Особенности проектирования многокоординатных пьезоактюаторов
Description of batch piezo actuators, formulas for calculation of absolute and relative deformations in first and second approximation are brought. Example of modification of machine methods for more accurate calculation of anisotropic solids and more specifically of piezo ceramics is shown. Triaxial piezo actuator solution is suggested and it’s work scheme is described. Disadvantages of batch piezo actuators and methods of their removal are shown
Heat pipes application in nanotechnological equipment is considered on examples of probe movement manipulators. Approaches to improvements of manipulators for effective heat extraction from operating area are shown.
Base concepts of finite elements method are given. Machine experiment with piezoceramic actuator is made. Machine experiment results are compared with results of theoretical researches in current area.
The International Conference founded by the prominent scientist Professor V.P.Sigorsky will be held on April 15-18, 2014 at National Technical University of Ukraine "Kyiv Polytechnic Institute".
The wellknown professionals as well as post-graduate students from Ukraine, Russia, Armenia, Germany, South Korea, Mexico, USA traditionally participate in the conference.
We propose a method for high-sensitivity subwavelength spectromicroscopy based on the usage of a spaser (plasmonic nanolaser) in the form of a scanning probe microscope tip. The high spatial resolution is defined by plasmon localization at the tip, as is the case for apertureless scanning near-field optical microscopy. In contrast to the latter method, we suggest using radiationless plasmon pumping with quantum dots instead of irradiation with an external laser beam. Due to absorption at the transition frequencies of neighboring nano-objects (molecules or clusters), dips appear in the plasmon generation spectrum. The highest sensitivity is achieved near the generation threshold.
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
