Deterministic Time-Varying Packet Fair Queueing for Integrated Services Networks
- IN IEEE GLOBAL TELECOMMUNICATIONS CONFERENCE, 2000
, 2002
"... In integrated services networks, the provision of Quality of Service (QoS) guarantees depends critically upon the scheduling algorithm employed at the network layer. In this work we review fundamental results on scheduling, and we focus on Packet Fair Queueing (PFQ) algorithms, which have been propo ..."

proposed for QoS wirelinewireless networking. The basic notion in PFQ is that the bandwidth allocated to a session is proportional to a positive weight # i . Because of the fixed weight assignment, the inherent in PFQ delay-bandwidth coupling imposes limitations on the range of QoS that can be supported
Scalar speed limits and cosmology: Acceleration from D- cceleration
- Phys. Rev. D70 (2004) 103505, hep-th/0310221
"... Causality on the gravity side of the AdS/CFT correspondence restricts motion on the moduli space of the N = 4 super Yang Mills theory by imposing a speed limit on how fast the scalar field may roll. This effect can be traced to higher derivative operators arising from integrating out light degrees o ..."

Filling-in by joint interpolation of vector fields and gray levels
- IEEE TRANS. IMAGE PROCESSING
, 2001
"... A variational approach for filling-in regions of missing data in digital images is introduced in this paper. The approach is based on joint interpolation of the image gray-levels and gradient/isophotes directions, smoothly extending in an automatic fashion the isophote lines into the holes of missi ..."

No limitations are imposed on the topology of the holes, and all regions of missing data can be simultaneously processed, even if they are surrounded by completely different structures. Applications of this technique include the restoration
Classification of Multiple Cancer Types by Multicategory Support Vector Machines Using Gene Expression Data
- JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION
, 2002
"... Monitoring gene expression profiles is a novel approach in cancer diagnosis. Several studies showed that prediction of cancer types using gene expression data is promising and very informative. The Support Vector Machine (SVM) is one of the classification methods successfully applied to the cancer d ..."

In this paper, we analyze a couple of published multiple cancer types data sets by the multicategory SVM, which
Panel Data Models with Interactive Fixed Effects
, 2005
"... This paper considers large N and large T panel data models with unobservable multiple interactive effects. These models are useful for both micro and macro econometric modelings. In earnings studies, for example, workers ’ motivation, persistence, and diligence combined to influence the earnings in ..."

We also derive the constrained estimator and its limiting distribution, imposing additivity coupled with interactive effects. The problem of testing additive versus interactive effects
Virtual Wires: Overcoming Pin Limitations in FPGA-based Logic Emulators
"... Existing FPGA-based logic emulators suffer from limited inter-chip communication bandwidth, resulting in low gate utilization (10 to 20 percent). This resource imbalance increases the number of chips needed to emulate a particular logic design and thereby decreases emulation speed, since signals mus ..."

. Virtual wires not only increase usable bandwidth, but also relax the absolute limits imposed on gate utilization. The resulting improvement in bandwidth reduces the need for global interconnect, allowing effective use of low dimension inter-chip connections (such as nearest-neighbor). Nearest
NIST Net: A Linux-based Network Emulation Tool
- Computer Communication Review

Testing of network protocols and distributed applications has become increasingly complex, as the diversity of networks and underlying technologies increase, and the adaptive behavior of applications becomes more sophisticated. In this paper, we present NIST Net, a tool to facilitate testing and exp ..."

NIST Net enables experimenters to model and effect arbitrary performance dynamics (packet delay, jitter, bandwidth limitations, congestion, packet loss and duplication) on live IP packets passing through a commodity Linux-based PC router. We describe
Materials for an exploratory theory of the network society.

The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

AIP, to be published A Fundamental Limit of Measurement Imposed by the Elementary Interactions

Among many possible limits of quantum measurement, the simplest ones were derived directly from the uncertainty principles. However, s ..."
