The integrated energy system is the main physical carrier of the energy Internet. Planning is the leading link of its application, which directly affects the necessity and economy of the construction of the project. Firstly, the basic process of integrated energy planning is summarized. Then, three application challenges faced by urban integrated energy system planning are summarized from the perspective of engineering application: integrated energy system refinement modelling, multi-energy load integrated prediction, and expansion of planning boundaries. The corresponding strategies are given for the above challenges, and the development of integrated energy system planning and application is prospected, which provides reference for the staff engaged in urban integrated energy system planning and related investors.

One-solving methods and techniques necessary to avoid inefficiencies and not economic costs as well as reduce the cost of housing construction is the method of Value Engineering. Value engineering is a method and cost control techniques to analyze a function to its value at the lowest cost alternative (most economical) without reducing the quality desired.At the writing of this study used a comparison method by comparing the initial design to the design proposal of the author. In the housing projects Upgrading Tirto Penataran Asri type 70, the application of Value Engineering conducted on the job a couple walls and roofs pair by replacing some work items with a more economical alternative but does not change the original function and high aesthetic level and still qualify safe. For that performed the step of determining a work item, the alternative stage, the analysis stage, and the stage of recommendations to get a Value Engineering application and cost savings against the wall a couple of work items and partner roof.The proposed design as compared to the initial design. Work items discussed was the work of a couple wall having analyzed obtained savings of Rp. 2,747,643.56 and the work of the roof pair obtained savings of Rp. 2,363,446.80. Thus the total overall savings gained is Rp 5,111,090.36 or savings of 0048%.

The science and engineering of water resources in developed countries has undergone profound changes in less than a professional lifetime. This has radically influenced education and research and essentially revolutionized water resource planning. Fundamental uses of water to fulfill society's needs continue. These include domestic and industrial supplies, waterways for transport, fire protection, waste carriage, recreation, irrigation, and in general, an adequate quantity and quality of water in the right place at the right time to fulfill human and aquatic needs. The complexities of water resources no longer may be measured largely in terms of science and engineering challenges alone, but must include economics sensitive to the political and social sciences. What has evolved is what is now best described as water management. This paper reviews the evolvement of water resources management in developed counties in terms of historical background, and national policies and institutions, particularly as this evolvement impacts scientific research and engineering application.

Stem cell transplantation is an advanced medical technology, which brings hope for the treatment of some difficult diseases in the clinic. Attributed to its self-renewal and differential ability, stem cell research has been pushed to the forefront of regenerative medicine and has become a hot topic in tissue engineering. The surrounding extracellular matrix has physical functions and important biological significance in regulating the life activities of cells, which may play crucial roles for in situ inducing specific differentiation of stem cells. In this review, we discuss the stem cells and their engineering application, and highlight the control of the fate of stem cells, we offer our perspectives on the various challenges and opportunities facing the use of the components of extracellular matrix for stem cell attachment, growth, proliferation, migration and differentiation.

Background: In order to study the interference of wired transmission mode on robot motion, a mobile robot attitude calculation and debugging system based on radio frequency (RF) technology is proposed. Methods: Microcontroller STM32 has been used as the control core for the attitude information of the robot by using MEMS gyroscope and accelerometer. The optimal attitude Angle of the robot is calculated through nRF24L01 which is the core of the wireless communication module, attitude acquisition module and wireless data communication upper computer application platform. Results: The results shows that the positioning accuracy is better than±5mm. Conclusion: The experimental results show that the proposed attitude solving and debugging system of mobile robot based on RF technology has better reliability and real-time performance. The propped model is convenient for debugging of mobile robot system and has certain engineering application value.
