Open Journal of Obstetrics and Gynecology (OJOG) , 2015, DOI: 10.4236/ojog.2015.55038
Abstract:

Background: Risk management is improving quality of health care services and creating a safer system of care. We determined the main maternal and fetal risks in five Hospitals (Tehran-Iran) to offer some practical strategies to decline obstetric adverse events and provide better pregnancy outcome. Methods: A descriptive, cross-sectional study was carried out in 5 Iranian hospitals (2011-2012).Twelve Obstetricians/perinatalogists and midwives from 5 hospitalswho were in charge of Maternity Units, were our assistants in these hospitals. We organized a secretariat including Obstetricians/perinatalogists and midwives. The principles of Obstetrics Risk Management were introduced to them in a 2 days’ workshop. Then the delegates from each hospital were asked to report the most common obstetrical complications of their hospitals. The main results were 24 complications. Then for sorting these risks we asked them to do scoring of the 24 complication with 1 - 10 grading in 4 aspects of probability of occurrence, possibility of prevention, priority of interventions and short term response to interventions. Post partum haemorrhage, labor management problems, and neonatal hypothermia got the highest scores in these regards, and then these 24 items were categorized in 2 groups of risk assessment and hospital management. Finally based on Risk Management Rules in Clinical Governance, the complications analysis was done with use of failure mode, effects analysis and practical strategies to decline obstetrical adverse events were suggested. Results: We understood all reported complications had common infrastructural problems: defects in Risk Assessment and Hospital Management Policies. We focused on basic infrastructural management in these 2 main subjects and in these two: our main problems were related to staff management and hospital management issues. Conclusion: Since managerial and staff dependent problems were our main problems, these two should be considered as our main priorities in risk management program.

Complex Tropical Currents, Extremality, and Approximations
Farhad Babaee
Mathematics , 2014,
Abstract: To a tropical $p$-cycle $V_{\mathbb{T}}$ in $\mathbb{R}^n$, we naturally associate a normal closed and $(p,p)$-dimensional current on $(\mathbb{C}^*)^n$ denoted by $\mathscr{T}_n^p(V_{\mathbb{T}})$. Such a "tropical current" $\mathscr{T}_n^p(V_{\mathbb{T}})$ will not be an integration current along any analytic set, since its support has the form ${\rm Log\,}^{-1}(V_{\mathbb{T}})\subset (\mathbb{C}^*)^n$, where ${\rm Log\,}$ is the coordinate-wise valuation with $\log(|.|)$. We remark that tropical currents can be used to deduce an intersection theory for effective tropical cycles. Furthermore, we provide sufficient (local) conditions on tropical $p$-cycles such that their associated tropical currents are "strongly extremal" in $\mathcal{D}'_{p,p}((\mathbb{C}^*)^n)$. In particular, if these conditions hold for the effective cycles, then the associated currents are extremal in the cone of strongly positive closed currents of bidimension $(p,p)$ on $(\mathbb{C}^*)^n$. Finally, we explain certain relations between approximation problems of tropical cycles by amoebas of algebraic cycles and approximations of the associated currents by positive multiples of integration currents along analytic cycles.
Modeling Breast Cancer Incidence Rates: A Comparison between the Components of Functional Time Series (FTS) Model Applied on Karachi (Pakistan) and US Data  [PDF]

Open Journal of Applied Sciences (OJAppS) , 2016, DOI: 10.4236/ojapps.2016.68052
Abstract: Several studies showed that the breast cancer incidence rates are higher in high-income (developed) countries, due to the link of breast cancer with several risk factors and the presence of systematic screening policies. Some of the authors suggest that lower breast cancer incidence rates in low-income (developing) countries probably reflect international variation in hormonal factors and accessibility to early detection facilities. Recent studies showed that the breast cancer increased rapidly among women in Pakistan (a developing country) and it became the first malignancy among females of Pakistan. Although, the incidence rates may contain important evidence for understanding and control of the disease; however in Pakistan, the breast cancer incidence data have never been available in the last five decades since independence; rather, only hospital-based data are available. In this study, we intend to apply Functional Time Series (FTS) models to the breast cancer incidence rates of United State (developed country), and to see the difference between various components (age and time) of Functional Time Series (FTS) models applied independently on the breast cancer incidence rates of Karachi (Pakistan) and US. Past studies have already suggested that the incidence of US breast cancer cases was expected to increase in the coming decades. A progressive increase in the number of new cases is already predetermined by the high birth rate that occurred during the middle part of the century, and it will lead to nearly a doubling in the number of cases in about 4 decades. We also obtain 15 years predictions of breast cancer incidence rates in United States and compare them with the forecasts of incidence curves for Karachi. Development of methods for cancer incidence trend forecasting can provide a sound and accurate foundation for planning a comprehensive national strategy for optimal partitioning of research resources between the need for development of new treatments and the need for new research directed toward primary preventive measures.
Measuring Global Warming: Global and Hemisphere Mean Temperature Anomalies Predictions Using Sliced Functional Time Series (SFTS) Model  [PDF]
Farah Yasmeen
Open Journal of Applied Sciences (OJAppS) , 2019, DOI: 10.4236/ojapps.2019.95026
Abstract: In this study, the sliced functional time series (SFTS) model is applied to the Global, Northern and Southern temperature anomalies. We obtained the combined land-surface air and sea-surface water temperature from Goddard Institute for Space Studies (GISS), NASA. The data are available for Global mean, Northern Hemisphere mean and Southern Hemisphere means (monthly, quarterly and annual) since 1880 to present (updated through March 2019). We analyze the global surface temperature change, compare alternative analyses, and address the questions about the reality of global warming. We detected the outliers during the last century not only in global temperature series but also in northern and southern hemisphere series. The forecasts for the next twenty years are obtained using SFTS models. These forecasts are compared with ARIMA, Random Walk with drift and Exponential Smoothing State Space (ETS) models. The comparison is made on the basis of root mean square error (RMSE), mean absolute percentage error (MAPE) and the length of prediction intervals.
Explanation of Capacitive Performance of the Plasma in Damavand Tokamak  [PDF]
Shervin Goudarzi, Fatemeh Dadgarnejad, Hojat Babaee
Open Journal of Applied Sciences (OJAppS) , 2015, DOI: 10.4236/ojapps.2015.52004
Abstract: In this work capacity of tokamak plasma is calculated using modeling of tokamak configuration as toroidal and coaxial capacitor. This value is very important and plays an important role in time- varying regimes in tokamak. For exact simulation of plasma behavior, this amount will be added to circuit equations and transport codes. Since capacitive properties of tokamak cause production of a radial electric field, it deserves our special attention.

