The first objective of Join-MED is to create a sustainable network of ICT research organisations in the Mediterranean Partner Countries (MPC) and Europe, reinforcing the Research Cooperation between these two regions on a wider scale. To achieve this, Join-MED will organise a series of networking events in the MPC that will bring researchers from different MPC and EU together. Furthermore, it will support the creation of institutionalised networks on a cross-regional basis, suggesting appropriate methodologies for accomplishing this. To support all networking activities Join-MED will develop an interactive web-based directory of research organisations from both regions, the MPC and EU. To help unfold the potential of the research capacity across the MPC, where is still driven by national initiatives with very little cross-regional co-operation, Join-MED will promote closer research co-operation across the region. This will achieved by moving from country-focused networking events to cross-regional ones. The second objective of Join-MED is to support the Information Society policy dialogue and the co-ordination of national policies on international co-operation in the MPC. This will be achieved by for-mulating a harmonised MPC ICT policy and through an open dialogue, among the MPC as well as with Europe. Join-MED will establish close links with existing and emerging co-operation projects addressing the MPC, in particular the NCP Network, to exploit synergies with the different objectives they pursue, maximise impact and contribute to the definition of co-operation strategies.

EUMEDGRID-Support aims at reinforcing the relevance of European e-Infrastructures in the Mediterranean and Middle-east regions. The project will build on the results obtained by EUMEDCONNECT/ EUMEDCONNECT2 and the preceding project EUMEDGRID, which successfully deployed a research and education network and a pilot Grid infrastructure, respectively, presently covering almost all the Mediterranean Area. An agreement has been signed among the EUMEDGRID partners to keep open, to the best of their capabilities, the existing Infrastructure and EUMEDGRID-Support wants, not only to consolidate and expand it, but also to make a step forward towards its sustainability.\nThe overarching objective of EUMEDGRID-Support is to retain the European and Mediterranean country dialogue achieved in the past as well as to increase stakeholders and community awareness on the fundamental importance of e-Infrastructures in the Mediterranean and on their sustainability.\nThe project will use the consolidated schema of a two-fold approach: A bottom-up, raising the awareness of researchers, students and technical personnel, which will exploit the usage of e-Infrastructures in their work and appreciate their value, and a top-down approach at the high policy-level highlighting the benefits and justifying the necessity of e-Infrastructures to influential stakeholders in order to push for a long term stability and sustainability of such e-Infrastructures.

The geometric factor for the resistivity measurement of a thin disk, given in a previous work as a slowly converging series, is reworked and reduced to a simple form. On the other hand, the correction, when contacts are assumed of vanishing width, is also calculated analytically and discussed. It is found not to exceed 1.5% when λ, the ratio of distances between potential contacts and current contacts, is equal to 1. Our new expression is applied to determine the room temperature resistivity of two metallic thin disks. © 2010 Elsevier Ltd. All rights reserved.

The expression of the transverse resistance for an ohmic parallelepipedic layered conductor, measured with strip contacts, extended along its width, is a slowly convergent series. This series is reworked and transformed to the sum of an analytical part and an exponentially convergent series, which reduces considerably the number of terms needed for the numerical evaluation. In addition, an asymptotic formula is obtained, valid for Γ < 2, Γ is the effective anisotropy. This formula is used to determine the room temperature resistivity anisotropy of two small Γ layered superconductors, which are 2H-NbSe2 and 2H-TaSe2. © 2010 Elsevier Ltd. All rights reserved.

A localization algorithm based on cell identification (Cell-ID) information is proposed. Instead of building the localization decisions only on the serving base station, all the detected Cell-IDs (serving or nonserving) by the mobile station are utilized. The statistical modeling of user motion and the measurements are done via a hidden Markov model (HMM), and the localization decisions are made with maximum a posteriori estimation criterion using the posterior probabilities from an HMM filter. The results are observed and compared with standard alternatives on an example whose data were collected from a worldwide interoperability for microwave access network in a challenging urban area in the Brussels capitol city. © 2011 IEEE.

