Today I have read the article "Low pressure plasma arc source ion nitriding of austenitic stainless steel". A series of low pressure plasma arc source ion nitriding experiments has been conducted on AISI 304 stainless steel at temperatures ranging from 350 to 460°C in an N2–H2 gas mixture. The structure and composition of the plasma nitrided layers were studied by optical metallography, X-ray diffraction (XRD) and Auger electron spectroscopy (AES). The thickness of the nitrided layer depends on the plasma nitriding temperature. The hardness values of the nitrided layer measured are in the range of 4.6 GPa for the sample nitrided at 350°C to 12.0 GPa for the sample nitrided at about 420°C.

Today I have read the article called “Modern file input/output with Java: Going fast with NIO and NIO.2”.
The article is about achieving high performance in terms of file input/output. High performance here means not only the speed of I/O operations, but also minimal resource consumption. NIO (new input/output interface) brought many enhancements to I/O operations, such as files to RAM data mapping, nonblocking I/O operations, new regular expressions library, encoding and decoding of character sets, additional abstraction layer that do not require heap traversing. Also NIO introduces new entity called channels. It provides support for read and write operations for files and web sockets. For me the article was very interesting especially the code snippets that showed NIO abilities in practice. This knowledge can be used in my work projects.

Today I have read article called “Convolutional neural networks: an overview and application in radiology”.
Convolutional neural network (CNN), a class of artificial neural networks that has become dominant in various computer vision tasks, is attracting interest across a variety of domains, including radiology. CNN is designed to automatically and adaptively learn spatial hierarchies of features through backpropagation by using multiple building blocks, such as convolution layers, pooling layers, and fully connected layers. This review article offers a perspective on the basic concepts of CNN and its application to various radiological tasks, and discusses its challenges and future directions in the field of radiology.

TITLE: "Attention-Based Environment Perception in
Autonomous Robotics"
This paper describes a robotic architecture that uses visual attention mechanisms for autonomous navigation in unknown indoor environments. Navigation in unknown environments is one of the most fundamental subject in mobile robotic research. The authors have pick up the most complex way and in the same time the most rationallity way. They picked the biological model called like a foveation mechanism based on bottom-up gaze shifts. The method helps for robot to evaluate the space and ways. The authors obtained an interesting result, their models of robot is adaptive to diffetent environemnts and acting conditions. It is interesting because robots like this are very similar to humans or animals.

Today I have read article called “Understanding Generative Adversarial Networks (GANs)”.
Generative Adversarial Networks belong to the set of generative models. It means that they are able to produce / to generate new content. Naturally, this ability to generate new content makes GANs look a little bit “magic”, at least at first sight. Rooted in game theory, GANs have wide-spread application: from improving cybersecurity by fighting against adversarial attacks and anonymizing data to preserve privacy to generating state-of-the-art images, colorizing black and white images, increasing image resolution, creating avatars, turning 2D images to 3D, and more.

TITLE: "TWO MODULAR NEURO-FUZZY SYSTEM FOR MOBILE ROBOT NAVIGATION"
The paper consists of approach analyze how to implement navigation in robotic systems. There are many problems in theme, for example, robot action in curved surface. The authors define two modes: finding the way and riding on the pained line. The way finding mode kindly most interesting, because the auhors use not typycal approach. The robot creates a space map using vision module. This approach based on fusion sets which help to calculate the square of objects. One interesting thing, the space calculation works only with triangle figures bacause it is much faster in calculation, but result can have some errors.

Today I have read article called “LP-BERT: Multi-task Pre-training Knowledge Graph BERT for Link Prediction“.
Link prediction plays an significant role in knowledge graph, which is an important resource for many artificial intelligence tasks, but it is often limited by incompleteness. In this paper, author proposes knowledge graph BERT for link prediction, named LP-BERT, which contains two training stages: multi-task pre-training and knowledge graph finetuning. The pre-training strategy not only uses Mask Language Model (MLM) to learn the knowledge of context corpus, but also introduces Mask Entity Model (MEM) and Mask Relation Model (MRM), which can learn the relationship information from triples by predicting semantic based entity and relation elements. Structured triple relation information can be transformed into unstructured semantic information, which can be integrated into the pre-training model together with context corpus information.

