This paper proposes QR-based criteria for efficient selection of multi-mode precoders in multi-user multiple-input multiple-output (MU-MIMO) precoded systems with a limited feedback. In particular, a MU-MIMO QR based precoding scheme is developed which takes advantage of the overall precoder design among users in conjunction with QR detection. A selection criterion is developed to identify the ...

In this paper, we propose a novel representation of the FMLLR transform. This is different from the standard FMLLR in that the linear transform (LT) is expressed in a factorized form such that each of the factors involves only one parameter. The representation is mainly motivated by QR-decomposition of a square matrix and hence is referred to as QR-FMLLR. The mathematical expressions and steps ...

The desire to share and reuse knowledge has led to the establishment of a new knowledge representation language: the Web Ontology Language (OWL). The design choices made in OWL are properly documented, but their implications for AI research are not yet clear. This thesis explores the expressiveness of OWL by formalising the vocabulary and models used in qualitative reasoning (QR), and the appli...

Objective(s): Response surface methodology (RSM) by central composite design (CCD) was applied to statistically optimize the preparation of Rutin-Quercetin (Ru-Qr) dual drug loaded human hair keratin nanoparticles as well as evaluate the characteristics. Materials and Methods: The effects of three independent parameters, namely, temperature (X1:10-40 C), surfactant (X2: SDS (1), SLS (2), Tween-...

  Background: Quercetin is a strong antioxidant and long-term treatment of STZ-diabetic animals and it has been shown to reduce oxidative stress.   Objective: Antioxidants have essential effect on spermatogenesis and sperm parameters. Enhanced oxidative stress and changes in antioxidant capacity are considered to play an important role in the pathogenesis of chronic diabetes mellitus.   Methods...

The QR algorithm is an algorithm for computing the spectral decomposition of a symmetric matrix [9]. Despite it’s high accuracy, other methods are often preferred for the symmetric eigenvalue problem due to the QR algorithm’s relatively poor performance [13]. In recent years, new techniques have arisen that dramatically improve its performance. The restructured symmetric QR algorithm, introduce...

Quick Response Code (QR Code) has become an important entrance of O2O (Online to Offline) in the era of mobile internet. Many applications, such as transformation of URLs, the descriptions of these images, and so on can be realized through embedding QR Code into images. However, the embedding of QR Code may destroy some image details in the corresponding area, which is annoying, especially in t...

The QR algorithm computes the Schur form of a matrix and is by far the most popular approach for solving dense nonsymmetric eigenvalue problems. Multishift and aggressive early deflation (AED) techniques have led to significantly more efficient sequential implementations of the QR algorithm during the last decade. More recently, these techniques have been incorporated in a novel parallel QR alg...

Barcode is a representation of information which is non human readable. Barcode can be characterized into two categories 1-dimensional barcode and 2-dimensional barcode. Quick Response (QR) code is popular type of two dimensional barcode. Information stored in QR code is in the form of white and black dots. The stored information is related to the product to which it is attached. This informati...
