 Abstract

As agriculture is a very important field in the Economy and social life, there exist many challenges to overcome. In this aspect, plant disease detection is one of the major issues to farmers for early detection. Many research methods had come up with the lowest turnaround time and to produce an accurate result for early identification of plant disease through proposing many algorithms and techniques. Even though there are many pitfalls found then and there, each of the techniques has given its unique results by choosing appropriate datasets and algorithms. In this paper, we studied and investigated existing techniques for the detection of early plant diseases.

 Abstract

Human is a very impatient species among all species on earth. They always try to know everything not only about earth but also about space and the universe. For space exploration, firstly they need to reach into space. Launch vehicle is the only medium to reach into space. A powerful, cost efficient and reliable launch vehicle is required for this purpose. This review paper reveals the technological evolution of launch vehicles and type of propellants are being used. The cost of launching and the problem associated with designing the launch vehicle is also outlined in this paper.

 Abstract

Nowadays, numerous problems, including the environmental problem caused by fossil fuels, have led to greater attention to the optimal use of energy and the development of renewable energy. Among the many ways introduced for energy storage, thermal energy storage, including latent heat, is among the most interesting. This storage is done with materials called phase change materials (PCMs). These materials store the energy in the form of latent heat at constant temperature during the phase transition, and release the same stored energy in the crystallization process. n-Eicosane(C20) constitute a class of solid-liquid organic phase change materials (PCMs). However, low thermal conductivity limits their feasibility in thermal energy storage (TES) applications. Adding a suitable proportion of expanded graphite (EG) into the n-Eicosane(C20) can enhance the heat transfer rate, thus improve the thermal conductivity of the whole heat storage system. In this research thermal conductivity of n-Eicosane/ Expanded Graphite composite can be determined after preparing the composite phase change material. Thermal conductivity of pure paraffin based phase change materials are varying from 0.2 W/m K to 0.3 W/m K. As compare to the pure n-Eicosane PCM, thermal conductivity of n-Eicosane(C20)/ Expanded Graphite(EG) composite phase change material ( CPCM) may increase up to 2 to 3 times by the weight percentage of Expanded graphite added to the n-Eicosane

 Abstract

Prestressed concrete sections are very much cheaper and effective as compared to reinforced concrete and therefore it has a wide use cases in bridges especially and other civil engineering structures. But nowadays curved geometry of bridges is the new trend going on , due to various reasons such as lack of space for transportation, construction in some densely populated areas to avoid traffic congestion. The use of computer software to model elements is much faster, and extremely cost efficient as compared to experimental studies in every engineering field. Here we are proposing a a design and analysis which involves the use of a computer software.

 Abstract

The paper proposes an automated wheelchair which will help the physically challenged people and serve as a complete form of this automatic system (means of mobility). The most commonly used device for differently able peoples are wheelchair. We aimed to design a solar based wheelchair with control of joystick, for moving X-Y directions. The power backup of the solar energy is saved in lead acid battery. In this project two DC motors are used for separate wheels. Using of Arduino UNO based programming joystick work. Our smart feature of this wheelchair is solar power supply and AC power supply also for (indoor/outdoor) user/uses. This report contains all the components information related to the solar based wheelchair. The proposed wheelchair system is self- driven so it is very useful for the differently able. This is the best invention in the medical field. Early wheelchairs makes the use of grid supply for recharging batteries also the cost of those vehicles was not affordable for the mid-range persons. In this case an attempt is made to design a solar based wheelchair at an affordable cost, so it can be affordable and useful for the mid-range persons. While this solar powered wheelchair has been brought to live by adding maximum technological advancement.

 Abstract

The Rubber industry is one of the most labour incentive industries. It is a major concern as the closure of the factory affects the economy of the society and the people as they lose their job. So this field deserves a deeper study and evaluation to find out the draw backs and suggest remedies. Objectives of the study, to analyse the socio economic conditions of the rubber tapping employees, to study the welfare facilities and level of satisfaction of rubber tabbing employees. Methodology of the study, Descriptive research design was used in this study. This study is mainly based on the primary data collected from the various tea plantations in the district and the secondary data from the related literatures. Primary data is generated from the respondents by contacting them personally using the interview schedule. Area for data collection was Palakkad district. The data collection started from June 2019 to September 2019. After the data collection, the data were coded, edited and tabulated. Analysis of data was done by using appropriate statistical technique. Simple percentage method and Chi-square tests were used for data analysis.Suggested this study, A supervisory body should be established to monitor the proper implemented of legilation and provision related employees.There is need of more effective poverty alleviation programme.

 Abstract

An emerging paradigm of IoT is Social IoT (SIoT). In SIoT, different IoT devices interact and create relationship with each other to achieve a common goal. In essence, Social IoT adapts a service-oriented architecture where heterogeneous IoT devices can request or offer autonomous services and collaborate on behalf of their owners. Operating Systems (OS) are employed in IoT devices because they offer threading support, access to development libraries and portability; thus allowing simplicity in IoT application development. Several OS are available for IoT devices, but selecting a hardware and OS befitting for a particular IoT application is a crucial task. In case of SIoT, the selection of specific OS for hardware devices in various applications is even more challenging due to their collaborative nature. Existing surveys on OS are mostly lack the discussion on domain oriented and hardware architectural features. As a consequence, it results in under performance in many application scenarios as it is infeasible for developers to choose best-suited OS for various hardware platforms. This paper provides an OS-to-hardware architectures features-mapping while searching the unique requirements of SIoT applications and considers quality features of OS as well as hardware IoT platforms.