Today I have read the article called "What's the Difference Between AR and VR?”.
Virtual reality (VR) and augmented reality (AR) have exciting potential in the future of gaming, marketing, e-commerce, education, and many other fields. Both technologies are known for their enriched experience that brings together a virtual world and the real one with enhanced, 3-D visuals. Although it can be easy to mix up the two, there are some significant differences. The distinctions between VR and AR come down to the devices they require and the experience itself:
- AR uses a real-world setting while VR is completely virtual;
- AR users can control their presence in the real world;
- VR users are controlled by the system;
- VR requires a headset device, but AR can be accessed with a smartphone;
- AR enhances both the virtual and real world while VR only enhances a fictional reality.

TITLE: "Cognitive Robotics and Control"
The author of the paper has gathered some information about current situation in cognitive robotics themes. The eight subtitles are defined. It is paper - review, but using this, we can find new interesting sources for research. By the way, he even has described future features in this theme. The one of the interesting thems from article for me is robotic platforms. The author sees that robotic systems will take their place in operating rooms, providing stability and acuracy during surgey. The other interstings destination of cognitive robotics are Natural-inspired solution, field-programmable Gate Arrays, Socio-technical systems. Should be noticed, we can create one more direction in sience by defined crossed themes.

Quantitative traceable temperature measurement using novel thermal imaging camera by Matthew J. Hobbs, Chengxi Zhu, Matthew P. Grainger, Chee Hing Tan, and Jon R. Willmott

This article tells us about thermal imaging cameras based on focal-plane array (FPA) sensors and shows their disadvantages, such as stray radiation, cross-talk and the calibration uncertainty of ensuring each pixel behaves as if it were an identical temperature sensor. Radiation thermometers, consisting of only one detector element, which can be optimized and calibrated, can eliminate these problems, but don’t allow you to make a temperature image of the measurement object. To overcome these shortcomings, a sub-pixel camera based on micromechanical systems, which is able to create images with a resolution of 160×120p with a diameter of 350mm with a low-temperature error of 0.5°C when measuring temperatures below 700°C.

Thermal Imaging Metrology with a Smartphone Sensor by Leigh Russell Stanger, Thomas Charles Wilkes, Nicholas Andrew Boone, Andrew John Samuel McGonigle and Jon Raffe Willmott

The author of the article evaluated the market for thermal imaging cameras and found out that most of them are expensive. This was the main factor behind the appearance of this article, which set the task of creating an ultra-low-cost thermal imaging system based on a smartphone sensor. As a result of the developments, it was possible to achieve a reduction in the cost of this device, as well as to save its profitability for both industrial and research applications. Also, an important factor in choosing this device was the achievement of the accuracy of 10 °C in the range from 700 °C to 1000 °C.

Presented an implementation of a probabilistic first-order logic called TensorLog, in which classes of logical queries are compiled into differentiable functions in a neuralnetwork infrastructure such as Tensorflow or Theano. This leads to a close integration of probabilistic logical reasoning with deep-learning infrastructure: in particular, it enables high-performance deep learning frameworks to be used for tuning the parameters of a
probabilistic logic.

Today I have read the article "Unsupervised Iterative Deep Learning of Speech Features and Acoustic Tokens with Applications to
Spoken Term Detection"

In this paper automatically discover high quality frame-level speech features and acoustic tokens directly
from unlabeled speech data. A Multi-granular Acoustic Tokenizer (MAT) was proposed for automatic discovery of multiple sets of acoustic tokens from the given corpus. Each acoustic token set is specified by a set of hyperparameters describing the model configuration. These different sets of acoustic tokens carry different characteristics for the given corpus and the language
behind, thus can be mutually reinforced. The multiple sets of
token labels are then used as the targets of a Multi-target Deep Neural Network (MDNN) trained on frame-level acoustic features. Bottleneck features extracted from the MDNN are then used as the feedback input to the MAT and the MDNN itself in the next iteration.

