B Double-modulated terahertz differential time-domain spectroscopy (double-modulated THz-DTDS), is a technique that is based on dithering the sample under test. In this paper, we report a measurement technique based on mounting the sample on a ...

Nowadays, the every vehicle existed mostly still using the two wheel steering system to control the movement of the vehicle whether it is front wheel drive, rear wheel drive or all wheel drive. But due to the awareness of safety, four wheel steering vehicles are being used increasingly due to high performance and stability that they bring to the vehicles. In this report, the performance of four...

overall energy efficiency (oee) is an important indicator of energy consumption in tillage operations. tillage energy was studied objectivity to accurately measure the oee of mf399-4wd tractor. the tractor was equipped with different types of sensors to measure and calibrate the required data including: fuel consumption, actual forward speed, wheel speed and slippage, engine speed, draft and dr...

An hybrid control architecture with reactive, deliberative, and cognitive components appropriate to human-oriented mobile robots is presented. The paper presents globally our control architecture and describes some of its modules in detail: local mapbuilding module, reactive control module and wheel ́s velocity controller. Some discussion is made concerning trajectory planning and path-tracking ...

Following the luminescence system lexsyg research, which was designed for research, the luminescence reader lexsyg smart for the application of luminescence detection was developed by Freiberg Instruments. It is suited for routine measurements of luminescence (thermoluminescence, photoluminescence, photon-stimulated, optically stimulated and infrared stimulated luminescence) for a wide range of...

An Two wheel self supporting robot is design using IOC(Internet-on-a-chip) controller. The DC motor is controlled by PWM technique. In the existing system the robot were designed using tilt sensor, IR sensor, Attitude sensor and moving robot in a straight line. We propose a new design in two wheel self support robot using the principle of curvature technique, were a force that makes the robot t...

This paper presents the key steps involved in the design, calibration and error modelling of a low cost odometry system capable of achieving high accuracy dead-reckoning. A consistent error model for estimating position and orientation errors has been developed. Previous work on propagating odometry error covariance relies on incrementally updating the covariance matrix in small time steps. The...

Let G1 and G2 be two given graphs. The Ramsey number R(G1,G2) is the least integer r such that for every graph G on r vertices, either G contains a G1 or G contains a G2. A complete bipartite graph K1,n is called a star. The kipas ̂ Kn is the graph obtained from a path of order n by adding a new vertex and joining it to all the vertices of the path. Alternatively, a kipas is a wheel with one edg...

When humans interface with machines, the control interface is usually passive and its response contains little information pertinent to the state of the environment. Usually, information flows through the interface from human to machine but not so often in the reverse direction. This work proposes a control architecture in which bi-directional information transfer occurs across the control inte...

Fatigue at the wheel has been strongly related to car accidents. Traditionally, this phenomenon has been studied in laboratory conditions by means of performance testing. Here, we aimed to improve road safety assessing driver fatigue at the wheel in real scenarios. For this purpose, we have built BioTracker R ©: a flexible non invasive platform. A smartphone and a microcontroller unit are the c...
