Approaches to Active Tourism in the Urals and in Perm Krai
Located in the south of Ural, Perm Krai, apart from mineral resources and well-developed industry, can boast vast areas that lend themselves to active and qualified tourism, with the quality of an amateur sport. The development of these forms of tourism often requires large expenditure needed for adjusting the space to various types of activity. It also requires a correlation between a given character of the space and the preferred form of tourism, which often leads to environmental conflicts between the development of tourism and nature protection. The article presents the most important elements of the tourism potential in Perm Krai, as well as the sports tourism development perspectives in the context of real and potential environmental conflicts
Mathematical Modeling of a Solar Arrays Deploying Process at Ground Tests
This paper focuses on the creating of a mathematical model of a solar array deploying process during ground tests. Lagrange equation was used to obtain the math model. The distinctive feature of this mathematical model is the possibility of taking into account the gravity compensation system influence on the construction in the deploying process and the aerodynamic resistance during ground tests
Frontiers of QCD with Precision nPDFs
Searches for new physics will increasingly depend on identifying deviations
from precision Standard Model (SM) predictions. Quantum Chromodynamics (QCD)
will necessarily play a central role in this endeavor as it provides the
framework for the parton model. However, as we move to higher orders and into
extreme kinematic regions, we begin to see the full complexities of the QCD
theory. Recent theoretical developments improve our ability to analyze both
proton and nuclear PDFs across the full kinematic range. These developments are
incorporated into the new nCTEQ15 PDFs, and we review these developments with
respect to future measurements, and identify areas where additional effort is
required.Comment: Published in the "6th International conference on Physics

The informational mind and the information integration theory of consciousness
According to Aleksander and Morton’s informational mind hypothesis, conscious minds are state structures that are created through iconic learning. Distributed representations of colors, edges, objects, etc. are linked with proprioceptive and motor information to generate the awareness of an out-there world. The uniqueness and indivisibility of these iconically learnt states reflect the uniqueness and indivisibility of the world. This article summarizes the key claims of the informational mind hypothesis and considers them in relation to Tononi’s information integration theory of consciousness. Some suggestions are made about how the informational mind hypothesis could be experimentally tested, and its significance for work on machine consciousness is considered
Study of Queuing Theory M/M/M and Optimization Services Teller at Retail Banking
The research was conducted at retail banking in order to determine significant differences the average number of customers and the average waiting time in the system and the queue of Split Decision System. As well as the significance and probability of no customers in the system utilization teller services from Split Decision Systems at retail banking. The elected locations for sample were Bank Mandiri Ahmad Yani Branch and Bank Central Asia Sudirman Branch in Pekanbaru. Data was collected with a probability sampling technique by random sampling, so the data were taken at random in the queuing system is running at 10:00 to 12:00 and 13:00 to 15:00 hours on weekdays based on observations. Observation is by observing and measuring the amount of the average customer arrival (x) and the average number of customers served (μ) in a period of time (hours) in the queuing system. The results of the test sample t test showed that there were significant differences in the average number of customers and the utility both in the system and in the queue of Split Decision System. This is indicated the t value is smaller than the table t, and no significant difference on average waiting time and the probability of no customers in both the system and the queue of Split Decision System. This is indicated the t value greater t table is obtained, and for the number of teller enabled to obtain the optimal cost is 7 teller's for a transaction 25 million in the Mandiri Bank.
Research of Wheat Drying in a Microwave and Combined Filter-microwave Dryer
The aim of the conducted study is to determine kinetics of the complex effect of microwave energy supply and filter drying of the process of water release from the wheat layer. There is offered a combination of MW and filter drying. A special feature of this combination must be its more effectiveness and high speed of water elimination from surface layers of wet seeds and, as a result, the productivity increase of the drying way, decrease of specific energy consumption.There was determined the influence of the specific load of the material, radiator power on processes of microwave and filter-microwave drying of wheat seeds. There were compared microwave, filter-microwave and convective drying of seeds by parameters of specific energy consumption, drying speed.The specific energy consumption at microwave drying of seeds was 4 MJ/kg, at filter-microwave drying 3.8 MJ/kg that is lower than existent convective dryers. The speed of microwave drying changes from 0,5 to 3 %/min, filter-microwave – from 0.3 to 0.7 %/min. The speed is at the level of standard convective dryers.The conducted studies allow to recommend a new combined way of FMW drying of seeds with low energy consumption.Revealed features of heating and drying are possible to be used at developing industrial dryers.The base of experimental data is possible to be used for optimizing and determining effective conditions of MW and FMW drying
Quantum affine Gelfand-Tsetlin bases and quantum toroidal algebra via K-theory of affine Laumon spaces
Laumon moduli spaces are certain smooth closures of the moduli spaces of maps
from the projective line to the flag variety of GL_n. We construct the action
of the quantum loop algebra U_v(Lsl_n) in the equivariant K-theory of Laumon
spaces by certain natural correspondences. Also we construct the action of the
quantum toroidal algebra U^{tor}_v(Lsl}_n) in the equivariant K-theory of the
affine version of Laumon spaces. We write down explicit formulae for this
action in the affine Gelfand-Tsetlin base, corresponding to the fixed point
base in the localized equivariant K-theory.Comment: v2: multiple typos fixed, proofs of Theorems 4.13 and 4.19 expanded,
