Abstract:
Event study is a widespread technique for testing the semi-strong form of the market efficiency hypothesis. Among traditionally studied events, changes in corporate credit ratings by rating agencies have a special importance, since rating agencies use both publicly available and insider information. Studies of developed and emerging markets point to different reactions of stock prices to rating upgrades and downgrades and identify several factors affecting the scale of this effect, including the size and liquidity of the stock market, the level of regulation of the industry, the market capitalization of the company, the status of the rating agency, and others. On the Russian market, the impact of credit rating upgrades and downgrades on stock prices has not been investigated so far. Ongoing studies of other events affecting stock prices show that the market’s reactions are pretty much in line with those of developed markets, despite its immaturity, limited transparency, high volatility, narrowness and low liquidity, as well as the small number of significant events. In this article, we evaluate the level of efficiency of the Russian stock market and analyse the reaction of stock prices to changes in issuer credit ratings by international rating agencies using the traditional event study methodology in a narrow event window of 31 days over the period 2016–2020 on a sample of 49 public companies. We show that credit rating upgrades do not lead to statistically significant positive abnormal returns. Visual analysis demonstrates that rating downgrades result in substantial negative abnormal returns. This effect varies for financial and non-financial companies and companies with low and high capitalization yet differs from the effects observed for developed markets; nevertheless, these abnormal returns are not statistically significant. Still, there are grounds to conclude that the Russian stock market is not efficient in the semi-strong form and is closer in its characteristics to emerging markets, which is important information for investors, as it permits them to develop profitable trading strategies.

AbstractThe article addresses the issue of stress testing based on the probability of bankruptcy and a rating migration matrix. The analysis is conducted on a sample of listed companies in Poland in the years 1998–2016, and the forecasts are made for the years 2016–2018. Particular attention is paid to how the variable on which rating migration matrices are developed is defined. Stress tests are carried out on variables derived from rating migration matrices and economic indicators. The study provides information on the methodology for stress testing.

Abstract:
Purpose This paper aims to provide a theoretical explanation of why credit rating agencies typically disclose credit risk of issuers in classes rather than publishing the qualitative ranking those classes are based upon. Thus, its goal is to develop a better understanding of what determines the number and size of rating classes. Design/methodology/approach Investors expect ratings to be sufficiently accurate in estimating credit risk. In a theoretical model framework, it is therefore assumed that credit rating agencies, which observe credit risk with limited accuracy, are careful in not misclassifying an issuer with a lower credit quality to a higher rating class. This situation is analyzed as a Bayesian inference setting for the credit rating agencies. Findings A disclosure in intervals, typically used by credit rating agencies results from their objective of keeping misclassification errors sufficiently low in conjunction with the limited accuracy with which they observe credit risk. The number and size of the rating intervals depend in the model on how much accuracy the credit rating agencies can supply. Originality/value The paper uses Bayesian hypothesis testing to illustrate the link between limited accuracy of a credit rating agency and its disclosure of issuers’ credit risk in intervals. The findings that accuracy and the objective of avoiding misclassification determine the rating scale in this theoretical setting can lead to a better understanding of what influences the interval disclosure of major rating agencies observed in practice.

Abstract:
Purpose Empirical tests of Hersey and Blanchard’s situational leadership theory (SLT) have demonstrated that the assessment of follower competence and commitment, critical contextual features dictating optimal leadership style, poses several problems in testing the validity of this theory. As well, most previous studies have used leader rating as the only information source in making these assessments. The purpose of this paper is to use the degree of agreement between leader rating and follower self-rating to determine follower competence and commitment, and consequently an optimal leadership style. Design/methodology/approach Survey data collected from both supervisors and employees in business organizations in Norway were analyzed to test the predictions put forward in SLT. Findings The results show that SLT principles are supported when leader rating and follower self-rating are congruent. However, no support was obtained for Blanchard’s suggestion to apply followers’ self-ratings of competence and commitment in the case of discrepant ratings of follower development level. But data do support the contention that leader assessment would be a better basis for providing followers with appropriate direction and support. Originality/value So far SLT has been a very popular but as yet under-researched theory. An important contribution of the present study is by making SLT an evidence-based theory, as opposed to just being intuitively sound. As such, the authors think SLT in an updated “convergent” version should be applied in organizations and taught in leadership development programs.

