Abstract:
A novel method for evolutionary material development by using high-throughput processing is established. For the purpose of this high-throughput approach, spherical micro samples are used, which have to be characterized, up-scaled to macro level and valued. For the evaluation of the microstructural state of the micro samples and the associated micro-properties, fast characterization methods based on physical testing methods such as calorimetry and universal microhardness measurements are developed. Those measurements result in so-called descriptors. The increase in throughput during calorimetric characterization using differential scanning calorimetry is achieved by accelerating the heating rate. Consequently, descriptors are basically measured in a non-equilibrium state. The maximum heating rate is limited by the possibility to infer the microstructural state from the calorimetric results. The substantial quality of the measured descriptors for micro samples has to be quantified and analyzed depending on the heating rate. In this work, the first results of the measurements of calorimetric descriptors with increased heating rates for 100Cr6 will be presented and discussed. The results of low and high heating rates will be compared and analyzed using additional microhardness measurements. Furthermore, the validation of the method regarding the suitability for the evolutionary material development includes up-scaling to macro level and therefore different sample masses will be investigated using micro and macro samples during calorimetry.

Abstract:
Calorimetry is an avenue for exploring the energy change due to heat involved between the various reaction stages at chemical, physical, or phase transition levels. Calorimetry seeks to determine the calories contained in food items within food science. However, classical calorimetric analyses are time-consuming and require a good amount of human intervention. The concept of image processing, involving the YOLO object detection algorithm, along with IoT technologies are a completely new domain in automating calorimetric measurements in food with high accuracy. YOLO's fast and efficient detection of the object allows accurate identification and tracking of food samples during the analysis. The project aims to develop a system that will efficiently and accurately measure the caloric value of carbonized food samples using image processing using YOLO and IoT-unified data collection method to automate the whole data gathering process and achieve precision in measurement and with monitoring and analysis in real time.

Abstract:
The article considers the current methods of measuring the calorific value of natural gas which are valid in the upto-date gasometry. The procedure for measuring the gross and net volume-basis specific calorific value of natural gas by the calorimetric method is analyzed. It is shown that to increase the accuracy and validity of measurement results, the experiment to determine the values of gross and net volume-basis specific calorific should be performed for at least 5 samples of the investigated gas. A methodology for estimating the accuracy of measuring the gross and net volume-basis specific calorific values of natural gas by the calorimetric method by finding estimates of the uncertainty of the obtained measurement results taking into account both random and systematic influencing factors are developed. The uncertainty budgets for measuring the gross and net volumebasis-specific calorific values of natural gas have been developed for the practical implementation of the methodology. The results of experimental studies of samples of one of the natural gas fields are given and the objective values of the gross and net volumebasis specific calorific with estimates of extended uncertainty are obtained.

Abstract:
This work connects the calorimetric responses of different rubber–resin blends with varying resin contents with their alpha relaxation dynamics. We used differential scanning calorimetry and broadband dielectric spectroscopy to characterize the calorimetric and dielectric responses of styrene–butadiene, polybutadiene, and polyisoprene with different resin contents. To model the results, we used the Gordon–Taylor equation combined with an extension of the Adam–Gibbs approach. Thus, we propose a simple and effective model that allows us to estimate the blend dynamics from the temperature dependence of the relaxation times of the pure components and the calorimetric measurement of the glass transition temperature of only one blend composition. By estimating an effective interaction parameter from calorimetry, we achieved accurate alpha relaxation dynamics predictions for different resin concentrations. Our highly predictive approach provides a realistic description of the expected dynamics. This study offers valuable insights into the dynamic properties of polymer compounds, paving the way for the fast and effective development of advanced and more sustainable materials.

Abstract:
The standard enthalpy of formation of InN at 298 K has been determined using high-temperature oxidative drop solution calorimetry in a molten sodium molybdate solvent at 975 K. Calorimetric measurements were performed on six InN samples with varying nitrogen contents. The samples were characterized using x-ray diffraction, chemical analysis, electron microprobe analysis, and Brunauer–Emmett–Teller surface area measurement. The variation of the enthalpy of drop solution (kJ/g) with nitrogen content is approximately linear. The data, when extrapolated to stoichiometric InN, yield a standard enthalpy of formation from the elements of ?28.6 ± 9.2 kJ/mol. The relatively large error results from the deviation of individual points from the straight line rather than uncertainties in each set of data for a given sample. This new directly measured enthalpy of formation is in good agreement with the old combustion calorimetric result by Hahn and Juza (1940). However, this calorimetric enthalpy of formation is significantly different from the enthalpy of formation values derived from the temperature dependence of the apparent decomposition pressure of nitrogen over InN. A literature survey of the enthalpies of formation of III–N nitride compounds is presented.

