Reliable listen-before-talk mechanism for medical implant communication systems
(Institute of Electrical and Electronics Engineers Inc., 2016)
Health care applications of wireless communication have been finding places dramatically. One of these applications is communication of implantable medical devices (IMD)s. It is expected that the number of IMDs will increase ...
Compensation for the mutual coupling in transmitting antenna arrays
(Institute of Electrical and Electronics Engineers Inc., 2016)
A numerical study is presented for the compensation of mutual coupling in antenna arrays. A Matlab code based on method of moments is used to find the compensated far field radiation patterns for non-identical and/or ...
Microwave heating of heavy oil and bitumen
(Institute of Electrical and Electronics Engineers Inc., 2016)
A theoretical study is presented for the feasibility of a microwave heating device that will raise the temperature of heavy oil and bitumen reservoir. The device is enclosed in a radome which is surrounded by a perforated ...
Controlled inter-carrier interference for physical layer security in OFDM systems
(Institute of Electrical and Electronics Engineers Inc., 2016)
Performance of OFDM is known to be very sensitive to frequency synchronization errors. By exploiting this feature, a novel technique is proposed to provide secure communication against eavesdropping. The technique is based ...
On reducing multiband spectrum sensing duration for cognitive radio networks
(Institute of Electrical and Electronics Engineers Inc., 2016)
In this work, the total spectrum sensing duration required for cognitive radios in multiband environments is studied to minimize the reactive handoff latency. Two spectrum sensing strategies, namely window-based and ...
Zero tail filter bank spread OFDM
(Institute of Electrical and Electronics Engineers Inc., 2016)
Waveforms proposed for future communication systems aim at fulfilling the demanding requirements of the next generation of 5G applications. In this paper, an enhancement over Zero Tail Discrete Fourier Transform Spread ...
Enhancing physical-layer security in wireless communications using signal space diversity
(Institute of Electrical and Electronics Engineers Inc., 2016)
In this paper, we enhance the security of OFDM systems in frequency selective fading channels using signal space diversity. In rich multipath environments, spatially separated channels are independent to each other. Hence, ...
Evaluation of biodegradable fixation system for mandibular angulus fracture by using finite element method
(Polish Academy of Sciences, 2016)
To date many fixation techniques of mandibular angle fractures have been introduced. There exist much research on the stability of plate and screws systems used in Champy technique in fixation of mandibular fractures. ...
Nurses' knowledge levels of chest drain management: A descriptive study
(AVES, 2016)
Objective: The physician is responsible for inserting one or more chest tubes into the pleural space or the mediastinal space and connecting them to an appropriate drainage system. When the general principles about care ...
Severe hyoglycemic attacks and remission of type 2 diabetes and psoriasis due to acitretin
(Modestum Ltd, 2016)
An 59 year old women with type two diabetes and psoriasis admitted with severe hypoglycemic attacks. Acitretin use was identified as the cause of this attacks. Two years after cessation of acitretin, she is still in remission ...
