Comparison of Steganography Using the Discrete Cosine Transform Method on Image Based Bilinear, Nearest Neighbor and Spline Interpolation

The research was conducted in the field of steganography. Discrete Cosine Transform (DCT) is a method used in the insertion technique. The results of steganography have problems if they look blurry, have low levels of similarity and high error values. One way to solve this problem is by proposing image interpolation. The interpolation method consists of various kinds and gives each other advantages. This study intends to compare three kinds of interpolation techniques to find the best one. The three interpolation techniques are bilinear, nearest neighbor, and spline. The method used in this research is experimental. Images with extension formats * .tif, * .png, and * .bmp with dimensions of 512x512 px are interpolated by scaling 1.5, 2, and 4. The results of the interpolation process are used to insert messages in * .txt format of 157 bytes with discrete cosines transform (DCT). The image quality of the message insertion is measured by the MSE and PSNR values. The result of the message insertion test shows that the value of the image quality is directly proportional, meaning that if the condition of the message size is fixed and the cover dimensions are greater, the MSE value will be smaller and the PSNR value will be greater. Images with * .tif and * .bmp extension formats have good stability, * .png images vary in size. The smallest error value test results were obtained in the spline interpolation technique and this method when compared to the other two techniques had the lowest average MSE value of 8.221 and the PSNR value of 40,301 dB.
Lossless compression with state space models using bits back coding

We generalize the 'bits back with ANS' method to time-series models with a latent Markov structure. This family of models includes hidden Markov models (HMMs), linear Gaussian state space models (LGSSMs) and many more. We provide experimental evidence that our method is effective for small scale models, and discuss its applicability to larger scale settings such as video compression.

Political representation and the right of recall: A proposal

In a representative democracy, members of parliament should be accountable to the voters who elected them. For this to be actually the case, the latter require an instrument of deterrence, a mechanism of control over opportunistic representatives, for example the right to recall them at any moment. However, two obstacles, one ideological and one practical, hinder legal recognition of this right. The first is due to the doctrine by which members of parliament legislate in the public interest, and therefore should not be constrained by a mandate binding them to their particular voters. The second consists in the fact that voting secrecy hinders the identification of which voters elected any one member of parliament. In this article, leveraging the potential offered by modern Information and Communication Technologies (ICT), I propose a model for an electoral system that dissolves the first problem and resolves the second. According to my model, electoral platforms constitute the formal instructions by which members of parliament are held accountable, and an electronic vote makes it possible to associate each member of parliament with his or her voters while still guaranteeing voting secrecy. Voters are then able to participate in a process of deliberation about the decisions made by their representative and may revoke their mandate if the representative fails to comply with it.
Analisis Efektifitas Pembelajaran Daring Siswa Kelas IX C SMP N 6 Tabanan Pada Saat Pandemi Covid 19

The Covid-19 pandemic has forced the learning system in schools to change drastically from face-to-face meetings to online learners. No exception SMP N 6 Tabanan also conducts online learning with various online applications including schoology, google classroom, google form, whatsapp group and other media. This study aims to analyze the effectiveness of online learning that was carried out during the Covid-19 Pandemic. This study used a survey method using a questionnaire which was conducted online. The test results found that online learning was less effective and directly proportional to students' lack of understanding in learning. The effectiveness of online learning during the Covid-19 pandemic, namely by using the google classroom application and the learning model using modules / books held by students and the types of assignments that can be understood by students are multiple choice question assignments. The media used by students for online learning almost all students use gadgets (HP) and the obstacles faced by students in online learning are constraints from limited data quotas and slow internet networks.

Using machine learning workflows to identify seafloor massive sulfides based on disparate geophysical data

Many current research questions in Earth Sciences are related to understanding the complex geological processes that dictatethe location of resource formation. Multivariate and multi-disciplinary measurements across disparate spatial scales are common and generate databases that cross traditional geoscientific domains such as geophysics, geochemistry and geology. To cope with this mass of information, integrative data assessment approaches are essential for optimal information extraction from the available data, enabling more accurate prognoses of where to find previously undiscovered natural resources. This is especially true in the deep ocean, where data collection is inherently more difficult than on land. Here, we present an example from predicting the spatial distribution of seafloor massive sulfides (SMS) at the Trans-Atlantic Geotraverse (TAG) hydrothermal field using various sources of marine geophysical data, including high-resolution bathymetry and magnetics collected with an autonomous underwater vehicle (AUV), as well as conductivity data derived from Controlled-Source Electromagnetic (CSEM) measurements. Electrical conductivities are considered a direct SMS indicator as these exhibit a substantial conductivity variation to the surrounding host rock. Due to the size of the survey area, a spatial sampling of conductivity on a dense grid is not economical and would require many years of data acquisition. As a result, robust extrapolation of sparsely sampled conductivity data onto a regional scale seems efficient for predicting additional occurrences of SMS by integrating the acquired marine geophysical data into a Data Science framework. We show that this framework may improve current SMS predictions through associated prediction uncertainty, thereby detecting observational gaps and informing further sparse sampling of ground.truthing data (e.g. sampling or visual observations).
