Opis:
Today's world mainly focuses on reducing human effort and maximizing efficiency. Machines are replacing humans in many hazardous working environments. Automation is playing an important role in saving human efforts in most of their day-to-day works. A robotic vehicle has been developed in this project which can be particularly used in a small scale industry. The robotic vehicle is controlled by a mobile phone that is connected to the robot through a GSM network which acts as a remote controller. DTMF technology is used, which enables the robot to be controlled over the GSM network. The keypad of the mobile phone acts as a remote to control the vehicle's movement. The robotic vehicle developed is not an Automated Guided Vehicle (AGV) as an operator has to manually operate the vehicle. A sensor is attached to the front of the vehicle which senses obstruction in its path and enables the vehicle to avoid collisions with moving or fixed objects. The vehicle features battery powered motors and computer technology that has been programmed to drive to and from specific points. This research work involves the fabrication of a working model vehicle controlled over a GSM network using DTMF technology. The guided vehicle can work in environments such as transporting materials from a warehouse to production lines to reduce human effort and increase efficiency.

Opis:
Worldwide, annual water demand has been increased for different uses. This can be attributed to population expansion and the accompanying need to satisfy their water needs for domestic, agricultural, and industrial purposes. The situation has been becoming worst due to vulnerable and inefficient water supply systems. Rainwater harvesting (RWH) has been proved to be a sustainable option in solving the on-ground water shortage to a great extent. India has been facing the wrath of a water crisis for about a decade or two. The potential of RWH in India is more due to its geographical location and landscape. This paper aims at studying the impact of adopting RWH techniques as an artificial recharge option to evaluate groundwater table in the Joda town of India by analyzing the difference in water levels of the township throughout the past decade (2009-19). The study revealed the increase in the underground water level of the study area and established that RWH systems are crucial in arid regions to a large extent.

Opis:
Fuel cell is an alternative renewable energy source which potentially able to replace a fossil fuel. Nowadays, common fuel cell membrane generally used is Nafion. PVDF polymer is another synthetic polymer which has excellent physical and chemical properties. The purpose of this research is to synthesize an alternative fuel cell membrane, using sulfonated PVDF doped with TiO2 nanoparticles. Sol-gel method was performed to synthesize TiO2 nanoparticles, with TiCl4 as precursor. PVDF membranes with variation of TiO2 composition (0, 1, 1.5, and 2%) were prepared with ultrasonic method. The composite membranes then were sulfonated with concentrated sulfuric acid. The composite membranes were characterized with FTIR for functional group analysis, SEM-EDX for morphology analysis, acid-base titration for degree of sulfonation, weight difference for degree of water uptake, and four point lines for conductivity. FTIR spectra of the sulfonated membrane show the existence of sulfonic group at wavenumber of 601, 1400, and 1454 cm-1. The result of SEM-EDX analysis shows that the nanoparticles of TiO2 were not distributed homogenously. Degree of sulfonation of the PVDF-TiO2 2% composite membrane is 19.54%, and its water uptake is 23.34%. The highest conductivity is about 3.17 × 10-3 S cm-1 for the PVDF-TiO2 2% composite membrane that is very close to Nafion’s conductivity, 6.08 × 10-3 S cm-1.

Recently, there are various methods to incorporate additional properties into silkworm silk, during its production in the silk gland itself. These advanced properties involve additional mechanical strength, colour, ultraviolet resistance, etc. and it is utilized for a wide range of applications. The property which focused in this study is the colour, an important quality attribute of silk. Effect of neutral red, a vital dye used as dietary supplement and its nutritional effects on Bombyx mori (B. mori) along with the colour manipulating efficiency on the larvae were observed. The colour change noticed from larval to cocoon stage confirms its efficiency to get into the silk gland of the animal crossing through the integument and haemolymph. The results of the observed nutritional parameters confirms that the selected dye in the selected concentration is suitable to produce colour cocoons without disturbing the nutritional traits such as ingesta, digesta, approximate digestibility percentage, growth rate, efficiency conversion rate, etc. of the larva. The findings elucidates that more vital dyes may use for the production of colour silk without causing any harm to the silkworm physiology. As the dye has no harmful effect in the dietary parameters, which plays a major role in the growth of the larva and production of silk, it is assumed that it may not affect the economical and biochemical parameters also. However, it has to be confirmed by further analyses.
