Impairment Detection Technology
Impairment detection technology (IDT) refers to tools and systems designed to assess whether an individual is functionally impaired at a given moment, regardless of the cause. Unlike drug and alcohol tests that detect substances or their metabolites in the body, IDTs evaluate real-time cognitive or physical performance to identify active impairment. These systems are relevant where safety is critical, such as workplaces and law enforcement. IDTs do not identify the specific cause of impairment, such as drug use, fatigue, or illness, but instead detect behavioral or physiological markers like slowed reaction time, poor coordination, or eye movement abnormalities. Interest in IDT has increased as workplaces and law enforcement agencies address the limitations of traditional drug testing methods. The legalization of cannabis has underscored challenges associated with metabolite-based tests, which can yield positive results days after use, even when the individual is no longer im ...

Disability
Disability is the experience of any condition that makes it more difficult for a person to do certain activities or have equitable access within a given society. Disabilities may be Cognitive disability, cognitive, Developmental disability, developmental, Intellectual disability, intellectual, mental disorder#Disability, mental, physical disability, physical, Sense, sensory, or a combination of multiple factors. Disabilities can be Birth defect, present from birth or can be acquired during a person's lifetime. Historically, disabilities have only been recognized based on a narrow set of criteria—however, disabilities are not binary and can be present in unique characteristics depending on the individual. A disability may be readily visible, or Invisible disability, invisible in nature. The United Nations Convention on the Rights of Persons with Disabilities defines disability as including: Disabilities have been perceived differently throughout history, through a variety of ...

Machine Learning In Bioinformatics
Machine learning in bioinformatics is the application of machine learning algorithms to bioinformatics, including genomics, proteomics, microarrays, systems biology, evolution, and text mining. Prior to the emergence of machine learning, bioinformatics algorithms had to be programmed by hand; for problems such as protein structure prediction, this proved difficult. Machine learning techniques such as deep learning can feature learning, learn features of data sets rather than requiring the programmer to define them individually. The algorithm can further learn how to combine low-level Feature (machine learning), features into more abstract features, and so on. This multi-layered approach allows such systems to make sophisticated predictions when appropriately trained. These methods contrast with other computational biology approaches which, while exploiting existing datasets, do not allow the data to be interpreted and analyzed in unanticipated ways. Tasks Machine learning alg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining
Mining is the Resource extraction, extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agriculture, agricultural processes, or feasibly created Chemical synthesis, artificially in a laboratory or factory. Ores recovered by mining include Metal#Extraction, metals, coal, oil shale, gemstones, limestone, chalk mining, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even fossil water, water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final mine reclamation, reclamation or restoration of the land after the mine is closed. Mining ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Construction
Construction are processes involved in delivering buildings, infrastructure, industrial facilities, and associated activities through to the end of their life. It typically starts with planning, financing, and design that continues until the asset is built and ready for use. Construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or wikt:decommission, decommissioning. The construction industry contributes significantly to many countries' gross domestic products (Gross domestic product, GDP). Global expenditure on construction activities was about $4 trillion in 2012. In 2022, expenditure on the construction industry exceeded $11 trillion a year, equivalent to about 13 percent of global Gross domestic product, GDP. This spending was forecasted to rise to around $14.8 trillion in 2030. The construction industry promotes economic development and brings many non-monetary benefits to many cou ...

Road Safety In Europe
Road safety in Europe encompasses transportation safety among road users in Europe, including automobile accidents, pedestrian or cycling accidents, motor-coach accidents, and other incidents occurring within the European Union or within the European region of the World Health Organization (49 countries). Road traffic safety refers to the methods and measures used to prevent road users from being killed or seriously injured. In 2016, according to the World Health Organisation, road accidents were the eighth-biggest cause of death in the world; deadlier than both diarrhoeal diseases and tuberculosis. Not only is it important to consider road fatalities, but for every fatality on Europe's roads, it is estimated that 4 people will become permanently disabled, 10 will suffer Brain injuries, brain or spinal cord damage, 10 people will be seriously injured and 40 will have sustained minor injuries. On top of this, road accidents incur a large economic impact. In Europe alone, it is esti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Union
The European Union (EU) is a supranational union, supranational political union, political and economic union of Member state of the European Union, member states that are Geography of the European Union, located primarily in Europe. The union has a total area of and an estimated population of over 449million as of 2024. The EU is often described as a ''sui generis'' political entity combining characteristics of both a federation and a confederation. Containing 5.5% of the world population in 2023, EU member states generated a nominal gross domestic product (GDP) of around €17.935 trillion in 2024, accounting for approximately one sixth of global economic output. Its cornerstone, the European Union Customs Union, Customs Union, paved the way to establishing European Single Market, an internal single market based on standardised European Union law, legal framework and legislation that applies in all member states in those matters, and only those matters, where the states ...

