Streszczenie:

This research aims to evaluate the Value-added Tax (VAT) collection on trading through the electronic system (TTES) from the TTES VAT Collector’s perception, based on "The Four Maxims" tax collection principle. This research uses a qualitative research method with a case study approach. Data was collected using interview techniques with eight respondents from TTES VAT Collectors. The results showed that TTES VAT collection in Indonesia has fulfilled the equality, convenience and efficiency principles based on "The Four Maxims". However, the collection of TTES VAT in Indonesia has failed to meet the criterion of certainty, owing to uncertainties in the definition, the legal status of the collector, the method for calculating the tax basis, tax procedures, and the enforcement of fines.

Streszczenie:

The article investigates the impact of various funding sources on Technology Transfer Entities (TTEs), including government support, private sector investments, grants, and European funds. It emphasizes the crucial role these financial mechanisms play in enabling TTEs to bridge the gap between academic research and commercial application. By analyzing the influence of government funding, the significance of licensing and patent revenues, and the benefits of private and European investments, the article demonstrates how these resources assist TTEs in achieving financial stability, fostering innovation commercialization, and navigating the market. It also highlights the importance of aligning TTEs' goals with broader societal and economic objectives. Through case studies, the research illustrates the essential need for a diverse funding strategy and effective management for TTEs to optimize their contribution to the technological innovation ecosystem, economic growth, and societal well-being

This study estimates the impact of major road supply on individual travel time expenditures (TTEs) using data that cover 30-year variations in transportation infrastructure and travel behavior. The impacts of the supply of road and rail infrastructure are estimated with a data set that combines records of large-scale household travel surveys in the Tokyo metropolitan area conducted in 1978, 1988, 1998, and 2008. Linear and Tobit models of individual TTEs are estimated by following the behavior of birth cohorts over the 30-year period. The models incorporate the changes in transportation infrastructure, measured as lane kilometers of two levels of major road stock and vehicle kilometers of urban rail service. The results show significant negative effects of lane kilometers for higher-level and lower-level major roads on the TTEs for all travel purposes and for commuting, after controlling for socioeconomic backgrounds and generations of individuals. This study discusses that, in Tokyo, the estimated effect is more likely to reflect the effect of a major road network per se on individual TTEs than the (indirect) effect of major road supply on individual TTEs working through land development activities (i.e., induced car travel demand). For example, the caveat is that actual road investment decisions still need to consider the induced component of road traffic in addition to the (direct) effect that is estimated in this study.

This paper evaluates the financial performance of technology transfer entities (TTEs) by analyzing both economic and financial models. Traditional financial models, such as Discounted Cash Flow (DCF) and Capital Asset Pricing Model (CAPM), provide insights into investment viability and risk management in TTEs. Economic models, like IS-LM and growth models, help understand the macroeconomic environment's influence on technological innovation. Specific models, such as the linear innovation model and the Triple Helix framework, emphasize the collaboration between academia, industry, and government in fostering innovation. The integration of real options analysis and venture capital methods further supports investment decisions in high-uncertainty technological projects. This approach helps TTEs optimize resource allocation and strategic investments, contributing to sustainable economic growth.

Late diagnosis of critical congenital heart disease (CCHD) is associated with higher levels of morbidity and mortality in neonates. Nearly all states have passed laws mandating universal pulse oximetry screening (POxS) of newborns to improve early detection rates of CCHD. We performed a retrospective chart review of all transthoracic echocardiograms (TTEs) interpreted by our institution on patients between 0 and 30 days of life in the years 2010 (prior to POxS) and 2015 (after POxS). Between 2010 and 2015, the number of neonatal TTEs interpreted by our institution decreased by 18.2%. In 2015, there were 46 neonates diagnosed with CCHD with a 78% prenatal detection rate. There was only one case of a true-positive POxS. Our study demonstrated that the initiation of POxS coincided with a significant decrease in neonatal TTEs, suggesting universal POxS may impart reassurance to primary providers leading to a decrease in TTE utilization.

Streszczenie:

The development of dry, ultra-conformable and unperceivable temporary tattoo electrodes (TTEs), based on the ink-jet printing of poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) on top of commercially available temporary tattoo paper, has gained increasing attention as a new and promising technology for electrophysiological recordings on skin. In this work, we present a TTEs epidermal sensor for real time monitoring of respiration through transthoracic impedance measurements, exploiting a new design, based on the application of soft screen printed Ag ink and magnetic interlink, that guarantees a repositionable, long-term stable and robust interconnection of TTEs with external “docking” devices. The efficiency of the TTE and the proposed interconnection strategy under stretching (up to 10%) and over time (up to 96 h) has been verified on a dedicated experimental setup and on humans, fulfilling the proposed specific application of transthoracic impedance measurements. The proposed approach makes this technology suitable for large-scale production and suitable not only for the specific use case presented, but also for real time monitoring of different bio-electric signals, as demonstrated through specific proof of concept demonstrators.

