Running large-scale behavioral simulations requires high computational power, which can be acquired by distributing computation workload to multiple computing nodes (i.e., workers) that run in parallel. The implementations of such systems commonly follow the Bulk Synchronous Parallel (BSP) model. However, implementations using BSP usually suffer from the straggler problem, where the delay of any worker...
Asynchronous circuits are interesting alternatives for implementing ultra-low power systems but they are more challenging to design. This work provides methods for designers to specify, verify, and implement self-timed pipelines. The connection of standard primitives allows specifying a control circuit. A method to derive a Petri net based model of this circuit is presented. The modeled transactions...
Machinima is which use real-time graphics rendering platform game engine to create animated videos or films. Traditional methods of machinima filming are stand-alone methods that using artificial intelligence scripting to implement the plot. However, massive script writing work of artificial intelligence will cost a IoT of manpower and resources. This paper proposes a method based on network game...
Many applications have irregular behavior — e.g., input-dependent solvers, irregular memory accesses, or unbiased branches — that cannot be captured using today's automated performance modeling techniques. We describe new hierarchical critical path analyses for the Palm model generation tool. To obtain a good tradeoff between model accuracy, generality, and generation cost, we combine static and dynamic...

In applications involving unmanned aerial vehicles, the use of simulation environments is typically employed to speed up the development phase, reduce the associated costs, and in particular to safely verify and validate the software behavior without jeopardizing the hardware in case of faults or bugs. In addition, testing other properties as scalability, robustness, and fault tolerance is much more...
Cooperation of multiple UAVs could improve the combat effectiveness. Cooperation efficiency of cooperation architecture is critical for combat effectiveness. In this paper, cooperation architectures are classified, basic models of cooperation efficiency are established, and cooperation efficiency of two cooperation architectures is analyzed and compared. Experimental results show that cooperation...
As knowledge bases are constantly evolving, there is a clear need for monitoring and analyzing the changes that occur on them. Traditional approaches for studying the evolution of data focus on providing humans with deltas that include loads of information. In this work, we envision a processing model that recommends evolution measures taking into account particular challenges, such as relatedness,...
The problem of collecting, processing, and learning from high-volume mobile device data has become an active research area in recent years. Time series data on application usage, in particular promises to provide fine-grained information on individual activity patterns, but currently poses collection and analysis challenges. In this paper we demonstrate an integrated system which can cheaply and easily...
An 8×8 (64) Internet of Things (IoT) wind farm platform is built using miniaturized wind turbines with wireless connectivity. The farm is being deployed on the south east coast of Ireland to remotely collect data for offline evaluation of a data driven wind turbine power output model and study aerodynamic interactions between turbines within the farm. The cluster is build such that a range of different...
In this paper the technique of data synchronization between a smartphone and smart watch is presented. As the example the mobile applications for sports are shown. The development and research were made using the operating system macOS 10.11.6. The development of the program was carried out in an environment Xcode, using the programming language Swift.
In Machine learning (ML) the model we use is increasingly important, and the model's parameters, the key point of the ML, are adjusted through iteratively processing a training dataset until convergence. Although data-parallel ML systems often engage a perfect error tolerance when synchronizing the model parameters for maximizing parallelism, the synchronization of model parameters may delay in completion,...
Hardware in-the-loop simulation test has the advantage of live test, digital simulation test, which can build the lifelike test environment. This kind of test can carry through repeated test of multi-sample. The key technique of the hardware in-the-loop simulation test is real-time algorithmic and communication technology. In this paper, based on reflective memory network, the design for hardware...
Understanding the impact of global climate change on the world's ecosystem is critical to society at large and represents a significant challenge to researchers in the climate community. One important piece of the climate puzzle is how the dynamics of large-scale ice sheets, such as those covering Greenland and Antarctica, will respond to a warming climate. Relatively recently, glaciologists have...
Parallel discrete-event simulation (PDES) is an important tool in the codesign of extreme-scale systems because PDES provides a cost-effective way to evaluate designs of high-performance computing systems. Optimistic synchronization algorithms for PDES, such as Time Warp, allow events to be processed without global synchronization among the processing elements. A rollback mechanism is provided when...
We consider the emerging field of music score libraries, where documents rely on a music notation markup language such as MusicXML or MEI. We propose to model as synchronized time-series the music structure that can be extracted from such documents, together with an algebra that operates in closed form and allows manipulations, restructurings, and combinations of music scores stored in a database...
In the context of industrial designs, circuits are based on many IPs defined on their own clock domain. It leads to globally asynchronous locally synchronous designs. The transmission of data between clock domains must be carefully verified to avoid metastability, inconsistency and data loss. EDA tools propose a strategy based on a minimal detection of a synchronizer structure. Conversely, in this...
Real time is one of fundamental characteristics for hardware in the loop simulation (HILS). In this paper, we adopt the fiber reflective memory net (RMN) strategy to ensure the real-time data transmission and propose a clock synchronization method based on reflective memory card (RFM) interruption to make the simulation process stable. The character of RFM is real-time, delay determinacy and reliability...
Obsessive Compulsive Disorders causes disruptive effect on brain oscillations. One of this disruptive effects is loss of synchronization. Global Field Synchronization indice that is calculated by Global Field Synchronization Method can detect degree of synchronization of EEG. According to analysis results, significantly difference was found between Global Field Synchronization Indice of OCD patients...
We consider an acquisition system constituted by an array of sensors scanning an image. Each sensor produces a sequence of readouts, called a time series. In this framework, we discuss the image estimation problem when the time series are affected by noise and by a time shift. In particular, we introduce an appropriate data model and consider the least squares (LS) estimate, showing that it has no...
