Abstract:
The dynamic penetration test (DPT) and the Menard pressuremeter test (PMT) have been widely used in geotechnical survey of deep soils for megadam foundations in western China. The DPT measures are not well utilized due to the lack of correction factors and of empirical relationships for deep soils. This study investigates the relationships between the corrected DPT blow counts ( N 120 ′ ), pressuremeter modulus (EPMT), limit pressure (pL), deformation modulus (E0), and bearing capacity (fak) derived from the PMT results. Meanwhile, a nonlinear regression model is developed to predict the DPT correction factor (a) based on the raw DPT blow counts (N120) and the rod length (L) by integrating the available correction factors for shallow gravelly soils suggested by the code provisions and the deep soil data in this work. It is concluded that the proposed DPT correction factors match well with the code suggestions and the new compiled dataset, and the corrected DPT blow counts can be used to reasonably predict the engineering properties of deep sand and clay soils. Although the proposed correlations need to be tested among different soil types and regions, the results shed the light on in situ geotechnical tests and data utilization for deep and thick overburden.

Abstract:
Evidence suggests that optimism has a positive impact on health status. Attentional bias modification (ABM) may be beneficial for enhancing optimism, but its effective application requires a detailed investigation of the association between attentional bias and optimism. This study aimed to determine the association between attentional bias and optimism based on different task types. Eighty-four participants completed the attentional bias measures using the dot-probe task (DPT), emotional visual search task (EVST) paradigms, and psychological assessments. Optimism was assessed using the Life Orientation Test-Revised with subscales for optimism and pessimism. Pearson’s correlation coefficient and multivariate linear regression analysis were applied to investigate the association between optimism and attentional bias. Neither the attentional bias derived from DPT nor EVST was significantly correlated with optimism total score or subscales. Regression analysis also showed no association between attentional bias and optimism (DPT, β = 0.12; EVST, β = 0.09), optimism subscales (DPT, β = 0.09; EVST, β = 0.17), or pessimism subscales (DPT, β = −0.10; EVST, β = 0.02). Our findings showed no evidence that attentional biases derived from either the DPT or EVST measures are associated with optimism or pessimism. Further studies are needed to effectively adapt the ABM to enhance optimism.

Abstract:
Objective: The aim of the study was to evaluate the accuracy of the diagnostic Pap test (DPT) on three slides and punch biopsy and endocervical curettage (PB/ECC) compared with the final biopsy material in the detection of high-grade squamous intraepithelial lesion (HSIL). Materials and methods: Patients treated with conization after previous DPT and PB/ECC were analyzed. The findings of the DPT and PB/ECC as well as of the endocervical brush cytology and ECC were compared with the final conus histology. Results: 150 patients were analyzed, and final histology verified 145 cases of HSIL and 3 cancers. The percentage of confirmed HSIL cytology was 97%, while for PB/ECC it was 79% with 30/145 false negative results. The correlation between Pap test and PB/ECC showed that the diagnostic accuracy of DPT is significantly higher (p < 0.0001). Endocervical brush cytology confirmed HSIL+ in the endocervical canal in 83% and ECC in 35% of cases (p < 0.0001). Conclusion: The DPT on three slides enables better detection of HSIL compared to PB/ECC, particularly for lesions localized in the endocervical canal sampled with a cytobrush. A high quality DPT could represent a surrogate for PB/ECC and open the possibility of direct access to therapeutic procedure.

Abstract:
This paper presents the hardware-in-the-loop simulation for dynamic performance test (HILS-DPT) of power electronic equipment replicas using a real-time hybrid simulator (RTHS). The authors developed the procedure of HILS-DPT, and as an actual case example, the results of HILS-DPT of Static VAR Compensator (SVC) replica using RTHS is presented. RTHS is a co-simulation tool that synthesizes real-time simulator (RTS) with transient stability program to perform real-time dynamic simulation of a large power system. As power electronics applications have been increasing, the electric utilities have performed HILS-DPT of the power electronics equipment to validate the performance and investigate interactions. Because inspection tests are limited in their ability to validate its impact on the power system during various contingencies, all power electronics equipment newly installed in the Korean power system should take HILS-DPT using large-scale RTS with replicas since 2018. Although large-scaled RTS offers an accuracy improvement, it requires lots of hardware resources, time, and effort to model and simulate the equipment and power systems. Therefore, the authors performed SVC HILS-DPT using RTHS, and the result of the first practical application of RTHS present feasibility comparing the result of HILS-DPT using large-scale RTS. The authors will discuss the test results and share lessons learned from the industrial experience of HILS-DPT using RTHS.

