LEDs can transport the signal or data via visible light instead of radio wave in some place that the radio wave will effect the human or damage the component. Therefore, this paper presents about the digital modulation for improving not only data rate and bit error rate but also flickering, colour rendering, dimming range, luminous efficacy rate that are required to keep in a satisfactory level. There are many types of the modulation that have different property. Therefore, the literature review is discussed and shows the comparison of Return-to-zero On-Off Keying (RZ-OOK), Non-Return-to-zero On-Off Keying (NRZOOK), and Binary Phase Shifted Keying (BPSK) in the form of analytical and simulation by the graph of BER versus SNR and also the comparative table of On-Off Keying (OOK), Colour Shifted Keying (CSK), Pulse Position Modulation (PPM), Pulse Width Modulation (PWM), and Orthogonal Frequency Division Multiplexing (OFDM).

In this paper, fractional derivative and the Liu's method are employed to obtain optical solitons, in nano-fibers, for perturbed nonlinear Schrödinger's equation with conformable fractional temporal evolution. These perturbation terms are all of Hamiltonian type and come with full nonlinearity. Several constraint conditions naturally fall out from the results obtained. © Copyright 2016 American Scientific Publishers All rights reserved.

This paper applies extended trial function method to extract bright and singular optical solitons to cascaded system that is a special case in birefringent fibers, where self-phase modulation of the first component is neglected. There are constraint conditions that guarantee the existence of such solitons. © Copyright 2016 American Scientific Publishers All rights reserved.

IoT Use Cases in Healthcare and Tourism

IoT Use Cases in Healthcare and Tourism

Healthcare and tourism are among the fastest growing business domains in the world. These are biggest service industries that affect whole world population and give jobs to millions of people. Recently we witness major changes in both industries, as more services are transferred to small providers, including individual entrepreneurs and SMEs. This process is driven by huge growth in demand, which cannot be fulfilled by applying traditional solutions. The new generation of digital services reshapes landscape of both industries. Some players see it as a threat, as digital services replace their traditional business models. But fighting against progress is useless, especially when you cannot fulfill growing by old means. Internet of Things (IoT) is an integral part of the Future Internet ecosystem that will have major impact on development of healthcare and e-Tourism services. IoT provides an infrastructure to uniquely identify and link physical objects to their virtual representations in Internet. As a result any physical object can have virtual reflection in the service space. This gives an opportunity to replace actions on physical objects by operations on their virtual reflections, which can be done much faster, cheaper and more comfortable for people. This provides a huge space for developing and applying new business models. In this paper we summarize research and development results of IoT studies and discuss ideas on how to apply them to business.

The ultimate goal of multiferroic research is the development of new-generation non-volatile memory devices1, the so-called magnetoelectric (ME) memories, where magnetic bits are controlled via electric fields without the application of electrical currents subject to dissipation. This low-power operation exploits the entanglement of the magnetization and the electric polarization coexisting in multiferroic materials2,3. Here we demonstrate the optical readout of ME memory states in the antiferromagnetic (AFM) and antiferroelectric (AFE) LiCoPO4, based on the strong absorption difference of THz radiation between its two types of ME domains. This unusual contrast is attributed to the dynamic ME effect of the spin-wave excitations, as confirmed by our microscopic model, which also captures the characteristics of the observed static ME effect. Our proof-of-principle study, demonstrating the control and the optical readout of ME domains in LiCoPO4, lays down the foundation for future ME memory devices based on antiferroelectric-antiferromagnetic insulators.

One of the crucial features of a service robot is the ability “to see” the environment and a target object for smooth navigation. This paper deals with a mobile robot that recognizes and tracks a moving object attached to a wheelchair in a obstacle existing environment. The experiment was conducted in three scenarios, the first one is that the robot is set to recognize and track a moving object in obstacle free environment, and the second and the third ones are the L-course and the crank course bordered by boxes as the obstacles. The third scenario was conducted five times with five different human-targets. The experimental results show that the proposed method is effective in recognizing and tracking the moving object.

In this paper, the results of previous research on the beat frequency filter for the LFM-CW Radar is applied for the realization of GNU software into radio and applied on the USRP. The beat frequency components for distances of 10 km, 50 km and 70 km respectively were found around the frequencies of 66 kHz, 330 kHz, and 460 kHz. By using MATLAB simulation, the computed results are 66.67 kHz, 333.33 kHz, and 466.67 kHz. As it occurs in the observation of the targets, frequency components obtained from the frequency spectrum can be divided into two parts, namely, the negative frequency components and the positive frequency components, where one component of this frequency is a reflection of the other frequency components. Therefore, the negative frequency components can be ignored. By observing at the positive frequency components, our experiment shows that the frequency spectrum shape of the output of the WX GUI FFT block is already similar with the simulation results by using the MATLAB®.

Growth mechanism of Co:TiO2 thin film deposited by metal organic chemical vapor deposition technique

引用

IOP Conference Series: Materials Science and engineering 2016年第1期128卷

作者： A Saripudin P Arifin Study Program of Electrical Engineering Dept. of Electrical Engineering Education Faculty of Technology and Vocational Universitas Pendidikan Indonesia Jl. Dr. Setiabudi 207 Bandung 40154 West Java Indonesia Physics of Electronics Material Lab. Study Program of Physics Faculty of Mathematics and Natural Science Institut Teknologi Bandung Jl. Ganeca 10 Bandung 40132 West Java Indonesia

In this research, we investigated the growth mechanism of cobalt-doped titanium dioxide (Co:TiO2) films. Thi Co:TiO2 thin films were grown on the n-type silicon substrate. The films were grown by metal organic chemical vapor deposition method. The growth temperature was varied of 325°C – 450°C. The films were characterized by SEM. Using Arheniu's equation, it is known that the activation energy value of film growth is positive in the range of temperature of 325°C – 400°C and negative in the range of temperature of 400°C – 450°C. These results show that the decomposition rate in the range of temperature of 325°C – 400°C is due to diffusion phase of precursor gas. On the other hand, the decomposition rate decreased in the range of temperature of 400°C – 450°C because the precursor gas decreased, and the surface chemical reaction was high.
