Whitepaper: A Dynamic Assessment Of VoIP Adoption, Innovation And Their Interaction With CALEA Regulation

by Massachusetts Institute of TechnologyJan 01, 2008

This research paper present a system dynamics model to understand the complex feedback system surrounding VoIP adoption, innovation and the current VoIP CALEA proceedings. System dynamics is a methodology for studying and managing complex feedback systems using a computer simulation. The adoption of the ""managed"" and ""unmanaged"" VoIP is modeled to understand the fraction of VoIP that will be under the CALEA jurisdiction. The paper then models the cost of compliance for the providers of the


Whitepaper: Measuring Value and Productivity of Information Technology Using a Process-Based Approach: The Case for RFID Technology

by Massachusetts Institute of TechnologyJan 01, 2008

The application of RFID to the consumer packaged goods (CPG) supply chain has been one of the first to capture large scale adoption. This paper presents one of the first attempts to create a systematic methodology to assess the impact of IT in business process performance metrics. It presents preliminary results on how to use such methodology to analyze the impact of a given IT technology, namely RFID (Radio Frequency Identification Devices), in performance metrics of a consumer packaged goods


Whitepaper: MapJAX: Data Structure Abstractions for Asynchronous Web Applications

by Massachusetts Institute of TechnologyJan 01, 2008

MapJAX provides the abstraction of data structures shared between the browser and the server, based on the familiar primitives of objects, locks, and threads. This research paper from Massachusetts Institute of Technology describes the design and implementation of the MapJAX framework and show its use in three prototypical web applications: a mapping application, an email client, and a search-autocomplete application.


Whitepaper: The Neutral Internet: An Information Architecture For Open Societies

by Massachusetts Institute of TechnologyJan 01, 2008

This research paper published by Massachusetts Institute of Technology describes that Internet and the World Wide Web have emerged as unprecedented open platforms for speech and innovation. Now, there is a raging debate about how to ensure that the Internet remains open, accessible and innovative, while at the same time, encourage deployment of new broadband network. This paper argues that it is possible to preserve the neutral, nondiscriminatory essence of the Internet, without sacrificing


Whitepaper: Measured Data Rate From Adaptive Modulation in Wideband OFDM Systems

by Massachusetts Institute of TechnologyJan 01, 2008

Adaptive modulation is implemented on a wideband OFDM transceiver prototype to quantify its performance in indoor wireless environment. The measurements indicate that over a bandwidth of 100 MHz, the channel varies quite significantly. With a target uncoded Bit Error Rate of 10?3, it is found that at link distances of 1.0 to 10.8 meters, the data rate varies from 395 Mbps to 76 Mbps. The measured adaptive average data rate is 2.88 times the average data rate without adaptive modulation.


Whitepaper: The Power Line Transmission Characteristics for an OFDM Signal

by Massachusetts Institute of TechnologyJan 01, 2008

This research paper measures what influence the sinusoidal transmission characteristics of the electric power line with various forms gave to the transmission characteristic of OFDM (Orthogonal Frequency Division Multiplexing) signal through PLC (Power Line Communication system) modem. The electric power line transmission line with various forms in a real environment is classified into two basic elements, which are an outlet type branch and a switch type branch. Next, PHY rate (Physical rate) is


Whitepaper: Offshoring Radiology Services To India

by Massachusetts Institute of TechnologyJan 01, 2008

This research paper discusses teleradiology and medical image reconstruction from the perspectives of both India and its client countries. Radiology is an ""Extreme"" professional service with extensive usage of tacit rather than codified knowledge. The importance of tacit knowledge leads to long training periods, a limited global supply of radiologists and heavy government regulation, all of which are obstacles to a ""Flat world"". Computerization of low-end diagnostic radiology ultimately


Whitepaper: Peer Effects And Entrepreneurship

by Massachusetts Institute of TechnologyJan 01, 2008

This research paper from Massachusetts Institute of Technology directly test the hypothesis that an individual’s colleagues might impact their transition to entrepreneurship, by looking at how diversity in the prior career histories of an individual’s peers relates to their own propensity to become an entrepreneur. They found that employees are more likely to become entrepreneurs if their co-workers have had prior self-employment experience or have had more diverse work experience in


Whitepaper: The Outsourcing And Off-shoring Competitive Landscape And Its Uncertainties

by Massachusetts Institute of TechnologyJan 01, 2008

Outsourcing refers to the practice during which a company subcontracts a business function to an outside supplier. Outsourcing providers are pressured to increase the value delivered to clients. This paper discusses the different categories of vendors or ESP’s, and their concerns. First, the difference between offshore providers and onshore providers is discussed. After that, the difference between low-end and high-end services is explained. These two aspects, serve as a description of the


Whitepaper: Amodel Of Final-Offer Arbitration In Regulation

by Massachusetts Institute of TechnologyJan 01, 2008

Regulatory process in which both the regulator and the regulated firm propose prices that, in case of disagreement, are settled through final-offer arbitration - a practice currently used in Chile for setting prices in the water sector. Rather than submitting a single offer, each party simultaneously submits an offer for each of the firm’s cost units (e.g., cost of raw water, capital cost). While a multiple-offers scheme allows the arbitrator to better approximate her ideal settlement, it
