Generating project value through design for reliability : on the development and implementation of a potential value framework (2007)

The current trend to economically exploit deepwater hydrocarbon reserves is to reduce\nthe capital expenditure; accomplished by deploying subsea equipment. The financial\nbenefit afforded is offset by the risk of high operational costs associated with failure.\nRecognition of the life cycle cost implications of subsea reliability have led to the\ndevelopment of the reliability strategy. This strategy adopts a risk based approach to\ndesign for reliability where only analyses (and their subsequent recommended actions)\nperceived to add to whole project value are implemented. While life cycle costing has\nbeen developed to address through life cost, analyses are traditionally considered a\nsource of cost accumulation rather than value creation.\nThis thesis proposes a potential reliability value decision making framework to assist in\nthe design for reliability planning process. The framework draws on the existing\nconcepts of life cycle costing to explicitly consider the through life value of investing in\nreliability analyses. Fundamental to the framework are the potential reliability value\nindex and an associated value breakdown structure intended as central decision support\nfor decentralised decision making.\nImplementation of the framework is reliant on synergies within the project organization;\nincluding relationships between organizations and project functions. To enhance\nsynergy between functions and dismantle some of the recognised barriers to\nimplementing the reliability strategy an organizational structure, for projects, guided\ncentrally by the reliability value framework is proposed. This structure requires the\nbroadening of each project functions’ skill set to enable the value added implementation\nof the strategy’s activities. By widening the scope of application, the reliability analysis\ntoolkit becomes the central guidance of the design process and awareness of the causes\nof unreliability and how they can be avoided increases. As this capability improves so\nthe cost-efficiency with which reliability is managed in design (introduced as the\nreliability efficiency frontier) also increases.
In Situ Armoring: A Robust, High-Wettability, and Fire-Resistant Hybrid Separator for Advanced and Safe Batteries (2018)

Development of nonflammable separators with excellent properties is in urgent need by next-generation advanced and safe energy storage devices. However, it has been extremely challenging to simultaneously achieve fire resistance, high mechanical strength, good thermomechanical stability, and low ion-transport resistance for polymeric separators. Herein, to address all these needs, we report an in situ formed silica@silica-imbedded polyimide (in situ SiO<sub>2</sub>@(PI/SiO<sub>2</sub>)) nanofabric as a new high-performance inorganic-organic hybrid separator. Different from conventional ceramics-modified separators, this in situ SiO<sub>2</sub>@(PI/SiO<sub>2</sub>) hybrid separator is realized for the first time via an inverse in situ hydrolysis process. Benefiting from the in situ formed silica nanoshell, the in situ SiO<sub>2</sub>@(PI/SiO<sub>2</sub>) hybrid separator shows the highest tensile strength of 42 MPa among all reported nanofiber-based separators, excellent wettability to the electrolyte, good thermomechanical stability at 300 °C, and fire resistance. The LiFePO<sub>4</sub> half-cell assembled with this hybrid separator showed a high capacity of 139 mAh·g<sup>-1</sup>@5C, which is much higher than that of the battery with the pristine PI separator (126.2 mAh·g<sup>-1</sup>@5C) and Celgard-2400 separator (95.1 mAh·g<sup>-1</sup>@5C). More importantly, the battery showed excellent cycling stability with no capacity decay over 100 cycles at the high temperature of 120 °C. This study provides a novel method for the fabrication of high-performance and nonflammable polymeric-inorganic hybrid battery separators.
Shear Stability of an Elastomeric Disk Spacer Within an Intervertebral Joint: A Parametric Study (1992)

A parametric study was conducted to compare the resistance to shear force provided by three surgical implantation techniques and three endplate designs for use with a polymeric lumbar intervertebral disk spacer. While under an axial load, the implant was pushed out laterally through the surgical window created for implantation. Force at 0.3 mm displacement, slope of the initial portion of the force-displacement graph, and maximum force were measured. The results indicate that implants with pegs, inclined planes, or domes on the surfaces of the disk will add significantly to the shear stability of the implant while maintaining the simplicity of a single part device.
Curvature based shape estimation using tactile sensing (2002)

