Resumen

It is devoted to the problem of spreading errors in the information of the State Land Cadastre, the reasons for their occurrence and the procedure for editing errors. The main types of errors in the information of the State Land Cadastre, the reasons for their spread, ways to solve. The algorithm of actions at detection of such errors by the interested persons (legal or physical) and the state cadastral registrar is considered. The article reflects the powers of the state cadastral registrar in correcting various types of errors. The main types of errors in the information of the State Land Cadastre are: technical errors that arose due to / not through the fault of the body conducting the DZK; errors caused by existing errors in other documents. The interested person who found an error in the information of the State Land Cadastre should apply to the body conducting the State Land Registry with a notice, which must comply with a certain annex to the Procedure for maintaining the State Land Cadastre (depending on the type of error). The state cadastral registrar corrects the detected errors on the basis of the application, the document in which there is an error and the document establishing the right to land. He must then provide an extract or certificate certifying that the error found has been corrected.

Resumen

The positioning accuracy is a key index to measure the performance of the robot. This paper studies the positioning accuracy of the main pouring mechanism of the hybrid truss pouring robot and analyzes that the main error sources affecting the positioning accuracy are machining error, assembly error, and thermal deformation error. Error transfer matrix is constructed to describe the influence of machining errors and assembly errors on the position and pose of the terminal, and the error parameters have physical significance. The probability distribution of sensitive errors is discussed. A joint regression prediction model based on sensitive error sets is established to determine the thermal deformation error on the basis of fully considering the contribution rate of component error. The results show that the position error has a wide range of influences on the end pose, but the angle error is more sensitive, and the probability distribution of the sensitive error is concentrated. The reliable data can be obtained without reorganizing the measurement in the calibration process. The joint regression model considering the contribution rate of component error can effectively eliminate the collinearity problem in the prediction of thermal deformation from a single heat source. Compared with the single regression model, it has better prediction accuracy and effect.

Resumen

Abstract. Lidars have become a valuable technology to assess the wind resource at hub height of modern wind turbines. However, because of the assumption of homogeneous flow in their wind vector reconstruction algorithms, common wind profile Doppler lidars suffer from errors at complex terrain sites. This study analyses the impact of the five main influencing factors for lidar measurement errors in complex terrain, i.e. orographic complexity, measurement height, surface roughness and forest, atmospheric stability, and half-cone opening angle, in a non-dimensional, model-based parameter study. In a novel approach, the lidar error ε is split up into a part εc, caused by flow curvature at the measurement points of the lidar, and a part εs, caused by the local speed-up effects between the measurement points. This approach allows for a systematic and complete interpretation of the influence of the half-cone opening angle φ of the lidar on the total lidar error ε. It also provides information about the uncertainty in simple lidar error estimations that are based on inflow and outflow angles at the measurement points. The model-based parameter study is limited to two-dimensional Gaussian hills with hill height H and hill half-width L. H/L and z/L, with z being the measurement height, are identified as the main scaling factors for the lidar error. Three flow models of different complexity are used to estimate the lidar errors. The outcome of the study provides various findings that enable an assessment of the applicability of these flow models. The study clearly shows that orographic complexity, roughness and forest characteristics, and atmospheric stability have a significant influence on lidar error estimation. Based on the error separation approach it furthermore allows for an in-depth analysis of the influence of reduced half-cone opening angles, explaining contradiction in the previously available literature. The choice and parameterization of flow models and the design of methods for lidar error estimation are found to be essential to achieve accurate results. The use of a Reynolds-averaged Navier–Stokes (RANS) computational fluid dynamics (CFD) model in conjunction with an appropriate forest model is highly recommended for lidar error estimations in complex terrain since forest (and roughness) tends to reduce the lidar error. If atmospheric stability variation at a measurement site plays a vital role, it should also be considered in the modelling. When planning a measurement campaign, an accurate estimation of the predicted lidar error should be carried out in advance to choose a reasonable measurement location. This will decrease measurement uncertainties and maximize the value of the measurement data.

