Publication Metadata only Poster: A Mobile Application for Voice and Remote Control of Programmable Instruments(SPRINGER INTERNATIONAL PUBLISHING AG, 2019) YAYLA, AYŞE; Ece, Burak; Yayla, Ayse; Korkmaz, Hayriye; Auer, ME; Langmann, RThe purpose of this work is to add a new feature to bench-type conventional instruments used in Electrical and Electronics Engineering Laboratory which do not have any voice recognition and wireless communication technology. By this way, the user can control these instruments/devices remotely with voice commands and also monitor the results/values in graphical or numerical/text format as well over a mobile device screen. The only limitation is that such instruments should have a driver supported by any software such as NI LabVIEW and a PC connectivity interface such as USB, GPIB or LXI (LAN extensions for Instrumentation). Controlling the instruments (such as oscilloscope or signal generators which are frequently used for training purposes and whose functions are manually set) over a mobile device with voice commands will make life easier for disabled students who especially have difficulties in using their hands.Publication Metadata only A Remotely Accessible and Configurable Electronics Laboratory Implementation by Using LabVIEW(WILEY, 2010) KORKMAZ, HAYRİYE; Azaklar, Sezen; Korkmaz, HayriyeIn this article, selected applications from the experiments included in undergraduate Electronics and Computer Education curriculum are transformed into remotely accessible and configurable manner. The experiment user interfaces and publishing over the internet is developed in LabVIEW. These experiments are suitable for online conduction where students are either in-class or laboratory on-campus and/or at home. In this work, four different remotely configurable experiment modules are designed and implemented. Remotely configurable facility in a predefined range is performed by using switches activated by DO terminals of a data acquisition card through a web-based application. In this way, students can select the desired experiment from the ones stored on the PCB, adjust the voltage applied to the input terminal of the circuit and change the circuit elements values by using telepresence methodology.

This LabVIEW application performs several tasks as follows: user interface design, publishing and sharing measured data, instrument control, and remote access to system in the campus lab. This paper describes how to control an instrument existing in the laboratory via a PC on-lab or on-line by using instrument drivers in LabVIEW. Readers can also find the information about where to find and how to download instrument drivers provided by NI or other vendors. In addition, how to turn any LabVIEW application into a remote application accessed via a Web browser without any additional development time is explained in detail. The instruments used in the work are a dc power supply and a data acquisition/ switch unit (multimeter) which are remotely controllable ones having a GPIB interface. Ensuring instrument control and publishing the front panel on the web, students are allowed to access and control the system variables such as adjusting dc power supply’s output to a desired value by clicking the knob or dragging the slider position up/down on the user interface seen on client PC’s monitor.Publication Metadata only A USB Kit for Digital I/O Applications in a Digital Electronics Lab Designed by Using PIC16C765 Microcontroller(WILEY, 2009) BULDU, ALİ; Buldu, Ali; Korkmaz, HayriyeIn this article, a USB Kit is designed by using Microchip's PIC16C765 microcontroller that has a low-speed USB serial interface engine. It is used to communicate with and/or through USB port for digital I/O applications in a Digital Electronics Lab In this education kit, two groups of keys (switches) and a group of LED are used to realize the experiments about logic gate applications included in Electronics and Computer Education Department's curriculum of Marmara University and also included in other faculties' curriculums related to the engineering science all around the world. In designed board, one of the key groups is 8-bit software-controlled by using simulator interface and the other is 8-bit user-controlled by using real switches existing on the board.

Nevertheless, exhaust emissions of conventional internal combustion engine vehicles are the major source of global warming lead greenhouse effect. One solution for this issue is hybridization/electrification of the vehicles. One of the most important tools which can help to test performances of technical solutions systematically is driving cycles representing real driving conditions for vehicle emissions testing and estimation. When the history of the driving cycles was reviewed, it can be seen that there were big changes from constructing synthetically to real world cycles and from emission-focused cycles to emission, pollution and fuel consumption focused cycles. And now, a new application such as hybridization and/or electrification has been added to driving cycles. Main aim of this study is to create a practical driving cycle for Bus Rapid Transit (BRT) vehicles. To do this, characteristic driving parameters such as speed, distance, time, acceleration have been determined first. Data acquisition from conventional vehicles running on Istanbul route was performed and then data were analysed. A driving cycle was developed by using Proportional Stratified Sampling (PSS) technique. Comparison between constructed driving cycle and the real-world data show that difference is less than 10%. And so, it can be concluded that proposed driving cycle was acceptable.Publication Metadata only Production of the go-doped pla-based nanofibers and investigation of their electrical properties(2018-07-18) TERZİ, ÜMİT KEMALETTİN; KORKMAZ, HAYRİYE; EKREN, NAZMİ; GÜNDÜZ, OĞUZHAN; CESUR, SÜMEYYE; Özen S., Aydoğdu M.
