In a time when the entire world is going through pandemic which can be curbed or substantially avoided and reduced by maintaining distance, it crucial for every individual to follow social distancing norms. However, challenging daunting task ensure safe distance all time. Thus Sixth Sense Jacket great way keep user mindful alert of their surrounding without actually being It not only but also d...

Carbon emissions and excessive power usage are addressed by applying thermoelectric cooling, which benefits from its ability to be portable, economical, reliable. However, a conventional air conditioner's coefficient of performance (COP) is much less due the sustained heat generated on module's hot side. This work presents novel idea utilizing nanofluid cooled radiator as an external cooling ja...

Waste heat recovery has been considered as an attractive technique to improve the overall energy utilization efficiency of internal combustion (IC) engines. In this paper, distinct from most past research work, a thermally driven refrigeration system based on combined organic Rankine and vapour compression cycles is proposed recover IC engines’ waste contained in cooling water. Based concept, l...

the sirri jacket offshore platform was designed and installed in persian gulf of iran in 1975 and has been in service since that time. the importance of offshore structure's stability and the failure of this kind of structure during an earthquake in different active zones revealed that earthquake loading has to be considered. in this paper, magnetorheological (mr) fluid dampers have been propos...

• Advanced thermal management technologies for motors in electric cars are reviewed. Air and liquid cooling methods stator, winding rotor were critically examined. Possible to enhance the heat conduction thoroughly evaluated. Pros cons of current studies presented, with suggestions future work. The development has well been regarded as a major solution tackling challenges carbon-neutrality face...

Fundamental to any ballistic armour standard is the reference projectile that is to be defeated. Typically, for certification, consistency of bullet geometry is assumed. Therefore, practical variations in bullet jacket dimensions can have far reaching consequences. Traditionally, internal dimensions have been analysed by physically sectioning bullets – an approach which rules out any subsequent...

Generalization of the well-known Walsh–Hadamard transform (WHT), namely center-weighted Hadamard transform (CWHT) and complex reverse-jacket transform (CRJT) have been proposed and their fast implementation and simple index generation algorithms have recently been reported. These transforms are of size 2 2 for integral values or , and defined in terms of binary radix representation of integers....

Heat transfer coefficients in a continuous oscillatory baffled crystallizer (COBC) with nominal internal diameter of 15 mm have been determined as function flow and conditions typically used under processing conditions. Residence time distribution measurements show near-plug high Peclet numbers on the order 100–1000 s, although there was significant oscillation damping longer COBC setups. Very ...

Diatoms have evolved a variety of colonial life forms in which cells are connected by organic threads, mucilage pads or silicate structures. In this study, we provide the first description of a novel strategy of colony formation among marine planktonic diatoms. Bacteriastrum jadranum forms loose but regular chains with distinct heterovalvate terminal cells. The colonial cells and their siliceou...

Recently, Lee and Hou (IEEE Signal Process Lett 13: 461-464, 2006) proposed one-dimensional and two-dimensional fast algorithms for block-wise inverse Jacket transforms (BIJTs). Their BIJTs are not real inverse Jacket transforms from mathematical point of view because their inverses do not satisfy the usual condition, i.e., the multiplication of a matrix with its inverse matrix is not equal to ...
