The limited battery power available in the nodes of an ad hoc network makes it mandatory to reduce the energy expenditure. Thus, reducing the transmission distances between nodes and balancing the number of nodes among clusters are two effective approaches to battery power conservation in the design of green wireless ad hoc networks. To realise this goal, the concept of relative neighbourhood g...

Based on RNG k-ε turbulence model and dynamic grid technology, the internal fluid dynamics of splash lubrication three stage planetary gear reducer system is established. The distribution lubricating oil convective heat transfer characteristic in at different input rotational speeds are analyzed. results show that high speed condition, gas mixing volume degree atomization higher, coefficient to...

The process of compound selection and prioritization is crucial for both combinatorial chemistry (CBC) and high throughput screening (HTS). Compound libraries have to be screened for unwanted chemical structures, as well as for unwanted chemical properties. Property extrema can be eliminated by using property filters, in accordance with their actual distribution. Property distribution was exami...

Heat EXchangers (HEX) that are used in City Gate Station (CGS) systems are modeled numerically to recover the exhaust waste heat. It was tried to find the best viscous model to obtain results in accordance with experimental results and to change the heat exchanger design. This HEX is used for recovering heat from exhaust flue gas with a mixture of 40% water and 60% ethylene glycol as the coolin...

We quantify precisely the distribution of the output of a binary random number generator (RNG) after conditioning with a binary linear code generator matrix by showing the connection between the Walsh spectrum of the resulting random variable and the weight distribution of the code. Previously known bounds on the performance of linear binary codes as entropy extractors can be derived by conside...

Using the CFD model, a new ventilation system design will be found later taking into consideration the ventilation efficiency such as uniformity, stability, and suitability of environmental factors in a naturally ventilated broiler house. Because conducting a field experiment for the ventilation study presented so many difficulties, a reliable 3-dimentional computational fluid dynamics (CFD) mo...

Existing theoretical and simulation studies on georouting appear detached from experimental studies in real environments. We set up our test environment by using WSN430 wireless sensor nodes. To overcome the need for significant number of wireless nodes required to perform a realistic experiment in high density network, we introduce a novel approach emulation by using relatively small number of...

In the minimum energy broadcasting problem, each node adjusts its transmission power to minimize the total energy consumption while still guaranteeing the full coverage of the network. We consider both topology control and broadcast oriented protocols, for which all existing solutions require global network information. In this paper, we describe new localized protocols where nodes require only...

In a broadcasting problem, a message is sent from a source to all the other nodes in the network. Blind flooding is a classical mechanism for broadcasting, where each node retransmits received message to all its neighbors. Despite its important advantages, an increase in the number of requests or the network size or density produces communication overheads that limit the scalability of blind fl...

Experiments suggesting the existence of mind-matter interaction (MMI) effects on the outputs of random number generators (RNG) have been criticized based on the questionable assumption that MMI effects operate uniformly on each random bit, independent of the number of bits used per sample, the rate at which bits are generated, or the psychological conditions of the task. This ‘‘influence-per-bi...