Abstract:
The Chinese Dynamic Penetration Test (DPT) was used following the 2008 Wenchuan earthquake to measure penetration resistances of gravels that liquefied and nearby gravels that did not. The test has many advantages, including simplicity, continuous data acquisition, and robust equipment that is easily transported by light vehicles and low cost. A probability formula, developed from logistic procedures, was proposed using the 47 compiled DPT data. The DPT could be a viable test for measurement of penetration resistance of gravels in other parts of the world beyond China.

Abstract:
Context.—Lupus anticoagulant (LA) is a heterogeneous group of antiphospholipid antibodies. Among others, diluted prothrombin time (dPT) is a sensitive screening test for LA; however, the interpretation of LA tests is difficult in patients treated with anticoagulants. The effect of different types of anticoagulants on the result of LA tests, particularly on dPT, has not been studied extensively. Objective.—To determine whether the direct thrombin inhibitors lepirudin and argatroban and the predominantly factor Xa inhibitors enoxaparin, danaparoid, and fondaparinux could interfere with LA screening based on dPT. Design.—Each drug was added to normal and LA-positive plasmas in clinically relevant concentrations. Each sample was tested for dPT. Samples with factor Xa inhibitors were investigated before and after addition of heparinase. Mixing and confirmatory tests for LA were not performed. Results.—In the presence of lepirudin or argatroban, dPT increased notably and the dPT ratio exceeded the cutoff value even at subtherapeutic concentrations resulting in false positivity. With increasing factor Xa inhibitor concentrations, a linear increase of dPT ratios and false-positive results were also demonstrated. Although heparinase could almost completely neutralize the anti-Xa effect of all investigated factor Xa inhibitors, dPT ratio returned to the basal level only in case of enoxaparin. Conclusions.—Here we provide evidence that both the direct thrombin and indirect factor Xa inhibitors influence dPT assay for LA, causing false positivity. This should be considered when interpreting LA results during anticoagulant therapy. However, dPT seems to be a reliable test for LA screening under enoxaparin therapy after neutralization by heparinase.

The object of the thesis is soils that occur within the territory of Lithuania and may be used as basis for building foundations. The thesis studies the interpretation of the results of Dynamic Penetration Test (DPT) and Cone Penetration Test (CPT) of soils, reliability of direct (number of blows (Nx)) and de-rivative (dynamic point resistance (qd)) DPT parameters, analyses the result influencing factors and interrelation between DPT and CPT parameters. The data analysis has been performed by means of mathematical methods of statistics, also using analytical and empirical solutions. Having examined calculation data it was determined that the indirect parameter of Dy-namic Penetration Test – dynamic point resistance (qd) should not be used due to calculation de-faults and replaced with the direct parameter – number of blows (Nx). The analysis of DPT re-sults influencing factors shows that the lateral overburden pressure together with friction of rods are those with the greatest impact on penetration data. Within the scope of the work, it has re-vealed that the number of blows (Nx) and static cone resistance (qc) are closely correlated and it depends on the grain size distribution of soil, geotechnical properties and depth of occurrence.

