Abstract:
The expanding scope of chemical reactions applied to nucleic acids has diversified the design of nucleic acid-based technologies that are essential to medicinal chemistry and chemical biology. Among chemical reactions, visible light photochemical reaction is considered a promising tool that can be used for the manipulations of nucleic acids owing to its advantages, such as mild reaction conditions and ease of the reaction process. Of late, inspired by the development of visible light-absorbing molecules and photocatalysts, visible light-driven photochemical reactions have been used to conduct various molecular manipulations, such as the cleavage or ligation of nucleic acids and other molecules as well as the synthesis of functional molecules. In this review, we describe the recent developments (from 2010) in visible light photochemical reactions involving nucleic acids and their applications in the design of nucleic acid-based technologies including DNA photocleaving, DNA photoligation, nucleic acid sensors, the release of functional molecules, and DNA-encoded libraries.

Abstract:
A microcontroller-based control system is a direct outgrowth of the extensive advances in the Integrated Circuit design and microelectronic device processing technology. This has led to the development of new forms of technologies. This paper presents a technique of microcontroller based control system for controlling the lights of a room. Using the technique, according to the intensity of the sunlight in a room, the states of light of that room will change. Therefore we need to collect data or information from the environment using light sensors to control lights. The microcontroller collects the information from the atmosphere and changes the state of different lights. The analog data collected by the sensors are converted to digital form by an Analog to Digital Converter (ADC) and then fed to the microcontroller. The output data stream of the microcontroller is in digital form by which analog device lights will be controlled.

Abstract. RF MEMS based switch matrices have several advantages compared to the mechanical or solid-state switch based ones for space applications. They are compact, light and less lossy with a high linearity up to high frequency. In this work, a 12 × 12 switch matrix with RF MEMS and LTCC technologies is presented based on the planar Beneš network. The simulated performance of the 12 × 12 switch matrix is below −12 dB IL (Insertion Loss) up to C band and −15 dB RL (Return Loss) up to Ku band. Moreover, it has a good isolation better than −50 dB. A 4 × 4 switch matrix with the same design process and technologies is fabricated and measured to verify the 12 × 12 switch matrix design process. The measured performance agrees very well to the simulations.

Abstract:
China intends to close the technological gap from Western countries in microprocessor production by 2021. 46 new projects worth billions of dollars have already been launched in the country. Most of these projects receive direct or indirect state support, which creates a huge demand for domestic semiconductors. By a government decree, all servers in government offices and state-owned enterprises will be preferentially equipped with processors of domestic production. As a result, their sales are expected to grow at a rate of 20% annually. First of all, we are talking about “Loongson”, “Shenwei” and “Phytium” chips (the latter are the development of the Chinese military-industrial complex). The Shenwei processors, which have proved their effectiveness, are promising: they are the ones that run the world's most powerful supercomputer, Sunway Taihu Light, which consists of 10.65 million cores and performs 93 quadrillion operations per second.

Abstract:
With the increase in the use of daylight in architecture, providing visual comfort values as well as physical and psychological effects on people and minimizing the lighting energy need of the building have become important in terms of design. Today, with the development of daylight technologies, economic light tubes have become popular in Architecture. Light tubes have become an effective method in Architecture in terms of energy efficiency to illuminate areas of a building that are exposed to limited sunlight. In addition, people prefer to use daylight by nature. Therefore, the use of light tubes continues to increase in buildings with modern architecture. However, due to architectural design and necessities, daylight is used in a limited way in interior areas. While architects determine the position of the light tubes in the building in order for daylight to reach the dark and dim spots of the buildings, knowing the Illuminance level performance of the positioned light tubes has become a necessity for efficient use. In the study conducted to solve this problem, the Daylight Factor Method specified in the European Union EN 17037:2018 Standard was used in the use of light tubes. As stated in the relevant standard, the methods in the daylight factor value ISO 15469:2004 were used. The evaluation of the buildings in terms of daylight performance was calculated in the simulation environment according to the horizontal luminance of the daylight openings. With the designed simulation, the values in the conditions specified in the criteria related to the light tubes are provided. In this way, a light tube that provides energy efficiency is compatible with the circadian rhythm and is compatible with the architecture of this building, and optimum illuminance level values have been determined for the warehouse, which is the subject of the study in the simulation environment.

