The paper takes up the issues of security, migration of applications from an internal data centre into cloud, scalability, billing and security. The paper thus points out the hardware incongruence for the cloud computing and presents key concepts for fabrication of VLSI chips. For example, the bills for cloud storage access is based on I/0 count. This metric is inaccurate since the cost of handling the bits varies from disk to disk. This arises due to variance of random access and sequential access used in disk. In sequential access, data is written to or read from one portion of the disk in a continual stream of bits. In random access, the disk head must jump around to different parts of the disk to read or write data. This disparity is immense since, sequential access can achieve a throughput on an average disk of up to 63.5MB/s (megabits per second), whereas random access can only be executed at 1.5MB/s. Techniques for reducing the random access and unnecessary metadata lookups are analyzed. The external threats for cloud from hardware hacking is attended and key alternatives are suggested for networking environment.","PeriodicalId":158960,"journal":{"name":"2011 International Conference on Electronics, Communication and Computing Technologies","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116590004","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}

In DWDM networks EDFA'S are an imperative elements and are regarded as a cost effective replacement of classical optoelectronic regenerative repeaters EDFA plays an important role in improvement of performance of optical fiber transmission systems. The proposed model consists of Input source with multiple channels, pumping source with the wavelengths 980nm or 1480nm and Isolator. The Erbium doped fiber amplifier's gain which appears in the signal to noise ratio expression is computed from the simulation. The resulting models accurately represent EDFA optimized gain. Simulation results, EDFA length of 10m and with 980nm pump of power 0.22W gives the gain of 40.17DB and for the same length of EDFA with 980nm pump of power 0.62W gives the optimized gain of 44.3DB and also with 980nm pump of power 1W gives the maximum optimized gain of 46DB and compared the results of Gain and noise figure with the wavelength of 1480nm and also with different lengths. This is applicable in Network reconfiguration and Multi-vendor networks and also addition of new services and wavelengths.","PeriodicalId":158960,"journal":{"name":"2011 International Conference on Electronics, Communication and Computing Technologies","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130781659","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}

It gets more attention in human face recognition. There are several proposals to develop systems that operate in the visible wavelength and in less constrained environments. These imaging conditions engender acquired noisy artefacts that lead to severely degraded images, making iris segmentation a major issue. Having observed that existing iris segmentation methods tend to fail in these challenging conditions, we present a segmentation method that can handle degraded images acquired in less constrained conditions. we offer the following contributions: first to consider the sclera the most easily distinguishable part of the eye in degraded images, then a new type of feature that measures the proportion of sclera in each direction and is fundamental in segmenting the iris, and finally to run the entire procedure in deterministically linear time in respect to the size of the image, making the procedure suitable for real-time applications. In this paper we discussed eye features normalisation and face detection for human identification.","PeriodicalId":158960,"journal":{"name":"2011 International Conference on Electronics, Communication and Computing Technologies","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117182561","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}

In earlier technologies, the labels or tags had to be scanned manually to capture the identity of the person/object. RFID, however, doesn't require manual scanning. An RFID system is generally made up of several readers with antennas which emit radio signals and capture back the signals emitted by tag. The context of our employee tracking application is we will provide each employee with RFID tag which correlates with two or more RFID reader which is placed inside the campus/office premises. The tag is activated with RF energy from the antennas that are placed in the chair of employees and it extracts information from the tag. Each tag has a unique ID. RFID reader converts the radio waves returned from the tag into a form that can be passed on to the controller. The data is updated at regular intervals in the host computer using wireless zigbee protocol (802.15.4). The delay is programmed using microcontroller. The performance of each employee is determined with the help of application software Visual Basic.","PeriodicalId":158960,"journal":{"name":"2011 International Conference on Electronics, Communication and Computing Technologies","volume":"188 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127667231","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}
