Metadata for the HiWASE instrumentation deployed on the OWS Polarfront between September 2006 and December 2009

Between 1978 and 2009 the Norwegian weather ship Polarfront made continuous meteorological and surface wave measurements at Station M (66oN 2oE). In September 2006, as part of the UK-SOLAS HiWASE project (Brooks et al., 2009) the ship’s existing systems were complemented by the AutoFlux system (Yelland et al., 2009) to measure the transfers of momentum, heat and CO2 between the atmosphere and the ocean. Similarly, the ship's existing ship-borne wave recorder (SBWR) was supplemented by installing a commercial directional wave radar "WAVEX" made by the Norwegian firm MIROS. This report describes the metadata for the HiWASE instrumentation deployed on the OWS Polarfront between September 2006 and December 2009. Sensor serial numbers, dates of sensor changes and problems with sensors are contained in the associated tables.
A novel low-carbon space conditioning system incorporating phase-change materials and earth–air heat exchangers

The energy expended for conditioning buildings around the world is worryingly large and increasing every year. Currently, almost half of houses around the world use some type of energy-expensive conventional air-conditioning system. These systems are high emitters of gases such as carbon dioxide and so high contributors to climate change. Consequently, alternatives must be considered. Earth–air heat exchangers (EAHEs) and phase-change materials (PCMs) may be options; they have, however, limitations. This paper proposes a novel hybrid space-conditioning system combining EAHEs with PCMs, which uses surfaces as sources of heating or cooling to provide better temperature distribution across a space and comfort enhancement with low energy use. The idea is to use an EAHE to provide cool air to discharge the PCM, consequently helping to overcome most of the limitations of both strategies. Two of a series of experiments undertaken to test the proposed system are reported in this article. The EAHE + PCM system compared with a reference room could decrease temperature swings by up to 47%. The system was proved to work although further work is required to make it commercially viable.
On The Design of SLA-Aware and Cost-Efficient Event Driven Microservices

Event streaming and event driven microservices are gaining more attention for architecting scalable cloud software and data systems. Event driven microservices communicate asynchronously over distributed event bus (also called distributed event broker). In event driven microservice architectures a producer microservice creates an event and pushes it into a distributed event broker. On the other side, a consumer microservice pulls the event out of the broker and performs the required business logic on the event. In this work, we propose a methodology and framework for tail latency (high percentile latency) SLA guarantee of event driven consumer microservices. We show a cost-efficient proactive and reactive horizontal autoscale mechanism of consumer microservices to optimize for tail latency of event processing time. In the proposed framework, each latency-sensitive consumer microservice is configured with a maximum latency for event processing, and the framework guarantees autonomous scale in and out of consumer microservice instances to target the required latency SLA under minimal number of replicas. Moreover, we show and discuss the effect of consumer microservices provisioning and synchronization time on the overall latency SLA guarantee.
Evaluation of electric mobility authentication approaches

For the public charging of Electric Vehicles (EVs), ISO 15118 specifies the Plug and Charge (PnC) approach. Unfortunately, PnC requires a quite complex Public Key Infrastructure (PKI) and completely lacks privacy-preserving measures. This work shows that other approaches from the literature and a novel introduced approach outperform PnC. All thirteen approaches were rated based on a developed evaluation methodology, regarding their security, usability, offered features and interoperability. For the best approaches recommendations regarding a more detailed analysis and comparison are given. These promising approaches should be further analyzed and more detailed specified, in order to mitigate current security flaws and offer the user a great and easy charging experience.
Risk Evaluation and Analysis on Simulation Model of Fire Evacuation based on CFD - Focusing on Incheon Bus Terminal Station

Recently, the research to visualize and to reproduce evacuation situations such as terrorism, the disaster and fire indoor space has been come into the spotlight and designing a model for interior space and reliable analysis through safety evaluation of the life is required. Therefore, this paper aims to develop simulation model which is able to suggest evacuation route guidance and safety analysis by considering the major risk factor of fire in actual building. First of all, we designed 3D-based fire and evacuation model at a subway station building in Incheon and performed fire risk analysis through thermal parameters on the basis of interior materials supplied by Incheon Transit Corporation. In order to evaluate safety of a life, ASET (Available Safe Egress Time), which is the time for occupants to endure without damage, and RSET (Required Safe Egress Time) are calculated through evacuation simulation by Fire Dynamics Simulator. Finally, we can come to the conclusion that a more realistic safety assessment is carried out through indoor space model based on 3-dimension building information and simulation analysis applied by safety guideline for measurement of fire and evacuation risk.
AC 2011-303: BRIDGING THE VALLEY OF DEATH: A 360 APPROACH TO UNDERSTANDING ADOPTION OF INNOVATIONS IN ENGINEER- ING EDUCATION

