Social media as marketing tool

With the ever-increasing use of the internet and development of web 2.0, social media has become a common platform for the marketer, businesses, and consumers for interaction. The social media has created a virtual environment where the user can create content and share. Companies have the advantage of using social media as a marketing tool to promote their products to creating brand awareness to getting feedbacks using interactive tools likes polls, questions and answers etc. The concept of social media is top of the agenda for many business executives today, so firms try to identify ways in which they can make profitable use of applications such as Facebook, YouTube, Twitter and LinkedIn.

TestoPrep: Application for aptitude test

An aptitude is a component of a competency to do a certain kind of work at a certain level. Aptitude test is designed to assess your logical reasoning or thinking performance. By practicing the aptitude test mental ability increases and which can be useful for the student to crack the exam and for employee determining which job roles are best fit for them. As aptitude test value is increasing day by day as like use for the purpose of admission and selection of student in colleges and technical institute. The objective of this paper is to provide a user with all the material of aptitude at one place and the solutions for the questions.

A review article of WDM based optical fiber communication with WDM system evolution

In the modern world, bandwidth and data rates are two most important parameters under consideration in any communication system. An optical fiber communication system is capable of transmitting the data at high bit rates and has a large bandwidth capacity. This high data rate and bandwidth capacity in an optical fiber communication system are further enhanced by using wavelength division multiplexing (WDM) in conjunction with the information transmission system, in which information from multiple sources are transferred using the same fiber, at the same time, but at different wavelengths. But the high capacity and data rates in optical WDM system is limited by nonlinear effects that occur in optical WDM system, which not only pose a limitation on the channel capacity and data rates but also degrades the performance of the data transmission system. In this paper, analysis has been done to investigate the efficiency of effect under the influence of different system parameters such as chromatic dispersion coefficient, channel spacing, transmission power level, effective area of fiber and fiber length in the form of input signals and output signals frequency spectrums.

Evaluation of stress intensity factor for turbine blade using finite element method

Gas turbines are used in trains, ships, tanks, and alongside steam turbines and in power stations to generate power. During every start-up and shutdown of an aviation gas turbine, the compressor blades are subjected to centrifugal, gas bending and vibratory loads. This repeated loading and unloading can reduce the life of compressor blades. With blading problems accounting for as many as 42 percents of the failures in gas turbines. Previous works on compressor blades have focused mainly on fatigue life estimation in the vicinity of foreign object damage. Geometric modeling of the blade was done using CAD tool CATIA. Static stress analysis was carried out to ascertain the critical region or crack zone of the blade. The maximum Von - Mises stress was found at the fillet region near the root of the blade The results of Finite element analysis showed that maximum von-mises stress was found at the 12 o‟ clock fillet region due to an influence of centrifugal stresses. The maximum Mode I stress intensity factor of 61.4 Mpa√m was found at the surface interception point, for a crack length of 6mm and crack depth of 2.4mm. With the increase in rotational velocity of 5000 rpm, 10000 rpm, and 20000 rpm, Fatigue crack length growth rate was estimated to be a 1.95 x 10-09, 1.65 x 10-07 m/cycle and 4.15 x 10-05 m/cycle and the fatigue crack propagation life was estimated to be of 4.3 x 108 cycles, 7.3 x 106 cycles and 5 x 103 cycles respectively.

Raspberry-Pi based display board using mobile application

Display board has become an important thing in institutes, organization or public places. Sticking various notices every day with new data is a very difficult process. The system can be applicable in many areas where the information needs to be circulated visually rather than in the textual format unlike the traditional ways of displaying where the information is provided but the viewers have the least interest in viewing them. The system that is being developed brings about the communication between multiple devices which are Raspberry-pi, smartphones and LCD display. The mobile application acts as a controller to the Raspberry-pi through wireless connectivity either Bluetooth or Wi-Fi, which is then connected to the LCD display for the information to be displayed

Factor affecting consumer buying behavior in Vishal mega mart retail store

Consumer Buying Behavior refers to the buying behavior of their ultimate consumer related to the market segment. A company needs to analyze buying behavior for:

• Buyer’s reactions with respect to a company or a firm. Marketing strategy has a great impact on the firm’s success.
• The marketing concept stress or emphasize that a firm should create a Marketing Mix (MM) that satisfies customers, therefore need to analyze the what, where, when and how consumers buy. So the better utility in terms of satisfaction can be given to the customers.
• Marketers can better predict how consumers will respond or react to the marketing strategies.
