Educational Robotics and Tangible Devices for Promoting Computational Thinking

Recently, efforts have been made to add programming activities to the curriculum that promote computational thinking and foster 21st-century digital skills. One of the programming modalities is the use of Tangible Programming Languages (TPL), used in activities with 4+ year old children. In this review, we analyze solutions proposed for TPL in different contexts crossing them with non-TPL solutions, like Graphical Programming Languages (GPL). We start to characterize features of language interaction, their use, and what learning activities are associated with them. Then, in a diagram, we show a relation between the complexity of the languages with factors such as target age and output device types. We provide an analysis considering the type of input (e.g., TPL versus GPL) and output devices (e.g., physical robot versus graphical simulation) and evaluate their contribution to further insights about the general trends with respect to educational robotic systems. Finally, we discuss the opportunities to extend and improve TPLs based on the different solutions identified.

Malicious Attack Identification Using Deep Non Linear Bag-of-Words (FAI-DLB)

Online media have flourished in modern years to connect with the world. Most of those stuff users share on blogs like facebook, twitter and many other are pessimistic or just middle spirited. Further, an increasingly professional anti - spyware technologies are dependent on Machine Learning(ML) technology to secure malicious consumers. Over the past few years, revolutionary learning approaches have yielded remarkable outcomes and have immediately generated photos, characters and text interpretations of dynamic weak points. The Purple consumer frequency makes the troll and attacker aim an enticing one. The users will learn the controversial topics and techniques used by malware from articles with ties to harmful material and bogus applications. It is essential to build and customize a lot of potential functionality in vulnerability and application developers around the world. To represent a public web firmware assault with deep logistic inference using Extreme Spontaneous Tree (FAI-DLB). A corresponding output device is named harmful or benign by training an FAI-DLB with different modulation clustered with such a normal or anomalous API. It was therefore equipped to locate a suspicious sequence in unidentified firmware of FAI Deep LB. The outcome demonstrates a good actual meaning of 96.25% and a low spyware assault of 0.03%.

Mathematical Principles of Object 3D Reconstruction by Shape-from-Focus Methods

Shape-from-Focus (SFF) methods have been developed for about twenty years. They able to obtain the shape of 3D objects from a series of partially focused images. The plane to which the microscope or camera is focused intersects the 3D object in a contour line. Due to wave properties of light and due to finite resolution of the output device, the image can be considered as sharp not only on this contour line, but also in a certain interval of height—the zone of sharpness. SSFs are able to identify these focused parts to compose a fully focused 2D image and to reconstruct a 3D profile of the surface to be observed.

ANALYSIS AND MODELING OF THE KINETICS OF THE EXTRACTION OF VEGETABLE OILS ON THE TURNS OF OIL-PRESSING UNITS

Используемые в промышленности форпрессы для предварительного съема масла и экспеллеры для окончательного отжима различаются геометрией витков шнекового вала. В настоящее время наметилась тенденция к объединению этих аппаратов в единый маслоотжимной агрегат на основе геометрии наборов витков форпресса и экспеллера или двух совращающихся шнековых валов, позволяющих значительно увеличить продолжительность процесса за счет увеличения длины шнековых каналов. Предложено аналитическое решение математической модели распределения потока и гидростатического давления масличного материала в процессе отжима растительного масла непрерывным способом в канале витка шнекового пресса. Показана возможность математического моделирования этого процесса на основе двумерной модели слоистого течения неньютоновской жидкости с учетом геометрии витков шнекового вала и скорости его вращения, позволяющая рассмотреть этот процесс для современных маслоотжимных агрегатов на основе геометрии наборов витков форпресса и экспеллера или двух совращающихся шнековых валов. Получена оценка пропускной способности канала с учетом сопротивлений выходного устройства, а также аналитическое решение распределения потока и гидростатического давления масличного материала в процессе отжима растительного масла. Used in the industry the pre-oil extraction pre-presses and the expellers for the final spin differ in the geometry of the screw shaft turns. Currently, there is a tendency to combine these devices into a single oil-pumping unit based on the geometry of the sets of turns of the forpress and expeller or two rotating screw shafts, which can significantly increase the duration of the process by increasing the length of the screw channels. An analytical solution is proposed for a mathematical model of the distribution of flow and hydrostatic pressure of oil-bearing material in the process of pressing vegetable oil in a continuous way in the channel of the screw press. The possibility of mathematical modeling of this on the basis of a two-dimensional model of a layered flow of a non-newtonian fluid, taking into account the geometry of the turns of the screw shaft and the speed of its rotation, is shown, which makes it possible to consider this process from a single point of view of using modern oil-extracting units, both on the basis of the geometry of sets of turns of the forpress and expeller, and two screw shafts. As a result of the conducted studies, an estimate of the channel capacity was obtained, taking into account the resistances of the output device, as well as an analytical solution for the distribution of the flow of oilseed material and the hydrostatic pressure of the oilseed material during the extraction of vegetable oil.

