Concrete paving blocks were first introduced in Holland to replace paver bricks which had become scarce due to the post-war building construction boom. In Kenya, paving blocks are used in construction of pavements in both residential and commercial areas. They can be used in areas with light or heavy traffic. Solid waste management has been a big challenge in Kenya for years. With growing population and demand for housing, it is of paramount importance to develop alternative uses of plastic waste. Concrete paving blocks containing PET flakes at 5%, 10%, 15%,25%,50%, 75% and 100% replacement ratios for coarse aggregates were prepared against a 30MPa control sample. Compressive strength, tensile strength and water absorption tests were carried out. at 5% replacement ratio, the paving blocks had compressive strength of 44.18MPa which is suitable for medium traffic areas

Voting is important for any democratic country. It can be considered as one of the major factors that make a government for the people and by the people. The most common methods of voting that currently exist are ballot-based voting, purely electronic methods, and Electronic Voting Machines, among others. Over the years, it has been a challenge to build a secure E-voting program that provides the privacy of current voting systems while offering a means of accountability and versatility. Using blockchain technology and cryptography we can make the process of elections as open and cost-effective as possible. In this review paper we discuss a new, blockchain-based electronic voting system that addresses some of the limitations in existing systems and evaluates some of the popular systems designed to create a blockchain-based e-voting system.

Entity Resolution (ER) is the process of identifying records that refer to the same real-world entity. It plays a key role in many applications as data warehouse, data integration, and business intelligence. Comparing every record with all corresponding records is infeasible especially for a big dataset. To overcome such a problem, blocking techniques have been implemented. In this paper, we propose a novel Efficient Multi-Phase Blocking Strategy (EMPBS) for resolving duplicates in big data. As per our knowledge, some state of art blocking techniques may result in overlapping blocks (i.e. Q-grams) which cause redundant comparisons and hence increase the time complexity. Our proposed blocking strategy has disjoint blocks and less time complexity compared to Q-grams and slandered blocking techniques. In addition, EMPBS is general and requires no restrictions on the type of blocking keys. EMPBS consists of three phases. The first one generates three single efficient blocking keys. The second phase takes the output of the first phase as an input to construct a compound key. The compound key is composed of concatenation of two single blocking keys. Three compound blocking keys are the output of this phase that will be used as an input for the last phase, which is generating the Efficient Multi-Phase Blocking Key (EMPBK). EMPBK is constructed using the union of two compound blocking keys. The implementation of EMPBS presents promising results in terms of Reduction Ratio (RR) as it achieves a higher value of RR than adopting only a single blocking key, while at the same time maintains nearly the same precision and recall. EMPBS reduced about 84% of the average number of comparisons accomplished in a single blocking key. To evaluate EMPBS, we developed a Duplicate Generation tool (DupGen) that accepts a clean semi-structured file as an input and generates labeled duplicate records according to certain criteria.

Flood is one of the most devastating natural calamities affecting parts of the state from past few years. The recurring calamity necessitates an efficient early warning system since anticipation and preparedness play a key role in mitigating the impact. Though heavy and erratic rainfall has been marked as one of the main reasons for flood in several places, flood witnessed by various regions of Kerala was the result of sudden opening of reservoirs indicating poor dam management. The unforeseen flow of water often provided less time for evacuation. Prediction thus plays key role in avoiding loss of life and property, followed by such calamities. The vast benefits and potentials offered by Machine Learning makes it the most promising approach. The developed system is a model by taking Malampuzha Dam as reference. Support Vector Machine (SVM) is used as machine learning method for prediction and is programmed in python. The idea has been to create early flood prediction and warning system by monitoring different weather parameters and dam-related data. The feature vectors include current live storage, current reservoir level, rainfall and relative humidity from the period 2016-2019. Based on the analysis of these parameters, the open/closure of shutters of the dam is predicted. Release of shutters has varied impacts in the nearby regions and is measured by succeeding prediction, by mapping regions on grounds of level warning to be issued. Warning is issued through Flask-based server, by identifying vulnerable areas based on flood hazard reference for regions. The dam status prediction model delivered highest prediction accuracy of 99.14% and associated levels of warning has been generated in the development server, thus preventing unexpected release.

