Abstract:

The manufacture of forgings to precise dimensional form and with specified mechanical and metallurgical properties has been the aim of industry since the industrial revolution. Developments towards this objective have been continual over the years as companies have sought commercial advantage in markets where competition from other industries such as foundry, powder metallurgy, sheet metal and fabrication is increasingly fierce. This paper starts with a brief review of historical milestones in the development of forging up to the first half of the twentieth century. The last 50 years have been a period of great activity in the establishment of a science base for forging technology and the development of cold, warm and hot processes with associated equipment to enable industry to provide components of greater complexity, increasing accuracy and nearer to net shape and research in the present author's laboratory has contributed to the advances in many areas. The major thrusts have dealt largely with improved tool designs and coatings for greater accuracy and longevity, techniques to enable metal to flow into die cavities of complex geometries and methods for complete process control, from raw material to product despatch. This paper attempts to highlight significant aspects of the technological developments which have been the result of world-wide activities. To give a coherent picture the steps of knowledge acquisition which have supported technological advancement are described using mainly the results of work from the present author's laboratory.

Abstract:

Precision engineering is a relatively new name for a technology with roots going back over a thousand years; those roots span astronomy, metrology, fundamental standards, manufacturing and money-making (literally). Throughout that history, precision engineers have created links across disparate disciplines to generate innovative responses to society's needs and wants. This review combines historical and technological perspectives to illuminate precision engineering's current character and directions. It first provides us a working definition of precision engineering and then reviews the subject's roots. Examples will be given showing the contributions of the technology to society, while simultaneously showing the creative tension between the technological convergence that spurs new directions and the vertical disintegration that optimizes manufacturing economics.

Abstract:

Introduction. The article is devoted to the problem of the crankshafts quality of automotive tractor engines on the example of YaMZ - 238NB engines. Despite years of experience in the repair industry to implement the technological process of the crankshafts grinding during their restoration, the quality of its implementation is not sufficient. Therefore, for reducing errors in restoring crankshafts, as well as in any other parts, it is possible only if the reasons for their occurrence are promptly identified. The purpose of the research is to identify the reasons of the errors in the process of grinding crankshafts for repair dimensions according to the results of technical control and observation of the technological process.Materials and methods. The methodological basis for experimental and theoretical research is a system analysis. The structural and functional representation of the object is also used for research, and the model for the analysis of the grinding process serves as the basis for the decomposition.Results. While analyzing the measurements results of the rod necks connection and polishing for repair dimensions, the transformed experimental-statistical method is applied. The peculiarity of the method consists in the algebraic transformation of the calculation algorithm, which is reduced to simple formulas for semi-finished products and which makes it easy to program calculations on the computer. In addition, the order of processing the number of obtained numerical values and construction of distribution curves is stated for estimating the correspondence between the probability of the experimental distribution and the theoretical distribution.Discussion and conclusions. The implementation of the algorithm for calculating the accuracy and stability for the technological process of grinding the crankshafts during their restoration would reduce the error value. Moreover, the reduction of errors during the process of crankshafts restoration would improve the quality of repair, thus prolonging the crankshaft serviceability.

Abstract:

It is desirable that the precision of the shape and the dimension of stone products in top grade decoration is getting higher. Grinding is one of the main technology in machining stone which ensures the precision of the shape and the dimension of stone products, and influences the machining efficiency. This investigation aims to experimentally find out the reasons causing grinding wheel wear and the factors influencing smoothness. It is found that the wear of grinding wheel is mainly caused by the hardness and removal quantity of stone. The harder the stone, the shorter the life of grinding wheel. The greater the removal quantity of stone, the bigger the wear of grinding wheel. The surface smoothness of stone is mainly related to the size of abrasives and the spindle speed. The smaller the abrasives and the higher the speed, the higher the smoothness.

