 Abstract

This paper presents the design and the development of an interactive multimedia futuristic Smart Mirror for commercial uses in various industries. The project which would collect real world machine data and the data would be transmitted from the machine and would be managed by the Raspberry Pi. The Smart Mirror implemented as a personalized digital device equipped with peripherals such as Raspberry PI, microphone, buzzer , LED Monitor covered with a sheet of reflective one way mirror provides one of the most basic common amenities such as weather of the city, latest updates of news and headlines and local time corresponding to the location. A screen is placed behind a two-way mirror 1. By using a black and white graphical user interface (GUI) only the white colors will penetrate the mirror, resulting in an effect that makes it appear as if the mirror itself is a screen. Our lifestyle has evolved in such a way that optimizing time is the most important thing. Based on the user studies and prototype implementation, we present the development of an different application that integrate interactive services of information, offered through a user interface on the surface of a mirror. Our work is based on the idea that we all looks at the mirror when we go out, so why wouldn't the mirror become smart. The framework will offer basic services, like the presentation of personalized weather data, time, date and will incorporate some additional functionality, like reminder service by mobile synchronization and through social media. Our framework is based on detecting presence of human using Passive Infrared sensors and Wi-Fi connectivity. Once a person comes in front of the mirror, it displays the information that is being fed from the phone. This data or information includes calendar, time, weather, news feed, notifications and so on. Our framework also discusses about the face recognition and its application in control mechanism in home appliances and opening and closing of shelf. Our framework also introduces speech activated music player, and plays the music when a person gives a command.

 Abstract

Three-dimensional (3D) printing has advanced quickly, with significant medical uses. Development of biomaterials, cells, and supporting components enabling the production of functional living tissues was one of the most significant advancements leading to 3D bioprinting. Several different methods and techniques of 3D bioprinting are briefly described in this review article, and applications of 3D printing in tissue engineering and regenerative medicine, tissue transplantation, cancer research, artificial development of skin, bone and cartilage, blood vessels, liver tissue and also include the future of bioprinting in pharmaceutical applications that is Disease modelling and drug optimization, Drug toxicity screening, Precision medicine this article also include limitations and future challenges in 3D bioprinting. Further breakthroughs in the manufacture of patient-specific vascular tissue constructions will be aided by advances in additive manufacturing techniques, medical imaging modalities, biomaterials, and cellular engineering. Tissue engineering and regenerative medicine are likely to undergo significant transformations as a result of future transdisciplinary research and breakthroughs.

 Abstract

In human communication, feelings play an important role. The ability to decipher human emotions by breaking down voice is appealing in a variety of contexts. Feelings recognition can be found in a variety of places, such as the connection between PCs and people and call centres. Feeling recognition had previously relied on simple classifiers on bag-of-words models. Nonetheless, the current work on voice feeling recognition was done with the use of deep learning algorithms on static voice data. The proposed technique focuses on improving the overall precision of feeling acknowledgment during calls including artificial intelligence. The overall goal is to accurately perceive the various emotions that a single utterance conveys semantically.

 Abstract

In this paper, comprehensive thermodynamic analysis of an indirect fired gas turbine cogeneration system with multistage reheat system for heating and electricity proposes is reported. An exergy analysis carried out in the present study for improving and optimizing the overall performance of the system. This cogeneration system consists of a gas turbine cycle, a heat recovery steam generator cycle and a steam turbine cycle. A comparative study between no heat and multistage reheat shows that there is a significant improvement in electric power output, process heat production, fuel utilization efficiency and exergy efficiency due to reheat. It is also showing that the power to heat ratio is decreasing with the reheat because improvement in process heat generation is greater than the improvement in electric power output.

 Abstract

Carbon Nano Materials (CNMs) have many applications because of their super catalytical, mechanical, electrical, optical, thermal and strong electromagnetic wave absorption properties. In this work, CNM were synthesized from plant fiber and decorated with cobalt nanoparticles (Co-NPs). Microwave absorption efficiencies were studied in the frequency range of 2- 8 GHz having thickness ranging from 2-5 mm. The study concludes that CNMs decorated with Co-NPs exhibit excellent microwave absorption capability. The prepared sample shows strong microwave absorption of 96-99%, whereas -20 dB Reflection loss for 2-8 GHz frequency range of 4-5mm thickness having specific surface area of 648 m2.g-1.

 Abstract

Lightweight cryptography is a new concept that refers to a method of bettering data security through using fewer resources and providing higher throughput, conservatism, and low power consumption. Every fraction second, the Internet of Things (IoT), which links billions of devices, collects an enormous amount of data. When the number of devices grows, so does the amount of data generated, and the protection of that data becomes a concern. In IoT architecture, devices are basically smaller and low-powered. Because of their complexity, traditional encryption algorithms are computationally costly and require several rounds to encrypt, effectively wasting the limited resources of IoT devices. A less complex algorithm, on the other hand, can compromise the necessary integrity. There are many lightweight cryptography algorithms available, and we use one of the symmetric encryption algorithms called Advanced Encryption Standard (AES). The speed of this algorithm is six times that of triple DES. Since all around us is automated in today's world, automation is playing an increasingly important role in human life. The term "smart home" encompasses not only the reduction of human effort but also energy conservation and time management. Home automation enables us to control household appliances such as lights, doors, fans, and air conditioners, which require a large number of energy-constrained devices that constantly interact with one another. The security of this home automation system must not be compromised. This problem of security for automated systems is often solved by using lightweight cryptographic algorithms. For this purpose, a lightweight security algorithm is proposed in our paper that is (AES).
