There are various methods in the field of moving-object tracking in the video images that each of them implies on the specific features of object. Among tracking methods based on features, algorithms based on color are able to provide a precise description of the object and track the object with high speed. One of the efficient methods in the field of object tracking based on color information ...

potassium bromide (kbr), an old antiepileptic agent, is illegally used in pharmaceutical or food industries to improve the product appearance. kbr has been proven to influence several pathways which are important in memory formation. therefore, the present study aimed to evaluate the effect of kbr on spatial working memory using object recognition task (ort). rats received a single dose of kbr ...

In this paper a conceptually simple structural object model focusing on object types, attributes and ISA relationships is introduced. The model is derived mainly from an extended Entity-Relationship approach, but concepts from other semantic and object-oriented models have innuenced its features. It is shown how high-level conceptual data models can be mapped to this model, and to what extent t...

In underwater, object information is received by sonobuoy. The sonobuoy generates object range and bearing measurements. Extended Kalman filter is utilized to process the noise corrupted measurements for generation of object motion parameters (OMP). OMP is communicated to the aircraft through a link namely ultra-high frequency link for further processing. Results obtained in the simulation are ...

An adaptive object recognition scheme for image sequences of many object scenes is described. The scheme is applied for t r d c object recognition under ego-motion. The recursive estimation of object states is performed by an extended Kalman Filter with modified error estimation, which is a neural network learning process. This new feature allows to separate the judgment needed for selection of...

For irregular extended object and group target tracking (IEOT and IGTT), using a random matrix to simplify the extension as an ellipsoid, although efficient, may not be accurate without losing useful information in shape and orientation. In view of this, we consider modeling an irregular extended object or target group as a combination of multiple regular sub-objects. Each sub-object can be des...

In our efforts to develop an object-oriented visual programming language, the dataflow model of computation is extended from its traditional functional model to an object-oriented model. It is argued that the concept of subroutine in the object-oriented model requires two different types of calling (activation) mechanisms, the synchronous call and the asynchronous call. Asynchronous subroutine ...

Existing object databases define the behaviour of an object in terms of methods declared by types. Usually, the type of an object is fixed and therefore changes to its behaviour involves schema evolution. Consequently, dynamic configurations of object behaviour are generally not supported. We define the notion of role-based object behaviour and show how we integrated it into an existing object ...

Two experiments examined 3- and 4-year-old children's ability to map novel adjectives to object properties. Sixty-four children were introduced to a target (e.g., a bumpy object), and asked to choose between (1) a matching test object (e.g., a different bumpy object), and (2) a contrasting test object (e.g., a smooth object). Four-year-olds successfully extended novel adjectives from the target...