Abstract:
The development of a reliable, and cost-effective in-situ method for characterizing the liquefaction potential of gravelly soils is a considerable challenge for engineers and researchers. The ability to accurately characterize the liquefaction potential of gravelly soils is an important consideration at port facilities and dams for example. The Dynamic Penetration Test (DPT) provides a reliable and cost-effective method for evaluating the liquefaction resistance of gravelly soils. Probabilistic liquefaction triggering curves based on DPT field data have been developed from data collected at 47 sites in China. However, using the DPT-based liquefaction curves for locations outside of the Chengdu plain in China where the data for the triggering curves were gathered may yield unreliable results. To improve the reliability of the DPT-based liquefaction triggering curves additional DPT field data form outside of the Chengdu plain is required. In total seven new non-liquefaction DPT case histories are presented in this report. Two of the case histories are based on DPT field data from Valdez, Alaska. The remaining five case histories were developed from DPT field data from L'Aquila, Italy. When plotted on the liquefaction triggering curves based only on the DPT data obtained in the Chengdu plain three of the seven data points plot in a position that indicates a considerable possibility of liquefaction despite these case histories being from locations where liquefaction did not occur. Roy (2021) developed new DPT-based liquefaction triggering curves with these seven new non-liquefaction case histories, DPT filed data from other sites around the world, and the DPT field data from the Chengdu plain. The three data points from the new case histories presented in this report that had a considerable probability of liquefaction when plotted on the curve developed only with the data from the Chengdu plain had a significantly lower probability of liquefaction when plotted on the new DPT-based liquefaction triggering curves. One of the data points from Valdez, Alaska decreased from a probability of liquefaction of around 50% to a probability of liquefaction of less than 30% when plotted on the new DPT-based liquefaction triggering curves. The reliability of DPT-based liquefaction triggering curves will continue to increase as the amount of available DPT data increases.

Abstract:
Compte tenu de la complexité des circuits intégrés de nos jours et des nœuds technologiques qui ne cessent pas de diminuer, être au rendez-vous avec les demandes de design, test et fabrication des dispositifs de haute qualité est devenu un des plus grands défis. Avoir des circuits intégrés de plus en plus performants devrait être atteint tout en respectant les contraintes de basse consommation, de niveaux de fiabilité demandés, de taux de défauts acceptables ainsi que du bas coût. Avec ce fascinant progrès de l’industrie des semi-conducteurs, les processus de fabrication sont devenus de plus en plus difficile à contrôler, ce qui rend les puces électroniques de nos jours plus disposés aux défauts physiques. Le test était et restera l’unique solution pour lutter contre l’occurrence des défauts de fabrication ; même il est devenu un facteur prédominant dans le coût totale de fabrication des circuits intégrés. Même si des solutions de test, qui existent déjà, étaient capables de satisfaire ce fameux compromis coût-qualité ces dernières années, il arrive d’observer encore des mécanismes de défauts malheureusement incontrôlables. Certains sont intrinsèquement reliés au processus de fabrication en lui-même. D’autres reviennent sans doute aux pratiques de test et surtout quand on analyse le taux de défauts détectés et le niveau de fiabilité atteint.L’objectif principal de cette thèse est d’implémenter des stratégies de test robustes et efficaces qui répondent aux lacunes des techniques de tests classiques et qui proposent des modèles de fautes plus réalistes et répondent au mieux aux attentes des fournisseurs. Dans l’objectif d’améliorer l’efficacité de test en termes de coût, capacité de couverture de faute, nous présentons divers contributions significatives qui touchent différents domaines entre-autres le test sur le terrain, les tests à hautes fréquences sous contraintes de puissance et finalement le test des chaines de scan.La partie majeure de cette thèse était consacrée pour le développement de nouvelles techniques de tests fonctionnels ciblant les systèmes à processeurs.Les méthodologies appliquées couvrent les problèmes de test sur terrain aussi bien que les problèmes de test de fabrication. Dans le premier cas, la techniques adoptée consiste à fusionner et compacter un ensemble initial de programmes fonctionnels afin d’atteindre une couverture de faute satisfaisante tout en respectant les contraintes du test sur terrain (temps de test réduit et ressource mémoire limitée). Cependant dans le deuxième cas, comme nous avons assez d’informations sur la structure du design, nous proposons un nouveau protocole de test qui va exploiter l’architecture de test existante. Dans ce contexte, nous avons validé et confirmé la relation complémentaire qui joint le test fonctionnel avec le test structurel. D’autres part, cette prometteuse approche assure un test qui respecte les limites de la consommation fonctionnelle et donc une fiabilité meilleure.La dernière contribution de cette thèse accorde toute l’attention à l’amélioration de test de la structure DFT « Design For Test » la plus utilisée qui est la chaîne de scan. Nous présentons dans cette contribution une approche de test qui cible les défauts physiques au sein de la cellule en elle-même.Cette approche représente une couverture de défauts meilleure et une longueur de test plus réduit si nous la comparons avec l’ATPG classique ciblant les mêmes défauts « Intra-cell defect ATPG ».Comme résultat majeur de cette efficace solution de test, nous avons observé une amélioration de 7.22% de couverture de défaut accompagné d’une réduction de 33.5% du temps de test en comparaison avec la couverture et le temps du test atteints par le « Cell-awer ATPG »
In light of the aggressive scaling and increasing complexity of digital circuits, meeting the demands for designing, testing and fabricating high quality devices is extremely challenging.Higher performance of integrated circuits needs to be achieved while respecting the constraints of low power consumption, required reliability levels, acceptable defect rates and low cost. With these advances in the SC industry, the manufacturing process are becoming more and more difficult to control, making chips more prone to defects.Test was and still is the unique solution to cover manufacturing defects; it is becoming a dominant factor in overall manufacturing cost.Even if existing test solutions were able to satisfy the cost-reliability trade-off in the last decade, there are still uncontrolled failure mechanisms. Some of them are intrinsically related to the manufacturing process and some others belong to the test practices especially when we consider the amount of detected defects and achieved reliability.The main goal of this thesis is to implement robust and effective test strategies to complement the existing test techniques and cope with the issues of test practices and fault models. With the objective to further improve the test efficiency in terms of cost and fault coverage capability, we present significant contributions in the diverse areas of in-field test, power-aware at-speed test and finally scan-chain testing.A big part of this thesis was devoted to develop new functional test techniques for processor-based systems. The applied methodologies cover both in-field and end-of manufacturing test issues. In the farmer, the implemented test technique is based on merging and compacting an initial functional program set in order to achieve higher fault coverage while reducing the test time and the memory occupation. However in the latter, since we already have the structure information of the design, we propose to develop a new test scheme by exploiting the existing scan chain. In this case we validate the complementary relationship between functional and structural testing while avoiding over as well under-testing issues.The last contribution of this thesis deals with the test improvement of the most used DFT structure that is the scan chain. We present in this contribution an intra-cell aware testing approach showing higher intra-cell defect coverage and lower test length when compared to conventional cell-aware ATPG. As major results of this effective test solution, we show that an intra-cell defect coverage increase of up to 7.22% and test time decrease of up to 33.5 % can be achieved in comparison with cell-aware ATPG

