Improving Regulatory Performance: Does Executive Office Oversight Matter?
No full textExecutive Office review and oversight of proposed federal regulations have been a bipartisan action of presidents and some governors. Proposals for regulatory improvement regularly highlight the role of benefit-cost analysis in this process. Supporters argue that the purpose of a benefit-cost review is to improve the social (net) benefits of implemented regulations. The evaluation question is whether Executive Office review has actually improved performance. This paper uses information on the status of regulations and their estimated economic impact to determine if Executive Office review has changed the outcome in different Administrations. The study is based on cost-effectiveness data that have had a large role in the debate about regulation and while an extensive critique of the data exists, its issues are addressed. The results indicate that while Executive Office review is associated with rejecting some regulations that would have been economically inefficient, such review appears to have no efficiency improving impact on the difference between proposed and final regulations or on the cost effectiveness of regulations that are implemented.
Performance Analysis of Farrow Structure Based FBMC-OQAM System
No full textAbstractFarrow structure is used in the efficient implementation of high order filters. The number of unknown coefficients is much less in Farrow structure based implementation, in comparison with the direct form implementation of FIR filters. Some predefined multipliers can also be used in this method. Since they are known apriori they will not add much to the complexity of the system. It is seen that a relatively strong correlation exists among the adjacent impulse response coefficients of the frequency selective filters. This fact is exploited in the Farrow structure to reduce the number of multipliers required for the implementation of desired filter. And these Farrow coefficients are used for representing the polyphase components of the desired filter. This Farrow structure based prototype filter is used for implementing an FBMC-OQAM system. BER performance of Farrow structure based FBMC-OQAM system is studied and found comparable with that of existing FBMC-OQAM system

A Typology for OER Business Models
No full textThis paper provides an update on activity in the innovation and business models strand of the ENCORE+ project. A range of business models that support or draw on open educational resources (OER) have been proposed. This paper reviews models that have been proposed (Tlili et al., 2020; Padilla Rodriguez et al., 2018; Belleflamme & Jacqmin, 2015; Ubachs & Konings, 2016; and Farrow, 2019) and suggests a synthesis into one typology of OER business models. The ENCORE+ OER Business Model Typology has been developed as part of a wider effort to understand and evaluate economically sustainable approaches to OER as well as to formulate OER value propositions for different stakeholders. In related work, a range of OER innovation case studies (N=48) are being prepared for publication. These will illustrate different instances of innovation with OER and show how OER actors understand their value proposition to different audiences
Farrow-based true time-delay FPGA wideband digital beamforming architecture
No full textThis paper presents a flexible FPGA digital beamforming architecture to steer an array for wideband radio frequency signals. The architecture combines True Time-Delay (TTD) units and phase-shifting to beamform at digital baseband. The TTDs utilize low order, coefficient-symmetric Farrow structures to rapidly and flexibly adjust fractional sample delays applied to wideband signals with minimal FPGA resources. Bandpass sampling is employed to further reduce resource and power consumption. The designed Farrow structure’s group delay and magnitude characteristics are evaluated. Measured beam patterns are demonstrated through simulation of the proposed FPGA receive array using fixed-point arithmetic. The multiplier utilization of the proposed system is estimated and compared with the literature. Promising results open discussions to hardening Farrow structure cores on FPGAs to serve multiple signal processing techniques required in future communications systems without consuming programmable logic fabric
Highly Efficient Photoluminescence and Lasing from Hydroxide Coated Fully Inorganic Perovskite Micro/Nano Rods
No full textThis is a micro-photoluminescence(micro-PL) based study to investigate the optical property of surface passivation effect with Pb(OH)2 coated CsPbBr3 micro/nano rods and demonstration of stimulated emission from defect states. We also presented a technique with completely separable excitation and collection in a confocal microscopy. In this work, we have supported with data from time-resolved study, time-integrated PL map and scan with either collection/excitation fixed and scanning the other
