The Glory of Semarang Coastal City in the Past, Multi-Ethnic Merchants and Dutch Commerce
Authors: Rukayah R. Siti , Abdullah Muhammad
Published: April 2020

In The Image of the City, Lynch describes how individuals perceive and recall features in urban spaces. Lynch's approach is categorized by paths, nodes, edges, districts, and landmarks – giving shape to individuals' mental representation of the city. Recently, to test that theory on a large-scale city requires high accuracy to understand a city. So, it requires tools such as computational techniques using the GIS system. The cities of the 14th-18th centuries were not as complicated as the ones Lynch was dealing with in the 1960s. How do you reveal the image of the city? The image of the city in the past had not been explored yet. To explore the glory of Semarang city, Central Java, Indonesia, as Venetia van Java, which has the sugar industry in Asia, and the first railway track in Indonesia, you can still use hand-drawn sketches to reconstruct the image of the old city. Old data such as maps, photographs, and videos are integrated to reconstruct the image of the city in the past. Recently, the name of port of Semarang, Tanjung Emas– cape of gold – implies the glory of Semarang. The Semarang seaport played an important role in the pre-colonial and colonial eras. The architectural heritage at the two-river estuary of the Semarang coast uncovers the history of naming it the ‘cape of gold’. The river serves as roads and train lines, as the path is important as a tool to evaluate the city transportation facilities for urban planners, watershed services, and urban conservation.

Published: April 2020

It has been relied upon and is still found in the fields of scientific research, especially astronomy, medicine (for accurate disease diagnosis), biology, archeology, and industry on video and still images. The low accuracy and quality of some videos are often due to a poor lens type or angle, which may be due to a lack of photographic experience, or because of the older sections, which can be affected by the coolness of the surrounding perimeter. This research was completed using simple methods of processing based on using a program to convert video to individual images, then a number of image processing operations to improve quality, and finally re-assemble the images to the video more accurately than the original and in our own way. The proposed process consists of several steps: cutting the video clip into a set of images, performing various operations, such as using the contrast filter first, discovering the edges, smoothing the image, and improving image density prior to assembly. We finally assemble the images back into clips. This has been the process we used on many of the films affected by noise, or damaged for a long time, and has proven our ability to improve the quality of the video.

Medical implementation is a field for supporting the future of wireless networking. A patient who is remotely situated can be treated remotely by communicating their status to caregivers in real-time. The e-healthcare devices were created mainly to observe physiological parameters such as body temperature, level of oxygen saturation, heart rate, amount of blood sugar, blood pressure, etc. With the development of wireless technologies, however, there has been a variety of variations and improvements in e-healthcare systems. Tele-biomedical apps with wireless networks for mobile communications such as telemedicine is a distant medical practice that enables cooperation between distinct people and promotes their collaborative attempts to diagnose or treat illness through IT and telecommunications. Medical servers and databases are remote computers that assist medical personnel and hospitals analyze and monitor vital signs and provide patients with adequate facilities in real time. The tele-biomedical environment is a general word used for the use of mobile phones (handheld devices) and other wireless systems and communication devices to inform users or customers of medical preventive healthcare facilities. The scheme launched applications that can adapt to other illnesses, including elevated BP, diabetes and fever, through biometric devices such as thermometers, glucometers and densitometers to transmit patient data from an Android application based on the user's sensitivity to a social media scheme, such as a software application to monitor children's vaccination coverage.

Authors: Ahmed Zainab J. , George Loay E.
Published: April 2020

This investigation proposed an identification system of offline signature by utilizing rotation compensation depending on the features that were saved in the database. The proposed system contains five principle stages, they are: (1) data acquisition, (2) signature data file loading, (3) signature preprocessing, (4) feature extraction, and (5) feature matching. The feature extraction includes determination of the center point coordinates, and the angle for rotation compensation (θ), implementation of rotation compensation, determination of discriminating features and statistical condition. During this work seven essential collections of features are utilized to acquire the characteristics: (i) density (D), (ii) average (A), (iii) standard deviation (S) and integrated between them (iv) density and average (DA), (v) density and standard deviation (DS), (vi) average and standard deviation (AS), and finally (vii) density with average and standard deviation (DAS). The determined values of features are assembled in a feature vector used to distinguish signatures belonging to different persons. The utilized two Euclidean distance measures for matching stage are: (i) normalized mean absolute distance (nMAD) (ii) normalized mean squared distance (nMSD). The suggested system is tested by a public dataset collect from 612 images of handwritten signatures. The best recognition rate (i.e., 98.9%) is achieved in the proposed system using number of blocks (21×21) in density feature set. With the same number of blocks (i.e., 21×21) the maximum verification accuracy obtained is (100%).

