Abstract:
The paper addresses time and temperature zero drifts in Zeeman laser gyroscope (RLG) operating in the mode of periodic adjustment of RLG to the longitudinal mode of generation with the opposite circular polarization of the light wave. In such a gyroscope, the zero drift can be divided into magnetic and non-magnetic components having different nature and making a significantly different contribution to the final error. Algorithmic methods are proposed for mathematical compensation of RLG zero drift, both with and without using initial calibration. It is shown that the simultaneous use of reproducible dependencies of the magnetic and non-magnetic zero drifts due to RLG temperature changes allows solving the problem of RLG zero drift correction in the optimal way. The correction factors are calculated from the temperature of a Zeeman laser gyro at the moment of activation. At the same time, using the difference between the temperatures of the gyroscope and gyro case, where it is installed, it is possible to determine the temperature of the Zeeman laser gyroscope at the moment of switching on, thereby eliminating the problem of calculating the correction factors when the gyroscope is turned off and then on again. Experimental results for several Zeeman laser gyroscopes with typical values of zero drifts are presented

Abstract:
This article focuses on the long-term drifts of hydraulic pressure gauges, which are constantly subjected to high pressures. A target measurement pressure was consistently applied to pressure gauges for more than two months, and the gauges were occasionally calibrated against a reference pressure balance. The long-term drift has been evaluated based on the variations in calibration values with the elapsed time since the pressure application. We evaluated the long-term drift of three kinds of pressure gauges that are commonly used for calibrations and industrial measurements. The long-term drift differed depending on the type of sensing structure. Although the gauges that had similar sensing structures showed similar drift when the gauges were pressurised due to atmospheric pressure, the amount of the drift depended on each product. In addition, the long-term drift was also affected significantly by the preliminary pressure conditions, even under the same pressure application. Preliminary or ex-post evaluations are necessary for the respective gauges under similar pressure conditions. In practice, the drift of zero-reading is often the main contributory factor of the drift; therefore, the drift can be mitigated by tracing the zero-reading during the pressure applications

The paper describes the physical causes of zero drift and its dependence on temperature. To reveal the temperature dependence of the drift at different heating dynamics, experiments were carried out with different switching intervals. The correlations between the drift and temperature are studied for different switching intervals at a number of significant time points from the switching. A method of drift compensation at different heating dynamics is proposed, which determines the interval closest to the current temperature dynamics

Abstract:
To deal with the AB data with zero-point drift, Swanson and Schlamminger have proposed a filter method to remove the drift of any desired polynomial order, and then give the best linear unbiased estimator of the observable, on the condition that the order of drift is known. Since this method directly removes the drift, one can not know the tendency of the systematic error. This paper proposes to construct a semiparametric regression model for the data, and then take the penalized least squares method to estimate the observable and the drift tendency simultaneously. Simulation analysis shows that the semiparametric method can reach the same accuracy of the filter method, and the estimation of the drift fits well with its actual value.

Abstract OBJECTIVE Intraparenchymal monitoring devices play an important role in the daily management of head injury and other critically ill neurosurgical patients. Although zero drift data exist for the Camino system (Camino Laboratories, San Diego, CA), only in vitro data exist for the Codman system (Codman and Shurtleff, Inc., Raynham, MA). The aim of this study was to assess the extent of zero drift for the Codman intracranial pressure (ICP) monitor in patients being monitored in 2 neurointensive care units. METHODS This was a prospective study conducted at 2 neurointensive care units. Eighty-eight patients who required ICP monitoring and who presented to the 2 neurosurgical departments, Center 1 (n = 48) and Center 2 (n = 40), were recruited for participation. The duration of ICP monitoring was noted, as was the resultant pressure reading in normal saline on removing the ICP monitor (zero drift). RESULTS The median absolute zero drift for the group was 2.0 mm Hg (interquartile range, 1–3 mm Hg). The median time in situ was 108 hours (interquartile range, 69–201 hours). There was a positive correlation between the drift and time of the probe spent in situ (Spearman's correlation coefficient = 0.342; P = 0.001). Of the readings, 20 and 2% showed a drift greater than 5 and 10 mm Hg in magnitude, respectively. CONCLUSION These data demonstrate that a small amount of zero drift exists in ICP monitors and that this drift increases with time. The wide range in the data demonstrates that some drift readings are quite excessive. This reinforces the school of thought that, although ICP readings contribute significantly to the management of neurosurgical patients, they should be interpreted carefully and in conjunction with clinical and radiological assessment of patients.