Resumen

As a key indicator reflecting the working accuracy of rotary functional units, the error motions of the precision shafting are very necessary to be measured. In this paper, the main error sources for the error motion measurement of a precision shafting using a T-type capacitive sensor were investigated. The theoretical modeling error due to the approximate simplification for the output capacitance expressions was firstly analyzed. By means of the 3D-FEA method, the influence of fringe effects was subsequently investigated. Finally, the analysis of electrode installation errors was emphasized on the tilt error of the cylindrical electrode and coaxiality error of the fan-shaped electrode by establishing mathematical models and numerical simulation. Based on the theoretical analysis and simulation results, the methods of decreasing the approximate error and the nonlinear error caused by fringe effects were subsequently proposed; for the installation errors, the tilt error of cylindrical electrode only makes the solution of phase angle have a certain deviation and has almost no effect on solving the radial displacement, especially for the measurement range less than 0.1 mm; the measurement of the rotor tilt displacement was basically not affected by the coaxiality error of the fan-shaped electrode.

Resumen

Diagnostic errors in medicine occur frequently and the consequences for the patient can be severe. Cognitive errors as well as system related errors contribute to the occurrence of diagnostic error, but it is generally accepted that cognitive errors are the main contributor. The diagnostic reasoning process in medicine, is an understudied area of research. One reason is because of the complexity of the diagnostic process and therefore the difficulty to measure diagnostic errors and the causes of diagnostic error. In this paper, I discuss some of the complexities of the diagnostic process. I describe the dual-process theory, which defines two reasoning modes, 1. a fast, automatic and unconscious reasoning mode called system 1, and a slow and analytic reasoning mode called system 2. Furthermore, the main cognitive causes of diagnostic error are described.

Resumen

Multiple factors determine the reliability in the engine repair, while an important criterion is the preservation of the geometric parameters of engine parts within the specifi ed limits. The crankshaft bearing is a highly loaded unit in an engine. If the holes for the main bearing shells are worn or deformed, the shells may rotate, which will lead to failure and unscheduled repairs. The authors found out that measuring instruments typically recommended in the normative and technical documentation are assigned without regard to the tolerances of controlled quantities and have an error that signifi cantly exceeds the permissible measurement error. The purpose of the work is to study the degree of infl uence of the measurement error on the dispersion zone of the dimensions of the mainbearing journals of the engine during fault detection. The authors have theoretically proven the criteria for choosing measuring instruments for monitoring holes for main bearing shells. The limit values of the permissible measurement errors and the errors of measuring instruments for monitoring wear or deformation of the holes for the liners of main bearings that are submitted for fault detection were also determined. The paper also considers the infl uence of the measurement error on the probability of errors when making a decision on the suitability of parts. When comparing the measuring instruments recommended for use by the engine repair manual, the number of incorrectly rejected parts is 6.9% more, and the number of incorrectly accepted parts is 3.5% more than when using a more accurate bore gauge with an error of ±3.5 microns. Reducing the error of measuring instruments will lead to a signifi cant reduction in the number of incorrectly accepted and incorrectly rejected parts. This, in turn, will aff ect both the quality of the subsequent assembly of units, and the amount of external losses resulting from faulty parts.

Resumen

Trabalho apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Ciências Farmacêuticas.
Os erros inatos do metabolismo referem-se a um grupo de doenças geneticamente determinadas, decorrentes da deficiência numa via metabólica envolvida na síntese, no transporte ou na degradação de uma substância. O aspecto clínico que cada uma destas doenças pode tomar resulta da acumulação do substrato de uma reacção, da falta de produto dessa mesma reacção ou da acumulação de uma substância originada a partir de uma via metabólica alternativa. Estes erros, apesar de isolados apresentarem uma pequena incidência sobre a população, quando descritos em conjunto (cerca de quinhentos conhecidos), tornam-se mais comuns, apresentando taxas de incidência na ordem de 1 caso a cada 1000 nascimentos. Sabe-se hoje que a rápida detecção destas doenças é que determina a gravidade que estas podem assumir, pelo que os programas de triagem neonatal estão em constante evolução no que respeita ao aperfeiçoamento das técnicas de diagnóstico, para que os resultados dos tratamentos sejam cada vez mais expressivos. Este trabalho aborda inicialmente os erros inatos do metabolismo de uma forma genérica, dando depois lugar à análise das três desordens metabólicas mais frequentes em Portugal: a deficiência na enzima acil-CoA desidrogenase de cadeia média, a fenilcetonúria e a deficiência na enzima 3-metilcrotonil carboxilase. São descritas para as três as deficiências que ocorrem nas vias metabólicas que essas enzimas catalisam, os aspectos clínicos da doença que originam, as suas formas de detecção e as estratégias terapêuticas que estão actualmente disponíveis. Inborn errors of metabolism refer to a group of genetically determined diseases, resulting from a deficiency in a metabolic pathway involved in the synthesis, transport or degradation of a substance. The clinical aspect that each of these diseases can take results from the accumulation of the substrate reaction, the lack of product of the same reaction, or the accumulation of a substance originated from an alternative metabolic pathway. These errors, although isolates showed a small impact on the population, when described together (about five hundred known), become more common, with incidence rates in the order of 1 case per 1000 births. It is now known that early detection of these diseases, determines the severity of the disease can take, so the neonatal screening programs are constantly evolving in relation to improved diagnostic techniques, to treatment outcomes are increasingly more expressive. This work first discusses the inborn errors of metabolism in a generic way and then gives way to analysis of the three most common metabolic disorders in Portugal: the deficiency in the enzime medium chain acyl-CoA dehydrogenase, phenylketonuria and deficiency in the enzyme 3-methylcrotonyl carboxylase. For the three are described the deficiencies that occurs in metabolic pathways that these enzymes catalyze, the clinical aspects of disease that originate, their forms of detection and the therapeutic strategies that are currently available.

