Popular Abstract in Swedish I ett atomkraftsmikroskop avbildar man ytor och föremål genom att känna av ojämnheter med hjälp av en vass spets. Spetsen har en diameter på ca en tusendel av ett hårstrå. I avhandlingen beskrivs en teknik för hur man med denna extremt vassa spets kan manipulera nanometerstora metall- och halvledar partiklar mellan elektroder på en yta för att bygga elektriska komponentIn this thesis a technique to manipulate nanoparticles with an atomic force microscope (AFM) is presented. Particles in the size range of 5-500 nm could be positioned in arbitrary two-dimensional patterns on different surfaces by mechanically pushing them with the AFM tip. The technique which is material-independent can be applied to any type of nanometer-sized particles or objects that are free t

A wavelet generator producing 100 ps short pulses at 60 GHz is presented. The wavelet generator consists of a gated tunnel diode (GTD) integrated in parallel with an inductor. This forms a negative differential conductance (NDC) oscillator with the ability to switch the NDC property on and off, which makes it possible to generate short pulses. In the experiments described, the wavelet generator dr

This article deals with the use of the term "modernism" in influential film studies texts primarily in the 1970s and 1980s. The main focus is put on the debate between film theoreticians Peter Wollen and Paul Willemen.

The Coastal Inlets Research Program (CIRP) is developing predictive numerical models for simulating the waves, currents, sediment transport, and morphology change at and around coastal inlets. Water motion at a coastal inlet is a combination of quasi-steady currents such as river flow, tidal current, wind-generated current, and seiching, and of oscillatory flows generated by surface waves. Waves c

We discuss the use of the Mechatronics Control Kit from Mechatronic Systems, Inc. for control education and research. The Mechatronics Control Kit can be configured with several distinct plants, including a simple DC motor, an inertia wheel pendulum and a Pendubot. The digital electronics are fully integrated and include a Texas Instruments DSP development system, the TMS320C6711 DSK Board (a DSP

The chapter describe the early implementation of safety alarms in Sweden and the result of a study at a service centre i Linkoping.

Abstract in UndeterminedFor centuries rammed earth has been a method of construction in various parts of the world. It is an economical building technique as earth is an abundant cheap resource. It is durable, safe and a desirable building technique for hot climates. This paper is discussing a workshop activity in building with sustainable rammed earth construction methods in Egypt. It adds to pre

In this paper we show how to calibrate a camera, mounted on a robot, with respect to the intrinsic camera parameters when the so-called hand-eye transformation between the robot hand and the camera is unknown. The calibration is based directly on the spatial and temporal derivatives in an image sequence and do not need any matching and tracking of features or a reference object. The calibration is

In the search for new pharmaceutically active compounds, it is recognized that Nature produces structurally different compounds in a great variety. By having the compounds or extracts tested in defined systems, new drugs or more often leads (a compound that has an interesting but moderate activity) can be found. When a lead is found, structurally similar compounds with modified functional groups a
