Abstract:
Apple is an open pollinated entomofilic fruit species. For successful fruiting, it is necessary to provide two or more varieties which are good pollinators, in addition to being compatible with the main cultivar. The situation is similar with the artificial pollination of apples with the aim of obtaining hybrid seeds, the only difference is that for this kind of pollination insects do not have to be provided. In order to create new varieties of apples, we selected the varity Ajdared as the recipient of pollen (mother) and Topaz, Rubies and Pink Lady, as pollinators varieties for which we do not have data how they act as pollinators or what kind of impact they have on the production of hybrid seed. Based on the obtained data, we concluded that the varieties pollinators in all combinations have a high impact on the production of hybrid apple seeds

Abstract:
Several kinds of rubbers used for fabric expansion joints were studied by Thermogravimetric analysis under inert atmosphere before and after artificial accelerated thermal aging. The results showed that because of the difference of the chemical structures, the rubber aging is different. And the thermal stability of Polytetrafluoroethylene (PTFE) was obviously higher than that of other two kinds of rubbers, ethylene-propylene-diene-terpolymer rubber (EPDM) and fluororubber.

Abstract:
Silicone rubbers are used for manufacturing fireproof insulating sheaths for cables and high voltage insulators. Highly oil-resistant silicone rubber of brand IRP 1338 of JSC “Kazan plant of synthetic caoutchouc” production should be singled out among silicone rubbers. This rubber is made from synthetic caoutchouc SKTV and contains Aerosil A-300, titanium oxide, fumed silica U-333 curing agent Perkadox BC-FF and anti-structuring agent ND-8 - α,ω-polydimethyl-siloxanediol. Previously we investigated the kinetics of combustion process of this rubber containing anti-structuring agent ND-8 as well as Ca/Zn-stabilizer Kompanoks (2,6-bis((3,5-di-tert-butyl-4-hydroxyphenyl)methyl)cyclohexane-1-one) and their combination which are used to enhance the thermal stability of the rubbers on the basis of carbon-chain caoutchoucs. In given paper using artificial neural networks (ANN) the computational multifactor model of combustion of rubber IRP 1338 has been obtained. The influence of selected stabilizers on the combustion rate of silicone rubber IRP 1338 has been studied. The combustion process was investigated by measuring at different points in time the relative height of the unburned portion of the rubber samples in the form of standard rectangular bars with a size of 10x2x2 mm. Combustion occurred under the action of the infrared beam (wavelength 10.6 μm) of laser LG-25 at three temperatures radiation (800, 900, 1000°C). As the main factors influencing the combustion of rubber, the laser radiation temperature was chosen, under which the forced combustion of rubber occurred. The nature of the stabilizers introduced into the rubber and the combustion temperature of the rubber was measured by a thermocouple placed on the surface of combustion rubber. The objective function of ANN-model was the relative height of the unburned portion of the rubber samples. Moreover, it was believed, the greater the relative height of the unburned portion of the rubber samples, the lower the burning rate and the higher the efficiency of the stabilizer. The received ANN-model has allowed to reveal three stages of combustion of rubber and to investigate features of influence of stabilizers on process of combustion. It was established that from the three stabilizers studied, the Ca/Zn stabilizer most effectively slows down the combustion of rubber due to the interaction of calcium oleates and zinc of this stabilizer with caoutchouc molecules. Thus, the possibility of increasing the fire resistance of rubber based on the silicone rubber SKTV by replacing the anti-structuring agent ND-8 on the Ca/Zn stabilizer has been established.Forcitation:Abrukov V.S., Efimov K.V., Tarasov N.A., Koltsov N.I.

