In this expository paper we show how one can, in a uniform way, calculate the weight distributions of some well-known binary cyclic codes. The codes are related to certain families of curves, and the weight distributions are related to the distribution of the number of rational points on the curves.

Radio pulsar observations can be used to test aspects of general relativity from equivalence principle violations to binary orbital effects in the strong-field regime. This article summarizes the status of such tests at the start of the meeting, and describes two new tests made possible by recent observations of well-known binary pulsar systems.

In this paper, it is supposed that a project can be shown as a metagraph. The duration of activities are discrete random variables with known probability function, also one kind of consumable and constrained resource is required to execute each activity of the project.The objective of this paper is to maximize the probability of completion of stochastic metagraph before the due date of the proj...
