A Strip Adjustment Method of UAV-Borne LiDAR Point Cloud Based on DEM Features for Mountainous Area
Authors: Chen Zequan , Li Jianping , Yang Bisheng
Published: April 2021

Due to the trajectory error of the low-precision position and orientation system (POS) used in unmanned aerial laser scanning (ULS), discrepancies usually exist between adjacent LiDAR (Light Detection and Ranging) strips. Strip adjustment is an effective way to eliminate these discrepancies. However, it is difficult to apply existing strip adjustment methods in mountainous areas with few artificial objects. Thus, digital elevation model-iterative closest point (DEM-ICP), a pair-wise registration method that takes topography features into account, is proposed in this paper. First, DEM-ICP filters the point clouds to remove the non-ground points. Second, the ground points are interpolated to generate continuous DEMs. Finally, a point-to-plane ICP algorithm is performed to register the adjacent DEMs with the overlapping area. A graph-based optimization is utilized following DEM-ICP to estimate the correction parameters and achieve global consistency between all strips. Experiments were carried out using eight strips collected by ULS in mountainous areas to evaluate the proposed method. The average root-mean-square error (RMSE) of all data was less than 0.4 m after the proposed strip adjustment, which was only 0.015 m higher than the result of manual registration (ground truth). In addition, the plane fitting accuracy of lateral point clouds was improved 4.2-fold, from 1.565 to 0.375 m, demonstrating the robustness and accuracy of the proposed method.

Authors: Shin Dongbin , Lee Seungchan , Hwang Seunghoon
Published: April 2021

The number of elderly people has increased as life expectancy increases. As muscle strength decreases with aging, it is easy to feel tired while walking, which is an activity of daily living (ADL), or suffer a fall accident. To compensate the walking problems, the terrain environment must be considered, and in this study, we developed the locomotion mode recognition (LMR) algorithm based on the gaussian mixture model (GMM) using inertial measurement unit (IMU) sensors to classify the five terrains (level walking, stair ascent/descent, ramp ascent/descent). In order to meet the walking conditions of the elderly people, the walking speed index from 20 to 89 years old was used, and the beats per minute (BPM) method was adopted considering the speed range for each age groups. The experiment was conducted with the assumption that the healthy people walked according to the BPM rhythm, and to apply the algorithm to the exoskeleton robot later, a full/individual dependent model was used by selecting a data collection method. Regarding the full dependent model as the representative model, the accuracy of classifying the stair terrains and level walking/ramp terrains is BPM 90: 98.74%, 95.78%, BPM 110: 99.33%, 95.75%, and BPM 130: 98.39%, 87.54%, respectively. The consumption times were 14.5, 21.1, and 14 ms according to BPM 90/110/130, respectively. LMR algorithm that satisfies the high classification accuracy according to walking speed has been developed. In the future, the LMR algorithm will be applied to the actual hip exoskeleton robot, and the gait phase estimation algorithm that estimates the user’s gait intention is to be combined. Additionally, when a user wearing a hip exoskeleton robot walks, we will check whether the combined algorithm properly supports the muscle strength.
An MPTCP-Based Transmission Scheme for Improving the Control Stability of Unmanned Aerial Vehicles
Authors: Lee Woonghee , Lee Joon Yeop , Joo Hyeontae , Kim Hwangnam
Published: April 2021

Recently, unmanned aerial vehicles (UAVs) have been applied to various applications. In order to perform repetitive and accurate tasks with a UAV, it is more efficient for the operator to perform the tasks through an integrated management program rather than controlling the UAVs one by one through a controller. In this environment, control packets must be reliably delivered to the UAV to perform missions stably. However, wireless communication is at risk of packet loss or packet delay. Typical network communications can respond to situations in which packets are lost by retransmitting lost packets. However, in the case of UAV control, delay due to retransmission is fatal, so control packet loss and delay should not occur. As UAVs move quickly, there is a high risk of accidents if control packets are lost or delayed. In order to stably control a UAV by transmitting control messages, we propose a control packet transmission scheme, ConClone. ConClone replicates control packets and then transmits them over multiple network connections to increase the probability of successful control packet transmission. We implemented ConClone using real equipment, and we verified its performance through experiments and theoretical analysis.
Memory-Replay Knowledge Distillation
Authors: Wang Jiyue , Zhang Pei , Li Yanxiong
Published: April 2021