Proposes an approach-"Blind Man's" approach-to shape description in which tactile information is sensed from the fingertips of a dexterous hand. Using this contact information, we investigate two complementary methods for curvature estimation. The first method is based on rolling one finger to estimate curvature at a point on the surface. We use Montana's equations for estimating curvature at a point using simulations and analyze the sensitivity of the approach to noise. The second method uses multiple fingers to slide along a surface while sensing contact points and surface normals. We present a method to extract the shape properties of a patch obtained by fitting a B-spline surface to this multi-fingered sweep across the surface of the object. The method enables us to extract higher level shape information based on the curvature properties of patch.
A Scalable Data Integrity Mechanism Based on Provable Data Possession and JARs (2016)

Cloud storage as a service provides high scalability and availability as per need of user, without large investment on infrastructure. However, data security risks, such as confidentiality, privacy, and integrity of the outsourced data are associated with the cloud-computing model. Over the year's techniques such as, remote data checking (RDC), data integrity protection (DIP), provable data possession (PDP), proof of storage (POS), and proof of retrievability (POR) have been devised to frequently and securely check the integrity of outsourced data. In this paper, we improve the efficiency of PDP scheme, in terms of computation, storage, and communication cost for large data archives. By utilizing the capabilities of JAR and ZIP technology, the cost of searching the metadata in proof generation process is reduced from O(n) to O(1). Moreover, due to direct access to metadata, disk I/O cost is reduced and resulting in 50 to 60 time faster proof generation for large datasets. Furthermore, our proposed scheme achieved 50% reduction in storage size of data and respective metadata that result in providing storage and communication efficiency.
Reconstruction of the Upper Cervical Spine Using a Personalized 3D-Printed Vertebral Body in an Adolescent With Ewing Sarcoma (2015)

This is a case example on the concept of personalized precision medicine in a surgical setting and demonstrates how 3D-printed, patient-specific implants may bring individualized solutions to rare problems wherein restoration of the specific anatomy of each patient is a key prognostic factor.
Control systems for mobile Satcom antennas (2008)

Mobile VSAT satcom antenna systems are available on the market today but are just in their infancy. All observers of the satellite industry see great growth potential for this market. Press releases announcing a new product offering are now common, and an Internet search for "satcom on-the-move" produces tens of thousands of hits. Already one can find examples of delayed or failed products that suffered from poor control system performance. As discussed herein, a basic understanding of apertures and their performance is needed by the control system designer, to the same extent an appreciation of servo issues is needed by the antenna company product manager in possession of a suitable aperture. Clearly, a system engineering approach with careful tradeoffs of size, weight, power, radio-frequency, and control system issues should be undertaken before press releases are issued.
Hair Segmentation Using Heuristically-Trained Neural Networks (2016)

We present a method for binary classification using neural networks (NNs) that performs training and classification on the same data using the help of a pretraining heuristic classifier. The heuristic classifier is initially used to segment data into three clusters of high-confidence positives, high-confidence negatives, and low-confidence sets. The high-confidence sets are used to train an NN, which is then used to classify the low-confidence set. Applying this method to the binary classification of hair versus nonhair patches, we obtain a 2.2% performance increase using the heuristically trained NN over the current state-of-the-art hair segmentation method.
Photonic-Based RF Transceiver for UWB Multi-Carrier Wireless Systems (2014)

