Abstract We evaluate the impact of a price floor for alcohol introduced in Scotland 2018, using difference-in-differences strategy with England as control group. show that policy led to largest reductions units purchased among heaviest drinkers—the group who, at margin, are likely create externalities from drinking. The is well targeted heavy drinkers because they buy much greater fraction thei...

Several people working on the 2nd floor of an office building complained about disturbing floor vibrations. The building consists of five floors. In the contrary to the other floors, the 2nd floor slab has no floor-to-ceiling secondary walls neither beneath nor on top of the slab. The modal parameters of four floors were identified using ambient vibration testing (AVT)-technology and a 5-kg-med...

The outrigger arm system and belt truss with braced core in the center of the structure surrounded by belts truss, is an efficient and reliable system for high-rise buildings against severe lateral forces such as earthquake and wind. The purpose of this research is investigating the outrigger arm system and belt truss with the braced core under lateral loads. Another purpose of this research is...

E-commerce development is described in literature with reference to divergent points of views having many insufficiencies. In order to palliate these limits, this paper proposes a new construct, namely floors, corresponding to growing development levels. This construct permits e-commerce development influencing factors analysis. This paper proposes a model specifying factors influencing e-comme...

Methods to automatically derive landforms have typically focused on pixel-based, bottom-up approaches and most commonly on the derivation of topographic eminences. In this paper we describe an object-based, top-down algorithm to identify valley floors. The algorithm is based on a region growing approach, seeded by thalwegs with pixels added to the region according to a threshold gradient value....

C urrently, in relation to the problem of erecting buildings and structures using method lifting slabs floors, there is a need evaluate effectiveness organizational technical solutions process construction assembly works. This publication reviews installation works by floors with an analysis all advantages this over others. It also factors that affect effective use method. Basing on slab floor ...

This paper presents an optimal control strategy for elevator group in large buildings. An elevator group controller allocates different elevators to up and down hall calls that coming from different floors. The control strategy is a precondition to minimize mainly the average waiting time of hall calls. In this paper, two genetic algorithms are developed to treat efficiently the elevator group ...

We specifv and estimate an equilibrium job search model with pro” ductivitv differences across labor market segments. The model allows for two types of unemployment: frictional unemployment due to search frictions and structural unemployment due to wage floors. Wage floors exist because of high unemplovment benefits or binding minimum wages. The . productivitv distribution is estimated semi-non...

Fig. 1 shows that our system can easily model the failure case described by Müller et al. [MZWvG07] (left), where a global tiling cannot be found because different floors have different numbers of windows. Our automatic facade split, on the other hand, will put such floors in distinct clusters, and as a result they can be split into columns separately (middle). Nevertheless, all windows can be ...
