IGOE IoT framework for waste collection optimization

Waste management has become a major issue in all the part of the world and tends to grow day by day. Mismanagement in waste has become one of the key environmental and health issue. With the increase of population, especially in the urban areas waste collection, categorization, and disposal has become a major hazard for the government authorities. An IoT based waste collection framework is proposed to automate the solid waste identification, localization and collection process. The authors are involved in the identifying key impact factors in the waste collection process and provide systematic and automated solution to optimize the process to achieve higher efficiency. A layered architecture is introduced to handle the waste collection process and an optimization algorithm is derived for the existing business process based on the proposed evaluation criteria. The final outcome is a complete framework which compromises the Inputs, Outputs, Guide and Enables. The main objective is to implement an optimized automated waste collection system with the use of a vast sensor network capable of gathering waste data and by implementing an optimization algorithm in waste collection.

A database optimization model with quantitative benchmark

Query optimization and indexing have an immense impact on database optimization. This has been considered in many different perspectives which provide several different solutions in each case. The purpose of this paper is to primarily provide a comprehensive review and discussion of the core problems through the research on query optimization technology and indexing, based on a number of optimization techniques commonly used in the general approach of a query. A new database optimization model is designed and experiments show that this model can significantly reduce the amount of query execution time to improve the optimization efficiency. Regardless of research on the database optimization model, significant work has been done to comparatively evaluate three scenarios; non-optimized query, optimized query without following any optimization standard, and optimized query via proposed optimization model using the same experimental methodology. Further, this paper describes a benchmark that was developed specifically for the purpose of measuring the quantitative evaluations of the proposed database optimization model.

A framework for Business Process Re-engineering to reduce the number of processes - a case study of National Blood Transfusion Services

Blood Donation and Blood Transfusion Services play a vital role in saving peoples lives. It is a known concern that the blood donation process usually consumes a lot of time and effort from both donors and medical staff. This issue is present, mainly due to the absence of a concrete and precise information system. If such a systems is implemented it could have the ability to allow donors and blood donation centers to communicate efficiently and collaborate with each other to minimize the time and effort required for the blood donation process. Besides, most blood banks work in isolation and are not integrated with other blood donation centers, which affect and degrade the quality of overall blood donation and blood transfusion services. This work aims at developing a standard framework named as “One Blood” based on business process re-engineering concepts, cloud storage services, and web application development technologies. This paper comprehensively describes the conceptual framework based on a case study of National Blood Transfusion Services in Sri Lanka. As a result, several pitfalls, highly critical processes, and points of failure were identified, which needs to be redefined. Improving the workflows and organizing the processes was conducted by the application of BPR concepts followed by the proposed framework. To further amplify the application of BPR two additional verticals namely Process Re-Organization and Radical Redesign was aligned with the Process Re-engineering phase. Process Re-Organization performs the comparing and contrasting of manual and systematic approaches while Radical Redesign enables the chance to leverage IT related technologies to achieve integration and automation of processes. The outcome of this research was presented as a cloud-based centralized web solution for the NBTS using the One Blood System by the integration of all of these concepts and technologies.
