Aerial Forest Fire Detection and Monitoring Using a Small UAV
Authors: Vasconcelos Reinolds de Sousa Joaquim , Vieira Gamboa Pedro 
Published: June 2020

In recent years, large patches of forest have been destroyed by fires, bringing tragic consequences for the environment and small settlements established around these regions. In this context, it is essential that fire fighting teams possess an increased situational awareness about the fire propagation, in order to promptly act in the extinguishing process. Recent advances in UAV technology allied with remote sensing and computer vision techniques show very promising UAVs applicability in forest fires detection and monitoring. Besides presenting lower operational costs, these vehicles are able to reach regions that are inaccessible or considered too dangerous for fire fighting crews operations. This paper describes the application of a real-time forest fire detection algorithm using aerial images captured by a video camera onboard an Unmanned Aerial Vehicle (UAV). The forest fire detection algorithm consists of a rule-based colour model that uses both RGB and YCbCr colour spaces to identify fire pixels. An intuitive targeting system was also developed, allowing the detection of multiple fires at the same time. Additionally, a fire geolocation algorithm was developed in order to estimate the fire location in terms of latitude (φ), longitude (λ) and altitude (h). The geolocation algorithm consists of applying two coordinates systems transformations between the body-fixed frame, North-East-Down frame (NED) and Earth-Centered, Earth Fixed (ECEF) frame. Flight tests were performed during a controlled burn in order to assess the fire detection algorithm performance. The algorithm was able to detect the fire with few false positive detections.

Published: June 2020

In the past few years there has been a significant growth of the elderly population in both developing and developed countries. This event provided new economic, technical and demographic challenges to current societies in several areas and services. Among them the healthcare services can be highlighted, due to its impact in people daily lives. As a natural response an effort has been made by both the scientific and industrial community to develop alternatives, which could mitigate the current healthcare services bottlenecks and provide means in aiding and improve the end-user life quality. Through a combination of information and communication technologies specialized ecosystems have been developed, however multiple challenges arose, which compromise their adoption and acceptance among the main stakeholders, such as their autonomy, robustness, security, integration, human-computer interactions and usability. As consequence an effort has been made to deal with the technical related bottlenecks, which shifted the development process focus from the end-user to the ecosystems technological impairments. Despite there being user related issues, such as usability, which still remains to be addressed. Therefore this article focuses over the ecosystem’s usability through the analysis of the process used to check the ecosystem’s compliance level with the usability guidelines from Jakob Nielsen and Shneiderman; and the identification of the quantifiable parameters for each principle that could aid in the heuristics evaluation process by maximizing its objectivity improve its overall accuracy.

Published: June 2020

Self-compacting concretes represent a new advance for concrete construction because they offer many advantages from the economic, technical and social point of view. They are very fluid concretes, which are put in place without vibration. When pouring into a formwork, tightening a BAP is ensured by the simple effect of gravity. Thanks to their formulation, they offer exceptional flow characteristics and filling formwork while resisting perfectly segregation. Homogeneous and stable, they have resistances and durability similar to those of traditional concretes of which they are differentiated by their properties in the fresh state. The use of self-compacting concrete reduces the noise nuisance, as well as the hardness of the work. This research work is part of a policy of contributing to the improvement of the properties of self-compacting concretes prepared from local materials in the M’sila region. In this study, we are interested in obtaining the most suitable concrete formulation for the different local materials of the M’sila region. Our study is directed towards the effect of the following parameters on the physico-mechanical properties of the composite such as: dynamic segregation, spreading diameter as well as mechanical strengths (compression, traction). It is therefore a question of determining the criteria to be imposed on these parameters, in order to lead to the construction of a self-compacting concrete characterized by an acceptable resistance. The experimental results of compressive strengths show significant behaviors between BAP and BV. They allowed to distinguish a resistance gain between 15.11 and 49.28, this gain is explained by a rehydration of the cement matrix due to the migration of the water through the pores for the BAP, but also to better binding properties of the hydrates forms.

Published: June 2020

The skeletal muscle activation generates electric signals called myoelectric signals. In recent years a strong scientific activity has been developed in the recognition of limb movements from electromyography (EMG) signals recorded from non-invasive (surface) electrodes, in order to design systems for prosthetic control. Surface EMG acquire the activation of surrounding muscles and for that reason the obtained signal needs to be conditioned and processed, with pattern recognition techniques for extraction and classification. In this work EMG signals were acquired for two hand movements, “hand close” and “hand open”. The EMG electrodes were placed on the forearm and positioned over the extensor digitorum muscle, for the “hand open” and flexor digitorum muscle, for the “hand close”. Using MATLAB software the signal conditioning, feature extraction and classification were performed. The feature extraction process was carried with the Wavelet Packet Transform (WPT) technique and the classification process was done with two different techniques for comparison purposes, Neural Networks (NN) and Support Vector Machines (SVM). The results show that the SVM classifier used presented better classification performance compared to NN classifier used.

