According to the issues encountered by traditional web chart technologies, the paper, following the boom of HTML5, did a research into web mapping of vector nautical charts based on HTML5. The research mainly includes: 1) System architecture for the HTML5 based web chart application, in which HTML5, CSS and Javascript are used to build and style the client Web chart pages, and Node. Js is used to construct the server-side to provide both HTTP and Web Socket services, 2) Organization of vector chart data to obtain more efficiency of data network transmission and data procession, for which original S-57 charts are converted into Shape files and a Javascript framework is designed to read and parse the Shape files for the client, 3) Vector nautical charts display on Web page, for which a Javascript display framework and rendering functions for chart points, lines and areas symbols are designed based on HTML5 Canvas. An application of web chart based vessel tracking is tested further to verify the proposed methods. The results showed that HTML5 is suitable to develop web vector chart applications, although there are several problems waiting to be solved such as it can't comply with S-52 display standard completely.

Cloud messaging push notification services are key features of pervasive mobile applications where invocations occur asynchronously and it is important that the mobile users are notified in a timely fashion of the available services. This article summarizes Push technology evolution including key techniques, features and architectures. It presents four kinds of push notifications such as Microsoft Push Notification service, Google Cloud Messaging, Blackberry Push service, Apple Push Notification service. It also analyses these four push notification approaches. In addition, it proposes a CPTEM to evaluate and select the most appropriate push mechanisms.

The spatial panel data model is commonly used in practice. In order to explore the property of the parameter estimator for the spatial error panel data model with fixed effects, the quasi-maximum likelihood estimator for the model is provided in this paper. And two theorems on the asymptotic properties of the estimator are proposed and proved. For illustration, the associated simulation is employed to verify the effectiveness of the proposed strategies. Empirical results show that when the number of the spatial units is large and the number of the time series is finite, the estimator is consistent and asymptotically normal. In conclusion, it is an estimator with good performance.

We present a bionic auditory system for musical instrument recognition. This system is designed based on the physiological structures of the human auditory system that are essential to sound source recognition, such as the basilar membrane and inner hair cells in the cochlea of the inner ear, cochlear nucleus, and the auditory cortex. A large solo database consisting of 243 acoustic and synthetic solo tones over the full pitch ranges of seven different instruments (guitar, harp, horn, piano, saxophone, trumpet, and violin) is used to encompass different sound possibilities of each instrument. The gamma tone model, the Meddis model, and poster ventral cochlear nucleus (PVCN) model are constructed to imitate the basilar membrane, the inner hair cells, and the cochlear nucleus, respectively. By using 33%/67% splits between training and test data, a self-organizing mapping neural network (SOMNN) based on the function of auditory cortex is established to classify the instruments. The instruments are recognized with an overall success rate of over 75%. This bionic auditory system indicates high efficiency and high accuracy in musical instrument recognition.

In order to improve the overall throughput of processors, to increase thread-level parallelism (TLP) and instruction-level parallelism (ILP) intra and inter cores, and ensure the scalability of multi-core systems, can a novel mechanism chip multithreading with resource unit manager (RUM-CMT) be used, which is presented in this paper. By introducing the efficiency difference of resource utilization among threads, such as, the condition of dynamically resource allocation to CMT architecture and add an absorption barrier for all threads to make their reserved resources far away from hidden hunger. For verify the applicability of RUM-CMT, a 4 cores with 2 threads processor and a 4 cores with 4 threads processor are simulated based on GEMS & Simics simulator. And this limited study shows RUM-CMT can increase performance by 29.79%, and an improve success committed instructions per squash instructions by 31.15% and fairness attains 6.25% improvements over static partition on 4 cores with 4 threads processor. The 4 cores with 2 threads also attains passable enhance. So RUM-CMT can accurately and concise reallocate resource according to phase turning in the running of applications, improve resource utilization, mining the ILP and TLP in applications. In other words, RUM-CMT improves the controllability of threads, reduces invalid losses and improves system efficiency, and it is a suitable solution for multicore, multithreaded architecture.

Currently, the LXI data acquisition system often requires high speed, large capacity memory, but the internal storage resource of FPGA is not sufficient to meet the requirements. In order to solve above problems, a SDRAM controller is proposed in this paper, where the Multiple FIFO based on the on-chip resources of FPGA serves as the read and write cache to realize the multiple functional modules performing the read/write operation in LXI acquisition system by the design of priority algorithm and reasonable controlling the access of SDRAM from external device. At the same time, the SDRAM can still communicate at high frequency by the suitable time limitation. The simulation results show that the proposed SDRAM controller can not only realize reading and writing data, but also its operating frequency is able to meet the requirements of functional modules.

In this paper, an anti-phishing technique based on e-mail extraction and analysis is proposed. The technique approached with phishing email, the channel phishing attack transmits, distinguish phishing emails and extract the suspicious URL from the e-mail for further analysis. Upon arrival, a protected list is built according to those third parties which are the most vulnerable to phishers in order to filter those confusing advertising spams in China and a neural network based model is proposed in order to detecting phishing messages from an e-mail stream. In this anti-phishing technique, email stream captured by our honey pot subsystem from the Internet is parsed into a MIME email firstly, various feathers are extracted from the email and outputted into feather vectors. The feature vectors will be self-organized by ART2 neural network one by one and classified into corresponding categories. Link URLs in the suspected emails' messages will be extracted for further detection in phishing site subsystem. Experiment using collected emails shows a good performance aiming at detecting phishing emails in China while foreign method performs badly in distinguishing phishing emails from spam.
