Method for segmenting e.g. radially inner surface, of tire of car to discover defects and non-uniformities, involves processing image to segment image into regions corresponding to regions of tires, which do or do not belong to groove
No full textNOVELTY - The method involves irradiating a portion of a surface (5a) of a tire (P) with electromagnetic radiation including wavelength in a visible spectrum. An image of the portion of the irradiated surface is acquired. The image is processed to segment the image into regions corresponding to regions of the tires, which do or do not belong to a groove, by calculating a statistical quantity associated with irradiation by the radiation for the regions of the image and determining whether the regions of the image do or do not belong to the groove according to a value of the statistical quantity.
USE - Method for segmenting a surface e.g. radially inner surface and radially outer surface, of a tire of a car to discover defects and non-uniformities.
ADVANTAGE - The method enables improving efficiency in terms of accuracy of inspection of the tire, thus enabling the requisite defects and parameters of the surface to be detected while reducing errors with greater precision and accuracy. The method enables improving lighting and providing pre-processing of the acquired images before the inspection can be conducted with the required degree of reliability.

Method for controlling the manufacturing of tyres for wheels of vehicles
No full textA method for controlling the manufacturing of tires for wheels of vehicles includes: extracting a cured tire from a curing station, in which the cured tire has accumulated heat during a curing process; and verifying the presence of possible defects or imperfections in that cured tire. The verification includes detecting first electromagnetic radiations representative of a heat emission from different portions of the cured tire while the cured tire frees the accumulated heat; providing at least one output signal representative of the first electromagnetic radiations detected to allow an analysis of the cured tire and to verify the presence of the possible defects or imperfections. A plant for the manufacturing of tires for wheels of vehicles is also described
HSCT for stiff person syndrome and myasthenia gravis
No full textRecent advances in neuroimmunology have shed light on the pathogenic mechanisms underlying rare neuroimmunologic conditions such as myasthenia gravis (MG) and stiff person syndrome (SPS). Despite the rarity of these conditions, their complex manifestations and potential for irreversible disability necessitate effective therapeutic strategies. This chapter reviews the current understanding of the safety and efficacy of hematopoietic stem cell transplantation (HSCT) in MG and SPS. Several case reports and retrospective studies have demonstrated promising outcomes following HSCT in refractory MG and SPS, with significant clinical improvement and even discontinuation of chronic immunomodulatory therapy in some cases. Furthermore, HSCT may offer insights into the underlying pathophysiologic mechanisms of these conditions, particularly the role of cellular immunity. Although more research is needed to fully understand the impact of HSCT on disease pathology and outcomes, current evidence suggests that HSCT could be a valuable therapeutic option for patients with refractory MG and SPS
Increasing Market Interconnection: an Analysis of the Italian Electricity Spot Market
No full textWe estimate the benefits (in terms of savings to end-users)resulting from an improved interconnectivity in the Italian electricity spot market. The market is currently divided into two geographic zones – North and South – with limited inter-zonal transmission capacity that often induces congestion, and hence potential inefficiency. By simulating a fully interconnected market, we predict that the total spot market expenditure would reduce substantially. Moreover, since savings do not increase linearly with the size of new transmission capacity, even a slight increment to transmission capacity is found to substantially reduce endusers' expenditures. Finally, our analysis shows that the (partly State owned) dominant firm in the market is not maximizing short-term profits
DSMC Aero-Thermo-Dynamic Analysis of a Sample-Return Capsule
No full textFuture exploration programs, promoted by the main world space agencies, deal with sample return missions to planets like Mars or to asteroids and comets. In this study, an aero-thermo-dynamic analysis of a possible Earth Return Capsule during the high energy, high altitude re-entry path from an exploration mission is presented. The altitude interval 70-120 km is considered, where the capsule experiences different flow fields. In fact, rarefaction ranges from the continuum low density regime to the near free molecular flow and, even though the free stream velocity has been considered constant (13 km/s) in the whole altitude interval, the Mach number changes from 44 to 32 and the Reynolds number, based on the capsule diameter, ranges from 4.92???104 to 9. The computations were carried out using two direct simulation Monte Carlo codes: the 2-D code DS2V to compute local quantities such as heat flux, thermal and aerodynamic loads at zero angle of attack and the 3-D code DS3V to compute global aerodynamic coefficients in the range of the angle of attack 0-60 deg.. The results verified that in this altitude interval the heat flux and the thermal load satisfy reasonably the requirements for the thermal protection system and that the capsule is longitudinally stable up to an angle of attack of about 40 deg.
