A methodical and didactical complex "Sign Language" . ... ABSTRACT The process of communication of the deaf includes the wide use of the sign language. ... The aim of this work is to develop a tool that should facilitate process of sign language teaching and also give to the trainee a means for independent study of various normative variants of sign language - for example, Russian, English, International and so on. ... The process of dialogue of the deaf people includes wide use of sign languages. ...

Introduction The suggested invention relates to attitude control system of a spacecraft. ... Systems without interaction with ambient (Systems with jet engines) Here, for instance, we can put systems, which can generate torque because of jettisoning any particles or gas. ... The main element of the suggested attitude control system is an electrical motor, which main feature is absents of a stator. ... 3 Block diagram of an attitude control system on a jet engines base. ... It is a system with| | ...

... FEATURES OF OBTAINED IMAGES All images obtained by the TESIS have a number of artifacts, i.e., the dark current, flat field, blurring (related to the feature of input shutters and CCD matrices of the equipment), and frame damage caused by the entry of cosmic particles. In addition, poor accuracy of the spacecraft stabilization leads to the fact that separately taken images of the Sun have a ran dom displacement and rotation relative to the CCD matrix. ... Methods of image recording of the TESIS. ...

... Multiexposition 34 images Sun 1/1000 sec f/22 and 1 image background. ... It shows position of the Sun on the sky in the same time of a day during one year. Analemma - a trace of the annual movement of the Sun on the sky - is well known among experts of sun-dials and old Earth's globes as a diagram of change of seasons and an equation of time. ... Previously, the position of the Sun on the sky was calculated with computer as well as optimal moments of time for taking each of the exposures. ...
