Bioresorbable scaffolds (BRSs) were introduced to overcome the limitations of metallic stents associated with permanent caging of the arterial wall. The expected advantages were restoration of vessel physiology, and elimination of a permanent foreign body carrying long-term risks of device-related adverse events, including restenosis and stent thrombosis. However, after initial enthusiasm, real-world registries reported disturbingly high rates of scaffold thrombosis. In order to overcome the limitations in scaffold design (very thick struts) and suboptimal mechanical properties (lower radial force), aggravated by the very long degradation rate, the use of intracoronary imaging techniques has been strongly recommended. Because of its higher resolution, optical coherence tomography (OCT) provides detailed and precise morphologic information of BRS than intravascular ultrasound (IVUS) and has been largely applied for the assessment of acute post-procedural and long-term outcome. OCT played a central role in the detection of structural abnormalities leading to scaffold thrombosis, and optimization of BRS implantation under OCT guidance has been strongly advocated to mitigate scaffold failures. Moreover, OCT provided crucial information about the long-term vascular healing response after implantation and identified factors potentially influencing the resorption process. This chapter examines the clinical application of OCT for the assessment of BRS.

Hydrocarbon seepage is overlooked in the marine environment, mostly due to lack of marine exploration data, especially over the continental shelf and upper slope, where data may be available but not at adequate resolution. Shallow marine environments, such as the north and the central Adriatic Sea, are ideal for the formation of hydrocarbons, because organic matter sinks to the sea bottom where undergoes rapid burial and anaerobic degradation. On the other hand, deeply-trapped hydrocarbons tend to migrate to shallower sedimentary horizons, they may pierce the seabed, giving rise to peculiar seafloor morphology, and, under particular conditions, fluids escape the seabed to form gas plumes in the water column. The latter can be accurately detected by modern multibeam sonar systems as 3D density anomalies, which sometimes can reach high at the sea surface. This contribution is about the geophysical and geochemical investigation of two seepage sites on the shelf of the Adriatic Sea. The study areas are represented by: an oil spill off Civitanova Marche, at water depth of 10 m; scattered biogenic seeps offshore Mt. Conero, at water depth of 84 m. Dissolved benthic fluxes of nutrients, metals and DIC have been measured by in situ deployment of a benthic chamber equipped with an automatic water sampler and a multi-parameter probe. Geochemical analysis was performed to identify the presence of and characterize hydrocarbons in the water samples and provide insights into the origins of the organic matter. Concentration of Polycyclic Aromatic Hydrocarbons and major and trace elements was analyzed to provide an estimate of hydrocarbon contamination in the surrounding sediment. We conducted these research activities under the umbrella of a technical agreement between ISMARCNR and the Italian Ministry of Economic Development, Directorate General for Safety - National Mining Office for Hydrocarbons and Georesources, within the Clypea Innovation Network, which seeks to increase the safety, also in terms of environmental protection, of offshore oil & gas exploration and exploitation, using innovative approaches. This study aims at: i) establishing a cost-effective and relocatable geochemical and geophysical monitoring system for natural hydrocarbon seepage to mitigate the adverse effects of hydrocarbon spill and discharge, especially if located near the coast or nearby human activities; ii) delivering a better understanding of the characteristics and origins of the petroleum system, adding a valuable layer of information to more conventional offshore exploration data; iii) to unravel the relationship of fluid seepage with geohazards, notably softsediment deformation, and sea level changes as triggering mechanism.

Hydrocarbon seepage is overlooked in the marine environment, mostly due to the lack of high-resolution exploration data. This contribution is about the geophysical and geochemical investigation of two seepage sites on the shelf of the Adriatic Sea: an oil spill off Civitanova Marche, at water depth of 10 m; scattered biogenic seeps offshore Mt. Conero, at water depth of 84 m. The accurate detection of gas plumes was achieved with a multibeam system acquisition of the water column reflectivity. Dissolved benthic fluxes of nutrients, metals and DIC were measured by in situ deployment of a benthic chamber, which was used also for the first time as water samples collector for hydrocarbons gas characterization. In addition, concentration of Polycyclic Aromatic Hydrocarbons and major and trace elements was analyzed to provide an estimate of hydrocarbon contamination in the surrounding sediment.

