Flow Resistance Analysis for Lower Naesung Stream Considering Grain and Bedform Roughness

Analysis and Comparison of Load Flow Methods for Distribution Networks Considering Distributed Generation

Conventional passive distribution networks are changing to modern active distribution networks which are not radial. Conventional load flow methods should be modified for new distribution networks analysis. In modern distribution networks distributed generation (DG) units are embedded with conventional and/or renewable resources. DG units are generally modeled as PV or PQ nodes which inject ...

Isothermal Analysis of Elliptic Bore Journal Bearing Considering Isotropic Roughness

121804-6565-IJMME-IJENS © August 2012 IJENS I J E N S Abstract— Finite journal bearing of elliptic bore and circular bush is analyzed considering the isotropic roughness in the bearing surfaces. The angle of inclination of the major axis of the sleeve to the load line and the attitude angle are kept constant while evaluating all the performance parameters. Film shape due to the rough elliptic b...

Analysis of stream flow drought and deficiency in the west of Iran

River bedform inception by flow unsteadiness: A modal and nonmodal analysis.

River bedforms arise as a result of morphological instabilities of the stream-sediment interface. Dunes and antidunes constitute the most typical patterns, and their occurrence and dynamics are relevant for a number of engineering and environmental applications. Although flow variability is a typical feature of all rivers, the bedform-triggering morphological instabilities have generally been s...

Grain: a stream cipher for constrained environments

A new stream cipher, Grain, is proposed. The design targets hardware environments where gate count, power consumption and memory is very limited. It is based on two shift registers and a nonlinear filter function. The cipher has the additional feature that the speed can be increased at the expense of extra hardware. The key size is 80 bits and no attack faster than exhaustive key search has bee...
