as there is a rapid growth both in the number of power consumers and also the limitations energy resources, it is clearly accepted that the old version of power grid must change into smart grid from head to toe. one of the most important advantages of smart grid which makes it much more exclusive rather than other typical systems is the two-way connectivity between the utility and the costumers...

municipal solid wastes (msws) vary in terms of quality and quantity, especially their toxic content. the efficient and sound disposal of msws not only needs implementing an integrated management procedure, but also performing a conservative way to reduce the impacts on resources. in the present research, after characterization of msw streams and consideration of disposal methods practiced in si...

load management and cost optimization are among the important factors in trigenerationsystems and combined cooling, heating and power (cchp) systems. in this study, an innovative cchpsystem uses a gas turbine as the prime mover and has a heat recovery steam generator (hrsg) in addition toan auxiliary boiler, electric and absorption chillers. the system is tied with the bulk electric grid; to ex...

Abstract: The introduction of uncontrollable renewable energy is having a positive impact on our health, the climate, and the economy, but it is also pushing the limits of the power system. The main reason for this is that, in any power system, the generation and consumption must match each other at all times. Thus, if we want to further introduce uncontrollable generation, we need a large abil...

Duplex and Triple Modular Redundancy (TMR) systems are used when a high-level of reliability is desired. Real-Time Systems for autonomous critical missions need such degrees of reliability, but energy consumption becomes a dominant concern when these systems are built out of high-performance processors that consume a large budget of electrical power for operation and cooling. Examples where ene...

This study describes three different data mining techniques for detecting abnormal lighting energy consumption using hourly recorded energy consumption and peak demand (maximum power) data. Two outliers’ detection methods are applied to each class and cluster for detecting abnormal consumption in the same data set. In each class and cluster with anomalous consumption the amount of variation fro...

Recently, universities are increasingly consuming energy to support various activities. A large population of staff and students in Malaysian universities has led to excessive energy consumption which directly gives an impact to the environment. The key question then ascended “How well is an energy management (EM) been practiced in universities without taking the Critical Success Factors (CSFs)...

a numerical model for two-phase debris flows is developed in this paper, on the basis of understanding of the physical characteristics of debris flows from field investigations and experiments. employing a moving coordinate, the kinetic energy equation of gravel particles in unit volume in debris flow is developed by considering the potential energy of the particles, energy from the liquid phas...

Introduction Direct energy expenses (diesel, gasoline, propane, electricity) total more than $1 billion annually for Iowa’s farmers. Day-to-day farm management techniques such as adjusting tractor gear and throttle settings, making use of front-wheel-drive, and other strategies can reduce diesel fuel consumption for row crop production and general tractor operations. This study is being conduct...

Introduction Direct energy expenses (diesel, gasoline, propane, electricity) total more than $1 billion annually for Iowa’s farmers. Day-to-day farm management techniques such as adjusting tractor gear and throttle settings, reducing tillage depths, and monitoring tractor tire inflation pressures can reduce diesel fuel consumption for row crop production. This study is being conducted over mult...
