The purpose of this article is to propose and evaluate a novel system architecture for Smart City applications which uses ontology reasoning and a distributed stream processing framework on the cloud. In the domain of Smart City, often methodologies of semantic modeling and automated inference are applied. However, semantic models often face performance problems when applied in large scale.
The problem domain is addressed by using methods from Big Data processing in combination with semantic models. The architecture is designed in a way that for the Smart City model still traditional semantic models and rule engines can be used. However, sensor data occurring at such Smart Cities are pre-processed by a Big Data streaming platform to lower the workload to be processed by the rule engine.
By creating a real-world implementation of the proposed architecture and running simulations of Smart Cities of different sizes, on top of this implementation, the authors found that the combination of Big Data streaming platforms with semantic reasoning is a valid approach to the problem.
In this article, real-world sensor data from only two buildings were extrapolated for the simulations. Obviously, real-world scenarios will have a more complex set of sensor input values, which needs to be addressed in future work.
The simulations show that merely using a streaming platform as a buffer for sensor input values already increases the sensor data throughput and that by applying intelligent filtering in the streaming platform, the actual number of rule executions can be limited to a minimum.

Marketing - value proposition and value delivery, switching cost, customer acquisition and retention, positioning, pricing, distribution and retailing, role of trust and transparency to build sustainable relationship in B2B context, and efficient service delivery.
Undergraduate and graduate students in marketing, business administration, strategy, retailing, B2B marketing, services marketing and general management courses. Also, it can be used for executive management/training programmes.
The case focuses on an existing scenario of a natural gas business in Gujarat, India, in order to provide understanding of marketing challenges, especially in the B2B context, faced by organisations in this evolving business environment. The case examines the strategies and policies implemented by the company and their impact on the customer. The case presents reactions and responses from the concerned customers. The case illustrates the criticalness of understanding customer expectations and designing and delivering customer centric strategies to sustain market leadership in an evolving and competitive market.
Expected learning outcomes
The case study enables the students to understand and analyse: the current business environment; the important factors impacting natural gas business; economic analysis of energy; opportunity and challenges for doing cleaner and greener business; role of cleaner fuel to reduce carbon footprint; and carbon credit impacting top line and bottom line of a customer. The case provides students the opportunity to understand and analyse the importance of switching costs to acquire a new customer; and devising and implementing marketing strategies to expand customer base and enter into new territories.

The purpose of this paper is to assess the financial sustainability of Islamic Saving Credit Corporative Society (SACCOS) and the factor(s) affecting their financial sustainability in the Tanzanian context.
The data set used in this study comes from four SACCOS audited financial reports from the year 2010 to 2014 and from interviews with SACCOS’s management.
The study found that the IMFIs in Tanzania are not financially sustainable. Additionally, having responsible staff members, regular review of financial guidelines, education to members, cooperation between employees and management and staff training are found to be highly contributing factors towards SACCOS’s financial sustainability. Moreover, the findings reveal that depending on the single source of income, i.e., charges on members contributed much in these SACCOS’s not being financially sustainable.
Only two available registered Islamic SACCOS was used. Additionally, conventional SACCOS have been in service provision for a long time as compared to Islamic ones; hence, caution must be taken for comparison purposes.
Based on these findings, the Islamic SACCOS needs to initiate productive projects that can enable them to have other income sources apart from charges on members.
This study traces the financial trend of Islamic SACCOS in Tanzania since its establishment in 2010. Such trace enables Islamic SACCOS and other stakeholders to be aware on the financial progress of Islamic SACCOS and act accordingly to ensure sustainability.
