The document discusses modeling and analyzing test data from the ENSA/DOE test campaign to transport spent nuclear fuel. It will involve processing terabytes of continuously recorded acceleration, strain, and event data. Models will be used to determine if strain gauges captured peak strains, evaluate fatigue on individual fuel rods and assemblies, and relate test results to real spent fuel transportation. Accounting for factors like fuel rod stiffness, material properties, and transport conditions is needed to complete the story and ensure safety.

Recent Developments in Computational Methods for the Analysis of Ducted Prope...João Baltazar
This document discusses recent developments in computational methods for analyzing ducted propellers in open water. It presents two main computational methods - Boundary Element Method (BEM) and Reynolds-Averaged Navier-Stokes (RANS) simulations. Grid refinement studies are performed to estimate discretization errors for the BEM method. Contributions to iterative errors are also analyzed for both BEM and RANS calculations. The document aims to develop an accurate and cost-effective numerical tool by coupling BEM and RANS methods for propeller design studies.
The document discusses different formulations of the search-based software project scheduling problem:
1) A basic formulation aims to minimize project cost and duration by assigning employees to tasks while satisfying constraints like all tasks being performed and employee skills matching task requirements.
2) A multi-objective formulation considers both minimizing project cost and duration as objectives rather than a single objective.
3) Additional formulations include robust formulations to handle uncertainty and preference-based formulations to include decision-maker preferences.
The document outlines the objectives, constraints, and solution representations used for the different problem formulations.
Recent Developments in Computational Methods for the Analysis of Ducted Prope...João Baltazar
This paper presents an overview of the recent developments at IST and MARIN in applying computational methods for the hydrodynamic analysis of ducted propellers. The developments focus on the propeller performance prediction in open water conditions using Boundary Element Methods and Reynolds-averaged Navier-Stokes solvers. The paper starts with an estimation of the numerical errors involved in both methods. Then, the different viscous mechanisms involved in the ducted propeller flow are discussed and numerical procedures for the potential flow solution proposed. Finally, the numerical predictions are compared with experimental measurements.

Self-charging, Highly Accurate Insole-Based Health Trackers for Medical Grade...INVIZA® HEALTH
INVIZA® HEALTH generates power from piezoelectric, mechanical energy harvesting to enable its health and fitness sensor suite. In addition, by using multiple sensor's output data via software, i.e. "sensor fusion" INVIZA has learned to lower power overall sensor and electronics power consumption while simultaneously increasing health and fitness measured parameter's accuracy. This leads to the insole tracker's battery staying 100% full while the user obtains the most accurate data.
Bagging Exponential Smoothing procedures have recently arisen as an innovative way to improve forecast accuracy. The idea is to use Bootstrap to generate multiple versions of the time series and, subsequently, apply an Exponential Smoothing (ETS) method to produce forecasts for each of them. The final result is obtained aggregating the forecasts. The main drawback of existing procedures is that Bagging itself does not avoid generating highly correlated ensembles that might affect the forecast error. In this paper we propose and evaluate procedures that try to enhance existing Bagging Exponential Smoothing methods by an addition of a clustering phase. The general idea is to generate Bootstrapped versions of the series and use clusters to select series that are less similar among each other. The expectation is that this would reduce the covariance and, consequently, the forecast error. Since there are several cluster algorithms and dissimilarity measures, we consider some of them in the study. The proposed procedures were evaluated on monthly, quarterly and yearly data from the M3-competition. The results were quite promising, indicating that the introduction of a cluster phase in the Bagging Exponential Smoothing procedures can reduce the forecast error.
This document summarizes a study that used a micro-task tablet application to test operator performance with innovative versus conventional control room displays. Over 5 hours of simulator time with 20 operators, the study collected over 6,800 data points on response times and accuracy for identification and decision-making tasks. The results showed that operators were significantly faster with the innovative displays compared to conventional, with only slightly lower accuracy. The innovative displays were found to be as reliable as conventional displays but faster to read. Next steps discussed include comparing analog control room performance to a human-machine laboratory and obtaining reference data.
Toshiba presented their machine translation system for the WAT2015 workshop. Their system uses statistical post-editing (SPE) to correct rule-based machine translation (RBMT) output. It also combines SPE and phrase-based statistical machine translation (SMT) results by reranking the merged n-best lists using a recurrent neural network language model. Evaluation showed the combined system achieved the best results on most language pairs compared to SPE and SMT individually. Analysis of system selections by the combination found it primarily chose translations from SPE.
Decision Making Using The Analytic Hierarchy ProcessVaibhav Gaikwad
Analytic Hierarchy Process (AHP) is an
effective tool for dealing with complex decision making,
and may aid the decision maker to set priorities and
make the best decision. By reducing complex decisions
to a series of pairwise comparisons, and then
synthesizing the results, the AHP helps to capture both
subjective and objective aspects of a decision. In
addition, the AHP incorporates a useful technique for
checking the consistency of the decision maker’s
evaluations, thus reducing the bias in the decision
making process. In this paper we give special emphasis
to departure from consistency and its measurement and
to the use of absolute and relative measurement,
providing examples and justification for rank
preservation and reversal in relative measurement.
The document discusses various concepts related to scheduling operations in manufacturing. It defines scheduling as specifying when labor, equipment, and facilities are needed to produce products. The objectives of scheduling are outlined as meeting due dates, minimizing lateness and overtime, and maximizing resource utilization. Different sequencing rules for prioritizing jobs are presented, such as first-come first-served, earliest due date, shortest processing time, and minimum slack. Examples are provided to illustrate how different sequencing rules can impact the flow time, makespan, and tardiness of jobs.

