We determine the computational complexity of the problem of ordering a set of n numbers into a sequence as well as the problem of ordering them into a cycle, such that the maximum sum of k successive numbers is minimal. The former problem arises in effectively storing multimedia data on multi-zone hard disks. Conclusions: Both the problems are easy for k = 2 and strongly NP-hard for any k ≥ 3. ...

Philips recently released a new VCSEL and photodiode product family for the fast growing FDR InfiniBandTM generation. In this work we review the influence of production process variations on VCSEL characteristics, the FDR VCSEL transmission behavior as well as wear-out reliability characteristics. Data collected during an initial 15 wafers pilot production batch verify that FDR VCSEL manufactur...

A high-level architecture of a hybrid reconfigurable CPU, based on a Philips-supported core processor, is introduced. It features the Philips XPLA2 CPLD as a reconfigurable functional unit. A compilation chain is presented, in which automatic implementation of time-critical program segments in custom hardware is performed. The entire process is transparent from the programmer's point of view. T...

We consider optical disks consisting of several stacked layers, one of which is a recording layer which consists of a dye (for write once disks) or a phase-change material (for rewritable disks). Due to the illumination by a laser spot the temperature increases locally in the disk. The pulsing laser spot writes marks in the recording layer that represent the digitally encoded data. To guide the...

In this paper we describe some characteristics of the acoustic modeling used in the Philips continuous-speech recognition system for the DARPA Hub-4 1997 evaluation, which are related to robustness issues. We aimed at a conceptually simple system: We trained two model sets on 70 hours of the Hub-4 training data, one for within-word and one for crossword decoding. These model sets were used for ...

By o ̧ering enterprise telehealth, home monitoring, personal emergency response systems, and personal health services that address multiple groups within a population, from intensive ambulatory care for high-risk patients, to prevention and personal health programs for the general population. Through ...

In Philips there is a need for many competent software developers. Not for everyone in the company software development is a real engineering activity. They claim that there are no fundamental theories underlying software and software construction. On the other hand, only a few universities offer a curriculum in software engineering, most curricula deal with computer science. Since ten years we...