Knowledge Distillation (KD), which transfers the knowledge from a teacher to a student network by penalizing their Kullback–Leibler (KL) divergence, is a widely used tool for Deep Neural Network (DNN) compression in intelligent sensor systems. Traditional KD uses pre-trained teacher, while self-KD distills its own knowledge to achieve better performance. The role of the teacher in self-KD is usually played by multi-branch peers or the identical sample with different augmentation. However, the mentioned self-KD methods above have their limitation for widespread use. The former needs to redesign the DNN for different tasks, and the latter relies on the effectiveness of the augmentation method. To avoid the limitation above, we propose a new self-KD method, Memory-replay Knowledge Distillation (MrKD), that uses the historical models as teachers. Firstly, we propose a novel self-KD training method that penalizes the KD loss between the current model’s output distributions and its backup outputs on the training trajectory. This strategy can regularize the model with its historical output distribution space to stabilize the learning. Secondly, a simple Fully Connected Network (FCN) is applied to ensemble the historical teacher’s output for a better guidance. Finally, to ensure the teacher outputs offer the right class as ground truth, we correct the teacher logit output by the Knowledge Adjustment (KA) method. Experiments on the image (dataset CIFAR-100, CIFAR-10, and CINIC-10) and audio (dataset DCASE) classification tasks show that MrKD improves single model training and working efficiently across different datasets. In contrast to the existing fancy self-KD methods with various external knowledge, the effectiveness of MrKD sheds light on the usually abandoned historical models during the training trajectory.
Optimal Energy Management Framework for Truck-Mounted Mobile Charging Stations Considering Power Distribution System Operating Conditions
Authors: Jeon Soi , Choi Dae-Hyun
Published: April 2021

A high charging demand from many electric vehicles (EVs) at a fixed charging station (FCS) with a limited number of charging poles can increase the waiting time of EVs and yield an abnormal power grid condition. To resolve these challenges, this paper presents an optimization framework in which a mobile charging station (MCS) is dispatched to the overloaded FCS to reduce the number of waiting EVs while maintaining normal power grid operation. Compared to existing MCS scheduling methods that do not consider actual power distribution system operations, the proposed framework takes into account the (i) active/reactive power flow and consumption of EVs, (ii) reactive power capability of MCS, and (iii) voltage quality in power distribution systems. In coupled transportation and power distribution systems, the proposed algorithm conducts optimal operation scheduling of MCS for both road routing and charging and discharging, thereby leading to the reduction of waiting EVs within the allowable voltage range. The proposed MCS optimization algorithm was tested in IEEE 13-bus and 33-bus distribution systems coupled with 9-node and 15-node transportation systems, respectively. The test results demonstrate the effectiveness of the proposed algorithm in terms of number of waiting EVs, voltage magnitude deviation, and reactive power of the MCS.
Influence of Bearing on Pier Failure Considering the Separation Condition under Near-Fault Earthquake
Authors: An Wenjun , Song Guquan
Published: April 2021

To study the influence of the near-fault vertical earthquake, the beam-spring-damper-pier model is used to simulate the double-span continuous beam bridge. The transient wave function expansion method and the indirect mode function method are used to calculate the seismic response of the bridge. The theoretical solutions of the contact force and displacement response of the bridge under vertical earthquake excitation near-fault are derived. By using piers with three different heights, the influence of vertical separation on pier-bending failure is analyzed reasonably. The results show that under the near-fault earthquake action, the split has a certain influence on the pier failure. Moreover, the stiffness and damping of the bearing have an influence on the pier failure, and the change of the maximum pier height has different effects. Therefore, for bridges of different sizes, it is of great significance to select the appropriate stiffness and damping bearings to reduce pier failure.
Performance Analysis of Wireless Local Area Network for a High-/Low-Priority Traffic Ratio at Different Numbers of Access Categories
Authors: Obelovska Kvitoslava , Panova Olga , Karovič Vincent
Published: April 2021