Today I have read the article called “Experimental Characterization of Low-Speed Passive Discharge Losses of a Flywheel Energy Storage System”. Due to the intermittent behavior of wind and solar power generation, significant energy storage capacity is required to satisfy demand. In the article, measurements are presented for complete discharge experiments using a flywheel system featuring a vacuum enclosure. Using the study results authors formulated the measures for maintaining low-pressure environment in the flywheel. For me the most useful part of the article was not the results, but the process of experiment preparation and proper formulation of the conditions in mathematical form.

Today I have read the article "Theory of non-reciprocal flow could lead to new quantum devices". A new theory describing how energy and information could be made to flow in one direction around a cluster of three interacting quantum systems has been developed by Charles Downing at the University of Exeter and David Zueco at the University of Zaragoza. The scientists have designed a more general theoretical description of a quantum trimer based on a triangular cluster of two-level quantum systems.
Their results pave the way for new experimental studies of nanoscale directional currents, which could lead to the development of new ways of controlling the flow of energy and information. The research could also lead to new studies of exotic states of matter that feature strongly interacting quantum systems.

Today I have read the article "Complex numbers are essential in quantum theory, experiments reveal". The two independent teams of physicists have devised two separate experiments to test the importance of complex numbers for quantum theory. One team was led by researchers at the Institute for Quantum Optics and Quantum Information; and the other team by scientists at the University of Science and Technology. Both experiments started with a so-called “Bell game”. Neither of the three was an actual person, but instead they were part of a complex measurement protocol. One player is on “team complex quantum physics” while the other plays for “team real-valued quantum theory”. Having shown that complex and real quantum physics can be definitively distinguished in light-based and superconductor-based settings, the researchers are now exploring more precise experiments in both systems.

Few days ago, I read the article called “Conformal Wireframe Nets for Trimmed Symmetric Unit Cells in Functionally Graded Lattice Materials”. Tessellating a periodic unit cell of lattice material to fill a design space in complex geometries has many challenges arising from their computer-aided design (CAD) modeling intricacy. Due to the complexity of the micro-structure of truss lattice materials, where it involves a huge number of elements, the possibility of solving all underlying equations in full detail is computationally expensive and might be impossible. The lattice net generation algorithm contains five stages. The article was useful for me because the provided algorithm may be combined with thermal field distribution model for different material types.

Today I have read the article called «Environmental regulations, innovation and firm performance: a revisit of the Porter hypothesis» written by Ram Ramanathan, Andrew Black, Abby Ghobadian and other. Environmental regulations can play an important role in limiting the harmful effects of economic activity on the natural environment; however, they can also impose a significant cost on businesses. If environmental regulations specify that any company wishing to produce a particular product or substance must use a certain technique to reduce its pollution, then the company is forced into paying for the pollution control equipment. It was very interesting to me.

Today I have read the article called «Measuring economic insecurity: a review of the literature» written by Matteo G. Richiardi and Zhechun He. While there is ample evidence that economic insecurity is an important feature of our times, its quantification remains elusive and controversial, in stark contrast with the vast amount of knowledge that has been accumulated on related concepts like poverty and inequality. Economic insecurity is a complex concept involving risks and hazards over many dimensions, so it is in a sense unavoidable that a summary measure will not be able to provide a complete picture. It was very informative to me.

