Evaluation System for Farmers' Satisfaction Degree in the Green Energy Saving Rebuilding of Rural Residence

In view of the present situation of measuring a green residence just by energy saving and environmental protection,we propose that we should build the rural residence more from the farmer's view and set up an evaluation system based on farmers satisfaction.A total of 16 factors affecting the farmers' satisfaction degree of green energy saving rebuilding of rural residence are selected.Questionnaire survey on 110 peasant households is carried out under different situations in Guanzhong region in Shaanxi Province,so as to obtain the importance score of evaluation index.During constructing the evaluation system for farmers' satisfaction degree,Factor Analysis Method is used to classify the related influencing factors.Subjective analysis of Analytic Hierarchy Process and the objective analysis of Factor Analysis Method are combined together to determine the weights of factors at different grades.Then,the final evaluation model is obtained,which provides guidance for the further green energy saving rebuilding of rural residence in China.

GDOP’s Influence on Observable Degree of Multi-Antenna GPS/SINS Integrated Attitude Measuring System

GDOP’s influence on observable degree is studied by analyzing a multi-antenna GPS/SINS attitude measuring system. Firstly, the mathematical model of the attitude measuring system, whose observations are single-differences, is provided;Secondly, it is proved that the model can be studied by PWCS theory, and GDOP’s influence on observable degree is explained intuitively. Then, the variance of observable degree is studied by simulation while GDOP is different, and the result is analysed. Simulation results show that, the observable degree becomes worse with the increasing GDOP value. Therefore, while designing such kind of Kalman filter, the influence to observable degree which made by GDOP should be considered adequately.

Use Characteristics and Satisfaction Degree of Jinjiang 198 Greenway in Chengdu under the Background of Park City Construction

Greenway construction is one of the important measures for Chengdu to build a “beautiful and livable park city”, and is also a framework system for building a park city. According to the construction demand of the park city, a Tianfu greenway system with the theme of “one axis, two mountains, three rings and seven belts” will be formed throughout Chengdu. Jinjiang 198 Greenway is the first large-scale greenway in the main urban area of Chengdu. In view of the use of Jinjiang 198 Greenway in Chengdu, its use characteristics and user satisfaction degree are studied. The general situation of people's use of greenway is obtained from the characteristics of users themselves and its use conditions. According to the statistics of user satisfaction degree through field survey and questionnaire survey, it is known that the overall satisfaction degree of users on the greenway is good. Through factor analysis, the main factors affecting user satisfaction degree are obtained, which are in turn supporting facilities, service facilities, activity sites,green environment and accessibility. Finally, based on the above analysis and summary, suggestions and opinions are put forward for the future construction and development of Tianfu greenway system.

Predicting User Satisfaction of Non-volitional Enterprise Systems: An Example From Telecomunications

The rapid pace of technological change has seen information and communication technologies become the digital backbone of developed nations’ economies and a pre-requisite for global trade. Some enterprise systems are however more than mere facilitators, they provide the bedrock without which organizations could not function;we term these mandatory systems “non-volitional”(NVS). With hyper-growth in demand for connectivity, telecommunications are typical of sectors where NVS shape the fiercely competitive landscape. Among them, Billing & Revenue Management Systems (BRMS) are a form of credit, providers deliver a service and subscribers later pay for that service. As such, they are “business critical”, meaning failures may affect an organization’s ability to conduct its core business. Failures also impact user satisfaction, a key measure of information systems success. However, relatively few studies empirically test this notion;fewer still evaluate it at organizational (rather than individual) level, while there is a dearth of literature investigating non-volitional systems and, to the best of our knowledge, none whatsoever consider ways of predicting user satisfaction for BRMS. According to a renowned and widely cited conceptual model, user satisfaction is influenced by information, system, and service quality respectively. To test this theory for telecoms BRMS, we applied structural equation modelling to investigate which of these dimensions has the most effect. The results indicate that information quality, system quality, service quality, and user satisfaction are all valid measures of BRMS success. Hypothesized relationships between the four success dimensions were significantly substantiated. The study also identified five measures of information quality, four measures of system quality, four measures of service quality, and four measures of user satisfaction. Once the proposed model had been successfully validated, we tested the level of significance among user satisfaction and the three quality dimensions. Findings showed that service quality had the strongest influence on user satisfaction, with information quality second. This is quite different from other applications considered in our literature review which mostly have information quality as having the strongest impact (knowledge management systems apart).

