And Performance

Significant progress has been made recently in solar parabolic trough technology development and deployment. Part of this success is due to the changing world energy scenario and the recognition that viable renewable energy technologies can play a role in supplying world energy needs. Part is also due to ongoing collaborative efforts by industry and the Department of Energy’s (DOE) Concentrating Solar Power Program (CSP) to enhance the state of the technology in terms of both cost and performance. Currently, there are two trough concentrator projects which the DOE CSP program is supporting. One company, Solargenix, is developing a design to be used in a 64MW plant outside of Boulder City, Nevada. This design is based on the original LUZ LS-2 trough concentrators employed at the Solar Electric Generating Systems (SEGS) plants in Southern California. Another company, Industrial Solar Technology (IST), is working on a scale-up of their design used historically for process heat applications. Very different from the LS-2 approach, this design is still in the research and development stages. One way in which the DOE CSP parabolic trough program assists industry is by providing optical testing and qualification of their concentrator designs. This paper describes the Video Scanning Hartmann Optical Test System (VSHOT) used to optically test both of these designs. The paper also presents the results of tests performed in the past year and what impact the testing has had on the developmental direction of each design.

This article shares processes of engagement with practice-as-research in place-based performance and creative technology, specifically mobile augmented reality (AR). It addresses the application of methodologies from an AR performance, Uninvited Guests and Duncan Speakman’s Billennium (2018), in Future Places Toolkit (Clarke et al., 2020), an engagement activity for neighbourhood visioning and planning consultation. It outlines the steps taken to evolve Billennium beyond an artwork into a tool for use in citizen-led design, and to transfer practice-as-research in performance and technology to a professional architecture and community context, specifically Knowle West in Bristol, UK. By detailing the stages of this research and development process, key learnings will be shared with other researchers seeking to apply their practices to social and civic challenges, and to do so through working in partnership with creative industries and community-based organizations. Future Places Toolkit will be used as a case study to demonstrate the potential of applying approaches from practice-as-research to real-world problems and developing arts practices into products or services. Documenting and reflecting on the process of prototyping the AR toolkit disseminates procedures for commercializing creative research and leads to a critique of the drive to scale up. Future Places Toolkit is considered as a framework for co-creation with communities and interprofessional partners, and methods for responsible innovation are shared. While these are drawn from responsible technology development, they are transferrable to other professional fields and academic engagement, or to commercialization in different disciplines.

Formation to build character in the digital era in the world of education through the development of ethical values and performance support to form the foundation of individual characters expected. Developments in the digital era influence individual lifestyles and patterns of relationships so as to form a new paradigm for helping human needs in carrying out the duties and expectations. The purpose of building character besides having benefits also have a negative impact can be described in the attitudes and behavior of individuals, which occurs demoralisasasi. The method used in building individual character that balance the mind / creativity, feeling / sense of, and willingness / intention in executing their daily duties. The result is an imbalance in the event over them in carrying out daily activities using irrational thoughts, dishonest, irresponsible, did not have a good work ethic. How to cope with the character education should play an active role in shaping the students to have a good character, capable of being honest, responsible, disciplined, passionate, creative and communication skills to achieve success both socially and career aligned with technology development is very fast and sophisticated. The characters develop their conclusion to follow up the results of studies showing that the majority of a person in carrying out daily activities always use excessive feelings so that there is an imbalance between thought, feeling and will

Energy Law

Technological and legal innovation have been central to energy development for centuries. Today’s era of accelerating change is transforming energy law. Disruption and change to established energy sources, supply, distribution, and energy consumer access is driven by legal innovations that, in turn, prompt or respond to technology. Interaction between legal and technological innovation is advancing the growing global effort to transition from high-carbon energy to low-energy or no-carbon energy—evidenced by the 2015 Paris Agreement on climate change and the growing market demand for carbon-free electricity. This global transition to low-emission energy sources allows nations to take advantage of emerging economic opportunities and facilitates new forms of energy technology development, energy distribution, and governance. But progress is uneven and concerns such as energy security are initiating technological innovation in many existing energy technologies. These authors from twenty-one nations examine relevant developments in global energy law triggered by these innovations.

At present, the college English testing system has become an indispensable system in many universities. However, the English test system is not highly humanized due to problems such as unreasonable framework structure. This paper combines data mining technology to build a college English test framework. The college English test system software based on data mining mainly realizes the computer program to automatically generate test papers, set the test time to automatically judge the test takers’ test results, and give out results on the spot. The test takers log in to complete the test through the test system software. The examination system software solves the functions of printing test papers, arranging invigilation classrooms, invigilating teachers, invigilating process, collecting test papers, scoring and analyzing test papers in traditional examinations. Finally, this paper analyzes the performance of this paper through experimental research. The research results show that the system constructed in this paper has certain practical effects.

The quality control of drug products during manufacturing processes is important, particularly the presence of different polymorphic forms in active pharmaceutical ingredients (APIs) during production, which could affect the performance of the formulated products. The objective of this study was to investigate the phase transformation of fexofenadine hydrochloride (FXD) and its influence on the quality and performance of the drug. Water addition was key controlling factor for the polymorphic conversion from Form I to Form II (hydrate) during the wet granulation process of FXD. Water-induced phase transformation of FXD was studied and quantified with XRD and thermal analysis. When FXD was mixed with water, it rapidly converted to Form II, while the conversion is retarded when FXD is formulated with excipients. In addition, the conversion was totally inhibited when the water content was <15% w/w. The relationship between phase transformation and water content was studied at the small scale, and it was also applicable for the scale-up during wet granulation. The effect of phase transition on the FXD tablet performance was investigated by evaluating granule characterization and dissolution behavior. It was shown that, during the transition, the dissolved FXD acted as a binder to improve the properties of granules, such as density and flowability. However, if the water was over added, it can lead to the incomplete release of the FXD during dissolution. In order to balance the quality attributes and the dissolution of granules, the phase transition of FXD and the water amount added should be controlled during wet granulation.
