Moreover, Russian is highly inflectional language with rich morphology, which leads to high out-of-vocabulary word rates. Recently factored language model (FLM) was proposed with the aim of addressing the problems of morphologically rich languages. In this paper, we describe our implementation of the FLM for the Russian language automatic speech recognition (ASR). We investigated the effect of different factors, and propose a strategy to find the best factor set and back-off path. Evaluation experiments showed that FLM can decrease the perplexity as much as 20%. This allows to achieve 4.0% word error rate (WER) relative reduction, which further increases to 6.9% when FLM is interpolated with the conventional 3-gram LM.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":"108 1","pages":"205-211"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77290010","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}

This paper adopts the time-variant community mobility model to formulate the relationship between user mobility and social community in delay-tolerant networks. With synthetic trace data of various user mobility and community patterns, simulation results show that the proposed model is able to interpret many characteristics of movement behavior and social community structure, accordingly, with a friendly graphic presentation. Therefore, the proposed analysis model can be applied to facilitate the design of social-based data dissemination mechanisms in delay-tolerant networks.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":"457 1","pages":"685-691"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76692327","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}

However, the complexity of web-pages is increasing especially if the web-pages are designed for desktop computers. The existence of advertisements (ads) in web-page leads to even higher complexity of the web-pages. This complexity in smartphone's environment where the resources are limited (e.g., battery and bandwidth) is reflected in longer loading time, more energy consumed, and more bytes transferred. In this paper, we classify the web contents into: (i) core information, and (ii) forced \"unwanted\" information, namely ads. Then, we evaluate resources used for web advertising. Based on the measurements of the cost of web advertising, we propose a framework for mobile browsing that adapts the web-pages delivered to the smartphone, based on the smartphone's current battery level and the network type. The adaptation of the web content is in the form of controlling the amount of ads to be displayed on the web-page. Our system aims to (i) extend smartphone battery life and (ii) preserve the bandwidth needed to download the web-pages while balancing the satisfaction of the publishers of web-pages as well as the end users.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":"7 1","pages":"671-679"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84845891","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 advance technologies are needed to match the demand of the development of cloud computing. MapReduce is one of the enabling technology. MapReduce is a programming model supporting parallel computation especially for data-intensive cloud computing applications. However, MapReduce needs a master node to coordinate the execution of the parallel computation. This may cause communication bottleneck and single point of failure error.

This FTP can let a computer system connect to the internet via a communication network, and it can also access the system resources from the internet. File server is being downloaded now by TCP/IP protocol, while before it was downloaded by signal server. Due to the limited flow control, the old method could not use download time efficiently. In order to solve the flow control problem, some researchers came up with a distributed file transfer method that can share the document with other users, thus allowing the shortest transfer time using neighboring servers. Although the distributed file transfer can reduce the file transfer time, it was not concerned with the quality of the transfer between two servers, and was inappropriate for file segmentation and transfer, so the file transfer could not attain the optimal transfer efficacy. Based on our research, we propose a new method called Distributed Parallelized File Transfer Protocol (DPFTP). This method is based on Parallelized File Transfer Protocol (P-FTP) and is beneficial to multi-users, as it utilizes server loading and reduces the download time.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":"9 1","pages":"718-724"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78474942","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}

These sensor nodes are sometimes random deployed, so they have to be aware to their location before starting their tasks. Most sensor nodes need hardware support or receive packets with location information to estimate their location, and this needs lots of time or costs, and may have a huge error. In this paper we present a localization mechanism in wireless sensor networks (MRN). This mechanism can cooperate with node localization algorithm and mobile reference node moving direction scheme. We use a mobile reference node with GPS to move to the whole environment, and we use RSSI and trilateration to estimate unknown nodes' location. We can obtain more unknown nodes location by mobile reference node moving scheme, and will decreases the energy consumption and average location error.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":"6 1","pages":"747-753"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79077162","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}

A typical load balancing technique is to use a dedicated load balancer to forward the client requests to different servers, this technique requires dedicated hardware support, the hardware is expensive, lacks of flexibility and is easy to become a single point failure. There will be a new solution for load balancing with OpenFlow proposed., this paper mainly studies dynamic load balancing technology in the OpenFlow environment, the Controller collected the server running status through the SNMP protocol, and calculated the aggregated load of the severs according to dynamic load balancing scheduling algorithm, the OpenFlow switch will forward the client's request to the server whose aggregated load is smallest, thus minimize the response time of the web server.

When listener's ear level is different with loudspeakers, it will cause difficulty of sound localization or breakdown of sound localization.