Level of Acceptance of Industrialized Construction in Brazil by Assessing the Degree of Satisfaction of User

This paper compares the satisfaction of users of residential buildings produced by two construction processes considered as industrialized:“prefabricated masonry panels”and“reinforced concrete walls molded on site”and compared with“conventional process”(structural masonry of concrete blocks).The premise of the study was to diagnose the level of acceptance of the buildings considered industrialized by the Brazilian population,aiming to assess whether the preference for the systems considered“conventional”and the rejection of the“industrialized”is decreasing in Brazil.This article concerns the results obtained in the second phase of the research,which was carried out after five years of the first phase.So,if the buildings were considered new in the first phase,this second research was carried out after the depreciation due to the action of time.To quantify the“degree of satisfaction”the same checklist of the first survey was applied,in the same neighborhood and the sum attributed to each answer made by residents was applied and,as a result,it was possible to ascertain the oscillations in it and to confirm the satisfactory acceptance of industrialized construction systems and a tendency to reduce rejection by the population in relation to the innovative construction systems.

Optimal maneuvering strategy of spacecraft evasion based on angles-only measurement and observability analysis

Spacecraft orbit evasion is an effective method to ensure space safety. In the spacecraft’s orbital plane, the space non-cooperate target with autonomous approaching to the spacecraft may have a dangerous rendezvous. To deal with this problem, an optimal maneuvering strategy based on the relative navigation observability degree is proposed with angles-only measurements. A maneuver evasion relative navigation model in the spacecraft’s orbital plane is constructed and the observability measurement criteria with process noise and measurement noise are defined based on the posterior Cramer-Rao lower bound. Further, the optimal maneuver evasion strategy in spacecraft’s orbital plane based on the observability is proposed. The strategy provides a new idea for spacecraft to evade safety threats autonomously. Compared with the spacecraft evasion problem based on the absolute navigation, more accurate evasion results can be obtained. The simulation indicates that this optimal strategy can weaken the system’s observability and reduce the state estimation accuracy of the non-cooperative target, making it impossible for the non-cooperative target to accurately approach the spacecraft.

Numerical Simulation about the Characteristics of the Store Released from the Internal Bay in Supersonic Flow

To understand the influence of the initial release conditions on the separation characteristics of the store and improve it under high Mach number(Ma=4)flight conditions,the overset grid method and the Realizable k−εturbulence model coupled with an equation with six degrees of freedom are used to simulate the store released from the internal bay.The motion trajectory and the attitude angle of the store separation under the conditions of different centroid,velocity,height and control measures are given by the calculated result.Through analysis,the position of the centroid will affect the separation of the store,which needs to be considered in the design.Increasing the launching height is conducive to the separation of the store.If the store has an initial velocity,it can leave the internal bay more quickly and reduce the probability of collision with the wall.Cylindrical rod and slanted aft wall control measures can improve the attitude of the store and make the store fall more smoothly.

Residents’ Satisfaction Assessment of Outdoor Residential Spaces;A Local Study in an Urban Compact Form in Sana’a, Yemen—Winter Period

This paper studies the thermal performance of outdoor residential spaces in the old part—historical part—of Sana’a city in the winter period and its impact on the residents’ satisfaction who occupied the buildings which overlook these spaces and use them on a pedestrian comfort basis. The analysis was carried out through the results of field measurements which study the temperature, relative humidity, and the air movement inside the selected outdoor spaces in the period of winter (2 months) data recorded through the devices used and compared with those obtained from the General Authority of Meteorology and Aviation—Meteorology Sector. Despite the passage of years, the author remained occupied with the opinion of the people whose homes overlook those outdoors spaces and what is their opinion of their performance. Therefore, an assessment was conducted in November 2020 to know the opinion of the people about the performance of these outdoor spaces and to compare the results of the field measurements with the results of the assessment. The measurements were conducted by using data-loggers that spread in some outdoor spaces in 7 spaces in old city of Sana’a and in its modern extension during the winter period which is the time of concern of this work. The measurements showed that the outdoor residential spaces in the old city of Sana’a are represented an advantage for winter climate over that of the modern city, so the focus in this paper was on that outdoors with the question of the users of the outdoor spaces in the old city only to clarify their satisfaction with it and whether it has succeeded as well from their point of view. Results presented in this paper are important to consider the relationship between the climatical performance of outdoor spaces and the comfort of the residents in the urban environment and give implications for urban planners and architects to improve the climate-based design methodology towards sustainable developments.