Abstract:
The maximum drawdown at time T of a random process on [0,T] can be defined informally as the largest drop from a peak to a trough. In this paper, we investigate the behaviour of this statistic for a Brownian motion with drift. In particular, we give an infinite series representation of its distribution and consider its expected value. When the drift is zero, we give an analytic expression for the expected value, and for nonzero drift, we give an infinite series representation. For all cases, we compute the limiting (T → ∞) behaviour, which can be logarithmic (for positive drift), square root (for zero drift) or linear (for negative drift).

Abstract:
Inertial wearable sensors constitute a booming industry. They are self contained, low powered and highly miniaturized. They allow for remote or self monitoring of health-related parameters. When used to obtain 3-D position, velocity and orientation information, research has shown that it is possible to draw conclusion about issues such as fall risk, Parkinson disease and gait assessment. A key issues in extracting information from accelerometers and gyroscopes is the fusion of their noisy data to allow accurate assessment of the disease. This, so far, is an unsolved problem. Typically, a Kalman filter or its nonlinear, non-Gaussian version are implemented for estimating attitude â?? which in turn is critical for position estimation. However, sampling rates and large state vectors required make them unacceptable for the limited-capacity batteries of low-cost wearable sensors. The low-computation cost complementary filter has recently been re-emerging as the algorithm for attitude estimation. We employ it with a heuristic drift elimination method that is shown to remove, almost entirely, the drift caused by the gyroscope and hence generate a fairly accurate attitude and drift-eliminated position estimate. Inertial sensor data is obtained from the 10-axis SP-10C sensor, attached to a wearable insole that is inserted in the shoe. Data is obtained from walking in a structured indoor environment in Votey Hall.

Abstract:
La thèse se propose d’analyser la nature des relations générées entre le pouvoir des sociétés multinationales et transnationales et les Etats, afin de rechercher l’ensemble des obligations internationales impliquées concernant les droits de l'homme et, plus spécifiquement, celles relatives au droit universel à la santé. En effet, il est de plus en plus évident que les sociétés transnationales sont en mesure de causer des risques considérables, susceptibles de provoquer des conséquences néfastes sur le droit à la santé des individus, ou bien encore, sur les « déterminants de la santé ». À la lumière de ces considérations et en constatant l’ampleur de la problématique, la thèse se focalise sur les obligations spécifiques liées aux secteurs de l’industrie pharmaceutique, des compagnies de tabac et des multinationales du secteur alimentaire. Le travail de recherche a été rédigé selon les critères académiques utilisés classiquement en Italie et est fondée sur un argumentaire articulé en trois chapitres principaux, une introduction et une conclusion finale
The thesis aims to analyse the nature of the relationships generated between the power of multinational and transnational corporations and States, in order to identify all the international human rights obligations involved and more specifically, those relating to the universal right to health. According to the economic system established by the Western Countries and the globalization, transnational corporations are able to cause considerable risks, which may have adverse consequences on the Human Right to Health, or even “determinants of health”. In the light of these considerations and due to the extent of the issue, the thesis has been focused on the analysis of specific obligations related to the sectors of pharmaceutical industries, the tobacco corporations and the multinational food companies. The thesis was written according to the academic criteria traditionally used in Italy and is based on argumentation articulated in three main chapters, an introduction and a final conclusion
Il proposito della tesi è quello di offrire un’indagine accurata concernente la natura delle relazioni che si generano tra il potere delle imprese transnazionali e le autorità statali, della trama degli obblighi internazionali implicati, in modo particolare alla luce di violazioni di diritti umani che potrebbero generarsi. Il liberalismo economico, la promozione degli scambi con relativo abbattimento delle barriere territoriali, il mercato globale hanno condotto al generarsi di formazioni industriali globalizzate con forze economiche tali da influenzare gli assetti politici di un Paese, andando dunque ben oltre le funzioni specifiche di mera produzione e immissione sul mercato dei propri prodotti. Preliminarmente, è interessante capire come la dottrina internazionalistica affronta e definisce le perplessità relative alla configurazione di una soggettività di diritto internazionale “eccezionalmente riconosciuta”, che poi costituirà la base per le riflessioni a venire. La prima riguarda la transnazionalità dell’impresa. Questa peculiarità costitutiva, figlia del mercato globalizzato, consente al meccanismo del sistema produttivo di sottrarre un’unità specifica dalla riconduzione territoriale della cd. Casa madre, pur restandone parte integrante.Lo stato dell’arte del diritto internazionale prevede, in capo all’autorità statale ospitante, un obbligo incombente di regolamentazione e controllo dell’attività svolta dalle imprese sul proprio territorio. Tuttavia, nella prassi si riscontrano circostanze di Stati deboli dal punto di vista legislativo, con carenti strumenti di tutela e scarse risorse, tali da renderli proprio per questo, mete ideali di soggetti investitori che intendono eludere le più rigide disposizioni vigenti nei propri Paesi di origine.Il ruolo delle società multinazionali oggi, di quelle transnazionali in particolare per alcuni, consente di poter ridiscutere dei capisaldi di un diritto internazionale definito stato-centrico e della propria capacità di riuscire a rispondere alle esigenze dei tempi correnti. Se è vero che il diritto internazionale nasce con il precipuo scopo di regolare i rapporti tra Stati, ai quali viene attribuita un’esclusiva personalità giuridica che li rende idonei ad essere titolari di diritti e obblighi giuridici, nella prassi delle relazioni emerge una realtà molto più complessa di questa.L’istituzione dell’Open Ended Intergovernmental Working Group che proseguono il lavoro del Relatore Speciale, il Professor Ruggie, lascia trasparire quanto il tema sia al centro dello sviluppo sui diritti umani della Nazioni Unite. Sulla stessa linea si sta sviluppando una legislazione anche in seno al Consiglio d’Europa con l’adozione della raccomandazione CM/Rec (2016)3 del novembre 2016, nonché in UE con la direttiva 2014/95/UE sull’obbligo di pubblicazione delle informazioni non finanziarie.Alla luce di tali circostanze, la tesi analizza il tema specifico della responsabilità delle imprese transnazionali in materia di rispetto e promozione del diritto alla salute e dei suoi determinanti, a fronte della diffusione epidemica delle malattie non trasmissibili. Per questo il lavoro di ricerca si concentra sugli obblighi specifici relativi ai settori delle imprese farmaceutiche, produzione e commercializzazione di tabacco, food corporations

