The capabilities of multimodal applications running on the web are well delineated since they are mainly constrained by what their underlying standard mark up language offers, as opposed to hand-made multimodal applications. As the experience in developing such multimodal web applications is growing, the need arises to identify and define major design options of such application to pave the way...

Mobile software industry is suffering from the illegal usage of the software. PKI will not be a solution for small software distribution. We introduce a lightweight but safe method to prevent illegal usage of mobile phone software, by instrumentation on binary for device-identity check. The method is now being implemented on a presumable code on demand (COD) server for WIPI (Wireless Internet P...

in recent years, routing has been the most focused area in ad hoc networks research. on-demand routing in particular, is widely developed in bandwidth constrained mobile wireless ad hoc networks because of its effectiveness and efficiency. most proposed on-demand routing protocols are built and relied on single route for each data session. whenever there is a link disconnection on the active ro...

Run-time packing is a technique employed by malware authors in order to conceal (e.g., encrypt) malicious code and recover it at run-time. In particular, some run-time packers only decrypt individual regions of code on demand, re-encrypting them again when they are not running. This technique is known as shifting decode frames and it can greatly complicate malware analysis. The first solution t...

The nearly omnipresence of the Internet and the steady increase of wireless computing and mobile devices require highly dynamic adaptable distributed system architectures. Building such architectures needs a combination of key concepts from component technology and distributed systems. Mobile agents provide this combination. We use mobile agents as the building blocks of a component-based syste...

Domain-specific generators will increasingly rely on graphical languages for declarative specifications of target applications. Such languages will provide front-ends to generators and related tools to produce customized code on demand. Critical to the success of this approach will be domain-specific design wizards, tools that guide users in their selection of components for constructing partic...

Characterization and evaluation of a biological submerged filter was carried out on a full-scale pilot plant performing removal of biochemical oxygen demand (BOD) and total nitrogen (TN) from pre-treated urban wastewater. The average influent values of BOD5, chemical oxygen demand (COD) and TN were 370, 1,015 and 60 mg/L, respectively. The pilot plant produced good discharge quality during stea...

Domain-specific generators will increasingly rely on graphical specification languages — applets — for declarative specifications of target applications. Applets will provide front-ends to generators and related tools to produce customized code on demand. Critical to the success of this approach will be domain-specific design wizards, tools that guide users in their selection of components for ...

Most commercial software packages present the user with a monolithic software program bundling many functions and features. The user pays for the unneeded features, and mobile devices have insufficient resources to cope. We introduce Sparkle, a proof-of-concept, mobile middleware for code adaptation using the code-on-demand design paradigm. To allow as many useful applications as possible to ru...
