Energy efficiency is regarded as an important objective in a world of limited resources. The sustainable use of energy is necessary for the continuity of life styles that do not jeopardize the future. Nevertheless, due to poor information about the impact of human actions on the environment, it is hard to promote and warn for sustainability. This work focuses on the use of ambient intelligence ...

cold hardiness is one of the most common adaptations of insects at low temperatures. to understand the cold hardiness strategy of beet armyworm, spodoptera exigua (hübner), six temperature treatments were tested on the last instar larvae. supercooling points of treatments were not significantly different. two sugars, glucose and trehalose, as well as three polyols, myo-inositol, glycerol and so...

the effect of hydraulic retention time in a range from 1.0-5.5 days was evaluated in a laboratoryscaleanaerobic fixed bed reactor packed with a hybrid material composed of tire rubber and zeolite. underthese conditions, cod removal efficiencies varied from 28.3% to 82.1%, respectively. over the more than 6months of operation, no clogging was observed. the results obtained demonstrated that this...

the main objective of a research program, whose output is presented here, has been to estimate “ventilation coefficients”, a critical parameter in determining air pollution concentration near the surface ground which signifies the ability for natural ventilation of an air shed in an urban or rural area. relevant measured data from the city of tehran has been used to calibrate and further de...

the current study reports some interesting growth of novel in2o3 nanostructures using ambient-controlled chemical vapor deposition technique in the presence of a strongly reducing hydrazine ambient. the experiments are systematically carried out by keeping either of the carrier gas flow rate or the source temperature constant, and varying the other. for each of the depositions, the growth is st...

We consider an inspection game between an arbitrary number of polluting rms and an agency who can choose to monitor ambient pollution. We obtain an equilibrium where all rms comply with the same probability and where the inspection agency inspects all rms individually if ambient pollution exceeds an endogenous threshold. If the ne for noncompliance is high enough, the agency's costs are lower t...

We add name groups and group creation to the typed ambient calculus. Group creation is surprisingly interesting: it has the eeect of statically preventing certain communications, and can thus block the accidental or malicious escape of capabilities that is a major concern in practical systems. Moreover, ambient groups allow us to reene our earlier work on type systems for ambient mobility. We p...

We discuss the idea of ambient networking and describe our contribution to this field on providing quality of service in 802.11b wireless LANs, service discovery, and personal communication environments.

This paper proposes the use of an autonomous assistant mobile robot in order to monitor the environmental conditions of a large indoor area and develop an ambient intelligence application. The mobile robot uses single high performance embedded sensors in order to collect and geo-reference environmental information such as ambient temperature, air velocity and orientation and gas concentration. ...