Abstract:
In this study, artificial skin based on silicone rubber is introduced for a robot head of the same size and shape as an actual person. The artificial skin is described from designing to molding the skin for a robot head, which mimics a young woman’s head. Fabricated skin is different from regular masks because it has to cover the core mechanical systems and move together. Skin movements create emotions on the face and give the appearance of a robot head. The robot has the same expressive and oral capabilities as humans and is integrated with artificial intelligence platforms. The knowledge of head anatomy and the parameters of the operation of the head will be applied in the design and fabrication of core mechanical mechanisms and their covering skin. This study analyses the basic knowledge of skin anatomy as well as the fabricating steps to make artificial skin made of silicone rubber material. The knowledge of skin anatomy is the foundation to study and analyze the general characteristics of human skin such as elasticity, color, elasticity, etc. Manufacturing methods for artificial skin are researched and selected accordingly. Finally, the artificial skin is created to make the robot head’s expression more realistic. Experimental results showed that the robot meets design requirements, has an 89.83% accuracy rate of human identification of robot expressions, and is highly appreciated by users in interactive experiments.

Abstract:
As per sequential studies on new types of soft rubber for the artificial skin of robots, smart sensors, etc., we have proposed and investigated hybrid skin (H-Skin) and haptic sensors by using magnetic compound fluid (MCF), compounding natural rubber latex (NR-latex), and applying electric and magnetic fields. Through electrolytic polymerization, the MCF rubber is solidified. The MCF rubber has hybrid sensing functions and photovoltaic effects, and electric charge as battery. In case of the production of soft rubber sensors, however, the problem of adhesion between metal electrodes and rubber is very important. In the present study, we propose a novel adhesive technique for bonding the metal electrodes and MCF rubber by using metallic or non-metallic hydrous oxide, which is a metal complex, via electrolytic polymerization. The anionic radical hydrate reacts with the isoprene molecules of NR-latex or chloroprene rubber latex (CR-latex) such that they are cross-linked and the MCF rubber with the hydrate is solidified, which can be represented via a chemical reaction equation. By means of this adhesive technique, we presented five cases of sensors fabricated using metal electrodes and rubbers. This technique is applicable for novel cohesion between rubber and metal.

Abstract:
The article presents the tests results for the resistance of rubbers of three brands to mold fungi in natural atmospheric conditions and in laboratory conditions when they are artificially infected with spores. These results show that the intensity of development of fungi on the surface of rubbers is from 0 to 2 points with a norm of not more than 3 points. It has been determined that the strength properties of rubbers after exposure to mold fungi in laboratory and natural conditions are at the level of the initial ones. The paper provides the conclusion about the bactericidal properties of the components of rubber mixtures in relation to mold fungi.

Abstract:
This paper deals with the mechanism and control of a vertebral backbone system which operates on compressed air. This backbone system is composed of layered plates, balls, and artificial rubber muscles driven by pneumatics. The bending angle and direction of the backbone are fixed by displacement of wires that are connected to the artificial rubber muscles. In usual cases, a pair of artificial rubber muscles are used to operate a one-degree-of-freedom joint. This study proposes a mechanism and control method for a two-degreeof-freedom joint driven by three artificial rubber muscles. The structure of the backbone and its analysis in consideration of the characteristics of artificial rubber muscles are described. A control method and experimental results are also shown in this paper.

Abstract:
In recent years, soft robots, such as those with high human affinity and those that excellently imitate the movements of natural creatures, have gained considerable attention. In soft robots, structurally flexible soft actuators need to be used, not conventional motors or hydraulic/pneumatic cylinders. Various types of soft actuators have been developed depending on the driving principle. A pneumatic rubber artificial muscle is a kind of soft actuator that acquires power through injection of a working fluid, such as air, into an elastic structure, such as rubber. In this study, the authors developed an actuator, namely, the straight-fiber-type artificial muscle, which exhibits excellent contraction characteristics. This artificial muscle consists of a rubber tube that contains reinforcing fibers arranged in the axial direction. When air pressure is applied to the rubber tube, the artificial muscle expands only in the radial direction and contracts in the axial direction due to the restraining effect of the reinforcing fiber. While this artificial muscle exhibits excellent contraction properties, it has some drawbacks. One is the difficulty in enclosing the reinforced fibers that have accumulated in the rubber tube, making this artificial muscle difficult to manufacture. In this study, we investigated short-fiber-reinforced artificial muscles that can be easily manufactured. First, a short-fiber-reinforced rubber was prepared, and anisotropy was evaluated via a tensile test. Then, the short-fiber-reinforced artificial muscles were prepared, and their contractions rates were evaluated. The results confirmed that a short-fiber-reinforced rubber can be useful for the manufacture of artificial muscles.