Abstract:
AbstractMeasurement of energy expenditure in humans is required to assess metabolic needs, fuel utilisation, and the relative thermic effect of different food, drink, drug and emotional components. Indirect and direct calorimetric and non-calorimetric methods for measuring energy expenditure are reviewed, and their relative value for measurement in the laboratory and field settings is assessed. Where high accuracy is required and sufficient resources are available, an open-circuit indirect calorimeter can be used. Open-circuit indirect calorimeters can employ a mask, hood, canopy or room/chamber for collection of expired air. For short-term measurements, mask, hood or canopy systems suffice. Chamber-based systems are more accurate for the long-term measurement of specified activity patterns but behaviour constraints mean they do not reflect real life. Where resources are limited and/or optimum precision can be sacrificed, flexible total collection systems and non-calorimetric methods are potentially useful if the limitations of these methods are appreciated. The use of the stable isotope technique, doubly labelled water, enables total daily energy expenditure to be measured accurately in free-living subjects. The factorial method for combining activity logs and data on the energy costs of activities can also provide detailed information on free-living subjects.

Abstract:
With regard to the problem of refining the fundamental equations of state of hydrocarbons, the methodological and design features of the experimental measurement of the isobaric heat capacity in the critical region by the method of a flow adiabatic calorimeter are considered. The pressure measurement system has been improved by introducing a differential manometer into the measuring circuit, which made it possible not only to increase the accuracy of pressure determination, but also to implement a universal scheme of calorimetric experiment. The use of a universal scheme of the calorimetric experiment allows one to determine two values of the isobaric heat capacity at pressures that differ by the value of the pressure loss in the calorimeter. Such an approach in the critical region is relevant, since it makes it possible to quite simply and reliably determine the value of the derivative of the heat capacity with respect to pressure, which is used to estimate not only the error in assigning the value of heat capacity to pressure, but also the equilibrium conditions of the experiment in a flow-through calorimeter. The technique of determining and making a correction for the inhomogeneity of the supply wires of the differential thermocouple, for the throttling of the flow of matter in the calorimeter is considered. Correct relations are obtained for determining the average temperature of the measurement experiment for various methods of measuring the temperature and temperature difference in a flow-through calorimeter. The results of experimental measurements of the isobaric heat capacity of n-pentane in the critical region, obtained using the universal scheme of the calorimetric experiment, for n-pentane were measured on an isobar of 3.400 MPa (critical pressure 3.355 MPa), which is the closest to the critical point at practice of flow calorimetry

Abstract:
MINOS is a long-baseline neutrino oscillation experiment. A neutrino beam is created at the Fermi National Accelerator Laboratory in Illinois and fired down through the Earth. Measurements of the energy spectra and composition of the neutrino beam are made both at the source using the Near detector and 735 km away at the Soudan Underground Laboratory in Minnesota using the Far detector. By comparing the spectrum and flavour composition of the neutrino beam between the two detectors neutrino oscillations can be observed. Such a comparison depends on the accuracy of the relative calorimetric energy scale. This thesis details a precise measurement of the calorimetric energy scale of the MINOS Far detector and Calibration detector using stopping muons with a new "track window" technique. These measurements are used to perform the relative calibration between the two detectors. This calibration has been accomplished to 1.7% in data and to significantly better than 2% in the Monte Carlo simulation, thus achieving the MINOS relative calibration target of 2%. A number of cross-checks have been performed to ensure the robustness of the calorimetric energy scale measurements. At the Calibration detector the test-beam energy between run periods is found to be consistent with the detector response to better than 2% after the relative calibration is applied. The muon energy loss in the MINOS detectors determined from Bethe-Bloch predictions, data and Monte Carlo are compared and understood. To estimate the systematic error on the measurement of the neutrino oscillation parameters caused by a relative miscalibration a study is performed. A 2% relative miscalibration is shown to cause a 0.6% bias in the values of Δm<sup>2</sup> and sin<sup>2</sup>(2θ).

