This reorganization is due to the need of a higher information transfer rate and a wider broadband, to be supported on a wireless platform. The aim is to have a private network for video, voice and data transmission using the Internet Protocol (IP), which is a data-oriented protocol used for communicating data across a packet switched network. The characteristics of the terrain allow us a detailed analysis of the reflections produced by the surface profile. The influence of the weather and the environment is also considered in the design.","PeriodicalId":380710,"journal":{"name":"2006 Multiconference on Electronics and Photonics","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116700001","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 set-up consists of two phase-modulated interference patterns incidents on semiconductor quantum well sample, each one creating its own photo-EMF signal that generate an electric signal corresponding in amplitude and frequency to the vibration. One of the interference patterns is phase-modulated by a vibrating object under test of unknown frequency and amplitude, the other one is modulated by a reference phase modulator of known frequency and amplitude. The interference patterns produce its own photo-EMF signal oscillating at different frequencies, resulting in a beating signal. When the frequency of both phase-modulated interference patterns is equal a sharp peak on the lock-in is measured, whose width is determined by the inverse of the time constant of the lock-in.","PeriodicalId":380710,"journal":{"name":"2006 Multiconference on Electronics and Photonics","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132196008","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}

Each detected cell is associated to its centroid in order to initialize the tracking procedure to quantify the migration process.
