Breast Cancer is one of the major health concerns of women all over the world. Computer Aided Detection (CAD) aids radiologists for the early detection of abnormalities in the breast masses. Abnormalities in the breast may be cancerous or non cancerous. This work proposes an effective CAD system that considerably reduces the misclassification rates of these abnormalities. 60 mammogram images were...
This paper puts forward digital circuit design using Binary Decision Diagram (BDD). BDDs can be implemented using 2:1 mux. In this paper 2T and 4T mux are used to for digital circuit design. The BDD simulation is done using CUDD-2.5.0 tool and mux implementation is done using DSCH 2.7f and Microwind 2.6k Simulator. Experiments are performed on ISCAS Benchmark Circuits at 90 nm technology. The results...
Steganography is the art of hiding data in a particular form of media and making it accessible for the recipient. This process of encrypting data can be embedded in media like image and audio. This paper represents a snake and ladder based algorithm for encrypting a streamline of bits in a greyscale image.
During teaching and learning of canonical Computer Science courses, rigorous solving of algorithm oriented problems play a key role for thorough understanding of the core concepts. Due to teaching-learning time limitations in face-to-face and virtual learning environments, the instructor is unable to explain every step of a problem solution that is based on standard computer science algorithm. In...
The fusion of biomedical technology and wireless communication has imparted enormous comfort to both doctor and patient. Using wireless technology, vital patient parameters can be transmitted at remote locations. Also, the alternative to regular home check-ups of patients is remote patient monitoring. This paper presents the design and development of a wireless multiple vital-parameter patient monitoring...
The co fabrication of S ET & CMOS technology has already proved its ability to bring a drastic change in the era of nanodimensional devices. In our present work a well known combinational circuit, octal to binary encoder is demonstrated using hybrid SET-CMOS technology in 22 nanometer node. We have presented power analysis for the circuit here. Power delay product for the circuit has also been...
Majority of an individual's social interaction takes place through social networking site like Facebook. But one thing to focus is that the way we interact with different people through these social networking sites are different. If we are interacting with our close friends we use more informal language whereas with our relatives or elders and with our seniors at job interaction is little less informal...
This paper proposes the design of a low power, high speed, energy efficient full adder using modified Gate Diffusion Input (GDI) and Mixed Threshold Voltage (MVT) scheme in 45nm technology. The proposed design on comparison with the traditional full adder composed of CMOS transistors, transmission gates and Complementary Pass-Transistor Logic (CPL), respectively, exhibited a considerable amount of...
This paper presents an image classification method named hierarchical set of image segmentation (HSEG) for hyperspectral image. Hyperspectral imaging sensor measure the energy of the received light in tens of hundreds of narrow spectral band in each spatial position in an image. The high number of spectral bands acquired by spectral sensors increase the capability to distinguish physical material...
This work evaluates the performance of bio-inspired optimization algorithms in resolving occlusion in chromosomal images. The presence of occlusion hinders accurate identification and classification in automatic karyotyping and a manual intervention is needed to complete the procedure. For this reason, karyotyping is not completely automatic and a novel technique based on bio-inspired optimization...