Abstract:
The oscillation experiments have clearly shown that neutrino are massive particle. Nowadays the experiments based on kinematic analysis of electrons emitted in nuclear beta-decay are the most sensitive for a direct electron-neutrino mass determination. The method consists in searching for a tiny deformation caused by a non-zero neutrino mass to the spectrum of the charged particles emitted near the end point. A possible approach is the calorimetric one. In a calorimetric measurement the source is embedded in the detector and all the energy is measured, except for the one taken away by the neutrino. A drawback of this approach is that the full spectrum is acquired, while only the decays very close to the end-point are useful for measuring the neutrino mass. Therefore, the source activity has to be limited to avoid pile-up which would deform the shape of beta spectrum. As a consequence the statistics near the end-point is limited as well. This limitation may be then partially balanced by using isotopes with an end-point energy as low as possible. In this scenario an international collaboration has grown around the project of Microcalorimeter Arrays for a Rhenium Experiment (MARE) for a direct calorimetric measurement of the neutrino mass with sub-electronvolt sensitivity. Although the baseline of the MARE project consists in a large array of rhenium based thermal detectors, a different option for the isotope is also being considered. The two competing isotopes are 187Re and 163Ho. While the first beta decays, the latter decays via electron capture, and both have a Q value around 2.5 keV. The MARE project has a staged approach. The first phase of the project (MARE-1) is a collection of activities with the aim of sorting out both the best isotope and the most suited detector technology to be used for the final experiment. The goal of the last phase (MARE-2) is to achieve a sub-eV sensitivity on the neutrino mass. It will deploy several arrays of thermal microcalorimeters. During my Ph.D I have focused only on the rhenium isotope, neglecting the holmium. In fact, in the case of rhenium I have estimated the statistical sensitivity of a neutrino mass experiment performed with thermal calorimeters. First, through an analytical approach, I have derived an algorithm to assess the statistical sensitivity for a given experimental configuration and then, for the same experimental configuration, I have estimated the sensitivity on neutrino mass via a Montecarlo method. The results of the analytic approach are then validated through the comparison with the Montecarlo results over a wide range of experimental parameters. The investigation is carried out for both phases of the MARE experiment. For example, the Montecarlo approach has shown that a neutrino mass sensitivity of 0.1 eV at 90% CL could be expected in 10 years running 3x10^5 detectors, each with a mass of 10 mg (~10 Hz) and with energy and time resolutions of about 1 eV and 1 μs respectively. Instead, a sensitivity on neutrino mass of 3.4 eV at 90% CL could be achieved in 3 years using 288 detectors, each with a mass of 500 μg (~ 0.3 Hz) and with energy and time resolutions of about 30 eV and 300 μs respectively. The latter is the configuration of the Milano MARE-1 experiment, which is one of the MARE-1 activities. Subsequently, I have exploited the Montecarlo approach to study the main sources of systematic uncertainties of the calorimetric experiments, as the shape of the beta spectrum and the Beta Environmental Fine Structure (BEFS), which is a modulation of the beta spectrum due to the atoms surrounding the decaying nuclei. The systematics uncertainties relating to the source (i.e. excited final states and the escape electron) have been also investigated. Finally, I have evaluated the capability of the MARE experiment to measure the mass of heavy neutrinos from some tens of eV to 2.5 keV. I have also participated in the Milano MARE-1 experiment. This experiment is carried out in Milano by the group of Milano--Bicocca in collaboration with NASA/GSFC and Wisconsin groups. The Milano MARE-1 arrays are based on semiconductor thermistors, provided by the NASA/GSFC group, with dielectric silver perrhenate absorbers, AgReO4. These arrays consist of 6 x 6 implanted Si:P thermistors on which single crystal of AgReO4 are attached. The mass of a single absorber is around 500 μg, corresponding to a single detector rate of 0.3 Hz. The cryogenic set-up of MARE-1 is designed to host up to 8 arrays (i.e. 288 detectors), but the installation of only two arrays has been funded so far. The read-out electronics of MARE-1 in Milano is characterized by a cold buffer stage, based on JFETs which work at about 120 K, followed by an amplifier stage at room temperature. To electrically connect the detector at 85 mK to the JFETs at 120 K two decoupling stages are needed. The two stages have also to guarantee the mechanical stability. The first stage separates the detectors from the JFETs box, while the second one decouples the cold electronics box from the JFETs. In this context, the activities I have carried out were focused primarily on the assembly of the entire cryogenic set-up of MARE-1 in Milano and then on its analysis and improvement. Firstly, I have performed several cool-downs devoted to test the detector performances and to determinate the best thermal coupling between Si thermistors and AgReO4 absorbers, in conclusion of which we have obtained an energy resolution of around 30 eV at 2.6 keV and a rise time of about 300 μs. With 72 detectors and such performances, a sensitivity on neutrino mass of 4.7 eV at 90% C.L. is expected in three years running time. During these cool-downs it was used the electronics of the MIBETA experiment, the predecessor of the MARE-1 experiment in Milano. Since its first installation the cryogenic set-up of MARE-1 has presented several structural and thermal problems. The first has concerned the electrical connections between the detectors and electronics, while the latter the insufficient thermal decoupling between the JFETs support and the cold electronic box as well as the insufficient thermalization of the array ceramic board and of the array itself. As a consequence, no signal could be acquired. Therefore, I have performed an R&D work in order to solve all of these problems in conclusion of which the detectors have reached a base temperature such that it was possible to acquire a first spectrum with a threshold below 800 eV. In this condition, an energy resolution of 175 eV at 1.5 keV and of 181 eV at 5.9 keV have been obtained, while the rise time was about 850 μs. It was the first time that a spectrum with this threshold was acquired with the MARE-1 set-up. The worsening observed in the detectors performances with respect to the test runs was due to an excessive microphonics noise. Nevertheless it can be hypothesized that a 72 channels measurement will be starting soon.

