Abstract: A Matlab program based on the discrete el
ement method was developed to simulate the
seeds motion in a 3
-
D vibrated seeder bed. The mechanical interactions force between
seeds and also between seeds and the bed were modeled by linear springs, dash
-
pots
and friction sliders. The cubic expansion coe
fficient, H, was calculated to describe the
discrete distribution level of seeds. The simulation results show that, the seeds are
separated effectively while the bed vibrated with high frequency and small amplitude,
H increases with the increasing vibratio
n strength, kv, and decreases with the seeds
initial thickness, hs. The influences of friction coefficient and recovery coefficient on
H were analyzed. The ideal active state was obtained at hs&asyum;3.8 and kv=5.65.
The experimental results also show that

the seeds

pickup ratio is more than 98%.

Abstract:
Aiming at solving the problem of low accuracy existing in the nondestructive testing
system for eggshell, a new hybrid scheme of rough sets and s
upport vector machine for
classifier designing was proposed. First, redundant characteristic parameters were
reduced based on the rough sets theory. During reducing process, the characteristic
parameters were quantified by fuzzy C means clustering algorith
m, and the condition
attributes were reduced via heuristic search according to their own importance. And
then, the classifier was trained by support vector machine based on the reduction result.
During training process, the classifier model parameters were

optimized by cross
validation. The experiments show that the accordance rate of the proposed method can
reach 94.6%, which has great engineering application perspective.

Abstract: In computer
-
vision
-
based systems for detecting foreign fibers, an effici
ent
segmentation method is vital for improving the speed and precision of detection. An
image enhancement model was presented based on histogram analysis, an improved
Otsu's method was proposed for segmenting gray images of foreign fibers, and the
segmenta
tion results were analyzed in detail. The results indicate that all histograms of
gray images of foreign fibers are of single peak, and the contrast between object and
background can be remarkably enhanced by the enhancement model presented. The
Otsu's met
hod is effective for images of sheet foreign fibers, but does not work well for
images of wirelike or villiform fibers, as some background pixels with gray values
closed to the threshold are easily segmented as object pixels by mistake. But after the
image
s were enhanced, the satisfactory segmentation results were achieved. The
improved Otsu's method reduced the searching range for calculating optimal threshold
from 0
-
255 to 150
-
230. The calculating speed in this stage was improved more than
twice.

Abstract: The key technology of no
-
row corn harvester is how to make corn stems being fed
effectively. Through analyzing the structure of existing no
-
row corn harvesters, a new
improved project was advanced on the basis

of feed
-
in mechanism with finger rotor,
stem
-
rotor and ear
-
rotor were installed independently, and the ear
-
rotor was closed
with sweep auger. The stem
-
rods were straight and the ear
-
rods were bended, their
eccentricity orientations were opposite when they

were installed, but they turned in the
same direction. As the ear
-
rotor was moved backwards, the effectiveness of ears
delivery was improved, and interference between the stem
-
rods and the ear
-
rods was
avoided. Change of the stem
-
rods eccentricity mountin
g orientation strengthened their
ability to transport stems, and increased effectively the range of feeding stem, thereby
the adaptability of the harvester to different corn row was improved. By designing the
stem motion simulation algorithm, virtual test
of the stems motion was completed with
the Matlab software, and the movement law of the stems was discussed. Equation of
the ear
-
rod was established, these provided a theoretical basis for the development of
prototype.

Abstract: Taking the main factors of apple processing by microwave vacuum drying into account,
such as microwave power, vacuum level and initial moisture content, the predicted
second
-
order
regression model of the sensory quality of microwave vacuum dried
apple slices was obtained according to the experimental data by using orthogonal
rotatable central composite design, and effects of these variables and their interaction
on the product quali
ty were analyzed by response surface method. To acquire higher
quality of product, the ideal processing range of microwave power, vacuum level and
initial moisture content were determined as 10.6
-
12.7 W/g, 0.083
-
0.094 MPa and
0.6
-
0.9 respectively. The opti
mal drying condition was found at microwave power 11.7
W/g, vacuum level 0.089 MPa and initial moisture content 0.75, with the maximum
predicted sensory quality mark as 9.51, and the experimental validated mark as 9.42.
The results prove that the regressio
n model agrees well with the microwave vacuum
drying process.

Abstract: Combined with the requirement of vehicles damper, two type of dampers were
designe
d and manufactured by analyzing the two working pattern of MRF. The
comparison between simulation and the experiment result shows that the difference of
damp force is small in low speed and large in high speed. It is obvious that the
performance of the mix
ed model is more excellent than the flow model. It has higher
control rate and can reduce the jam of the damp hole in practice. It is certified that the
magnetorheological fluid damper (MRD) model and the design idea and methods are
correct and accord with

the requirement of engineering.

Abstract: Because of inertia and changing load, the angular velocity fluctuation of constant speed
motor (CSM) was generated in hybrid mechanism, and the precision of out put
trajectory was reduced. The control strategy which applies servo

motor tracking
velocity of CSM was put forward, for CSM was uncontrollable. The control platform
of hybrid machine was presented. The fuzzy controller was designed by means of the
control scheme, and the velocity fluctuation was compensated for accurate
i
mplementation given trajectory. The result of experiment indicates that the fuzzy
controller was feasible and effective.

