A Mobile Channel Model for VLC and Application to Adaptive System Design
(IEEE-INST Electrical Electronics Engineers Inc, 2017)
In this letter we propose a realistic channel model for visible light communication (VLC) assuming a mobile user. Based on non-sequential ray tracing we first obtain channel impulse responses for each point over the user ...
Turkey and the changing energy geopolitics of Eurasia
(Elsevier Science, 2019)
While Turkeys geographical location is usually viewed as a major advantage in the energy sphere since many countries in its immediate neighbourhood require active Turkish collaboration in order to export or import oil and ...
Broadband Matching via Unequal Length Cascaded Transmission Lines
(World Scientific Publ Co Pte Ltd, 2017)
In this paper a new approach based on the real frequency technique (RFT) has been proposed to solve broadband matching problems using cascaded unequal length transmission lines. At the end of the design process optimum ...

Augmentation mentoplasty using a custom-design wire cage
(Lippincott Williams & Wilkins, 2003)
Mentoplasty is often a complimentary procedure to rhinoplasty. At least 25% of all rhinoplasty patients may need a chin implant to balance facial features better. Augmentation mentoplasty using alloplastic implants such ...
A new technique for abdominal heart transplantation in rats
(Edizioni Minerva Medica, 2003)
Experimental studies in animals play a major role in the progress of medicine. Different surgical techniques have been described for heterotopic heart transplantation in rats. in this study we introduce a new technique for ...
Cognitive impairment in amyotrophic lateral sclerosis: evidence from neuropsychological investigation and event-related potentials
(Elsevier Science Bv, 2002)
The presence of subclinical cognitive impairment in patients with amyotrophic lateral sclerosis (ALS) is investigated using neuropsychological assessment and event-related potential recordings (ERP). An extensive battery ...
