Binary Grasshopper Optimization Based Feature Selection for Intrusion Detection System Using Feed Forward Neural Network Classifier
Authors: Jeyakarthic M. , Thirumalairaj A.
Published: May 2020

Background:

Due to the advanced improvement in internet and network technologies,
significant number of intrusions and attacks takes place. An intrusion detection system (IDS)
is employed to prevent distinct attacks. Several machine learning approaches has been
presented for the classification of IDS. But, IDS suffer from the curse of dimensionality that
results to increased complexity and decreased resource exploitation. Consequently, it
becomes necessary that significant features of data must be investigated by the use of IDS for
reducing the dimensionality.

Aim:

In this article, a new feature selection (FS) based classification system is presented
which carries out the FS and classification processes.

Methods:

Here, the binary variants of the Grasshopper Optimization Algorithm called
BGOA is applied as a FS model. The significant features are integrated using an effective
model to extract the useful ones and discard the useless features. The chosen features are
given to the feed forward neural network (FFNN) model to train and test the KDD99 dataset.

Results:

The validation of the presented model takes place using a benchmark KDD Cup
1999 dataset. By the inclusion of FS process, the classifier results gets increased by attaining
FPR of 0.43, FNR of 0.45, sensitivity of 99.55, specificity of 99.57, accuracy of 99.56, Fscore of 99.59 and kappa value of 99.11.

Conclusion:

The experimental outcome ensured the superior performance of the presented
model compared to diverse models under several aspects and is found to be an appropriate
tool for detecting intrusions.

Authors: Campos Fernanda Safira Soares , Araújo Bruno
Published: May 2020

Esta pesquisa analisa editoriais dos jornais O Globo e O Estado de S. Paulo sobre a proposta de Reforma da Previdência Social apresentada ao Congresso Nacional pelo ex-presidente Michel Temer (PMDB) como parte de um pacote de reformas de índole liberal perpetrada por seu governo. Com base na Teoria do Enquadramento, que funciona como instrumental teórico-metodológico para este texto, buscamos compreender os enquadramentos construídos pelos dois jornais em seus editoriais, de forma a perceber como eles expressaram seus posicionamentos sobre o tema. Na análise, identificam-se os principais recursos retóricos utilizados pelos jornais a partir de categorias propostas por Robert Entman (1993). O estudo mostra a construção de enquadramentos midiáticos favoráveis à Reforma, com a defesa da sua inevitabilidade e a expressão de ideias diretamente alinhadas ao ideário neoliberal.

Authors: Leenen Jobbe P L , Leerentveld Crista , van Dijk Joris D , van Westreenen Henderik L , Schoonhoven Lisette , Patijn Gijsbert A
Published: May 2020

Background

Continuous monitoring of vital signs by using wearable wireless devices may allow for timely detection of clinical deterioration in patients in general wards in comparison to detection by standard intermittent vital signs measurements. A large number of studies on many different wearable devices have been reported in recent years, but a systematic review is not yet available to date.

Objective

The aim of this study was to provide a systematic review for health care professionals regarding the current evidence about the validation, feasibility, clinical outcomes, and costs of wearable wireless devices for continuous monitoring of vital signs.

Methods

A systematic and comprehensive search was performed using PubMed/MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials from January 2009 to September 2019 for studies that evaluated wearable wireless devices for continuous monitoring of vital signs in adults. Outcomes were structured by validation, feasibility, clinical outcomes, and costs. Risk of bias was determined by using the Mixed Methods Appraisal Tool, quality assessment of diagnostic accuracy studies 2nd edition, or quality of health economic studies tool.

Results

In this review, 27 studies evaluating 13 different wearable wireless devices were included. These studies predominantly evaluated the validation or the feasibility outcomes of these devices. Only a few studies reported the clinical outcomes with these devices and they did not report a significantly better clinical outcome than the standard tools used for measuring vital signs. Cost outcomes were not reported in any study. The quality of the included studies was predominantly rated as low or moderate.

Conclusions

Wearable wireless continuous monitoring devices are mostly still in the clinical validation and feasibility testing phases. To date, there are no high quality large well-controlled studies of wearable wireless devices available that show a significant clinical benefit or cost-effectiveness. Such studies are needed to help health care professionals and administrators in their decision making regarding implementation of these devices on a large scale in clinical practice or in-home monitoring.

