INFLUENCE OF ERRORS IN DETERMINATION OF TRACING SLOPE ON THE ACCURACY OF GEODETIC BASE FOR ROUTE

The purpose of this article is to study and develop a methodological approach tosolving the problem of accuracy of the geodetic base of the route. For this purpose, the followingtasks are set: mathematical substantiation the dependence of the line length on the ratio of the traceslope and the guide slope; description of the function of optimal use of the guiding slope at highspeed; determination of the impact of errors in the course of the geodetic justification on the routelength. Starting from the determined point and further to the right, artificial development of the lineis required. Because when a trace is planed using level curves, this point can be reached sooner orlater, and in some cases, this point can not be reached not at all, the line length designed accordingto the plan will be slightly different than in the case of tracing with usage the exact data. Thus, theobtained results indicate the following. If the error positions during a high-speed segment are suchthat the ordnance datum of the passage is less than the truth, the route length will be less than thetrue and vice versa. This trivial result indicates that the location of geodetic support points ondifferent sides of the pass is not recommended. It is established that due to the accumulation of errorsin the transmission of coordinates in the working substantiation networks, the conditions of the linedesign and the amount of operating costs change. It is mathematically substantiated that the linelength depends on the depth of the excavation on the pass and the height of the embankment at thepoint, and also on the difference of ordnance datum at these points. The difference between the traceslope and the guiding slope has an inversely proportional effect. In addition, the function of optimaluse of the guide slope at a high-speed segment has the form of a broken line according to its fracturesthe need for artificial development of the route can be established. The influence of errors in the course of the working justification is manifested in the discrepancy between the true and projectedroute length. If this error is not taken into account, it will lead to significant overspending duringbuilding a longer line than necessary. Further development of the problem of increasing the accuracyof tracing and reducing the impact of errors is planned in the direction of creating methods of digitalmodelling and automated programs.

Impact of colchicine on leaf morphology and stomatics of Kalanchoe tubiflora (Harv.) Raym.-Hamet (Crassulaceae)

The demand of medicinal plants for consumption is greatly increasing worldwide. The conventional breeding programs are generally dependent on the environment prone to biotic and abiotic stresses. These added to the low content of secondary metabolites at harvest, bring the need for artificial development of polyploid individuals as an alternative to increase productivity. Consequently, the present study evaluated the effect of different colchicine concentrations and exposure time, on Kalanchoe tubiflora leaf morphology and stomata. Initially, K. tubiflora seedlings were harvested and submitted to colchicine concentrations of 0, 0.025, 0.05 and 0.1 % and at two exposure times (24 and 48 hours). Subsequently, morphological measurements such as plant height, leaf width, leaves number, leaf length, leaf thickness and leaf volume every 15 days were made for 16 weeks after planting. Then, the stomata were characterized, taking into account the width, length, stomatal index and the number of chloroplasts per stoma. A significant increase in leaf morphology was found in colchicine treatments of 0.025 % at 48 h and 0.1 % at 24 h. A significant increase in stomatal morphology with the treatment of 0.025 % at 24 h was also recorded. This shows that the correct application of colchicine in term of quantity and time could produce greater growth in a short period and increase the biomass of K. tubiflora medicinal plant.

The Transhumanist conception of body: a critical analysis from a complex systems perspective

What is the conception of the human body underlying the Transhumanismproject? This question guides the present analysis undertaken from a philosophicalinterdisciplinary perspective. Inspired by Le Breton (2008) and Morin’s (2014)hypotheses about the complexity of the human body, we criticize mechanisticconception of the living body underlying the Transhumanism project. Implications ofthe Transhumanism project for personal identity are proposed based on hypotheses ofcomplex systems theory as a starting point for critical reflection on a possible gloomyfuture envisioned by the unnatural/artificial development of the transhuman body.

Repairing ASR output by Artificial Development and Ontology based Learning

General purpose automatic speech recognition (gpASR) systems such as Google, Watson, etc. sometimes output inaccurate sentences when used in a domain specific scenario as it may not have had enough training samples for that particular domain and context. Further, the accent of the speaker and the environmental conditions in which the speaker speaks a sentence may influence the speech engine to recognize certain words inaccurately. Many approaches to improve the accuracy of ASR output exist. However, in the context of a domain and the environment in which a speaker speaks the sentences, gpASR output needs a lot of improvement in order to provide effective speech interfaces to domain-specific systems. In this paper, we demonstrate a method that combines bio-inspired artifi- cial development (ArtDev) with machine learning (ML) approaches to repair the output of a gpASR. Our method factors in the environment to tailor the repair process.
