- Globally, the demand for energy from renewable sources is growing due to the increasing electricity consumption and the pollution of fossil fuels. The government has framed various policies to facilitate green energy generation, encouraging renewable energy source usage through PV installations in multiple sectors, including educational institutions. The primary objective of this paper is to propose a methodological approach for analysing the performance of the installed PV system on the rooftop of a university building in Tamil Nadu, India. The site selected is favourable for electricity generation from PV systems with an average global solar radiation of 5.82 kWh/m2day. Solar energy changes periodically with annual and daily variations and is not steady due to seasonal changes. The step-by-step performance assessment and the annual performance of the 100-kW solar PV system, which was instituted in 2019, with the forecasted parameters, are presented in this paper. Therefore, the assessment analysis is carried out in four phases: feasibility assessment, Energy yield assessment, Life cycle assessment, and Power quality assessment. To improve the solar PV output and efficiency, considering the solar irradiation, temperature, wind velocity, etc., PV yield is measured to evaluate the PV system's energy metrics. This paper also considers the carbon credits earned, solar power generated in the location, and the payback period. The power quality assessment is carried out in this paper to test the PV plant's compliance with effective grid integration.

- X-chromosomal markers in forensic genetics have become more widely used during recent years, particularly for relationship testing. Linkage and linkage disequilibrium (LD) must typically be accounted for when using close X-chromosomal markers. Thus, when producing the weight-of-evidence, given by a DNA-analysis with markers that are linked, the normally used product rule is invalid. Here we present an implementation of an efficient model for calculating likelihood ratios (LRs) with markers on the X-chromosome which are linked and in LD. Furthermore, the model was applied on several cases based on data from the eight X-chromosomal loci included in the Mentype® Argus X-8 (Biotype). Using a simulation approach we showed that the use of X-chromosome data can offer valuable information for choosing between the alternatives in each of the cases we studied, and that the LR can be high in several cases. We demonstrated that when linkage and LD were disregarded, as opposed to taken into account, the difference in calculated LRs could be considerable. When these differences were large, the estimated haplotype frequencies often had a strong impact and we present a method to estimate haplotype frequencies. Our conclusion is that linkage and LD should be accounted for when using the tested set of markers, and the used model is an efficient way of doing so.

Capturing processes in longitudinal multiple case studies

Tidskriftsartikel (refereegranskat)abstract
- This paper discusses and suggests a methodological approach to capture processes in multiple case studies. While single case studies may address processes in an inductive or abductive manner, multiple case studies entail a stronger need for analytical frameworks and methodological tools developed ex ante in order to maintain focus on the same phenomena across cases and over time. This is, however, difficult to pursue in studies that focus on processes. The aim of the paper is to suggest an approach to longitudinal multiple case studies. We use an example of an on-going multiple case study aiming at capturing the processes of strategizing in terms of how the networking of start-up companies interplays with their ideas of future network positions. The paper concludes by suggesting the use of a combination of narratives and network drawings. Network drawings can be instrumental in capturing the past, the present and the future at different points in time for the individual cases. Based on these descriptions, change patterns and how these evolve can be analyzed and compared across cases and over time.

Explaining incubators using firm analogy

- Incubators are initiated to accelerate the development of new technology-based firms. Policy actors see them as a tool to initiate or revive innovativeness in regions and universities as a way to commercialize research results. However, even though the intended results of the incubator are good it is not known how the incubator should be managed and organized in order to achieve this end. When faced with a new type of organizations analogies can provide insights gathered from other contexts. To contribute to the further understanding of incubators this paper discuss the implications, in terms of highlighted dimensions and further clarifications needed when using the analogy of a firm. The paper uses empirical findings from six incubators. The discussion shows it is not clear who is the actual customer of the incubator. For example, can the policy actors that provide the funding to the incubator be seen as a customer paying for the service of regional revival and the NTBFs customers when their fees are not in relation to the services they are provided? In the discussion it is suggested that the incubator can have many customers with different value creation processes or no customers depending on the viewpoint taken.

Exploring the roles of university spin-offs in business networks

- This paper identifies different university spin-off (USO) roles related to resource interaction among business parties. It does so by mapping how USOs become part of business networks in terms of their roles relative to other parties. The theoretical frame of reference focuses on roles and resource interaction based on an industrial network approach to business markets. The empirical research is based on five cases of USOs representing a variety in terms of technology, degree of newness, sector, and area of application. As a result of the analysis, three different roles are identified: the USO as resource mediator, resource re-combiner and resource renewer. These roles reflect how USOs adapt resources to, or require changes among, business parties' resources. The paper also discusses the main resource interfaces associated with the three roles and related challenges. The paper contributes to previous research through illustrating USOs' roles relative to business parties from a resource interaction point of view, and by pointing to the establishment of new companies in business networks as a way of implementing innovation. Finally, the paper discusses the managerial implications of the research in terms of the USO's need to understand which role to take and how to develop it.

- Assessments and evaluations of incubators has been a topic of discussion for as long as incubators have been in existence due to the fact that there has not been an agreement on how to determine good performance. This paper demonstrates the use of Data Envelopment Analysis (DEA) when studying performance of incubators. More specifically, it does so within the four dimensions of cooperation with universities, business networks, external funding and competence development on a sample of 16 Swedish incubators. We show that DEA enables us to measure non-numerical dimensions, and to simultaneously take into account the efforts made by both the incubator and the outcomes. Moreover, DEA provides benchmarks and, based on a model that divides the incubators into four different groups, illustrates the difference between the benchmark and the incubators' current situation.

Nourishment for the piggy bank : facilitation of external financing in incubators

Tidskriftsartikel (refereegranskat)abstract
- In this paper, we argue that incubators facilitate access to external financing for their incubatees. Incubators use a wide range of activities to facilitate the accessing of external financing from public and private sources. We have grouped these into two sets of activities. The general activities aim to develop the conditions for external financing through information, education of incubatees, network-building and lobbying activities. The specific activities aim to assist the individual incubatee in their pursuit of external finance through help in application procedures, establishing need for capital, making contacts with the best public or private investor, etc. Based on the survey data, we have also shown that it is more common for incubatees to attract external capital compared to non-incubator firms. The incubatees seem especially successful in attracting public capital. The incubatees also attract more private external capital, however, the observed frequency of private capital in the incubatees are low.