Abstract:
Abstract Evaluators who use the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Sixth Edition, should understand the significant changes that have occurred (as well as the Clarifications and Corrections) in impairment ratings for disorders of the cervical spine, thoracic spine, lumbar spine, and pelvis. The new methodology is an expansion of the Diagnosis-related estimates (DRE) method used in the fifth edition, but the criteria for defining impairment are revised, and the impairment value within a class is refined by information related to functional status, physical examination findings, and the results of clinical testing. Because current medical evidence does not support range-of-motion (ROM) measurements of the spine as a reliable indicator of specific pathology or permanent functional status, ROM is no longer used as a basis for defining impairment. The DRE method should standardize and simplify the rating process, improve validity, and provide a more uniform methodology. Table 1 shows examples of spinal injury impairment rating (according to region of the spine and category, with comments about the diagnosis and the resulting class assignment); Table 2 shows examples of spine impairment by region of the spine, class, diagnosis, and associated whole person impairment ratings form the sixth and fifth editions of the AMA Guides.

Abstract:
The paper empirically examines whether the international rating influences the rate of exchange of an economy in the long run? The paper employs Autoregressive Distributed Lag (ARDL) Bounds testing methodology on the exchange rate of China and contemporary international rating, using time series data from 1996Q1 to 2016Q4. The empirical analysis confirms the presence of a cointegration relationship between country rating and the exchange rate. To be more specific; corruption index, credit rating, and inflation are significantly and negatively cointegrated with the exchange rate of China. Conversely, consumer confidence is uncorrelated with the exchange rate over the long run. The paper focuses only on the exchange rate of CNY-USD; this may limit the generalizability of results for exchange rate with other nations. Nevertheless, the results add to the exchange rate determinants literature by including country-rating indicators in the analysis. Prior literature documents that there is some relationship between inflation and exchange rate. This research is novel in the application of robust ARDL and bounds testing to examine the long and short-run association of country rating of China with its exchange rate, after controlling for inflation.

Abstract:
The choice of a rolling bearing for a particular application relies on performance rating parameters as the static, the dynamic, and the fatigue limit load of bearings. The values of these parameters define the calculated performance of the bearing. Endurance testing of high-quality rolling bearings has been used for the development of rolling bearing performance standards like the ISO 281 and ISO 76 that are commonly used throughout the industry. However, standard test methods for the measurement and validation of load ratings of rolling bearings are not available in the standards. This leads to the undifferentiated use of the “status of the art” standardized performance to the very large variety of rolling bearing types and qualities that are produced today. The current paper revisits the origin, definition, and development of rolling bearing performance parameters. A numerical study for the determination process of bearing load ratings is carried out. The results are compared with standardized values and values quoted by bearing manufacturers. This provides an overview of the load rating practices that are in use. The limitations and possible improvements of the present methodology are discussed.

Abstract Deck boards are key components in outdoor decks and balconies. The deck board market is shared primarily between solid-sawn and composite products. The focus of this article is solid-sawn wood deck boards, which are manufactured in North America as span-rated products following a policy promulgated by the American Lumber Standard Committee (ALSC). The latest revision of the ALSC span rating policy was approved in November 2020, and this article describes the technical basis for the changes. Distributed and concentrated design loads specified in the policy exceed building code minimum requirements. In addition, dynamic load amplification due to deck occupants is included in the new policy. Testing was performed to characterize the effects of partial fixity at joist supports caused by screw fasteners and was incorporated into the span rating methodology.

