Optical BPSK Modulation and Demodulation using Opti System Simulator

Fibre optics deals with study of propagation of light through transparent dielectric waveguides. The fibre optics is used for transmission of data from point to point location. Fibre optic systems currently used are most extensively as the transmission line between terrestrial hardwired systems. The carrier frequencies used in conventional systems had the limitations in handling the volume and rate of the data transmission. Greater the carrier frequency larger is the available bandwidth and information carrying capacity. This paper explains about Optical BPSK, where input data is converted to BPSK data which is optically modulated by optical modulator and transmitted through an optical fibre cable. The transmitted data and received data are compared in the end.

Design and Implementation of Navi-guide Device

The device designed is a navigation guide which will help the user with turn by turn directions. At the present time, use of smartphones for the navigation support has been increased and this in turn leads to risk of accident. The navi-guide device displays step by step direction on the OLED screen. This reduces the chances of mishaps and the increases the user focus. The navi-guide app has been developed for better user interface. The rider will have to just connect his phone to the device via bluetooth can safely reach his destination without any distractions with the aid of this device.

Integrated Hand Cleaner and Dryer Product Design using QFD as a Solution for New Normal Era

At this time the coronavirus pandemic has resulted in new adaptations in daily life through new normal rules that have many rules against public activities such as using masks, keeping distance, and maintaining cleanliness by washing hands using water or hand sanitizer after interacting with objects or people in public areas. This resulted in increased use and demand for hand sanitizers and public facilities for handwashing. This study aims to obtain the design of cleaning tools and hand dryers that suit the wishes of the community. The method used in this application of Quality Function Development (QFD) by using matrix House of Quality (HOQ) to obtain the criteria of cleaning tools and hand dryers according to the wishes of the community. The results of this study obtained the design of automatic and integrated cleaning tools and hand dryers in one tool that uses a hand sanitizer made of natural antiseptic so that it does not require water and soap and with a price range of Rp.700.000

A Review on Recent Advancements in Roller Compacted Concrete

Roller Compacted Concrete (RCC) is a durable material highly used for Pavements and Dams construction. In this regard being a high qualified material for its many advantages like Faster paving, Labor savings, Tax savings etc., researchers have produced many significant studies and derived the best results by various approaches. Some research includes the study of roller compacted concrete by partial replacement of cementitious minerals such as GGBS, admixtures like Glass fibres, Synthetic Fibres etc. With the help of locally available materials many tests have been conducted and results were shared to the world for further scope of study. Roller compacted concrete (RCC) has many advantages and the main attraction is its low water requirement with high workability and high compaction. This automatically results the outstanding compression strength. Current research has been focused on the improvement of mechanical properties and durability of the roller Compacted concrete incorporating different minerals and materials. In this paper, the Review of the papers have been presented in order to come to an overall understanding of the current progress for the Roller Compacted Concrete which is mainly being used for Roads, pavements, Parking lots and Dams

Comparative Study of the Natural Fiber and Artificial Fibre as an Admixture in M30 Grade Concrete

The Sugarcane Bagasse which is produced in tones every year which can cause inconvenience to environment, we use this material as one of the admixtures in the concrete mix to reduce its effect on surroundings. As we add the material, we can economize the total expenditure on the construction. By using this we are able to improve the ordinary Portland cement through means of strength which can rise the durability of the structure. By using these materials in proportions, we produce various nominal conventional concrete mixes which are very economical and suitable for any environmental conditions. We want to use the sugarcane bagasse as the main source is an eco-friendly material, but only with this material we can’t get good strength hence it imparts strength to the concrete we are using the combination of the sugar cane bagasse and the optical fiber as an admixture. Here the test results give good improvement. Hence low-cost materials with good strength is obtained.

Healthcare Prediction and Analysis System with Constant Data Polling

The applications of Big data and machine learning in the fields of healthcare, bioinformatics and information sciences are the most important things that a researcher takes into consideration when doing predictive analysis. The Data production at this stage has never been higher and it is increasing at an alarming rate. Hence, it is difficult to store, process and visualise this huge data using customary technologies. However, abstract design for a specific massive information application has been restricted. With advancement of big data in the field of biomedical and healthcare domain, accurate analysis of medical data can be proved beneficial for early disease detection, patient care and community services. Machine learning is being used in a wide scope of application domains to discover patterns in huge datasets. Moreover, the results from machine learning drive critical decisions in applications relating healthcare and biomedicine. The transformation of data to actionable insights from complex data remains a key challenge. In this paper we have introduced a new method of polling of data before analysis is conducted on it. This method will be valuable for dealing with the issue of incomplete data and will progressively prompt suitable and more precise data extraction.