Functional Near-infrared Spectroscopy
Functional near-infrared spectroscopy (fNIRS) is an optical brain monitoring technique which uses near-infrared spectroscopy for the purpose of functional neuroimaging. Using fNIRS, brain activity is measured by using near-infrared light to estimate cortical hemodynamic activity which occur in response to neural activity. Alongside EEG, fNIRS is one of the most common non-invasive neuroimaging techniques which can be used in portable contexts. The signal is often compared with the BOLD signal measured by fMRI and is capable of measuring changes both in oxy- and deoxyhemoglobin concentration, but can only measure from regions near the cortical surface. fNIRS may also be referred to as Optical Topography (OT) and is sometimes referred to simply as NIRS. Description fNIRS estimates the concentration of hemoglobin from changes in absorption of near infrared light. As light moves or propagates through the head, it is alternately scattered or absorbed by the tissue through which it t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blinking
Blinking is a bodily function; it is a semi-autonomic rapid closing of the eyelid. A single blink is determined by the forceful closing of the eyelid or inactivation of the levator palpebrae superioris and the activation of the palpebral portion of the orbicularis oculi, not the full open and close. It is an essential function of the eye that helps spread tears across and remove irritants from the surface of the cornea and conjunctiva. Blinking may have other functions since it occurs more often than necessary just to keep the eye lubricated. Researchers think blinking may help with disengagement of attention; following blink onset, cortical activity decreases in the dorsal network and increases in the default-mode network, associated with internal processing. Blink speed can be affected by elements such as fatigue, eye injury, medication, and disease. The blinking rate is determined by the "blinking center", but it can also be affected by external stimulus. Some animals, ...

Karolinska Sleepiness Scale
The Karolinska Sleepiness Scale (KSS) is a 9-point subjective scale used to assess a person's current level of sleepiness or alertness. It asks respondents to rate how sleepy or alert they feel at the moment (e.g. over the past 10 minutes) on a scale from 1 to 9. The scale is situational (a "state" measure), meaning it reflects sleepiness at a particular time and can change hour by hour. It was developed by Torbjörn Åkerstedt and Mats Gillberg at the Karolinska Institute in Sweden. Because of its simplicity and sensitivity to changes, KSS is used in sleep and fatigue research. History The KSS was introduced by Åkerstedt and Gillberg in 1990 as a unidimensional sleepiness rating scale. In their original work it was validated against brain electrical activity: higher KSS scores (more sleepiness) were strongly associated with increases in EEG alpha/theta power and slow eye movements. Over time, it became popular for tracking short-term changes in alertness during sleep studi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peer-reviewed Research
Peer review is the evaluation of work by one or more people with similar competencies as the producers of the work (peers). It functions as a form of self-regulation by qualified members of a profession within the relevant field. Peer review methods are used to maintain quality standards, improve performance, and provide credibility. In academia, scholarly peer review is often used to determine an academic paper's suitability for publication. Peer review can be categorized by the type and by the field or profession in which the activity occurs, e.g., medical peer review. It can also be used as a teaching tool to help students improve writing assignments. Henry Oldenburg (1619–1677) was a German-born British philosopher who is seen as the 'father' of modern scientific peer review. It developed over the following centuries with, for example, the journal ''Nature'' making it standard practice in 1973. The term "peer review" was first used in the early 1970s.

Psychomotor Learning
Psychomotor learning is the relationship between cognitive functions and physical movement. Psychomotor learning is demonstrated by physical skills such as movement, coordination, manipulation, dexterity, grace, strength, speed—actions which demonstrate the fine or gross motor skills, such as use of precision instruments or tools, and walking. Sports and dance are the richest realms of gross psychomotor skills. Behavioral examples include driving a car, throwing a ball, and playing a musical instrument. In psychomotor learning research, attention is given to the learning of coordinated activity involving the arms, hands, fingers, and feet, while verbal processes are not emphasized. Stages of psychomotor development According to Paul Fitts and Michael Posner's three-stage model, when learning psychomotor skills, individuals progress through the cognitive stages, the associative stage, and the autonomic stage. The cognitive stage is marked by awkward slow and choppy movem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alertness
Alertness is a state of active attention characterized by high sensory awareness. Someone who is alert is vigilant and promptly meets danger or emergency, or is quick to perceive and act. Alertness is a psychological and physiological state. Lack of alertness is a symptom of a number of conditions, including narcolepsy, attention deficit hyperactivity disorder, chronic fatigue syndrome, depression, Addison's disease, and sleep deprivation. Pronounced lack of alertness is an altered level of consciousness. States with low levels of alertness include drowsiness. The word is formed from "alert", which comes from the Italian (on the watch, literally: on the height; 1618). Wakefulness refers mainly to differences between the sleep and waking states; vigilance refers to sustained alertness and concentration. Both terms are sometimes used synonymously with alertness. Importance and difficulty People who have to be alert during their jobs, such as air traffic controllers or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