Abstract:
The article contains an overview of the essence, history, components, scenarios, methodology and results of stress testing of the Ukrainian banking system. The purpose of this paper is to explore and analyze existing approaches to stress testing as a method of macro-prudential policy of the Central Bank, to determine the results of quantitative risk assessment and financial stability of banks and their readiness to have sufficient capital to cover losses in various macroeconomic scenarios, as well as to develop a model of integrated assessment and rating of banks based on the results of stress testing. In order to summarize the results of the study, a model of integrated assessment was developed and a rating of banks was built based on the analysis of their financial stability, capital adequacy and readiness to withstand the crisis. To solve the problem of qualitative analysis of the stress-testing results in terms of a significant number of indicators and calculations a simulation of the integral indicator is proposed which helps information users group the data, obtain a generalized assessment and form a rating of banks according to the financial stability reserve.

Abstract:
Purpose The purpose of this paper is to discover if there is a correlation between scores on the Beck’s Depression Inventory (BDI) and the Cognitive and Physical Functioning Questionnaire (CPFQ) scores of 43 patients with major depression. Design/methodology/approach In total, 43 adult patients with major depression were evaluated during their regularly scheduled outpatient appointment in a mental health clinic. Findings There was an R2 value of 0.6544 between the patients’ scores, a moderate-to-strong correlation which matches other observations that cognitive impairment increases in conjunction with severity of depression. This correlation lends further clinical support to the legitimacy of using the CPFQ as a simpler alternative to traditional neuropsychological testing, with further testing of the correlation between CPFQ and traditional neuropsychological testing results being a worthwhile potential field of study. Originality/value Cognitive dysfunction is a frequent comorbidity in patients with depression, but while there is a brief and effective self- assessment for depression, the BDI, in common use, there is no equivalent test for cognitive dysfunction, and physicians are forced to rely on less accessible methods of neuropsychological testing.

Institutions of the Farm Credit System (FCS) focus on risk-based lending in accordance with regulatory direction. The rating of risk also assists retail staff in loan approval, risk-based pricing, and allowance decisions. FCS institutions have developed models to analyze financial and related customer information in determining qualitative and quantitative risk measures. The objective of this thesis is to examine empirical account data from 2006-2012 to review the probability of default (PD) rating methodology within the overall risk rating system implemented by a Farm Credit System association. This analysis provides insight into the effectiveness of this methodology in predicting the migration of accounts across the association’s currently-established PD ratings where negative migration may be an apparent precursor to actual loan default. The analysis indicates that average PD ratings hold relatively consistent over the years, though the distribution of the majority of PD ratings shifted to higher quality by two rating categories over the time period. Various regressions run in the analysis indicate that the debt to asset ratio is most consistently statistically significant in estimating future PD ratings. The current ratio appears to be superior to working capital to gross profit as a liquidity measure in predicting PD rating migration. Funded debt to EBITDA is more effective in predicting PD rating movement as a measure of earnings to debt than gross profit to total liabilities, although the change of these ratios over time appear to be weaker indicators of the change in PD rating potentially due to the variable nature of annual earnings of production agriculture operations due to commodity price volatility. The debt coverage ratio is important as it relates to future PD migration, though the same variability in commodity price volatility suggests the need implement multi-year averaging for calculation of earnings-based ratios. These ratios were important in predicting the PD rating of observations one year into the future for production agriculture operations. To further test the predictive ability of the PD ratings, similar regression analyses were completed comparing current year rating and ratios to future PD ratings beyond one year, specifically for three and five years. Results from these regression models indicate that current year PD rating and ratios are less effective in predicting future PD ratings beyond one year. Furthermore, because of the variation in regression results between the analyses completed for one, three and five years into the future, it is important to regularly capture ratio and rating information, at least annually.