Abstract:

Purpose Circumstances that are have a significant impact on it. In particular, environmental sustainability related to the increase of worldwide population, and market demand for agricultural products (with consumers more and more aware about cultivation and breeding techniques and interested in healthy and high-quality products) represent two of the key challenges that the agricultural sector is going to face in next years. In such a landscape, technological innovations that can support organizations and entrepreneurs to face these problems become increasingly important, and Industry 4.0 is the most striking example. Indeed, the Industry 4.0 paradigm aims to integrate digital technologies into business processes to raise productivity levels and to develop new business models. Accordingly, digital technologies play a similar role in the precision agriculture domain, and the purpose of this paper is to understand if the technologies at the basis of these two paradigms are the same or not. Design/methodology/approach The present work investigates how the two domains of Industry 4.0 and precision agriculture are connected to one another by analyzing the most used technologies in both the fields in order to highlight common patterns and technological overlaps. To reach such goal, an approach combining manual and automated analysis was developed. Findings The research work generated three main results: a dictionary of precision agriculture technologies including 324 terms; a graph, describing the connections between the technologies composing the dictionary; and a representation of the main technological clusters identified. Originality/value These show how the two domains under analysis are directly connected and describe the most important technologies to leverage when approaching digital transformation processes in the agricultural sector.

Abstract:

Surface size, geometry and texture are some of the most influential subjects in the fields of precision and ultra-precision engineering, defining the functional interface through which emerging products operate. Next-generation products demand super-smooth surfaces, freeform geometries or even deterministically introduced microstructures to provide functional performance. Technological progress using these surfaces types is possible only if the associated manufacturing processes are rigorously controlled and the surfaces are measurable. Metrology for advanced surfaces is not established. The current state of the art is challenged in respect to (i) surface characteristics, extremity of size, ultra precision, quality, geometric complexity, or combinations of these aspects, and (ii) measurement technology for the manufacturing environment, in particular, online, non-contact, high speed, ease of use, small footprint and robustness. This study addresses the challenges in this subject area and discusses some fundaments and principles derived from interdisciplinary research. The combination of these aspects is enabling the creation of manufacturing-environment-based measurement technology. This is expected to facilitate advanced surface manufacture over a wide range of sectors, including large science programmes and high-technology engineering.

Abstract:

To obtain homogeneous genetic seed of sunflower parent components, which by varietal and sowing qualities, must have a varietal purity of 99.6-99.9%, it is necessary to ensure their precise (exact) separation according to the morphological and physico-mechanical properties in the complex. Based on the necessary requirements for the technological processes of cleaning and separation of seed mixture, a rational precision technological line has been developed for the processes of separation of seed material of sunflower, which includes automation of technical equipment. Also, to increase the efficiency of the sunflower breeding process, a device for automatic phenotyping of seeds has been added to the developed production line, which makes it possible to significantly intensify and reduce the selection process and improve the design of the crossing program due to bioinformative data analysis and sorting of seeds. As a result of the analysis of technological methods for the separation of sunflower seed material and their technical support, it has been established that the main trends in the development of precision seed cleaning equipment are the creation of adaptive control systems that allow dynamic optimization of operating modes of the working bodies without operator intervention.

Abstract:

Currently, the influence of program documents on digital agriculture development is rather great in our country. Within the framework of the European Association of Agricultural Mechanical Engineering, a relevant definition of agriculture 4.0 has been elaborated and introduced.Research purpose: offering general recommendations on the digitalization of agriculture in RussiaMaterials and methods. The authors make use of the normative approach: the core of digital agriculture is compared with the current state of the agricultural sector in Russia.Results and discussion. The analysis has found that digital agriculture (agriculture 4.0 and 5.0) is based on developed mechanized technologies (agriculture 2.0), precision agriculture technologies (agriculture 3.0), the use of such digital technologies and technical means as the Internet of things, artificial intelligence, and robotics. The success of introducing digital agriculture depends on the success of all the three levels of the system. However, the problem of the lack of agricultural machinery indicates insufficient development of mechanized technologies; poor implementation of precision agriculture technologies means the lack of experience of using these technologies by the majority of farms in our country; an insufficient number of leading Russian IT companies (such as Amazon, Apple, Google, IBM, Intel, Microsoft etc.) weakens the country’s capacity in making a breakthrough in the development of the Internet of things, artificial intelligence, and robotics.Conclusions.The authors have identified the need to form scientific approaches to the digitization of technological operations used in the cultivation of agricultural crops and classified precision agriculture technologies. They have underlined that the digitization of agricultural production in Russia must be carried out along with intensified mechanization (energy saturation); also, to introduce technologies of precision agriculture and digital agriculture, it is necessary to organize state-funded centers for training farmers in the use of these technologies. Finally, it is necessary to take measures to strengthen the development of the IT sphere, as well as formulate an integral approach to the problem of digitalization.

