...Failures Paper Charles Persinger University of Phoenix POS/355 Jeff Rugg April 28, 2014 Simply put, distributed computing is allowing computers to work together in groups to solve a single problem too large for any one of them to perform on its own. Distributed computing is not a simple matter of just sticking the computers together. For a distributed computation to work effectively, those systems must cooperate, and must do so without lots of manual intervention by people. This is usually done by splitting problems into smaller pieces, each of which can be tackled more simply than the whole problem. The results of doing each piece are then reassembled into the full solution. As handy as a distributed system can be there are a there are four main issues you could face: Operating system failures, Hardware Failures, Omission Failures and Byzantine Failures. Crash failures are caused across the server of a typical distributed system and if these failures are occurred operations of the server are halt for some time. Operating system failures are the best examples for this case and the corresponding fault tolerant systems are developed with respect to these affects. Hardware failures used to be more common, but with all of the recent innovations in hardware design and manufacturing they tend to be fewer and far between with most of these physical failures tending to be network or drive related. With more hardware the probability goes up that there will...

...Source: Marin County sues Deloitte: Alleges fraud on SAP project The success or failure of implementing ERP software depends on a number of factors. I will look at the case Marin County sues Deloitte: Alleges fraud on SAP project. Marin County filed a complaint against Deloitte Consulting for its role in an over-budget SAP implementation. The lawsuit alleges Deloitte committed fraud and misrepresented its skills and experience. One of the reasons why this ERP system failed was Deloitte knew the County didn’t have any prior ERP or SAP implementation experience and knew it would be depending on Deloitte to guide and manage the project. The complaint also states that Deloitte mishandled staffing, project management, risk management, and testing. When implementing ERP software customers, software vendors, and system integrators typically share responsibility for project success of failure. However, customers purchasing complex systems, such as ERP software, do have a high responsibility that their own projects outcome is successful. In Marin’s contract suggested the County was concerned about its own ability to manage the project properly. Being concerned with your own company’s ability to manage a project in the early stage of implementation is not a good thing and Marin County should’ve controlled the conversation with their system integrators and lead from that premise. It’s up to the customer such as Marin County to lead and drive the result of their ERP implementation project...

...Examining a Business Failure Paper Rhonda Ellis-Thomas LDR/531 May 30, 2012 Dr. Felicia A. Bridgewater Examining a Business Failure Paper 2002 has witnessed its share of scandals. Enron, WorldCom, Tyco, and Global Crossing are just a few names to mention. WorldCom, the nation’s No. 2 long-distance phone company, filed for Chapter 11 bankruptcy protection in July 2002, approximately one month after it publicized that it had indecorously booked $3.8 billion in expenses (Beltran, 2002). The purpose of this paper is to describe how specific organizational-behavior theories could have predicted or explained the company’s failure and compare and contrast how leadership, management, and organizational structures contributed to the failure. From 1991 to 2002, WorldCom has efficaciously acquired 65 companies in which 11 of the companies were established in the first six years. WorldCom was the second largest long distance telecommunication company being succeeded by AT&T. The company has accrued over $40 billion of debt (Moberg & Romar). During this time, WorldCom was headed by Chief Executive Officer (CEO) Bernard Ebbers and Chief Finance Officer (CFO) Scott Sullivan. The CEO and CFO generated a structural philosophy, or belief, where the leaders and the managers are not to be suspected or questioned (Scharff, 2005). These behaviors lead to unethical and deluded activities that would later cause the fall of...

...Running Head: ENRON BUSINESS FAILURE Examining a Business Failure Paper Enron Rachel Y. Pointer University of Phoenix LDR/531 Ernest Price, Instructor January 17, 2010 Enron Business Failure One of the world’s most catastrophic business failures was Enron. Unveiled in October 2001, this scandal involves the renowned energy company Enron in conjunction with the accounting, auditing and consultancy schemes of Arthur Andersen. Enron disgraces ultimately lead the organization to a scandal that resulted in the biggest economic failure in United States history (TIME Enron, 2001). The Enron scandal also destroyed one of the foremost accounting agencies in the world, Arthur Andersen. Enron’s downfall was the result of their choice of accounting practices, in particular target entities and poor financial reporting. Enron’s accounting structure had so many loopholes that it was unproblematic for Andrew Fastow, the organization’s chief financial officer, to mask billions in debt from failed transactions and schemes. Fastow and other main executives purposely misinformed the organization’s board of directors and audit commission. The U.S. Securities and Exchange Commission (SEC) began an investigation into Enron after the organization’s stock price began to plummet and Dynegy offered to purchase Enron at a price much lower than normal market price. When the Dynegy deal did not happen, Enron filed for bankruptcy on December 2, 2001 under Chapter 11 of the...

