In this paper we will update our 2011–2013 study on the analyses of operational performance of grid connected residential PV systems in the Netherlands and other European countries. We focus on comparing Annual System Yield data from small and medium size installations. If irradiance data is available, Performance Ratio data are compared as well. We employ web scraping techniques to collect a large...
Over the paper decade the health sector has witnessed significant investments towards development of digital health information systems (HIS) infrastructure. Despite the promise and enthusiasm surrounding such efforts, challenges remain regarding how to enhance prospects for long-term maintenance. Observed challenges arise from lack of technical, financial, and human resources. Due to the inadequacy...
Creation and maintenance of a computerized information system that not only manages agricultural field experiments data efficiently but also provides its statistical analysis is essential for researchers, planners and farmers. Generally data created by the researchers is collected, processed and stored in different physical locations and is poorly disseminated. Data is usually retained at the level...
Over time Business Process has become an asset for organization since it allows managing what happens within their environments. It is possible to automate some activities of the business process using information systems and accordingly decrease the execution time and increase the production. However, information systems often suffer maintenance over time and become obsolete and a re-engineering...
In this paper we talk about applying the methods of diversity in cloud based systems for increasing software reliability and fault tolerance. A comprehensive framework was delivered to improve applications in the cloud based system. The improvement is achieved by using diverse redundancy in the framework architecture.
The number of crime incidents that is reported per day in India is increasing dramatically. The criminals today use various advanced technologies and commit crimes in really tactful ways. This makes crime investigation a more complicated process. Thus the police officers have to perform a lot of manual tasks to get a thread for investigation. This paper deals with the study of data mining based systems...
Social media technologies have made it feasible for organizations to tap "wisdom of the crowd" beyond their own workforce. Many organizations use online crowd sourcing contests to find solutions for their business problems. In these contests, self-organized virtual teams compete for monetary reward. Motivated by this phenomenon, this research investigates how the social network structure...
This research analyzes how eSourcing service providers can execute the Information and Communications Technology-enabled international sourcing of software-intensive systems and services (eSourcing) effectively. The extant literature falls short of providing a detailed enough set of best practices and supporting classes of information systems to help providers to manage and deliver effective services...
Herd literature suggests that people tend to discount their own beliefs and imitate others when making adoption decisions. However different people based on their characteristics exhibit different degrees of herd behavior. In the same vein, the characteristics of technology must fit with the requirements of the task that an adopter wants to fulfill Characteristics of individuals and of the technology-to-be-adopted...
Digital initiatives such as big data analytics at Progressive Insurance can drive competitive advantage. However, digital initiatives often fail to meet their objectives in terms of budget, time, or performance. Why is this the case and what can be done about it? Complementing existing studies of software development methodologies, project management techniques, and the role of the CIO, we focus on...
Agriculture Information systems play crucial role in the development of economy of a country. When pest and diseases affect the crops there is a significant decrease in production. Agriculture Information system has been developed by collecting information about pest, diseases, harvesting and plantation. Agile methods are best suited for the development of Information System. In the software industry,...

In 1998 NESMA published an alternative approach to establish the functional size of software enhancement projects. The aim of the approach was to be able to use productivity data from software development to estimate software enhancement. This approach has been highly debated, since it is not a pure functional size measurement method in the ISO/IEC 14143 definition. The approach is in use all over...
The goal of this research is to design the approach to automated development of service-oriented architecture of information systems based on ontology. The approach presented in the paper is based on methodology of system and ontology design. Novelty of the approach is in application of semantic closure of system functions as clustering criteria. The results of the research were used in practice for...
The early detection of leaks in water supply pipelines and water theft prevention is an economically important issue not only for Latvian water utilities. However, monitoring and control of underground infrastructure presents a severe challenge. In recent years, wireless sensor networks are applied for Automated Meters Reading (AMR) and Advanced Metering Infrastructure (AMI). In this paper, authors...
Business operation systems in the design period, not only consider the development of related technologies, but also the selection of different kinds of software platform solutions, such as application server and relational database are particularly important. In addition to the platform operability, cost considerations also affect a large portion of the decision results. If system programmers do...
