Le prime trascrizioni del palinsesto di Gaio e il presunto «mistero» delle schede veronesi (BCapVr, Cod. DCCCIX)
2014
This paper addresses the question of the origin of the partial transcription of Gaius’ palimpsest still preserved in the Capitular Library of Verona (BCapVr, Cod. DCCCIX) and allows to solve the pretended «mystery» about its presence in this library. A comparison with the fair copy (Reinschrift) of the transcription belonging to the Berlin State Library – Prussian Cultural Heritage (SBB-PK, Ms. lat. fol. 308, K. 1, Konv. 1) shows that the Cod. DCCCIX of the Capitular Library can not be regarded as a forgotten copy or a gift. Similarly, the idea that the manuscript was the first fair copy of the transcription works is not plausible. Anyway, a neglected information provided by one of the Prus…
Asymptotic observer of the link states of flexible joint robots with motor-side sensing
2015
This paper proposes an approach for observing the link states, i.e. angular position and velocity, of the robotic joints with elasticities, when only the motor-side sensing is available. By separating the state-dependent nonlinearities of the rigid manipulator dynamics a linear sub-model of the elastic joint robot is obtained in an observable state-space form. The standard asymptotic Luenberger state observer is then designed for the given motor position signal which is measured by encoder and rectified from the nonlinear contribution. The configurable poles of observer allow shaping the estimated states dynamics to be fast enough in relation to the actual resonant joint behavior. Therefore…
Observation and Processing of Instantaneous Frequency Variations During Bearing Tests
2020
Laboratory experiments have been performed on medium sized roller bearings with two levels of artificial damage. Recordings of long time series from accelerometers at a wide range of different radial loads and rotation speeds has been performed. Probably due to non-perfect performance of the control systems for the rotational speed or frequency, significant fluctuations were observed at all rotation speeds. The highest relative variation was observed at the lowest rotational speeds. These variations were recorded using a rotary encoder, which allows order tracking of the vibration signal. In real life condition monitoring, tachometers or rotary encoders are not always present, this can be d…

Hierarchical Parallelization of an H.264/AVC Video Encoder
2006
Last generation video encoding standards increase computing demands in order to reach the limits on compression efficiency. This is particularly the case of H.264/AVC specification that is gaining interest in industry. We are interested in applying parallel processing to H.264 encoders in order to fulfill the computation requirements imposed by stressing applications like video on demand, videoconference, live broadcast, etc. Given a delivered video quality and bit rate, the main complexity parameters are image resolution, frame rate and latency. These parameters can still be pushed forward in such a way that special purpose hardware solutions are not available. Parallel processing based on…
Violenza sessuale via WhatsApp? L’estensione della nozione di atto sessuale in una sentenza della Cassazione
2021
La sentenza in epigrafe si segnala all’attenzione perché riconosce la configurabilità del reato di violenza sessuale nella condotta di colui che, nell’ambito di una conversazione via whatsapp, dopo avere inviato una foto erotica, riceva dall’altro, dietro minaccia di pubblicare su canali social la chat sessualmente esplicita, una foto con esposizione di una zona erogena (nella specie, il seno nudo). Secondo i giudici, lo scambio di foto e la chat, operati attraverso la nota applicazione informatica di messaggistica e nella specie intercorsi fra un soggetto adulto e una ragazza minorenne, costituiscono «atto sessuale»; in ragione dell’anzidetta minaccia, la condotta costrittiva a compiere l’…
Supporting Impact Analysis by Program Dependence Graph Based Forward Slicing
2007
Since software must evolve to meet the typically changing requirements, source code modifications can not be avoided. Impact analysis is one of the central and relatively demanding tasks of software maintenance. It is constantly needed while aiming at ensuring the correctness of the made modifications. Due to its importance and challenging nature automated support techniques are required. Theoretically, forward slicing is a very suitable technique for that purpose. Therefore, we have implemented a program dependence graph (PDG) based tool, called GRACE, for it. For example, due to the typical rewritings of Visual Basic programs there is a great need to support their impact analysis. However…
Quadratus Lumborum Block Reduces Postoperative Opioid Consumption and Decreases Persistent Postoperative Pain Severity in Patients Undergoing Both Op…
2021
Background: New regional techniques can improve pain management after nephrectomy. Methods: This study was a randomized controlled trial conducted at two teaching hospitals. Patients undergoing elective open and laparoscopic nephrectomy were eligible to participate in the trial. A total of 100 patients were divided into a quadratus lumborum block (QLB) group (50 patients) and a control (CON) group (50 patients). At the end of surgery, but while still under general anesthesia, unilateral QLB with ropivacaine was performed on the side of nephrectomy for patients in the QLB group. The main measured outcome of this study was oxycodone consumption via a patient-controlled anesthesia (PCA) pump d…

Perceptual uncertainty is a property of the cognitive system
2012
AbstractWe qualify Frost's proposals regarding letter-position coding in visual word recognition and the universal model of reading. First, we show that perceptual uncertainty regarding letter position is not tied to European languages – instead it is a general property of the cognitive system. Second, we argue that a universal model of reading should incorporate a developmental view of the reading process.
