1. Early mobilization after total hip or knee arthroplasty: a substudy of the POWER.2 study

Abstract Background Early mobilization after surgery is a cornerstone of the Enhanced Recovery After Surgery (ERAS) programs in total hip arthroplasty (THA) or total knee arthroplasty (TKA). Our goal was to determine the time to mobilization after this surgery and the factors associated with early mobilization. Methods This was a predefined substudy of the

9. MIMO-PLC Communications in an Experimental Medium Voltage Network: Measurement and Analysis

Abstract This paper presents measurements at a mock-up medium voltage network to verify the feasibility of Broadband Power Line Communication (BPLC). We use the data extracted within the frequency range 2 − 30 MHz to characterize a MIMO PLC network using different phase combinations, defining the best and worst use case scenarios. The empirical data shows
