Abstract:

Ambient energy harvesting has attracted significant attention over the last years for applications such as wireless sensors, implantable devices, health monitoring systems, and wearable devices. The methods of vibration-to-electric energy conversion can be included in the following categories: electromagnetic, electrostatic, and piezoelectric. Among various techniques of vibration-based energy harvesting, piezoelectric transduction method has received the most attention due to the large power density of the piezoelectric material and its simple architectures. In contrast to electromagnetic ene

Abstract:

Improvements in embedded electronics which have effectively reduced power consumption requirements as well as advancements in IC technology allowing utilization of low power inputs have made Energy Harvesting a popular power solution for low power applications such as WSNs. In many implementation areas, we can see solar, thermal, and vibration energy harvesting techniques have taken the role of batteries as power source. Now that Energy Harvesting is a popular and considerably mature technology, with proper design and installation, any object exposing energy has the ability to be promoted as a

Abstract:

Harvesting and dewatering can account for up to 30% of the overall cost of production of usable microalgae biomass for the biotechnology and bioenergy sectors. Harvesting is particularly challenging due to the small amount of algal biomass produced relative to water volume. This process exacts high energy and cost demands and therefore limits further expansion in the microalgae biomass industry. Foam fractionation has potential to deliver a low cost, low energy harvesting solution. Microalgae cells adsorb to the surface of a stream of fine air bubbles, which then rise up a closed column, disch

Abstract:

With regional rainfall of good volume and quality, and growing demand on the urban water supply in South East Queensland, rainwater harvesting (RH) is increasingly considered as a potential household supplement to the mains supply. RH is attractive because it offers households access to control over an augmented water supply. It also constitutes a form of demand management on the mains water supply and offers beneficial externalities to the environment. The Australian Bureau of Statistics (ABS) (Cat No. 4602.0: 2005) reported that household adoption of RH systems was limited to fewer than eigh

The aim for this thesis was to investigate if harvesting of ambient radio waves could be a viable source of energy and where and when it can be used. A survey of the signal strengths at different locations in Uppsala, Sweden was performed which showed that the cellular frequency bands were the ones that carried the most energy. One circuit was manufactured and two more were simulated, together with the circuitry required to measure and display how much energy that was being harvested. The design was tested at the same locations as the survey of the signal strength was conducted at. The maximum

With the increasing population the energy consumption has increased which makes the requirement for clean energy important, now more than ever. The transport sector is one of the biggest contributors to this consumption and should therefore be taken into consideration when looking for environmentally friendly solutions.

For a passenger car traveling at 13.4 m/s it is found that 200 W worth of energy is lost in the vehicles suspension system. The purpose of this work is to analyze and eval

Cementitious building components, although widely used in low-income countries, are too expensive for many applications related to low-income housing.

Improved designs, to achieve better material economy. 3. Change of production environment, from on-site to component prefabrication followed by transport to site.

Abstract:

La très faible consommation dans les appareilles modernesest le facteur-clé pour les capteurs alimentée par une source d’énergierécupérée. La réduction du budget de puissance peut être atteinte grâceà différents techniques lié à trois niveaux d’abstraction : transistor, circuitet système. L’objet de cette thèse est l’analyse et la conception descircuits à très faible consommation pour des réseaux des capteurs sansfils. A’ régulateur de tension et an émetteur RF ont été examiné. Lepremier est le circuit principal pour la gestion de puissance ; il agitcomme interface entre le transducteur et les

Abstract:

Aujourd’hui, les communications mobiles sans fil sont en pleine croissance, en raison du grand nombre d’appareils connectés, ce qui augmente considérablement la demande de gros volumes de données, nécessitant des calculs intensifs et entraînant une forte consommation d’énergie. Toutefois, cette expansion des services sans fil est encore entravée par les limitations des terminaux mobiles, en termes de capacité de traitement, de stockage et d’énergie. Récemment, le Mobile Edge Computing (MEC) et la récupération d’énergie (EH) ont été proposés comme des technologies prometteuses pour prolonger la

Abstract:

This work is dedicated to principles of energy harvesting or scavenging from free energy around us. Energy harvesting principles are described in the first part. Following chapter is devoted to description of piezoelectricity and piezoelectric materials. Next part researches already reported results on piezoelectric energy harvesters. Following chapter shows simulations on designed structures in ANSYS® Workbench. Next the fabrication of the structures is described. Measurement are made regarding to maximum generated power.

Abstract:

Les progrès technologiques accomplis durant ces dernières décennies dans les domaines des microsystèmes et des radiocommunications nous permettent de réaliser des composants communicants miniaturisés à faible coût afin de constituer des réseaux de capteurs sans fil. Typiquement, chacun de ces composants intègre une ou plusieurs unités de mesures (capteur), une unité de traitement de données, une unité de communication radio et une batterie. De ce fait, un nouveau domaine de recherche s’est créé pour étudier le déploiement de ces réseaux afin d’offrir des solutions de surveillance et de contrôl

Abstract:

Energy harvesting is a promising and evolving field of research capable of supplying power to systems in a broad range of applications. In particular, the ability to gather energy directly from the environment without human intervention makes energy harvesting an excellent option for powering autonomous sensors in remote or hazardous locations. This dissertation examines the possibility of using energy harvesting in new and innovative ways to power wireless sensor nodes placed in the substructures of highway bridges for structural health monitoring. Estimates for power requirements are establ

Abstract:

At the rate in which India population is increasing, it is said that India will surely replace China from its number 1 position of most densely populated country of the world after 20-30. These will lead to high rate of consumption of most valuable natural resource „Water‟ resulting in augmentation of pressures on the permitted freshwater resources. Ancient method of damming river and transporting water to urban area has its own issues of eternal troubles of social and political. In order to conserve and meet our daily demand of water requirement, we need to think for alternative cost effectiv

Abstract:

Shrimp harvesting techniques playa major role in the efficient and profitable operation of traditional shrimp farms. It is a labour intensive operation. However, there is a paucity of information of harvesting techniques in the traditional sector of shrimp culture in India. Problems are encountered in harvesting cultured shrimps especially in the farms, which are not fully drainable. Various harvesting techniques such as sluice net operation, cast netting, gill netting, complete draining of the farms and hand picking are deployed at different stages to harvest the shrimp from the farms.