Abstract:
Sequential methods aim to update beliefs about a set of parameters given new blocks of data that arise in sequence. Early research in this area was motivated by the case where the blocks of data arise in time and as a result of observing an underlying dynamical system, but an important modern application is in the analysis of large datasets. This thesis considers both the design and application of sequential methods. A new adaptive sequential Monte Carlo (SMC) methodology is presented. By incorporating adaptive Markov chain Monte Carlo (MCMC) moves into the SMC update, it is possible to utilise the heuristic, computational and theoretical advantages of SMC to make gains in sampling efficiency. The new method is tested on the problem of Bayesian mixture analysis and found to outperform an adaptive MCMC algorithm in 5 out of 6 of the situations considered. Theoretical justification of the method, guidelines for implementation and a condition for convergence are provided. When the dimensionality of the parameter space is high, methods such as the adaptive SMC sampler do not work well. In such cases, sequential data analysis can proceed with statistical models that are amenable to the exact or approximate filtering recursions. The two situations considered here will be the rating of sports teams and players. A new method for rating and selecting teams for the NCAA basketball tournament is considered. The selection of teams is important to University institutions in the United States, as admittance brings academic as well as sports-related financial benefits. Currently the selection process is undertaken by a panel of expert voters. The new method is in the main found to agree with these pundits, but in the seasons considered a small number of cases are highlighted where injustice to the team was evident. Also considered is the rating of professional basketball players. A new method is developed that measures a player's offensive and defensive ability and provides a means of combining this information into an overall rating. The method uses data from multiple seasons to more accurately estimate player abilities in a single season. Injustice in the assigning of NBA awards in the 2009 season is uncovered, but the research also highlights one possible reason for this: the commonly cited box-score statistics contain little information on defensive ability.

Abstract:
Radio Frequency Identification (RFID) is a promising technology for process automation and beyond that capable of identifying objects without the need for a line-of-sight. However, the trend towards automatic identification of objects also increases the demand for high quality RFID applications. Therefore, research on testing RFID systems and methodical approaches for testing are needed. This thesis presents a novel methodology for the system level test of RFID applications. The approach called ITERA, allows for the automatic generation of tests, defines a semantic model of the RFID system and provides a test environment for RFID applications. The method introduced can be used to gradually transform use cases into a semi-formal test specification. Test cases are then systematically generated, in order to execute them in the test environment. It applies the principle of model based testing from a black-box perspective in combination with a virtual environment for automatic test execution. The presence of RFID tags in an area, monitored by an RFID reader, can be modelled by time-based sets using set-theory and discrete events. Furthermore, the proposed description and semantics can be used to specify RFID systems and their applications, which might also be used for other purposes than testing. The approach uses the Unified Modelling Language to model the characteristics of the system under test. Based on the ITERA meta model test execution paths are extracted directly from activity diagrams and RFID specific test cases are generated. The approach introduced in this thesis allows to reduce the efforts for RFID application testing by systematically generating test cases and the automatic test execution. In combination with meta model and by considering additional parameters, like unreliability factors, it not only satisfies functional testing aspects, but also increases the confidence in the robustness of the tested application. Mixed with the instantly available virtual readers, it has the potential to speed up the development process and decrease the costs - even during the early development phases. ITERA can be used for highly automated testing, reproducible tests and because of the instantly available readers, even before the real environment is deployed. Furthermore, the total control of the RFID environment enables to test applications which might be difficult to test manually. This thesis will explain the motivation and objectives of this new RFID application test methodology. Based on a RFID system analysis it proposes a practical solution on the identified issues. Further, it gives a literature review on testing fundamentals, model based test case generation, the typical components of a RFID system and RFID standards used in industry.

Full text
Abstract:
Concolic testing is a technique that combines concrete and symbolic execution in order to generate inputs that explore different execution paths leading to better testing coverage. Concolic testing tools can find runtime errors fully automatically using available type specifications. The type specifications in a function define the type of each input. However, most specification languages are never expressive enough, which can lead to runtime errors caused by malformed inputs (i.e. irrelevant errors). Moreover, logic errors causing a program to operate incorrectly without crashing cannot be reported automatically. A universal methodology for any programming language is proposed. Preconditions force the concolic execution to generate well formed inputs before testing a function. On the other hand, postconditions lead to a runtime error when a program operates incorrectly, helping to find logic errors. The results obtained using the concolic testing tool CutEr, in the functional programming language Erlang, show how a program is only tested using well formed inputs specially generated to try to violate the defined postconditions.

