Authors: Alasi Tomy Satria , Allwine Allwine 
Published: October 2019

String matcing is a technique of reading in this computer just as humans do from left to right or from right to left in several languages the faster someone reads more information is obtained. Adaptation of supervisors is important for academics and has been applied throughout the academic. However, if there are many students, it will certainly make it difficult for academics, the reason why it is necessary to adjust the supervisor so that the lecturers' research field can really be applied to students so that the supervisors provide guidance to students to gain broader knowledge due to the field of study. Besides that, the facilities are generally used so far using manuals requires a new information system for academics so as not to drain the mind and energy The adjustment of the thesis supervisor is designed to facilitate the academic, students and lecturers to be faster. The algorithm used in this system is to use the function of pulling information using string matching. Boyer more algorithm is reading a text from many texts and taking the bottom line or key of the text as information points. If later the adjustment of supervisors processes large data and is used continuously, this system really facilitates the academic parties to be integrated by utilizing fast and smart data, so that it only needs to develop the existing academic information system.

Importance of Shock Compression in Enhancing ICME’s Geoeffectiveness

Published: October 2019

Abstract
Shock embedded interplanetary coronal mass ejections (ICMEs) are of great interest in the solar and heliosphere physics community due to their high potential to cause intense geomagnetic storms. In this work, 18 moderate to intense geomagnetic storms caused by shock-ICME complex structures are analyzed in order to show the importance of shock compression in enhancing ICMEs’ geoeffectiveness. Based on the characteristics of the shocks inside ICMEs, including the shock velocity, shock normal direction, and the density compression ratio, we recover the shocked part in the ICME to the uncompressed state by using a recovery model developed by Wang et al. according to the Rankine–Hugoniot relationship. Comparing the observational data and the recovered parameters, we find that the maximum southward magnetic field in the ICME is doubled and the dawn–dusk electric field is increased 2.2 times due to the shock compression. Then, the parameters of the observed and recovered solar wind and magnetic field are, respectively, introduced into various Dst prediction models. The prediction results show that, on average, the shock compression can enhance the intensity of the geomagnetic storm by a factor of 1.4. Without shock compression, the geoeffectiveness of these ICMEs would be markedly reduced. Moreover, there is a significant correlation between the shock density compression ratio and the shock’s capacity of strengthening geomagnetic storms. The larger the shock density compression ratio is, the more obvious Dst index decrease is caused.

Abstract
The origin of the star-forming main sequence (SFMS; i.e., the relation between star formation rate and stellar mass, globally or on kpc scales) remains a hotly debated topic in galaxy evolution. Using the ALMA-MaNGA QUEnching and STar formation (ALMaQUEST) survey, we show that for star-forming spaxels in the main-sequence galaxies, the three local quantities, star formation rate surface density (ΣSFR), stellar mass surface density (Σ*), and the H2 mass surface density (

) are strongly correlated with one another and form a 3D linear (in log) relation with dispersion. In addition to the two well-known scaling relations, the resolved SFMS (ΣSFR versus Σ*) and the Schmidt–Kennicutt (SK) relation (ΣSFR versus

), there is a third scaling relation between

and Σ*, which we refer to as the molecular gas main sequence (MGMS). The latter indicates that either the local gas mass traces the gravitational potential set by the local stellar mass or both quantities follow the underlying total mass distributions. The scatter of the resolved SFMS (σ ∼ 0.25 dex) is the largest compared to those of the SK and MGMS relations (σ ∼ 0.2 dex). A Pearson correlation test also indicates that the SK and MGMS relations are more strongly correlated than the resolved SFMS. Our result suggests a scenario in which the resolved SFMS is the least physically fundamental and is the consequence of the combination of the SK and the MGMS relations.

Published: October 2019

PURPOSE:
To compare the outcomes of intracorneal ring segments (ICRS) implantation in keratoconic eyes with a similar tomographic pattern, using two different manufacturers' nomograms for surgical planning.

METHODS:
ICRS were implanted alternately in patients with the same tomographic pattern of keratoconus divided into two groups according to the surgical planning proposed by the ICRS manufacturers (Keraring, Mediphacos, Belo Horizonte, Brazil, and Ferrara Ring, AJL Ophthalmics, Vitoria, Spain). Visual, refractive, keratometric, corneal aberrometry, and optical quality changes were evaluated during a 6-month follow-up. Corneal and manifest refractive astigmatic changes were also analyzed using the double-angle polar plot and the Alpins vectorial method through the following components: target induced astigmatism, surgically induced astigmatism, difference vector, correction index, angle of error, index of success, flattening effect, and torque.

