At the joining of non-removable plastic parts, methods such as friction welding, friction-stir ultra-sonic chemical joining, hot-plate welding use. Rotary which is one methods, generally used for filter parts water treatment devices. After rotating semi-melted agglomerations are formed in inner parts. To prevent accumulation, weld joint profile design was developed ABAQUS program previous study...

We propose a simple model for the behaviour of longterm investors on a stock market, consisting of three particles, which represent the current price of the stock and the opinion of the buyers, respectively sellers, about the right trading price. As time evolves, both groups of traders update their opinions with respect to the current price. The update speed is controled by a parameter γ, the p...

This paper studies dynamical properties of spatio-temporal pattern sequences (\synre chains") in associative networks of spiking neurons. Employing postsynaptic potentials with a nite rise-time, the replay speed of stored sequences can be controled by unspeci c background signals. In addition, the speed also depends on the number of co-activated sequences, but balanced inhibition can prevent th...

According IS01217 standard and metheds of performance test for general dis-placement air compressor of China, a m1crocomputor measurement and control system for performent test of compressor has been set up. All the test can be carried out without manual interference,it has been real1zed collecting and treating data automatically.Using some hardward and softward ~teps,the accurary and repetitio...

An annihilation gamma ray laser could be made by a cylinder of high density cold singlet Ps annihilating into a coherent gamma ray burst directed along the axis of the cylinder. Such a laser would have many important uses and prospects seem fair for making a 1J model in the immediate future. Higher intensity lasers that would be useful for controled fusion are envisioned, but involve so many or...

Materialization is a useful abstraction pattern that can be identified in many application settings. Intuitively, materialization is the relationship between a class of categories (e.g., models of cars) and a class of more concrete objects (e.g., individual cars). This paper gives a quasi-formal semantic definition of materialization in terms of the usual is-a and isof abstractions, and of a cl...
