Floral nectar is an important attractant and reward for visitors, often produced in synchrony with peak activity of pollinators. Aloe peglerae flowers winter, previous studies have shown that it pollinated primarily by diurnal generalist birds, small mammals making additional contributions to pollination at night. Nectar during the day main but rewards available are unknown. This paper investig...

Limited information exists about the temporal residency patterns of marine predators, especially at individual level. Temporal partitioning resources can reduce intra-specific competition, but this has seldom been examined in predators ecosystems. Here, we used 8 years acoustic telemetry data from 27 receivers deployed a large coastal embayment to examine 51 Port Jackson sharks (Heterodontus po...

We propose a measure for nonstationarity which is based on the analysis of distributions of temporal distances of neighboring vectors in state space. As an extension of previous techniques our method does not require a partitioning of the time series. Moreover, the deviation of mean recurrence times from frequency distributions that would be expected under stationary conditions allows us to est...

We study the partitioning of temporal planning problems formulated as mixed-integer nonlinear programming problems, develop methods to reduce the search space of partitioned subproblems, and propose algorithms for resolving unsatisfied global constraints. The algorithms are based on the necessary and sufficient extended saddle-point condition for constrained local minimization developed in this...

We present an implementation framework for run-time reconfigurable systems. The framework provides a methodology and a design representation which allow to plug in different design tools. Frontend tools cover design capture, temporal partitioning and scheduling; back-end tools provide reconfiguration control, communication channel generation, estimation, and the final code composition. This pap...

For Big Data processing, Apache Spark has been widely accepted. However, when dealing with events or any other spatio-temporal data sets, Spark becomes very inefficient as it does not include any spatial or temporal data types and operators. In this paper we demonstrate our STARK project that adds the required data types and operators, such as spatio-temporal filter and join with various predic...

Random delays and dynamic frequency switching are widely adopted in smartcards and embedded systems as temporal hiding countermeasures to side channel attack.Temporal hiding is regarded as efficient to enhance the security of cryptographic devices. However, spectral analysis with Fast Fourier Transform is a powerful method to defeat temporal hiding countermeasures. Spectral analysis shares the ...

The paper describes a generic multi-loop coder structure suitable for mixed spatial and temporal scalability combined with fine granular SNR scalability. The structure is suitable for various variants of hybrid video coders like MPEG-2, H.263 and H.26L. The idea of mixed spatial and temporal scalability i.e. spatiotemporal scalability is substantial for the proposal. Its application allows impr...

background: precise diagnosis of disease risk factors via efficient statistical models is the primary step for reducing the heavy costs of breast cancer, as one of the most highly prevalent cancer throughout the world. therefore, the aim of this study was to present a recently introduced statistical model in order to assess its proficiency for model fitting. methods: the information of 1465 eli...
