Context. Nonlinear nonstationary processes are observed today in various fields of studies: economy, finances, ecology, demographyetc. Very often special approaches are required for model development and forecasts estimation for the processes mentioned.Th... see more

We aimed to evaluate the psychological, emotional and relational burden of nurses who provide assistance to patients affected by Amyotrophic Lateral Sclerosis (ALS). A survey was conducted by administering a questionnaire, the “Health Professions Stress a... see more

Many segmentation problems have been addressed using probabilistic modeling. These methods tend to estimate the region membership probabilities for each pixel of the image. The segmentation results depend strongly on the initialization of these regions an... see more

The main objective of online anomaly detection is to identify abnormal/unusual behavior such as network intrusions, malware infections, over utilized system resources due to design defects etc from real time data stream. Terrabytes of performance data gen... see more

Development of superior genotypes with high adaptability to different environments is considered as one of the most important goals in safflower breeding programs. In this study, ten parametric and six non-parametric measures along with the additive main ... see more

This research paper presents statistical comparisons between two methods that are commonly used to estimate option implied Risk-Neutral Densities (RND). These are: 1) mixture of lognormals (MXL); and, 2) volatility function technique (VFT). The former is ... see more

This paper deals with multiobjective nonlinear programming problems, with parameters in the objective functions, without differentiability assumptions on the considered functions. The stability notions like the solvability set and stability sets of the fi... see more

Optical parametric oscillator (OPO) tunable in the range 970-1460 nm has been developed using bet barium borate (BBO) crystal as the gain medium and second harmonic of Nd:YAG laser as pump source. Two sets of resonators were used to cover the range; first... see more

This paper establishes an upper estimate for the Frechet normal cone to the graph of the nonlinearly perturbed polyhedral normal cone mappings in finite dimensional spaces. Under a positive linear independence assumption on the normal vectors of... see more
