LTE femtocells have been commonly deployed by network operators to increase network capacity and offload mobile data traffic from macrocells. A User Equipment (UE) camped on femtocells has the benefits of higher transmission rate and longer battery life due to its proximity to the base stations. However, various user mobility behaviors may incur frequent signaling overhead and degrade femtocell offloading...
This paper presents a novel approach, based on static analysis, to detect format string vulnerabilities in C programs. Format string vulnerability is viewed as a finite state safety property. The analysis is expressed as a system of constraint describing how the safety state at one program point is related to the state at adjacent program points. Our analysis is inter-procedurally flow sensitive and...
Electromagnetism drive is launcher which utilizes magnetic traveling wave produced by impulse or alternating current to drive projectiles with coil or magnetic material, essentially is a linear electric motor. The heat wasting affect coil gun's efficiency and capability, high temperature of driving coil will reduce its life, indeed burnout coil, and when enhancing firing rate, we need calculate effect...
Frequency of currents, material properties and physical shapes can influence the inductance. Especially for the transient current and linear medium, the current density may vary greatly to change the inductance. Based on the analysis of inductance calculation, a transformer model is introduced to illustrate the contributions of parameters to inductances. Numerical experiments are given to verify the...
Near infrared spectroscopy (NIRS) combined with partial least squares (PLS) was applied to establish model for quantitative analysis of the Polysaccharide in Irpex lacteus Fr. mycelia. Savitzky-Golay smoothing, First derivative, second derivative, fast Fourier transform (FFT) and standard normal variate (SNV) transformation methods were applied to preprocess NIRS. The efficacious spectral regions...
The present stage, effectively upgrading the customer value has become the most important means in market competition for enterprises, and increasing customer value needs to take a series of reasonable and feasible measures. Based on overview of the theories of customer value, customer satisfaction and marketing measures theory, this paper more comprehensively discusses the impact mechanism of the...
The Earth has been becoming a global village by interconnected internet; more and more enterprises recognize important roles of the internet for business development. In the context of people's focus from the internet needs to the internet value, if enterprises want to have higher competitive position, it is necessary to create more value for customers. Most studies focus on the level of the internet...
This paper presents a new method to generate test cased based on the Object Oriented Net (OON) model, notated with Z schemas. We can be benefited from this method in that: (1) Picturing the whole system while generating the test by the algorithm at the same time; (2) Instructing coding by the extended model.
