1 NANOENERGY LETTERS Whole Systems Energy Transparency
"... Abstract—Energy efficiency is now a major (if not the major) concern in electronic systems engineering. While hardware can be designed to save a modest amount of energy, the potential for savings are far greater at the higher levels of abstraction in the system stack. The greatest savings are expect ..."

are expected from energy consumption-aware software. This article emphasizes the importance of energy transparency from hardware to software as a foundation for energyaware system design. Energy transparency enables a deeper understanding of how algorithms and coding impact on the energy consumption of a
THE EFFECT OF EXTERNAL SURFACE PROPERTIES ON THE THERMAL BEHAVIOUR OF A TRANSPARENTLY INSULATED WALL
"... The properties of transparent plaster covering transparent insulation materials (TIM) were investigated using a whole building simulation program (ESP-r). The outer plaster was made from glass balls of different diameter, glued together with synthetic resin. The transmittance of the whole transparen ..."

Dynamic Thermal Management for Distributed Systems
- IN PROCEEDINGS OF THE FIRST WORKSHOP ON TEMPERATURE-AWARE COMPUTER SYSTEMS (TACS’04
, 2004
"... In modern data centers, the impact on the thermal properties by increased scale and power densities is enormous and poses new challenges on the designers of both computing as well as cooling systems. Controltheoretic techniques have proven to manage the heat dissipation and the temperature to avoid ..."

and the resulting heat generation be controlled precisely without the need for expensive hardware. Experiments on a Pentium 4 architecture show that energy and temperature are accurately determined and thermal limits for the individual CPU and the whole distributed system will not be exceeded.

The UK bio-energy resource base to 2050: estimates, assumptions, and uncertainties Working Paper
"... The UK Energy Research Centre is the focal point for UK research on sustainable energy. It takes a whole systems approach to energy research, drawing on engineering, economics and the physical, environmental and social sciences. The Centre's role is to promote cohesion within the overall UK en ..."

A.: Topological grammars for data approximation
- Applied Mathematics Letters
, 2007
"... A method of topological grammars is proposed for multidimensional data approximation. For data with complex topology we define a principal cubic complex of low dimension and given complexity that gives the best approximation for the dataset. This complex is a generalization of linear and non-linear ..."

. For the energy computation, the whole complex is represented as a system of nodes and springs. Topologically, the principal complex is a product of one-dimensional continuums (represented by graphs), and the grammars describe how these continuums transform during the process of optimal complex construction

Declarative resource naming for macroprogramming wireless networks of embedded systems
- in International Workshop on Algorithmic Aspects of Wireless Sensor Networks (ALGOSENSORS
, 2005
"... Programming Wireless Networks of Embedded Systems (WNES) is notoriously difficult and tedious. To simplify WNES programming, we propose Declarative Resource Naming (DRN) to program WNES as a whole (i.e., macroprogramming) instead of several networked entities. DRN allows programmers to declaratively ..."

Distributed
"... Abstract—Wireless Sensor Networks (WSNs) are deployed for long periods of time, during which a need often arises to dynamically reprogram or retask them. An array of solutions has been proposed to this effect, ranging from full image replacement to virtual machines. However, the capabilities of Tiny ..."

of TinyOS – the current state of the art in sensor node operating systems – are still limited to full image replacement. TinyOS based applications have a modular architecture but during compilation this modularity is lost resulting in a statically linked system image. In this work we extend Tiny
Power and Locality Aware Request Distribution
"... With the growing use of cluster systems in file distribution, web servers and database transactions, efficiency and power optimization have realized a lot of significance. Distributor based systems has been widely adopted, which forward the requests from the clients to a set of waiting balanced serv ..."

We then implement an optimum on-ff power policy on top of this locality-based distribution, to achieve considerable energy conservation. The whole system is made to work under a standard set of memory
Modding board games into serious games: The case of Climate Policy

We argue that board games are an interesting medium for serious games, especially when the goal is to teach players about particularly complex systems. In that case, the transparency of a board game make ..."