Artificial reefs (ARs) have become popular technological interventions in shallow water environments characterized by soft seabed for a wide number of purposes, from fisheries/environmental protection and enhancement to research and tourism. AR deployment has the potential for causing significant hydrographical and biological changes in the receiving environments and, in turn, ARs are strongly affected by the surrounding area in terms of spatial arrangement and structural integrity as well as colonization by benthic communities and finfish. In this context, ARs require a systematic monitoring program that a multibeam echosounder (MBES) can provide better than other sampling methods such as visual dives and ROV inspections that are not quantitative and often influenced by water visibility and diver experience/skills. In this paper, some subsequent MBES surveys of the Senigallia scientifically-planned AR (Northern Adriatic Sea) are presented and state-of-the art data processing and visualization techniques are used to draw post-reef deployment comparisons and quantify the evolution of the reef in terms of spatial arrangement and bulk volume. These multibeam surveys play a leading part in a general multi-year program, started simultaneously with the AR design and deployment and aimed to map how the reef structure quantitatively changes over time, as well as it affects the sea-bottom morphology and the fishery resource. All the data, surveyed over years making use of different sampling methods such as visual and instrumental echosounding observations and catch rate surveys, gain a mechanistic and predictive understanding of how the Senigallia AR functions ecologically and physically across spatial and temporal scales during its design life

The huge potential of 3D digital acquisition techniques for the documentation of archaeological sites, as well as the related findings, is almost well established. In spite of the variety of available techniques, a sole documentation pipeline cannot be defined a priori because of the diversity of archaeological settings. Stratigraphic archaeological excavations, for example, require a systematic, quick and low cost 3D single-surface documentation because the nature of stratigraphic archaeology compels providing documentary evidence of any excavation phase. Only within a destructive process each single excavation cannot be identified, documented and interpreted and this implies the necessity of a re- examination of the work on field. In this context, this paper describes the methodology, carried out during the last years, to 3D document the Early Neolithic site of Portonovo (Ancona, Italy) and, in particular, its latest step consisting in a photogrammetric aerial survey by means of UAV platform. It completes the previous research delivered in the same site by means of terrestrial laser scanning and close range techniques and sets out different options for further reflection in terms of site coverage, resolution and campaign cost. With the support of a topographic network and a unique reference system, the full documentation of the site is managed in order to detail each excavation phase; besides, the final output proves how the 3D digital methodology can be completely integrated with reasonable costs during the excavation and used to interpret the archaeological context. Further contribution of this work is the comparison between several acquisition techniques (i.e. terrestrial and aerial), which could be useful as decision support system for different archaeological scenarios. The main objectives of the comparison are: i) the evaluation of 3D mapping accuracy from different data sources, ii) the definition of a standard pipeline for different archaeological needs and iii) the provision of different level of detail according to the user needs.

A growing concern about the depletion of marine resources due to fishing overexploitation and degradation of ecosystems has been demonstrated over the last decade. Monitoring the spatial and temporal distribution of fishing activities is an important tool for fisheries management which can also be used by other sectors such as fisheries science, public authorities, policy-makers and marine spatial planning. In this paper we introduce the first map of fishing activity at a Mediterranean scale of EU and non-EU fishing vessels, extracted using Automatic Identification System ship tracking data. Fishing activity maps were produced for three different years with a spatial resolution of 0.01° × 0.01°. As a main result, for the first time, changes of bottom trawl fishing activities between two consecutive years were map for the whole Mediterranean Sea. The results confirmed the suitability of this monitoring system to obtain reliable information on the extent of bottom trawl fishing activities.

Plastic is widely used in everyday life being one of the more versatile materials ever produced. The rising demand of plastic items to support the societal development has dramatically boosted the annual plastic production from 1.5 in the 1950s to 311 million tonnes in 2014 (PlasticEurope in Plastic-the Facts 2015: an analysis of European plastic production, demand, and waste data, 2014). The dark side of the plastic revolution is the marine pollution, with an estimated amount of 9.5 million tonnes of new plastic waste flowing into the oceans each year (Boucher and Friot in Primary microplastics in the oceans: a global evaluation of sources. IUCN, Gland, p. 43, 2017).

