The millimeter-wave phased array in the user equipment (UE) for 5G communication is studied in this letter. In particular, the body effect on the phased array in the UE at 15 GHz is investigated with the 3-D measurement data, and its impact on some key parameters for phased array in the UE, such as the total scan pattern, the coverage efficiency, and the probability of detection, are analyzed.
Objective: The purpose of this study was to compare postoperative rehabilitation with structured physiotherapy to the standard approach in patients with cervical radiculopathy (CR) in a prospective randomized study at 6 months follow-up based on measures of neck-related physical function, self-efficacy, and coping strategies. Methods: Patients with persistent CR and scheduled for surgery (N = 202)
This paper addresses Test Application Time (TAT) reduction for core-based 3D Stacked ICs (SICs). Applying traditional test scheduling methods used for non-stacked chip testing where the same test schedule is applied both at wafer test and at final test to SICs, leads to unnecessarily high TAT. This is because the final test of 3D-SICs includes the testing of all the stacked chips. A key challenge
The usual practice to measure the zero sequence voltage on the D-side of a transformer is to use three voltage transformers (VT), each of them connected between each phase and earth on the primary side and broken-delta connected on the secondary side. In this paper a method is presented for the estimation of the zero sequence voltage on the D-side of a Dy transformer by the use of only one VT conn
Forestry has been one of the major industries in the Swedish economy since the middle of the nineteenth century. During the second part of the twentieth century the industry went through powerful technological changes. Traditional handicraft methods were replaced by modern high technology. As for the forestry VET this meant a strong expansion during the 1950s and 1960s followed by integration into
