Partitioning and global scheduling are two approaches for scheduling real-time tasks on multiprocessors. Though partitioning is sub-optimal, it has traditionally been preferred; this is mainly due to the fact that well-understood uniprocessor scheduling algorithms can be used on each processor. In recent years, global-scheduling algorithms based on the concept of “proportionate fairness” (Pfair...

BACKGROUND AND AIMS Predicting light partitioning in crop mixtures is a critical step in improving the productivity of such complex systems, and light interception has been shown to be closely linked to plant architecture. The aim of the present work was to analyse the relationships between plant architecture and light partitioning within wheat-pea (Triticum aestivum-Pisum sativum) mixtures. An...

Temporal clustering refers to the partitioning of a time series into multiple nonoverlapping segments that belong to k temporal clusters, in such a way that segments in the same cluster are more similar to each other than to those in other clusters. Temporal clustering is a fundamental task in many fields, such as computer animation, computer vision, health care, and robotics. The applications ...

1. Knowledge of biomass partitioning is essential for estimating spatial patterns and temporal dynamics of root biomass in terrestrial ecosystems. The isometric hypothesis predicts that aboveground biomass scales isometrically with belowground biomass across both individual plants and community types (i.e. the slope of the log–log relationship between aboveand belowground biomass is not signifi...

Cell signaling underlies transcription/epigenetic control of a vast majority of cell-fate decisions. A key goal in cell signaling studies is to identify the set of kinases that underlie key signaling events. In a typical phosphoproteomics study, phosphorylation sites (substrates) of active kinases are quantified proteome-wide. By analyzing the activities of phosphorylation sites over a time-cou...

* Mr. S. Maćkowiak is Fellow of the Foundation for Polish Science. Abstract The paper deals with a three-layer video coder based on spatio-temporal scalability and data partitioning. The proposed coder consists of two parts: a low-resolution coder and full-resolution coder. The first part encodes pictures with reduced spatial and temporal resolution. The full-resolution encoder exploits interpo...

This paper proposes a cost model for selectivity estimation of predictive spatio-temporal window queries. Initially, we focus on uniform data proposing formulae that capture both points and rectangles, and any type of object/query mobility combination (i.e., dynamic objects, dynamic queries or both). Then, we apply the model to non-uniform datasets by introducing spatio-temporal histograms, whi...

Video segmentation aims at partitioning consecutive video frames and grouping the spatial-temporal voxels into perceptually coherent regions. Video segmentation has a more general objective than image segmentation because video has temporal information included. There are many plausible video segmentation methods available in this community right now and most video segmentation algorithms are u...

In this paper, we describe the the planning system SGPlan6 participating in the satisficing tracks of the deterministic part of the Sixth Planning Competition (IPC6). SGPlan6 is designed to solve both temporal and non-temporal planning problems specified in PDDL3 which may have soft goals, derived predicates or ADL features. SGPlan6 inherited the parallel decomposition framework from SGPlan5 wh...
