dark and deep, but the shallow, sunlit edges are where most of the cichlids live. Brown or green Eretmodus algae scrapers, covered with blue spots, thrive among the breaking waves; the turbulent water pushes their rounded backs onto the rock surfaces instead of pulling them off. These fish nip algae off the rocks with their chisel-like teeth. Their neighbors the Tanganicodus insect pickers also...

The younger Laetolil hominids provide evidence of a unique anterior cutting complex with a chisel-like action occurring between the lingual-distal C face and a transverse ridge on the P, perpendicular to it, extending between the subequal cusps. An earlier adaptation to more efficient grinding may have resulted in reduced canine projection and the development of the lingual P3 cusp, raising the...

VoiceXML (Voice Extended Markup Language) has become a major force in interactive voice services. However current approaches to creating VoiceXML services are rather low-level. Graphical representations of VoiceXML are close to the textual form of the language, and do not give a high-level description of a service. CRESS (Chisel Representation Employing Systematic Specification) can be used to ...

Grid services and web services have similarities but also significant differences. Although conceived for web services, it is seen how BPEL (Business Process Execution Logic) can be used to orchestrate a collection of grid services. It is explained how CRESS (Chisel Representation Employing Systematic Specification) has been extended to describe grid service composition. The CRESS descriptions ...

In the modern motorcar production, more than 300 deep-drawn sheet metal parts are joined together by more than 3,000 spot welds on each car body. To check the spot welds within the framework of the quality assurance, different nondestructive test methods are available in addition to the destructive methods (tear down test, metallographic inspection): the chipping test and the ultrasonic test, w...

Experiments were performed with the NASA Robonaut to determine if manifold learning could discern successful and unsuccessful teleoperation trials in an unsupervised manner. Repeated teleoperation of drill-mating and chisel-pickup tasks were performed by a skilled teleoperator. Spatio-temporal Isomap (STI) was used to embed data from the robot’s sensory-motor state-space (SMSS) to uncover under...

The Smart Alignment Tool for Knee MosaicPlasty Surgery is a device that aids in aligning the MosaicPlasty harvesting chisel with the cartilage surface of the knee. In the standard arthroscopic procedure, the angle at which the graft is harvested and inserted is determined visually by the surgeon through a single endoscopic view. The ability of the surgeon to obtain and place these grafts in an ...

The use of laminate composites in structures is under a considerable increase. The advantages of their use are related with a considerable weight reduction and consequent improvement of dynamic characteristics, in the case of aeronautics, automobile, railway and naval industries. Drilling is a widely used technique as it is always needed to assemble components in more complex structures. Drilli...
