In the following concepts regarding the in agricultral machinery, which of the following statements are correct? (Need to include all correct options):
I. In silico design of agricultural machinery implies modeling the effect of a change in the machine settings on the crop in the machine. This requires a material model that accurately describes the behavior of the biological material inside the machines. While such material models are well-established for engineering materials, such as steel and polymers, accurate material models for fibrous biological materials are still lacking. The absence of such accurate material models is considered the main reason why such simulation tools are still hardly used in agricultural machinery design.
II. Minimizing the discharge distance from the forager spout to the trailer, even with large headers, is crucial for efficient harvesting and preventing crop loss.
III. Blanching enhances the sensory properties and nutritional value of fruits and vegetables by activating enzymes that preserve color, aroma, and texture while increasing soluble nutrient content.
IV. Minimizing the operational width, depth, and speed of implements is crucial for maximizing power demand, fuel consumption, and field capacity, thereby enhancing the economic viability of UAGVs.
V. The FAO 56 method for estimating crop evapotranspiration disregards meteorological data and relies solely on the complex interplay between net radiation, soil heat flux, latent heat flux, and sensible heat flux.

In the following concepts regarding the in agricultral machinery, which of the following statements are incorrect? (Need to include all incorrect options):
1. Dehydration involves the simultaneous application of heat and removal of moisture from foods. Thermal drying is one of the most widely used methods of drying foods. In this process, heat is mainly used to remove water from the fruits and vegetables. The mechanisms of moisture transfer depend mainly on the types or physicochemical state of food materials and the drying process. Fruits and vegetable materials can be classified as homogeneous gels, porous materials with interconnecting pores or capillaries, and materials having an outer skin that is the main barrier to moisture ﬂow.
2. Vegetable seed size and plant architecture are inversely proportional to the complexity of mechanization systems, meaning simpler plants require more complex machinery.
3. Minimizing the operational width, depth, and speed of implements is crucial for maximizing power demand, fuel consumption, and field capacity, thereby enhancing the economic viability of UAGVs.
4. Solar drying is identical to sun drying, relying solely on direct sunlight without any structural enhancements to improve drying rates or lower final moisture content.
5. Roller conditioners minimize forage digestibility and protein value by selectively crushing leaves while preserving the stalks, achieved by regulating roller approximation and pressure.

D. only 5
E. 1

J. None of the above
Answer: H
In the following concepts regarding the in agricultral machinery, which of the following statements are incorrect? (Need to include all incorrect options):
I. The operational width, depth, and speed of operation of an implement are some of the major factors that determine the power demand (kW), fuel consumption (Lh−1 ), and the field capacity (hah−1 ) of agricultural machinery. These parameters (e.g., power demand, fuel consumption, and field capacity) which have a significant impact on the economics of crops, have to be considered in the techno-economic modeling phase of UAGVs.
II. Real-time control in surface irrigation eliminates the need for temporal variability considerations by separating measurement, optimization, and control into distinct, sequential processes.
III. Estimating crop evapotranspiration using methods of FAO 56 with meteorological instrumentation has played a key role in irrigation scheduling. The method incorporates the use of meteorological instrumentation to determine evapotranspiration levels of a crop canopy and uses the energy balance equation as its basis for ET calculations, i.e., $R_n - G- \lambdaET-H = 0$, where $R_n$ is net radiation, $G$ is soil heat ﬂux, $\lambda ET$ is latent heat ﬂux, and $H$ is sensible heat ﬂux (all units are $W m^{-2}$ ).
IV. Vegetable seed size and plant architecture are inversely proportional to the complexity of mechanization systems, meaning simpler plants require more complex machinery.
V. Controlled Traffic Farming (CTF) also facilitates greater precision in the relationship between crop and machine. RTK GPS autosteer systems have been shown to achieve precision in the order of ±25 mm 68% of the time, but this precision can be substantially degraded by a number of factors, including the transverse movement or "yaw" allowed by tractor tires. Transverse movement of implements relative to tractors can be even greater. Controlled traffic does not eliminate these effects, but they are reduced, and their effects largely negated by the use of consistent field patterns.

'Automobile exhaust pollution' has attracted worldwide attention. In an automobile internal combustion engine, gasoline is vaporized and mixed with air in a certain proportion before entering the cylinder, where it is ignited by an electric spark. Combustion causes the temperature in the cylinder to rise rapidly, the gas volume to expand rapidly, and pressure to push the piston. Harmful gases that pollute the atmosphere are discharged through the exhaust gas during combustion. To simplify the discussion, octane (C8H18) is used to represent the composition of gasoline, and it is assumed that $$O_{2}$$ accounts for 1/5 of the volume in the air. Assume that the volume ratio of octane gas to air (under the same conditions) is $$\alpha^{'}$$)______.

If the forward breakdown is at 300 V then when this voltage is reached the thyristor switches on and the voltage across it drops to 1 or 2 V. If the thyristor is in series with a resistance of, say, 20 Ω, then before breakdown there is a very high resistance in series with the 20 Ω and so virtually all the 300 V is across the thyristor and there is negligible current. When forward breakdown occurs, the voltage across the thyristor drops to, say, 2 V, hence the current rises to ___ A.
