Design of a protected type flange coupling using Python

Couplings are elements used to connect two shafts during power transmission. Design of couplings plays a vital role in determining the power transmission capacity of the shaft at the rated rpm, which is very crucial. The design specification of coupling varies differently based on the requirements and involves a sequential design procedure which is tedious and time-consuming. This paper deals with developing a program code for the protected type flange coupling in an Object Oriented Programming (OOP) language like “PYTHON”, which takes input (like required power input, no of rotations and desired factor of safety etc.) from designers, and then accordingly calculates the specifications of the coupling using design standard formulas and iterative procedures until the design meets the safe criteria. The final specifications are displayed along with the list of recommended materials for the coupling based on the design. The main objective of the paper is to write a generalized python program for the design of protected type flange couplings for any selected material considering all the design parameters. The activity tends to lead the manufacturing operations towards a more time-efficient, cost-effective and a more reliable and an optimised way of designing machine elements and aims to give better clarity to shopfloor workers .

Food spoilage decay monitoring using RF technology

Food industry has today become more oriented towards customer and requires quick response system. Electronic systems help in minimizing the unsafe production and distribution of food products. Currently the food labelling systems do not guarantee the good quality and safeness of the food. Hence, traceability is a tool applied to assist for assuring of food safety and its quality. We have used Active RFID system for the traceability, the communication protocol of Active RFID has been carefully designed. Energy efficient protocol has been developed and its aggregated throughput, delay and evaluation of the number of collisions happening in the radio channels is done and compared to the existing protocols, commercially available for Active RFID. In case of Marine food monitoring the TMA (trimethylamine) gas is liberated when the marine food starts to decay, using this liberated TMA gas as one of the parameters we determine freshness of food. In this paper it is also discussed about the designing and developing of the TMA (trimethylamine) sensor which can operate at normal room temperature.

A novel approach to improve the LZW data compression algorithm

The LZW data compression algorithm is a dictionary-based compression algorithm in which the process of searching for a pattern and its corresponding code to compress the data is a time-consuming process. As the file size to be compressed becomes larger the size of the dictionary also increases which increase the time to search a pattern in the dictionary. This paper proposes a novel approach to increase the efficiency of the algorithm with GPU using CUDA. Thus, making the process of searching the dictionary parallel. The result of the proposed system outlines the improved performance of the LZW algorithm

Adaptation of biomimicry in civil engineering

Biomimicry is a novel approach to developing design's and products to solve construction problems by taking inspiration from nature. It could offer a sustainable alternative solution to complex and conventional design in the best eco-friendly way. Biomimicry includes mimicking the shape, properties, methods, principles, and processes of nature. This paper reviews the existing biometric inspired civil engineering systems and architectures. In this paper various examples are taken from the nature and applied in design, like the regeneration process in lizard inspires the self-healing property of concrete, by mimicking termite mound, a passive cooling system could be developed, bridge design is one of the vital aspects of structures of biomimetics which is derived from the load carry process of trees. In a similar way, various other structures are being developed by getting inspiration from the creation of nature, as we move towards creating more sustainable construction and decreasing the carbon footprints in the infrastructure industry. Hence incorporating the potential of the mother earth will lead to the enhancement of structural stability and elegance. It will in turn preserve the earth in her best form.

Review Paper

A study on low-density parity-check codes

In this paper, relevant research advances in recent years on Low-density parity check codes are studied starting from its formulation by Gallager and rediscovery of these codes by McKay and Neal. Gallager construction of LDPC codes is described and their probabilistic decoding methods. Also, the construction by McKay is studied and the superposition method of construction is studied. Encoding and decoding techniques related to capacity-approaching error-correction technology is also studied. LDPC codes can also be described using a Tanner graph. Matrix representation and graphical representation of these codes are described. LDPC codes show better performance for more number of iterations for message passing decoding algorithm.

Effect of wind on tall building frames – Impact of aspect ratio

In modern times many tall structures and high-rise towers are being built all around the world. Because of its dynamic nature, wind plays an important role in the design of tall structures. Effect of wind is predominant on tall structures depending on location height of the structure. In this paper equivalent, a static method is used for the analysis of wind loads on buildings with the impact of different aspect ratios. The aspect ratio can be varied by changing the number of bays. Different aspect ratios were considered to carry out the present study and the analysis is carried out using STAAD PRO.
