Cognitive psychology is the study of human mental processes that occur within the mind. It looks at such internal processes such as, memory, perception and attention. It came about in the 1950’s as a result of the behaviourist approach being flawed; internal mental processes cannot be observed. Therefore, from this an alternative method of looking at the physiological side of the brain had to emerge. Cognitive neuroscience was then born to identify the neural mechanisms, which are responsible…

4. Recent development of forward osmosis: As mentioned above, FO technology is faced by several challenges that limit its application in large scale processes. The development of FO process can be governed by two major factors; the development of high-performing draw solutions and highly efficient FO membrane. 4.1. Draw solutes development: The draw solution has several factors that can affect FO performance. These factors mainly comprise of draw and feed solution osmotic pressures [61], draw…

a) According to the right-hand rule, the direction of the magnetic fields of the 3 wires are shown: We find the magnetic fields B1, B2 and B3: 퐵1=퐵2= 푢0 푖 = 푢0 푖 = 4∗3.14×10−7 ∗(3.65) =ퟒퟐ.ퟔퟔퟎ풖푻 2휋푟 2휋( 2푎) 2 ∗ 3.14 ∗( 2(0.0121)) 퐵3= 푢0 푖 = 푢0 푖 = 4∗3.14×10−7 ∗(3.65) =ퟐퟎ.ퟏퟏퟎ풖푻 2휋푟 2휋(3푎) 2 ∗ 3.14 ∗(3∗(0.0121)) The x components of the B1 and B2 cancel each other; therefore the net magnetic field will be downward and we have (the negative sign is because the direction is downward): 퐵=− 퐵1cos 45 +…

losses, smaller size, less maintenance, high reliability and the ability to operate without gearbox [33], [34]. The main aspect which distinguishes the Permanent Magnet Synchronous machine from other types of electrical machines is that the rotor magnetic flux is generated by permanent magnets, instead of being supplied by other external power sources as in DC machines and synchronous machines. Therefore, there are no rotor copper losses associated with this type of generator. Another main…

Introduction Brahmaputra River, the peculiar drainage pattern of large Southeast Asian rivers, reflects a complicated tectonic history of crustal deformation in the Himalaya and river re-organization. In general, the Himalayas are divided into three tectono-lithologic domains: the Lower Himalayas, the Higher Himalayas and the Tethys Himalayas (Amano and Taira, 1992); surprisingly this river flows through over these three domains (Fig.1). The mineral assemblages are correlated with these…

suspensions where the importance of Brownian forces is negligible (Pe≫1) can be expressed approximately as: η_r= (1-ϕ⁄ϕ_max )^(-1.82) ( 2 ) when multiplied by ϕ, the eq. ( 2 ) can be used to express the gradient of viscosity in terms of ∇ϕ and represent the flux attributed to the special variation of viscosity (N_η ) due to particle concentration gradients as follow: N_η=-K_η γ ̇ϕ^2 (a^2/η) dη/dϕ ∇ϕ ( 3 ) where K_η is a constant that must be determined experimentally. Once that both sources of…

The sun is the star we are orbiting, which gives us heat and more stuff. Of course, it is also potentially dangerous, it can cause skin cancer, solar winds, too much heat, and it will obviously end up destroying the earth in a few billion years. I am especially studying the solar winds, this is because I think that solar winds are more interesting than the others because they look as if they were more fun and had more things to talk about. The problem with solar winds is that they come to the…

Abstract—This paper aims at briefly discussing the various techniques used in tactile sensing and then compares them. Next, different types of commercial tactile sensors, along with suitable performance criteria for their comparison are discussed. Finally, currently existing commercial sensors are talked about in detail, including the leading manufacturers, their products and the description of their data sheet. Keywords— Artificial skin; Commercial; Sensors; Tactile. I. INTRODUCTION The word…

Introduction: Electricity, the base of modern civilization, is produced by electric generators, which are devices converting mechanical energy into electric energy [1-2]. As the need for energy is increasing, while the reserves of fossil fuels are dwindling, renewable energy sources gain importance. The renewable energy can be obtained using solar, geothermal, or wind turbine technologies. Significant research effort has been made in those areas. In recent years, wind energy has become the…
