I define the concepts of multifuncoid (and completary multifuncoid) and upgrading. Then I conjecture that upgrading of certain multifuncoids are multifuncoids (and that upgrading certain completary multifuncoids are completary multifuncoids). I have proved the conjectures for n 6 2. This short article is the first my public writing where I introduce the concept of multidimensional funcoid which...

Design systems can have considerable embedded value. Improvements in such systems are better achieved through upgrades than through complete replacements. To determine how best to make these upgrades requires a systems view of design, ^uch a view is provided by what we call TAO (testaspect-operator) graphs. Nodes in these graphs represent aspects of the artifacts being designed while arcs repre...

The distributed development and maintenance paradigm for component delivery is fraught with problems. One wants a relationship between developers and clients that is autonomous and anonymous. Yet components written in languages such as C++ require the recompilation of all dependent subsystems when a new version of a component is released. The design of Java’s binary format has side-stepped this...

I define the concepts of multifuncoid (and completary multifuncoid) and upgrading. Then I conjecture that upgrading of certain multifuncoids are multifuncoids (and that upgrading certain completary multifuncoids are completary multifuncoids). I have proved the conjectures for n 6 2. The main conjecture from this article is now proved in the article “Multidimensional Funcoids“ This short article...

Chemical pulp mills such as Kraft, soda, or sulfite mills are current examples of biorefineries that can convert lignocellulosic biomass into energy, pulp or cellulose derivatives, and tall oil. While existing viscose pulps use a hemicellulose extraction to generate soluble sugars for ethanol production, in general there still exists a large potential for other more profitable applications of t...

The goal of the guarded software upgrading (GSU) framework is to minimize mission performance loss due to onboard software upgrading activities and that due to system failure caused by residual faults in an upgraded version. We exploit inherent system resource redundancies as the means of fault tolerance to meet the development cost and onboard resource constraints. Furthermore, we devise a mes...

Strange behavior may occur in networks due to the non-cooperative nature of decision making, when the latter are taken by individual agents. In particular, the well known Braess paradox illustrates that when upgrading a network by adding a link, the resulting equilibrium may exhibit larger delays for all users. We present here some guidelines to avoid the Braess paradox when upgrading a network...

This article traces work-life evolution in Sweden during recent decades against the backdrop of long-run structural change tied to class and gender. We examine the development of four key labor market features: (a) occupational sex segregation, (b) gender gaps in job quality, (c) skill upgrading and mismatch, and (d) youth employment. While occupational and educational upgrading is beneficial f...