Micro-plastic particles in the world's oceans represent a serious threat to both human health and marine ecosystems. Once released into the aquatic environment plastic litter is broken down to smaller pieces through photo-degradation and the physical actions of waves, wind, etc. The resulting particles may become so small that they are readily taken up by fish, crustaceans and mollusks. There is mounting evidence for the uptake of plastic particles by marine organisms that form part of the human food chain and this is driving urgent calls for further and deeper investigations into this pollution issue. The present study aimed at investigating for the first time the occurrence, amount, typology of microplastic litter in the gastrointestinal tract of Solea solea and its spatial distribution in the northern and central Adriatic Sea. This benthic flatfish was selected as it is a species of high commercial interest within the FAO GFCM (General Fisheries Commission for the Mediterranean) area 37 (Mediterranean and Black Sea) where around 15% of the overall global Solea solea production originates. The digestive tract contents of 533 individuals collected in fall during 2014 and 2015 from 60 sampling sites were examined for microplastics. These were recorded in 95% of sampled fish, with more than one microplastic item found in around 80% of the examined specimens. The most commonly found polymers were polyvinyl chloride, polypropylene, polyethylene, polyester, and polyamide, 72% as fragments and 28% as fibers. The mean number of ingested microplastics was 1.73 ± 0.05 items per fish in 2014 and 1.64 ± 0.1 in 2015. PVC and PA showed the highest densities in the northern Adriatic Sea, both inshore and off-shore while PE, PP and PET were more concentrated in coastal areas with the highest values offshore from the port of Rimini. Occurrence and polymeric composition of microplastics in stomach content of wild S. solea is assessed. Spatial distribution is more influenced both by polymers chemical-physical properties and peculiarities in the oceanographic conditions rather than by the feeding strategy of the species.

There is growing evidence supporting a possible role for metabolic syndrome and its determinants, such as dyslipidemia, in uterine fibroid (UF) pathogenesis. The present study aims to investigate the association between UFs and visceral and subcutaneous fat thickness (SFT), lipid profile, and oxidative and antioxidative status. In this cross-sectional study, 35 patients diagnosed with UFs and 15 women without UFs were enrolled. Clinical history and anthropometric parameters were collected for every woman. Characteristics of UFs, preperitoneal fat thickness (PFT), and SFT were assessed ultrasonically. Lipid profile, glucose, thiobarbituric acid reactive substances (TBARs), and superoxide dismutase (SOD) activity were evaluated on plasma from participants. Women with UFs showed a significantly increased PFT (11.63 ± 3.39 vs 7.01 ± 3.10 mm; P

The second Mediterranean Data Adequacy Report (DAR) is completing the development of concepts and methodologies initiated in the Literature Review and in the first Data Adequacy Report. The aim of this DAR is to document the reliability and utility of the existing monitoring system at the sea basin level and it identifies the gaps, prioritizing them. This DAR describes the final methodological approach for the MedSea Checkpoint based upon ISO and INSPIRE principles and the development of indicators. The indicators are constructed directly from the Checkpoint metadatabase, which contains information on the upstream data used to construct the Challenge products. For each Challenge product, Checkpoint information on What, Why, Where, When, How data have been used to develop targeted products is given and statistically analysed.

The targeted products were divided in two main tasks, based on the Challenge 5 Objectives: TASK 1) fishery datasets of fish landings, discard and by-catch (ETP species) for assessing the quality, extracting the synergies and identifying the gaps in the fishery data collection systems in the Mediterranean Sea; TASK 2) maps showing the extent of the trawling fishing grounds in order to identify the areas that have been most disturbed by bottom trawling and the changes in the level of disturbance over the past 10 years. The aim was to identify the gaps in fishing vessels’ tracking systems operating in the Mediterranean Sea and to evaluate the impact of trawling on the seabed. For the first task, the landing, discard and by-catch data were compiled using information gathered from the DCR/DCF, FAO-FishStat and ICCAT databases. For the second task, the impact of trawling on the seabed was estimated using data recorded by the Vessel Monitoring System (VMS), the Automatic Identification System (AIS) and the ESIF system developed within the EU project “Energy Saving in Fisheries”, financed under the framework of the open call for Tenders Fish/2006/17-LOT3. In particular, the ESIF system data were included both as an example of an alternative monitoring system and to validate the VMS and AIS data. Biota-biology and seabed layers (seabed habitats and substrate) were considered to evaluate the impact on sensitive habitats.