The performance of Wireless Local Area Network (WLAN) is highly dependent on the processes that are implemented in the Medium Access Control (MAC) sublayer regulated by the IEEE 802.11 standard. In turn, various parameters affect the performance of the MAC sublayer, the most important of which is the number of stations in the network and the offered load. With the massive growth of multimedia traffic, research of the network performance depending on traffic types is relevant. In this paper, we present the impact of a high-/low-priority traffic ratio on WLAN performance with different numbers of access categories. The simulation results show different impact of high-/low-priority traffic ratio on the performance of the MAC sublayer of wireless LANs depending on different network-sizes and on network conditions. Performance of the large network with two access categories and with the prevalent high-priority traffic is significantly higher than in the case of using four categories on the MAC sublayer. This allows us to conclude that the performance improvement of the large network with the prevalent high-priority traffic can be achieved by an adaptive adjustment of the access categories number on the MAC sublayer.
Removal of Antibiotics and Nutrients by Vetiver Grass (Chrysopogon zizanioides) from a Plug Flow Reactor Based Constructed Wetland Model
Authors: Panja Saumik , Sarkar Dibyendu , Zhang Zhiming , Datta Rupali
Published: April 2021

Overuse of antibiotics has resulted in widespread contamination of the environment and triggered antibiotic resistance in pathogenic bacteria. Conventional wastewater treatment plants (WWTPs) are not equipped to remove antibiotics. Effluents from WWTPs are usually the primary source of antibiotics in aquatic environments. There is an urgent need for cost-effective, environment-friendly technologies to address this issue. Along with antibiotics, nutrients (nitrogen and phosphorus) are also present in conventional WWTP effluents at high concentrations, causing environmental problems like eutrophication. In this study, we tested vetiver grass in a plug flow reactor-based constructed wetland model in a greenhouse setup for removing antibiotics ciprofloxacin (CIP) and tetracycline (TTC), and nutrients, N and P, from secondary wastewater effluent. The constructed wetland was designed based on a previous batch reaction kinetics study and reached a steady-state in 7 days. The measured concentrations of antibiotics were generally consistent with the modeling predictions using first-order reaction kinetics. Vetiver grass significantly (p < 0.05) removed 93% and 97% of CIP and TTC (initial concentrations of 10 mg/L), simultaneously with 93% and 84% nitrogen and phosphorus, respectively. Results show that using vetiver grass in constructed wetlands could be a viable green technology for the removal of antibiotics and nutrients from wastewater.
The Impact of Shape-Based Cue Discriminability on Attentional Performance
Authors: Lukashova-Sanz Olga , Wahl Siegfried , Wallis Thomas S. A. , Rifai Katharina
Published: April 2021

With rapidly developing technology, visual cues became a powerful tool for deliberate guiding of attention and affecting human performance. Using cues to manipulate attention introduces a trade-off between increased performance in cued, and decreased in not cued, locations. For higher efficacy of visual cues designed to purposely direct user’s attention, it is important to know how manipulation of cue properties affects attention. In this verification study, we addressed how varying cue complexity impacts the allocation of spatial endogenous covert attention in space and time. To gradually vary cue complexity, the discriminability of the cue was systematically modulated using a shape-based design. Performance was compared in attended and unattended locations in an orientation-discrimination task. We evaluated additional temporal costs due to processing of a more complex cue by comparing performance at two different inter-stimulus intervals. From preliminary data, attention scaled with cue discriminability, even for supra-threshold cue discriminability. Furthermore, individual cue processing times partly impacted performance for the most complex, but not simpler cues. We conclude that, first, cue complexity expressed by discriminability modulates endogenous covert attention at supra-threshold cue discriminability levels, with increasing benefits and decreasing costs; second, it is important to consider the temporal processing costs of complex visual cues.

