Исследование алгоритмов фильтрации при обработке зашумленных сигналов
В настоящей работе приводятся результаты исследований по доступным измерительным каналам. Исследование проводилось с позиции подавления высокочастотных случайных помех. Проведённое сравнение результатов подавления высокочастотных случайных помех, а также вычислений, выполненных с использованием БИХ-фильтров, КИХ-фильтров, фильтров на основе взвешенных оконных функций, а также фильтров на базе дискретного и непрерывного вейвлет-преобразования, свидетельствует о возможности выбора оптимальных видов частот. могут быть получены с учётом допустимого уровня достоверности и точности полученных результатов.This paper presents the results of research through available measurement channels. The study was conducted from the position of suppression of high-frequency random interferences. The carried out comparison of the results of suppression of high-frequency random interferences, as well as the calculations made with the use of BIH-filters, BIH-filters, filters based on weighted window functions, as well as filters based on discrete and continuous wavelet transforms, indicates the possibility of choosing the optimal types of frequencies
Прогнозирование временных рядов на основе штрафного P-сплайна
В работе исследуется возможность применения штрафного P-сплайна в задаче прогнозирования измерительной информации. Созданы компактные и экономичные формы вычисления сплайна в реальном времени и произведена настройка и оптимизация параметров.The possibility of applying the penalty P-spline in the problem of measuring information forecasting is investigated in this paper. Compact and economical forms of spline calculation in real time have been created, and parameters have been tuned and optimized

Executive Functions in Chronic Mesial Temporal Lobe Epilepsy
There is no consensus as to whether mesial temporal lobe epilepsy (MTLE) leads to executive function deficits. In this study, we adopted an extensive neuropsychological test battery and assessed different executive functions in chronic, unilateral MTLE. Performance of MTLE patients was compared with that of healthy peers and with normative data. Several MTLE patients had scores below cut-off or below the 10th percentile of normative data. Scores of the whole patient group were overall in the average range of normative data. Relative to controls, MTLE patients performed poorly in tests of working memory, cognitive flexibility, categorical verbal fluency, set-shifting, categorization, and planning. These findings raise an important methodological issue as they suggest that executive function deficits in chronic MTLE may be individually variable and that their assessment should include different tests. Deficits in chronic MTLE are not limited to temporal lobe functions, such as memory, but may extend to extra temporal cognitive domains, such as executive functions
Midbrain–hindbrain malformations in patients with malformations of cortical development and epilepsy: A series of 220 patients
SummaryMidbrain–hindbrain malformations (MHM) may coexist with malformations of cortical development (MCD). This study represents a first attempt to investigate the spectrum of MHM in a large series of patients with MCD and epilepsy. We aimed to explore specific associations between MCD and MHM and to compare two groups of patients: MCD with MHM (wMHM) and MCD without MHM (w/oMHM) with regard to clinical and imaging features.Two hundred and twenty patients (116 women/104 men, median age 28 years, interquartile range 20–44 years at the time of assessment) with MCD and epilepsy were identified at the Departments of Neurology and Pediatrics, Innsbruck Medical University, Austria. All underwent high-resolution MRIs (1.5-T) between 01.01.2002 and 31.12.2011. Midbrain–hindbrain structures were visually assessed by three independent raters.MHM were seen in 17% (38/220) of patients. The rate of patients wMHM and w/oMHM differed significantly (p=0.004) in three categories of MCD (category I – to abnormal neuronal proliferation; category II – to abnormal neuronal migration; and category III – due to abnormal neuronal late migration/organization): MCD due to abnormal neuronal migration (31%) and organization (23%) were more commonly associated with MHM compared to those with MCD due to abnormal neuronal proliferation (9%). Extensive bilateral MCD were seen more often in patients wMHM compared to those w/oMHM (63% vs. 36%; p=0.004). In wMHM group compared to w/oMHM group there were higher rates of callosal dysgenesis (26% vs. 4%; p<0.001) and hippocampal abnormalities (52% vs. 27%; p<0.001). Patients wMHM were younger (median 25 years vs. 30 years; p=0.010) at the time of assessment and had seizure onset at an earlier age (median 5 years vs. 12 years; p=0.043) compared to those w/oMHM. Patients wMHM had higher rates of learning disability (71% vs. 38%; p<0.001), delayed developmental milestones (68% vs. 35%; p<0.001) and neurological deficits (66% vs. 47%; p=0.049) compared to those w/oMHM.The groups (wMHM and w/oMHM) did not differ in their response to antiepileptic treatment, seizure outcome, seizure types, EEG abnormalities and rate of status epilepticus. Presence of MHM in patients with MCD and epilepsy is associated with severe morphological and clinical phenotypes
Ordinary differential equations for the dynamic characteristics of heating boilers
The paper presents ordinary differential equations for the dynamic characteristics of a solid fuel boiler that can be combined into one-dimensional nonstationary mathematical model for simulating long-term dynamics of a solid fuel boiler. This model requires less computational time for a qualitative simulation of boiler's operation than known CFD-solutions. The long-term dynamic model presented can help to determine annual costs, to set up automatic control systems and to detect dangerous deviations in the project
