Adaptive Voip Playout Scheduling: Assessing User Satisfaction, Miroslaw Narbutt, Andrew Kelly, Liam Murphy, Philip Perry

Articles

Delay and packet loss dramatically affect the quality of a voice-over-IP (VoIP) call and depend on the playout buffer scheme implemented at the receiver. The choice of playout algorithm can’t be based on statistical metrics without considering the perceived end-to-end conversational speech quality. The authors present a method for evaluating various playout algorithms that extends the Emodel concept by estimating user satisfaction from time-varying transmission impairments. This article evaluates several playout algorithms and shows a correspondence between their results and those obtained via statistical loss and delay metrics.

Cavity-Backed Slot Antenna Array For The Repeater System Of A Satellite Digital Multimedia Broadcasting Service, Byungje Lee, Frances J. Harackiewicz, Byungwoon Jung, Myun-Joo Park

Articles

For the repeater system of the satellite digital multimedia broadcasting (DMB) service (2630~2655 MHz) requiring a high-gain antenna and enough isolation between antennas, a cavity-backed slot antenna array (CBSAA) fed by a single waveguide is proposed to suppress side lobe level (SLL) and to increase front-to-back ratio (FBR). The SLL and FBR are enhanced with an optimized magnitude ratio of the electric field at each slot and an additional vertical reflector. The measured SLLs in the Hand E-planes are under -33.24 and -35.78 dB, respectively. An FBR over 37.84 dB and a peak gain over 17 dBi are measured. The …

The Problem Of New Uses, Rebecca S. Eisenberg

Articles

Discovering new uses for drugs that are already on the market seems like it ought to be the low-lying fruit of biopharmaceutical research and development (R&D). Firms have already made significant investments in developing these drugs and bringing them to market, including testing them in clinical trials, shepherding them through the FDA regulatory approval process, building production facilities, and training sales staff to market them to physicians. By this point, the drugs have begun to enjoy goodwill among patients and physicians and casual observations in the course of clinical experience may point to potential new uses. One might expect that …

What Counts As Fraud? An Empirical Study Of Motions To Dismiss Under The Private Securities Litigation Reform Act, Adam C. Pritchard, Hillary A. Sale

Articles

This article presents the findings of a study of the resolution of motions to dismiss securities fraud lawsuits since the passage of the Private Securities Litigation Reform Act (PSLRA) in 1995. Our sample consists of decisions on motions to dismiss in securities class actions by district and appellate courts in the Second and Ninth Circuits for cases filed after the passage of the Reform Act to the end of 2002. These circuits are the leading circuits for the filing of securities class actions and are generally recognized as representing two ends of the securities class action spectrum. Post-PSLRA, the Second …

Telling Stories About Health Insurance: Using New Films In The Classroom, Elizabeth Pendo

Articles

In keeping with the theme of "The Mass Media's Influence on Health Law and Policy," this essay is designed to share my experience using clips from three recent popular films as a method of enhancing coverage and discussion of legal and policy issues surrounding the private health insurance system, and to provide some practical advice for others interested in doing the same. It builds upon a presentation that I gave along with Professors Timothy S. Hall and Ross D. Silverman at the 2004 Health Law Teachers Conference entitled "Health Law, Policy and Media," and was inspired by Professor Paul Bergman's …

Prometheus Radio Project V. Fcc: The Persistence Of Scarcity, Aaron Perzanowski

Articles

Part I traces the history of broadcast regulation, emphasizing the development of the scarcity doctrine and the subsequent deregulatory trend. Part II examines the FCC's 2003 rule changes and the Third Circuit's analysis of those modifications in Prometheus Radio Project v. FCC. Part III analyzes the assumptions underlying the FCC's proffered explanation for its rule changes, ultimately concluding that they lack justification, and offers suggestions for responsible ownership deregulation. Part IV calls on Congress to reassert itself as the final arbiter of media policy.

Regulation Of Companies With Publicly Listed Share Capital In The People's Republic Of China, Nicholas C. Howson

Articles

Mr. Chairman, colleagues, and friends: It is a great honor for me to be able to address this group of experts and legislators, and many colleagues and friends, on a topic I care deeply about-the regulation of so-called public companies, both outside of China and, since the early 1990s, inside of China. First, and with many of the others invited to participate in this conference today and tomorrow, I thank the Office of Legislative Affairs ("OLA") of the State Council of the People's Republic of China ("PRC") as well as the China Securities Regulatory Commission ("CSRC") for convening this very …

Schiavo And Klein (Symposium), Evan H. Caminker

Articles

When teaching federal courts, I sometimes find that students are slow to care about legal issues that initially seem picayune, hyper-technical, and unrelated to real-world concerns. It takes hard work to engage students in discussion of United States v. Klein,1 notwithstanding its apparent articulation of a foundational separation of powers principle that Congress may not dictate a "rule of decision" governing a case in federal court. A Civil War-era decision about the distribution of war spoils, one the Supreme Court has hardly ever cited since and then only to distinguish it, in cases involving takings and spotted owls? Yawn.

