Electronic Spectra of Chevreul's Salts
- Silva,Luciana A. da; Andrade,Jailson B. de; Toma,Henrique E.
The isomorphic series of double sulfites with empirical formula Cu2SO3.MSO3.2H 2O (where M is Cu, Fe, Mn, or Cd) have been prepared from the Cu(II) replacement by transition metal ions such as Mn(II), Fe(II) and Cd(II) ions in Chevreul's salt, Cu2SO3.CuSO3.2H 2O. As a consequence, the isomorphic species present distinct colors. Molecular modeling calculations were carried out for the dimeric [CuI2(SO3) 2(SO3)2]6- center. The electronic spectra of the Chevreul's salt consist of a charge-transfer band around 425 nm associated with the [CuI2(SO3) 2(SO3)2]6- chromophore and two ligand field transitions at 785 and 1000 nm involving the Jahn-Teller splitting of the...

- Chanson, Samuel T.; Wong, Chesney; Hung, Patrick C. K.
This handbook provides an overview of the major current electronic payment systems over the Internet and comments on the future of these systems. This is an important topic because electronic commerce is projected to grow to $1 trillion by year 2010. Rapid growth of the Internet and the World Wide Web are the major factors fueling the growth of electronic commerce. The Internet and the Web provide an infrastructure for business activities around the clock and around the globe. However, one of the main obstacles to this growth is the lack of secure electronic payment systems.
If electronic commerce over the...

Periódico electrónico: proceso de producción y estrategias discursivas
- Echevarría, Mirta
En relación con un conjunto textual dado, siempre existen dos lecturas posibles: la del proceso de producción (de generación) del discurso y la de la recepción de ese mismo discurso. Este trabajo encara el proceso de producción del periódico electrónico desde el punto de vista de las modalidades hipertextuales que dejan sus huellas en el texto. Estas huellas detectables ¿presentes en lo lingüístico, la imagen y el sonido- son algunas de las estrategias discursivas que, en el proceso de lectura, permiten construir el sentido de un texto.

Experimenting with Electronic Commerce on the PalmPilot
- Neil Daswani; Dan Boneh
. This paper describes our experience with implementing an electronic payment system for the PalmPilot. Although Palm OS lacks support for many desired security features, we are able to build a system suitable for small payments. We discuss the advantages and disadvantages of using a PDA to make secure payments as opposed to using a smartcard or a desktop PC. In addition, we describe the engineering of PDA-PayWord, our implementation of a commerce protocol that takes advantage of both elliptic curve and RSA public key cryptography to support payments efficiently on PDAs with limited processing capability. Keywords: electronic commerce, personal...

E-commerce Environments as 3D Electronic Institutions
- Anton Bogdanovych; Helmut Berger; Simeon Simoff
Many researchers have paid close attention in the recent past to 3D product presentation in E-Commerce systems. Surprisingly, not many practical results have been shown. In this paper we outline the reasons for the lack of success and propose the use of 3D Virtual Worlds that not only offer natural ways of product presentation but also provide means to satisfy the social needs of customers, which are mostly neglected in nowadays E-Commerce solutions. Virtual Worlds are somewhat unregulated environments, which do not have the means to enforce technological norms and rules on their inhabitants. But these norms can be enforced...

Emerging electronic infrastructures: exploring democratic components
- Åke Grönlund; Åke Grönlund
The concepts of electronic government and electronic democracy have common roots in that electronic government must rest on, and support, democratic principles. This article discusses how the components of a democratic society are treated as they are built into the emerging electronic infrastructures, dealing with services and dialogues pertinent to the functioning of the public sector, and tries to find emerging patterns. This article opens a discussion on the nature of the emerging infrastructures by reviewing four implementations of local e-democracy and putting them into the context of global e-government development, in particular the European Union’s development of “eEurope. ”...

Access management in electronic commerce system
- Wang, Hua
The definition of Electronic commerce is the use of electronic transmission mediums to engage in the exchange, including buying and selling, of products and services requiring transportation, either physically or digitally, from location to location. Electronic commerce systems, including mobile e-commerce, are widely used since 1990. The number of world-wide Internet users tripled between 1993 and 1995 to 60 million, and by 2000 there were 250 million users. More than one hundred countries have Internet access. Electronic commerce, especial mobile e-commerce systems, allows their users to access a large set of traditional (for example, voice communications) and contemporary (for example,...

Metabroker: AGeneric Broker for Electronic Commerce
- Steve Caughey David; David Ingham; Paul Watson
In traditional commerce, brokers act as middlemen between customers and providers, aggregating, repackaging and adding value to products, services or information. In the broadest sense of the term newspapers, travel agents and department stores can all be thought of as performing a brokering role. In today's Web, such services are lacking, with the result that individuals are forced to manually discover, collate and analyse information to meets their needs. In this paper, we highlight the requirement for brokering services for electronic commerce and describe the design of the Metabroker system, a generic framework for creating electronic brokers. The aim is...

Advanced security to enable trustworthy electronic voting
- Andreu Riera Jorba; José Antonio; Ortega Ruiz; Paul Brown
andreu.riera(a)scytl.com, jao(a)scytl.com, paul.brown(a)scytl.com Electronic voting (whether it is remote or poll-site) has a lack of transparency that makes its use controversial. Currently there is a lively debate regarding the deployment of electronic voting systems, with people arguing whether trustworthiness is only achievable by means of the use of backup paper trails. We believe that paper trails are not strictly necessary. In our opinion, the lack of transparency of electronic voting systems can be overcome to a great extent by using adequate security measures (technological, physical and procedural). Such security measures would provide clarity to the process and avoid the need...

A Multi-Agent Architecture for Electronic Payment
- Sheng-uei Guan; Feng Hua
The Internet has brought about innumerable changes to the way enterprises do business. An essential problem to be solved before the widespread commercial use of the Internet is to provide a trustworthy solution for electronic payment. We propose a multi-agent mediated electronic payment architecture in this paper. It is aimed at providing an agent-based approach to accommodate multiple e-payment schemes. Through a layered design of the payment structure and a well-defined uniform payment interface, the architecture shows good scalability. When a new e-payment scheme or implementation is available, it can be plugged into the framework easily. In addition, we construct...