RESULTS:

After ICRS implantation, both groups showed significant improvement (
P
< .05) in visual and keratometric data. Corneal aberrometric changes and optical quality improvement were also statistically significant in both groups, except for trefoil (
P
> .05 in all intervals). The Alpins method analysis showed a better performance in the Keraring group, but with no statistically significant difference between groups (
P
> .05). Comparison between groups showed a statistically significant difference only in tomographic astigmatism in double-angle polar plot analysis (
P
= .03), with more significant improvement in the Keraring group.

CONCLUSIONS:
Both manufacturers' nomograms resulted in statistically significant improvement in most of the parameters analyzed, with greater correction of corneal tomographic astigmatism in the group operated on according to the spherical equivalent/tomographic astigmatism nomogram.

Published: October 2019

PURPOSE:
To analyze residual refractive error, ocular aberrations, and visual acuity (VA) during accommodation simultaneously with ocular aberrometry in eyes after laser-assisted in situ keratomileusis (LASIK), small incision lenticule extraction (SMILE), and transepithelial photorefractive keratectomy (TransPRK).

METHODS:
Ocular aberrometry (Tracey Technologies, Houston, TX) was performed 3 months after LASIK (n = 95), SMILE (n = 73), and TransPRK (n = 35). While measuring the aberrations, VA was measured at distance (20 ft), intermediate (60 cm), and near (40 cm) targets. The examinations were done monocularly. A parallel group of age-matched normal eyes (n = 50) with 20/20 Snellen distance VA also underwent aberrometry.

RESULTS:

Distribution of residual spherical error of LASIK eyes matched the normal eyes the best, followed by SMILE and TransPRK. However, the distribution of cylindrical error of the SMILE eyes was distinctly different from the rest (
P
< .05). The SMILE eyes tended to be undercorrected by approximately 0.25 diopters (D) on average at all reading targets compared to LASIK eyes (
P
< .05). The undercorrection was greater when the magnitude of the preoperative cylinder exceeded 0.75 D (
P
< .05). The VA of LASIK and SMILE eyes was similar to normal eyes at all targets, but the TransPRK eyes were marginally inferior (
P
< .05). Only the ocular defocus changed differentially between the study groups during accommodation and the magnitude of change was least for TransPRK eyes (
P
< .05). However, postoperative near and intermediate accommodation of LASIK eyes were similar to normal eyes, followed by SMILE eyes and then TransPRK eyes.

CONCLUSIONS:
The refractive and aberrometric status of the LASIK eyes was closest to the normal eyes. The SMILE procedure may benefit from slight overcorrection of the preoperative refractive cylinder.

Microwave-vacuum drying is superior to other methods in terms of dried products' structure, flavour, colour and biological active compounds contents. But applications of such a methods seems to be much wider: drying of fruits and vegetables for consumption, drying of herbs for extraction of valuable biological compounds, for modification of seed structure (sunflowers seeds, pumpkin seeds), for pasteurisation etc. A universal system was designed for testing such processes in laboratory scale and several industrial scale system have been developed. Process of thermal treatment can be carried out with plastic drum installed inside of multi-mode microwave cavity and cavity which is connected by microwave line with reflectometer and circulator - to microwave generator. In laboratory unit generator 2.45 GHz with controlled power (from 50W to 800W) was applied. System was equipped with vacuum pump with pressure control and is controlled by computer. Most important technical parameters, like: microwave power, time of treatment, pressure inside of drum, temperature of steam – are controlled and recorded. Laboratory scale unit is shown below. Basing on laboratory scale test several technologies in industrial scale was developed. Industrial scale unit equipped with 8 generators of 3 kW (2.45 GHz) was constructed and for last 8 years has been successfully used for “production” of crispy chips which are now popular in Polish marked. Exemplary industrial scale installation is shown in photo below. Multi – drum microwave drier. Two cavity microwave industrial drier Another system for modification od seed is now constructed – ordered by big industrial producer of batons and sweet snacks. Process will be carried our inside of dielectric drum in low pressure and reactor will be equipped with 8 generators of 3 kW (2.45 GHz). Treatment time will be reduced to 3-4 minutes and next material (seeds) will be cooled down. Last project which now realized is connected with drying of wood flour applied in composite material production. System will work continuously with two airlocks and with dielectric drum and will be connected with 4 microwave generators (3 kW, 2.45 GHz). In next step planed installation will be equipped with microwave high power generator ca. 60 kW with frequency 915 MHz.

