We begin our excursion into the field of data conversion by reviewing the most frequently applied conversion principles. The next section explains the fundamentals of delta-sigma modulation. This paves the way for the section which provides a case study of a delta-sigma based high-resolution ADC system intended for a sonar application. This design example not only illustrates the various trade-offs on the architectural level but also addresses practical implementation issues on the physical level. Finally, the last section summarizes our findings and contains some concluding remarks.

The Vistula Lagoon

Abstract In recent years the transition of marine navigation to the digital era has been gaining momentum. Implementation of e-Navigation solutions varies from country to country in terms of their priorities, goals, levels and effects. Maritime authorities in Poland have been setting the pace in this transition process, not only in Poland but also in general as a global solution. The most recent example is the planned deployment of a variety of e-Navigation tools in the Vistula Lagoon: from GNSS-RTK Ground-Based Augmentation System, to virtual and synthetic aids to navigation, high-resolution bathymetry and advanced navigational software for piloting. The major objectives of this paper are, first, to summarise recent dynamics in the e-Navigation field, and second, to present a practical implementation of the e-Navigation concept in the Vistula Lagoon area.

This aims to review and analyze the Jordanian experiment in the developmental regional planning field within the decentralized managerial methods, which is considered one of the primary basic provisions for applying and success of this kind of planning. The study shoed that Jordan has passed important steps in the way for implanting the decentralized administration, but these steps are still not enough to established the effective and active regional planning. The study reveled that there are many problems facing the decentralized regional planning in Jordan, despite of the clear goals that this planning is trying to achieve. These problems have resulted from the existing relationship between the decentralized administration process’ dimensions from one side, and between its levels which ranged from weak to medium decentralization from the other side, In spite of the official trends aiming at applying more of the decentralized administrative policies, still high portion of these procedures are theoretical, did not yet find a way to reality. Because any progress or success at the level of applying the decentralized administrative policies doubtless means greater effectiveness and influence on the development regional planning in life of the residents in the kingdom’s different regions. So, it is important to go a head in applying more steps and decentralized administrative procedures, gradually and continuously to guarantee the control over any negative effects that might result from Appling this kind of systems.   © 2018 JASET, International Scholars and Researchers Association

This study analyzes the English teacher candidate’s use of instructional media in the teaching practicum. The English teacher candidate who became the participant in this study was doing their teaching practicum in MTsN 5 Jember. This study applied the qualitative case study design. Interview and observation were done one time to select the participant. The four-times classroom observations and questionnaires were used in order to collect the data. This study employed the model of Creswell in analyzing the data. The findings of this study showed that the English teacher candidate applied one type of instructional media namely Visual Media. Those were Picture and Whiteboard. The way the teacher candidate implemented the instructional media was almost the same in each meeting of the teaching and learning process. However, the students’ participation and response were not always the same in every meeting. It depended on the way the teacher candidate managed the class activity.

The chapter discusses management consultants and consulting knowledge in health care, highlighting significant expenditure on consultancy and how consultants have shaped thinking in public services, which some critics suggest has served consultants’ own (financial) interests. The chapter then discusses the way consultants mobilize management knowledge and frame clients’ problems and solutions. It discusses an empirical case study of a consultancy project to redesign NHS organizations to make substantial ‘efficiency savings’. Here, consultants framed the NHS’s problem and solution, and then imposed an organizational redesign. Local NHS managers and clinicians framed the NHS’s problem differently, doubting the consultants’ framing and proposing redesign, but feeling unable to engage in dialogue about these concerns. Consequently, they engaged with the project in a calculated and defensive way, superficially accepting the redesign while waiting for its implementation to fail. Thus, the chapter demonstrates framing politics surrounding management consulting knowledge.

Finite Planning Horizon

Abstract This paper describes the optimization of preventive maintenance (PM) over a finite planning horizon in a semi-Markov framework. In this framework, the asset may be operating, and providing income for the asset owner, or not operating and undergoing PM, or not operating and undergoing corrective maintenance following failure. PM is triggered when the asset has been operating for τ time units. A number m of transitions specifies the finite horizon. This system is described with a set of recurrence relations, and their z-transform is used to determine the value of τ that maximizes the average accumulated reward over the horizon. We study under what conditions a solution can be found, and for those specific cases the solution τ* is calculated. Despite the complexity of the mathematical solution, the result obtained allows the analyst to provide a quick and easy-to-use tool for practical application in many real-world cases. To demonstrate this, the method has been implemented for a case study, and its accuracy and practical implementation were tested using Monte Carlo simulation and direct calculation.
