    Time and frequency characterization of the high speed I/O data bus

    Get PDF
    High speed data transfer between the CPU and peripherals on the PC motherboard is needed to support data traffic in future generation applications such as multimedia, games and broadband networks. The High Speed I/O data bus is developed to meet these applications. At high speed with multi Gbits/sec, impedance mismatch between the CPU and peripherals becomes critical and limits the possible maximum throughput. This effect can be modeled as a convolution process where the I/O bus behaves as a linear time invariant system that is defined by a channel impulse and frequency response. Since there are variations in the characteristic of the motherboards due to the fabrication and assembly process, it is desired to estimate the impulse response and frequency response of the High Speed I/O bus. This information can be used to gage the capability of the motherboard and use it as feedback to the relevant fabrication and assembly processes. By using simulation on MATLAB and EDA tools, two candidate methods will be evaluated: Impulse response and correlation method using simulated channel characteristics. Robustness of both methods will be evaluated in the presence of noise and cross talk. Further evaluation will be performed on data collected from actual production test of the I/O Bus. This is to evaluate the capability of the evaluated methods under actual manufacturing environment

    lessons relearnt The first volume of Late lessons from early warnings was published in 2001. Since then, the world has changed significantly. It is larger in population but smaller in interconnectivity; faster in terms of technology adoption but slower in terms of policy action in the face of complex interlinked problems; more volatile in terms of economic and environmental changes, yet more static in terms of political reflexivity and adaptations in governance. Beyond the current financial and economic crises, there are several long-term, systemic and interconnected challenges, such as depletion of natural resources, climate change, a 2-billion person increase in the world population by 2050

    This study was an attempt to answer the questions: Are the words used in the compositions of Writing I students specific and appropriate? Are the nouns, adjectives, verbs, and adverbs used in the compositions under study specific and appropriate? The data source of the study was the students' Writing I final test papers of academic years 2006/2007 (15 papers) and 2008/2009 (15 papers). The results are the words made by the students from both academics are specific and appropriate in which the score is 3. There are 20 essays scored 3 or in good quality, 7 essays with excellent score (4), and 3 essays are scored 2 (fair). The nouns used are specific (good score of 3) while the verbs and the modifiers used are somewhat specific (fair score of 2). All four classwords are used appropriately in which the score is 4 (excellent). Based on the results, it is suggested the EESP authorities include vocabulary section in Writing I syllabus that is treated as equally important as any other elements of Writing. The Writing I lecturers are expected to teach the students to master and use specific and appropriate words. The students themselves are encouraged to enrich their vocabularies by reading books

    Inelastic current-voltage characteristics of atomic and molecular junctions

    Full text link
    We report first-principles calculations of the inelastic current-voltage (I-V) characteristics of a gold point contact and a molecular junction in the nonresonant regime. Discontinuities in the I-V curves appear in correspondence to the normal modes of the structures. Due to the quasi-one-dimensional nature of these systems, specific modes with large longitudinal component dominate the inelastic I-V curves. In the case of the gold point contact, our results are in good agreement with recent experimental data. For the molecular junction, we find that the inelastic I-V curves are quite sensitive to the structure of the contact between the molecule and the electrodes thus providing a powerful tool to extract the bonding geometry in molecular wires.Comment: 4 pages, 3 figure

    In Vitro Propagation Of Vanilla (Vanilla Planifolia Andr.) On Different Concentration Of Cytokinins

    Micropropagation of vanilla was conducted through excised apical shoot tip and nodal segment as explants to determine the best concentration of growth hormone of cytokinin on multiple shoots production and regeneration. The explants were cultured on MS medium augmented with different concentration of N6-Benzyladenin and Kinetin. Sub culture was done four weeks after inoculation to regenerate more elongated shoots on the medium containing the same concentration of plant growth regulators as inoculation medium. After 60 days of cultured, multiple regenerated shoots were elongated and formed leaves and roots. The two cytokinins tested induced bud break to different degrees. Among the various concentrations tested N6-Benzyladenin at 1.5 mg.l-1 gave the highest mean shoot number (3.27/explant) and leaves (3.80/shoot) differentiation. While the lowest number of shoots and leaves were found on MS medium fortified with 1.0 mg.l-1 Kinetin. All cultures produced roots and the highest number of roots formed on the medium containing 2 mg.l-1 Kinetin. &nbsp

    This Community Service aims to improve the knowledge of postpartum mothers about protein-rich nutrition and factors that can inhibit iron absorption. The methods used include counseling, teaching the preparation of snakehead fish nuggets, and health examinations. This activity was conducted in Sereh Village, Sentani, from May to November 2023, with stages including leaflet distribution, nutritional counseling, and hemoglobin level checks before and after consuming nuggets for 14 days. Prior to the main activities, a trial for nugget preparation was conducted, followed by home visits for observation and evaluation. The hemoglobin level checks revealed that 10 (38.46%) postpartum and breastfeeding mothers experienced mild anemia, while 16 (61.54%) did not have anemia, with an average hemoglobin level of 10.196 g/dl. After consuming 100 grams of nuggets daily for 14 days, changes in hemoglobin levels were observed, with mothers who previously experienced mild anemia transitioning to a non-anemic status. The average hemoglobin level after consuming snakehead fish nuggets was 12.308 g/dl, with an average increase of 2.116 g/dl before and after nugget consumption. The conclusion of this community service activity indicates that postpartum mothers experienced an increase in knowledge regarding the importance of protein-rich nutrition and factors that can inhibit iron absorption
