Over half of the total electricity consumption is used in buildings. Air-conditioning and electric lighting are the two main resources of electricity consumption in high rise buildings. One way to reduce electricity consumption would be to limit heat gain into buildings, therefore reduce the demand for air-conditioning during hot summer months especially in hot regions. On the other hand natura...

This study examines causal link between energy use and economic growth for five South Asian countries over period 1971-2006. Panel cointegration, ECM and FMOLS are applied for short and long run estimates. In short run unidirectional causality from per capita GDP to per capita energy consumption is found, but not vice versa. In long run one percent increase in per capita energy consumption tend...

One of the obstacles preventing the Zigbee protocol from being widely used is the excessive power consumption of Zigbee devices in low bandwidth and low power requirement applications. This paper proposes a protocol that resolves the power efficiency problem. The proposed protocol reduces the power consumption of Zigbee devices in beacon-enabled networks without increasing the time taken by Zig...

In recent years, the research in wireless sensor network has increased steadily, and many studies were focusing on reducing energy consumption of sensor nodes to extend their lifetimes. In this paper, the issue of energy consumption is investigated and two adaptive mechanisms are proposed to extend the network lifetime. This study uses high-energy-first scheme to determine cluster heads for dat...

This work describes a two-stage CMOS Voltage Ring Oscillator (VCRO) using differential delay cells are analyzed. The main aim of the paper is to increase the tuning range of the circuit and obtain a good phase noise at the cost of design complexity and power consumption. Two-stage VCRO implemented in 90 nm Technology realizes a tuning range of 53.40% and a phase noise of -156.328 dBc/Hz for a p...

Power consumption of smartphone applications is one of the major concerns because of the limited battery capacity. An application, although functionally correct, may suffer from unexpected power consumption or energy bugs (ebugs). The existence of such e-bugs is checked for programs with energy profilers although most of them are design bugs. We propose a new model-based power consumption analy...

Greenhouse gases (GHG) emissions impose major threat to global warming potential (GWP). Unfortunately manufacturing sector is one of the major sources that contribute towards the rapid increase in greenhouse gases (GHG) emissions. In manufacturing sector electric power consumption is the major driver that influences CO2 emission. Titanium alloys are widely utilized in aerospace, automotive and ...

In this simulation-based performance study, we focus on bandwidth consumption in CCN, taking into consideration the effect that in-network caching and FIBs have on this consumption, under topologies and workloads of varying characteristics. Unlike previous performance studies, we do not assume pre-populated FIBs. We focus primarily, but not exclusively, on the default CCN forwarding strategy (f...

In this paper, a data-mining approach for modeling pumps in the wastewater preliminary treatment process is discussed. Datamining algorithms are utilized to develop pump performance models based on industrial data collected at a municipal wastewater processing plant. The performance of wastewater pumps is described by two parameters, pump energy consumption and water flow rate after the pumps. ...

This paper analyzes the adjustment of consumption expenditures if the subjective mortality hazard increases after a shock. The life-cycle model with mortality risk implies an upward adjustment of consumption expenditures as a response to such a shock. I use data from the Survey of Health, Ageing and Retirement in Europe (SHARE) to test this implication. In each survey wave, the mortality hazard...
