Synchronized single electron emission from dynamical quantum dots
, 2010 We study synchronized quantized charge pumping through several dynamical quantum dots (QDs) driven by a single time modulated gate signal. We show that the main obstacle for synchronization being the lack of uniformity can be overcome by operating the ...

Design Optimization of Lifting Mechanisms
IOP Conference Series: Materials Science and Engineering, 2019 The design of the lifting device (mobile crane vs tower crane) has big influence on construction efficiency and the whole building process. That is why we made this design optimization of lifting mechanisms for many types of building site. Basic algorithm of this methodology was made with respect to structure of the area, time and technology ...
