A Model of Architectural Design Education Based on Collaborative and Interactive Thoughts

Background and Objective:The large gap between academic lessons in architecture schools and the labor market in society has made many graduates of architecture schools unfamiliar with the work process and solving architectural issues in society. An important constituent which has been present in Iranian education and training culture from yesteryear, which can be seen in novel education stands around the world, is collaborative education. In this method, learners get accustomed to concerns related to collective benefits and group problem solving. Thus, after graduation students gain higher ability to identify issues in society and solve problems with colleagues and interact with others. The aim of this study is to present a model for collaborative architectural design education, on the subject of decreasing the gap between academic education and work. Some of the benefits which can be gained from this method include preparing learners for work and social life, improving awareness of the educational issue by grouping students of different levels, strengthening students’ responsibility and commitment towards their surrounding environment, objectivism in education, academic education based on the realities of society. Methods: In this study, the method is qualitative and post positivism. It is inductive and first-degree data was collected, organized, and classified. It sought to discover issues surrounding architectural design education in a collaborative manner. Findings:The presented model consequently showed that it is not only synergistic, but also instigates efficiency in design education students. It can also significantly reduce the gap between academic education and the labor market. Conclusion: The results of theoretical and field studies on the proposed model show that architectural design in a participatory and interactive manner while synergizing in education leads to the effectiveness of design education among students. Because in this model, the distance between academic education and students' daily life is reduced. At the same time, students achieve group benefits by raising a sense of solidarity. In this model, students feel responsible for their surroundings and gain more knowledge about the artificial environment around them. Therefore, by identifying the architectural problems of their surroundings, they seek to solve the problem as a group. Students in the architectural design studio, while communicating and creating a dialogue space, will not only be effective in enhancing each other's design capabilities, but will also seek to solve the problem by explaining clear goals and defining the architectural problems around them, by identifying a common goal. Therefore, teaching participatory architecture design reduces the gap between education and society, improves the efficiency of academic education in architectural design, and prepares the learner for professional and social life. It strengthens the student's sense of responsibility and commitment to their environment. It causes objectivism in education and makes it possible to start education by describing the issues of daily life and achieving an accurate understanding of the realities of society. It also enhances learning capabilities through social relationships, organizing experience, innovation, and creativity through pluralism. In the method of teaching participatory architecture design, it is possible to transfer experiences between different levels of students. In this way, based on this model of architectural design education, one of the most important shortcomings of architectural education, which is the long distance between the labor market and the university, will be eliminated.   ===================================================================================== COPYRIGHTS  ©2019 The author(s).

Compact quad-element high-isolation wideband mimo antenna for mm-wave applications

This paper presents a multiple-input multiple-output (MIMO) antenna system for millimeter-wave 5G wireless communication services. The proposed MIMO configuration is composed of four antenna elements, where each antenna possesses an HP-shaped configuration that features simple configuration and excellent performance. The proposed MIMO design can operate at a very wideband of 36.83-40.0 GHz (measured). Furthermore, the proposed MIMO antenna attains a peak gain of 6.5 dB with a maximum element-isolation of -45 dB. Apart from this, the MIMO performance metrics such as envelope correlation coefficient (ECC), diversity gain, and channel capacity (CCL) are analyzed, which demonstrate good characteristics across the operating band. The proposed antenna radiates efficiently with a radiation efficiency of above 80% at the desired frequency band which makes it a potential contender for the upcoming communication applications. The proposed design simulations were performed in the computer simulation technology (CST) software, and measured results reveal good agreement with the simulated one

Printed closely spaced antennas loaded by linear stubs in a mimo style for portable wireless electronic devices

An easy-to-manufacture and efficient four-port-printed Multiple Input Multiple Output (MIMO) antenna operating across an ultra-wideband (UWB) region (2.9-13.6 GHz) is proposed and investigated here. The phenomenon of the polarization diversity is used to improve the isolation between MIMO antenna elements by deploying four orthogonal antenna elements. The proposed printed antenna (40 x 40 x 1.524 mm(3)) is made compact by optimizing the circular-shaped radiating components via vertical stubs on top of the initial design to maximally reduce unwanted interaction while placing them together in proximity. The measurements of the prototype MIMO antennas corroborate the simulation performance. The findings are compared to the recent relevant works presented in the literature to show that the proposed antenna is suitable for UWB MIMO applications. The proposed printed UWB MIMO antenna could be a good fit for compact portable wireless electronic devices

Mimo antenna system for modern 5g handheld devices with healthcare and high rate delivery

In this work, a new prototype of the eight-element MIMO antenna system for 5G communications, internet of things, and networks has been proposed. This system is based on an H-shaped monopole antenna system that offers 200 MHz bandwidth ranges between 3.4-3.6 GHz, and the isolation between any two elements is well below -12 dB without using any decoupling structure. The proposed system is designed on a commercially available 0.8 mm-thick FR4 substrate. One side of the chassis is used to place the radiating elements, while the copper from the other side is being removed to avoid short-circuiting with other components and devices. This also enables space for other systems, sub-systems, and components. A prototype is fabricated and excellent agreement is observed between the experimental and the computed results. It was found that ECC is 0.2 for any two radiating elements which is consistent with the desirable standards, and channel capacity is 38 bps/Hz which is 2.9 times higher than 4 x 4 MIMO configuration. In addition, single hand mode and dual hand mode analysis are conducted to understand the operation of the system under such operations and to identify losses and/or changes in the key performance parameters. Based on the results, the proposed antenna system will find its applications in modern 5G handheld devices and internet of things with healthcare and high rate delivery. Besides that, its design simplicity will make it applicable for mass production to be used in industrial demands

Systematic review of virtual speech therapists for speech disorders

In this paper, a systematic review of relevant published studies on computer-based speech therapy systems or virtual speech therapists (VSTs) for people with speech disorders is presented. We structured this work based on the PRISMA framework. The advancements in speech technology and the increased number of successful real-world projects in this area point to a thriving market for VSTs in the near future; however, there is no standard roadmap to pinpoint how these systems should be designed, implemented, customized, and evaluated with respect to the various speech disorders. The focus of this systematic review is on articulation and phonological impairments. This systematic review addresses three research questions: what types of articulation and phonological disorders do VSTs address, how effective are virtual speech therapists, and what technological elements have been utilized in VST projects. The reviewed papers were sourced from comprehensive digital libraries, and were published in English between 2004 and 2014. All the selected studies involve computer-based intervention in the form of a VST regarding articulation or phonological impairments, followed by qualitative and/or quantitative assessments. To generate this review, we encountered several challenges. Studies were heterogeneous in terms of disorders, type and frequency of therapy, sample size, level of functionality, etc. Thus, overall conclusions were difficult to draw. Commonly, publications with rigorous study designs did not describe the technical elements used in their VST, and publications that did describe technical elements had poor study designs. Despite this heterogeneity, the selected studies reported the effectiveness of computers as a more engaging type of intervention with more tools to enrich the intervention programs, particularly when it comes to children; however, it was emphasized that virtual therapists should not drive the intervention but must be used as a medium to deliver the intervention planned by speech-language pathologists. Based on the reviewed papers, VSTs are significantly effective in training people with a variety of speech disorders; however, it cannot be claimed that a consensus exists in the superiority of VSTs over speech-language pathologists regarding rehabilitation outcomes. Our review shows that hearing-impaired cases were the most frequently addressed disorder in the reviewed studies. Automatic speech recognition, speech corpus, and speech synthesizers were the most popular technologies used in the VSTs
