Recent advances in wireless sensor networks have led to many routing methods designed for energy-efficiency in wireless sensor networks. Despite that many routing methods have been proposed in USN, a single routing method cannot be energy-efficient if the environment of the ubiquitous sensor network varies. We present the controlling network access to various hosts and the services they offer, ...

Self-replication is a remarkable phenomenon in nature that has fascinated scientists for decades. In a self-replicating system, the original units are attracted to a template, which induce their binding. In equilibrium, the energy required to disassemble the newly assembled copy from the mother template is supplied by thermal energy. The possibility of optimizing self-replication was explored b...

The first triboelectric-nanogenerator (TENG)-based self-powered implantable drug-delivery system is presented. Pumping flow rates from 5.3 to 40 µL min-1 under different rotating speeds of the TENG are realized. The implantable drug-delivery system can be powered with a TENG device rotated by human hand motion. Ex vivo trans-sclera drug delivery in porcine eyes is demonstrated by utilizing the ...

Providing a constant and perpetual energy source is a key design challenge for implantable medical devices. Harvesting energy from the human body and the surrounding is one of the possible solutions. Delivering energy from outside the body through different wireless media is another feasible solution. In this monograph, we review different stateof-the-art mechanisms that do “in-body” energy har...

Powerand energy-efficiency are significant requirements in virtually all computer systems, from mobile devices to large-scale data centers. Power delivery is a process that distributes stable supply voltages to gates within an integrated circuit (IC). The design of such a delivery network is a critical task to guarantee functionality, timing, and operation reliability, and significantly affects...

.Due to limited resources of individual senor nodes, there is usually a trade-off between energy spending for packets transmissions and the appropriate level of reliability. Since link failures and packet losses are unavoidable, sensor networks may tolerate a certain level of reliability without significantly affecting packets delivery performance and data aggregation accuracy in favor of effic...

We consider nmobile agents of limited energy that are placed on a straight line and that need to collectively deliver a single piece of data from a given source point s to a given target point t on the line. Agents can move only as far as their batteries allow. They can hand over the data when they meet. In this paper we show that deciding whether the agents can deliver the data is (weakly) NP-...

The unique properties of nanomaterials related to structural stability and quantum-scale reactive properties open up a world of possibilities that could be exploited to design and to target drug delivery or create truly microscale biological sensors for veterinary applications. We developed cost-saving and solvent-free nanoemulsions. Formulated with a low-energy method, these nanoemulsions can ...

In today’s Internet, multimedia traffic accounts for the largest share of all traffic, highlighted by its volume, variety, multicast nature, and QoS constraints. Downstream towards consumers, multimedia traffic may traverse through middleboxes, undergoing additional data processing imposed by content providers and/or distributors. With the advent of Network Function Virtualization (NFV), middle...

The provision of both electrical and mechanical energy services can play a critical role in poverty alleviation for the almost two billion rural users who currently lack access to electricity. Distributed generation using diesel generators remains a common means of electricity provision for rural communities throughout the world. Due to rising fuel costs, the need to address poverty, and conseq...
