One of the most important problem in target tracking is Line Of Sight (LOS) rate estimation for using from PN (proportional navigation) guidance law. This paper deals on estimation of position and LOS rates of target with respect to the pursuer from available noisy RF seeker and tracker measurements. Due to many important for exact estimation on tracking problems must target position and Line O...

Beautiful darks in bright light. That's another way of saying that reflections from the display surface are under control. Perhaps we will see advertisements like this in the future. However, such a description is vague unless the reflection properties are clearly indicated. If we were to only state the familiar diffuse and specular reflection properties, would the specifications be adequate? N...

the purpose of this study was to examine how four teachers used the seven processes of videotape analysis to develop an analytic approach and reflective thinking towards their teaching. the study was organized within video clubs and was used to describe the interactions among four teachers about their experiences at a language institute. data were gathered through videotaped recordings of lesso...

Three-dimensional molecular dynamics simulations of hyperthermal copper atom impacts with copper surfaces have been used to investigate the effects of incident atom energy upon atomic reflection and resputtering during physical vapor deposition. No reflection or resputtering has been observed for incident energies below 10 eV. However, as the incident energy was increased to 20 eV and above, th...

Do we think enough about what we are doing as information literacy (IL) practitioners? The relationship between reflection and IL development is well documented in academic and professional literature, particularly in the context of teaching librarians using reflective activities to enable learners to think critically about their IL abilities. Parallel literature from education and other fields...

 In view of the fact that pre-service teachers’ critical reflection through evaluating teaching activity of their peers is an important part of practicum activity, the current study aimed to analyze the recall and reflection journals written by pre-service teachers to identify and evaluate the discoursal features of their journals. To this end, a total of 272 recall and reflection journals writ...