Background: The use of T tube enterostomy (TTES) as an alternative option for stoma in neonatal emergency is known long time ago.Methods: We introduced T-tube ileostomy as technical innovation in our institution as a way of treatment for intestinal perforation in low birth weight premature neonates.Results: In this study 14 neonates underwent TTES procedures at university-based pediatric surgery and neonatology department. 11 (78.6%) patients treated with TTES, discharged home. Three babies (22.4%) died in postoperative course. One of them developed recurrent severe fulminant NEC ileostomy was created and kept on TPN but died after 2 weeks due to septicaemia. The two others were dysmorphic with metabolic diseases.Conclusions: T tube is effective in selected cases of necrotizing enterocolitis (NEC) because of its simplicity in application and removal. But it could not replace the formal stoma in general, its advantages are saving one more time exposure to surgery in those risky patients, Author recommend the use it in cases of post NEC intestinal perforation and extreme low birth weight neonates.

e16109 Background: Cancer patients are at increased risk for thromboembolic events (TTEs), and those receiving chemotherapy are at even greater risk. Clinical experience and the literature have suggested that men receiving cisplatin-based chemotherapy for metastatic germ cell tumors are at particularly high risk. As TTEs can be fatal and treatment is curative, the stakes are high. Despite this, prophylactic anticoagulation (PA) is not routinely used. Methods: All men treated with cisplatin-based chemotherapy for metastatic germ cell cancer at the London Regional Cancer Program from January 1978 to December 2007 were identified from electronic databases. Data including type and timing of TTEs were extracted by retrospective chart review. Multivariable analyses were used to identify predictors of TTEs. Results: 196 eligible patients were identified with median age 31 years (range, 15–75). No patients received PA. Thirty-two TTEs were identified in 29 patients for an overall incidence of 14.8% (95% CI, 9.8–19.8%). The majority of events were deep venous thromboses, and five patients died due to TTE or its complications. Sixteen of the patients with TTE (55.2%) were diagnosed while on treatment (defined as TTE within 6 months of chemotherapy initiation); 8 (27.6%) had their TTE prior to, and 5 (17.2%) after this time period. Age greater than 30 years (OR = 3.02; 95% CI, 1.10–8.33; p = 0.033) and elevated LDH (OR = 1.93; 95% CI, 1.07–3.48; p = 0.029) were independently associated with an increased risk of TTE. If both adverse risk factors were present, the risk of TTE on treatment was 21.7% (95% CI, 9.8–33.7%). If neither were present, the negative predictive value was 97% (95% CI, 92–100%). Conclusions: The overall TTE incidence rate of 14.8% is consistent with prior reports (8.4–19%). The risk of TTE appears greatest during chemotherapy and shortly thereafter, and nearly one in 10 patients in this group had a TTE. These data support the concept of PA for selected patients starting chemotherapy for metastatic germ cell cancer. However, the efficacy of PA and risk of hemorrhage in this group is unknown. In this cohort, patients under 30 with normal LDH were at very low risk for TTE. Confirmation of these findings to help guide the study and optimal use of PA should be pursued. No significant financial relationships to disclose.

Streszczenie:

The goal of this study was to investigate the effects of photobiomodulation therapy (PBMT) on performance, oxygen uptake (VO2) kinetics, and lower limb muscle oxygenation during three successive time-to-exhaustions (TTEs) in cyclists. This was a double-blind, randomized, crossover, placebo-controlled trial study. Sixteen cyclists (~23 years) with a cycling training volume of ~460 km/week volunteered for this study. In the first session, cyclists performed a maximal incremental test to determine maximal oxygen uptake and maximal power output (POMAX). In the following sessions, cyclists performed three consecutive TTEs at POMAX. Before each test, PBMT (135 J/thigh) or a placebo (PLA) was applied to both thighs. VO2 amplitude, O2 deficit, time delay, oxyhemoglobin (O2Hb), deoxyhemoglobin (HHb), and total hemoglobin (tHb) were measured during tests on the right vastus lateralis. The PBMT applied before three successive TTE increased performance of the first and second TTE (~10–12%) tests, speed of VO2 and HHb kinetics during the first test, and increased peripheral muscle oxygenation (increase in HHb and tHb) in the first and second exhaustion tests. However, the PBMT effects were attenuated in the third TTE, as performance and all the other outcomes were similar to the ones from the PLA intervention. In summary, PBMT application increased the first and second successive TTEs, speed of VO2, and muscle oxygenation.