TITLE: "Artificial intelligence: from metaphor to technical solution"
The future artificial intelligence (AI) should have elements of cognitive computing in future. It will lead to solving high-load and uncontrollable tasks. The authors have noticed one important thing that cognitive computing requires big computational costs.
They compare the human persepton with technical analog. For now, we dont have such effective operational components.
But still, the future cognitive systems should handle typical and already known operation, like logical operations, aggregations, recognition but using them with big data context.
The authors have reviewed the another architectures to resolve weak processors problem. They have provided some prototype in code using emperative paradigm which means that the problem always exists for cognitive system.

The authors describe cognitive computer systems like not typical technical systems. The cognitive computing can no be realized by architectures which we have for today. They require another approach. The approach which offer the implementation of many fetures from human psycology: problem solving, memory, attention, perception, language.
The authors has determinated that in cognitive computer systems the basic conceptions should be established. They should implement animal brain with certain borders and limits. My line related with human cognition and reflection.
The authors provide structure schema of abstract cognitive system which consists of database, planing operations, realization of planing operations, sensors, technical eyes, speech understaning.

TITLE: "Application of Filters with Similar Type in Analog and Digital
Signal Processing Paths in Robotic Systems"
The authors offer to decompose high-order components on chain. The main idea is an use the same type low-order components for creating more higher. The components are linked one by one. It should lead to easy development because the low-order elements much more simpler to calculate.
This idea is directed for signal processing paths. The signal processing path is an element between sensors and main systems. It convert analog signals into digital with other important operations related with filtering, stabilisating, amplificating of analog signals. The signal procressing path is one of the main part of adaptive module in cognitive computer systems.

TITLE: "The context types in different science approaches"
The paper considers about certain essential of "context" word. It is not technical paper, but it is important for themes concerned with text recognition. From the article we can find out the main types of context: culture context, current situation context, internal context, micro/macro context. For the cognitive computer systems is very important theme of current situation context. Future robotic system should have control about current situasion.
The authors determine entety of this word. This article makes me think how the robotic systems can comunicate with other. By settings, behavior environments, extra-situations they need to plant many contexts and generate some actions.

The Statistical Power and Confidence of Some Key Comparison Analysis Methods to Correctly Identify Participant Bias by Ellie Molloy, Annette Koo, Blair D. Hall and Rebecca Harding.
In this article authors show us some statistics about the method that can be interesting for Consultative Committees. The model that is shown in this paper with the largest consistent subset delivers the highest statistical power under conditions likely to prevail in mature technical fields, where most participants are in agreement and calibration and measurement capability claims can reasonably be supported by the results of the comparison. Also, it can be easily implemented for other scenarios or analyses or choice of measurement methods in various measurement areas in industry.

An Overview of Acoustic Impedance Measurement Techniques and Future Prospects by Nandeesh Hiremath, Vaibhav Kumar, Nicholas Motahari and Dhwanil Shukla
This paper shows us acoustic impedance measurement techniques and future prospects. In the head of acoustic measurements – is acoustic Impedance. acoustic impedance means a measure of the opposition of acoustical flow due to acoustic pressure. By this measure we can decide how much pressure is generated by the vibration of molecules of a particular acoustic medium at a given frequency also it can be a characteristic of the medium. Here we get three main impedance measurement techniques:
1. Reverberation chamber techniques.
2. Impedance tube techniques.
3. Far-field techniques.
All of these methods have their own history, pros and cons.

Non-fungible token become a more and more popular topic. This is the next step in ownership. Previously it was possible to be an owner only for physical or intelligent things, but now the same is possible with digital artifacts. It can be applicable for many segments like games, digital arts, digital collections. New startups based on NFT are funded more often and raise bigger funds compared to others, this shows us how interesting current topic to the investors. There is only one issue that I see - technology locked to the blockchain technology that can be a blocker for a good scaling in the future. The article briefly explains what is NFT and how it can be used, it can be useful for beginners who are interested in it. For a more deep understanding, more specific materials should be used.