In this paper an all-optical system exploitable as the core structure for a photonic-based RF transceiver is presented. The proposed scheme is able to simultaneously perform either up- or down-conversion of multiple frequency Ultra-Wide Band (UWB) RF signals, employing a single Mode-Locking Laser (MLL). The system has been experimentally demonstrated and tested by up- and down-converting orthogonal frequency division multiplexing (OFDM) signals over a bandwidth of about 4 GHz. The scheme’s performance has been validated by measuring the error vector magnitude (EVM) of the OFDM signals over the whole considered RF spectrum (from 5 GHz to 26.5 GHz), both in up-conversion and in down-conversion. The measurements show negligible power penalties, lower than 0.5 dB. Since the proposed scheme can act either as an up- or down-converter, and it is composed by easily integratable devices, two identical structures can be combined on a single integrated platform, sharing a single MLL, to build a compact and efficient UWB transceiver.
Comparative analysis of three dc-dc non-isolated buck converters (2012)

This paper presents a comparative analysis of three dc-dc non-isolated buck converters. For this purpose, a classical buck converter, an interleaved buck converter, and a three-state switching cell (3SSC) buck converter were analyzed. In order to best compare the performance of these topologies, the switching frequency, processed power, current ripple before the filter capacitor, and specification were considered equals for all tested configurations. A modular prototype of 1 kW, 200 Vdc / 60 Vdc was implemented, allowing to easily configure all topologies by just changing the magnetic components. From the experimental results, it was found that all studied converters present some current unbalance, being the less critical in the converter based on 3SSC.
Improved performance of spectrum cartography based on compressive sensing in cognitive radio networks (2013)

Spectrum cartography is the process of constructing a map showing Radio Frequency signal strength over a finite geographical area. Multiple research groups have recently proposed to use spectrum cartography in the context of discovering spectrum holes in space that can be exploited locally in cognitive radio networks. In our novel approach, we exploit the sparsity of primary users in space to formulate the cartography process as a compressive sensing problem. Further, we present a novel algorithm for solving the cartography problem that builds on the well-known Orthogonal Matching Pursuit algorithm. We evaluate the performance of our approach by simulating a cognitive radio network where primary users are low power wireless microphones. Our simulation results show a significant improvement in reconstruction error, in comparison to two existing compressive sensing based methods.
Cannabinoids: New Promising Agents in the Treatment of Neurological Diseases (2014)

Nowadays, Cannabis sativa is considered the most extensively used narcotic. Nevertheless, this fame obscures its traditional employ in native medicine of South Africa, South America, Turkey, Egypt and in many regions of Asia as a therapeutic drug. In fact, the use of compounds containing Cannabis and their introduction in clinical practice is still controversial and strongly limited by unavoidable psychotropic effects. So, overcoming these adverse effects represents the main open question on the utilization of cannabinoids as new drugs for treatment of several pathologies. To date, therapeutic use of cannabinoid extracts is prescribed in patients with glaucoma, in the control of chemotherapy-related vomiting and nausea, for appetite stimulation in patients with anorexia-cachexia syndrome by HIV, and for the treatment of multiple sclerosis symptoms. Recently, researcher efforts are aimed to employ the therapeutic potentials of Cannabis sativa in the modulation of cannabinoid receptor activity within the central nervous system, particularly for the treatment of neurodegenerative diseases, as well as psychiatric and non-psychiatric disorders. This review evaluates the most recent available data on cannabinoids utilization in experimental and clinical studies, and highlights their beneficial effects in the prevention of the main neurological diseases and for the clinical treatment of symptoms with them correlated.
Combinatorial synthesis and evaluation of epitaxial ferroelectric device libraries (1998)

Combinatorial libraries of parallel-plate capacitors, consisting of Pt and La0.5Sr0.5CoO3 electrodes and a doped BaxSr1−xTiO3 dielectric layer, have been fabricated and analyzed to systematically study the effects of dopants on device performance. Epitaxial heterostructure libraries with sharp interfaces were generated from amorphous layers on LaAlO3 substrates. Two hundred and forty different host/dopant combinations were synthesized on a 1/2 in. by 1/2 in. substrate, with 23 capacitors for each combination. Addition of 1.5 mol % W was found to increase the figure of merit (ε/Ileak) 220-fold and reduce the high-frequency (MHz and GHz) loss tangent by fourfold.
Detection of<i>Helicobacter pylori</i>Gene by Means of Immunomagnetic Separation-Based Polymerase Chain Reaction in Feces (1998)

