We present a new value of the Newtonian gravitational constant $G$ by using time-of-swing method. Several improvements greatly reduce uncertainties: (1) measuring anelasticity fiber directly; (2) spherical source masses minimizes effects density inhomogeneity and eccentricities; (3) quartz block pendulum simplifies its vibration modes uncertainty inertial moment; (4) setting both in vacuum chamber reduces error relative positions. By two individual experiments, we obtain $G=6.673\text{...
With the development of intelligent algorithm, GA and PSO have become hot spot for study on multi-objective optimization in recently years. Information sharing is core Comparing with GA, algorithm has less variables to adjust easy achieve, so it widely used engineering. This paper focus comparation several introduce a kind that better performance than others.
The density inhomogeneity of a glass pendulum is determined by an optical interference method. relative variations the densities over volume with sizes 5 × mm3 are (0.64 ± 0.97) 10−5 and (0.99 0.92) for K9 silica pendulum, respectively. These contributing to uncertainties Newtonian gravitational constant G 0.20 ppm 0.21 in our experiment on measurement G.
Stock index futures has become the major tools for investors to avoid risk or make speculative arbitrage. However, leverage of stock is large. If they cannot a correct judgment on trend futures, loss will be great. This paper based this background and engages in intensive study. Using traditional modern econometric methods respectively, CSI 300 were fitted. In addition, RMSE (root mean square error) was used find optimal model. After finding model, we can put trading strategy forward.
The rapid development of modern cold chain logistics technology has greatly expanded the sales market agricultural products in rural areas. However, due to uncertainty product harvesting, relying on experience values provided by farmers for vehicle scheduling can easily lead low utilization capacity during pickup process and generate more transportation cost. Therefore, this article adopts a non-linear improved grey prediction method based data transformation estimate demand fresh products,...
The cellular D2D heterogeneous network takes advantage of proximity gain and hop communication, which can greatly improve the performance entire network. actual imposes an ultra-reliable low-latency requirement for communications. Therefore, this paper proposes a set joint power control resource allocation distributed solutions. It consists two parts. In order to guarantee quality-of-service (QoS) primary users scheduled users, pricing-based game scheme is used. achieve requirement, link...
To improve the adaptability and stability of Dijkstra algorithm for solving routing problem service composition, a method to solve composition based on an improved ant colony is proposed. Firstly, traditional algorithm, constraints it are improved. Secondly, model established, process presented. Finally, simulation experiment will show that more applicable in composition.
Fuel cell technology based on natural gas is a kind of promising and cleaning energy conversion under development. The generation mechanism fuel different from the traditional power device, efficiency not restricted to Carnot cycle, therefore, it has almost highest in most device. as motor building cogeneration system integration high type with utilization method. In this paper, Solid oxide (SOFC)-based Building Combined Cooling, Heating Power (BCHP) simulated, can meet basically electrical...
Abstract A collaborative planning model for electric vehicle (EV) charging station and distribution networks is proposed in this paper based on the consideration of mobile energy storage. As a load, EVs can interact with power grid. Taking as considerations, subsidies are used to shift load feeder network area large margin, reducing transformer capacity overall cost. Finally, article uses CPLEX solve optimization problem, an 18-node system simulation verification.
Liver cancer is the fourth leading cause of death in world, and it even more serious China, occupying over 50% new cases deaths worldwide. One major challenges surgery remains complete removal tumor. Therefore, numerous studies have proposed to design automatic systems aimed at supporting physicians during surgery. As an optical imaging modality, hyperspectral (HSI) simultaneously captures spatial spectral features bring additional insight surgeons a label-free manner. However, best our...
