In the past decade, profits obtained by banks in Indonesia have generally tended to increase, except during pandemic. However, number of banking business actors has continued decline, indicating that structure is becoming more concentrated and potentially leading an oligopoly. Therefore, purpose this study determine whether increasingly market or weak competition a significant impact on growing...

Bidding in simultaneous auctions is challenging because an agent’s value for a good in one auction may depend on the outcome of other auctions; that is, bidders face an exposure problem. Given the gap in our understanding (e.g., lack of game-theoretic solutions) of general simultaneous auction games, previous works have tackled the problem of how to bid in these games with heuristic strategies ...

A wide range of existing power technologies can make use of the solar energy reaching Earth. Basically, all those ways can be divided into two basic categories: transformed for use elsewhere or utilized directly – direct – and involving more than one transformation to reach a usable form – indirect. The Solar Chimney Power Plant (SCPP) is part of the solar thermal group of indirect solar conver...

the interactive effects of adjacent buildings on their seismic performance are not frequently considered in seismic design. the adjacent buildings, however, are interrelated through the soil during seismic ground motions. the seismic energy is redistributed in the neighboring buildings through multiple structure-soil-structure interactions (sssi). for example, in an area congested with many nea...

Previous studies have shown that the crosswind reduces output power of a SCPP (solar chimney plant) with deflection plume at exit and separation wind flow there downstream. The present numerical investigation was focused on effect stack configuration performance SCPP. In this paper, prototype in Manzanares simulated, where Boussinesq approximation used for solving continuity, Navier–Stokes ener...
