Consistent model for drain current mismatch in mosfets using the carrier number fluctuation theory

PostprintThis work presents an approach for accurate MOS transistor matching calculation. Our model, which is based on an accurate physics-based MOSFET model, allows the assessment of mismatch from process parameters and valid for any operating region. Experimental results taken on a test set of transistors implemented in a 1.2 /spl mu/m CMOS technology corroborate the theoretical development of this work

Business process modelling to improve incident management process

Business process management (BPM) is an approach focused on the continuous improvement of business processes, providing for this a collection of best practices. These best practices enable the redesign of business processes to meet the desired performance. IT service management (ITSM) defines the management of IT operations as a service. There are several ITSM frameworks available, consisting in best practices that propose standardizing these pro- cesses for the respective operations. By adopting these frameworks, organisations can align IT with their business objectives. Therefore, the objective of this research is to understand how BPM can be used to improve of ITSM processes. An exploratory case study in a multinational company based in Lisbon, Portugal, is conducted for the improvement of the time performance of an inci- dent management process. Data were gained through documentation, archival records, interviews and focus groups with a team involved in IT support service. So far, the as-is process was elicited, and respective incongruences clarified. During the next months the authors intend to identify the main problems and simulate the appropriate BPM heuristics to understand the impact in the busi- ness organisation.info:eu-repo/semantics/acceptedVersio

A Verification-Based Conflict Resolution Strategy for Knowledge Management Systems

Knowledge Management Systems may store knowledge in many diverse forms such as people, intellectual assets, documents, databases, directories, and expert systems. When knowledge is integrated from a wide variety of sources, it is inevitable that conflicts between knowledge will occur. Many knowledge sources inherently constrain the stored knowledge for criteria such as consistency or referential integrity, removing opportunities for inaccuracies and potentially increasing accuracy. This paper presents a conflict resolution strategy for knowledge stored in diverse sources that uses the rigor of the verification of each knowledge source as an indicator of its potential accuracy
