The neuron set model based on dynamic neurons is under discussion. The “self-organizing memory” presented by circulating impulses is the principally new net feature. Such a “memory” is supposed to cause “intellectual” behavior of data-processing slot machine. As a rule the slot machine is referred to as a selfoperating process unit. The series of data-processing slot machines processing informa...

A novel biofilter containing organic, bentonite and halloysite media was applied for elimination of microbial pollutants from the air of an industrial hatchery. The concentrations of total mesophilic bacteria, Gram-negative bacteria, thermophilic actinomycetes, dust and bacterial endotoxin were determined in the air of hatchery during 2 months before installation of the biofilter, and during 6 ...

In this paper, we measured the levels of metals including Pb, Cr, Cd, Ni, Hg, Fe, and Cu in the inlet and outlet wastewater of hospitals. The samples were taken from wastewater in Bushehr׳s province hospitals, Iran. After the collection of samples, the concentration levels of metals were determined by using graphite furnace absorption spectrometer (AAS) method (Varian, SpectrAA 240, Australia)....

In this paper, we present new layouts for the multi-stage interconnection networks such as shuffle, banyan and baseline networks, that are suitable for photonic switching. In these new layouts, we decrease the number of crossovers of the stage links and crossovers between inlet-outlet of stages, which are known as the main bottleneck for the increase in switch capacity when it is realized for i...

Model-based control of the outlet temperature of a distributed solar collector eld is studied. An energy-based controller is derived using internal energy as a storage function and controlled variable. The controller relies on a distributed parameter nonlinear plant model and includes feedforward from the solar irradiation and inlet temperature. Stability of the closed loop is proved, and the m...

9 10 Ozone is a major pollutant of indoor air. Many studies have demonstrated the adverse health effect of 11 ozone and the byproducts generated as a result of ozone-initiated reactive chemistry in an indoor 12 environment. This study developed a Computational Fluid Dynamics (CFD) model to predict the ozone 13 distribution in an aircraft cabin. The model was used to simulate the distribution of...

Modern engines are cooled by complex air and liquid cooling systems that manage the flow of high temperature air, gases and coolants, and house critical thermal management components. Plastics, many supplied by DuPont, are playing an increasingly important role in key cooling system parts including thermostat and heater housings, outlet and inlet ports, valves, cross-overs, coolant pumps, water...

Airflow, contaminant concentration and temperature distribution in a two-bed hospital ward represented by simple model room with inlet and outlet vents, have been studied. Our work is concerned with the development and implementation of a practical and robust response surface based multi-objective optimization (MOP) scheme, with the aim of assisting hospital ward designers and managers /operato...

A thermal energy storage (TES) equipment utilizing phase change material (PCM) was designed and built. The PCM is sealed inside metal tubes and exchanges heat with process fluid flowing outside. The storage capacity characteristics of the system was analyzed based on date covering the inlet and outlet temperatures of the process fluid, volumetric flow rate of the process fluid, and temperature ...

due to the complex structure of the pressure-adjusting device used in most sprinklersfor variable irrigation, it is not possible to observe the flow behavior of the water passingthrough the flow field. in this paper, an integral three dimensional (3d) numerical modelbased on the structural characteristics of the fluidic sprinkler was constructed to simulatethe flow field distribution using comp...
