Teams of humans and robots working together can provide effective solutions to problems. In such applications, effective human-robot teaming relies on being able to communicate information about the current perception or understanding of the environment. In this paper, human-robot teaming on navigational tasks is discussed. The role of the human user will be to specify the goal point(s) for the...

How do honeybees use visual odometry and goal-defining landmarks to guide food search? In one experiment, bees were trained to forage in an optic-flow-rich tunnel with a landmark positioned directly above the feeder. Subsequent food-search tests indicated that bees searched much more accurately when both odometric and landmark cues were available than when only odometry was available. When the ...

the aim of this study was to compare the lateral window and osteotome techniques for sinus lifting using histological and histomorphometric methods.in this clinical trial 10 patients (a total number of 14 sinus areas) who needed implant treatment in the atrophic posterior maxilla were enrolled. in all the cases the residual bone height between the sinus floor and the alveolar crest was less tha...

background: the aim of this study was to determine the correlation between ultrastructural studies for pinopodes expression after ovarian hyperstimulation and progesterone injection in mice. materials and methods: adult nmri mice were superovulated using human menopasual gonadotropic (hmg) and human chorionic gonadotropic (hcg) hormones; after that, daily injection of progesterone (1 mg/mouse) ...

This paper investigates the function and formation of spatial language involving landmarks. We argue for two points. First, landmarks have an important function in spatial language. Agents that can use different landmarks and express their choice perform better than agents who cannot. Second, the use of landmarks has a positive effect on evolving systems of spatial relations. Agents that have t...

We propose the novel approach of dynamic affine-invariant shape-appearance model (Aff-SAM) and employ it for handshape classification and sign recognition in sign language (SL) videos. AffSAM offers a compact and descriptive representation of hand configurations as well as regularized model-fitting, assisting hand tracking and extracting handshape features. We construct SA images representing t...

In this paper, facial expressions of the three Turkish presidential candidates Demirtas, Erdogan and Ihsanoglu (in alphabetical order) are analyzed during the publicity speeches featured at TRT (Turkish Radio and Television) on 03.08.2014. FaceReader is used for the analysis where 3D modeling of the face is achieved using the active appearance models (AAM). Over 500 landmark points are tracked ...

We present an algorithm that efficiently tracks a predefined set of landmark points in a time sequence of images. The algorithm iteratively optimizes the correspondences between the point measurements in the images, while allowing for spurious and missing point measurements. This trajectory based approach hypothesizes missing points by interpolation. Spurious measurements are either left out be...

Are courts effective monitors of corporate decisions? In a controversial landmark case, the Delaware Supreme Court held directors personally liable for breaching their fiduciary duties, signaling a sharp increase in Delaware‘s scrutiny over corporate decisions. In our event study, low-growth Delaware firms outperformed matched nonDelaware firms by 1% in the three day event window. In contrast, ...
