We consider statechart models of discrete control embedded programs operating under severe memory constraints. There have been very few results in code generation for such systems. We analyze code generation methods for embededded processors utilizing C as an intermediate language and runtime interpreters. We choose a suitable subset of hierarchical statecharts and engineer an efficient interpr...

We present a deterministic summary structure over update streams that enables deterministic and the first space-optimal algorithms for a variety of problems, including, estimating frequencies, finding approximate frequent items, finding approximate quantiles, finding hierarchical heavy hitters, approximately optimal B-bucket histograms, estimating inner product sizes, etc..

This is a simple introduction to fast multipole methods for the N-body summation problems. Low rank approximation plus hierarchical decomposition leads to fast O(N) or O(N logN) algorithms for the summation problem or equivalently the computation of a matrix-vector product. Code for 1-D problem is presented for a better illustration. We consider a summation problem in the form:

This paper formulates a model in which a …rm simultaneously chooses its organizational structure and product position. The …rm’s production is knowledge-intensive, requiring employees to solve problems. A vertical hierarchy in which workers refer unsolved problems to managers facilitates the acquisition and leveraging of managers’superior knowledge. I show that a larger span of control is compl...

Customers of large enterprises post threads in companysupported online forums to discuss solutions to product malfunctions, errors and problems. The ability to retrieve the most relevant threads in response to a customer’s search query in the product forums requires robust search capabilities. Unfortunately, the lack of (recommendation) links between the threads in the product discussion forums...

The paper explores the application of Web 2.0 technologies to support product development efforts in a global, virtual and cross-functional setting. It analyses the dichotomy between the prevailing hierarchical structure of CAD/PLM/PDM systems and the principles of the Social Web under the light of the emerging product development trends. Further it introduces the concept of Engineering 2.0, in...

In this paper we present key elements of a peer to peer (P2P) based software architecture for integrated and collaborative product engineering. We argue that distributed and cross-enterprise product lifecycle management can benefit from the availability of decentrally managed product model repositories.We present the overall system architecture of a platform called Peer-to-Peer Product Collabor...
