Two integrable generalizations of WKI and FL equations: Positive and negative flows, and conservation laws

With the aid of Lenard recursion equations, an integrable hierarchy of nonlinear evolution equations associated with a 2 × 2 matrix spectral problem is proposed, in which the first nontrivial member in the positive flows can be reduced to a new generalization of the Wadati–Konno–Ichikawa(WKI) equation. Further, a new generalization of the Fokas–Lenells(FL) equation is derived from the negative flows. Resorting to these two Lax pairs and Riccati-type equations, the infinite conservation laws of these two corresponding equations are obtained.

Low Intensity Microwave Fields and Radiation and Their Interaction with the Human Body

Sources of low-intensity microwave signals formation,which affect the metabolism processes when they interact with human body,are considered in the article.It’s noticed that increasing intensity level of the technogenic signals in environment significantly exceeds natural electromagnetic fields and radiation(EMR).The peculiarities of the registration and measurement of low-intensity signals parameters of the microwave range are considered.The processes of the interaction of the microwave signals and human organism are analyzed.Formation mechanisms of the positive and negative microwave flows of the electromagnetic radiation are revealed.Particularly,possible formation mechanism of the microwave EMR fluxes of implants in the human body.The results of the experimental study of the EMR signals levels of the objects contacting with human body,partly materials for bone defects replacement and soft tissues regeneration so as materials for physiotherapy,are given.The use of the term“electromagnetic compatibility”for materials which contacting the human body,is proposed.The expediency of its use is proven.Microwave properties of materials for clothes,minerals and building materials,which can affect the human body and environment,have been also studied.

A Study on the Methods for Estimating the Distribution of Pedestrians in an Underground Mall by Use of Watch Cameras

This paper shows the method of estimating spatiotemporal distribution of pedestrians by using watch cameras. We estimate the distribution without tracking technology, with pedestrian＇s privacy protected and in Umeda underground mall. Lately spatiotemporal distribution of pedestrians has being increasingly important in the field of urban planning, disaster prevention planning, marketing and so on. Although many researchers have tried to capture the information of location as dealing with some sensors, some problems still remain, such as the investment of sensors, the restriction of the number of people who has the device they are able to capture. From such background, we develop an original labelling algorithm and estimate the spatiotemporal distribution of pedestrians and the information of the passing time and the direction of pedestrians from sequential images of a watch camera.
