We study regulatory networks of N genes giving rise to a vector expression profile v(t) in which each gene is Boolean; either on or off at any time. We require a network to produce a particular time sequence v(t) for t∈1,…,T and parameterize the complexity of such a genetic function by its duration T. We establish a number of new results regarding how functional complexity constrains genetic re...

Computing the minimal network (or minimal CSP) representation of a given set of constraints over the Point Algebra (PA) is a fundamental reasoning problem. In this paper we propose a new approach to solving this task which exploits the timegraph representation of a CSP over PA. A timegraph is a graph partitioned into a set of chains on which the search is supported by a metagraph data structure...

Organizations today face increasing pressures to integrate their processes across disparate divisions and functional units, in order to remove inefficiencies as well as to enhance manageability. Process integration involves two major types of changes to process structure: (1) synthesizing processes from separate but interdependent subprocesses, and (2) decomposing aggregate processes into disti...

Collaborative filtering (CF) has been one of the most important and popular recommendation methods, which aims at predicting users’ preferences (ratings) based on their past behaviors. Recently, various types side information beyond explicit ratings users give to items, such as social connections among metadata have introduced into CF shown be useful for improving performance. However, previous...

Will %R, stock market. Abstract— Investing in stock market is not an easy task. It needs careful decision making skills to maintain profit in the long run. Though many research works are available to guide the investors, they are not reliable and do not guaranty maximum profit possible. In this paper a fuzzy metagraph based stock market decision support system is proposed for short term investo...

With the increasing complexity of aircraft development programs, processes and their subsystems are continuously becoming complicated, leading to growing risks cost across entire life cycle. In this study, we proposed a model-based systems engineering approach support process modeling using multi-architecture language KARMA. Simultaneously, property verification hybrid automata simulation were ...
