ANALISA IMPLEMENTASI VIDEOCONFERENCE BERBASIS IP ANALYSIS OF IMPLEMENTATION VIDEOCONFERENCE BASED ON IP

ABSTRAKSI: Layanan Videoconference berkembang dengan pesat. Hal ini dikarenakan semakin meningkatnya kebutuhan komunikasi tatap muka. Seiring dengan perkembangan teknologi kearah teknologi IP maka teknologi Videoconference sekarang juga berkembang kearah teknologi IP. Namun demikian, implementasi Videoconference khususnya pada jaringan IP masih memiliki beberapa kendala antara lain jaminan QoS, sehingga sampai sekarang implementasi Videoconference masih pada jaringan Close IP belum sampai pada Public IP. Pada proyek akhir ini akan dianalisa teknologi Videoconference berbasis IP dan  hal – hal yang harus dipenuhi untuk mengimplementasikan Videoconference pada jaringan IP dengan melihat parameter Packet Loss, Jitter dan Latency.Hasil dari analisa memberikan suatu kesimpulan tentang Videoconference berbasis IP dan bagaimana mengimplementasikan Videoconference pada Jaringan IP sesuai standar H.323.  Kata Kunci : -ABSTRACT: Because the necessity of communication face to face is increase, who’s made videoconference services growth rapidly. As long as the development of technology strive to the IP technology it make the technology of videoconference developed to the IP technology too. Which the implementation of videoconference especially on IP network still has the obstacle in QoS, it makes the videoconference can’t implemented through the IP public, still on the Close IP. With this final project will analyzes the videoconference technology based on IP and with all the parameter requeried, like Packet Loss, Jitter and Latency to make the IP network can be implemented with videoconference. The result of this analyzes gaves the conclusion of vidoeconference based on IP and how to implemented the videoconference on IP network appropriate with H.323 standart.  Keyword:

Social Capital and the Transition to College for Asian Americans

Asian Americans are generally perceived to be disproportionately enrolled in four-year postsecondary education institutions despite evidence of Asian Americans being concentrated at both two-year and four-year postsecondary education institutions. This perception of Asian Americans has contributed to limited attention to Asian Americans’ transition to college. To better understand the transition to college for Asian Americans, this study explored if social capital is related to four-year college enrollment and the highest level of educational expectation. Whites were included in the study for comparative purposes. The main research question focuses on the extent demographic characteristics, access to, and mobilization of social capital from the social networks of family, peers, and school predict enrollment in a four-year postsecondary education institution. This study also examined the strongest predictors for the highest level of education expected three years after completion of high school. Lin’s Network Theory of Social Capital served as the theoretical framework. The data came from the public-use file of the High School Longitudinal Studies of 2009 (HSLS:09). Logistic regression and discriminant function analysis were employed in the analyses. Balanced Repeated Replication variance estimation and replicate weights were used to able to generalize from the Asian American subpopulation sample size of 1,952 to a nationally representative Asian American sample size of 142,405 and from the White subpopulation sample size of 12,082 to a nationally representative White sample size of over 2.1 million. The results suggest that socioeconomic status partly explains the educational enrollment patterns of Asian Americans and Whites. Asian Americans and Whites from the highest socioeconomic status are more likely to enroll in a four-year postsecondary than Asian Americans and Whites from the lowest socioeconomic status. Socioeconomic status also partly explains the highest level of education Asian Americans and Whites expected three years after completing high school. In general, Asian Americans and Whites from higher socioeconomic status have higher educational expectations. The results also suggest that access to social capital is a significant predictor of four-year college enrollment. However, access to the form of social capital matters, particularly for Asian Americans. Access to family social capital in the form of congruent degree expectations, where parents and students share the same educational expectations of the student earning at least a bachelor’s degree, increased the odds of a four-year college enrollment for both Asian Americans and Whites. However, it was the only form of social capital that was significant in explaining the four-year college enrollment for Asian Americans. The forms of social capital that were significant in explaining four-year college enrollment for Whites, specifically access to family social capital in the form of family involvement, access to peer social capital, and access to school social capital were not significant predictors for Asian Americans. The findings suggest that the student-parent relationship is important in the transition to college, especially so for Asian Americans. Additionally, the combination of the findings suggests that practices and policies that take socioeconomic status into account and are racially and culturally informed are important in supporting Asian Americans in the transition to college

