A Novel ultra-wide band (UWB) band pass filter (BPF) with triple notch bands using embedded quarter wavelength stubs is presented. The Ultra wide band filter structure consists five short circuited quarter wavelength stubs are placed at quarter wave length apart for achieving filter characteristics in frequency band between 3.1 to 10.6 GHz. Three quarter wavelength stubs are embedded in the feed line...
This paper proposes the construction of a new explicit scheme for the numerical solution of initial value problems of ordinary differential equations(ODEs). The scheme is constructed by considering a suitable approximation to the theoretical solution, which has the second order convergence and is A-stable. The proposed scheme has been tested on a variety of initial value problems. Further, it can...
A novel ultra-wideband (UWB) band pass filter (BPF) with a fractional bandwidth (FBW) of about 109% is proposed using microstrip line structure. The proposed UWB filter consists five short circuited stubs of quarter wave length are placed at λ0/4 distance apart each other in feed line of 50 Ω impedance which exhibit a very wide bandwidth from 3.1 GHz to 10.67 GHz and high rejection in out of the UWB...
Co (III) doped titanium dioxide (Ti1− xCoxO2) thin films with different Co volume ratios (x = 0.0, 0.05, 0.1, 0.15, 0.2) were successfully deposited using Sol-Gel route. X-ray Diffraction patterns revealed that the films were deposited with amorphous, anatase and rutile phases. These phases strongly influenced by annealing temperatures and doping profiles. By annealing at 500°C, the structure has...
This paper present Static Random Access Memory (SRAM) cell with minimum number of transistor. A conventional SRAM cell requires 6 transistors having two nodes contains normal and complimented data. The scaling of CMOS technology has significant impacts on working of SRAM cell. In 4T cell reading and writing has been performed by each node separately [1]. In this paper SRAM cell (2T) designed and comparison...
Use of information and communication technologies can improve the agricultural and rural development. Client server architecture in conjunction with the mobile applications on smart-phones can be useful for delivery of the precise agricultural information to the farmers. Geographical data of mobile phones can further localize the required information needs of the farmers. In this paper, an approach...
With the increasing use of computing in our day to day life it seems that Computing is 5th utility in our life after water, electricity, gas, and telephony. Cloud computing is a technology that host and deliver services over the Internet. Since the cloud computing has lots of benefits including on demand service, pay per use facility, multi- tenancy, device and location independency etc. a question...
In this paper, a lateral trench power metal oxide semiconductor field effect transistor (MOSFET) on InGaAs with voltage and on-resistance, we proposed a new power MOSFET the gate placed in a trench to provide conduction of drain to source current in the bulk of drift region. Another trench in the proposed structure is used to enhance reduced-surface-field (RESURF) effect in order to improve the breakdown...
In this paper, effect of Four-Wave Mixing has been described through simulation of 60-Gb/s alternate polarization of adjacent bits in a Dense Wavelength Division Multiplexed (DWDM) transmission link for Return to Zero and differential phase shift keying modulation formats. The optical spectra of alternate polarization return to zero (al-PRZ) system for 16 and 32 channels as well as different channel...
Wireless sensor network consists of various sensor nodes which sense the environment and forward the sensed data to the sink node. Routing in static wireless sensor network sensor nodes near the sink consume all its energy there by network partition occurs (hot-spot problem). To avoid hot-spot problem a routing in wireless sensor network using mobile sink can be used, where a sink node is provided...
Two dimensional histogram scheme has been found to be very important for data hiding. A sequence consisting of difference values between pixel pair and a sequence consisting of prediction error is computed and histogram is made. Differential pair mapping is used to hide the secret data in the cover image. One most important characteristic of proposed hiding scheme is to use adaptive embedding means...
Aluminum composites are widely used materials amongst the different category of metal matrix composite materials available. Metal matrix composites are the materials in which reinforcements are added to improve their properties. The main problem associated with the Metal Matrix Composites is their higher cost of reinforcement. To overcome this obstacle, a need arises to look for low cost reinforcements...
Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input and Multiple Output (MIMO) are two main techniques employed in 4th Generation Long Term Evolution (LTE). In OFDM multiple carriers are used and it provides higher level of spectral efficiency as compared to Frequency Division Multiplexing (FDM). In OFDM because of loss of orthogonality between the subcarriers there is intercarrier...
With the advent in technology, wireless sensor networks are used to gather information and monitor data in the inaccessible and remote areas where wired network is not feasible. Due to limited power back-up, sensor network cannot be deployed on wider scale. Processing is recommended within network to reduce communication overhead and energy consumption. Low power analog processing circuits integrated...
ERP today is very expensive and its not easy to procure it because educational institutions have limited budgets. So we have designed a modular system which can provide the educational systems more facilities with less budget also the system will be web based and it will have pay as you go model which can be achieved using the cloud based Educational ERP. E-learning tools available in the market are...
Mobile Services have become an inevitable component of human life with the high-speed mobile broadband, internet-friendly handheld devices and a wide variety of applications. The appetite for the real time web applications on the move has grown manifold. The network service providers are trying their level best to address the endless need of their subscribers but neither the user nor the service providers...
A CMOS based digitally controlled floating resistor (DCFR) is proposed using translinear cells. The proposed DCFR consists of two CMOS translinear cells along with a CMOS current-division network (CDN). The proposed circuit is designed in 0.35um technology and works at power supply of ±1.6V. DCFR is analyzed as well as SPICE simulation along with MATLAB is used to verify the proposed design. An application...