EEG Controlled Exoskeleton

A physically paralyzed person is doomed to stay on a chair or the bed making him completely at mercy of a helper. To help these patients this device uses a Brain Computer Interface (BCI). A brain-computer interface (BCI) is a computer-based system that acquires brain signals, analyses them, and translates them into commands that are relayed to an output device to carry out a desired action. In principle, any type of brain signal could be used to control a BCI system. This device is an Exoskeleton made of steel/iron that will be attached the Patient who is Physically Paralyzed. An exoskeleton is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example, a human. It will give support to the Patient while standing up so that he/she doesn’t fall down. The Brainwaves being read by the EEG will be fed to a neural networking model coded using Google’s Tensor Flow which will create a model with a high enough accuracy to understand the intentions of the patient i.e. whether to stand up or not and the direction of movement. The Real-time data will be given to the existing model and the motors of the exoskeleton will move accordingly.

Aiming for G7 Master Compliance through a Color Managed Digital Printing Workflow (CMDPW): Comparison of Compliance with Output Device Profile (ODP) vs. Device Link Profile (DLP)

The purpose of this applied research was to determine the influence of device link profile (DLP) in the color reproduction aimed at the G7 master compliance. The quality of digital color printing is determined by these influential factors: screening method applied, type of printing process, ink (dry-toner or liquid-toner), printer resolution and the substrate (paper). For this research, only the color printing attributes such as the G7 colors hue and chroma, gray balance, and overall color deviations were analyzed to examine the significant differences that exist between the two output profiles [Output Device Profile (ODP) vs Device Link Profile (DLP)]. These are the color attributes which are monitored and managed for quality accuracy during the printing. Printed colorimetry of each profile from the experiment was compared against G7 ColorSpace GRACoL 2013 (CGATS21-2-CRPC6) in CIE L* a* b* space using an IDEAlliance (Chromix/Hutch Color) Curve 4.2.4 application interface with an X-Rite spectrophotometer with an i1iO table. The measured data of each profile were run through this application (Curve 4.2.4). The data were analyzed by using the Verify Tool of the Curve 4.2.4 application to determine the pass/fail of G7 master compliance levels using G7 ColorSpace tolerances (G7 Grayscale, G7 Targeted, and G7 Colorspace). Analyzed data from the experiment revealed that the printed colorimetric values of each profile (G7 Grayscale, G7 Targeted, and G7 Colorspace) are in match (aligned) with the G7 master compliance levels (reference/target) colorimetric values (G7 Grayscale, G7 Targeted, and G7 Colorspace). Therefore, the press run was passed by the Curve 4 application for both the profiles used/tested towards aiming for G7 master compliance.

Parameters of the seed output device of the ergot isolation machine

Grains of rye, wheat, barley and oats are often infected with poisonous ergot fungi. Therefore, it is necessary to clean the grain from harmful impurities. Modern machines do not provide the isolation of ergot sclerotia from grain due to the closeness of their properties in terms of air flow rate and linear dimensions. Cleaning seeds from ergot sclerotia, which have a density lower than the density of the grain, is possible in an aqueous solution of salt. When developing such a machine, research is required to study the residence time of grain in an aqueous salt solution. Grains are considered in the form of a transverse cylinder and an elongated ellipsoid of rotation with numerical values of the parameters: density ρz = 1.2…1.5∙103 kg/m3, length lz = 5.0…10.0∙10-3 m, width b = 1.4…3.6∙10-3 m and thickness δ = 1.2…3.5∙10-3 m. Theoretical studies were carried out on the basis of methods of mathematical modeling, classical mechanics using the laws of hydrodynamics. It was found that when using in the machine for the isolation of toxic ergot sclerotia from the grain of an aqueous solution of salt with a density ρzh = 1000…1150 kg/m3 and a height h1 = 0.35…0.60 m in a bath, the total time ttotal of seeds residence varies within 7.6…18.8 s. During this time, the seeds are moistened superficially, to eliminate which it is enough to blow them under the pressure of atmospheric air.
