Finding Significant Features for Few-Shot Learning using Dimensionality Reduction Techniques
Authors: Mendez Mauricio , Garcia Ivan , Mendez-Vazquez Andres , Ochoa-Ruiz Gilberto
Published: December 2022

ew-shot learning is a fairly new technique that specialize in problems where we have little amount of data. The goal of this method is to classify categories that hasn’t been seen before with just a handful of samples. Recent approaches, such as metric learning, adopt the meta-learning setting in which we have episodic tasks conformed by support (training) data and query (test) data. Metric learning methods has demonstrated that simple models can achieve good performance, by learning a similarity function to compare the support and the query data. However, the feature space learned by the metric learning may not exploit the information given by a specific few-shot task. In this work, we explore the use of dimension reduction techniques as a way to find task significant features. We measure the performance of the reduced features by giving a score based on the intra-class and inter-class distance, and select the method in which instances of different classes are distant and instances of the same class are close. This module helps to improve the accuracy performance by allowing the similarity function, given by the metric learning method, to have more discriminative features for the classification.
Hair removal in dermoscopic images using deep multitask learning
Authors: Talavera-Martinez Lidia , Gonzalez-Hidalgo Manuel , Bibiloni Pedro
Published: December 2022

When analyzing dermoscopic images, the hairs and their shadows on the skin may occlude relevant information about the lesion at the time of diagnosis. In this work, we present a new approach for hair removal on dermoscopic images based on deep learning techniques, as well as study in depth the behavior of the tasks of skin lesion segmentation, hair mask segmentation, and inpainting of those regions, in a multitasking framework to discover how tasks influence each other. Moreover, we describe our built database specifically for the task of hair removal. Qualitative and quantitative results demonstrate the efficacy of our model. Finally, we conclude from the multitasking experimentation that while the inpainting task does not benefit from this type of learning, the rest of the tasks do benefit by improving their performance compared to their corresponding single-task model.
Distributed Text Representations Using Transformers for Noisy Written Language
Authors: Rodriguez Alejandro , Rivas Pablo , Bejarano Gissella
Published: December 2022

This work proposes a methodology to derive latent representations for highly noisy text. Traditionally in Natural Language Processing systems, methods rely on words as the core components of a text. Unlike those, we propose a character-based approach to be robust against our target texts’ high syntactical noise. We propose pre-training a Transformer model (BERT) on different, general-purpose language tasks and using the pre-trained model to obtain a representation for an input text. Weights are transferred from one task in the pipeline to the other. Instead of tokenizing the text on a word or sub-word basis, we propose considering the text’s characters as tokens. The ultimate goal is that the representations produced prove useful for other downstream tasks on the data, such as criminal activity in marketplace platforms.
Proactive Detractor Detection Framework Based on Message-Wise Sentiment Analysis Over Customer Support Interactions
Authors: Salcedo Juan , Solano Jesus , Garcia Hernan , Zarruk David , Correa-Bahnsen Alejandro
Published: December 2022

In this work, we propose a framework relying solely on chat-based customer support (CS) interactions for predicting the recommendation decision of individual users. For our case study, we analyzed a total number of 16.4k users and 48.7k customer support conversations within the financial vertical of a large e-commerce company in Latin America. Consequently, our main contributions and objectives are to use Natural Language Processing (NLP) to assess and predict the recommendation behavior where, in addition to using static sentiment analysis, we exploit the predictive power of each user’s sentiment dynamics. Our results show that, with respective feature interpretability, it is possible to predict the likelihood of a user to recommend a product or service, based solely on the message-wise sentiment evolution of their CS conversations in a fully automated way.

Authors: Majeed Nomana Ayesha , Kouyem Alex Kemloh
Published: December 2022

Randomness is a critical issue in peer-to-peer networks because random numbers allow us to fairly select the candidates, resolve the lotteries, select block producers, etc. The difficulty is that each participant wants to verify that the random number was randomly generated, this led to the invention of verifiable random functions (VRF). The VRF is a pseudo-random function that provides a solution to blockchain-based random number generation.
This paper focuses on the implementation of an elliptic curve-based VRF introduced by NIST called ECVRF-secp256r1 in Solidity. The algorithm verifies the randomness on-chain, tests the gas consumption at each stage, and compares it to the ECVRF-secp256k1.

Authors: Petschauer Sarah , Franke Gabriele Helga , Häring Martin , Blaser Marion , Jagla-Franke Melanie
Published: December 2022

The aim of the present study is to examine whether the emotion regulation of patients and "healthy" people differs. The BDI-II, the FEEL-E, the SCL-90®-S and the EFK were used to test for group differences, the influence of gender, age and depression as well as the prediction of depression. As expected, patients (N=85) showed higher levels of depression and higher psychological stress than the comparison group (N=67), regardless of age and gender, although they rather tended to use maladaptive emotion regulation strategies. High levels of depression were associated with maladaptive emotion regulation and can be predicted by specific strategies. Thus, in contrast to “healthy” people, those suffering from depression exhibit a dysfunctional emotion regulation.