Streszczenie:

Le stockage d'énergie est essentiel à la transition énergétique car il permet de découpler la production de l'énergie de sa consommation. Le stockage de chaleur thermocline en eau, utilisé dans les réseaux de chaleur à moyenne ou basse température, repose sur la stratification thermique dans une cuve. Les performances de ce type de stockage sont fortement liées à la bonne stratification du fluide qui peut être perturbée par l'injection et le soutirage du liquide, des aspects peu explorés dans la littérature.L'objectif de cette thèse est de modéliser un tel stockage de manière fiable pour analyser la distribution du fluide. En effet, le but est de mieux appréhender les phénomènes physiques gouvernant la thermocline pendant les cycles de fonctionnement et d'accroître ses performances énergétiques par un design ou un pilotage amélioré. Pour ce faire, des études numériques utilisant la CFD (Computational Fluid Dynamics) ont été réalisées et comparées à des données expérimentales disponibles dans la littérature et obtenues via une nouvelle section d'essais.Dans un premier temps, un modèle CFD a été développé basé sur un cas expérimental existant de la littérature. Dans un stockage thermocline en eau, il y a bien souvent coexistence entre une région laminaire dans la cuve et turbulente à proximité des distributeurs. Cette coexistence est un enjeu majeur de la modélisation car la plupart des modèles de turbulence ne sont pas capables de représenter fiablement la transition d'un écoulement turbulent vers laminaire. Pour ces travaux, une méthode statistique RANS (Reynolds Average Numerical Simulation) est adoptée et le modèle k-omega-SST est sélectionnée car il permet de représenter les écoulements en proche paroi. Concernant la flottabilité, il existe deux méthodes pour considérer ses effets : utiliser une masse volumique variable dans l'ensemble des équations, ou constante sauf dans le terme de flottabilité . Cette dernière est connue sous le nom de l'approximation de Boussinesq mais n'est valable que sur une faible gamme de ΔT. La précision de l'approximation de Boussinesq a été remise en question et une approche au second ordre de ce modèle est employée. Celle-ci permet d'obtenir le même terme de flottabilité qu'un modèle à masse volumique variable mais avec un temps de calcul réduit de moitié. La comparaison avec des données expérimentales a permis de souligner l'impact de l'état initial en température (stockage stratifié ou homogène). Une étude exploratoire de l'impact d'une injection progressive selon une rampe en débit a montré son impact sur la réduction de l'épaisseur de la thermocline au moment de sa création.Dans une démarche de validation du modèle et de vérification des observations numériques, un nouveau dispositif expérimental a été conçu. Celui-ci mesure la température grâce à 300 thermocouples disposés dans la cuve et permet un contrôle précis des conditions opératoires. Des études en phase statiques pour évaluer les pertes thermiques ont été réalisées. Des études dynamiques ont permis de faire varier les paramètres opératoires pertinents : la vitesse de propagation axiale, l'écart de température, le dispositif de soutirage ou encore l'injection progressive. Pour ce système, les résultats montrent qu'il est possible d'obtenir une stratification à forte vitesse (> 2 mm/s) tant que le ΔT est suffisamment élevé.Enfin, l'écoulement dans la section d'essais a été étudié numériquement avec un modèle CFD actualisé. Les champs de variables ont montré que les résultats numériques et expérimentaux sont cohérents, en particulier lors de la formation de la thermocline. Toutefois, un excès de diffusion lors de la propagation du gradient thermique à faible débit est notable. Pour tous les essais réalisés les écarts expérimentaux et numériques ont été quantifiés: à l'exception des conditions critiques, l'écart sur l'épaisseur de thermocline est de ±50% et se situe entre 0 et -10% pour le taux de restitution
Energy storage is essential to the energy transition as it allows decoupling energy production from its consumption. Water-based thermocline heat storage, used in medium or low-temperature heating networks, relies on thermal stratification in a tank. The performance of this type of storage is strongly linked to the proper stratification of the fluid, which can be disrupted by the injection and extraction of the liquid, aspects that are scarcely explored in the literature.The objective of this thesis is to reliably model such storage to analyze the fluid distribution. The aim is to better understand the physical phenomena governing the thermocline during operating cycles and to enhance its energy performance through improved design or control. To achieve this, numerical studies using CFD (Computational Fluid Dynamics) were conducted and compared with experimental data available in the literature and obtained via a new experimental setup.Initially, a CFD model was developed based on an existing experimental case from the literature. In water thermocline storage, there is often coexistence between a laminar region in the tank and a turbulent region near the distributors. This coexistence is a major challenge in modeling because most turbulence models cannot reliably represent the transition from turbulent to laminar flow. For this work, a RANS (Reynolds Average Numerical Simulation) statistical method is adopted, and the k-omega-SST model is selected as it can represent near-wall flows. Regarding buoyancy, there are two methods to consider its effects: using a variable density in all equations or a constant density except in the buoyancy term. The latter is known as the Boussinesq approximation but is only valid over a narrow range of ΔT. The accuracy of the Boussinesq approximation has been questioned, and a second-order approach of this model is employed. This allows obtaining the same buoyancy term as a variable density model but with a calculation time reduced by half. Comparison with experimental data highlighted the impact of the initial temperature state (stratified or homogeneous storage). An exploratory study of the impact of progressive injection according to a flow ramp showed its effect on reducing the thermocline thickness at the time of its creation.As part of the model validation and verification of numerical observations, a new experimental setup was designed. It measures the temperature using 300 thermocouples placed in the tank and allows precise control of operating conditions. Static phase studies to evaluate thermal losses were conducted. Dynamic studies allowed varying relevant operating parameters: axial propagation speed, temperature difference, extraction device, and progressive injection. For this system, the results show that it is possible to obtain stratification at high speed (> 2 mm/s) as long as the ΔT is sufficiently high.Finally, the flow in the test section was numerically studied with an updated CFD model. The variable fields showed that the numerical and experimental results are consistent, especially during the formation of the thermocline. However, excessive diffusion during the propagation of the thermal gradient at low flow is notable. For all the tests carried out, the experimental and numerical discrepancies were quantified: except for critical conditions, the discrepancy in thermocline thickness is ±50% and ranges from 0 to -10% for the restitution rate

