Dynamic Load Modulation of High Power Amplifiers with Varactor-Based Matching Networks
"... Abstract — In this paper, the results of dynamic load modu-lation on a high power amplifier is shown with experiments. A simple static nonlinear model is used as an inverse model, and by dynamically controlling both the input signal to the power amplifier and the load impedance, high efficiency oper ..."

High Efficiency Microwave Amplifiers and SiC Varactors Optimized for Dynamic Load Modulation
"... ii The increasing use of mobile networks as the main source of internet connectiv-ity is creating challenges in the infrastructure. Customer demand is a moving target and continuous hardware developments are necessary to supply higher data rates in an environmentally sustainable and cost effective w ..."

way. This the-sis reviews and advances the status of realizing wideband and high efficiency power amplifiers, which will facilitate improvements in network capacity and energy efficiency. Several demonstrator PAs are proposed, analyzed, designed, and character-ized: First, resistive loading at higher
A dynamic operating system for sensor nodes
- in MobiSys
, 2005
"... Sensor network nodes exhibit characteristics of both embedded systems and general-purpose systems. As an embedded system, a sensor node must use little energy and be robust to environmental conditions. As a general-purpose system, a node should provide common services that make it easy to write appl ..."

SOS consists of dynamically-loaded modules and a common kernel, which implements messaging, dynamic memory, and module loading and unloading, among other services
Efficient, Transparent and Comprehensive Runtime Code Manipulation
, 2004
"... This thesis addresses the challenges of building a software system for general-purpose runtime code manipulation. Modern applications, with dynamically-loaded modules and dynamicallygenerated code, are assembled at runtime. While it was once feasible at compile time to observe and manipulate every i ..."

Importing the Gnu Multiple Precision Package (GMP) into Lisp, and implications for Functional Programming
, 2003
"... Advocating the use of a Common Lisp as a central organizing environment for building scientific computing systems runs counter to the conventional wisdom, which suggests that languages like Fortran, C++, or even Java, are more suitable. We prefer Lisp based on its debugging features, interactivity, ..."

, memory model, existing code-base for computer algebra and user interfaces, and for purposes of this paper, its ability to dynamically load modules written in other languages. GMP is an open-source highly-tuned library of programs for arbitrary precision integer, rational and floating-point arithmetic
Packet Routing in Dynamically Changing Networks: A Reinforcement Learning Approach
- Advances in Neural Information Processing Systems 6
, 1994
"... This paper describes the Q-routing algorithm for packet routing, in which a reinforcement learning module is embedded into each node of a switching network. Only local communication is used by each node to keep accurate statistics on which routing decisions lead to minimal delivery times. In simple ..."

experiments involving a 36-node, irregularly connected network, Q-routing proves superior to a nonadaptive algorithm based on precomputed shortest paths and is able to route efficiently even when critical aspects of the simulation, such as the network load, are allowed to vary dynamically. The paper concludes
Type-Safe Updating for Modular WSN Software
"... Abstract—Modular software, in which strongly-separated units of functionality can be independently added to and removed from a node’s running software, offers a promising approach to effective dynamic software updating in Wireless Sensor Networks (WSNs). Modular software updating approaches offer hi ..."

This precludes compile-time or composition-time verification of interoperability between dynamically loaded modules and therefore presents major risks for future large-scale productionclass deployments. In this paper we present Lorien: a componentbased modular operating environment that employs

CLEO’s User Centric Data Access System
"... When analyzing data, physicists want to spend their time studying the data instead of learning about and writing and debugging code for the data access system. We have tried to create a data access system that minimizes both the learning curve and code writing time. The system is built on a simple d ..."
