A fine networks of thermal data loggers has been set up in a viticultural site of the « Coteaux du Layon » to assess spatial variability of temperature within the vineyard. One part of the study aimed to point out wich local factors prevail in the temperature variability and to establish role and weight of each factors. That is why a multicriteria modeling based on multiple linear regressions h...

Remote monitoring of large civil structures in uneasily accesslible locations gains increasing interest. Either the reliability of new contruction technologies has to be verified or the health of a structure has to be assessed. Regular sensors for strain, temperature, load etc. can be easily monitored by conventional data loggers. In cases where not so conventional sensors have to be monitored ...

System administration has become an increasingly important function, with the fundamental task being the inspection of computer log-files. It is not, however, easy to perform such tasks for two reasons. One is the high recognition load of log contents due to the massive amount of textual data. It is a tedious, time-consuming and often error-prone task to read through them. The other problem is ...

We applied the constraint-based approach to develop a web-based diagnosis system for Prolog. In this paper, we introduce the results of our formative evaluation which reflects the current effectiveness of our system. We gathered 261 log files which are created by 99 users contained records of interactions with the tutoring system. In addition, we present the common problems of Prolog novice pro...

Wikis have been reported as tools that promote collaborative writing in educational settings. Examples of wikis in teacher education are group projects, glossary creation, teacher evaluation, and document review. However, in spite of studies that report on successful stories, the claim that wikis support collaborative writing has not yet been firmly confirmed in real educational settings. Most ...

Automatic analysis of discussion logs from studies of computer supported collaborative learning has become more prevalent as technology for machine learning and text mining have become more powerful and usable. We extend this effort to analysis of transcripts of whole group classroom discussions. We argue in favor of adapting a transactivity based framework developed for analysis of collaborati...

Precise temperature monitoring is the major precondition to supervise quality losses within the transport chain for fresh products. Different types of miniaturised data loggers with electrical and semi-passive RFID interface were compared and applied to record spatial temperature profiles for typical transport situations. The resulting effects of the found temperature variations were evaluated ...

A management model for explaining software errors is developed and estimated. The model is used to analyze two years of error log data at a commercial site. The focus is on identifying managerially controllable factors which affect software reliability. At the research site, application systems which (1) underwent frequent modification; (2) were maintained by programmers with low levels of appl...

This paper describes a set of tools that allows a developer to instrument a C/C++ program to log data at run-time and then analyze that data to verify correct behavior. The logging tools provide the developer with a means to log a variety of di erent data to a variety of di erent outputs. They also allow for synchronized logging of data from distributed programs. One logging output option is an...

This paper focuses on a supporting strategy for enhancing distributed and computer-mediated group programming learning. Based on a real-world research setting that started two decades ago, we have exploited a particular context characterized by: (i) a close analysis of artifacts produced by learners; (ii) a collaborative approach to learning, combined with (iii) a team-based approach to program...
