The current paper proposes a novel scheme for non-blind watermarking of images, making use of discrete wavelet transform (DWT), discrete time Fourier transform (DTFT), as well as singular value decomposition, or SVD. During the process of embedding, 1-level DWT is used to decompose the host image into its various frequency sub-bands. After this, the high-frequency sub band receives an application of DTFT. This is followed then by SVD, after which the watermark becomes embedded into the now-transformed host image's singular matrix. Then, the inverses of 1-level DWT, DTFT and SVD are applied in order to obtain a watermarked final image. This paper evaluates the performance of the proposed method of watermarking against a number of attacks, including sharpening, salt and pepper noise, AWGN, gamma correction, histogram equalisation, flipping and cropping. Results obtained during experiments have found that the scheme as proposed does provide high levels of robustness and imperceptibility against various signal processing attacks.

With regard to oil production in Libya, the following instruments are particularly important:

- Sustainability guidelines

- Risk analyses

- Eco-efficiency analyses

- Balanced scorecards -

Key sustainability criteria (KPI)

- Certification systems

Sustainability consists of the balance between economic efficiency/economics on the one hand and ecology/environmental compatibility on the other. 15 Sustainable energy systems are always geared to demand. Energy is just one resource among many.

Employees, raw materials, knowledge, etc. are also important resources that need to be managed sustainably and a balance found. A system that is only one-sidedly focused on profit maximization or social compatibility

Examining what has led Libya to adopt international accounting standards (IASs)

This paper discusses the elements of popular culture in The Great Gatsby by F. Scott Fitzgerald. It highlights how the novel reflects the social and cultural atmosphere of the 1920s in America, particularly the rise of materialism, the pursuit of pleasure, and the decline of moral values. Through its depiction of jazz music, fashion, parties, cars, and the obsession with wealth, the novel serves as a mirror of the Jazz Age. The study concludes that The Great Gatsby is not only a literary masterpiece but also a cultural document that captures the spirit of its time and the contradictions within the American Dream.