... March 11, 2013 Bhupinder Singh Failures Paper The distributed systems are unique in that it’s executions of the application of the protocols are to coordinate on multiple processes on the network, they have their own local memory and it communicates in entities with each of them using a massage passing mechanism. They also have their own personal users to them that they can use for personal uses. What are shared across the distributed systems are the data, processor, and the memory that can achieve those tasks when processing information. The distributed system has features to help achieve in in solving problems and issues with software and programs, when being useful with the distributed system is not very easy; its capabilities are the components, than just the stand alone systems that are sometimes not as reliable. Because of the complexities of interactions between running the distributed systems, it must have special characteristics like the fault tolerant; this can recover from component failures without performing incorrect actions. Recoverable is where failed components can restart and then rejoin the system after the cause failure has been repaired. The failure on a distributed system can result in anything from easily repairable errors to a catastrophic meltdown. Fault tolerance deals with making the system function in the presence of defaults. Faults can occur in any one of components. In this paper we will look at the different faults in...

...I love challenging myself. I know I will not always succeed, but that doesn’t stop me from trying my hardest anyway. As Michael Jordan would say, “I can accept failure. Everyone fails at something, but I can't accept not trying.” During my junior year at Maine East High School I took three AP courses, one of which was AP chemistry. My friends told me I was setting myself up for “failure” as AP chemistry is a difficult class, but I called it “a challenge to overcome.” I want to be a doctor, and I know that chemistry is a subject I must know well. I set my eyes above the horizon to earn an A in the class. However, I was a bit overconfident, as the year before I had easily earned an A in a standard chemistry class. When I received a D on my first test, I quickly realized I had to change my study habits in order to overcome this hurdle. I started...

...Heart failure occurs when cardiac output is insufficient to effectively perfuse the tissues, despite normal filling of the heart. Usually causes include hypertension, cardiomyopathy, and coronary heart disease. In heart failure, the increase in the resistance against which the heart pumps (afterload) further depresses cardiac output. A reduced renal blood flow induces renin secretion and increased plasma aldosterone and angiotensin concentrations. Water and sodium retention increases blood volume causing central venous pressure to increase. These changes overall first help to maintain cardiac output however in the long term they eventually cause morbidity and mortality (BOOK). Treatment of heart failure begins with angiotensin converting enzyme (ACE) inhibitor and as severity increases a diuretic is added which supports the excretion of sodium and water (book). In very severe heart failure, the addition of β-blocker further decreases mortality in patients on ACE inhibitors and diuretics. Valsartan/ Sacubitril is a combination drug approved for use in heart failure. It has a brand name of Entresto and is also previously known as LCZ696....

...Introduction Heart failure is a condition in which the heart cannot pump enough blood through the body. When this happens, parts of the body do not get the blood and oxygen needed for them to function properly. This can cause symptoms such as shortness of breath, fatigue, and confusion. There is no cure for heart failure. However, following your health care provider's instructions about a healthy lifestyle and being treated with medicines can help you stay active and live longer. The types of medicine you are prescribed will depend on your symptoms and what is causing the heart failure. In some cases, you may need to take more than one medicine. It is important to talk to your health care provider about all the medicines you are taking, how...

