In this paper, we propose a light version (LV) algorithm that can recognize iris images in smartphones. The contribution is threefold. Firstly, we modified and re-designed the iris recognition algorithm that is capable of working in smartphone environment. Secondly, the modified algorithm is then extended in such a way that the best optimized solution can be found for authentication or verification...
While teleoperation provides a possibility for a robot to operate at extreme conditions instead of a human, teleoperating a robot still demands a heavy mental workload from a human operator. Learning from demonstrations can reduce the human operator's burden by learning repetitive teleoperation tasks. However, one of challenging issues is that demonstrations via teleoperation are less consistent compared...
Massive multiple-input multiple-output (MIMO) techniques are being considered for the fifth generation (5G) mobile communication systems in order to deliver high multiplexing gain. However, hardware impairments like quadrature imbalance in mixers violate the requirement for channel reciprocity and may change, e.g., with temperature or while aging. In addition, advanced wireless localization techniques...
The biochemical assays in a microfluidic centrifugal method uses specially designed disks for the miniaturization of typical laboratory processes. This paper describes the development of a low-cost and portable point-of-care device capable of performing blood tests based on microfluidic disk. The device is capable of performing blood cholesterol test in its automatic mode. In manual mode other test...
In this paper, acoustic wave propagation in water-saturated sand under controlled laboratory conditions is investigated. Our method uses a combination of two fundamental frequencies f1 & f2 generated using piezoelectric transducers placed on the surface of the sand, simulating seabed with fresh water and sand. The interaction of sound (acoustic) waves in a dispersive but homogenous medium will...
The fundamental parameters of a small monopole antenna were examined and how they are affected if high permittivity dielectric material is introduced to the structure, achieving a more compact and miniaturized antenna for mobile phone applications was also a part of the goal. The dielectric loading to the monopole patch antenna perturbed the fields within the patch as well as changes its permittivity,...