Abstract:
Most of the present time outdoor lighting investments seem to be focused on road and automotive traffic facilities or oriented toward safety, security and efficiency.  We can identify this in many of the world cities, as a globally spread common practice, where lighting is still highly perceived as a pure matter of quantities’ distribution.  Considering the tendency for the Human being to become an Urban-being, the future of human quality of life will, most probably, depend on the fortune of so called sustainable cities.  By lighting design, and promoting the return of the city lights to the Human scale, is argued that the Urban Planning approach may not correspond best to the person viewpoint, due to scale.  Will be explored, this way, by positioning the perspective at human eye level and not zenith bird-view, the traditional perspective over the city, where from not a soul ever experiences urbanity.  The method definition will be based mostly on observations and analysis of the Light and Lighting transitions taking place in cities, experienced by its inhabitants, from daytime to night time.

Abstract:
What transportation means corporations choose for satisfying their mobility needs may have an essential impact on the environment. Choosing environmental friendly, alternatives such as battery driven light electric vehicles, would mean drastically contributing to a more sustainable environment. Meanwhile as carsharing solutions, continuously rise in popularity together with other sharing economy business models so do their possibilities to satisfy the mobility needs for corporations either by them implementing their own carsharing service or by investing on external services offered by established carsharing operators. This thesis has investigated and designed for a Zbee based corporate carsharing service, to be used between the affiliates of Vinngroup in Gothenburg. A Zbee is a light electric three-wheeled vehicle. Based on user-centred service design methods, methods suggested for sharing economy solutions, as well as user experience design methods, this thesis identified that users have different individualistic needs in a workplace and prior experiences that affects how they will use the service.In order to satisfy these different needs, it was found, the system needs to provide real-time vehicle and scheduling information for ensuring the users vehicle availability and service reliability, being one of the first requirement from the users. Further the service should provide users with functions that help users through the different use phases that were identified during this work. The findings found were then presented visually by designing mobile application prototypes and testing them on participants iteratively. The final set of prototypes was further evaluated by using the System Usability Scale, an effective and popular tool for measuring the usability of products and services. This evaluation gave the scores 77.5, 92.5, 90, 87.5 and 72.5, thus this giving a mean-value of 84 and a median of 87.5. All these scores suggests the prototype has high usability.

Abstract:
For the last four decades, the semiconductor industry has experienced an exponential growth. According to the ITRS, as we advance into the era of nanotechnology, the traditional CMOS electronics is reaching its physical and economical limits. The main objective of this thesis is to explore novel design opportunities for reconfigurable architectures given by the emerging technologies. On the one hand, the thesis will focus on the traditional FPGA architecture scheme, and survey some structural improvements brought by disruptive technologies. While the memories and routing structures occupy the major part of the FPGAs total area and mainly limit the performances, 3-D integration appears as a good candidate to embed all this circuitry into the metal layers. Configuration and routing circuits based on back-end compatible resistive memories, a monolithic 3-D process flow and a prospective vertical FETs process flow are introduced and assessed within a complete architectural context. On the other hand, the thesis will present some novel architectural schemes for ultra-fine grain computing. The size of the logic elements can be reduced thanks to inherent properties of the technologies, such as the crossbar organization or the controllable polarity of carbon electronics. Considering the granularity of the logic elements, specific fixed and incomplete interconnection topologies are required to prevent the large overhead of a configurable interconnection pattern. To evaluate the potentiality of this new architectural scheme, a specific benchmarking flow will be presented in order to explore the ultra-fine grain architectural design space.

Abstract:
The conceptual design phase of an aerospace system development program is typically characterized by short duration and relatively limited resources, yet design decisions are made that have critical implications on program risk. To address the more aggressive requirements, one of these decisions is the selection of advanced technologies. System developers need to assess advanced technologies early on, but are faced with uncertainties surrounding the potential net benefits. The concept introduced in this study is uncertainty characterization as a way to better understand the associated risk. A framework was developed to guide the interaction between the technology developer and the system developer. The objective is to gain a more comprehensive landscape of the technology options by explicitly considering the effects of uncertainty in the decision making process. This can ultimately facilitate prioritization and resource management during conceptual design. An example case of advanced wing technology was applied to the design of a high-altitude long-endurance unmanned aerial vehicle to demonstrate the implementation of the framework.

Abstract:
People with the autoimmune disease multiple sclerosis (MS) have few options for educational activities. Although web-based instruction may be a viable option, little is known about how people with MS perceive this form of learning. The purpose of this qualitative study was to understand the experiences of people with MS regarding web- based instruction. The 3 learning structures--differentiated instruction, collaborative learning, and assistive technology--provided the conceptual framework for this research. Nine volunteers from the Pacific Northwest area of the United States who have MS were individually interviewed for this basic qualitative study. Transcripts were analyzed using open, axial, and selective coding. The results indicated that all participants found personal and professional benefits of their experience with web-based instruction and used course management systems to successfully communicate with instructors or peers. Participants also noted that these management systems did not directly aggravate their MS disease symptoms. Findings from the study may be useful information to individuals with MS for effectively managing their educational choices. This study's results could also be used by learning institutions to improve the access to education and allow individuals with MS to more fully participate in training opportunities.