Authors: Gerdt A.M. , Shutov A.M. , Belova L.A. , Gubareva E.A.
Published: April 2021

The development of acute kidney injury (AKI) in stroke patients is associated with an increase in hospital mortality, period of hospital treatment, disability, and economic health costs. At the same time, the influence of AKI on long-term stroke outcomes remains unclear.
The aim of the study was to determine the prognostic value of acute kidney damage in stroke patients.
Materials and Methods. The authors examined 272 stroke patients. Acute kidney damage was established according to the KDIGO recommendations (2012). Mortality of stroke patients during hospital treatment was 20.6 %. The prospective follow-up of stroke patients discharged from the hospital was 12 months.
Results. Acute kidney injury was diagnosed in 89 (32.7 %) stroke patients. After discharging from the hospital, 45 (20.8 %) patients died within 12 months. The relative risk of death within 12 months after stroke in the group of AKI patients was 3.7 (95 % CI 2.2–6.2, p<0.001) if compared with patients without AKI.
Multivariate analysis did not show any independent statistically significant correlation between AKI history and patients’ death within 12 months after hemorrhagic stroke. However, such a correlation was evident in ischemic stroke.
Conclusions. Acute kidney injury, developed in the acute period, increases the 12-month mortality in ischemic stroke patients.
Keywords: prognosis, stroke, acute kidney injury.

Целью исследования явилось определение прогностического значения острого повреждения почек у больных с инсультом.
Материалы и методы. Обследовано 272 больных с инсультом. Острое повреждение почек устанавливали согласно «Рекомендациям KDIGO» (2012). Летальность у больных с инсультом в период стационарного лечения составила 20,6 %. Срок проспективного наблюдения за больными инсультом, выписанными из стационара, составил 12 мес.
Результаты. Острое повреждение почек было диагностировано у 89 (32,7 %) больных инсультом. За 12 мес. наблюдения за больными, выписанными из стационара, умерло 45 (20,8 %) пациентов. Относительный риск смерти в течение 1-го года после инсульта в группе больных с ОПП составил 3,7 (95 % ДИ 2,2–6,2, p<0,001) в сравнении с больными без ОПП.
Независимая статистически значимая связь между ОПП в анамнезе и летальным исходом в течение года после геморрагического инсульта в многофакторном анализе не прослеживалась, в отличие от ишемического инсульта.
Выводы. Острое повреждение почек, развившееся в остром периоде, повышает годичную летальность у больных с ишемическим инсультом.
Ключевые слова: прогноз, инсульт, острое повреждение почек.

Published: April 2021

Management of patients with open diaphyseal fractures of the lower leg remains an urgent problem in traumatology and orthopedics.
The aim of the study is to improve the results of surgical treatment of patients with open lower leg injuries by means of disease management.
Materials and methods. The study under consideration was both retrospective and prospective. It included 67 patients with open lower leg injuries. The patients were divided into 3 groups depending on the fracture type and treatment modality.
Results. The two-stage modality of surgical treatment of open lower leg fractures (types 1 and 2) made it possible to significantly shorten the time frame compared to the period of treatment in patients with open lower leg fractures with installation of the external fixator. Active surgical modelling of the open diaphyseal fractures of the lower leg reduced the purulent complications from 60 % to 11 %.
Conclusion. In the case of an open lower leg fracture (type 1) blocking internal fixation is desirable, whereas in the case of open lower leg fractures (types 2, 3A and 3B) external fixation is preferable. In patients with open injuries (types 2 and 3A) two-stage fixation of bone fragments using external fixation with subsequent transition to internal one can be suggested.