Authors: Guest Jodie L , Sullivan Patrick S , Valentine-Graves Mariah , Valencia Rachel , Adam Elizabeth , Luisi Nicole , Nakano Mariko , Guarner Jeannette , del Rio Carlos , Sailey Charles , Goedecke Zoe , Siegler Aaron J , Sanchez Travis H
Published: May 2020

Background

The severe acute respiratory coronavirus 2 (SARS-CoV-2) pandemic calls for expanded opportunities for testing, including novel testing strategies such as home-collected specimens.

Objective

We aimed to understand whether oropharyngeal swab (OPS), saliva, and dried blood spot (DBS) specimens collected by participants at home and mailed to a laboratory were sufficient for use in diagnostic and serology tests of SARS-CoV-2.

Methods

Eligible participants consented online and were mailed a participant-collection kit to support collection of three specimens for SARS-CoV-2 testing: saliva, OPS, and DBS. Participants performed the specimen collection procedures during a telehealth video appointment while clinical observers watched and documented the suitability of the collection. The biological sufficiency of the specimens for detection of SARS-CoV-2 by reverse transcriptase–polymerase chain reaction and serology testing was assessed by laboratorians using visual inspection and quantification of the nucleic acid contents of the samples by ribonuclease P (RNase P) measurements.

Results

Of the enrolled participants,153/159 (96.2%) returned their kits, which were included in this analysis. All these participants attended their video appointments. Clinical observers assessed that of the samples collected, 147/153 (96.1%) of the saliva samples, 146/151 (96.7%) of the oropharyngeal samples, and 135/145 (93.1%) of the DBS samples were of sufficient quality for submission for laboratory testing; 100% of the OPS samples and 98% of the saliva samples had cycle threshold values for RNase P <30, indicating that the samples contained sufficient nucleic acid for RNA-PCR testing for SARS-CoV-2.

Conclusions

These pilot data indicate that most participant-collected OPS, saliva, and DBS specimens are suitable and sufficient for testing for SARS-CoV-2 RNA and serology. Clinical observers rated the collection of specimens as suitable for testing, and visual and quantitative laboratory assessment indicated that the specimens were biologically sufficient. These data support the utility of participant-collected and mailed-in specimens for SARS-CoV-2 testing.

Addressing Doctoral Student “Failure”: Catching Lost Souls
Authors: W. Kramer Michael
Published: May 2020

Statistics indicate that 45-50% of doctoral students who finish their course work never finish their degrees (https://www.statisticssolutions.com/almost-50-of-all-doctoral-students-dont-graduate/). This essay examines this problem as an example of fundamental attribution error and suggests that in some cases, but not all, success rates can be improved by making changes in the situation instead of blaming the students. It illustrates this point with examples of successful efforts to prevent students from failing to finish their degrees by advisors serving as process experts instead of content experts. It also points out that while being a process expert may increase the percentage of students who complete their degrees, it does not always lead to success. Rethinking this issue may assist educators as they attempt to help college students at all levels finish their degrees.
Ruralized or Not? Lived Experiences of Remote Distance Learning Students of the Institute for Distances and E-Learning (IDeL), University of Education, Winneba, Ghana
Authors: Owusu-Mensah Francis
Published: May 2020

The purpose of this study was to explore the variation in experiences of remote rural students who study with the Institute for Distance and e-Learning (IDeL) of the University of Education, Winneba (UEW) in Ghana. The study adopted the qualitative research strategy. Semi-structured interviews were used to collect data for the study. Purposively, three remote centres were selected. Ten (10) students were selected across the selected centres for the study. Data obtained from the study centers were analyzed thematically. The study found that lived experiences of the learners on remoteness depended not only on their geographical locations but were also relative to individual circumstances. With respect to students’ sense of connection with university staff and peers, most mentioned their contact with their personal tutor. Networks with peers were less common, a matter of concern if peer networks are integral to fostering improved retention and progression. It was recommended among others that IDeL should promote the use of various cell phone Smart Identity Modules Cards (SIM Cards) by students in remote areas, to enable them gain access to any of the cell phone network coverage in their rural setting.

