In this paper we explore the feasibility of implementing Residue Number System (RNS) based DSP algorithms on Lookup table based Field Programmable Gate Arrays (FPGAs). In this process, Binary Decision Diagrams are used for logic representation, and a new minimizing algorithm for incompletely specified functions is introduced. A sample residue arithmetic based design is presented along with prom...

With the growth of adaptive educational systems available to students, integration of these systems is evolving from an interesting research problem into an important practical task. One of the challenges that needs to be addressed is the development of mechanisms for student model integration. The architectural principles and representation technologies employed by adaptive educational systems...

Introduction Reverse engineering aims at obtaining high level representations of programs. Reverse engineers typically start with a low level representation of a system (such as binaries, plain source code, or execution traces), and try to distill more abstract representations from these (such as, for the examples just given, source code, architectural views, or use cases, respectively). Revers...

A key objective for ubiquitous environments is to enable system interoperability between system’s components that are highly heterogeneous. In particular, the challenge is to embed in the system architecture the necessary support to cope with behavioral diversity in order to allow components to coordinate and communicate. The continuously evolving environment further asks for an automated and o...

Context: Many software architectural decisions are group decisions rather than decisions made by individuals. Consensus in a group of decision makers increases the acceptance of a decision among decision makers and their confidence in that decision. Furthermore, going through the process of reaching consensus means that decision makers understand better the decision (including the decision topi...

The translation of English text into American Sign Language (ASL) animation tests the limits of traditional MT architectural designs. A new semantic representation is proposed that uses virtual reality 3D scene modeling software to produce spatially complex ASL phenomena called “classifier predicates.” The model acts as an interlingua within a new multi-pathway MT architecture design that also ...

With the growth of adaptive educational systems available to students, integration of these systems is changing from an interesting research problem into an important practical task. One of the challenges that need to be accepted on the way is the development of mechanisms for student model integration. The architectural principles and representation technologies employed by the adaptive educat...

The focus of past machine learning research for Reading Comprehension tasks has been primarily on the design of novel deep learning architectures. Here we show that seemingly minor choices made on (1) the use of pre-trained word embeddings, and (2) the representation of outof-vocabulary tokens at test time, can turn out to have a larger impact than architectural choices on the final performance...

The Viable System Architecture is applied to the problem of analyzing and extending an existing software system. This software architecture approach is based on Stafford Beer’s Viable System Model. The Groove collaboration system is chosen to illustrate how this software architectural methodology can be used to extend an existing system with adaptive features. The Groove system architecture is ...

Distributed systems' runtime behavior can be difficult to understand. Concurrent, distributed activity make notions of global state difficult to grasp. We focus on the runtime structure of a system, its execution architecture, and propose representing its evolution as a partially ordered set of predefined architectural event types. This representation allows a system's topology to be visualized...