There is a nationwide need to better translate engineering education research into the classroom setting. Moving engineering education research into practice is a more complicated task than it might initially seem. There are many significant barriers to hinder the transition from research to implementation. These barriers can be categorized into two groups: (1) individual barriers, such as personality characteristics that contribute to a lack of willingness to implement innovations, as well as a lack of knowledge about engineering education research; and (2) environmental perceptions, such as perceptions of the tenure and promotion that suggest a lack of support for innovations. The project discussed in this paper investigates the characteristics of faculty members who successfully adopt engineering education innovations and studies the impact of their working environment on their decision to adopt. Additionally, the project investigates characteristics of faculty members who do not adopt engineering education innovations and whether that decision was affected by perceptions of their working environment. This paper describes the identification of current barriers to the adoption of innovations in engineering education using a 360° approach. Perspectives include that of self, colleagues, students, experts in education innovation (such as the director of a center for teaching and learning), and the reality (from administrators and published documents) and perceptions (from individuals) of the tenure process and rewards/incentives. This 360° approach provides a foundation for bridging the gap, often referred to as the ‘valley of death,’ between engineering education research and the common practice of engineering education.
of Surface Roughness on Airframe Noise

The generation of sound by turbulent boundary layer flow at low Mach number over a rough wall is investigated by applying the theoretical model which describes the scattering of the turbulence near field into sound by roughness elements. Attention is focused on a numerical method to approximately quantify the absolute level of the roughness noise radiated to far field. Empirical models for the source statistics are obtained by scaling smooth-wall data by the increased skin friction velocity and boundary layer thickness for a rough surface. Numerical integration is performed to determine the roughness noise, and it reproduces the spectral characteristics of the available empirical formula and experimental data. Experiments are conducted to measure the radiated sound from two rough plates in an open jet by four 1/2” free-field condenser microphones. The measured noise spectra of the rough plates are above that of a smooth plate in 1‐2.5 kHz frequency and exhibits encouraging agreement with the predicted spectra. Also, a phased microphone array is utilized to localize the sound source, and it confirms that the rough plates have higher acoustic source strengthes in this frequency range. A parametric study illustrates that the roughness height and roughness density significantly aect the far-field radiated roughness noise with the roughness height having the dominant eect. The estimates of the roughness noise for a Boeing 757 sized aircraft wing with idealized levels of surface roughness show that in high frequency region the sound radiated from surface roughness may exceed that from the trailing edge, and higher overall sound pressure levels for the roughness noise are also observed.
A miniature capacitance dilatometer for magnetostriction and thermal expansion measurements

In the present article we want to report about our miniature capacitance dilatometer developed for magnetostriction and thermal expansion measurements. The dilatometer is foreseen to be used on millimeter-sized single crystalline samples in the temperature range 2 – 320K. The dilatometer main body is produced of brass and is mounted in low vacuum. The capacitance was measured with a digital, self-balancing, three terminal, commercial capacitance bridge operating in the frequency range 50 Hz − 20 kHz. The temperature was determined using commercial resistive thermometers Cernox BG 1030 and Cryo-con Model 44 Temperature controller.
Improved equivalent circuits for complementary split-ring resonator-based high-pass filter with C-shaped couplings

The authors modify the complementary split-ring resonator (CSRR) with dual C-shaped couplings for high-pass filter (HPF) design and propose improved equivalent circuits as a means to analyse the filter. The π-type circuit of the dual C-shaped coupling in the CSRR-based HPF is presented to have the improved equivalent circuit in contrast to the conventional equivalent circuit. At 3 dB, the cut-off frequency fc=1.74 GHz, the maximum IL is within 0.33 dB up to 8 GHz and the 65.81 dB rejection extends down to 0.53 GHz. Simulation and measurement results including surface current distributions and frequency responses are presented and discussed.
Building trust in virtual organisations: a case study of trust and gender in a scientific virtual organisation breeding environment

