This paper addresses the problem of efficient code generation for embedded reactive real-time systems. Such systems have tight memory-size and execution speed-constraints. A method is proposed based on the theory of Petri net synthesis aiming at reducing the size of the code by exploiting common control structures. Experimental results show that significant improvements can be obtained.

This study proposed a decomposed SCORM (Sharable Course Object Reference Model) structure with embedded LCMS Broker that provides the integration of learning resources and balance of network traffic. The system consists of the Learning Management System (LMS) for processing basic data, learning data and learning records of learners, and the Learning Content Management Systems (LCMSs) for managi...

To understand a discourse, the reader needs to recover the relations between the discourse elements as intended by the writer. Writers can, and very often do, help the reader along by providing explicit lexical signals of the intended discourse relations through the use of lexicalised discourse markers. In this paper we present a novel approach for generating texts containing multiple, embedded...

Membrane-embedded prenyltransferases from the UbiA family catalyze the Mg2+-dependent transfer of a hydrophobic polyprenyl chain onto a variety of acceptor molecules and are involved in the synthesis of molecules that mediate electron transport, including Vitamin K and Coenzyme Q. In humans, missense mutations to the protein UbiA prenyltransferase domain-containing 1 (UBIAD1) are responsible fo...

The characteristics of a PZT ceramic element embedded in concrete are studied in this article. Based on the theory that the material coefficients of ceramic change their values under different stress levels, a method of measuring concrete stress by detecting the characteristics of the embedded ceramic element is proposed. The experiment uses a network analyzer to monitor some physical parameter...

corrosion of reinforcing steel and other embedded metals is the main cause of severe deterioration in reinforced concrete structures which subsequently imposes adverse effects on ultimate and serviceability limit state performance of the whole structure. in this paper, a new corrosion detection method for reinforced concrete beams, based on wavelet analysis is presented. to evaluate the capabil...

the basic structure of a reactor physics laboratory environment simulation software, developed using object modeling technique (omt), and based on the reactor point kinetic equation, is presented. also, various capabilities of the simulator in teaching the fundamental concepts of reactor physics are discussed. in this virtual laboratory, student can perform seven different experiments, namely, ...

This paper presents an object-oriented approach to describe an embedded communication protocol in UML. We build on top of existing work based on object-oriented patterns. We follow the belief that there should exist a generalized structure or pattern on which protocols should be formed. We feel that the system structure is of importance for promoting reuse. These protocol patterns would provide...

This study presents vibration control using actively tunable vibration absorbers (ATVA) to suppress vibration of a thin plate. The ATVA is made of a sandwich hollow structure embedded with electrorheological fluid (ERF). ERF is considered to be one of the most important smart fluids and it is suitable to be embedded in a smart structure due to its controllable rheological property. ERF’s appare...