The Invariant Algorithm For Identification And Detection Of Multiple Gas Plumes And Weak Releases, Erin O'Donnell, David W. Messinger, Carl Salvaggio, John Schott

Articles

The ability to detect and identify gaseous effluents is a problem that has been pursued with limited success. It has been shown to bepossible using the Invariant algorithm on synthetic hyperspectralscenes with a strong single gas release. That however, is a veryspecific case and leaves room for further investigation. This studylooks at more realistic detection and release scenarios. Ourimplementation of the Invariant algorithm uses Singular ValueDecomposition (SVD) to select basis vectors from a subspace of targetgases in conjunction with a Generalized Likelihood Ratio Test (GLRT) to determine on a pixel by pixel basis how ``like" the target gas each pixel …

Spectral Imaging Using A Commercial Colour-Filter Array Digital Camera, Roy Berns, Lawrence Taplin, Mahdi Nezamabadi

Articles

A multi-year research programme is underway to develop and deliver spectral-based digital cameras for imaging cultural heritage at the National Gallery of Art, Washington DC, and the Museum of Modern Art, New York. The cameras will be used for documentation, production imaging, and conservation science. Three approaches have undergone testing: a liquid-crystal tunable filter (LCTF) coupled with a monochrome camera, a six-position filter wheel containing absorption filters coupled with a monochrome camera, and a two-position filter slider containing absorption filters coupled with a colour-filter array (CFA) colour camera. The last approach is the most practical as it uses conventional digital …

Evaluation Of A Modified Sinar 54m Digital Camera At The National Gallery Of Art, Washington Dc During April, 2005, Roy Berns, Lawrence Taplin

Articles

On April 26 – 27 2005, the RIT team brought their prototype Sinar 54M camera system to the National Gallery of Art’s Imaging Department. The team included Lawrence Taplin, Mitchell Rosen, and Roy Berns. RIT brought a spectroradiometer to measure the daylight fluorescent viewing illumination and if time allowed, NGA’s CRT display. They also brought a Macintosh G5 to control the camera and for image processing. NGA is using a production Sinar 54M. This enabled a direct comparison between NGA’s digital imaging workflow and the RIT workflow. Both cameras used the same lighting, Broncolor pulsed Xenon, lighting geometry, and photography …

Solving An Mri Spin Relaxometry Problem With Parallel Computing, Alan Kaminsky, Luke Mcomber

Articles

MRI spin relaxometry is the process of recovering the spin density spectrum from the time samples of the spin signal for each pixel of a magnetic resonance image. Since healthy tissue exhibits different spin relaxation rates from diseased tissue, MRI spin relaxometry potentially has utility for diagnosing disease. However, recovering the spin relaxation rates involves solving an inverse problem which requires substantial computation. The computation's running time can be reduced by processing the pixels in parallel on a parallel computer. A parallel program for solving the MRI spin relaxometry problem, SRSolve, was implemented in Java with MPI, its running time …

A Search For Molecular Gas In Ghz-Peaked Spectrum Radio Sources, Christopher P. O'Dea, Jack Gallimore, Carlo Stanghellini, Stefi A. Baum, James M. Jackson

Articles

We present searches for molecular gas (CO, OH, CS, and NH3) in six GHz Peaked Spectrum (GPS) radio sources. We do not detect gas in any source and place upper limits on the mass of molecular gas which are generally in the range ~10^9 to a few times 10^10 M⊙. These limits are consistent with the following interpretations: (1) GPS sources do not require very dense gas in their hosts, & (2) The GPS sources are unlikely to be confined by dense gas and will evolve to become larger radio sources (Refer to PDF file for exact formulas).

Geometric Modeling Of Engineered Abrasive Processes, Andres L. Carrano, James B. Taylor

Articles

One of the common issues that arises in abrasive machining is the inconsistency of the surface roughness within the same batch and under identical machining conditions. Recent advances in engineered abrasives have allowed replacement of the random arrangement of minerals on conventional belts with precisely shaped structures uniformly cast directly onto a backing material. This allows for abrasive belts that are more deterministic in shape, size, distribution, orientation, and composition. A computer model based on known tooling geometry was developed to approximate the asymptotic surface profile that was achievable under specific loading conditions. Outputs included the theoretical surface parameters, R^sub …

Simple Light Slave Synchronizers, Andrew Davidhazy

Articles

The subject of setting off a flash in response to the light of another one is a problem that comes up from time to time in photographic situations. Here is a non-electronic description of how one might make "slave syncs" from scratch and whether they work or not hopefully have some fun in the process.