This paper examines an online life science virtual organisation breeding environment (VBE), an incubator of temporary or more permanent virtual organisations (VOs). In the VBE studied, scientists could connect and collaborate with one another using various social media technologies such as profiles, messaging, blogs, and forums. This article is particularly focused on the ways in which social media technologies facilitate interactions between participants in the 'WomenScientists1' group. This study employs content analysis of all textual discourse on the group and social network analysis to understand the relationship of users in this network. This paper seeks to address three core questions. First, we explore what types of interactions facilitate trust formations. We find that interactions that share personal information positively elicit trust from other users. Second, we examine which demographic attributes contribute to the growth of trust interactions. We find that a user's gender and their membership of the group are correlated with trust interactions. Third, we find that if users are unilaterally trusted (via a 'leap of faith'), they are likely to reciprocate, forming bilateral or multilateral trust relationships.
A novel position sensorless control scheme for doubly fed reluctance motor drives

A novel position sensorless control algorithm for the newly developed doubly fed reluctance motor (DFRM) drives is presented. The control makes use of the 60 Hz terminal variables, which are easy to acquire and process, for estimation and control of the torque angle of the machine, while the speed of the system is given in an open-loop mode. The control is robust and suitable for variable-speed pump-type application. With this control, the required VA ratings of the PWM converter are only 50% of that of the DFRM motor, and the motor can be started with full load torque. This control scheme has been successfully implemented on a 2-HP DFRM drive. >
How do firms perform effective competency development

A growing body of evidence suggests that distinctive technological competence provide the basis for superior firm performance. However, few if any firms possess all the prerequisite competencies required for a given technology-product-market paradigm as they enter that market. Consequently, firms employ different ways to acquire and develop competencies in response to the changing requirements of industry standard products. This study of 112 different firms in the semiconductor silicon industry suggests that the characteristics of a technology effect the learning method chosen by a firm. The role that ten learning methods have in the acquisition and development stage of a competence is also considered.
RECOMMISSIONING OF THE CERN INJECTOR COMPLEX BEAM INSTRUMENTATION

During the last two years, the CERN injector complex has been completely renovated with the aim of providing high intensity and smaller emittance beams to the LHC. A new Linac providing Hhas been constructed and major upgrades in the Proton Synchrotrons (PS Booster ring, PS ring and Super PS ring) have been performed. A full suite of new beam diagnostics has been implemented and commissioned. This includes fast wire scanners, beam gas ionization monitors, quadrupolar pick-ups and diamond beam loss detectors. New radiation-hard beam position monitoring system was also successfully deployed in the SPS. This talk will present an overview of the performance of the newly built instruments.
On the Development of an Oil-Free, High-Speed and High-Temperature Turboalternator

In the paper the authors will present the design and preliminary test results for a distributed electric generating system that uses renewable energy sources for economical load-following and peak-shaving capability in an oil-free, high-speed micro-turboalternator system using compliant foil bearings and a permanent magnet alternator. The high operating temperatures and speeds required to make the Renewable Energy Turbo-Alternator (RETA) an efficient and cost effect system require that oil-free compliant foil bearings be used and that the alternator section be isolated from the turbine. Preliminary simulator testing compares well with design predictions and shows a stable rotordynamic and thermal environment.Copyright © 2010 by ASME
Table Understanding in Practice Madelon

We understand images, videos, and natural language, but tables are still a mystery. As a result, technological advances stay behind to intelligibly navigate, manage and exploit tables, while they pile up in databases. Lyft’s data discovery system, Amundsen [3], and Google’s Dataset Search [1], for example, still rely on manually provided table metadata. The practical success of deep learning stimulates the development of table understanding models to close this gap. With models like Sherlock [6] and TURL [2], we can obtain table embeddings that encode their schema, relations, and entities. Evaluations of these models show impressive accuracy for generating metadata to facilitate tasks like data search and integration. These experiments, however, illustrate performance within an isolated context. We observed that actual deployment of table understanding models beyond this context is still challenging for various reasons.
VICCI: A Programmable Cloud-Computing Research Testbed