Published: April 2020

The automatic detection of white blood cells remains an unresolved problem in medical imaging. white blood cell image analysis has included researchers from the fields of medicine and computer vision alike. In this paper, a new algorithm for white blood cell detection is proposed. This algorithm is based on the binary conversion of red and blue identity compounds and gradient after defining the values of specific areas while deleting unwanted small areas depending on the median filter. In the experimental results from white blood cell images, the proposed algorithm was compared with several other algorithms for detection. A quality scale was used that compares manual cell counts with the automatic detection of algorithms where the proposed algorithm obtained a high distinction accuracy reaching 98 percent, as compared to other methods.
Fiqh Pluralism: Comprehensive Analysis of Nurkholish Madjid Ideas Regarding Hermeneutics
Authors: Ridwan Ahmad Hasan
Published: April 2020

The idea of Cak Nur (Nurkholish Madjid)in the history of Islamic thought is a complex actual problem. His ideas can be portrayed in two ways, namely pure science and applied science. In the area of "pure science," inclusive hermeneutics is a unique basis for the idea of pluralism. Inclusive hermeneutics views pluralism as a product of a new intellectual tradition. The new intellectual tradition certainly brings a change agenda in the process of the historical continuity of thought in Indonesia. The purpose of this article is to analyze the inclusive hermeneutics of Cak Nur in the concept of fiqh pluralism. The conclusion of this article is that Cak Nur is able to conduct various discourses over the boundaries of normativity so that he can enter the universal realm. This can be seen in the discourse on religions and culture. Cak Nur can break through the barriers that exist in these two problems by trying to dialogue the meeting point of the equation. As a scholar, Cak Nur took this position so that he could sit together with other scientists from various cultures and different beliefs to dialogue and discuss a problem objectively. In the area of applied science, there is an internal influence regarding Islam. This area must be held by Cak Nur because if someone has offered a value, he will enter the element of subjectivity. In studying Islam, he became a Muslim scholar who enlightened byhis flexibility and scientific authority.

Authors: Al Wahab Adel A. Abed , Nasir Nihad Mahmoud , Khalil Adil I.
Published: April 2020

It is well known that dynamical systems deal with situations in which the system transforms over time. In fact, undertaking a manual simulation of such systems is a difficult task due to the complexity of the computations. Therefore, a computerized simulation is frequently required for accurate results and fast execution time. Nowadays, computer programs have become an important tool to confirm the theoretical results obtained from the study of models. This paper aims to employ new MATLAB codes to examine a discrete predator–prey model using a difference equations system. The paper discusses the existences and stabilities of each possible fixed point appearing in the current model. Furthermore, numerical simulations fixed by a certain parameter to plot the diagrams are presented. Our results confirm that the systems sensitive to initial conditions are chaotic. Furthermore, the theoretical results as well as numerical examples illustrated that the discrete model exhibits complex behavior compared to a continuous model. The conclusion drawn is that the numerical simulation is an important tool to confirm theoretical results.

Published: April 2020

Wallachian Culture Route is a cultural tourism route that presents the natural values of the Carpathian Mountains and the cultural heritage of Wallachian settlers. The main objective for the creation of thxe route is the development and promotion of sustainable tourism in the Carpathian Mountains. The route is also a way to enrich and diversify the range of touristic offers in Carpathian boroughs on the basis of their own, frequently unused human and landscape capital.

The idea of the route reflects the community of the Carpathian highlanders through nomenclature, the music that is manifested in the system of village establishment, spread of fields, glades along with huts, and through the contemporary realization of cooperative, communal activities that refers back to the organization of a Wallachian hut – mutual husbandry.