Online financial frauds are one of the leading issues in the fields of digital forensics and cyber-security today. Various online firms have been employing several methodologies for the prevention of finance-related malpractices. This domain of criminal activity is becoming increasingly common in the present cyberspace. In this paper, we will try to implement an online financial fraud investigation using the digital forensics tool: Autopsy. A few existing cyber-security techniques for the investigation of such crimes, namely the Formal Concept Analysis and Confirmatory Factor Analysis; have been analyzed and reviewed. These techniques are primarily based on mathematical cyber-security concepts. Henceforth, it has been tried to find out whether the investigation of similar crimes can be done satisfactorily using the readily-accessible digital forensics tool: Autopsy. Also, it has been explored whether the aforementioned cyber-security techniques can be embedded along with the digital forensics tool to achieve the best results, through training a bot to automatically perform accurate investigations of such crimes. Thus, it has been tried to automate the process of online financial fraud investigation.

Cyberbullying constitutes a threat to adolescents’ psychosocial wellbeing that developed alongside technological progress. Detecting online bullying cases is still an issue because most of victims and bystanders do not timely report cyberbullying episodes to adults. Therefore, automatized technologies may play a critical role in detecting cyberbullying through the use of Machine Learning (ML). ML covers a broad range of techniques that enables systems to quickly access and learn from data, and to make decisions about complex problems. This contribution aims at deepening the role of ML in cyberbullying detection and prevention. Specifically, the following issues are addressed: i. identifying the features most frequently considered to develop ML models predicting cyberbullying; ii. identifying the most used ML algorithms and their evaluation methods; iii. understanding the implication of ML for prevention; iv. highlighting the main theoretical and methodological issues of ML algorithms in predicting cyberbullying. To answer these research questions, a systematic review of literature reviews, from a total of n=186 records from online databanks, has been conducted. Ten literature reviews have been elected to analyze and discuss evidence about ML preventative potential against cyberbullying. Most of the models used content-based features to predict cyberbullying. The majority of these features includes words written in social network posts, whereas Support Vector Machine, Naïve Bayes, and Convolutional Neural Networks are the most used alghorithms. Methodological and technical issues have been critically discussed. ML represents an innovative preventative strategy that may optimize and integrate educational programs for adolescents and be the starting point of the development of technology-based automatized detection strategies. Future research is challenged to develop algorithms capable of detecting cyberbullying from several multimedia sources.

How to reduce reckless driving in resource-constrained situations?
Authors: Singh Bhanu Pratap , Singh Nirvisha
Published: July 2020

Most of the data gathering devices used for monitoring driver’s behavior
require large storage, strong cellular signals, and unlimited internet.
Touching mobile devices, during driving, is prohibited by many law enforcement
agencies. There are situations, especially in developing countries, where people
get stuck on roads with a low battery, low device-memory, and no mobile
network. The drivers in such situations are not able to
report against reckless drivers effectively. This paper proposes the
framework of the “citizen reporting program” (CRP) aided with mobile apps to
reduce reckless driving in such resource-constrained
situations (RCS). A mobile app was designed, developed, and tested as a
tool for this purpose. It could convert speech to text without a cellular
network, capture the nearest geolocation, and send data to a server on the network
or internet availability. We tested its reliability for converting speech to
text and got a “word error rate” (WER) of less than 5%. We tested its
functional usability and got a score of more than 71% on the system usability scale (SUS). The survey
showed a favorable response of 70 plus % in reducing reckless driving via CRP
in RCS if aided with mobile apps.

Published: July 2020

Flood is considered to be a major natural disaster occurrence that affects human existence and the environment in many parts of the world. The objective of this study is to analyze the flood-prone areas and determine their spatial locations using GPS and also determine the causes of flooding in the study area through questionnaires. To achieve this, primary source data like fieldwork was used and secondary source data like administration of questionnaires was also used. A Survey of 120 randomly sampled respondents was conducted in different flood-prone locations and 100 responded. The data obtained from the questionnaires was analyzed for the determination of the flood-prone areas in Ota, Ogun State. The result reveals that human activities like the dumping of refuse in drainage, bad road network, lack of proper drainage is majorly responsible for the areas to be at risk of flood prone. It was recommended that the government should create public awareness and sensitization campaigns should be embarked on to prevent the occurrence of this hazardous event in the future.
Coalizões Internacionais, Países em Desenvolvimento e Política Doméstica nas Negociações do Gatt/WTO / The Internationals Coalitions, Developing countries and the Domestic Policy in the negotiations from Gatt/WTO
Authors: Lima Thiago , Cepaluni Gabriel
Published: July 2020