Published: June 2020

Photovoltaic (PV) energy has been asserting itself in recent years as a true alternative for the electricity production in the future. It is well known that the accuracy of PV parameters is crucial to achieving optimal control of PV systems under any operating conditions. Although many attempts have been made to study the operating ranges of PV parameters, this remains a current research topic given the diversity of PV technologies. In this paper, the PV parameters variation with irradiance and temperature levels is experimentally analysed for a polycrystalline (poly-Si) silicon PV module. The experiment considers experimental data from 130 I-V characteristic curves measured over a typical day, considering several irradiance and temperature levels in the range 29–1023 W/m2 and 19–68 °C, respectively. The results show that PV parameters vary considerably with irradiance and temperature levels for poly-Si technology.

Authors: DISEMADI HARI SUTRA , PRANANINGTYAS PARAMITA 
Published: June 2020

<p>Globalization era requires Indonesia to always use technology and information in improving economy. This also applies to insurance companies that have implemented technology and information. Conventional insurance has developed into online one that attracts Indonesian citizen. However, today new issue is about protecting the spiritual rights of consumers as well as the halal or haram of online insurance. Answering this problem, this research will use normative juridical (doctrinal) method that prioritizes primary legal material i.e. insurance laws, consumer protection laws, and other legal materials. This research shows the existence of online insurance in Indonesia which rapidly develops because it offers more conveniences compared to conventional one. In Islamic law, online insurance is allowed as long as it is in line with Islamic law principles in protecting consumers’ spiritual rights. The example of sharia principle is cooperation by paying tabarru’ funds, using tabarru’ and tijarah agreement, and sharing similar responsibility between one participant and others (ta’awun). The legal basis for insurance in Indonesia is contained in the 2014 Law Number 40 and MUI Fatwa Number 21/DSN-MUI/X/2001.</p><p>Era globalisasi mengharuskan Indonesia untuk selalu memanfaatkan teknologi dan informasi dalam meningkatkan perekonomian.

Namun, persoalan yang hangat dibicarakan saat ini mengenai perlindungan hak spiritual konsumen serta halal atau haramnya asuransi online. Untuk menjawab persoalan tersebut, penelitian ini menggunakan metode yuridis normatif (doktrinal) yang mengedepankan bahan hukum primer yaitu undang-undang perasuransian, undang-undang perlindungan konsumen, serta bahan hukum lain. Penelitian ini menunjukan eksistensi asuransi online di Indonesia telah mengalami perkembangan pesat karena memberikan kemudahan dibanding asuransi konvensional. Dalam hukum Islam, asuransi online pada dasarnya diperbolehkan dengan syarat tidak bertentangan dengan prinsip-prinsip hukum Islam dalam melindungi hak spiritual konsumen. Contohnya prinsip syariah tersebut seperti bekerja sama dengan cara masing-masing mengeluarkan dana tabarru’, menggunakan akad tabarru’ dan akad tijarah, dan saling menanggung risiko antara satu peserta dengan peserta lainnya (ta’awun). Dasar hukum mengenai asuransi di Indonesia terdapat dalam UU Nomor 40 Tahun 2014 dan Fatwa MUI Nomor: 21/DSN-MUI/X/2001.</p>

Abstract
Background: P53 pathway inactivation plays an important role in the process of breast cancer tumorigenesis. Post-translational protein modification abnormalities have been confirmed to be an important mechanism underlying inactivation of p53. Numerous deubiquitinating enzymes are aberrantly expressed in breast cancer, and a few deubiquitination enzymes can deubiquitinate and stabilize p53. Here, we report that ovarian tumor (OTU) deubiquitinase 3 (OTUD3) is a deubiquitylase of p53 in breast carcinoma (BC).Methods: Correlations between the mRNA expression levels of OTUD3, TP53 and PTEN and the prognosis of BC were assessed with the Kaplan-Meier Plotter tool. OTUD3 protein expression in 80 pairs of specimens in our cohort was examined by immunohistochemistry and western blotting. The relationship among OTUD3, p53, and p21 proteins was analyzed. Half-life analysis and ubiquitylation assay were performed to elucidate the molecular mechanism by which OTUD3 stabilizes p53. The interaction between OTUD3 and p53 in BC cells was verified by a co-immunoprecipitation assay and GST pulldown experiments. MTS assay for proliferation detection, detection of apoptosis induced by cisplatin and colony formation assay were employed to investigate the functional effects of OTUD3 on breast cancer cells. Results: OTUD3 downregulation is correlated with a poor prognosis in BC patients. OTUD3 expression is decreased in breast cancer tissues and not associated with the histological grade. OTUD3 also inhibits cell proliferation and clone formation and increases the sensitivity of BC cells to apoptosis induced by chemotherapy drugs. Reduced OTUD3 expression accompanied by decreased p53 abundance is correlated with human breast cancer progression. Ectopic expression of wild-type OTUD3, but not its catalytically inactive mutant, stabilizes and activates p53. Mechanistically, OTUD3 interacts directly with p53 through the amino-terminal OTU region. Finally, OTUD3 protects p53 from murine double minute 2 (Mdm2)-mediated ubiquitination and degradation, enabling the deubiquitination of p53 in BC cells. Conclusions: In summary, we found that OTUD3 may be a potential therapeutic target for restoring p53 function in breast cancer cells and suggest that the OTUD3-p53 signaling axis may play a critical role in tumor suppression.
