Smart intelligent aircraft structures can adapt to environmental conditions according to design requirements. They offer improvements in total weight, manufacturing cost, and operational cost. Intelligently controlling wing surfaces using on-board computers allows the wing to be "morphed" for maximum aerodynamic efficiency during different phases of flight. Adaptive compliant wings are flexible so that aspects of their shape can be changed in flight.

Smart glasses are wearable devices that display real-time information directly in front of users’ field of vision by using Augmented Reality (AR) techniques. Generally, they can also perform more complex tasks, run some applications, and support Internet connectivity. This paper provides an overview of some methods that can be adopted to allow gesture-based interaction with smart glasses, as well as of some interaction design considerations. Additionally, it discusses some social effects induced by a wide-spread deployment of smart glasses as well as possible privacy concerns.
Head-worn displays (HWD) have recently gained significant attention, in particular thanks to the release of a temporary version of Google Glass. Moreover, the anticipation of the commercial launch of Google Glass1 in the upcoming months and the fresh news that Facebook, Inc. acquired Oculus Rift2 increased the popularity of such devices even further. The trend of wearable device purchases is importantly growing and some business analysts forecast more than 20 million annual sales of Google Glass in 2018. Furthermore, researchers have been already studying and investigating HWD for several years. As a consequence, it is important to give an overview of different methods that could be used to interact with smart glasses and, above all, analysing privacy concerns and identifying the current and potential social implications related to these devices has a great significance at this point.
The main purpose of smart glasses is to provide users with information and services relevant for their contexts and useful for the users to perform their tasks; in other words, such devices augment users’ senses. In addition, they allow users to do basic operations available on today common mobile devices such as reading, writing e-mails, writing text messages, making notes, and answering calls. Therefore, although most of the usage of smart glasses is passive for the users, i.e. reading content on the little screen of the device, active interaction with such devices is fundamental to control them and supply inputs. In fact, users need ways to ask smart glasses for instance to open a particular application, answer something they need to know, insert content for emails, messages or input fields, or to control games.

Thermal and mechanical stress modelling of smart power switches under active ...CADFEM Austria GmbH
Smart power switches (SPS) for industrial and automotive applications have to withstand substantial power dissipation during operation. They are expected to work even under extreme temperature and electrical stresses, such as transient start up or overload. Several thousands of cyclic loading of electric pulses might cause failure to this SPS device. The reason behind this failure is that the electrical pulses induce thermal stress, which in turn leads to mechanical stress. Due to the multi-material design of SPS, the thermal stress often induces tractions at the material interfaces. These tractions might initiate cracks and delamination, which can lead to a device failure due to loss of electrical contact. If a crack is not nucleated, the device may fail due to overheating. Therefore, thermal and mechanical stress plays a crucial role to determine the device failure and thereby the lifetime modelling of the device. Finite Element simulation is used to analyse heat transfer and mechanical problems in SPS.
ANSYS is the FEM simulation tool which is used to perform the electrical, thermal and mechanical simulations. Electro-Thermal simulation is initially carried out in a 3D model of the SPS for various electrical pulses and as a result, the thermal stress in the model is analysed. Thermo-Mechanical chip simulation is performed with the thermal stress as loading conditions and the mechanical stress across the model is analysed. Microscopic stress simulation of the SPS sub- model is performed to analyse the stress in power metal. The electrical, thermal and the mechanical problem are solved using the FEM method in ANSYS.

Modeling & Analysis of Centrifugal Blower using Composite MaterialIOSR Journals
Centrifugal blowers are used extensively for on-board naval applications which have high noise levels. The noise generated by a rotating component is mainly due to random loading force on the blades and periodic iteration of incoming air with the blades of the rotor. The Contemporary blades in naval applications are made up of Aluminium or Steel and generate noise that causes disturbance to the people working near the blower. The present work aims at observing the choice of E-Glass as an alternative to metal for better vibration control. E-Glass, known for their superior damping characteristics are more promising in vibration reduction compared to metals. The modeling of the blower was done by CATIA V5 R19. The blower is meshed with a three dimensional hex8 mesh is done using HYPERMESH 10. It is proposed to design blower with Epoxy glass, analyze its strength and deformation using FEM technique. In order to evaluate the effectiveness of E-Glass and metal blower using FEA packaged (ANSYS). Modal analysis is performed on both Aluminium and E-Glass blower to find out first five natural frequencies

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

34. Carbon nanotube networks
Through dissolving a linear polymer inside a solid three-dimensional epoxy
matrix, so that they are miscible to each other, the linear polymer becomes
mobile at a certain temperature When carbon nanotubes are also incorporated
into epoxy material, and a direct current is run through the tubes, a significant
shift in sensing curve indicates permanent damage to the polymer, thus ‘sensing’
a crack. When the carbon nanotubes sense a crack within the structure, they can
be used as thermal transports to heat up the matrix so the linear polymers can
diffuse to fill the cracks in the epoxy matrix. Thus healing the material.
