In this paper we introduce an approach to increase integration rate of elements of a quadrature voltage-controlled oscillator. Framework the approach we consider a heterostructure with special configuration. Several specific areas of the heterostructure should be doped by diffusion or ion implantation. Annealing of dopant and/or radiation defects should be optimized.

Keywords: quadrature voltage-controlled oscillator; optimization of manufacturing; analytical approach for modelling.

In this paper we introduce an approach to increase density of field-effect transistors framework a static comparator. Framework the approach we consider manufacturing the inverter in heterostructure with specific configuration. Several required areas of the heterostructure should be doped by diffusion or ion implantation. After that dopant and radiation defects should by annealed framework optimized scheme. We also consider an approach to decrease value of mismatch-induced stress in the considered heterostructure. We introduce an analytical approach to analyze mass and heat transport in heterostructures during manufacturing of integrated circuits with account mismatch-induced stress.

Essential oils of Cymbopogon narduswere distilled and their chemical composition examined. C.nardus oil famously known as volatile and aromatic citronella oil that extracted from the grass of C.nardus species and its grown for the commercial essential oils. These essential oils get more beneficial and getting high demand in the market especially for therapeutic industries, biological properties and also for commercial such as perfume, soap, food flavouring and repellent product. The aim of this research was to evaluate the oil chemical compound of C.nardus essential oil based on GC-MS data that obtained from C.nardus species by using Z-score technique. The work involved of selecting C.nardus oil samples that cultivated from Melaka and Pahang. The input was the abundances (%) of C.nardus oil compounds and the output was the analysis of chemical compounds for C.nardus oil. The input and output data were pre-processed as follow; data transformation by using Z-score technique. The result shows that the significant chemical compound that found in C.nardus species by using Z-score technique include citronellol and geraniol.

Keyword: C.nardus, citronella, Cymbopogon, Z-score technique, essential oils.

Compared with the classical fractal set, the Julia set of the generalized alternating system has stronger sensitivity to initial conditions. In this paper, a digital image encryption scheme based on generalized alternated Julia set is proposed. This encryption algorithm utilizes generalized alternated Julia set to generate the random key, and the key space of this scheme large enough. Since the generalized alternated Julia set can be generated with only six parameters, it can reduce the storage space greatly. At the same time, the generalized alternated Julia set has good sensitivity to initial conditions, which can improve the security of encryption as the initial key. In order to verify the security of this encryption scheme, some relevant performance indicators of this encryption scheme are analyzed, which show that all performance indicators meet the image encryption security performance test standards.