AbstractLearning with error was proposed by O. Regev in 2005 (see Regev, 2009), which can be regarded as a dual form of SIS problem. LWE has very important applications in modern cryptography, such as LWE-based fully homomorphic encryption. The main purpose of this chapter is to explain the mathematical principles of the LWE problem in detail, especially the polynomial equivalence between the average LWE problem and the hard problems on lattice, which is one generalization of the Ajtai reduction principle and solves the computational complexity of the LWE problem effectively.

Resumen

AbstractReliability of the memory subsystem is a growing concern in computer architecture and system design. From on-chip embedded memories in Internet-of-Things (IoT) devices and on-chip caches to off-chip main memories, the memory subsystems have become the limiting factor in the overall reliability of computing systems. This is because they are primarily designed to maximize bit storage density; this makes memories particularly sensitive to manufacturing process variation, environmental operating conditions, and aging-induced wearout. This chapter of the book focuses on software managed techniques and novel error correction codes to opportunistically cope with memory errors whenever they occur for improved reliability at minimal cost.

Resumen

AbstractDue to the consistent pressing quest of larger on-chip memories and caches of multicore and manycore architectures, Spin Transfer Torque Magnetic RAM (STT-MRAM or STT-RAM) has been proposed as a promising technology to replace classical SRAMs in near-future devices. Main advantages of STT-RAMs are a considerably higher transistor density and a negligible leakage power compared with SRAM technology. However, the drawback of this technology is the high probability of errors occurring especially in write operations. Such errors are asymmetric and transition-dependent, where 0 → 1 is the most critical one, and is high subjected to the amount and current (voltage) supplied to the memory during the write operation. As a consequence, STT-RAMs present an intrinsic trade-off between energy consumption vs. reliability that needs to be properly tuned w.r.t. the currently running application and its reliability requirement. This chapter proposes FlexRel, an energy-aware reliability improvement architectural scheme for STT-RAM cache memories. FlexRel considers a memory architecture provided with Error Correction Codes (ECCs) and a custom current regulator for the various cache ways and conducts a trade-off between reliability and energy consumption. FlexRel cache controller dynamically profiles the number of 0 → 1 transitions of each individual bit write operation in a cache block and based on that selects the most-suitable cache way and current level to guarantee the necessary error rate threshold (in terms of occurred write errors) while minimizing the energy consumption. We experimentally evaluated the efficiency of FlexRel against the most efficient uniform protection scheme from reliability, energy, area, and performance perspectives. Experimental simulations performed by using gem5 has demonstrated that while FlexRel satisfies the given error rate threshold, it delivers up to 13.2% energy saving. From the area footprint perspective, FlexRel delivers up to 7.9% cache ways’ area saving. Furthermore, the performance overhead of the FlexRel algorithm which changes the traffic patterns of the cache ways during the executions is 1.7%, on average.

