In most experiments in which time is involved, it is necessary to develop estimates of time, frequency and measurement errors from a series of time measurements between the clocks of a number of computers and ancillary devices interconnected by some kind of computer network. However, time is not a physical quantity, such as mass, nor can it be measured relative to an absolute frame of reference...

Since modern high-performance computer systems consist of many hardware components and software layers, they present severe challenges for application developers who are primarily domain scientists and not experts with continually evolving hardware and system software. Effective tools for performance analysis are therefore decisive when developing performant scalable parallel applications. Such...

This study aims to investigate the effect of integrating the Argument-Based Science Inquiry (ABSI) approach with multi-modal representations on students’ achievement, and their argumentation and writing skills. The study was conducted with 62 female and 57 male college students at the Central Anatolian Turkish University. All participants were in their third year of the science education progra...

Many service provider service level agreements (SLAs) depend on the ability to measure and monitor performance metrics for packet loss and one-way and two-way delay, as well as related metrics such as delay variation and channel throughput. This measurement capability also provides operators with greater visibility into the performance characteristics of their networks, thereby facilitating pla...

One of the biggest challenges in wireless communication systems consists in achieving flexible dual-band receivers with maximum hardware share and minimum power consumption. The key for surpassing this challenge is the feasibility and performance evaluation for the different receiver topologies at system level stage. This task has its degree of complexity, by the fact that the receiver blocks c...

Knowledge characteristics are the essential step in leveraging knowledge value in the university. Share Document, and contributes knowledge may not be useful without the context provided by experience. This paper focuses on the characteristics of knowledge in applied science private university and its effect on student’s performance, which aim to focus in the nature knowledge and the quality of...

the researchers aim was to find out the potential effects of some maternal factors such as age, educational level, occupation as well as children’s birth order on the communicative performance of preschoolers in iran. this study was conducted with 31 preschoolers selected from bahar language institute in shiraz, iran. the required data about mothers and children were gathered through a question...

Compared to kernel-level servers, user-level ones can be debugged and maintained more easily and safely, but traditionally have had much worse performance. We describe a novel Z/O-oriented IPC facility that combines the emulated copy data passing scheme for monolithic systems with new copy avoidance techniques for microkernel systems. Unlike previous optimizations, I/O-oriented IPC does not req...
