A new triaxial dynamometer was designed, constructed and tested to measure and locate the position of all forces and moments on tillage implements, up to a maximum force of 10 kN and a maximum moment of 10 kN 9 m. The design concept of the facility was based on four frames attached to each other by load cells and tillage tool were attached on the inner frame. Calibration of the system showed the reliable and precise performance of the dynamometer in tracking the forces and moments. Additionally, the designed setup operated desirably under field conditions. Draft measurement was compared to those predicted by ASABE Standard D497.7 and was found to be in standard range. By using the new facility, it would be possible to study the relationship between forces and moments at the varying practical cases and design of tines, toolbars and tillage equipments in regard to the soil type and available tractor power will be facilitated.

Due to its critical role in safety of passengers, air bag deployment has to be highly reliable. Existing crash sensing/detection for air bag deployment are based on single sensing device. Multi sensor decision fusion has the potential for increased reliability in decision making using measurements from multiple sensors. In this paper, multi sensor decision fusion algorithm for reliable frontal crash detection and airbag deployment in an automobile using multiple sensors deployed on-board. Decision level fusion of sensor measurement data from an accelerometer located on vehicle engine and a load-cell on the driver shoulder-belt is employed for airbag deployment decision. For state estimation from sensor data, Kalman Filters are developed and tuned for the specific sensors. Crash detection at individual sensor level is also made reliable using a Cumulative Sum Control Chart (CUSUM) based change detection logic from the estimated data. The estimation, detection and decision fusion blocks of the algorithm are implemented in MATLAB and integrated. The resulting crash detection algorithm is tested and validated using US National Highway Traffic Safety Administration (NHTSA) automobile crash data sets. The time taken in the worst case is well within the acceptable bounds of airbag deployment time (50 ms) even with unoptimised MATLAB implementation.

Field administration engineers require an assortment of load cells crossing the various reaches expected to align their clients' frameworks. They may require the grouping to lead an extensive variety of power estimations for a specific testing application. The test starts when the specialist needs to change the load cell that is associated with his instrument before, he can proceed. At the point when the new cell is associated with the instrument, the proper alignment factors should be introduced in the instrument.
Several studies have identified distortion-induced fatigue as the leading cause of cracks in steel bridges built prior to the mid-1980s (Lindberg and Schultz 2007, Roddis 2001). Experimental and computer simulations of 914-mm (36-in.)... more
Several studies have identified distortion-induced fatigue as the leading cause of cracks in steel bridges built prior to the mid-1980s (Lindberg and Schultz 2007, Roddis 2001). Experimental and computer simulations of 914-mm (36-in.) deep girder-cross frame subassemblies subjected to cyclic loading were carried out to study the effects of distortioninduced fatigue and to evaluate the effectiveness of various retrofit measures. Previous repair methods for distortion-induced fatigue damage have attempted to reduce the stress demand at the critical web-gap region by increasing the flexibility of the girder web in the out-of-plane direction or by restraining the lateral motion of the web by fixing the connection stiffener to the girder flange. A new approach was investigated in this study intended to reduce the stress demand in the web-gap region by re-distributing the out-of-plane force transferred through the girder-cross frame connection over a larger area of the girder web. A new r...

Large superconducting magnets will play a central role in the success of the International Thermonuclear Experimental Reactor (ITER) and for the future of fusion energy. Cable-in-conduit conductors (CICC) will be used for the ITER magnets. As a CICC is energized, electromagnetic forces accumulate across the conductor, pressing strands transversely against one side of the conduit. We have developed a device

Till date, wireless technology was a patchwork of incompatible system from a variety of vendors. The technology was slow, expensive and reserved for mobile situation or hostile environments where cabling was impractical or impossible. In recent years, Zigbee has becoming one of the most promising protocols for wireless networking. Consequently, interoperation with Zigbee-enabled home network devices such as wireless sensor and appliances is an essential functionality in gateway systems. With maturity of industry standards and the deployment of lightweight wireless networking hardware across a broad market section, wireless technology has come of age and Zigbee is a new player in the field. This paper gives an overview of Zigbee's technical attributes, applications, products and its future and its application network in detail.
