Taking Software Requirements Creation from Folklore to Analysis
Larry Berstein, Industry Research Professor, Stevens Institute of Technology, writes: "The performance of new systems capabilities for government agencies and industry are often examined using simulators. The simulators provide insight into how the new capabilities will perform. The simulators shed little light on reliability, complexity and other software engineering aspects of the proposed changes. The correlation between the complexities of the proposed capabilities with that of an earlier system can be used to bound the trustworthiness, possible schedule and potential costs for implementing the new capability. I call this the Lambda Protocol. It combines software reliability with software sizing theory. With performance, reliability, schedule and cost-estimates in hand, system and software engineers can make essential engineering tradeoffs as they set a course of action."

On The Emerging Future of Complexity Sciences
Offering a meta model that roadmaps the future, Kemal A. Delix, a lab scientist with Hewlett-Packard, and Ralph Dum, a physicist with the European Commission, say that complexity research will never become a single, encompassing theory-of-everything, or an independent discipline. It will thrive at the border between disciplines and in particular by interacting with engineering (thus approaching the Œscience of the artificial¹ that Herbert Simon was promoting) and it will surely create several seed technologies.

Issue 11 (March 21 - March 27, 2006) :
On the Realizability of Quantum Computers

WHY YOU SHOULD CHOOSE MATH IN HIGH SCHOOL
An article by Espen Andersen of the Norwegian School of Management encourages students to choose math as a major subject in high school -- not just in preparation for higher education but because having math up to maximum high school level is important in all walks of life. The article has already appeared in Aftenposten, a large Norwegian newspaper, and has been widely praised in Europe.
Issue 13 (April 4, 2006 - April 10, 2006) :
AN INTELLIGENT APPROACH TO PARSING TEXT
Goutam Saha demonstrates how a proposed parser identifies the part of speech (POS) of lexicons in the sentences of a particular language (in this case Bengali, or Bangla) as well as providing semantic information. A parser is used in machine translation (MT) for identifying the part of speech in a sentence -- and can be considered an intelligent parser if it handles semantics as well as POS identification. The aim of the rule-based intelligent Bangla parser described in this article is to ease the task of handling semantic issues in the subsequent stages in machine translation.

Issue 16 (April 25, 2006 - May 1, 2006) :
CORPORATE RENEWAL ENGINES
Kemal A. Delic writes: "Hypothetical corporate business is organized so that the mature products or services (first wave) are making the bulk of the corporate profit (double digit range) and grows modestly (single digit). Next wave is a growing business (strong double digit growth) while maintaining profitability (single digit). The future may critically depend on the third wave having no revenue objectives nor bringing profit while spawning critical, inventive technologies. Globalization following the spread of Internet is hinting at the several ways of organizing those three waves into orchestrated business whole."

UBIQUITY ALERT: The Waning Importance of Categorization
Espen Andersen of the Norwegian School of Management says: "The Internet is the fastest medium of them all, swarming with updates, links and searchability. Influence is determined by its readers, who, using dialogue and references, feed priorities to the search engines. Media companies who do not shape their product to this evolution will gradually lose their ability to decide what is important."

UBIQUITY ALERT: SMART SPACES
Ramesh Singh, Preeti Bhargava, and Samta Kain, define smart spaces as ordinary environments equipped with visual and audio sensing systems, pervasive devices, sensors, and networks that can perceive and react to people, sense ongoing human activities and respond to them. Their ubiquity is evident by the fact that various state of the art smart spaces have been incorporated in all situations of our life. These smart space elements require middleware, standards and interfacing technologies to manage complex interactions between them. Here, we present an overview of the technologies integrated to build Smart Spaces, review the various scenarios in which Smart Spaces have been incorporated by researchers, highlight the requirements of software infrastructure for programming and networking them, and mention the contemporary frameworks for interaction with them. Singh is Senior Technical Director, National Informatics Center,New Delhi, India. Bhargava and Kain are students.

UBIQUITY ALERT: AI REEMERGING AS RESEARCH IN COMPLEX SYSTEMS
Authors Kemal A. Delic and Umeshwar Dayal explain that the history and the future of Artificial Intelligence could be summarized into three distinctive phases: embryonic, embedded and embodied. They briefly describe early efforts in AI aiming to mimic intelligent behavior, evolving later into a set of the useful, embedded and practical technologies. Then they project the possible future of embodied intelligent systems, able to model and understand the environment and learn from interactions, while learning and evolving in constantly changing circumstances. They conclude with the (heretical) thought that in the future, AI should re-emerge as research in complex systems. One particular embodiment of a complex system is the Intelligent Enterprise.
Issue 39 (October 10, 2006 - October 16, 2006):
UBIQUITY ALERT: DISINVESMENT IN PUBLIC ENTERPRISES (PEs)
Dr. Vinay K. Srivastava, Department of Management, TMIMT, Moradabad, explains: "There has been phenomenal and tremendous growth of PE¹s in India. They were established to attain the Œcommanding heights¹ of the economy of the country and achieve rapid growth of industrialization and economic development. Some of these PEs later became Œwhite elephant¹ and started incurring losses. Several of them became chronically sick industries. The Govt. declared the disinvestment process, which began in 1991 with the sale of minority stakes in some PE¹s, shifted focus to strategic sales during 1999-2000 to 2003-04. The present UPA Govt. announced that , all disinvestment will be considered on a transparent and consultative case-by-case basis. The Govt. has approved the constitution of a ³National Investment Fund² comprising of proceeds from disinvestment. The present paper is an attempt to discuss same important issues such as restructuring, valuation of equity, Mechanism of disinvestment, Application of disinvestment proceeds, Parliamentary approval and political issues."
Issue 40 (October 17, 2006 - October 23, 2006):
UBIQUITY ALERT: Secure Delivery of Handwritten Signature
Computer scientists Samir Kumar Bandyopadhyay (University of Calcutta), Debnath Bhattacharyya (Heritage Institute of Technology) and Anindya Jvoti Pal (Heritage Institute of Technology) examine digital watermarking, the process that embeds data called a watermark into an object such that the watermark can be detected and extracted later to make an assertion about the object. Watermarking is either ²visible² or ²invisible². Although visible and invisible are visual terms watermarking is not limited to images, it can also be used to protect other types of multimedia objects. The research work of these authors is on watermarking techniques in particular, and they note that many of the proposed techniques share three specific weaknesses: complexity of copy detection, vulnerability to mark removal after revelation for ownership verification, and mark integrity issues due to partial mark removal. Their paper for Ubiquity presents a method for watermarking Handwritten Signature that achieves robustness by responding to these three weaknesses. They say the key techniques involve using secure functions to generate and embed image marks that is more detectable, verifiable, and secure than existing protection and detection techniques.