This study confirms that non-invasive diagnosis of H. pylori infection could be made from feces by using IMS-based PCR.
Molecular archaeology of the <i>Escherichia coli</i> genome (1998)

The availability of the complete sequence of Escherichia coli strain MG1655 provides the first opportunity to assess the overall impact of horizontal genetic transfer on the evolution of bacterial genomes. We found that 755 of 4,288 ORFs (547.8 kb) have been introduced into the E. coli genome in at least 234 lateral transfer events since this species diverged from the Salmonella lineage 100 million years (Myr) ago. The average age of introduced genes was 14.4 Myr, yielding a rate of transfer 16 kb/Myr/lineage since divergence. Although most of the acquired genes subsequently were deleted, the sequences that have persisted ( approximately 18% of the current chromosome) have conferred properties permitting E. coli to explore otherwise unreachable ecological niches.
Dermatologic Findings in Anorexia and Bulimia Nervosa of Childhood and Adolescence (1999)

The cutaneous signs of anorexia nervosa (AN) and bulimia nervosa (BN) have been described previously in adult patients. For the first time, we present here dermatologic findings in children and adolescents suffering from eating disorders. Thirty consecutive young anorexic and bulimic inpatients (8 to 17 years of age, mean 15.1 years) underwent a standardized dermatologic examination. Patients were checked for abnormalities of the skin including atopic stigmata, dermographism, hair, nails, and oral cavity. Serum was obtained for hemoglobin, iron, zinc, GPT, thyroid, and sex-hormone levels. In 13 patients, the total serum IgE was determined, and a prick test was carried out with defined type I allergens. Findings in order of frequency included xerosis of the skin, white dermographism, diffuse hypertrichosis, acrocyanosis, scars, diffuse effluvium, artifacts, brittle nails, and onychophagia. Significant co-relations were found between the presence of hypertrichosis and the existence of amenorrhea or a body mass index of less than 16. In 22 patients a low T3 level was found. In summary, children and adolescents suffering from AN or BN show dermatologic features similar to those reported in older patients. Special findings in this age group are extensive lanugo hair and signs of autoaggressive behavior.
An Agenda for Facilities Management Research (1992)

Presents an agenda for facilities management research by proposing a framework of key organization, human, environment and economic variables and suggests that research should focus on the links that may be found between them, to generate theory and inform practice. Emphasizes the importance of relating facilities considerations to organizational objectives, and proposes that research should contribute to the development of facilities quality management systems. Maps current research at the Centre for Facilities Management against this framework and identifies progress in understanding the links between facilities and “business” success. Introduces a series of papers that illustrate the integrated research programme being carried out at the Centre.
A Combined Multi:scale Deep Learning and Random Forests Approach for Direct Left Ventricular Volumes Estimation in 3D Echocardiography (2016)

The experiments results suggested that our proposed method is feasible and can achieve higher accuracy, even in case of echocardiography images with irregular geometry.
Machine-Learning-Based Side-Channel Evaluation of Elliptic-Curve Cryptographic FPGA Processor (2018)

Security of embedded systems is the need of the hour. A mathematically secure algorithm runs on a cryptographic chip on these systems, but secret private data can be at risk due to side-channel leakage information. This research focuses on retrieving secret-key information, by performing machine-learning-based analysis on leaked power-consumption signals, from Field Programmable Gate Array (FPGA) implementation of the elliptic-curve algorithm captured from a Kintex-7 FPGA chip while the elliptic-curve cryptography (ECC) algorithm is running on it. This paper formalizes the methodology for preparing an input dataset for further analysis using machine-learning-based techniques to classify the secret-key bits. Research results reveal how pre-processing filters improve the classification accuracy in certain cases, and show how various signal properties can provide accurate secret classification with a smaller feature dataset. The results further show the parameter tuning and the amount of time required for building the machine-learning models.
Adaptive OSEK Network Management for in-vehicle network fault detection (2007)

