This paper presents a novel logging scheme for recov-erable distributed shared memory systems. In the previous schemes, the stable logging is performed whenever a remote data value is accessed. However, in the proposed scheme, the data values are logged on the volatile storage of the writer process and only the access information between the dependent processes is logged stably. Also, to reduce...

In the existing Fault-Tolerant Software Distributed Shared Memory (FT-SDSM) with the message logging, the logs are used only to recover the failed nodes. In our previous work, we have implemented a lightweight logging protocol, called remote logging, on the SDSM for fault tolerance, which incurs low logging overhead with a fast network and a remote memory for back-up data. In this paper, we pro...

The Measurement/Logging While Drilling (M/LWD) system is a kind of sensors system which is used to help oil/gas drilling field technicians to steer well drilling. In M/LWD, several kinds of sensors are installed into drill string to measure the underground logging data during well drilling operations, and a sink within the drill string collects the logging data from the sensors and then transmi...

Many real-world applications wish to collect tamperevident logs for forensic purposes. This paper considers the case of an untrusted logger, serving a number of clients who wish to store their events in the log, and kept honest by a number of auditors who will challenge the logger to prove its correct behavior. We propose semantics of tamper-evident logs in terms of this auditing process. The l...

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...
