A major disadvantage of feedforward neural networks is still the difficulty to gain insight into their internal functionality. This is much less the case for, e.g., nets that are trained unsupervised, such as Kohonen’s self-organizing feature maps (SOMs). These offer a direct view into the stored knowledge, as their internal knowledge is stored in the same format as the input data that was used fo

Syftet med detta utkast är att analysera hur personal inom socialtjänsten tolkar, definierar och upplever ett behandlingsprojekt, som involverade olika myndigheter, benämnt Motverka Våld och Gäng. De anställda inom socialtjänsten upplever att projektet kommit ”uppifrån”, från staten, och som en konsekvens av att socialtjänsten utpekats som inkompetent att hantera ungdomsvården. Satsningen framst

Varje program och kurs på Lunds universitet skall få en genuscertifieringsstämpel. Universitetets lärare skall tvingas vara genusmedvetna och bland de studerande skall det finnas en genusombudsman. Professor Tiina Rosenberg vid Centrum för genusvetenskap har initierat en ny form av kontroll och härskarteknik, forkortat utgave i Sydsvenskan 19.okt08.

A new stream cipher, Grain-128, is proposed. The design is very small in hardware and it targets environments with very limited resources in gate count, power consumption, and chip area. Grain-128 supports key size of 128 bits and IV size of 96 bits. The design is very simple and based on two shift registers, one linear and one nonlinear, and an output function

An improved design for acoustic particle separation in multichannel chips is presented. By wavelength matching of the microfluidic channel widths and the width of the interlacing bulk silicon, a well tuned resonating multilayer system can be accomplished. The acoustically tuned microchip offers considerable improvements in regards to particle focusing performance, i.e. separation efficiency, at fi

In an attempt to shed light on the role of the polyamines, putrescine, spermidine, and spermine in cell cycle progression, polyamine biosynthesis has been analyzed during the cell cycle of Chinese hamster ovary cells, and cell cycle kinetics have been investigated in cells treated with polyamine biosynthesis inhibitors. Cells were synchronized with the mitotic detachment technique, and at various

Extended producer responsibility (EPR) is a concept from Industrial Ecology that has changed waste management policies inside and gradually outside the member countries of the Organisation for Economic Co-operation and Development (OECD). This article bridges the gap in our understanding of the policy process wherein policy change occurred. It employs the Advocacy Coalition Framework (ACF) to expl

The author of the Gospel of Matthew uses the form and technique of ancient biography to present Jesus as a true leader of the people of Israel. A biographical-narrative reading of the first chapters of Matthew clarifies the powerful rhetoric by which the author shows the reader the untrue present leadership of Jerusalem and introduces the ideal king, Jesus Messiah. In this way the author has begun