Affiliation with the “Wallachian Culture Route” teaches respect for work and the achievements of past generations, also drawing attention to the cultural heritage of the Carpathian Arc.
Protection of old forges in Sułkowice – symbol of the local crafts-manship
Authors: Zin Barbara
Published: April 2020

Wooden structures linked to agriculture are disappearing from the image of the Polish countryside, villages and small towns at the beginning of the 21st century. It is worthy to start the discussion on the fate of desolate, deteriorating forges, sawmills, carpentries, or water mills which are relics of the traditional technology. Sułkowice, a small town in the Małopolskie voivodeship, has been known for ages as a prominent centre of blacksmiths and their craft. Even today one feels the specific character of the landscape; in the mid-19th century circa 1000 blacksmiths worked there. Tradition lived until the times after the Second World War – when artisans in Sułkowice forged, among others, artful fittings for the MS ‘Batory’ [famed Polish liner]. Inventories, surveys and measurements of old forges, elaborated by the authoress within the framework of the research grant “Image of villages and small towns in Poland of the last decade of the 20th century” (led by Prof. Wiktor Zin) led to gathering of the documentation of circa 20 structures hailing from the close of the 19th century. After 20 years that elapsed since the research there are only a few left, and their days are numbered. Local Programme of Revitalisation of the Town from the year 2007 which is a strategic plan for enterprises aiming at amelioration of the area, does not mention the protection of the last witnesses of the local crafts’s tradition. Whereby the activisation of the local community, deriving from the tradition of the place, should be the aim of such a programme. Thus maybe there should be reconstruction and later ‘cyclical rebuilding’ of the structures which have no chance to exist with their primary function? “Old-new” wooden structures shall be a reminder of the blacksmiths’ tradition.

Impact of epoxy resin modification on their strength parameters
Authors: Szewczak Andrzej
Published: April 2020

Modifications of polymer composites are one of the fastest developing fields of technology. Research is focused on two directions: obtaining new composites or modifying existing materials. The first group of tests uses methods for preparing new chemical formulas of polymers containing, as the main structural element: carbon (organic polymers) or silicon (inorganic polymers). In the second group, the research consists in seeking methods to modify the properties of polymers. In building construction, among the others types, the glues (adhesive polymers) are used. They are exerted to connect materials with different physical andmechanical properties. Under the influence of the factor initiating the crosslinking reaction (hardener or temperature), the polymers obtain a solid form. The strength of the glued joint depends on the initial parameters of the glue resin and the target substrate of its application.The glued surface is usually the weakest element in this connection in terms of the possibility of damage due to the effects of loads, therefore methods to improve the strength parameters of adhesives are sought. The study presents the results of own research on methods of modification of a selected epoxy resin used in the technique as a glue. In order to ensure effective mixing of the adhesive with the fillers, ultrasound energy was used. After the resin had hardened, tests were carried out to determine the hardness and tensile strength of the obtained composites. Based on the results, SEM analysis and observation of the effect of ultrasound, the phenomena affecting the changes in the above mechanical properties were explained.
Analysis of Specific Absorption Rate on Six Layer Human Head Model
Authors: Swaminathan Anand , A Ramprakash , K Dhejonithan
Published: April 2020

Despite numerous advantages, mobile phones cause
serious health issues to people due to electromagnetic radiation. Various head
models already exist to study the impact of radiation on a human head. The accuracy
of the measurement of power absorbed by different layers of a head should be
high. A new head model with six layers is proposed in this paper. Parameters
such as dielectric constant, conductivity and mass density of different tissue
layers skin, fat, bone, Dura, cerebrospinal fluid (CSF), and brain are
extracted from the Federal Communications Commission (FCC) database. To study
the impact of radiation in the proposed model, standard planar inverted F-antennas
(PIFA) capable to radiate at 1.7 GHz and 2.4 GHz are used. Simulations are
performed using ANSYS Electromagnetics Suite. The analysis shows that the specific
absorption rate (SAR) in the brain layer decreased in the proposed model when
compared to the existing model.
A Formal Approach To Validate Block-Chains
Authors: Alroobaea Roobaea
Published: April 2020

Our goal is to propose a suitable approach for validating blockchains. For this purpose, we intend to adopt formal methods which are based on strong mathematical foundations. More precisely, we follow a model-based testing approach. The latter consists in describing the behavior of the system using a speciﬁc formalism, deriving test cases from the obtained model and then executing the obtained tests on the implementation to check whether it is correct or not. The adopted formalism corresponds to the timed automaton Model. The generated tests may be either digital or analog. Moreover, we propose several techniques which allow to solve the state explosion which may be encountered during the veriﬁcation and test generation phases.

