Investigation of Shell and Tube Heat Exchanger with Nano fluid Using ANSYS

The objective of this project is to analyze net heat transfer rate in shell and tube heat exchanger using nano particle suspended in different base fluids such as Water and Ethylene glycol. The thermophysical properties of naofluid mixture like density, thermal conductivity, specific heat, viscosity and density were predicted by analytical method. Then, the shell and tube heat exchanger using aluminium metal is created using CATIA and flow and thermal analysis is created using ANASYS.

Design of Floating Point Arithmetic Unit using VHDL | IJSTE JOURNAL VOL 2, ISS 10

Design of Floating Point Arithmetic Unit using VHDL

The main objective of project is to design and verify different operations of floating point arithmetic unit (FPAU). We have designed a 64-bit AU which accepts two floating point 64 bits numbers and the code corresponding to the operation which it has to perform from the user. The AU performs the desired operation and generates the result accordingly. A pipeline floating point arithmetic unit (AU) design using very high speed hardware description language (VHDL) is introduced. The novelty of the AU is it gives high performance through the pipelining concept. Pipelining is a technique where multiple instruction executions are overlapped. In the top-down design approach, four arithmetic modules: addition, subtraction, multiplication, and division: are combined to form the floating-point AU. Each module is divided into smaller modules. Two bits selection determines which operation takes place at a particular time. The pipeline modules are independent of each other. All the modules in the AU design are realized using VHDL. Design functionalities are validated through simulation and compilation. After the coding was done, the synthesis of the code was performed using Xilinx-ISE. Test vectors are created to verify the outputs as opposed to the calculated results. Successful implementation of pipelining in floating point AU using VHDL fulfills the needs for different high-performance applications.

Factors Affecting Buying Behaviour of Rural Consumers in Dilla, Ethiopia | IJSTE JOURNAL VOL 2, ISS 10

Factors Affecting Buying Behaviour of Rural Consumers in Dilla, Ethiopia

The study is done to identify the factors affecting buying decisions of rural consumers and whether importance of these factors varies with age and income of respondents. The factors taken into consideration by the rural consumers for purchasing a commodity are price, quality, warranty, advertisement, brand, friend’s recommendations, family members recommendation and packaging. It was found that factors have an impact on rural consumer and it varies with age and income. Importance of all factors in buying behaviour of rural consumer found increasing trend with increase in their age and income. The effect of price and quality on buying behaviour of rural consumer increases significantly with increase in age and income. Advertisement and brand of products found significantly very important to high income rural consumers than lower income consumers. Friends and family members’ recommendations had significantly more impact on buying decisions of lower income consumers than high income consumers. Packaging had significantly more impact on buying decision of lower income consumers than high income consumers.