Abstract: Particles of rice straw processed by sodium hydroxide can be used as binder in biomass
fuel. Th
e quadratic orthogonal rotation design with three factors was used to study the
effects of the mass fraction of NaOH, temperature, and reaction time of alkali treatment
on shear bond strength. Functional models of shear bond strength with three factors wer
e
established and analyzed by regress method in SPSS13.0 and response method in Matlab
7.1. The results show that the regression equation was effective, and the mathematical
model for the simulation was presented. The effect order of three factors was as f
ollows:
the processing temperature, the amount of consistency, reaction time. The optimum
conditions were 1.5% of consistency, 95
°
C of temperature and 17 h of reaction time.

Abstract: Focusing on the deficiencies in production line balancing of present methods, a new
method named production line's dynamic balancing method, which combined heuristic
method and visualization simulation

together, was proposed. In this method, a
double
-
objective model of line balancing was built up, which ensures the number of
workstations and the smoothness index are both minimum. Then an improved particle
swarm optimization algorithm was used to solve t
he problem. The production line
system is suitable to build its visualization simulation model by the simulation
software of Witness. At last, an instance of this method was discussed.

Abstract: A

scaling definition based on two times scale was provided for soil fragmentation
analysis. An experiment was conducted to uncover the relationships among soil
fragments fractal dimension and the falling weight, falling height, soil moisture content,
and sp
ecific fragmentation energy. The result shows that no relation exists among
fractal dimension, falling weight and falling height, but obvious correlation appears
among soil fractal dimension, moisture content and specific fragmentation energies. A
further
comparison of fractal dimensions shows that soil under impacting action has a
much lower value than that under natural actions.

Abstract: Aiming at the classification problem of the complex product voice of cust
omers with a
large number of catalogs and data volumes, a heuristic strategy was proposed to
resolve the coding designing problem by using output of a probability minimax
machine and sample interval attribute. An algorithm with less iterative step s of
opt
imization was taken as a "weak" algorithm while preserving its other characteristics
like large margin and geometric properties. The nonlinear mapping was applied for
"weak" algorithms' output (vector) to work in high dimensional spaces and improve the
per
formances. At last, the experiments with the propose d algorithm were described to
show that the approach was more effective than others by using forklift VOC.

Abstract: The hydraulic calculation of drip irrigation submain units plays a key
role in the system
design. The finite element method with virtual emitters can compute the head loss of
each submain and capillary. The ways to reduce computational errors were suggested
by selecting a certain amounts of elements in order to meet drip irri
gation design need.
Moreover, finite element method with virtual emitters can re duce computational work
and memory demands dramatically. The research method put forward in this study
provides a new way for hydraulic design of large drip irrigation system.

Abstract: The basic parameters of plant straw packaging container, such as Poiss on ratio, elastic

modulus and so on, were gained by means of static compression test. The mechanical
model was established from the force
-
deformation curve, and the packaging container
was also analyzed through finite element method (FEM) based upon parameters and
the mode
l above. Some parameters such as the stress distribution law, stiffness and
breaking strength under compression load were obtained and the easy
-
crackled
position was also determined. It is proved that the calculation results are in accord with
the experime
ntal results. The research is the foundation for study on crack damage of
tableware and provides evidence for the structure design and mould development.

Abstract: The dymamical behavior of MEMS devices is strongly affected by viscous fluid
damping effects from the surrounding. These damping effects have to be caref
ully
considered for the design and optimization. For predicting the hydrodynamic loading
of an electrostatical device in viscous fluids, it is necessary to build an
electrostatic
-
mechanical
-
fluidic coupled model, where the flows characteristics were
descri
bed by Navier
-
Stokes equations. Comprehensive analyses of the static/dynamic
closing behaviors of the microswitch in viscous fluids were performed. Compared with
published work of other researchers available in the literature, the numerical model
was valid
ated. After that, the static/dynamic closing voltages of the microswitch in the
air and deionized water were calculated. The transient behaviors of microswitch under
different action voltages were also simulated, including the squeeze
-
film damping
pressure

distribution as well. The results show that the difference between the static
and the dynamic pull
-
in voltage in the deionized water is smaller than that in air.

was maped to a high
-
dimensional feature space in which the data has been clustered
efficiently. The precision of four kinds of

experimental maize diseases recognition is
82.5%, and kernel K
-

Abstract: In order to solve the problem of small
seed's precision seeding, such as vegetable and
flower seeds, a new type of magnetic cylinder
-
seeder was developed according to
the magnetic seed
-
metering principle. By analyzing and comparing magnetic field
route and intensity of one row suction head in t
he case of two kinds of polarity
arrangements, the designed project was ascertained that four rows of magnetic
suction head were assembled in the cylinder inner and its pole was arranged
according to gap way. To improve the metering performance of this dev
ice, the
orthogonal experiment was conducted with test object of rapeseed coated with
magnetic powder, test factors of cylinder rotation rate and suction head's electric
current. Variance analysis of the experiment results indicates that the suction head's

electric current is the main factor and the optimization of two factors are the suction
head's electric current of 230 mA and the cylinder rotation rate of 15 r/min. Under
such working conditions, the single seed index is 93.6%, multi
-
seed index is 2.2%,
and the seed
-
metering efficiency could achieve 3600 rows per hour, so it proves that
this machine has higher sowing precision and better adaptability to small seeds.

Abstract: The oscillating hot air that generated

by a pulse combustor can be used to atomize
and dry liquid materials. It has many advantages, such as low operation cost, high
drying quality, and simple structure of the dryer. A small Helmholtz pulse combustor
was used in this research. An optical analy
zer was employed for measuring the mean
diameters of atomized droplets and droplets size distribution. The feed rate and
viscosity of liquid material, frequency of oscillating hot air are the main factors
affecting the atomizing properties. The experimenta