Also I have read the paper "Plasma and ion sources in large area coating: A review". Efficient deposition of high-quality coatings often requires controlled application of excited or ionized particles. The article starts by looking at a number of particle-induced effects because they form the basis for the selection of hardware components and process parameters. These particles are either condensing (film-forming) or assisting by providing energy and momentum to the film growth process, resulting in densification, sputtering/etching, modification of stress, roughness, microstructure, texture, etc. Characteristics and differences between plasma and ion sources are explained. The latter include gridded and gridless sources. Special cases like plasma immersion treatment are also briefly mentioned.

Also I have read the article "Synthesis of Multilayer Vacuum Ion-Plasma Coatings Ti-Tin during the Surface Modification". The article presents the results of the technology development for the vacuum ion-plasma coating deposition with the additional ionic bombardment. As a method to realize the additional ionic bombardment, use of the hollow cathode effect or non-self-maintained high-current discharge generated by the plasma source with an incandescent cathode is suggested. The results show the presence of carbide and nitride ceramics phases contribute to high microhardness and wear resistance. The multiple-needle-cathode discharge plasma treatment is an effective method for improvement of the mechanical and tribological properties of titanium-base alloys by formation of graded diffusion hard surface layers. The technology of synthesis of protective coatings with the submicrocrystalline structure was developed.

Today I have read the article "Multi-objective equilibrium optimizer: framework and development for solving multi-objective optimization problems". This arlicle proposes a new Multi-Objective Equilibrium Optimizer (MOEO) to handle complex optimization problems, including real-world engineering design optimization problems. The Equilibrium Optimizer (EO) is a recently reported physics-based metaheuristic algorithm, and it has been inspired by the models used to predict equilibrium state and dynamic state. An archive with an update function is used to uphold and improve the coverage of Pareto with optimal solutions. From the results obtained for all 33 benchmark optimization problems, the efficiency, robustness, and exploration ability to solve multi-objective problems of the MOEO algorithm are well defined and clarified.

3D Temperature Distribution Model Based on Thermal Infrared Image by Tong Jia, HongYu Wang, DongYue Chen, MingYa Hou, ChengDong Wu, Mo Tu, Yuli Jiang, and Shuai Zhang
This article tells us about the 3D temperature distribution reconstruction system based on binocular vision technology. This method used binocular vision to create a 3D map (point cloud), which can help to create a 3D thermal map of the explored object. But unfortunately, standard methods of calibration became useless, so we need to calibrate the infrared camera apart from binocular vision. Also, we need to minimize ping between creating 3D point cloud and thermal vision to create a truly 3D temperature distribution model.

Today I have read the article "Increasing the efficiency factor of solar power plants due to solar energy localizing."
The article presents an analysis of the state of development of solar energy in Europe and the Republic of Belarus for 2020. An algorithm for increasing the efficiency factor of solar power plants by localizing the solar trajectory depending on the latitude and longitude of the area has been proposed. In particular, taking into account the angle of the Sun position above the horizon and the azimuth angle of the Sun, the increase in the efficiency factor of solar power plants for the Republic of Belarus is calculated. Based on this algorithm, a program has been written that makes it possible to draw a diagram of the solar trajectory. An analysis has been made of the degree of localization of solar energy for solstice days in 6 oblast (regional) centers of the Republic of Belarus; it is found that the highest intensity of solar radiation is observed in Brest and Gomel, the average in Grodno, Minsk and Mogilev, while the lowest one – in the city of Vitebsk.
The obtained numerical calculations of the solar trajectory make it possible to optimize the orientation of solar panels for permanently installed panels and for automated solar tracking systems, as well as to select the optimal configuration of the power plant equipment for any geographic area.

Today I have read the article called "Using solar batteries in modern conditions."
The article considers the efficiency of using solar panels. The condition under which their effectiveness is maximal is analyzed. Considerable attention is paid to the prospects for the development and use of solar cells. The cost of 1 kilowatt - hour of electricity generated by solar energy is comparatively comparable to that produced by traditional stations. The problems and deficiencies of energy resources, and their influence on the work of power stations are considered. The advantages of using solar power plants are emphasized. The disadvanteges of solar power stations are briefly reviewed.

