Recently, hashing based approximate nearest neighbor search has attracted much attention in large scale data search task. Moreover, some cross-modal hashing methods have also been proposed to perform efficient search of different modalities. However, there are still some problems to be further considered. For example, some of them cannot make use of label information, which contains helpful information...
Distributed energy resources (DERs) and smart loads have the potential to provide flexibility to the distribution system operation. A coordinated optimization approach is proposed in this paper to actively manage DERs and smart loads in distribution systems to achieve the optimal operation status. A three-phase unbalanced Optimal Power Flow (OPF) problem is developed to determine the output from DERs...
Eye localization is a key step in many face analysis related applications. In this paper, we present a novel eye localization method based on a group of trained filters called correlation filter bank (CFB). We formulate the eye localization problem as an optimization problem with a well-defined cost function based on CFB. The CFB is trained with an EM-like adaptive clustering approach. The trained...
The rapid development of the theory and application makes it imperative to find the best strategies to improve the energy efficiency of wireless sensor networks. In this paper, we address the following question: given a multi-to-one wireless sensor network in physical space, what is the optimal routing strategy to enable the energy-efficiency of the network with regard to a given mission and a certain...
Computed tomography technology has wide applications in industrial non-destructive tests, medical fields, and public security. In practice, incomplete projection is often acquired because of limitations on the detection environment, time and cost. Iterative reconstruction algorithm has a major potential to achieve superior results on the reconstruction with incomplete projection data. In this paper,...
From the perspective of system control, the smart and green building is a large-scale dynamic system with high complexity and huge amount of information. Proper combination of the available information and effective control of the overall building system turn out to be a big challenge. In this study, we proposed a building indoor energy and comfort management model based on information fusion using...
Smart buildings are becoming a trend of next-generation's commercial buildings, which facilitate intelligent control of the building to fulfill occupants' needs. The primary issue of building control is that the energy consumption and the comfort value in a building environment are inevitably conflicting with each other. To study the relation between energy consumption and occupants' comfort, a multi-agent...
In this paper, the topology optimization design of two-material micro compliant mechanism that allows for treating local stress constraint is investigated. A mathematical model is constructed in which the mechanical advantage of the mechanism is posed as objective function while displacement constraint, material constraint and stress constraint are considered simultaneously. The element free Galerkin...
In this paper a fuzzy adaptive comfort temperature (FACT) model has been proposed for the intelligent control of smart buildings. A multi-agent control system is applied for the energy management and building operation. Particle Swarm Optimization (PSO) is applied to optimize the set points based on the comfort zone. Integrating a grey predictor to predict outdoor temperature with the FACT model shows...
This paper introduces a novel link-driven, 1 DOF, three phalanges robotic finger. In order to improve the grasping performance of BHG-1 hand which is driven by tendon system, a link-driven finger is proposed. First, the design requirements of new finger are given on the basis of the new grasping scheme of BHG-1 hand. Then, the analysis and optimization design procedure of the linkage for the robotic...
Plastic profiles produced by extrusion die are cooled down and calibrated by calibrators, so it is very important to properly design the cooling system in calibrator for the profile quality. Based on the finite element method (FEM) and the finite difference method (FDM), the numerical simulation of the cooling process is realized for plastic profile within calibrator. The simultaneous shape and topology...
Plastic profiles produced by extrusion die are cooled down and calibrated by calibrators, so it is very important to properly design the cooling system in calibrator for the profile quality. In this paper, considering the cooling channels' location, size, number and the calibrator's material distribution simultaneously, the optimization design of heterogeneous calibrator cooling system is investigated...
A novel multi-step coordinated control approach for microgrid management is proposed considering economic and environmental aspects. The proposed concept consists of a two-layer control algorithm, the component-layer and the top-layer controls. Both are based on look-ahead multi-step optimization techniques. Assuming the availability of renewable power forecasting methods, future states of the microgrid...
A traffic network of a city area is considered in this paper. This paper presents a linear program which is based on optimization from a purely mathematical point of view to solve the problem of optimizing city area traffic control. The phase sequence of each intersection is known. The identification of the optimal phase relationship between all intersections and duration for the signal phases are...
One of the most critical issues in energy-limited wireless sensor networks (WSN) is how to make the most of energy efficient strategies to improve system performance. In this paper the system performance is represented by energy-efficiency and data-efficiency. First the case where all the wireless nodes are distributed uniformly is considered and an optimization problem is set up as well as resolved...
