Control of quadrotor by designing Third-order Supertwisting SMC

Abstract— This paper studies the modeling and control of quadcopter. It models the quadcopter nonlinear dynamics using Lagrange formalism and design controller for attitude (pitch & roll), heading & altitude regulation of quadrotor. Mathematical modeling includes aerodynamic effects and gyroscopic moments. One Non-linear Control strategy, Third-Order SMC based on a super-twisting algorithm has been proposed. Third-Order SMC Controller is designed for regulation control problem with the four control variables. The Controller has been implemented on the quadrotor physical model using Matlab/Simulink software. Finally, the performance of the proposed controller was demonstrated in the simulation study. The simulation results show excellent modeling and control performance.
Photoinduced reversible gel–sol transitions of dicholesterol-linked azobenzene derivatives through breaking and reforming of van der Waals interactions

A series of new symmetric dicholesterol-linked azobenzene gelators with different spacer lengths have been synthesized. The compounds with spacers of zero, two or six methylene units are denoted as DCAZO0, DCAZO2 and DCAZO6, respectively. A gelation test reveals that a subtle change in the length of the spacer can produce a dramatic change in the gelation behavior of the compounds. DCAZO2 obtains the minimum gelation concentration among the three gelators. For cyclopentanone gel of DCAZO2, the reversible gel–sol transitions by irradiation with UV and visible light are investigated by UV-vis absorption and circular dichroism (CD) spectra, SEM, TEM and XRD analyses. Upon UV irradiation of the gel, trans–cisphotoisomerization of the azobenzene groups occurs, the change in molecular polarity leads to the breaking of van der Waals interactions, resulting in the gel–sol transition. The gel can be recovered by the reverse cis–transphotoisomerization after the exposure to visible light. SEM, TEM and XRD studies reveal that the gelator molecules self-assemble into one-dimensional fibers with diameters 50–100 nm in an anticlockwise direction, which further crossed-linked to form three-dimensional networks.
Isolation, identification and detection of some acriflavine (Acr) Efflux pumps genes in uropathogenic E. coli isolates isolated from Iraqis patients

Urinary Tract Infections (UTIs) are one of the most prevalent bacterial infections. During this study, which was extended from November 2018 to April 2019, 30 samples were collected from patients with confirmed UTIs at Al-Husseini Teaching Hospital, Karbala, Iraq. The results show that 24 samples of them were caused by E. coli, while the rest were caused by Staphylococcus aureus, Enterobacter aerogenes, Acinetobacter spp and Serratia liquefaciens. Antibiotic sensitivity test for the isolated E.coli strains using Vitek 2 compact system showed that all the isolates were sensitive to imipenem and meropenem, Carbapenems antibiotics. However, PCR results interestingly showed that all the isolates have AcrA and AcrB genes, important genes in the acriflavine (Acr) Efflux System. In other words, these bacterial isolates have the capability to shift to resistance ones when suitable conditions become available. The ramifications of results are vast and can help to explain the increasing frequency of carbapenems-resistance strains.
Synthesis and characterization of graphene films by hot filament chemical vapor deposition

In this study, we tried to deposit graphene films on copper substrates using hot filament chemical vapor deposition. The quality and the electronic and structural properties of deposited carbon films were investigated by Raman spectroscopy. Three samples of carbon films on copper substrates were produced and designated as A, B and C according to the preparation conditions. Experiments were conducted at temperatures of 800 and 1000 °C, a gas pressure of 500 torr and exposure times of 1, 5 and 30 min. The intensity of the disorder-induced D peak is observed relative to that of the G peak. The shape of the 2D peak gives us information about the number of layers. The lineshape of the 2D peak of sample C indicates few-layer graphene, whereas Raman spectra of samples A and B indicate hydrogenated few-layer graphene.
An iterative-recursive SOS-based method for separation of Post-Nonlinear Mixtures

