Physics of Stimulated Scattering
1985In Sect. 1.2.3 a brief account was given of the fundamentals of the process of stimulated light scattering. However, a quantitative approach to the problem of optical phase conjugation by stimulated scattering requires a detailed theory of stimulated scattering (SS). It is to this theory that Chap. 2 is devoted.

On the physics of cyclic steam stimulation
Energy, 2016Abstract Steam fracturing as done during cyclic steam stimulation is an effective thermal process for initiating recovery from viscous oil reservoirs such as oil sands reservoirs found in Alberta, Canada and Liaohe, China. A key component of these processes is the ability to inject high temperature steam into the formation to fracture it which in ...

Physical stimulation of newborn infants in the delivery room
Archives of Disease in Childhood - Fetal and Neonatal Edition, 2017Objective Neonatal resuscitation guidelines recommend that newborn infants are stimulated to assist with the establishment of regular respirations. The mode, site of application and frequency of stimulations are not stipulated in these guidelines.

Mobile Application to Stimulate Physical Activity in Schoolchildren
2016 12th International Conference on Intelligent Environments (IE), 2016We present the "e-Gibalec" system, which was designed to stimulate and motivate schoolchildren to be physically active and to assist physical education (PE) teachers and parents to track their progress. The system consists of a smartphone application which uses built-in sensors to monitor activities, and a web application for PE teachers and parents ...

Physics of effects of transcranial brain stimulation
2013The effects of transcranial stimulation are determined to a large extent by the spatial distribution and temporal variation of the electric field produced in the brain. In this chapter, we first describe some of the factors that affect the electric field in the brain generally, such as the effect of tissue heterogeneity and anisotropy, or focality ...

Physical Stimulation in Tissue-Engineering
2019The tissues in our body are complex three-dimensional structures, each with its own unique combination of cells and extracellular matrix. The activities of the resident cells are co-ordinated by signals that they receive from soluble factors and neighbouring cells, but also by physical cues provided by the composition, architecture and mechanical ...

Physical-Perceptual Correspondence for Dynamic Thermal Stimulation
IEEE Transactions on Haptics, 2017Thermal displays have been applied in various haptic applications, from material simulation to interpersonal communication; however, there is insufficient knowledge about the temporal processing in human thermal sense to provide a knowledge basis for thermal display design.

Effect of Physical Stimulation on Motor Inhibition in Children
Perceptual and Motor Skills, 1986The effect of physical stimulation on motor inhibition and cognitive performance of 70 third-grade children was examined. 46 subjects participated in a brief, but strenuous obstacle course. Their performance on two motor inhibition tasks, a short-term memory/attentional task, and a test assessing reflectivity was assessed before the stimulation ...
