Low-Latency Broadcast In Multirate Wireless Mesh Networks, Chun Tung Chou, Archan Misra, Junaid Qadir

Research Collection School Of Computing and Information Systems

In a multirate wireless network, a node can dynamically adjust its link transmission rate by switching between different modulation schemes. In the current IEEE802.11a/b/g standards, this rate adjustment is defined for unicast traffic only. In this paper, we consider a wireless mesh network (WMN), where a node can dynamically adjust its link-layer multicast rates to its neighbors, and address the problem of realizing low-latency network-wide broadcast in such a mesh. We first show that the multirate broadcast problem is significantly different from the single-rate case. We will then present an algorithm for achieving low-latency broadcast in a multirate mesh which …

Detection And Identification Of Vehicles Based On Their Unintended Electromagnetic Emissions, Xiaopeng Dong, Haixiao Weng, Daryl G. Beetner, Todd H. Hubing, Donald C. Wunsch, Michael Noll, Huseyin Goksu, Benjamin Moss

Electrical and Computer Engineering Faculty Research & Creative Works

When running, vehicles with internal combustion engines radiate electromagnetic emissions that are characteristic of the vehicle. Emissions depend on the electronics, harness wiring, body type, and many other features. Since emissions are unique to each vehicle, these may be used for identification purposes. This paper investigates a procedure for detecting and identifying vehicles based on their RF emissions. Parameters like the average magnitude or standard deviation of magnitude within a frequency band were extracted from measured emission data. These parameters were used as inputs to an artificial neural network (ANN) that was trained to identify the vehicle that produced the …

Dynamic Programming-Based Energy-Efficient Rate Adaptation For Wireless Ad Hoc Networks, Maciej Jan Zawodniok, Jagannathan Sarangapani

Electrical and Computer Engineering Faculty Research & Creative Works

Resource constraints require that ad hoc wireless networks are energy efficient during transmission and rate adaptation. In this paper we propose a novel cross-layer energy-efficient rate adaptation scheme that employs dynamic programming (DP) principle to analytically select the modulation scheme online. The scheme uses channel state information from the physical layer and congestion information from the scheduling layer to select a modulation rate. This online selection maximizes throughput while saving energy and preventing congestion. The simulation results indicate that an increase in throughput by 96% and energy-efficiency by 131% is observed when compared to the Receiver Based AutoRate (RBAR) protocol.

Weak-Group Unitary Space-Time Codes, Adam Panagos, Kurt Louis Kosbar, Asif Iqbal Mohammad

Electrical and Computer Engineering Faculty Research & Creative Works

We propose a construction technique for unitary space-time codes that use Givens rotation matrices. These constellations have a desirable weak group property that leads to reduced construction and decoding complexity. The newly constructed constellations have the best known diversity product and diversity sum for a wide range of constellation sizes and number of transmit antennas.

An M/M/1 Retrial Queue With Unreliable Server, Nathan P. Sherman, Jeffrey P. Kharoufeh

Faculty Publications

We analyze an unreliable M/M/1 retrial queue with infinite-capacity orbit and normal queue. Retrial customers do not rejoin the normal queue but repeatedly attempt to access the server at i.i.d. intervals until it is found functioning and idle. We provide stability conditions as well as several stochastic decomposability results.

The Ninth Amendment: It Means What It Says, Randy E. Barnett

Georgetown Law Faculty Publications and Other Works

Although the Ninth Amendment appears on its face to protect unenumerated individual rights of the same sort as those that were enumerated in the Bill of Rights, courts and scholars have long deprived it of any relevance to constitutional adjudication. With the growing interest in originalist methods of interpretation since the 1980s, however, this situation has changed. In the past twenty years, five originalist models of the Ninth Amendment have been propounded by scholars: The state law rights model, the residual rights model, the individual natural rights model, the collective rights model, and the federalism model. This article examines thirteen …

It also includes a timeline and generalized description of the immediate effect of Hurricane Katrina on the city, and the flood resulting from the failure of the federal levee system protecting Greater New Orleans.

Pathophysiology Of Cerebral Venous Thrombosis--An Overview., Ahmed Itrat, Sana Shoukat, Ayeesha Kamran Kamal

Department of Medicine

Cerebral venous sinus thrombosis is a disorder with a unique pathophysiology which needs to be described. A Medline search of all articles detailing pathophysiology of CVST was done, using keywords: cerebral venous thrombosis and pathophysiology. In addition, major texts were reviewed for additional references. The pathophysiology of CVST depends on two interconnected events, local signs due to venous infarct, e.g., hemiparesis and global signs due to raised ICP from an obstructed venous system--papilloedema and isolated intracranial hypertension being one of them. Pathophysiology of CVST is diverse and makes it easier to understand the diversity of clinical presentations.

Role Of Surgery In Cerebral Venous Sinus Thrombosis, S. Ather Enam

Department of Surgery Docs

Cerebral venous sinus thrombosis (CVST) usually is taken care of by medical management or neuro-interventional vascular techniques. Some cases of CVST may take a malignant course if the intracranial pressure increases excessively. This increase in pressure is because of oedema in brain tissue due to impediment in venous return and/or intracerebral haemorrhage. Neurosurgical experience has shown remarkable recovery in these moribund patients if appropriate surgical intervention is done within reasonable time. Emergent decompressive craniotomy or other neurosurgical interventions are the only appropriate treatment in these malignant forms of CVST to prevent mortality and severe morbidity.

Development Plan For The Energy Sector 2007 - 2017, Bureau Des Mines Et De L'Energie

Latin American Energy Dialogue, White Papers and Reports

The national program for the development of the energy sector of Haiti seeks to enable policy makers and various stakeholders providing them with a management tool for the industry. The program covers the period 2007-2032. The conservation of natural resources (especially forests) from the point of view of energy management and environmental integrity will be considered through various measures such as: Support for more efficient use of fuel from wood and charcoal; the production of energy and other forest biomass resources; the conversion to diesel, bio-diesel and LPG of 1,000 small businesses that use wood as fuel; the promotion of …

Three Strategically Placed Hydrogen-Bonding Residues Convert A Proton Pump Into A Sensory Receptor, Yuki Sudo, John L Spudich

Faculty, Staff and Student Publications

In haloarchaea, light-driven ion transporters have been modified by evolution to produce sensory receptors that relay light signals to transducer proteins controlling motility behavior. The proton pump bacteriorhodopsin and the phototaxis receptor sensory rhodopsin II (SRII) differ by 74% of their residues, with nearly all conserved residues within the photoreactive retinal-binding pocket in the membrane-embedded center of the proteins. Here, we show that three residues in bacteriorhodopsin replaced by the corresponding residues in SRII enable bacteriorhodopsin to efficiently relay the retinal photoisomerization signal to the SRII integral membrane transducer (HtrII) and induce robust phototaxis responses. A single replacement (Ala-215-Thr), bridging …
