Authors: Permana Randy , Eka Praja Wiyata Mandala  , Dewi Eka Putri
Published: June 2023

Augmented Reality (AR) is a digital technology that allows the creation of a combination between the real world and digital content projections to produce additional valuable information for users. This technology has begun to implement in various fields of human life like industry, health, military, entertainment, and education. AR technology will be applied to the education sector in this community service activity. This activity aims to introduce AR technology and a development model based on the Model Generate Target (MGT) to service partners, namely SMA INS Kayu Tanam. The Generate Target model is an AR application development concept by adopting the concept of Digital Twins, where digital content projections will be made similar to real objects. The projected digital content will serve as a descriptive object from the real world, so users can interact more flexibly with objects from the real world. The activity was carried out by providing an introduction to AR technology, installing AR design software, and practicing making simple AR applications using the MGT concept for partner service to the community. In this activity, the designed AR will use spherical objects in the real world and the resulting digital projection is a virus. Projection of digital content onto spherical objects will provide better information and learning experiences in viral object recognition because 3D objects will appear and be attached to real objects. The expected results of this community service activity are introducing AR technology to partners engaged in education and providing a new solution in implementing new digital content-based teaching media that can be applied to several subjects such as biology, chemistry, and glasses to community service partners.

Published: June 2023

For the purpose of orthodontic treatment of children with congenital cleft lip and palate, various orthodontic constructions are used. The use of removable appliances indicated for narrowing or shortening of the dental arches, anomalies of the individual teeth position. The question of determining the magnitude of force reactions around special devices (clasps) that are designed to fix appliances on teeth during treatment, under the conditions of the specificity of the development of the upper jaw and the impact of surgical interventions on it, requires detailing, which determined the purpose of this research. A three-dimensional 3D simulation model was created based on digital data of the spatial geometry of a sample of orthodontic appliance used for orthodontic treatment of children with congenital unilateral cleft lip and palate. Mathematical modeling methods were used to study the stress-deformed state of the appliance and estimate the magnitudes and distribution of the amplitudes of force reactions around its fasteners (clasps). Force reactions around of the supports of the orthodontic appliance when the screw is rotated from 0° to 360° (axial movement by 1 mm) are unevenly distributed, with a minimum value of force amplitudes of 10.3 N and a maximum of 30.9 N. It was noted that in the area of fasteners (clasps) placed more distally, the values are higher (30.9 N and 27.6 N) than in the medially placed fasteners (10.3 N and 12.5 N). It is also worth noting that on the side of the base of the appliance, which corresponds to the location of the small fragment of the jaw, the values of the force amplitudes are greater (30.9 N and 12.5 N) than on the side of the large fragment (27.6 N and 10.3 N). A significant dependence of the values of force reactions on the stiffness characteristics of the jaw and the type of force transmission from the orthodontic appliance to its areas was established.

Preservar para extrair, grilar e espoliar
Authors: Castriota Rodrigo
Published: June 2023

Unidades de conservação (UCs) tem diversas funções alternativas que excedem sua suposta finalidade original de preservar o meio ambiente. No caso da mineração, em particular, há uma grande diversidade de funções articuladas aos interesses das mineradoras. A partir do caso do “Mosaico de Carajás”, um conjunto de UCs no sudeste paraense, o presente artigo discute os diversos usos e funções para as operações da Vale S.A., chamando a atenção para suas intencionalidades subjacentes e formas institucionais de implementação. Três funções principais são destacadas: primeiro, o controle territorial através das UCs protege fisicamente os sítios de extração de ocupações e conflitos territoriais, viabilizando a operação mineradora; segundo, UCs regularizam operações ilegais de aquisição de terras e rodadas anteriores de grilagem, geralmente envolvendo a empresa mineradora; terceiro, a criação de novas UCS serve como instrumento de espoliação de grupos e comunidades assentadas, definindo novas funções e parâmetros legais de uso da terra. A partir da ideia de “operações do capital”, este artigo oferece o conceito de “ambientalismo operacional” para denotar as formas através das quais a regulação ambiental e as UCs se tornam elementos fundamentais para a mineração, em múltiplas instâncias.

