Opportunistic Media Access for Multirate Ad Hoc Networks

by B. Sadeghi, V. Kanodia, A. Sabharwal, E. Knightly , 2002
"... The IEEE 802.11 wireless media access standard supports multiple data rates at the physical layer. Moreover, various auto rate adaptation mechanisms at the medium access layer have been proposed to utilize this multi-rate capability by automatically adapting the transmission rate to best match the c ..."

for the same time-shares as achieved by single-rate IEEE 802.11. We describe mechanisms to implement OAR on top of any existing auto-rate adaptation scheme in a nearly IEEE 802.11 compliant manner. We also analytically study OAR and characterize the gains in throughput as a function of the channel conditions

SSCH: Slotted Seeded Channel Hopping for Capacity Improvement in IEEE 802.11 Ad-Hoc Wireless Networks

by Paramvir Bahl, Ranveer Chandra - in IEEE 802.11 Ad-Hoc Wireless Networks,” in ACM Mobicom , 2004
"... Capacity improvement is one of the principal challenges in wireless networking. We present a link-layer protocol called Slotted Seeded Channel Hopping, or SSCH, that increases the capacity of an IEEE 802.11 network by utilizing frequency diversity. SSCH can be implemented in software over an IEEE 80 ..."

802.11-compliant wireless card. Each node using SSCH switches across channels in such a manner that nodes desiring to communicate overlap, while disjoint communications mostly do not overlap, and hence do not interfere with each other. To achieve this, SSCH uses a novel scheme for distributed

Active compliant motion: a survey

by Tine Lefebvre, Jing Xiao, Herman Bruyninckx, Gudrun De Gersem , 2005
"... Whether they are asked to polish or assemble parts, clean the house or open doors, the future generation of robots will have to cope with contact tasks under uncertainty in a stable and safe manner. Obtaining a controlled contact motion under uncertainty is still a major challenge for the robotics ..."

Self-Adaptive Compliant Persistent Architectures

by Francis Vaughan, Dave Munro
"... Systems that can dynamically adapt their operating parameters to changing conditions are increasingly needed, especially for long-lived or large applications. Current selfadaptive algorithms tend to be directed at particular optimisations and rarely operate in concert with other optimisations. The s ..."
Abstract - Add to MetaCart
. The static nature of conventional systems design is not conducive to adaptation. Further, the poor structure and uncoordinated manner in which individual optimisations are incorporated leads to unconstrained complexity of operation. Such lack of structure can lead to poorer than expected or pathological

Value Preservation Through Risk Management. A Shariah Compliant Proposal For Equity Risk Management

by Obiyathulla I. Bacha, Obiyathulla Ismath Bacha
"... This paper makes a case for the preservation of Muslim Wealth through risk management. It provides an exposition of risk management techniques used in conventional finance and outlines the limitations faced by Muslim fund managers and businesses. This limitation arises from the proscription of key r ..."

with On Balance Sheet methods is that they require the restructuring of business transactions which can render businesses less competitive and subject to residual risk. The paper proposes a portfolio insurance scheme that uses the logic and mechanics of conventional Index Put Options but in a Shariah compliant

A CORBA Compliant Transactional Workflow System for Internet Applications

by S. M. Wheater, S. K. Shrivastava, F. Ranno - IFIP INTERNATIONAL CONFERENCE ON DISTRIBUTED SYSTEMS PLATFORMS AND OPEN DISTRIBUTED PROCESSING (MIDDLEWARE'98), THE LAKE DISTRICT , 1998
"... The paper describes an application composition and execution environment implemented as a transactional workflow system that enables sets of inter-related tasks to be carried out and supervised in a dependable manner. The paper describes how the system meets the requirements of interoperability, sca ..."

AN INSTANT CENTER APPROACH TO THE CONCEPTUAL DESIGN OF COMPLIANT MECHANISMS

by Charles J. Kim, Sridhar Kota, Yong-mo Moon
"... The conceptual design of compliant mechanisms is generally performed using one of two methods: topology optimization or the Pseudo-Rigid-Body Model. In this paper, we present a conceptual design methodology which utilizes a building block approach. The concept of the instant center is developed for ..."

HANIME An H-Anim Compliant Avatar Editor for NVEs

by Christos Bouras, K. Kartsakalis, V. Triglianos, Th. Tsiatsos
"... This paper addresses the problem of a visual H-Anim avatar editor. Although H-Anim is a very promising standard for interchangeable avatars and avatar’s animation, the lack of an effective yet simple to use visual avatar editor could repel users from H-Anim compliant Networked Virtual Environments. ..."
Abstract - Add to MetaCart
. Therefore this paper presents an H-Anim compliant editor, called HanimE, for creating avatars for Networked Virtual Environments. This editor is entirely based on a graphical user interface and allows users to customize H-Anim avatars, in a simple yet effective manner. The avatars created by HanimE can
