Layout of vertical turbine-generator units
Hydrotechnical Construction, 19821. Of the two examined schemes of laying out vertical units preference, in our opinion, should be given to scheme I (two-bearing with an umbrella-type generator) in view of a number of advantages of this scheme over scheme II (three-bearing with an overhead generator). 2.

Horizontal or vertical? Windows’ layout selection for shading devices optimization
Management of Environmental Quality: An International Journal, 2016Purpose The purpose of this paper is to constitute an efficient way to improve energy efficiency and occupants comfort in buildings through reduction of direct solar heat gains by exterior shading devices. The shadings orientation and layout depends on the building location and façade orientation, and influence consequently the windows layout.

Complex of machines for vertical layout in landscape architecture
Sel'skohozjajstvennaja tehnika: obsluzhivanie i remont (Agricultural Machinery: Service and Repair)The machine complex used for vertical alignment in landscape architecture, considering their influence on the efficiency of terrain transformation, is investigated. It is shown that achieving an optimal result in vertical alignment is possible with a rational selection of machines and their sequential application at various stages of the work.

Effect of Diagonal Layout on Efficiency of Twin Vertical Axis Turbine
Advanced Materials Research, 2013Vertical axis turbine is one of the tools used to extract tidal current energy. The purpose of this study is to show the effect of diagonal layout on the efficiency of vertical axis tidal turbine (VATT), using commercial software ANSYS CFX. For this purpose the angle between the incoming current flows is varied while the distance between the turbines ...

Optimal layouts of the tree of meshes with vertices on the perimeter of the bounding convex region
1984The lower bound for the minimal bisection width of the tree of meshes with respect to all vertices (w.r.t. all leaves) is determined in both cases. On the basis of these results the lower bounds of layout area with all vertices (leaves) on the perimeter of the bounding convex region, which coincide with upper bounds, are stated.

Layout considerations for improving the on-state performance of vertical SiC switching devices
2007 IEEE Power Electronics Specialists Conference, 2007The presented work shows simulated and experimental results of a method to improve the on-resistance of SiC Power devices by an optimized utilization of the drift zone. Mostly SiC devices have quite thin drift layers compared to silicon devices. Thus, the lateral dimensions of cell-like structures are much larger that the actual cell thickness in the ...

Challenges and opportunities of vertical FET devices using 3D circuit design layouts
2016 IEEE SOI-3D-Subthreshold Microelectronics Technology Unified Conference (S3S), 2016We report on vertical nanowire FET devices (VNWFETs) with a gate-all-around (GAA) configuration, which offer promising opportunities to enable further CMOS scaling and increased circuit layout efficiency. They allow up to 30% denser SRAM bitcells with improved read and write stability, smaller minimum operating voltages (Vmin), and lower standby ...

Frequent Itemset Mining in Vertical Layout with E-ACO Algorithm: In Super Market
2017 World Congress on Computing and Communication Technologies (WCCCT), 2017Association Rule Mining is a well-liked in data mining. Mostly Apriori algorithm is used for market basket analysis but this Apriori algorithm have few limitations like scan database again and again for finding frequent itemset, more access time. etc. This limitation is reduced by using vertical datasets in Eclat algorithm with ACO Technique is called ...

Study on flow characteristics in vertical slot fishways regarding slot layout optimization
Ecological Engineering, 2017Abstract Design of effective fishways is becoming increasingly important. This paper focuses on the effect of the angle of deflection (α) between small and large baffles in a vertical slot fishway (VSF). A reliable depth-averaged two-dimensional numerical model PCFLOW2D was used to perform simulations of various VSF configurations, including six ...
