A series of design principles relevant to creating graphics for games interfaces were interpreted from the work of leading interaction experts. Students studying for an MSc in computer Games graphics were asked to explore how the principles might improve enjoyment of a game. the graduates of the course consider visual themes and their layout;they were asked to develop graphical designs to test ideas and evaluate them within the group. the purpose of the activity was to consider how emotional responses might be improved, during game play, beyond levels of satisfaction usually asociated with usability.

the CMISS software package is used in many biological research areas for multiscale computational biology and visualization. Some major components of this suite have recently been released under an open source license, specifically modules for field storage, 3D graphics, mathematical field operators and image processing. Interfaces are being developed to facilitate integration with other applications and the internet.

Since 1996, we have been researching a photocathode single-cell pillbox rf gun for future light sources, and to date have achieved a maximum field gradient of 187 MV/m with a chemical etching processed cavity. For the last three years, we have been focusing on the development of a stable and highly qualified UV laser source for the rf gun. the UV laser pulse (10 Hz) energy is 80 μJ/pulse at the entrance window. the energy stability (rms) of the laser has been reduced to 0.2∼0.3% at the fundamental and 0.7∼1.3% at the third harmonic generations. this stability can be held continuously for two months, 24 hours a day. the improvement is the result of the stabilization of the laser system in a humidity-controlled cleanroom. In addition, the ideal spatial and temporal profiles of a shot-by-shot single laser pulse are essential to suppress the emittance growth of the electron beam from the rf gun. We prepared a deformable mirror for spatial shaping and a spatial light modulator based on fused silica plates for temporal shaping. With a computer-aided deformable mirror, we obtained a minimum horizontal normalized emittance of 1.74 mm mrad with a beam energy of 28.8 MeV, holding its net charge to 0.09 nC/bunch. We applied the variable quadrupole method to evaluate the emittance. the 3D shape of the laser was spatially flattop with a 1 mm diameter on the cathode and temporally a function of sech(t) with a pulse duration of 5 ps (FWHM). this laser pulse was illuminated on the copper cathode with normal incidence. We are currently preparing both adaptive optics to automatically optimize the electron beam parameters for lower emittance with a feedback routine.

Summary form only given. At first glance it can look like open source software development violates many, if not all, of the precepts of decades of careful research and teaching in software engineering. One could take a classic SE textbook and compare the activities elaborated and advocated in the various chapters with what is actually done in plain sight in the public logs of an OSS project in say SourceForge. For a professor of software engineering this might make for rather depressing reading. Are the principles of SE being rendered obsolete? Has OSS really discovered Brooks' silver bullet? Or is it just a flash in the pan or fool's gold? In this paper, the author mainly looks at one aspect of open source development, the 'problem' of creating usable interfaces, particularly for non-technical end-users. Any approach involves the challenge of how to coordinate distributed collaborative interface analysis and design, given that in conventional software development this is usually done in small teams and almost always face to face. Indeed all the methods in any HCI text just assume same-time same-place work and don't map to distributed work, let alone the looser mechanisms of OSS development. Instead what is needed is a form of participatory usability involving the coordination of end users and developers in a constantly evolving redesign process.

A semiconductor device simulator PC1D is used to investigate the behavior of photosensitive polycrystalline p/i and p/i/n structures. the main physical characteristics - impurity concentrations, diffusion lengths, bulk and surface recombinations are varied in a wide range. the junction depths and thicknesses of the constituent layers are fixed. the obtained electrical characteristics for both photosensitive structures are compared. On the base on. the obtained results, optimized structures of photosensitive sensors are proposed. It is shown that the PC1D can be successfully applied for simulation of polycrystalline photosensitive structures.

In this article the inter-symbolic interference is analyzed as a disturbance. At given information flow and known pulse characteristics of the channel the received signal could be defined with precision up to additive disturbance. A mathematical model of a radio channel with frequency-dependent parameters received under inter-symbolic interference is proposed. this method for compensation of inter-symbolic interference allows evaluation of errors probability during the process of the received signal recognition for different types of the signal modulation and proposes algorithms for inter-symbolic interference compensation.

the cone-beam computer tomography (CT) is relatively new non-destructive testing method, used in the industry. Withthe aid of this method, the attenuation coefficient of x-ray is tested. the fact that the samples are characterized by a different density and thickness explains why the various contrasts are obtained in the end results. A digital detector detects this information, in form of grayness' ratio. In contrast to the known principle of CT in medical application, the cone-beam CT uses a volumetric beam to scan the test object and therefore obtains a series of 2D images. As a result of these scans the reconstruction is a 3-dimensional model of the tested object. During the reconstruction process, by which the artefacts are often created, an x-ray tube emits polychromatic spectrum and is called beam hardening. this process takes place because the low energetic spectrum part in the material is better absorbed than in the higher energetic one. the basic application of this method is the visualization of the inner and outer structures of electronic components, packaging and interconnection technologies. this paper will describe the basics of computer tomography, the typical beam hardening artefacts and the method to reduce their influence on the imaging quality of the measured objects. Additionally, the examples of this non-destructive testing method will also be presented.