Artificial  spider  webs  are  a  challenge  for  the  special  effects  companies.   The natural  spider webs  are  displaying  incredible  mechanical  properties  combined with  a  low  density  and  a  high stickiness making them hard to reproduce. Throughout this project the aim is to produce artificial spider  webs  using  a specific  manufacturing  method,  pouring  a  mix  of  polymer  and  Naphtha  oil into  water  to  form  the  webs.   This  method  was  used  in  previous  cinematic applications  giving outstanding results for the artificial spider webs.  Unfortunately, due to the loss of it, the specific parameters,  tools and raw materials have to be found.  A material selection is given leading to a specific choice of thermoplastic polymers.  The selected material are then tested manually so they can be listed depending on the results obtained.  Finally, the most promising material seems to be TPU, thermoplastic polyurethane;  thanks to its excellent mechanical properties and good visual aspect.

Abstract:
Loss of speech is one important factor which contributes to a decrease of life quality for patients who undergo larynx removal following for example advanced laryngeal cancer. Several devices such as the electrolarynx and the tracheo-esophageal valve prosthesis (without oscillation) have been commercialized in order to restore speech. However, such voice restoration prosthesis are still limited for certain patients. The development of a new device using a valve of variable resistance entrained by a linear electromechanical transducer was investigated as a way to produce speech for patients with total laryngectomy (ablation of vocal folds). The concept was to undertake the design of a varying air flow resistance valve, built around existing Blom-Singer valves. The oscillating valve features a spherical head making it possible to block the opening in the wall between the trachea and the esophagus in a sinusoidal periodic fashion. A physical model of the vocal tract was built and used for preliminary in-vitro verification studies. The relationship between pressure and flow rate through the valve was determined from pressure measurements. The orifice discharge coefficient of the orifice was then calculated and the parameters of a variable resistor model were identified. Radiated sound pressure produced from the change in flow rate at the valve orifice was then compared to the original voice output to assess the accuracy of the design prototype. Results showed that the forced oscillating valve prosthesis model has lower power efficiency but can produce better sound quality than the electrolarynx.

Abstract:
Tire-pavement interaction is a dominant noise source for passenger cars and trucks above 25 mph (40 km/h) and 43 mph (70 km/h), respectively. For the same pavement, tires with different tread pattern and construction generate noise of different levels and frequencies. In the present study, forty-two different tires were tested over a range of speeds (45-65 mph, i.e., 72-105 km/h) on a non-porous asphalt pavement (a section of U.S. Route 460, both eastbound and westbound). An On-Board Sound Intensity (OBSI) system was instrumented on the test vehicle to collect the tire noise data at both the leading and trailing edge of the tire contact patch. An optical sensor recording the once-per-revolution signal of the wheel was also installed to monitor the vehicle speed and, more importantly, to provide the data needed to perform the order tracking analysis in order to break down the tire noise into two components. These two components are: the tread pattern and the non-tread pattern noise. Based on the experimental noise data collected, two artificial neural networks (ANN) were developed to predict the tread pattern (ANN1) and the non-tread pattern noise (ANN2) components, separately. The inputs of ANN1 are the coherent tread profile spectrum and the air volume velocity spectrum calculated from the digitized 3D tread pattern. The inputs of ANN2 are the tire size and tread rubber hardness. The vehicle speed is also included as input for the two ANN's. The optimized ANN's are able to predict the tire-pavement interaction noise well for different tires on the pavement tested. Another outcome of this work is the complete literature review on Tire-Pavement Interaction Noise (TPIN), as an appendix of this dissertation and covering ~1000 references, which might be the most comprehensive compilation of this topic.