Text-till-talsynteser (eng. Text-to-speech, TTS), med andra ord digitalt skapade röster, har blivit en naturlig del av våra dagliga liv. Vi hör dem i kollektivtrafiken, när vi interagerar med digitala assistenter och när människor som saknar en egen röst använder dem för att kommunicera. Dessa artificiella röster har, precis som riktiga röster, olika egenskaper som påverkar hur de låter och uppfattas. Det är därför intressant att förstå vilka TTS-synteser som användare föredrar i olika sammanhang. I denna studie undersöktes huruvida det finns en preferens för olika kön hos instruerande TTS-synteser. I studien fick 46 deltagare spela ett spel där målet var att fullfölja ett antal upplästa instruktioner genom olika knapptryck på skärmen. Spelet var uppdelat i två omgångar, där instruktören i ena omgången var en TTS-syntes med en manlig röst och i den andra en kvinnlig. Vilken TTS-syntes som började och ordning av instruktioner slumpades för deltagarna. Efter spelad omgång svarade deltagarna på en enkät om upplevda röstegenskaper hos instruktören. När sista omgången fullföljts besvarades även en avslutande enkät där det bland annat frågades vilken av TTS-synteserna de föredrog, följt av en kvalitativ fråga där de fick motivera sitt svar. Svaren analyserades sedan genom ett statistiskt test och en kvalitativ analys. Studien kunde ej påvisa någon preferens för kön hos instruerande TTS-synteser. Istället visade resultatet att testpersonerna har individuella preferenser och åsikter om rösterna, även om det verkade finnas viss konsensus om somliga upplevda röstegenskaper hos TTS-synteser.
Text-to-speech synthesis (TTS), in other words digitally created voices, has become a natural part of our daily lives. We hear them in public transport, when we interact with digital assistants and when people who do not have their own voice use them to communicate. These artificial voices, just like real voices, have different properties that affect how they sound and are perceived. It is thereby interesting to understand which TTS-synthesis users prefer in different contexts. This study examined whether there is a preference for different genders in instructional TTS-synthesis. In the study, 46 participants played a game where the goal was to complete a number of read out loud instructions through various key presses on the screen. The game was divided into two rounds, where the instructor in one round was a TTS-synthesis with a male voice and female in the other one. Which TTS-synthesis started and the order of instructions was randomized for each participant. Upon completing the round, the participants answered a questionnaire about perceived voice characteristics of the instructor. When the final round was completed, a final questionnaire was also answered in which, among other things, it was asked which of the TTS-syntheses the test subjects preferred, followed by a qualitative question in which they were asked to justify their answer. The answers were then analyzed through a statistical test and a qualitative analysis. The study could not demonstrate any gender preference in instructional TTS-synthesis. Instead, the results showed that the test subjects have individual preferences and opinions about the voices, even though there seemed to be some consensus about some of the perceived voice characteristics of the TTS-syntheses.

