Based on the reality of urban traffic and that some intersections are relatively narrow, a CA model is established by setting the right turning lane in the parking line. Different from other models, the control of signal lights and the mixed traffic flow of motor vehicles and non-motor vehicles are considered, and the rule of non-motor vehicle courtesy and non-motor vehicle occupation rules for pedestrians crossing the street are also introduced in the model. Based on the model, the conflict relation and comity behavior between the crosswalk and the mixed traffic of non-motor vehicles are studied. At the same time, this paper also studies the influence of queue of some non-motor vehicles on traffic capacity at intersections. Furthermore, according to the new model the conflict between right turning motor vehicles and non-motor vehicles at the intersection is studied. The results show that both of the number of direct non-motor vehicles and the right-turn motor vehicles lead to the increase of conflict between VDOC(vehicle declaration occurrences caused by conflicts) and NMDOC(non-motor vehicle declaration occurrences caused by conflicts), while the increase of right-turn vehicles also makes DOP(declaration occurrences caused by pedestrians) conflict increase.

Aiming at the problem of traffic congestion between toll station and the adjacent intersections, a coordination control method based on the Webster’s delay model for toll station and the adjacent signalized intersection was proposed. Firstly, the traffic demand of the intersection and the toll station in the next signal cycle was forecasted through detecting the basic traffic flow data of upstream. Then under the constraints of preventing the ramp, the toll station and the signalized intersection from congestion, with the objective function of average delay time of vehicles in the whole area, a coordinated control model for toll station and the adjacent signalized intersection was built, which makes capacity matching by coordination control of the actual capacity of the entrance and exit of the toll station and the signal timing of the intersection, and through the setting of the weight coefficient, priority will be given to clearing the queuing of the entrance and export traffic. The case simulation results show that the method can effectively alleviate traffic congestion which provides a theoretical method for the coordination control of freeway entrance and exit restriction and urban road signal.

With the degree information of a node and its neighbor nodes, a new node capacity load model is proposed, which is applied to the study of cascading failures in the western power grid in the United States and other grids. In the simulations, the power grid are designed to be attacked by the highest load node (HL attack) and the lowest load node (LL attack) respectively. The results show that the power grid with the improved load model has better robustness and resistance to destruction compared with the traditional capacity load model based on the node degree. Through the study of the ratio of the sum of the neighboring degree values of the attacked node to its own degree value, it is well explained that the new model can reduce the scale of cascading failures in the network.

In recent years, N-path filters have been widely used in many fields such as radio frequency communication and cognitive radio. In order to reduce the loss and noise of the filter and expand its tunable range, this paper introduces series inductance into the traditional first-order N-path filter, and cascades them to obtain a high-order N-path filter with low loss, low noise and wide tuning. The transfer function of the high-order N-path filter is obtained by the adjoint network method. The use of the adjoint network method greatly simplifies the mathematical derivation of the transfer function. The Cadence simulation results in the TSMC 0.18 μm CMOS process show the correctness of the transfer function. The Cadence simulation results also show that when the power supply voltage is 1.2V, the adjustable range of center frequency of the high-order N-path filter is 0.4-3.0 GHz, the insertion loss is 1.6 dB, the return loss is 11.6 dB, and the noise figure is 0.2-0.8 dB. Compared with the published filter, the comprehensive performance of the new filter has greatly improved, and it can be applied to a high-performance receiver.

Robust stability of a class of cellular neural networks with time-varying delays and uncertain parameters is studied. With the help of the convex combination method, the unequal division of the time delay interval is achieved, the introduction of parameters reduces the limit of the time delay derivative by less than 1, and the introduction of new variables can implements the treatment of uncertain terms. By combining the Jensen inequality with the convex combination method, a new method for the integral interval is obtained. The final numerical example verifies the validity of the conclusion.

In information extraction, relation extraction is a key technology to accurately identify the relationships between entities in natural language. Aiming at the problem that the key semantics in the relation extraction model are easy to lose and the basic assumptions of remote supervision are easy to introduce noise data, an ENCODER_ATT relationship extraction model based on remote supervision is proposed. Firstly, the ENCODER model based on the construction of the cyclic neural network extracts the feature memory at the word level and integrates the semantic feature information at the sentence level to ensure that the key features are removed without removing the redundant features. Secondly, attention mechanism is introduced at the sentence level to reduce the influence of noise data on the test results. Based on the actual experimental data, the experiment was carried out and the accuracy-recall rate curve was drawn to prove that the ENCODER_ATT model has a better improvement over the relationship extraction method of the same type.

Aimed at the pedestrian detection speed and related practical application problems, a fast multi-feature pedestrian detection method is proposed and applied to video monitoring system in this paper. Firstly, the Gaussian modeling is used to extract the effective motion region of the image, so that the detection area is reduced. Then, the extracted image is edge-processed, the HOG feature is merged with the LBP feature, and the classifier is trained using the support vector machine (SVM). Finally the pedestrian detection algorithm on the Hi3516A development board is conducted to monitor and detect in real time. Experiments are carried out on the PC side and the development board respectively. It is show that the method effectively improves the speed and achieves the real-time pedestrian detection requirements. The system runs stably and can be used in actual monitoring.