O debate recente sobre coalizões de países em desenvolvimento no GATT/WTO, estimulado em grande parte pelo livro de Narlikar (2003), tem negligenciado a importância das políticas domésticas para o resultado das negociações em instituições de comércio. Neste artigo, argumentamos que o entendimento das políticas domésticas é condição necessária, embora não suficiente, para explicar os resultados de barganhas entre países ricos e coalizões de países em desenvolvimento. Nesse sentido, duas condições, não mutuamente excludentes, influenciam os desempenhos das coalizões internacionais: (1o) país ou países poderosos contrários às coalizões analisadas que buscam fragmentar os interesses domésticos das nações participantes dessas coalizões; e (2o) coalizões de países em desenvolvimento que buscam influenciar a política doméstica do país ou das nações mais poderosas que a elas se contrapõem. Para sustentar nossos argumentos, analisaremos dois casos de coalizões internacionais: a Campanha de Acesso a Medicamentos contra o HIV/Aids e o Grupo dos 20 (G-20).  The current debate about Coalitions of Developing Countries in the GATT/WTO was stimulated, largely, in the Narlikar´s book (2003) have neglected the importance fromthe domestic policies to the result of the negotiations in trade institutions. In this article, we argue that the understanding from domestic policies is the requisition, but not enough, to explain the results of the political bargains between rich countries and coalitions between developing countries.  In this way, there are two conditions, not mutually excluding, influencing the performances of Internationals Coalitions: (1º)  One or more powerful Countries that are  against these alliances search disintegrate the domestics interests from the participators Nations from these union; (2º) Alliance from developing countries seeking to influence the domestic policy from country or from more countries that are against it. To support our argument, we will analyze two cases of internationals coalitions: The Access to Medicines Campaign against to HIV/Aids and The Group 20 (G-20).
Guerra / War
Authors: Emerson Ralph Waldo
Published: July 2020

O texto traz uma visão histórica da guerra, mas do ponto de vista da diminuição dos conflitos no tempo e da busca pela paz. Segundo o autor, a tendência à guerra é gradualmente substituída pela tendência à paz, na medida da evolução e do amadurecimento do homem, que aos poucos abandona o instinto primitivo de autopreservação, que é a verdadeira função da guerra. Esse instinto de guerra pode ser mitigado por outros instintos, que podem modificá-lo ou controlá-lo e, até mesmo, domá-lo por completo. Além disso, o sentimento de moral, o comércio e o esclarecimento são outros meios para se chegar à paz, pois o primeiro faz perceber o lado animalesco do conflito; o segundo as semelhanças entre as pessoas; e o terceiro dá o conhecimento ao homem de que a história é o registro da diminuição da guerra. Dessa forma, com a promoção desses três elementos, os homens seriam levados a buscar a paz e evitar a guerra. Por fim, o projeto de paz deve ser feito por cada homem em particular, uma vez que a conquista do instinto de guerra é própria de cada pessoa.The text brings a historic vision of war, but focusing on the reduction of conflicts through time and the seek for peace. According to the author, the trend of war is gradually substituted by the trend toward peace as the mankind evolves and matures, that slowly dumps its primitive instincts of autopreservation, at which is the true function of war. This instinct of war might be mitigated by others insticts, that may modify or control and even completely tame it. Futhermore, the moral feeling, the trade system and the enlightment are either means to reach peace, since the first enables the perception of the animalistic side of conflict, the second enables the people's resemblances, and the third provides mankind the knowlegde that history is the registry of the decreasing of war. In that way, promoting theses three elements, the mankind would be lead to seek peace and avoid war. At the end, the peace project should be done by the individual in particular, since the instintict of war is conquered by every person itself.

The fact that the legal aid provision has not reached all the Indonesian citizens forces the Ministry of Law and Human right to establish the ministerial regulation of the Ministry of Law and Human Right No. 1 year 2018 about Paralegal on legal aid provision which is effectively applied on the 26th January 2018 as the implementation of Act No. 16 year 2011 about Legal Aid. The regulation that gives the Paralegals a spacious room to lawyer in the court resulted in pros and cons if it is contrasted to the position of an advocate within the act No. 18 year 2003 about lawyer, legal aid quality, and monitoring on the provision of legal aid. The statement of the problem is how the legal standing of Paralegal in lawyering in the court as what has already been regulated by the regulation of the Ministry of Law and Human Right No. 1 year 2018. This is a normative research with legislation approach and concept approach. The result of this research found out that there are Paralegal regulations that need to be adjusted with the regulation about legal aid provision such as age limit, qualiﬁ ed educational curriculum, and the need of ethical code that ties up the Paralegal joining law aid organization, so the objective of this constitutional nation to admit, to protect, and to guarantee the human right of the citizens about the access to justice and equality before the law as what has been explained in Article 28 D, article 4 point (1) Constitution of Indonesian Republic Year 1945 could be implemented.