El mosquito tigre es una especie invasora originaria del sudeste asiático que puede actuar como vector potencial de diversas arbovirosis como el dengue, el chikunguña y el zika. Desde el año 2004 en que se detectó por primera vez en España, se ha extendido por el litoral mediterráneo y otras áreas del interior peninsular, siguiendo una progresión que también se da en otras regiones de Europa y del mundo. En el mes de septiembre de 2018 se detectó su presencia en el municipio de Velilla de San Antonio (Comunidad de Madrid). Se estableció un grupo de trabajo entre salud pública, la Facultad de Ciencias Biológicas de la Universidad Complutense de Madrid y el ayuntamiento para definir y coordinar las actuaciones. Se establecieron dos áreas de trabajo, una de vigilancia, de 400-500 metros desde el punto en el que fue detectado y otra de actuación prioritaria, de 150-200 metros, con el objetivo de evaluar el área afectada, reducir su población e intentar su eliminación si ello fuera posible.
Semantic ambiguity does not imply syntactic ambiguity
Authors: López-Astorga Miguel
Published: April 2020

A problem to solve in generative grammar is to account for why children are able to note when a sentence or expression is ambiguous, even if they have not received explicit training for that. The theory of mental models can give an explanation in that way. That explanation is based upon the idea that people interpret linguistic messages by considering the semantics models corresponding to them, and it has been also proposed that the syntactic structures of those messages can be recovered by taken those very models into account. However, the point of this paper is that it tries to show that ambiguity at semantic level, that is, the cases in which models referring to different facts can be attributed to one sentence, does not necessarily lead to ambiguity at syntactic level. As it is argued, it is possible to capture models describing several opposite circumstances by means of only one logical form.

A crise da razão: elementos para pensar a educação moral no campo da Bioética
Authors: De Castro João Cardoso , De Castro Murilo Cardoso
Published: April 2020

É lugar comum a ideia de que vivemos uma crise moral, que nos assola de maneira radical nos dias de hoje. Neste sentido, um fluxo grande de trabalhos, no campo da saúde, procura delinear os contornos específicos desta crise, bom como esboçar algumas possibilidades de enfrentamento aos seus desdobramentos, com ênfase no que se consagrou na literatura como "educação moral". Na esteira destas questões, propomos este ensaio cujo objetivo é estabelecer uma perspectiva diferente para a crise. Através de um esforço de natureza filosófica, e tendo o filósofo Martin Heidegger como guia desta caminhada, procuramos discutir a referida crise, abordando sua natureza mais essencial e denunciando a insuficiência da "educação moral" contemporânea face à natureza da crise.
O Discurso de Aristófanes no Banquete de Platão
Authors: Menezes Luiz Maurício Bentim da Rocha
Published: April 2020

O Banquete é a obra de Platão que fala sobre o Amor (Éros) por excelência. Nosso trabalho irá se centrar no discurso proferido por Aristófanes que, no intuito de falar de todos os amores possíveis entre os humanos, irá fazer aquele que seria o primeiro mito sobre gênero, isto é, o mito do andrógino. Será através desse mito que será possível se estabelecer um sentido para a plenitude do amor entre os homens ou, como preferimos dizer, um todo erótico que se forma a partir da divisão da humanidade em três gêneros diferentes. Aristófanes, dessa forma, consegue demonstrar o significado do amor da maneira mais ampla possível. Por fim, iremos confrontar o discurso aristofânico com a defesa do amor dada por Sócrates e a relação que ele estabelece entre o todo erótico e o Bem.
Política e ciência em Hannah Arendt
Authors: Briskievicz Danilo Arnaldo
Published: April 2020