—Independent Component Analysis (ICA) methods are widely used in the linear Blind Source Separation (BSS) problem. Nevertheless, for some practical cases, the linear assumption is not valid, requiring nonlinear mixing models. The Post-Nonlinear is one of the few nonlinear models in which ICA is able to perform source separation. In previous works, an iterative SOS-based algorithm was proposed, combining elements of AMUSE and SOBI. However, instantaneous estimations of the correlation matrix could lead to a loss of performance. In that sense, in this work, we modify the previous algorithm to use an iterative-recursive estimation of the correlation matrices. Due to the SOS-based approach, sources should present a temporal dependency and certain constraints are required on the separation structure. Results show a good performance of the proposed algorithm.
The Determination of Scopoletin in Environmental Tobacco Smoke by High-Performance Liquid Chromatography

Abstract A high-performance liquid chromatographic (HPLC) method was developed for the quantification of scopoletin in environmental tobacco smoke (ETS) for use as an indicator of tobacco smoke in indoor air. Samples were collected on 1 μm pore size Fluoropore membrane filters and extracted with methanol (MeOH). This single extract was used for four analyses including scopoletin after dilution with 1% aqueous acetic acid (HAc). Scopoletin was determined on an octadecyl silane, silica-based column with fluorescence detection. A mobile phase gradient of 1% HAc and 99% acetonitrile + 1% glacial acetic acid was used. The method was reproducible with a relative standard deviation of 6.4%. Percent recovery was 98%. Analyses of smoke from oak leaves indicated the presence of scopoletin, but it was not detected in fireplace smoke. A short sampling time of one h was required and the procedure was capable of detecting < 3 ng m−3.
Desh: Deep Learning for HPC System Health Resilience Extended

HPC systems are well known to endure service downtime due to increasing failures. With enhancements in Supercomputing architectures and design, enabling resilience is extremely challenging due to component scaling and absence of well defined failure indicators. Supercomputing system logs are notorious to be complex and unstructured. Efficient fault prediction to enable proactive recovery mechanisms is the need of the hour to make such systems more robust and reliable. This work addresses such faults in computing systems using a recurrent neural network based technique called LSTM (long short-term memory). We present our framework Desh 1 : De ep Learning for HPC S ystem H ealth, which entails a procedure to diagnose and predict failures with acceptable lead times. Desh indicates prospects of indicating failure indicators with enhanced training and classification for generic applicability to other systems. This deep learning based framework gives interesting insights for further work on HPC system reliability.
Modelling corporate bond rating with the use of market–based indicators

The paper presents an estimation of corporate bond rating models based on both financial and market company indicators. The analysis will be carried out for companies in the oil and gas industry having a rating assessment from Moody's rating agency. The paper aims to offer a more detailed understanding of the relationship between company market indicators and bond rating classification. Bond rating models will be estimated by multivariate statistical methods such as discriminant analysis and logistic regression. The contribution of the paper is to identify variables with a significant impact on corporate bond rating in the selected industry. The models being derived allow classifying bond rating of companies with relatively high accuracy, even when a limited set of input variables is considered. The practical use of models lies in the area of management decision process and managing credit risk.

What voiced obstruents symbolically represent in Japanese: evidence from the Pokémon universe

Abstract Kawahara, Noto, and Kumagai (2018b) found that within the corpus of existing Pokémon names, the number of voiced obstruents in the characters’ names correlates positively with their weight, height, evolution levels and attack values. While later experimental studies to some extent confirmed the productivity of these sound symbolic relationships (e.g. Kawahara and Kumagai 2019a), they are limited, due to the fact that the visual images presented to the participants primarily differed with regard to evolution levels. The current experiments thus for the first time directly explored how each of these semantic dimensions—weight, height, evolution levels, and attack values—correlates with the number of voiced obstruents in nonce names. The results of two judgment experiments show that all of these parameters indeed correlate positively with the number of voiced obstruents in the names. Overall, the results show that a particular class of sounds—in our case, a set of voiced obstruents—can signal different semantic meanings within a single language, supporting the pluripotentiality of sound symbolism (Winter, Pérez-Sobrino, and Brown 2019). We also address another general issue that has been under-explored in the literature on sound symbolism; namely, its cumulative nature. In both of the experiments, we observe that two voiced obstruents evoke stronger images than one voiced obstruent, instantiating what is known as the counting cumulativity effect (Jäger and Rosenbach 2006).
DETERMINATION OF TRANSPORT PARAMETERS IN POLYMERIC SYSTEMS FOR INDUSTRIAL WASTEWATER TREATMENTS

