abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
BACKGROUND/AIMS Neuropsychiatric symptoms in Alzheimer's disease (AD) are highly prevalent. We sought to determine whether neuropsychiatric symptoms were related to global functional impairment at baseline and over a 3-year period in older normal control (NC), mild cognitive impairment (MCI) and mild AD dementia subjects. METHODS Eight hundred and twelve subjects (229 NC, 395 MCI, 188 AD) fro...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
the aim was to compare the predictive power for type 2 diabetes mellitus (t2dm) using dynamic change (difference) of metabolic syndrome (ms), difference of fasting plasma glucose (fpg), baseline ms and fpg in cohort study.overall, 3461 subjects were recruited from prevention of multiple metabolic disorders and ms in jiangsu of china study with 3.8 years follow-up. cox proportional-hazards regre...
Jacobson, MS., J. Lehel and L.M. Lesniak, @threshold and $-tolerance chain graphs, Discrete Applied Mathematics 44 (1993) 191-203. In this paper we introduce a class of graphs called $-threshold graphs which generalize threshold graphs. These graphs are studied for various functions I+? that include “max” and “min” as special cases. The graphs are then shown to fit into the more general setting...
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
استفاده از داده¬های ماهواره ثقل¬سنجی گریس که قادر است میدان جاذبه را به طور دائم اندازه¬گیری کند به منظور تعیین تغییرشکل¬های ناشی از زلزله، با پرتاب این ماهواره بسیار مورد توجه قرار گرفت. در این پایان¬نامه از حل مسئله معکوس توسط الگوریتم ژنتیک به منظور استخراج پارامترهای گسل برای زلزله 8.8 ریشتری مائول شیلی در 27 فوریه سال 2010 به کمک ضرائب ماهیانه میدان جاذبه مشاهدات ثقل¬سنجی ماهواره گریس و ...
There seems to be something in the air: democratic societies around the world have had a rough time recently. Some, such as Turkey, Hungary and Poland, appear to be moving towards what Hungary’s Prime Minister, Viktor Orban, calls an “illiberal democracy,” soft authoritarianism veiled in the trappings of traditional democracies. The United Kingdom votes to Brexit from the European Union, leadin...
OBJECTIVE To estimate mortality from diabetes mellitus (DM) for the period 2001-2011 in the Republic of Panama, by province/indigenous territory, and determine its relationship with biological and socioeconomic risk factors. METHODS Cases for the years 2001-2011 with DM listed as the principal cause of death were selected from Panama's National Mortality Registry. Crude and adjusted mortality...