Resumen

AbstractLaboratory medicine in the healthcare system has recently been recognized as a fundamental service in the clinical decision-making process. Therefore, the notion of patient safety in laboratory medicine must be recognized as the assurance that harm to patients will be avoided, safe care outcomes will be enhanced through error prevention, and the total testing process (TTP) will be continuously improved.Although the goal for patient safety is zero errors, and although laboratory professionals have made numerous efforts to reduce errors in the last few decades, current research into laboratory-related diagnostic errors highlights that: (a) errors occur at every step of the TTP, mainly affecting phases at clinical interfaces; (b) despite the improvement strategies adopted, analytical quality remains a challenge; (c) errors are linked not only to clinical chemistry tests, but also to new, increasingly complex diagnostic testing.Medical laboratories must therefore implement effective quality assurance tools to identify and prevent errors in order to guarantee the reliability of laboratory information. Accreditation in compliance with the International Standard ISO 15189 represents the first step, establishing processes with excellence requirements and greater expectations of staff competency. Another important step in preventing errors and ensuring patient safety is the development of specific educational and training programs addressed to all professionals involved in the process, in which both technical and administrative skills are integrated. A wide variety of information is provided by a robust quality management system and consensus-approved Quality Indicators (QI) that identify undesirable events, evaluate the risk to the patient, and call for corrective and preventive actions. However, the effectiveness of the system depends on the careful analysis of data collected and on staff awareness of the importance of laboratory medicine to the healthcare process. The main task of the new generation of laboratory professionals should be to gain experience in “clinical laboratory stewardship.” In order to safeguard patients, laboratory professionals must assist clinicians in selecting the right test for the right patient at the right time and facilitate the interpretation of laboratory information.

Resumen

AbstractThis chapter is the core theoretical chapter on predictive modeling, forecast evaluation and model selection. The main problem in actuarial modeling is to forecast and price future claims. For this, we build predictive models, and this chapter deals with assessing and ranking these predictive models. We therefore introduce the mean squared error of prediction (MSEP) and, more generally, the expected generalization loss (GL) to assess predictive models. This chapter is complemented by a more decision-theoretic approach to forecast evaluation, it discusses deviance losses, proper scoring, elicitability, forecast dominance, cross-validation, Akaike’s information criterion (AIC) and we give an introduction to the bootstrap simulation method.

Resumen

AbstractWe consider inverse parametric problems for elliptic variational PDEs. They are solved through the minimization of misfit functionals. Main difficulties encountered consist in the misfit multimodality and insensitivity as well as in the weak conditioning of the direct (forward) problem, that therefore requires stabilization. A complex multi-population memetic strategy hp-HMS combined with the Petrov-Galerkin method stabilized by the Demkowicz operator is proposed to overcome obstacles mentioned above. This paper delivers the theoretical motivation for the common inverse/forward error scaling, that can reduce significantly the computational cost of the whole strategy. A short illustrative numerical example is attached at the end of the paper.

Resumen

Digitalized nuclear instruments and control systems have become the main stream design for the main control room (MCR) of advanced nuclear power plants (NPPs) nowadays. Digital human-system interface (HSI) could improve human performance and, on the other hand, could reduce operators’ situation awareness as well. It might cause humans making wrong decision during an emergency unintentionally. Besides, digital HSI relies on computers to integrate system information automatically instead of human operation. It has changed the operator’s role from mainly relating operational activity to mainly relating monitoring. However, if operators omit or misjudge the information on the video display units or wide display panel, the error of omission and error of commission may occur. Therefore, how to avoid and prevent human errors has become a very imperative and important issue in the nuclear safety field. This study applies Performance Evaluation Matrix to explore the potential human errors problems of the MCR. The results show that the potential problems which would probably affect to the human performance of the MCR in advanced NPPs are multiple accidents, pressure level, number of operators, and other factors such as working environmental.

Texto completo

Resumen

The purpose of this paper is to introduce the concept of drop unit substitution in address-based samples for mail and web surveys. A drop point is a single US Postal Service (USPS) delivery point or receptacle that services multiple businesses, families, or households (USPS, 2017). Residential drop units are the individual housing units served by the drop point address. For the most part, address-based sampling frames list the number of units at a drop point address but will not contain information identifying specific units. Drop units comprise less than 2 percent of all residential addresses in the United States (McMichael, 2017), but they tend to be concentrated in certain large cities. In Queens, New York, for example, drop units constitute 27 percent of residential housing units. The problem with drop units for address-based surveys with mail contacts is that, without names or unit identifiers, there is no way to control which unit receives the various mailings. This limitation leads to distorted selection probabilities, renders the use of cash incentives by mail impractical, and precludes traditional methods for mail nonresponse follow-up, thus resulting in higher nonresponse. Alternatively, excluding drop units results in coverage error, which can be considerable for some subnational estimates. The authors propose a substitution approach when a drop unit is sampled—in other words, replacing the unit with a similar nearby unit in a non–drop point building.

