Myanmar language and script are unique and complex. Up to our knowledge, considerable amount of work has not yet been done in describing Myanmar script using formal language theory. This paper presents manually constructed context free grammar (CFG) with “111” productions to describe the Myanmar Syllable Structure. We make our CFG in conformity with the properties of LL(1) grammar so that we ca...

Large-scale grammars are a prerequisite for parsing a great variety of sentences, but it is difficult to build such grammars by hand. Yet, it is possible to derive a context-free grammar(CFG) automatically from an existing large-scale, syntactically annotated corpus. While being seemingly a simple task at first sight, CFGs derived in such a fashion have hardly ever been applied to an existing s...

Control Flow Graph (CFG) is a compact representation of all executable paths of a program and it is central to most program analyses. Unfortunately, the direct use of a CFG has two major sources of imprecision: (a) the existence of infeasible paths, and (b) the merging of states along incoming edges of a control-flow merge. Addressing these two problems is the path-sensitivity issue, and it is ...

This research explores the impact of Context Free Grammars (CFG) and Parse Trees for construction of a Telugu Language Sentences. Based on the CFG here we derived the derivations for the respective strings. Later we constructed the Parser Trees for the above said strings. Finally we analysed whether the string is ambiguous or unambiguous. Here for analysis we considered the Large Scale Open Sou...

Vibratory installation of piles and casings can be extremely economical and therefore the contractors’ preferred method of pile driving. Compared to impact pile driving it also has the advantage of reduced noise pollution. Unfortunately, this installation method is still fraught with uncertainties. The foremost question is driveability and equally important is the question of bearing capacity o...

Six buildings were overturned in the town of Onagawa during the 2011 Great East Japan tsunami. This study investigates the possible failure mechanisms of building overturning during tsunami flow. The tsunami inundation depth and flow velocity at each overturned building were recalculated by using a tsunami numerical simulation and verified using a recorded video. The overturning moment is a res...

The results of an ongoing FEM parametric study are presented regarding the dependence of the resulting piled raft behavior under lateral load and combination of loads on pile diameter, pile length, arrangement of piles and raft thickness. Taguchi method with Analysis of Variance (ANOVA) was employed to calculate the contribution ratio of these factors on the lateral displacement of piled raft. ...

this research examines the behavior of soil-reinforced piles and applied loads based on the analytical method and by using the numerical results of flac3d software for comparison with the analytical results. the analysis was based on a method called virtual retaining wall, the following into consideration: an imaginary retaining wall that passes the footing edge the bearing capacity of footing ...

Many offshore structures are subjected to overturning moments due to wind load, wave pressure, and ship impacts. Also most of retaining walls are subjected to horizontal forces and bending moments, these forces are due to earth pressure. For foundations in such structures, usually a combination of vertical and batter piles is used. Little information is available in the literature about estimat...

Constructive methods for obtaining regular grammar counterparts for some sub-classes of context-free grammars (CFGs) have been investigated by many researchers. An important class of grammars for which this is always possible is the one-letter CFG. We show in this paper a new constructive method for transforming an arbitrary one-letter CFG to an equivalent regular expression of star-height 0 or...