To solve the problem that the segmentation effect of log image with small difference between background and foreground color is unsatisfactory, an image segmentation method based on fuzzy C-means clustering and Otsu is presented.Firstly, standard log database is used as sample and the log sample image with small difference between background and foreground color is segmented into two categories by using the fuzzy C-means clustering algorithm.Secondly,the criterion function is used to obtain the result of foreground segmentation. Finally,the result is used as input of Otsu algorithm to form the final segmentation of log sample image.The experimental results show that the proposed algorithm is better than the single fuzzy C-means clustering algorithm. Otsu and similar algorithms have better segmentation effect and higher segmentation accuracy, the edge information is well preserved and the average segmentation accuracy is increased by 2 percentage points.

A subgroup H of a finite group G is called a CAP^*-subgroup of G, if H either covers or avoids every non-Frattini chief factor of G. A subgroup H of G is said to be a nearly CAP^*-subgroup of G if there exists a subnormal subgroup K of G such that HK=G and H∩K is a CAP^*-subgroup of G. This paper investigates the structure of G under the assumption that certain subgroups of prime power orders are nearly CAP^*-subgroups of G, and a series of known results are generalized.

The analgesic effect of ADE was evaluated by a series of pain models, in which the pain behaviours were induced by tail immersion, thermal radiation, capsaicin and formalin tests, and Von-Frey mechanical stimulation, respectively. The primary cell culture and calcium imaging technique were then employed to investigate the functional mechanism of ADE in neurons from dorsal root ganglion (DRG). The results showed that the ADE substantially attenuated the acute pain induced by thermal, capsaicin, and formalin in mice. However, ADE did not suppress the thermal-or capsaicin-induced acute pain in Trpv1^-/- mice. Moreover, ADE significantly inhibited the intracellular influx of Ca²⁺ induced by capsaicin in the TRPV1-positive DRG neurons. So these findings suggested that ADE exhibits an analgesic effect in pain models by reducing the activity of TRPV1.

(4) The R/T value showed that the families and genera of P. massoniana plantations in four different forest ages are of tropical nature, and the R/T value decreased with the increase of forest age.

The specimens of Guangxi Chongzuo White-headed Langur Nature Reserve were collected with line transect method and litters screening method, 98 species belonged to 52 genera of 8 subfamilies of Formicidae. Among them 4 species were new records to Guangxi. Faunal analysis of species components suggested that: in zoogeographical region of the world, the ant fauna of the Reserve has typical characteristics of oriental region. Oriental and Palaearctic regions have the highest ratio, so the ant fauna of the Reserve is closest to the Palaearctic region, and farthest to the Neotropical region. In the zoogeographical regions of china, the ant fauna of the Reserve has typical South China characteristics. South, Southwest and Central China regions have the highest ratio, so it is closely related to the Central and Southwest China regions.

Ecological land is an important carrier to maintain human health and social sustainable development. Research on the change and driving force of ecological land use is beneficial to regional ecological planning and ecological civilization construction. Remote sensing monitoring data of land use in 2005, 2010 and 2015 were used to construct the spatial autocorrelation model of ecological land use change based on the first law of geography. This paper analyzes the ecological land use change and its extension mechanism in the Beijing-Tianjin-Hebei junction area. The results showed that: (1) By the end of 2015, the area of ecological land in Beijing-Tianjin-Hebei junction area was 13 049.71 km². Among them, cultivated land accounted for 52.42%, woodland, grassland and water area accounted for 32.26%, 10.05% and 5.27% respectively, and the cultivated land was mainly distributed in southern plain area in the study area, and the northern mountain woodland agglomeration. (2) During the study period, the ecological land decreased by 193.13 km², and the main loss direction was construction land, and the cultivated land decreased the most, accounting for 95.04%. (3)The spatial autocorrelation between ecological land and construction land increased and the spatial aggregation gradually strengthened. (4)Population density, total power of agricultural machinery and grain yield were the most important factors to cause the change of ecological land use, indicating that the degree of population agglomeration, agricultural mechanization level and the efficiency of arable land has an important influence on the ecological land. Optimizing resource structure and improving land use pattern are of great significance to promoting regional sustainable development and ecological civilization construction.

Satellite precipitation data is becoming a very popular data source for many application fields. Based on previous research, a series of regression models are built of between TRMM 3B42V7 and terrestrial environment factors (NDVI, GDP, urbanization rate, population and DEM) through using their correlation in Beibu Gulf Economic Zone. Then 3B42V7 precipitation products from 2000 to 2008 were downscaled and their spatial resolution were improved to 250 m×250 m. 27 meteorological stations were used to validate the downscaling results, the accuracy (relative error) of downscaling results versus 3B42V7 is reduced by 0.93% and coefficient of determination (R²) is reduced by 0.05, which is negligible against the big promotion in spatial resolution. Therefore, the downscaling method is applicable to the Beibu Gulf Economic Zone.
