<p>The problems generally faced by farmers are that vegetables easily rotting due to delayed selling time and higher hygienic standard of vegetables. Based on an interview, we acknowledge that the farmers are unable to understand the utilization of ultraviolet irradiation technology. UV irradiation facilities - which help kills various types of bacteria, spores, protozoan viruses and algae - should be placed near vegetable harvest location. The physical part of vegetables requires special attention and they should not be moved on a regular basis to prevent damages. However, the harvest location is quite distant from electricity sources. As a solution to overcome this problem, a solar powered UV irrayer facility equipped with a portable bag is required. Besides that, the tool should be fitted with branded plastic casings to hold the vegetable to improve selling value, safety, and readiness of the vegetables. The objective of the utilization of this appropriate technology is to improve the quality of the harvested crops. Vegetables will be free from bacteria and risks of Covid-19 exposures. The target of this program is to improve vegetable selling sales rate and to improve the prosperity of the farmers better, or at least as high as pre-pandemic era. The method used to procure this appropriate technology is a design thinking method that covers empathy, define, ideate, prototype, and testing. The implementation of the counseling and training activities were conducted on-line and off-line whilst also applying a strict health protocol. The activity was conducted for 4 months.</p>

Purpose: The COVID-19 crisis had a severe impact on University education (on-line learning, off-campus examinations). In addition, the COVID-19 pandemic raises questions about the quality of education and training in a number of disciplines, like fashion design, where social entrepreneurship opportunities and in-situ functionalities are essential for a quality curriculum. Hence, to remain relevant and innovative, fashion design thinking will need to reimagine education in order to create skills for e-entrepreneurship and prepare fashion entrepreneurs for e-business. Therefore, new concepts for fashion design thinking for innovation and e-entrepreneurship have to introduce in an e-classrooms curriculum. Methodology: This study employed the use of questionnaires to collect quantitative data and structured interviews to compile qualitative data (opinions) of two main groups of fashion design professionals: (a) clothing merchants and manufacturers, (b) fashion design green entrepreneurs. In particular, linear regression used to analyze the quantitative data (SPSS functionality) and data analytics software (QSR NVivo) adopted to encode the answers from the interviews. Findings: Findings obtained in this study show that &ndash;with the admission of agile entrepreneurship superiority and functional solution in crises like COVID-19- the green entrepreneurs are better positioning are better prepared to withstand the current COVID-19 or future crisis. Hence the requirement to integrate green entrepreneurship courses into the fashion d esign curriculum will be proposed to create innovation and value in fashion design thinking. Originality and value: This study inserts itself in a multidisciplinary field, mainly composed of four disciplinary areas: &ldquo;fashion design thinking and education&rdquo;, &ldquo;digital transformation&rdquo;, &rdquo;green entrepreneurship&rdquo;, and &ldquo;work-from-home entrepreneurship&rdquo;. The introduction of the new term &ldquo;Agile entrepreneurship&rdquo; as a new disciplinary concept in fashion design curriculum is also crucial.&nbsp; Research limitations: The main limitation of this study is related to the definition of &ldquo;Agile entrepreneurship&rdquo; itself in COVID-19 and beyond work-from-home era, as bibliography still diverges on this subject.

The Fourier Transform

In the past few years on-line digital television frame store devices coupled to computers have been employed to attempt to measure the microscope parameters of defocus and astigmatism. The ultimate goal of such tasks is to fully adjust the operating parameters of the microscope and obtain an optimum image for viewing in terms of its information content. The initial approach to this problem, for high resolution TEM imaging, was to obtain the power spectrum from the Fourier transform of an image, find the contrast transfer function oscillation maxima, and subsequently correct the image. This technique requires a fast computer, a direct memory access device and even an array processor to accomplish these tasks on limited size arrays in a few seconds per image. It is not clear that the power spectrum could be used for more than defocus correction since the correction of astigmatism is a formidable problem of pattern recognition.