VICCI is a programmable cloud-computing research testbed t hat provides an experimental platform for developing next-generation Internet services. VICCI encomp asses a distributed set of virtualized compute clusters and networking hardware, as well as thesoftwarethat enables multiple researchers to innovate both at and above the infrastructure layer. VICCI is designed to s upport research into the design, provisioning, and management of a global, multi-datacenter infrastructu e—thecloud—and also into the design and deployment of large-scale distributed services that use such an environment. VICCI is a distributed instrument, with a point-of-presence at Princeton, Georgia Tech, Stanf ord, and the University of Washington, along with international clusters in Europe and Japan. VICCI enables a broad research agenda in the design of networ k systems that require both multiple points-of-presence and significant compute/storage capab ility at each site. It enables research in: Building block services designed to be used by other cloud applications. As cloud computing becomes increasingly prevalent, the demands for new services will increase. VICCI supports the development of much-needed services that address issues of replication , consistency, fault-tolerance, scalable performance, object location and migration. Researchers can expl or multiple—sometimes conflicting, sometimes complementary—approaches to these problems. New cloud programming models designed for targeted application domains. These models— focused, for example, on constructing virtual worlds and ma naging personal data—are designed to give application writers a way to think about programming the clo ud. Cross-cutting issues at the foundation of the cloud’s design. The VICCI testbed allows research teams to investigate fundamental issues related to cloud co mputing, including how the network is managed within data centers, between data centers, and between a mul ti-site cloud and end-users, and how to build a trusted cloud platform that ensures the confidentiality and integrity of hosted computations. VICCI has been bootstrapped with working software from Plan etLab, a next-generation Internet testbed developed at Princeton that is used by thousands of research ers and has carried live traffic for millions of users worldwide. Our ultimate goal is to fold the results of V ICCI research back into the testbed itself, allowing us to improve the system over time and making it an ev en more effective platform for research into scalable network systems. VICCI is designed to provide a realistic environment to eval uate and deploy scalable network services. Our philosophy for VICCI is strongly influenced by our experi ence with PlanetLab, which has demonstrated the importance of deploying experimental network services on platforms that are realistic enough to attract a real-user community. It is only by observing how experiment al systems are used in practice that researchers
Performance Investigation of Multi-Phase VSI with Simple PWM Switching Techniques

This paper presents the performance of multi-phase voltage source inverter (VSI) with simple PWM switching techniques, namely the harmonic injection and offset injection method. The technique discussed in this paper is easy to implement and avoid complicated controlling algorithm adapted in SVPWM technique. The generalized switching techniques are proposed in this paper. A generalized algorithm suitable for odd number of phases is developed in Matlab/Simuli nk environment and discussed in detail for both the switching methods. The performance of the 5, 7 and 9-phase VSI is studied with the above-said switching methods. The results of the simulation are presented for different modulation indices and a comparison in terms of fundamental voltage and THD identifies the better scheme suitable for multi-phase inverter fed drives.
New digital control of forced commutation HVDC converter supplying into load system without AC source

The authors describe a digital control technique for a forced commutation converter applied to HVDC transmission systems with loads which have no AC sources. The technique used direct calculation of the firing angle of the inverters. The results of simulator experiments and computer simulations show good performance for the regulation of the AC voltage of a load system without an AC source. In particular, it works well when a ZnO arrester is installed to suppress overvoltage which occurs when the load in the receiving system is suddenly rejected. The results show that the control technique drastically shortens the overvoltage duration and decreases the amount of energy absorbed by a ZnO gapless arrester installed at the inverter station. >
A Novel and Robust Approach to Detect Tuberculosis Using Transfer Learning

Deep learning has emerged as a promising technique for a variety of elements of infectious disease monitoring and detection, including tuberculosis. We built a deep convolutional neural network (CNN) model to assess the generalizability of the deep learning model using a publicly accessible tuberculosis dataset. This study was able to reliably detect tuberculosis (TB) from chest X-ray images by utilizing image preprocessing, data augmentation, and deep learning classification techniques. Four distinct deep CNNs (Xception, InceptionV3, InceptionResNetV2, and MobileNetV2) were trained, validated, and evaluated for the classification of tuberculosis and nontuberculosis cases using transfer learning from their pretrained starting weights. With an F1-score of 99 percent, InceptionResNetV2 had the highest accuracy. This research is more accurate than earlier published work. Additionally, it outperforms all other models in terms of reliability. The suggested approach, with its state-of-the-art performance, may be helpful for computer-assisted rapid TB detection.