Abstract:
This thesis explores experimentally and theoretically two different aspects of the properties and behaviour of metals: their ability to damp noise and their susceptibility to crack when solidifying. The first part concerns intrinsic material damping, and is motivated by increased demands from society for reductions in noise emissions. It is a material’s inherent ability to reduce its vibration level, and hence noise emission, and transform its kinetic energy into a temperature increase. To design new materials with increased intrinsic material damping, we need to be able to measure it. In this thesis, different methods for measurement of the intrinsic damping have been considered: one using Fourier analysis has been experimentally evaluated, and another using a specimen in uniaxial tension to measure the phase-lag between stress and strain has been improved. Finally, after discarding these methods, a new method has been developed. The new method measures the damping properties during compression using differential calorimetry. A specimen is subjected to a cyclic uniaxial stress to give a prescribed energy input. The difference in temperature between a specimen under stress and a non-stressed reference sample is measured. The experiments are performed in an insulated vacuum container to reduce convective losses. The rate of temperature change, together with the energy input, is used as a measure of the intrinsic material damping in the specimen. The results show a difference in intrinsic material damping, and the way in which it is influenced by the internal structure is discussed. The second part of the thesis examines hot cracks in solidifying shells. Most metals have a brittle region starting in the two-phase temperature range during solidification and for some alloys this region extends as far as hundreds of degrees below the solidus temperature. To calculate the risk of hot cracking, one needs, besides knowledge of the solidifying material’s ability to withstand stress, knowledge of the casting process to be able to calculate the thermal history of the solidification, and from this calculate the stress. In this work, experimental methods to measure and evaluate the energy transfer from the solidifying melt have been developed. The evaluated data has been used as a boundary condition to numerically calculate the solidification process and the evolving stress in the solidifying shell. A solidification model has been implemented using a fixed-domain methodology in a commercial finite element code, Comsol Multiphysics. A new solidification model using an arbitrary Lagrange Eulerian (ALE) formulation has also been implemented to solve the solidification problem for pure metals. This new model explicitly tracks the movement of the liquid/solid interface and is much more effective than the first model.<br>QC 20100929

The certified thesis is available in the Institute Archives and Special Collections.<br>Includes bibliographical references (p. 135-139).<br>Due to the finite supply of oil, energy availability and price are issues facing the world. Among the possible approaches to this problem is research of new physical effects which may produce energy in novel ways. The Yang-Koldamasov device was reported to produce excess heat by iESi by pumping oil through a thin nozzle; however, the theoretical mechanism for this effect is at the present unknown. The subject of this thesis is an attempt at independent confirmation of the effect at MIT and FRC. To perform calorimetry on this device, there are several issues involved, such as thermocouple offset errors, RF noise, and erroneous readings due to fluid flow conditions. Methods for handling these issues are discussed in application to two independent measurements of energy gain in the system, differential calorimetry over the cell, and flow calorimetry via a heat exchanger. The differential calorimetry has been improved compared to what was earlier available on Yang-Koldamasov devices, and the flow calorimetry is new to the device. Data was collected on several tests After analysis, the data was found consistent with a null result. However, over the course of the runs the behavior of the device was very different than the behavior at earlier demonstrations where excess heat was observed. For example, earlier demonstrations exhibited electrical arcing perpendicular to the flow of oil, while the current device shows only arcing in the direction of oil flow. Future work is being conducted by FRC to identify the reasons that the current apparatus behaves differently.<br>by Jennifer Novosad.<br>M.Eng.