Full text
Abstract:
With the continuing growth in energy consumption worldwide, the move towards a European wide super grid will result in significant changes in how modern transmission and distribution networks are operated. Fundamental to this is the need to accurately know or determine the available ampacity of high voltage cable circuits, because huge bulk power volumes need to be transmitted between maritime nations through dc power cables. Therefore, an accurate cable rating becomes paramount towards an efficient and safe operation of transmission networks, while the finance for large scale network construction schemes is limited. Although the standardised thermal-limited rating has been successfully implemented for traditional ac cable networks for over 50 years, the move towards dc cable transmission imposes extra physical constraints on the cable rating, which are not considered by standard rating approaches. The two main concerns are the potential dielectric electrical breakdown prior to a normal thermal runaway and the development of dielectric cavities during cable cooling. In addition, the thermal-limited rating of submarine dc cable crossings, within a complex marine environment, requires an advanced numerical modelling method, where the traditional IEC thermal-limited rating method does not apply. Besides the technical value, significant interest exists both within the electrical power industry and organizations such as Cigré and IEC, because this work will inform future international standards for rating high voltage dc cables. Considering the dielectric electrical stress constraint as the limiting factor for cable ratings, an analytical electrical stress-limited rating method has been developed and successfully benchmarked by numerical simulations for a practical cable design. This method allows ratings to be calculated against a criterion of maximum dielectric electrical strength. Considering the dielectric cavity creation threshold as the limiting factor for cable ratings, a comprehensive study has been conducted, including thermal dynamics, theory of elasticity and electrical circuit theory. Subsequently, the analytical calculation of the cable internal pressure has been originally developed, together with a concept of the mechanical pressure-limited rating. The method has been successfully demonstrated for a practical cable design, yielding a rating which prevents the creation of cavity due to potential plastic deformations of the cable sheath. When crossings are inevitably installed, cables are pushed towards their thermal limit, as a result of the mutual heating. In order to accurately rate these circuits under various ambient conditions; Finite Element Analysis (FEA) methods have been developed. Compared to the traditional IEC calculation, FEA modelling provides a more reasonable and accurate solution, by releasing idealistic assumptions in the IEC method. In addition, a systematic cable rating strategy has been suggested and successfully demonstrated through rating submarine high voltage dc cable crossings, which considers highly coupled physics: thermal, electrical and mechanical. In summary, this thesis contributes towards the modern rating methodology development for hvdc mass impregnated cable circuits, under a purpose of efficient and reliable long-term operation.

Abstract:
In this thesis, we present a system-on-a chip testing methodology. The system consists of a wrapper, test access mechanism and the cores under test. The cores include the ISCAS sequential and combinational benchmark circuits. At the gate level, stuck at fault model is used to detect faults. The wrapper separates the circuit under test from other cores. The test access mechanism transports the test patterns or test vectors to the desired circuit under test and then transports the responses back to the output pin of the SOC. The faults are then injected using the fault simulator that generates test for the circuit under test. Out of the many TAM design methods, we implemented the TAM as a plain signal transport medium, which is shared by all the cores in the system-on-chip. Once the dedicated TAM lines are set to the circuit under test, fault simulation is done. Each circuit in an SOC is independently tested for its fault coverage. The isolation of the circuit under test from the others is taken care by the program running in the background. We were able to simulate the whole SOC testing and get satisfactory fault coverage for the circuits under tests.

Abstract:
Road safety is influenced by the dynamic performance of heavy trucks during emergency maneuvers that involve abrupt changes in direction and velocity. In this context, rating of trucks performance under such situations becomes crucial to promote safer roads. Present test methods to evaluate trucks performance during braking and lane change maneuvers involve substantial monetary and time investments, and are limited to certain critical trucks and cargo. A more general methodology to evaluate a wider range of vehicles under diverse situations is thus necessary. In this paper the conceptual design of a truck testing facility is proposed to characterize and compare the dynamic performance of the vehicles under emergency maneuvering, as a function of the components’ properties, payload conditions and overall truck design. The equipment consists of a moving platform on which the vehicle is mounted, including load cells to measure tire loads. The motion of the platform can simulate steering maneuvers by providing lateral and yaw excitations.

