The paper presents the suitability of flyash-limephosphogypsum composite for its use in road pavements. The content of lime and phosphogypsum was varied from 2 to 10% and 0.5 to 4% respectively in flyash. The specimen prepared was cured for 7, 28, 56 and 90 days with burlap method of curing. Compaction tests were conducted on different flyash-lime-phosphogypsum composite and these results were ...

This paper proposes new techniques for efficiently parallelizing sliding window processing over data streams on a shared-nothing cluster of commodity hardware. Data streams are first partitioned on the fly via a continuous split stage that takes the query semantics into account in a way that respects the natural chunking (windowing) of the stream by the query. The split does not scale well enou...

Head-splitting fractures occur as a result of violent compression of the head against the glenoid; the head splits and the tuberosities may remain attached to the fragments or split and separate. Isolated humeral head-splitting fractures are rare injuries. Favorable results with osteosynthesis can be difficult to achieve because of the very proximal location of the head fracture and associated ...

Now the optimization strategies for power distribution are researched widely, and most of them are aiming to the optimal fuel economy and the driving cycle must be preknown. Thus if the actual driving condition deviates from the scheduled driving cycle, the effect of optimal results will be declined greatly. Therefore, the instantaneous optimization strategy carried out on-line is studied in th...

–A detailed investigation has done Redmud an Alluminium industrial waste product has done to study its feasibility for use in road constructions. In this study Redmud was stabilized with 2, 4, 6, 8,10and 12 percentages of lime and unconfined compressive strength, Split tensile strength and California bearing ratio tests were conducted at 1, 3, 7 and 28 days curing periods respectively. From the...

This paper presents a robot solution that allows to automatically reach a set of goals attributed to a robot. The challenge is to design autonomous robots assigned to perform missions without a predefined plan. We address the stochastic salesman problem where the goal is to visit a set of points of interest. A stochastic Road-Map is defined as a topological representation of an unstructured env...

Power-split continuously variable transmissions (CVTs) represent a promising technology to improve the fuel economy of high-power off-road vehicles such as construction and agricultural machines. There are capable of keeping the combustion engine running within the optimal range in terms of fuel economy and performance. Power-split CVTs are a very specific type of CVT because this kind of trans...

Large scale traffic congestion often stems from local traffic jam in single road or intersection. In this paper, macroscopic method was used to explore the formation and propagation of local traffic jam. It is found that (1) the propagation of traffic jam can be seen as the propagation of traffic signal parameters, that is, virtual split and virtual green time; (2) for a road with endogenous fl...

Searching for achieving an ambitious reduction in greenhouse gas emissions, the EU has set as a goal modal shift freight transport of 30% by rail near future. In this context, it is vital to use choice models road versus assess shippers’ acceptance actions promoting rail. This paper develops combined model jointly evaluating split and railway flows, addressed case when based on random utility a...
