Speed Factory Automated Checkpoint Log System for Bike Races
Abstract
The idea of the project is to add an RFID on every bike participating in race/rally and to setup microcontroller based RFID readers at several checkpoints along the route. The microcontroller boards will be equipped with RTC (real time clock) to keep the log of time and EEPROM to maintain log of cross timings for all the bikes. Later the data from all such microcontroller units can be transferred to a centralized database via serial like provided ....etc

Discovery of Periodic Patterns in Spatiotemporal Sequences- IEEE TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERING, VOL. 19, NO.

java


Abstract—
In many applications that track and analyze spatiotemporal data, movements obey periodic patterns; the objects follow the same routes (approximately) over regular time intervals. For example, people wake up at the same time and follow more or less the same route to their work everyday. The discovery of hidden periodic patterns in spatiotemporal data could unveil important information to ....etc

ABSTRACT


The ˜Event Log Book Maintenance™ is one of the modules of ˜ Power Company ™ . This records the power plant™s information on day to day and periodic basis, which is vital when the history of plant is required. In this plant, regular analysis of the utilization of resources is to be measured and records of isolated equipment are to be maintained. Weekly walkthroughs are to be done to feel, observe and record the defects of the machinery. Sometimes, machinery which are to be repaired, are kept open, ma ....etc

Abstract
In this paper, we propose to embed the watermark
information in the log-2-spatio domain by means of
spread spectrum technique. In log-2-spatio domain,
the variance of the information is reduced
significantly. This improves the efficiency and
robustness of spread spectrum technique. Low
intensity and mid-band regions are selected to embed
the information in order to guarantee an invisible
watermark as well as the robustness to JPEG
compression. Simulation results show that the
embedded information still survive up to ....etc