Live Forensics Method for Acquisition on the Solid State Drive (SSD) NVMe TRIM Function
Authors: Pranoto Wisnu , RIadi Imam , Prayudi Yudi
Published: May 2020

SSD currently has a new storage media technology namely Solid State Drive Non-volatile Memory Express (SSD NVMe). In addition, SSD has a feature called TRIM. The TRIM feature allows the operating system to tell SSDs which blocks are not used. TRIM removes blocks that have been marked for removal by the operating system. However, the TRIM function has a negative effect for the digital forensics specifically related to data recovery. This study aimed to compare the TRIM disable and enable functions to determine the ability of forensics tools and recovery tools to restore digital evidence on the NVMe SSD TRIM function. The operating system used in this study was Windows 10 professional with NTFS file system. Typically, acquisition is conducted by using traditional or static techniques. Therefore, there was a need of a technique to acquire SSD by using the live forensics method without shutting down the running operating system. The live forensics method was applied to acquire SSD NVMe directly to the TRIM disable and enable functions. The tools used for live acquisition and recovery were FTK Imager Portable. The inspection and analysis phases used Sleutkit Autopsy and Belkasoft Evidence Center. This research found that in the recovery process of TRIM disabled and enabled, TRIM disabled could find evidence while maintaining the integrity of evidence. It was indicated by the same hash value of the original file and the recovery file. Conversely, when TRIM is enabled, the files were damaged and could not be recovered. The files were also not identical to the original so the integrity of evidence was not guaranteed.
Design, Synthesis and Antibacterial Evaluation of Hybrid Curcumin Based Pyrazole Derivatives
Authors: Anand Mohan Jha  , Md. Mansoor Alam
Published: May 2020

Present  work demonstrates  synthesis  and antibacterial  property  of new  pyrazole  derivatives.  A series  of new Curcumin based dihydropyrazoles has been synthesized with an objective to evaluate their antibacterial property. Dihydropyrazoles analogues were synthesized using Curcumin based chalcones and differently substituted phenylhydrazine derivatives. We used the previously designed Curcumin based chalconesto react with phenylhydrazine derivatives in ethanol in a catalyst free medium to afford new dihydropyrazole derivatives. Effect of substituent on reactivity was also studied. All the synthesized  pyrazole analogues were characterized  using proton and carbon NMR, Mass spectroscopy  and IR techniques. Effect of substituent on reactivity was explained on the basis of electronic effect generated due to groups on phenyl ring. Presence of dd (double doublet) in proton NMR spectrum of Dihydropyrazoles was also explained due to presence of optically active carbon of pyrazole ring. The synthesized library was screened for their inhibitory activity against 4 different bacterial strains 1. E. Coli (ATCC 9637), 2. Pseudomonas aeruginosa (ATCC BAA-427), 3. Staphylococcus aureus (ATCC 25923) and 4. Klebsiella pneumonia (ATCC 27736). Out of all the compounds evaluated, the compounds that exhibited IC50  value greater than 50µM,  were  considered  to  be  inactive.  We  established  an  important  SAR  based  on  the  structure  dependent  inhibitory potential of screened dihydropyrazoles.  Two compounds 4e and 4t having nitro and benzyl substitution respectively were showing the best inhibitory potential against Gram Positive bacterial strain Staphylococcus aureus with MIC value of 1.56 µg/ml. Compounds having Chloro and Methoxy substitution were found to be less effective against screened bacterial strains. Compounds 4a and 4b were selective towards Staphylococcus aureus species with the MIC value of 1.56 µg/ml for each. These pyrazole analogues were not showing inhibitory potential against other screened bacterial strains.

Espetáculo à mesa: midiatização da cozinha nos reality shows de gastronomia
Authors: Chaves Viviany Moura , Dantas Alexsandro Galeno Araújo
Published: May 2020

Os reality shows tem conferido uma visibilidade midiática ao tema da gastronomia, configurando-se numa estratégia convidativa para unir dois fortes elementos: o comer e o jogar. O estudo analisou sobre como a cozinha, em um cenário midiático, se tornou um espetáculo televisivo contemporâneo. Desta problematização, observou-se que o reality show gastronômico é a construção de um ideal de cozinha mediada por imagens e, portanto, feita para os olhos, numa frágil concepção mítica que investe no comer pela via imagética. Assim, a cozinha midiática pode ser compreendida como a concretização do espetáculo, sob a perspectiva de Guy Debord, apresentada de forma maquiada e distante da realidade que não pode ser alcançada, exceto por uma experiência vicária.

