The application of power electronic converters is rapidly increasing with the advancement of technology. Buck, Boost, Bidirectional dc-dc converters are widely used in renewable and energy storage systems, electric vehicle, microgrid etc. Optimal operation of these converters depend on its switching control. Controlling of a converter can be done by an open loop or a closed loop control. One such closed loop control is a Variable Structure Control (VSC). Sliding Mode control is a sub-category of a Variable Structure Control (VSC). This paper presents a comparison of the output voltage response of a buck and a boost converter having closed loop control in the form of sliding mode control and an open loop control in the form of constant frequency-variable duty, pulse firing in MATLAB Simulink.

Stereolithography - also known as SLA 3D printing is one of the most popular, emerging and widespread technology in the world of additive manufacturing. This technique basically works with the help of a high powered ultraviolet laser, which is used to harden the liquid resin by adding progressive layers on the base of built-in platform present in the tank to create the desired 3D shape. Our SLA 3D printer is generally composed of five main sections which involves a tank filled with photopolymer resin, a built-in platform, ultraviolet LEDs, Raspberry Pi and Arduino Uno. Our printer employs a hybrid approach of 3D-printing in which a modified LCD is used as a barrier between the UV LED and resin tank as well as the whole idea focuses on creating an cost effective printer. The LCD screen acts as a stencil for shaping the layers of the 3D model. The ultraviolet light from light source shines directly, in a parallel fashion, onto the build area in order to create the desired 3D model in a layer-by-layer fashion.

Hydroponics is a newly emerging agricultural technology that enables us to grow plants without the use of soil. When soil is replaced with coco-peat, rock wool or rocks, plants become highly sensitive to the nutrient solution. pH is the negative logarithm of hydrogen-ion activity, which tells us about how acidic or basic the soil, water or a solution is. It is calculated in logarithmic units and ranges from 0 to 14. Recirculating hydroponic systems absorb the nutrients from the nutrient solution. This results in a deviation of pH levels and requires timely regulation. Ideally, the pH of the nutrient solution must be between ranges of 5.5 to 6. pH probes have an output impedance of $10^{13} Omega$ and produce an analog output. They require some level of signal conditioning, which is obtained through pH modules. Generally, the pH modules available commercially are very expensive. We focus on discussing the design of an affordable pH module, interfacing it with Arduino, NodeMCU and Raspberry Pi boards.

The model developed here is used to detect specific items from the environment. The desired objects to be detected from the environment is hands(gestures). So, for computer to look at the environment computer vision is the most necessary aspect. Based, on the gesture present in the image captured along with the unnecessary objects, the image is processed and the important message is kept and rest is discarded. After processing the neural networks are introduced for to elevate the standards of computer vision there by allowing computer to know about the gesture provided by the humans. Here the recognition of the image is done by using Convolution neural network (CNN) algorithm, the gesture is predicted and this predicted result is shown on the screen connected or an audio device connected.

EMG sensor electrodes are used to detect signals from the muscle fibers and generate the required output. The basic operation of EMG signal processing are signal amplification and filtering. This low costed bionic arm is 3D printed which has its own advantage. The acquired signal is passed through various stages of filters and amplifiers for amplification and noise reduction. The analog signal is converted into digital signals. These digital signals are used to control the servo motors by using microcontroller. Specific features are extracted from the obtained EMG signals. The EMG electrodes are connected to the servo motors which are fitted inside the 3D designed arm. Mostly PLA plastic is used as a 3D printed filament.

Body Mass Index(BMI) is widely accepted as a measure to assess various health risks of a person. Eating habits, stress and lifestyle followed by an individual are some of the factors that affect our health. All these contribute towards an increased BMI and in turn to more health issues related to overweight and obesity. In this paper, the American Time Use Survey (ATUS) Eating & Health Module Files from 2014 survey is used to predict the BMI of people based on their income and through it, we try to establish a relationship between overweight/obese likely based on the income of the family. To do this analysis different machine learning algorithms will be used and finally a comparison of all the algorithms are done with the help of ROC curve.

Now-a-days the world is transcending towards e-commerce, where people get products delivered at the doorstep. This paper presents an innovative method to simplify the treatment process of a patient by using Optical Character Recognition (OCR) technique. OCR extracts the text present in an image after scanning. This can be used to identify the text written for a input image, when a doctor's prescription is given as input, the medicine name prescribed by the doctor can be identified and on that account the medicine can be shopped by using the application seemingly. The extracted text from prescription can also be used to create the reminder to take the medicine on timely manner, similarly reminding to buy the medicines again when the set or packet is about to end. This would additionally help the patient to track his medicine consumption by analyzing the graph generated by the app. Furthermore by scanning the medicine name with OCR technique, one can detail of the medicine and also the purpose for which the person consumed.

As the demand of online data availability increases for sharing data, business analytics, security of available data becomes important issue, data needs to be protected from unauthorized access as well as it needs to provide authority that the data is received from a trusted owner. To provide owners identity digital watermarking technique is used since long time for multimedia data. This paper proposed a technique which supports watermarking on database as most of the data available today is in database format. The characters to be entered as watermark are converted into binary values; these binary values are hidden in the database using space character. Each bit is hidden in each tuple randomly. Ant colony optimization algorithm is proposed to select tuples where watermark bits are inserted. The proposed system is enhanced in terms of security due to use of ant colony optimization and resilient because even if some bits are modified the hidden text remains almost same.
