Abstract:
Locally manufactured Uninterruptible Power Supply (UPS) units are purchased as an alternative to rolling blackouts and load shedding in underdeveloped and developing countries like Pakistan. These locally manufactured UPS units are energy-inefficient, causing stress on the national grid and cost-intensive for the residential consumer in the form of high utility bills of electricity. In this regard, the authors have proposed the PV fed local UPS inverter to make the existing UPS unit more efficient through photovoltaic (PV) energy without disrupting its function of providing uninterrupted suppl

Abstract:
Cleaner and greener energy sources have proliferated on a worldwide basis, creating distributed energy systems. Given the unreliable nature of the renewable sources such as solar and wind, they are traditionally based on inverters interfaced with legacy AC grid systems. While efficiency, output waveform quality and other technical specifications of inverters keep improving gradually, only limited attention is given to widening the input range of inverters. This paper presents a new supercapacitor assisted (SCA) technique to widen the input range of an inverter without modifying the inverter it

Abstract:
In this paper, different control approaches for grid-forming inverters are discussed and compared with the grid-forming properties of synchronous machines. Grid-forming inverters are able to operate AC grids with or without rotating machines. In the past, they have been successfully deployed in inverter dominated island grids or in uninterruptable power supply (UPS) systems. It is expected that with increasing shares of inverter-based electrical power generation, grid-forming inverters will also become relevant for interconnected power systems. In contrast to conventional current-controlled in

Abstract Though there are many strategies to control single-phase uninterruptible power supply (UPS) inverters, they suffer from some drawbacks, the main being complexity. This paper proposes a simple dual-loop controller for the single-phase UPS inverter with the LC filter. The suggested control scheme uses the capacitor current as the feedback signal in the inner current loop. No fictitious phase generation or reference frame transformations are required, and simple proportional gains are employed as both voltage and current regulators.

Abstract:
In this paper, the finite control set model predictive control (FCS–MPC) technique-based controller is proposed for the inverter of the uninterrupted power supply (UPS) system. The proposed controller uses the mathematical model of the system to forecast the response of voltage for each possible switching state for every sampling instant. Following this, the cost function was used to determine the switching state, applied to the next sampling instant. First, the proposed control strategy was implemented for the single inverter of the UPS system. Finally, the droop control strategy was implemen

Abstract:
This chapter will discuss how Discovery either reproduces, criticizes, or subverts established U.S. representations of diplomacy. The results will provide some leads on whether Discovery lives up to Star Trek’s progressive worldview. Revisiting Iver B. Neumann’s argument, this chapter argues that Discovery’s pilot episode can be viewed as a critical reflection on how the difference between idealist (“We come in peace”) and realist (a “Vulcan Hello”) approaches to diplomacy become blurred from the inverted perspective of the (Klingon) Other. However, over the further course of the season, Discovery loses its reflexive perspective on the ambiguity of diplomacy and settles for demonstrative idealism. The chapter discusses whether Discovery in its adaptation of a demonstrative ‘idealism’ subverts U.S. representations of diplomacy in the light of paradigmatic shifts after 9/11, or whether it reproduces the ambiguity of ‘realist’/’idealist’ representations, ultimately legitimizing the use of force for supposed higher ends.

This chapter begins with a discussion of the use of interest rates in asset valuation. During the Great Recession, the Federal Reserve has navigated U.S. interest rates lower by first reducing the target for the federal funds rate to zero, and then engaging in a process of quantitative easing by purchasing longer-term securities. The effect of the Federal Reserve's actions has been to lower interest rates that affect valuation models across all assets and investments. The chapter then discusses interest rate yield curve, covering the types of yield curves, why the yield curve may be flat or inverted, the increase in market demand for long-term securities, and long-term yield affected by Federal Reserve monetary policy.

Abstract:
An iterative method of solution of a nonlinear inverse problem of gravimetry on the basis of the joint application of several cards of the measured field and several vectors of entry conditions for depths up to blocks of rocks in one iteration is developed. Examples of the interpretation of the gravitational field measured in the Western Krivbass are given.

Abstract:
Review question / Objective: A meta-analysis was performed to investigate prognostic value of ASXL1 mutations in patients with myelodysplastic syndromes and acute myeloid leukemia. Condition being studied: Some MDS or AML patients have ASXL1 mutations while others haven’t. Main outcome(s): We used OS as the primary endpoint and AML transformation as the secondary endpoint. OS was defined as either death (failure) or survival at the last follow-up. AML transformation was defined as starting when the patient entered the trial and proceeding to the time of AML diagnosis.Combined HRs and 95% CIs f

Abstract:
The objectives of this study were to investigate soil-pneumatic tire interaction and develop traction-soil compaction prediction model. We have developed an inverse solution technique that employs a response surface methodology to determine engineering properties of soil in-situ. This technique is useful in obtaining actual properties of soil in-situ for use in traction and soil compaction studies rather than using the values obtained in the laboratory by employing remolded and/or disturbed soil samples. We have conducted extensive field tests i the U.S. to develop semi-empirical traction pred

Abstract:
There is very little evidence that trade facilitation measures have a significant impact on carbon emissions, except in the case of trucks at land border crossings, where there is good evidence that trade facilitation can lead to significant reductions in emissions. There is good evidence that trade facilitation measures at land border crossings can reduce traffic congestion and waiting times for trucks, but only limited evidence of the impact of these improvements on carbon emissions. Computer models of inspection stations at the USA-Mexico border suggest that improving the efficiency of land

Abstract:
When Hurricane Harvey hit the Texas coast as a category 4 hurricane on August 25, 2017, it resulted in $125 billion in damage, rivaling only Hurricane Katrina in the amount of damage caused. It also resulted in the deaths of 88 people and destroyed or damaged 135,000 homes. Much of that devastation was the result of flooding. The storm dumped over 27 trillion gallons of rain over Texas in a matter of days. Some parts of Houston received over 50 inches of rainfall. The potential liability that dam and reservoir operators may face for decisions they make during storm and flooding events has now

Abstract:
In the early morning on the 4th of August 2014, a tailings dam near Quesnel, BC burst, spilling approximately 25 million m3 of runoff containing heavy metal elements into nearby Quesnel Lake (Byrne et al. 2018). The runoff slurry, which included lead, arsenic, selenium, and vanadium spilled through Hazeltine Creek, scouring its banks and picking up till and forest cover on the way, and ultimately ended up in Quesnel Lake, whose water level rose by 1.5 m as a result. While the introduction of heavy metals into Quesnel Lake was of environmental concern, the additional till and forest cover scour
