Avaliação de Algoritmos de Criptografia e Implementação de um Protocolo Leve para Comunicação entre Dispositivos IoT

Resumo—A criptografia tem papel fundamental na segurança em Internet das Coisas (IoT). No entanto, algoritmos e protocolos tradicionais de criptografia podem não ser adequados para IoT devido a heterogeneidade, baixa capacidade computacional e consumo energético dos seus dispositivos. O objetivo deste trabalho é avaliar diferentes algoritmos de criptografia e implementar um protocolo leve para comunicação entre dispositivos IoT. A avaliação dos algoritmos considera tempo de execução, uso de CPU, memória e consumo energético. O protocolo emprega os algoritmos SHA-3, AES e ECDH e é projetado a partir dos algoritmos avaliados. Resultados demonstram que o protocolo leva menos de 0,8 segundos para garantir confidencialidade e integridade na troca de mensagens usando uma placa Raspberry Pi como gateway e um ESP32 como dispositivo final.
Growth of Thin InAlP Native Oxides for GaAs Metal-Oxide-Semiconductor Devices

In an earlier reported study [1] on the scaling of In0.485Al0. 515P wet thermal native oxides towards thicknesses suitable for use in GaAs metal-oxide-semiconductor (MOS) devices, we observed that thin 7 nm oxide films showed Schottky-diode-like behavior with relatively large leakage current densities for capacitors of JL~4 x 10 A/cm at a field of 1 MV/cm. Attributing this to thin spots in the oxide, we here report a 400,000X reduction in the leakage (to JL~1 x 10 A/cm at 1 MV/cm) for similar MOS capacitors fabricated with improved processing from the same MOCVD-grown heterostructure. This leakage now compares favorably to the 9x10 A/cm value at 1 MV/cm achieved for an 8-nm-thick Al2O3 film grown by atomic layer deposition for a GaAs MOSFET device [2]. In this work, we present further data from transmission electron microscopy and variable-angle spectroscopic ellipsometry (VASE) measurements on the growth kinetics of device-quality InAlP native oxide films. In particular, a diffusion marker experiment has been used to establish for the first time the inward growth of InAlP native oxide, key to achieving an electrically clean oxide/semiconductor interface. Using e-beam lithography, 177 nm wide, 4 nm thick Cr lines spaced 2 μm apart were deposited on an InAlP surface. Following oxidation, the Cr marker was left on the outer surface, as verified by energy-dispersive x-ray spectroscopy (EDXS), confirming that oxidation must proceed primarily by inward diffusion of O to the oxide/InAlP interface where new oxide is produced (rather than by outward transport of the semiconductor elements In, Al and P to the outer oxide surface). This is unlike the reported oxidation of GaAs or AlGaAs, and allows preexisting surface impurities to remain on the outer oxide surface and thus not contaminate the interface causing interface states. This observation is consistent with demonstrations via capacitance-voltage characteristics that the Fermi level at InAlP oxide/GaAs interfaces is unpinned [3], making them suitable for MOS devices. We have recently reported GaAs channel MOSFET devices employing an ~11 nm InAlP native oxide as the gate dielectric with microwave frequency performance (ft=13.7 GHz, fmax=37.6 GHz) [4]. Using VASE thickness measurements presented here, the growth kinetics for wet oxidation of InAlP at temperatures of 420-500 °C are fit to the Deal-Grove linear-parabolic oxide growth law to yield diffusive and reactive growth mechanism activation energies of 1.52 and 1.16 eV/molecule, respectively. However, the oxide growth rate is predominantly reaction-rate limited (linear growth kinetics) for oxide thicknesses up to ~40 nm with an oxidation rate of 0.21-0.25 nm/min at 440 °C.
“There’s always an option” : Collaborative Writing of Multilingual Interactive Fanfiction in a Foreign Language Class

