This paper presents a field-programmable gate array (FPGA)-based design, implementation, and measurement of high-speed telemetry system for well-logging. In the application geophysics, is an essential part. With continuous development new logging theory methods, must accurately upload more information in real-time. The methods techniques used to improve data transmission system’s performance ha...

Data logging has been a standard, but under utilized, software evaluation technique for single-user systems. Large volumes of objective data can be collected automatically and unobtrusively. This data, however, is usually in the form of low-level system events, making it difficult to analyze and interpret meaningfully. In this paper we extend traditional logging approaches to collaborative mult...

This paper reviews the advancements made in ambulatory data logging used in the study of human subjects since the inception of the analogue tape based data logger in the 1960s. Research into the area of ambulatory monitoring has been rejuvenated due to the development of novel storage technologies during the 1990s. Data logging systems that were previously impractical due to lack of processing ...

Wal-Mart has created tremendous economic benefits for consumers by providing more choices at lower prices, especially in communities that had only local retail monopolies prior to the chain‘s arrival. Yet no retailer evokes stronger negative emotions than this chain. Recent media attention has focused on questionable labor practices and other impacts of the stores, while academic studies have e...

This paper investigates the impact of store location, a retailer's most costly and long-term marketing mix decision, on retailer revenues. We estimate models of consumer spending at the leading packaged goods retailers in a metropolitan market based on two dimensions of retail location: (i) proximity to consumers, i.e., travel times, and (ii) proximity to other stores, i.e., agglomeration. Both...

A database snapshot mechanism rcprcsents a cost effectivc substitute for replicated data in a distributed database. The contents of a database snapshot can be periodically refreshed to reflect the current state of the database. In a distributed database system it is sign& icant to reduce the cost of snapshot refresh. This can be obtained by a differential refresh strategy in which modifications...

Despite considerable debate as to Wal-Mart’s impact on retail workers, to date there has been little structural analysis on the topic. This paper measures and tests for Wal-Mart’s monopsony power in local labor markets using a dominant-firm model and data on contiguous U.S. counties where the company operates. Empirical results show that Wal-Mart’s monopsony power over workers varies significan...

Logging and replay of federation execution data are clearly useful for a number of purposes including after action review, demonstrations, analysis, and debugging. The advent of the HLA and its RTI, while clearly affording substantial payoffs in terms of abstraction, interoperability, and reuse, have a number of implications for simulation system architectures, Federate application software, Fe...