The aim of the study is to optimize an existing microwave powered remote plasma source (RPS) with respect to the etching rate and gas temperature and to simplify the setup to save production costs. The RPS, which is shown in figure 1, is a low-pressure plasma source where the plasma is generated and exists mainly in the chamber of the source. Only radicals migrate out of the RPS. This is one important feature, that the plasma source is used for etching processes when ion bombardment and high thermal strain of the substrate must be prevented. The etching process is a chemical process, where the radicals react with the substrate surface atoms forming gaseous molecules. The benefit is a damage-free, dry and clean substrate surface. To achieve these goals, a FEM-based model of the RPS has been developed to investigate the microwave distribution and the microwave coupling into the plasma chamber, as well as the plasma itself. In this paper different examples of FEM based microwave simulations by different conditions and their experimental validations will be presented. To compare the calculated electric field distribution in the RPS with the real field distribution, PMMA-substrates were placed inside the plasma chamber of the source. They are heated up by the electric field and evaluated with an infrared camera and liquid crystal sheets. Both the measured and the calculated field distribution show a very good conformity. When the electric field is high enough in the plasma chamber the plasma ignites, the electron density and thus the permittivity and the conductivity increase, which changes again the electric field distribution. For this purpose, the FEM-model has been extended by the Drude model1. The model considers the equation of motion with a damping term for the electrons, leading to an expression for the conductivity. Results for various electron densities as well as their corresponding electric field distributions are presented and compared with optical measurements. Fig. 1. The figure shows the scheme of the RPS with its main components and functions.

The proper use of microwave heating can significantly increase the production cycle time and energy efficiency in industrial heating processes compared to conventional heating methods. The main challenge of this technique is to improve the temperature uniformity in the product exposed to standing waves inside the microwave oven. In opposite to the magnetron, solid-state amplifiers (SSA) offer the possibility to increase the homogeneity by changing the amplitude, frequency and phase with the help of intelligent control methods [1]. In this work, the variation of the frequency and the amplitude of the SSA is considered. The multimode microwave oven used in the experiment has an industrial size of 535 mm x 510 mm x 395 mm (Figure 1). The SSA was operated in the frequency range from 2.4 GHz to 2.5 GHz. It consisted of a new 300 W solid state microwave source from HBH microwave GmbH, Germany. An antenna system was developed based on numerical simulation with CST Microwave Studio. The positions of four loop antennas were optimized to excite at least 90 % of the possible 32 eigenmodes [2] of the unloaded cavity. At the roof of the cavity, an IR camera was installed to observe the temperature distribution of the load during heating. A sheet of paper was used as the thermal load. It was placed on a PTFE plate as a sample holder. Figure 1 exemplary illustrates the comparison of the simulated power distribution with the measured temperature distribution for two representative eigenmodes. As can be expected from the figures, an optimized combination of different modes will lead to a significantly improved temperature uniformity in the material. Latest results obtained with different type of loads will be presented.
A COMPARATIVE STUDY OF MICROWAVE AND BARRIER DISCHARGE PLASMA FOR THE REGENERATION OF SPENT ZEOLITE CATALYSTS

Due to their acid characteristics and pore structure, which can induce high product selectivity; zeolite catalysts are used extensively in industry to catalyse reactions involving hydrocarbons. However, these catalysts can suffer from deactivation due to cracking reactions that result in the deposition of carbon leading to poisoning of the acid sites and blocking of the pores [1]. Depending upon the reaction and the particular catalyst involved this deactivation may take place over several months or even years but in some cases occurs in minutes. Therefore, zeolite catalysts are frequently reactivated / regenerated. This generally involves a thermal treatment involving air which results in oxidation of the carbon [2]. However, the oxidation of carbon is highly exothermic, and if not carefully controlled, results in the generation of exceedingly high localized temperatures which can destroy the zeolite structure and result in subsequent loss of catalyst activity. More conservative thermal treatments can result in incomplete regeneration and again a catalyst displaying inferior activity. This paper explores the use of non-thermal plasma which had been either generated using microwaves or via a barrier discharge to regenerate spent zeolite catalysts. The catalyst, H-mordenite, was tested for the disproportionation of toluene (Figure 1) using conventional heating. The spent catalyst was then regenerated using a plasma or conventional thermal treatment before having its activity re-evaluated for the toluene disproportionation reaction as previous. Fig. 1. Reaction Scheme for Toluene Disproportionation. Interestingly, not only is plasma regeneration highly effective but also catalysts can be regenerated in greatly reduced times. There is an additional advantage in that plasma regeneration can impart physical properties that result in a zeolite that is resistant to further deactivation. However, the results are highly dependent upon the experimental conditions involved for plasma regeneration. References Wu J, Leu L., Appl. Catal., 1983; 7:283-294. M. Guisnet and P.