Ultra-high-speed time-resolved PIV of turbulent flows using a continuously pulsing fiber laser
Authors: Geschwindner Christopher
Published: December 2022

The application of a compact pulsed fiber laser for high-speed time-resolved particle image velocimetry (TR-PIV) measurements in the potential core of a turbulent round jet is presented at repetition rates of up to 500kHz. The master oscillator power amplifier laser architecture consists of a pulsable seed diode whose emission is amplified in a Yb-doped fiber. The pulsed laser is operated continuously at repetition rates ranging from 10kHz to 1MHz with adjustable pulse widths at an output power of 50 W. The maximum rated pulse energy of 486μJ is reached at 100kHz, making the laser suitable for measurements of turbulent flows and highly transient phenomena. To demonstrate the feasibility of the laser for flow velocimetry, TR-PIV is conducted in a turbulent round jet. Two different high-speed camera systems are employed: a high-speed CMOS camera running at 200kHz and 400kHz and an in situ storage CCD camera for burst-mode PIV measurements at 500kHz. For the CMOS system, the capability of measuring several characteristic quantities of turbulent flows is discussed with regard to the effects of uncertainty and spatial resolution. The presented system extends the range of suitable laser systems for high-speed PIV measurements offering continuous pulsing at repetition rates of up to 1MHz at a compact footprint. The amount of consecutive images is solely limited by the onboard storage of the camera, which enables unprecedented temporal dynamic ranges.

IDENTIFICATION OF CHANGES IN THE METABOLIC PROCESSES OF GERMINATION AND GROWTH OF MAIZE SEEDLINGS UNDER THE INFLUENCE OF HEAT STRESS AND THE USE OF REGLALG
Authors: Cauș Maria , Dascaliuc Alexandru , Borozan Pantelimon
Published: December 2022

Laboratory experiments were carried out to determine the effect of pretreatment of seeds of two hybrids of maize (Zea mays L.) with Reglalg and subsequent exposure to heat stress (HS) of 50°C for 30 min on seed germination, seedling growth and assessment of translocation of endosperm reserve substances for these processes. The results showed a positive effect of Reglalg on seed germination and seedling growth parameters, which were affected by HS conditions. The use of Reglalg to treat the seeds of maize hybrids before expose to HS, had a beneficial effect on the formation of seedling biomass due to an increase in the mass of endosperm translocated from seeds to these processes under the conditions of stress. Also, the use of Reglalg in seed pretreatment favored the decrease in endosperm mass consumed for cellular metabolism respiration under HS.

From the total number of projects accessed, a number of 28 projects represented the establishment of new plantations and 6 projects aimed at modernization of holdings, i.e., a percentage of 82.3% is represented by new plantations. It is found that, at the level of the SW Oltenia Region, the fruit-growing areas have increased, which leads to the idea that from this point of view, the impact of the non-reimbursable funds was significant. The existence of future European programmes for the fruit-growing sector will allow the competitiveness of fruit-growing holdings to increase.

Published: December 2022

Okra is a particularly appreciated vegetable for its specific taste. The pods are green up to 30 cm long and up to 4 cm in diameter, used in the immature phase in various dishes in the food field, but also medically, as an antidiabetic remedy. Research by specialists on a variety of plant material shows that some environmental conditions influence seed production. The experience was carried out in 2021 on the Acme and Smaranda okra varieties. The total production of okra seeds obtained in the seed culture was determined, as well as the number of capsules per plant, the size of the capsules, the number of seeds/capsule and the mass of 1000 seeds. The obtained results show that the variety Smaranda had a higher number of seeds and a negative linear correlation in the variety Smaranda and a positive linear correlation in the variety Acme between the length of the capsule and the number of seeds The environmental conditions experienced influenced the production of okra seeds.

Authors: Noguera Pérez Francisca
Published: December 2022

Este proyecto se realizó en el Centro Escolar Salesiano «San Juan Bosco» en el municipio de Cartagena, Murcia. Consiste en llevar a cabo el acompañamiento de un alumno con discapacidad visual con el objetivo de conseguir que tenga autonomía en sus desplazamientos por el centro. Para ello, utiliza a sus iguales como medio, a través de la imitación, siempre desde una perspectiva lúdica. De este modo, se trabajan con el alumno, a nivel individual, competencias tales como normas básicas de cortesía y convivencia, orientación espacial y autonomía personal. Hacemos hincapié en el trabajo que se realiza a nivel general con todo el alumnado, tanto activo como pasivo, de toda la etapa de educación primaria, incluyendo aquellos que acompañan al alumno, así como los que comparten espacios comunes con él (patio de recreo, baños, comedor escolar, etc.). Todo ello implica la concienciación del alumnado de las características especiales del alumno con discapacidad visual. De igual manera, aprenden las indicaciones y herramientas concretas que tienen que seguir para orientarlo y acompañarlo en su desplazamiento, trabajando múltiples valores, como empatía, compañerismo, solidaridad, respeto, ayuda al prójimo, responsabilidad y confianza. La clausura del proyecto, realizado durante dos cursos académicos, tuvo como resultado valoraciones muy satisfactorias tanto para el alumno con discapacidad visual como para el resto de sus compañeros, alcanzando así los objetivos propuestos al inicio del mismo.

