Error Tolerant Video Transmission using FEC and Multi-level Coding

Riley, Martyn J.,Irichardson, ain E. G. 대한전자공학회 1994 ISPACS:Intelligent Signal Processing and Communica Vol.1 No.1

Emerging communication networks based on the Asynchronous Transfer Mode (ATM)' are designed to support the transport of real-time compressed video traffic. At times of congestion, buffer overflow can occur, and cells are lost. Compressed video traffic is extremely sensitive to data loss. Recently Forward Error Correction (FEt) has been suggested as a means of recovering ATM cell loss during the transmission of compressed video. We investigate rodeo compressed using two different operating modes of the JPEG International Standard. We consider the base-line and the Progressive Spectral Selection (PSS) mode of the JPEG standard. The PSS JPEG algorithm allows video to be compressed into a number of separate spatial frequency bands or scans, each scan consisting of a different sequence of coded Discrete Cosine Transform (DCT) coefficients. We have shown' that each scan exhibits a different tolerance to cell loss. Therefore, we add varying amounts of FEC parity information to each of the scans depending on their sensitivity to cell loss. We compare the PSS JPEG algorithm, with varying quantities of FEC on each scan, to the base-Line JPEG algorithm, with a constant amount of FEC added across all spatial frequencies. We perform an experiment to transmit a number of coded video sequences resulting from real traffic streams through a simple simulated ATM network which introduces a high level of cell loss. We re-animate the received traffic streams and perform subjective quality evaluation.

ANALYSIS OF EQUILIBRIUM METHODS FOR THE COMPUTATIONAL MODEL OF THE MARK-IV ELECTR OREFINER

RILEY CUMBERLAND,ROBERT HOOVER,SUPATHORN PHONGIKAROON,임만성 한국원자력학회 2011 Nuclear Engineering and Technology Vol.43 No.6

Two computational methods for determining equilibrium states for the Mark-IV electrorefiner (ER) have been assessed to improve the current computational electrorefiner model developed at University of Idaho. Both methods were validated against measured data to better understand their effects on the calculation of the equilibrium compositions in the ER. In addition, a sensitivity study was performed on the effect of specific unknown activity coefficients—including sodium in molten cadmium, zirconium in molten cadmium, and sodium chloride in molten LiCl-KCl. Both computational methods produced identical results, which stayed within the 95% confidence interval of the experimental data. Furthermore, sensitivity to unavailable activity coefficients was found to be low (a change in concentration of less than 3 ppm).

A Multilateral Approach to Investor-State Dispute Settlement Issues in the Asia-Pacific Region

Riley John 이준국제법연구원 2021 Journal of East Asia and International Law Vol.14 No.1

Bilateral agreements are not the optimal solution to address modern challenges regarding the resolution of investment disputes. The time has come for multilateral agreements to define a clear procedure for resolving investment disputes and the formation of arbitration for these purposes. On November 15, 2020, ASEAN members and five regional partners signed the Regional Comprehensive Economic Partnership (RCEP), arguably the largest free trade agreement in history. Although the RCEP agreement defines the basic principles of legal protection of investments, it does not contain a procedure for settling disputes directly between investors and parties to the agreement, i.e., Investor-State Dispute Settlement (ISDS), but rather postpones the issue for future negotiations. Nevertheless, a majority of countries understand the importance of investment protection and have significant outward FDI that will support stronger ISDS protections within a multilateral framework. Therefore, it is recommended that in the near future member countries will come to an agreement and adopt appropriate amendments to the RCEP regarding ISDS.

Black Tea Exhibits a Dose-Dependent Response in Saos-2 Cell Mineralization

Riley E. Cleverdon,Michael D. McAlpine,Wendy E. Ward 한국식품영양과학회 2020 Journal of medicinal food Vol.23 No.9