Resumen

This project includes two main parts: Development of a “Selective Wavelength Imaging Sensor” and an “Adaptive Classifiery System” for adaptive imaging and sorting of agricultural products respectively. Three different technologies were investigated for building a selectable wavelength imaging sensor: diffraction gratings, tunable filters and linear variable filters. Each technology was analyzed and evaluated as the basis for implementing the adaptive sensor. Acousto optic tunable filters were found to be most suitable for the selective wavelength imaging sensor. Consequently, a selectable wavelength imaging sensor was constructed and tested using the selected technology. The sensor was tested and algorithms for multispectral image acquisition were developed. A high speed inspection system for fresh-market carrots was built and tested. It was shown that a combination of efficient parallel processing of a DSP and a PC based host CPU in conjunction with a hierarchical classification system, yielded an inspection system capable of handling 2 carrots per second with a classification accuracy of more than 90%. The adaptive sorting technique was extensively investigated and conclusively demonstrated to reduce misclassification rates in comparison to conventional non-adaptive sorting. The adaptive classifier algorithm was modeled and reduced to a series of modules that can be added to any existing produce sorting machine. A simulation of the entire process was created in Matlab using a graphical user interface technique to promote the accessibility of the difficult theoretical subjects. Typical Grade classifiers based on k-Nearest Neighbor techniques and linear discriminants were implemented. The sample histogram, estimating the cumulative distribution function (CDF), was chosen as a characterizing feature of prototype populations, whereby the Kolmogorov-Smirnov statistic was employed as a population classifier. Simulations were run on artificial data with two-dimensions, four populations and three classes. A quantitative analysis of the adaptive classifier's dependence on population separation, training set size, and stack length determined optimal values for the different parameters involved. The technique was also applied to a real produce sorting problem, e.g. an automatic machine for sorting dates by machine vision in an Israeli date packinghouse. Extensive simulations were run on actual sorting data of dates collected over a 4 month period. In all cases, the results showed a clear reduction in classification error by using the adaptive technique versus non-adaptive sorting.

Resumen

The Computerized Delivery Sequence (CDS) file contains listings for nearly all addresses in the United States. Survey researchers use the CDS as a sampling frame from which to draw an address-based sample (ABS). More than 700,000 addresses on the CDS are marked as drop points, which are mail receptacles shared by multiple housing units (drop units). Drop points are a challenge to sample and present a potential source of error because of their "one-to-many" relationships. Several techniques have been developed to overcome this challenge, including deleting them from the frame or sampling all units at a given drop point. This paper serves as an introduction to these challenges, discusses the pros and cons to each "solution," and provides a list of best practices.

Texto completo

Resumen

The main objectives were (1) to develop, implement and validate control procedures that would make it possible to maintain year-round air temperature and humidity at levels suitable for crop cultivation in greenhouses operating in arid and semi-arid regions and (2) to investigate the influence of the operational flexibility of the fogging system on the performance of the system. With respect to the development of climate controllers, we developed a new control approach according to which ventilation is used to maintain the enthalpy of the greenhouse air and fogging is used to adjust the humidity ratio inside the greenhouse. This approach is suitable mostly for greenhouses equipped with mechanized ventilation, and in which the air exchange rate can be controlled with enough confidence. The development and initial validation of the controllers were performed in a small experimental greenhouses located at the Agricultural Research Organization and very good tracking were obtained for both air temperature and relative humidity (maximum mean deviations over a 10-min period with constant setpoints lower than 2.5oC and 5% relative humidity). The robust design approach used to develop the controllers made it possible to transfer successfully these controllers to a much larger semi-commercial greenhouse located in the much drier Arava region. After only minimal adjustments, which did not require lengthy dedicated experiments, satisfactory tracking of the temperature and humidity was achieved, with standard deviation of the tracking error lower than 1oC and 5% for temperature and relative humidity, respectively. These results should help promote the acceptance of modern techniques for designing greenhouse climate controllers, especially since given the large variety of greenhouse structures (shape, size, crop system), developing high performance site-specific controllers for each greenhouse is not feasible. In parallel to this work, a new cooling control strategy, which considers the contribution of humidification and cooling from the crop, was developed for greenhouses equipped with natural ventilation. Prior to the development of the cooling strategy itself, three evapotranspiration models were compared in terms of accuracy and reliability. The cooling strategy that has been developed controls the amount of fog introduced into the greenhouse as well as the percentage of vent openings based on the desired vapor pressure deficit (VPD) and enthalpy, respectively. Numerical simulations were used to compare the performance of the new strategy with a constant fogging rate strategy based on VPD, and on average, the new strategy saved 36% water and consumed 30% less electric energy. In addition, smaller air temperature and relative humidity fluctuations were achieved when using the new strategy. Finally, it was demonstrated that dynamically varying the fog rate and properly selecting the number of nozzles, yields additional water and electricity savings.

