A square is an important multi-functional public space on campus, which can be used as a venue for traffic, gathering, recreational activities and cultural events, and thus the thermal environment of the campus square will directly influence the overall environmental quality of campus. This paper studies a campus square in the summer-hot and winter-cold region, selects typical positions to conduct actual measurement of parameters, such as temperature, relative humidity, wind speed and solar radiation, which indicate the thermal environment. Based on data collection and analysis, it is concluded that the thermal environment of the campus square is affected by microclimate factors such as the square underlying surface properties, vegetation and building and road orientations. This paper is aimed at exploring the regularity of the correlation between microclimate factors and thermal environment in order to facilitate the improvement of the thermal environment of the campus square, make it more comfortable and provide ideas for the landscape and architectural environment design.

Measurement And Analysis

Open space is an important part of Campus, also has an important influence to the thermal environment of campus. The measurement of summer outdoor thermal environment of campus open space showed that: the piloti can effectively improve the thermal environment in hot summer; underlying surface materials, sky view factor has a great influence on the outdoor thermal environment. Using appropriate surface structure, increasing piloti and increasing square shading are suggested as outdoor thermal environment optimizing measures based the measure results. Advices were given for hot environment design and passive energy saving design

The STAR-CCM+ technology is also used to analyze the location and number of vents in hull coating plant in the case of constant air volume. By means of numerical simulation and mathematical model theory, this paper makes a comparison of air distribution in the working area of this plant, and found the interior velocity and temperature field vary with different location and number of vents. Specifically speaking, the lower position and improper number of vents can lead to unevenness of the internal thermal environment and imbalance of wind speed in the working area. This study provides simulated basis and technical references for the better coating operations in suitable environment, which is significant for putting forward the improvement, optimizing the quality of the coating operation and saving energy.

As an important type of folk houses with the historical and cultural value in China, the mountainous residence is occupying an important historical position in the rapid urbanization. Whereas, traditional dwellings in Chongqing are in an "overload" condition and poorly indoor comfort. With the help of BIM technology, we can simulation analysis of the ambient temperature, the age of air, wind speed and wind pressure, soughting to a method of quantitative analysis of mountain traditional houses, and the design of ecological energy-saving.

Microclimate Environment

The thermal environment of village public space affects the comfort of people ’ s outdoor activities, and then affects the willingness of residents to outdoor activities, which has an important impact on the villagers’ quality of life. Previously published studies of thermal comfort mostly focused on the evaluation of thermal comfort index, few studies on the application of thermal comfort planning. The study was carried out in Maling Village, Changdai Town, Mengjin County, Luoyang City, Henan Province, China. Square, street, green space were chosen as three typical public spaces where thermal comfort indexes were measured by questionnaire survey and field measurement during summer. Subsequently, the village’s microclimate environment was simulated with ArcGIS 10.6 and ENVI-met. The results indicate that during the summer, the influences of temperature, solar radiation, wind speed, and relative humidity on the subjective comfort conditions of the outdoor environment gradually decreased. The spatial form of village has an important influence on thermal comfort. Finally, based on the results, this study put forward the thermal comfort process and planning scheme of the village outdoor space.

Wind forecasting is one of the best efficient ways to deal with the challenges of wind power generation. Due to the depletion of fossil fuels renewable energy sources plays a major role for the generation of power. For future management and for future utilization of power, we need to predict the wind speed.  In this paper, an efficient hybrid forecasting approach with the combination of Support Vector Machine (SVM) and Artificial Neural Networks(ANN) are proposed to improve the quality of prediction of wind speed. Due to the different parameters of wind, it is difficult to find the accurate prediction value of the wind speed. The proposed hybrid model of forecasting is examined by taking the hourly wind speed of past years data by reducing the prediction error with the help of Mean Square Error by 0.019. The result obtained from the Artificial Neural Networks improves the forecasting quality.

Quality Issues

Policing is increasingly being shaped by data collection and analysis. However, we still know little about the quality of the data police services acquire and utilize. Drawing on a survey of analysts from across Canada, this article examines several data collection, analysis, and quality issues. We argue that as we move towards an era of big data policing it is imperative that police services pay more attention to the quality of the data they collect. We conclude by discussing the implications of ignoring data quality issues and the need to develop a more robust research culture in policing.

Patterns Of Recurrence

Abstract BACKGROUND There are global variations in radiotherapy approaches for icGCT. An understanding of patterns of disease recurrence correlated with radiation techniques and doses is important in standardising and improving the quality of radiotherapy using high-precision techniques. METHODS AND RESULTS Data from 20 patients with tumour recurrence after treatment within the SIOP GCT96 study in the UK were analysed. Seven (35%) patients had germinoma and 13 (65%) had non-germinoma. Twelve patients had local recurrence, 5 had metastatic and 3 had local and metastatic disease. Radiotherapy details were retrieved in only 8 patients (40%). Six patients had received focal radiotherapy and two craniospinal radiotherapy. Of the patients who received focal radiotherapy, 4 had recurrence within the radiation portal, one had periventricular recurrence and one had marker-positive recurrence with no radiological lesions. Both patients who received CSI recurred within the CSF space. The main reasons for poor retrieval of treatment details were difficulty in retrieving archived information and that the study was conducted during a period before PACS or electronic radiotherapy records. CONCLUSION This study highlights the importance prospective data collection and analysis to understand the patterns of recurrence in icGCT. Even within a prospective study, radiotherapy techniques varied between centres. There is therefore an urgent need for centralised radiological review and prospective radiotherapy quality assurance measures in future clinical trials.
