Implementing an SMB2 Server in the Vortex Operating System

With the advent of computer networks, the ability for sharing and accessing files across the network between multiple workstations and remote servers was sought after. In the nineteen eighties, prominent networked file systems were developed and reached widespread adoption among enterprise businesses and institutions. A few of these, notably Networked File System (nfs) and Server Message Block (smb), survived the transition into the Internet era and the successors of these protocols remain the default network file systems on contemporary operating systems today. Clouds are comprised of thousands of computers, hosted in centralized data center facilities. These computers run modified versions of contemporary operating systems, with a monolithic, micro or hybrid kernel. Contemporary operating systems lack fine-grained control over resource allocation. The Omni-kernel architecture is a novel operating system architecture designed for pervasive monitoring and scheduling of system resources. Vortex is an experimental implementation of the Omni-kernel architecture. The Vortex operating system lack utilities to expose its native file system over the network. This thesis describes the introduction of a minimal Server Message Block version 2 (smb2) server to the Vortex operating system. We achieve interoperability with contemporary client(s) and document acceptable throughput performance.

The Business Diagnostics Model Addressing its Components Variation Dynamics

Introduction The purpose of the reasoning described in this paper is not to solve any methodological issues of economic diagnosing, but to present the application of selected information technology methods in this field, addressing the internal dynamics of a system that any company constitutes. The economy-related issues have been referred to as far as required in order to: – substantiate the purposefulness of taking up the subject of the study, – formulate the economic problems to be solved, in a manner addressing the specific nature of the data exploration methods that have been selected. The intention behind the approach presented in this paper is to improve the effectiveness of diagnostic methods being in use today, as they not always provide a complete picture of the situation well enough in advance, but identify some areas of risk only, based on indicators computed in a standard manner. To understand these correctly, a substantial experience and expert knowledge is needed. This view is supported by most of the authors specializing in economics and business management. According to Jae K. Shim i Joel G. Siegel [Shim 2001, p. 555]: “Although financial ratio analysis is useful in predicting failure, it is limited because methodology is basically univariate. Each ratio is examined in isolation, and it is up to the CFO to use professional judgement to determine whether a set of financial ratios are developing into a meaningful analysis. ” Another critical opinion on using financial control as the sole indicator of growth in the age of information revolution is given by Kaplan and Norton [Kaplan, 2006] in their work presenting the balanced scorecard concept. Thus, we are facing a situation where a demand for more effective and broader approach has developed and on
Novelty detection for SHM using raw acceleration measurements

Structural health monitoring is a problem that can be addressed at many levels. One of the most promising approaches used in damage assessment problems is based on pattern recognition. The idea is to extract features from data that characterize only the normal condition and to use them as a template or reference. During structural monitoring, data are measured, and appropriate features are extracted as well as compared with the reference. Any significant deviations are considered as signal novelty or possible damage. Several studies present in the literature are based on the comparison of measured vibration data such as natural frequencies and vibration modes in undamaged and damaged states of the structure. This methodology has proven to be efficient; however, its application may not be the most adequate in cases where the engineer needs to know with certain imperativeness the condition of a given structure. This paper proposes a novelty detection approach where the concept of symbolic data analysis is used to manipulate raw vibration data (i.e., acceleration measurements). These quantities (transformed into symbolic data) are combined to three unsupervised classification techniques: hierarchy agglomerative, dynamic clouds and soft c‐means clustering. In order to attest the robustness of this approach, experimental tests are performed on a simply supported beam considering different damage scenarios. Moreover, this paper presents a study with tests conducted on a motorway bridge, in France, where thermal variation effects also play a major role. In summary, results obtained confirm the efficiency of the proposed methodology. Copyright © 2015 John Wiley & Sons, Ltd.
ADCY2, ADCY5, and GRIA1 are the key genes of cAMP signaling pathway to participate in osteoporotic peripheral and spinal fracture after the manipulation of Wnt signaling