Streszczenie:

This PhD thesis presents the development of a prosody system for European Portuguese (EP) for text-to-speech (TTS) applications. Basically, TTS systems carry out the automatic utterance of a text and consist in a sequence of several modules. Those modules implement the pre-processing of the text input, the phonetic transcription and the supra-segmental processing that consists in the inclusion of prosodic patterns. The prosody is responsible for a communicative intention and guarantees some naturalness in the uttered speech. The prosodic features consist in the imposition of the timing, characterized by the segmental durations and pauses, the intonation, characterized by the fundamental frequency (F0) curve, and by the intensity curve. The preparatory work that was fundamental for modelling and testing purposes is presented in the beginning. It starts with a preliminary study about the stressed syllable. This study identifies the variation range of F0, duration and intensity features in stressed syllable along contexts. Then the FEUP-IPB EP speech database that was used in following studies is presented. The database is labelled at the levels of the phoneme, word, sentence and F0. The thesis follows on with the presentation of two algorithms to provide the syllabic splitting of the text and of the phoneme sequences. This chapter ends with a proposed set of rules for the automatic phonetic transcription of the most problematic graphemes in EP. The proposed prosody model consists of several sub-models, namely, the duration model to predict the segmental durations and the model to predict the F0 pattern. Two proposals, based in artificial neural networks (ANNs), to predict the segmental durations are presented. The first proposal consists of one ANN carefully selected concerning its architecture and type as well as the set of input features with the objective of minimizing the error between predicted and measured durations. The second proposal, entitled alternative model, is based on same considerations of the first proposal but uses one dedicated ANN for each phoneme, in a total of 44 ANNs. The alternative model, with dedicated ANNs, improved the final performance. A model of insertion and prediction of durations of the pauses is proposed, based on a preliminary study over the FEUP-IPB database. The proposed model to predict the F0 contour is based on the Fujisaki model and consists of two sub-models. One predicts the Phrase Commands’ (PCs) parameters and the other predicts the Accent Commands’ (ACs) parameters. The PCs and the ACs were manually estimated in 101 paragraphs of the database under the criterion of the minimization of the error between estimated and measured F0 contours. The prediction of the PCs is performed in two stages. The first stage is carried out by an algorithm responsible for the insertion of the PCs connected to the text and based on a mathematical model obtained from experimental observations. The second stage of the model predicts the PCs amplitude, Ap, and anticipation, T0a, relatively to the initial position. The anticipation allows the determination of the exact position in the speech signal. The two parameters are predicted with ANNs. A strong connection between ACs and syllables was found in the database. This strong connection justified the adopted methodology of predicting ACs associated with syllables. Therefore, the ACs model consists of one ANN to predict the existence of AC associated with the syllable and other three ANNs to predict the parameter’s amplitude (Aa) and anticipation of the onset (T1a) and offset (T2a) instants. The final perceptual test using the category-judgment method and the MOS scale resulted in a classification of 4.6 for the natural speech, 4.4 for the estimated F0, 4.2 for predicted durations, 3.1 for the predicted F0 and 2.9 for the complete proposed model (duration and F0 models). The MOS for the complete model is at the ‘Fair’ level.

The purpose of this study was to determine if appraisers using the TTAS in Texas perceived themselves as being objective in the evaluation process. The population for this study was 213 appraisers, both elementary and secondary, chosen randomly from four educational service areas in four regions of Texas. Data were obtained from a 25-item questionnaire mailed to the appraisers. The organization of this study includes a statement of the problem, the research questions, a review of the literature, the methods and procedures used to collect the data, the analysis of the data, and a summary of the findings, conclusions, implications, and recommendations for additional research. Data from the 213 returned questionnaires were treated with the chi-square test of independence. The analysis of data revealed the following: 1. Regardless of the level, elementary or secondary, of the administrator, the majority of respondents held the same views. 2. Regardless of the region of Texas from which the respondents came, the majority of respondents held the same views. 3. Regardless of the number of years of experience of the appraisers, the majority of respondents held the same views. 4. The majority of respondents felt they are objective in their use of the TTAS. The implications are that the TTAS instrument is being used as was its intention, and that the appraisers feel comfortable in the use of the TTAS. Since the TTAS is effective as seen through a majority of respondents, it may be used in future revisions of the current instrument or by other districts as a model by which to begin construction of their own appraisal instruments.

