Sparse channel estimation of MIMO OFDM systems using LS and MMSE method

In wireless communication systems, Orthogonal Frequency Division Multiplexing (OFDM) is implemented widely due to its high rate transmission capability. The bandwidth efficiency and robust against multipath propagation makes OFDM as a suitable applicant for wireless communication. Channel State Information (CSI) is the vital parameter in deciding the capacity of the system. In this paper, the sparse MIMO channel is estimated using Least Square (LS) and Minimum Mean Square Error (MMSE) algorithms. The performance of these algorithms depends on the number of pilot symbols. The complexity of LS algorithm is very low but the mean square error is high. MMSE algorithm uses the second order channel statistics to reduce the mean square error. Simulation results show that MMSE algorithm outperforms LS algorithms in terms of Mean square error and Bit Error Rate(BER).

Impact of advertisement on consumer’s purchases

In order to attract the consumer's some organizations introduce new products whereas some organizations advertise in order to attract the consumers. the latter is considered to be one of the most influential ways of attracting consumers since advertising not only creates awareness about the product among the consumers but also entertains them. even though past studies have agreed that advertisement, especially tv advertisement, is the most effective media source since it attracts consumer’s attention. advertisements affect the perceptions of the consumers and it can influence the consumer's buying decisions. The purpose of this study is to determine the impact of tv advertisement on the consumer buying behavior by conducting the survey. for this purpose, a quantitative method was used, in which the impact of advertisement through brand awareness was seen on the consumer buying behavior. the main focus of this study was how brand awareness is created through tv advertising and its impact on the buying behavior of consumers, this impact is seen on the buying behaviors of consumers in electronic goods.

Designing and mathematical simulation of cylindrical and box type fired heater (used for heating of coke oven gas)

Fired heaters are used considerably in the energy-related industries and petroleum industries for heating crude oil in oil and gas sectors, refineries, DRI heater and iron ore industries. After realizing the fuel crisis and for being economical, researchers started thinking towards optimization of this process unit too. The aim of the simulation of Fired heater is to design the radiant and convection sections of heaters with consideration of multiple influencing factors. Along with, heat recovery from different sections of a fired heater and revamping possibilities to improve the heater efficiency, to reduce the flue gas temperature till the certain limit. There are a multiple influencing factors that affect the design of fired heater at the time of simulation like, type of coil, coil size, coil length, heater configuration, number of feed flow passes, a flow rate of feed and fuel type. In the present study, the comparison of simulation result on multiple influencing factors of same problem formulation in Cylindrical and Box type fired heater and discussion after changing the parameters by using the FRNC-5PC simulator.

IoT based solid waste management for the smart city

In the present day scenario, many times we see that the garbage beans or Dust beans are placed at public places in the cities are overflowing due to increase in the waste every day. It creates an unhygienic condition for the people and creates bad smell around the surroundings this leads in spreading some deadly diseases & human illness; to avoid such a situation we are planning to design “IOT Based Solid Waste Management for Smart Cities”. In this proposed System there are multiple dustbins located throughout the city or the Campus, these dustbins are provided with ultrasonic level sensors which help in tracking the level of the garbage beans and a unique ID will be provided for every dustbin in the city so that it is easy to identify which garbage beans is full. When the level reaches the extreme level, the device will send the information of the level along with the specified ID provided. The status of the garbage in the dustbins is displayed on the web page. These details can be accessed by the concern authorities from their place with the help of the Internet and an immediate action can be made to clean the dustbins.

IoT based heart attack detection using the wristband

Internet of Things (IoT) plays a vital role in connecting the surrounding environmental things to the network and made easy to access those un-internet things from any remote location. The human death due to the heart attack is increasing day by day. Due to today’s human lifestyle, eating habits, irregular daily routines, the heart attack problem is becoming predominant. So here we design a wristband which enables the early detection of heart attack and provide medical facilities as soon as possible. This mainly focuses on early detection of the heart attack which in turn reduces the human death rate due to the heart attack. And also using this device, one can monitor rhythm of heart which also helps to detect the heart attack.

Result extraction from searchable PDF

Digital documents present knowledge in most areas of study, exchanging and communicating information in a portable way. These digital repositories help in providing efficient retrieval of the stored data thus making it an important tool. Systematic extraction of data from digital document helps in mitigating the tedious work of manual data entry and facilitates effective analysis of generated structured data. The proposed system aims to extract a student's final result from the digital copy of the result sheet (PDF file) and then storing it in a centralized database which reduces the tiresome manual work needed to store records of each and every student. It provides a novel method of detecting text which is organized in tabular format and retaining the structural information after text recognition with good accuracy
