It extends the reach and capacity of traditional PON from ~20 km to ~100 km using the optical amplifiers. It merges the metro and access domains by reducing the number of central offices (CO). This approach reduces capital and operational expenditure by reducing number of components, along with the network power consumption and design complexity. Transmission-messages are exchanged between the optical-line terminals and optical network units before the actual data transmission. By extending the reach, these messages are delayed due to increased Round Trip Time (RTT) which degrades the performance of dynamic bandwidth allocation (DBA) algorithms. Several schemes have been proposed to overcome such challenges. This paper presents a survey of different DBA schemes for Long Reach EPONs with their pros and cons. Comparative summary of these schemes is presented. We also discuss our proposed idea to enhance Quality of Service (QoS) with efficient DBA at the end of the paper.","PeriodicalId":297826,"journal":{"name":"2014 11th Annual High Capacity Optical Networks and Emerging/Enabling Technologies (Photonics for Energy)","volume":"71 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126102067","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 IEEE 802.11ac is an emerging WLAN standard which operates at 5GHz band. The real challenges for IEEE 802.11ac are to meet the recent functional demands and the extensive wireless market growth expected in next 3-5 years. The aim of this research is to propose an antenna design that can operate at 5GHz WLAN band and facilitates the features that conform to 802.11ac Wi-Fi standard requirements. The proposed antenna design consists of eight radiating elements and a gap coupled inset-feed technique is incorporated to achieve better performance by the MIMO antenna array. The dimensions of the patch antenna were calculated using transmission-line model whereas layouts of the single element antenna and the array are simulated on two different platforms i.e. momentum - an EM tool of Agilent's advance design system (ADS) system simulator based on method of moments technique and CST microwave studio which is based on finite difference time domain technique. In the end, the comparative analysis of the antenna simulation results using both the techniques is presented.","PeriodicalId":297826,"journal":{"name":"2014 11th Annual High Capacity Optical Networks and Emerging/Enabling Technologies (Photonics for Energy)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126641515","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}

To do this, service providers must understand the tradeoffs within provisioning algorithms such as utilization versus system availability or the impact of service level agreement timescale on utilization. Within the context of three provisioning algorithms from existing literature, we analyze the tradeoff of service availability versus utilization using a two-dimensional Pareto analysis. We also analyze the impact on utilization and system availability of using hourly, daily, weekly, or yearlong timescales as the basis of service level agreement. We evaluate model performance using historical data of the Virtual Computing Laboratory (VCL), a cloud computing environment at North Carolina State University. We show that a simple heuristic planning model, whereby a fixed reserve capacity is maintained, provides better service availability and utilization performance than other models for all service level timescales. The fixed reserve capacity model is also shown to be Pareto optimal.","PeriodicalId":297826,"journal":{"name":"2014 11th Annual High Capacity Optical Networks and Emerging/Enabling Technologies (Photonics for Energy)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114578720","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}

Multiple Graphene quilts were used to create extra heat escape channels for efficient heat dissipation. An array comprises of ten-chips on sapphire substrate and two district packages were considered as a control and test accordingly. The two-test designs consisting of one-quilt per device, and multi-quilts per device, respectively were modeled using ANSYS13™ and on-chip steady-state thermal analysis technique. Results were used to evaluate chips temperature for their operation power levels. Comparative study was also performed for the heat dissipation related improvements for the case of Graphene when introduced heat spreaders. A temperature drop of ~8 °C for one-quilt and 15 °C for multi-quilt chips was achieved for 5mW powers, respectively. We conclude that implementation of Graphene heat spreaders in micro-LED arrays has significant effects on devices heat management and thermal stability. This work also shows the potential of the 2D carbon structures in photonics and electronics manufacturing industry.","PeriodicalId":297826,"journal":{"name":"2014 11th Annual High Capacity Optical Networks and Emerging/Enabling Technologies (Photonics for Energy)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133675988","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}

SEM images show generation of nano size particles at the surface after 120 min exposure with alpha irradiation and the size increases with further exposure of the radiations.
