3GPP Long Term Evolution LTE Scheduling

3GPP Long Term Evolution LTE Scheduling

Date: December 2013
Creator: Alotaibi, Sultan
Description: Future generation cellular networks are expected to deliver an omnipresent broadband access network for an endlessly increasing number of subscribers. Long term Evolution (LTE) represents a significant milestone towards wireless networks known as 4G cellular networks. A key feature of LTE is the implementation of enhanced Radio Resource Management (RRM) mechanism to improve the system performance. The structure of LTE networks was simplified by diminishing the number of the nodes of the core network. Also, the design of the radio protocol architecture is quite unique. In order to achieve high data rate in LTE, 3rd Generation Partnership Project (3GPP) has selected Orthogonal Frequency Division Multiplexing (OFDM) as an appropriate scheme in terms of downlinks. However, the proper scheme for an uplink is the Single-Carrier Frequency Domain Multiple Access due to the peak-to-average-power-ratio (PAPR) constraint. LTE packet scheduling plays a primary role as part of RRM to improve the system’s data rate as well as supporting various QoS requirements of mobile services. The major function of the LTE packet scheduler is to assign Physical Resource Blocks (PRBs) to mobile User Equipment (UE). In our work, we formed a proposed packet scheduler algorithm. The proposed scheduler algorithm acts based on the number ...

Novel Semi-Conductor Material Systems: Molecular Beam Epitaxial Growth and Characterization

Novel Semi-Conductor Material Systems: Molecular Beam Epitaxial Growth and Characterization

Date: December 2013
Creator: Elmarhoumi, Nader M.
Description: Semi-conductor industry relies heavily on silicon (Si). However, Si is not a direct-band gap semi-conductor. Consequently, Si does not possess great versatility for multi-functional applications in comparison with the direct band-gap III-V semi-conductors such as GaAs. To bridge this gap, what is ideally required is a semi-conductor material system that is based on silicon, but has significantly greater versatility. While sparsely studied, the semi-conducting silicides material systems offer great potential. Thus, I focused on the growth and structural characterization of ruthenium silicide and osmium silicide material systems. I also characterized iron silicon germanide films using extended x-ray absorption fine structure (EXAFS) to reveal phase, semi-conducting behavior, and to calculate nearest neighbor distances. The choice of these silicides material systems was due to their theoretically predicted and/or experimentally reported direct band gaps. However, the challenge was the existence of more than one stable phase/stoichiometric ratio of these materials. In order to possess the greatest control over the growth process, molecular beam epitaxy (MBE) has been employed. Structural and film quality comparisons of as-grown versus annealed films of ruthenium silicide are presented. Structural characterization and film quality of MBE grown ruthenium silicide and osmium silicide films via in situ and ex situ ...

Quality Assurance Practices in Web Archiving

Quality Assurance Practices in Web Archiving

Date: December 2014
Creator: Reyes Ayala, Brenda; Phillips, Mark Edward & Ko, Lauren
Description: This dataset contains the results of a survey of quality assurance practices within the field of web archiving and its practitioners. To understand current QA practices, the authors surveyed institutions engaged in web archiving, which included national libraries, colleges and universities, and museums and art libraries. The survey was administered online. It includes the completed responses of 54 participants. The data has been anonymized for privacy reasons. This dataset was used in the "Current Quality Assurance Practices in Web Archiving" paper, available from the UNT Digital Library.
