Emotion, as a psychophysiological state, plays an important role in human communications and daily life. Emotion studies related to the physiological signals are recently the subject of many researches. In This study a hybrid feature based approach was proposed to examine affecti
Temporal Variation Measure Analysis: An Improved Second-Order Difference Plot
In this study, an improved second-order difference plot is proposed to analyze the variability of heart rate variability. Although variation physiological status cardiovascular system can be shown graphically by plot, descriptive ability existing indicators for insufficient. As a
A Classification System to Detect Congestive Heart Failure Using Second-Order Difference Plot of RR Intervals
A classification system to detect congestive heart failure (CHF) patients from normal (N) patients is described. The classification procedure uses the k-nearest neighbor algorithm and uses features from the second-order difference plot (SODP) obtained from Holter monitor cardiac

On a Rado Type Problem for Homogeneous Second Order Linear Recurrences
In this paper we introduce a Ramsey type function S(r; a, b, c) as the maximum s such that for any r-coloring of N there is a monochromatic sequence x1, x2, . . . , xs satisfying a homogeneous second order linear recurrence axi + bxi+1 + cxi+2 = 0, 1 6 i 6 s − 2. We investigate S
The Generation of Higher-order Linear Recurrences from Second-order Linear Recurrences
Along the lines of this theorem, Selmer [1] has shown how one can form a higher-order linear recurrence consisting of the term-wise products of two other linear recurrences. In particular, let {sn} be an m-order and {tn} be a p-order linear integral recurrence with the associated
Analysis Of PID Controller For Second Order System Using NI Labview
Many processes and systems work well only within a narrow range of physical parameters like temperature, humidity, pressure etc. Certain chemical reactions, biological processes, and even electronic circuits perform best within limited parameters ranges. So, these processes need
evaluation of development scenarios of the ecological connectivity in ahvaz city in order to improve of the ecosystem services and biodiversity stage
introduction ecosystem services are the benefits that human derives from the ecosystems. these are servicessuch as goods and products (e.g., fresh water, fuel), regulation of natural processes (e.g., climate, flooding, erosion), and nonmaterial benefits (e.g., recreation, aesthet
First-order and second-order visual processes in the perception of motion and tilt.
It has been known for many years that the mammalian visual system contains neurones which respond selectively to the orientation of contours in the image, and to the direction of their movement. Numerous perceptual studies have also found evidence for the existence of orientation
Second-order Monte Carlo uncertainty/variability analysis using correlated model parameters: Application to salmonid embryo survival risk assessment
This paper presents a Monte Carlo uncertainty/variability analysis applied to assessment of salmonid embryo survival affected by the deposition of fine sand in the spawning gravel riverbed. For the system being modeled, the uncertainty originates from the lack of perfect knowledg
