In this work we present three experimental, compact desk-top imaging systems: SXR and EUV full field microscopes and the SXR contact microscope. The systems are based on laser-plasma EUV and SXR sources based on a double stream gas puff target. The EUV and SXR full field microscopes, operating at 13.8 nm and 2.88 nm wavelengths are capable of imaging nanostructures with a sub-50 nm spatial resolution and short (seconds) exposure times. The SXR contact microscope operates in the “water-window” spectral range and produces an imprint of the internal structure of the imaged sample in a thin layer of SXR sensitive photoresist. Applications of such desk-top EUV and SXR microscopes, mostly for biological samples (CT26 fibroblast cells and Keratinocytes) are also presented. Details about the sources, the microscopes as well as the imaging results for various objects will be presented and discussed. The development of such compact imaging systems may be important to the new research related to biological, material science and nanotechnology applications.

Mobile Siaran is an official reporting application intended for the people of the city of Tangerang Selatan (South Tangerang). However, after conducting interviews with stakeholders and respondents, there were several problems with the display of the mobile application. From the results of the interview, it indicates that there are still some applications that need improvement. To fix the problem with the Mobile Siaran application display, the solution given is to improve the user interface design using the Goal Direct Design method. In addition, it also uses the success rate calculation technique and the System Usability Scale (SUS) to measure the usability value. Meanwhile, the User Experience Questionnaire (UEQ) measures the value of user experience. The result of this research is a user interface design made in stages in the Goal Direct Design method, namely research, modeling, requirements, frameworks, and refinement. The final evaluation, the results of the improvement using calculations, the success rate has increased from 93.5% to 99.3%, SUS from an average score of 58.19 which can be said to be quite satisfactory with the letter D value to 81.83 which can be accepted with the value of the letter A, while UEQ shows all aspects that have improved with very good and good criteria which means that improvements to user interface design can solve problems that exist in the application and improve the user experience.

<p>傳統的建築設計課程皆以每學期幾次不同題型的設定,期望在設計操作的反復練習中,幫助操作者探索合適的操作方法並從中建立設計邏輯。設計題目的設定規範了操作的方向與期望的成果,但因設計發展並沒有既定的步驟與方法,常因個人經驗與所選擇設計方式的不同,導致過於感性的思維模式,也造就了理性建築設計教學的挑戰。此研究針對題目設定與設計邏輯的關係,試圖避開操作者可預期的結果,並藉過程中不同階段性的操作設定,試圖建立一種設計邏輯發展的依據。</p> <p>&nbsp;</p><p>Traditionally, architecture design studio requires few exercises per semester for students to practice design method and develop design thinking. As design exercises often direct design approach and also establish expectation of outcome, there is no guaranty procedure or design method to follow in order to achieve the best outcome. Since design development heavily based on experience of operation and choice of approach, sensible thinking process is often involved and sets challenge for rational architectural pedagogy. This research aims to exam the design thinking process of students by setting up specific design exercise to avoid predictable operation process, in order to direct specific design approach according to established guidance for further development. </p> <p>&nbsp;</p>

This paper describes a method for calculating the shape of duct that leads to a prescribed pressure distribution on the duct walls. The proposed design method is computationally inexpensive, robust, and a simple extension of existing computational fluid dynamics methods; it permits the duct shape to be directly calculated by including the coordinates that define the shape of the duct wall as dependent variables in the formulation. This “direct design method” is presented by application to two-dimensional ideal flow in ducts. The same method applies to many problems in thermofluids, including the design of boundary shapes for three-dimensional internal and external viscous flows.
