ions, and that communication endpoints must not be tied to threads.I conclude that execution, protection, and modularity are orthogonal and therefore an operating systemshould provide support for modules independent of threads and protection domains. Lipto supportsmodularity through the abstraction of a module, which is the unit of composability and configurability. Amodule/obje...

In this paper we present our participation at TAC 2009 AESOP (Automatically Evaluating Summaries Of Peers) task. We make use of a statistical model for evaluation metric correlating to Overall Responsiveness and a nugget-based pyramid model for correlating to the Pyramid manual metric of TAC 2009. We also present the performance of our three submitted runs as per the official TAC 2009 evaluatio...

to determine the droplet characteristics of agricultural spray nozzles through water sensitive paper (wsp), the non-circular and overlapped spots appearing on the water sensitive paper surfaces are eliminated. in the conventional approach, the procedure is done according to the subjective self determined estimation of the operator. the objective of this study was to develop a practical alternat...

Waterlogging reduces the yield of food crops. Tolerance to waterlogging could vary between and within species. This study aimed to quantify tolerance to soil waterlogging in two divergent genotypes of pea (Pisum sativum), two of lentil (Lens culinaris) and a grasspea (Lathyrus sativus) control at germination and during vegetative growth. Following germination, seeds were grown for 14 days in so...

A methodological framework for assessing accuracy of the GDEM product is described using four small case studies in areas of variable relief and forect canopy (Booschord in the Netherlands, Calabria in Italy, Fishcamp in USA and Zlatibor in Serbia). Focus is put on evaluating the true accuracy of ASTER GDEM using LiDAR data aggregated to 30 m resolution. Three aspects of accuracy have been eval...

Different methods have been applied to refine various characteristics of the zone (or nugget) obtained by friction stir welding (FSW). In the current research, joining components are vibrated normal to the weld line during FSW to refine the zone microstructure. This process is described as friction stir vibration welding (FSVW). The effect of FSVW on mechanical properties, corrosion behavior, a...

Current blast furnace technology is a two-stage ironmaking process that requires that iron ore concentrate first be formed into pellets, fired at 1260°C, cooled, transported to the blast furnace, and then re-heated to approximately 1500°C to produce pig iron. This heating, cooling, and then reheating wastes a great deal of energy, which would be saved if the ironmaking process had only a single...
