Diagnostic
Diagnosis (: diagnoses) is the identification of the nature and cause of a certain phenomenon. Diagnosis is used in a lot of different academic discipline, disciplines, with variations in the use of logic, analytics, and experience, to determine "causality, cause and effect". In systems engineering and computer science, it is typically used to determine the causes of symptoms, mitigations, and solutions.

Molecular Diagnostics
Molecular diagnostics is a collection of techniques used to analyze biological markers in the genome and proteome, and how their cells express their genes as proteins, applying molecular biology to medical tests, medical testing. In medicine the technique is used to diagnose and monitor disease, detect risk, and decide which therapies will work best for individual patients, and in agricultural biosecurity similarly to monitor crop disease, crop- and livestock disease, estimate risk, and decide what quarantine measures must be taken. By analysing the specifics of the patient and their disease, molecular diagnostics offers the prospect of Personalized medicine, personalised medicine. These tests are useful in a range of medical specialties, including infectious disease, oncology, human leucocyte antigen typing (which investigates and predicts immune function), coagulation, and pharmacogenomicsthe genetic prediction of which drugs will work best. They overlap with clinical chemistr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Diagnosis
Medical diagnosis (abbreviated Dx, Dx, or Ds) is the process of determining which disease or condition explains a person's symptoms and signs. It is most often referred to as a diagnosis with the medical context being implicit. The information required for a diagnosis is typically collected from a history and physical examination of the person seeking medical care. Often, one or more diagnostic procedures, such as medical tests, are also done during the process. Sometimes the posthumous diagnosis is considered a kind of medical diagnosis. Diagnosis is often challenging because many signs and symptoms are nonspecific. For example, redness of the skin ( erythema), by itself, is a sign of many disorders and thus does not tell the healthcare professional what is wrong. Thus differential diagnosis, in which several possible explanations are compared and contrasted, must be performed. This involves the correlation of various pieces of information followed by the recognition and d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential Diagnosis
In healthcare, a differential diagnosis (DDx) is a method of analysis that distinguishes a particular disease or condition from others that present with similar clinical features. Differential diagnostic procedures are used by clinicians to diagnose the specific disease in a patient, or, at least, to consider any imminently life-threatening conditions. Often, each possible disease is called a differential diagnosis (e.g., acute bronchitis could be a differential diagnosis in the evaluation of a cough, even if the final diagnosis is common cold). More generally, a differential diagnostic procedure is a systematic diagnostic method used to identify the presence of a disease entity where multiple alternatives are possible. This method may employ algorithms, akin to the process of elimination, or at least a process of obtaining information that decreases the "probabilities" of candidate conditions to negligible levels, by using evidence such as symptoms, patient history, and medi ...

Unified Diagnostic Services
Unified Diagnostic Services (UDS) is a diagnostic communication protocol used in electronic control units (ECUs) within automotive electronics, which is specified in the ISO 14229-1. It is derived from ISO 14230-3 ( KWP2000) and the now obsolete ISO 15765-3 (Diagnostic Communication over Controller Area Network (DoCAN)). 'Unified' in this context means that it is an international and not a company-specific standard. By now this communication protocol is used in all new ECUs made by Tier 1 suppliers of original equipment manufacturer (OEM), and is incorporated into other standards, such as AUTOSAR. The ECUs in modern vehicles control nearly all functions, including electronic fuel injection (EFI), engine control, the transmission, anti-lock braking system, door locks, braking, window operation, and more. Diagnostic tools are able to contact all ECUs installed in a vehicle which have UDS services enabled. In contrast to the CAN bus protocol, which only uses the first and second ...

Computer-aided Diagnosis
Computer-aided detection (CADe), also called computer-aided diagnosis (CADx), are systems that assist doctors in the interpretation of medical imaging, medical images. Imaging techniques in X-ray, MRI, endoscopy, and Medical ultrasound, ultrasound diagnostics yield a great deal of information that the Radiology, radiologist or other medical professional has to analyze and evaluate comprehensively in a short time. CAD systems process digital images or videos for typical appearances and to highlight conspicuous sections, such as possible diseases, in order to offer input to support a decision taken by the professional. CAD also has potential future applications in digital pathology with the advent of whole-slide imaging and machine learning algorithms. So far its application has been limited to quantifying immunostaining but is also being investigated for the standard H&E stain. CAD is an interdisciplinary technology combining elements of artificial intelligence and computer visi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Diagnostics
Remote diagnostics is the act of diagnosing a given symptom, issue or problem from a distance. Instead of the subject being co-located with the person or system done diagnostics, with remote diagnostics the subjects can be separated by physical distance (e.g., Earth-Moon). Important information is exchanged either through wire or wireless. When limiting to systems, a general accepted definition is: "To improve reliability of vital or capital-intensive installations and reduce the maintenance costs by avoiding unplanned maintenance, by monitoring the condition of the system remotely." Process elements for remote diagnostics * Remotely monitor selected vital system parameters * Analysis of data to detect trends * Comparison with known or expected behavior data * After detected performance degradation, predict the failure moment by extrapolation * Order parts and/or plan maintenance, to be executed when really necessary, but in time to prevent a failure or stop Typical uses * Medica ...