Its value is noting that the farmers have long leveraged the technological breakthroughs and to adapt agricultural practices to ever-changing in times and this era is no exception, significantly with the emergency of fine Agriculture. Advanced commercial enterprise is fully dependent on power to efficiently manage resources so as to cut back the environmental impact, minimize the price and maximize the yield. Farmers are facing the associate degree interconnected to host of challenges and thus, having interest in incorporating the innovative technological solutions. Harnessing technology to alter precision agriculture has emerged to produce farmers with the tools they need to serve a half-hour larger population within the future in a very property approach that's harmonical with nature. The wireless sensor network (WSN) is a technology that has quickly been evolved over the years by enabling the spectrum of applications like industry, military, and agriculture. The LoRa devices have provided the ability to mechanically monitor the crops and the animals, which further provides the profitable knowledge which has been collected manually. During this project we tend to come up with a technology, to form a wireless network and alter the irreversible consequences of poor irrigation management. By dispersing the sensors that are connected to the phones or computers of the farmers will instantly receive the data on soil moisture and temperature, weather and rain, crop growth, and also receive the alerts on fire or theft and will activate irrigation instrumentation. All the data collected can feed into call management tools that helps the farmers to take the correct call at the correct time to get optimized results and will guarantee the property of his farm so high price knowledge are often transmitted over distances of up to fifteen metric linear unit from the sensors whose batteries which is lasting up to 10 years, leading to lower the maintenance and in operation prices beside the larger operational visibility, that successively empowers farmers to build their businesses.

Abstract:

Abstract: Technological advancements such as the Internet of Things (IoT) and Artificial Intelligence (AI) are helping to boost the global agricultural sector as it is expected to grow by around seventy percent in the next two decades. There are sensor-based systems in place to keep track of the plants and the surrounding environment. This technology allows farmers to watch and control farm operations from afar, but it has a few limitations. For farmers, these technologies are prohibitively expensive and demand a high level of technological competence. Besides, Climate change has a significant impact on crops because increased temperatures and changes in precipitation patterns increase the likelihood of disease outbreaks, resulting in crop losses and potentially irreversible plant destruction. Because of recent advancements in IoT and Cloud Computing, new applications built on highly innovative and scalable service platforms are now being developed. The use of Internet of Things (IoT) solutions has enormous promise for improving the quality and safety of agricultural products. Precision farming's telemonitoring system relies heavily on Internet of Things (IoT) platforms; therefore, this article quickly reviews the most common IoT platforms used in precision agriculture, highlighting both their key benefits and drawbacks

The technological manipulation of the piezo-electric actuator could compensate for the errors of the machining precision during the process of machining which lead to an elevation and enhancement in overall precisions. This manipulation is a very convenient method to advance the precision for nations without the solid knowledge of the ultra-precision machining technology. There were 2 divisions of researches conducted to develop the UPCU for precision enhancement of the current lathe and compensation for the environmental errors as shown below; The first research was designed to measure and real-time correct any deviations in variety of areas to achieve a compensation system through more effective optical fiber laser encoder than the encoder resolution which was currently used in the existing lathe. The deviations for a real-time correction were composed of followings; the surrounding air temperature, the thermal deviations of the machining materials, the thermal deviations in spindles, and the overall thermal deviation occurred due to the machine structure. The second research was to develop the UPCU and to improve the machining precision through the ultra-precision positioning and the real-time operative error compensation. The ultimate goal was to improve the machining precision of the existing lathe through completing the 2 research tasks mentioned above.

