The population of elder people is growing rapidly and these days many of them have to stay alone, independently instead of old age homes. With increasing age, people tend to forget things which may create safety problems for them. In this paper, it is proposed to develop a Wireless Sensor Network based smart home system for such elder people to help them ease their work and provide them safe, sound and secure living. A Wireless Sensor Network (WSN) is comprised of a large number of sensor nodes that are deployed in an unattended and remote environment to measure a few physiological parameters. The recent development in WSNs is the concept of Smart Homes. Smart homes integrate many devices that can sense the required parameters and control the characteristics of the home. The great progress in the industry standards and installation of lightweight wireless networking hardware over a period of time has proved ZigBee to be well suited for Smart homes and automation systems. ZigBee is a low cost, low power, less complex wireless standard. In this paper, sensors like temperature sensor, LPG sensor, Contact sensor are proposed to be deployed for fire detection, gas leakage detection and determination of whether any door is closed or open, respectively. LabVIEW is used as a graphical user interface. In case of any emergency, a warning message will be generated, and played through a loudspeaker for the user to take notice of the same and an SMS will be sent to the caregiver using GSM modem to take preventive action.

Due to the depletion of fossil fuels and increased awareness of environmental problems, the world is looking to use alternative fuels. This paper is aimed at the conversion of waste edible oil into diesel fuel, which can then be used in Compression Ignition (CI) engines. Production of edible oil was 7.6 million tonnes in 2013-14. Sunflower oil is used in majority of the houses and restaurants in India. So, the availability of waste sunflower oil in restaurants and houses is more compared to any other edible oil. Therefore waste sunflower was considered as potential oil which could be used as an alternative to neat diesel fuel. The properties of waste sunflower oil (WSO) were determined, which includes its specific gravity, kinematic viscosity, flash point, fire point, calorific value, cloud point and pour point. The waste oil was initially refined using transesterification process and again the physical properties of refined waste sunflower oil (RWSO) were determined. An experimental study was conducted to evaluate and compare the performance and emissions of different blends (B15, B20 and B25) of RWSO on a four stoke diesel engine. The results indicate that blend B20 is an optimum fuel blend in terms of increased engine performance and reduced emissions compared to neat diesel fuel.

The power sector is a highly capital intensive sector. The capital cost admitted by the regulatory commission forms the basis for determination of tariff. Depreciation, reasonable return, tax on profit, interest on long term loans, insurance etc are capital related costs, which are embedded in the tariff. A utilities profitability generally increases if it invests more in capital assets, leading to what is called `Gold plating' of investment. In this context usefulness and prudence tests are crucial at the time of approval of investment. In this paper statutory obligations which drive licensee's capital investment plans are analyzed and regulatory treatment to licensee's capital expenditure (CAPEX) plans in state of Maharashtra is reviewed.

This study presents a new approach in developing an ontology based expert system to diagnose thyroid diseases. Ontology represents explicit specification of knowledge in a specific domain of interest in the form of concepts and relations among them. Its merit is that the represented knowledge is both computer and human readable. The adoption of ontology in healthcare has facilitated domain experts and non-experts to perform knowledge representation tasks with great ease. This paper presents an ontology describing the domain of thyroid diseases and its symptoms. The thyroid gland is one of the most important organs in the body since it is responsible for controlling metabolism. Thyroid disease can be difficult to diagnose because symptoms are easily confused with other conditions. This study proposes at diagnosing thyroid diseases with an ontology based expert system called as OBESTDD (Ontology Based Expert System for Thyroid Disease Diagnosis). It uses ontology to model the contents of domain knowledge and rules to infer the related diagnosis.

In nuclear power plants, fuel is subjected to a wide range of power and temperature transients during normal and abnormal conditions. The reactor setback and step-back power pattern, fast temperature profile occurred during Loss of Coolant Accident and decay power followed by shutdown of power plant are the typical transients in nuclear power plant. For a variety of reactor engineering and reactor safety related study, one needs to simulate these transients in experimental facility. In experimental facilities, high response AC-DC converters are used to handle these power and temperature transients safely in a controlled manner for generating a database which is utilized for design of thermal hydraulic system, development of computer codes, study of reliability of reactor safety system, etc. for nuclear power plants. The paper presents the methodology developed for simulating the typical reactor decay power transient in an experimental facility. The design and simulation of AC-DC power electronic converter of 3 MW capacity is also presented. The microcontroller based programmable ramp generator is designed & hardware implemented for feeding reference voltage to the closed loop control system of AC-DC converter for obtaining the decay power profile at the converter output. The typical decay power transient of the nuclear power plant is divided into several small power ramps for simulating the transient. The signal corresponding to each power ramp is generated by programmable ramp generator and fed to the comparator for generating control signal for the converter. The actual decay power transient obtained from the converter is compared with the theoretical decay power transient.

