Data prefetching is a technique that plays a crucial role in modern high-performance processors by hiding long latency memory accesses. Several state-of-the-art hardware prefetchers exploit the concept of deltas, defined as the difference between the ...

Some past and future supercomputer nodes incorporate High- Bandwidth Memory (HBM). Compared to standard DRAM, HBM has similar latency, higher bandwidth and lower capacity.

In this paper, we evaluate algorithms for managing High- Bandwidth Memory ...

Intermittently powered energy-harvesting devices enable new applications in inaccessible environments. Program executions must be robust to unpredictable power failures, introducing new challenges in programmability and correctness. One hard problem is ...

Time plays a major role in the specification of Cyber-physical Systems (CPS) behavior with concurrency, timeliness, asynchrony, and resource limits as their main characteristics. In addition to timeliness, the specification of CPS needs to assess and ...

The Internet of Things (IoT) consists of embedded sensors that transmit events over a wireless network. Complex event processing provides powerful abstractions to aggregate and analyze relationships among event streams in real time, which can improve ...

Economic policymakers express concern that procyclical lending by banks imperils financial stability. Prior research finds that banks that record timelier loan loss provisions originate more loans during downturns, consistent with loan loss–provision ...

Aiming at the problem of low timeliness in social network recommendation systems, a new social network recommendation algorithm using information aging was presented in this paper. The paper proposed a trust network recommendation system based on trust ...

By collectively leveraging advanced communications systems, sensing, drones, wearable technologies and large-scale data analysis, smart firefighting is envisioned as the next generation firefighting with the capacities of gathering massive real-time ...

Industrial applications and cyber-physical systems rely on real-time wireless networks to deliver data in a timely and reliable manner. However, existing solutions provide these guarantees only for stationary nodes. In this article, we present REWIMO, a ...

One of the major advantages of communication middleware is its independence from the underlying hardware platform. This improves portability and interoperability, whereas following the mainstream trend of favoring abstraction over performance or ...

Autonomous systems have become more and more important in today's transport sector. They often operate in dynamic environments in which unpredictable events may occur at any time. These events may affect the safe operation of vehicles, calling for ...

A significant challenge we face in assessing spatio-temporal data quality is a lack of ground-truth data. Error is by definition the deviation of observation from ground truth. In the absence of ground truth, we depend on our own or provider quality ...

Traditional Concurrency Control (CC) mechanisms ensure absence of undesired interference in transaction-based systems and enforce isolation. However, CC may introduce unpredictable delays that could lead to breached timeliness, which is unwanted for ...

Unmanned autonomous systems (UAS) avionics call for advanced computing system architectures fulfilling strict size, weight and power consumption (SWaP) requisites, decreasing the vehicle cost and ensuring the safety and timeliness of the system. The AIR ...

Data aggregation has emerged as a basic concept in wireless sensor networks. By combining data and eliminating redundancy, this concept showed its effectiveness in terms of reducing resources consumption. The data aggregation problem is not new and has ...

Problems are ever-present in nearly all engineered systems. A Systems Engineering Problem Management Process SEPMP has been proposed, and this research presents empirical evidence to support its validity. In order to evaluate the SEPMP, which uses a ...

With the rapidly growing number of Web services, how to identify high quality Web services becomes a hot research topic. User-side QoS evaluation on Web services is a key measurement to choose the optimal Web service from a set of Web services with ...

In this article, we propose and analyze dynamic redundancy management of integrated intrusion detection and tolerance for lifetime maximization of homogeneous clustered wireless sensor networks (WSNs). We take a holistic approach of integrating ...

Networking communications play an important role to secure a dependable and timely operation of distributed and real-time embedded system applications; however, an effective real-time support is not yet properly addressed in the wireless realm. This ...

A robust trust management model based on recommendation was proposed to deal with three kinds of common attacks in E-commerce system including self-promoting attack, slandering attack and whitewashing attack. This paper introduced some new concepts such ...