Abstract:
A Rubber Balloon Soil Densitometer is one of the essential apparatuses in Geotechnical Engineering to measure the in-place volume of compacted soil to calculate the soil density. In 2019, some renowned institutions and organizations, Vattenfall, Luleå University of Technology, Uppsala University, Lund University, and HydroResearch AB, were involved in a research project. As a part of that research project, a small earth-rockfill dam was built in Älvkarleby, Vattenfall. During the construction of the experimental dam, to test the sufficiency of the degree of compaction in the core layers, the Rubber Balloon Soil Densitometer of the German company called Headquarters of Magdeburger Prüfgerätebau GmbH, in short HMP, was used. However, it was suspected that some of the HMP densitometer test results showed measured volumes of the excavated holes lower than the expectation. Hence, it aroused the necessity to check the correctness of the balloon test apparatus and its test procedure. This thesis topic aims to fulfill that necessity. The objective of this research is to determine whether the volumetric measurements achieved by this apparatus are accurate. If the volumes measured by this apparatus are inaccurate, it is crucial to find the reasons behind the inaccuracy. It is also essential to determine the inaccuracy causes and pursue the solution to obtain precision in volumetric measurement. This thesis topic is vital for engineers and researchers of civil engineering and other departments because concluding the research would help collect better soil density data using an HMP Rubber Balloon Soil Densitometer and other similar densitometers. All the laboratory works of this thesis were conducted at the Soil Laboratory of Luleå University of Technology. At the beginning of the laboratory work, a pit was excavated in a compacted mixed fine-grained silty sand type of soil inside a bucket to conduct a densitometer test. The actual volume of this pit was determined using the water replacement method. The HMP densitometer measured a volume of this pit smaller than its actual volume. Then, the apparatus itself was tested to evaluate its function. It was found that the plexiglass cylinder has different inner circular cross-sectional areas at different heights, which do not match the inner circular cross-sectional area mentioned in the HMP sticker on the plexiglass. As time passes, slight deformation of a plexiglass cylinder is normal and can happen because of temperature, applied pressure, and repetitive usage. The precision in percentage from the actual volume of a pit indicates the stuck air between the pit surface and the rubber balloon during a densitometer test. For engineering purposes, a precision in percentage smaller than one percent can be considered reasonable. The results showed that the actual volume of a pit should be at least around one liter to achieve precision in percentage from the actual volume of the pit smaller than about one percent. Additionally, pits with larger actual volumes have smaller precision in percentages from the actual volumes of the pits. The imperfection of the plexiglass cylinder has a lesser influence on larger pits during a densitometer test. Compacted coarse-grained soil can absorb the stuck air during a densitometer test because of having a sufficient quantity of pores. However, compacted fine-grained soil is so airtight that the soil can not absorb the stuck air. Transparent bowls and non-transparent bowls and a bucket were considered artificial pits of different sizes and shapes in compacted fine-grained soil, and densitometer tests were conducted with them. The results showed that the extended Ucsan bowl had the appropriate shape and size among these artificial pits. Because the average percentage of stuck air inside it was the smallest. However, the topmost diameter of an artificial pit or a real pit should be the same as the inner diameter of the metal ring of the HMP apparatus. Putting two stripes of industrial cleaning cloth perpendicularly inside an artificial or a real pit during a densitometer test was considered a solution to the stuck air problem. After applying this solution for the densitometer tests with all the artificial pits, the results showed that a real pit's appropriate shape and size with this solution should be similar to the extended Ucsan bowl. This was proved at the end of the laboratory work when a pit was excavated through the metal ring of the apparatus in a compacted mixed fine-grained silty sand type of soil inside a bucket to conduct densitometer tests. This pit was given a shape and size similar to the extended Ucsan bowl during excavation. This time, two industrial cleaning cloth stripes were placed perpendicularly inside the pit before the tests. The results showed that almost all the stuck air could be dissipated during a densitometer test by placing two stripes of industrial cleaning cloth perpendicularly inside a pit with a shape and size similar to the Ucsan bowl. During laboratory work, the HMP apparatus continuously measured volumes smaller than the actual volumes in all the densitometer tests.

