Rework adversely impacts the performance of building projects. In this study, data were analyzed from 788 construction incidents in 40 Spanish building projects to determine the influence of project and managerial characteristics on rework costs. Finally, regression analysis was used to understand the relationship between the contributing factors, and to determine a model for rework prediction....

This study investigated location-, movement-, and directional-selectivity of action potential discharges of hippocampal neurons in awake rats subjected to passive displacements in order to estimate vestibular contributions to this activity. Water-deprived rats were habituated to being restrained in a sling mounted on a moving robot. The extracellular activity of single complex-spike cells in ar...

The purpose of this paper is to analyse the e-voting systems implementation experience in Europe (and the world) and the necessity and possibility to implement the effective Out of Country Voting (OCV) for Moldova. This paper is aimed also to start a discussion on different aspects of information system “Elections” to be built in Moldova.

It is almost a statistical truism that the number of cells on each square of a haemocytometer is distributed in a Poisson series, but in fact it is easy to show that the distribution departs considerably from the theoretical expectation. The reason, perhaps, is that the experimental work confirming this theory was done on the old well type of haemocytometer, whereas the Burker counting chamber ...

In an electrical energy storage and delivery system, a parallel connection of battery modules can be used to increase the storage capability and power delivery demands. Parallel connection of batteries requires a robust battery management system as batteries may have different operating parameters such as state-of-charge (SoC), open-circuit voltage (OCV), internal resistance or battery chemistr...

Within a framework of reasoning with respect to clausal definitions of atoms, four forms of judgement are distinguished: Direct and indirect assertion, and direct and indirect denial. Whereas direct assertion and direct denial are established by directly applying a definitional clause (“definitional closure”), indirect assertion and indirect denial result from showing that all possible premisse...

Quadrotor is a type of rotor craft that consists of four rotors and two pairs of counter-rotating, fixed-pitch blades located at the four corners of the body. The flight control parameters optimization is one of the key issues for quadrotor. Estimation of distribution algorithm is a new kind of evolutionary algorithm developed rapidly recently. However, low convergence speed and local optimum o...
