The dairy industry has historically been an early adopter of technology. Rapid advances in computing and wireless systems have enabled a new era of data-intensive farming. This presentation reviews current and emerging technologies, and places them in context with the modern dairy enterprise. Research opportunities provided by the growth of this new technology are described, and the future of genomics in dairy research is discussed.

If we would see further than others: research & technology today and tomorrow

Abstract :Multimedia data security is becoming important with the continuous increase of digital communications on internet. With the rapid development of various multimedia technologies, more and more multimedia data are generated and transmitted in the medical, commercial, and military fields, which may include some sensitive information which should not be accessed by or can only be partially exposed to the general users. . The encryption algorithms developed to secure text data are not suitable for multimedia application because of the large data size and real time constraint. Therefore, there is a great demand for secured data storage and transmission techniques. Information security has traditionally been ensured with data encryption and authentication techniques. The secrecy of communication is maintained by secret key exchange. In effect the strength of the algorithm depends solely on the length of the key. The presented work aims at secure video transmission using randomness in encryption algorithm, thereby creating more confusion to obtain the original data. The security of the original cipher has been enhanced by addition of impurities to misguide the cryptanalyst. Since the encryption process is one way function, the artificial neural networks are best suited for this purpose as they possess features like high security, no distortion and its ability to perform for non linear input-output characteristics, In the presented work the need for key exchange is also eliminated, which is otherwise a perquisite for most of the algorithms used today. The proposed work finds its application in medical imaging systems, military image database communication and confidential video conferencing, and similar such application. The results are obtained through the use of MATLAB 7.14.0 Keywords: Artificial Neural networks, Back propagation algorithm, video encryption and decryption, cipher and decipher

تعريف القرص الصلب ال Hard Disk بأنه وحدة تخزين للبيانات بجميع أنواعها، وسمي صلبا لأنه مصنوع من مواد صلبة وليست لينة، ويكون مثبتا بداخل الحاسوب وعادة يتكون من أقراص ممغنطة بداخله، ومن خلال رأس مثبتة بداخله عبارة عن لاقط كهرومغناطيسي يقوم بدور قراءة تلك البيانات المخزنة، وعادة يأتي بسعات مختلفة حسب الشركة المصنعة له، هو الجزء الأساسي من بنية الحاسوب والمسؤول عن التخزين الطويل الأمد للبيانات حتى في حالة انقطاع التيار الكهربائي عن الجهاز فهو يقوم بقراءة وتسجيل البيانات بطريقه إلكترونية حیث بإمكانه تخزین كمیة كبیرة من البيانات والمعلومات بالإضافة إلى إمكانية قراءة المعلومات و البيانات بصورة اسرع بكثير من أجهزة تخزين البيانات الأخرى مثل CD-ROM و Tap drives وغيرها من الوسائل التخزينية الأخرى كما أن الغالبية العظمى من المساحة التخزينية تستخدم لحفظ البرامج و تخزينها مثل أنظمة التشغيل المختلفة والبرمجيات المتنوعة والملفات الشخصية