The research aims to optimize a workflow of architecture documentation: starting from panoramic photos and tackling available instruments and technologies the aim is to propose an integrated, quick and low-cost solution of Virtual Architecture. The broader research background shows how to use spherical panoramic images for the architectural metric survey. The input data (oriented panoramic photos), the level of reliability and Image-based Modeling methods constitute an integrated and flexible 3D reconstruction approach: from the professional survey of cultural heritage to its communication in virtual museum. The proposed work results from the integration and implementation of different techniques (Multi-Image Spherical Photogrammetry, Structure from Motion, Dense Image Matching and Image-based Modeling) with the aim to achieve high metric accuracy and photorealistic performance. Different documentation chances are possible within the proposed workflow: from the virtual navigation of spherical panoramas to complex solutions of simulation and virtual reconstruction. VR tools make for the integration of different technologies and the development of new solutions for virtual navigation. Image-based Modeling techniques allow 3D model reconstruction with photo realistic and high-resolution texture. High resolution of panoramic photo and algorithms of panorama orientation and photogrammetric restitution vouch high accuracy and high-resolution texture. Automated techniques and their following integration are subject of this research. Data, advisably processed and integrated, provide different levels of analysis and virtual reconstruction joining the photogrammetric accuracy to the photorealistic performance of the shaped surfaces. Lastly, new solutions of heritage interactive and immersive communication are tested as inevitable visualization consequence of previous experimental results.

An electron impact ion source has been fabricated using MEMS technology. The chosen fabrication process allows for manufacturing simultaneously and collectively the ion source and the analyser on the same substrate. A small and compact micro time-of-flight spectrometer is thus structured in a monolithic way in large scale integration (LSI). The fabrication process and the performances of the source, based on the electron impact ionization mechanism, are presented. The ion current can be as high as tens of nano-amps, one of the highest level reported for an integrated source in a micro mass spectrometer. It presents a raw ionization efficiency of 2.5 × 10 −3 . By positioning a fast detector at a few millimeters from the ion source, a simple linear TOF mass spectrometer has been assembled. Promising spectra have been obtained on simple gases like argon.

3D City Models have evolved to be important tools for urban decision processes and information systems, especially in planning, simulation, analysis, documentation and heritage management. On the other hand existing and in use numerical cartography is often not suitable to be used in GIS because not geometrically and topologically correctly structured. The research aim is to 3D structure and organize a numeric cartography for GIS and turn it into CityGML standardized features. The work is framed around a first phase of methodological analysis aimed to underline which existing standard (like ISO and OGC rules) can be used to improve the quality requirement of a cartographic structure. Subsequently, from this technical specifics, it has been investigated the translation in formal contents, using an owner interchange software (SketchUp), to support some guide lines implementations to generate a GIS3D structured in GML3. It has been therefore predisposed a test three-dimensional numerical cartography (scale 1:500, generated from range data captured by 3D laser scanner), tested on its quality according to the previous standard and edited when and where necessary. Cad files and shapefiles are converted into a final 3D model (Google SketchUp model) and then exported into a 3D city model (CityGML LoD1/LoD2). The GIS3D structure has been managed in a GIS environment to run further spatial analysis and energy performance estimate, not achievable in a 2D environment. In particular geometrical building parameters (footprint, volume etc.) are computed and building envelop thermal characteristics are derived from. Lastly, a simulation is carried out to deal with asbestos and home renovating charges and show how the built 3D city model can support municipal managers with risk diagnosis of the present situation and development of strategies for a sustainable redevelop.

The Università Politecnica delle Marche is charged of the study, survey and documentation of the Chan towers in Vietnam. The towers are spread near the coastline from latitude 16° 30', to latitude of 10° 56'. The Champa civilization flourished from 8th century till 17th century produced the Cham towers, places of religious worship. The ancient Cham people created a developed culture expressed in the architecture in the towers, which were Buddhist temples. Roughly there are six different architectonic styles and two different layouts in plan. One lay-out is that one main tower is surrounded by smaller service buildings, like walls, doors, gates; the other layout is a set of three aligned towers. We carried out the documentation with three different techniques, laser scanning, dense point clouds generation with SfM (Structure from Motion) algorithm, and mainly by Panoramic Spherical Photogrammetry (PSP). Laser scanning is indeed the best instrument but sometimes its availability is very limited for different practical and logistic reasons. The point cloud generation produced good results, but it has some problems and limitations of management too. On the other hand PSP is very quick technique in the taking phase, but the restitution is rather slow. PSP is suitable for a good metric documentation, making the Cham tower project the main project of documentation executed with spherical photogrammetry.

