Background: Hyperspectral image analysis is a fast and non-destructive technique that is being used to measure quality attributes of food products. This research investigated the feasibility of predicting internal quality attributes, such as Total Soluble Solids (TSS), pH, Titratable Acidity (TA), and maturity index (TSS/TA); and external quality attributes such as color components (L*, a*, b*)...

New technology is continuously proposed in the printing technology, and as a result the need to perform quality assessment is increasing. Subjective assessment of quality is tiresome and expensive, the use of objective methods have therefore become more and more popular. One type of objective assessment that has been subject for extensive research is image quality metrics. However, so far no on...

Modern software operates in highly dynamic and often unpredictable environments that can degrade its quality of service. Therefore, it is increasingly important having systems able to adapt their behavior. However, the achievement of software adaptability can influence other software quality attributes, such as availability, performance or cost. This paper proposes an approach for analyzing tra...

This paper addresses the need for a manageable method of evaluating the overall image quality of hardcopy output from printer systems so that the systems can be compared in a meaningful way. Image quality metrics are widely used and are very objective, but are unsuitable for this purpose because there is no good way of extracting overall image quality from the large number of possible metrics. ...

E-commerce is considered an excellent alternative for companies to reach new customers. However, many e-commerce websites have a short life because they don’t meet the minimal software quality requirements. To help the development of quality e-commerce websites, this work identifies and ranks the main quality attributes to this application domain. The survey of the attributes was based on the s...

In an earlier column, I compared the roles of a software architect and a traditional building architect. I suggested that this oftenused analogy may not be entirely accurate, and that there may be a more precise analogy available to us in the emerging field of architectural engineering. In a subsequent release of SEI Interactive, Rick Kazman continued contrasting software architecture and “trad...

The group of attributes (characteristics, requirements) related to green software is essential part of software quality model. It consists of the two main attributes as a resources (energy) saving and sustainability. Evolution of software quality models is analyzed in context of green and reliability. In particular, well known software quality models beginning from on the first McCall’s model (...

PURPOSE Health workers have numerous concerns about hospital IS (HIS) usage. Addressing these concerns requires understanding the system attributes most important to their satisfaction and productivity. Following a recent HIS implementation, our objective was to identify priorities for managerial intervention based on user evaluations of the performance of the HIS attributes as well as the rela...

Recent meat demand models incorporate demand functions for cuts of meat rather than whole carcasses. However, parameters for “meat quality” are seldom included in such models. Modelling difficulty arises as meat cuts are heterogeneous in their quality attributes. Meat quality may be assessed by measurement of attributes including tenderness, juiciness and flavour. Cooking method and cooking tim...
