We studied a system in which 2 desert rodent species coexist through temporal partitioning. Previous research suggests that the common spiny mouse (Acomys cahirinus) competitively forces the golden spiny mouse (A. russatus) into diurnal activity, but the mechanism driving this separation is not entirely understood. To test whether aggression is the driving force in this exclusion, we analyzed i...

Aerospace systems have strict dependability and real-time requirements, as well as a need for flexible resource reallocation and reduced size, weight and power consumption. To cope with these issues, while still maintaining safety and fault containment properties, temporal and spatial partitioning (TSP) principles are employed. In a TSP system, the various onboard functions (avionics, payload) ...

Reconfigurable instruction set processors allow customization for an application domain by extending the core instruction set architecture. Extracting appropriate custom instructions is an important phase for implementing an application on a reconfigurable instruction set processor. A custom instruction (CI) is usually extracted from critical portions of applications and implemented on a reconf...

This paper presents a novel algorithm for temporal partitioning of graphs representing a behavioral description. The algorithm is based on an extension of the traditional static-list scheduling that tailors it to resolve both scheduling and temporal partitioning. The nodes to be mapped into a partition are selected based on a statically computed cost model. The cost for each node integrates com...

Coalescing is a unary operator applicable to temporal databases; it is similar to duplicate elimination in conventional databases. Tu-ples in a temporal relation that agree on the explicit attribute values and that have adjacent or overlapping time periods are candidates for coalescing. Uncoalesced relations can arise in many ways, e.g., via a projection or union operator, or by not enforcing c...

One of the biggest challenges facing current methods for classifying music by genre or artist is that features of the sound are computed on very small temporal scales (20 to 50 milliseconds), while the labels need to be assigned at relatively large temporal scales (3 to 5 minutes). We address this challenge by partitioning songs into smaller pieces and classifying each one separately. Our choic...

Resource partitioning is essential for coexistence of phylogenetically related species in altered environments, where changes biotopes can limit resources and change ecological strategies. We investigated resource between two congeneric catfishes (Hypostomus affinis H. luetkeni) three niche dimensions (trophic, spatial, temporal) a Neotropical reservoir. tested the hypothesis that use different...
