BACKGROUND Microcosting studies collect detailed data on resources used and the value of those resources. Such studies are useful for estimating the cost of new technologies or new community-based interventions, for producing estimates in studies that include nonmarket goods, and for studying within-procedure cost variation. OBJECTIVES The objectives of this article were to (1) describe basic...

This paper describes a protocol to protect data collected by mobile agents roaming through a set of potentially malicious hosts. This protocol is based on an original secure cryptographic technique that assures the integrity of a sequence of data segments regardless of the order of each segment in the sequence. The protocol allows each host to update the data it previously submitted in a way th...

Vehicular Sensors Networks (VSNs) are an emerging paradigm in vehicular networks. This new technology uses different kind of sensing devices available in new vehicles, to gather information about the driver’s environment (speed, acceleration, temperature, seats occupations, etc.) in order to provide a safer, more efficient and more comfortable driving experience. In this paper, we focus on a pa...

We study the distributed privacy preserving data collection problem: an untrusted data collector (e.g., a medical research institute) wishes to collect data (e.g., medical records) from a group of respondents (e.g., patients). Each respondent owns a multi-attributed record which contains both non-sensitive (e.g., quasi-identifiers) and sensitive information (e.g., a particular disease), and sub...

We have been actively collecting data within the JUPITER domain since the beginning of 1997. As was done in previous domains, we first developed a prototype JUPITER system and used it to collect spontaneous speech using a Wizard paradigm, with a human typist in the loop and subjects brought into the lab and given scenarios to solve. At the same time, we solicited read speech using both our Web-...

The first presentation, by Dave Pallett, described an evaluation by Pallett, Fiscus, and Garofolo (National Institute for Standards and Technology) of the significance of differences in performance of various speech understanding systems. A number of sites which are developing such systems have been using the DARPA Resource Management Speech Corpora to evaluate their systems. As performance gra...

“point” and “area” (originally film) detectors. The first X-ray diffraction experiment by Friedrich and Knipping [1] used film, but within the same year Bragg was using an ionization chamber mounted on a rotating arm [2]. The advantage of Bragg's X-ray detector was that it defined precisely the angle of the diffracted rays and, in general, gave more accurate intensity measurements. The advantag...

Introduction This pattern guides the design of software components that exchange large amounts of data in order to deliver a certain decision service. The general objective is to minimize the total (i.e. development, maintenance and runtime) cost of the system to be built. After the introduction of a set of basic design scenarios to gather data, the pattern proposes an optimal combination of th...

Recently, three major ICT companies were confronted with public outrage about the way they collected massive amounts of personal data without informing data subjects, let alone obtaining their consent. Google harvested data concerning Wi-Fi routers while cruising around with their StreetView camera cars, Facebook tracked potentially every internet user with the help of tracking cookies and the ...

J95 is a health data collection system aimed at gathering information on the weight of health problems facing the Army in order to allow rational and effective prioritization. Before implementing the system Army-wide, a pilot study has been undertaken to validate the J95 ICD 9-based classification system, to test the practical problems encountered with operating the system and its practical val...