For the middle latitudes (mid-latitude) zone (latitudes between 23.45°N and 43.45°N and between 23.45°S and 43.45°S), as rules of thumb first solar collector should be orientated toward Equator and second it should have a latitude tilt value; however are these statements valid all over the year? The present work focuses on presenting an algorithm for determining the optimum tilt angle over mid-latitude zone and for any collector azimuth angle. Moreover, two simple approximate equations are proposed for predicting daily optimum tilt angle and optimum tilt angle for any number of consecutive months. The present algorithm was applied at different latitudes where data are available. The different yearly possible energy gains in relation that received by a horizontal surface were calculated. It is found that the yearly daily average energy gain for daily, monthly, seasonally and half-yearly adjustments are approximately constant. For the latitude of 43.45°N it reaches 1.7 times that of horizontal surface. So, it is sufficient from practical point of view to adjust the solar collector tilt angle twice a year: once on 22/3 and the other on 22/9. Moreover, the first rule of thumb is valid however the second one is not applicable for a large number of consecutive days in the year. © 2016 Elsevier Ltd


Bari (2000) proposed a method to determine the optimum slope angle and orientation of solar collectors for different periods of operation (1-365 days) at any position in the Malaysian territory. He mentioned that the optimum slope angle as well as the orientation can be found conveniently and accurately by this method. Later on he applied this method to calculate the optimum tilt angle over Thailand and Philippines. The present comments are focused on these statements and the novelty of this work. © 2016 Elsevier Ltd. All rights reserved.

The preparation of nonwoven mats of electrospun poly(lactic acid)/polyaniline (PANI) blend nanofibers faces some critical challenges that will be addressed in the present work. The challenges are in achieving high and adjustable content of PANI while keeping the spinnable solution nonagglomerated with no need to further filtration that might lead to wrong estimation of PANI content in the mat. We report an unprecedented content of 40% wt of PANI that is achieved using a new two-step procedure. It is based on: (1) the preparation of the spinnable solution from a friable nonagglomerated and readily dispersible PANI: p-TSA powder and (2) the use of an optimized mixture of m-cresol/dichloromethane. The obtained nanofiber mats are characterized by FTIR and UV-vis spectroscopy. The morphology and the thermal stability of the nanofibers are investigated by scanning electron microscopy (SEM) and differential scanning calorimetry (DSC). The amorphous structure of the nanofibers is verified using XRD measurements. The DC-conductivity of these blend nanofibers is found to be far larger than the published DC-conductivity values for blend nanofibers of PANI with PLLA or with other polymers. This is attributed to the high content of PANI in the blend and to the role played by m-cresol as a secondary dopant. The investigation of the aging effect on the DC-conductivity reveals an exponential decrease with a characteristic time of τ≈13 weeks. The electrical impedance spectroscopy (EIS) shows a pure ohmic behavior of the blend mat. © 2016 Wiley Periodicals, Inc.


Stanciu and Stanciu [1] mentioned that when using the Hottel and Woertz model for estimating the incident solar radiation, the daily optimum tilt angle Bopt,d for a flat plate collector could be computed as simplest as Bopt,d = L - δ function on the latitude, L, and solar declination, δ, with emphasizing that this equation is applicable all over the world from 0° latitude to 80° and the novelty of their work consists in finding this global optimum instead of "local" ones for which monthly adjustment is required. The present comments are focused on these statements and the novelty of this work. ©2015 Elsevier Ltd. All rights reserved.

Using wet chemistry method, we have synthesized silver nanoparticles, with sizes going from 16 nm to 47 nm. Silver nanoparticles are formed in aqueous solution of silver nitrate, with dextrose as reducing agent; and polyvinylpyrrolidone (PVP)as a stabilizer. In this study we use urea as an additive to produce intermediates that slow the transformation of silver ions into silver by the reducing agent. We obtain silver colloids of small sizes and a narrow distribution using only a small amount of protective agent while maintaining high conversion rates at reasonable silver concentrations at the same time.
