fCDN:A Novel-Energy Efficient Content Delivery Architecture over Next Generation Systems
Authors: OZTOPRAK Kasim 
Published: October 2018

Content Delivery in
mobile networks are gaining popularity with an increasing demand by new mobile
subscriptions. Reduction of the outgoing traffic is becoming an important
issue, which is proposed to be reduced by a futuristic Content Delivery System
(fCDN) for Mobile Operators. The proposed system utilizes the idea
Device-to-Device Communication (D2D), with a dynamic resource allocation
support of SDN-NFV based systems and the locating of a content. The approach is
to use the content of a node as close as possible to a mobile user, which may
reduce the cost of communication, and power consumption while increasing the
Quality of Experience. The energy consumption can be reduced by proposed model up to 8 fold. When enabling the users to use
5G based systems, it reduces the energy consumption by a factor of 50 fold. The
simulation results demonstrate that the use of proposed method outperforms the
current state of the art systems in power consumption.
Synthesis and characterization of Ag-chalcogenide nanoparticles for possible applications in photovoltaics
Authors: Chand Subhash , Sharma Pankaj 
Published: October 2018

Abstract
Bottom-up technique has been used to synthesize Ag-chalcogenide nanoparticles. This work reports on the synthesis of Ag2Se by varying the molar ratio of capping agent and pH of the solution. The synthesized nanoparticles have been characterized in terms of structural parameters using X-ray diffraction. By this technique, various parameters such as crystallite size, dislocation density and strain of the nanoparticles were calculated. The crystallite size decreased with the increase in pH of the solution. The optical characterization was carried out by UV-Vis-NIR spectrophotometer. With the decrease in the crystallite size, a blue shift in the absorption peak of the nanoparticles was observed. These properties are suitable for energy harvesting with the help of photovoltaics.

Abstract
Present investigation is aimed to explore the single crystal growth, microhardness and third order nonlinear optical (TONLO) properties of Nd3+ doped zinc tris-thiourea sulphate (ZTS) crystal. The commercial slow solvent evaporation technique has been chosen to grow a good quality ZTS (12 mm × 0.5 mm × 0.3 mm) and Nd3+ doped ZTS (11 mm × 0.6 mm × 0.4 mm) single crystals. Vickers microhardness test has been employed to analyze the influence of Nd3+ dopant on the hardness behavior of ZTS single crystal. The TONLO effects occurring in Nd3+ doped ZTS single crystal have been evaluated by means of Z-scan technique using a He–Ne laser operating at 632.8 nm. The close and open aperture Z-scan configuration have been used to determine the nature of TONLO refraction n2 and absorption β, respectively. The magnitudes of vital TONLO parameters, such as refraction n2, absorption coefficient β, figure of merit and susceptibility χ3 of the Nd3+ doped ZTS single crystal, have been determined using Z-scan transmittance data. The n2, β, and χ3 of Nd3+ doped ZTS single crystal were found to be of the order of 10−10 cm2/W, 10−6cm/W and 10−5 esu, respectively.
Remediating functional activation in the face perception network in autism and 22q11.2 deletion syndrome
Authors: Glaser Bronwyn 
Published: October 2018

Introduction: Vis-à-Vis (VAV), an online enrichment program targeting skills that underlie social abilities (looking at the eye region of faces, emotion comprehension & recognition and visuo-spatial working memory) was administered to children and adolescents with autism spectrum disorder (ASD), 22q11.2 deletion syndrome (22q11DS)) and developmental delay (DD). Differential functional activation throughout the brain and in regions related to face processing were measured before and after remediation.
Methods: Participants with ASD (N=16), 22q11DS (N=12), and DD (N=9) completed a functional localizer task consisting of pictures of faces and tools before undertaking the 12-week VAV program (PreR). The same fMRI task was administered immediately after VAV, at post-remediation (PostR), and again three months later (Break). A group of healthy controls (N=10) was scanned, but not given VAV, to provide a baseline comparison for patients’ results. Functional neuroimaging data was analysed for category-specific brain activity.
Results: The ASD and the 22q11DS groups both showed atypical activation to faces at PreR compared to controls. Whereas activation in 22q11DS at PostR and Break resembled that of controls in bilateral superior temporal gyrus, insula, bilateral precentral gyrus, right lingual gyrus and right middle frontal cortex. Unlike the 22q11DS group, the ASD group’s activation did not resemble that of controls at PostR or Break. Significant clusters in the ASD group were limited to left insula and right lingual gyrus at PostR, and right superior frontal gyrus at Break. Nevertheless, a significant relationship between increased BOLD response between PreR and PostR in the right fusiform gyrus and improvement on the VAV games teaching participants to focus on the eyes was observed in both groups. This relationship was not present in the DD group.
Conclusions: These results support hypo-activation in response to faces in ASD and 22q11DS and differential cerebral activation in face processing networks following cognitive remediation.