Abstract:
Vibrations are very common phenomenon. It influences structures and generates acoustic noise which might be harmful to human beings. The vibration isolator was invented to reduce the effect from vibrations. However, the behavior of rubber material, which many vibration isolators are made of, is hard to predict. Consequently, vibration tests are needed to obtain the dynamic properties of rubber isolator.In this case, a six-year old LORD 2204-5 rubber isolator provided by Atlas Copco was tested. The aim of this paper is to obtain the FRF (Frequency Response Function) diagram which can describe the property of the rubber material. Moreover, the influence of aging of rubber material on the dynamic properties was studied.As the vibration test should simulate the working environment of the isolators that are both a static load from the structure and a dynamic force from the engine, a new excitation method was designed. The camshaft with the shape of an epitrochoid induced the sinusoidal signal of the isolator and the frame transferred the static load from the hydraulic machine. The artificial aging was performed in a hot air oven in 90°C for 42 hours, which according to Arrhenius equation should be equivalent to six years of natural aging. The vibration isolator was tested again after being aged.The obtained data showed that the aging process decreased the stiffness of the material. The results were corresponding with other studies regarding aging of rubber.

Abstract:

In recent years the use of inflatable dams has become more widespread throughout the world. Various people have done studies on the shape and membrane tension of these structures; however, only a few authors have considered dynamic behavior. Due to the nature of the applications and the material composition of these structures, a study considering the dynamic response of an inflatable dam is warranted.

In this study, the equation of motion for an air-inflated dam is derived, then solved using the Galerkin approximation method. The solution is performed for a one-term approximation and a two-term approximation, where both solutions use a sine function to approximate the deflected shape of the dam. Frequencies and amplitudes are calculated and presented in tables and plots for the first four modes, and three different values of the central angle of the dam. Comparisons to the results of other studies are presented at the conclusion of this study.

Abstract:
Rubber granulates, used at artificial grass pitches, pose a threat to the environment when leaking into the nature. As the granulates leak to the environment through rain water and snow clearances, they can be transported by rivers and later on end up in the marine life. Therefore, reducing the snow clearances to its minimum is of importance. If the snow clearance problem is minimized or even eliminated, this will have a positive impact on the surrounding nature. The object of this project is to propose a method for deciding when to remove snow and automate the information dispersing upon clearing or closing a pitch. This includes finding low powered sensors to measure snow depth, find a machine learning model to predict upcoming snow levels and create an application with a clear and easy-to-use interface to present weather information and disperse information to the responsible persons. Controlled experiments is used to find the models and sensors that are suitable to solve this problem. The sensors are tested on a single snow quality, where ultrasonic and infrared sensors are found suitable. However, fabricated tests for newly fallen snow questioned the possibility of measuring snow depth using the ultrasonic sensor in the general case. Random Forest is presented as the machine learning model that predicts future snow levels with the highest accuracy. From a survey, indications is found that the web application fulfills the intended functionalities, with some improvements suggested.

Abstract:
The most frequent victims of fraudsters are minors and the elderly. According to VTsIOM statistics for 2020, fraudsters stole a total of about 150 billion rubles. In this regard, there is a need to develop means to protect the home. The paper presents a system that is a model of a smart home system using the capabilities of artificial intelligence and available technologies of today. The paper proposes a system, the principle of which is to obtain information from the outside, which is a model of controlling the functions of a smart house using the capabilities of AI. With the help of devices, the system monitors the state of the house and the well-being of its occupants, and further decision-making depends on the critical situation and the techniques embedded in it. Using the system will be possible through control through voice commands, which will allow you to fully focus on a comfortable and safe spending time in the house. The system functions with the help of "Crosscutting technologies", they are divided into collecting, transmitting/storing and analyzing/deciding.

Abstract:
The project assessed Guided Wave Technology (GWT).�Five off pipes were to be set up such that one was a clean control with no defects, and the remaining four marked up with artificial corrosion defects via Electrical Discharge Machining (EDM), which was used to create features considered typical of riser/pipeline damage. The pipes also had girth welds and weld neck flanges at each end as reference and calibration markers.
