Voice controlled robot

Personal robotic assistants help to reduce the manual efforts being put by humans in their day-to-day tasks. In this paper, we develop a voice-controlled personal assistant robot. The human voice commands are given to the robotic assistant remotely, by using a smart mobile phone. The robot can perform different movements, turns, start/stop operations and relocate an object from one place to another. The voice commands are processed in real-time, using an online cloud server. The speech signal commands converted to text form are communicated to the robot over a Bluetooth network. The personal assistant robot is developed on a micro-controller based platform and can be aware of its current location. The effectiveness of the voice control communicated over a distance is measured through several experiments. Performance evaluation is carried out with encouraging results of the initial experiments. Possible improvements are also discussed towards potential applications in home, hospitals and industries.

Automatic street lighting system using IoT

Automatic Street lighting System is a simple powerful concept, which uses LDR sensor as a switch. By using this system we can eradicate manual work at 100%. It automatically switches the lights ON when the sunlight goes below the visible region of our eyes., yet This is done by a sensor called Light Dependent Resistor (LDR) which senses the light actually like our eyes. It automatically switches OFF lights whenever the sunlight comes visible to the sensor. By using this system energy consumption is also reduced because nowadays the manually operated street lights are not switched off even after the sunlight comes visible and also switching ON earlier before sunset. In this project no need of manual operation like ON time and OFF time setting. This project clearly demonstrates the working of the transistor in the saturation region and cut-off region. The working of the relay is also known. Implementation of this project encourages digital work. Light-dependent resistor, a photoconductive device has been used as the transducer to convert light energy into electrical energy. The central dogma of the circuit is that the change in voltage drop across the light dependent resistor on illumination or darkness switches the transistor between the cut-off region or saturation region and switches OFF or ON the LED.

State of art: Micro-grid and intentional islanding of hydro distributed generation

A conventional power system is a centralized architecture in which power is generated is relatively large power plants, transmitted at high voltages and delivered to many loads that can be hundreds and even thousands of miles away. The technical solution is to integrate small and Distributed generations (DG) sources into the grid at various voltage levels. The current engineering practice for DG/Utility interconnected systems is to revert the utility systems to its original configuration(radial or meshed distribution systems) with all interconnected DG units de-energized whenever an unexpected disturbance occurs in the system. Thus, the system reliability stays at the same level as it was before integrating the DG. If connected DGs are permitted to work as microgrid and supply the local load during utility outages, the system reliability will be much better and the customers will not experience any discontinuity of their supply and can avoid loss of generation within the microgrid. When DGs operate in a microgrid environment, a central control and coordination are required. Microgrid Central controller(MGCC), a supervisory controller which co-ordinates operation between the DG, the utility grid and the algorithm is considered for the above case. The study results show that during the islanding operation the frequency and voltage are within the acceptable limit. By implementing proper control and protection schemes, DGs can be used as alternative generation backup within the microgrid during the loss of supply and hence system reliability can be improved and loss of generation can be avoided. Electric utilities should, therefore, pay special attention to their existing control and protection systems in order to incorporate intentional islanding operation in their system to retain integrity.

Study of noise reduction in single cylinder common rail direct injection diesel engine at idle speed

The design and development of modern internal combustion engines are marked by the reduction in exhaust gas emissions and an increase in specific power and torque. The reduction of noise and vibration is one of the significant attractiveness towards making diesel engines for a long time now. Countries around the world continue to legislate against the release of specific levels of exhaust gas emissions such as nitrogen oxide, hydrocarbon, carbon monoxide, and smoke. The customer requirements for combustion noise need to be met, which can be completed by optimizing the combustion system. This can be met through the development of advanced combustion systems and the increased flexibility of fuel injection systems and ECUs. This research work presents the effects of Fuel Injection Pressure on the combustion pressure and optimizing the engine noise by using Taguchi method.

Case Study

Geographical Information System (GIS) as a tool for management of an estate (A case study of three bedroom housing estate Maiduguri road Damaturu, Yobe state, Nigeria)

This paper focuses on Geographic information system (GIS) as a tool for effective management of an estate and its resources such as road, parcel building, electric poles, land use, ownership and address. The methodology includes capturing of the geometric and attribute data for parcels, buildings and other amenities such as electric poles, well, drainage system using land surveying method, creation of database (spatial/attribute) for the features in the area under study, and performing spatial analyses on the databases presentation. The geometric data acquisition was carried out using GPS and Total Station while oral interview was used for attribute data acquisition. The processed data was drafted with AutoCAD 2017 software while the database was designed using ArcGIS 10.3. Database (Extraction) queries were generated in ArcGIS 10.3 and the result of these queries is a useful tool towards decision making. These queries are useful tools for the management of the estate by the state government towards effective tax collection and provision of basic amenities. Based on the findings of this research, the following recommendations were made: Government should encourage the use of GIS, so as to create more awareness on the use of GIS as a tool for decision making, GIS is recommended in producing composite map that will show the parcels, buildings, boundary, roads, drainages, wells and electric poles, and finally, GIS is recommended to the authorities that are saddled with the responsibility of the management of an estate.

Study of adsorption of Sn(II) on synthetic three component adsorbent and to develop a method to recycle it from e-waste

In the present investigation, a technology has been developed for the separation of tin which will be applied for its recovery from the touchscreen of the mobile(E-Waste) to the extent of 92.14 ± 2.28% employing batch adsorption method. Synthetic three component adsorbing material, zirconium phosphosilicate (ZPS) material has been used as a solid phase in the adsorption. Amount of tin recovered by adsorption has been determined by using UV-Visible Spectrophotometer. (Equitronics , EQ-825) and 8.5x10-3 M Sodium morpholine thiocarbamate solution as a spectrophotometric reagent. Sn(II) forms a colored complex at slightly acidic medium with the solution of the reagent having maximum absorption at 390nm. The technique is optimized by varying amount of adsorbent (ZPS), pH, time of adsorption, etc. Under the optimum conditions of adsorption, an effect of various anions and cations in the adsorption of Sn (II) also has been studied. Interfering cations has been masked by using suitable masking agents so as to make the process more selective. It has been observed 100mg of adsorbent is sufficient to recover 5µg of tin at pH 2 and contact time of 6.0 min. The method thus developed has been applied to recover an amount of tin from the water samples spiked with tin and Indium.
