League City, TX is used as an application site. NOAA predicts that sea levels will increase and storm surge will become more frequent along the Texas coast. In the Gulf Coast, sea level projects to rise up to 629 feet by 2100. The Climate Change Armor Toolkit comprises both structural and non-structural mechanisms which are either engineered to block and control heavy floods or rely on natural systems and green infrastructure to attenuate flood waters from frequent storms or hazard flood events. With the application of the Armor Toolkit, 221,921 cubic feet of runoff can be captured, nearly 2,400 new residents are protected, over 3,000 jobs are created, $23 million in physical flood damage can be avoided, and approximately $1.3 billion can be generated in the life cycle benefits of the newly designed community by 2100.</p>","PeriodicalId":69201,"journal":{"name":"城市设计","volume":"19 5","pages":"50-63"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6342505/pdf/nihms-1002374.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36938409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This model shows that either the motor stroke or the motor constant can be increased to reduce the electrical power required to perform an injection. We then present computationally efficient semi-analytical field solutions for a tubular linear synchronous motor, and use them to develop optimized motor designs for minimal jet injection power. A finite-permeability solution is developed and compared to both finite element results and a simplified infinite-permeability solution to validate the model and to establish criteria for choosing the back-iron thickness. We find that optimal jet injector motor configurations favor long stroke lengths, even at the expense of motor constant. However, designs constrained to physically reasonable motor lengths still offer an order of magnitude reduction in input power as compared to existing voice-coil-driven injection systems.","PeriodicalId":69201,"journal":{"name":"城市设计","volume":"38 1","pages":"375-381"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75349646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For energy efficiency, each pole is controlled with voltage driving zero power levitation method. Since the system only has displacement sensors for feedback, to fully control and understand the systems characteristics and disturbances, all axis are observed by disturbance observer and integrated to controller algorithm for better response and robustness, which is achieved multiplying the disturbance observer's output with system gain and feedforwarded.

Pumped storage is a well-established one, and is capable of enhancing the integration of renewable energy sources. Pumped storage has an efficiency between 70-80%, and each of its elements affects it. Increased efficiency is desired especially when operating with renewable energy systems, which present low energy conversion factor (up to 50% - performance coefficient for wind turbines, and efficiency up to 40% for photovoltaic systems). In this paper the most efficient operation points of the induction motors in pumped storage systems are established.

In particular, depending on the developments in magnetic materials, permanent magnet synchronous motors rapidly developing in recent years have found themselves a widespread coverage in applications because of their outstanding features. When the research in the literature is surveyed, it is observed that the vector control of electrical machines is done by means of various methods. One of the most common applications of artificial intelligence used in the analysis of electrical machines is Neuro-Fuzzy, a combination of Fuzzy Logic and Neural Network. In this paper, the vector control of PMSM fed by a matrix converter is modeled and simulated by using PI controllers and Neuro-Fuzzy, one of the intelligent methods.