Published: June 2023

A rápida expansão da Educação à Distância-EaD no Brasil tem provocado discussões acaloradas, que vão além daquelas relacionadas com os métodos de ensino e com a qualidade. A flexibilização observada para a oferta de cursos e a capilaridade desta modalidade tornaram a EaD uma alternativa para a ampliação do ensino superior. Um dos impactos do crescimento da EaD se dá na mobilidade espacial estudantil. O estado de Minas Gerais apresentou expressivo crescimento de matriculados na EaD, inclusive estando acima da taxa nacional no período de 2005 a 2019. Este trabalho se propõe a avaliar a expansão da oferta da educação superior a distância e a mobilidade pendular de estudantes para Belo Horizonte e para os cinco principais centros regionais do interior de Minas Gerais, considerando os fluxos identificados no Censo Demográfico de 2010. Os dados de matrículas, fluxos e distâncias conjugados com a identificação dos grandes eixos viários de Minas Gerais permitiram avaliar como Belo Horizonte e os outros cinco centros regionais exercem suas centralidades em relação à modalidade.

Published: June 2023

Rhombohedral Bi(Mg0.5Ti0.5)O3-modified BiFeO3-BaTiO3 ceramics were successfully textured along the nonpolar 〈100〉 direction using the templated grain growth process for the first time. The textured 0.90(0.33BaTiO30.67BiFeO3)0.10Bi(Mg0.5Ti0.5)O3 (33BTBF-10BMT) ceramics were fabricated by a 33BTBF-10BMT matrix with BT templates. The degree of orientation was investigated by various sintering temperatures, and the 80% oriented 33BTBF-10BMT along the 〈100〉 direction was achieved at a relatively high sintering temperature. However, the degree of orientation abruptly decreased at the highest sintering temperature of 1100 °C due to the large pores and low relative density. Based on the analysis of the unipolar strain measurements, the highest strain and d
33
* values were observed in the textured ceramics with 80% orientation. These textured ceramics exhibited approximately 0.3% strain and a d
33
* exceeding 400 pm V−1, representing approximately 1.5 times higher values compared to the nontextured ceramics.

Performance of a Multiuser Cooperative IoT NOMA Network with Battery-Assisted Energy Harvesting
Authors: AGRAWAL KAMAL , Jee Anand , Prakriya Shankar
Published: June 2023

This paper investigates a cooperative non-orthogonal multiple access (Co-NM) based network consisting of a multiantenna source, a full-duplex energy harvesting (EH) near user (NU) internet-of-things (IoT) node and multiple distant user (DU) IoT nodes. The source shares a direct link to the NU, while the NU augments the harvested energy by a limited amount of its battery energy to relay the information to the selected DU. Considering time-switching (TS) or power-splitting (PS) protocol, practical nonlinear EH, successive interference cancellation error, and opportunistic Co-NM/OMA (OM) switching, closed-form expressions are derived for the outage probability and throughput of both DU and NU. We demonstrate that the proposed opportunistic Co-NM/OM switching can ensure a performance similar to OM at the NU without loss in DU throughput. Also, a joint optimal choice of battery energy and PS/TS parameter helps in attaining a  maximum energy efficiency (EE). Moreover, Co-NM/OM switching ensures higher EE compared to Co-NM and OM. 
Deep Gaussian Process for Enhanced Bayesian Optimization and its Application in Additive Manufacturing
Authors: Gnanasambandam Raghav , Shen Bo , Law Andrew Chung Chee , Dou Chaoran , Kong Zhenyu
Published: June 2023

