We developed the MODE framework to aid us in the design and evaluation of three multimodal mobile applications. The reason we developed our own framework was two-fold. Firstly, users have encountered problems when trying to use existing applications on their mobile phones complaining that they find them difficult to access and use. Secondly, we were building quite complex mobile applications and we were building into these applications multimodality. We realized, therefore, that it was vital that we think of ways in which we could involve users throughout the design process in order to build more user centered applications. The second phase of the MODE framework for the design and evaluation of multimodal mobile applications is presented in this paper

This article introduces a novel method for reducing dimensional complexity of classification problems which are frequently present in gene microarray analysis. Revealing the most relevant subset of genes among few thousands of analyzed genes is necessary to get accurate disease classification. Attribute (gene) filter was developed for such a purpose. The filter, first introduced as mutual information feature selection (MIPS) was coupled with the support vector machines (SVM) classifier in the leave-one-out (LOO) loop, which resulted in an efficient and reliable tool named MIFS/SVM hybrid. The set of gene microarrays, which consists of two leukemia types, was used as a benchmark. That particular set was thoroughly analyzed by others. Hence, it was appropriate to use it for testing the accuracy of MIFS/SVM hybrid based filter

The main problem of visual query languages for geographical data concerns ambiguity of the query. In fact a query can have different visual representation and a visual representation of a query can have different interpretations. Increasing the number of the objects of the query increases the ambiguity. This ambiguity derives from the fact that a query can lead to multiple interpretations both for the system, and for the user. He, by his actions may not represent his intentions so that the system can be brought to a wrong interpretation. So, he cannot express his exact query and different queries can be formulated to obtain the user goals. The present work proposes an approach that allows the user to represent only desired constraints and to avoid the representation of undesired constraints in the visual representation of the query

Emerging technologies, such as affective computing, have potential to enhance human-computer interaction (HCI). They are still at a prototype stage and effective working systems are still some years off. The problem is that much development is driven by what is technically possible at this time, rather than by what users require. By using Wizard-of-Oz (WOZ) methods to simulate a working affective system, it is possible to examine some user behaviours and preferences with such a system

There is a great need of data exchange between XML and RDB (relational database) in many Web services and applications, which is implemented by XSLT currently, using a flat XML document as an intermediary and describing the transformation by XSLT. This process is indirect and low-performance, especially dealing with complex structure or massive data. In this paper, we propose a new approach with a set of mapping rules and a direct process to make the exchange simpler and more effective

This paper presents a cost-reductive communication schema for distributed multiagent environments containing mobile agents. Communication cost reduction is achieved by employing autonomous mobile mailbox as a message-relay system component. Beneficial modes of mobile mailbox behavior are identified under various operational conditions. A mobile mailbox model is proposed and simulation conducted in order to verify its usability

Managing an organization requires access to information in order to monitor activities and assess performance. Trying to understand what information an organization has can be challenging because the information systems collect and process vast amount of data in various forms. To flow in the running stream of rapidly changing, increasingly competitive global market scenario and increasingly volatile consumer and market behavior and rapidly shortening product life cycles, business enterprises today are necessary to analyze accurate and timely information about financial operations, customers, and products using familiar business terms, in order to gain analytical insight into business problems and opportunities. Enterprises are building business intelligence systems that support business analysis and decision making to help them better understand their operations and compete in the marketplace. This paper describes the life cycle comprising various phases in the development of a BI system. The paper elaborates the implementation issues of BI in an organization focusing a case study

This paper set out to use a camera attached to a mobile terminal in order to inquire a car and track its location anywhere. The technology based in the research is to automatically recognize and verify license plates on the front and back of a car. The plates are input through a camera attached to a mobile terminal. The technology enables us to detect a car registration number and to transmit it along with the location of the terminal to a server through a wireless communication network. The information of a car obtained through the terminal is encoded and transmitted to a server in a remote place through a wireless communication network. The car registration number and its location information are decoded and transmitted as a text to the server in a remote place. In order to track a user's location through spatial relative distance estimated in real-time, the server uses the spatial and attribute information which are the most prior to the desired data value. With this property information, the right location can be calculated
