Recently, radio frequency identification (RFID) systems have gained popularity in manufacturing units, inventory, and logistics, as they represent an inexpensive and reliable solution for automatic identification. Moreover, RFID transponders are expected to become a key element in the ubiquitous computing scenario. Tags will likely be used to collect(More)
Typically, commercially available standard-cell libraries consist of a large set of items, including cells optimized with respect to speed, area or power consumption. A large number of cells makes the synthesis process and the library maintenance quite demanding. By using a reduced set of properly-selected cells, such efforts can be reduced, without(More)
A novel microwave method has been applied to the hydrothermal extraction of essential oil from plants. An insulated microwave coaxial antenna was introduced inside a 1000 ml glass flask containing dry Laurus nobilis L. leaves and tap water. Microwave power up to 800 W at 2450 MHz was emitted in continuous wave regime (CW) or in pulsed regime (PR) at 8 kW(More)
The Italian national transplantation network has set up programs for liver, heart, and lung transplantation in urgent conditions. The aim of this study was to analyze the capability of these programs to meeting needs and their quality. In period between 2008 and 2011, the total number of urgent transplant requests was analyzed by organ, reason, and outcome,(More)
Recently RFID (radio-frequency identification) systems have gained popularity in manufacturing units, inventory, logistics, as they represent an inexpensive and reliable solution for automatic identification. RFID tags are expected to become a key element in the future ubiquitous computing scenario. Low-cost passive (i.e. featuring no batteries) tags are(More)
Cheap passive radio frequency identification (RFID) tags operating in ultra high frequency (UHF) bands are fostering innovation in several field such as building access control, goods tracking, supply chains management and automatic product checkout. RFID transponders can also be coupled to tiny sensors, enabling non invasive monitoring of environmental and(More)
This article gives an overview of a novel, experimentally simple and versatile method of activation of chemical processes with microwaves without resorting to an oven. It is based on the use of a microwave antenna, namely an open-end coaxial dipole applicator immersed in an ordinary reaction vessel. Accounts of the apparatus at 2450 MHz and of the(More)
