The application of the new structure to the complex field of THz receivers requires the availability of an analytical model, reliable and able to highlight the dependence on the parameters of the physical structure. We present a model of the rectification capability of the double barrier Terahertz radiation (THz) detector, a CMOS compatible structurer. The model is based on the hydrodynamic sem...

Since portable systems and processing power applications demand efficient power consumption, this paper deals with the development of an analytical model based on the on-resistance effect of MOS switches to design a silicon-based charge-pump voltage generator (VG). This model that is developed for adding design parameters under the designer’s control is a useful design tool to quickly estimate ...

We construct a simple analytical model to study the effects of cosmic strings on the microwave background radiation. Our model is based on counting random multiple impulses inflicted on photon trajectories by the string network between the time of recombination and today. We construct the temperature auto-correlation function and use it to obtain the effective power spectrum index n, the rms-qu...

The concept of a “localization policy” (local content) is a tool often used to support industrial growth with the domestic market. The localization policy has supported the heavy electro-mechanical industry in Taiwan for years, with bolstered research and development (R&D) and technological transfer approaches. The industry now can develop products to compete with international brands. The entr...

Large scale scientiic projects generate and use huge amounts of data. For example, the NASA EOSDIS project is expected to archive one petabyte per year of raw satellite data. This data is made automatically available for processing into higher level data products and for dissemination to the sci-entiic community. Such large volumes of data can only be stored in robotic storage libraries (RSLs) ...

The ESP game belongs to the genre called Games with a Purpose (GWAP), which leverage people’s desire to be entertained and also outsource certain steps of the computational process to humans. The games have shown promise in solving a variety of problems, which computer computation has been unable to resolve completely thus far. In this study, we consider generalized ESP games with two objective...

This paper elaborates on a sustainability model for Language Resources, both at a descriptive and analytical level. The first part, devoted to the descriptive model, elaborates on the definition of this concept both from a general point of view and from the Human Language Technology and Language Resources perspective. The paper also intends to list an exhaustive number of factors that have an i...

Streaming over TCP has become popular as demonstrated by the example of YouTube. To cope with variability in data throughput, streaming applications typically implement buffers. Yet, for improving the quality of user experience, it is critical to dimension buffers and initial buffering delays appropriately. In this paper, we develop an analytical framework that describes the dimensioning of app...

Previous multifractal spectrum theories can only reflect that an object is multifractal and few explicit expressions of f(α) can be obtained for the practical application of nonlinearity measure. In this paper, an analytical model for multifractal systems is developed by combining and improving the Jake model, Tyler fractal model and Gompertz curve, which allows one to obtain explicit expressio...

Coded Video Tra c Hai Liu, Nirwan Ansari, and Yun-Qing Shi Abstract: Self-similar processes, modulated according to the MPEG frame structure, are proposed to capture both the SRD (short range dependency) and LRD (long range dependency) of MPEG video tra c. Introduction: Tra c generated by video applications is increasingly cramming existing networks, and it is thus essential to accurately chara...