Entre France et Angleterre : Jean IV, duc de Bretagne, et la signature
Authors: JEAY Claude
Published: April 2021

Jean IV (1365-1399) est le premier duc de Bretagne à avoir apposé sa signature sur un document. Ce geste matérialisé sur le papier ou le parchemin n’est pas le fruit du hasard. Le duc se met à signer après le roi de France, mais avant le roi d’Angleterre. Tous inventent leur propre signature dans le contexte politique troublé de la guerre de Cent Ans. Pour le roi de France, la signature contribue à consolider une légitimé contestée de toutes parts, aux côtés du portrait, de l’emblématique et de l’héraldique. Le duc de Bretagne est confronté à des difficultés de même ordre et prend la plume à son tour pour promouvoir sa qualité et son rang de prince grâce notamment à la formule De par le duc,

scandant d’un document à l’autre un titre encore fragile. Jean IV crée ainsi une signature originale, inédite, sorte de signature-souscription révélatrice de la position des ducs de Bretagne sur l’échiquier politique, entre les royaumes de France et d’Angleterre. Choisir sa signature et signer sont de véritables actes politiques.
La robe entre deux chaires : la famille Arnauld, du calvinisme au jansénisme

La famille Arnauld, rendue célèbre par des personnalités d’exception (la mère Angélique abbesse de Port-Royal, le Grand Arnauld, le ministre Simon Arnauld de Pomponne) a été partagée, comme tant d’autres, entre les trois grandes composantes du paysage religieux français au XVIIe siècle : protestantisme, jansénisme et catholicisme romain. Écartelée entre son idéal spirituel et son ambition politique au service de la monarchie et de l’État (tant auprès de Sully sous Henri IV qu’au Conseil d’En haut sous Louis XIV), elle a réussi à maintenir de génération en génération sa solidarité et sa cohésion, y compris sur le plan des enjeux financiers, matrimoniaux et sociaux, dans une commune adhésion à la doctrine augustinienne.

L’Institut d’art et d’archéologie de Paris dispose d’une collection d’antiquités grecques naguère constituée et exposée en Sorbonne. Composée d’environ 300 pièces, cette collection est aujourd’hui placée au coeur d’un programme de valorisation scientifique et pédagogique du patrimoine universitaire. Cette première étude concerne la céramique grecque, soit 164 vases ou fragments. Elle porte plus spécifiquement sur l’histoire de la constitution de la collection entre 1890 et 1921 au sein de l’Université de Paris. Afin de retracer l’origine de ces pièces, une double enquête a été menée, d’une part, à travers un examen attentif des marquages et, d’autre part, par une étude des décrets de dépôt et autres documents administratifs d’archives. Dans une seconde partie, nous discutons la question des envois pédagogiques de l’État et leur utilisation en Sorbonne puis à l’Institut d’art et d’archéologie au service de l’enseignement de l’archéologie grecque.
Les maîtres parisiens et les Juifs (fin XIIIe siècle) : perspectives nouvelles sur un dossier d’avis concernant le regimen Iudaeorum
Authors: Dorin Rowan
Published: April 2021

Vers 1270, une femme noble écrivit à Thomas d’Aquin, à Jean Peckham et à un juriste anonyme pour leur demander conseil sur le bon gouvernement de ses sujets et des Juifs. Savoir si la correspondante était une duchesse de Brabant ou la comtesse de Flandres a fait débat, de même que la datation des trois réponses et les relations qui pouvaient les unir. Comparant à nouveaux frais ces trois textes, cet article démontre que la correspondante ne demandait pas conseil sur les meilleures modalités de gouvernement des Juifs déjà installés dans ses territoires, mais au contraire sur la possibilité d’accueillir de nouvelles installations juives. Cette relecture identifie avec certitude l’auteur des lettres comme Marguerite de Constantinople, comtesse de Flandres et apporte un nouvel éclairage sur les politiques menées à l’égard de la présence des Juifs dans le nord-ouest de l’Europe dans les dernières décennies du XIIIe siècle.

