Dynamic Software Product Line (DSPL) provides a new paradigm for developing self-adaptive systems with the principles of software product line engineering. DSPL emphasizes variability analysis and design at development time and variability binding and reconfiguration at runtime, thus requires some kinds of variability mechanisms to map high-level variations (usually represented by features) to ...

Resource efficiency is an increasingly important internal quality attribute of software systems. While the related attribute performance is mainly concerned with metrics quantifying timing behavior and resource usage characteristics, resource efficiency is a measure of a system’s resource usage economy. Many software systems are exposed to varying workload conditions significantly influencing i...

Using optical technology brings with it advantages such as scalability, high bandwidth and power consumption for the design of switches/routers. However, reconfiguring the optical fabric of these switches requires significant time under current technology. Conventional slot-by-slot scheduling may severely cripple the performance of these switches due to its frequent request for fabric reconfigu...

The theoretical ability of modular robots to reconfigure in response to complex tasks in a priori unknown environments has frequently been cited as an advantage, but has never been experimentally demonstrated. For the first time, we present a system that integrates perception, high-level mission planning, and modular robot hardware, allowing a modular robot to autonomously reconfigure in respon...

In this paper, a novel robotic system called modular transformer (M-TRAN) is proposed. M-TRAN is a distributed, self-reconfigurable system composed of homogeneous robotic modules. The system can change its configuration by changing each module’s position and connection. Each module is equipped with an onboard microprocessor, actuators, intermodule communication/power transmission devices and in...

This paper describes the architecture and design flow of a self-reconfigurable embedded system, mapped on Spartan-3 low-cost FPGA. The proposed design flow combines EDK and ISE software along with an ownmade tool, in order to create a self-reconfigurable system able to map a reconfigurable OPB coprocessor. A fixed area of the FPGA is reserved to accommodate a set of coprocessors whose execution...

Self-reconfigurable robots are built from modules, which are autonomously able to change the way they are connected. Such a robot can, through this self-reconfiguration process, change its shape. The process has proved to be difficult to control, because it involves control of a distributed system of mechanically coupled modules connected in time-varying ways. In this paper we present an approa...

In distribution systems, in order to diminish power losses and keep voltage profiles within acceptable limits, network reconfiguration and capacitor placement are commonly used. In this paper, the Hybrid Shuffled Frog Leaping Algorithm (HSFLA) is used to optimize balanced and unbalanced radial distribution systems by means of a network reconfiguration and capacitor placement. High accuracy and ...

Self-reconfigurable robots consist of simple robotic modules that play a similar role in robots as cells play in biological organisms. The vision of self-reconfigurable robots is to make an evolutionary jump for robotics analog to biological organisms that evolved from single-celled to multicelled. Such robots can autonomously self-reconfigure its modules to adjust both its behavior and morphol...