Caracterización de la tipología de fallos presentados en los pavimentos de la ciudad de Ocaña Norte de Santander
Authors: Gallardo-Amaya Romel Jesús , Quintero-Lemus Leidy Johana , Cuanalo-Campos Oscar Andrés
Published: May 2020

Los fallos en los pavimentos se presentan por el deterioro progresivo que les ocurre con el tiempo. Una forma de identificar los fallos es mediante una inspección visual, es así como en esta investigación se inspeccionaron varios tramos de las principales vías urbanas del municipio de Ocaña, Norte de Santander. La información se consolidó mediante formatos en donde se registraron coordenadas, anchos del carril, nivel de severidad, observaciones y registro fotográfico de los fallos. Una vez tabulada la información se encontró que fueron analizados 9.277 ml de tramos viales, de los cuales 3.051 ml (32.89%) tienen pavimento flexible y 6.226 ml (67.11%) pavimento rígido. En los flexibles las tipologías de fallos más representativas fueron piel de cocodrilo y baches y, para el caso de los rígidos fueron las grietas y desintegración. El grado de severidad de los fallos mencionados, tanto para el caso de los pavimentos flexibles como rígidos es de medio a alto; siendo esto un indicador de los niveles de deterioro que poseen los pavimentos en los sectores viales analizados. Muchos de los fallos pueden estar asociados a deficiencias en la estructura de los pavimentos y condiciones inadecuadas de los suelos de subrasante.
Calificación del indicador de espacio público efectivo y percepción de la comunidad en relación con la dinámica social del casco urbano del municipio de Ocaña (Norte de Santander)
Authors: Álvarez-Blanco Marlon Alfonso , Caicedo-Mantilla Maritza , Angarita-Castilla Wilson
Published: May 2020

En los últimos años la calidad de vida urbana de los habitantes del municipio de Ocaña se ha visto afectada, debido al crecimiento acelerado de la población y cambios en la dinámica social, desencadenada por factores detonantes como el desplazamiento forzado, incremento del índice de desempleo, influencia de la diversidad intercultural y aumento de la economía informal. En consecuencia, el municipio presenta un desorden urbanístico, haciendo que el tema del espacio público tome relevancia en la actualidad.  En este sentido se encontró que el índice de espacio público efectivo para el municipio es de   0,75 m2, lo que representa un déficit muy alto en cuanto a espacios de plazas, parques y plazoletas presentes en cada una de las comunas del  casco urbano. Sin embargo, se cuenta con un área verde en el municipio bastante importante, pero, que en su mayoría son suelos privados que limitan el acceso de las personas al goce y disfrute de estos espacios.  Es claro, que la  comunidad tiene una percepción negativa en cuanto al manejo y disposición de los espacios públicos, y se hace fácilmente identificable, que el área urbana del municipio ha crecido, pero no así el número de espacios públicos.

Published: May 2020

La siguiente investigación presenta la evaluación de los índices de contaminación para los ríos Tejo y Chiquito dentro del casco urbano de Ocaña; se escogieron seis puntos de muestreo estratégicos en temporadas de lluvia y estiaje, abarcando casi en su totalidad las dos fuentes hídricas. Se analizaron parámetros fisicoquímicos y microbiológicos para la utilización de los índices de contaminación, observándose que el índice de mayor incidencia es el de materia orgánica, dando como resultado un grado de contaminación muy alta en todo el tramo de estudio (exceptuando el punto de la Pradera, el cual es el punto de nacimiento del río Chiquito), también se identifican altas medidas de conductividad que muestran que los cuerpos de aguas se vean afectados por vertimientos de iones, aumentando el índice de contaminación por mineralización. La contaminación por sólidos suspendidos es variada en los seis puntos de muestreo, observándose un comportamiento natural de los cuerpos de agua durante su recorrido por el casco urbano. A manera de conclusión se sugiere la formulación y la aplicación de un plan de ordenamiento ambiental, acciones en saneamiento y manejo de vertimientos que sean participativos e incluyentes cuya base de formulación tenga atributos ecológicos y conciencia de los bienes y servicios que estos ofrecen.

