The study presents results from applying the Real Aperture Radar interferometry technique and Digital Image Correlation through a mobile phone camera to identify static and dynamic deformations of a gantry during surveying operations on the Michelangelo’s David at the Galleria dell’Accademia di Firenze Museum in Florence. The statue has considerable size and reaches an elevation of more than seven meters on its pedestal. An ad-hoc gantry was designed and deployed, given the cramped operating area around the statue. The scanner had a stability control system that forbid surveying in instrument movements. However, considering the unicity of the survey and its rare occurrence, the previous survey had been carried out in the year 2000; verifying stability and recording deformations is a crucial task, and necessary for validation. As the gantry does not have an on-board stability sensor, and considering the hi-survey accuracy requested, a redundant, contactless, remote monitoring system of the gantry and the statue stability was chosen to guarantee the maximum freedom of movement around the David to avoid any interference during scanning operations. Thanks to the TInRAR technique, the gantry and the statue were monitored with an accuracy of 0.01 mm. At the same time, a Digital Image Correlation analysis was performed on the gantry, which can be considered a Multi-Degree-Of-Freedom (MDOF) system, to accurately calculate the vibration frequency and amplitude. A comparison between TInRAR and DIC results reported substantial accordance in detecting gantry’s oscillating frequencies; a predominant oscillation frequency of 1.33 Hz was identified on the gantry structure by TinSAR and DIC analysis.

The isolation of genetic markers, like drug resistance and auxotrophy, is a laborious but important step in genetic research. The isolation of auxotrophic mutants of Trichoderma harzianum using the filtration enrichment technique was more effective than using the total isolation technique. Most of 12 auxotrophic mutants exhibited similar growth rate and higher sporulation when compared with the wild type, but only two mutants (TWS-410 and TW5-523) could grow in 500µg/L of benomyl.

Digital image correlation may be useful in many different fields of science, one of which is medicine. In this paper, the authors present the results of research aimed at detecting skin micro-shifts caused by pulsation of the veins. A novel technique using digital image correlation (DIC) and filtering the resulting shifts map to detect pulsating veins was proposed. After applying the proposed method, the veins in the forearm were visualized. The proposed technique may be used in the diagnosis of venous stenosis and may also contribute to reducing the number of adverse events during blood collection. The great advantage of the proposed method is the lack of the need to have specialized equipment, only a typical mobile phone camera is needed to perform the test.

Nowadays, the development of celluler device especially mobile phone is very rapid. The security of information in mobile phone becoming such an important thing, because users do not want other people can access their essential information. It means in the security in mobile phone. One way to secure the data is steganograpgy technique. This technique hides the data in a digital media. In this research the steganography technique that the is used is the Least Significant Bit (LSB) which implemented to cellular equipment with android as the operating system. The digital image which is used to hide the data is PNG. The test result shows that steganography has been implemented successfully in android phone. In the imprecebility aspect, user cannot different between the picture with message and the original picture bare eyedly. In recovery aspect, the message successfully encrypted and decrypted without changing the original content of the message. The lack occurs in fidelity aspect which the expansion of PNG file happens. Index Terms—LSB, least significant bit, png, android, handphone

Penjelajahan lapangan sering diperlukan untuk tujuan penelitian ataupun dokumentasi. Berbagai macam resiko diabaikan demi tereksplorasinya suatu tempat. Serangan binatang buas dan cuaca ekstrim menjadi contoh bahaya yang dapat menimbulkan resiko apabila penjelajahan melibatkan manusia secara langsung. Medan yang sulit juga dapat menghambat penelitian serta pengambilan dokumentasi. Untuk mengatasi permasalahan di atas dibuatlah Rover Bogie Robot. Pada robot terpasang kamera guna memudahkan penelitian dan dokumentasi. Robot yang didesain berupa robot penjelajah dengan suspensi passive rocker bogie. Robot penjelajah ini bisa melalui berbagai medan dengan karakteristik yang berbeda. Gambar dokumentasi akan diolah pada Digital Image Processing yang akan mempermudah observasi. Mikrokontroller yang digunakan pada robot ini yaitu Arduino Mega. Kamera yang digunakan adalah IP Camera pada mobile phone dengan menggunakan aplikasi IP Webcam dan Configure IP Adapter serta LabVIEW Vision sebagai GUI (Graphical Unit Interface) dan kontrol pengambilan gambar. Sebagai pengendali, digunakan wireless joystick. Digital Image Processing yang digunakan yaitu Extract Single Color, Threshold Image, Edge Detection dan RGB Gain. Berdasarkan pengujian, pengolahan gambar menggunakan Digital Image Processing dapat bekerja sesuai dengan yang diharapkan. Robot dapat melewati berbagai karakterisitik medan yaitu bebatuan ringan, berumput rendah, medan dengan permukaan tidak rata dan naik dengan ketinggian maksimal 5 cm. Pengujian kontrol menggunakan wireless joystick dapat dilakukan dengan jarak maksimal 11 meter. Secara keseluruhan, Rover Bogie Robot dapat digunakan sebagai media untuk penjelajahan yang bertujuan untuk penelitian dan dokumentasi pada medan dengan karakteristik yang berbeda menggunakan kontrol wireless joystick.

This paper output is a music player application but when it comes to its features it will be way more than a simple music player. It is developed on Android Studio and other tools like: Firebase is used as database, Android phone camera, Music library of Android Phone are used in the development of application. When user changes his phone or reset his phone then all of his data is lost or user has to put all the data in his computer and then back to his mobile phone except data that is backed up online. Message data, photos and contacts are that things that users backed up online. But music files normally don’t get backed up and user troubles in re downloading the files or moving files in computer and back to phone. In this purposed work the targeted problem is resolved as MUSYNC application is be able to automatically backup all the mp3 data from the phone and user will get all of his data by just signing in the application in his new phone. The purposed application has a feature of sync music. Users can sync music with another one and that person will able to listen to same music instantly. Application also provides a unique feature of mood detection using digital image processing DIP. This feature is able to check your face emotion and play music according to it. User just has to take a picture and that is it, this music player plays the music according to your mood. This feature is useful when user having tough time what to listen.
