These properties-including modulus, extensibility, toughness, and strength-are influenced by the morphology of the solid film, which depends on the method of processing. To date, the majority of work done on the mechanical properties of semiconducting polymers has been performed on films deposited by spin coating, a process not amenable to the manufacturing of large-area films. Here, we compare the mechanical properties of thin films of regioregular poly(3-heptylthiophene) (P3HpT) produced by three scalable deposition processes-interfacial spreading, solution shearing, and spray coating-and spin coating (as a reference). Our results lead to four principal conclusions. (1) Spray-coated films have poor mechanical robustness due to defects and inhomogeneous thickness. (2) Sheared films show the ...

In this paper, we are sending the message from the Authorized sender (Faculty) to the LCD which is connected to Raspberry Pi. A Wi-Fi is used for Data transmission. We can add or remove or alter the text according to our requirement whenever we want. A Server is used for sending notices and at receiving end Wi-Fi is connected to the raspberry pi. Wireless is a popular technology that allows an electronic device to exchange data over a wireless network, including high-speed wireless connections. The data is received from an authenticated user. The interesting part of our project is that authorized students can retrieve their academic information through voice commands or other input devices. Keywords: Wireless notice board, Raspberry Pi, WIFI based notice board

For the individual validation and authentication the biometric system has this responsibility. Biometric Technology started from the fingerprints recognition and later on improvements were done in it to make it more secure which involves the face recognition and iris Recognition. Almost both of them are available and regarded as the accurate and reliable technology for biometric validation system. This review paper is all about Face recognition techniques in biometric locking system and Iris recognition technique of identification and the ways of making locking systems ways more efficient, full of ease, more secure, and far better than before so as to make locking or security stronger. It discusses about face recognition technique, its working and its application in different sector along with iris recognition, its working, its application.