New relations of the European Union and China: Friends or frenemies?
Authors: Arezina Sanja
Published: May 2020

After the promotion of ?Made in China 2025? initiative and the beginning of
US President Donald Trump?s tenure in power, in US and whole world there has
been a rising negative attitude towards Chinese presence. The launch of a
US-China ?trade war? and the closure of the US market for Chinese direct
investment and product coincided with growing discontent of EU member states
over the treatment that European companies have had at the Chinese market.
As a result, there has been a change of the positive perception of the PR
China by the EU member states, that was created mainly by strong inflow of
Chinese investments and assistance within the ?One Belt, One Road?
initiative, into a negative perception that is now forming policy changes
and introduction of protectionist measures towards Chinese direct
investments in European market. In this article, the author talks about the
different perceptions (positive and negative) that have been formed in the
PR China within the EU, the factors that have influenced the change in the
perception of EU member countries towards the PR China and the consequences
on the dynamics of the development of different policies at EU level. To be
able to prove the basic hypothesis that Brussels, unlike the US, still shows
some pragmatism by making policy changes moderate enough that the EU can
remain loyal to open market principles while preventing these principles
from becoming strategic vulnerability, the author uses the
structural-functionalist analysis, induction, and deduction.
Depth distribution of organic matter concentration and stocks in soils of Vojvodina
Authors: Ciric Vladimir , Manojlovic Maja , Nesic Ljiljana , Belic Milivoj
Published: May 2020

Despite the fact that soil organic matter (SOM) concentration is much lower
compared to mineral portion, its importance is very valuable for soil
fertility, agriculture, ecosystems and global environmental change. Soil
organic carbon (SOC) is a key component of SOM. The amount of SOC varies
greatly in surface layer of soil, but the vertical distribu?tion of SOC is
also very important. The purpose of the study was to investigate vertical
distribution of SOC in soil profiles of the most common soil types in
Vojvodina (Arenosols, Chernozems, Fluvisols, Vertisols, Solonetz) and in
different land uses (arable land, meadow and forest). Soil samples were
collected from 0-30, 30-60 and 60-100 cm depth. Dichromate wet oxidation
method proposed by Tyurin?s was performed to determine SOC concentration.
Except arenosols, obtained results showed the decrease of SOC concentration
with depth in all observed soil types and land uses. Vertisols had the
highest SOC concentration in both surface (0-30 cm) and subsurface (30-60
cm) layers compared to the other soil types, while arenosols had the highest
SOC concentration in the deepest layer (60-100 cm). Higher con?centrations
of SOC in surface layers were measured in forests and meadows in relation to
arable land, while in the lower layers these differences were not detected.
Differences in SOC concentration in observed soil types and land uses were
more pronounced in surface than in deeper layers. Soil organic carbon
concentrations in deeper layers were substantially different only between
soil types.
Wholegrain processing and glycaemic control in type 2 diabetes: a randomised crossover trial
Authors: Åberg Sebastian , Mann Jim , Neumann Silke , Ross Alastair B , Reynolds Andrew N
Published: May 2020

Objective: To consider the effects of wholegrain processing, specifically milling,
on glycaemic control in free-living adults with type 2 diabetes.

Research Design and Methods: Participants of this crossover trial were randomised
to two interventions of two-weeks, separated by washout. They
were advised to replace the grain foods they normally consumed with
intervention foods. Intervention foods were
nutrient matched wholegrain products of wheat, oats, and brown rice that
differed in their degree of processing. No other lifestyle
advice was given. Continuous glucose monitoring systems
were worn. Other cardiometabolic risk factors and alkylresorcinols (a biomarker
of wholegrain intake) were measured pre and post interventions.

Results: 31 adults
with type 2 diabetes (63±13 years old, BMI 32.4±7, HbA1c 7.5±3.4% (59±14mmol/mol))
commenced the trial, 28 (90%) completed both interventions. The increase in alkylresorcinols did not differ
between interventions and there was no difference in reported energy intake. Postprandial responses were 9% (95%CI 3-15%) lower following
breakfast and 6% (95%CI 1-10%) lower following all meals of less processed
whole grains when compared with finely milled grains. Day-long glycaemic
variability also reduced when measured by 24-hour standard deviation (-0.16mmol/l
95%CI -0.25 to -0.06) and MAGE (-0.36 95%CI -0.65 to -0.08). Mean change in body
weight differed by 0.81kg (95%CI 0.62 to 1.05) between interventions, increasing
during the finely milled intervention and decreasing during the less processed
wholegrain intervention. This was not a mediating factor for the glycaemic
variables considered.