In the digital wilds, thriving storytelling practices (often in transcultural and multilingual contexts) share with Maker culture a belief in learning through doing, bricolage, collaboration, and playfulness. Key examples are fanfiction, a form of creative writing that transforms popular media in some way, and interactive fiction, a form of nonlinear narrative that verges on the world of gaming. This paper documents a pedagogical intervention carried out within the FanTALES project, which leverages creative writing and meaning-making practices from the digital wilds, in order to develop teaching and learning activities that engage secondary school learners in the writing of multilingual interactive fanfiction. Adolescent learners of English as a foreign language (N=21) wrote multilingual interactive fanfiction based on the digital game series Assassin’s Creed. Qualitative content analysis of focus groups with these learners suggests that they experienced intrinsic motivation and developed skills in language and storytelling as well as transversal competences. They also dealt with a lowered sense of autonomy due to the open-endedness of the tasks, and struggled with a lack of sufficient knowledge about storytelling practices and the source text, as well as with project management. Potential improvements for the pedagogical implementation include more scaffolding of the tasks, and better integration with curriculum and assessment.
Removal Characteristics of Endocrine Disrupting Compounds (EDCs), Pharmaceutically Active Compounds (PhACs) and Personal Care Products(PCPs) by NF Membrane

Reports of endocrine disrupting compounds (EDCs), pharmaceutically active compounds (PhACs), and personal care products (PCPs) have raised substantial concern in important potable drinking water quality issues. Our study investigates the removal of EDCs, PhACs, and PCPs of 10 compounds having different physico-chemical properties (e.g., molecular weight, and octanol-water partition coefficient (Kow)) by nanofiltration (NF) membranes. The rejection of micropollutants by NF membranes ranged from 93.9% to 99.9% depending on solute characteristics. A batch adsorption experiments indicated that adsorption is an important mechanism for transport/removal of relatively hydrophobic compounds, and is related to the octanol-water partition coefficient values. The transport phenomenon associated with adsorption may also depend on solution water chemistry such as pH and ionic strength influencing the pKa value of compounds. In addition, it was visually seen that the retention was somewhat higher for the larger compounds based on their molecular weight. These results suggest that the NF membrane retains many organic compounds due to both hydrophobic adsorption and size exclusion mechanisms.
Robust Tracking Control of a Quadrotor Unmanned Aerial Vehicle-Suspended Payload System

In this article, the control problem for the underactuated dynamic system, which consists of a quadrotor unmanned aerial vehicle and a suspended payload is investigated under the effects of unknown exogenous disturbances. A novel nonlinear controller based on the robust integral of the sign of the error is developed to deal with the position trajectory tracking control and the antiswing control of the suspended payload with the presence of unknown air turbulence. The Lyapunov-based stability analysis is employed to prove the asymptotic stability of the closed-loop system. The real-time experimental results are presented to verify the performance of the proposed control design.
Impact of Meteorological Conditions on the Ecological-Economic Systems of Russia

Global environmental problems affect all spheres of life, incl. the economic development. As a result, it becomes necessary to study the influence of the environment on economic development, as well as reverse interaction in the form of ecological and economic systems. The climatic factor is of great importance for the state of ecological and economic systems, therefore, when conducting an analysis at the regional level, it is necessary to differentiate the constituent entities of the Russian Federation pursuant to the climatic conditions of agricultural production. The article substantiates changes in the relationship between meteorological conditions and agricultural production, which proves the need to distinguish groups of regions by the climatic factor to assess the level of ecological and economic development. All this will lead to an increase in the effectiveness of measures aimed at environmental and economic development, will help to more efficiently use natural resources and reduce the burden on the environment.
The role of HR in organizations In Uzbekistan

Human resource management Is one of the most important aspects in any organisation. In hospitality industry, if we talk about hotels within the same categories of stars, nowadays, they would be adhering to more or less similar standards i.e. room and bed size, interior design, bathroom, lighting and breakfast and have almost similar facilities which they offer.
Compost in pellet form and compost moisture content affect phosphorus fractions of soil and compost