Abstract:

Since the inception of their profession, neurosurgeons have defined themselves as physicians with a surgical practice. Throughout time, neurosurgery has always taken advantage of technological advances to provide better and safer care for patients. In the ongoing precision medicine surge that drives patient-centric healthcare, neurosurgery strives to effectively embrace the era of data-driven medicine. Neuro-oncology best illustrates this convergence between surgery and precision medicine with the advent of molecular profiling, imaging and data analytics. This convenient convergence paves the way for new preventive, diagnostic, prognostic and targeted therapeutic perspectives. The prominent advances in healthcare and big data forcefully challenge the medical community to deeply rethink current and future medical practice. This work provides a historical perspective on neurosurgery. It also discusses the impact of the conceptual shift of precision medicine on neurosurgery through the lens of neuro-oncology.

Abstract:

In the era of precision medicine, it is crucial to identify molecular alterations that will guide the therapeutic management of patients. In this context, circulating tumoral DNA (ctDNA) released by the tumor in body fluids, like blood, and carrying its molecular characteristics is becoming a powerful biomarker for non-invasive detection and monitoring of cancer. Major recent technological advances, especially in terms of sequencing, have made possible its analysis, the challenge still being its reliable early detection. Different parameters, from the pre-analytical phase to the choice of sequencing technology and bioinformatic tools can influence the sensitivity of ctDNA detection.

Abstract:

The article highlights the design process aimed to develop a non-existing object, which should correspond to all the requirements. As far as the physical creation of an object is started only after finishing the design process, the whole procedure includes discussing different models and information. The result of sea terminals design is the documentation which consists of not only the necessary for construction and exploitation information, but also almost all physical, operational, exploitation and financial parameters of the object. The elements of behavior research, i.e. exploration of the output parameters reaction to the change of input ones and the data that were calculated on the previous steps of the design process, is a necessary part of each next step. The variation of requirements to the precision, sustainability and specification of data on different steps of design require to use different in complexity and precision models to analyze them. The capitalization of infrastructural objects of sea transport, the acceptance of liquidity and the scale of social-economic impact on the society define the special requirements to this branch of activity, which are applied in strict regulation and formulation of rules of all design processes. It has been stated that the active rules define the methods of sea terminals design, but this definition has been unchanged for a long time. The great evolution of nature, structure and volumes of data bring a conflict with the documental requirements to the calculations. There are developed the general rules of mathematical modelling used as an instrument of design on different steps of sea terminals design. There is carried out a brief content analysis of the typical steps of a design process, which allows to correspond the consequence of technological design stages with using the statistical modelling and queueing theory design methods. It also includes the description of a new concept of simulation modelling, which allows to connect gnoseological advantages of this approach with universality of traditional methods. Saving the universality and objective process of consequent adequacy provement of all the described models allow to put a question of utilization of this instrument into the general rules and recommendations of sea terminal design.

Abstract:

Improving the technologies and equipment at a stage of the blank production in mechanical engineering greatly determines the reduction in the technological production costs. The use of modern technological complexes on cutting sheet materials provides a solution to tasks for increasing the accuracy of forming. Nowadays high-precision plasma cutting is developing. It can be considered as an alternative to the laser cutting in achieving high characteristics of the cut accuracy and quality. The paper under consideration presents the results of optimizing the processing speed for the existing schemes of high-precision plasma cutting in the range of the cut thickness from 1 mm to 30 mm for carbon steel, alloy steel and aluminum steel. The efficiency of using the technological scheme HiFocusplus for cutting such bimetallic compositions as “steel St3 + steel 12H18N10T”, “steel St3 + aluminum A5M”, “steel St3 + copper M1” is presented. It is determined that the best characteristics of the accuracy and quality of the cut are achieved in cutting the composition “steel ST3 + steel 12H18N10T” from the side of low-carbon steel. Cutting from the side of aluminum and copper respectively is optimal for such compositions as “steel St3 + aluminum A5M” and “steel St3 + copper M1”.

