The purpose of this research is to explore the feasibility of applying an electronic nose for the intelligent monitoring of injurious insects in a stored grain environment. In this study, we employed an electronic nose to sample rough rice that contained three degrees of red flour beetle (Tribolium castaneum Herbst) infestation for different durations-light degree (LD), middle degree (MD), and ...

Future planetary exploration missions will require rovers to perform difficult tasks in rough terrain, with limited human supervision. Knowledge of terrain physical characteristics would allow a rover to adapt its control and planning strategies to maximize its effectiveness. This paper describes recent and current work at MIT in the area of terrain estimation and sensing. A method for on-line ...

Rice drying with infrared radiation has been investigated during recent years and showed promising potential with improved quality and energy efficiency. However, due to limited penetration capability of infrared radiation, thin layer drying may be used in infrared dryer design. The objective of this study was to study the moisture removal characteristics of thin layer rough rice heated by infr...

Equilibrium moisture content (EMC)/equilibrium relative humidity (ERH) studies pertaining to rice and rice products were reviewed. Methods of determining rice and rice component EMC/ERH data varied, using procedures involving static and dynamic equilibration methods, as well as direct gravimetric methods and indirect ERH‐measurement methods. Methods for measuring rice and rice component moistur...

This paper investigates the joint target parameter (delay and Doppler) estimation performance of linear frequency modulation (LFM)-based radar networks in a Rice fading environment. The active radar networks are composed of multiple radar transmitters and multichannel receivers placed on moving platforms. First, the log-likelihood function of the received signal for a Rician target is derived, ...

This paper introduces a method for predicting the likely behaviors of continuous nonlinear systems in equilibrium in which the input values can vary. The method uses a parameterized equation model and a lower bound on the input joint density. to bound the likelihood that some behavior will occur, such as a state variable being inside a given numeric range. Using a bound on the density instead o...

Cereal Chem. 80(1):30–34 Flours and starches from rough rice dried using different treatment combinations of air temperature (T) and relative humidity (RH) were studied to better understand the effect of drying regime on rice functionality. Rough rice from cultivars Bengal and Cypress were dried to a moisture content of 12% by three drying regimes: low temperature (T 20°C, RH 50%), medium tempe...

Rice is harvested in the Mid-South at moisture contents (MCs) typically ranging from 13% to 22% (wet basis). Because these MCs are greater than those safe for long-term storage, rice is dried within a fairly short period after harvest to 12% to 13% MC before being placed in storage. Once dried, “processing” of rough rice into milled rice takes place throughout the year and consists of several o...

A field study was initiated to evaluate a 3and 5-day furrow-irrigation schedule in a rice-production system. Averaged across furrow-irrigation schedules, ‘XL723’ height was greater than ‘Cybonnet’ in July and August of the growing season; however, panicle number was greater for Cybonnet than XL723. Yield components (spikelets, total kernels, and total filled kernels/panicle) and rough-rice yiel...
