The novel routing algorithm can dynamically choose routing according to the residual energy of the sensors and the sensors with more power is taken more data transfer tasks.
Each node maintains a list of coordinates of its neighbor nodes, and the table information can be refreshed by exchanging data periodically with neighbor nodes.
Conversely, Although a small value can improve the randomness and global search capability, it will inevitably bring about the reduction of the solution quality.

Virtual methods to assess the fitting of a fracture fixation plate were proposed recently, however with limitations such as simplified fit criteria or manual data processing.
However, data collection were performed manually, which requires long processing time and has higher possibility for error by the operator.
By automating the process, accurate and speedy data collection is possible.
Therefore, more time could be spent for extended data analysis to provide further information on an implant's fitting based on quantitative measures.
Second, to investigate the extent of borderline fitting cases for a tibia plate by performing extended analysis on the data collected based on the automated fitting method.

Clinical data indicate the possibility of more rapid wound closure and subsequent healing in zones treated with LLLT as compared with control.
The conservative periodontal therapy can lead to predictable pocket reduction and stop further disease progression.
Their histological data showed that both healing and homogenization of the gingival lamina propria improved after LLLT.
Clinical data sugest the possibility of more rapid wound closure and subsequent healing in areas receiving LLLT as compared with control group.

To ensure the reliability of the data, there are three specimens with each of the same experimental conditions.
But in this research, there are two points we should pay attention to, one is the healing of the pore clusters and the increase of compactness after the treatment, the other is the reduction or disappearance of the γ phase.
And because of the disappearance or reduction of the pore clusters after the treatment, the quantity of micro-crack sources reduce.
It leads to the sharp reduction of the density of the radiated cracks.
This means that the interface bonding strength is improved owing to the reduction of the density of the radiated cracks and the improvement of the fracture toughness.

However scientific data is often not given.
The following requirements were defined in consultation with GROB-Werke: - mass reduction of at least 50 % - at least same structural stiffness in all directions - retention of space requirements x φ down up down up down up translational motion translational motion φ [°] x [mm] 0 50 100 5000 10000 0 5 10 15 20 Time [s] Figure 2: Typical process of the pick-and-place unit Technical measurements and modelling The conventional arm was extensively investigated.
Table 4: Modal analysis of CFRP arm Experimental Simulation Mode Frequency Damping Frequency Difference 1 835 Hz 0,6 % 862 Hz 3,2 % 2 857 Hz 0,9 % 899 Hz 4,9 % 3 1046 Hz 0,9 % 1011 Hz -3,3 % 4 1356 Hz 1,0 % 1334 Hz -1,6 % Furthermore, the mass of the CFRP arm is 65 % lower than the steel arm’s mass which consequently leads to a moment of inertia reduction of 68 %.
The following results could be achieved: - mass reduction of 65 % - mass moment of inertia reduction of 68 % - increase of rigidity in positioning direction by 10 % - increase of carrying capacity by 20 % - first eigenfrequency increased by 80 % - increase of damping of the first eigenfrequency by 30 % Using the presented construction method, an increase of the usage of CFRP components in machine tools is to be expected and recommended due to the high potential of this alternative material.

Spectroscopic analysis was performed using a spectrophotometer Shimadzu RF-5301PC model, computer interfaced for recording the data and samples were in powder form.
By infrared analysis, it was discovered that there was a modification in the strength of the bands increased with time of calcination, as witnessed in the characteristic bands of the group O-H at 3446 cm-1 and 3529 cm-1, which were more intense for 2 hours when one compare with the condition of 6 hours, which may be related to reduction in the presence of organic waste from organic precursor PVA [11].
It was observed after 6 hours of calcination an reduction in the bandwidth and splitting at 1423 cm-1 which increased its relative intensity, as compared to the sample with 2 hours of calcination.
An explanation for this lack of crystallinity may be related to the entry of the europium ion in its +3 oxidation state, because no reduction was observed of the dopant in the oxidation state +2.
On the other hand, the reduction of europium ions in its +2 oxidation state has a size of the radius of 1.21 Å, which is close to the Sr+ 2 radius 1.20 Å.

Interrelated improvements in electrical and physical characteristics of nitrided SiC-SiO2 interfaces include: reduction in the interface-trap density [2-7], reduction in carbon clustering [8], reduction in suboxide bonds at the interface [9,10], increase in the semiconductor-oxide barrier height [11], increase in carrier mobility [12-15], improvements in reliability [16,17], reduction in interface roughness [18], and apparently the largest effect - dramatic lengthening of retention of nonequilibrium charge in MOS capacitors [19,20].
Given that vth=(3kT/m) 1/2, the first-order equation for the temperature dependence of sg is TAs sg = (4) Experimental data indicate much stronger than linear temperature dependence, so exponential dependence for σn,p was used in an initial analysis of sg and τg in 4H SiC [33].

Today promoting the EER ability has become one of the most emergent tasks which is directly related to the successful or not for the whole earthquake disaster reduction of China.
However, there is just the concentrative region of relative EER ability(green and yellow regions).The result shows that we will not only notice the EER function ,but also focus on the function if or not meet the disaster-reduction demand, that is, the facing risk of earthquake disaster.

Some tests show that indoor unconfined compressive strength of soil cement reduces with the increase of water content and that, in general, strength of soil cement increases by 10%~30% correspondingly with every 10% reduction of water content [6].
Test design To explore the impact of reduction of cement ratio and remixing condition on pile-forming quality under a certain soil property condition, construction and quality tests of standard test pile and defective test pile are conducted in subgrade reinforcement section of the new construction work of an ordinary highway which is located at soft soil distribution area of southern regions of Jiangsu.
To reduce the contingent factors of test data, there are two test piles in each group.
Table 2 Comprehensive Scoring Results of Standard Test Pile and Defective Test Pile Type of test pile Standard test pile Defective test pile No. of group of test pile T0 T1 T2 T3 T4 T5 Scoring according to Provincial Standard 100 85.2 87.6 68.7 70.2 54.3 Descending rate of defective test pile compared with standard test pile (%) 14.8 12.4 31.3 29.8 45.7 Quality level Excellent Good Good Qualified Qualified Unqualified Scoring based on standard test pile 100 69.9 74.5 48.6 49.5 24.8 Descending rate of defective test pile compared with standard test pile (%) 30.1 25.5 51.4 50.5 75.2 Research shows that serious construction quality problem, such as relatively dramatic reduction of cement content, and sharp reduction of frequency of mixing, may happen when the Provincial Standard is applied in quality evaluation on cement mixing pile in different soil layer conditions, because soil quality has strong impact on mixing pile and the variation of soil layer conditions in different regions

Due to the debilitating effect of biological and mineral fouling on the optical windows, the in situ development period and data quality of moored radiometer have been very limited, especially in coastal waters.
A motor drives the mechanism of this device to periodically rotate for cleaning, move entirely from the optical window for data collection and completely cover the optical window for window protection.
Data are collected for about 10 min and then the device is swung back over the optical window to keep the optical elements protected from biofouling between measurement intervals.
Data collected from this radiometer showed no apparent signs of degradation in quality.
The antifouling device described in this paper is intended for both open and coastal ocean deployments and enable to facilitate high quality data return.
