<em>This paper proposed a discrete cosine transform least significant Bit-2 steganography encryption method for embedding the secret data in the cover image. The method overcomes physical signs of pixel modifications while achieving a high data payload. This technique enables data to be hidden in a cover image, while the image recognition artificial neural network checks the presence of any visible alterations on the stego-image.

Abstract:
Abstract—Steganography is a vital technique in information security that conceals data within other non-secret data, primarily images. This paper explores four prominent image steganography techniques: Least Significant Bit (LSB), Pixel Value Differencing (PVD), Discrete Cosine Transform (DCT), and Masking &amp; Filtering. Each method is examined in terms of its operational principles, advantages, and limitations. LSB is straightforward but vulnerable, while PVD offers higher capacity and robustness. DCT enhances resistance against compression, and Masking &amp; Filtering maintains high image

Abstract:
A Digital watermarking is a technique that provides a solution to the longstanding problems faced with copyrighting digital data. Digital watermarks are pieces of information added to digital data (audio, video, or still images) that can be detected or extracted later to make an assertion about the data. This information can be textual data about the author, its copyright, etc; or it can be an image itself. Watermarking Based on DCT Coefficient Modulation technique embeds the watermark in the DCT domain to increase the robustness of the watermarking scheme.DCT based watermarking is an example

In this article, a combined Discrete Cosine Transformation (DCT) and Successive Division based image watermarking scheme is proposed. In many spatial domain approaches, the watermark information is embedded into Least Significant Bits (LSBs) of host image. These LSBs are more vulnerable to noise and other unwanted information contents in the channel, in few cases these are subjected for modifications also. Many frequency domain approaches withstands LSB interference problem but utilizes more execution time. The proposed technique is a frequency domain approach which can withstand LSB attack an

Evidence to date suggests that psychedelics can be given safely in controlled conditions, at moderate to high doses, and may have potential as therapeutic agents in the treatment of various addictive and mood disorders.

Abstract:
Abstract Two test labs working for a seamless pipe manufacturer launched a test program to better evaluate the DCB test variability and to understand the factors of variation. The objective was to be able to give the same KISSC values independently of the testing lab. Testing labs A and B evaluated their initial differences through inter-laboratory testing, selected the factors of variations and used an original Taguchi design of experiment approach that allowed the investigation of a quite large number of factors within a limited number of tests. Among the selected factors, variations of the

Abstract:
Abstract The presence of H2S in well fluids imposes severe restrictions on the use of tubular goods because of sulfide stress cracking (SSC). Increasing developments of deep sour wells require high strength OCTG with improved SSC resistance. The appropriate selection of materials for well completion is an important factor in economic success of oil and gas production. Corrosion cracking behaviour of metals for the range of environments expected in service is the main criterion. Such knowledge is gained partly from service experience, but mainly from appropriate laboratory testing at the design

Abstract:
Corrosion and materials performance are key considerations in the practical design and operation of Carbon Dioxide capture and storage (CCS) systems. Materials resistance to H2S-related cracking is a mature area with guidance provided in NACE MR0175/ISO 15156. However, dense phase CO2 in equilibrium with free water results in extremely low pH values, below typically evaluated regions of sour performance. Benchmarking study of sour cracking behavior in CCS environment is required with the focus on wells high strength materials. In the study, thermodynamic calculation of H2S level in both CO2 ri

Abstract:
Abstract Dissolved H2S in the produced fluid degrades the performance of Oil Country Tubular Goods (OCTG) steels by leading to Sulfide Stress Cracking (SSC). Direct material evaluation or Fit-For-Service (FFS) testing at high reservoir pressure is challenging. Alternative is to reproduce appropriate dissolved hydrogen sulfide (H2S) level to perform tests in lab at lower pressures. In general, Oil and Gas (O&amp;G) industry uses partial pressure of H2S to define the FFS test conditions. However, sour gas mixtures exhibit non-ideal behaviors at high system pressure. Neglecting these non-ideal ef

Den 15-19 maj 2022 medverkade Agtech 2030, genom undertecknad, i en delegationsresa till Israel. Resan var kulmen på olika aktiviteter under 3 års tid. En milstolpe skedde 2019 då vi fick ett brev från Israels ambassadör Ilan Ben-Dov, som resultat av en artikel vi hade skrivit på DN Debatt. Sedan dess har analyser och dialoger genomförts med tema Israel/Agtech. Syftet med resan som nu äntligen blev av var att ge ett keynoteföredrag, delta i diskussioner med svenska och israeliska företag samt göra studiebesök i innovationsmiljöer.

Abstract:
The digital twin used in this research is a mechanistic (or deterministic) computer model that represents the cathodic protection behavior of a pipeline network. The model is calibrated based on field data such that it mimics the real-world behavior of the pipeline. The objective of this research is to validate the accuracy of the digital twin model on three industry cases. First, the sensitivity of the independent variables (soil, coating and cathodic protection properties) that are the inputs of the digital twin was investigated during a literature study, a lab and field-based modeling on a
