Many project tasks and manufacturing processes consist of interdependent timerelated activities that can be represented as networks. Deciding which of these subprocesses should receive extra resources to speed up the whole network (i. e., where activity crashing should be applied) usually involves the pursuit of multiple objectives amid a lack of a priori preference information. A common decisi...

During the last decade, Cloud computing has efficiently exploited the economy of scale by providing low cost computational and storage resources over the Internet, eventually leading to consolidation of computing resources into large data centers. However, the nascent of the highly decentralized Internet of Things (IoT) technologies that cannot effectively utilize the centralized Cloud infrastr...

A novel vector field transform is proposed for gray-scale images, which is based on the electrostatic analogy. By introducing the item of gray-scale difference into the repulsion vector between image points, the diffusing vector field is obtained by the transform. Then the primitive areas can be extracted based on the diffusing vector field with a proposed area-expanding method. A new image seg...

The speedy pace of change in telecommunications and its ubiquitous presence have drastically altered the way people interact, impacting production, government, and social life. The infrastructure for providing telecommunication services must be continuously renewed, as innovative technologies emerge and drive changes by offering to bring new services to the end users. In this context, the probl...

Liquid transportation without employing a bulky power source, often observed in nature, has been an essential prerequisite for smart applications of microfluidic devices. In this report, a leaf-inspired micropump (LIM) which is composed of thermo-responsive stomata-inspired membrane (SIM) and mesophyll-inspired agarose cryogel (MAC) is proposed. The LIM provides a durable flow rate of 30 μl/h ·...

The ambitious goal of the Handbook of Nature-Inspired and Innovative Computing is to “to be a Virtual Get Together of several researchers that one could invite to attend a conference on ‘futurism’ dealing with the theme of Computing in the 21st Century.” The Handbook contains 22 chapters, written in a “workshop style,” meaning that little to no background is required from the reader except for ...

Natural products with a sulfated scaffold have emerged as antifouling agents with low or nontoxic effects to the environment. In this study 13 sulfated polyphenols were synthesized and tested for antifouling potential using the anti-settlement activity of mussel (Mytilus galloprovincialis) plantigrade post-larvae and bacterial growth inhibition towards four biofilm-forming bacterial strains. Re...

Following your need to always fulfil the inspiration to obtain everybody is now simple. Connecting to the internet is one of the short cuts to do. There are so many sources that offer and connect us to other world condition. As one of the products to see in internet, this website becomes a very available place to look for countless advances in multi objective nature inspired computing sources. ...

Rational cryptography is an emerging field which combines aspects traditionally related to security with concepts described in economic theoretical frameworks. For example, it applies game theory concepts to address security problems arising when executing cryptographic protocols. The aim is to replace the assumption of a worst–case attacker by the notion of rational agents that try to maximize...