Background Osteoporotic peripheral and spinal fracture, characterized by high morbidity and mortality, has become a health burden for the aging population. The inactivation of the Wnt signaling has been proved to promote osteoporotic fractures. Our study is to identify the key genes, miRNAs, and pathways that possibly lead to osteoporosis and osteoporotic peripheral and spinal fracture after the aberrant activation or mutation of Wnt signaling pathway. Methods Impute R package was used to screen out the differently expressed genes (DEGs) and differently expressed miRNAs in GEO datasets. STRING and Metascape were used to construct protein-protein interactions (PPI) network, gene ontology (GO) enrichment and pathway enrichment. Results 562 DEGs were screened out using Impute R package, and a PPI network involving the 562 DEGs was constructed using STRING and Metascape. GO enrichment and pathway enrichment showed that the 562 DEGs were associated with membrane protein-related signaling pathways. Then, 75 genes between the target genes of miR-18a-3p and 562 DEGs were overlapped using Venny 2.1. 0. Finally, the cAMP signaling pathway was identified as the key pathway, whilst ADCY2, ADCY5, and GRIA1 were identified the key genes that possibly participate in osteoporotic peripheral and spinal fracture after the manipulation of Wnt signaling pathway. Conclusions The results demonstrated that ADCY2, ADCY5, and GRIA1 were the key genes to regulate the cAMP signaling pathway in osteoporotic peripheral and spinal fracture after abnormal Wnt signaling.
The Future of Small Navy Ship Sickbays and Army Aeromedical Evacuation Aircraft

Abstract : The Office of the Chief of Naval Operations commissioned a study to investigate the future configuration of Navy ship sickbays. Due to space constraints, sickbay capabilities are limited. Similarly, Army aeromedical evacuation helicopters have limited space to treat patients. This joint study explores how to best utilize advanced medical technologies in the sickbay of the future for the Navy s cruiser, littoral combat ship, and mine countermeasure ship and Army aeromedical evacuation platforms. This study assesses the current portable medical technologies in the selected Navy ship authorized medical allowance lists to support the force health protection functions. The study also evaluates portable medical devices in Army aeromedical evacuation medical equipment sets. Collectively, capability gaps are identified and serve as the baseline for recommending future medical technologies. This study recommends medical devices with the potential to advance patient care and proposes significant investments in bandwidth, network, and infrastructure. Smart technologies will be important in space-constrained medical environments; however, organizational restructuring and policy change is required to address the root cause of outdated medical systems. This study also recommends more inter-service collaboration, the establishment of an aeromedical evacuation program of record, and the utilization of open systems architecture for procuring future medical devices.
An abuttable CCD imager for visible and X-ray focal plane arrays

Large multichip arrays for close-abutted CCDs (charged-coupled devices) are needed for surveillance applications in the visible band and for X-ray astronomy missions such as the Advanced X-ray Astrophysics Facility and the ASTRO-D satellite. A 420*420 pixel frame-transfer CCD imager which is designed to be abutted to other imagers on three sides so that arrays of 2*N chips can be constructed has been developed. A three-phase, triple-poly, buried-channel process is used, and the die size is 12 mm*20 mm. The arrays provide low-noise readout circuitry and high charge-transfer efficiency at low charge levels, critical requirements for both of the above applications. The device has also been shown to be suitable as a soft X-ray imager operating in a spectroscopic mode. <<ETX>>
Prevalence of non-alcoholic fatty liver disease on computed tomography in patients with inflammatory bowel disease visiting an emergency department

