TL;DR: In this paper, the authors describe a system monitor embedded in a programmable logic device (PLCD), which includes an analog-to-digital converter which is reconfigurable responsive to input via a dynamic reconfiguration port.
Abstract: Method and apparatus for a system monitor embedded in a programmable logic device are described. The system monitor includes a dynamic reconfiguration port interface for configuring or reconfiguring the system monitor during operation thereof. The system monitor includes an analog-to-digital converter which is reconfigurable responsive to input via a dynamic reconfiguration port.

TL;DR: This work provides three main distributed services: lookup service, composition service and dynamic adaptation service that enable dynamic adaptation of these services to incremental addition and removal of sensor nodes, device failure and degradation, migration of sensor node nodes, and changing requirements in tasks and networks.
Abstract: Dynamic enterprise systems, such as the battlefield, use self-organizing sensor network infrastructure to gather and disseminate real-time information for controlling the enterprise. Very large number of highly mobile sensor data sources and users may be scattered over a wide area with little or no fixed network support. These large surveillance sensor networks must adapt rapidly to dynamic changes in sensor nodes configuration. Dynamic query processing and target tracking through this unstructured sensor network of surveillance information sources and users must use the appropriate distributed services and network protocols to solve the problems of mobility, dispersion, weak and intermittent disconnection, dynamic reconfiguration and limited power availability. We provide three main distributed services: lookup service, composition service and dynamic adaptation service. Through a distributed implementation of these services, other application-specific network and system services can be defined spontaneously in the sensor network. They also enable dynamic adaptation of these services to incremental addition and removal of sensor nodes, device failure and degradation, migration of sensor nodes, and changing requirements in tasks and networks. When placed together impromptu, sensor nodes should immediately know about the capabilities and functions of other smart nodes and work together as a community system to perform coordinated tasks and networking functionalities.

TL;DR: This analysis aims to assess if and how the mobility system is reconfiguring in low-carbon directions and provides an interpretive assessment of the 12.7% decrease in domestic transport-related CO2-emissions between 2007 and 2013.
Abstract: Low-carbon transitions in whole systems (in energy, mobility, agro-food) are an important, yet understudied topic in socio-technical transition research. To address this topic, the paper builds on the Multi-Level Perspective, but stretches it to address developments in multiple regimes and multiple niche-innovations. This ‘zooming out’ strategy changes the conceptualisation of transition dynamics from bottom-up disruption (driven by singular niche-innovations) to gradual system reconfiguration, which represents a more distributed, multi-source view of change that includes cumulative incremental regime change, shifts in relative sizes of regimes, regime alignments, component substitution, and symbiotic adoption. To illustrate the reconfiguration approach and empirically explore the topic of whole system change, the paper investigates unfolding trajectories in UK passenger mobility. This analysis, which addresses developments in auto-mobility, train, bus and cycling regimes and five niche-innovations (biofuels, electric vehicles, smart cards, compact cities, home working), aims to assess if and how the mobility system is reconfiguring in low-carbon directions. It also aims to provide an interpretive assessment of the 12.7% decrease in domestic transport-related CO2-emissions between 2007 and 2013. This decrease is attributed to reduced auto-mobility (due to the financial-economic crisis), incremental engine efficiency improvements in new cars, some modal shift from cars to trains, and biofuels. Radical niche-innovations (smart cards, compact cities, electric vehicles) did not (yet) greatly contribute to emission reductions. CO2-emissions increased again since 2014, which suggests that further low-carbon transitions require deeper system reconfiguration.

TL;DR: The need for scalable machines is established and a basis for evaluating and describing them is established, Applicable metrics are defined, and an architecture for scalable Machines is presented, and a design parameter based on a mathematical approach is presented.
Abstract: Scalability is one of six key characteristics found in reconfigurable manufacturing systems. Scalable systems satisfy changing capacity requirements efficiently through system reconfiguration, and in the flexible manufacturing literature this capability is called expansion flexibility. The development of modular scalable machine tools is a necessary precursor to achieving scalable systems. Unfortunately, there is little work describing the design of scalable machines. This paper establishes the need for scalable machines and a basis for evaluating and describing them. Applicable metrics are defined, and an architecture for scalable machines is presented. Two examples illustrate the scalable architecture. Finally, a design parameter based on a mathematical approach is presented to determine the optimal number of modules to be included on a modular scalable machine. This as a design parameter is important because it limits machine size and the number of module interfaces included in the base machine structure.
