Fusion welding and non-fusion welding Fusion welding is defined as a welding process of using heat by melting the base of metals in order to joint similar types of metals together. Filler is used in this welding process to provide bulk and strength to the welded joint [1]. Whereas non-fusion welding which is known also as solid state welding is a welding process where a particular amount of heat is applied to the joining metals which essentially below the melting point of the base metals that being

ARTIFICIAL VISION ABSTRACT: Blindness‚ the most severe form of visual impairment‚ deprives people the ability to move about unaided. It is the most feared ailment in the present world. The leading causes of chronic blindness include cataract‚ glaucoma‚ age-related macular degeneration‚ corneal opacities‚ diabetic retinopathy‚ trachoma‚ and eye conditions in children (e.g. caused by vitamin A deficiency). Artificial vision has been a challenging task for the opto bionics. But now‚ a limited form

Design of Steel Structures Prof. S.R.Satish Kumar and Prof. A.R.Santha Kumar 3.3 Welding and welded connections Welding is the process of joining two pieces of metal by creating a strong metallurgical bond between them by heating or pressure or both. It is distinguished from other forms of mechanical connections‚ such as riveting or bolting‚ which are formed by friction or mechanical interlocking. It is one of the oldest and reliable methods of joining. Welding offers many advantages over

nonequilibrium nonthermal plasma discharge. A quartz coaxial DBD tube (ID: 6 mm‚ OD: 12 mm) at 400-mbar xenon-filled pressure has been used in the experiment. A unipolar pulselike voltage up to a −6-kV peak working at 30 kHz has been applied to the discharge electrodes for the generation of microdischarges. A single discharge is observed per applied voltage pulse. Visual images of the discharge and electrical waveform confirm the diffused-type discharges. The knowledge obtained by dynamic processes of DBDs in the

ammonia‚ and hydrogen. The chemicals were all sealed inside a sterile array of glass flasks and flasks connected in a loop‚ with one flask half-full of liquid water and another flask containing a pair of electrodes. The liquid water was heated to induce evaporation‚ sparks were fired between the electrodes to simulate lightning through the atmosphere and water vapor‚ and then the atmosphere was cooled again so that the water could condense and trickle back into the first flask in a continuous cycle.

costs of drug treatment are about 1‚000 to 6‚000 dollars per patient per year1. Subthalamic deep brain stimulation (STN DBS) is a now commonly used method in which two electrodes are implanted in a patient’s subthalamic nuclei to decrease the motor symptoms and instabilities of the medication in PD. Usually there are two electrodes implanted‚ one in each hemisphere‚ even though PD occurs asymmetrically. That would make it logical to think that a unilateral implantation could be successful as well2

We are constantly hearing through television and other media sources that the job market for people trained in some sort of vocational skill is in very high demand. Media advertisements are encouraging students to consider a vocational skill when looking at their future

Abstract of SuperCapacitor Supercapacitor also known as electric double-layer capacitor (EDLC)‚electrochemical double layer capacitor‚ or ultracapacitors‚ is an electrochemical capacitor with relatively high energy density. Compared to conventional electrolytic capacitors the energy density is typically on the order of hundreds of times greater. In comparison with conventional batteries or fuel cells‚ EDLCs also have a much higher power density. In this article the use of super capacitors likes
