  • Abstract In this paper we demonstrate how Lyapunov-Krasovskii functionals can be used to obtain exponential bounds for the solutions of time-invariant linear delay systems. Keywords: time delay system, exponential estimate, Lyapunov-Krasovskii functional. The objective of this note is to describe a systematic procedure of constructing quadratic Lyapunov functionals for (exponentially) stable linear delay systems in order to obtain exponential estimates for their solutions.

  • This paper describes novel and practical Japanese parsers that uses decision trees. First, we construct a single decision tree to estimate modification probabilities; how one phrase tends to modify another. Next, we introduce a boosting algorithm in which several decision trees are constructed and then combined for probability estimation. The two constructed parsers are evaluated by using the EDR Japanese annotated corpus. The single-tree method outperforms the conventional .Japanese stochastic methods by 4%. ...

  • A superstructure can be thought of as the conduit which carries a roadway over a crossing. Like any other bridge component, the superstructure is comprised of many elements. In the bridge design profession, no other component elicits so much discussion, and even downright controversy, as to the type of elements to be utilized in construction. The structural and geometric complexities of the superstructure component make it one of the most challenging design problems in a bridge engineering project....

  • A soft ground condition exists whenever construction loads a cohesive foundation soil beyond its preconsolidation stress, as often occurs with saturated clays and silts having SPT blow counts that are near zero. The paper recommends testing programs, testing methods and data interpretation techniques for developing design parameters for settlement and stability analyses. It hopes to move the state-of-practice closer to the state-of-the-art and thus is intended for geotechnical practitioners and teachers rather than researchers.

  • It was just a few decades ago, in the 1950s, that modern project management was first seen as an individual subject within the area of economic sciences. Centuries back, so-called “projects” were finished successfully, e.g. the building of the aqueducts in Roman times or the construction of the Great Wall in China, but these projects were managed more on an ad-hoc basis mostly using informal techniques and tools.

  • By combining small tasks and including a detailed description of the task it will be possible to simplify the schedule merely by reducing the number of tasks in the Gantt. The task effort estimates will be apportioned to individual roles and resources in the next task. Record all assumptions supporting the estimate in the task description. This is very important because it will enable you to recreate and substantiate the estimate. It will also ensure that you have thoroughly thoughout what is to be done, and that it is communicated clearly to the Team.

  • In any discussion of a project budget, top management usually begins by asking, “What should this project cost, and is that reasonable?” If the project is optional, the decision to proceed should be based on an estimate of expenses versus future profits. For example, Will the effort reduce operating expenses? Is the project really necessary? The only way to answer these questions is to identify the true cost of the project. Your estimate must include labor expense—the cost of paying members of your project team.

  • Scientists, engineers and the like are a strange lot. Unperturbed by societal norms, they direct their energies to finding better alternatives to existing theories and concocting solutions to unsolved problems. Driven by an insatiable curiosity, they record their observations and crunch the numbers. This tome is about the science of crunching. It’s about digging out something of value from the detritus that others tend to leave behind. The described approaches involve constructing models to process the available data.