Diferenciamos e problematizamos dois tipos de discursos do mundo atual a partir do pensamento de Hannah Arendt, o científico e o político. Analisamos no interior de sua obra a partir da aplicação do método de pesquisa bibliográfica o conflito entre política e ciência. Como resultado da pesquisa apresentamos as relações entre política e ciência em Arendt em três eixos norteadores: o primeiro trata do páthos da eliminação do discurso e da ação pelas teorias científicas herdeiras da crise do mundo moderno em que politicamente, o problema da redução do valor da ação no espaço público para a solução dos conflitos humanos, em que há uma diminuição no reconhecimento da importância do discurso e da presença no mundo comum, afeta o destino das comunidades; o segundo eixo trata da indistinção moderna – teórica e prática – entre ação e processo, ou seja, entre política e ciência; o terceiro eixo trata de esclarecer o que, de fato, para Arendt, é a atividade da ação, que faz do homem um ser político. Dessa forma, apresentamos a solução da irreversibilidade e da imprevisibilidade da ação no ponto de vista arendtiano a fim de esclarecer que o discurso científico é processual e ligado à fabricação enquanto que a ação é o fundamento da teoria da ação arendtiana.
A Lucidez dos loucos: Nietzsche e outros
Authors: Martins Rogerio Parentoni
Published: April 2020

A aceitação das supostas causas da loucura variou na história das culturas. Porém, quaisquer sejam as culturas há dificuldades de se estabelecer claros limites a partir dos quais a loucura pode ser objetivamente identificada. Platão considerava a loucura promovida por meio de um espírito místico que a poucos inspirava. Os pensamentos medieval e renascentista admitiam a loucura como de fundo religioso, moral, médico, divino ou diabólico, boa ou má. No final do século XIX até meados do século XX, a etnopsiquiatria desconsiderava a importância da cultura e da personalidade para entender a loucura, cuja origem seria proveniente da manifestação de uma estrutura patológica básica e universal. De modo semelhante, Freud admitia que a loucura já estivesse presente no inconsciente. A partir dos séculos XVII e XVIII, o cogito cartesiano estabeleceu a supremacia da razão em obter-se conhecimento, o que no século XX motivou a controvérsia Foucault versus Derrida sobre a exclusão da loucura do cogito. No passado, talvez por faltar compreensão adequada, o alienado era excluído do convívio social e tratado por meio de práticas "curativas" muitas vezes violentas. Por isso, muitos tiveram sua doença agravada ou se tornaram abúlicos. Para realizar o diagnóstico da loucura, os profissionais capacitados não devem estabelecer barreiras teóricas entre si e o paciente; este deve ser amplamente ouvido e tratado por equipe interdisciplinar. Finalmente, para Nietzsche a loucura estaria associada ao ímpeto criativo.

O encarceramento feminino recente no Brasil
Authors: Ribeiro Gomes Simone
Published: April 2020

O trabalho visa contribuir para o entendimento do aumento dos índices de encarceramento feminino a partir de uma reflexão sobre o envolvimento das mulheres julgadas com base na Lei de Drogas (Lei nº 11.343/2006). A partir de um trabalho de campo em presídios femininos e masculinos, em três cidades: Rio de Janeiro, Manaus e Fortaleza, além de entrevistas semiestruturadas com atores do sistema penitenciário, o texto aborda o papel das mulheres apenadas, na reconfiguração, que deriva em uma manutenção e reorganização das facções criminosas, dentro e fora dos presídios. Realiza-se uma revisão de literatura na qual constam estudos de gênero articulados à discussão prisional, além de textos clássicos da sociologia da violência.

Uma ferramenta para aplicação de mapeamentos entre termos SNOMED CT, CID-10 e CIAP-2 e enriquecimento terminológico em Segundas-Opiniões Formativas sobre hipertensão e diabetes
Authors: Santana da Silva Filipe , Nícolas Bettoni Giovani , Gomes Tavares dos Santos Bruno
Published: April 2020

