The purpose of this paper is to establish an evaluation system to evaluate space vitality objectively using analytic hierarchy process (AHP). Through an extensive literature review, a preliminary list of evaluation criteria was obtained and used to construct an AHP model. An AHP survey was then conducted with architecture students to calculate the weight of each evaluation factor. Also, the model was applied to Toproint, a small town near Tamar River in UK, to test its applicability and identify the spatial features in the chosen sites.

A novel damage detection approach based on Auto-encoder neural network is proposed to identify damage in beam-like bridges subjected to a moving mass. In this approach, several sensors are used to measure structural vibration responses during a mass moving across the bridge. An auto-encoder (AE) neural network is designed to extract features from the measured responses. A fixed moving window is used to cut out the time-domain responses to generate inputs of the AE neural network. Moreover, some constraints are applied on the hidden layer to improve the performance of the AE network in training process. When the training is complete, the encoder was regarded as a feature extractor. And the damage index is defined as the cosine distance between two feature vectors obtained from adjacent data windows. By moving the window along the measured vibration data, we can calculate a damage index series and locate the damage position of the structure. To demonstrate the performance of the proposed method, numerical simulation is carried out. The results show that the proposed method can accurately locate both single and multiple damages using acceleration response. It infers the proposed method is promising for structural damage detection.

Overlooking the section of the Silk Road in Xinjiang, as the largest span of linear, multi-dimensional cultural landscape, historical heritage and ecological corridor in Xinjiang, it is a huge heritage complex of human culture influencing on the natural landscape. This paper introduces the concept of cultural landscape corridor, taking into account the organic connection between landscape ecology and heritage protection, strengthens the understanding of local social structure and regional culture in Xinjiang, spatially integrates cultural landscape and linear historical relics.

By analyzing the philosophical thoughts of "Great Truths Are All Simple" of Eastern Taoism and the design philosophy of "Less is More" born of Western modernism, the design concept of "simple aesthetics" was proposed.And from the five aspects of form, color, material, detail, attitude, and combing the application of the "simple aesthetics" design concept in the interior design under the fusion of Eastern and Western cultural backgrounds, it is concluded that the "simple aesthetics" design concept meets the needs of the times and artistic aesthetics, the positive meaning of the human spirit.

In this paper, the UAV photogrammetry data of two hills and two flat sampling areas are selected. The image data are processed by pixel Grid software through different operation methods, and the effect of the two methods is compared. The results show that: after the distortion correction, the image is rotated manually or the flight angle in the pos data is directly changed, which has no obvious effect on the error in the number of iterations of the automatic connection point. When the distortion correction is not corrected, the photo is rotated, and the angle of the Omega, Phi and Kappa angles is obtained from the UAV autopilot system, and makes the corner element higher precision when the automatic connection point is generated. Add Kappa to the POS data by 90, and then correct distortion at the same time choice of rotating pictures; Set the Omega, Phi is 0, Kappa angle from the IMU, this method avoids the influence of the angle deviation caused by the tilt or jitter of the flight process, so it is better to line elements when the automatic connection point is generated.

According to the site condition of one of the oversea project located in the low-lying and swamp area, special fine sand with fine modulus in values of 0.42-0.62 was used to construct roads in the area through special workmanship and construction techniques. Bamboo materials are designed as piles and supporting system in a reasonable arrangement. The paper provides calculation details of the supporting system of bamboo materials, outlines the construction procedures and construction technique, and describes the contents of quality control and safety construction. It provides good references for road construction in low-lying and swamp areas in similar countries.