This thesis designs an integrator to measure the dc components of the direct coupled amplifier and feedback to the amplifier input node to suppress the zero-point drift so that there is no dc component at the amplifier output. The proposed circuits can not only sense the zero-drift of the amplifier but also dynamically compensate the level shift preventing feedback circulation from causing parts burning. The simulation and experimental results illustrate the integrator circuit with the ability to suppress the zero drift of the direct coupled amplifier that increase the lower frequency response from 504 Hz to 9 Hz.

Abstract:
Many models of phasor measurement units (PMU) have been implemented; however, few dynamic models have been developed when the power system parameters change. It is necessary to use a method that can somehow estimate the frequency and correct the phasors. The conventional way to determine frequency is to detect zero crossings per unit time. However, this method has many drawbacks such as high cost and low accuracy. Also, after the frequency determination, the phasor should be corrected by suitably modifying the algorithm without omitting any data. This chapter presents different estimation techniques such as discrete Fourier transform (DFT), smart discrete Fourier transform (SDFT) that may be used to estimate the phasors. These estimated values would be incorrect if the input signals are at an off-nominal frequency and the phase angles would drift away from the true values. To correct this issue, first of all, the off-nominal frequency has been estimated using different techniques such as least error squares and phasor measurement angle changing, and then it is used to correct the phasors.

In this chapter the authors evaluate a new and promising solution to the problem of power consumption based on “optimum gate biasing.” This technique consists in tracking the MOS operating region wherein the third derivation of drain current is zero. The method leads to a significant IIP3 improvement; however, the sensitivity to process drifts requires the use of a specific bias circuit to track the optimum biasing condition.