Title: The news betrayal from TT – A quantitative content analysis of TT’s news reporting from the north In the year of 2013 TT-nyhetsbyrån closed down their three local editorial offices in north Sweden with a promise that the news coverage of Norrland would remain the same. In this study we aim to examine if, and how, the journalistic content has changed due to their centralization. Based on theories of media and democracy, the commercialization of journalism and news evaluation, this study investigates different aspects of TT’s journalistic output such as news outlets, news topic, democratic value dimensions, framing, original reporting and sourcing. The material of examination consists of a total of 199 articles which derive from Luleå, Umeå and Sundsvall. Further the material is spread out over two periods of time. More particularly five years before, and five years after the close down. We have employed a so-called synthetic week during both time intervals, meaning that you randomly select Monday one week, Tuesday the following week, and so forth. The result of the quantitative study showed that TT’s news reporting about the municipalities has decreased in all the aspects that have been investigated. The analysis of the result, together with previous research and chosen theories, indicates that TT seems to have become more commercialized and audience-oriented, which may have affected how news is valued. From a democratic perspective it is problematic. As the largest news agency TT plays an important role in Swedish journalism, not least when editorial offices around the country reduce their own news coverage.

Den här uppsatsen har undersökt hur nyhetsbyrån TT rapporterat om flyktingar under två flyktingsituationer, åren 1992 och 2015. De frågeställningar som ska besvaras är: Finns det skillnader mellan hur TT 1992 skrev om flyktingar från f.d. Jugoslavien, och hur TT skriver om flyktingar 2015? Några delfrågor ska också besvaras: I vilka nyhetshändelser figurerar flyktingar och asylsökande? Får flyktingar eller asylsökande en talan i texterna? Är flyktingar eller asylsökande mer frekventa i positiva eller i negativa nyheter? Dessa frågeställningar har besvarats med hjälp av teorin om diskursiv diskriminering. Metoden som använts har varit en kvantitativ innehållsanalys, där urvalet var 130 st artiklar från 1992, och 203 st artiklar från 2015. Man kan se att TT:s medierapportering om flyktingar och asylsökande har varit skev och ojämn 1992, och fortsätter vara det 2015, i form av vem som får tala och vad själva nyheten handlar om. Man kan även se att medierapporteringen från 1992 och 2015 inte skiljer sig från varandra särskilt mycket, det finns dock skillnader. Nyhetshändelserna har skiftat fokus från brott mot flyktingar till flyktingpolitik. Flyktingar och asylsökande var frekventa subjekt i nyhetstexterna. Nyheterna som flyktingar eller asylsökande medverkar i är till stor del negativa, dock så har neutrala nyheter blivit mer vanliga.

This paper reports on one of the main problem-triggers in film dialogue synchronization for dubbing: conversational markers (CMs). The synchronized film scripts (TT2s) from the TRACEci corpus of English-Spanish cinema scripts, ready to be delivered by dubbing actors, are compared with their draft translations (TT1s) and with non-translated Spanish data from the guiones subcorpus of CORPES XXI. Results confirm that the number of CMs has been reduced in the TT2s in favor of synchronization and that certain CMs are indicators of English-Spanish statistical dubbese (overuse), causing unwanted redundancy. The analysis benefits from corpus data and is intended to help both students and professionals to improve the acceptability of their translations.

This paper focuses on efficient automatic recognition algorithms for turning features. As with other domains, recognition of interacting features is a difficult issue, because feature interaction removes faces and alters the topology of the existing turned features. This paper presents a method for efficiently recognizing both isolated (without interaction with other features) and interacting rotational features from geometrical CAD model of mill/turn parts. Additionally, the method recognizes Transient Turned Features (TTFs) that are defined as maximal axisymmetric material volumes from a non-turning feature that can be removed by turning. A TTS may not share any faces with the finished part. First, the rotational faces on a solid model are explored to extract isolated rotational features and some of the interacting ones. Then portions of the 3D model where no rotational faces can be used to recognize turning features are cut out and processed by a novel algorithm for finding their transient turning features.

