Strategier i tiden : En studie av telekomföretaget Ericssons nedläggningar i Norrköping och Linköping
- 2006
-
Bok (populärvet., debatt m.m.)abstract
- Hur gör ett företag som gör mer än det tidigare gjort för sin personal vid en nedläggning? Varför gör det överhuvudtaget mer än det tidigare gjort, eller ens behöver? I denna bok analyseras telekomföretaget Ericssons nedläggningar i Norrköping och Linköping under åren mellan 1999 och 2002. Författaren visar hur nedläggningarna utvecklades i samspel med sociala institutioner och i interaktion med fackliga organisationer såväl som bemanningsföretag, Trygghetsrådet och kommunala och statliga myndigheter. Här förfäktas idén att företagets agerande hängde samman med att etablerade organisationer genom sin tröghet till förändring hade skapat utrymme för nya organisatoriska lösningar i samband med rationaliseringar: bemanningsföretagen kunde nu ta över personalansvaret.Författaren gör också en genomgång av tidigare forskning om nedläggningar och personalinskränkningar, varvid modeller redovisas som förknippats med företag som ansetts ha tagit socialt ansvar när de lagt ner eller minskat på sin personal.

- This study examined a wide range of literature in order to describe factors associated with the concept of infant health. The design of the study is a literature review examining 21 research studies, written in the English language. The study explored which factors were found to exert an influence on the concept of infant health. The result showed that the concept infant health is dependent on many factors but what seems to exert an influence are foremost maternal health and well-being, the family's health care utilization and the parental assessment of their own health. Additional studies are needed to fully understand the concept of infant health. The need for an infant definition that empowers infant health arises because, if a common ground is not clearly established, miscommunication may arise. Furthermore, there is a need to initiate a model for infant health.

Sensor Interoperability and Fusion in Fingerprint Verification : A Case Study Using Minutiae- and Ridge-based Matchers
- 2006
-
Ingår i: 2006 9th International Conference on Control, Automation, Robotics and Vision, Vols 1- 5. - Piscataway, N.J. : IEEE Press. - 9781424403424 ; , s. 422-427

- Information fusion in fingerprint recognition has been studied in several papers. However, only a few papers have been focused on sensor interoperability and sensor fusion. In this paper, these two topics are studied using a multisensor database acquired with three different fingerprint sensors. Authentication experiments using minutiae and ridge-based matchers are reported. Results show that the performance drops dramatically when matching images from different sensors. We have also observed that fusing scores from different sensors results in better performance than fusing different instances from the same sensor. © 2006 IEEE.

Combined SEM and Stylus Profiling Sensoring for Improved Cylinder Liner Honing

Konferensbidrag (refereegranskat)abstract
- The demands on decreased environmental impact from vehicles are resulting in a strong push for decreased engine oil and fuel consumption.Recent engine tests have shown a promising reduction in oil consumption when using cylinder liners with a smoother finish than the current plateau honing.One approach to produce smoother liner surfaces is to replace SiC ceramic honing stones with diamond tools. However, even though the diamond honing process results in higher productivity, improved quality control is needed to monitor the degree of cold worked material - “blechmantel” (German), and the resulting risk of increased wear and scuffing.A number of petrol and diesel engine cylinder liners have been mapped to be able to verify the quality and consequences, in terms of wear and function, of the honing process. A new mapping method, combining SEM images and quantitative image analysis with traditional 2D profilometry has been developed and tested in this study. The surface mapping method developed was employed before and after the test to study effect of running-in wear on the surface, features characterized with the SEM- and the 2D profilometer.The results show that combining SEM- and profilometric methods gives a good picture of the effects of varying the cylinder liner pressure and roughness. The core roughness decreases more for diesel liners than for petrol liners.. A probable cause is that the more severe diesel high pressure run-in conditions are able to effectively “truncate” the plateaux and remove residing plastically deformed un-cut honing residues while the less severe petrol liner conditions do not manage to remove the blechmantel and irregularities to an important extent.

- The demands on decreased environmental impact from vehicles are resulting in a strong push for decreased engine oil and fuel consumption. Engine oil and fuel consumption are to a great extent controlled by the topography of the cylinder liner surface.Recent engine tests have shown a promising reduction in oil consumption when using cylinder liners with a smoother finish than the current plateau honing.One approach to produce smoother liner surfaces is to replace SiC ceramic honing stones with diamond tools. However, event though the diamond honing process results in higher productivity, improved demands of quality control is needed to monitor the degree of cold worked material - “blechmantel” (German), and the resulting risk of increased wear and scuffing.A number of petrol and diesel engine cylinder liners have been mapped to be able to verify the quality and consequences, in terms of wear and function, of the honing process. A new mapping method, combining SEM images and quantitative image analysis with traditional 2D profilometry has been developed and tested in this study. The liners where tested in a reciprocating rig of 8 mm stroke and with a frequency of 10 Hz, simulating the top-dead center conditions in a running engine.The tests where carried out in high- and low pressure conditions with smooth respectively rough liner roughnesses against PVD coated piston rings. The developed surface mapping method was employed before and after the test to study effect of running-in wear on the surface, features characterized with the SEM- and the 2D profilometer.The results show that combining SEM- and profilometric methods gives a good picture of the effects of varying the cylinder liner pressure and roughness. The core roughness decrease more for diesel liners than for petrol liners. In average (rough and smooth liners) the diesel core roughness decrease 265% while the petrol liners average on a 60% decrease. Blechmantel- and Irregularities ratio show a high sensitivity to varying conditions and decrease 1180% to 100% for the diesel liners while the parameters increase between 106% to 18% for all the petrol liners. A probable cause is the more severe diesel high pressure run-in conditions are able to effectively “truncate” the plateaux and remove residing plastically deformed un-cut honing residues while the less severe petrol liner conditions not manage to remove the blechmantel and irregularities in an important extent.

High incidence of disability pension with a psychiatric diagnosis in western Sweden. A population-based study from 1980 to 1998

Tidskriftsartikel (refereegranskat)abstract
- Regional differences in Sweden in the prevalence of disability pension with a psychiatric diagnosis are unexplained, in spite of the significant impact on the population's health, rehabilitation systems, and the health care system. The purpose of this study was to describe the pattern of disability pensions with a psychiatric diagnosis and to analyze the impact of age and gender. We examined the incidencerates in one urban and one semi-rural region and compared these to national rates. The study sample was drawn from employed persons between 16-64 years of age who, because of their sickness insurance coverage, would be eligible to access disability pensions should it be necessary. Analysis of annual incidences and standardized morbidity ratios were made for 1980, 1985, 1990, 1995, and 1998. Data ondisability pension cases were collected from the National Social Insurance registers. In the urban region we found that the proportion of men and women clearly outnumbered the national average: approximately twice the number of persons between 16-64 years of age with apsychiatric diagnosis were receiving a disability pension. In the semi-rural region there were fewer men overall on disability pensionswith psychiatric disorders, but in 1980, 1985, and 1995 women clearly outnumbered men. Access to psychiatric care, unemployment, alcohol dependence, and previous sickness absence are suggested as possible factors that might affect the rates of disability pension in different geographical settings. © 2006 IOS Press.