Abstract:

The purpose of this study was to determine the reliability and validity of the Dot Counting Test as a measure of feigned cognitive performance. Archival neuropsychological test data from a “real world” sample of 147 credible and 328 non-credible patients were compared. The Dot Counting Test E-score cutoff of ≥ 17 continued to show excellent specificity (93%). However, sensitivity dropped from approximately 74% documented in 2002 to 51% in the current sample. When the cutoff was lowered to ≥ 15, adequate specificity was maintained (90%) and sensitivity rose to (61%). However, a third of credible patients with borderline IQ failed the test using the Dot Counting Test E-cutoff score, indicating cautious use of the test with individuals who likely have borderline intelligence.

Abstract:
The objective of manufacturing test is to separate the faulty circuits from the good circuits after they have been manufactured. Three problems encompassed by this task will be mentioned here. First, the reduction of the power consumed during test. The behavior of the circuit during test is modified due to scan insertion and other testing techniques. Due to this, the power consumed during test can be abnormally large, up to several times the power consumed during functional mode. This can result in a good circuit to fail the test or to be damaged due to heating. Second, how to modify the design so that it is easily testable. Since not every possible digital circuit can be tested properly it is necessary to modify the design to alter its behavior during test. This modification should not alter the functional behavior of the circuit. An example of this is test point insertion, a technique aimed at reducing test time and decreasing the number of faulty circuits that pass the test. Third, the creation of a test set for a given design that will both properly accomplish the task and require the least amount of time possible to be applied. The precision in separation of faulty circuits from good circuits depends on the application for which the circuit is intended and, if possible, must be maximized. The test application time is should be as low as possible to reduce test cost. This dissertation contributes to the discipline of manufacturing test and will encompass advances in the afore mentioned areas. First, a method to reduce the power consumed during test is proposed. Second, in the design modification area, a new algorithm to compute test points is proposed. Third, in the test set creation area, a new algorithm to reduce test set application time is introduced. The three algorithms are scalable to current industrial design sizes. Experimental results for the three methods show their effectiveness.