Engineering design problems typically require optimizing a quality measure by finding the right combination of controllable input parameters. In additive manufacturing (AM), the output characteristics of the process can often be non-stationary functions of the process parameters. Bayesian Optimization (BO) is a methodology to optimize such “black-box” functions, i.e., the input-output relationship is unknown and expensive to compute. Optimization tasks involving “black-box” functions widely use BO with Gaussian Process (GP) regression surrogate model. Using GPs with standard kernels is insufficient for modeling non-stationary functions, while GPs with non-stationary kernels are typically over-parameterized. On the other hand, a Deep Gaussian Process (DGP) can overcome GPs’ shortcomings by considering a composition of multiple GPs. Inference in a DGP is challenging due to its structure resulting in a non Gaussian posterior, and using DGP as a surrogate model for BO is not straightforward. Stochastic Imputation (SI) based inference is promising in speed and accuracy for BO. This work proposes a bootstrap aggregation based procedure to effectively utilize the SI-based inference for BO with a DGP surrogate model. The proposed BO algorithm DGP-SI-BO is faster and empirically better than the state-of-the-art BO method in optimizing nonstationary functions. Several analytical test functions and a case study in metal additive manufacturing simulation demonstrate the applicability of the proposed method.
Decoupling the Influence of Cell Proliferation and Migration in Wound Healing Assays by Combining Laser Direct Write Photoablation and Mathematical Modeling
Authors: Saksena Jayant , Alzoubi Madlin S. , Burow Matthew E. , Chrisey Douglas B.
Published: June 2023

Traditional in vitro scratch assays lack standardization due to poor control over wound geometry and fail to account for cell proliferation. Here, we developed a novel scratch assay that enables precise control over wound geometry using CAD/CAM laser photoablation and takes cell proliferation into consideration using a simple reaction-diffusion based mathematical model. We demonstrated that diffusivity in precisely photoablated cell layers serves as a more accurate measure of cell motility than the rate of gap closure. Further, we biologically validated this assay using cells harvested from patients and patient-derived xenografts to gain insights into the influence of the presence stromal cells on metaplastic and non-metaplastic triple negative breast cancer metastasis.
An Improved End-to-End Data Security Approach for Cloud Computing
Authors: Ghosh Soumalya , Verma Shiv Kumar , Ghosh Uttam
Published: June 2023

Cloud computing is one of the major cutting-edge technology which is in a gigantic growth to redefine the aspect of computation with its service-oriented computing. It has addressed the issue of owning and managing the computational infrastructure by provid- ing the service through a pay-and-use model as an ultimate consequence of saving money and time. However, the major hindrance can be security breaches, particularly when the sender uploads or receiver downloads the data from a remotely accessed server. A very generic approach to ensuring data security through different encryption techniques, but it might not be able to maintain the security standard. This paper proposed an end-to-end data security approach from sender side to receiver side by adding extra padding sequences, randomized salting followed by hashing and the encryption technique. The efficiency of the proposed approach is analyzed through both the simulated system and mathematical formulations with several performance metrics, like cipher text size, encryption and decryption time, encryption and decryption throughput. Further, the performances are compared with contem- porary algorithms and results have shown that the proposed algorithm creates a larger cipher text which is almost impossible to crack due to randomization modules. Though it has a significantly larger encryption and decryption time, as a consequence, lower throughput also. However, here our prime concern is ensuring security, not the time required to encrypt the text. 
Planning Dense Object Packing by Pushing Objects
Authors: Iwao Kazuki , Nishi Takao , Kiyokawa Takuya , Petit Damien , Wan Weiwei , Harada Kensuke
Published: June 2023

To realize a dense object placement into a container, we propose a robotic packing motion planner by pushing objects to the side of other objects. Our method comprises three planning strategies, i.e., object placement planning, robotic packing-action planning, and action sequence planning. Object placement planning generates objects’ placement into a container without gaps between objects. Based on the planned placement, the robotic packing-action planner selectively uses two action strategies where one is to directly place the object in the desired location of a container by using a pick-andplace approach, and the other is to first place the object at a certain distance from the surrounding object and then push it to achieve the placement without gaps. Finally, the action sequence planning plans the order of selected manipulation strategies. Through experiments, we confirmed that the robot efficiently packs multiple objects into a container by effectively using object pushing.
Towards Open Domain-Specific Recognition using Quad-Channel Self-Attention Reciprocal Point Learning and Autoencoder
Authors: Alfarisy Gusti Ahmad Fanshuri , Malik Owais Ahmed , Ong Wee-Hong
Published: June 2023