Minimum Distances

A Scanning Transmission Electron Microscope (STEM) was coupled to a small computer. The system (see Fig. 1) has been built using a Philips EM400, equipped with a scanning attachment and a DEC PDP11/34 computer with 34K memory. The gun (Fig. 2) consists of a continuously renewed tip of radius 0.2 to 0.4 μm of a tungsten wire heated just below its melting point by a focussed laser beam (1). On-line operation procedures were developped aiming at the reduction of the amount of radiation of the specimen area of interest, while selecting the various imaging parameters and upon registration of the information content. Whereas the theoretical limiting spot size is 0.75 nm (2), routine resolution checks showed minimum distances in the order 1.2 to 1.5 nm between corresponding intensity maxima in successive scans. This value is sufficient for structural studies of regular biological material to test the performance of STEM over high resolution CTEM.

Projection Angle

Three-dimensional (3D) microstructure visualization on the electron microscope requires that the sample be tilted to different positions to collect a series of projections. This tilting should be performed rapidly for on-line stereo viewing and precisely for off-line tomographic reconstruction. Usually a projection series is collected using mechanical stage tilt alone. The stereo pairs must be viewed off-line and the 60 to 120 tomographic projections must be aligned with fiduciary markers or digital correlation methods. The delay in viewing stereo pairs and the alignment problems in tomographic reconstruction could be eliminated or improved by tilting the beam if such tilt could be accomplished without image translation.A microscope capable of beam tilt with simultaneous image shift to eliminate tilt-induced translation has been investigated for 3D imaging of thick (1 μm) biologic specimens. By tilting the beam above and through the specimen and bringing it back below the specimen, a brightfield image with a projection angle corresponding to the beam tilt angle can be recorded (Fig. 1a).

In recent developments, the ASU HB5 has been modified so that the timing, positioning, and scanning of the finely focused electron probe can be entirely controlled by a host computer. This made the asynchronized handshake possible between the HB5 STEM and the image processing system which consists of host computer (PDP 11/34), DeAnza image processor (IP 5000) which is interfaced with a low-light level TV camera, array processor (AP 400) and various peripheral devices. This greatly facilitates the pattern recognition technique initiated by Monosmith and Cowley. Software called NANHB5 is under development which, instead of employing a set of photo-diodes to detect strong spots on a TV screen, uses various software techniques including on-line fast Fourier transform (FFT) to recognize patterns of greater complexity, taking advantage of the sophistication of our image processing system and the flexibility of computer software.

Convergent Beam

A method has been developed that allows on-line measurement of the thickness of crystalline materials in the analytical electron microscope. Two-beam convergent beam electron diffraction (CBED) patterns are digitized from a JEOL 2000FX electron microscope into an Apple Macintosh II microcomputer via a Gatan #673 CCD Video Camera and an Imaging Systems Technology Video 1000 frame-capture board. It is necessary to know the lattice parameters of the sample since measurements are made of the spacing of the diffraction discs in order to calibrate the pattern. The sample thickness is calculated from measurements of the spacings of the fringes that are seen in the diffraction discs. This technique was pioneered by Kelly et al, who used the two-beam dynamic theory of MacGillavry relate the deviation parameter (Si) of the ith fringe from the exact Bragg condition to the specimen thickness (t) with the equation:Where ξg, is the extinction distance for that reflection and ni is an integer.

Electron Microscopes

Remote on-line electron microscopy is rapidly becoming more available as improvements continue to be developed in the software and hardware of interfaces and networks. Scanning electron microscopes have been driven remotely across both wide and local area networks. Initial implementations with transmission electron microscopes have targeted unique facilities like an advanced analytical electron microscope, a biological 3-D IVEM and a HVEM capable of in situ materials science applications. As implementations of on-line transmission electron microscopy become more widespread, it is essential that suitable standards be developed and followed. Two such standards have been proposed for a high-level protocol language for on-line access, and we have proposed a rational graphical user interface. The user interface we present here is based on experience gained with a full-function materials science application providing users of the National Center for Electron Microscopy with remote on-line access to a 1.5MeV Kratos EM-1500 in situ high-voltage transmission electron microscope via existing wide area networks. We have developed and implemented, and are continuing to refine, a set of tools, protocols, and interfaces to run the Kratos EM-1500 on-line for collaborative research. Computer tools for capturing and manipulating real-time video signals are integrated into a standardized user interface that may be used for remote access to any transmission electron microscope equipped with a suitable control computer.
