The XBee is a common wireless module that has become very popular amongst hobbyists and researchers alike due to its simple and efficient design. However, to use the XBee in complex networks, the user must construct specific packets to communicate within an XBee network. Here we will introduce an XBee C library which provides a modular, hardware-independent C library for XBee. Also using this library, we will explore establishing a framework for performing RSSI triangulation localization without the use of anchor nodes.","PeriodicalId":297826,"journal":{"name":"2014 11th Annual High Capacity Optical Networks and Emerging/Enabling Technologies (Photonics for Energy)","volume":"34 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":"132855262","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 strong photon emission from Al/Au/ NPB(N,N'-di(naphthalene-1-yl)- N,N'-diphenylbenzidine) /Alq3(tris8-hydroxyquinoline-aluminum)/LiF/Al and the symmetrical current-voltage curve for Al/LiF/Alq3/LiF/Al verify the hole-injecting anodic and the electron-injecting cathodic roles of Al(4 nm)/Au(7 nm) and Al(4 nm)/LiF(0.7 nm), respectively. The reflectivity spectrum is measured for viewing angles ranging from 5° to 50°. Experimental results show that when the viewing angle is increased from 5° to 50°, the reflectivity spectrum is blue shifted, which affects the contrast of HCT-OLEDs. Importantly, the measured average reflectivity in the visible range for viewing angles below 50° is as low as 6.6%, making the proposed HCT-OLEDs attractive for flat-panel-display applications.","PeriodicalId":297826,"journal":{"name":"2014 11th Annual High Capacity Optical Networks and Emerging/Enabling Technologies (Photonics for Energy)","volume":"39 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":"123351370","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}

An extension of mobile cloud computing, vehicular cloud computing, provides another viable solution, by consolidating the benefits of mobile cloud computing and vehicular communications. Among several challenges in this environment, privacy, service price and provision delay are the most important. In this paper, we propose a framework to address these challenges in a vehicular cloud based on a quality-of-experience (QoE) approach, discuss the drawbacks of existing architectures, and propose and validate a new architecture. This architecture is an extension of a system [1] we proposed in previous work. QoE is obtained via other mobile nodes in the vehicular cloud, and re-formulated according to a weighted combination of the three key factors: privacy, price and delay. Privacy is defined as a function of the information revealed to the service provider. We evaluate our proposal via simulations, and based on the numerical results, we show that QoE-based service provisioning in a vehicular cloud improves upon a naïve service provision approach, as well as other approaches that address only one of the factors.","PeriodicalId":297826,"journal":{"name":"2014 11th Annual High Capacity Optical Networks and Emerging/Enabling Technologies (Photonics for Energy)","volume":"18 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":"127881854","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 this approach, beside the tungsten source heat at high temperature, additional tungsten seed particles were dispersed on the substrate to promote the growth of nanowires. The surface oxidation of the tungsten seed particles induced the local growth of nanowire seeds, which were further developed into dense and long nanowire arrays by the vapor transport from the tungsten source. Systematic study on the oxidization of tungsten particles was performed and optimal conditions for the seed formation were analyzed by the comprehensive consideration of growth parameters (e.g., growth temperature, particle size, and oxygen flow rate). The WO3 nanowires specimens were characterized using scanning electron microscopy, energy dispersive X-ray spectroscopy, and X-ray diffraction. The seeded growth can enhance the growth of WO3 nanowires with controllable dimensions, providing a facile and scalable method for the growth of nanowires with large yield.","PeriodicalId":297826,"journal":{"name":"2014 11th Annual High Capacity Optical Networks and Emerging/Enabling Technologies (Photonics for Energy)","volume":"79 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":"126315943","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}

Hence, the total transmission capacity of designed HOTS is 4 Tb/s. Based on determined spectral channel width; a frequency grid for designed system was adopted that is tolerant for chromatic dispersion. The optimal architecture shows via simulations that only 10 regenerators and optical filters are required in a regeneration section to implement such a system.
