We used Vehicular ad hoc networks to improve traffic safety and efficiency, which communicates with each other using sensed available spare spectra. The medium access control layer configuration determines a common set of channels to facilitate communication among participating nodes.…

The research aims at weakness and diversity characteristics of electromagnetic ultrasonic signals and demand of portable devices based on electromagnetic acoustic transducer and designed an electromagnetic ultrasonic data acquisition system. Data exchange between computer and acquisition circuits was realized through…

Loading system is the most important system of multi-functional engineering machinery. This paper analyzed the mathematical models of electro-hydraulic servo valve and variable fuel tanks. By using the PID controller to adjust the parameters, mainly from step loading model and…

Soil volumetric water content measurement always use Time Domain Reflectometry, which exploits the difference in dielectric constant values between the solid phase, air phase and liquid phase. We tried to use the empirical data and model to fit the Time…

The shearing strength-shearing displacement model of deep-sea soft sediments is quite important to predict the traction and slip ratio of nodule collector. According to the physical mechanics characters of the deep-sea soft sediments, the 321 sodium molybdate swell soil samples…

Regeneration potential of pseudobulb segments of Malaxis acuminata, procured from in vitro grown cultures, was analysed in Mitra et al., 1976 medium and its combinations with growth adjuncts. Juvenility of the tissues and chemical stimulus emerged as important factors in…

(Abstract selected from presentation in National Conference on Biodiversity of Medicinal and Aromatic Plants: Collection, Characterization and Utilization, held at Anand, India during November 24-25, 2010)  Systematic mapping of species occurrence in a given area provides distributional pattern related to ecological…
