Opportunistic spectrum sharing in relay-assisted cognitive systems with imperfect CSI
(
IEEE
, 2014 , Article)
In this paper, we consider spectrum sharing between cognitive radio (CR) users and a licensed primary user (PU) to enhance the spectrum efficiency. In the considered scenario, the PU is not able to successfully transmit ...
The limit of blockchains: Infeasibility of a smart obama-trump contract
(
Association for Computing Machinery
, 2019 , Article)
Although smart contracts are Turing complete, it is a misconception that they can fulfill all routine contracts.
PS/TiO2 (polystyrene/titanium dioxide) composite nanofibers with higher surface-to-volume ratio prepared by electrospinning: Morphology and thermal properties
(
John Wiley & Sons, Ltd.
, 2013 , Article)
Polystyrene (PS)/Titanium dioxide (TiO2) composite nanofibers were prepared by electrospinning of PS/TiO2 solution in N,N-dimethylformamide (DMF). The effect of PS and TiO2 concentration on the morphology and thermal ...
A dynamic MOPSO algorithm for multiobjective optimal design of hybrid renewable energy systems
(
John Wiley and Sons Ltd
, 2014 , Article)
In this paper, a dynamic multiobjective particle swarm optimization (DMOPSO) method is presented for the optimal design of hybrid renewable energy systems (HRESs). The main goal of the design is to minimize simultaneously ...
Software project management: Theory of constraints, risk management, and performance evaluation
(
Mundo Press
, 2014 , Article)
Constraints and risks are two critical factors that affect software project performance; more attention needs to be paid to constraints and risks in order to improve performance. In this paper, investigation will take place ...
A new compact formulation for the daily crew pairing problem
(
INFORMS Inst.for Operations Res.and the Management Sciences
, 2019 , Article)
The daily crew pairing problem (DCPP) seeks to generate a set of minimal-cost pairings that covers all the planned daily flights while complying with a variety of labor regulations, safety rules, and policies of the airline. ...
How to govern the non-cooperative amateur drones?
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In recent years, amateur UAVs have become more and more popular. This is due to the decreasing cost and growing range of applications such as weather monitoring, cargo transport and recreational purposes. However, ...
Cross Layer NOMA Interference Mitigation for Femtocell Users in 5G Environment
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this paper, we propose a joint channel allocation and power control algorithm by using cognitive radio non-orthogonal multiple access (CR-NOMA) for femtocell users (FUs). The aim is to maximize the sum rate of the FUs ...
A preemptive bound for the Resource Constrained Project Scheduling Problem
(
Springer US
, 2014 , Article)
The Resource Constrained Project Scheduling Problem is one of the most intensively investigated scheduling problems. It requires scheduling a set of interrelated activities, while considering precedence relationships, and ...
An adaptive step-down procedure for fault variable identification
(
Taylor & Francis
, 2015 , Article)
In a process with a large number of process variables (high-dimensional process), identifying which variables cause an out-of-control signal is a challenging issue for quality engineers. In this paper, we propose an adaptive ...
