The 5G wireless communication system supports varied applications, making the uplink/downlink traffic asymmetry more and more serious. Dynamic time division duplex (TDD) technique has become a key technology of 5G networks due to its flexibility to support asymmetric services. In this paper, we study dynamic TDD sub-frame reconfiguration algorithm based on shifting. Firstly, we define cell shif...

An estimated 260 million indigenous peoples live in Asia. Most of them inhabit forested uplands where a large number of them practice shifting cultivation, which is also called as swidden cultivation or rotational farming. For them, shifting cultivation is not merely a technique of farming; it is their ways of life. Government policies and laws have attempted to limit or outright ban shifting c...

A direct measurement protocol allows reconstructing specific elements of the density matrix a quantum state without using tomography. However, protocols to date are primarily based on weak or strong measurements with an ancillary pointer, which interacts investigated system extract information about specified elements. Here, we present scheme phase-shifting operations do not need pointers. In t...

<sec> Phase shifting profilometry (PSP) is an effective technique to reconstruct the three-dimensional shape of object. In general, PSP needs three or more fringe patterns with phase-shifting accurately known extract phase distribution objects. Therefore, scene and test objects should remain stationary during capturing patterns. However, shifts may be unknown in actual measurement system,...

The perfectly synchronized round model provides the powerful abstraction of crash-stop failures with atomic message delivery. This abstraction makes distributed programming very easy. We present an implementation of this abstraction in a distributed system with general message omissions. Protocols devised using our abstraction (i.e., in the perfectly synchronized round model) are automatically ...

The technique of generating sinusoidal fringe patterns by defocusing squared binary structured ones has numerous merits for high-speed three-dimensional (3D) shape measurement. However, it is challenging for this method to realize a multifrequency phase-shifting (MFPS) algorithm because it is difficult to simultaneously generate high-quality sinusoidal fringe patterns with different periods. Th...
