Qasim Ali Arain Beijing University of Posts and Telecommunications (BUPT), P.R, China Abstract— The road networks, vehicle users could enjoy numerous kind of services such as location based service in vehicle users can connected to Internet and communication of different users. Therefore, in order to acquire adequate privacy level and quality of service, one must have to wisely place mix zones ...

This article extends the analysis of table mixes for restaurants, on the principle that table mix helps drive revenue. The article presents the results of a simulation experiment of more than forty-six thousand restaurant contexts to evaluate the accuracy of “naïve table mix” calculations. An earlier study presented a simple method of calculating a recommended mix of tables in a restaurant, and...

In this paper we present eFarnel, a new electronic voting scheme based on the paper-based Farnel protocol. The new scheme corrects problems observed in previous proposes to simulate Farnel electronically. Moreover, we also define a new kind of mix net, called F-Mix-Net, which is required by our protocol.

A MIX net takes a list of ciphertexts (c1; ; cN) and outputs a permuted list of the plaintexts (m1; ; mN) without revealing the relationship between (c1; ; cN) and (m1; ; mN). This paper shows that the Jakobsson's ash MIX of PODC'99, which was believed to be the most eecient robust MIX net, is broken. The rst MIX server can prevent computing the correct output with probability 1 in our attack. ...

Safety critical applications for recently proposed vehicle to vehicle ad-hoc networks (VANETs) rely on a beacon signal, which poses a threat to privacy since it could allow a vehicle to be tracked. Mix-zones, where vehicles encrypt their transmissions and then change their identifiers, have been proposed as a solution to this problem. In this work, we describe a formal analysis of mix-zones. We...

OBJECTIVES It is difficult to draw conclusions about the prudence of antibiotic use in different hospitals by directly comparing usage figures. We present a patient case-mix adjustment model of antibiotic use to rank hospitals while taking patient characteristics into account. PATIENTS AND METHODS Data on antibiotic use were collected during the national healthcare-associated infection (HAI) ...

Pressures related to emergency department (ED) overcrowding and cost containment make it increasingly important to characterize the patients we serve and analyze the work we do; but until recently, few EDs have been able to track or describe their case mix, care processes, workloads, utilization, efficiency or patient outcomes. Regional health authorities across Canada have identified electroni...

BACKGROUND Adequate resource allocation is an important factor to ensure equity in health care. Previous reimbursement models have been based on age, gender and socioeconomic factors. An explanatory model based on individual need of primary health care (PHC) has not yet been used in Sweden to allocate resources. The aim of this study was to examine to what extent the ACG case-mix system could e...

BACKGROUND The Balanced Budget Refinement Act of 1999 included a Congressional mandate to develop a patient-level case mix prospective payment system (PPS) for all Medicare beneficiaries treated in PPS-exempt psychiatric facilities. Payment levels by case mix category have been proposed by the government based on claims and facility cost reports. Because of claims data limitations, these levels...

BACKGROUND Reprocessing dialysers is a common cost-saving practice in the USA. It began when patients were treated with bio-incompatible cellulosic membranes that were associated with medical complications, but has continued for economic reasons despite the current use of more biocompatible non-cellulosic membranes. A dialysis services and product provider using primarily its own non-cellulosic...