Background Non-alcoholic fatty liver disease (NAFLD) is common in patients with inflammatory bowel disease (IBD). The purpose of this study was to further examine the prevalence of NAFLD in IBD patients. Methods We retrospectively reviewed the medical records of IBD patients who visited the emergency department because of abdominal pain between January 2009 and December 2014. These were compared with a group of 70 controls without IBD, matched for age and body mass index (BMI). Computed tomography data were analyzed for the presence or absence of hepatic steatosis. Patient with recent steroid or excessive alcohol use were excluded. Univariate and multivariate analyses were performed. Results NAFLD prevalence was 44% (31/70) in the IBD group vs. 16% (11/70) in controls (P<0.001). There was no significant difference between the 2 groups in age, sex distribution, BMI, presence of diabetes, or levels of serum transaminases, serum albumin or platelets. In multivariate analysis, the presence of IBD was independently associated with NAFLD (odds ratio 4.53, 95% confidence interval 2.00-10.26; P=0.002). Conclusions The presence of IBD is strongly and independently associated with NAFLD. Systemic inflammation and alteration of the intestinal microbiome have been proposed as mechanisms, but further studies are needed to better elucidate the pathophysiology.
Resource Allocation for Heterogeneous Service in Green Mobile Edge Networks Using Deep Reinforcement Learning

The requirements for powerful computing capability, high capacity, low latency and low energy consumption of emerging services, pose severe challenges to the fifth-generation (5G) network. As a promising paradigm, mobile edge networks can provide services in proximity to users by deploying computing components and cache at the edge, which can effectively decrease service delay. However, the coexistence of heterogeneous services and the sharing of limited resources lead to the competition between various services for multiple resources. This paper considers two typical heterogeneous services: computing services and content delivery services, in order to properly configure resources, it is crucial to develop an effective offloading and caching strategies. Considering the high energy consumption of 5G base stations, this paper considers the hybrid energy supply model of traditional power grid and green energy. Therefore, it is necessary to
Input current shaper using Cuk converter

The Cuk converter with integrated magnetics when used for input current shaping exhibits advantages over other topologies. When the 'ripple steering' mechanism is employed, essentially zero input and output current ripples are obtained for all operating conditions, and the size of the magnetics can be significantly reduced. The discontinuous inductor current mode (DICM) with no current feedback loop is analyzed. Current shaping takes place automatically by keeping the duty cycle and switching frequency constant when the converter operates in DICM. The high input power factor and high overall conversion efficiency suggest operation in DICM for low-power applications. Experimental results obtained on a 200-W prototype are presented. <<ETX>>
Systems engineering effective supply chain innovations

When seeking to adopt innovative supply chain (SC) best practices from apparently better-performing organisations during re-engineering, it is important to acknowledge that context also impacts performance. Hence, the purpose of this study is to evaluate the SC uncertainty circle model for its potential to yield direct performance comparisons even when the benchmarked organisations are located in different business sectors and economic settings. Using a rigorous well-established audit methodology, longitudinal field research with an engineer-to-order SC company demonstrates how highly effective, potentially transferable best practices can be reliably identified when systems thinking is allied to a context-free uncertainty metric, and how reducing product delivery process uncertainty can itself increase innovation capability.
ROAD SAFETY AUDIT, THE DANISH EXPERIENCE

As in other countries, accident reduction has been established practice within the Danish road authorities for many years. Road safety experts, studying accident black spots and designing low-cost safety improving measures, have obtained an extensive experience in what is safe and unsafe in road layout. Safety Audit is a formal procedure to bring this knowledge into the road planning and design process. The procedure originally in the U.K. The introduction of a formal system of discussing road safety matters on the design stage may in certain cases gives rise to strong reactions from the planning and design organizations. However, the management of the Directorate strongly supports the idea and expresses the view that safety audit has come to stay. Results of the evaluation study appeared June 1995.
Phase Shift Torquemeters for Gas Turbine Development and Monitoring

Multipole phase shift torquemeters now measure shaft power to 0.1% accuracy in R & D applications, and to 1.0% when designed for permanent installation, both at confidence levels of 95%.