Abstract:
Technological innovations in sanitation are poised to address the great need for sanitation improvements in low-income countries. Worldwide, more than 2.4 billion people lack access to improved sanitation facilities. Innovative waste treatment and sanitation technologies aim to incorporate user-centered findings into technology engineering and design. Without a focus on users, even the most innovative technology solutions can encounter significant barriers to adoption. Drawing on a household survey conducted in urban slum communities of Ahmedabad, India, this research brief identifies toilet and sanitation preferences, amenities, and attributes that might promote adoption of improved sanitation technologies among potential user populations. This work uses supplemental insights gained from focus groups and findings from the literature. Based on our research, we offer specific guidance for engineering and design of sanitation products and technologies.

Taiber, Joachim. Unsettled Topics Concerning the Impact of Quantum Technologies on Automotive Cybersecurity. SAE International, December 2020. http://dx.doi.org/10.4271/epr2020026.

Full text
Abstract:
Quantum computing is considered the “next big thing” when it comes to solving computational problems impossible to tackle using conventional computers. However, a major concern is that quantum computers could be used to crack current cryptographic schemes designed to withstand traditional cyberattacks. This threat also impacts future automated vehicles as they become embedded in a vehicle-to-everything (V2X) ecosystem. In this scenario, encrypted data is transmitted between a complex network of cloud-based data servers, vehicle-based data servers, and vehicle sensors and controllers. While the vehicle hardware ages, the software enabling V2X interactions will be updated multiple times. It is essential to make the V2X ecosystem quantum-safe through use of “post-quantum cryptography” as well other applicable quantum technologies. This SAE EDGE™ Research Report considers the following three areas to be unsettled questions in the V2X ecosystem: How soon will quantum computing pose a threat to connected and automated vehicle technologies? What steps and measures are needed to make a V2X ecosystem “quantum-safe?” What standardization is needed to ensure that quantum technologies do not pose an unacceptable risk from an automotive cybersecurity perspective?

Cook, Stephen, and Loyd Hook. Developmental Pillars of Increased Autonomy for Aircraft Systems. ASTM International, January 2020. http://dx.doi.org/10.1520/tr2-eb.

Full text
Abstract:
Increased automation for aircraft systems holds the promise to increase safety, precision, and availability for manned and unmanned aircraft. Specifically, established aviation segments, such as general aviation and light sport, could utilize increased automation to make significant progress towards solving safety and piloting difficulties that have plagued them for some time. Further, many emerging market segments, such as urban air mobility and small unmanned (e.g., small parcel delivery with drones) have a strong financial incentive to develop increased automation to relieve the pilot workload, and/or replace in-the-loop pilots for most situations. Before these advances can safely be made, automation technology must be shown to be reliable, available, accurate, and correct within acceptable limits based on the level of risk these functions may create. However since inclusion of these types of systems is largely unprecedented at this level of aviation, what constitutes these required traits (and at what level they must be proven to) requires development as well. Progress in this domain will likely be captured and disseminated in the form of best practices and technical standards created with collaboration from regulatory and industry groups. This work intends to inform those standards producers, along with the system designers, with the goal of facilitating growth in aviation systems toward safe, methodical, and robust inclusion of these new technologies. Produced by members of the manned and unmanned small aircraft community, represented by ASTM task group AC 377, this work strives to suggest and describe certain fundamental principles, or “pillars”, of complex aviation systems development, which are applicable to the design and architectural development of increased automation for aviation systems.

Becker, Peter J. Using the Light Weight Deflectometer for Performance-Based Quality Assurance Testing of Cement Modified Subgrades. Purdue University, 2021. http://dx.doi.org/10.5703/1288284317304.