ABSTRACT Phosphorus (P) bioavailability depends on the forms of inorganic and organic P (Pi and Po). Our objectives were to investigate the effects of compost forms (pellet or non-pellet) on soil P forms, and to characterize the mineralization of Po and the changes in P forms in compost of different moisture contents. Laboratory incubation experiments were conducted; (1) pelletized and ground pelletized poultry manure composts were applied to an Andosol and incubated for 56 d, and (2) poultry manure composts were prepared with five levels of moisture content (0.2, 0.4, 0.6, 1 and 2 kg kg−1-dry matter). Phosphorus forms in the soil and compost were determined by sequential fractionation. Compost amendment increased Truog P and labile Pi in the soil. A greater increase in Truog P and labile Pi (anion-exchange membrane (AEM)-Pi + NaHCO3-Pi) was observed in the soil amended with pelletized compost compared with the soil amended with ground compost. Phosphorus mineralization of poultry manure compost was enhanced at higher moisture contents. Moisture contents of pelletized compost were above 1 kg kg−1 under standard soil moisture conditions. Above compost moisture contents of 1 kg kg−1, labile Pi levels reached a maximum at 26 d and subsequently remained stable. The increase in labile Pi was mainly attributable to a decrease in HCl-Po. These results indicate that compost in pellet form and compost moisture content strongly affect bioavailability of compost P.
Cellmates versus family – the sense of belonging among tattooed prisoners

Introduction: The sense of belonging in a group can be a form of adaptation to the conditions of prison isolation. However, excessive group identification could result in negative consequences for the identity of an individual. The sense of support in social relations is a significant personal resource of convicts. The social identity of convicted persons influences their behaviour, and thus the effect of penitentiary interactions. Hence, the aim of the study was to assess the sense of belonging in a group among convicts with body modifications. Methods: The research was conducted in penitentiary units at the District Inspectorate of the Prison Service in Gdańsk (Poland). Fifty-eight re-sentenced convicts participated in the study (36.2% did not have body modifications, and 63.8% had tattoo/tattoos). The age of the respondents ranged from 18 to 62 years (M = 35.12; standard deviation, SD = 10.98). The participants completed the Group Identification Scale (Mael and Ashforth, 1992), the Identity Fusion Scale (Gómez et al., 2011) and the measure of identity fusion (Swann et al., 2009). Results: The study showed that convicts declare a very weak sense of belonging with their cellmates (55.2%) and a very strong sense of belonging with their family (44.8%). A relationship was observed between younger age and identity fusion; however, it was on the border of a significant statistical trend. Conclusions: Interpersonal relationships used as a personal resource in the social rehabilitation process can be extremely important for the probability of recidivism in the future. Especially, non-standard methods may allow convicts to test themselves in a new role. The self-concept should not be formatted through the prism of social stereotypes of prisoners, but with the simultaneous support of the family, which may strengthen socially acceptable behaviours.
Probiotics, Prebiotics, Synbiotics and its Health Benefits

Probiotics are defined as ̳live microorganisms which when administered in adequate amount confer health benefits to the host‘ (FAO/WHO, 2002). Alternatively, probiotics have been defined as live microbial feed supplements that beneficially affect the host animal by improving its intestinal microbial balance (Fuller, 1989). Probiotics were originally used to improve the health of both animals and humans through the modulation of the intestinal microbiota. At present, several well-characterized strains of Lactobacilli and Bifidobacteria are available for human use to reduce the risk of gastrointestinal (GI) infections or treat such infections (Salminen et al., 2005). Some of the beneficial effects of probiotic consumption include improvement of intestinal health by the regulation of microbiota, and stimulation and development of the immune system, synthesizing and enhancing the bioavailability of nutrients, reducing symptoms of lactose intolerance, and reducing the risk of certain other diseases (Fig. 1–3) (Kumar et al., 2009a, Kumar et al., 2009b, Kumar et al., 2010, Kumar et al., 2011a, Kumar et al., 2011b; Nagpal et al., 2007, Nagpal et al., 2010, Nagpal et al., 2011; Yadav et al., 2007a, Yadav et al., 2007b, Yadav et al., 2008).

