CASE STUDY NO.1 THERAC – 25 Aaron James Uy Timosa BSIT – 4 INTRODUCTION The Therac-25 was a radiation therapy machine produced by Atomic Energy of Canada Limited (AECL) after the Therac-6 and Therac-20 units (the earlier units had been produced in partnership with CGR of France). It was involved in at least six accidents between 1985 and 1987‚ in which patients were given massive overdoses of radiation‚ approximately 100 times the intended dose. These accidents highlighted

Computers are increasingly being introduced into safety-critical systems and‚ as a consequence‚ have been involved in accidents. Some of the most widely cited software-related accidents in safety-critical systems involved a computerized radiation therapy machine called the Therac-25. Between June

up of 2 classes of protiens that allow vesicle fusion called the v-snares and t-snares. The v-snares are found on the vesicle and include synaptobrevin. The t-snares are located on the target membrane and has two components called syntaxin and SNAP-25 (Karp‚ 2008). The SNARE proteins are fixed tightly within the vesicle and target membrane by transmembrane domains. When the target membrane and vesicle come into contact and dock with each other the SNARE motifs composed of four alpha helices interact

HOMEWORK WEEK 6 9.) Compare and contrast circuit-switched services‚ dedicated-circuit services‚ and packet-switched services. Circuit switched services are the oldest approach to MAN and WAN circuits. They began operating over the PSTN or the Public Switched Telephone Network that carriers like AT&T‚ and Bell South ran on. A simple telephone call is based off of this premise. Circuit switched services rely on cloud architecture. This means that the users must lease connection points into the

FEB 25‚ BERLIN---The Philippine Embassy and the Filipino community in Berlin commemorated the 26th anniversary of the 1986 EDSA People Power revolution‚ by reliving the vivid memory of the historic event. Though many of the Filcom members were too far away from home at the time‚ they reminisced the thought of how the EDSA spirit inspired other countries to aspire for their freedom‚ including the people power that led to the Fall of the Berlin wall in October 1989. The commemoration

An example of a reliable packet service is Frame relay‚ which is a packet switching technology that transfers data faster than x.25 but slower than ATM. X.25 is another example of a reliable packet service. An unreliable packet service doesn’t check for an error and the packets aren’t guaranteed to reach its final destination. An example of a unreliable packet service is ATM. Describe five

Ethernet Switching Modes NTC/405 March 2‚ 2015 Ethernet Switching Modes Ethernet is one of the most popular networking architecture for LANs. It can offer high performance‚ low cost‚ and it is also easy to install and manage. The work of the IEEE 802.3 committee defines the standards of Ethernet and there are also various Ethernet implementations that can support any business’s needs. This paper will distinguish the basics between channels and circuits‚ Ohm’s law‚ and network protocols. Network

History of the OSI Reference Model Looking at the origins of the OSI Reference Model takes us back to several issues that were discussed in the Networking Fundamentals chapter of this Guide; specifically‚ I am talking about standards and standards organizations. The idea behind the creation of networking standards is to define widely-accepted ways of setting up networks and connecting them together. The OSI Reference Model represented an early attempt to get all of the various hardware and software
