Effect of Reinforcement and Tribological Behaviour of AA 7068 Hybrid Composites Manufactured through Powder Metallurgy Techniques

Abstract: In this article, an attempt was made to study the mechanical behaviour of AA7068 - 6 vol. % of MoS2 - X vol. % of WC (X = 0, 5, 10 and 15) hybrid aluminium composites produced by blend–press–sinter methodology. Compacted Powders (700MPa) were sintered at different temperatures (450 0c, 500 0c and 550 0c ) in order to find the influence of sintering temperature on mechanical properties and tribological behavior of AA7068 hybrid composites.The sintered samples have been characterized by x-ray diffraction (XRD) method for identification of phases and also to investigate the phase changes. The change in density, hardness and porosity values of composites were reported. The composite with 15 vol. % of tungsten carbide and 6 vol. % of MoS2 showed the highest hardness and density at the sintering temperature range of 550 0c. Pin-on-disc type apparatus was used for determining the wear loss occurring at different conditions. The hybridization of the two reinforcements enhanced the wear resistance of the composites, especially under high applied load, sliding distance and sliding speeds. Due to this, the hybrid aluminium composites can be considered as an outstanding material where high strength and wear-resistant components are of major importance, predominantly in the aerospace and automotive engineering sectors. The morphology of the wear debris and the worn out surfaces were analyzed to understand the wear mechanisms.

Real time Monitoring of the Health of Infants

Abstract: Many a time life threatening disease become disastrous because of lack of proper monitoring systems. Continuous monitoring mechanisms can yield real time data which can predict the arrival of diseases easily and control the same before it turns out to be fatal. This work deals with developing such a system which can act as a one stop solution for all diseases which could be monitored with the aid of information on blood tests and culture tests of the same. The device to be developed takes the sample of blood and monitors it in a continuous basis. The algorithms are designed in such a way that the continuous monitoring becomes the underlying requirement. This can be a disruptive innovation. The blood sample at a point is taken without inflicting much pain. This sample acts as a basis for the underlying tests to be conducted. Such an approach facilitates the prediction of a large number of fatal diseases. Glycaemic control in type 1 diabetes during real time continuous glucose monitoring can be one of the commercial offshoots of such a development. Also, the design which suffices blood culture monitor can be an effective causal predictor for many ailments like typhoid, dengue and such other epidemics. The careful design of the same, targets the pediatric division of the health care. The analysis part has to be designed as a two-step meta-analysis which gives conclusive evidence for the diseases. It inevitably acts as a vade mecum for the such treatment designs. A real time, wearable ECG and continuous blood pressure monitoring system for first responders (Ribeiro et al 2011) is the primary motivation for such a design algorithm. This instrument elicits huge amount of real time data which inadvertently can act as a effective predictor for any upcoming fatalities. The difficulty in monitoring these parameters for the tiny tots increases the relevance of the research. The device which comes as an attachment like watch can be perfect companion for the kids and keeps a check on their health by the meta-analysis of the data collected.

On the Expressive Power of Scientific Manuscripts

Abstract: Every research manuscript is appreciated in the form of citations. Citations are expected to carry the essence of the underlying base paper by some rhetorical means. However, this is not true in reality. Citation manipulations are equally possible which shall be identified using research semantics. This paper discusses machine learning based approaches for analyzing research citations with the aim of finding quality research citations. On analyzing the semantics of the research manuscript and the respective citations, this paper proposes various metrics for citation quality analysis including deep cite, raw expressive power, expressive power and normalized expressive power.

VLSI Implementation of Image Encryption Using DNA Cryptography

Abstract: Image security is emerging as a major problem with the exponential growth of data stored and transformed through the network around the world. Many cryptographic techniques are used for securing the data like images, audio and text files. A new technique of DNA cryptography provides high security based on DNA nucleotides bases A-Adenine, C-Cytosine, G-Guanine and T-Thymine. These alphabets can be easily assigned to binary values (A-00,C-01,G-10,T-11). In this proposed model Polymerase Chain Reaction encoding technique is used in which the image to be encoded is flanked between primer keys. The DNA codons are encoded by the base of four provides keys of 256 combinations for high security, and it reduces the size of cipher text. Primer keys are generated by pseudo random sequence generator. Deciphering the image is possible with encryption key and primer sequence key. The HDL synthesis report for hardware design is implemented for encryption using verilog code on a device Virtex VII.
