Mobile IPv6 enables mobile node to roam transparently in any network. It shows good performance for macro mobility but it is not proper for supporting micro mobility because of large latency. Accordingly, IETF (Internet Engineering Task Force) mobileip WG(Working Group) suggests Fast Handover Protocol and HMIPv6(Hierarchical Mobile IPv6) for micro mobility management. However, HMIPv6 has some p...

The aim of this research is to design and implement line-tracking mobile robot. The robot must follow a line drawn on the floor with different color, avoids hitting moving object like another moving robot or walking people and achieves color sensing. The control system reacts by controlling each of the motors to keep the tracking sensor over the middle of the line. Proximity sensors used to avo...

While autonomous multirotor micro aerial vehicles (MAVs) are uniquely well suited for certain types of missions benefiting from stationary flight capabilities, their more widespread usage still faces many hurdles, due in particular to their limited range and the difficulty of fully automating the deployment and retrieval. In this paper we address these issues by solving the problem of the autom...

This paper discusses the design of micro-robot legs based on the skiing principle using an improved version of the inchworm motors for the SMART DUST program. Four inchworm motors are attached to each of the two parallel sides of a SMART DUST mote to serve as the ski legs and support legs for the dust mote. The ski legs push the micro-robot at 75° from the surface and are capable of moving a mi...

Micro Particle Image Velocimetry (μPIV) is a non-invasive flow field measurement technique, which is becoming the method of choice for the investigation of micro-flows. Measurements of flows which occur within the human body represent one of the most important applications of μPIV. A three-component two-dimensional scanning micro-Particle Image Velocimetry (μPIV) technique is presented in this ...

Intertidal mudflats play a critical role in estuarine exchange, connecting marine and continental supplies of nutrients and sediments. However, their complex morphodynamics, associated with a wide range of physical and biological processes, are still poorly understood and require further field investigation. In addition, mudflats are challenging areas for Structure-from-Motion (SfM) photogramme...

In this paper we address the problem of tracking motion in diverse video when the camera may also be in motion. Our implementation handles this diversity by integrating a variety of approaches and selecting the appropriate approach or approaches for the input material using an intelligent algorithm on a frame‐by‐ frame basis. Accuracy is over 75% for some inputs and can handle up to 10 frames p...

The present study is devoted to an approximate modeling for numerical simulation of flows past oscillating airfoils. In this study, it is shown that the harmonic oscillating objects can be studied by simple numerical codes that are not able to solve moving grids. Instead of using moving grid for the simulation of flowfield around an oscillating airfoil, this unsteady flow is solved on a fixed g...

Extracting moving objects from a video sequence is the first step of many video processing applications, including traffic monitoring and security surveillance. If the camera is fixed in the scene, we can detect moving objects by background subtraction, and many methods have been proposed for generating background images in varying illumination conditions[4, 13]. For images taken by a pan-tilt ...

Background: Uranium poses both chemical and radiological hazard to the living system. Drinking water from river is one of the major sources of uranium intake. Dissolution of minerals, washout from rain water, rock-water interaction, agricultural run off, and industrial disposals are some of the sources of uranium in river water system. Present study was aimed to determine the uranium in the wat...