Open-Set Recognition (OSR) has been emphasizing its capability to reject unknown classes and maintain closed-set performance simultaneously. The primary objective of OSR is to minimize the risk of unknown classes being predicted as one of the known classes. The OSR assumes that unknown classes are present during testing and identifies only one distribution of the unknowns. On the other hand, recognizing unknowns in the domain of interest and outside of the domain of interest will benefit future learning endeavors. These rejected unknown samples in the domain of interest could be leveraged for the further development of deep learning models. We introduce and formalize the open domain-specific space risk to mitigate the recognition of two unknown distributions. To achieve the solution, we propose an initial baseline using quad-channel self-attention reciprocal point learning to mitigate open-space risk and autoencoder to mitigate open domain-specific space risk. We utilize the knowledge in pre-trained models and tune the open-set hyperparameter first before comparing it with other methods as a fair analysis. We also investigate the effect of different pre-trained models in achieving open-set performance. To validate our approach, we tested the model with various domains: garbage, vehicle, household items, and pets. The experimental results demonstrate that our method is robust in rejecting unseen classes while keeping the closed-set accuracy performance at bay. Furthermore, the autoencoder could potentially mitigate open domain-specific space risk in the future, and the determination of pre-trained models highly contributes to the open-set performance.

Sediaan Orally Disintegrating Tablet (ODT) merupakan sistem penghantaran obat dengan disintegrasi yang cepat dalam waktu kurang dari 60 detik. ODT umumnya menggunakan bahan penghancur yang dapat mempercepat hancurnya tablet dalam rongga mulut tanpa melalui proses pembentukan gel, antara lain crospovidone. Penelitian ini bertujuan mengetahui pengaruh penambahan crospovidone dalam pembuatan ODT loratadin dengan metode granulasi basah dan kempa langsung terhadap sifat fisik tablet, seperti kerapuhan, kekerasan, waktu pembasahan, waktu hancur serta profil disolusi tablet. Penambahan crospovidone dengan metode granulasi basah dilakukan secara intragranular dan ekstragranular. Secara intragranular crospovidone dicampurkan dengan eksipien lain untuk membentuk granul, sedangkan secara ekstragranular, crospovidone dicampurkan dengan granul kering. Berbeda dengan metode granulasi basah, pada metode kempa langsung, crospovidone dicampurkan langsung dengan bahan-bahan lainnya. Hasil penelitian menunjukan bahwa penambahan crospovidone dalam pembuatan ODT loratadin secara intragranular, ekstragranular dan kempa langsung mempengaruhi sifat fisik tablet seperti kerapuhan, kekerasan, waktu pembasahan, waktu hancur serta profil disolusi tablet. Penambahan crospovidone secara kempa langsung merupakan metode yang paling efektif dalam menghasilkan Orally Disintegrating Tablet loratadine dengan waktu hancur yang paling singkat yaitu 57 detik.

Published: June 2023

Em muitas licitações de obras de saneamento básico no Brasil ocorrem falhas e inconformidades, comprometendo a seleção de uma empresa para a execução da obra. Por isso o planejamento e a condução dos trâmites das fases Preliminar e Interna de uma licitação são de extrema importância, justificando a necessidade de uma ferramenta digital que permita minimizar os erros e as paralisações dos processos licitatórios, bem como depois, para que as obras não sejam comprometidas pela falta de planejamento. Este trabalho teve como objetivo desenvolver uma ferramenta digital para checagem de documentação, em suas etapas Preliminar e Interna, visando à publicação de licitações de obras de engenharia na área de saneamento básico. Como resultado, foi criado o LicitaScan. Em pesquisa com os usuários, foi relatado que, em linhas gerais, a ferramenta digital LicitaScan é útil e prática para utilização nos processos de contratações de obras na área de saneamento básico.