Abstract:
La mesure précise de la masse du boson W est une composante essentielle pour tester la cohérence globale du Modèle Standard, dont une défaillance pourrait mettre à jour la nouvelle physique. Avec des millions de bosons W prévus, les futures expériences seront des usines à bosons permettant de mesurer sa masse avec une précision inégalée. La mesure de la masse du W est discutée dans le contexte de deux expériences : l'amélioration du détecteur CMS au LHC, le HL-LHC, avec un nouveau bouchon calorimétrique, le HGCal, et à un détecteur pour FCC-ee, un projet circulaire post-LHC. En collision proton-proton, la mesure précise de la masse du boson W dépend de la précision de la mesure du recul hadronique. Cette précision dépend principalement de la définition du recul et des effets induits par le détecteur. La définition du recul est améliorée par des méthodes de machine learning, en utilisant une régression quantile multivariée. Les effets de la granularité, de l'acceptance et de la résolution du HGCal sur le recul sont évalués. Cette étude donne une estimation de la précision sur la masse du boson W qui pourrait être atteinte au HL-LHC. Avant d'estimer les effets de la performance du détecteur sur le recul, la géométrie complète et les paramètres du détecteur ont été ajustés et optimisés. Un fidèle outil de simulation rapide, complément au logiciel de simulation complet de CMS, implémenté pour mener cette étude, est présenté. En collision électron-positron, la masse du boson W peut être déterminée à partir du produit de désintégration de la paire de W. Les incertitudes statistiques sur la masse et la largeur sont estimées en utilisant la méthode du fit cinématique, dans les canaux de désintégration hadronique et semi-leptonique à 162,6 GeV, 240 GeV et 365 GeV. Atteignant une incertitude statistique inférieure au niveau du MeV/c² à toutes les énergies et pour les deux canaux, la mesure de la masse du W devient limitée par les incertitudes systématiques. Un traitement pour réduire l'incertitude systématique engendrée par les effets QCD, la plus large source d'incertitude systématique à LEP, et son impact sur l'incertitude statistique sont également étudiées<br>The precise measure of the W boson mass is an essential input to a crucial test of the overall consistency of the Standard Model, whose failure might reveal the emergence of new physics. With millions of W bosons expected, future experiments will be W boson factories allowing the measurement of the W mass with unparalleled precision. The W mass measurement is discussed in the context of two experiments: the upgrade of CMS at the LHC, the HL-LHC, with a new endcap calorimeter, the HGCal, and a detector for the FCC-ee, a circular post-LHC project. In proton-proton collisions, the precise measurement of the W mass relies on a precise measurement of the hadronic recoil. Its accurate measurement mainly depends on its definition model and detector effects. The recoil definition is improved with machine learning techniques, using a multivariate quantile regression. The effects of the HGCal granularity, acceptance and resolution on the recoil reconstruction are evaluated. This study gives an estimate of the precision that might be reached on the W mass measurement at HL-LHC. Before evaluating the effect of the detector performance on the recoil, the full geometry and parameters had to be tuned and optimised. An accurate fast simulation tool, complement to the full CMS simulation, implemented to undertake such a study, is presented. In electron-positron collisions, the W mass can be determined from the W-pair decay products. The statistical uncertainties on the W mass and width are estimated using a kinematic fit technique in the hadronic and semi-leptonic channels at 162.6 GeV, 240 GeV and 365 GeV. Reaching a statistical precision below the MeV/c² level at all energies for both channels, the W mass measurement becomes limited by the systematic uncertainties. A treatment to reduce the systematic uncertainty coming from QCD effects, the largest source of systematic uncertainty at LEP, and its impact on the statistical uncertainty are also studied

Abstract:
AbstractThis chapter describes the various physical principles associated with the calorimetric assay method for determining the mass of radionuclides within an item based on a combination of a thermal power measurement and knowledge of the isotopic composition of the item. The principles that are discussed within this chapter include the method for performing a calorimetric assay method, the production of heat from nuclear materials, the determination of specific thermal power for a given item containing radionuclides, and descriptions of the types of heat-flow calorimeters that have been used to perform measurements on nuclear material bearing items.

Full text
Abstract:
This document describes a test method for the degree of reaction of fusion-bonded epoxy coatings by direct-current resistivity. This method covers the determination of a transition temperature of cured fusion-bonded epoxy coatings by measurement of the changes in direct-current resistivity of the coating with temperature. Comparison of this temperature with the degree of reaction for that coating material as determined by differential scanning calorimetry will allow the estimation of the degree of reaction of the coating sample being tested.
