In this paper, we address energy management for heating, ventilation, and air-conditioning (HVAC) systems in buildings, and present a novel combined optimization and control approach. We first formulate a thermal dynamics and an associated optimization problem. An optimization dynamics is then designed based on a standard primal-dual algorithm, and its strict passivity is proved. We then design a...
Gaofen-5 (GF-5) satellite is designed to provide high resolution imagery for land observation and disaster monitoring and will be launched in 2017. As true GF-5's data is unavailable, image simulation can be a useful tool to provide test images for research on relevant key techniques. In this paper, an emissivity image simulation method is proposed for 4 thermal infrared (TIR) bands on one of GF-5's...
The Internet of Things (IoT) consists of networked objects deployed worldwide and connected over the Internet. As a consequence, the major aspects of the IoT are represented by the heterogeneity and the huge number of the participating devices. These aspects also constitute the major challenges in the definition of a storage infrastructure suitable for IoT applications. In this paper, we introduce...
The third-party enterprises, such as sociologists and commercial companies, are mining data published from online social network (OSN) websites (e.g., Face book, Twitter) to serve their diverse purposes. This process leads to critical user concerns over their privacy, especially sensitive relationship with others on OSNs. Existing anonymization techniques in publishing online social data are focused...
According to the lower Yellow River mathematical model features, the paper presents the water and sediment data model based on the object-oriented data modeling method. By anglicizing various data types, defining the properties and their relationship, this model can adapt to the lower Yellow River mathematical model features. Taking the river part from Huayuankou to Lijin as the experimental zone,...
Constraining by cameras' view-angles of the outdoor monitoring systems, the panoramic digital images fail to be obtained directly from photographing. A method is proposed on the basis of the scale invariance feature transform (i.e. SIFT) algorithm to stitch images captured by the turning video cameras together to form panoramic images. Based on the SIFT features and the retrofitted KD-Tree structure,...
In wireless sensor networks, sensor nodes are densely deployed for environmental monitoring, so the observation random data are highly correlated in space. This paper proposed a WSN data correlation model named OD Model based on spatial location according to the most universal mode of omnidirectional Boolean sensing. Both analysis and simulation results show that the accuracy estimation of OD Model...
Hyperspectral radiance spectra are the sensor's response, through its spectral response functions (SRFs), to the at-sensor radiance field. As the SRFs vary with sensors, hyperspectral radiance data need to be transformed for cross-calibration with another sensor or data simulation of a future sensor. In fact, the hyperspectral radiance data are composed of average radiance in the sensor's passbands...
In the transaction process, the effective negotiation may cause more profits. In B2C and C2C, sellers only can use the fixed price or auction because they have no time and energy to bargain with buyers who are random on time and quantity, which reduces the benefits and successful transaction rate. This article established a negotiation model to solve this problem. This model conforms to the general...