Conclusions: Consuming less
processed wholegrain foods over two weeks improved measures of glycaemia in
free-living adults with type 2 diabetes when compared with an equivalent amount
of wholegrain foods that were finely milled. Dietary advice should promote the
consumption of minimally processed whole grains.

Published: May 2020

Global warming is an important issue to discuss because it is very impactful to human life, one of the factors influencing increase global warming is decreasing the green vegetation continuously that exist in both urban and rural areas. Especially in urban areas because it is the center of human activity. The high level of human activity centered in the city leads to an increase in the need for land use which will lead to reduced vegetation density levels. Utilization of remote sensing images can be used to determine the density of vegetation in an area. Vegetation density analysis can be done by means of digital imagery intrepetation using the transformation of NDVI (Normalized Different Vegetation Index). The purpose of this research is to know the land use through the calculation of vegetation index of residential area in Tasikmalaya city.

Narasi Islamisme dan Pesantren: Pola Penolakan Islam Politik di Pondok Pesantren Gontor Ponorogo
Authors: Aji Herlambang Andi Prasetyo
Published: May 2020

The polemic between religion and the nation-state is very recurrent and has the potential to strengthen when there are some critical changes in the political landscape. This case is reinforced by the results of a survey with the theme of scholars and nation-states, which reached 71.56 percent of scholars who received and 16.44 percent of scholars who rejected nation-states with different backgrounds. The purpose of this study is to explain the narrative of Islamism and its patterns of rejection in Pondok Modern Darussalam Gontor. The research method used is ethnographic in the sense of understanding the practice and life of individuals as part of a wider community and scope, with research subjects being religious scholars who are people with a formal religious education background in Pondok Modern Darussalam Gontor. The results showed that in facing the narrative of Islamism, the people of Pondok Modern Darusalam Gontor used a puritanical (puritanical moderate Islam) discourse of Islam with the perspective of political Islamization. Political Islamization does not mean that it wants to break down the ideology of the Unitary Republic of Indonesia, but rather still accepts the concept of the NKRI nation-state, including the ideology of Pancasila, only to clarify the basis and objectives following Islam by being semi-rejectionist towards a controversial interpretation of government.

 

Polemik yang terjadi antara agama dan negara-bangsa sangat recurrent dan berpotensi menguat ketika terjadi beberapa perubahan penting dalam lanskap politik. Hal ini diperkuat dengan hasil survei dengan tema ulama dan negara bangsa yang mencapai angka 71,56 persen ulama yang menerima dan 16,44 persen ulama yang menolak negara-bangsa dengan latar belakang berbeda. Tujuan penelitian ini adalah untuk menjelaskan narasi Islamisme dan pola penolakannya di Pondok Modern Darussalam Gontor. Metode penelitian yang digunakan adalah etnografis dalam pengertian untuk memahami praktik serta kehidupan individu sebagai bagian dari komunitas serta cangkupan yang lebih luas, dengan subjek penelitian adalah religious scholar yang merupakan orang-orang yang berlatar belakang pendidikan agama secara formal di Pondok Modern Darussalam Gontor. Hasil penelitian menunjukan bahwa dalam menghadapi narasi Islamisme masyarakat Pondok Modern Darusalam Gontor menggunakan wacana Islam moderat puritan (puritanical moderat Islam) aksepsionis dengan kacamata Islamisasi politik. Islamisasi politik bukan berarti ingin merobohkan ideologi NKRI, tetapi tetap menerima konsep negara-bangsa NKRI, termasuk ideologi Pancasila, hanya saja lebih memperjelas dasar dan tujuan-tujuan yang sesuai dengan Islam dengan bersikap semi-rejeksionis terhadap interpretasi pemerintah yang kontroversial.

