Flow patterns of shallow Pali Lake induced by the dominant winds
Budinski Ljubomir,Fabianula
Facta Universitatis Series : Architecture and Civil Engineering , 2012, DOI: 10.2298/fuace1201055b
Abstract: Studies of lake currents have highlighted that in case of stagnant waters winds are the dominant driving forces. This study is dealing with the influence of dominant winds on the flow pattern of Pali Lake. Action of steady winds of different directions has been tested on the lake by means of a two dimensional numerical model, while in addition to winds all other permanent factors like actual bathymetry, inflow and outflow as well the Coriolis force have been accounted for. The experiments have revealed that winds of different directions created corresponding characteristic flow patterns (in base plot), which were similar in cases of winds having opposite directions. However, in such cases the direction of flow was opposite. Moreover, the Pali Lake model produced the well known double-gyre flow pattern: in the coastal strip the direction of the current corresponded to the wind direction, while it was opposite in the domain of open water.

Considera es preliminares sobre produto turístico étnico
Cardozo, Poliana Fabíula
PASOS : Revista de Turismo y Patrimonio Cultural , 2006,
Abstract: The concept of ethnicity can refer to the idea of the flow and (re)construction of authoctonal or transmigreted culture. The resulting outputs of ethnical communities cultural (re)constructions have drown special attention of tourism, and have also emerged new possibilities through the form of the so called ethnical touristic products. Therefore, it`s necessary a comprehension of concept of ethnicity, ethnical tourism, tourist product, as well as their peculiarities. The aim of this essay is to lead to prelimi-nary considerations about these issues according to the tendencies of the tourism industry, encouraging a follow-up discussion
Cost Analysis of Inpatients in a Psychiatric Clinic of a University Hospital
Halis ULA,Zeliha TUNCA
N?ropsikiyatri Ar?ivi , 2010,
Abstract: Objective: Inpatient cost of psychiatric disorders in Turkey is unknown. The aim of this study is to calculate the annual cost of inpatient population in a Psychiatric clinic of a university hospital in Turkey.Methods: The authors analyzed the data of psychiatric patients treated in the inpatient psychiatric clinic of the Dokuz Eylül University Hospital between January 2007 and December 2007. Retrospective chart review was performed to obtain sociodemographic and clinical data. The average annual inpatient treatment cost was calculated by multiplying the mean number of hospitalization by the average inpatient expenditure, and comparisons were made among 3 different diagnostic groups: psychotic disorders, mood disorders and other psychiatric disorders. Results: 291 inpatients were included in the study. The mean age of the patients was 39.9±15 years, the mean number of hospitalization was 1.04±0.2, the mean duration of hospitalization was 34.02±19.38 days and 53% of the patients were female. The average inpatient treatment cost of an individual patient was 1340.45±989.98 Turkish Liras (1029.69 US Dollars), and the cost of inpatient hospitalization per day was 40.81±21.67 Turkish Liras (31.35 US Dollars). The total inpatient costs were higher in psychotic disorders and mood disorders than in other psychiatric disorders. Conclusion: The annual inpatient treatment cost of psychiatric patients in Turkey is found to be lower than those in developed countries. There is insufficient data on the cost of psychiatric disorders in our country, and such information is important for planning mental health policy. (Archives of Neuropsychiatry 2010; 47: 144-9)
A Physical Model of a Smart Magneto-Composite Material and the Methodology of Research of the Elastic Properties of Nano Magnetic Composite Materials
Igor Dimitrov,Ula? Din?
Physics , 2014,
Abstract: In this study, we show that any system consisting of magnetic dipoles forming ordered or disordered configurations can be simplified to a form mathematically equivalent to a system consisting of two magnetic dipoles. It is shown that the energy of all kinds of magnetic dipole systems can be written as $E=\frac{\beta}{\alpha^3}$, where $\alpha$ is the nearest distance between the dipoles and $\beta$ is a certain constant depending on the magnetic moments of dipoles and configuration. Using this fact we model any nano-magnetic composite material by a simple two-magnetic dipole system. Then we experimentaly and theoreticaly show that under certain conditions the elastic properties of the composite material can be changed using exernal magnetic field which leads to creation of smart composite materials.
New Photometric Study of A Southern Contact Binary System: HI Puppis
B. Ula,C. Ulusoy
Physics , 2014, DOI: 10.1016/j.newast.2014.02.009
Abstract: We present results of new photometric observations of the contact binary system \astrobj{HI Pup} as well as the radial velocity curve of the system. Time series multicolour photometry was obtained at the South African Astronomical Observatory (SAAO) using the 1-m Cassegrain Telescope. We applied a simultaneous solution to the $BVRI$ light and radial velocity curves in order to determine the physical parameters of the system. From an analysis of the new multicolour data, the physical parameters were found to be $M_1=1.22M_{\odot}$, $M_2=0.23M_{\odot}$, $R_1=1.44R_{\odot}$, $R_2=0.67R_{\odot}$, $L_1=3.3L_{\odot}$, $L_2=0.7L_{\odot}$. Our solution confirms that HI Pup has a typical A--type W UMa binary system characteristics.
Nonuniform Sparse Recovery with Subgaussian Matrices
Ula? Ayaz,Holger Rauhut
Mathematics , 2010,
Abstract: Compressive sensing predicts that sufficiently sparse vectors can be recovered from highly incomplete information. Efficient recovery methods such as $\ell_1$-minimization find the sparsest solution to certain systems of equations. Random matrices have become a popular choice for the measurement matrix. Indeed, near-optimal uniform recovery results have been shown for such matrices. In this note we focus on nonuniform recovery using Gaussian random matrices and $\ell_1$-minimization. We provide a condition on the number of samples in terms of the sparsity and the signal length which guarantees that a fixed sparse signal can be recovered with a random draw of the matrix using $\ell_1$-minimization. The constant 2 in the condition is optimal, and the proof is rather short compared to a similar result due to Donoho and Tanner.