Full text
Abstract:
This report documents the findings from SPR-4230 (Alternative Quality Assurance Methods for Compacted Subgrade). The main objective of SPR-4230 involved establishing performance-related quality assurance (QA) test methods for pavement subgrade construction. Because INDOT generally prefers specifying subgrade treatment type IBC (i.e., 14-in. cement modified subgrade), this study focused on performance-based QA test methods for constructing cement modified subgrade. Moreover, INDOT prefers using light weight deflectometer (LWD) for chemically modified subgrade construction acceptance, so this study aimed to use LWD deflection measurements as performance-related construction acceptance criteria. A laboratory study was performed to relate LWD deflections with resilient modulus that is the key subgrade performance-related parameter in pavement design. In addition, LWD deflections were related with unconfined compressive strength increase that is the key parameter in chemical soil modification mix design. A rigorous field study consisting of LWD testing and falling weight deflectometer (FWD) testing at INDOT new pavement construction sites was conducted to verify the laboratory developed relationship. Recommendations for implementing results of this study into cement modified subgrade construction acceptance is provided, as are recommendations for future research.

Automated-Entry Patient-Generated Health Data for Chronic Conditions: The Evidence on Health Outcomes. Agency for Healthcare Research and Quality (AHRQ), March 2021. http://dx.doi.org/10.23970/ahrqepctb38.

Abstract:
Background. Automated-entry consumer devices that collect and transmit patient-generated health data (PGHD) are being evaluated as potential tools to aid in the management of chronic diseases. The need exists to evaluate the evidence regarding consumer PGHD technologies, particularly for devices that have not gone through Food and Drug Administration evaluation. Purpose. To summarize the research related to automated-entry consumer health technologies that provide PGHD for the prevention or management of 11 chronic diseases. Methods. The project scope was determined through discussions with Key Informants. We searched MEDLINE and EMBASE (via EMBASE.com), In-Process MEDLINE and PubMed unique content (via PubMed.gov), and the Cochrane Database of Systematic Reviews for systematic reviews or controlled trials. We also searched ClinicalTrials.gov for ongoing studies. We assessed risk of bias and extracted data on health outcomes, surrogate outcomes, usability, sustainability, cost-effectiveness outcomes (quantifying the tradeoffs between health effects and cost), process outcomes, and other characteristics related to PGHD technologies. For isolated effects on health outcomes, we classified the results in one of four categories: (1) likely no effect, (2) unclear, (3) possible positive effect, or (4) likely positive effect. When we categorized the data as “unclear” based solely on health outcomes, we then examined and classified surrogate outcomes for that particular clinical condition. Findings. We identified 114 unique studies that met inclusion criteria. The largest number of studies addressed patients with hypertension (51 studies) and obesity (43 studies). Eighty-four trials used a single PGHD device, 23 used 2 PGHD devices, and the other 7 used 3 or more PGHD devices. Pedometers, blood pressure (BP) monitors, and scales were commonly used in the same studies. Overall, we found a “possible positive effect” of PGHD interventions on health outcomes for coronary artery disease, heart failure, and asthma. For obesity, we rated the health outcomes as unclear, and the surrogate outcomes (body mass index/weight) as likely no effect. For hypertension, we rated the health outcomes as unclear, and the surrogate outcomes (systolic BP/diastolic BP) as possible positive effect. For cardiac arrhythmias or conduction abnormalities we rated the health outcomes as unclear and the surrogate outcome (time to arrhythmia detection) as likely positive effect. The findings were “unclear” regarding PGHD interventions for diabetes prevention, sleep apnea, stroke, Parkinson’s disease, and chronic obstructive pulmonary disease. Most studies did not report harms related to PGHD interventions; the relatively few harms reported were minor and transient, with event rates usually comparable to harms in the control groups. Few studies reported cost-effectiveness analyses, and only for PGHD interventions for hypertension, coronary artery disease, and chronic obstructive pulmonary disease; the findings were variable across different chronic conditions and devices. Patient adherence to PGHD interventions was highly variable across studies, but patient acceptance/satisfaction and usability was generally fair to good. However, device engineers independently evaluated consumer wearable and handheld BP monitors and considered the user experience to be poor, while their assessment of smartphone-based electrocardiogram monitors found the user experience to be good. Student volunteers involved in device usability testing of the Weight Watchers Online app found it well-designed and relatively easy to use. Implications. Multiple randomized controlled trials (RCTs) have evaluated some PGHD technologies (e.g., pedometers, scales, BP monitors), particularly for obesity and hypertension, but health outcomes were generally underreported. We found evidence suggesting a possible positive effect of PGHD interventions on health outcomes for four chronic conditions. Lack of reporting of health outcomes and insufficient statistical power to assess these outcomes were the main reasons for “unclear” ratings. The majority of studies on PGHD technologies still focus on non-health-related outcomes. Future RCTs should focus on measurement of health outcomes. Furthermore, future RCTs should be designed to isolate the effect of the PGHD intervention from other components in a multicomponent intervention.