...Chronic Liver Failure Alcohol Abuse & Cirrhosis Alcohol abuse is one of the most common causes of cirrhosis, and one of the leading causes of severe liver damage worldwide (Doig & Huether, 2010). It is interesting to note that alcoholic cirrhosis is responsible for 50-70% of all underlying liver pathologies in ACLF in the Western countries and only 15% in Asian countries (Kim & Kim, 2013). Strong alcohol odor, significantly high blood alcohol levels, lethargy, peripheral edema, ascites and abnormal protein levels are all signs of a patient’s chronic alcohol abuse. Alcohol is a potent hepatotoxin (Park et al., 2014). Liver has an essential function of de-toxifying alcohol and its toxic products. Two enzymes, alcohol dehydrogenase and aldehyde...

...amazing things through its four chambers and two ventricles. The most important functions the heart does is pumping blood and oxygen through our body. Those two functions are what keeps us alive and breathing. A person's most important goal should be to remain healthy in order to avoid any type of health issues. However, most people don't really realize the health issues that can occur in your heart when your health is not up to par. One of the most common health issues regarding the heart is congestive heart failure. This health issue occurs when the right ventricle has difficulty pumping blood to your lungs. When a ventricle has difficulty pumping, the blood backs up in your blood vessels causing fluid retention in lower extremities, abdomen, lungs, and kidneys. It is possible to have left-sided and right-sided congestive heart failure at the same time. CHF can be deadly if the main cause of the disease is not treated. Symptoms of congestive heart failure can be excess urination at night, chest pains, shortness of breath, swollen feet or legs, bloating, palpitations, Persistent coughing, or fatigue....

...great summarization post of congestive heart failure, my grandfather had congestive heart failure so I know first hand the effects it has on a person’s life. I thought it was very interesting that you pointed out one the first symptoms being not able to exercise without experiencing discomfort because not many individuals think of that as being a symptom they go to the go to symptoms like shortness of breath, coughing, and fatigue. In the beginning, before my grandfather was diagnosed with congestive heart failure he experienced difficulties lying down flat. Lying down flat causes parts of the lung to be in a more ¬¬¬dependent position. Another symptom to keep in mind for an individual with congestive heart failure is waking up with severe shortness of breath, and immediately needing to sit up to get their breath, and this is known as “paroxysmal nocturnal dyspnea”. The reason why there is a fluid build is when the heart’s output decreases; the body tries to compensate for it by releasing hormones that make the heart beat faster and stronger. This reflex though is only a short-term gain, and in the long run it really damages the heart’s function. The kidneys also sense the heart’s decrease in blood output, and they release hormones into the body, which cause sodium and...

...Warning Signs Of Potential Implant Failure Posted on February 23, 2016 by admin in Uncategorized How do you tell that your dental implant is failing? “It is failing if it is loose” is the answer most likely to be given by many people. However, while a loose implant is likely to fail, that isn’t the only symptom you should watch out for. Other signs that your implant isn’t likely to integrate or heal properly include: Discomfort Discomfort and pain are some of the first signs that something is wrong with your body. Therefore, pain and discomfort around your dental implant should send you to the dentist. The only exception is if your implant is a recent one, and you are experiencing post-surgical pain associated with healing. However, if you are already done with this early pain, and this is a new one, you may be dealing with something a bit more serious, such as peri-implantitis. This is a bacterial attack around the implant, and it is one of the most...

...The paper introduces the category of “architectural innovation” on the basis that seemingly minor changes to technology which may earlier be classified as an incremental innovation can have competitive consequences of a radical one. The key concept is the distinction between component knowledge and architectural knowledge. The paper argues that firms concentrate on refining components within a stable architecture established by a dominant design, and consequently, their “information-processing capabilities” are shaped by the existing architecture. While building upon component knowledge, their architectural knowledge is outmoded and made obsolete by architectural innovations. Their resulting inability to identify or understand new interactions between components has serious competitive consequences. The conceptual framework of the paper is clear and straightforward. The main argument is advanced in a logical manner, and supporting premises (such as the way organizations manage knowledge) are supported by prior literature. Within the boundaries of the paper’s assumptions, the argument is persuasive. Furthermore, the application to the photolithographic alignment (PA) equipment industry justifies the model. The trends in the industry suggest the conceptual framework is largely accurate. Nonetheless, the assumptions made limit the usefulness of the concept. Firstly, the analysis of firms’ information-processing is restricted to communication channels, information filtering...
