Distributed Communication Architecture for Smart Grid Applications

One big challenge in building a smart grid arises from the fast growing amount of data and limited communication resources. The traditional centralized communication architecture does not scale well with the explosive increase of data and has a high probability of encountering communication bottlenecks due to long communication paths. To address this challenging issue, this article presents a distributed communication architecture that implements smart grid communications in an efficient and cost-effective way. This distributed architecture consists of multiple distributed operation centers, each of which is connected to several data concentrators serving one local area and only sends summary or required integrated information to a central operation center. Using this distributed architecture, communication distance is much shortened, and thus data will be delivered more efficiently and reliably. In addition, such a distributed architecture can manage and analyze data locally, rather than backhauling all raw data to the central operation center, leading to reduced cost and burden on communication resources. Advanced metering infrastructure is chosen as an example to demonstrate benefits of this architecture on improving communication performance. The distributed communication architecture is also readily applicable to other smart grid applications, for example, demand response management systems

Understanding Consumers’ Avoidance of Personalized Advertising in Social Commerce: The Leveraging Effect of Information Transparency and Information Dissemination Scenes

With the growing proliferation of personalized advertising during the process of browsing information in social commerce platform, consumers’ advertising avoidance has made a potential challenge to the advertising push of platform managers. However, the research currently lacks an understanding of how advertising avoidance can be related to consumer perception and information dissemination. Based on rational choice theory (RCT), this study investigates the mediating role of perceived advertising relevance and perceived vulnerability for advertising avoidance, especially adding the variables of information transparency and information dissemination scene to explore the interacting effect between information dissemination and advertising matching. An online experiment was conducted to empirically test the conceptual model and the result indicated the positive effect of perceived vulnerability and the negative effect of perceived advertising relevance on advertising avoidance. Besides, higher information transparency will lead to more consumer\u27s perceived relevance to advertising, and when the same advertisement is displayed on social web pages, the perceived vulnerability will turn higher. This study provides theoretical implications and practical guidance for online advertising research and practices, especially on leveraging and managing information dissemination of personalized advertising on social commerce platform

Value Creation of E-commerce Platform Firms in Competitive Dynamics: From a Resource Orchestration Perspective

This study examines the rules of resource combination for e-commerce platform firms value creation in competitive dynamics. Based on the resource orchestration view and competitive dynamics theory, we suggest a configurational analytic framework that departs from the standard linear paradigm to examine how configurations of digital strategic action formed by digital resources creates value through the effect that competitors hard to respond to. In line with this approach, we use fuzzy-set qualitative comparative analysis (fsQCA) to news data from Chinese online tourism industry. Our findings suggest equifinal pathways to gain the effect that is hard to be responded and the specific boundary conditions of our propositions that determine what way digital technologies and partnership resources orchestrate in e-commerce platform firms’ creating value. We discuss implications for theory and practice

Corporate Social Responsibility: a Constitutional Perspective

Originally, the concept of CSR was come from business ethic values that impose corporation\u27s ethical responsibly to their social and natural environment. That development of ethical business was part of social consciousness on the degradation of environment as impact of corporation activities. This reality also raised the deep environmental ethic or deep ecology which challenge anthropocentrism economical development and urged ecocentrism development. In Indonesia, this phenomenon was marked by the enactment of Act 4/1982 on Environmental Management.The constitutional debate on CSR just began when the Indonesian Constitutional Court heard and decided the judicial review case of Act 40/2007 on Limited Liability Company which stipulate CSR mandatory law for corporation that have activity in natural resources areas. In its decision, Constitutional Court refused the petition. This means that the court affirmed that CSR mandatory law is not contrary to the Constitution. However, the legal argumentation of the court was not shifted from economical and environmental perspectives. The constitutional basis of the decision is Article 33 (4) concerning national economic principles and Article 33 (3) concerning state power on land, water, and natural resources. The Constitutional Court did not use the human rights concept as the source of CSR mandatory law.In constitutional law perspective, we can justify the CSR mandatory law from human rights guarantee on the constitution. CSR is one of the obligations to respect, to protect, to fulfill, and to promote human rights. Those obligations are not only bind over the government, but also corporation and all citizens. In that perspective, CSR should be mandatory law not only for the corporation which manage or correlate with natural resource, but for all corporations that operate in the middle of the society

Multiphase Flow Packed-Bed Reactor Modeling: Combining CFD and Cell Network Model

The Performance of a Multiphase Flow Packed-Bed Reactor Was Evaluated by a Mixing-Cell Network Model in Which the Cell-Scale Flow Field Information Was Provided by Multifluid CFD Modeling. Such a Sequentially Combined Modeling Approach Was Able to Show the Heterogeneity of Liquid Species Conversion in a Trickle-Bed Reactor that Has Been Confirmed by in Situ Magnetic Resonance Experiments. 1 a Conventional Plug Flow Model (PFM) and Axial Dispersion Model (ADM) Showed Either overpredicted or Underpredicted Conversion Compared with the Conversion Computed from the CFD-Cell Network Model. Preliminary Case Study Has Shown the Ability of the CFD-Cell Network Model in Assessing the Impact of Flow Distribution on the Trickle-Bed Reactor Performance, which is a Great Help to Trickle-Bed Reactor Design and Diagnosis. © 2005 American Chemical Society

Modeling of Trickle-Bed Reactors with Exothermic Reactions using Cell Network Approach

One-Dimensional (1D) and Two-Dimensional (2D) Cell Network Models Were Developed to Simulate the Steady-State Behavior of Trickle-Bed Reactors Employed for the Highly Exothermic Hydrotreating of Benzene. the Multiphase Mass Transfer-Reaction Model and Novel Solution Method Are Discussed in This Report. the 1D Model Was Shown to Satisfactorily Simulate the Axial Temperature Field Observed Experimentally for Multiphase Flow with Exothermic Reactions. the 2D Reactor Modeling Provided Valuable Information About Local Hot Spot Behavior within the Multiphase Reactor, Identifying Situations in Which Hot Spots May Form. the Model Took into Consideration the Heterogeneous Nature of Liquid Distribution, Including Radial Liquid Maldistribution and Partial External Wetting. This Approach Was Proven to Be Stable and Efficient in Dealing with the Complex Interaction of Phase Vaporization and Temperature Rise. through Analysis and Discussion, This Report Established the Cell Network Model as a Valid Representation of the Flow Environment Produced in a Trickle Bed with Exothermic Reactions. © 2007 Elsevier Ltd.
