Rectangle-Based Neo-Plasticism-Like Image - A New Type of Art Image and its Application to Covert Communication

A new type of art image, called rectangle-based Neo-Plasticism-like image, is proposed, via which messages can be hidden for covert communication. Also proposed is an automatic method for creating such art images, which applies recursive binary partitioning to a source image by finding the maximum mutual information of the spatial positions and image intensities of the divided sub-regions. The resulting image consists of rectangular regions separated by horizontal and vertical lines, which show the abstraction style of the Neo-Plasticism art. Attracted by the artistic image content, a hacker hopefully will pay no attention to the hidden secret. Two data hiding techniques based on the binary partition tree constructed in the art image creation process are proposed, which embed messages by replacing the LSBs of each rectangular region's colors or by generating additional partition lines in the region. A message extraction process is also proposed. Data security is considered seriously by randomizing the message bits before being embedded, changing randomly the priorities of the sub-regions used in message hiding, and embedding fake messages to interfere with the hacker. Good experimental results show the feasibility of the proposed techniques for covert communication via the proposed type of art image.
Combining Indigenous and Scientific Forecast for Improved Climate Services in Ghana

&amp;lt;p&amp;gt;Extreme weather events and climate change are affecting the livelihoods of farmers across the globe. Accessible and actionable weather and seasonal climate information can be used as an adaptation tool to support farmers to take adaptive farming decisions. There are increasing calls to integrate scientific forecast with indigenous forecast to improve weather and seasonal climate information at local scale. In Northern Ghana, farmers lament about the quality of scientific forecast information thereby depending on their own indigenous forecast for taking adaptive decisions. To improve this, we developed an integrated probability forecast (IPF) method to combine scientific and indigenous forecast into a single forecast and tested its reliability using binary forecast verification method as a proof of concept. We also evaluated the acceptability of IPF among farmers by computing an index from multiple-response questions with good internal consistency check. Results show that, for reliability, IPF on average performed better than indigenous and scientific forecast at a daily timescale. At seasonal timescale, indigenous forecast overall performed better followed by IPF and then scientific forecast. However, IPF has far greater acceptability potential. &amp;amp;#160;About 93% of farmers prefer IPF method as this provides a reliable forecast, requires less time and at the same time helps deal with contradicting forecast information. Results also show that farmers already use insights from both forecasts (complementary) to inform their farm decisions. However, their complementary method does not resolve the issues of contradicting forecast information. We conclude that, as a proof of concept, integrating indigenous and scientific forecast has high acceptability and can potentially increase forecast reliability and uptake.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;amp;#160;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;amp;#160;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;&amp;amp;#160;&amp;lt;/p&amp;gt;
A Novel Multilevel RDH Approach for Medical Image Authentication

Online healthcare is the next big thing and proper security mechanisms with privacy preservation techniques for sensitive data is the need of the hour. Handling sensitive datasets such as medical data needs ultimate security which covers confidentiality, integrity, authentication, and reversibility. This paper presents a novel approach for authentication using reversible data hiding (RDH) technique. Traditional RDH methods provide adequate security for sensitive image. The proposed RDH technique uses a combination of reversible data marking techniques in multiple levels to provide a robust authentication measure for medical images. Least significant bit (LSB) modification works as the base methodology for data marking to ensure complete reversibility.
Beyond mandates: for open science to become a norm, it must be recognised and rewarded

Calls to align incentives in academia to promote open research practices are not new. However, in recent years research funders are increasingly implementing policies and schemes designed to promote open science practices amongst researchers. In this post, Maria Cruz and Hans de Jonge outline details of the Dutch Research Council’s (NWO) new Open Science Fund, which they suggest is the natural next step towards a culture of open science in Dutch research.

Privacy Enhancing Technologies and Synthetic Data

Privacy enhancing technologies (PETs) are a set of technologies that assist organizations in protecting data. In addition to PETs, there are Transparency Enhancing Technologies (TETs) and Intervenability Enhancing Technologies (IETs). These technologies are complementary approaches to PETs. TETs are “tools which can provide to the individual concerned clear visibility of aspects relevant to [its personal] data and the individual’s privacy” (Zimmerman, 2015). While PETs work to minimize data, TETs provide users with information regarding the data handling behavior of third parties. IETs provide users opportunities to intervene and encompass control including giving, denying or withdrawing consent, and blocking or erasing personal data. IETs “aim[] at the possibility for parties involved in any privacy-relevant data processing to interfere with the ongoing or planned data processing (Karegar, 2018).” However, technologies associated with intervenability are currently limited. This paper will provide an overview of PETs and then further explore the specific PET of synthetic data sets technology.
Understanding the Real Problem of Fakes in Africa

Africa is rising: its growing middle and upper class represent an untapped, dynamic, fast-moving, and competitive market that businesses can scarcely ignore. Household consumption in Africa has increased faster than the continent’s gross domestic product (GDP), which itself has consistently outpaced the global average. Consumer expenditure is growing at a compound annual rate of 3.9 per cent since 2010, from US$1.4 trillion in 2015 to an expected $2.5 trillion by 2030. If one adds the importance of brand recognition to African buyers, the young and growing population, the rapid urbanization, and the spread of Internet and mobile phones on the continent, Africa’s emerging economies present exciting opportunities for rights holders.

