Streams, or infinite sequences, are infinite objects of a very simple type, yet they have a rich theory partly due to their ubiquity in mathematics and computer science. Stream differential equations are a coinductive method for specifying streams and stream operations, and their theory has been developed in many papers over the past two decades. In this paper we present a survey of the many re...

Most of current systems which play video data produced remotely in a real time manner transfer video packets without retransmission. However, corrupted packets can be retransmitted if the time of playing is delayed for the fixed amount time. This paper proposes a new reliable real time protocol, based on SSCOP for ATM networks, which retransmits the only corrupted packets which reach the receiv...

Laminar stagnation flow, axi-symmetrically yet obliquely impinging on a rotating circular cylinder, as well as its heat transfer is formulated as an exact solution of the Navier-Stokes equations. Rotational velocity of the cylinder is time-dependent while the surface transpiration is uniform and steady. The impinging stream is composed of a rotational axial flow superposed onto irrotational rad...

Headwater streams constitute the majority of watersheds in the United States and many in the midwest have been channelized for agricultural drainage. Public health implications of water chemistry and aquatic insects within channelized and unchannelized headwater streams have not been explored. We sampled water chemistry and aquatic insects in two channelized and two unchannelized headwater stre...

Cooktop burners are widely used nowadays. In cooktop burner design, nozzle efficiency and greenhouse gas(GHG) emissions mainly depend on heat transfer from the premixed flame to the impinging surface. This is a complicated issue depending on the individual and combined effects of various input combustion variables. Optimal operating conditions for sustainable burner design were rarely addressed...

The flow of a two-dimensional, plane turbulent jet impinging on a porous screen has been studied experimentally. It is shown how the overall flow structure depends on the porosity of the surface. For low screen porosity (β < 0.41, say), transverse wall jets can be formed on both sides of the screen and in extreme cases the axial momentum flux some way downstream of the screen falls to zero, so ...

The behaviour of a turbulent, axisymmetric, Boussinesq, vertical fountain that impinges on a horizontal plate a distance H from the fountain source is investigated. Images from Light Induced Fluorescence visualisation of the flow provide a clear picture of the internal structure of the impinging flow. The interaction between the impinging fountain and the plate results in a buoyant radial wall ...

The vnode interface has succeeded in supporting a wide range of file system implementations over its 6-year history. During that time it has also had to accommodate evolution in file system semantics, and in the relationship between the file system and the virtual memory system. The effects of this evolution have been less than elegant, and pressures for further evolution are mounting. The evol...

The concentrations and relative abundances of aquatic hyphomycete conidia in water were followed during a three-year study in two headwater streams at Coweeta Hydrologic Laboratory, North Carolina, using the membrane-filtration technique. After a one-year pretreatment period, one of the streams was enriched continuously with inorganic nutrients (N+P) for two years while the other stream served ...

The male sex of Tyloridasataraensis Kulkarni, 2014 is described based on specimens from the type locality. The distinguishing characters from its closest species Tyloridaventralis (Thorell, 1877) are detailed. An interesting behaviour of going underwater by T.sataraensis, on disturbance is recorded and tested for significance. The surveys have shown sighting of this species only to the perennia...