Voces de la ausencia/poética de la memoria en la obra Evidencias (2010) de Norberto Puzzolo, Museo de la Memoria, Rosario, Argentina. Sonido, silencio e imagen durante la dictadura argentina (1976-1983)
Authors: Alcino Valeria Fabiana 
Published: October 2019

Este trabajo se propone analizar los diversos planos puestos en relación a partir del sonido y la visualidad con las poéticas de la memoria a partir de la instalación Evidencias (2010) del artista argentino Norberto Puzzolo (Rosario,1943).La obra trata una doble problemática.Por una parte, expone los trágicos hechos de apropiación de niños, hijos de detenidos desaparecidos por el terrorismo de Estado argentino entre 1976 y 1983. Por otro lado, muestra la ardua búsqueda de las Abuelas de Plaza de Mayo y la restitución de la identidad a sus nietos.En la instalación de Puzzolo, el sonido se ubica como una evocación del pasado en tanto que el aspecto visual instala el tiempo presente y futuro. En esta unión de poéticas y temporalidades, emerge el interrogante del ser social nacional. El artista ha dejado los espacios vacíos para que sea la voluntad de la sociedad la que cierre esta obra.Evidencias, es un site specific concebido para el Museo de la Memoria de Rosario, Provincia de Santa Fe, Argentina. Asimismo, es una obra en progreso, en constante cambio a medida que los hallazgos de las identidades de los nietos desaparecidos se incorporan a la composición.Desde este punto, se intenta abordar la relación entre la materialidad de la obra visual y la invisibidad del sonido. La dimensión sonora como medio evocativo de múltiples temporalidades: pasado/presente; pasado/futuro; presente/futuro. Pensar el sonido como un signo de presencia/ausencia en esas temporalidades, como signo de aquello que en un tiempo venidero podrá –o no- estar presente. La dimensión histórica/política y política/social enfrentando la tensión entre memoria/olvido, resulta central en este abordaje. La pregunta sobre cómo vamos a reconstruir nuestro pasado reciente se pone en evidencia en el proceso de ir completando la obra. El desafío al que nos enfrenta como sociedad es la incógnita de saber si seremos capaces de restituir las imágenes faltantes y a partir de ellas, reponer las voces del pasado.
Arte y Simulacro: La Fotonovela como recurso para entender las dinámicas sociales contemporáneas en torno a la postfotografía.

Published: October 2019

Los conceptos de realidad y ficción en torno al tratamiento de la identidad, en la dicotomía de lo público y lo privado, ofrecen una línea de estudio para entender y reinterpretar cualquier imagen del archivo desde las artes, asumiendo y entendiendo la necesidad de un concepto reciente: la “postfotografía”. Pero este concepto, lejos de las disociaciones de las investigaciones en las artes visuales y las de la cultura visual, ofrece algunas cuestiones ambiguas cuando tratamos la imagen generada en las redes. Los medios de comunicación social, la proliferación y dominio de las redes sociales, y la universalización de los dispositivos móviles de alta capacidad en la gestión de comunicación, utilización y transformación de las imágenes, nos obligan a tomar en consideración el nuevo escenario y a plantear un debate sobre la realidad en la que vivimos, y la posible tergiversación de los modelos de vida, el autoconocimiento y el tratamiento de la identidad.Este estudio plantea y desarrolla una práctica educativa, basada en una experiencia de autoconocimiento a partir de las imágenes de archivo del entorno familiar. Estas imágenes, conocidas familiarmente pero ajenas a mi propia experiencia, ya que se trata de otras identidades cercanas en la línea del tiempo, son usadas para generar una nueva forma narrativa que las enlace, las cuestione y las redefinan en torno a mi propia identidad y biografía. La fotonovela me permite adoptar una posición crítica, creativa y constructiva para entender los nuevos modelos de representatividad social a través de las redes y de los media. Hoy nos remitimos constantemente a la necesidad de 'ser un otro mejorado', transmutado por las modas, y dominado por lo que se ha venido en denominar 'la cultura influencer’ para construir formas de representatividad que reformulan nuevas formas de ser en lo social. Si lo real puede ser considerado una ilusión y su recreación una constatación del individuo en el mundo, debemos de empezar a considerar este hecho y sus procesos, y plantear un tratamiento en los contextos educativos y estrategias críticas basadas en la imagen mediática que permitan su comprensión y desactivación.
