Vision is the science that informs us about the biological and evolutionary algorithms that our eyes, opticnerves and brains have chosen over time to see. This article is an attempt to solve the problem of colour to grey conversion, by borrowing ideas from vision science. We introduce an algorithm that measures contrast along the opponent colour directions and use the results to combine a three dimensional colour space into a grey. The results indicate that the proposed algorithm competes with the state of art algorithms.

In this article the optimization of a realistic oil and gas separation plant has been studied. Two different fluids are investigated and compared in terms of the optimization potential. Using Design of Computer Experiment (DACE) via Latin Hypercube Sampling (LHS) and rigorous process simulations, surrogate models using Kriging have been established for selected model responses. The surrogate models are used in combination with a variety of different evolutionary algorithms for optimizing the operating profit, mainly by maximizing the recoverable oil production. A total of 10 variables representing pressure and temperature various key places in the separation plant are optimized to maximize the operational profit. The optimization is bounded in the variables and a constraint function is included to ensure that the optimal solution allows export of oil with an RVP < 12 psia. The main finding is that, while a high pressure is preferred in the first separation stage, apparently a single optimal setting for the pressure in downstream separators does not appear to exist. In the second stage separator apparently two different, yet equally optimal, settings are revealed. In the third and final separation stage a correlation between the separator pressure and the applied inlet temperature exists, where different combinations of pressure and temperature yields equally optimal results.<br>

         الملخّصتحاول هذه الدراسة، التي أحسب أنها الأولى من نوعها، أن تقدم مقارنة تحليلية للإرث الفكري للشيخين محمد عبد الوهاب (1703-1791م) في الجزيرة العربية وشاه ولي الله الدهلوي (1703-1761م) في شبه القارة الهندية في إطار واقعهما البيئي. وتخلص إلى أن لفظ "الوهابية الهندية"، الذي ابتدعه بعض المستشرقين لوصف حركة الإصلاح الإسلامي في الهند، والذي يوحي بأن رائدها الدِّهلوي كان مجرد نسخة مطابقة لمعاصره ابن عبد الوهاب، مصطلح غير دقيق، بل لعله خاطئ كليًّا. وذلك لأن دراسة الإرث الفكري لهذين العملاقين تبين بأنهما أسسا في عصر ما قبل الهجمة الإستعمارية على بلاد المسلمين مدرستين متباينتين من حيث التوجه والمحتوى.الكلمات المفتاحية: محمد عبد الوهاب، شاه ولي الله، الإرث الفكري، التجديد الإسلامي. Abstract          This is the first study to provide an analytical comparison of the intellectual legacy of two great scholars Muhammad ibn ‘Abd al-WahhÉb (1703-1791) in the Arabian Peninsula and Shah WalÊ Allah DehlawÊ (1703-1761) in the Indian sub-continent in the context of their respective environments. It concludes that the term “Indian Wahhabism”, which was coined by some Orientalists to describe the movement for Islamic reform in India, suggesting that Sheikh DehlawÊ was just a duplicate of contemporary Ibn ‘Abd al-WahhÉb, is not only inaccurate but completely incorrect. The study of the intellectual legacy of these two luminaries reveals that they both founded, prior to the pre-colonial attack on the Muslim world, two schools different in terms of orientation and content..Keywords: Muhammad ibn ‘Abd al-WahhÉb, ShÉh WalÊ Allah DehlawÊ, Intellectual Heritage, Islamic Revival.