Aluminum alloy A5E was selected as a matrix of high-strength aluminum wrought alloys, and copper M0 and M1 grades was chosen as an alloying element. As a result of comprehensive studies, a technology for casting aluminum wrought alloys of the Al-Cu-Fe-Si system was developed, and optimized casting modes for aluminum wrought alloys with a copper content of 5,7...6,5% were substantiated and selected, according to which the temperature of casting the melt should be within 730 ± 100С, the temperature of the mold is 120 ± 100С, while the fluidity is 430 mm, linear compression is 1,6...1,65%, HB = 1230...1250 MPa, σв = 415...420 MN / m2, δ = 6...7%.
It is shown that the casting properties of aluminum alloys, such as fluidity, linear shrinkage and liquation, strongly depend on the chemical composition of the alloy, its structure, liquidus and solidus temperatures, heat capacity, thermal conductivity, etc.
DEVELOPING A TECHNOLOGY FOR OBTAINING FERROMOLIBDENUM FROM MOLYBDENUM CONCENTRATE OF TEGHUT BY THE METHOD OF HIGH-TEMPERATURE SELF-PROPAGATING SYNTHESIS
Authors: ZAKARYAN E.G.
Published: December 2022

Teghut molybdenum sulfide concentrate and its molybdenum minerals have been shown to undergo deep mechanochemical transformations as a result of dispersion crushing in air and water, replacing the chemical processes that take place during the roasting phase.
For the first time, a combination of mechanochemical and metallothermal processes of Teghut molybdenum sulfide concentrates was carried out, as a result of which, a fixed product of non-traditional mode was obtained, and bypassing the pre-firing process of the concentrate, environmental issues were solved.
Theoretical, kinetic and technological regularities and peculiarities of the direct, unheated metal-thermal reduction process of Teghut pre-mechanically activated molybde¬n¬u¬m sulfide concentrates have been revealed. Theoretical issues related to the mechanism of the aluminum-thermal recovery process were clarified.

Published: December 2022

During the inspections performed at the NPP, many system components are chec¬ke¬d. Traditional deterministic inspections are mostly based on the data from the known ope¬r¬a¬t¬i¬n¬g experience, without considering the risk significance of the components. One of the in s¬er¬v¬i¬ce inspection routes includes checking the components and pumping stations of ESW (Esse¬n¬t¬ial service water) system. For the system, it is shown that replacing the traditional determin¬is¬t¬i¬c inspections by risk informed ones will allow to correctly identify the components to be chec¬k¬ed during inspections, which will significantly increase the efficiency of inspection and reduce the probability of the system failure several times
EFFICIENCY OF GETTERING STRUCTURAL DEFECTS BY A BLACK SILICON LAYER
Authors: AYVAZYAN G.Ye.
Published: December 2022

The possibility of gettering structural defects of silicon substrates with a near-surfa¬ce layer of black silicon (b-Si) is considered. The gettering efficiency was estimated according to the results of studying the resistivity, defect density, and effective minority carrier lifetime on test and control substrates. It is shown that in the thermal oxidation process, the b-Si layer serves as an effective drain for excess interstitial atoms and metallic impurities, thereby significantly reducing the density of nuclei of structural defects in silicon. As a result, the resistivity of the substrates decreases, and the carrier lifetime increases. It is advisable to form a b-Si layer as a getter on the rear non-working side of the substrates.
СИСТЕМА ОПРЕДЕЛЕНИЯ КООРДИНАТ НАЗЕМНЫХ ОБЪЕКТОВ С БЕСПИЛОТНЫХ ЛЕТАТЕЛЬНЫХ АППАРАТОВ ПРИ ОТСУТСТВИИ СИГНАЛОВ GPS

Published: December 2022

Многороторные беспилотные летательные аппараты (БПЛА) широко испол-ь¬зуются в различных военных и гражданских областях. Полет БПЛА по заданным тра¬е¬¬к¬ториям при этом осуществляется с использованием сигналов GPS, которые оп¬ре¬де¬ля¬ю¬¬т координаты аппарата с точностью от десятков сантиметров до нескольких метров. Од¬нако на практике возможны ситуации, когда сигналы GPS искажены или отс¬ут¬ств¬у¬ю¬т. В таких случаях важной задачей является определение как координат самого БПЛА, так и координат наземных объектов, за которыми осуществляется наблюдение с БП¬Л¬¬А.
В работе предлагается подход к определению геодезических координат БПЛА и наземных целей в случае, когда сигналы GPS отсутствуют, но известны коор¬ди¬на¬т¬ы двух наземных, так называемых “опорных” объектов. В качестве опорных выби¬раю¬т¬с¬я объекты, которые выделяются на фоне местности и могут быть легко иденти¬фи¬ци¬ро¬ваны, например, отдельные строения, опоры линий электропередач, радиорелейные мачты и т.д. Разработан графический интерфейс пользователя в среде пакета MAT¬LA¬B, позволяющий автоматизировать процедуру расчета координат БПЛА и цели при отсутствии сигналов GPS.