Review and Redaction-Tolerant Image Verification Using Cryptographic Methods

Verification inspections that support nuclear weapon arms control treaties can require photographs to be taken as part of the inspection evidence. In a nuclear weapon facility, the host would generally want to review images before they are released to the inspector to prevent the accidental release of sensitive information. Currently, giving the host sole custody of the images for review severely impacts the confidence of the inspector that the images are genuine and unmodified. This paper outlines how simple cryptographic methods can be employed to allow the host sole custody for review while maintaining the inspector’s confidence in the veracity of the images. The concept is then expanded to propose and illustrate the capability for the host to redact a portion of an image while still allowing the inspector to verify that the remainder of the image is genuine. The ability to allow a host to have sole custody of images for review, and even redaction, without affecting inspector confidence in the veracity of the images they receive would contribute to improved processes for nuclear weapon verification in future arms control treaties.

One Word, Two Definitions: A Comparison of Word Definitional Skills between Monolingual and Bilingual Students

The purpose of this study was to expand the current literature on word definitions, to empirically investigate (a) the definitional skills, (b) the effect of grammatical category of the word and (c) the preferred definition types produced by Greek monolingual students and Turkish-Greek bilingual students of different levels of education.Previous research has shown that bilinguals produce better definitions than their monolingual peers due to their enhanced metalinguistic abilities.To date, no studies have compared the definitional skills considering word grammatical categories in bilingual students of different levels of education.To this end, 158 students -79 monolingual speakers of Greek and 79 bilingual speakers (L1 Turkish, L2 Greek) -were tested and were asked to define 16 words (8 nouns, 4 verbs, and 4 adjectives), orally.Definitions were scored on a five-point scale along a continuum that reflects the developmental path of the definitions.The findings indicated that monolinguals outperformed bilinguals in respect to the content of definitions in all grammatical categories, regardless of their level of education.Nevertheless, in form, the differences between the groups disappeared in senior high school.Bilingual students catch up their monolingual peers, conceivably, due to their enhanced metalinguistic abilities.The finding further supports that content of definitions is a more sensitive indicator.Within group comparisons have shown that the production of formal definitions exhibits in junior high school, while it takes more time for this pattern to emerge in bilinguals (i.e. in senior high school).Nouns were better defined than verbs and adjectives.Verbs and adjectives did not differ in upper elementary school students; however, a difference arose in junior high school, i.e. more formal definitions were used in adjectives compared to verbs, proving that verbs are more abstract and, thus, difficult to be defined.All in all, the present study offers useful insights about the development of word definitional skills considering word grammatical categories in bilingual and monolingual students of different levels of education and discusses the outcomes in the light of educational practices.

This study tried to identify the factors that have effects on the academic performances of university students in the Sylhet Region. Student’s perceptions were taken to determine the factors affecting academic performance. Independent t-test was used to find out the mean difference of academic results between two groups of students. Results showed that there is a significant difference between male and female students in the case of academic study time and CGPA; as the female students have higher CGPA than male students by utilizing most of the academic study time. To find out the effective factors, the result showed that students who attend class regularly, feel comparatively less academic stress, submit assignments in due time and spend more time for the academic study were found to have higher academic marks compared to others who do not. By assessing other factors, results showed the students coming from the nuclear family got good marks rather than the extended family. Besides, the students having sufficient access to healthy food, satisfied with the current accommodation level had good academic marks, and students who spent more time in unproductive activities got poor marks in academics. Improving these factors would also influence much of the academic success of students.
SISTEM PAKAR PENYAKIT KARET MENGGUNAKAN METODE FORWARD CHAINING PADA PERKEBUNAN PT.WANAMUKTI WISESA TEBO

Rubber disease is often referred to as OPT (Plant Destruction Organisms) found in rubber plants which cause losses to farmers which interfere with growth and production. The lack of knowledge of rubber farmers about pests (Plant Destruction Organisms) on rubber plants caused significant losses so an expert system was created to diagnose rubber plant diseases using the forward chaining method to obtain the certainty value of a symptom experienced by rubber plants against a disease. The determination of rubber plant disease in this expert system is carried out through a consultation process between the system and the user. The system will display the symptoms of rubber plants by selecting yes / no. Symptoms that are selected by the user will be adjusted to the existing rules so that the user will get the results of disease diagnosis and control. The results of the analysis and evaluation show that the expert system uses this forward chaining approach, reasoning in the expert system starts based on the information provided by the user in the form of existing facts, then the hypothesis is sought based on the facts and existing rules.
Mobile Robot Path Navigation in Static Indoor Environment via AOR 9-Point Laplacian Iteration Numerical Technique

Mobile robot path navigation is a crucial subject in robotics research and development. The navigation efficiency of a robot correlates directly with its overall performance. With persistent technological growth, the improvement potentials for autonomous robotic remains vast. The objective of this paper is to investigate the performance of the iteration technique called Accelerated Overrelaxation 9-Point (AOR-9P) Laplacian in enabling path navigation for mobile robots. This technique is a derivation from Laplace's equation which is used to calculate the potential fields in the 2-dimensional configuration space representation of an environment. The robotic path navigations are performed in a simulation called Robot 2D Simulator, written in Delphi Project software. After obtaining the solutions generated through AOR-9P iterative technique, the Gradient Descent Search (GDS) technique is employed to determine the best path for the mobile robot to traverse on. The performance of AOR-9P is examined by comparing the number of iterations needed to complete the navigation process. Results shown that AOR-9P enabled path navigation requires the least number of iterations to complete, thus having better performance than its predecessor techniques. In the same time, the paths produced are generally smooth and unobstructed all the way towards the goal point. For future improvements, it is recommended that the Half-Sweep (HS) and Quarter-Sweep (QS) approach to be introduced on AOR-9P iteration technique to improve its performance in solving the mobile robot path navigation problem