Abstract:
Abstract In order to evaluate the hydrogen embrittlement sensitivity of 4130X material, the effect of curvature radius of the high-steel ring on material failure mode and blasting pressure was firstly carried out, and then the hydrogen embrittlement sensitivity index was evaluated for disc samples with different surface roughness. The test results show that when the curvature radius of the high-steel ring is 0.5 mm, 1.5 mm, 2.0 mm, the material is mostly destroyed by shear. When the curvature radius is greater or equal to 4.0 mm, the material will be destroyed in the form of blasting. The blasting strength tested in hydrogen environment of 4130X materials decreases when the surface roughness increase from 0.1 to 4.1 μm. For the HE sensitivity evaluation of 4130X by DPT method, it is recommended that the curvature radius should be greater or equal to 4.0 mm, and the surface roughness between 0.1 and 1.5 μm can meet the DPT requirements.

Abstract:
Earthquakes and related coseismic effects at the surface, such as liquefaction and lateral spreading, can impact humans due to the resulting economic or social disruptions (e.g. slope and foundation failures, flotation of buried structures, etc.). In this respect, the 2020 Petrinja Mw6.4 earthquake (Croatia) provided many examples of liquefaction and lateral spreading, as identified by the post-earthquake field reconnaissance campaigns. The observed liquefaction cases occurred in the alluvial plains of the Kupa, Sava and Glina Rivers or along faults, with ejecta composed of sands and/or gravels of different grain size and mineralogy. The lateral spreading phenomena were observed along river embankments and roads. In this context interest in studying these different features arose, and an international research team from Italy, the United States and Croatia recently performed an intensive geological, geotechnical and geophysical campaign to assess the liquefaction susceptibility at selected sites located throughout the epicentral area (from Glina to Petrinja to Sisak). Innovative in-situ test equipment, such as the dynamic cone penetration test (DPT) for liquefied gravels and the Medusa flat dilatometer test (Medusa DMT) for liquefied sands, were employed in combination with standard in-situ tests,such as the standard penetration test (SPT), the piezocone test (CPTU), and shear wave velocity (Vs) measurements. These techniques were employed to verify their advantages relative to the existing iquefaction triggering charts and to characterize the soil properties of the buried liquefied layers and the non-liquefied crust. This paper presents preliminary results and comparisons at some of the investigated liquefaction sites.

Abstract:
Gravelly soils have liquefied at multiple sites in at least 27 earthquakes over the past 130 years. These gravels typically contain more than 25% sand which lowers the permeability and makes them susceptible to liquefaction. Developing a reliable, cost-effective liquefaction triggering procedure for gravelly soils has been a challenge for geotechnical engineers. Typical SPT- or CPT-based correlations can be affected by large-size gravel particles and can lead to erroneous results. To deal with these problems, we have developed liquefaction triggering curves for gravelly soils based on (1) shear wave velocity (Vs) and (2) a large diameter cone penetrometer. With a cone diameter of 74 mm, the Chinese Dynamic Cone Penetration Test (DPT) is superior to smaller penetrometers and can be economically performed with conventional drilling equipment. Using logistic regression analysis, the DPT has been directly correlated to liquefaction resistance at sites where gravels did and did not liquefy in past earthquakes. Probabilistic liquefaction resistance curves were developed based on 137 data points from 10 different earthquakes in seven countries. Using a similar data set, probabilistic liquefaction triggering curves were also developed based on Vs measurements in gravelly soils. The Vs-based liquefaction triggering curves for gravels shift to the right relative to similar curves based on sands. New magnitude scaling factor (MSF) curves have also been developed specifically for gravel liquefaction which were found to be reasonably consistent with previous curves for sand.

