In this paper a simple and planer new structure of dual band microstrip band pass filter (BPF) is proposed. The structure of the filter consists of stub loaded Interdigital Structure (IDS) sandwiched between two hairpin structures. Combination of IDS and hairpin structure achieves pass band response and stub loaded to IDS finger divides this pass band into two parts to create dual pass band behavior of the proposed filter. The pass band of the proposed filter covers 2.4GHz, 2.5GHz and 3.5GHz in first pass band and 5.8GHz in the second pass band. The structure of the filter is very small and simple to fabricate because structure is planar and any via or defected ground structure is not used. The filter is useful for the WLAN/WiMAX standards with good insertion loss. The FR4 epoxy material with dielectric constant of 4.4 and of thickness 1.6mm is used to design the proposed filter. The Performance of the proposed filter is found better and smaller in size than previously reported filters. © 2016 IEEE.

Significant research work is carried out at present for performance enhancement of organic devices and circuits that has become now an alternative candidate of flexible electronics technology. This research paper includes the depth analysis of a dual gate organic thin film transistor (DG-OTFT) because it has better performance in comparison to single gate OTFT structure. Subsequently, the impact of different materials for top gate dielectric is carried out, wherein, one device uses Parylene as top insulator while other device uses plasma-enhanced atomic layer deposition (PEALD) aluminum oxide (Al2O3). The performance analysis of both DG-OTFT in terms of subthreshold slope, threshold voltage, current on-off ratio and mobility is carried out using Atlas 2-D numerical device simulator. Device with Parylene organic dielectric material is observed to have better performance in comparison to its counterpart. Besides this, a comparison of performance in various modes of dual gate OTFT operation is discussed in this paper. It is observed that the dual gate mode operation shows better performance in comparison to other modes of operation. © 2016 IEEE.

In electrical power systems, isolated energy system is a more challenging task to fulfill the active power demand as well as reactive power demand under the fluctuating wind at different load conditions. In this paper, a centralized AC load, centralized distributed hybrid system (CDHS), is analyzed. CDHS has the following features in place of the DC centralized grid system, which is focused on controlling of a permanent magnet synchronous generator, a bi-directional DC-AC converter (BDC) with battery energy storage, and a wind energy conversion system with a single-stage, 3-phase 4-wire AC-AC converter connected to a common AC bus. Non-isolation of the input terminals, multi-stage operation, size and cost of the circuits, and efficient working of the AC-AC converter has been resolved using a 3-phase 4-wire AC-AC converter. A specific triggering pattern of variable frequencies to a constant frequency has been generated for the switching devices in the AC-AC converter to achieve a desired polarity of the output voltage. A BDC connects the isolated load using a natural frame instantaneous current control technique to manage the active and reactive load power flow among the parallel connection AC hybrid systems. Different conditions such as a constant load and a variable load for variable source supplies are demonstrated for the architecture of CDHS in MATLAB/Simulink. The modelling of CDHS and performance analysis have been disseminated out that the proposed CDHS is capable of managing the active power demand with reactive power for voltage variations. © 2017 Author(s).

The present paper deals with exergy analysis of a combined cycle with ammonia water mixture as the working fluid in the bottoming cycle. The effect of varying ammonia mass fraction on the thermodynamic performance of various elements of the considered combined cycle configuration is studied. The analysis reveals that as the ammonia mass fraction increases, the availability increases in low pressure gas turbine of the topping cycle, reheater, heat recovery vapor generator (HRVG), low pressure turbine, and decreases in economizer, refrigerant heat exchanger and absorber. Results obtained are useful as the exergy estimation indicates that amongst all thermodynamic elements in the considered combined cycle, the maximum availability is destroyed in HRVG followed by low pressure gas turbine which is good input for designers to improve HRVG. © 2017

Mobile adhoc network (MANET) is a collection of mobile node that can communicate with each other via radio or infra without any fixed infrastructure. MANET is a wireless network so to connect with internet any interface is needed that is called gateway which provide route to the internet. Due to dynamic topology packets are loss which degrades network operation. So to achieved high throughput security scheme are applied on internet gateway which helps to out from adversarial environment. There are some security goal is discussed (confidentiality, integrity, authentication and non-repudiation) which enhanced adhoc network operation. In this paper we survey on the gateway discovery scheme with security and without security on the basis of various performance parameter like packet delivery ratio, end to end delay, routing overhead and throughput and then conclude which one is better. © 2017 IEEE.

Cloud computing is a new form of computing which is a considered as an emerging technology for delivering service. Cloud computing consists of several consumer who demands a variety of services as per their need which changes from time to time. So it is the job of cloud computing to make the resources available to the customers according to their need. As there are limited resources so cloud computation can't fulfill the request of all the service demand of users. So cloud scheduling techniques are introduced in order to allocate resources in the fair fashion and utilize the resources efficiently. It is very crucial to provide the cloud consumer according to their QoS requirement. Hence, this paper presents the issues of performance, challenges and resource allocation techniques for cloud computing. It also focuses on the issues of existing techniques of resource allocation. © 2016 IEEE.

In the mobile environment the major issues for commit the transactions are disconnection due to mobile handoff or shut down of devices. Disconnection is frequent problem in mobile environment. This results transaction failure. A traditional two-phase commit protocol is best for the distributed environment. In case of mobile environment where devices are connected wirelessly we should deal with the issues of mobility. The paper presents comparison study of three major commit protocols in the mobile environment. The paper surveys different approaches proposed for mobile transaction and summarize how the conventional commitment are revisited to fit the needs of mobile environment. © 2016 IEEE.

Mobility is one of the major feature in the present computing environment and in the present era of computing almost all the mobile devices have the ability that they can easily be move from one location to other and the data reside on a single system can be utilize via other systems generally using the client-server paradigm. The mobile device can extract needed amount of data from the server and use in both online and as well as in offline mode, but whatever the changes being made during offline work should be copied back to the server and vice-versa whenever the server connects. As the server should always retain most recent data received from client database. So, the data synchronization is a major concern in this scenario by which data confliction can be resolved, data integrity is maintained and most recent data can be placed between the client-server. In this paper the overall data synchronization summary, architecture, tools & techniques between the two devices has been included. © 2016 IEEE.
