Polycarbonate (PC) is a widely used engineering thermoplastic. Also, bead foaming technology method to produce high-performance, low-density foams with complex geometries. In this work, expanded polycarbonate (EPC) microcellullar structure and low density have been produced for the first time using autoclave technique. The effect of processing parameters, such as saturation temperature time, on...

The National Electronic Product Code (EPC) Network Demonstrator Project (NDP) was the first large scale consumer goods track and trace investigation in the world using full EPC protocol system for applying RFID technology in supply chains. The NDP demonstrated the methods of sharing information securely using EPC Network, providing authentication to interacting parties, and enhancing the abilit...

Radio frequency identification (RFID) is an automatic data capture technology that has great potential to improve business. However, RFID projects have significant up-front costs: buying tags and readers, and installing them in business locations. Until now, a physical deployment was required to properly test RFID software and its integration with existing systems. This paper describes EPC Virt...

Over the last years several European patents were opposed for protecting technology violating the morality requirement under Article 53(a) EPC. Attempts have been made by the Appeal Boards of the European Patent Office (EPO), as well as by amendments introduced into the Implementing Regulations of the European Patent Convention (EPC), to address this sensitive patentability requirement more pre...

Radio frequency identification (RFID), an identified object technology, utilizes air interface to deliver information required for object identification. The applicable technical information of RFID is convenient to manage and operate, and is widely promoted by the large-scale chain industry. Additionally, electronic product code (EPC) network technology enables immediate, automatic identificat...

Election incidents – where the elections system fails voters – are of increasing concern with the dramatic rise in the use of computerized electronic voting machines that store vote records in computer memory. The Election Protection Coalition (EPC) used a web-based election incident recording and reporting tool called the Election Incident Reporting System (EIRS) developed by the Verified Voti...

Introduction Computers these days are no longer just placed on desktops in the form of stationary machines, they are also embedded into everyday objects. The seamless integration of computing capabilities within physical objects is the foundation for an Internet of Things, which interlinks the physical world of goods and items with the virtual world of services and data bases. The most prominen...

The dynamic strain aging (DSA) behavior was investigated in GH4169 alloy during tensile deforming with electric-pulse current (EPC) at 750 °C. results show that DSA is restrained the when deformed 40 Hz-EPC. size of γ″ phase inner grains increases obviously and δ facilitated to precipitate on grain boundary applied EPC, due promotion effect EPC diffusion segregation atoms. Transmission electron...

Introduction The adoption of RFID technology [1] for products identification is experiencing an increasing diffusion in the logistics pipeline, where RFID systems are expected to have a major impact on the efficiency of the whole supply chain. Commonly quoted benefits of RFID encompass increased processes automation, accuracy, and labour efficiency [2]-[3]. There are several reasons for this di...