Abstract:
Many aging liquid pipeline systems face demands to increase viscosity and/or flow capacity requirements. This paper presents a methodology to assure old pipelines’ up-rating serviceability by means of an optimizing integrity evaluation procedure where metal loss defects, reported by smart pig inspection, are assessed based upon maximum pressure profiles. The referred methodology comprises the following steps: 1. simulate the most severe pressure profiles scenarios for both steady and transient states and define maximum construct pressure envelopes; 2. build up representative equations of the maximum pressures observed at each profile point to steady/transient conditions; 3. assess pipe defects population reported by recent smart pig inspection considering the maximum pressure and the appropriate failure model; 4. determine rehabilitation hydrostatic testing pressures required to validate the new operating conditions; 5. re-assess pipe defects population considering the hydrostatic testing pressures. To illustrate the methodology applications, three case studies are presented, all carried out on pipelines older than 30 years. In order to accomplish the increased required capacity, four additional pump facilities were design and erected. Over thirty thousand metal loss defects (from ILI reported population greater than one million) were effective assessed for hydrostatic testing and operating conditions — considering individual pressure calculation. Regarding operating conditions, repair scenarios were constructed considering rehabilitation for a time interval of 5 years (based on estimated corrosion growth). The hydraulic simulations and the metal loss defect assessment where performed using, respectively, Pipeline STONER Simulator 9.3 and PLANPIG 2.0 software’s. This methodology has been successfully applied by PETROBRAS TRANSPORTE S.A. on revamping of corroded pipelines: despite the cases’ corrosion damage severity and the lack of conservatism on hydrostatic testing modeling, no test break was observed at the two tested lines and the required repairs number was dramatically reduced as compared to the traditional “as good as new” rehabilitation approach.

Abstract:
A new vibration-based multiaxial fatigue testing methodology for assessing high cycle turbine engine material fatigue strength at various stress ratios is presented. The idea is to accumulate fatigue energy on a base-excited plate specimen at high frequency resonant modes and to complete a fatigue test in a much more efficient way at very low cost. The methodology consists of: (1) a topological design procedure, incorporating a finite element model, to characterize the shape of the specimens for ensuring the required stress state/pattern, (2) a vibration feedback empirical procedure for achieving the high cycle fatigue experiments with variable-amplitude loading, and finally (3) a yielding procedure for achieving various uniaxial stress ratios. The performance of the methodology is demonstrated by the experimental results from mild steel, 6061-T6 aluminum, and Ti-6Al-4V plate specimens subjected to fully reversed bending for both uniaxial and biaxial stress states. Results are compared with those produced using traditional fatigue test machines.

