- After the introduction of information technology (IT), the government needs to take the initiative to start IT projects for the automation of government process to the citizen. Statistics show that a high number of government IT projects fail and only 15 percent e-government projects are successful. In this study, we will answer this research question, what are the reasons for failure of IT projects in the government sector organization in Pakistan and how to overcome these issues? This research was conducted through a literature review, 20 articles from journals and conferences were selected through keywords for the period of ten years from 2003 to 2013. For suggestions, we have followed the same structured search procedure. We found and select articles with our keywords, after reading abstract and conclusion. Our study has described four factors for the failure of IT projects in government sector organizations in Pakistan. These factors are Technology, Management, Politics and Finance. The technology factor can be reduced by providing latest ICT infrastructure with an expert to run and maintain it. Management issues can be resolved by hiring an experienced, skilled and highly motivated project manager to complete a project successfully. Government should make new laws and regulations to help the implementation of these projects and bureaucracy should eliminate any power struggle during and after the implementation. The budget should be allocated before the start of the project to complete it on time. Our research study has provided guidelines to policy makers for automation of government organizations in Pakistan. By considering these suggestions, successful government projects can be achieved.

- Abstract. In addition to 9 vowel and 18 consonant phonemes, Swedish has three prosodic phonemic contrasts: word stress, quantity and tonal word accent. There are also examples of distinctive phrase or sentence stress, where a verb can be followed by either an unstressed preposition or a stressed particle. This study focuses on word level and more specifically on word stress and tonal word accent in disyllabic words. When making curriculums for second language learners, teachers are helped by knowing which phonetic or phonological features are more or less crucial for the intelligibility of speech and there are some structural and anecdotal evidence that word stress should play a more important role for intelligibility of Swedish, than the tonal word accent. The Swedish word stress is about prominence contrasts between syllables, mainly signaled by syllable duration, while the tonal word accent is signaled mainly by pitch contour. The word stress contrast, as in armen [´arːmən] ‘the arm’ - armén [ar´meːn] ‘the army’, the first word trochaic and the second iambic, is present in all regional varieties of Swedish, and realized with roughly the same acoustic cues, while the tonal word accent, as in anden [´anːdən] ‘the duck’ - anden [`anːdən] ‘the spirit’ is absent in some dialects (as well as in singing), and also signaled with a variety of tonal patterns depending on region. The present study aims at comparing the respective perceptual weight of the two mentioned contrasts. Two lexical decision tests were carried out where in total 34 native Swedish listeners should decide whether a stimulus was a real word or a non-word. Real words of all mentioned categories were mixed with nonsense words and words that were mispronounced with opposite stress pattern or opposite tonal word accent category. The results show that distorted word stress caused more non-word judgments and more loss, than distorted word accent. Our conclusion is that intelligibility of Swedish is more sensitive to distorted word stress pattern than to distorted tonal word accent pattern. This is in compliance with the structural arguments presented above, and also with our own intuition.

What affects recognition most – wrong word stress or wrong word accent?
- 2015

Konferensbidrag (refereegranskat)abstract
- In an attempt to find out which of the two Swedish prosodic contrasts of 1) word stress pattern and 2) tonal word accent category has the greatest communicative weight, a lexical decision experiment was conducted: in one part word stress pattern was changed from trochaic to iambic, and in the other part trochaic accent II words were changed to accent I. Native Swedish listeners were asked to decide whether the distorted words were real words or ‘non-words’. A clear tendency is that listeners preferred to give more ‘non-word’ responses when the stress pattern was shifted, compared to when word accent category was shifted. This could have implications for priority of phonological features when teaching Swedish as a second language.

The role and interaction of microgrids and centralized grids in developing modern power systems
- 2017
-
Konferensbidrag (refereegranskat)abstract
- An extension of microgrids is now underway, primarily to allow increased electrification in growing economies but also to meet the need to reduce global CO2 emissions and to provide ancillary services to centralized grids. Energy access constitutes one of the fundamental building blocks for economic growth as well as social equity in the modern world. Access to sustainable energy is needed to achieve sustainable development. A microgrid should not be seen as a competitor to the centralized grid but as a complement.Through examination of several implemented cases from different parts of the world the following topics are considered: Analysis of the interaction between centralized grids and microgrids Analysis of stakeholder decision parameters for electrification Analysis of design differences and requirements for microgrids, depending on the intended purpose and the need of the end customer.It is determined that good planning, suitable requirements and clear regulations for microgrids (in relation to centralized grids) limits the risk of stranded assets and enables better business cases for the involved stakeholders.The paper is based on the discussion paper The role and interaction of microgrids and centralized grids in developing modern power systems – A case review publiced by ISGAN (International Smart Grid Action Network) Annex 6: Power T&D Systems.The discussion paper and further information about ISGAN is available at http://www.iea-isgan.org/.

A review of Parkinson’s disease cardinal and dyskinetic motor symptoms assessment methods using sensor systems
- 2016
-
Konferensbidrag (refereegranskat)abstract
- This paper is reviewing objective assessments of Parkinson’s disease(PD) motor symptoms, cardinal, and dyskinesia, using sensor systems. It surveys the manifestation of PD symptoms, sensors that were used for their detection, types of signals (measures) as well as their signal processing (data analysis) methods. A summary of this review’s finding is represented in a table including devices (sensors), measures and methods that were used in each reviewed motor symptom assessment study. In the gathered studies among sensors, accelerometers and touch screen devices are the most widely used to detect PD symptoms and among symptoms, bradykinesia and tremor were found to be mostly evaluated. In general, machine learning methods are potentially promising for this. PD is a complex disease that requires continuous monitoring and multidimensional symptom analysis. Combining existing technologies to develop new sensor platforms may assist in assessing the overall symptom profile more accurately to develop useful tools towards supporting better treatment process.