Abstract Low oil prices, coupled with operational challenges in offshore environment due to COVID-19 restrictions, have driven oil and gas operators to implement low-cost technological solutions to optimize fields’ production. For mature oil fields in offshore East Malaysia, sand production has become one of the onerous challenges that requires this approach. Sand production is known to adversely affect the well deliverability and it also contributes to safety concerns due to surface flowline leak and equipment failure. Hence, it is of upmost importance for operators to address the sand production downhole. To achieve this, through-tubing sand screens (TTSS) installation is opted due to its ease of installation and low-cost slickline operation. Although there have been many TTSS installations to date, there is still limited understanding of the factors that affect TTSS lifespan, and this has led to frequent TTSS changeout. Based on the operator's experience, TTSS lifespan can vary significantly across different wells ranging from just a few days to years of production. To improve the understanding of TTSS performance with the aim to increase TTSS longevity, a comprehensive study on potential contributing factors has been conducted by analyzing the past TTSS installations. Over the years, there were more than 75 TTSS installations performed in oil fields offshore East Malaysia. Lookback analysis was conducted to evaluate the effectiveness of TTSS as remedial downhole sand control and investigate the factors affecting TTSS performance such as TTSS type, well production rates, TTSS deployment method, installation depth relative to perforation interval and well interruption frequency. Several criteria identified as the key performance indicators have been investigated to evaluate the performance of each TTSS installation, including the well flowing parameters, production uptime and sand production trend. Thorough study across different TTSS installations has concluded that TTSS lifespan varies according to well properties and well operating parameters. This paper presents best practices and lessons learnt from past installations to predict and improve the mean time between failures (MTBF) for TTSS. Case studies for several wells have been scrutinized to highlight the learnings for further enhancement of TTSS lifespan. Additionally, recommendations for further research and development of erosion resistant TTSS technology are also discussed.

Abstract Through Tubing Sand Screen (TTSS) is routinely used as a remedial sand control solution by the Operator to mitigate sand production in offshore wells located in East Malaysia. A smaller outer diameter (OD) wire-wrap or premium mesh screen is retrofitted inside or set at the end of an existing tubing to filter sand coming from failed primary sand control zone or when there is no sand control installed. The solution has been adopted extensively to mitigate sand production from existing wells as a low-cost application with relatively simpler installation and retrieval operation via slickline, consequently allows for fast reactivation of sand producing wells. Given the large number of installations carried out by the Operator yearly, and most of them recurring in nature, a study is conducted on the past TTSS installations to understand the performance and develop a workflow for design and operation with the aim of improving future installations. This study is done by analyzing past TTSS installations and the associated production performance including sand production parameter i.e. sand count. Parameters such as screen type, length, opening size and installation depth are studied to evaluate the impact to the production performance and the screen service life. Wells with premature TTSS failure are selected for detailed teardown study, whereby the retrieved TTSS joints are sent to workshop to be cut and analyzed for failure mechanisms such as erosion and plugging. Outcome of the study includes a workflow that addresses the main design and operation consideration for TTSS installation capturing the best practices of past installations. Additionally, the study is used to develop strategy for TTSS installations including the required changeout frequency based on the lifespan and inventory management. The paper describes a study on the TTSS performance analysis including selected case studies and teardown analysis. Also, workflow on TTSS design, selection and installation will be discussed.

Abstract This paper delves into the operational hurdles encountered during coil tubing operations within a specific field in Sarawak, Malaysia. Focused primarily on the sand clean-out process and the challenge of retrieving a lengthy Through-Tubing Sand Screen (TTSS), this paper presents practical solution through the utilization of the coil tubing deployment method. This paper comprehensively outlines the operational techniques used by the project team during the coil tubing sand clean-out operation and the TTSS retrieval via coil tubing deployment. The project design process, involving evaluation of methods and equipment suitable for this operation, is also discussed in this paper. The success of this project proves that a combination of efficient choices, with the utilization of coiled tubing for cleanout, and collaborative work between coiled tubing and other service providers for the TTSS retrieval, can be implemented for retrieval of lengthy downhole accessories. Sand production has become one of the most difficult challenges for mature oil fields, adversely affecting well deliverability and potentially contributing to well shut-in and surface equipment failure. Offshore facilities are not typically designed to handle sand long-term, resulting in well closures when sand production becomes excessive. Various efforts can be implemented to enhance the sand handling capacity or minimize sand exposure to surface, among them is by installing a Through-Tubing sand screen (TTSS). TTSS is easy to install, and its low-cost wireline operation makes it one of the preferred choices to address sand issues. This method, however, requires periodic maintenance and replacement to remain efficient. Excessive sand production caused by failures in both primary and remedial sand control measures eventually leads to the accumulation of sand within the production tubing. A longer TTSS can be installed to increase the longevity and durability of the TTSS. However, installation of long accessories also presents a retrieval challenge. One solution as presented in this paper is to utilize the coil tubing to provide efficient cleaning of debris above the TTSS and sufficient jarring force to release TTSS from tubing. The retrieval of TTSS on surface, however, is limited by the stackup length afforded on surface to allow proper securing of well prior to retrieval. This challenge is overcome by implementing coiled tubing deployment method to secure TTSS on surface into coiled tubing stackup, isolate well from surface safely, and handing over to wireline for the full retrieval of tool above wellhead. The overall workflow of this project allows for the successful retrieval of the TTSS to surface and can be considered in mind when designing the installation and/or retrieval of other lengthy toolstring/downhole completions.

