An Automated Dynamic Offset for Network Selection in Heterogeneous Networks Abstract?Complementing traditional cellular networks with the option of integrated small cells and WiFi access points can be used to further boost the overall traffic capacity and service level. Small cells along with WiFi access points are projected to carry over 60 percent of all theglobal…
An Efficient and Clinical-Oriented 3D Liver Segmentation Method Abstract-By segmenting, modeling, and visualizing computed tomography sequence data, surgeons can better understand the spatial relationship of the intrahepatic vein, portal vein, artery, and tumor. Accurate preoperative understanding of liver anatomy and volume of the corresponding liver segment are necessary for anatomical liver resection. This paper gives…
An Efficient and Fine-grained Big Data Access Control Scheme with Privacy-preserving Policy Abstract? How to control the access of the huge amount of big data becomes a very challenging issue, especially when big data are stored in the cloud. Ciphertext-Policy Attribute-based Encryption (CP-ABE) is a promising encryption technique that enables end-users to encrypt their data…

An efficient andsecurecipherschemeforimages confidentiality preservation Abstract? A Novel image encryption scheme based on two rounds of substitution-diffusion is proposed. Two main objectives have guided the design of this scheme: (a) robustness against the most know type of attacks (stastical, chosedn/know plain-text, chiphertext (i.e., execution time reduction) in order in to meet recent mobiles? applications? requirements….
An Efficient Bayesian PAPR Reduction Method for OFDM-Based Massive MIMO Systems Abstract? The problem of peak-to-average power ratio (PAPR) reduction in orthogonal frequency-division multiplexing (OFDM) based massive multiple-input multiple-output (MIMO) downlink systems. Specifically, given a set of symbol vectors to be transmitted to K users, the problem is to find an OFDM-modulated signal that has…
An Efficient File Hierarchy Attribute-Based Encryption Scheme in Cloud Computing Abstract? Ciphertext-policy attribute-based encryption (CP-ABE) has been a preferred encryption technology to solve the challenging problem of secure data sharing in cloud computing. The shared data files generally have the characteristic of multilevel hierarchy, particularly in the area of healthcare and the military. However, the…

An Efficient Hybrid-Switched Network-on-Chip for Chip Multiprocessors Abstract? Chip multiprocessors (CMPs) re quire a low-latency interconnect fabric network-on-chip (NoC) to minimize processor stall time on instruction and data accesses that are serviced by the last-level cache (LLC). While pack et-switched mesh interconnects sacrifice performance of many-core processors due to NoC- induced delays, existing circuit-switched interconnects…
An Efficient Image Processing Based Method for Gills Segmentation from a Digital Fish Image Abstract?Abstract The quality and freshness of a fish sample is mainly affected due to the handling and storage conditions during the post harvesting period. The retention time and storage medium are the two main factors affecting the fish quality. This paper…
An efficient multi-channel MAC protocol for wireless adhoc networks Abstract? IEEE 802.11 MACis designed for single channel and based on Carrier Sense Multiple Ac-cess with Collision Avoidance (CSMA/CA). The throughput of network is limited by the Bandwidth of the single channel and the CSMA-based MAC protocol with omni directional antennas can cause the serious unfairness…
