Some robotic tasks (grasping by a dextrous hand, planning the motion of an all-terrain vehicle, ..) need to study complex contact interactions between the robot and its environment. Classical geometrical models (representing the spatial properties of an object) dont't suit the study of such interactions. Because these interactions depend on physical properties such as mass, mass distribution, r...

To approximate the multivariate functions with spatial inhomogeneity, in this paper we proposed an ortho-ridgelet neural network (ORNN) model. By taking orthonormal ridgelet, which is a “true” ridgelet function different with the “classic” ridgelet, as the activation function of the hidden neurons, the network is characterized of more efficient representation of a set of functions with linear a...

In this dissertation, we focus on developing simultaneous localization and mapping (SLAM) algorithms with a robot-centric estimation framework primarily using monocular vision sensors. A primary contribution of this work is to use a robot-centric mapping framework concurrently with a world-centric localization method. We exploit the differential equation of motion of the normalized pixel coordi...

A great poem that touches the core heart of readers executing rustic forefathers’ lives and emotions is nothing but Gray’s Country Churchyard which uplands lawn with kindred spirit. Gray harnesses breezy calls enviously kiss us in destiny ‘’homely joys’’. The humble buried beds are not only twittering ears also they signification clarion call figure out solemn background rude forefathers who un...

Abstract A grass cutter is a machine that uses revolving blade or blades to cut lawn grass. Many designs have been made, each suited particular purpose and this robot used string trimmer as the cutting blade. This designed operate by rechargeable battery can be described an intelligent because micro-controller will receive information from sensors connected it in avoiding obstacle ensure neat p...

An integration of remanufacturing into an original equipment manufacturer’s (OEM) value chain can enhance circularity. In order to realize a transition towards circularity, it must be economically beneficial. This paper aims compare and evaluate several scenarios with varied retailer involvement, identify how electrical electronic (EEE) manufacturer perform profitably. To meet the aim this pape...

Transmission of the bacterium occurs primarily through bites from arthropods, including the dog tick (Dermacentor variabilis), the wood tick (D. andersoni), the lone star tick (Amblyomma americanum), and the deer fl y (Chrysops spp.). In addition, contact with infected animals, most commonly rabbits, wild rodents, and cats, is another common route of transmission to humans (1,6). Tularemia occu...

A penetrating injury by a foreign body is comparatively common in the oral and maxillofacial region. On the other hand, injury to the temporomandibular joint (TMJ) by a foreign object is very rare. The TMJ is an anatomically narrow space surrounded by hard bony processes. An unusual case of trauma with severe trismus caused by a foreign body that impaled the TMJ is reported. A 55-year-old man p...