Streszczenie:

Abstract Tendon Tension Monitoring Systems (TTMS) are commonly installed on Tension Leg platforms (TLPs) to measure the axial tensions in the tendons. These measurements are essential to the weight management of the platform, and in monitoring their fatigue life. The TTMS typically consists of 3 load cells per tendon, with 2 bridge measurements for each load cell. This makes up to 6 tension measurements per tendon allowing for a good number of redundant measurements for tendon tension determination. This system design with redundant measurements allows for long term integrity monitoring of the TLP, and some of these systems have been in operation for over a decade. However, the degradation of the load cells over time due to harsh environments, wear and tear, reduces the reliability of the tension measurement system. This study investigates the use of machine learning (ML) to model tendon tensions using historical TTMS data with reduced number of reliable tension measurements. Building models, training and validation of these models are evaluated and presented to demonstrate how ML can provide reasonable tension estimates and help extend the useful life of the TTMS. Outputs from these models are presented and discussed, with a focus on accuracy in relation to the number of model inputs. Observations from models simulating reduced inputs with no TTMS measurements from at least one tendon are elucidated. This paper demonstrates how ML from TTMS data can estimate tendon tensions reasonably, with a reduced number of reliable measurements. Implementation of these techniques can help to extend the useful life of these TTMS.

We provide evidence that financial distress induces firms to sell their technology to foreign competitors. To do so, we construct a novel, spatial panel dataset by individually researching and locating U.S. firms who signed Technology Transfer Agreements (TTAs) with the Soviet Union during the 1920s and 1930s in various U.S. counties. By relating the number of TTAs signed in each county to the number of bank failures, we establish a significant, positive relationship between financial distress and the number of firms signing TTAs with the Soviet Union. Our findings suggest that banking panics may create opportunities for foreign countries to acquire affected firms’ technology.

Streszczenie:

There is a significant knowledge gap for Army doctrine concerning civilian research scientists. A relatively small number of soldiers make the transition from warfighter to research and development at the basic and applied levels. That number is even less when considering former warfighters that have applied Army doctrine in an operational or advanced Army schooling environment. This special report is intended to focus solely on the Army’s current capabilities and doctrinally defined processes to analyze vegetation as an essential component of the natural terrain. The objective of this report is to review current Army doctrine related to analysis of the vegetated terrain; to explore currently leveraged tactics, techniques, and procedures (TTPs); and identify valuable geospatial resources as they apply to military planning. For ease to readers unfamiliar with US Army doctrine, much of the referenced material is directly presented herein as tables and figures throughout the document and appendices (e.g., data sources, product examples, and glossary).

Streszczenie:

Threat actors, including infamous cybercrime groups and financially driven ransomware gangs, have focused on Arab countries› businesses and organizations as they grow and move toward digital transformation. In particular, ransomware is a very serious type of cyber-attack worldwide, and many organizations are severely affected by it. INTERPOL indicates that the ransomware gangs are targeting different regions such as Africa, Americas, Caribbean, Asia-Pacific, Europe, Middle East, and North Africa 1. The Center of Excellence in Cybercrime and Digital Forensics (CoECDF) at NAUSS has conducted a deep web search, collecting, analyzing, and classifying data on ransomware gangs targeting Arab countries and organizations from 2020 to 2022. We have collected the information of ransomware victims through the darknet and dark web, focusing on leaked information. This report focuses on the Arab countries, organizations, and sectors victimized by ransomware gangs and whose information has been leaked on the darknet. Moreover, it investigated ransomware gangs that carried out cyberattacks against Arab countries, and the tactics, techniques, and procedures (TTPs) they were using. The number of organizations that are attacked by ransomware gangs is increasing significantly. Some organizations pay ransom to ransomware gangs in order not to publish their information on the darknet. As a result of not paying the ransom demanded by the ransomware gangs, certain organizations and countries had their private and sensitive data leaked to the dark web. The purpose of this report is to help law enforcement agencies combat ransomware cyberattacks by providing them with insights into the evolving tactics of ransomware gangs. By understanding how these gangs operate, law enforcement agencies can better prepare to combat and respond to ransomware attacks.