Risk and Value in Privately Financed Health care Projects

An empirical study is presented to investigate the risk factors affecting the value for money that can be obtained from using the public-private partnership delivery system to develop social facility projects. Based on a model describing the main risks affecting a project, a linear regression analysis is conducted on a dataset of privately financed healthcare projects in the UK to explore the main factors that might have significant relationships with the annual unitary charge payment. The results reveal that the economic and political environment, the hospital capacity, the construction duration, and the concession period are significant factors of the price paid by the granting authority. The study confirms that the unitary charge is not only affected by investment, operations and financial lifecycle costs, but also by risk factors and the level of risk allocated to the private sponsors. The proposed methodology might help both public and private parties in improving PFI project's compensation design, in order to achieve a higher value in privately financed infrastructures. The given model might also support the process of better determining the amount of annual payment based on select drivers and appropriately transferred risk factor

Crystal structure of Li_2B_(12)H_(12): a possible intermediate species in the decomposition of LiBH_4

The crystal structure of solvent-free Li_2B_(12)H_(12) has been determined by powder X-ray diffraction and confirmed by a combination of neutron vibrational spectroscopy and first-principles calculations. This compound is a possible intermediate in the dehydrogenation of LiBH_4, and its structural characterization is crucial for understanding the decomposition and regeneration of LiBH_4. Our results reveal that the structure of Li_2B_(12)H_(12) differs from other known alkali-metal (K, Rb, and Cs) derivatives

The experience of young people transitioning between youth offending services to probation services

Jayne Price, The experience of young people transitioning between youth offending services to probation services, Probation Journal (Vol. 67 Iss. 3) pp. 246-263. Copyright © 2020 (SAGE). Reprinted by permission of SAGE Publications.This article explores the experience of transitioning from youth offending services to adult probation services upon turning age 18 years whilst incarcerated. The significant differences in the level of provision has been described as a ‘cliff-edge’ (Transition to Adulthood Alliance, 2009). Drawing upon interviews with young people held in institutions, stakeholders and survey data from Her Majesty’s Inspectorate of Prisons (HMIP), it is argued that the drop in support is exacerbated by poor communication between institutions and services which has harmful implications for young people during this crucial period of developmental maturity and beyond custody

Multiple‐systems analysis for the quantification of modern slavery: classical and Bayesian approaches

Multiple systems estimation is a key approach for quantifying hidden populations such as the number of victims of modern slavery. The UK Government published an estimate of 10,000 to 13,000 victims, constructed by the present author, as part of the strategy leading to the Modern Slavery Act 2015. This estimate was obtained by a stepwise multiple systems method based on six lists. Further investigation shows that a small proportion of the possible models give rather different answers, and that other model fitting approaches may choose one of these. Three data sets collected in the field of modern slavery, together with a data set about the death toll in the Kosovo conflict, are used to investigate the stability and robustness of various multiple systems estimate methods. The crucial aspect is the way that interactions between lists are modelled, because these can substantially affect the results. Model selection and Bayesian approaches are considered in detail, in particular to assess their stability and robustness when applied to real modern slavery data. A new Markov Chain Monte Carlo Bayesian approach is developed; overall, this gives robust and stable results at least for the examples considered. The software and datasets are freely and publicly available to facilitate wider implementation and further research

Anomalous pressure effect on the magnetic ordering in multiferroic BiMnO3

We report the magnetic field dependent dc magnetization and the pressure-dependent (pmax ~ 16 kbar) ac susceptibilities Xp(T) on both powder and bulk multiferroic BiMnO3 samples, synthesized in different batches under high pressure. A clear ferromagnetic (FM) transition is observed at TC ~ 100 K, and increases with magnetic field. The magnetic hysteresis behavior is similar to that of a soft ferromagnet. Ac susceptibility data indicate that both the FM peak and its temperature (TC) decrease simultaneously with increasing pressure. Interestingly, above a certain pressure (9 ~ 11 kbar), another peak appears at Tp ~ 93 K, which also decreases with increasing pressure, with both these peaks persisting over some intermediate pressure range (9 ~ 13 kbar). The FM peak disappears with further application of pressure; however, the second peak survives until present pressure limit (pmax ~ 16 kbar). These features are considered to originate from the complex interplay of the magnetic and orbital structure of BiMnO3 being affected by pressure.Comment: 4 pages,4 figures, publised in Physical Review B 78, 092404/200
