Drought is one of the major environmental stresses that adversely affect crop growth and productivity worldwide. For evaluation of drought stress on grain yield, yield components and drought tolerance indices, 20 genotype of rapeseed (Brassica napus L.) was studied in an experiment based on a randomized complete blocks design with three replications in two different conditions (stress and non-s...

anxiety disorders are the most common reasons for referring to specialized clinics. if the response to stress changed, anxiety can be greatly controlled. the most obvious effect of stress occurs on circulatory system especially through sweating. the electrical conductivity of skin or in other words galvanic skin response (gsr) which is dependent on stress level is used; beside this parameter pe...

Continuous stress monitoring may help users better understand their stress patterns and provide physicians with more reliable data for interventions. Previously, studies on mental stress detection were limited to a laboratory environment where participants generally rested in a sedentary position. However, it is impractical to exclude the effects of physical activity while developing a pervasiv...

In recent years, remarkable results have been achieved in the early detection of weeds, plant diseases and insect pests in crops. These achievements are related both to the development of non-invasive, high resolution optical sensors and data analysis methods that are able to cope with the resolution, size and complexity of the signals from these sensors. Especially hyperspectral cameras are ca...

high processing loads, need for complicated and frequent updating, and high false alarm are some of the challenges in designing anomaly detection and misuse detection systems. we propose a new network-based intrusion detection system (ids) that resolves such shortcomings. our scheme fuses anomaly detection and misuse detection systems, which has not been utilized so far in existing systems. in ...

AIMS We hypothesized that real-time color encoding of contrast-enhanced images would allow objective detection of stress-induced wall motion abnormalities (WMA). METHODS We studied 117 patients with poorly visualized endocardium undergoing dobutamine stress tests. Color-encoded images (Philips, color kinesis) were obtained at rest and peak stress in four standard views during i.v. infusion of...

Stress level detection is important for human error prevention and health care services. Speech based stress level detection is the most effective as speech data can be obtained in nonintrusive and inexpensive ways. In this paper, we explore the features that use Double-Layered Subband (DLS) filter for detecting stress level from speech. Spectral Centroid Frequency (SCF) and Spectral Centroid A...
