We consider the problem of building probabilistic models that jointly model short natural language utterances and source code snippets. The aim is to bring together recent work on statistical modelling of source code and work on bimodal models of images and natural language. The resulting models are useful for a variety of tasks that involve natural language and source code. We demonstrate thei...

MACs (Message Authentication Codes) are widely adopted in communication systems to ensure data integrity and data origin authentication, e.g. CBC-MACs in the ISO standard 9797-1. However, all the current designs based on block cipher either suffer from birthday attacks or require long key sizes. In this paper, we focus on designing single keyed block cipher based MAC achieving beyond-birthday-b...

Purpose – The purpose of this paper is to provide an overview of structural design code development in Mexico, as an example of how code evolution has taken place in many countries, and to discuss the challenges faced in improving code compliance and reducing vulnerability. Design/methodology/approach – All building codes for Mexico City (1920-2004) and current codes in Mexico were analyzed and...

The objective of the current study is to develop a simple formula to estimate the fundamental vibration period of tall buildings for using in equivalent lateral force analysis specified in building codes. The method based on Sturm-Liouville differential equation is presented here for estimating the fundamental period of natural vibration. The resulting equation, based on the continuum represent...

Building Code is a legal document that provides a minimum level of safety and health for the constructions to make the public live in safe buildings. People recognize the importance of constructing the buildings in safe conditions, since the dawn of civilization. Many countries around the world were facing different kind of disasters such as fires, earthquakes, etc. These disasters made builder...