This article discusses process Letter of Determination of Conﬁ scation of Execution without being based on a judge's decision that granted conﬁ scation of collateral in case No. 332/Pdt.G/2016/ PN.Jkt.Sel and the legal consequences of the party executed by the Execution Seizure determined by the head of court in case No. 332/Pdt.G/2016/PN.Jkt.Sel, when the decision has been legally binding it is still associated with the principle of legal certainty in the HIR. The research method used in this thesis is normative juridical which puts forward secondary data by completing primary data in the form of interviews with informants. With analytical analytics, secondary data and primary data are analyzed qualitatively. The results of this research indicate that the determination of the conﬁ scation of execution issued by the chairman of the Court in case No. 332/Pdt.G/2016/PN.Jkt.Sel is valid, if it is related to Article 227 HIR that a decision has permanent legal force, the winning party may submit a seizure of execution conﬁ scation that was never previously stipulated in the decision and the legal consequences against Determination of execution, namely the Defendant's assets must be conﬁ scated in accordance with the determination of the execution for the beneﬁ t of the Plaintiff for the sake of legal certainty as the party won.

Mother-Tongue Theology: Akan Christian Christological Re-interpretations
Authors: Ahaligah Aidan Kwame
Published: July 2020

The importance of the mother tongue in the planting and growth of African Christianity has been stressed by scholars such as Lamin Sanneh and Kwame Bediako. Bediako, for instance, states that “the ability to hear in one’s language and to express in one’s language one’s response to the message which one receives, must lie at the heart of all authentic religious encounters with the divine realm.” The paper discusses how the translation of the Bible and the use of the mother-tongue—has facilitated the production of new theological idioms by Akan Pentecostals/Charismatics in particular and Christians in general. Particularly, the paper discusses how the use of the mother-tongue has contributed to the re-interpretation of classical theological concepts such as Christology. Christ as an Ancestor and Christ as Healer-Duyefo is among the topics to be discussed in this paper. Keywords: Mother-Tongue Hermeneutics, Akan, African Christology, Pentecostal-Charismatic, Translation, Gospel.
Detailed Model of the Growth of Fluffy Dust Aggregates in a Protoplanetary Disk: Effects of Nebular Conditions
Authors: Xiang C. , Matthews L. S. , Carballido A. , Hyde T. W.
Published: July 2020

The coagulation of dust aggregates plays an important role in the formation of planets and is of key importance to the evolution of protoplanetary disks (PPDs). The characteristics of dust, such as the diversity of particle size, porosity, charge, and the manner in which dust couples to turbulent gas, affect the collision outcome and the rate of dust growth. Here we present a numerical model of the evolution of the dust population within a PPD which incorporates all of these effects. The probability that any two particles collide depends on the particle charge, cross-sectional area, and their relative velocity. The actual collision outcome is determined by a detailed collision model that takes into account the aggregate morphology, trajectory, orientation, and electrostatic forces acting between charged grains. Our model is applicable to the epoch of time during which hit-and-stick is the primary collision outcome, the duration of which varies greatly depending on the environment. The data obtained in this research reveal the characteristics of dust populations in different environments at the end of the hit-and-stick growth, which establishes the foundation for the onset of the next growth stage where bouncing, mass transfer, and fragmentation become important. For a given level of turbulence, neutral and weakly charged particles collide more frequently and grow faster than highly charged particles. In general, the epoch of hit-and-stick growth is much shorter in high turbulence than it is in regions with low turbulence or highly charged grains. In addition, highly charged particles grow to a larger size before reaching the bouncing barrier, especially in environments with low turbulence, and exhibit “runaway” growth, in which a few large particles grow quickly by accreting smaller particles while the rest of the population grows very slowly. In general, highly charged aggregates have a more compact structure and are comprised of larger monomers than neutral/weakly charged aggregates. The differences in the particle structure/composition not only affect the threshold velocities for bouncing and fragmentation, but also change the scattering and absorption opacity of dust, influencing the appearance of PPDs.
70 Years of Chromospheric Solar Activity and Dynamics
Authors: Bertello Luca , Pevtsov Alexei A. , Ulrich Roger K.
Published: July 2020

