Reducing revenue loss due to disturbances in utilities using buffer tanks - A case study at Perstorp

Utilities, such as steam and cooling water, are often shared by several production areas at an industrial site. In order to minimize the loss of revenue due to disturbances in the supply of utilities, the optimal supply of utilities to different areas has to be determined. It is not evident how utility resources should be divided, as both buffer tank levels, the connections between areas, and the

How Neuroscience Changes, Complicates, and Complements Contemporary Film Studies

As a result of recent research discoveries and technological advancements within neuroscience, a growing interest in the brain and its functions permeates not only film studies, but also the field of humanities as a whole. Yet, the neuroscientific influence on contemporary film studies is not easily defined; on the contrary, film scholars with different starting points identify fundamentally diver

Strategies for Companies in Supply Chains with turbulent environments

The borderless world is providing new opportunities for conducting business, both within Europe and between continents. Sustainable competition will be harder to attain and competition will become fiercer, day-by-day. The Austrian school of strategy emphasizes change, continuous innovation, and entrepreneurial discovery as sources of supernormal profits. An important assumption is that these super

Numerical investigation of two-phase aqueous foam flow for heat exchanger applications

This work details investigation of two-phase aqueous foam flow, which is applicable for developing energy-efficient heat exchangers. In such heat exchangers, heat transfer rates are enhanced due to the structure and properties of aqueous foam, namely gas bubbles separated by a thin liquid film. Aqueous foam is noted to have an especially large inter-phase contact surface and reduced surface tensio

Issues and Challenges with Industrial-Strength Product Composition

One way to deal with product lines and products that have to exist in many variants is to use a component-based approach. This allows a lot of flexibility in creating new products and can reduce time and costs. However, the flexibility in composing products from a base of components is not without problems. Complexity increases in the composition process when combining many components to one large

Early Control Development in Sweden

This article gives a glimpse of the early development of Automatic Control in Sweden covering the period up to the mid 1960s. Much of the early developments took place in industry and the defence establishments. Process control, particularly in the pulp and paper industry, power systems, and military projects were strong drivers for the technology. The article ends with the emergence of control in

Flexible application development and high-performance motion control based on external sensing and reconfiguration of ABB industrial robot controllers

New robot applications increasingly require external sensing to accomplish robustness and performance despite the variations and uncertainties that come with the increasing demands on flexibility for manufacturing of customized products. The demands on productivity then require high performance, which for well known feedback-control reasons means short response times from external process event to

Syrian Water Resources between the Present and the Future

Water scarcity is one of the main challenges facing Middle Eastern countries. A typical country in this respect is Syria. This paper estimates projections for the available water resources, water balance, and available water per capita (AWPC) in Syria until 2050 in relation to possible future climate changes, national development agendas, water constraints, and water management alternatives. Resul

Hardening/Softening Plastic Analysis of an Adhesive Joint

Closed-form solutions for the plastic response of a symmetric double-lap joint are presented. The adherents are assumed to behave linear elastically in pure tension, whereas the adhesive is assumed to be in a state of pure shear. The shear stress-strain behavior of the adhesive is approximated by a bilinear curve, and both hardening plasticity approximating ductile adhesive behavior, and softening

Det fackliga medlemsraset i Sverige oktober 2006 - oktober 2007: en första översikt

Den fackliga organisationsgradens utveckling i Sverige mellan oktober 2006 och oktober 2007 redovisas. Under denna 12-månadersperiod föll andelen fackligt anslutna löntagare med drygt fyra procentenheter. Om man avrundar till heltal rör det sig om ett medlemsras på hela fem procentenheter, från 77 till 72 procent fackanslutna. Det är den största fackliga nedgången under loppet av ett enda år i Sve

Cybernorms and Virtual Solidarity

The sharing of computer programs, movies and music over the Internet marks an all time high in the persistent controversy between intellectual property owners and reproduction technologies as file sharing has gradually become a natural element in the everyday life of today’s younger generations. At present, the magnitude of the expanding gulf between traditional society’s intellectual property rig
