This paper explains novel CPU scheduling approach for embedded operating Systems. In this approach we have used genetic algorithm (GA). Proposed Adaptive algorithm combines both EDF and GA based algorithms, Basically the new algorithm uses EDF algorithm but when the system becomes overloaded, it will switch to GA based scheduling algorithm. Again, when the overload disappears, the system will s...

This paper presents a feature-based machine vision system for estimating lanedeparture of a traveling vehicle on a road. The system uses edge information to define an edge distribution function (EDF), the histogram of edge magnitudes with respect to edge orientation angle. The EDF enables the edge-related information and the lane-related information to be connected. Examining the EDF by the sha...

In this paper we extend the results for the mixed scheduling algorithm of Liu and Layland in [3]. It is the seminal paper for the basic real-time scheduling algorithms: Rate Monotonic Scheduling (RMS) and Earliest Deadline First (EDF) Scheduling, and for their corresponding schedulability tests [1,2,4,5,7]. In a final section of the paper the authors also investigate the mixed scheduling algori...

The Controller Area Network has a maximum transmission rate of 1 Mbitk and its fixed priorities-based medium access control limits the maximum bus utilisation when timeliness guarantees are required. An implementation of earliest deadline first (EDF) message scheduling on CAN, based on the F’IT CAN protocol, is presented, which allows higher utilisation factors with timeliness guarantees. The a...

Orbital angular momentum (OAM) mode division multiplexing (MDM) amplification in a seven-ring-core erbium-doped fiber (7-RC-EDF) has been experimentally demonstrated, which the 1 st -4 xmlns:xlink="http://www.w3.org/1999/xlink">th order OAM modes within each core of 7-RC-EDF can be support...

Factors stimulating eosinophil differentiation in vitro have been studied by means of a liquid bone marrow culture system in which the number of eosinophils is estimated directly by morphology or indirectly by assay for eosinophil peroxidase. The results show that eosinophil colonies are not formed in agar, emphasizing the importance of the liquid culture system. Three types of evidence identif...

Future ATM networks will support real-time voice and video services and we need to guarantee cell transfer delay and cell loss probability to launch such services. The Earliest Deadline First (EDF) scheme is a suitable service scheduling scheme for these services since it has been proven that it can minimize the number of late cells by assigning deadlines to the cells. However, the EDF scheme c...

In this work, we propose an Expert Decision Fusion (EDF) system to tackle the large-scale indoor/outdoor image classification problem using two key ideas, namely, data grouping and decision stacking. By data grouping, we partition the entire data space into multiple disjoint sub-spaces so that a more accurate prediction model can be trained in each sub-space. After data grouping, the EDF system...

This paper presents a sensitivity analysis for the dimensioning of realtime systems in which sporadic tasks are executed according to the preemptive Earliest Deadline First (EDF) scheduling policy. The timeliness constraints of the tasks are expressed in terms of late termination deadlines. New results for EDF are shown, which enable us to determine the C-space feasibility domain valid for any ...

Ambient energy harvesting also known as energy scavenging is the process where energy is obtained from the environment, converted, and stored to power small devices such as wireless sensors. We present a variant of EDF scheduling algorithm called EH-EDF (Energy Harvesting-Earliest Deadline First). Decisions are taken at run-time without having prior knowledge about the future energy production ...
