DESAIN ALAT MONITORING BEBAN GARDU DISTRIBUSI SECARA REAL TIME MENGGUNAKAN METODE PERANCANGAN PRODUK DI PT . PLN (Persero) RAYON BAGUALA

Penelitian ini membahas desain alat monitoring beban gardu distribusi. Alat ini dibuat bekerja secara real time untuk mengurangi potensi kesalahan, serta dapat memonitoring beban gardu setiap jam yang sebelumnya dilakukan oleh manusia yang hanya memonitoring beban gardu tiga bulan sekali. Dalam penelitian ini agar alat dapat bekerja secara real time meliputi, pengukuran arus dan tegangan menggunakan sensor, memilih sistem akuisisi data sebagai jembatan untuk menghubungkan mengirimkan hasil pengukuran ke komputer dan membuat program untuk menampilkan hasil pengukuran pada komputer. Untuk mengukur arus dan tegangan menggunakan sensor ACS712 dan sensor tegangan ZMPT101B. Sistem akuisisi data yang digunakan adalah Arduino Mega 2560, kemudian untuk menampilkan hasil pengukuran pada komputer yang dilakukan oleh sensor arus dan tegangan adalah menggunakan program Graphical User Interfacing (GUI) MATLAB. Pada GUI MATLAB dibuat untuk menampilkan beberapa variabel yang menjadi indikator kondisi gardu yang dimulai dari tegangan gardu, arus gardu, beban gardu hingga persentase beban gardu yang dicuplik setiap satu jam. Uji kinerja alat telah dilakukan untuk memonitoring beban pada gardu BGLWHR2008 yang terletak di Rayon Baguala antara pukul 17:00 hingga pukul 23:00. Proses monitoring dibagi berdasarkan waktu yaitu sebelum jam pemakaian puncak yaitu pukul 17:00 – 19:00, pemakaian beban pucak antara pukul 19:00 – 21:00 dan setelah waktu puncak antara pukul 21:00 – 23:00. Dari hasil monitoring dapat dilihat antar pukul 19:00 – 21:00 pemakaian beban gardu mencapai 55,90 % lebih tinggi 5 % sebelum sebelum waktu jam puncak. Alat ini telah mampu memantau beban gardu dimana hasilnya hampir sama dengan pengukuran yang dilakukan oleh manusia.

Towards an HCI-Based Symbiotic Environment for Alzheimer's Support

Alzheimer's Disease (AD), being the most common form of dementia diagnosed in people over 65 years of age, is a global problem with dramatic impact, as there is no cure for it and worsens as it progresses, eventually leading to death. As the sufferer declines s/he often withdraws from family and society, leading to a marginalized way of living. Considering the life expectancy rise, a looming global epidemic of AD is foreseen; hence, new approaches need to be considered regarding AD prevention, diagnosis, treatment, and confrontation. In this vein, an alternative approach (namely Symbiosis) towards a symbiotic Human-Computer Interaction (HCI) environment is presented in this chapter, as a means to facilitate, understand and incorporate the needs of the whole AD community (i.e., patients, caregivers and doctors), involving cutting-edge technology, special serious games and natural-user interfacing, embedded within an innovative design framework. Overall, Symbiosis acts as a technology-based mediator for AD's indoor and outdoor activities, fostering their social inclusion and increasing their quality of life in a symbiotic context.

Graphics for physicists

While the visualization of data is critical for many scientific applications, the development of programs to render geometrical forms in real time, providing interactive control over viewpoint and angle, animation, and/or user interaction, can be complicated for a scientist. The need to master unfamiliar technology such as graphics engines, windowing software, and graphical user interfaces constitute major challenges. An introduction to the graphical display of data using the Coin3d toolkit for object modeling and rendering is given. The Qt library for graphical user interfacing and the SoQt package, which serves as “glue” between Qt and Coin3d are also presented. Applications to visualizing fractal geometries, three-dimensional objects, and random data are presented.

"Intelligent tutoring in the wild: leveraging mobile app technology to guide live training"

"Mobile computing technologies are extending how people can interact with educational and training content in a whole new way. Through high resolution displays, intuitive user interfacing, embedded sensing technologies, and well supported app development communities, there is a plethora of content that can be used to build effective materials that target knowledge and skill development. To truly enhance this new training paradigm, extending Intelligent Tutoring System (ITS) to support mobile interactions can provide a new means to managing training in a rich contextualized environment. In this instance, learning takes place in the natural environment where directed experiences focus on the elements surrounding one’s location. In this paper, we describe the development of a new mobile ITS application using the Generalized Intelligent Framework for Tutoring (GIFT; Sottilare, Goldberg, Brawner & Holden, 2012). The domain of land navigation was applied as a use case, with direct support for the United States Military Academy at West Point. We describe the training concept, how GIFT was extended to support this concept from an architectural and assessment standpoint, along with implementation plans for an initial training effectiveness study."

Magnetic Induction Tomography: A Brief Review

Magnetic Induction Tomography (MIT) is a contactless non-invasive imaging technique that interested in mapping the passive electrical properties of a material; conductivity, permittivity and permeability. This paper presents the criteria and previous functional specification involving the development of MIT, focusing in conductivity imaging. Various ways have been implemented from a simple electronic configuration of the front-end sensory circuit, data acquisition system, reconstruction algorithm and graphical user interfacing (GUI) tools. Induction sensors are paramount as it does provide the signal source for time varying magnetic field to the coils. The advantages and limitations of MIT are also presented. Many more advancement can be expected to enhance the lack of MIT especially in spatial resolution and dynamic response of the sensor.

Blind User Interfacing

There are specific usability requirements for developing dual interfaces, that is, graphical user interfaces that are also adapted for blind users. These include task adequacy, dimensional trade-off, behavior equivalence, semantic loss avoidance and device-independence. Consequently, the development of human-computer interfaces based on task, domain, dialog, presentation, platform and user models has to be modified to take into account these requirements. This paper presents the requirements for blind user interfacing, the changes to be made to the human-computer interface models and a framework that improves the development of dual user interfaces. The framework includes a set of guidelines for interface design, a toolkit for the low effort implementation of dual user interfaces, and a programming library for the inclusion of speech and Braille in applications. A case study of the development of one such dual interface application is also presented.
