The aim of this thesis work was to design a power amplifier for WiMAX applications at 3.5GHz based on cheap Si-LDMOS technology and to analyze the behavior of the design regarding nonlinear distortions and memory effects. A MW6S004NT1 Si-LDMOS RF high power transistor, from Freescale, with an ADS MET model was used in the process. This transistor is specified for Class A-AB base station applica...

The non-ideal behavior of aluminized explosives significantly affects the characteristics underwater explosion shockwaves, rendering classical model for shockwaves difficult to apply. In this paper, we analyze shockwave a new generation and propose explosive incorporating parameter correction function controlled by Al/O ratio. First, conducted tank experiments obtain four groups ratios paramete...

Ohmic and Schottky contacts are playing a major role in the field of ZnO based electronics device fabrication. It is seen that several works have been reported on metallization scheme, contacts with this semiconducting material. But, the thickness of semiconducting material and the choosing of substrate still remain imperfect and inefficient for advanced IC technology. To estimate contact resis...

Current methods for generating kinetic data can be categorized as either sampling steady-state conditions in flow or generating timeseries data in batch.[1] The latter method has proven particularly useful in identifying complex kinetic mechanisms.[2] Unfortunately, both of these techniques have significant limitations. While continuous flow experiments, especially in microreactors, have advant...

So far, a general model for the explanation of non-linear shunts and edge currents, often showing ideality factors n > 2, has been missing. Non-linear shunts like scratches and edge currents are the major source of the recombination current of industrial crystalline silicon solar cells. Moreover, the reverse current of such cells behaves always linear or even superlinear instead of saturation-t...

Land-use systems are characterized by complex interactions between human decision-makers and theirrights environment. Mismatches the scale of drivers impacts decisionspotentially threaten public rights as a whole. The research is normative legal using statute,case, conceptual approaches. results show that land for management can be used thepurposes conducting their duties or business, its use t...

CdSe nanostructures were synthesized by using green chemical route as starch was used as capping agent. XRD, HR-TEM, SEAD, UV and PL studies were made for structural and optical properties of the prepared sample. Film morphology and the thickness measurement of n-CdSe were carried out with AFM analysis. I-V characteristics curve of this junction confirmed the formation of Schottky contact betwe...
