- 2000

Tidskriftsartikel (refereegranskat)abstract
- Hybrid inorganic-organic polymers (ORMOCER (R)s) have been developed and tested for evaluation in optical and electrical interconnection technology. The photopatternable materials with negative resist behaviour are composed of inorganic oxidic structures cross-linked or substituted by organic groups. They are prepared from organosilane precursors by sol-gel-processing in combination with organic crosslinking of polymerizable organic Functions, As a result of these functionalities the properties of the ORMOCER (R)s can be adjusted to particular applications. Systematic variation of composition combined with adaptation to micro system technology allows great flexibility in processing. The main features of these materials are: Combined use as dielectric and passivation layers in electrical systems and devices as well as core and cladding for optical applications enables e/o applications with high integration levels, Postbaking at moderate temperatures (120 degreesC - 170 degreesC) enables processing on low-cost substrates such as FR-4 and BT. Easily adaptable to thin film technology: spin-on with planarisation >90% and via diameters down to 20 mum have been achieved.

Morphological Template Decomposition for DT-CNN
- 2002
-
Ingår i: Proceedings BNAIC?02. ; , s. 35-42
-
Konferensbidrag (refereegranskat)abstract
- In this paper the established link between Mathematical Morphology and DT-CNN is used to derive a new template decomposition procedure. It is based on the decomposition of morphological structuring elements. From a practical point of view, template decomposition is an important issue since image processing operations can be non-local while the cells in physical DT-CNN realizations often only communicate with cells in their direct neighborhood. Here we apply techniques from morphological algebra to derive a DT-CNN template decomposition strategy, which is far more efficient in terms of the number of templates in the decomposition than the traditional decomposition strategy. In a typical 9 x 9 example, the number of templates reduces from 125 to 14.

Constructing a neural system for surface inspection
- 2004

- Visual quality assurance techniques focus on the detection and qualification of abnormal structures in the image of an object. The features of abnormality are extracted through image mining, whereupon classification is performed on characteristic combinations. Many techniques for feature extraction have been proposed, but the feed-forward neural network is seldom utilized despite its popularity in other application areas. Based on this wide experience base, this paper shows how a multi-tier feed-forward network can be constructed to model detectable peaks using only the physical properties of the image domain. This generic architecture can easily be adapted for different applications, as in metal plate inspection and protein detection, with mean error rate below 5%

A novel and rapid PCR-based method for genotyping human papillomaviruses in clinical samples.

Tidskriftsartikel (refereegranskat)abstract
- Many human papillomavirus (HPV) genotypes are associated with cervical carcinoma. We demonstrate the utility of an innovative technique for genotyping of HPV in cervical tissue samples. This method provides an accurate means of identification of the specific HPV genotypes present in clinical specimens. By using the MY09-MY11 and the GP5(+)-GP6(+) consensus primer pairs, HPV sequences were amplified by nested PCR from DNA isolated from cervical smear samples. This led to the production of an approximately 140-bp PCR product from the L1 (major capsid) gene of any of the HPVs present in the sample. PCR was performed with a deoxynucleoside triphosphate mixture which resulted in the incorporation of deoxyuridine into the amplified DNA product at positions where deoxythymidine would normally be incorporated at a frequency of about once or twice per strand. Following the PCR, the product was treated with an enzyme mix that contains uracil N-glycosylase (UNG) and endonuclease IV. UNG removes the uracil base from the nucleotide, and endonuclease IV cleaves the phosphodiester bond at this newly formed abasic site, producing fragments of various sizes. By having end labeled one of the amplification primers, a DNA ladder which is analogous to a "T-sequencing ladder" was produced upon electrophoresis of the products. By comparing this T-sequencing ladder to the known sequences of HPVs, the genotypes of unknown HPV isolates in samples were assigned. Data showing the utility of this technique for the rapid analysis of clinical samples are presented.

- Extreme helium stars (EHes) with effective temperatures from 8000 to 13 000 K are among the coolest EHes and overlap the hotter R CrB stars in effective temperature. The cool EHes may represent an evolutionary link between the hot EHes and the R CrB stars

Modular and hierarchical specialization in neural networks
- 2003
-
Ingår i: Istanbul University - Journal of Electrical & Electronics Engineering. ; 3:1, s. 719-726

Tidskriftsartikel (refereegranskat)abstract
- Modularity and hierarchy are fundamental notions in structured system design. By subdividing a large and unstructured problem into smaller and tractable chunks, design automation becomes possible. In this paper we discuss the use of modularity and hierarchy for functional specialization during the development of neural networks. We study the behavioral differences and requirements for back-propagation training of feed-forward networks. Further we illustrate that a deliberate mix of hierarchically imposed evaluation functions will improve network accuracy and learning speed.

Konferensbidrag (refereegranskat)abstract
- From a practical point of view, template decomposition is an important issue since image processing operations can be non−local while the cells in physical CNN realizations often only communicate with cells in their direct neighborhood. In this paper the existing relation between Mathematical Morphology and CNNs is used to derive an optimal template decomposition strategy for a specific class of templates. The strategy is based on the decomposition of morphological structuring elements.

Model-based containment of process fault dissemination

-
Tidskriftsartikel (refereegranskat)abstract
- The past decade has witnessed a marked increase in distributed system complexity. This was driven by a maturing technology that steadily decreased the number of faults. Unfortunately these fewer faults have become exponentially more costly. It becomes mandatory to detect faults prior to taking effect on the network. Such an early detection requires a new test, detection and fault containment strategy, of which the outline and some basic ingredients are sketched here.
