We propose a flexible multi-frequency channel correlator upgrade for MUSER-I array. The upgrade correlator has a more flexible architecture to be extensible for signal receiving elements. It can process 1024 frequency channels in IF band and the correlation sensibility is improved by utilizing 4-bit quantization in pre-correlation as well. The enhanced multi-frequency channel processing capability...
Surveillance cameras have been widely used in different scenes. Accordingly, a demanding need is to recognize a person under different cameras, which is called person re-identification. This topic has gained increasing interests in computer vision recently. However, less attention has been paid to video-based approaches, compared with image-based ones. Two steps are usually involved in previous approaches,...
Reservoir computing has been widely applied in dynamical system modeling and solving time-dependent problems at low computational expense. However, when confronting some complex tasks that exhibit multiple sets of dynamics, the conventional reservoir computing model with a single reservoir may become ineffective and powerless. Inspired by the modality-independent but functionally connected brain regions,...
Transparent computing is an implementation of ubiquitous computing that is aimed at providing active services for users. In transparent computing, the execution (computation) of computer instructions and data is temporally and spatially separated from their storage. Cloud computing solves the issue of data cloudlization, while transparent computing solves the one of software cloudlization. This paper...
The recursive filter (IIR) parallel programming on SIMD is more difficult than that of nonrecursive algorithms due to data dependency. Several transformation methods for parallel coding of IIR filter on SIMD have already been proposed to deal with data dependency. However, the inherent prologue and epilogue in these methods obviously increase the complexity of control structures and induce extra hardware...
We propose a new virtualized Peer-to-Peer (P2P) core-network architecture where each user gets its own private copy of the core network. This enables higher security and novel services, that cannot be deployed in today's architecture. We describe the new architecture in detail, presenting some of its many advantages and novel services. Lastly, we discuss some architectural options and their tradeoff...
This paper proposes a novel method named ScholarRank to evaluate the scientific impact of rising stars. Our proposed ScholarRank integrates the merits of both statistical indicators and influence calculation algorithms in heterogeneous academic networks. The ScholarRank method considers three factors, which are the citation counts of authors, the mutual influence among coauthors and the mutual reinforce...
Network function virtualization (NFV) enabled software defined optical transport networks are first designed to implement the virtualization of control and node function, and virtualization solution is demonstrated to verify the overall feasibility and efficiency.
For the first time, re-provisioning is introduced into advanced reservation enabled optical transport networks as a novel perspective for optimization. Demonstration results show parallel service re-provisioning (PSRP) can improve the efficiency of network resource significantly.
More and more cloud services emerging because of increased demand, but there is significant room for improvement. We propose architecture to integrate public cloud services for reducing costs. We consider three issues: (1) The general cloud storage services are unsuitable for large and complex data. A NoSQL datastore, the most common type of database for big data, can process operational information...
The rise of cloud computing and the Internet not only bring change on the data center, but also lead to transformation in software development, deployment, operation and maintenance. With the continuous improvement of the current cloud computing and the internet environment, how to make better use of cloud computing platform, and how to serve the users is a popular field of computer software is a...
Human action can be decomposed into a series of temporally correlated motions. Since the traditional bag-of-words framework based on local features cannot model global motion evolution of actions, models like Recurrent Neural Network (RNN) [15] and VideoDarwin [5] are accordingly explored to capture video-wise temporal information. Inspired by VideoDarwin, in this paper, we present a novel hierarchical...
After investigating the data processing characteristics of several scientific applications in various disciplines from bioinformatics to geology, we discover that they share one common feature: raw data is written once onto a storage system and then it is read into memory once for analyzing, after which it will seldom be used in the future. Typically, these scientific applications are running on a...
A high performance table-based architecture implementation for CRC (cyclic redundancy check) algorithms is proposed. The architecture is designed based on a highly parallel CRC algorithm. The algorithm first divides a given message with any length into bytes. Then it performs CRC computation using lookup tables among the divided bytes in parallel. At last, the results are XORed to obtain the CRC value...
We present a cloud resources integrated provisioning architecture utilizing coordinated virtualization of distributed datacenters and operator's multi-domain software define optical network. The overall feasibility and efficiency of two proposed virtual network composition schemes are investigated on our testbed.
Modular multiplication is the most crucial component in RSA cryptosystem. In this paper, we present a new modular multiplication architecture using the Strassen multiplication algorithm and Montgomery reduction. The architecture is different from the interleaved version of Montgomery multiplication traditionally used in RSA design. By selecting different bases of 16 or 24 bits, it could perform 8,192-bit...
This paper presents an FPGA co-processor design for adaptive lane departure warning system, which requires intensive computation for real-time video image processing. The main functions of the co-processor include color scheme conversion, 2D filtering, transferring intensity into binary pattern using Otsu's threshold method, and detecting lanes using Hough transform. The system design is implemented...
The first plausible scheme of fully homomorphic encryption (FHE), introduced by Gentry in 2009, was considered a major breakthrough in the field of information security. FHE allows the evaluation of arbitrary functions directly on encrypted data on untrusted servers. However, previous implementations of FHE on general-purpose processors had very long latency, which makes it impractical for cloud computing...
The vision of Self-Organizing Networks (SON) has been drawing considerable attention as a major axis for the development of future networks. As an essential functionality in SON, cell outage detection is developed to autonomously detect macrocells or femtocells that are inoperative and unable to provide service. Previous cell outage detection approaches have mainly focused on macrocells while the...
ITRI container computer is a modular computer designed to be a building block for constructing cloud-scale data centers. Rather than using a traditional data center network architecture, which is typically based on a combination of Layer 2 switches and Layer 3 routers, ITRI containercomputer's internal interconnection fabric, called Peregrine, is specially architected to meet the scalability, fast...
