At present,the traffic engineering and automation have developed,and the vehicle license plate recognition technology need get a corresponding improvement also.In case of identifying a car license picture,the principle of automatic license plate recognition is illustrated in this paper,and the processing is described in detail which includes the pre-processing,the edge extraction,the license plate location,the character segmentation,the character recognition.The program implementing recognition is edited by Matlab.The example result shows that the recognition method is feasible,and it can be put into practice.

This guidance provides general standards which should be used for to register with the Center for Veterinary Medicine (CVM or the Center) Electronic Submission System (ESS) to submit information in electronic format using the FDA Electronic Submissions Gateway (ESG). FDA's guidance documents, including this guidance, does not establish legally enforceable responsibilities. Instead, guidance describing the Agency's current thinking on a topic and should be viewed only as recommendations, unless specific regulatory or statutory requirements are cited. The use of the word should in Agency guidances means that something is suggested or recommended, but not required.

A burst-mode PDM-16QAM digital receiver, implemented offline in MATLAB, is demonstrated. We test the receiver digital signal processing (DSP) algorithms with experimental data from a prototype optical switching node, consisting of a PLZT-based optical switching matrix with optical packet add-drop capabilities. By using wideband optical packets, a raw capacity of 10.24-Tbit/(s·port) (20 Gbaud 16-QAM, 64 wavelength channels, and 2-Polarizations) is achieved below the forward error correction (FEC) limit of 3×10~(-3).

Stennis Space Center was interested in using smart sensors to monitor components on test stands and avert equipment failures. Partnering with St. Paul, Minnesota-based Lion Precision through a Cooperative Agreement, the team developed a smart sensor and the associated communication protocols. The same sensor is now commercially available for manufacturing.

In 2012, the Office of the National Coordinator for Health Information Technology (ONC) conducted a nationally representative telephone survey of 2,050 adult individuals, in both English and Spanish. The survey focused on their privacy and security attitudes, in particular when their health information is stored or transmitted electronically via EHRs and HIE. This data brief reports individuals perceptions about the measures put in place by providers to protect EHRs, and its association with support for EHRs, HIE and patient-provider communication.

The paper proposes a method to reduce operational force in a bilateral teleoperation system that realizes simultaneity property under communication delay. A bilateral control that realizes simultaneity property is previously proposed, which is achieved by buffering the force information. It focused on the fact that force information from the master motor is the pure information that actuates the motor, therefore, timing of the force information input is corrected. However, the control system requires large force when operator tries to operate the system. The paper clears the reason and the problem is solved by utilizing the delayed position information of the own system. The proposed control system is designed to mix present and buffered position information to reduce the operational force. The delayed information can easily affect the stability problem, therefore, phase compensator is used. The validity of the proposed method is confirmed by experiments.

As part of the effort to build the Fast Affordable Science and Technology Satellite (FASTSAT), Marshall Space Flight Center developed a low-cost telemetry unit which is used to facilitate communication between a satellite and its receiving station. Huntsville, Alabama-based Orbital Telemetry Inc. has licensed the NASA technology and is offering to install the cost-cutting units on commercial satellites.

The Federal Communications Commission (FCC) has established buildout requirements-which require a licensee to build the necessary infrastructure and put the assigned spectrum to use within a set amount of time-for most wireless services, including cellular and personal communication services. FCC tailors the buildout requirements it sets for a wireless service based on the physical characteristics of the relevant spectrum and comments of stakeholders, among other factors. Therefore, buildout requirements vary across wireless services. For example, a buildout requirement can set the percentage of a license's population or geographic area that must be covered by service or can describe the required level of service in narrative terms rather than numeric benchmarks. Buildout requirements also vary by how much time a licensee has to meet a requirement and whether it has to meet one requirement or multiple requirements in stages. FCC's enforcement process for wireless-service licenses with buildout requirements primarily relies on information provided by licensees, and FCC followed its process for the five wireless services GAO reviewed. Specifically, FCC requires licensees to self-certify that they have met buildout requirements. If a licensee does not do so, FCC automatically terminates the license. Some stakeholders GAO interviewed said that self-certification is an effective way for FCC to enforce buildout requirements because it is public and transparent. GAO examined FCC license data for five wireless services and found that buildout requirements were met for 75 percent of those licenses, and FCC generally terminated those that did not. As part of enforcement, FCC also grants or dismisses licensees' requests to extend the deadline for meeting a requirement. FCC may grant an extension if the licensee shows that it cannot meet a deadline due to causes beyond its control, like a lack of available equipment. For the five wireless services examined, GAO found that extensions were requested for 9 percent of licenses, and FCC granted 74 percent of these requests. FCC officials said that the Commission seeks to be aggressive but pragmatic when enforcing buildout requirements, including being flexible on deadlines when needed. Some licensees and industry associations GAO interviewed said that extensions can provide needed flexibility when unexpected problems occur. Some concerns were raised, however, that granting extensions can undermine buildout requirements by creating an impression that they will not be strictly enforced.

This paper describes application of a complex band-pass (BP) Δ∑ DA modulator to I-Q signal generation for communication IC testing. We examine the characteristics of the complex BP Δ∑ DA modulator and confirm the effectiveness of Data-Weighted Averaging(DWA) algorithm for real and complex multi-bit multi-BP Δ∑ DA converters. We also present theoretical analysis and simulation results.
