Heterogeneous networks (HetNets) employing massive multiple-input multiple-output (MIMO) and millimeter-wave (mmWave) technologies have emerged as a promising solution to enhance the network capacity and coverage of next-generation 5G cellular networks. However, the use of traditional fully-digital MIMO beamforming methods, which require one radio frequency (RF) chain per antenna element, is not practical for large-scale antenna arrays, due to the high cost and high power consumption.

In order to improve the energy capture efficiency of a multi-pendulum wave energy converter, a mathematical model of the pendulum structure has been built. The final structure parameters of the pendulum have been obtained by using genetic algorithm based on the numerical simulation results of the pendulum structure optimization.

This paper presents some results of fabrication and experiment of an electrical generator for sea wave energy. The electrical generator device is fixed on the bottom of the sea and works in the vertical direction of sea waves. The experiment results show that, for the received voltage and current, the power of the electrical generator is up to 300 W and operates stably at about 200 W during experiment at sea. The output voltage is at 220 VAC frequency 50 Hz and is a pure sine wave.

This paper proposes a control system connecting for the grid-connected PV (Photovoltaic) system. The control structure includes two alternating flyback converters, a control unit for connecting PV system to the grid, filter circuits at input and output of the converters. The output voltages of two flyback converters having half sinusoidal wave are is converted to completely sinusoidal wave by unfolding converter with the grid synchronization. This control system monitors the load demand and generated power capacity of PV in order to regulate power getting from the grid.

The objective of this book is to acquaint the reader with explosive driven pulsed power devices, theory and applications. This includes those devices that convert the chemical energy stored in high explosives into electrical energy and that use shock waves generated by the explosives to release the energy stored in ferromagnetic or ferroelectric materials in the form of electrical energy. The reader might well ask why one should use explosive driven pulsed power for any application, since it is inherently single shot in nature.

Sputum examination is a key diagnostic procedure for patients suspected of having pulmonary TB, including those for whom bronchoscopy is planned.1,2 In addition, early identification of persons with TB remains the most effective way of preventing TB transmission. However, some patients are unable to produce sputum for examination. In such cases, sputum induction by aerosol inhalation and/or gastric aspiration has been preferred.

The electromagnetic power is generated and radiated by antennas. Timevarying current radiates electromagnetic waves (radiated electromagnetic fields). Radiation pattern, beam width, directivity, and other major characteristics can be studied using Maxwell’s equations, see Section 2.2. We use the vectors of the electric field intensity E, electric flux density D, magnetic field intensity H, and magnetic flux density B. The constitutive equations are D = εE and B = µH where ε is the permittivity; µ is the permiability. It was shown in Section 2.