Open Journal of Applied Sciences (OJAppS) , 2015, DOI: 10.4236/ojapps.2015.55022
Abstract: Concerning the increasing global energy demand, the current paper considers nuclear energy as a solution. Within this context, the 2011 disaster in Fukushima Nuclear Power Plant and, particularly, the technical disorders in boiling water reactors are explained. The deficiency of safety technique in boiling water reactors is explained. The deficiencies in safety procedure of this type of reactors manifested during 2011 earthquake and subsequent tsunami are explained. To complete the discussion, the newer technologies of reactors enabling them to act more safely during natural disasters are introduced. These investigations indicate that despite improvement in the fission reactor technologies, the danger embedded in them still remains. Therefore, the nuclear fusion using Deuterium-Tritium reaction is the best way forward for energy production in the future, and the best candidate of this type of reactors is Tokamak.

Siamak Babaee,Ruzbeh Babaee,Morteza Habibi Nesami
Studies in Literature and Language , 2012, DOI: 10.3968/j.sll.1923156320120403.2355
Abstract: The present study pursues the evolution of an organized system of play writing known as the modern and contemporary social drama. It is believed that this social drama has its roots in the condition of life in the nineteenth century and in a larger sense, it is the inevitable consequence of a long process which has begun with the Renaissance. In relation to this inquiry, the present study by focusing on Harold Pinter's The Homecoming (1965) attempts to clarify the social position of men and women in the modern drama. In this regard, the present paper points briefly to the social condition of life in the nineteenth century, and considers its inevitable effects on our time and then depicts the reflection of that condition on modern social drama. Key words: Social drama; Modernism; Nineteenth century; Social condition
Stephan’s Brave New World: A Deconstructive Reading on James Joyce’s A Portrait of the Artist as a Young Man
Ruzbeh Babaee,Iraj Montashery
Studies in Literature and Language , 2011, DOI: 10.3968/2172
Abstract: A Portrait of the Artist as a Young Man (1914) is considered to be one of the major examples of the genre bildungsroman (the novel of the artist). This study concerns the search of the protagonist, Stephen Dedalus, for identity and meaning, which encompass a time period from his infancy to his late adolescence. In quest of identity and meaning, Stephen breaks from two totalities- nationalism and Catholic Church- that rule over his life. The present study reads the novel within a deconstructive perspective. Stephen like Nietzsche wants to talk about “the death of god” to pave the way for his exploration of meaning and identity. He tends to rebel and go beyond what Lyotard calls “the grand narrative”. Key words: Deconstruction; Metanarrative; Nationalism; Catholic Church; Simulation
A Nonlinear ILC Schemes for Nonlinear Dynamic SystemsTo Improve Convergence Speed
Hossein Babaee,Alireza Khosravi
International Journal of Computer Science Issues , 2012,
Abstract: In this paper we study nonlinear Iterative Learning Control (ILC) schemes for nonlinear dynamic systems. The methods are proposed in this paper such as Newton-Type and Secant-Type, for improve the convergence speed in nonlinear ILC schemes systems. In nonlinear Iterative Learning Control methods convergence speed is faster than the linear ILC schemes systems. The system taken into consideration is the one phase control of the switched reluctance motor (SRM) and simulation result show that the convergence speed of the Newton-Type ILC schemes is the fastest and the Secant-Type is faster than the linear-type but slower than the Newton-Type. On the other hand nonlinear ILC schemes require more prior knowledge about the system.
A minimization principle for the description of time-dependent modes associated with transient instabilities
Hessam Babaee,Themistoklis Sapsis
Physics , 2015,
Abstract: We introduce a minimization formulation for the determination of a finite-dimensional, time-dependent, orthonormal basis that captures directions of the phase space associated with transient instabilities. While these instabilities have finite lifetime they can play a crucial role by either altering the system dynamics through the activation of other instabilities, or by creating sudden nonlinear energy transfers that lead to extreme responses. However, their essentially transient character makes their description a particularly challenging task. We develop a minimization framework that focuses on the optimal approximation of the system dynamics in the neighborhood of the system state. This minimization formulation results in differential equations that evolve a time-dependent basis so that it optimally approximates the most unstable directions. We demonstrate the capability of the method for two families of problems: i) linear systems including the advection-diffusion operator in a strongly non-normal regime as well as the Orr-Sommerfeld/Squire operator, and ii) nonlinear problems including a low-dimensional system with transient instabilities and the vertical jet in crossflow. We demonstrate that the time-dependent subspace captures the strongly transient non-normal energy growth (in the short time regime), while for longer times the modes capture the expected asymptotic behavior.