In this paper the influence of dispersed macromolecules in the process of selective mass transfer through aqueous systems was studied in order to apply this knowledge in the design of reactors for industrial wastewater treatments. The application of biomass, usually composed of biopolymers production accessible, is currently in great development. Particularly, their use in case of retention of heavy metals in liquids. The discovery of these retention phenomena provides the foundation of new technologies for remediation and the recovery of these metals. To evaluate the retention capacity or the mobility of charged species in TAD (stirred tank batch) and TUB (tubular) reactors, we studied the behavior of metal ions in media of different ionic strength with scleroglucan (polar polymer), xanthan (anionic polyelectrolyte) and polyoxyethylene (virtually non-polar). The study using anions and cations of varying mass and charge in the aforementioned systems, was done by Synchrotron Radiation micro X-Ray Fluorescence (SRμXRF). A double cell that allow determining concentrations at different times and positions was designed.

POLISH JOURNAL OF NATURAL SCIENCES

A 3 x 3 factorial experiment was carried out to investigate the carcass yield and meat quality characteristics of growing pigs subjected to qualitative and quantitative feeding strategies. Eighty one (81) Large White growing pigs (54 males and 27 females) with initial weight of 6.7 ± 0.39 kg were assigned to nine treatments of three replicates of three pigs per replicate. Treatments consist of three levels of qualitative (20, 18 and 16% crude protein) and quantitative (ad libitum, 90% and 80% ad libitum) feed restriction. Fasted weight values (31.75, 26.77, 23.98 kg) of growing pigs significantly (p < 0.05) decreased with decreasing levels of dietary crude protein. The same trends were observed in other carcass yield parameters of growing pigs studied except left carcass weight which was not significantly affected by qualitative restriction. Dietary crude protein levels had significant (p < 0.05) effect on percentage cooking loss with the values obtained increasing with decreasing levels of dietary crude protein content. Quantitative feed restriction influenced (p < 0.05) head, shoulder, fore-leg, hind-leg, liver, kidney, spleen and stomach weights but had no influence on meat quality parameters of growing pigs. Interaction between qualitative and quantitative restriction had significant effect on all carcass yield parameters but with no effect on meat quality indices considered in this study. It can be concluded from this study that qualitative and quantitative restriction can be used as management tool to alter the carcass yield, cut-parts and visceral organs of growing pigs; the cooking loss of pork likewise was impacted positively by the quality of ration offered.

The Converter/Distributor (C/D) model (Fujimura 2000) provides a comprehensive and explicit framework to model how the phonological, prosodic organization is mapped onto actual speech production. The goal of this paper is (i) to walk readers through how to construct the prosodic representations of the C/D model from actual articulation data, and (ii) discuss some crucial concepts of the C/D model. Some basic hypotheses of the C/D model are (1) phonological syllable magnitude increases with increased sentence stress, (2) amount of jaw displacement is the articulatory correlate of syllable magnitude, (3) phonological syllable timing is calculated from speed patterns of the crucial articulators of onset and coda consonants, and (4) once syllable magnitude and syllable timing are determined, we can automatically calculate phonological phrasing patterns, with phrase boundaries which come with predicted durational values. All of these computational aspects of the C/D model can and should be tested empirically. In this paper, we attempt to explain and discuss these aspects of the C/D model in detail, especially for those readers who are not already familiar with the model.
EFFECT OF LOW COMBUSTION TEMPERATURE AND ALKALINE TREATMENT ON BIOCHAR PROPERTIES FROM RICE HUSK