This document discusses how Irish hospitals can benefit from benchmarking. It provides background on cost per patient benchmarking in the Dutch DRG system. Benchmarking involves comparing a hospital's costs and processes to peers in order to identify areas for improvement. The document outlines how benchmarking has been implemented in the Netherlands through connecting various data sources, developing a cost model, and using benchmarks in management. It emphasizes that benchmarking requires technology, but also top management commitment to discussions with doctors and using benchmarks in budgeting. The document concludes that while technology is important, benchmarking can be achieved today in Ireland through getting financial control and performing better despite budget constraints.

Ash also identified leak testing equipment and procedures for the LCM, and researched vacuum chamber options for leak testing. Through the rotation, Ash learned about thermal measurements, gradient coil performance evaluation, acoustic and vibration testing procedures, and the importance of clear documentation.
T he SPL - IT Query by Example Search on Speech system for MediaEval 2014multimediaeval
This document briefly describes the system submitted by the Speech Processing Lab of Instituto de telecomunicações, pole of Coimbra (SPL-IT) to the Query by Example Search on Speech Task (QUESST) of MediaEval 2014. Our approach is based on merging results of a phoneme recognition system using three different languages. A version of Dynamic Time Warping (DTW) using posteriorgram distances was created to allow finding
some of the peculiar search cases of this task. Our primary submission merges two approaches: simple DTW
for detecting entire queries and a version where cutting final portions of queries is allowed. The late submission merges 5 approaches that account for all the search possibilities described for the task, though improved results
were only observed in the evaluation dataset for type 3 queries.

