Quadruped robots, which tend to be heavy can be made lighter by carefully considering the number of actuators and required power. This paper discusses the relationship of the moving functions of quadruped locomotion and the required number of actuators. Using fewer actuators than conventionally need not prevent the quadruped robot from satisfactory locomotion. At the same time, energy saving brings a lighter design, because required actuators and batteries are smaller. This paper discusses several techniques to reduce energy consumption. Combining these discussions, examples of 3-, 5-, and 9-actuator quadrupeds are designed, and experimentally performed good locomotion.

Current consumption of cloud computing has attracted more and more attention of scholars. The research on Hadoop as a cloud platform and its energy consumption has also received considerable attention from scholars. This paper presents a method to measure the energy consumption of jobs that run on Hadoop, and this method is used to measure the effectiveness of the implementation of periodic tasks on the platform of Hadoop. Combining with the current mainstream of energy estimate formula to conduct further analysis, this paper has reached a conclusion as how to reduce energy consumption of Hadoop by adjusting the split size or using appropriate size of workers (servers). Finally, experiments show the effectiveness of these methods as being energy-saving strategies and verify the feasibility of the methods for the measurement of periodic tasks at the same time.

Wastewater treatment plant (WWTP) is the energy-intensive industries. Energy is consumed at every stage of wastewater treatment. It is the main contributor to the costs of WWTP. Analysis and forecasting of energy consumption are critical to energy-saving. Many factors influence energy consumption. The relationship between energy consumption and wastewater is complex and challenging to identify. This article employed the fuzzy clustering method to categorize the sample data of WWTP and analyzed the relationship between energy consumption and the influence factors in different categories. The study found that energy efficiency in various categories was changed and the same influence factors in different types had different influence intensity. The Radial Basis Function (RBF) neural network was used to forecast energy consumption. The data from the complete set and categories was adopted to train and test the model. The results show that the RBF model using the date from the subset has better performance than the multivariable linear regression (MLR) model. The results of this study provided an essential theoretical basis for energy-saving in WWTP.

PurposeThis research paper aims at proposing a framework based on semantic integration in Big Data for saving energy in smart cities. The presented approach highlights the potential opportunities offered by Big Data and ontologies to reduce energy consumption in smart cities.Design/methodology/approachThis study provides an overview of semantics in Big Data and reviews various works that investigate energy saving in smart homes and cities. To reach this end, we propose an efficient architecture based on the cooperation between ontology, Big Data, and Multi-Agent Systems. Furthermore, the proposed approach shows the strength of these technologies to reduce energy consumption in smart cities.FindingsThrough this research, we seek to clarify and explain both the role of Multi-Agent System and ontology paradigms to improve systems interoperability. Indeed, it is useful to develop the proposed architecture based on Big Data. This study highlights the opportunities offered when they are combined together to provide a reliable system for saving energy in smart cities.Practical implicationsThe significant advancement of contemporary applications (smart cities, social networks, health care, IoT, etc.) requires a vast emergence of Big Data and semantics technologies in these fields. The obtained results provide an improved vision of energy-saving and environmental protection while keeping the inhabitants’ comfort.Originality/valueThis work is an efficient contribution that provides more comprehensive solutions to ontology integration in the Big Data environment. We have used all available data to reduce energy consumption, promote the change of inhabitant’s behavior, offer the required comfort, and implement an effective long-term energy policy in a smart and sustainable environment.

City highway tunnel ventilation design is one of the key processes in whole tunnel design. The ventilation design has important influence in ventilation sanitation effect, equipment investment, operations energy consumption and operations cost. On the premise of safety and sanitation, if city tunnel adopts natural ventilation, this can reduce energy consumption, construction cost and operations cost. Combining practical conditions of a project, this paper evaluated three kinds of mechanical ventilation, and analyzed contrastively economic efficiency of the natural ventilation and the jet longitudinal ventilation. At last drew the conclusion that the natural ventilation can reduce the total investment by 30% and has obvious energy-saving efficiency, then put forward the pertinent suggestions to the ventilation construction of highway tunnel.

The traditional opinions regard energy as the main factor for the economic development, but not the key one, because there are different conclusions from the practical researches on the relationship between the energy consumption and economic development. The article utilizes the Granger casual test and Cointegration test to analyze the dynamic relationship between energy consumption and economic development in China. Based on our conclusion that economic development relies on energy consumption, some suggestions are given for energy saving and development in the long-term.

Abstract. In view of the status of existing buildings in northwest of Liaoning, most of which are lack of energy-saving practices and appear poor comfort, this paper starts from the energy saving concept, aims at figuring out the energy saving measures for cold regions, such as northwest of Liaoning province. The research includes analyzing energy-saving methods, steps and initiatives. Based on these, this paper also proposes specific technical practices to overcome the shortcomings of the existing buildings on energy conservation, and gives advices on how to reduce energy consumption and improve the quality of people’s living and working environment.

The year 1973 was a breakthrough year in the development of architecture. It triggered a crisis in society as well as the end of a period of relative prosperity and wasting of energy, which until then did not constitute a limiting factor. The crisis has forced to seek a new and more efficient architecture. The following decades were each in their own way characteristic particular in how architects approached to reduce the energy consumption of buildings and how they resolved the relationship of the building to the surrounding and the environment at all. My paper maps ecological ideas in architecture in Slovakia on the background of broader context. Initial decade was about searching and experiments. Mainly theoretical and research projects appeared. In the following period, first projects implementing ecological ides were built, e.g. experimental residential house in Holíč or solar house in Levice. Ecological aspects in architecture ascended to the real centre of interest in Slovakia from the 90s. After the change of political situation, sustainability was perceived more intense, as evidenced by a greater number of ecological houses of this period. Alternative building materials as well as the effort to reduce energy consumption were the driving force to the design of new buildings. New ideas often associated with an endeavor to define an appearance of ecological architecture are observable in many buildings, e.g. clay houses or solar collector house in Zvolen. My paper documents the development of sustainable architecture in Slovakia from the first attempts to the standardization of sustainable architecture with characteristic examples of ecologically conscious architecture of mentioned periods.
