In this letter, we present the first characterization for the achievable Degrees-of-Freedom (DoF) by Blind Interference Alignment (BIA) using staggered antenna switching in the K-user Gaussian Interference Channel. In such scheme, each transmitter is equipped with one conventional antenna and each receiver is equipped with one reconfigurable (multi-mode) antenna. Assuming that the channel is kn...

Concern over the impending retirement of several top-level managers led a county agency to engage in efforts aimed at more efficient succession management. Administrators developed plans to prevent the loss of invaluable knowledge and wisdom accompanying retirement of experienced agency leaders. The agency's Director of Finance (DoF) was one of the first key figures projected to retire, and a s...

Interactively creating and editing 3D content requires the manipulation of many degrees of freedom (DoF). For instance, docking a virtual object involves 6 DoF (position and orientation). Multi-touch surfaces are good candidates as input devices for those interactions: they provide a direct manipulation where each finger contact on the table controls 2 DoF. This leads to a theoretical upper bou...

In this paper, degrees of freedom (DoF) is investigated for theM×N single input single output (SISO) X channel with alternating channel state information at the transmitters (CSIT). It is known that the sum DoF of 2-user SISO X channel with synergistic alternating CSIT is the same as the sum DoF of 2-user (M = N = 2) SISO X channel with perfect CSIT [8]. In this paper, such 2-user X channel sch...

Vision-based techniques used in automatic micromanipulation are limited by small depth of field (DOF) because of high magnification and big numerical aperture of optical system. This paper proposed a new adaptive DOF image system which can adaptively adjust DOF during micromanipulation while maintaining high resolution of the images. The proposed system uses a spatial light modulator instead of...

Dof proteins are a family of transcription factors specific to the plant kingdom that contain a particular class of zinc finger DNA binding domain. Members of this family are involved in the regulation of genes related to a plethora of metabolic processes including stress or hormone response, seed and endosperm development, flowering, carbohydrate metabolism, and cell or tissue specificity. Dof...

The depth-of-field (DOF) measured through psychophysical methods seems to depend on the target's characteristics. We use objective and subjective methods to determine the DOF of the eye for different pupil diameters and wavelengths in three subjects. Variation of image quality with focus is evaluated with a double-pass technique. Objective DOF is defined as the dioptric range for which the imag...

To explore an issue of a human-like motion, we have constructed a human-like biped robot called WABIAN-RII (WAseda BIped humANoid robot-Revised II) that has a total of fortythree mechanical degrees of freedom (DOF); two six DOF legs, two ten DOF arms, a four DOF neck, four DOF in the eyes and a torso with a three DOF waist. For human-robot symbiosis, the biped humanoid robot is required to have...
