Operation of logic gates (AND, NAND, OR, NOR) with single circuit using BJT (Bipolar Junction Transistor)
In this paper, we have developed a circuit which gives the output for 4-Logic gates of “AND, NAND, OR, NOR” simultaneously by taking only two inputs “A” and “B”. I used Bipolar Junction Transistors (BJT) to design this circuit. Previously we have each circuit for each logic gate but now in our new circuit, we developed four logic gates in a single circuit. Thus we can decrease the size of the special circuits. Instead of using four IC’s for four logic gates if we use this single IC for all the four logic gates then the space used for the remaining three IC’s can be used for other purposes. This circuit is very easy to design because it has only six Bipolar Junction Transistors (BJT’s).

Design of fuzzy logic controller using solar-powered BLDC motor for water pumping system
This paper is mainly based on the water pumping system by using solar PV panels for the effective cost and the brushless dc motors are used here mainly because of the easy maintenance when compare with BDC it has more advantages like high efficiency, reduced noise, longer lifetime and easy construction. The main problem which created while using the brushless dc motors is to control the system parameters. Hence, to overcome from that we introduced one main control called Fuzzy Logic Controller. It is defined as a control system based on a fuzzy logic-a mathematical system that analyses analog input values in terms of logic variables that take on continuous values between 1 or 0 which used to control the BLDC parameters thorough gate driver circuit of the boost converter. The boost converters are used here to consume more power from solar panel its nothing but the DC-DC converters. The boost converters are controlled by using maximum power point tracking (MPPT). Brushless dc motor is connected with the centrifugal pump through the shaft. The main operation of the project is operating by using the variable constructions called voltage, power, and irradiation. it is the improved version of the water pumping systems and control is done by MATLAB/SIMULINK and the hardware also been implemented.

Targeted advertising
The rapid growth of social network has led to making availability in customer tastes and preferences. This data can be exploited to serve the customers better and offer them the advertisements they would be glad to see. To provide a relevant advertisement to consumers, one has to consider the location of the consumer as well. The consumers will highly contend if the offers shown to them are easily accessible in nearby areas. Advertisements have become today’s most direct marketing channel that provides information and discount offers about products to customers and allow marketers to reach a precise goal by creating campaigns. Making these Ads location-specific would not only render them more relevant but also personalized and targeted to the specific audience. Mobile in-app advertising is growing in popularity. While these ads have excellent user-tracking properties through mobile device GPS, they have raised concerns among privacy advocates. There is an ongoing debate on the value of different types of mobile targeting, the incentives of ad-networks to engage in behavioral targeting and share user-data with advertisers, and the role of regulation.

Improving the power quality using modular multilevel converter with reduced number of switches
To eliminate the losses in the power electronic circuits, we have to include some different methods like Modular multilevel inverter. The design of a control circuit for a solar fed modular multilevel inverter to reduce the number of semiconductor switches is presented in this study. The design includes a binary mode of operation with PWM Techniques. In binary mode, 2Ns +1 − 1 output voltage levels are obtained where Ns is the number of individual inverters. MMC intends design in both control and power circuits to provide corresponding output voltage levels by appropriate switching sequences. Hence to obtain a 15-level inverter, the conventional method requires 28 switches and in binary mode 12 switches are needed but in the proposed system only 8 switches are employed to achieve 31 levels with low THD and high power quality. The advantage of this design is the reduction of total harmonic distortion.

Effect and analysis of process parameters on welded joints made by MIG welding process using design of experiment method
In industry welded joints are the most important part for making products. Welded joints are made by the various processes like TIG, MIG, spot resistance welding, arc welding process etc. For the present research study, MIG welding process is selected for analysis the welded joints. Three process parameters are selected for this study which is feed rate, gas flow rate and gap among pieces. The design of experiment method is selected for making the experiment table. The method is BB response surface method. In this method, low center and high levels are selected. Total of 30 experiments is generated using this DOE approach. One response parameter welding time is measured for this research study. Model equation generation using adequacy check is also conducted in this research study.

Universe, the fortified astral system for the life
The astral system or universe ( or cosmos) is all that was before and it ever will be. However, the concept that the astral system is all is not a scientific fact, but an assumption based upon materialistic naturalism. The contribution of Carl E. Sagan (1 November, 19324 – 20 December, 1996) in this regard was concerned with “extraterrestrial life”. The cosmological evidence proves that, the Physical Constants of the universe (astral system) are serving a lot for it’s fine tuning. It is impossible for system of human established engineering. The series of waves, the ripples in astral system from the original event of Big Bang are detectable at one part in one lakh (100,000). If this component were slightly smaller, then the present astral system would exist only as a collection of gas. Planets and life on earth may not be there. If this component were slightly larger, the astral system would consist only of large black holes. Noticeably, life would be impossible in such a astral system or universe. One more parameter for the fine tuning of astral system is the strong nuclear force. This nuclear force is responsible to hold atoms together. The fusion of higher and basic hydrogen fusion together in astral system is leading to Sun burns. Fusion of two hydrogen atoms is required for 0.7 percent of the mass of the hydrogen conversion into energy. If the amount of matter converted were slightly smaller—0.6 percent instead of 0.7 percent — a proton could not bond to a neutron, and the astral system would consist only of the hydrogen. In absence of heavy elements, there would be no rocky planets. obviously there would be no life. If the amount of matter converted were slightly larger—0.8%, fusion would happen so readily and rapidly that no hydrogen would have survived from the Big Bang. Again, there would be no solar systems and no life.
