assessment in heart failure patients. However, its prognostic impact on outcome in a mitral regurgitation population undergoing transcatheter mitral valve repair is unknown. Purpose: The present study assessed the 1-year outcome of patients after Mitr-aClip implantation depending on the result of the pre-procedural 6-MWT. Methods: This present work represents a sub-analysis of the German, prospective, multicenter, transcatheter mitral valve interventions (TRAMI) registry. Of the main study cohort (n=828) 326 patients underwent a 6-MWT prior to their procedure. Patients were assigned to 2 groups depending on the pre-procedural 6-MWT distance using the median (<200m [group 1] vs. 200m [group 2]). Results: A total of 153 patients in group 1 and 173 patients in group 2 were available for the analysis. Among other differences in baseline characteristics patients in group 1 were older (778 years vs. 739 years; p<0.001) and had more severe multimorbidity as indicated by the STS score (128% vs. 86%; p=0.026). No differences regarding technical success defined as the absence of conversion to open heart surgery and residual mitral regurgitation 2+ (3% vs. 4%; p=0.71) and hospital MACCE (2% vs. 2%; p=0.88) were observed between the groups. With regard to 1-year outcome, patients with a distance in 6-MWT <200m had higher all-cause mortality (26% vs. 14%; p=0.013) as compared to those with a 6-MWT distance 200m. After adjustment for baseline risk factors, 6-MWT distance <200m still showed a strong trend towards increased 1-year all-cause mortality (HR 1.62, 95% confidence interval 0.95-2.74; p=0.075).
