Synthesis and Characterization of Magnesium Borate via Sol Gel Method and Electrospinning Method

The sol gel and electrospinning techniques were used to prepare the magnesium borate polyvinyl alcohol composite. The fibers of magnesium borate about 150 nm diameters, were synthesized from the inorganic organic composite fibers by high temperature calcination process. The synthesized magnesium borate nanofibers were structurally investigated by thermogravimetric differential thermal analysis TG DTA , Fourier transform infrared spectroscopy FT IR , X ray diffractometry XRD and Scanning electron microscopy SEM , respectively. Due to the Mg modification of the B2O3 network, incomplete crystallization of the samples was observed when heat treated at 800 °C. But, completely crystalline fibers were obtained after calcined at 1200 ° C.

Real Time Implementation and Investigation of Wireless Device of Electrical Stimulation for Peripheral Nevers

Electrical nerve stimulation ENS is the delivery of electricity across the intact surface of the skin to activate underlying nerves generally with the objective of pain relief. Wearable Intensive Nerve Stimulation WINS is an emerging form of ENS in which the device is wearable, automated, and designed for intensive use. This enables regular use throughout the day and night, whenever the patient experiences pain, which is essential for the management of chronic pain. Hence we design and develop a wireless controlled smart tiny wearable medical device that is capable of passing electricity through underlying nerves of human beings for symptomatic relief and management of chronic pain. This project can be applicable for coma persons. When there is a slight improvement in their acceleration, this device will stimulate the peripheral nerves accordingly.

Comparative Study of Different Approaches for Measuring Difficulty Level of Question

Semantics based information representations such as ontologies are found to be very useful in repeatedly generating important factual questions. Formative the difficulty level Of these system generated questions is helpful to successfully make use of them in various learning and specialized applications. The accessible approaches for result the difficulty level of factual questions are very simple and are limited to a few basic principles. We suggest a new tactic for this problem by considering an edifying theory called Item Response Theory IRT . In the IRT, facts skill of end users learners are considered for assigning difficulty levels, because of the assumptions that a given question is apparent differently by learners of various proficiencies. We have done a detailed study on the features factors of a question statement which could perhaps determine its difficulty level for three learner categories experts, intermediates, and easy .

Design for Additively Manufactured Structure An Assessment

The design of lightweight structures realized via additive manufacturing has been drawing considerable amount of attentions in academia and industries for a wide range of applications. However, various challenges remain for AM lightweight structures to be reliably used for these applications. For example, despite extensive advancement with geometric design, there still lacks adequate understanding with the process material property relationship of AM lightweight structures. In addition, a more integrated design approach must also be adopted in order to take non uniform material design into consideration. 

In our works, a design approach based on unit cell cellular structure was taken in the attempt to establish a comprehensive design methodology for lightweight structures. Analytical cellular models were established to provide computationally efficient property estimation, and various design factors such as size effect, stress concentration and joint angle effect were also investigated in order to provide additional design guidelines. In addition, it was also found that the geometry and microstructure of the cellular structures are dependent on both the process setup and the feature dimensions, which strongly support the argument to establish a multi scale hierarchical cellular design tool.

Socially Aware Device To Device Communications

Device to Device D2D correspondence is a basic part towards the appropriation of new ideal models, for example, edge and haze figuring. While a ton of work has shown the extraordinary capability of D2D correspondence, it is as yet vague whether the advantages of the D2D approach can truly be utilized by and by. It is contended that immediate correspondences worldview points of interest may not be completely caught without grasping the ideas of the social space. Following the blast of informal organizations and brilliant cell phones, social associations among versatile clients empower the advancement of D2D co tasks. Cell phones are a basic piece of our everyday life. We utilize cell phones for correspondence, amusement, social mindfulness, diversion. Here we focus on Social mindfulness as can be present moment and long haul.

 Present moment synchronous mindfulness is attention to a social circumstance at a specific minute. Long haul nonconcurrent mindfulness is consciousness of the social circumstance when all is said in done and over a specific timeframe. This commitment is put together both with respect to the writing study and on the experimental information gathered among particular social administration office. As the fundamental objective of this application is to contribute for a superior comprehension of the issue on supporting social mindfulness among the general public and to give a last arrangement of condition issue. Moment notice and refresh for the reasons of social issues to survive.

Performance Enhancement of DC Load and Batteries in Photovoltaic System

To avoid the pollution and to save the non conventional resources, use of renewable energy sources such as wind energy, bio gas, hydro and solar potential has increased and become essential to adopt a low cost generating system in remote areas. Besides the variety of energy sources, solar power advantages are easy to make apparent compared to other methods. For many years, solar energy is the series source of vast amounts of freely available energy, but modern technology has harnessed it. In this paper a proper battery charge controller used in the Standalone Photovoltaic PV system. The power is transfer to the dc load and manages storage level available in this proposed technique. From the PV array the maximum power is extracted by using three different methods. In this proposed technique ‘perturb and observe' and the ‘incremental conductance' control methods and algorithms are analyzed. The system modelling as well as simulation results are presented.

IIR Filter Design for De Nosing Speech Signal using Matlab

The design of filter has become the core issues of the signal processing. Generally speaking, filter can be divided into analog filter and digital filter. Today, the development of analog filter has been more mature. However, digital filter has many advantages, such as higher stability, higher precision. With the development of digital technology, using digital technology to realize filter function is widely used. A MATLAB based digital filter design procedure designs the filter and applied to the voice signal. In this project, the recorded speech with simulated noises is processed. The speech signal “I Love Electronics” is taken as the input signal. AWGN is added with the input speech signal. Two types of IIR filters Butterworth and Chebyshev are designed and are applied to the noisy speech signal. The magnitude response, phase response, impulse response and order of the filters are generated.
