Modal parameter analysis is a common method for structural characteristic analysis. To accurately identify the modal parameters that describe vibration characteristics of structure, chassis frame rice transplanter taken as research object. The least squares complex frequency domain method, admittance circle and peak picking are used to process measured signal. parameters, such natural frequency...

Highlights An integrated GPS/INS/VNS navigation system was developed to improve accuracy. adaptive federal Kalman filter with information distribution factors used fuse information. Detection of seedling row lines achieved based on subregional feature points clustering. A modified rice transplanter as an experimental platform for automatic navigation. Abstract . In this article, global position...

Irradiated raw ground beef had lower a*- and b*-values than nonirradiated ones regardless of garlic or onion treatment at 0 d. Irradiation increased TBARS values of control ground beef, but addition of 0.5% onion or 0.1% garlic+0.5% onion reduced oxidative changes during storage. Addition of garlic or onion greatly increased the amounts of sulfur compounds, but the increase was greater with gar...

Onion Routing is an infrastructure for private communication over a public network. It provides anonymous connections that are strongly resistant to both eavesdropping and tra c analysis. Onion routing's anonymous connections are bidirectional and near realtime, and can be used anywhere a socket connection can be used. Any identifying information must be in the data stream carried over an anony...

457 Onion (Allium cepa L.) is an important export oriented vegetable among the cultivated allium in India. It is also known as “queen of kitchen”. Productivity of onion is affected by many biotic and abiotic stresses. For commercial cultivation of onion, both thrips and foliar diseases play the key role in reducing the bulb yield and quality of produce. Among the various foliar diseases affecti...

To decrease the impact of uncertainty disturbance such as sideslip from field environment on path tracking control accuracy an unmanned rice transplanter, a method for autonomous transplanter based adaptive sliding mode variable structure was proposed. A radial basis function (RBF) neural network, which can precisely approximate arbitrary nonlinear function, used parameter auto-tuning on-line. ...

BACKGROUND Detection of specific IgE antibodies against food materials indicates allergic sensitization. Some very widely consumed foods materials such as garlic and onion have rarely been investigated for their allergenic potential. OBJECTIVES To assess the presence of garlic and onion specific IgE antibodies in patients investigated for food allergy. METHODS Radioallergosorbent test (RAST...

Intercropping could alleviate soil-borne diseases, however, few studies focused on the immunity of the host plant induced by the interspecific interactions. To test whether or not intercropping could enhance the disease resistance of host plant, we investigated the effect of companion cropping with potato onion on tomato Verticillium wilt caused by Verticillium dahliae (V. dahliae). To investig...

The inhibitory effect of onion extract on cassava leaf polyphenol oxidase was investigated. The polyphenol oxidase from cassava leaves was strongly inhibited by various anti-browning agents such as L-ascorbic acid and L-cysteine. The percentage of inhibition increased with the increased of anti-browning agents concentrations. The addition of heated onion extract exhibited a stronger inhibitory ...
