Since the richness of computational verb rules, CVCNs are of many kinds.

In this paper, we use T-neighborhood, in which we just need to consider the center cell and three neighbor cells directly upon it. In T-neighborhood we observed many dynamic transmitting patterns and some special patterns that seem to be unchangeable and static of 2D CVCNs.","PeriodicalId":408223,"journal":{"name":"Anti-counterfeiting, Security, and Identification","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122571210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The context includes the description of small signal analysis and circuit design flow. The DT-SDM2 buck converter was designed and fabricated with a standard TSMC 0.35μm 3.3V CMOS process. The operating frequency of the proposed DT-SDM2 ranges from 1 to 5MHz. Compared to traditional pulse width modulator (PWM), using DT-SDM2 to control has greater noise suppressing ability. The measurement results show that the DT-SDM2 controlled converter suppresses the switching tones by 60dB at the switching frequency of 1MHz, and suppresses the switching tones by 30dB at the switching frequency of 5MHz.","PeriodicalId":408223,"journal":{"name":"Anti-counterfeiting, Security, and Identification","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127507339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The RFID Tags can be read by a Reader at a limited distance, and it can also be repetitively employed for data Identification. Once the data of Tags is read, RFID has its data to be transmitted and processed in different ways such as add, modify or delete at the host computer. The unlimited access characteristic of Reader to Tags to lead RFID has the capacities of potential security and privacy. The privacy of the consumer might be violated owing to the problems of lacking security in RFID Reader. Therefore, developing better security systems and protecting user privacy have become a research topic for RFID technology. This study presents a novel RFID structure to refrain various attacks from intruders. In the proposed method, the parameter values ai, bi and EPC [1] [2] are hidden by the random code r and n to avoid the ID of EPC leaking out to achieve privacy protection. The introduced method for the RFID system was with functions such as keeping data integrity and authentication, protecting of personal privacy, and retraining of data security from illegal intruder.","PeriodicalId":408223,"journal":{"name":"Anti-counterfeiting, Security, and Identification","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127121531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By utilizing a common topology, namely quasi z-source converter, the proposed PFC converter can well eliminate voltage spike on switches without dissipative components usage. As a result, low voltage rating Mosfets with low on-resistance Rds(on) can be used to achieve high efficiency. In addition, Continuous Conduction Mode (CCM) operation associated with the variable duty control scheme to regulate the output voltage is also applied to get high PF, low harmonic components in the line current. In this study, the principle of operation, circuit analysis, and control method of the proposed PFC converter are provided. Additionally, the design consideration are given and also verified by a laboratory prototype with 180 to 240 V AC input, 380 V/1 kW output, and 50 kHz switching frequency. Consequently, this topology is well suitable for high power, wide input voltage range applications where a unity PF, low THD, and high efficiency are required.","PeriodicalId":408223,"journal":{"name":"Anti-counterfeiting, Security, and Identification","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133214783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
