The RNA molecule is capable of folding into different shapes, with some being more stable than others. The structural space of the RNA can be described by Stochastic Context-free Grammars (SCFG), offering a probabilisitic distribution of structural scenarios. In a more accurate folding model, the probability associated with a structural scenario is more informative of its stability. Here, we offer two different ways of calculating the Shannon Entropy of the SCFG-modeled RNA structural space; Grammar Space (GS) Entropy and SCFG Entropy. The former is the Shannon Entropy of the infinite number of structures produced by the model and the latter is the Shannon Entropy of a limited subset of structures all of which belong to the same RNA sequence. After a brief introduction on the two measures, we explore the relationship between these measures on a given set of RNA folding models and biologically functional RNA sequences. We show that these two measures of entropy are indeed correlated. While more theoretical work is needed in understanding the convergence behavior between the two, this observation suggests that GS Entropy is a promising characteristic in future model training approaches.

The purpose of this study is to understand how academics and practitioners alike define and discuss user experience (UX). There are many academic and practitioner definitions of UX design, but there is not presently a universally accepted definition either theoretically or practically. How will colleges and universities prepare students for this nebulous professional field?

Next-generation wireless devices use many coherent antennas to enhance wireless performance at the expense of size, weight, power, cost, and complexity. This has caused many multiantenna signal processing architectures to be unfit for deployment on unmanned aircraft. Recent advances in FPGA technology have reduced the footprint of a 16 antenna signal processor to a feasible size for unmanned aircraft. We are exploring the capabilities of this new technology by demonstrating an adaptive beamformer spatial filtered GPS system. The multiantenna implementation will increase the quality of GPS services and provide resistance to multipath and adversarial spoofing. This paper documents early progress in developing and verifying the firmware for the future demonstration.

In this paper, we aim to analyze and build upon a framework cloud computing environments based on our previous research [1]. Cloud computing has benefited the technological scene massively over the past few years. With this massive benefit comes some interesting questions regarding the performance and reliability of cloud computing architectures. By rigorously testing a virtual cloud environment, we will discuss open research challenges regarding the proposed framework. Cloud computing has a vast array of implementations as well as architectures, therefore it is critical to test a common cloud architecture and discover possible drawbacks and solutions for cloud computing environments.

Millions of tons of generated glass are wasted each year and being added to landfills in which glass takes one million years to decompose. Since the wasted glass contains a significant amount of silica, a main component in other supplementary cementitious materials (SCMs), this research focuses on whether waste glass powder can be used to reduce alkali-silica reaction (ASR). The glass powders were created from either a dust collection or by additional crushing, with possible blending of an existing SCM fly ash. In addition, compressive strengths of mortar mixtures with each glass powder or combined with fly ash at varying replacements of cement were also monitored. Other common SCMs were compared to the glass powders and fly ash for ASR mortar performance. The glass dust was more effective at reducing ASR than the crushed glass. With moderately reactive aggregates, all combinations of glass or fly ash at 40 percent replacement of cement were found to be acceptable for ASR resistance. However, all glass powders were also found to reduce strength of the mortar.

Introduction: Since the introduction of Island Grammars, they have been successfully used for a variety of tasks, including impact analysis, multi-lingual parsing, and source code identification. However, there has been no attempt to automate the generation of Island Grammars. Objective: This research considers the development of a method to automate the merging of Island Grammar components. The goal of this is to facilitate the development of an approach to automate the creation of Island Grammars. The result of this is the reduction in initial effort and maintenance effort required for Island Grammar engineering. Methods: We develop an automated approach to merge the components of grammars. To evaluate this approach, we conducted two experiments, each using a factorial design of five replications each. We randomly selected pairs of grammars from each of three size categories to assess the effects of the merging process on the maintenance effort and complexity of the generated grammars. Results: We found that in nearly all cases, the application of this merging approach reduces the maintenance effort and complexity of the grammars. Limitations: The primary limitation of this research is that this approach is currently limited to grammars written in the Antlr4 grammar format. Conclusions: This work presents the initial steps towards the automated construction of Island and Tolerant Grammars. We have shown that this approach to merging grammar components follows suit with the expectations of Island and Tolerant grammars (reduction in maintenance effort and complexity).

