The navigational tasks of computing time to impact and controlling movements in speci1c range are addressed here. We show how time to impact can be obtained via the Mellin-based correlator, and we introduce the concept of fractional based correlators. The fractional Fourier=Mellin based correlators can be used in detecting or controlling speci1c range of movements. Also, both the conventional a...

User-Web interactions have emerged as an important area of research in the field of information science. In this study, we investigate the effects of users’ cognitive styles on their Web navigational styles and information processing strategies. We report results from the analyses of 594 minutes recorded Web search sessions of 18 participants engaged in 54 scenariobased search tasks. We use que...

Traditional AI methods for navigational planning use qualitative spatial representations and reasoning. Traditional robotics techniques for this task are based on numerical representations and reasoning. Recent work on robotics posits mechanisms for reactive control that directly map perceptions of the world to actions on it. This in turn has given rise to hybrid robot architectures that combin...

Many scientists are interested in the different mechanisms and strategies that animals use to navigate. This paper reviews a series of studies and models about the navigational strategies that animals can use to move from one place to another. Studies of long-distance navigation have mainly been focused on how animals are able to maintain a certain orientation across a distance of hundreds of k...

Because navigational guidance can localize the operative site 3-dimensionally during maxillofacial surgery and provide precision, reliability, and safety for surgeons, we report Le Fort I osteotomy under navigational guidance for posterior repositioning of the maxilla.

Homing pigeons (Columba livia f.d.) are well-known for their homing abilities, and their brains seem to be functionally adapted to homing as exemplified, e.g. by their larger hippocampi and olfactory bulbs. Their hippocampus size is influenced by navigational experience, and, as in other birds, functional specialisation of the left and right hemispheres ('lateralisation') occurs in homing pigeo...

In this paper, we argue that web applications are a particular kind of hypermedia applications and show how to model their navigational structure. We motivate our paper discussing the most important problems in the design of complex Web applications. We argue that if we need to design applications combining hypermedia navigation with complex transactional behaviors (as in E-commerce systems), w...

Underwater gliders are prevailing in oceanic observation nowadays for their flexible deployment and low cost. However, the limited onboard energy constrains application, hence motion pattern optimization analysis key to maximizing range of glider while maintaining acceptable navigation preciseness glider. In this work, a Multi-Objective Artificial Bee Colony (MOABC) algorithm is used solve cons...

In many application areas, the access pattern is navigational and a large fraction of the accesses are perfect match accesses/queries on one or more words in text strings in the objects. One example of such an application area is XML data stored in object database systems. Such systems will frequently store large amounts of data, and in order to provide the necessary computing power and data ba...

Conducting data mining on logs of web servers involves the determination of frequently occurring access sequences. We examine the problem of finding traversal patterns from web logs by considering the fact that irrelevant accesses to web documents may be interleaved within access patterns due to navigational purposes. We define a general type of pattern that takes into account this fact and als...
