Quantized Massive MU-MIMO-OFDM Uplink Abstract?Abstract Coarse quantization at the base station (BS) of a massive multi-user (MU) multiple-input multiple-output (MIMO) wireless system promises significant power and cost savings.Coarse quantization also enables significant reductions of the raw analog-to-digital converter data that must be transferred from a spatially separated antenna array to the baseband processing unit. The…
Quasi Y-Source Boost DC-DC Converter Abstract? Quasi Y-Source Boost DC-DC Converter. A new topology called ?quasi-Y-source dc-dc converter? is presented. It inherits all the advantages of the original Y-source converter. In addition, the new topology draws a continuous current from the source, which is definitely more appropriate for most renewable sources. It also has dc-current…
Quaternion-Michelson Descriptor for Color Image Classification Abstract? A simple yet powerful framework called quaternion-Michelson descriptor (QMD) to extract local features for color image classification. Unlike traditional local descriptors extracted directly from the original (raw) image space, QMD is derived from the Michelson contrast law and the quaternionic representation (QR) of color images. The Michelson contrast…
Query-Adaptive Image Search With Hash Codes Abstract?Scalable image search based on visual similarity has been an active topic of research in recent years. State-of-the-art solutions often use hashing methods to embed high-dimensional image features into Hamming space, where search can be performed in real-time based on Hamming distance of compact hash codes. Unlike traditional…
Optimal Joint Scheduling and Cloud Offloading for Mobile Applications Abstract? While there has been a significant amount of work on object search and image retrieval, the focus has primarily been on establishing effective models for the whole images, scenes, and objects occupying a large portion of an image. In this paper, we propose to leverage…
Quey based aggreculture details Abstract? Quey based aggreculture details. In this paper, we study row-based detailed placement refinement for triple patterning lithography (TPL), which asks to find a refined detailed placement solution as well as a valid TPL layout decomposition under the objective of minimizing the number of stitches and the half-perimeter wirelength. Our problem…
Quiz Application Abstract-With the vast development of various technologies, learning today is no longer confined to classrooms with lecture delivery as the only method of? onveying knowledge, rather, an electronic means of learning has continued to evolve. Electronic learning (e-Learning), which facilitates education using? communications networks, has made learning possible from anywhere at any time…
Quiz Management System Abstract?The system not only reflects the justification and objectivity of examination, but also releases the workload of teachers, which is accepted by more and more schools, certification organizations and training organizations. Most online examination systems only support several fixed question types and don’t allow users define their own question types, so they…
R3E: Reliable Reactive Routing Enhancement for Wireless Sensor Networks Abstract?Abstract Providing reliable and efficient communication under fading channels is one of the major technical challenges in wireless sensor networks (WSNs), especially in industrial WSNs (IWSNs) with dynamic and harsh environments. In this work,we present the Reliable Reactive Routing Enhancement (R3E) to increase the resilience to…
RAAC: Robust and Auditable Access Control With Multiple Attribute Authorities for Public Cloud Storage Abstract-Data access control is a challenging issue in public cloud storage systems. Ciphertext-policy attribute-based encryption (CP-ABE) has been adopted as a promising technique to provide flexible, fine-grained, and secure data access control for cloud storage with honest-but-curious cloud servers. However, in…

Radio Database Compression for Accurate Energy-Efficient Localization in Fingerprinting Systems Abstract? Location fingerprinting is a positioning method that exploits the already existing infrastructures such as cellular networks or WLANs. Regarding the recent demand for energy efficient networks and the emergence of issues like green networking, we propose a clustering technique to compress the radio database…