Multidisciplinary monitoring of the impact of offshore gas platforms on northern and central Adriatic marine ecosystems has been conducted since 1998. Beginning in 2006, 4-5 year investigations spanning the period before, during, and after rig installation have explored the effects of its construction and presence on macrozoobenthic communities, sediment, water quality, pollutant bioaccumulation, and fish assemblages. In this study, sediment samples collected at increasing distance from an offshore gas platform before, during and after its construction were subjected to chemical analysis and assessment of benthic communities. Ecological indices were calculated to evaluate the ecological status of the area. Ecotoxicological analysis of sediment was performed to establish whether pollutants are transferred to biota. The study applied a before-after control-impact design to assess the effects of rig construction and presence and provide reference data on the possible impacts of any further expansion of the gas extraction industry in the already heavily exploited Adriatic Sea. Only some of the metals investigated (barium, chromium, cadmium, and zinc) showed a different spatial and/or temporal distribution that may be platform-related. In the early phases, the sediment concentrations of polycyclic aromatic hydrocarbons were below the detection limit at all sites; they then became detectable, but without significant spatial differences. The present findings suggest that the environmental effects of offshore gas platforms may be difficult to quantify, interpret, and generalize, because they are influenced by numerous, often local, abiotic, and biotic variables in different and unpredictable ways.

A stark difference in the electrical, optical and thermal properties of an atmospheric pressure plasma jet source exploiting spark discharges in a gas stream was reported when argon is used instead of air in the flow. Electrical probe results are discussed together with optical ones in order to investigate the discharge properties and the temporal structure of the different pulses of electrical current. If air-argon mixtures are used as feeding gas for the discharge, a sharp transition from a hot plume to a cold plasma jet is observed when argon content exceeds 90 %. Characteristics of the source are examined from the point of view of their utility as a tool for plasma treatment of materials. In this respect, a 10 % air in argon mixture corresponds to a promising oxidizing condition, as revealed by the pronounced peak in atomic oxygen emission intensity.

This work shows the optimization, both by simulations and experimentally of the ion source optics of a miniaturized time-of-flight mass spectrometer. The simulations are used to speed up the experiments and make them more efficient in finding optimal working points. The experimental points agree well with simulations. The ion source is used finally as a linear micro time-of-flight mass spectrometer. Simple gas mixtures are identified efficiently using this system.

Occurrence and distribution of the sea pens Virgularia mirabilis and Funiculina quadrangularis in the northern and central Adriatic Sea were determined from data collected during five trawl surveys from 2011 to 2015 carried out through rapido trawl. Species density data (number of individuals per km ) were processed to describe their spatial distribution.

Traditionally, remote sensing has employed pixel-based classification techniques to deal with land use/land cover (LULC) studies. Generally, pixel-based approaches have been proven to work well with low spatial resolution imagery (e.g. Landsat or System Pour L'Observation de la Terre sensors). Now, however, commercially available high spatial resolution images (e.g. aerial Leica ADS40 and Vexcel UltraCam sensors, and satellite IKONOS, Quickbird, GeoEye and WorldView sensors) can be problematic for pixel-based analysis due to their tendency to oversample the scene. This is driving research towards object-based approaches. This article proposes a hybrid classification method with the aim of incorporating the advantages of supervised pixel-based classification into object-based approaches. The method has been developed for medium-scale (1:10,000) LULC mapping using ADS40 imagery with 1 m ground sampling distance. First, spatial information is incorporated into a pixel-based classification (AdaBoost classifier) by means of additional texture features (Haralick, Gabor, Law features), which can be selected 'ad hoc' according to optimal training samples ('Relief-F' approach, Mahalanobis distances). Then a rule-based approach sorts segmented regions into thematic CORINE Land Cover classes in terms of membership class percentages (a modified Winner-Takes-All approach) and shape parameters. Finally, ancillary data (roads, rivers, etc.) are exploited to increase classification accuracy. The experimental results show that the proposed hybrid approach allows the extraction of more LULC classes than conventional pixel-based methods, while improving classification accuracy considerably. A second contribution of this article is the assessment of classification reliability by implementing a stability map, in addition to confusion matrices.

