Agent-based simulation of a financial market
This paper introduces an agent-based artificial financial market in which
heterogeneous agents trade one single asset through a realistic trading
mechanism for price formation. Agents are initially endowed with a finite
amount of cash and a given finite portfolio of assets. There is no
money-creation process; the total available cash is conserved in time. In each
period, agents make random buy and sell decisions that are constrained by
available resources, subject to clustering, and dependent on the volatility of
previous periods. The model herein proposed is able to reproduce the
leptokurtic shape of the probability density of log price returns and the
clustering of volatility. Implemented using extreme programming and
object-oriented technology, the simulator is a flexible computational
experimental facility that can find applications in both academic and
industrial research projects.Comment: 11 pages, 3 EPS figures, LaTEX. To be published in Physica A

Development of a Tridimensional Measuring Application For iPads
In today’s fast-paced distribution centers workers and management alike are constantly searching for the quickest and most efficient way to package items for distribution. Even with the advancement of app-oriented solutions to a variety of problems across many industries there is a distinct unmet need in distribution environments for an application capable of increasing the efficiency and accuracy of packaging items. This senior project focused on the development and testing of an application utilizing the Structure Three Dimensional Sensor and a 4th generation iPad to scan an object or group of objects to be packaged and determine the overall dimensions (length, width, & height) of the minimum sized package necessary to contain the objects. In cooperation with a Computer Science student, two Industrial Technology students developed multiple iterations and alternate methods of testing to determine and optimize the accuracy and functionality of the application. This project has been developed in coordination with the technical advisers Industrial Technology professor Javier de la Fuente (PhD) and Computer Science professor John Clements (PhD)
Web development productivity improvement through object-oriented application framework
Most of the commercial and industrial web applications are complex, difficult to implement, risky to maintain and requires deep understanding of the requirements for customization. As today's software market is more competitive, productivity has become a major concern in software development industry. The aim of this research is to design and develop an application framework for accelerating web development productivity through object-oriented technology. It allows customization, design reuse and automatic code generation to support productivity improvement as a breakthrough solution for the given problem. This research employed systematic
literature review (SLR) to identify the source of complexity and productivity factors. Agile development methodology was used to design the framework and it was validated by empirical data from two commercial projects. Results showed that object-oriented application framework (OOAF) has significant factors that affect productivity and dramatically improve higher productivity over traditional approach.
It has fulfilled the current needs by reducing complexities, development efforts and accelerates web development productivity. This research contributes in the area of software engineering, specifically in the field of software productivity improvement and software customization. These will lead to faster development time for software industries
Urban land use spectral using high resolution imagery and GIS approach in sustaining urban planning spatial databases
Remote sensing technology is useful for urban planning due to its capability in examining detailed spectral characteristic of urban land uses. This study attempts to review a relevant studied have been done in identified an appropriate spectral for urban land use using high resolution remote sensing images and GIS approach. The detailed spectral for urban land uses consist of residential, industrial and commercial in metropolitan and city center urban hierarchy will be discussed. The segmentation techniques through object oriented and the use of field measurement was highlighted, at once demonstrates the usability of such infrastructure to facilitate further progress of remote sensing and GIS application in urban planning in Malaysia. Finally, a discussion of the needs for further research is presented
Future Directions of Internet-based Control Systems
Recent advances in object-oriented, client/server technologies, and the Internet are supplying the technology enablers needed to provide a uniform information architecture that can be used to build software architecture allowing the inter-operation and integration of a wide set of diverse applications. Moreover the emerging standards start playing a significant role in the shaping of automation architectures in enterprises. The inclusion within a classical control system of Internet-related technologies and open distributed application concepts would give the present system compliance with current and future technological trends. At the present time, in the field of the industrial automation, real-time embedded control systems more and more need Internet connectivity for operations of remote plant administration, training, and supervisory activities. In this paper the state of the art in embedded control systems is presented within the field of industrial automation applications, and the technological scenario is discussed, followed by the trend for the evolution in process control systems. Guidelines for the design of innovative, thus competitive control systems are suggested. A case study is presented, outcome of an EC project in which one of the authors is involved, where a remote maintenance system is realized
Modeling the object-oriented software process: OPEN and the unified process
A short introduction to software process modeling is presented, particularly object-oriented modeling. Two major industrial process models are discussed: the OPEN model and the Unified Process model. In more detail, the quality assurance in the Unified Process tool (formally called Objectory) is reviewed
On the Identification of Agents in the Design of Production Control Systems
This paper describes a methodology that is being developed for designing and building agent-based systems for the domain of production control. In particular, this paper deals with the steps that are involved in identifying the agents and in specifying their responsibilities. The methodology aims to be usable by engineers who have a background in production control but who have no prior experience in agent technology. For this reason, the methodology needs to be very prescriptive with respect to the agent-related aspects of design
