Niti

Niti can refer to:

  • Nickel titanium alloy or Nitinol
  • Shape memory alloy
  • NITI, a Bulgarian UAV
  • Niti, (Sanskrit: नीति), ethical theories in Hinduism
  • NITI Aayog, NITI Aayog (India)
  • Nickel titanium

    Nickel titanium, also known as nitinol (part of shape memory alloy), is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages e.g. Nitinol 55, Nitinol 60.

    Nitinol alloys exhibit two closely related and unique properties: shape memory effect (SME) and superelasticity (SE) (also called pseudoelasticity (PE)). Shape memory is the ability of nitinol to undergo deformation at one temperature, then recover its original, undeformed shape upon heating above its "transformation temperature". Superelasticity occurs at a narrow temperature range just above its transformation temperature; in this case, no heating is necessary to cause the undeformed shape to recover, and the material exhibits enormous elasticity, some 10-30 times that of ordinary metal.

    History

    The term nitinol is derived from its composition and its place of discovery: (Nickel Titanium-Naval Ordnance Laboratory). William J. Buehler along with Frederick Wang, discovered its properties during research at the Naval Ordnance Laboratory in 1959. William Buehler was attempting to make a better missile nose cone, which could resist fatigue, heat and the force of impact. Having found that a 1:1 alloy of nickel and titanium could do the job, in 1961 he presented a sample at a laboratory management meeting. The sample, folded up like an accordion, was passed around and flexed by the participants. One of them applied heat from his pipe lighter to the sample and, to everyone's surprise, the accordion-shaped strip stretched and took its previous shape.

    Armstechno NITI

    NITI (Bulgarian: НИТИ) is a very light-weight, stealthy remote-controlled Bulgarian unmanned aerial vehicle (UAV). It has been designed and constructed in 2006 by Armstechno Co. It mounts a color surveillance camera, a thermal vision camera, and has an option for adding chemical and radioactive contamination dosimeters. Its main tasks are air surveillance of contaminated areas, regions with possible terrorist group activity, artillery correction or observation of natural disaster-stricken areas. NITI has a maximum fuel capacity of 38 l. It also has a programmable autopilot system and GPS system.

    In 2011, NITI was evaluated by the Ministry of the Interior (MI) of Bulgaria, but the design was rejected due to numerous defects, an unreliable design and the inability of the aircraft to perform its tasks. The CEO of Armstechno Co. blamed the unsatisfactory performance of its UAVs on the poor training of MI operators.

    Changer Les Choses

    by: Nadiya

    J'aurais voulu changer les choses
    Changer le monde
    Avoir ce qu'il y a de mieux
    J'aurais voulu changer les choses
    Changer le monde
    Pour être encore un peu hereuse
    J'aurais voulu te parler et ne plus faire comme avant
    Attendre et espérer, on a perdu trop de temps
    Je n'avais plus les pieds sur terre, je ne croyais qu'en mes prières
    Mais les rêves qu'on a faits se sont tous envolés
    Je n'avais plus les pieds sur terre
    Je ne savais qu'être sincère
    Si seulement j'avais su
    Changer les choses
    Changer le monde
    Avoir ce qu'il y a de mieux
    J'aurais voulu changer les choses
    Changer le monde
    Pour être encore un peu heureuse
    On a brûlé notre amour en étant trop innocents
    Pour déjouer les mauvais tours à mon trop grand sentiment
    On n'avait pas les pieds sur terre, on ne voulait qu'être sincères
    J'y vois clair maintenant
    Changer les choses
    Changer le monde
    Avoir ce qu'il y a de mieux
    J'aurais voulu changer les choses
    Changer le monde
    Pour être encore un peu heureuse
    Changer les choses
    Changer le monde
    Avoir ce qu'il y a de mieux
    J'aurais voulu changer les choses
    Changer le monde
    Pour être encore un peu heureuse
    Changer de vie
    Changer aussi
    J'ai juste voulu changer d'histoire
    Encore y croire
    Changer de vie
    Changer aussi
    J'ai juste voulu changer de vie
    J'aurais voulu changer les choses
    Changer le monde
    Avoir ce qu'il y a de mieux
    J'aurais voulu changer les choses
    Changer le monde
    Pour être encore un peu heureuse
    Changer de vie
    Changer aussi
    J'ai juste voulu changer d'histoire
    Encore y croire
    Changer de vie
    Changer aussi
    J'ai juste voulu changer de vie
    Changer de vie
    Changer aussi
    J'ai juste voulu changer d'histoire
    Encore y croire
    Changer de vie