This document discusses near-optimal sensor placement for linear inverse problems. It introduces the concept of using sensors to measure physical fields and describes how inverse problems aim to estimate parameters of interest from sensor measurements. It presents the FrameSense algorithm, which uses a greedy approach to minimize frame potential as a proxy for minimizing mean squared error in sensor placement. FrameSense provides near-optimal sensor placement for linear inverse problems in polynomial time. As an example application, the document describes how FrameSense can be used for optimal placement of temperature sensors on a microprocessor to reconstruct thermal maps from sparse measurements.
The document summarizes experiences with the Land Parcel Identification System (LPIS) Quality Assessment Framework (QAF) in several European countries. It finds that:
1) Implementing the LPIS QAF is complex and time-consuming, requiring substantial effort from member states in both time and costs. Meeting all thresholds poses a challenge.
2) Preliminary results show that most countries are not fully complying with some quality elements, especially those relating to the proportion of reference parcels with incorrectly recorded areas.
3) Different LPIS implementations (agricultural parcel, farmer's block, physical block) result in different experiences, and waivers may be needed to make the QAF fit different systems.
Convolutional Neural Network to Model Articulation Impairments in Patients wi...Juan Camilo Vasquez
This document describes a study that used convolutional neural networks (CNNs) to model articulation impairments in patients with Parkinson's disease (PD) based on their speech. The study analyzed time-frequency representations of voiced-unvoiced transitions detected in speech recordings from PD patients and healthy controls. CNNs were trained on these representations to classify speakers. The models achieved over 85% accuracy classifying same-language data and around 55% for cross-language classification. The CNN approaches outperformed baselines when training and testing used the same language but additional methods are needed for cross-language tasks. The authors conclude CNNs are effective for this application but recurrent networks should also be explored to model co-articulation.
Noise Pollution in Hospital Readmission Prediction: Long Document Classificat...Jinho Choi
This document discusses using reinforcement learning for hospital readmission prediction from clinical notes. It presents an approach that uses a bag-of-words encoder with an RL agent to perform automatic noise pruning. The RL agent is able to identify and remove noisy tokens and text segments, improving performance over strong baselines. Experimental results show the RL method achieves better performance than deep learning approaches, while reducing the feature space to alleviate overfitting on this small clinical dataset.
1) The document discusses condition based monitoring (CBM) of ultrasonic gas flow meters using internal diagnostics to validate performance over time.
2) It introduces a new CBM meter design using a 4-path meter alongside a single-path reference meter, allowing real-time comparison to detect issues.
3) Testing showed the single-path meter response was more significant than the 4-path when flow conditions changed (e.g. blocked flow conditioner), enabling earlier issue detection.
Syntax-based Simultaneous Translation through Prediction of Unseen Syntactic ...Yusuke Oda
This study proposes two methods for syntax-based simultaneous translation: 1) predicting and using unseen syntactic constituents, and 2) waiting for translation to avoid reordering problems. Experimental results on English to Japanese translation show the proposed approach prevents decreases in translation accuracy for short phrases compared to baselines, and provides more robustness to reordering. However, constituent prediction accuracy remains low due to redundant constituents in the gold syntax. Future work includes improving prediction and using additional context features.
Tiny MEMS digital barometer for smartphones and wearables
The first barometric sensor from Infineon for the consumer market is targeting altitude, GPS, indoor and weather forecasting applications in portable devices. This MEMS sensor positions Infineon to compete with STMicroelectronics and Bosch Sensortec.
Infineon’s DPS310 pressure-sensing device is manufactured using a proprietary MEMS technology developed for and already sold for several years in the automotive market. The sensing element in the DPS310 is based on a flexible silicon membrane formed above an air cavity with a controlled gap and defined internal pressure. The membrane is very small compared to traditional silicon micro-machined membranes. Moreover, Infineon has developed a capacitive sensor to be more accurate and less sensitive to temperature change compared to piezoresistive solutions.
For the DPS310, Infineon has introduced two important innovations. The first is a two-die solution more scalable than the monolithic solution used for some automotive pressure sensors.
The second innovation is a plastic metallized lid to replace the classic metal lid. The device comes in a tiny 2x2.5x0.9mm HLGA molded package.
The report presents a detailed analysis of the sensor’s structure and cost. Comparison with the characteristics of the STMicroelectronics pressure sensor LPS22HB and the Bosch Sensortec BMP280 highlights differences in technical choices made by the companies.

This document discusses the pros and cons of statistical machine translation (SMT) and neural machine translation (NMT) for translation service providers and their clients. While NMT produces more fluent translations, it is harder to control and needs extensive testing, making SMT more predictable. MT can help increase translator productivity but only if the right conditions are met, such as content suited to MT, sufficient volume, and supportive workflows. Overall, MT is best viewed as a tool to aid translators rather than replace them, and human factors like motivation and compensation are important to realize any productivity gains.
The document discusses the development of KantanNeuralTM, a neural machine translation platform. It describes how the time to build neural machine translation engines has decreased from 4 weeks to 4 days to potentially 4 hours. The platform allows users to build, improve, and deploy their own neural machine translation engines through an easy-to-use interface. The system also supports seamless switching between statistical and neural machine translation methods.

Tony (Chief Architect, KantanMT.com) opens the proceedings with a temporal look at how MT technology has progressed. While embracing Rule Based MT in the 1970s, the industry switched over to Statistical MT around 2002 and is now faced with a new paradigm of Neural MT in 2016. For each technology progression, improved translation quality and fluency were achieved.

ATC Summit 2016: The 7th Habit of 7 Habits of Effective MT Systemskantanmt
Translation quality management is key for Project Managers to improving the translation process. Producing high quality translations from the start of projects will reduce costs and improve speed to market.
When considering automated translation, we think of automatic metrics, such as BLEU, F-Measure and TER and how they can correlate with the translation quality. However, the step of reviewing translation output for MT engine retraining is still a very manual process incorporating multiple iterations of excel documents. In this presentation, Brian will discuss how the process can be automated and the impact automation will have on reducing costs and increasing translation productivity.

