LIDAR systems have been regarded as novel technologies for efficiently acquiring 3-D geo-spatial information, resulting in broad applications in engineering and management fields. Registration of LIDAR point clouds of consecutive scans or different platforms is a prerequisite for fully exploiting advantages of afore-mentioned applications. In this study, the authors integrate point, line and pl...

When small cells are densely deployed in the fifth generation (5G) cellular networks, the base stations (BSs) switch-off strategy is an effective approach for saving energy consumption considering changes of traffic load. In general, the loss of coverage efficiency is an inevitable cost for cellular networks adopting BSs switch-off strategies. Based on the BSs switch-off strategy, an optimized ...

(Kiparsky 1971, 1973) draws attention to cases of historical change that suggest that at least some opaque phonological process interactions are difficult to learn. In his work on Stratal Optimality Theory (Stratal OT), he further claims that independent evidence about the stratal affiliation of a process is helpful in learning an opaque interaction (Kiparsky 2000). In this paper, we develop a ...

In this paper we consider some constraints on brane-world cosmologies. In the first part we analyze different behaviors for the expansion of our universe by imposing constraints on the speed of sound. In the second part, we study the nature of matter on the brane world by means of the well-known energy conditions. We find that the strong energy condition must be completely violated at late stag...

We test the theoretical prediction that profit sharing reduces worker separations and by doing so increases the incidence of training. Using individual level UK data, we confirm that profit sharing is a robust determinant of lower separation rates and of greater training incidence. Critically, we cannot confirm the predicted link between separations and training. Instead, the evidence supports ...

Recently, Dementhon 0 Davis [2] proposed a method for determining the pose of a 3-0 object with respect to a camera from 3-D to 2 0 point correspondences. The method consists of iteratively improving the pose computed with a weak perspective camera model to converge, at the limit, to a pose estimation computed with a perspective camera model. In this paper we show that the method of Dementhon €...

In this paper, I present a version of a sense-data approach to perception, which differs to a certain extent fromwell-knownversions like the one put forward by Jackson. I compare the sense-data view to the currently most popular alternative theories of perception, the so-called Theory of Appearing (a very specific form of disjunctivist approaches) on the one hand and reductive representationali...

The trend in most of the industrialised counties is in the direction of decreasing labour force participation of older workers. The steady withdrawal of workers from the workforce at a younger age suggests that retirement income is gradually increasing and/or that older workers are increasingly being forced out of the labour market. Regardless of whether early retirement can be traced to the la...

The prospects for large scale commercialisation of sea-bedmounted offshore windfarms are currently excellent, with the existing small-scale prototype windfarms currently being joined by the first large-scale parks in the shallow seas off the Danish, German, Swedish, Dutch, Belgian, British and Irish coasts. However other countries, including Japan, have much more limited regions of the shallow ...

The existing social network privacy protection method mostly aims at the individuals of the social network, which cannot protect effectively the sensitive relations in the social network. Therefore, this paper proposes a new personalized K_L model. This model requires each sensitive relation with the sensitive relational point have l at least, and also the point with the same requirement has k ...
