Gabion-boxes, made with steel wire mesh and filled with stones of appropriated size, are normally stacked up one into another to form a retaining wall. Given their reduced costs and the easy availability of their constituting materials, gabion-box walls have been extensively used in developing countries (such as Nepal) also to realize simple one-storey residential buildings. In recent years, ma...

Described is a simulation model of cruising for garage parking, intended both for the calibration and evaluation of real-time parking recommendation methods, and as a base for predictive guidance to available parking. The model combines the event-based and agent-based simulation approaches to represent the parking garage and the driver behavior. It is validated by simulating a real-world parkin...

Potential problems could arise when drivers leave their parking stalls and merge into the main traffic stream. These problems could partly be attributed to finding acceptable gaps to merge into with safety and without causing undue difficulties to following vehicles. Observations from a variety of sites show different distributions of gap acceptance depending mainly upon the design and layout o...

The purpose of this paper is to investigate the fire performance in a multi-storey cross-laminated timber (CLT) structure by computational fluid dynamics (CFD) technique using Fire Dynamics Simulator (FDS v.6.7). study investigates temperature, heat release rate (HRR), and gas concentration (O2, CO2). importance research ensure that buildings adequate for occupant safety property protection. Mo...

Nowadays, in order to increase construction of tall structures, the importance choosing optimum systems, with a huge energy absorption capacity against wind and earthquake loads, has been widely considered. Since four decades ago, steel shear walls had used as stiff high performance lateral system. This study is about effect concrete filled tubes (CFT) columns vertical boundary elements wall on...

In this paper, we make a modification to the LS conjugate gradient method and propose a descent LS method. The method can generates sufficient descent direction for the objective function. We prove that the method is globally convergent with an Armijo-type line search. Moreover, under mild conditions, we show that the method is globally convergent if the Armijo line search or the Wolfe line sea...

The paper presents a study of a pilot plant treating light greywater for seven flats. The pilot plant combines biological treatment (RBC) with physicochemical treatment (sand filtration and disinfection). The pilot plant produced effluent of excellent quality, meeting the urban reuse quality regulations, and was very efficient in TSS turbidity and BOD removal: 82%, 98% and 96%, respectively. CO...

Maneuvers of a nonholonomic vehicle in a structured dynamic environment are considered. The paper focuses on motion generation and control methods to autonomously perform lane following/changing and parallel parking maneuvers. Lane following/changing involves the tracking of a nominal trajectory in the traac lane, and the generation and tracking of local lane-changing trajectories, for instance...