Mirjaqıp Duwlatov hem Kazak edebiyatının hem de Kazak siyasi hayatının önemli simalarından biridir. İlk eserlerini 20. yüzyılın başında veren Mirjaqıp Duwlatov’un eserlerinde iki farklı dil kullanımı görülmektedir. Birincisi Duwlatov ile aynı dönemde eser veren bazı müelliflerin eserlerinde görülen kitabi dil; ikincisi ise Kazak konuşma diline dayanan dildir. Kitabi dil olarak adlandırılan dil, esasen Türkistan coğrafyasının ortak yazı dili ile Kazak lehçesinin karışımı ile oluşan edebî dildir. Duwlatov roman, tiyatro, şiir, hikâye türünde verdiği eserlerde kitabi dili kullanır. Gazete yazılarında, okul kitaplarında ve tercümelerinde ise halkın konuştuğu dili tercih eder. Mirjaqıp Duwlatov’un ve onunla aynı dönemde eser veren bazı müelliflerin edebi eserlerinde görülen kitabi dil, çağdaş Kazak Türkçesinden farklı özellikler göstermektedir. Bu özellikleri şu üç grupta sıralamak mümkündür: 1. Fonetik özellikler, 2. Morfolojik özellikler, 3. Söz varlığı.Bu çalışmada Duwlatov’un eserlerinde mevcut olan ancak çağdaş Kazak Türkçesinde bulunmayan morfolojik özellikler ele alınmıştır. Çağdaş Kazak Türkçesinde görülmeyen ekler, yapılar ve bağımlı biçimbirim ile bağımsız biçim birim arasında kalan edatlar ve zamirler değerlendirmeye alınmıştır.

Gramerleşme bir dile ait sözcüklerin kendi anlamlarını kaybederek birtakım gramatikal işlevler kazandığı süreci ifade etmektedir. Dilde yer alan adlar tarihî süreç içerisinde edatlara veya durum eklerine dönüşebilir. Türkçede fiil çekiminde kullanılan ve zamir kökenli şahıs ekleri diye adlandırılan şahıs eklerinin şahıs zamirlerinden kısalması bunun bir örneğidir. Bağımsız sözlük anlamına sahip fiiller de kendi anlamlarını kaybederek yardımcı fiil işleviyle kullanılabilir. Eski Türkçe döneminden itibaren bunun örnekleri karşımıza çıkmaktadır. Yardımcı fiil özelliği kazanan bir fiilin zaman içerisinde zaman veya kip ekine veya bir fiilimsi ekine dönüşmesi de söz konusudur. “Ayağa kalkmak” anlamındaki tur- fiili, henüz Eski Türkçe döneminde bağımsız bir sözlük unsuru olmaktan çıkmış yardımcı fiil işlevi kazanmıştır.Yine Eski Türkçe döneminde bağımsız sözlük anlamını kaybedip yardımcı fiil olarak kullanılmaya başlayan bir başka fiil de yat- fiilidir. Günümüz Kuzeybatı (Kıpçak) grubu Türk lehçelerinde cat- ve jat- biçiminde de geçen bu fiil, yardımcı fiil işlevinin yanı sıra zaman ifade eden, sıfat-fiil ve zarf-fiil özelliği gösteren ve cümlenin anlamını pekiştiren birtakım yapılarda karşımıza çıkmaktadır.