The purpose of the utility of safety belt is to minimize the impact that could occur in a car accident. Safety belt consists of two main parts; i.e. transverse diagonal sash belt and lap belt that lies horizontally on the abdomen. Both parts make a form of continuous network that securing the driver. The main problem in the usage of safety belt is that many drivers ignored the function of the safety belt and did not use it. Some drivers tightened one part of the belt only, others even did not use it at all. Facing this problem, a model was designed in this research that can always remind and force the drivers to use their safety belt. Additional features were detection system for car speed and for driver’s head position. This designed device consists of several main components such as microcontrollers, limit switches, heat sensors, sound system, an accelerometer, and potentiometers. Some components were designed based on separate modules and merged into a single unit device that can always remind drivers to use safety belts correctly. Based on the results of the conducted experiments, the system can function correctly in which it always perfomed rechecking of each parameter.

¿Dos caras de la misma moneda?: una reflexión sobre la relación entre engagement y participación en medios
Authors: Bergillos Dr. Ignacio 
Published: October 2018

Este texto presenta las principales disciplinas y aproximaciones teóricas que estudian el engagement en medios y adopta una comprensión interdisciplinar del término. A través de una extensa revisión bibliográfica se trata de problematizar el engagement atendiendo a los matices que aportan otros conceptos vinculados a él, como la interactividad, la economía afectiva, el compromiso y, fundamentalmente, la participación. Se apunta finalmente a la necesidad de interpretar los complejos fenómenos comunicativos que involucran a las audiencias partiendo de la base de una relación de confianza y respeto mutuo que reconozca sus desequilibrios de poder y sus implicaciones morales y afectivas.
Engagement y Fuerzas Armadas: Una reflexión acerca del compromiso y la lealtad de lo militar con la opinión pública

Published: October 2018

El término engagement lo conocemos habitualmente como asociado a compromiso o lealtad, pero no existe un claro consenso en la definición y naturaleza del mismo, a pesar de ser ampliamente utilizado en las comunicaciones referidas al marketing y la empresa. Este artículo se aleja de esas perspectivas tradicionales para entrar en una nueva dimensión, aunque menos conocida, y que es la referida al ámbito de las Fuerzas Armadas, donde el significado del término adquiere otro bien diferente, y que ha servido para delinear las nuevas políticas del uso de la fuerza de la ONU en operaciones de ayuda humanitaria, alivio a desastres, operaciones de búsqueda y rescate; evacuación de no combatientes; apoyo militar a autoridades civiles; implementación de sanciones y embargos; operaciones de demostración de fuerza y protección de fronteras.

The methodological approach was suggested to define a rational heat load of the air conditioning system (ACS) with taking into consideration the current climatic conditions of operation. The proposed approach is based on the hypothesis of sharing the current changeable heat load on the relatively stable share as the basic one for choosing installed (designed) refrigeration capacity of the refrigeration machine, operating with high energy efficiency in nominal or similar modes, and unstable heat load, corresponding to ambient air precooling at changeable current temperatures. To prove the methodological approach to defining a rational heat load of the ACS was carried out the analysis of current values of heat loads of the refrigeration machine ACS during cooling ambient air from its changeable current temperature to the temperature of 10, 15 and 20 ºС . It is shown that due to the different rates of annular refrigeration capacity production increment to cover the current heat loads with increasing the installed refrigeration capacity of the refrigeration machine, caused by the changes in heat load according to current climatic conditions during all the year round, it is necessary to choose a such heat load on the refrigeration machine of ACS (its installed refrigeration capacity), that provides a maximum or similar annular refrigeration capacity production at relatively high rates of its increment. Therein, the value of heat load for ambient air precooling is calculated according to remained principle as the difference between the rational total heat load and its basic relatively stable share. The proposed method is useful for defining a basic installed refrigeration capacity of the refrigeration machine of ACS with the accumulation of excessive (unapplied) refrigeration capacity at lowered current heat loads on ACS and its application for ambient air precooling, that is for covering unstable heat load share on ACS

Published: October 2018

Research found out that fumaroles and solfataras are rare earth element (REE) vapor transport agents in Weh Island submarine volcano – Aceh. Shallow high resolution single channel seismic was used to map the distribution of seafloor fumaroles surrounding the submarine volcano. Samples of REE depositions were taken from Jaboi geothermal field, and mineralization zone at Pria Laot coast; as well as seafloor surrounding active fumaroles by divers. Rare earth elements (REE) were analysed using ICP – MS (inductively coupled plasma – mass spectrometry) with detection limits ranged from 0.05 to 0.1 ppm (part per million).The central part of Weh submarine volcano is the most active REE deposition. This area is build by normal faults and grabens oriented north – south of open character which acted as channel for hydrothermal fluids reaching seafloor surface.Some REE abundances such as La, Ce, Pr, and Nd due to its location in the central of hydrothermal activity. This proximity explains such abundances of this andesitic component sample of agglomerate.
