OPC Unified Architecture (OPC UA) is the new standard of the OPC Foundation providing interoperability in process automation and beyond. By defining abstract services, OPC UA provides a service-oriented architecture (SOA) for industrial applications – from factory floor devices to enterprise applications. OPC UA integrates the different flavors of the former OPC specifications into a unified ad...

The present study aims to investigated Iranian L2 speaker`s knowledge of the overt pronounconstraint (OPC) in English. It also aims to examine L2 learners understanding of UniversalGrammar (Chomsky 1981, 1986, 2000, 2001) and if it is common to all languages. Specifically,this study takes a new look at the L2 acquisition of knowledge of the overt pronoun constraint(Montalbetti 1984) by Persian ...

The OPC UA technology complements the traditional OPC industrial standard by adding important characteristics such as platform independence, scalability, high availability, and Internet capability. Many automation component vendors already offer OPC UA clients or servers for their PLCs, process control systems, field devices, or operator panels. An efficient and cost-effective way to develop co...

The runtime of model-based optical proximity correction (OPC) tools has grown unacceptably with each successive technology generation, and has emerged as one of the major bottlenecks for turnaround time (TAT) of IC data preparation and manufacturing. The cell-based OPC approach improves runtime by performing OPC once per cell definition as opposed to once per cell instantiation in the layout. H...

We tested whether contamination of avierated by random amplified polymorphic DNA an blood by the parasite Haemoproteus could cause (RAPD). DNA was extracted from blood taken from the amplification of false positive genetic markers genfive Rock Doves (Columba Zivia) infected with Huemoproteus, and one uninfected control individual. A drug treatment was administered to clear the infection, 1 Rece...

The submitting of OPC (OLE for Process Control) has promoted the progress of the data collection in process control and industrial automation, and formulated the industry standard for the process real-time data exchange. Aiming at the key problem of ensuring the use of application program as OPC client to link multi-remote OPC server and real-time collect process data in control system, OPC tec...

items, structured items, strings, integers, sequences of bytes, XML data, OPC binary and so forth. Each data item is accompanied by a Data Type Description that defines the structure of the item and a Dictionary described each of the Data Types. The dictionary contains all information that the OPC client needs to be recognized the complex data item it is receiving. The OPC complex data specific...

Many implementations of the OPC-UA are increasingly available. Until now, use of technologies like the OPC-UA was limited to embedded systems with a sufficient amount of memory resources. OPC-UA offers a scalable feature set that could be tailored according to application demands. We believe that a key to successfully enable Internet of Things for the industrial automation applications lies in ...

BACKGROUND Human papillomavirus-associated oropharyngeal carcinoma (HPV-OPC) is clinicopathologically distinct entity from the HPV-unassociated one (nHPV-OPC). This study aimed to determine the relationship between histological subtypes of OPC and HPV status for Japanese cases and to identify histological structures of HPV-OPC. METHODS 66 OPC cases were categorized into conventional squamous ...

OBJECTIVE To review recent literature on human papillomavirus-related (HPV-positive) oropharyngeal squamous cell carcinoma (OPC) and focus on implications of recurrent and metastatic disease. METHODS Primary articles from 1990 to 2016 indexed in MEDLINE (1) pertaining to the epidemiology of HPV-positive OPC and (2) providing clinical insight into recurrent and metastatic OPC. RESULTS The in...
