This paper examines wireless networking and provides a case study of a wireless network infrastructure’s development at an urban university of 11,000 students. The University of Houston – Downtown (UHD) incorporated wireless technology to help users stay connected to the school’s network for access to curricula-related products at any time and from any location.

The size of the bioavailable (i.e., “fixed”) nitrogen inventory in the ocean influences global marine productivity and the biological carbon pump. Despite its importance, the pre-industrial rates for the major source and sink terms of the oceanic fixed nitrogen budget, N2 fixation and denitrification, respectively, are not well known. These processes leave distinguishable imprints on the ratio ...

We study all-pay auctions with budget-constrained bidders who have access to fair insurance before bidding simultaneously over a prize. We characterize a unique equilibrium for the special cases of two bidders and one prize, show existence and a heuristic for finding an equilibrium in the case of multiple bidders and multiple prizes. We end with an example of non-uniqueness of equilibria for th...

Recently, cloud computing has drawn significant attention from both industry and academia, bringing unprecedented changes to computing and information technology. The infrastructure-as-a-Service (IaaS) model offers new abilities such as the elastic provisioning and relinquishing of computing resources in response to workload fluctuations. However, because the demand for resources dynamically ch...

The design of truthful auctions that approximate the optimal expected revenue is a central problem in algorithmic mechanism design. 30 years after Myerson’s characterization of Bayesian optimal auctions in single-parameter domains [9], characterizing but also providing efficient mechanisms for multi-parameter domains still remains a very important unsolved problem. Our work improves upon recent...

Demand theory can be applied to analyse how a human or animal consumer changes her selection of commodities within a certain budget in response to changes in price of those commodities. This change in consumption assessed over a range of prices is defined as demand elasticity. Previously, income-compensated and income-uncompensated price changes have been investigated using human and animal con...

This paper presents a strategy based on fault diagnosability maximization for optimally locating sensors in Fuel Cell Stack Systems. The goal is to characterize and determine a sensor set that guarantees a maximum degree of diagnosability and does not exceeds a maximum sensor set cost constraint. The strategy is based on the structural model of the system in study. Structural analysis is a powe...

Unit quaternion is an ideal parameterization for joint rotations. However, due to the complexity of the geometry of S group, it’s hard to specify meaningful joint constraints with unit quaternion. In this paper, we have proposed an effective and accurate method to specify the rotation limits for joints parameterized with the unit quaternion. Joint constrains constructed with our method are adeq...

In this paper we present a mechanism for determining nearoptimal prices for tasks in online labor markets, often used for crowdsourcing. In particular, the mechanisms are designed to handle the intricacies of markets like Mechanical Turk where workers arrive online and requesters have budget constraints. The mechanism is incentive compatible, budget feasible, and has competitive ratio performan...

The application system while executing in a Grid environment may encounter a failure. This phenomenon can be overcome by a reliable scheduler who plays the major role of allocating the applications to the reliable resources based on the reliability requirement of the applications given by the users. The reliability requirement considered in this paper is deadline and budget which is also the qu...
