FPGA Stream-Monitoring of Real-time Properties

Real-time Stream-based Monitoring

We introduce RTLola, a new stream-based specification language for the description of real-time properties of reactive systems. In real-time applications, data arrives at varying rates and in most cases it is hard to predict the input rate. The integration of sliding windows over real-time intervals with aggregation functions into RTLola allows us to detach fixed-rate output streams from the va...

Monitoring of Real-Time Properties

This paper presents a construction for runtime monitors that check real-time properties expressed in timed LTL (TLTL). Due to D’Souza’s results, TLTL can be considered a natural extension of LTL towards real-time. Moreover, a typical obstacle in runtime verification is solved both for untimed and timed formulae, in that standard models of linear temporal logic are infinite traces, whereas in ru...

Real-time Monitoring of the Resilience of Stream Ecosystems

FPGA Based Real Time Monitoring System for Agricultural Field

1. Abstract The most important factors for the quality and productivity of plant growth are temperature, humidity, light and the level of the carbon dioxide. Continuous monitoring of these environmental variables gives information to the grower to better understand, how each factor affects growth and how to manage maximal crop productiveness .The optimal greenhouse climate adjustment can enable...

Monitoring Stream Properties for Continuous Query Processing

We are developing a general-purpose Data Stream Management System for processing continuous queries over multiple continuous data streams [MW 03]. When a new continuous query is registered, our query optimizer creates an initial query plan (possibly merged with existing plans for previously registered queries), and allocates initial resources, such as memory for join or aggregation synopses [GG...
