Xamarin as a tool for mobile development
Xamarin as a tool for mobile development was chosen as a topic for the thesis work because of its fast pace of growth. This technology was founded in May 2011 and now counts more 1.25 million developers who have already proven its worth. With help of this technology mobile development process will come to the new qualitative level where crappy software wonβt exist anymore.
The main goals for this project were to show Xamarinβs power with creating cross-platform mobile application and to prove its portability concept by making research that is proven by created prototype for Android and Windows Phone.
As a conclusion it is clearly stated that Xamarin has huge power for code sharing between mobile platforms. The project that has been created during thesis work fully proves main concepts
Using Corbino disk sample geometry to separate quasiparticle and vortex motion contributions to the mixed state dissipation of YBCO
A method, using a Corbino disk sample geometry, is described and applied to
study of resistive tails of sintered . When the transport current passes
radially from the rim of the disk sample to its center, the two component
potential drop signal is detected below , which is due to (i)
quasiparticles and (ii) vortex-core-motion related contribution . When the contact pairs for are placed radially, and are found to follow the markedly distinctive functional dependences,
providing a unique possibility to deconvolute the relative strengths of both
contributions. The results obtained suggest that the mixed state dissipation of
high- superconductors is strongly influenced by the quasiparticle
excitations.Comment: PDF fil
Electrical and thermal transport properties in high T_c superconductors : effects of a magnetic field
Experimental studies of the electric and heat currents in the normal,
superconducting and mixed states of high T superconductors (HTcS) lead to
characterization, complementary to data obtained from equilibrium property
based techniques. A magnetic field superimposed on the superconducting sample
generates {\it magneto-transport phenomena}, from which an excess electrical
resistivity, an excess thermoelectric power, the Hall or the Nernst effect.
Different behavioral effects allow one to distinguish various dissipation
mechanisms, like quasi particle scattering, vortex motion dissipation and
superconductivity fluctuations, in particular when the Corbino geometry is
used. Moreover bulk measurements of the thermal conductivity and the
electrothermal conductivity in a magnetic field give us sure indications of the
order parameter symmetry. The location of the mixed state phase transition
lines in the technological phase diagram of HTcS are briefly pointed out
through precise measurements performed over broad temperature and magnetic
field ranges. The results are mainly reviewed with the aim of defining further
investigation lines.Comment: 9 pages, no figures; to appear in Physica
Probing the field-induced variation of the chemical potential in Bi(2)Sr(2)CaCu(2)O(y) via the magneto-thermopower measurements
Approximating the shape of the measured in
magneto-thermopower (TEP) by asymmetric linear triangle of the
form with positive and defined below and above , we observe that . In order to account for this asymmetry, we
explicitly introduce the field-dependent chemical potential of holes
into the Ginzburg-Landau theory and calculate both an average and fluctuation contributions to the total
magneto-TEP . As a result, we find a rather simple relationship
between the field-induced variation of the chemical potential in this material
and the above-mentioned magneto-TEP data around , viz. .Comment: REVTEX (epsf), 4 pages, 2 PS figures; to be published in JET
Curvature effects on surface electron states in ballistic nanostructures
The curvature effect on the electronic states of a deformed cylindrical
conducting surface of variable diameter is theoretically investigated. The
quantum confinement of electrons normal to the curved surface results in an
effective potential energy that affects the electronic structures of the system
at low energies. This suggests the possibility that ballistic transport of
electrons in low-dimensional nanostructures can be controlled by inducing a
local geometric deformation.Comment: 11 pages, 3 figure
Estimation of the charge carrier localization length from Gaussian fluctuations in the magneto-thermopower of La_{0.6}Y_{0.1}Ca_{0.3}MnO_3
The magneto-thermoelectric power (TEP) of perovskite type
manganise oxide is found to exhibit a sharp peak
at some temperature . By approximating the true shape of the
measured magneto-TEP in the vicinity of by a linear triangle of the
form , we observe that . We adopt the electron localization scenario and
introduce a Ginzburg-Landau (GL) type theory which incorporates the two
concurrent phase transitions, viz., the paramagnetic-ferromagnetic transition
at the Curie point and the "metal-insulator" (M-I) transition at
. The latter is characterized by the divergence of the field-dependent
charge carrier localization length at some characteristic field
. Calculating the average and fluctuation contributions to the total
magnetization and the transport entropy related magneto-TEP
within the GL theory, we obtain a simple relationship between and the
above two critical temperatures ( and ). The observed slope
ratio is found to be governed by the competition between
the electron-spin exchange and the induced magnetic energy . The
comparison of our data with the model predictions produce ,
, , , and for the estimates of
the Curie temperature, the exchange coupling constant, the critical
magnetization, the localization length, and the free-to-localized carrier
number density ratio, respectively.Comment: 6 pages (REVTEX), 2 PS figures (epsf.sty); submitted to Phys.Rev.

Π΄ΠΈΡΡΠΈΠΏΠ»ΠΈΠ½.For today, along with the topical problem of adverse demographic forecast, and in connection with the prospect of the increase of retirement age, the issue of healthy lifestyle is becoming increasingly important.Thanks to the state policy, there is currently cross-sectoral interaction implemented for the purposes of the control and prevention of non-communicable diseases in order to create the necessary conditions for the populationβs healthy lifestyle.But despite the active policy of the state, many Russians, including students, do not have sufficient motivation to lead a healthy lifestyle.One of the components of the population strategy for non-communicable diseases prevention is the development of motivation to healthy lifestyle among students during their years at educational institutions. The specifics of medical universities are that the students trained there are the people to implement the population strategy of the future, including by providing a role model of themselves.The subject of our study is the level of knowledge on the healthy lifestyle concept. In our research, which was based on students, military students and medical residents of Military Medical Academy named after S.M. Kirov, we analyzed the formation of the concept of healthy lifestyle among students and the motivation to such lifestyle.In order to study the level of knowledge on the formation of motivation for a healthy lifestyle, a sample sociological survey of students on a specially designed questionnaire was conducted.As a result of processing the data of the survey, we were able to find out that most of the respondents have a low level of self-preservation culture and considers their lifestyle is not healthy enough, and would like to change it. Taking into account this desire of our respondents, we assume that it is possible to activate motivation to a healthy lifestyle within some disciplines
