Molecular communication is a promising paradigm to implement nanonetworks, the interconnection of nanomachines. Catalytic nanomotors constitute one of the techniques that have been proposed for medium-range molecular communications. This paper presents a physical channel characterization that shows how nanomachines communicate using catalytic nanomotors as information carriers. Quantitative res...

The paper presents a brief survey of the Medium Access Control (MAC) protocols for Wireless Sensor Networks (WSN). It describes pros and cons of some known solutions of the MAC protocols with emphasis on his energy efficiency. The main goal in WSN is prolonging the lifetime of the sensor node, that is usually battery powered and can thus be achieved by designing energy-efficient MAC protocols. ...

We use machine learning for designing a medium frequency trading strategy for a portfolio of 5 year and 10 year US Treasury note futures. We formulate this as a classification problem where we predict the weekly direction of movement of the portfolio using features extracted from a deep belief network trained on technical indicators of the portfolio constituents. The experimentation shows that ...

In wireless sensor networks (WSN), the nodes are low powered devices and hence designing a low power WSN is highly important for getting longer lifetime. In this paper, we have discussed several aspects of design and operations of low power WSN. We have reviewed and critically analysed different design issues such as dynamic power management, ultra-low power node design, duty cycle assignment a...

Executive Summary • Better decisions on Countries at Risk of Instability (CRI) require strengthening of the full decision support system not just the components of risk assessment and early warning. Designing effective responses to CRI requires risk assessments over the short (1-2 years), medium (5-6 years) and long (10-15 years) term to guide immediate action, and the resource allocation and i...

The integration of the Internet and TV (InternetTV) is a powerful medium for delivery of instruction to learners. However, the instruction has to be designed to cater to the needs and characteristics of the learners. Proper design and analysis strategies must be followed when designing instruction for InternetTV. More research is needed on the integration of the different messages on InternetTV...

Local conversations online are an important means of building awareness and increasing participation amongst citizens. However, most local websites are restricted to using forums or collaborative blogs as the medium of conversation. We are designing ‘Colloki’, a local conversation system that aims to utilize a set of social and organizational features for a more effective conversational environ...

As we stated before FIP is one of the fieldbus systems, these systems usually consist of many control loops that communicate and interact with each other via single network channel (i.e. cable). Here we will try to develop a scheduling policy that will guarantee a fair distribution of this medium between these control loops, and at the same time takes into account several important parameters i...

In past decades, considerable effort has been devoted to the phenomenon of wave-induced liquefaction, because it is one of the most important factors for analysing the seabed and designing marine structures. As waves propagate and fluctuate over the ocean surface, energy is carried within the medium of the water particles. This energy could be transmitted into the seabed, which results in the r...

In this paper we address the problem of designing error protection mechanisms for Medium Access Control (MAC) protocols with Quality of Service (QoS) constraints. The analysis focuses on the typical case of Wireless Local Area Networks (WLANs) which are characterized by slowly time-varying channels. An analytical approach to efficient management of transmission, formalized as an optimization pr...
