Most importantly the rover process the sensor data to produce an estimate of its position while concurrently building a map of the environment.
Adding the implicit angle information, the original data is distance and direction information, which can be transformed to points in the Cartesian coordinates signifying sampling point’s information for the 2D.
Detect obstacles using laser range finder to get a range of data, which includes 361 distance data that correspond to the distance between the target and the center sensor.
The reduction of a measurement error can reduce all relevant estimate errors in the state estimation process; the system only provides a small amount of information [4] in state estimation for the correlation between the rover and characteristic signs.
The proposed method in article has been initially verified through simulation, but to achieve the accomplishment of the autonomous navigation needs much more further research on the data association of environmental apperceived information and trajectory planning problems of complex terrain in outdoor complex environment.

Eurobalise are categorized into two types namely, fixed data and variable data Eurobalise.
The data inside the fixed data Eurobalise cannot be modified while for the variable data Eurobalise, it is compatible to other train control equipment to transmit variable data to the train based on the condition.

Review of Pc-Sw Data for Network Model Validation O.
Drainage capillary pressure experimental data.
All the data possess different shapes of Pc-Sw including the data obtained from the same sandstones.
Though the data were normalized with the Leverret J-function, yet the data still appear scattered.

Moreover, the experimental equilibrium data was analyzed using the linearized form of Langmuir, and the Langmuir isotherm was found to provide the best theoretical correlation of the experimental data for the adsorption of Cu(II).
However, an increased trend in the magnitude of values on increasing the temperature showed a reduction in terms of the degree of spontaneity in all the three test temperatures.
R2 for the second order kinetic model was 0.9961, and was close to 1.0; the theoretical values of qe calculated from the linear form of the Pseudo-second order kinetic model was 125.5mg/g, and agreed well with the experimental data (121mg/g).
Kinetic studies performed indicated kinetics data tended to fit well in second order kinetics, confirming the chemisorption of Cu(II) onto CMC-S.

MATLAB software using Monte Carlo simulation to draw random data samples of built area, construction quality, probability of failure and occupancy level is used for the computational analysis.
The analytical approach is the most widely used because they can be applied to diverse types of structures and also in areas where building damage data are not sufficient [14].
Methodology In each of the five administrative divisions of Lagos state as displayed in Fig. 1, concrete compressive strength data for different structural members with design value of 25 N/mm2 for different buildings is obtained and analyzed to ascertain its compliance with standards for concrete construction.
Results and Discussion Table 2 shows data obtained from the study area.

The maximum torque at 2000 rpm of B100 is almost the same with that of B0, and the maximum power at 3400 rpm has a reduction of 4.5% than that of B0.
To show the data clearly, B0, B10, B20 and B30 are shown in Fig.
Under the whole range of speed, all BSECs of the blends and B100 are lower than that of B0; and with increase of biodiesel ratio, the degree of reduction becomes larger.
It can be seen that HC emission of all fuels is low under the whole speed range, and with increase of engine speed, HC emission of all fuels has some reduction.
Contrasted experiments of external characteristics indicate that, with increase of biodiesel ratio, the maximum torque is almost the same, and the maximum power has a little reduction, BSEC decreases, smoke and HC emission both decrease, but NOx emission and CO emission both increases.

Mechanical properties of grades in solution annealed condition Grade YS(N/mm2) UTS(N/mm2) %E 904L Specification 260 min 530 to 730 35% min Typical values 280 600 50% 2205 Specification 450 min 650 to 880 25% min Typical values 500 760 44% 317LM Specification 240 min 550 min 35% min Typical values 330 630 55% In order to study the effect of hot rolling reduction on mechanical properties, testing was carried out in sizes ranging from 7.0mm – 150.0mm rolled from 250 X 250mm square continuously cast blooms.
The test samples in solution annealed condition prepared as per ASTM A370 do not show any difference with respect to the reduction ratio.
The cold work hardening properties were studied by drawing wire rods in annealed condition and plotting the graph of tensile strength v/s percentage reduction.
This study revealed that the work hardening characteristics up to 30% reduction was similar in both grades 2205 ( Fig. 10) and 904L (Fig. 11) ; however, grade 2205 showed a higher pick up of yield strength in the initial reduction.

The application of elements for the active or semi-active vibration reduction managed by suspension control algorithms allows to control their dynamic characteristics.
Powering semi-active components requires power at signal level, while the active vibration reduction elements are supplied by an external high-power source.
In the work, the two-mode control has been made as independent per each suspension column equipped with semi-active vibration reduction elements.
Modes of kinematic inputs Analysis of data and conclusions The selection of the control method of the mechatronic suspension system of the presented vehicle has been driven by simplicity and operation efficiency.
This is why, for the sake of power economy, it is advised to apply combined structures, namely the hybrid vibration reduction systems.

The improved removal Cr(VI) at low pH was due to electrostatic attraction between negative charged Cr2O72 and the protonated CSAX chains and the direct reduction of Cr(VI) to Cr(III) in the solution.
The increased % M6 can be explained by the direct reduction of Cr(VI) to Cr(III) in solution, because chromium (Cr2O72-) became the main species in solution at pH 2.
The equation of reduction is as below: Cr2O72- + 14H+ + 6e- 2 Cr3+ + 7H2O After pH > 2.0 Cr(VI) existed as Cr2O72- and CrO42-coexistence in solution.
The aims are to make CSAX diffuse completely, between Cr2O72- and CSAX chains contact enough, resulting in the oxidation-reduction reaction absolutely.
From experimental phenomena, there were not flocs formed, which was in agreement with the data reported earlier [2].

Reduction of rate of change of forces acting on the platform and the effective damping of vibrations contributes to improve the working conditions of the crew which indirectly translates into higher efficiency of firing [2].
The disadvantages of this component are reduction of space in the vehicle and reduction of vehicle resistance against anti-tank mines.
Researches have showed reduction of vertical acceleration amplitude and increase of ride comfort, in relation to the model of 2S1 passive suspension system.
Reduction of body roll makes firing more effective and the possibility of fast change of vehicle velocity makes that vehicle difficult target for artillery.
