Compare and contrast software analysis techniques Essay

Compare and contrast software analysis techniques - Essay Example After the detection of that fault in the fifth month, a software programmer was contacted and briefed with the entire story. Even a small miscalculation can lead to a bad reputation and penalties from regulatory authorities that may lead to business loss. Similarly, a software malfunction was detected in November 1979, where the strategic air commander receives an alert scramble. The scramble alarm indicated that the Worldwide military Command and Control System (WWMCCS) reported that the Soviet Union has launched missiles that are moving towards the United States of America (Software engineering (sie) 7E). Likewise, later it was found that the simulated attack was considered as a real attack, however, the U.S department of defense has not provided the details of that incident as it was marked as confidential. Conclusively, it was also a software fault that may have intimated U.S to launch a counter attack. With these two examples of billing a customer or getting false alarms in air defense, the completion time of software is always late, over budgeted or with many faults and may not cope with clients requirements. To overcome, these issues, software engineering methods are invented. Likewise, it is an attempt to provide a solution of these problems. In this brief, we will discuss two software engineering techniques i.e. formal software engineering and semi-formal software engineering. 2 Formal Software Engineering Techniques There are various formal software engineering techniques available; however, they are exceedingly diverse. For instance, Anna is considered to be a formal specification language pertaining to Ada (Luckham, von Henke, Krieg-Brueckner, & Owe, 1987). Likewise, some of the formal techniques are based on knowledge such as Gist, as it was designed for describing processes aligned with user friendliness i.e. the closest alignment of describing the process. Likewise, this is only achievable by formulating the constructs that are utilized in natura l languages. The Gist specifications are very difficult to read in practice, a separate paraphrasing tool has been deployed from Gist to English. Moreover, one more formal software engineering technique known as (Schach, 1993) Vienna definition method (VDM) is also invented. Likewise, this technique is based on DE notational semantics (Fitzgerald & Larsen, 2009). Moreover, one remarkable factor of this technique encompasses not only on the application but the design and deployment, as well. The VDM technique has been successfully applied in many projects, most amazingly on the ‘Datamatik Center development’ that was integrated with DDC AdaCompiler System (Diaz & Orejas, 1989). A unique perspective of reviewing specifications is to analyze them in the context of sequences of events. Likewise, an event can be an ordinary action or a communication signal that transmits data inward or outward of the system. For instance, a case study related to an elevator, where one event comprises of pressing the button of the elevator for floor f on elevator e along with its consequential illumination. Similarly, another event comprises of elevator e that is leaving the floor f downwards along with cancellation of illumination that is associated with conforming floor button. The CSP language abbreviated as the Communication Sequential Processes (CSP) is invented by Hoare in

Life-Altering Medical Breakthroughs on the Horizon Essay - 3

Life-Altering Medical Breakthroughs on the Horizon - Essay Example Blind people expect to have seeing ability restored. Scientists have tested and investigated microchip implants, which aid patients regain sight. Scientists are creating deep brain implants and unique glasses, which can bright sight to blind, (Barrie 1). Regenerative medication enables scientists to create organs and supplant impaired one. Researchers make substitute organs in the artificially. Presently, they have formed bladder and fixed into people. Tissue engineering utilizes both synthetic and natural material to grow body parts such as skin cells, bone marrow, cartilage among other. These technological breakthroughs provide extensive improvements for various patients and extensively reduce the cost of medication. Engineered organ replacement will outdo the hazards and challenges related to donor organs and reduce medical cost, (Reginald 1). For people who have suffered brain disease, Alzheimer or related neurological condition, the breakthroughs in neural advancements provide e xtensive hope for quality life. Similarly, microchip technology necessitates this advancement. Microchip or fiber optic wire use to bridge the affected brain parts provides a hope to cure various neurological diseases. Advancement in microchip use to bridge neural routes brings hopes to the anticipated brain use expansion for people, (Dick 1). Medical breakthroughs will allow generic condition eradication. For instance, with the human genome project completion, scientists have extensive knowledge of the genetic structure and it impacts on people. Currently, researchers can create certain gene or disease medicines utilizing DNA therapy to prevent patients against fatal diseases. It is predicted that genetic engineering will help prevent fatal conditions such cancer. Similarly, it will aid increase predicted lifespan to more than hundred years and create disease-free life.