Abstract:
The purpose of respiratory gas analysis during anaesthesia is to identify and measure the concentrations, on a breath by breath basis, of the individual gases and vapours in use. It may also be useful as a guide to cardiac function or to identify trace contaminant gases. Different techniques use different physicochemical properties of the gas or vapour. An understanding of the physical principle underlying each method is necessary in order to recognise the value and limitations of each. In terms of the device’s ability to respond on a breath by breath basis, there are two important components: the time taken for the gas to be sampled from the anaesthetic machine or breathing system, the delay time; then there is the time taken for the device to measure the gas concentration, the response time. This is depicted in Figure 16.1. Most of the delay occurs in the delay time or transit time and can be reduced either by analysing the gas sample close to the airway, or by using as short and thin a sampling tube and as high a sampling flow rate to the analyser as possible [Chan et al. 2003]; the sampling flow rate is usually of the order of 100 to 200 ml min−1. If minimal fresh gas flow rates are being used in a circle anaesthetic breathing system and the sampled gas is not returned to the breathing system, then a high gas sampling rate could represent a significant gas leak. Figure 16.1 shows a sigmoid curve of recorded gas concentration change in response to a square wave input change. The response of a gas analyser is often expressed as the time taken to produce a 90–95% response to a step or square wave input change. A square wave change in gas concentration can be produced by moving a gas sampling tube rapidly into and out of a gas stream, by bursting a small balloon within a sampling volume containing a gas sample, or by switching a shutter to a gas sample volume using a solenoid valve. An important part of the use of gas analysers is zeroing and calibration since they are all prone to drift in both zero and gain.

Abstract:
ACME facility (Advanced Core-cooling Mechanism Experiment) is a large-scale test facility used to validate the performance of passive core-cooling system under SBLOCA (Small Break Lost of Coolant Accident) for the CAP1400, an upgraded passive safety nuclear power plant of AP1000. To simulate the features of passive safety system properly, DELTABAR, a kind of differential pressure flow meter, is designed to measure different mass flow of ACME. Because of the low pressure loss of DELTABAR, Zero-Drift problem of differential pressure flow meters in ACME is amplified, and some of the measured values are distorted seriously. To minimize the influence of Zero-Drift, analysis on zero-drift phenomenon is made, and a compensation method is proposed. The method is applying to PBL flow meters, and the result shows that the method is applicable.

Abstract:
Invasive zebra mussels (Dreissena polymorpha) were first observed in situ at Apostle Islands National Lakeshore (APIS) in 2015. This report builds on 2018 SCUBA surveys and Environmental Protection Agency (EPA) veliger sampling to: 1) determine whether shoals on APIS borders act as sentinel sites to corroborate veliger drift hypotheses about invasion pathways, 2) evaluate ongoing hand-removal of zebra mussels from easily identified structures, and 3) continue efforts to assess native unionid mussel populations, particularly where zebra mussels are also present. Standard catch per unit effort survey methods by SCUBA teams were used to determine the distribution and relative abundance of zebra or quagga mussels (dreissenids) and native mussels (unionids). Zebra mussels were present at densities between 3 and 42 n/diver/hr (number of mussels per diver per hour), while native unionids were present at densities between 5 and 72 n/diver/hr. Shoal surveys (Eagle Island shoal, Sand Island shoal, York Island shoal, Bear Island shoal, Oak Island shoal, and Gull Island shoal) showed zebra mussels were more abundant on the west side of APIS and absent on the easternmost shoal (Gull Island), corroborating veliger work by the EPA that suggested drift from the Twin Ports of Duluth, Minnesota, and Superior, Wisconsin, is one pathway of invasion. Our results support the use of shallow shoals along the periphery of the park as sentinel sites gauging zebra mussel immigration and population dynamics. Zebra mussel densities in the central islands showed no obvious spatial pattern, and this survey cannot determine whether currents or human transport (or both) are invasion vectors. Given the mussels’ continued presence at heavily used mooring areas and docks where there are no zebra mussels on nearby natural features (e.g., Rocky Island dock, Stockton Island mooring areas), our findings are consistent with multiple invasion pathways (drift from the Twin Ports and anthropogenic sources at mooring areas). SCUBA search and removal of zebra mussels from docks was confirmed to be an effective method for significantly lowering the risk of zebra mussels reproducing and dispersing from these locations. We caution that this work is being done on what look like initial invasions at low densities. Repeated removal of zebra mussels by divers reduced numbers to zero at some sites after one year (South Twin docks, Stockton Island NPS docks, and the Ottawa wreck) or decreased numbers by an order of magnitude (Rocky Island docks). Dreissenid densities were more persistent on the Sevona wreck and longer-term work is required to evaluate removal versus recruitment (local and/or veliger drift). Given the size of the wreck, we have tracked detailed survey maps to guide future efforts. Zebra mussels were again observed attached to native mussels near Stockton Island and South Twin Island. Their continued presence on sensitive native species is of concern. Native unionid mussels were more widely distributed in the park than previously known, with new beds found near Oak and Basswood Islands. The work reported here will form the basis for continued efforts to determine the optimal frequency of zebra mussel removal for effective control, as well as evaluate impacts on native species.