Published: April 2021

The construction of ionic conductive hydrogels with high transparency, excellent mechanical robustness, high toughness, and rapid self-recovery is highly desired yet challenging. Herein, a hydrogen-bonding network densification strategy is presented for preparing a highly stretchable and transparent poly(ionic liquid) hydrogel (PAM-r-MVIC) from the perspective of random copolymerization of 1-methyl-3-(4-vinylbenzyl) imidazolium chloride and acrylamide in water. Ascribing to the formation of a dense hydrogen-bonding network, the resultant PAM-r-MVIC exhibited an intrinsically high stretchability (>1000%) and compressibility (90%), fast self-recovery with high toughness (2950 kJ m
-3
), and excellent fatigue resistance with no deviation for 100 cycles. Dissipative particle dynamics simulations revealed that the orientation of hydrogen bonds along the stretching direction boosted mechanical strength and toughness, which were further proved by the restriction of molecular chain movements ascribing to the formation of a dense hydrogen-bonding network from mean square displacement calculations. Combining with high ionic conductivity over a wide temperature range and autonomous adhesion on various surfaces with tailored adhesive strength, the PAM-r-MVIC can readily work as a highly stretchable and healable ionic conductor for a capacitive/resistive bimodal sensor with self-adhesion, high sensitivity, excellent linearity, and great durability. This study might provide a new path of designing and fabricating ionic conductive hydrogels with high mechanical elasticity, high toughness, and excellent fatigue resilience for skin-inspired ionic sensors in detecting complex human motions.

Статья представляет опыт изучения мелодического motto григовской музыки в качестве скрытого музыкально-исторического символа. Автор прослеживает, как мелодический мотив, который норвежский композитор и музыковед Д. М. Юхансен назвал «григовским лейтмотивом» («Griegske ledemotiv»), воплощает композиционно-технические устремления не одного только Грига, но многих композиторов его времени. В основе статьи лежат наблюдения автора над влиянием эстетических, композиционно-практических и музыкально-научных идей прошлого на восприятие и понимание содержания музыки.

The article is an attempt to present a motivic motto of Edvard Grieg's music as a hidden symbol in the history of Western music. The author investigates how this melodic unit, defined as “Grieg's leitmotif” (“Griegske ledemotiv”) by the Norwegian composer and musicologist D. M. Johansen, embodies tonal pursuits, as well as harmonic and formal ones, within not only Grieg's output, but with various composers of his time. The article is based on observations on how some aesthetic, compositional and scholarly procedures of the past influenced on reception and comprehension of musical substance.

Published: April 2021

This research document shows the development of an application implemented in the humanoid robot NAO H25, using the methodology of Analysis, Design, Development, Implementation and Evaluation (ADDIE). Currently, in most public institutions of basic education, there is no robotic technology that the teacher uses for teaching a particular subject. The purpose of the application is that it works as a didactic resource, with which teachers and students of basic education can use as a form of support for the teaching of the multiplication operation. This application is capable of making the NAO H25 robot explain the multiplication operation in an arithmetic way and carry out its verification by means of the Mayan method. When the application is implemented in the NAO H25 robot, it acts as a trainer in the topic of multiplications, following a didactic sequence as a form of support for the development of the explanation. For the moment, tests were carried out on a group of 32 students of the computer engineering degree at this university centre. Where it was found that 94% were interested in the robot acting as a capacitor. 97% would like more applications of this type to be made for learning other subjects. The development of the application is with the motive of obtaining a significant learning in the students of third year of basic education, fomenting the interest by the technology.

The energy reform promotes the use of renewable energies to face the reduction of fossil energy consumption. Michoacán is a state where agriculture proliferates, counting on a diversity of climates that favors the cultivation of a significant variety of fruits, in addition that its harvest area is abundant. On many occasions the waste generated from the harvest represents a problem for the farmers, because the volume is too much and they do not know what to do, unfortunately they opt by the illegal burning. However, biomass can be used as fuel with high thermal outputs, with a lower cost than other fuels, which represents an alternative for many industries that require combustion in their processes. Michoacán stands out continuously at the first places in the production of diverse fruts at national level, but its residues are used only for cattle consumption, so this research work not only takes into account the net harvest, it also makes an estimate of effective waste that can be considered biomass available for use in thermal processes, indicating according to its calorific value the energy potential wasted until the moment.