Full text
Abstract:
Abstract A new approach was implemented to confirm the start of ductile tearing relative to assessments by other methods such as direct-current Electric Potential (d-c EP) method in coupon specimens. This approach was developed on the Key-Curve methodology by Ernst/Joyce and is similar to the ASTM E-1820 Load Normalization procedure used to determine J-R curves directly from load versus Load-Line Displacement (LLD) record of the test specimen. It is consistent with Deformation Plasticity relationships for fully plastic behavior. Using this Experimental Key-Curve method, crack initiation can be determined directly from load versus LLD data or load versus Crack-Mouth Opening Displacement (CMOD) obtained from a fracture test without the need for additional instrumentation required for crack initiation detection. It is based on the fact that plastic deformation of homogeneous metals at the crack tip follows a power-law function until the crack tearing initiates. Crack tearing initiation is determined at the point where the power-law fit to the load versus plastic part of CMOD or LLD curve deviates from the total experimental load versus plastic-CMOD or LLD curve. The procedure for fitting of the data requires some care to be exercised such that the fitted data is beyond the elastic region and early small-scale plastic region of the Load-CMOD or Load-LLD curve but include data before crack initiation. An iterative regression analysis was done to achieve this, which is shown in this paper. The iterative fitting in this region typically results with a coefficient of determination (R2) values that are greater than 0.990. This method can be either used in conjunction with other methods such as direct-current Electric Potential (d-c EP) or unloading-compliance methods as a secondary (or primary) confirmation of crack tearing initiation (and even for crack growth); or can be used alone when other methods cannot be used. Furthermore, when using instrumentation methods for determining crack-initiation such as d-c EP method in a fracture toughness test, it is good to have a secondary confirmation of the initiation point in case of instrumentation malfunction or high signal to noise ratio in the measured d-c EP signals. In addition, the Experimental Key-Curve procedure provides relatively smooth data for the fitting procedure, while unloading-compliance data when used to get small crack growth values frequently has significant variability, which is part of the reason that JIC by ASTM E1820 is determined using an offset with some growth past the very start of ductile tearing. In this work, the Experimental Key-Curve method had been successfully used to determine crack tearing initiation and demonstrate the applicability for different fracture toughness specimen geometries such as SEN(T), and C(T) specimens. In all the cases analyzed, the Experimental Key-Curve method gave consistent results that were in good agreement with other crack tearing initiation measuring method such as d-c EP but seemed to result in less scatter.

Abstract:
The work presented here describes the selection process of mobile phones with better usability for use in emergency situations in Portugal. In emergency management, communications are a fundamental asset for limiting the consequences of risky situations. Since mobile phones have revolutionized the way people communicate they can constitute an opportunity to be used in information exchange during emergency situations. In this study the mathematical methodology developed by (Jeelani, 2011) - which holistically represents human factors’ issues associated with the use of mobile phone in emergency - was adapted to the Portuguese context. This methodology allows the rating of mobile phones in terms of suitability for use in emergency situations, having the satisfaction of user needs as a main priority. The methodology used in this study comprehends three phases: identification of the more important features of mobile phones for use in emergency situations; determination of the selection factors relative importance, using Analytic Hierarchy Process; and usability testing of five mobile phones using Cognitive Walkthrough protocol, with 20 individuals.

Abstract:
This paper addresses a methodology to maintain pressure vessels per ASME Section VIII, Division 1 Code and jurisdictional requirements, for new and existing pressure vessels. The pressure vessels discussed are drums, towers, shell & tube heat exchangers, and air-cooled exchangers, all designed and built per ASME Section VIII, Division 1. The methodology applies to vessels in refineries, gas plants, oilfield facilities, and chemical plants. Vessel adequacy is maintained via Codes, non-destructive testing, materials, inspection, company standards, welding procedures, inspection/maintenance standards, and jurisdictional requirements. Unique maintenance software, “PVCalc”, can aid in vessel calculations, to calculate the pressure rating, and remaining life, per the original edition of the Code under which the vessel was built. New vessel designs should be thoroughly reviewed, as the author’s experience over the last eight years is that approximately 65 to 80 percent of all vessel designs contain design errors (mostly minor) per ASME Code.

Abstract:
The MCFC system of BOP (Balance of Plant) is contained various mechanical equipments. One of the equipments of the heat exchangers is important component for efficiency and cost. In MCFC system, several heat exchangers are used according to the application. Most typical heat exchanger is the humidifier in BOP for MCFC, which is named for the humidifier because it is to preheat the fuel and water so that a reactor will convert some of the incoming fuel to hydrogen. Then, hot side fluid service is used the exhausted gas from the fuel cell and cold side fluid service is the fuel and water. The operation temperature range is about 25∼500 Celsius Degree.[1] This heat exchanger has the problems of multiphase fluid and phase change heat transfer. So it is necessary to analyze the heat transfer characteristics and to propose the reasonable design methodology for the humidifier. In this study, the thermal characteristic for the humidifier is estimated by using commercial tool of heat exchanger design, rating and simulation. Also this study presents the results for test facility of fabrication and for testing.