Introdução: Um Sistema de Registro Eletrônico em Saúde (S-RES) requer que sejam utilizadas terminologias e vocabulários controlados (como a SNOMED-CT, CID-10 e CIAP-2) para garantir a interoperabilidade semântica entre sistemas. Todavia, nem todos os S-RES incorporam esse tipo de abordagem, minimizando a utilização das fontes terminológicas para a codificação de documentos clínicos. Objetivo: O objetivo deste trabalho é apresentar uma ferramenta que permita explorar os mapeamentos existentes entre CID-10, CIAP-2 e SNOMED CT para indicação de termos correlacionados para enriquecimento terminológico em SOFS. Método: Nossa abordagem permite recuperar SOFs diretamente da BVS APS utilizando Web scraping e a construção de uma solução baseada em bancos de dados para sugerir mapeamentos provenientes de fontes consolidadas, facilitando a consulta e a recuperação de novos códigos da CID-10 e da SNOMED CT. Resultados: O resultado foi a disponibilização de uma estratégia simples para explorar mapeamentos entre os termos das três fontes terminológicas. Conclusão: Como conclusão, esta abordagem pode ser incorporada para a sugestão de novos termos na codificação de SOFS ou de S-RES num contexto mais amplo. Além disso, trabalhos futuros nestes mapeamentos são necessários para expansão para outros módulos importantes na atenção primária.

Quantification of the Effects of Coating Parameters on the Properties of TiAlZrN Coatings
Authors: Sert Yaşar
Published: April 2020

In this study, TiAlZrN layer was coated on AISI H13 substrate surface with variable substrate bias voltage, Zr target current, and ambient pressure deposition parameters by using closed field unbalanced magnetron sputtering (CFUBMS) technique. The main goal of this paper is to determine the effect percentages of these variable parameters on the properties of TiAlZrN coatings by Analysis of Variance (ANOVA). These coating properties include average grain size, thickness, hardness, adhesion strength and wear resistance. The numerical data obtained as a result of this study will shed light on the select of parameters which have a direct effect on coatings to the researchers who will work on this topic. The parameters used as variables in the deposition process were leveled with Taguchi experimental (33) design method. Average grain size and thickness of coatings were established by SEM images. The average grain sizes of coatings were between 290 and 440 nm and the most effective parameter was substrate bias voltage with 58.4 %. The hardness, adhesion strength and wear properties of the coatings were determined using micro hardness tester, scratch test and ball on disc wear device respectively. The maximum hardness of coatings was 1674 HV, while the wear resistance was increased by 37 times compared to the substrate material. The maximum adhesion strength value of the coatings was reached 56N. The superiority of the effect of substrate bias voltage on the hardness, adhesion strength and wear resistance of the coatings compared to other deposition parameters was again prominent (respectively 86.15%, 53.63% and 70.86%). Also, the hardness and wear resistance properties were found to be directly related to each other. The sample with the highest coating hardness also showed the highest wear resistance performance. In the sample with the lowest hardness, this situation found to be similar.
Acetonitrile Synthesis via Ammoxidation: Mo/zeolites Catalysts Screening

Published: April 2020

Mo/zeolites catalysts were investigated in ethane and ethylene ammoxidation into acetonitrile. The catalysts were prepared either in solid‒solid or liquid‒solid interface after varying different parameters. The stabilization of Mo species upon the exchange is dependent on the hydrophilic/hydrophobic character of the zeolite and the type of Mo precursor. In fact, zeolites with low Si/Al molar ratios should be avoided due to their higher dehydration enthalpy values (Δdehyd.H). On the other hand, the use of MoOCl4, Mo(CO)6 and MoCl3 precursors and zeolites with high Si/Al ratios led to inefficient [Mo7O24]6‒ species and amorphous MoO3 which catalyzes the combustion reaction. Nevertheless, the use of MoCl5, MoO3 and MoO2(C5H7O2)2 led to promising activities. In catalysis, [MoO4]2‒ species are required to activate C2H6 into C2H4, while [MoxO3x+1]2‒ (x =1, 2) species catalyze the ammoniation of C2H4 and the ethylamine dehydrogenation into CH3CN. Interestingly, active catalysts could be obtained by humid impregnation and a simultaneous oxidative treatment. Such a treatment improves the dispersion state of crystalline MoO3, which activate ethane molecules. It is judicious to perform C2H6 oxidative dehydrogenation before ammoxidation since the interference between the different investigated parameters could be noted.