Resumen

This module, aimed at helping both English as a Foreign Language (EFL) teachers and their students, is the result of a qualitative, applied, transversal and constructivist research conducted with Open Lingua teachers. One of the objectives of said research was to establish the factors that favored and hindered the curriculum integration of open access bilingual dictionaries in that specific EFL context in order to design and implement some pedagogical and didactic initiatives that would foster the effective use of those lexical tools. The present module was a fundamental element within the series of proposals that arose along the research. Its main objective was to provide the teachers with the necessary conceptual knowledge and didactic strategies and resources to teach their students how to use that kind of online dictionary with higher degrees of ease, enjoyment, and efficiency, and, thus, to reduce the frequency of look up errors. This module offers a variety of digital resources, handouts, and hands-on and assessment activities that can greatly facilitate their job when teaching dictionary skills to their students.

Texto completo

Resumen

This is a study of nonconformances experienced by a laboratory of a pharmaceutical manufacturing facility in East Africa. There has been an increase in nonconformances from 216 nonconformances in 2017 to 229 in 2018 and by September 2019, 306 nonconformances were already logged. Increasing nonconformances result in delayed release of tested materials and many resources are wasted (e.g. chemicals, man hours and equipment). Analysts become frustrated, which may result in inexhaustive investigations. Understanding the reason for the increase in nonconformances will enable the facility to derive effective solutions to the identified causes, hence reducing the number of nonconformances and improving the productivity and morale of employees. This quantitative, nonexperimental, longitudinal survey study was intended to evaluate and understand the reason for increasing nonconformances. Trends of the nonconformances, previous investigations, procedure for investigation and the training given to analysts have been reviewed. Laboratory incidences were the most recurring nonconformances; and these were mainly caused by analyst errors. Corrective and Preventive Actions (CAPAs) were derived by cross functional teams whenever root causes were identified. Procedure for investigation of nonconformances refers to investigative tools. Identification of root causes to nonconformances recently became mandatory. Analysts have limited advanced industrial training on investigation of nonconformances. Another study should be carried out to understand the cause of analyst errors. The study can be rolled out to other departments at the manufacturing facility to create similar improvements. Analysts should enroll into advanced courses of industrial pharmacy to gain advanced industrial skills which they can apply in investigations to find root causes to nonconformances.

Resumen

The initial wetting of a reservoir sets a limit for the EOR potential during water-based recovery operations and “Smart Water” injection. For this reason, an improved understanding of the factors influencing the wetting can help to control and better forecast oil production during water-based floods. To preserve and reproduce the original reservoir wettability is a challenging task and wrong cleaning and core restoration procedures can lead to incorrect wettability estimations and thus induce serious errors when evaluating the initial wettability of a reservoir system or its EOR potential by water-based methods. Thereby, there is a need to improve the chemical knowledge on interactions among the rock, brine and fluids present in reservoir systems. This will help to understanding the influence of the parameters affecting wettability during cleaning and core restoration processes. Understanding which are the main parameters influencing oil recovery processes is of great relevance. The objective of this document is to provide suggestions for added-value experiments, complementing and challenging the standard RCA and SCAL procedures, prior to performing experimental research in which wettability and wettability alteration processes are important. Lessons learned will be highlighted and new ideas to optimize core restoration protocols to preserve and closely reproduce wettability are put forward. These recommended practices target core restoration procedures after the core material has been received in the laboratory. The target audience for this document is engineers and scientists with an interest in core preparation for wettability studies.