Full text
Abstract:
Abstract Objectives/Scope During casing installation and drilling operations, Oil Country Tubular Goods (OCTG) strings are often rotated inside deviated wellbores, generating cyclic bending loading that could lead to fatigue damage. This phenomenon has been previously studied and understood. The completion of multistage fractured horizontal wells (MFHW) involves tens of fracture operations (an ever growing number) as part of the stimulation program in order to maximize production. These fracture operations involve a combination of cyclic pressures and tension loading in the production casing, through which they are conducted, with maximum loads often repeatedly reaching the upper limit of the pipe body performance ratings. This process of cyclic pressure and tension loading near the upper limit of the pipe body performance is the subject of this work. In unconventional plays, where MFHW are the standard approach, both cyclic bending due to rotation and cyclic burst and tension due to multiple fracturing operations are applied on OCTG strings. This combination may lead to a failure mode in which a crack opens due to material fatigue during rotation or fracturing cycles, and subsequently propagates (to failure) during the demanding fracturing stages. Methods, Procedures, Process As it would be expected during any technological evolution, the industry has seen an increase in casing failures during hydraulic fracturing, often not explainable by the current understanding of loads scenarios present in wellbores. Some of these events could be associated to the failure mode described above. Despite the potential risk introduced by this failure mode, to date, there is no standardized testing methodology available to evaluate the resistance of pipes and connections to this loading sequence. Results, Observations, Conclusions In order to cover this gap, a testing sequence aimed at replicating actual operating conditions was developed and deployed by the authors. This includes evaluating the resistance of a premium connection to rotation through a curved hole, and subsequent burst and tension cycles. The methodology and results are presented in this paper. Novel/Additive Information Through this testing approach, operators, manufacturers, and laboratories alike, can ensure the performance and reliability of OCTG, which are key elements in the well construction process. As main observations, all tested specimens successfully passed this very demanding testing sequence, aimed to replicate operative conditions during installation and subsequent stimulation operation.

Full text
Abstract:
Abstract This paper reviews field data where high-frequency torsional oscillation (HFTO) was seen on previous bit runs and hypothesizes on features or design metrics that may have directly influenced this vibration. This paper investigates four metrics of bit design: Cutter wear, shear length:shear area ratio, choice of secondary cutter material, and effective backrake. Hypotheses are established linking these metrics to HFTO, and then data from field runs is shown to correlate the hypotheses. At this point, a bit was designed and manufactured to put the HFTO avoidance hypotheses into practice. Prior to laboratory testing, a theoretical model is used to identify resonant torsional frequencies. A series of laboratory experiments followed to test the hypotheses and demonstrated that there is correlation between all factors, but in one case is counter to the hypothesis. This information is of use when selecting or designing bits in environments where HFTO is known to occur. The findings may also assist in explaining performance that's below expectations where HFTO is not able to be explicitly measured.

Full text
Abstract:
Ultra-high bypass ratio turbofans offer significant reductions in fuel and pollution due to their higher propulsive efficiency. Short intakes might lead to a stronger fan-intake interaction, which creates uncertainty in stability at off-design conditions. Due to the prohibitive cost of full-scale experimental testing, subscale testing in wind tunnels is used to understand this behaviour. The low Reynolds number of subscale models results in unrepresentative laminar shock-boundary layer interactions. The boundary layer state thus needs to be conditioned to better represent full-scale transonic fans. This paper proposes the use of an inexpensive and robust flow control method for the suction side of a fan blade. Design guidelines are given for the location and height of the discrete roughness elements used to control the boundary layer state. This paper also presents a rapid experimental validation methodology to ensure and de-risk the application of the boundary layer trip to 3D rig blades. The experimental methodology is applied to a generic aerofoil representative of a fan tip section. The experimental method proves that it is possible to reproduce boundary layers and pressure distributions of a full-scale fan blade on a 1/10 subscale model. The results obtained confirm that the boundary layer trip method successfully promotes transition at the location representative of full-scale blades, avoiding unrepresentative laminar shock wave boundary layer interactions. This highlights the importance of conditioning boundary layers in low Reynolds number fan rig testing.
