A dual-band band pass filter using rings resonator for space communication

Abstract: A Dual-band BPF with parallel-coupling feed and ring resonators is designed and simulated. Parallel coupling feed, results in good coupling between input and output and good isolation between frequency bands by generating deep zero between passband. Ring resonator make filter as dual-band by shifting higher order resonating modes to desired frequency range. Filter response results in two frequency bands 4.808–5.216 GHz and 8.348–9.043 GHz covered in C and X band respectively. Some applications of these bands are mobile communication, Radio astronomy, space research and aeronautical radio navigation. Compact size (131 mm2), Small group delay (<0.43 nanosecond), large attenuation in stop band (larger than 20db till 16GHz), higher 3dB FBW (21.47% and 19.87%), small insertion loss, large return loss in passband are some advantageous factors of proposed filter design. Simulation is done using CST microwave studio 2013.

Review of Cognitive Spectrum Sensing Of Secondary User by Soft Computing

Abstract: Subjective Radio innovation is being used to give a system for using the range more beneficially, range detecting is crucial to this application. The limit of Cognitive Radio frameworks to get the opportunity to spare zones of the radio range and to keep watching the range to ensure that the Cognitive Radio framework does not cause any undue obstacle depends completely on the range detecting parts of the framework. For the general framework to work suitably and to give the required change in range effectiveness, the Cognitive Radio range detecting framework must have the ability to enough recognize some different transmissions, perceive what they are and teach the central get ready unit inside the Cognitive Radio with the objective that the required move can be made.

Network Security: A Shield to the Users

Abstract: The integration of Internet and mobile Internet, Internet of Things (IOT), promote the wide application of the industrial Internet and other vertical Internet. The Internet is spreading widely with a tremendous speed and with the spread of Internet, the security concerns are also increasing. Traditional networks of a variety of viruses, hackers and other threats expand the network to the new system, they cause damage to the system. In this paper, there is the introduction of network security, types of network security, benefits of network security combined with the safety requirements and the analysis on the level of safety requirements as well as the approaches of security detection.

Producing Biochar from Crop Residues for Safe and Environment-Friendly Waste Management and Using as an Innovative Material for Soil and Ground Improvement

Abstract: India is currently facing an acute environmental threat due to indiscriminate disposal of agricultural crop residues through open burning in the northern India. In order to utilize and manage the crop residues in an economic and scientific manner, an innovative method has been developed to make use of the crop residues to produce a useful material, called biochar which when applied back to the fields, improves the physical, agronomic, and engineering properties of the soils. Biochar is a carbon-rich and fine-grained porous material obtained from biomass through thermo-chemical conversion process called pyrolysis. Although biochar is not a new material as it had existed in other forms for centuries but the way it has drawn the attention of researchers worldwide in recent past decade, in terms of its application in soil improvement is quite a new concept. Furthermore, it is noteworthy that most of the research is based on the effect of biochar on agronomic properties of the soil so as to improve the crop production. In this paper, a novel method of on-site production of biochar, named BioCharan along with the application of biochar at different rates to the soil samples has been presented so as to assess the effect of biochar on engineering properties of soil and its overall applicability in soil and ground improvement. It has been found that biochar when mixed with cohesive soils has the potential to improve the engineering properties of the soils.

A new proof of classical Dixon's summation theorem for the series ${}_{3}F_{2}(1)$

Abstract: In the theory of hypergeometric and generalized hypergeometric series, classical summation theorems such as those of Gauss, Gauss second, Kummer and Bailey for the series 2F1; Watson, Dixon, Whipple and Saalschütz play a key role. Applications of the above mentioned theorems are well known now. For very interesting applications of these theorems, we refer a paper by Bailey [1]. Here we shall mention the following summation theorems that will be required in our present investigation. Gauss summation theorem: [2,3,4]