Abstract:
<div class="section abstract"><div class="htmlview paragraph">Synthetic fuels can significantly improve the combustion and emission characteristics of heavy-duty diesel engines toward decarbonizing heavy-duty propulsion systems. This work analyzes the effects of engine operating conditions and synthetic fuel properties on spray, combustion, and emissions (soot, NOx) using a supercharging single-cylinder engine experiment and KIVA-4 code combined with CHEMKIN-II and in-house phenomenological soot model. The blended fuel ratio is fixed at 80% diesel and 20% n-paraffin by volume (hereafter DP). Diesel, DP1 (diesel with n-pentane C5H12), DP2 (diesel with n-hexane C6H14), and DP3 (diesel with n-heptane C7H16) are used in engine-like-condition constant volume chamber (CVC) and engine experiments.</div><div class="htmlview paragraph">Boosted engine experiments (1080 rpm, common-rail injection pressure 160 MPa, multi-pulse injection) are performed using the same DP fuel groups under various main injection timings, pulse-injection intervals, and EGR = 0-40%. Once the 3D-CFD model is validated with the CVC and experimental engine data, in-cylinder combustion and emissions are analyzed. The CVC experiments show that DP2 and DP3 liquid penetrations are shorter than diesel oil. In engine tests, NOx did not change much for all DP fuels for the same engine operating condition. However, shorter-penetrated DP2 and DP3 reduce soot emissions by more than 60% and CO without worsening brake-specific fuel consumption compared to diesel oil. The 3D-CFD results show that n-hexane shifts the penetration of the high-carbon number to the low-carbon fuel. Vapor penetrations are found to be shortened by blending low-volatility fuels with diesel oil. Visualizations of the in-cylinder confirmed a decrease in the amount of soot formation near the wall for DP2 and DP3 fuels. In addition, equivalence ratio – temperature (phi-T) maps of these fuels indicate that at 40% EGR, soot emissions are reduced at lower equivalence ratios than diesel oil.</div></div>

Abstract:
Abstract The European Union is banning the use of Pb in electronic products starting July 1st, 2006. Printed circuit board assemblies or “motherboards” require that planned CPU sockets and BGA chipsets use lead-free solder ball compositions at the second level interconnections (SLI) to attach to a printed circuit board (PCB) and survive various assembly and reliability test conditions for end-use deployment. Intel is pro-actively preparing for this anticipated Pb ban, by evaluating a new lead free (LF) solder alloy in the ternary Tin- Silver-Copper (Sn4.0Ag0.5Cu) system and developing higher temperature board assembly processes. This will be pursued with a focus on achieving the lowest process temperature required to avoid deleterious higher temperature effects and still achieve a metallurgically compatible solder joint. One primary factor is the elevated peak reflow temperature required for surface mount technology (SMT) LF assembly, which is approximately 250 °C compared to present eutectic tin/lead (Sn37Pb) reflow temperatures of around 220 °C. In addition, extended SMT time-above-liquidus (TAL) and subsequent cooling rates are also a concern not only for the critical BGA chipsets and CPU BGA sockets but to other components similarly attached to the same PCB substrate. PCBs used were conventional FR-4 substrates with organic solder preservative on the copper pads and mechanical daisychanged FCBGA components with direct immersion gold surface finish on their copper pads. However, a materials analysis method and approach is also required to characterize and evaluate the effect of low peak temperature LF SMT processing on the PBA SLI to identify the absolute limits or “cliffs” and determine if the minimum processing temperature and TAL could be further lowered. The SLI system is characterized using various microanalytical techniques, such as, conventional optical microscopy, scanning electron microscopy, energy dispersive spectroscopy and microhardness testing. In addition, the SLI is further characterized using macroanalytical techniques such as dye penetrant testing (DPT) with controlled tensile testing for mechanical strength in addition to disbond and crack area mapping to complete the analysis.

Abstract:
Colleges, universities, and secondary schools around the world are using the Duolingo English Test (DET) as a new way to assess English language proficiency. The DET offers many advantages to admissions offices and applicants: on-demand accessibility, low cost, remote test proctoring, and rapid score reporting, as well as an integrated video interview and writing sample. The DET also looks and functions differently from other proficiency tests, which raises an obvious question. If DET item types and administration differ from those used on other large scale tests like the TOEFL® or IELTS®, can DET test scores be used in the same way as the scores from those instruments?

Abstract:
We describe a two-year study of the relationship between the Duolingo English Test (DET) and the academic English ability of non-native international students at DePauw University. We found DET scores to be significantly correlated with on-campus faculty assessments of English ability for incoming international students (r = 0.62*** for written ability and r = 0.49*** for oral comprehensibility). We also found that DET scores significantly predict the faculty’s decisions to place certain students into academic English support classes. Furthermore, the DET was more strongly associated with faculty assessments than TOEFL® iBT scores. These results were consistent across both cohorts of first-year students studied (2014 and 2015 incoming classes).