Biochar is a form of carbon that is produced by heat decomposition of biomass. Pyrolysis under the inert atmosphere is a well-established method to produce biochar with high carbon yield. However, the technology is yet to be fully developed to become viable for commercial applications due to the need of utilisation of inert conditions. In this study, combustion technique was adapted as the novel method to produce biochar from rice husk with low cost. Rice husk is an excellent source for production of biochar due to its high lignin and carbon content. Alkaline treatment of rice husk was carried out with the aim to improve its pore characteristics and physicochemical properties. Hence, rice husk has been subjected to a combination of various treatments, including combustion at different temperatures (200, 300 and 400 oC) and NaOH treatment. Several analytical techniques such proximate analysis, ultimate elemental analysis (CHNS), X-ray diffraction (XRD) and BrunauerEmmett-Teller (BET) were employed to analyse the characteristics of different biochar samples. Highest carbon content obtained was about 44.25% with NaOH treatment followed by combustion at 200 °C. All the tested samples exhibited amorphous structure. It has been found that specific surface area values between 305 and 467 m g were obtained when alkaline treatment of the rice husk showing the viability of combustion method for biochar production.
Kinetic and thermodynamic analysis of proteinlike heteropolymers: Monte Carlo histogram technique

Using Monte Carlo dynamics and the Monte Carlo histogram method, the simple three‐dimensional 27 monomer lattice copolymer is examined in depth. The thermodynamic properties of various sequences are examined contrasting the behavior of good and poor folding sequences. The good (fast folding) sequences have sharp well‐defined thermodynamic transitions while the slow folding sequences have broad ones. We find two independent transitions: a collapse transition to compact states and a folding transition from compact states to the native state. The collapse transition is second‐order‐like, while folding is first‐order‐like. The system is also studied as a function of the energy parameters. In particular, as the average energetic drive toward compactness is reduced, the two transitions approach each other. At zero average drive, collapse and folding occur almost simultaneously; i.e., the chain collapses directly into the native state. At a specific value of this energy drive the folding temperature falls below .
Purified oleosins at air–water interfaces

Oleosins are low molecular mass proteins that are distinguished from other proteins for their extended central hydrophobic domain which covers almost half of its entity. For this work, they were extracted from isolated maize germ oil bodies. The purification steps included washing with diethylether and a chloroform–methanol–water mixture. Their amphipathic terminal domains positioned at the organelle surface, where they strongly interact with the surface polar phospholipids, made the application of a third washing step with acetone essential. Although oleosins are well known for their insolubility in water, we were able to prepare aqueous buffer solutions of 0.008 wt% at pH 8.0. The interfacial behaviour of oleosins was studied, in order to predict their ability to stabilize foams. Even at low concentrations they were capable of decreasing the interfacial tension of air–water interfaces to values similar to those obtained from milk protein or egg yolk apolipoproteins adsorption. Pendant drop profile analysis showed that the dilatational elastic modulus was frequency-dependent, but at the same time the elastic to viscous modulus ratio was frequency-independent and below 0.1. The results indicate that oleosins might have a high potential as foam stabilizers, a fast developing and challenging field.
HISTEX (HISTORY EXERCISER): AN OVERVIEW

: We present HISTEX, a tool for testing the implementation of isolation levels of relational database management systems. It is a multi-process application and executes input histories in a generic transactional notation on commercial DBMS platforms. HISTEX could be used to discover potential errors in the implementation of Isolation Levels by Relational Database Management Systems or cases where a system behaves over restrictively. It can also be used for performance measurements related to database workloads executing on real database systems instead of simulated environments. HISTEX has been implemented in C by utilizing Embedded SQL. However, many of its ideas could be reincarnated in new implementations that could rely on other database connectivity paradigms such as JDBC, JPA etc. We expect that by presenting some of the ideas behind its development we could re-invigorate some fresh interest and involvement in the research community regarding such tools.
