abstract. academic spin-offs are recognized as the main means of technology transfer, contribute to the commercialization of the results of academic research, leading to society wealth creation. academic spin-offs start with some major disadvantages related to their liability of newness, smallness and their university origination. it is been argued that academic spin-off need to strengthen thei...

Extended Abstract. Sampling is the process of selecting units (e.g., people, organizations) from a population of interest so that by studying the sample we may fairly generalize our results back to the population from which they were chosen. To draw a sample from the underlying population, a variety of sampling methods can be employed, individually or in combination. Cut-off sampling is a pr...

Fisher’s phenomenological renormalization method is used to calculate the mass gap and the correlation length of the O(N) nonlinear σ model on a semi-compact space S1 ×R2. This shows that the ultraviolet momentum cut-off does not conflict with the infrared cut-off along the S1 direction. The mass gap on S2 × R1 is also discussed. ∗e-mail address: [email protected] 1 The O(N) nonlinear σ (NLσ...

Based on geological information of the Fengman dam, the seepage flow of the dam is analyzed. There are many different affecting factors on seepage problem, for example: the effect of the parameter of concrete, cut-off wall, the permeability coefficient of cut-off wall, drainage hole and grout curtains etc. On the basis of the research, the seepage control mechanism and effectiveness of the seep...

In this paper we study the numerical passage from the spatially homogeneous Boltzmann equation without cut-off to the Fokker-Planck-Landau equation in the so-called grazing collision limit. To this aim we derive a Fourier spectral method for the non cut-off Boltzmann equation in the spirit of [21, 23]. We show that the kernel modes that define the spectral method have the correct grazing collis...

The frequency response of all oxide field-effect transistors with amorphous LaAlO3 on a crystalline SrTiO3 substrate is reported. The intrinsic cut-off frequencies of 4 lm gate-length devices are found to be approximately 17 MHz indicating that with gate length scaling gigahertz cut-off frequency is possible. The low cut-off frequency is primarily limited by the low effective mobility. The esti...

Urban atmospheric visibility is closely associated with our daily life, such as navigation and human health. In the traditional, visibility is measured by professionally trained people. Meters and technologies were proposed to replace the traditional measurement. Digital image processing technology is one of schemes to measuring visibility. Since the good visibility contains more detail data, t...
