At present, solar energy conversion technologies face cost and scalability hurdles in the technologies required for a complete energy system. To provide a truly widespread primary energy source, solar energy must be captured, converted, and stored in a cost-effective fashion. New developments in nanotechnology, biotechnology, and the materials and physical sciences may enable step-change approa...

In this paper, we present the results from a detailed energy measurement study of different TCP variants when used in Mobile Ad hoc Network environments. More precisely, we focus on the node-level cost of the TCP protocol; also know as the computational energy cost. In fact, the computational energy consumption is the most important part of TCP energy consumption. This is already proven in prev...

Each dot represents one company as the intersection of its output (X) and its costs (Y). The solid line (OLS) represents the “Ordinary Least Squares” regression line, which defines the average or expected value of Y (costs) for each value of X (output). It is defined by the intercept, a, and the gradient, b. Without delving into the details of the technique, it amounts to “drawing a line throug...

The International Renewable Energy Agency (IRENA) is an intergovernmental organisation dedicated to renewable energy. In accordance with its Statute, IRENA's objective is to "promote the widespread and increased adoption and the sustainable use of all forms of renewable energy". This concerns all forms of energy produced from renewable sources in a sustainable manner and includes bioenergy, geo...

Due to increasingly expansion of energy consumption and also decreasing and tendency towardsending fossil energy reserves, the current energy cycle needs to use alternative energy speciallywind energy, because it’s considerably cheaper than other recycling sources. The present researchinvestigates possibility of creating wind Power Station economically at Soltanieh zone of Zanajnprovince regard...

Landauer argued that the process of erasing the information stored in a memory device incurs an energy cost in the form of a minimum amount of mechanical work. We find, however, that this energy cost can be reduced to zero by paying a cost in angular momentum or any other conserved quantity. Erasing the memory of Maxwell’s demon in this way implies that work can be extracted from a single therm...

The action potential of the unmyelinated nerve is metabolically expensive. Using the energetic cost per unit length for the biophysically modeled action potential of the squid giant axon, we analyze this cost and identify one possible optimization. The energetic cost arising from an action potential is divided into three separate components: 1) the depolarization of the rising phase; 2) the hyp...

General cost for CNC machining and the associated energy cost are set in the context of making economic and environmental improvements. This creates an incentive for manufacturing companies to investigate the energy efficiency of manufacturing processes. The paper presents a costing model, based on machining experiments. The model is accompanied with an industry based case to estimate the cost ...

My advisor made some changes to my research paper. Since it will be posted on OPENSIUC, he wanted to make some technical changes to the paper. I have already gotten this paper accepted, and the changes on this paper are minor, but necessary. iv ACKNOWLEDGEMENTS A great amount of appreciation is given to the educators in the Kinesiology graduate school departments. In particular, Dr. M. Daniel B...

We have found periodic collisionless motions for a rigid-body walking model. Unlike previous bipedal designs, this model can walk on level ground at non-infinitesimal speed with zero energy input. The model avoids collisional losses by using an internal mode of oscillation: swaying of the upper body which is coupled to the legs by springs. This avoidance of foot-strike collision losses by means...