Higher bone mineral density (BMD) is often associated with greater consumption of black tea (BT). However, the dose–response of BT on mineralization in an osteoblast cell model has not yet been studied. The study objective was to determine the dose-dependent response of BT in Saos-2 cells and investigate changes to several proteins involved in the mineralization process. Mineralization was induced in the presence of BT at concentrations that represent levels likely achieved through daily consumption (0.1, 0.5, 0.75, 1 μg gallic acid equivalents [GAE]/mL) or through supplementation (2, 5, or 10 μg GAE/mL). BT exerted a positive dose–response on bone mineralization, peaking at 1 μg GAE/mL of BT (P < .05). Cellular activity was significantly greater than control with exposure to 2–10 μg GAE/mL of BT (at 24 h) (P < .05) and 1–10 μg GAE/mL (at 48 h) (P < .05), with a peak at 5 μg GAE/mL at 24 and 48 h (P < .05). Protein expression of alkaline phosphatase and ectonucleotide pyrophosphatase/phosphodiesterase-1 were unchanged, whereas a moderate dose of BT (0.75 μg GAE/mL) resulted in greater expression of osteopontin compared with the highest dose (10 μg GAE/mL) (P < .05). Doses of BT from 0.5 to 10 μg GAE/mL resulted in higher antioxidant capacity compared with control (P < .05). In summary, the higher antioxidant capacity, enhanced cell viability, and upregulated mineralization suggest that consumption of BT may have a positive effect on BMD at levels obtained through consumption of tea.

Sustaining customer engagement through social media brand communities

Jen Riley 한국마케팅과학회 2020 마케팅과학연구 Vol.30 No.4

Customers are spending an exorbitant amount of time engaging various media outlets. Due to technological advances such as social media, marketers must innovate to stay top-of-mind for customers and approach the customer engagement journey differently. Social media allows brands to facilitate traditional offline brand communities, virtually. However, sustaining that engagement often presents a challenge and can be a strain on the resources of a company and marketing team. Allowing customers to engage with other customers and brands gives social media brand communities a unique competitive advantage over other marketing methods. By engaging in content creation within social media brand communities, customers and marketers are able to co-create value and increase customer engagement. Transferring part of the customer engagement experience into an online setting provides value cocreation opportunities among customers and for the brand. This manuscript proposes a framework for sustaining social media brand communities and customer engagement for value co-creation.

An Analysis of Child Abuse Laws in Korea

John Riley 경희대학교 법학연구소 2016 경희법학 Vol.51 No.4

Despite many changes to the law in recent years, child abuse continues present significant social and legal challenges in Korea. Because the overwhelming majority of child abuse occurs within the home, it has been difficult for society to grapple with the proper balance between parental rights versus the right of children to live in a safe environment. Although child abuse has existed for centuries, its recognition and understanding by the medical and legal communities is a relatively recent phenomenon, and measures to lower the incidents of abuse varies greatly across countries. This paper seeks to analyze the development of laws designed to reduce the occurrence of child abuse from a domestic and international perspective. Part I introduces the current international definition of child abuse and its harmful effects, including an explanation of the Battered Child Syndrome (BCS), which explains the characteristics of children who have been exposed to repeated instances of abuse. Part II explains how BCS has raised public awareness of the serious plight of abused children, which has resulted in laws and protective agencies in the US, as well as the use of expert testimony in child abuse case and self-defense cases. Part III discusses the 1989 UN Convention on the Rights of the Child and its implementation in Korea through various legislative developments. Part IV reviews various articles of the Korea Criminal Code and suggests that certain provisions remain heavily influenced by traditional notions of Confucianism that are at odds with contemporary democratic principles. Part V analyzes several Korea Supreme Court and Constitutional Court cases that have focused on the parent-child relationship and demonstrate the judiciary's difficulty in reconciling traditional notions of filial piety while protecting equal protection regardless of one's hierarchical status within the family. Finally, Part VI suggests that Korea should continue to create and modify laws and policies that protect the rights of children to live free from abuse, eliminate statutory provisions that discriminate based on lineal heritage, and allow courts to consider BCS evidence in child abuse prosecutions, self-defense claims, and as a mitigating factor in sentencing.

Wesley’s Educational Ideal at Kingswood and the Modern Christian School

James Riley Estep 한국기독교교육정보학회 2008 Journal of Christian education information tech Vol.0 No.14

Wesley was indeed an educational philosopher and innovator. His philosophy of education is readily documented in his Journals and Sermons. However, his philosophy of education is embodied in the Kingswood School established by Wesley himself near the town of Bristol in England. This article not only chronicles the establishment and formation of the Kingswood school, but extrapolates lessons from its legacy for modern Christian schools.