Hickam's Dictum
Hickam's dictum is a medical principle that a patient's symptoms could be caused by several diseases. It is a counterargument to misapplying Occam's razor in the medical profession. A common version of Hickam's dictum states: "A man can have as many diseases as he damn well pleases." The principle is attributed to an apocryphal physician named Hickam, possibly John Bamber Hickam, MD. When he began saying this is uncertain. Occam's razor is frequently misinterpreted to mean that the simplest explanation is the most likely. Applying this in health care, it purports that diagnosticians should assume a single cause for multiple symptoms. Hickam's dictum admits multiple causes can produce the result confronting the diagnostician. John Hickam, MD In 1946, John Bamber Hickam was a housestaff member in medicine at Grady Memorial Hospital in Atlanta, Georgia. Later, in the 1950s, he was a faculty member at Duke University in Durham, North Carolina. He subsequently was chairman of medicine ...

Fault Tree Analysis
Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event rates of a safety accident or a particular system level (functional) failure. FTA is used in the aerospace, nuclear power, chemical and process, pharmaceutical, petrochemical and other high-hazard industries; but is also used in fields as diverse as risk factor identification relating to social service system failure. FTA is also used in software engineering for debugging purposes and is closely related to cause-elimination technique used to detect bugs. In aerospace, the more general term "system failure condition" is used for the "undesired state" / top event of the fault tree. These conditions are classified by the severity of their effects. The most severe conditi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RPR Problem Diagnosis
Rapid problem resolution diagnosis (or RPR diagnosis) is a method of problem diagnosis designed to determine the root cause of IT problems. History The method was originally developed by Advance7 in 1990 as Advanced Network Troubleshooting, with the first fully documented version produced in 1995. Early versions included problem management guidance but this was removed over time as the method became more closely aligned to ITIL, and the method name was changed to Rapid Problem Resolution (RPR). RPR is now focused on Problem Diagnosis based on Root Cause Identification. Due to the highly practical nature of the Supporting Techniques and the ever changing IT landscape, Advance7 continues to develop RPR to keep it relevant to current IT environments. Until November 2007 Advance7 made the RPR material available to its employees only, although a limited number of other IT professionals had been trained in the use of the method. In late 2007 the company announced its intention to mak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retrospective Diagnosis
A retrospective diagnosis (also retrodiagnosis or posthumous diagnosis) is the practice of identifying an illness after the death of the patient (sometimes a historical figure) using modern knowledge, methods and disease classifications. Alternatively, it can be the more general attempt to give a modern name to an ancient and ill-defined scourge or plague. Historical research Retrospective diagnosis is practised by medical historians, general historians and the media with varying degrees of scholarship. At its worst it may become "little more than a game, with ill-defined rules and little academic credibility". The process often requires "translating between linguistic and conceptual worlds separated by several centuries", and assumes our modern disease concepts and categories are privileged. Crude attempts at retrospective diagnosis fail to be sensitive to historical context, may treat historical and religious records as scientific evidence, or ascribe pathology to behaviours tha ...

Fault Management
In network management, fault management is the set of functions that detect, isolate, and correct malfunctions in a telecommunications network, compensate for environmental changes, and include maintaining and examining error logs, accepting and acting on error detection notifications, tracing and identifying faults, carrying out sequences of diagnostics tests, correcting faults, reporting error conditions, and localizing and tracing faults by examining and manipulating database information. When a fault or event occurs, a network component will often send a notification to the network operator using a protocol such as SNMP. An alarm is a persistent indication of a fault that clears only when the triggering condition has been resolved. A current list of problems occurring on the network component is often kept in the form of an active alarm list such as is defined in RFC 3877, the Alarm MIB. A list of cleared faults is also maintained by most network management systems. Fault m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
