We present issues and solutions concerning the calibration and validation of ENVISAT ASAR image products – both their geometry and radiometry are investigated. Concerning geometric calibration, the slant range products (IMS, APS) offer the best available resolution. We tabulate differences between measured (in image products) and predicted (via geodetic position, precise state vectors, and rang...

Methods of web data mining can be divided into several categories according to a kind of mined information and goals that particular categories set: Web structure mining (WSM), Web usage mining (WUM), and Web Content Mining (WCM). The objective of this paper is to propose a new WCM method of a page relevance ranking based on the page content exploration. The method, we call it Page Content Rank...

Because land-applied organic amendments (manures and biosolids) have widely differing susceptibilities to phosphorus (P) solubilization by water, total P (TP) content is an unreliable indicator of their potential to impact water quality. While P can be transported by erosion of Penriched soil particles, much research has addressed P loss to surface runoff and subsurface drainage in the form of ...

Often data in multi-criteria decision making (MCDM) problems are imprecise and changeable. Therefore, an important step in many applications of MCDM is to perform a sensitivity analysis on the input data. This paper presents a methodology for performing a sensitivity analysis on the weights of the decision criteria and the performance values of the alternatives expressed in terms of the decisio...

This article responds to “Taking the Work System Theory Forward” (Niederman and March, 2014), a JAIS research perspective article about an article on work system theory (Alter, 2013e). The research perspective article recognizes value in the work system approach, suggests that WST is not a proper theory, and suggests areas for related theory development. After summarizing the main ideas in WST,...

Mixed model assembly lines (MMAL) are a type of production line where a variety of product models similar in product characteristics are assembled. The effective design of these lines requires that schedule for assembling the different products is determined. In this paper we tried to fit the sequencing problem with the main characteristics of make to order (MTO) environment. The problem solved...

Abstract Sustainable development is based on environmental, social, economic, and technical dimensions. In this study, the sustainability of wastewater treatment techniques in urban areas Iraq was assessed using a multi-criteria decision analysis (MCDA)/the weighted sum model (WSM). The performed 13 operating plants 10 provinces, Iraq, questionnaire sheet with assistance 52 specialists Ministry...

This study presents a thorough analysis of the electronic structures TaPxAs1−x series compounds, which are significant interest due to their potential as topological materials. Using combination first principles and Wannier-based tight-binding methods, this investigates both bulk surface compounds for varying compositions (x = 0, 0.25, 0.50, 0.75, 1), with focus on properties. By using chiralit...

Often, data in MCDM problems are imprecise and changeable due to the mandatory participation of human judgement, which is often unclear vague. Hence, selection an appropriate method crucial optimal decision-making. All methods heavily affected by individual or group preferences therefore even a small change can cause rank-reversal. With regular proliferation such their modifications, it importa...