Rapid growth in the deployment of networked electronic control units (ECUs) and enhanced software features within automotive vehicles has occurred over the past two decades. This inevitably results in difficulties and complexity in in-vehicle network fault diagnostics. To overcome these problems, a framework for on-board in-vehicle network diagnostics has been proposed and its concept has previously been demonstrated through experiments. This paper presents a further implementation of network fault detection within the framework. Adaptive OSEK Network Management, a new technique for detecting network level faults, is presented. It is demonstrated in this paper that this technique provides more accurate fault detection and the capability to cover more fault scenarios.
How two-dimensional bending can extraordinarily stiffen thin sheets (2016)

Curved thin sheets are ubiquitously found in nature and manmade structures from macro- to nanoscale. Within the framework of classical thin plate theory, the stiffness of thin sheets is independent of its bending state for small deflections. This assumption, however, goes against intuition. Simple experiments with a cantilever sheet made of paper show that the cantilever stiffness largely increases with small amounts of transversal curvature. We here demonstrate by using simple geometric arguments that thin sheets subject to two-dimensional bending necessarily develop internal stresses. The coupling between the internal stresses and the bending moments can increase the stiffness of the plate by several times. We develop a theory that describes the stiffness of curved thin sheets with simple equations in terms of the longitudinal and transversal curvatures. The theory predicts experimental results with a macroscopic cantilever sheet as well as numerical simulations by the finite element method. The results shed new light on plant and insect wing biomechanics and provide an easy route to engineer micro- and nanomechanical structures based on thin materials with extraordinary stiffness tunability.
Disambiguation and Error Resolution in Call Transcripts (2019)

Ambiguity is inherent to human language and poses a unique challenge both to human listeners as well as natural language processing (NLP) systems. Ambiguity is understood as a type of uncertainty which allows for more than one plausible interpretation of utterances. Ambiguity can introduce problems for NLP systems designed to, for example, execute machine translation, determine sentiment, and perform automatic speech recognition (ASR). We seek to identify and resolve mis-transcriptions that arise from phonetic ambiguity and degraded acoustic signals in 87,000 call transcripts. We first present an alignment algorithm which identifies mis-transcriptions generated by ASR systems when compared against verified human transcriptions. This method not only allows for a general evaluation of ASR performance but also highlights specific areas of difficulty for such systems (e.g. “considerate” vs. “consider it”). We further present an error resolution algorithm which, given a mis-transcribed word, uses contextual cues to suggest a more likely, phonetically similar word. This work has the potential to not only evaluate existing ASR systems, but also to immediately improve their performance.
Central neurofibromatosis with bilateral acoustic neuroma (1980)

Neurofibromatosis includes the common "peripheral" form and a recently documented "central" form. We describe the central form in 130 cases from 9 kindreds personally studied and 15 reported kindreds. Central neurofibromatosis with bilateral acoustic neuroma is an autosomal dominant disorder beginning about 20 years of age, accompanied by mild skin changes. In three kindreds with central neurofibromatosis, we measured nerve growth factor in serum by radioimmunoassay and radioreceptor assay. Only the antigenic activity of nerve growth factor was increased. In contrast, in peripheral neurofibromatosis, only the functional activity of nerve growth factor has been reported increased. Central and peripheral forms of neurofibromatosis are closely related but discrete diseases which appear to have separate alterations in nerve growth factor activity.
Changes in coagulation condition, cytokine, adhesion molecule after repair of type A aortic dissection (2004)

Hypercoagulation conditions continued even after repair. Both TAT and D-dimer would be good indices for following up patients having repaired aortic dissections. Furthermore, cytokine, adhesion molecules, and collagen turnover would return to a stable state unless impairment and expansion of the vessel wall occurred.
