This paper proposes a low-voltage ridethrough (LVRT) capability for a doubly-fed induction generator (DFIG) wind turbine (WT) system. With the proposed method, series grid-side converter (SGSC) in which its DC-side connected at the DC bus of the back-toback converters and its AC-side connected in series with line through transformer have been applied, enables to compensate a voltage response of the system during the grid faults and to reduce the capital cost.

Graphene-based electrode materials exhibit a high specific capacitance and long charge-discharge cycling life, but the material cost remains high because of the complexity of the graphene manufacturing process. This study employed an electrochemical exfoliation method to prepare graphene in a simple and ecologically friendly procedure. According to research findings, the disordered multi-layer structure of graphene exhibited great purity, porosity, and graphitization.

Pwo DNA polymerase is an enzyme that is widely used in PCR due to its thermal stability and proofreading activity (3′-5′ exonuclease activity) with high accuracy. Optimizing the expression and purification of the protein is crucial to reducing the cost of production for this important enzyme. In this study, the higher expression level of the gene encoding Pwo DNA polymerase in bacteria strain E. coli BL21(DE3) was achieved by optimizing codon usage.

The aim of this Masters of Engineering (MEng) - Aerospace thesis was to investigate the durability of Piezoelectric Wafer Active Sensors (PWAS) for the health monitoring of composite structures. One significant challenge faced by the aviation industry is the cost and time associated with maintaining aircrafts, in particular, aging airliners. Structural Health Monitoring (SHM) is a possible approach to reduce the high cost of inspection and maintenance.

The world is becoming increasingly focused on an imperative to reduce the cost of services. Managers at this cutting edge of practical organizational development are trying many ways to achieve this. The major focus of this research uses a systems psychodynamic approach to investigate the role taken up by part-time contract managers in an Australian university. These part-time roles frequently fail in the longer term. This approach provides an understanding of the unconscious group dynamics that may cause the role to fail.

Enterprise Resource Planning (ERP) system is one of the most popular forms of IT for businesses at present. Deriving from efforts to rationalize lead times and possession stock costs, the 80’s manufacturing resource planning (MRP II) is developed into ERP system considered as the standard that integrates business processes throughout the organization, which in turn enhances operational efficiency (Akkermans, Bogerd, Yücesan, & Van Wassenhove, 2003; Davenport, 1998). Callaway (1999) states that the ERP system promises to achieve benefits in both tangible (e.g.

A green and simple approach has been successfully developed to synthesize chitosan/Ag nanocomposites using kumquat extract as a biological reducing agent. It indicates to be an ecofriendly and green method for the synthesis providing a cost effective and an efficient route for the chitosan/Ag nanocomposites’ synthesis. The prepared chitosan/Ag nanocomposites have been characterized by UV-vis, TEM, FTIR, and XRD. Result showed those chitosan/Ag nanocomposites have been obtained with average particle size ~15-25 nm.

Our study investigates how ultimate ownership structure and the corporate tax rate affect the equilibrium trade-off relation between manager ownership and debt in reducing agency costs. Considering the presence of the controlling shareholder, we find that higher corporate tax rates strengthen the trade-off relation between manager ownership and debt while higher control rights held by the controlling shareholder weaken it as well as the strengthening effect of corporate tax rate.

Harrison's Internal Medicine Chapter 26. Confusion and Delirium Confusion and Delirium: Introduction Confusion, a mental and behavioral state of reduced comprehension, coherence, and capacity to reason, is one of the most common problems encountered in medicine, accounting for a large number of emergency department visits, hospital admissions, and inpatient consultations. Delirium, a term used to describe an acute confusional state, remains a major cause of morbidity and mortality, contributing billions of dollars yearly to health care costs in the United States alone.

The primary business rationale for offshoring has been to reduce IT operating and infrastructure costs. The cost savings from offshore outsourcing increase with the percentage of total development effort outsourced and the percentage of work performed offshore. They are maximized when the entire development is outsourced and all the work is performed overseas.

Data compression is the technique to reduce the redundancies in data representation in order to decrease data storage requirements and, hence, communication costs when transmitted through a communication network [24, 25]. Reducing the storage requirement is equivalent to increasing the capacity of the storage medium. If the compressed data are properly indexed, it may improve the performance of mining data in the compressed large database as well
