The SISO voltage mode multifunctional filter topology is realized in this paper using a modified CCCCTA which realizes low-pass, high-pass, band-pass and band reject filter responses. The proposed topology consists of a CCCCTA, two 8-bit capacitor banks and a programmable input circuit using switches and VDTA. This circuit reduces the requirement of large amount of biasing current, given wider voltage...
Memory occupies more than 70 percent of area in today's system on chip and the trends continue to be increases in coming years. As the technology is scaling the bulk MOSFET faces various challenges which lead to increased leakage. Below 32nm technology, FinFET is the most promising substitute to bulk CMOS technology because of reduced short channel effect. The proposed 10T SRAM cell is designed using...
The increasing rate of Cyber Attacks based on the DDoS principle has created various new areas of concern for information security. It has also raised a pertinent question — Are we protected against such simplified attacks? With significant rise in the number of attacks and resulting reports of high vulnerability to Distributed Denial-of-Service (DDoS) attacks, perhaps we need to reconsider and revisit...
Cloud computing is entering more profound into the standard of IT. It is progressively acknowledged as imperative for both corporate and individual IT clients. In spite of the level of acknowledgment and developing innovation the lion's share of clients are still in the beginning of reception however while the information might bolster quick framework needs, it is (not happening much) that the information...
The commercial Positron Emission Tomography (PET) scanners use inorganic crystal scintillators for the detection of gamma photons. The Jagiellonian-PET (J-PET) detector exhibits high time resolution due to use of fast plastic scintillators and dedicated electronics circuits. Since the time resolution of PET scanner is influenced by numerous factors, e.g. a type of photomultipliers attached to the...
The purpose of the reported research is the elaboration of the method for construction of the cost-effective whole-body single-bed positron emission tomography scanner enabling simultaneous PET/CT and PET/MR imaging. The Jagiellonian Positron Emission Tomograph (J-PET) is built out of 192 scintillator strips arranged axially in three layers forming a cylindrical diagnostic chamber with the diameter...
Power is a major issue in today's system on chip design at deep submicron. It is very important to control power dissipation in cache memories because 70 % of chip area is covered by memory in microprocessors. Various low power circuits are proposed in the past for volatile memories to alleviate the problem of power dissipation. However in today's era nonvolatile SRAMs (NVSRAMs) are being proposed...
Image Segmentation is the procedure that breaks down any image into different parts. This is required in order to attain the essential characteristics from the image. Segmentation finds its applications in different fields of satellite imagery, weather forecasting, traffic controlling etc. But it is mainly used in the medical field to diagnose different kinds of diseases suffered by different people...
The demographics and landscape of cities are changing rapidly, and there is an emphasis to better understand the factors which influence citizen happiness in order to design smarter urban systems. Few studies have attempted to understand how large-scale sentiment maps to urban human geography. Inferring sentiment from social media data is one such scalable solution. In this paper, we apply natural...
In this work, detailed investigation of linear behavior of Gate Metal Engineered (GME) Omega Gate Silicon Nanowire (SiNW) MOSFET has been studied and results so obtained are simultaneously compared with Omega gate SiNW MOSFET using TCAD quantum study. In the comparison of GME-Omega Gate-SiNW MOSFET and Omega-Gate SiNW MOSFET, the former shows superior linearity performance in terms of higher order...
In optimal selection of a material among two or more alternatives on the basis of two or more attributes is a multiple attribute decision making (MADM) problem. In this paper we have demonstrated the use of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and modified TOPSIS in the selection of optimal material for wind turbine rotor blade design and optimal type of wind generator...

The important Linearity figure of merits (FOMs) such as second order voltage intercept point (VIP2), third order voltage intercept point (VIP3), third order input intercept point...
Software effort estimation is amongst the most important tasks in software project management as many decisions like cost estimation, deadline of submitting of project and timely planning a project are dependent on it. Many models are available for effort estimation and most widely used is COCOMO Model. A lot of research work has been done for the correct and accurate use of effort estimation models...
Mobile Cloud Computing has been worldwide accepted as a concept that can significantly improve the user experience when accessing mobile services. Mobile applications have become more popular all across the world. By removing the limitations of mobile devices with respect to storage and computing capabilities and providing new integrated levels of security by centralized maintenance of security-critical...
In this paper, we investigate the impact of gate length and channel doping of GEWE-SiNW MOSFET on the small signal behavior in terms of S-parameters such as reflection and transmission coefficients at 100Hz-4THz frequency range using device simulators: ATLAS and DEVEDIT-3D. The main aim of this work is to optimize the values of gate length and channel doping that will be projected for future reference...
Many health care providers have adopted Electronic Health Records to represent patient's health conditions. A patient visits many health care facilities like hospitals, private practices or primary health care centres for treatment of different ailments. There is a need to integrate the patient's health data from various sources, to provide a comprehensive view of the patient's health status. This...
This paper presents a fuzzy inference based object oriented classification approach for information extraction from panchromatic satellite images. The main problem concerned with high resolution satellite imagery is diverse composition of spectral resolution in urban mapping. Information extraction form these high resolution images are problematic due to discriminated object boundaries in the land...
Existence of spam URLs over emails and Online Social Media (OSM) has become a massive e-crime. To counter the dissemination of long complex URLs in emails and character limit imposed on various OSM (like Twitter), the concept of URL shortening has gained a lot of traction. URL shorteners take as input a long URL and output a short URL with the same landing page (as in the long URL) in return. With...
Packed malware imposes negative impact on the accuracy of AV scanners. It is essential for a security researcher to nullify the effects of packing tools, prior to malware detection. Numerous open and commercial packers are available to facilitate unwelcome intentions of malware authors. Thus, identification of packers becomes necessary phase prior to malware scanning. In this paper, we have proposed...