Yesterday I read the article called “Mechanical Properties of Selected Epoxy Adhesive and Adhesive Joints of Steel Sheets”. Adhesive joints are classified as non-detachable bonded joints. Adhesives are used not only to joint elements, but often the use of adhesive is to seal various elements, e.g., threaded joints. The aim of the article is to study the mechanical properties of epoxy adhesive of different epoxy resin/curing agent ratios (within and above the recommended stoichiometric ratio) and their effect on mechanical properties of adhesive joints of steel sheets. The article was useful for me because the study results can be used to make precise models of heat dispersion in such kind of joints.

Today I have read the article "Information Diffusion In Interconnected Heterogeneous Networks"

In this paper, interested in modeling the diffusion of information in a multilayer network using thermodynamic diffusion approach. State of each agent is viewed as a topic mixture represented by a distribution over multiple topics. Observation and learned diffusion-related thermodynamical patterns in the training data set, and using the estimated diffusion structure to predict the future states of the
agents. A priori knowledge of a fraction of the state of all agents changes the problem to be a Kalman predictor problem that refines the predicted system state using the error in estimation of the agents.

Today I have read the article "Information-Flow Matting"

Presenting a novel, purely affinity-based natural image matting algorithm. Method relies on carefully defined pixel-to-pixel connections that enable effective use of information available in the image. Controls the information flow from the known-opacity regions into the unknown region, as well as within the unknown region itself, by utilizing multiple definitions of pixel affinities. Among other forms of information flow, introduce color-mixture flow, which builds upon local linear embedding and effectively
encapsulates the relation between different pixel opacities.

Today I have read the article "Diamond quantum sensor breaks new record". The scientists of Harvard University use a new measurement scheme employing quantum sensors in diamond to realize a 100X improvement in NMR spectral resolution under ambient conditions for a sample volume comparable to that of a single cell – about 10 trillionths of a litre. The breakthrough allows researchers to perform NMR chemical analysis at the scale of single biological cells for the first time. According to the researchers, with further improvements in sensitivity, it might even allow for NMR spectroscopy of small molecules and proteins at the single-cell level. Dirk Englund of the Massachusetts Institute of Technology, who was not involved in this work says that the new study is an “amazing advance” in the field of quantum sensing.

Today I have read the article "Quantum sensor targets gravity and magnetism". Physicists in Australia have made a high-precision sensor, that can measure gravitational and magnetic fields at the same time. The device uses an atom interferometer to track the motion of a Bose–Einstein condensate (BEC) in free fall. The advantage of using a BEC is that the waves of the constituent atoms remain coherent across the full width of the cloud, which is several millimetres across. This makes it easier to achieve the overlap needed between the two paths of the interferometer to achieve a given sensitivity – thereby allowing the device to work in noisier environments. The scientists believe, that a portable version of the new sensor “will be interesting for geology and the prospecting of resources”.

Today I have read the article called «The concept of sustainable development: from its beginning to the contemporary issues». Sustainable development should provide a solution in terms of meeting basic human needs, integrating environmental development and protection, achieving equality, ensuring social self-determination and cultural diversity, and maintaining ecological integrity. Although the concept of sustainable development has undergone certain changes during the past, its fundamental principles and goals have contributed to a more conscious behaviour adapted to the limitations of the environment. This is the reason of adopting the concept in different areas of human activities. It was very informative to me.

Today I have read the article called «Sustainable development and human development. Evolution or transition in the scientific conception of sustainability». The human development paradigm is concerned with developing human capacities through a framework for growth and employment. Human development has four pillars: equity, sustainability, productivity and empowerment. It considers economic growth as essential, but emphasizes the need to pay attention to quality and distribution; it carefully analyses their link to the lives of people and questions their long-term sustainability. Economic growth is the engine of development and social progress, presented as the instrument and the purpose of development. It was very interesting to me.
