One of the issues discussed in economy is the socioeconomic inequality in the society. Income mobility is another measure which indicates the degree of inequality of opportunity in a society. The extent of income mobility depends on socio-economic status of the individuals. Different socio-economic status leads to further inequality and increases inequality of opportunity. Such inequalities l...

CdSe nanoparticles have been solution deposited and thermally processed into thin film transistor channels, demonstrating for the first time that an inorganic semiconductor can be printed. A peak field effect mobility of 2.05 cmVAs 1 was observed for a device processed at 350 'C. The highest ON/OFF ratio, found in a different device, was 8.6x10 3 for a 10 to -10 V gate sweep at a drain-source v...

Data collection is an important procedure of ocean monitoring systems. Due to limited bandwidth and extreme high cost of satellite communication, the majority of data is unable to transmit via satellites. For the moment, there are no efficient data collection methods provided for data collection in underwater sensor networks. After collecting and analyzing GPS data of 40 ships for two months, w...

High-speed internet has boosted clients’ traffic needs. Content caching on mobile edge computing (MEC) servers reduces and latency. Caching with MEC faces difficulties such as user mobility, limited storage, varying preferences, rising video streaming The current content techniques consider mobility popularity to improve the experience. However, no present solution addresses preferences affecti...

a theoretical solution is presented for the forced convection heat transfer of a viscoelastic fluid obeying the giesekus constitutive equation in a concentric annulus under steady state, laminar, and purely tangential flow. a relative rotational motion exists between the inner and the outer cylinders, which induces the flow. a constant temperature was set in both cylinders, in this study. the f...

mobile-ad-hoc-networks (manets) are self-configuring networks of mobile nodes, which communicate through wireless links. the infrastructure of a mobile ad hoc network (manet) has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. the main issues in manets include the mobility of the network nodes, the scarcity of computati...

are a subset of MANETs in which vehicles are considered as network clients. These networks have been created to communicate between vehicles and traffic control on the roads. have similar features to MANETs and their main special property is the high-speed node mobility which makes a quick change of the network. The rapid change of network topology is a major challenge in routing. One of the we...

Marine protected areas (MPAs) are promoted as a tool to protect overfished stocks and increase fishery yields. Previous models suggested that adult mobility modified effects of MPAs by reducing densities of fish inside reserves, but increasing yields (i.e., increasing densities outside of MPAs). Empirical studies contradicted this prediction: as mobility increased, the relative density of fishe...