They are in service at speeds up to 90,000 RPM and powers of 50MW.The paper outlines ways of ensuring credibility, and describes typical designs for R & D use, and for permanent installation. It concludes that the application problems are largely those of transmission engineering.Copyright © 1991 by ASME
USING THE ABSORBED POWER METHOD TO EVALUATE EFFECTIVENES OF SELECTED SEAT CUSHIONS DURING MANUAL WHEELCHAIR PROPULSION

Although wheelchair users are constantly subjected to oscillatory and shock vibrations not much research has been conducted to assess the whole-body vibrations experienced by wheelchair users. Studies that have been published have only involved the testing of manual wheelchairs not interventions such as suspension or seating systems.The purpose of this study was to determine if selected wheelchair cushions reduce the amount of harmful whole-body vibrations transferred to wheelchair users and, if the absorbed power method a good measure of evaluating the whole-body vibrations.Thirty-two participants, who use a wheelchair as their primary mode of mobility, partook in this study. Four of the most commonly prescribed wheelchair cushions were selected. Participants were asked to propel their wheelchair over a simulated activities of daily living (ADL) obstacle course while acceleration and force data was collected.A repeated measures ANOVA showed no significant differences between the different cushions for the total averaged absorbed power (p = .190), the 50 mm curb drop (p = .234), or the rumble strip (p = .143). A repeated measures ANOVA for the peak curb drop absorbed power revealed a significant difference in the cushions (p = .043). The cushions that appeared to perform the best in this testing appear to be the Invacare Pindot and the Varilite Solo. Not only did those cushions appear to have the lowest values much of the time but did not display the highest values. Absorbed power appears to be just as effective at determining the effects of vibrations in the time domain as the prescribed methods of the ISO 2631 standard.
Fully Distributed Tunable Bandpass Filter Based on Thin-Film Slow-Wave Structure

This paper presents simulation and measurement results of fully distributed tunable coplanar bandpass filters (BPFs) with center frequencies around 6 GHz that make use of ferroelectric Barium Strontium Titanate (BaxSr1−xTiO3 or BST-x) thin film as tunable material. The two experimental bandpass filters tested are based on a novel frequency-agile structure composed of cascaded half wavelength slow-wave resonators (2 poles) and three coupled interdigital capacitors (IDCs) optimized for bias voltage application. Devices with gap dimensions of 10 and 3 μm are designed and fabricated with a two-step process on polycrystalline Ba0.5Sr0. 5TiO3 thin films deposited on alumina substrate. A frequency tunability of 9% is obtained for the 10 μm gap structure at ±30 V with 7 dB insertion loss (the BST dielectric tunability being 26% with 0.04 loss tangent for this gap size). When the structure gap is reduced to 3 μm the center frequency shifts with a constant 9 dB insertion loss from 6.95 GHz at 0 V to 9.05 GHz at ±30 V, thus yielding a filter tunability of 30% (the BST dielectric tunability being 60% with 0.04 loss tangent for this gap size), a performance comparable to some extent to localized or lumped element BPFs operating at microwave frequency (>2 GHz).

Aerodynamic Drag and Drag Reduction: Energy and Energy Savings (Invited)

An assessment of the role of fluid dynamic resistance and/or aerodynamic drag and the relationship to energy use in the United States is presented. Existing data indicates that up to 25% of the total energy consumed in the United States is used to overcome aerodynamic drag, 27% of the total energy used in the United States is consumed by transportation systems, and 60% of the transportation energy or 16% of the total energy consumed in the United States is used to overcome aerodynamic drag in transportation systems. Drag reduction goals of 50% are proposed and discussed which if realized would produce a 7.85% total energy savings. This energy savings correlates to a yearly cost savings in the $30Billion dollar range.
An Electropalatographic Study of English 1, r, Flap and the Korean Liquid ㄹ

Korean learners of English are quite confused with similarities and dissimilarities between English liquids, 1 and r, and the Korean single liquid ㄹ. This study attemps to clarify the relationship between these by the electropalatographic (EPG) and spectrographic method. Material from one Korean and one American English speaker was collected. The results of the EPG study showed that the Korean word-final and geminate 2 is similar to English clear-1. Also it was found that there is no tongue tip contacts on the alveolar ridge for English dark-1 as shown in the pictures in the phonetics books. The intervocalic Korean liquid was a flap which was similar to English t, d flapping, despite certain differences in constriction location and breadth of contact. The Korean initial liquid sound in borrowed words was also realized as a flap. Results thus supported the description of Korean liquid allophones by Tsuzuki in 1992.
