 Abstract

PolyVinyl Alcohol (PVA) is a synthetic polymer used in wide range of industrial, commercial, agriculture and medical application. It is environmental friendly, water soluble with excellent emulsifying properties. They are biodegradable and hence environmental friendly. The PVA sponges can be produced by using large closed reactors and hence are suitable for mass production. The preparation of the basic PVA solution is by adding the surfactant, catalyst, oxidizing agents, and formaldehyde. For PVA sponges many surfactants and softeners can be incorporated in order to improve its performance. The resultant PVA sponge is open-celled, highly absorbent porous material with good absorption property. The PVA sponge properties are characterized and optimized based on temperature it can withstand, height of the foam, agitation time, pH, pore structure, pore diameter, structure of the pore, chemical composition and antimicrobial activity. This paper refers to the development of PVA sponge incorporated with antimicrobial agents that is degradable which can be used for multiple applications including medical and agricultural applications

 Abstract

By the virtue of blooming automation industry and wireless connectivity, all the devices within the home can be connected. This improves the comfort, energy efficiency, indoor security, cost savings of the home. Small and constrained embedded devices are used to remotely monitor the conditions within home and control the home appliances. In such case, power consumption and network bandwidth become a major concern. A low power device that transmits messages through a less verbose protocol is needed. Owing to the ubiquitous availability of WiFi, all the appliances within home can be connected through a common gateway. An overview of a light weight Message Queuing Telemetry Transport (MQTT) protocol is presented here. In the prototype, we attempt to implement MQTT on Raspberry PI, a WiFi based development board. Sensors and actuators are connected to Raspberry PI and a Mosquitto based MQTT broker is established for remote monitoring and control. The use of MQTT hence achieves the desired result with a lower overhead and at about a 93% faster speed. The intruder detection is an added useful functionality to the system.

 Abstract

In this study the abrasive wear behaviour and mechanical behaviour of glass fibre reinforced epoxy (G-E) ,Nano Silicon dioxide filled with G-E (SiO2-G-E) and Nano Aluminium oxide filled with G-E (Al2O3-G-E) composites have been carried out by using a rubber wheel abrasion test (RWAT) , Pin-on-disc test , along with Tensile strength test, Impact strength test and hardness test. Samples of G-E with 0%, 5%, 10% and 15wt% content of SiO2 and Al2O3 were tested under different loads and abrading distances. Also, conventional weighing of specimen, determination of wear volume of the specimen, specific wear rate of the specimen, and examination of the worn surface morphological features by scanning electron microscopy (SEM) were done. The results showed varied responses under different abrading distance because of the inclusion of different wt% of SiO2 and Al2O3 filler loading. Further, the test results show that glass fabric reinforcement obviously improves the strength of epoxy and glass fabric- Al2O3 exhibits a synergistic effect on the wear resistance and reinforcing epoxy simultaneously. Further, it was also noticed that G-E composite wear is reduced to a greater extent by addition of the Nano fillers ofSiO2 and further more by Al2O3,selected mechanical properties such as hardness, tensile strength, and elongation at fracture were analysed for investigating wear property correlations.

 Abstract

A decoder and encoder is vital segments of memory, for address translating and encoding. The extent of Complementary Metal Oxide Semiconductor (CMOS) transistor continues contracting to build the thickness on contributes agreement with Moore's Law. The scaling influences the gadget execution because of requirements like warm dissemination and power utilization. A Quantum dot Cellular Automata (QCA) is a contrasting option to CMOS.QCA offers higher speed, bring down power utilization and higher thickness. It is another transistor-less calculation in nanotechnology. In this venture propose a combinational gate based decoder and encoder using Quantum dot Cellular Automata (QCA) engineering. It gives least power consumption and region minimization. A communication system can be implemented as quantum dot cellular automata. Optical communications involves encoder and decoder that can be used to generate and recognize appropriate code sequences. Hence the design of encoder and decoder is done using QCA design which ensures decrease in power and region usage.

 Abstract

The structures which are designed and construct as per earlier code provision do not have satisfied requirements for wind velocity effects .Thus many of the structures in seismic areas are suffering from hazards. Therefore the new code provisions are made for such cases. The purpose of this work is to compare the analysis of wind velocity for different terrain categories. The aim and grit is also to make proper work guidelines that can be used in practice within the early state of the design of high rise buildings as well as to find the wind induced acceleration in the top floor of skyscrapers. The wind effect analysis is carried out for seismic zone-II and III i.e., Bangalore and Chennai. The program used for modeling and analysis is ETABS V 15. The structural parameters such as column axial force, displacement changes and story shears are studied. This paper concludes that the column axial forces of structural elements depend on the terrain categories. In this project work, there has been gathered information and method has been shown to evaluate the effects of wind velocity at early state design.

 Abstract

In the present study the soil samples from paddyfield (kalikiri Andhra Pradesh),Karnataka compost development corporation limited (KCDC,kudlu village,Bangalore) & spent waste from floating type biogas plant were collected and methanogens were isolated, characterized & subjected to growth under anaerobic conditions by providing the kitchen and vegetable market waste as the substrate the kinetic study was carried out. A total of 16 isolates were obtained from the sample.The morphology and phenotypic characteristics were studied by performing various biochemical tests which revealed that the organism were anaerobes. Biogas production was carried out by using anaerobic digester.Paddy field and Biogas sample showed maximum production of biogas than KCDC. But mixed consortia had a very high degrading ability in very short period of time up to 92.95%.
