Solid freeform fabrication

INTRODUCTION Today with fast growing digital age of modern technology, digital forensic experts are facing a number of data sources that they need and rely on to acquire valuable information for their investigations. Data sources can come from different forms and areas such as: personal computer, hard drives, network logs, social networking sites, mobile devices. These sources can contain a vast amount of data. Hence, they lead up to many challenges in acquiring the data. For example, just in…

Q1.Explain how the optical disk storage facility operates? Optical disk storage is an advancement of the floppy disk. The optical disk storage also called optical media is shinny and both recording surfaces are protected by two plastic plates which make it less exposed to dust and contamination. Unlike the floppy disks that store up to 1.44 of data, optical disks storages can store up to 650MB of data. They are 5.25 inches (12cm) and have a high storage density. Optical disks storage uses a high…

So you have an old Dell PowerEdge 2900 Server laying around with a few hard drives and your thinking I would really like to use this equipment as a NAS drive. It could happen, in our case it did. There were some stumbling blocks on the way though. Here is how we got through them… The goals we wanted to accomplish were creating a RAID5 array of 8 (7+1 Hot Spare) 1TB hard drives and then wanted to connect this FreeNas volume through and iSCSI channel to a file server that will present the NAS…

Hard drives have grown in size and slimmed down in size over the years. When the first hard drives were being developed they were 3.75 Megabytes, that is the size of about one high quality 3 minute song. It was 68 cubic feet big, that is the just under the average minicompact car cubic footage. And weighed just about as much as the car, the hard drive weighing in at 2,000 pounds. To access data on it it would take about 600 milliseconds, that was fast for back then. They were amazed they could…

compatible with standard USB serial Bus connection. HDD’s usually come in two sizes 2.5” and 3.5”, 2.5” HDD’s are usually found in Laptop’s and Games Consoles. 3.5” Drives are usually found in Desktop and Workstation Machines. SSD: Solid State Drive: also known as a Solid State Disk (it does not contain no actual disk) SSD’s use integrated circuit assemblies as memory in order to store data persistently. Power Supply: USB Ports: USB is an industry standard created in the mid 1990’s that defines…

ISO, PO, and Regional Counsel. 1. Draft local releases to include all information the HIPAA Breach 2. Consider the prospect of having their regional OPIA staff as a resource. 3. Give draft release to facility PO, who will send it to OIT’s Incident Resolution 4. Service. When the news release has been approved and sent out, give a copy to the facility PO and identify the media outlet(s), to which it was sent. Public Affairs Office (PAOs): Follow Up • When contacted by the news media, be…

the PCI bus. Internal Optical Disk Drive (ODD) - A slot to insert optical disks, which will then write or read data to or from the disks. Solid State Drive (SSD) - A form of hardware that stores data persistently on flash memory chips, which is roughly 500 times faster at storing and retrieving data than the magnetic storage method of HDD. Vertical NAND Solid State Drive (V-NAND SSD) - An expansion hardware that stores and retrieves data persistently; it is attached directly to the…

A novel solid-phase synthesis methodology of N-substituted-2-aminothiazolo[4,5-b]pyrazine derivatives was developed. The key step in this synthesis strategy is tandem reaction of isothiocyanate terminated resin 2 with o-halo-2-aminopyrazine, affording cyclized 2-aminothiazolo[4,5-b]pyrazine resin 4. To increase the diversity of our library, Suzuki coupling reaction was performed at the position C6. Further functionalization of 2-aminothiazolo[4,5-b]pyrazine core skeleton with various…

this task. This component ended up being the solid rocket boosters. Also, the solid rocket boosters were required to provide 80% of thrust and operate in parallel with the main engines of the orbiter for two minutes (Dunbar). Another primary function of the space shuttle is to be reusable. Majority of components needed to be reusable for future launches to cut down cost. For instance, the orbiter needs to be reusable after each launch. Also, the solid rocket boosters will be recovered and…

Application of Calculus in the Real World – Space Shuttle Launch Most people wonder what calculus can be used for in future career opportunities. For me this was easy to see because I knew what I wanted to go into. In the future, after college, I hope to go into the aerospace field and deal with things like planes, space shuttles and helicopters. At this point people, may not see the ridiculous amount of calculus I will use in the future, but in fact I will be using it daily. Whether it be…
