Developed an integrated intellectual computerized system of ecological-economic monitoring, modeling, and managing the life cycle of the products of technogenic enterprises of transport engineering, which is presented in the form of a 3-equation structure, functioning in conditions of instability. The proposed paradigm system life cycle management applicable to any other control system of large...

this paper considers the problem of stable limit cycles generating in a class of uncertain nonlinear systems which leads to stable oscillations in the system’s output.this is a wanted behavior in many practical engineering problems. for this purpose, first the equation of the desirable limit cycle is achieved according to shape, amplitude and frequency of the required output oscillations. then,...

Saat ini UMKM (Usaha Mikro Kecil dan Menengah) sangat berperan penting dalam peningkatan perekonomian negara berkembang seperti Indonesia. Pengusaha-pengusaha telah terbukti memiliki ketangguhan kemampuan menghadapi krisis ekonomi. Upaya meningkatkan atau mengoptimalisasikan pemasaran kemasan, promosi, kondisi produk, bahan legalitas perijinan layak tidaknya makanan itu beredar di pasaran harus...

So far, extremely efficient metabolic pathways for nitrogen removal exclusively by autotrophic organisms are well established in scientific literature but not in practice. This paper presents results from the successful implementation of rejection water deammonification in a full-scale single sludge system at the WWTP Strass, Austria. Anaerobic ammonia oxidising biomass has been accumulated dur...

A three-dimensional non-linear finite-element model (FEM) was constructed using a commercial software (ATENA-Studio) to investigate the transverse load distribution behavior of adjacent precast prestressed concrete box-girder bridges. An innovative connection between box girders used, where post-tensioning applied at top flanges only eliminating need for intermediate diaphragms. The FEM validat...
