Data compression techniques applied to high resolution high frame rate video technology

An investigation is presented of video data compression applied to microgravity space experiments using High Resolution High Frame Rate Video Technology (HHVT). An extensive survey of methods of video data compression, described in the open literature, was conducted. The survey examines compression methods employing digital computing. The results of the survey are presented. They include a description of each method and assessment of image degradation and video data parameters. An assessment is made of present and near term future technology for implementation of video data compression in high speed imaging system. Results of the assessment are discussed and summarized. The results of a study of a baseline HHVT video system, and approaches for implementation of video data compression, are presented. Case studies of three microgravity experiments are presented and specific compression techniques and implementations are recommended

Analysis of an IEEE 802.11-based protocol for real-time applications in agriculture

La tesi descrive un sistema originale basato sullo standard IEEE 802.11 per il monitoraggio ed il controllo remoto in tempo reale di una macchina agricola attraverso dispositivi commerciali quali smartphones e tablet. Le prestazioni del sistema sono state attentamente caratterizzate, sia dal punto di vista teorico che da quello pratico, tramite numerose sessioni di misure sperimentali. Opportune soluzioni alle problematiche riscontrate sono proposte, evidenziando sostanziali miglioramentiopenEmbargo temporaneo per motivi di segretezza e/o di proprietà dei risultati e informazioni di enti esterni o aziende private che hanno partecipato alla realizzazione del lavoro di ricerca relativo alla tes
