LabWindows/CVI
LabWindows/CVI (CVI is short for C for Virtual Instrumentation) is an ANSI C programming environment for test and measurement developed by National Instruments. The program was originally released as LabWindows for DOS in 1987, but was soon revisioned (and renamed) for the Microsoft Windows platform. The current version of LabWindows/CVI (commonly referred to as CVI) is 2020. LabWindows/CVI uses the same libraries and data-acquisition modules as the better known National Instrument product LabVIEW and is thus highly compatible with it. LabWindows/CVI is targeted more at domain experts and scientists, and CVI more towards software engineers that are more comfortable with text-based linear languages such as C. Release history Starting with LabWindows/CVI 8.0, major versions are released around the first week of August, to coincide with the annual National Instruments conference NI Week, and followed by a bug-fix release the following February. In 2009, National Instruments st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cortical Visual Impairment
Cortical visual impairment (CVI) is a form of visual impairment that is caused by a brain problem rather than an eye problem. (The latter is sometimes termed "ocular visual impairment" when discussed in contrast to cortical visual impairment.) Some people have both CVI and a form of ocular visual impairment. CVI is also sometimes known as cortical blindness, although most people with CVI are not totally blind. The term neurological visual impairment (NVI) covers both CVI and total cortical blindness. Delayed visual maturation, another form of NVI, is similar to CVI, except the child's visual difficulties resolve in a few months. Though the vision of a person with CVI may change, it rarely if ever becomes totally normal. The major causes of CVI are as follows: asphyxia, hypoxia (a lack of sufficient oxygen in the body's blood cells), or ischemia (not enough blood supply to the brain), all of which may occur during the birth process; developmental brain defects; head injury; hydroce ...

Chemical Vapor Infiltration
Chemical vapour infiltration (CVI) is a ceramic engineering process whereby matrix material is infiltrated into fibrous preforms by the use of reactive gases at elevated temperature to form fiber-reinforced composites. The earliest use of CVI was the infiltration of fibrous alumina with chromium carbide. CVI can be applied to the production of carbon-carbon composites and ceramic-matrix composites. A similar technique is chemical vapour deposition (CVD), the main difference being that the deposition of CVD is on hot bulk surfaces, while CVI deposition is on porous substrates. Process During chemical vapour infiltration, the fibrous preform is supported on a porous metallic plate through which a mixture of carrier gas along with matrix material is passed at an elevated temperature. The preforms can be made using yarns or woven fabrics or they can be filament-wound or braided three-dimensional shapes. The infiltration takes place in a reactor which is connected to an effluent-t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chronic Venous Insufficiency
Chronic venous insufficiency (CVI) is a medical condition in which blood pools in the veins, straining the walls of the vein. The most common cause of CVI is superficial venous reflux which is a treatable condition. As functional venous valves are required to provide for efficient blood return from the lower extremities, this condition typically affects the legs. If the impaired vein function causes significant symptoms, such as swelling and ulcer formation, it is referred to as chronic venous disease. It is sometimes called ''chronic peripheral venous insufficiency'' and should not be confused with post-thrombotic syndrome in which the deep veins have been damaged by previous deep vein thrombosis. Most cases of CVI can be improved with treatments to the superficial venous system or stenting the deep system. Varicose veins for example can now be treated by local anesthetic endovenous surgery. Rates of CVI are higher in women than in men. Other risk factors include genetics, smok ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taelon
''Earth: Final Conflict'' is a science fiction television series based on ideas developed by Gene Roddenberry. The series was produced under the guidance of his widow, Majel Barrett-Roddenberry, who possessed notes kept by Roddenberry that would provide the conceptual basis for the series. It ran for five seasons between October 6, 1997, and May 20, 2002. Setting Early in the 21st century, a race of aliens, the Taelons (often referred to as "the Companions"), travel to Earth and take up residence in limited numbers. The Taelons possess highly advanced technologies, many of which they share with humanity, seemingly out of generosity and good will. As a result of these advances, disease, war and pollution are nearly eliminated within three years of their arrival. Despite this, some question whether the Taelons' motives are as benevolent as they appear, and a resistance movement forms to halt the Taelons' ever-growing influence on humanity. Development After the cancellation of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commercial Vehicle Inspection
Commercial Vehicle Inspection (CVI), is the enforcement of safety regulations and laws of commercial vehicles. Some U.S. state departments of transportation refer to it as CVE (Commercial Vehicle Enforcement). CVI enforcement can be done roadside by state troopers or at specific stations, sometimes called "weigh station A weigh station is a checkpoint along a highway to inspect vehicular weights and safety compliance criteria. Usually, trucks and commercial vehicles are subject to the inspection. Weigh stations are equipped with truck scales, some of which are ...s." Below are of some of the things that are checked for: *inadequate tires *brake linings that are oil soaked *cracked brake linings *brake linings with inadequate (worn) thickness *cracked frames *fuel leaks *disqualified drivers *overweight vehicles *oversize vehicles (vehicle dimensions) *hours-of-service (how long a driver has driven for) *driver qualifications *permit conditions *cargo securement *mechanical fitn ...

Stroke
A stroke is a medical condition in which poor blood flow to the brain causes cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than one or two hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. A hemorrhagic stroke may also be associated with a severe headache. The symptoms of a stroke can be permanent. Long-term complications may include pneumonia and loss of bladder control. The main risk factor for stroke is high blood pressure. Other risk factors include high blood cholesterol, tobacco smoking, obesity, diabetes mellitus, a previous TIA, end-st ...

Devi And Vrkis Feminines
Devī (; Sanskrit: देवी) is the Sanskrit word for ' goddess'; the masculine form is ''deva''. ''Devi'' and ''deva'' mean 'heavenly, divine, anything of excellence', and are also gender-specific terms for a deity in Hinduism. The concept and reverence for goddesses appears in the Vedas, which were composed around the 2nd millennium BCE. However, they do not play a vital role in that era. Goddesses such as Lakshmi, Parvati, Durga, Saraswati, Sita, Radha and Kali have continued to be revered in the modern era. The medieval era Puranas witness a major expansion in mythology and literature associated with Devi, with texts such as the Devi Mahatmya, wherein she manifests as the ultimate truth and supreme power. She has inspired the Shaktism tradition of Hinduism. Further, Devi and her primary form Parvati is viewed as central in the Hindu traditions of Shaktism and Shaivism. Etymology ''Devi'' and ''deva'' are Sanskrit terms found in Vedic literature around the 3rd mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Colloid Vibration Current
Colloid vibration current is an electroacoustic phenomenon that arises when ultrasound propagates through a fluid that contains ions and either solid particles or emulsion droplets. Dukhin, A.S. and Goetz, P.J"Characterization of liquids, nano- and micro- particulates and porous bodies using Ultrasound" Elsevier, 2017 The pressure gradient in an ultrasonic wave moves particles relative to the fluid. This motion disturbs the double layer that exists at the particle-fluid interface. The picture illustrates the mechanism of this distortion. Practically all particles in fluids carry a surface charge. This surface charge is screened with an equally charged diffuse layer; this structure is called the double layer. Ions of the diffuse layer are located in the fluid and can move with the fluid. Fluid motion relative to the particle drags these diffuse ions in the direction of one or the other of the particle's poles. The picture shows ions dragged towards the left hand pole. As a resu ...
