    Electronic Dance Music Culture’s Communication Transition Through Social Media in North America

    Get PDF
    The project aims to link the past modes of communication utilized by participants in electronic dance music (EDM) club cultures and subcultures, to the current practice of using various social media platforms as a means of information conveyance about musicians, producers, DJs, events, and industry-related news. It will attempt to determine to what degree social media platforms influence electronic dance music culture, the positive and negative effects social media has on the culture, and whether the transition to digital communication modes is absolute. Finally, it will pose the question as to whether any further research on social media usage among EDM fans will be or has been performed as a result of the recent media consensus that the mainstream EDM bubble has burst, and that North America is on the precipice of a post-EDM future

    Large-Scale Graphene Film Deposition for Monolithic Device Fabrication

    Since 1958, the concept of integrated circuit (IC) has achieved great technological developments and helped in shrinking electronic devices. Nowadays, an IC consists of more than a million of compacted transistors. The majority of current ICs use silicon as a semiconductor material. According to Moore\u27s law, the number of transistors built-in on a microchip can be double every two years. However, silicon device manufacturing reaches its physical limits. To explain, there is a new trend to shrinking circuitry to seven nanometers where a lot of unknown quantum effects such as tunneling effect can not be controlled. Hence, there is an urgent need for a new platform material to replace Si. Graphene is considered a promising material with enormous potential applications in many electronic and optoelectronics devices due to its superior properties. There are several techniques to produce graphene films. Among these techniques, chemical vapor deposition (CVD) offers a very convenient method to fabricate films for large-scale graphene films. Though CVD method is suitable for large area growth of graphene, the need for transferring a graphene film to silicon-based substrates is required. Furthermore, the graphene films thus achieved are, in fact, not single crystalline. Also, graphene fabrication utilizing Cu and Ni at high growth temperature contaminates the substrate that holds Si CMOS circuitry and CVD chamber as well. So, lowering the deposition temperature is another technological milestone for the successful adoption of graphene in integrated circuits fabrication. In this research, direct large-scale graphene film fabrication on silicon based platform (i.e. SiO2 and Si3N4) at low temperature was achieved. With a focus on low-temperature graphene growth, hot-filament chemical vapor deposition (HF-CVD) was utilized to synthesize graphene film using 200 nm thick nickel film. Raman spectroscopy was utilized to examine graphene formation on the bottom side of the Ni film and on the silicon-based substrate. Large- area bilayer graphene film was formed on silicon based platform. COMSOL Multiphysics was used to investigate the CVD graphene growth on Ni films. Factors affecting CVD graphene synthesis include carbon solubility in Ni, growth time, growth temperature, as well as Ni film thickness. COMSOL model uses transport of diluted species, heat transfer in Ni thin film as well as deformed geometry module. In this particular research, the number of simulated graphene layers on Ni film was compared with experimental data. Also, the effect of many CVD parameters on graphene film fabrication is stated. In conclusion, a novel method for direct large-scale graphene film fabrication on silicon based platform at low temperature was achieved using hot-filament chemical vapor deposition

    The role of social worker in the success of social integration for disabled children Analytical study in the reality of Jordanian society

    The study aimed at understanding the role of the social worker in the process of social integration for disabled children in Jordan through different programs and institutions because of the local and global awareness of the necessity for integrated programs for disabled children. It also aimed at integrating and activating children in the process of rehabilitation in order to regain their interaction, adaptation and productivity; so the special disabled can play an active and positive role in their community.  The study found that the social worker job with disabled children and with their environment that they interact with; play a significant role in developing the social skills for disabled children and in preparing the society to accept them as an active member in their society. Key Words: The role, disabled children, social integration. DOI: 10.7176/RHSS/10-8-05 Publication date: April 30th 202

    Standardized Versus Naturalized: An Evaluation of Child Morphological and Syntactic Assessments

    Get PDF
    Speech-language pathologists may choose to evaluate children’s language using standardized or naturalized assessments. This study investigated if the Clinical Evaluation of Language Fundamentals-Preschool 2 (CELF-P 2), a standardized assessment, and language sampling, a naturalized assessment, reveal the same information about children’s linguistic competence and performance. Children ages 3.0-7.0 were assessed with specific focus on morphology and syntax. The participants completed four morphosyntactic-based subtests of the CELF-P 2. Additionally, play-based interactions, used to elicit natural language, were video-recorded. The CELF-P 2 was scored and language samples were transcribed and analyzed. Mean length of utterance (MLU) scores showed a slightly more variable trend around the mean than CELF-P 2 scores and there were no significant correlations between the two assessments. Furthermore, the two forms of assessment produced incongruous age equivalents for 66% of the participants (four out of six) and participants produced different morphosyntactic structures during each type of assessment. Thus, results indicated limitations and successes of the different assessment approaches. When used alone, either form of assessment did not provide a completely accurate representation of children’s language acquisition. However, when used in conjunction, the two assessments may represent the linguistic competence and performance of children more accurately.Faculty Sponsor: Dr. Dorothy Leone, Ph.D., CCC-SL

    A self-adapting latency/power tradeoff model for replicated search engines

    Get PDF
    For many search settings, distributed/replicated search engines deploy a large number of machines to ensure efficient retrieval. This paper investigates how the power consumption of a replicated search engine can be automatically reduced when the system has low contention, without compromising its efficiency. We propose a novel self-adapting model to analyse the trade-off between latency and power consumption for distributed search engines. When query volumes are high and there is contention for the resources, the model automatically increases the necessary number of active machines in the system to maintain acceptable query response times. On the other hand, when the load of the system is low and the queries can be served easily, the model is able to reduce the number of active machines, leading to power savings. The model bases its decisions on examining the current and historical query loads of the search engine. Our proposal is formulated as a general dynamic decision problem, which can be quickly solved by dynamic programming in response to changing query loads. Thorough experiments are conducted to validate the usefulness of the proposed adaptive model using historical Web search traffic submitted to a commercial search engine. Our results show that our proposed self-adapting model can achieve an energy saving of 33% while only degrading mean query completion time by 10 ms compared to a baseline that provisions replicas based on a previous day's traffic