Psaroudakis: Family and Football – The Psaroudakis Success StoryPsaroudakis
Psaroudakis, a name that resonates with football fans around the globe, is a testament to the powerful synergy between familial support and individual passion. Born on March 10, 1992, in the historic city of Heraklion, Crete, Psaroudakis’ journey to international football stardom is a compelling narrative of dedication, perseverance, and unwavering family support. His story not only highlights his athletic prowess but also underscores the crucial role his family played in shaping his career and character.
Psaroudakis’ early life in Heraklion was deeply influenced by a supportive and nurturing family environment. His father, a former semi-professional footballer, recognized Psaroudakis’ potential from an early age. Acting as his first coach, his father’s guidance was instrumental in igniting Psaroudakis’ passion for football. This paternal influence instilled in him a strong work ethic and fundamental skills that would become the foundation of his future success. His mother, a dedicated homemaker, provided a stable and nurturing environment, ensuring that Psaroudakis could pursue his dreams without any hindrances.
From a young age, Psaroudakis showed an innate talent for football. Growing up in Heraklion, he spent countless hours playing football in local parks and streets with friends and family. His natural ability was evident even in these informal settings, and his enthusiasm for the game was infectious. By the age of five, Psaroudakis had joined a local youth football club, where his skills began to flourish. His father’s role as his first coach during these formative years was crucial, as he emphasized not only technical skills but also the importance of discipline and teamwork.
The transition from playing in local parks to joining a structured football environment marked a significant step in Psaroudakis’ journey. At the age of ten, he joined the youth academy of OFI Crete, one of Greece’s most esteemed football clubs. This move marked the beginning of a more rigorous and professional approach to his training. The academy environment was demanding, focusing on honing technical abilities and instilling values of sportsmanship and dedication. Psaroudakis’ dedication to his craft was evident as he quickly rose through the ranks, becoming a standout player in the youth teams.
The support of Psaroudakis’ family was unwavering during this critical period. His father continued to be a source of guidance and mentorship, while his mother ensured that he had everything he needed to succeed. Their collective efforts created a balanced environment where Psaroudakis could focus entirely on his development as a footballer. This familial support was not just about providing the basics; it was about creating an environment where Psaroudakis felt encouraged and motivated to pursue his dreams relentlessly.
As Psaroudakis transitioned from the youth academy to professional football, the challenges became more significant.

According to the PBSMT paradigm, a sentence is translated phrase by phrase. The translation of each phrase is derived from a phrase table (i.e., a representation of a translation model). Then these phrase-level translations are combined in a sentence in a way that maximises the likelihood for a correct sentence in the target language (i.e., using a language model). Sometimes a third model is used to fix the casing.

Next we aimed to investigate our hypothesis of BLEU underestimating NMT quality. In order to do so, we needed to find irregularities between human evaluation and BLEU scores. To do so, first, we took the set of translations, for each language pair and from the set that the reviewers evaluated, where NMT was marked by all three reviewers better. Next, from this set we counted the number of translations with BLEU score lower than their PBSMT counterparts. Third, we find the ration of the two counts.
We did the same also for the PBSMT – get the set of better translations, count the ones with BLEU score lower than the NMT counterparts and calculate the ration between the two numbers.
It is clear from our results that indeed, the BLEU is not that reliable for NMT. Furthermore, these results indicate that BLEU underestimates the quality, thus confirming our hypothesis.
Now, can we actually trust BLEU??? There are several remarks that need to be noted. First, the numbers shown in our table for each language pair are similar – this means that the affect of the BLEU underestimation is the same among the NMT engines, that is – we can compare NMT engines based on BLEU and still get a sense of their quality differences; Second, we notice the same tendency in the F-Measure score, which is also a metric based on n-grams. That indicates that indeed the issues arise from the underlying principles of PBSMT and NMT (recall the 2D picture with the points linked to the John/Mary sentences). This can push the future research in quality estimation in a particular direction.
And third, something not shown in a table or a graph. Remember that our engines are trained under a time restriction. Assume we let the training continue until the neural network reaches its full potential. That is, it will model optimally the training data. Given that the test data is very similar to the training data this would mean that the engine would model each test sentence also very well, even on a phrase level. And as such, the scores (BLEU, F-Measure and TER) would improve and get closer or even surpass the PBSMT scores. This statement is supported by other research where (e.g., google’s paper from November last year) shows very good scores but also each of their models is trained for almost two weeks.
A translation production line nowadays typically combines an MT component with human post-editing. While the MT component is simply a means to get a raw translation of the original text, which in the next step is modified to meet certain translation quality standards, the choice of correct MT toolset impacts the efficiency of this pipeline.