What Is the Impact of Mutual Funds' ESG Preferences on Portfolio Firms?

Mutual funds must publish policies announcing how they generally vote on the different ballot items at the shareholder meetings of their portfolio firms. I manually collect 17,000 of these policies for a sample of 29 of the largest U.S. mutual fund families over 2006-2018. I find that voting policies are a major predictor of funds' voting behavior. Exploiting staggered changes in funds' voting policies, I show that investee companies adopt their mutual fund shareholders' preferred governance provisions. This adoption is the result of mutual fund shareholders' active voting. Announced voting policies also stimulate strategic proposal submissions by non-mutual fund shareholders.
Clinico-Radiographic spectrum of cleidocranial dysplasia: A case series

The coronoid process appeared slender, gonial angles on both sides of the mandible were obtuse, and maxillary sinuses were underdeveloped. Bell-shaped thorax and hypoplastic clavicles were seen on the chest radiograph. Lateral and PA view of the skull revealed open fontanelles, depressed, bulb-shaped skull, and multiple wormian bones. Family history did not reveal similar findings. Thus, a detailed clinical and radiological examination revealed her to be a case of CCD 1). A multidisciplinary treatment approach was advised, which included extractions of mobile teeth, periodontal therapy, and prosthetic rehabilitation. ABSTRACT Cleidocranial dysplasia (CCD) is a rare autosomal dominant disorder that presents with skeletal dysplasia and dental manifestations. The most common features seen in CCD are aplastic or hypoplastic clavicles, late closure of fontanelles, open skull sutures, and dental abnormalities which include mainly delayed exfoliation of primary teeth and delayed eruption of permanent teeth, with multiple impacted supernumeraries. A relatively low number of multiple case studies are reported in the literature, with only eight reporting on more than three affected individuals. Here, we report a case series of five such rare cases showing characteristic clinical and radiographic features of CCD.

Component Analysis in Saffron (Crocus sativus L.) for Floral and Vegetative Attributes

Saffron (Crocus sativus L.) belongs to family Iridaceae, plants of this family are herbs with rhizomes, corms or bulbs. Saffron is a perennial herbaceous plant attaining a height of 25 to 40 cm having sub hysteranthous behaviour. Foliar structure and floral organs constitute main parts of saffron plants (Nehvi and Salwee, 2010). Biological cycle is completed in 5 to 6 stages. It has two year plant cycle which starts from the month of July of the first year and the apical buds take a year to acquire its maximum size, and becomes a fully grown corm, while it takes another year before it is depleted and ends up with a wrinkled black disc. Usually the degradation of mother corm is visible at the beginning of November which looks quite wrinkled and flat (Medina, 2003). The species in the genus Crocus have underground fleshy corms, dark green leaves with whitish median strip. Their leaves appear with or after flowers. A plant may have one or several flowers.

ACE Genotype Distributions Differ between Sporadic and Familial Hypertrophic Cardiomyopathy

This study investigated the frequency of ACE genotypes in sporadic hypertrophic cardiomyopathy (HCM) and compared these frequencies to those found in the general population and in familial HCM. Delineation of the genotype of a 287 bp fragment in the ACE gene of 10 patients with confirmed sporadic HCM demonstrated that 2 (20%) were of the DD genotype, 5 (50%) of the ID genotype, and 3 (30%) of the II genotype. These genotype distributions did not differ significantly from controls (p < 0.57). Comparison of the present results with genotype frequencies in familial HCM reported in prior studies revealed a significant difference in genotype distribution between sporadic and familial HCM (p < 0.04). These findings indicate that the frequency of the ACE genotype does not appear to differ between patients with sporadic HCM and the general population. However, the results suggest that, with regard to the ACE polymorphism studied, genetic differences may exist between the sporadic and familial forms of HCM.
Design of Yaw and Tilt Alignment Inspection System for a Low-Resolution 3D LiDAR Using Planar Target

