This paper proposes an algorithm to reconstruct a High Resolution (HR) image from a set of blurred, warped, undersampled, and noisy measured images. The proposed algorithm uses the affine block-based algorithm in the maximum likelihood (ML) estimator. It is tested using synthetic images, where the reconstructed image can be compared with its original. A number of experiments were performed with

Spectrum sensing is one of the most challenging tasks required of a cognitive radio receiver. In this paper, we consider the first stage of spectrum sensing, where it is required to perform the sensing as fast as possible and with an acceptable performance under different channel conditions. The target signal to be sensed is a Long Term Evolution (LTE) signal. We first propose sensing the whole

Contractor selection is carried out in order to choose a competent and capable contractor to do the work. To help in this selection, baselines are established to ensure that the contractors have the required skills, resources, and abilities to execute the project. Contractor selection is a multiple criteria decision making wherein several criteria are required to be evaluated simultaneously. This

In this paper, we investigate the benefits of using cooperative relays in interweave (opportunistic) cognitive radio systems. A novel distributed space frequency (DSF) code for relay cooperation is presented. The code is designed to be a multi-user multi-OFDM channels code. It achieves a cooperative diversity gain of order NL for all users, where N is the number of relays and L is the number of

According to the International Technology Roadmap for Semiconductors (ITRS), the traditional scaling will no longer meet the performance and integration requirements of systems-on-chip (SoC) in the long term. Therefore, new I/O and packaging paradigms are needed. Three-dimensional integration is a promising alternative option to traditional 2D planar chips. 3D integration is mainly restricted by

SplitPro is a tool that processes the code of large SystemC modules and splits them into two or more smaller ones without affecting functionality. The purpose of this process splitting is to overcome some inherent inefficiencies of the SystemC 2.1 scheduler, such as unnecessary process wake-up calls, and unnecessary evaluation of portions of code that do not change the output of the system at the

Case studies provide the basis for empirical grounding of management theory or management principles. But there needs to be a systematic methodology for constructing case histories so that theory and principles can be compared to case reality. I propose such a methodology and illustrate the use of the methodology in two famous business cases - the origin of Cisco Systems and the bankruptcy of

Objectives This study evaluated the value of systolic and diastolic deformation indexes determined by strain-encoded imaging to predict persistent severe dysfunction at follow-up in patients after reperfused acute myocardial infarction (AMI) in comparison with late gadolinium enhancement (LGE). Background Animal studies suggest that regional diastolic function provides information about myocardial

Background: Cardiac allograft vasculopathy (CAV) progressively compromises microvascular perfusion and function in heart transplantation (HTx)-recipients. The aim of our study was to investigate the ability of quantitative myocardial blush grade (MBG) to detect CAV. Methods: In consecutive HTx-recipients (n = 72) who underwent surveillance cardiac catheterization, MBG was assessed visually and
