Tail-biting in growing-finishing pigs with intact tails: evaluating group size and litter origin
Tail-biting is a persistent welfare and production challenge in swine systems, resulting in pain, stress, impaired growth, and economic losses. Despite extensive research, the behavior remains difficult to predict and prevent. The overarching objective of this dissertation was to investigate social …

Underwater acoustic communications and adaptive signal processing
… acoustic wireless communications. One is a new tail-biting circular MAP decoder for full tail-biting convolution (FTBC) codes for very short data blocks intended for Internet of Underwater Things (IoUT). The proposed algorithm was evaluated by ocean experiments and computer simulations on both …

Welfare issues in Italian heavy pig production
… studies investigated the feasibility of avoiding tail docking under different husbandry conditions (Trial A and Trial B), besides the benefit of providing straw enrichment by racks (Trial A). Surgical tail docking within the first week of life is the routine solution in several EU countries to …

Overloaded Array Processing with Spatially Reduced Search Joint Detection
… iterative joint detection with a (possibly) tail-biting and time"-varying trellis. The algorithm is sub-optimal but is demonstrated to well approximate the optimum receiver in modest signal to interference ratios. SRSJD is shown to demodulate over 2M zero excess bandwidth synchronous QPSK …

The effects of periodic environmental enrichment at different life stages on the welfare and production of growing pigs
… evaluated after weaning and when moving to GF. Tail bites and body lesions were assessed throughout GF. A subsample of pigs was transported to the abattoir and carcass characteristics were analyzed. Statistical analysis of Early and Late life data was done using mixed linear models. Growth was …