The satellite requires the support of a robust sub system. On Board Data Handling (OBDH) is the core function of the satellite subsystem and has to be error free in managing the operation of the satellite. It should withstand the harsh environmental conditions in space that has a lot of hazards caused by radiations. In view of these two conditions, the OBDH design should be able to manage the operation and overcome the hazards of radiation. In order to manage the operation Real Time Operating System (RTOS) was applied. RTOS was able to manage the task efficiently and effectively. In the aerospace domain, RTOS has become popular because of its strength in managing the operating system. Error Detection and Correction System (EDAC) system was applied to make OBDH more robust. This paper discusses the implementation of the EDAC system in tandem with the RTOS behaviour to manage the operation and increase the robustness of the system. The findings show that OBDH can be programmed successfully using RTOS to handle critical and robust operations.
Applying the Method of Lagrange Multipliers to Derive an Estimator for Unsampled Soil Properties

Published: May 2020

Soil properties are very crucial for civil engineers to differentiate one type of soil from another and to predict its mechanical behavior. However, it is not practical to measure soil properties at all the locations at a site. In this paper, an estimator is derived to estimate the unknown values for soil properties from locations where soil samples were not collected. The estimator is obtained by combining the concept of the ‘Inverse Distance Method’ into the technique of ‘Kriging’. The method of Lagrange Multipliers is applied in this paper. It is shown that the estimator derived in this paper is an unbiased estimator. The partiality of the estimator with respect to the true value is zero. Hence, the estimated value will be equal to the true value of the soil property. It is also shown that the variance between the estimator and the soil property is minimised. Hence, the distribution of this unbiased estimator with minimum variance spreads the least from the true value. With this characteristic of minimum variance unbiased estimator, a high accuracy estimation of soil property could be obtained.

In this study, Li1+xAlxTi2-x(PO4)3 (0.0 < x < 0.5) was prepared by acetic acid­assisted sol-gel method. The structural properties of NASICON phosphates material with chemical formula LiTi2 (PO4)3 were observed using the Fourier transform infrared spectroscopy. NASICON is a family of crystalline phosphate with a general network system consisting of PO4 tetrahedra, thus bands were assigned by vibrations contributed by basic phosphates, in the wavenumber region between 1300 cm-1 and 600 cm-1. Experimental spectra indicated that all Li1+xAlxTi2-x(PO4)3 (0.0 < x < 0.5), heat treated at 600°C and 700°C for 3 hours in air, samples showed the presence of phosphate peaks with shift in frequency as Al3+ is substituted into the structure, and with increasing temperatures. Some bands broadened and overlapped causing it hard to analyze the arising bands. It however determined the existence of NASICON structure in all of the samples under study.

Materials that can enhance the sensitivity and selectivity of a biosensor are greatly in demand The nanocomposition of thionine (Th) and graphene can increase the electroconductivity of the working electrode used. Graphene is a very good electrical conductor but is also hydrophobic in nature. Composition with thionine gives it the capability to disperse well in water. Plus, thionine provides the opportunity for DNA probes to be immobilized due to the presence of the amino group in its structure. In this research, the thionine-graphene (Th-G) nanocomposite was synthesized through.filtration and characterised using scanning electron microscopy (SEM) to distinguish different elements coexist in the nanocomposite and to investigate the microstructure changes of the nanocomposite to confirm the composition. Different elements were analyzed to test the presence of both thionine and graphene in the composition. Physical characterisation through SEM proved the nanocomposition was a success.

This paper presents on ionic conductivity of MG30-PEMA blend solid polymer electrolytes (SPEs) prepared by solution cast technique. The analysis has shown that conductivity increases with the increasing salt composition. It is observed via x-ray diffraction analysis that the crystallinity of the sample decreased with the amount of salt composition as expected It is also observed that the dielectric value increases with increasing amount of LiCF3SO3 in the sample. Surface morphology revealed that ion aggregation occurred after optimum conductivity which has lowered the conductivity.

Published: May 2020

A good quality of rainfall data is highly necessary in hydrological and meteorological analyses. Lack of quality in rainfall data will influence the process of analyses and subsequently, produce misleading results. Thus, this study is aimed to propose modified missing rainfall data treatment methods that produced more accurate estimation results. In this study, the old normal ratio method and the modified normal ratio based on trimmed mean are combined with geographical coordinate method. The performances of these modified methods were tested on various levels of the missing data of 36 years complete daily rainfall records from eighteen meteorology stations in Peninsular Malaysia. The results indicated that both modified methods improved the estimation of missing rainfall values at the target station based on the least error measurements. Modified normal ratio based on trimmed mean with geographical coordinate method is found to be the most appropriate method for station Batu Kurau and Sg. Bernam while modified old normal ratio with geographical coordinate is the most accurate in estimating the missing data at station Genting Klang.
