Design and Development of an Internet of Things (IoT)-Based Anti-Theft System in Museum Cultural Relics Using RFID

Art colonnades and museums all over the world are the first option for individuals to visit for the enhancement of the cultural life of people. To ensure their safety, museums have established numerous cultural security measures. Traditional strategies do not obstruct their pace entirely. They only use a computer in the museum to check individuals at the entrance and exit. Therefore, the authors proposed a gallery anti-stealing device created on the internet-of-things (IoT) technology that ensures security through passive readers/writers of RFID. Radio frequency identification (RFID) remains a system that practices isolated data storing and recovery and offers object tracking with a unique identity code. The system then sends sound and light warning information, while the photographic camera structure is triggered to capture a picture at the same time. The recognition of the accuracy in the hardware component of the device can be additionally enhanced by the use of this technology to increase the safety of museum equipment.

Estimation of morphological characteristics of Seedlings of Genipa americana L. (Rubiaceae)

Genipa americana L. is a tree species with socioeconomic and environmental potential. Popularly known as jenipapeiro, it is used in the production of wood and its fruits are considered one of the main recipes of small farmers, being also used in the recovery of degraded areas. The work aimed to evaluate and compare the traditional method (Pachymeter) and digital image obtained through a photographic camera to determine the height of the plant, height of insertion of the first leaf and diameter of the neck of American genipa. The study was carried out in the Flora-action-Seedlings nursery and in the Didactics II laboratory. In the nursery, 30 seedlings were analyzed randomly. In the same numerical sequence were the seedlings on the phenotyping platform where the images were captured, with a Sony Gps Hd Avchd progressive digital camera, attached at a height of 50 cm. The diameter of the stem (CD), the total height of the plant and the height of insertion of the last leaf were measured using the free ImageJ software, using images from digital cameras. Statistical analyzes were performed with the aid of the Sigmaplot program and analyzed using descriptive statistics to estimate measures of central tendency (mean) and dispersion (standard deviation and coefficient of variation). Through the results, it is possible to observe the high proportion of the two methodologies, being validated both for the traditional methods (caliper) and for the innovative method (digital image). Where the coefficients were high, showing the accuracy of the methods. Thus, it indicates that the digital camera can be very useful to measure the total height of a plant and can also be indicated for trees, shrubs and others. According to the data obtained, it can be said that there is precision between the methodologies used with manual measurement and digital images, using the ImageJ software, and its use is recommended for the analysis of the morphological characteristics of the species Genipa americana L.

Evaluation of 2 Low-cost High-definition Video Systems for Venous Anastomosis

Background. A literature review of the use of video systems for magnification has suggested that so far, this novel magnification system has only been used to perform arterial anastomoses. The aim of this study was to evaluate the use of 2 low-cost methods of video-assisted magnification in microvascular venous anastomosis in rats. Methods. Thirty rats were randomly divided into 3 matched groups according to the magnification system used: the microscope group, with venous anastomosis performed under a microscope; the camcorder system group, with the procedures performed under a high-definition Handycam HDR-XR160; and the Photographic camera group, for which procedures were performed with an EOS Rebel T3i photographic camera. In both video system groups, a magnification system was connected to a 42-in. television by an HDMI cable. We analyzed weight, venous caliber, total surgery and anastomosis time, patency immediately and 14 days postoperatively, number of stitches, and histological analyses. Results. There were no significant differences between the groups in weight, venous caliber, or number of stitches. Anastomosis under the video systems took longer. Patency rates were similar between the groups, except for the photographic system group that has a lower patency rate at 14 days. The histological analyses were similar in all groups. Conclusion. It is possible to perform a venous anastomosis in rats through video system magnification, with a satisfactory success rate comparable with that for procedures performed under microscopes; however, the kind of video system has a great influence on the final patency.

Comparison of shaping ability of ProTaper Next and 2Shape nickel—titanium files in simulated severe curved canals

Aim: To evaluate the centering ability of ProTaper Next (PTN) and 2Shape (TS) nickel—titanium (NiTi) instruments in terms of maintaining the original root canal configuration in a simulated tooth with severe curvature. Methodology: Twenty standardized simulated curved root canals were prepared to an apical size of 0.25 mm using PTN and TS (n = 10 canal/group) nickel-titanium files. A gig was constructed to enable reproducible image acquisition using a photographic camera. Pre- and post-instrumented images were recorded and superimposed using a computer software. The ability of the instruments to remain centered in the canal was determined by calculating a centering ratio at three independent points of the simulated canal: coronal, middle and apical third of the curvature, using a computer software. Statistical analysis was performed using one-way analysis of variance (ANOVA) followed by independent sample t-test at 5% significance level. Results: No significant difference was found between the two systems (p > 0.05). At the apical third, the mean centering ratio was significantly higher than the centering ratio of the coronal and the middle thirds in both TS and PTN (p < 0.05). Conclusions: There were no significant differences in the centering ability of the ProTaper Next and 2Shape systems in simulated severe curved canals. Both systems exhibited some degree of transportation, especially in the apical third.

Determination of vegetation cover index under different soil management systems of cover plants by using an unmanned aerial vehicle with an onboard digital photographic camera

The permanent monitoring of vegetation cover is important to guarantee a sustainable management of agricultural activities, with a relevant role in the reduction of water erosion. This monitoring can be carried out through different indicators such as vegetation cover indices. In this study, the vegetation cover index was obtained using uncalibrated RGB images generated from a digital photographic camera on an unmanned aerial vehicle (UAV). In addition, a comparative study with 11 vegetation indices was carried out. The vegetation indices CIVE and EXG presented a better performance and the index WI presented the worst performance in the vegetation classification during the cycles of jack bean and millet, according to the overall accuracy and Kappa coefficient. Vegetation indices were effective tools in obtaining soil cover index when compared to the standard Stocking method, except for the index WI. Architecture and cycle of millet and jack bean influenced the behavior of the studied vegetation indices. Vegetation indices generated from RGB images obtained by UAV were more practical and efficient, allowing a more frequent monitoring and in a wider area during the crop cycle.

Las exposiciones de El Lissitzky a través del Cine-ojo

The Avant-Garde movements of the twentieth century explored the creative possibilities of new types of media in architecture, such as the photographic camera or cinema. In a series of experimental projects, authors such as El Lissitzky based their work on assimilating the human eye with a mechanical lens, making it possible to create new concepts of space. A simultaneous consideration of the resources of Vertov’s Cine-Eye in relation to the exhibition projects of El Lissitzky reveals some of his proposals as paradigmatic examples of the perceptive experimentation of the viewer in relation to art, and in a wider sense, to architecture. By analysing the cinematic resources of the film <em>Man with a Movie Camera</em> (1929), architectural aspects are analysed in the exhibition spaces of the Abstract Cabinet and PRESSA, identifying connections that break down the boundaries between the different disciplines.
