An RFID (Radio Frequency Identification) device consists of a small and inexpensive microchip attached to an antenna. The chip can be very small and some RFID tags are thin enough to be embedded in paper. RFID are heavily used to track items in production environments and to label items in supermarkets, Hospital, Factory, License plate, Cattle….They are usually thought of as an advanced barcode. However, in this project we argue about RFID license plate and using RFID tags for recognize vehicle from distance. Radio Frequency Identification (RFID) tags has many applications in modern automatic and intelligent identification systems. Vehicles outfitted by RFID tags as License Plates, can be... 

By increasing growth of the composite materials and achieving nano-materials and understanding the unique and specific properties, using materials for production with ideal specifications widely spread. So far nano-materials were used for strengthening materials and producing composite and then nano composites were produced.
Regarding to widespread use of polymer matrix composites, nano particles for reinforcement polymers were used. Thus desirable and unexpected properties were observed in polymer matrix nano composites.
In this project, due to the unique properties of carbon nano tubes such as high strength and modulus, low density, and high ratio of length to diameter. They are... 

Corruption is one of the environmental destructive factors, which has a long history among firms. Lots of research has been done regarding the impact of corruption at both the micro and macro levels. Some researchers believe that corruption can have severe negative impacts on the firms and even to the macro-economic level. However, others believe that corruption can act as a tool by which firms can do their stuff more effectively and efficiently. For combating corruption, governments have always taken action. In recent years, by virtue of technological advancements and ICT (information and communication technologies) tools, governments have employed them to reduce the level of corruption. In... 

Cancer is one of the most critical diseases in the last century. Numerous efforts have been conducted to treat cancer. According to the report of World Health Organization, one death of every six deaths is due to this disease. More than 100 cancer types have been identified. Among these types, CNS tumor is one of the most critical cancer types with high mortality (65.9%). Various methods have been applied to treat this disease, but still, treatment efficiency is low. In this thesis, the effect of ultrasound waves on drug delivery into CNS tumors was evaluated using both experimental and simulation devices. A syringe pump was used to inject the drug solution into tissue-mimicking gels (CED)....
