Phase Inversion Process

Porous asymmetric PVDF membranes were prepared by the phase inversion process induced by a nonsolvent. The effect of pore-forming hydrophilic additives on the membrane morphology and transport properties was investigated. It was found that membranes prepared with hydrophilic polymer additives can offer higher pure water flux, higher porosity and lower pepsin rejection. PEG 10 000 can be used as a good pore forming additive to prepare PVDF membrane with higher pure water flux and relatively high pepsin rejection.

Refined Palm Oil

An explosive growth of interest has been developed in creating of alternative process of crude palm oil wastewater treatment. Membrane processing offers many advantages as it can be used in almost the stage of oily wastewater treatment. Aim of this study was to investigate nanoporous membrane morphology and performance for refined palm oil wastewater treatment. The comparison of performance and morphology was carried out between neat PVDF and PVDF nanoporous membranes with nanosized TiO2particles of different compositions. Results of permeability and instrumental analysis illustrated that nanometer size obviously affected the PVDF membranes performance and structure. Smaller nanoparticles could improve the antifouling property of PVDF membrane more remarkably. Cross-section of membranes were observed with a field electronic scanning electron microscope (FESEM). The TiO2/PVDF membrane with smaller nanoparticles had smaller mean pore size on its surface and more apertures inside the membrane. X-ray diffraction (XRD) experiment was also suggested that the addition of 1.0 % TiO2nanoparticles had stronger effect on crystallization of PVDF molecules, poresize of 34.05 nm, contact angle of 53oand flux of 88.50 L/m2h of poresize. It can be concluded that nanoporous PVDF membrane with adding of TiO2has better performance for treating refined palm oil wastewater.

The inheritance and innovation of ancient architecture decoration art is an important way for the development of the construction industry. The data process of traditional ancient architecture decoration art is relatively backward, which leads to the obvious distortion of the digitalization of ancient architecture decoration art. In order to improve the digital effect of ancient architecture decoration art, based on neural network, this paper combines the image features to construct a neural network-based ancient architecture decoration art data system model, and graphically expresses the static construction mode and dynamic construction process of the architecture group. Based on this, three-dimensional model reconstruction and scene simulation experiments of architecture groups are realized. In order to verify the performance effect of the system proposed in this paper, it is verified through simulation and performance testing, and data visualization is performed through statistical methods. The result of the study shows that the digitalization effect of the ancient architecture decoration art proposed in this paper is good.

Content Generation

AbstrakPerkembangan game pada saat ini berkembang dengan sangat cepat, dalam perkermbangan game topik AI adalah topik yang paling banyak diteliti oleh beberapa peneliti khususnya pada pembuatan suatu konten game menggunakan metode PCG (procedural content generation). Pada pembuatan sebuah game world menggunakan metode PCG sudah banyak developer game yang sukses dengan mengimplementasikan metode ini, metode ini banyak digunkan pada geme dengan genre RPG, Rouglikes, Platformer, SandBox, Simulation dan lain sebagainya, Pada penelitian ini berfokus pada pengembangan sebuah game world generator untuk game berjenis open world yang berupa sebuah kepulauan dengan metode PCG dengan menggunakan algoritma perlin noise sebagai algoritma pembentuk textur utama pulau yang dimana pada penelitian ini memanfaatkan beberapa variable noise seperti octave, presistance dan lacunarity guna untuk menambah kontrol dari hasil textur yang dihasilkan serta algoritma penempatan pulau untuk membuat sebuah game world yang menyerupai sebuah kepulauan. Dari hasil uji generator terkait degan pengujian playability dan performa dapat disimpulkan bahwa generator yang dikembangkan playable serta performa yang dianaliasa menggunakan notasi Big O menunjukkan  (linear). Abstract Game development is currently growing very fast, game development AI is the most discussed topic by most researchers especially in the developing of game content using the PCG (procedural content generation) method. In making a game world using the PCG method, many game developers have succeeded by implementing this method, this method is widely used on RPGs, Rouglikes, Platformers, SandBox, Simulations and ect,. This study focuses on developing a game world generator game for open world type games in the form of an archipelago using the PCG method using the noise perlin algorithm as the island's main texturizing algorithm which in this study utilizes several noise variables such as octave, presistance and use for add control of the texture results as well as the island placement algorithm’s to create a game world that resembles an archipelago form. From the generator test results related to the playability and performance testing, it shows that map are being generated by the generators are playable and performance that are analyzed using Big O notation show O (n) (linear).