One of the biggest challenges in wireless multimedia communications is to provide satisfactory Quality of Experience (QoE) to the users. Recently, numerous QoE maximization metrics and techniques have been proposed to jointly improve the network performance and user satisfaction. However, these methods are built upon postulates of Expected Utility Theorem (EUT). In this paper, we discuss the limitations of EUT in modeling QoE and explore the nuances in Prospect Theory (PT) such as asymmetrical s-shaped value function and reference point dependence to develop a prospect-theoretic QoE maximization framework by incorporating price in QoE model. An algorithm to determine the amount of data that users should purchase at any given cost such that their QoE is maximized, is also presented. As an exemplary scenario, we consider a simplified multimedia communication network with two users, where both users request the same multimedia content and aim to achieve the best possible QoE. Traditional EUT-based price-QoE model has been adopted for the first user, while the proposed PT-based prospect theoretic multimedia pricing QoE model has been used for the second user. Simulation studies conducted with H.265 multimedia codec data reveal that PT user achieved higher QoE in comparison to EUT user at a lower cost. Results also indicated that PT-based modeling can improve system throughput and network revenue.

Critical to the survivability of any organization utilizing large turbine powered aircraft in a commercial setting is the ability to provide reliable service at a competitive cost. In the cost competitive market that such businesses find themselves in today, a very real advantage, both from an economical cost and environmental cost, is to explore ways to reduce the amount of jet fuel used during aircraft operation. While the development of more efficient aircraft has always been a key developmental improvement of aircraft since Orville and Wilbur Wright's flights in 1903, it was not until the Energy Crisis of 1973 that serious research and development of such technologies for large aircraft took on new importance. Critical to these efforts have been technological developments that make aircraft more efficient, either through active or passive systems that reduce an aircraft fuel consumption and also decrease greenhouse gas emissions. Discussion will include efforts to reduce aerodynamic drag, increasing engine fuel burn efficiency, and technologies that change the basic operation of the aircraft with an eye to fuel usage reductions. Several of these improvements are now commonplace among aircraft builders and aircraft operations, while others proved to be either too complex to be fielded by aircraft operators, or not effective enough to justify their development or implementation cost. Developments in the advance of aircraft fuel efficiency have continued since then. With current global efforts to combat climate change, these efforts for fuel efficiency, and thus a reduction in greenhouse gas emissions, have taken on a new importance. As such, current trends and technology developments will also be discussed, as well as an emphasis on future developments.
在商业环境中使用大型涡轮动力飞机的任何组织的生存能力的关键是以具有竞争力的成本提供可靠服务的能力。在成本竞争激烈的市场中，这些企业发现自己在今天，一个非常真正的优势，从经济成本和环境成本，是探索减少飞机运行过程中使用的喷气燃料的数量的方法。虽然自1903年奥维尔和威尔伯·赖特(Orville and Wilbur Wright)的飞行以来，开发更高效的飞机一直是飞机发展的关键改进，但直到1973年的能源危机，大型飞机的此类技术的认真研究和开发才具有新的重要性。这些努力的关键是技术的发展，使飞机更有效率，无论是通过主动或被动系统，减少飞机的燃料消耗，也减少温室气体排放。讨论将包括减少气动阻力的努力，提高发动机燃油燃烧效率，以及改变飞机基本操作的技术，以减少燃料使用。其中一些改进现在在飞机制造商和飞机运营中很常见，而另一些被证明过于复杂而无法由飞机运营商部署，或者不够有效，不足以证明其开发或实施成本是合理的。从那时起，飞机燃油效率的进步一直在继续。随着当前全球应对气候变化的努力，这些提高燃油效率从而减少温室气体排放的努力具有了新的重要性。因此，还将讨论当前的趋势和技术发展，并强调未来的发展。

Intelligent algorithms are constantly being developed to improve the ability of machines to extract and process meaningful data in a variety of situations. In this work, we present a machine learning pipeline that streamlines the task of selecting preprocessing algorithms, feature extraction algorithms, and classification algorithms. We demonstrate the pipeline by identifying volcanoes in synthetic aperture radar (SAR) images of the surface of the planet Venus. This dataset is imbalanced, in the sense that there are relatively few images containing volcanoes, which is a common situation in many autonomous sensing tasks. We show that our machine learning pipeline is able to identify a set of algorithms that can be used together to identify volcanoes with high recall. While the precision of the classifier is poor, it can still be used to reduce the overall size of the dataset and improve the balance of the dataset.

This paper studies combine-then-equalize and equalize-then-combine receiver architectures in a multicarrier scenario motivated by 5G cellular systems. The BER performance of these two receiver architectures with polarization diversity is compared. The results show that the combine-then-equalize approach better exploits the inherent diversity in the system.