Breaking The Exposure Time Barrier!, Andrew Davidhazy

Most of the time there is a desire to make photographs of action events that do not exhibit any motion blur. But blur can be a beautiful thing and this brief article extolls the virtues of braking the sharpness convention

String Vibrations, Andrew Davidhazy

Articles

A little "fib" led to a photographic investigation of vibrating strings to be used as an illustration to go along with an article on the "String Theory". Again, proving that not all photographs need to be sharp to be effective.

Stressed Plastics By Polarization, Andrew Davidhazy

Articles

Many transparent objects, especially those made of plastic, although other materials behave similarly, change the character of an incident beam of light in a manner that is hardly visible to the naked eye. However, this property of can be used to produce some truly spectacular visual results.

The Impact Of Cultural Diversity On Web Site Design, Jack Cook, Mike Finlayson

Articles

Close your eyes. Envision a succulent two-inch slab of dripping-rare prime rib. Is your stomach rumbling, your appetite peaked, or are you offended since your fundamental belief system precludes harming animals? A single image or idea can create many diferent feelings or interpretations. Consider the diversity within your own organization, campus, or community. Does everyone agree on what is appropriate, acceptable, appetizing, or attractive? An image pleasing to one group of people may alienate or even seriously offend many others. Something as simple as color may elicit dramatically different mental images. For example, in the U.S., white is generally associated …

Converged Vs. Dedicated Ipsec Encryption Testing In Gigabit Ethernet Networks, Luther Troell, Jason Burns, Kurt Chapman, Dave Goddard, Matt Soderlund, Chris Ward

Articles

In January, 2005, Safenet, Inc. contacted the networking group to investigate the possibility of using our students for the purpose of comparing the performance of dedicated encryption device to an integrated encrypting device. The tests would also include a performance comparison between Data Link Layer (Layer 2) devices and Network Layer (Layer 3) devices. It was decided that the tests would consist of throughput, frame loss, and network latency. Two network topologies were used for the experiments: gigabit Ethernet and SONET OC-48. The equipment to be tested was Safenet’s High Assurance 4000 Gateway (HA4000) for the gigabit Ethernet topology and …

Cultural Studies At R.I.T./U.S.A: Of Visual Culture And Pedagogical Interventions, Amit Ray

Articles

Abstract:

This paper examines the role of Cultural Studies in addressing the limitations of American visual culture through pedagogical interventions at Rochester Institute of Technology. Ray argues that despite globalization's potential to enhance international understanding, American visual media remains largely ethnocentric and resistant to representing the complex realities of global interconnectedness. Using the recent Iraq War as an example, he demonstrates how media coverage systematically obscured cultural, historical, and linguistic contexts while promoting martial nationalism. The author proposes using popular animated television programs like The Simpsons and South Park as pedagogical tools to expose the contradictory nature of contemporary media …

The Pitfalls Of International Integration: A Comment On The Bush Proposal And Its Aftermath, Reuven S. Avi-Yonah

Articles

In January 2003, the Bush Administration proposed a new system for taxing corporate dividends, under which domestic shareholders in U.S. corporations would not be taxed on dividends they received, provided the corporation distributed these dividends out of after-tax earnings (the “Bush Proposal”). The Bush Proposal was introduced in Congress on February 27, 2003. Ultimately, however, Congress balked at enacting full-?edged dividend exemption. Instead, in the Jobs and Growth Tax Relief Reconciliation Act of 2003 (“JGTRRA”) as enacted on May 28, 2003, a lower rate of 15% was adopted for dividends paid by domestic and certain foreign corporations,1 and the capital …

Holding Intellectual Property, Xuan-Thao Nguyen

Articles

The collapse of WorldCom, Inc., exposed a complex web of accounting irregularities. Within that web, recent filings by Dick Thornburgh, WorldCom's Bankruptcy Court Examiner, reveal a different type of scheme that involves the holding of intellectual property. Further scrutinizing the scheme reveals that WorldCom and its tax advisors, KPMG Peat Marwick LLP (KPMG), devised a tax avoidance scheme through the creation of an intellectual property holding company (IP holding company). This type of scheme has been widely and quietly utilized in the last twenty years by many corporations with substantial intellectual property.

Indeed, as state taxing authorities have become more …
