Energy management and consumer models in smart grid systems
Demand management activity for smart networks aims to reduce or normalize energy consumption by providing consumers with dynamic prices or incentives in the form of monetary or non-monetary rewards. Some demand management techniques have been offered, however, a major issue in their design and their operation is recruitment of users.
Improvement of fuel cell anodes using sono electrochemical methods
(Innovative Fuel Cell Enhancement) Particles of the colloidal solution can be formed on the substrate powder of the particle. In the case of platinum is used a different approach. Black carbon has been suspended from the precursor solution resulting in the synthesis of platinum particles to exist in the in situ decoration of carbon black particles. In addition to the TEM microscope, the use of dynamic light diffusion (DLS) was very useful in determining the duration of the palmon. Oles except for the dice lessons of the decoration were determined based on literature. The ultimate goal was to determine a method that could provide material with suitable loads so that it could use experimental fuel cell assemblies. In addition, the decorative powders introduced in this study were sent and tested for temperature reduction and programmable oxidation (TPR & TPO). Therefore, synthesized materials have proven to be able to improve the process of liquid reform of methane, the main component of natural gas
The All-optical imaging system allows for real time, on line imaging without having to adjust or align the system. The system?s modified lens provides a high depth of field, namely, an extended region within which the image is kept in focus without the need for an auto focus mechanism or a post-processing step.
With the multi-domain network operating system it becomes easier to introduce new routing features simply as applications that run on top and to improve the present Internet routing system. Outsourcing enables economies of scale and therefore provides an opportunity for reducing network management costs. This way, NetVolution provides both economical and technical incentives for evolving the Internet routing system, while it retains backwards compatibility with the present status quo. The key outcomes of NetVolution will be a multi-domain network operating system, applications that will run on top and will improve the security and reliability of the Internet routing system, and a new economic model for the optimization of the operation of networks.
The novel idea behind NetVolution is to migrate routing intelligence from network nodes (e.g., routers and switches), which are currently closed systems that cannot accommodate innovation, towards a new type of outsourcing service provider that operates a multi-domain network operating system and uses it to optimize the operation of the networks of its clients.

The research results presented in this paper consider the use of a wireless acoustic sensor network for estimating the locations of multiple sound sources, e.g., multiple speakers, that are active in an environment. Each sensor of such network consists of multiple microphones and can perform locally limited signal processing and communication functionalities. Each sensor estimates some local information about the active sound sources and transmits it to a central node that performs the localization task. The localization method proposed in this paper can accurately estimate the locations of up to three simultaneous sound sources, while it does not require the signals from different sensors to be synchronized, alleviating an important constraint for real-life applications.
novel two stages approach to redistribute the energy of the speech signal over time and frequency in such a way so to protect the most valuable information of speech in noise. Firstly, the redistribution of signal energy over frequency respects observations of what human talkers do when faced with noise or when attempting to speak clearly, for example, to listeners with hearing impairment. At the second stage, the algorithm protects areas of speech which are vulnerable to noise by boosting their energy, while it reduces the energy from the most sonorant parts of speech (these parts are already well protected from noise). In this way the global energy of the signal before and after manipulation remains the same. However, the manipulated signal sounds by far more intelligible than the original non-manipulated signal.
image analysis framework for the early assessment of hypertensive retinopathy signs
The proposed method employs an image segmentation algorithm, along with pre-processing and skeletonization techniques, in order to extract an accurate representation of the vessel on the retina. All functions are grouped into an integrated graphical user interface, which helps the clinician to ergonomically measure, and statistical measurements based on medical protocols or measurements in each selected area of interest. In addition, the system provides methods for editing vessel representation in order to recover from the possible classification of segmentation. These steps are integrated into a clinical application capable of supporting vascular risk stratification in people with hypertension, currently clinically tested at the Hippocrates Hospital at the University of Aristotle in Thessaloniki.
Steel pipes buried with flexible joints under malfunctions
Oil and gas pipelines are buried with flexible joints and data tearing tectonic fracture and formulating practical design guidelines. Blue-type flexible joints are offered as an innovative mitigating measure against the consequences of geological replicas and they introduced the oil pipeline near its fault to absorb strains through the relative rotation of adjacent pipe segments, which then remained barely undeformed and consequently tamped.
