1. Introduction For analyzing the mobility of diffusing molecules, single molecule experiments are well established. Experiments in ultra-thin liquid films revealed a heterogeneous behavior of diffusion [1], which could be explained by a layering of liquids at solid interfaces as reported in [2]. Consequently, a layer model with layer-dependent diffusion coefficient was developed. Layer transit...

in this research, shock wave motion, shock/boundary layer interaction, and flow separation in a transonic flow over a naca0012 airfoil were investigated experimentally. thirteen kulite sensors were utilized for measurement of pressure fluctuations over the airfoil. experiments were performed for angles of attack between -4 to 4 degrees and flow mach numbers of m= 0.39 to 0.82. the kulite sensor...

Over the past decade significant strides have been made in the development of pulse burst laser systems capable of producing high energy laser pulses at repetition rates in excess of 1 MHz. These unique laser systems are currently being used in experiments across a variety of fields ranging from traditional fluid dynamics to combustion to plasma physics. Described here is the use of one such sy...

The measured height of DNA molecules adsorbed on a mica substrate by scanning probe microscopy is always less than the theoretical diameter. In this paper we show that, when imaged in ambient conditions, the molecules are usually immersed in the salt layer used to adsorb them to the substrate. This layer distorts the measurement of DNA height and is the main source of error but not the only one...

This paper presents a parallel real-time crowd simulation method based on a hierarchical environmental model. A dynamical model of the complex environment should be constructed to simulate the state transition and propagation of individual motions. By modeling of a virtual environment where virtual crowds reside, we employ different parallel methods on a topological layer, a path layer and a pe...

As the size of samples grows, the accuracy of trained multi-layer perceptrons grows with some improvement in error rates. But we cannot use larger and larger samples, because computational complexity to train the multi-layer perceptrons becomes enormous and data overfitting problem can happen. This paper suggests an effective approach in determining a proper sample size for multi-layer perceptr...

A systematic method to identify key factors that control the synthesis of Physical Vapor Deposition (PVD)-based graphene on copper is necessary for engineering graphene growth. The statistical design-of-experiments method is employed and demonstrated in this work in order to fulfill the necessity. Full-factorial design-of-experiments are performed to examine the significance of the main effects...

Every layer of the mobile protocol stack contributes to next-generation advanced mobility management (MM). However, present MM architectures are largely single-layer specific and thus can hardly meet the simultaneous lowand high-level mobility support requirements. A co-operation of multiple layers would lead to a promising solution. Notably, there is an increasing interest to adopt cross-layer...

The paper presents a performance-oriented study of end-systems for high bandwidth multimedia communications. A 2-layer communication architecture is identiied, where the lower layer performs the segmentation/re-assembly of data packets sent/received over the network and the upper layer performs the multiplexing/demultiplexing functions and enforces`quality of service' (QOS) control on various d...
