Abstract

Here a novel binary power control scheme is presented with radio channel uncertainty which includes path loss, Rayleigh fading, shadowing coefficient, and interference from other users to analyse the performance of MIMO-OFDM wireless communication system. From bit error rate (BER) point of view a two tier system with adjacent interference is taken into account to guarantee QoS. The main objective of this system is to optimize energy efficiency with QoS. Taking both energy efficiency and quality of service (QoS) an energy efficient binary power control with BER constraint algorithm is presented. The performance of this system is analyzed and results of the same are presented to show the effectiveness of the system presented.

Abstract

Recent Technological advances in Wireless Communication has shown the convergence of terminals and networks that support multimedia and real-time applications. This obviously puts an immense pressure on battery of any mobile device. The CMOS has been the leading technology in today’s world of mobile communication due to its low power consumption. Reduction of leakage power in CMOS has been the research interest for the last couple of years. In CMOS integrated circuit design there is an important trade-off between technology scaling and static power consumption. In today’s CMOS technology the leakage power consumption plays a significant role. As we approaching to nano-scale design the total chip power consumption becomes dependent on leakage power. Increasing the battery life in mobile wireless communication and mobile computing and similar other applications is the topic of research now-a days... Further, since the leakage of battery exists even when devices are in idle state makes leakage power loss most critical in CMOS VLSI circuits. Many techniques have been evolved to tackle the problem and its still in progress. This paper mainly focuses on the review of various works done in this field till today’s date. Further a review of recent work done on a new technique LSSR (Lector Stack State Retention Technique) is discussed in the paper.

Abstract

A fractal is a recursively generated object having a fractional dimension. So many objects, including antennas, can be designed using this recursive nature of a fractal. In this paper we have used the fractal geometry arrangements for the design of planar antenna arrays with low side lobes. Iterated Function System (IFS) is used to generate the sierpinski fractal antenna arrays using circular shapes. CST Microwave Studio EM Simulation software is used for design & simulation of these antenna arrays. Two resonant frequencies like. 1936 GHz &. 222 GHz are achieved. Better performance parameters like return loss, VSWR, directivity, gain, bandwidth enhancement with low SLL are estimated.

Abstract

Are examined the laws of the self-induction of capacitance and inductance, which it is customary to assume as reactive elements. It is shown that with the connection to the sources of direct current and voltage they have the effective resistance, which depends on the time. Is examined the parametric self-induction of the elements indicated and it is shown that in the regime of parametric self-induction the capacitance and inductance can not only derive energy from the power sources, but also return it into the external circuits. The velocity of propagation of constant voltages and currents in the long lines is obtained. In this case the laws of parametric self-induction are used. This task cannot be solved, using standard wave equations for the long lines.

Abstract

The contact potential difference this is the potential difference, which appears between the located in the electrical contact conductors under the thermodynamic equilibrium conditions. As a result this between the conductors occurs the electron transfer until the Fermi levels in both conductors are made even. The established contact potential difference is equal to difference the work function of conductors, referred to the electron charge. In the article is described the new type of contact potential difference, which appears with the flow of the current through conductors. Contact the potential difference indicated depends on the strength of current, which flows through conductor; therefore it it is possible to name aelektrocurent contact potential difference. The results of investigating the electrification of the superconductive windings and tori during the introduction in them of direct currents are represented. Are proposed the schematics of magnetometers, which make it possible to measure the magnetic fields over a wide range of their values.

Abstract

Is shown that in the nonmagnetized plasma, besides longitudinal Langmuir resonance can exist the transverse plasma resonance. The resonance indicated can exist in the confined plasma. It is known that with the nuclear explosions the electromagnetic radiation in the very wide frequency band is observed, up to the radio-frequency range. And if the emission in field of light range can be explained by the emission of separate atoms, then emission in the region of radio-frequency band can be caused only by collective processes, which occur in the confined plasma. The use of transverse resonance makes it possible to create resonators and band-pass filters, and also lasers on the collective plasma oscillations. Transverse plasma resonance can be used also for the warming-up of plasma and its diagnostics. Is introduced the concept of magnetoelectrokinetic waves.

Abstract

In this paper, a digitally controlled single input multi output current-mode K.H.N. Biquad Filter is presented. The filter circuit is composed of three DVCCs together with four grounded resistors and two grounded capacitors. The digital control is incorporated using a current-summing network (CSN). Tuning of resonant frequency is carried out by 3–bit digital control word. Block by block replacement has been done to observe the change in the relationship between resonant frequency of the band-pass filter with the control word. The filter circuit showed three different variations when the DVCC blocks were replaced (one by one) with 3-bit DC-DVCC blocks. PSPICE simulations using TSMC 0.25 micron CMOS technology have been performed to validate the theoretical results.

Abstract

The Huygens principle says, that each element of wave front can be examined as the center of the second disturbance, which generates second spherical waves, and the resulting light field at each point of space will be determined by the interference of these waves. This principle is the basic postulate of geometric optics; however, it does not reveal physical nature of this phenomenon. Are examined the laws of the self-induction of such reactive elements as capacity and inductance, which made possible to base the physical bases of Huygens's principle. It is shown that with the connection to the sources of direct current and voltage they have the effective resistance, which depends on the time. Is examined the parametric self-induction of the elements indicated and it is shown that in the regime of parametric self-induction the capacity and inductance can not only derive energy from the power sources, but also return it into the external circuits. The new method of determining the velocity of propagation of constant stresses and currents in the long lines is developed. This task cannot be solved, using standard wave equations for the long lines. The physical special features of the work of the receiving directional Yagi antennas are examined and it is shown that the reciprocity theorem for such antennas is not carried out.

Abstract

In this study, the main objective is to present an initiative on the Grade students of the School of Industrial Engineering and Informatics, University of León. We have applied the methodology of teaching that allows enhance the interest of students for their own learning. The working method has been organizing workshops that employ strategies of project-based learning and group projects. These projects are limited in time and with a high degree of involvement by the student. There has also been an information system which supports communication and work with all of the workshop participants. For the development of this experiment, we used a microcontroller system as open source Arduino (1). This platform allows improving the teaching of electronic and automatic concepts in a simple and easy way to apply.