Planar XY Flexural Mechanisms have numerous applications in precision motion mechanisms. Flexural mechanisms generate relative motion between fixed support and motion stage using flexibility of material. This type of mechanisms offers frictionless motion, zero backlash and high order of repeatability. Flexural mechanisms consist of motion stage, flexible elements (building blocks) and fixed support. Various researchers developed flexural mechanism using various building blocks; these can be broadly categorized into hinges and planar type. Present paper investigates basic building blocks of planar flexural mechanism such as single cantilever beam, parallelogram flexure and double parallelogram flexure based on various performance parameters such as deformation, stiffness, payload capacity, parasitic error, angular rotation and cross axis coupling error etc. using FEA analysis tool ANSYS. It is observed that Double Parallelogram Flexural Manipulator (DFM) offers better performance, hence experimental setup is developed using DFM. Comparison of different building blocks of flexural mechanism shows DFM offers better performance and is further experimentally validated. Also, FEA analysis of XY Flexural mechanism which uses DFM as building block is presented.

A new fabrication method for producing microchannel using metallic micromold is discussed in this paper. Microchannels have attracted different applications such as biochemistry, biomedical, lab-on-a chip and MEMS devices, etc. However, due to its lesser feature size the fabrication of it is a challenge set ahead. As microchannels have vast applications, but different feature size, finishing, materials, parameters are used according to different application. Hence, it becomes important to find out the appropriate manufacturing processes for an application. Conventional methods for fabricating microchannels are centred either etching in glass and silicon or using lithography. The major problem is that the traditional method to fabricate microchannels are not only expensive but also time consuming. It needs infrastructure and well monitored clean room environment which demands large initial investment. This paper focuses on providing a simple and economical method for fabrication of microchannels. In this proposed method, replica of microchannel is made on a brass substrate using sequential micromilling and then microchannel is produced by using PDMS as molding material. The process and selection of molding material is discussed in detail in this paper.

A lot of research has been done on the development of Microneedles (MNs) to be used as medical devices with an aim to have painless transdermal drug and improved vaccine delivery. Unlike conventional intramuscular or subcutaneous application, MN-based vaccine application delivers vaccine directly into skin and this is known to be immunologically more relevant vaccination site than underlying tissue. Various fabrication methods have been used for microneedle fabrication such as LIGA, 2 Photon Polymerization (2PP), etc. followed by subsequent Micromolding. However, despite the number of advantages of these fabrication methods, the use of microneedles is limited till date due to lesser throughput. This paper focuses on methods used for the fabrication of microneedle and also explains the proposed method for polymer microneedle fabrication using Micromolding process. Proposed method for polymer microneedle fabrication includes preparing a master structure of microneedle array, then with the help of micromold made of suitable material; final microneedle array can be made of biocompatible, thermally curable material. The microneedle array will meet the structural requirements for painless drug delivery having small invasive surface area and will withstand the force required to pierce into the skin without tip breaking.

Bhole","doi":"10.1109/ICNTE.2015.7029915","DOIUrl":"https://doi.org/10.1109/ICNTE.2015.7029915","url":null,"abstract":"A lot of research has been done on the development of Microneedles (MNs) to be used as medical devices with an aim to have painless transdermal drug and improved vaccine delivery. Unlike conventional intramuscular or subcutaneous application, MN-based vaccine application delivers vaccine directly into skin and this is known to be immunologically more relevant vaccination site than underlying tissue. Various fabrication methods have been used for microneedle fabrication such as LIGA, 2 Photon Polymerization (2PP), etc. followed by subsequent Micromolding. However, despite the number of advantages of these fabrication methods, the use of microneedles is limited till date due to lesser throughput. This paper focuses on methods used for the fabrication of microneedle and also explains the proposed method for polymer microneedle fabrication using Micromolding process. Proposed method for polymer microneedle fabrication includes preparing a master structure of microneedle array, then with the help of micromold made of suitable material; final microneedle array can be made of biocompatible, thermally curable material. The microneedle array will meet the structural requirements for painless drug delivery having small invasive surface area and will withstand the force required to pierce into the skin without tip breaking.","PeriodicalId":186188,"journal":{"name":"2015 International Conference on Nascent Technologies in the Engineering Field (ICNTE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122629603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