Authors: Berni De Marque Mário , Antônio Daniel Luiz
Published: June 2023

A eutrofização de recursos hídricos causada por lançamento de esgoto com compostos nitrogenados tem se tornado uma preocupação cada vez maior na área de saneamento. Desta forma, diversos sistemas de tratamento foram criados e estudados para promover a remoção de matéria orgânica e compostos nitrogenados de efluentes com baixa relação C/N – característico de esgoto sanitário e efluentes de tratamento anaeróbio – por meio de diferentes vias de conversão da amônia em gás nitrogênio. Assim, por meio de buscas em sites de pesquisas acadêmicas com palavras-chave do tema, esta revisão tem por objetivo descrever as principais vias de conversão de amônia em gás nitrogênio em sistemas de tratamento e levantar experiências e aplicações reais de 7 sistemas de tratamento diferentes, sendo eles: Modified Ludzack-Ettinger (MLE), Processo Wurmann (PW), University Cape Town (UCT), Bardenpho (BDP), Alimentação distribuída (AD), Nitrificação Parcial seguida de Anammox (NP-Amx) e Desnitrificação Parcial seguida de Anammox (DP - Amx). A análise dos diferentes estudos e aplicações demonstrou que a remoção de nitrogênio pode ser otimizada ao ajustar parâmetros de projeto e promover condições favoráveis aos microrganismos de interesse. Por fim, certos aspectos devem ser considerados na proposição de novos sistemas para remoção biológica de nitrogênio (RBN), como economia de energia, favorecimento das comunidades bacterianas de interesse, conciliar com a geolocalização dos sistemas e otimizar processos para serem operados de forma simples e eficaz.

Published: June 2023

The aim: Determination of the optimal method for surgical correction of stages C2-C6s varicose superficial veins.
Materials and methods: The treatment results of 228 patients with stages C2-C6 of primary varicose according to the CEAP classification using thermal and non-thermal treatment methods were analyzed.
Results: All patients underwent operations under the control of ultrasound scanning. In patients after EVLA, total trunk obliteration was detected in 148 patients (98.7%) after 1 week, and in 100% after a year. In 2 patients, reflux was diagnosed in the PDSV and in the ZDSV after 1 week. In patients after RFA, inflow reflux on the leg was in 1 patient (5.2%), in others - complete obliteration (18 patients - 94.7%). In patients after MOCA, recanalization was performed in 5 patients (19.2%) with a control ultrasound investigation after 1 month. In patients after cyanoacrylate obliteration, inflow reflux on the leg after 1 month was in 2 patients (14.2%). In patients who underwent UGS of the GSV trunk, 5 patients (33.3%) had persistence of pathological reflux after 1 month with control ultrasound. All corrections were performed using Foam form sclerotherapy.
Conclusions: EVLA is the most effective method of treating varicose veins and gives the best long-term results. The advantage of non-thermal methods is the lack of influence on paravenous structures and no need for tumescent anesthesia, which is important in case of an allergic history. After applying cyanoacry¬late, there is no need for mandatory compression. The advantage of foam scleroobliteration is its lowest cost among all methods. Foam sclerotherapy was the method of choice for correction of postoperative treatment.

Published: June 2023

The aim: To evaluate the effectiveness of treatment patients with spontaneous PLF and labyrinthine window ruptures by studying the clinical and audiological results.
Materials and methods: 52 patients after exposure to traumatic factors in the anamnesis were evaluated. The perilymphatic fistula was diagnosed in 18 patients after the complex examination. All patients with PLF underwent surgical treatment.
Results: Vestibular disorders and hearing loss were the predominant symptoms. The fistula test was positive in 11 (61%) patients. Fluctuating hearing loss was determined in 9 (50%) patients. Labyrinthine window ruptures were detected in 16 (88%) patients: oval window membrane rupture was identified in 6 patients, and in another 10 patients round window membrane rupture was found and was detected on CT scan. The surgical treatment included minimally invasive tympanotomy with combined microscopic and endoscopic visualization and sealing techniques. Results were evaluated in 6 months after surgical treatment, patients had a decrease in bone and air conduction thresholds at all evaluated frequencies and a significant decrease in the level of the air-bone interval.
Conclusions: Fluctuating hearing loss is considered one of the key symptoms, which suggests the presence of PLF. Determination of PLF and its surgical treatment, by using minimally invasive tympanotomy with sealing technique using optimal combined visualization, allows obtaining a stable functional result, with hearing improvement and vestibular symptoms reducing.
