A horizontal distributor for biogas slurry application was proposed to explore the distribution performance through CFD analysis and verified by field test. The rheological properties of were analyzed at first, key parameters obtained next simulation. effects modes, inlet direction, outlets number on velocity flow mass rate horizonal investigated simulations. Results indicated that a non-Newton...

Pleural photodynamic therapy (PDT) has been used as an adjuvant treatment with lung-sparing surgical treatment for malignant pleural mesothelioma (MPM). In the current pleural PDT protocol, a moving fiber-based point source is used to deliver the light. The light fluences at multiple locations are monitored by several isotropic detectors placed in the pleural cavity. To improve the delivery of ...

In the past few years, Rapid Thermal Processes (RTP) have gained acceptance as mainstream technology for semi-conductors manufacturing. These processes are characterized by a single wafer processing with a very fast ramp heating of the silicon wafer (up to 200C/sec). The single wafer approach allows for faster wafer processing and better control of process parameters on the wafer. As feature si...

introduction: non-uniformity test is essentially the only required daily qc procedure in nuclear medicine practice. noise creates statistical variation or random error in a flood image. non-uniformity on the other hand does not have statistical nature and may be regarded as systemic error. the present methods of non-uniformity calculation do not distinguish between these two types of error. the...

Flash sintering is one of the newest techniques for sintering ceramics to near full density. It occurs in an appropriate combination of temperature and electric field. Temperature measurement is one of the most serious challenges in this process. In the present study, we tried to model a flash sintering process of 8YSZ and 3YSZ with finite element method to make an assessment for temperature di...

Random number generators are a small part of any computer simulation project. Yet they are the heart and the engine that drives the project. Often times software houses fail to understand the complexity involved in building a random number generator that will satisfy the project requirements and will be able to produce realistic results. Building a random number generator with a desirable perio...

In this paper a new method is introduced for generating uniform random numbers based on data oriented modeling. This modeling method of random variable is proposed in [1]. By using this method, uniform random variable is modeled with several data. Up to now, statisticians have used mathematical functions to model random variables. This approach conforms to human brain structure, in other words ...

background: the patterson-parker table was created in 1934 to determine mg-hr required to deliver the prescribed dose to the treatment area. these tables were created using the dosimetric data for 226ra that was determined in air and were utilized for dose calculations around implants with ra-equivalent radionuclides such as 137cs and 192ir. therefore, the differences of the tissue attenuation ...
