Intellectual property (IP) core-to-node mapping is an important but intractable optimization problem in Network-on-Chip (NoC) application design. In this paper, we present an approach to map cores onto hierarchical NoC architecture which consists of two levels. The top-level interconnection network is realized by a 2D mesh of communicating routers, and a tree based topology is used at the secon...

The accuracy performance of fringe projection profilometry (FPP) depends on accurate phase-to-height (PTH) mapping and system calibration. The existing PTH mapping is derived based on the condition that the plane formed by axes of camera and projector is perpendicular to the reference plane, and measurement error occurs when the condition is not met. In this paper, a new geometric model for FPP...

Background Cardiac involvement is a major risk factor for sudden death in patients with systemic sarcoidosis. Pathologically, cardiac sarcoid lesions can be classified as early (mainly lymphocytic, similar to lymphocytic myocarditis), intermediate (active granulomatous), and late phase (primarily scar). These pathological processes can affect the myocardial extracellular space volume (ECV) in c...

The mobile Worldwide Interoperability for Microwave Access (Mobile WiMAX) air interface adopts orthogonal frequency division multiple access (OFDMA) as multiple access technique for its uplink (UL) and downlink (DL) to improve the multipath performance. All OFDMA based networks including mobile WiMAX experience the problem of high peak-toaverage power ratio (PAPR). The literature is replete wit...

introduction: several radiotracers are being used for sentinel node mapping in patients with breast cancer. in the current study, we reported our experience with 99m-tc phytate for sentinel node mapping in mashhad university of medical sciences. methods: all breast cancer patients who underwent sentinel node mapping using 99m-tc phytate were included. all patients received intradermal peri-areo...

Deviating from the conventional Hidden Markov ModelMulti-Layer Perceptron (HMM-MLP) hybrid paradigm of using MLP for classi cation, the proposed discriminative MLP technique uses MLP as a mapping module for feature extraction for conventional HMM-based systems. The MLP is discriminatively trained on the phonetically labeled training data to generate the phoneme posterior probabilities. We achie...

This paper presents a robust phase correlation based sub-pixel feature matching technique and its application in motion flow estimation, pixel-to-pixel image-co-registration and DEM generation. We propose to use a phase fringe filter and a highly robust technique in the direct Fourier-based phase correlation algorithm for translational shift estimation in sub-pixel accuracy. Noting the problem ...

INTRODUCTION: Sodium MRI shows promise in assessing cartilage health [1], characterizing tumors [2], detecting abnormal sodium levels in the kidneys [3], and assessing tissue damage following stroke [4]. However, relatively low Na concentrations in biological tissues, a rapid biexponential signal decay, and a low gyromagnetic ratio make sodium MRI challenging. Recent improvements in MRI hardwar...

OBJECTIVE Intraoperative localisation of the sensorimotor cortex using the phase reversal of somatosensory evoked potentials (SEPs) is an essential tool for surgery in and around the perirolandic gyri, but unsuccessful and perplexing results have been reported. This study examines the effect of tumour masses on the waveform characteristics and feasibility of SEP compared with functional neurona...
