In this paper we study the problem of estimating the cardinality of pairwise set operations (union and intersection) over sets possessed by different data owners, while preserving differential privacy. In our problem setting, a data owner could only communicate with an untrusted server, and thus have to perturb its set data for privacy protection before sharing them with the server. This problem setting...
Deep learning is used for learning better features through constructing a model of machine learning, which contains a lot of hidden layers. At present, deep learning is widely used in face recognition. But faces of different ages, facial expressions and other changes will affect the result of face recognition. The human ear is not affected by different ages, facial expressions, makeups and so on,...
With the growth of online business, many brick and mortar retailers, from department stores, warehouse retailors, to supermarkets have been developing their web-based channels. However, how retailors deploying numerous varieties of products in the two different channels demands management consideration. This research is designed to examine the effects of product categories on consumer perceptions...
Robot warehouse automation has attracted significant interest in recent years, perhaps most visibly in the Amazon Picking Challenge (APC) [1]. A fully autonomous warehouse pick-and-place system requires robust vision that reliably recognizes and locates objects amid cluttered environments, self-occlusions, sensor noise, and a large variety of objects. In this paper we present an approach that leverages...
Rice Planthopper (RPH) infestation in paddy field is a serious disaster in Asia every year. Finding RPHs based on image processing is an important thing before RPHs growth. We propose a region of interest (ROI) method to detect RPHs clearly. First, get rectangle ROI in HSV space and do color analysis. By using decision tree algorithm, classify analytic data to get binary image of RPHs. The results...
Multi-disciplinary virtual prototype (MDVP) based on modeling and computer simulation technology has been applied in a wide range of engineering applications, especially the design, testing and evaluation of complex products. Generally, a large set of parameters need to be optimized to improve the performance of the prototype, which comprises a number of heterogeneous models from multiple domains...
With low power and variation-tolerant features, asynchronous have been widely used in advanced VLSI designs. Testing asynchronous circuits has become a very important practical issue. This research presents new test methodology, including design for testability (DFT) and automatic test pattern generation (ATPG), for asynchronous dual-rail circuits. The proposed DAC-scan cell is a hazard-free scan...
Layout pattern classification, which groups similar layout clips into clusters, underlies a variety of design for manufacturability (DFM) applications such as hotspot library generation, hierarchical data storage, and yield optimization speedup. The key challenges of layout pattern classification are clip representation and clip clustering, while the mutually conflicting concerns are efficiency and...
Having seamless Internet connection is highly desirable for wireless sensor network (WSN). IPv6 offers the most promising solution to deal with the large quantity of nodes or "things". This demonstration presents a versatile research and development (R&D) or prototyping platform, on which we implement generic hardware and software framework for sensing/monitoring as well as remote control...
In recent years, there has been considerable interest in Intercloud. Inspired by the Internet, Intercloud allows clouds to be interconnected, forming a cloud/network of clouds. With Intercloud, many new and powerful cloud computing services can be provided. One of the basic problems with supporting Intercloud is the need to address the issue of how to ensure that clouds can communicate with each other...
Getting seasonal flu vaccines and seeking medical treatments are two effective strategies to prevent the spread of seasonal influenza. However, less than half of Americans received flu vaccines in the 2014–2015 flu season. A high cost-sharing rate in healthcare insurance policies results in few patients to visit doctors, leading to slow recovery rate. In this paper, we design insurance policies, including...
The computational soundness of formal encryption is studied extensively following the work of Abadi and Rogaway[1]. Recent work considers the scenario in which secret sharing is needed, and separately, the scenario when key cycles are present. The novel technique is the use of a co-induction definition of the adversarial knowledge. In this paper, we prove a computational soundness theorem of formal...
Due to the uncertainty and low forecast accuracy of the distributed generation output, the traditional voltage control method is facing big challenges. This paper presents a novel three-phase reactive power and voltage distributed control method of AC/DC hybrid active distribution network based on model predictive control. This method uses model predictive control theory to deal with uncertainty of...
Due to a large number of distributed generators and controllable devices approached to distribution network, the traditional optimization control method, which separates the transmission and the distribution system, is not applicable. This paper presented a voltage optimization method combining transmission and distribution networks. The method considered the differences between transmission network...
For distribution network with a large number of distributed generation, the output fluctuation of distributed power sources and load variation will cause voltage over-limit. Aiming at AC voltage control of AC/DC hybrid distribution network, this paper proposes the hierarchical voltage control framework. Based on bus voltage level, we construct typical scenes while the voltage is normal, mild over-limit...
Pushing is a motion primitive useful to handle objects that are too large, too heavy, or too cluttered to be grasped. It is at the core of much of robotic manipulation, in particular when physical interaction is involved. It seems reasonable then to wish for robots to understand how pushed objects move.
Graphene is coupled with silicon quantum dots (Si QDs) on the top of bulk Si to form a hybrid photodetector. SiQDs cause the built-in potential of the graphene/Si Schottky junction to increase. Si QDs also significantly reduce the optical reflection of the photodetector. Both of the electrical and optical contributions of SiQDs enable the superior performance of the photodetector.
For knots spaced uniformly, the B-spline interpolation can be represented by an interpolator with a B-spline filter. In this paper, a B-spline filter bank is designed to describe the nonuniform B-spline interpolation. Signals considered here are those that can be split into several uniform subsequences by decimation. The decimated signals are then interpolated by the uniform B-spline functions to...
In this paper, a reconfiguration strategy for distribution network based on a power supply capacity index (PSCI) is proposed to tackle the security problems caused by the increasing number of electric vehicles (EVs) with spatial-temporal charging loads in active distribution network (ADN). Firstly, a spatial and temporal model is developed to obtain all the EV charging loads in the ADN along one scheduling...
A previous study shows that a low-density parity-check (LDPC) coded modulation scheme with an extremely sparse parity-check matrix and non-Gray mapping is able to achieve an error-rate performance compatible to that of a conventional Gray-mapping based scheme. This paper presents an associated iterative demodulation and decoding (IDD) receiver architecture that is targeted at flash memory applications...