From 1915 to 1985 the monitoring program of the Mount Wilson Observatory, one of the Observatories of the Carnegie Institution of Washington, has taken over 35,000 daily images (spectroheliograms) of the Sun in the chromospheric resonance line of Ca ii K. This important database constitutes a unique resource for a variety of retrospective analyses of the state of solar magnetism on multidecadal timescales. These observations may also hold the key for untangling some of the mysteries behind the solar dynamo, which in turn could result in a better predictive capability for current dynamo models. We describe here a procedure to calibrate and rescale these images so that homogeneous Carrington synoptic maps can be derived for the whole period covered by these observations. Temporal variations in full-disk chromospheric activity clearly show the signature of the 11 yr solar cycle, but no evidence is found for a statistically significant north/south hemispheric asymmetry. Using a feature-tracking technique we were also able to obtain the average solar rotation profile. We find no indication of any detectable periodicity in the temporal behavior of the orthogonalized rotation rate coefficients, suggesting the global chromospheric dynamics has not changed during the 70 years investigated in this work. We found also no significant evidence in our analysis for a hemispheric asymmetry in rotation rates.
Global 21 cm Signal Extraction from Foreground and Instrumental Effects. III. Utilizing Drift-scan Time Dependence and Full Stokes Measurements
Authors: Tauscher Keith , Rapetti David , Burns Jack O.
Published: July 2020

When using valid foreground and signal models, the uncertainties on extracted signals in global 21 cm signal experiments depend principally on the overlap between signal and foreground models. In this paper, we investigate two strategies for decreasing this overlap: (i) utilizing time dependence by fitting multiple drift-scan spectra simultaneously, and (ii) measuring all four Stokes parameters instead of only the total power, Stokes I. Although measuring polarization requires different instruments than are used in most existing experiments, all existing experiments can utilize drift-scan measurements merely by averaging their data differently. In order to evaluate the increase in constraining power from using these two techniques, we define a method for connecting root-mean-square (rms) uncertainties to probabilistic confidence levels. Employing simulations, we find that fitting only one total power spectrum leads to rms uncertainties at the few K level, while fitting multiple time-binned, drift-scan spectra yields uncertainties at the ≲10 mK level. This significant improvement only appears if the spectra are modeled with one set of basis vectors instead of using multiple sets of basis vectors that independently model each spectrum. Assuming that they are simulated accurately, measuring all four Stokes parameters also leads to lower uncertainties. These two strategies can be employed simultaneously, and fitting multiple time bins of all four Stokes parameters yields the most precise measurements of the 21 cm signal, approaching the noise level in the data.
A Search for Lensed Gamma-Ray Bursts in 11 yr of Observations by Fermi GBM
Authors: Ahlgren Björn , Larsson Josefin
Published: July 2020

Macrolensing of gamma-ray bursts (GRBs) is expected to manifest as a GRB recurring with the same light curve and spectrum as a previous one, but with a different flux and a slightly offset position. Identifying such lensed GRBs may give important information about the lenses, the cosmology, and the GRBs themselves. Here we present a search for lensed GRBs among ∼2700 GRBs observed by the Fermi Gamma-ray Burst Monitor during 11 yr of operations. To identify lensed GRBs, we perform initial cuts on position, time-averaged spectral properties, and relative duration. We then use the cross-correlation function to assess the similarity of light curves, and finally we analyze the time-resolved spectra of the most promising candidates. We find no convincing lens candidates. The most similar pairs are single-pulsed GRBs with relatively few time bins for the spectral analysis. This is best explained by similarities within the GRB population rather than lensing. However, the null result does not rule out the presence of macrolensed GRBs in the sample. In particular, we find that observational uncertainties and Poisson fluctuations can lead to significant differences within a pair of lensed GRBs.

The uncharted territory of the high-redshift (z ≳ 3) universe holds the key to understanding the evolution of quasars. In an attempt to identify the most extreme members of the quasar population, that is, blazars, we have carried out a multiwavelength study of a large sample of radio-loud quasars beyond z = 3. Our sample consists of nine γ-ray-detected blazars and 133 candidate blazars selected based on the flatness of their soft X-ray spectra (0.3–10 keV photon index ≤1.75), including 15 with Nuclear Spectroscopic Telescope Array (NuSTAR) observations. The application of the likelihood profile stacking technique reveals that the high-redshift blazars are faint γ-ray emitters with steep spectra. The high-redshift blazars host massive black holes (

) and luminous accretion disks (

erg s−1). Their broadband spectral energy distributions are found to be dominated by high-energy radiation, indicating their jets are among the most luminous ones. Focusing on the sources exhibiting resolved X-ray jets (as observed with the  Chandra satellite), we find the bulk Lorentz factor to be larger with respect to other z > 3 blazars, indicating faster moving jets. We conclude that the presented list of high-redshift blazars may act as a reservoir for follow-up observations, such as with  NuSTAR, to understand the evolution of relativistic jets at the dawn of the universe.