The choice of the best classification approach for thematic map generation relies on many factors, such as image resolution and minimum mapping unit. The generalized GIS-ready products derived from the results of pixel-based approaches and the availability of higher-resolution imagery have directed research towards object-based classification approaches. In this paper we present the superior performance of a hybrid methodology that combines the results of automatic segmentation with the land cover information derived from a pixel classification by means of the Winner Takes All (WTA) algorithm. Land use and land cover results obtained through this hybrid classification approach are compared with those of a One Against All (OAA) object-oriented classification approach.

The aim of this multicenter, randomized, prospective study was to reveal a difference in terms of a guided healing period in the case of stoma orifices after reestablishing digestive continuity by comparing an alginate mesh with a polyvidone iodine mesh.Between April 2004 and September 2005, a total of 73 patients were randomized into two groups: A (alginate mesh) and M (polyvidone iodine mesh). The groups were comparable for demographic data, indications for and the type of stoma, and perioperative data. The main evaluation criterion was percentage healing at the 28th postoperative day (D28); and the secondary criteria were healing time, rate of infectious complications, and number of dressing changes applied.The mean percentage healing at D28 was 91% in group A and 87% in group M (p = 0.49). The mean healing time was 31 days in group A and 32 days in group M (p = 0.80). One parietal abscess (3%) occurred in group A (p = 0.37). The mean number of meshes used was 13 +/- 5 in group A and 18 +/- 8 in group M (p0.005).The use of an alginate mesh for guided healing of stoma orifices after reestablishing digestive continuity allows effective healing within a normal period of time with a lower number of meshes.

There is consensus on the need for in-service buckling analyses to assess the integrity of both flowlines and long distance trunklines subject to HP/HT service condition. The extent of the analyses and supporting survey depends on the severity of the application. In the last two decades, the pipeline industry has gained significant experience in both the design and operation of pipeline systems exposed to global buckling. Actually, the early 90s have been a watershed: before the phenomenon was just known (theoretically), then it was seen...as soon as pipeline integrity management programmes have been introduced in the offshore pipeline industry practices. Although, limited information have been documented in the open literature, now as then. Several efforts have been dedicated to develop design methods and procedures suitable for operating pipeline safely as well as protecting the population, environmental resources and assets. At the beginning, there was a gap to be closed as specific mitigation measures were never designed. Nowadays, thanks to computational progress, it seems that the attention is addressed to face the uncertainties affecting the subject matter but, sometime, leading to overdesign. The scope of the paper is to present aspects of global buckling design analyses that were performed in recent projects with the aim to highlight the challenges and the risks, the accuracy or the limitation of the methods, the feedback and the lesson learnt of real installed pipelines under operating conditions.

Multibeam Echosounder (MBES) is increasingly becoming suitable for marine habitat mapping and various classification methods, diversifying in terms of classification algorithms, automation and MBES involved data features, are requiring scientific attention. On the other hand, the improved quality and volume of MBES data, as well as the increased demand for mapping products, is driving the desire for repeatable seafloor mapping approaches, analogous to the automated classification of satellite imagery in terrestrial remote sensing. In this context, the proposed study deals with Kongsberg EM3002D data and investigates how to tailor a proprietary hybrid classification approach, successfully developed for terrestrial Land Cover mapping, to seafloor characterization. Dataset includes full-coverage bathymetry, backscatter intensity and their derived textural / statistical features. Concurrent clam fisheries surveys (striped venus Chamelea gallina) give the chance to carry out sample-specific quantitative correlations and investigate how shellfish beds can affect MBES backscatter and consequently be used to detail the seafloor characterization. Experimental results show how to improve the overall acoustic seabed classification first integrating MBES data along with their derivatives and later combining information at both pixel and object level to detail the seafloor map legend in terms of probable presence of clams. The final habitat data is GIS-ready, hence suitable to be directly used for marine spatial/temporal planning and resource management.

This paper presents an original method for the modeling of microcoils at high frequency dedicated for different applications: radio frequency, nuclear magnetic resonance, nondestructive testing, etc. The aim of the modeling is to determine the elements of an electric equivalent circuit. A magneto-dynamic three-dimensional (3-D) finite-element formulation is used to calculate the resistance and the inductance of the microcoil at high frequency. Using the previous results, an electrostatic 3-D finite-element field analysis is then used to determine the capacitance. The method was tested by using an example of nuclear magnetic resonance microcoil. Numerical results obtained by the proposed method are compared with measurements and analytical results.