It is crucial to attach a LiDAR (Light Detection and Ranging), a 3D sensor for a mobile platform such as robot and vehicle within the acceptable misalignment to detect the relative positions of surrounding obstacles accurately. This paper proposes a novel inspection method to estimate the yaw and tilt alignment of a LiDAR after the sensor attachment. The proposed method uses a planar target board to estimate the yaw and tilt angles of a low-resolution LiDAR with milli-degree precision. Experiments were conducted to evaluate the accuracy and precision of the proposed method with the designed test-bench that can control the reference pointing angle of the LiDAR from −10 to 10 degrees. The experiment results on Velodyne VLP-16, a low-resolution LiDAR with 16 channels, showed that the proposed system estimated the yaw and tilt angles within accuracy and precision of 0.1 degrees.
THE LIMIT TOWARD EMPTINESS: URBAN VOIDS AS PUBLIC SPACE

关键词 空白;公共空间;城市虚空;空地;模糊地块 ABSTRACT Cities are spatial aggregations of capital and culture that host and serve a vast array of different and often contradictory publics. For this reason, cities need spaces that accept and encourage multiple types of representations and forms of expression: planned and spontaneous, regulated and unregulated, permanent and temporary. This essay argues that emptiness is a spatial quality that can satisfy these needs and that urban voids are a paradigmatic example of empty spaces. The term “void” implies that these spaces are emptied of the value typically associated with cities as places of capital accumulation. But this emptiness (of capital, real estate value, efficacy, or production) is what enables other sensibilities and opportunities to emerge. In other words, a lack of value is what makes these vacant spaces appear as marginal, and this marginality is precisely what gives the urban voids the possibilities for publicness that other urban spaces do not have. Despite the social opportunities offered by urban voids, the evanescence of emptiness ultimately exposes the limits of urban voids.
Social Network Analysis on Tourist Perception of Museum Tourism

Based on the comments of museum tourists, social network-based tourist perception analysis is conducted for tourists in different types of museums. This paper collects the evaluative text information of museum tourists on dianping.com, and analyzes these comments of museum tourists by using high frequency words and structural homomorphism to find out the key factors that affect the development of museum tourism. The research shows that tourists have formed certain brand awareness about museums in Shaanxi Province as a whole, showing the cognition and definition around the profound historical and cultural deposits. Combined with the structural homomorphism of high frequency words used by museum tourists, this paper makes a comparative analysis of different types of museums, and finally gives the support for making decisions on the development of museums around the three dimensions of the exhibition contents, the tourist experience and tour modes.
One Day International (ODI) Cricket Match Prediction in Logistic Analysis: India VS. Pakistan

Cricket is now a game of enchantment, refreshing and physical strength of 22 players. As the popularity of one-day international (ODI) games increases, it is essential to understand the game results' potential predictors. The advantage at home ground, coin-toss result, decision on first batting or fielding first, and day-to-day games are such popular cricket literature variables. The Indian subcontinent is like a game of thrill, war, friendship, and finally, and the best fighting teams are India and Pakistan. This study emphases a comprehensive analysis of the importance of these important predictors by various statistical calculations. For all ODI matches played by India & Pakistan from 1978 to 2019, information was manually collected from the website, www.espncricinfo. com. For purposes of model-building, logistic regression is applied retrospectively to data already obtained from previously played matches. Univariate, bivariate, binary and skewed logistic regression on the multivariate context are considered. In bivariate analysis, only the day/day-night format match is statistically significant at a 5% level of significance in favor of winning the Indian team. In binary logistic regression, the odds of winning team India was 70.6% times more for home ground and 2.28 times more for data compared to day-night times match. For skewed logistic, the odds of conquering for both teams increase, but the model performs comparatively worse than binary logistic regression.
