BACKGROUND In order to determine myocardial salvage, accurate quantification of myocardium at risk (MaR) is necessary. We present a validated novel automatic segmentation algorithm for quantification of MaR by myocardial perfusion SPECT (MPS) in patients with acute coronary occlusion. METHODS AND RESULTS Twenty-nine patients with coronary occlusion were injected with a perfusion tracer before...

A Mobile Ad-Hoc Network(MANET) is a structure-less network where the mobile nodes randomly moved in any direction within the transmission range of the network. Due to this mobility, wide range of intrusion occurs in MANET. Therefore, Intrusion Detection Systems (IDS) are significant in MANETs to identify the malicious behavior. In order to improve the secured data communication an efficient Qua...

Filling a gap in nonconvex quadratic programming, this paper shows that the global resolution of a feasible quadratic program (QP), which is not known a priori to be bounded or unbounded below, can be accomplished in finite time by solving a linear program with linear complementarity constraints, i.e., an LPCC. Alternatively, this task can be divided into two LPCCs: the first confirms whether t...

Keywords: Network convergence Multimedia services Quality of service The emerging use of real-time 3D-based multimedia applications imposes strict quality of service (QpS) requirements on both access and core networks. These requirements and their impact to provide end-to-end 3D videoconferencing services have been studied within the Spanish-funded VISION project, where different scenarios were...

NVMe-over-Fabrics (NVMeoF) is expected to have high-performance and be highly scalable for disaggregating NVMe SSDs High-Speed Network (HSN)-attached storage servers, thus the aggregated in servers can elastically allocated remote host better utilization. However, due well-known connection scalability issue of RDMA NICs (RNICs), RDMA-enabled HSN only provide a limited scale performant Queue Pai...

In this paper, we propose an enhanced method of initializing the quantization parameter (QP) in H.264 rate control algorithm based on image quality balance of GOP (Group of Pictures) using support vector machines (SVMs). Primarily, we analyze characteristics of some typical video sequences by motion vectors. And then we choose four video sequences with different characteristics and computer the...

In this paper, we propose a method of initializing the quantization parameter (QP) in H.264 rate control algorithm based on spatial characteristic of conversational video. Primarily, we choose the fourteen various conversational videos and calculate the complexity of the macroblock (MB) using variance of MB. The spatial characteristic of each video can be quantized by the proportion of the numb...

Software security is a significant issue in the Internet age. In order to prevent software from piracy and unauthorized modification, many techniques have been developed. Software watermarking is such a technique that can be used to protect software by embedding some secret information into the software to identify its copyright owner. In this paper, we discuss algorithms of software watermarki...

We present a primal-dual active-set framework for solving large-scale convex quadratic optimization problems (QPs). In contrast to classical active-set methods, our framework allows for multiple simultaneous changes in the active-set estimate, which often leads to rapid identification of the optimal active-set regardless of the initial estimate. The iterates of our framework are the active-set ...