Abstract:

It is one of the main topical objective to establish the conditions of sustainable farming. The sustainable development in crop production also calls for the harmony of satisfying human needs and providing the protection of environmental and natural resources; therefore, the maximum consideratio of production site endowments, the common implementation of production needs and environmental protection aims, the minimum load on the environment and economicalness. Precision farmin encompasses the farming method which is adjusted to the given production site, the changing technology in a given plot, the integrated crop protection, cutting edge technologies, remote sensing, GIS, geostatistics, the changeof the mechanisation of crop production, and the application of information technology novelties in crop production. Modern technology increases efficiency and reduces costs. The efficiency of crop production increases by reducing losses and the farmer has access to a better decision support information technology system. In addition, we consider it necessary to examine the two currently most important economic issues: “is it worth it?” and “how much does it cost?”. During the analysis of agricultural technologies, we used the precision crop production experiment database of KITE Zrt. and the Institute for Land Utilisation, Regional Development and Technology of the Centre for Agricultural and Applied Economic Sciences of the University of Debrecen.During our analytical work, we examined three technological alternatives on two soil types (chernozem and meadow). The first technology is the currently used autumn ploughing cultivation. We extended our analyses to the economic evaluation of satellite navigationassisted ploughing and strip till systems which prefer moisture saving. On chernozem soil, of the satellite-based technological alternatives, the autumn ploughing cultivation provided higher income than strip till. In years with average precipitation supply, we recommend the precision autumn ploughing technological alternative on chernozem soils in the future. On meadow soil, the strip till cultivation technology has more favourable economical results than the autumn ploughing. On soils with high plasticity – considering the high time and energy demand of cultivation and the short amoung of time available for cultivation – we recommend to use strip till technologies.

Abstract:

Novel technologies labelled as ‘precision medicine’ are targeting all aspects of clinical care. Whilst some technological advances are undeniably exciting, many doctors at the frontline of healthcare view precision medicine as being out of reach for their patients. Model-informed precision dosing (MIPD) is a precision medicine technology that predicts drug concentrations and drug responses based on individual patient characteristics. In this opinion piece, the example of MIPD is used to illustrate eight features of a precision medicine technology less likely to be hyperbole and more likely to improve patient care. Positive features in this regard include: (1) fitting the definition of ‘precision medicine’; (2) addressing a major clinical problem that negatively impacts patient care; (3) a track record of high-quality medical science published via peer-reviewed literature; (4) well-defined clinical cases for application; (5) quality evidence of benefits measured by various clinical, patient and health economic endpoints; (6) strong economic drivers; (7) user friendliness, including easy integration into clinical workflow, and (8) recognition of importance by patients and their endorsement for broader clinical use. Barriers raised by critics of the approach are given to balance the view. The value of MIPD will be decided ultimately by the extent to which it can improve cost-effective patient care.

Abstract:

ABSTRACT Developments in genetics, pharmacology, biomarker identification, imaging, and interventional biotechnology are enabling medicine to become increasingly more precise in “personalized” approaches to assessing and treating individual patients. Here we describe current scientific and technological developments in precision medicine and elucidate the dual-use risks of employing these tools and capabilities to exert disruptive influence upon human health, economics, social structure, military capabilities, and global dimensions of power. We advocate continued enterprise toward more completely addressing nuances in the ethical systems and approaches that can—and should—be implemented (and communicated) to more effectively inform policy to guide and govern the biosecurity and use of current and emerging bioscience and technology on the rapidly shifting global stage.

Abstract:

Abstract This article compares two episodes of technology transfer in the 1890s: the movement of bright tobacco production technology to south-central Africa with the spread of the crop to eastern North Carolina and South Carolina. It finds similarities in the people who introduced the crop, but significant differences in the methods used to produce it. This is troubling because the type is defined by the cultivation and especially the curing techniques used to produce it; it is also often described in the historical literature as "Virginia tobacco," even when grown elsewhere. The technological differences are the product of different environments, which include not only the climate but also many elements of the technological system beyond immediate human control: the availability and organization of labor, differences in market structures and marketing institutions, and the government incentives provided to buyers. Therefore, this essay takes as its subject the paradox inherent in the official classification of tobacco types regulated by the USDA and argues that varietal types represent a form of market regulation disguised as botanical taxonomy.
