Application of a recursive subspace identification method to derive a state space model for a synchronous machine is described in this paper. Simulation studies show the effectiveness of such an algorithm to identify on-line a synchronous machine model over a wide range of operating conditions and disturbances. The model provides a foundation for further study on a MIMO adaptive power system st...

Wireless robotics enables wide applications of service robots to benefit human life. However, effective machine-to-machine communications would be the foundation of operation. With cloud-based architecture, we innovatively demonstrate in-network computation to significantly alleviate the requirement of communication bandwidth for multi-hop networking, to achieve spectrum-efficient M2M communica...

There have been many recent advances in pattern recognition technologies, particularly those involving visual pattern recognition tasks. How do these machine capabilities compare to human capabilities in visual pattern recognition tasks? Which can perform better in the feature extraction processes, machine or human? This study compares machine and human in color and shape recognition tasks, as ...

We define an abstract operational semantics for the Business Process Execution Language for Web Services (BPEL) based on the abstract state machine (ASM) formalism. This way, we model the dynamic properties of the key language constructs through the construction of a BPEL abstract machine in terms of a distributed real-time ASM. Specifically, we focus here on the process execution model and the...

In this article, we make the case for a declarative foundation for data-intensive machine learning systems. Instead of creating a new system for each specific flavor of machine learning task, or hardcoding new optimizations, we argue for the use of recursive queries to program a variety of machine learning algorithms. By taking this approach, database query optimization techniques can be utiliz...

This paper investigates the mechanical properties of two different types recycled concrete, which use wood and rubber, relative to those characteristics pure in terms maximum load natural frequencies. contributes state art this area a number ways. Firstly, provides furtherance progressively growing literature field concrete materials. Secondly, by means investigating frequency samples, is new c...

The main purpose of this study was to introduce how a college English teacher conducted cooperative learning techniques and compared them with the traditional teaching methods. In this study the teacher as a researcher employed cooperative learning strategies: Students Teams-Achievement Divisions (STAD). Jigsaw II, Number Head Together, and Learning Together (LT). The researcher employed a qual...

This paper reports on a 1-year longitudinal study that aimed at investigating the relationship between intermediate EFL learners’ development of reading and writing proficiency while delineating a range of linguistic features present in a set of 30 reading comprehension texts and 350 written essays. Data (reading comprehension exam scores and written essays) were collected from a junior high sc...
