Admission-discharge-transfer gateway interface: A health level 7 application
(2010) Ünlütürk, Mehmet Süleyman; Atay C.
This paper presents a software application called Admission-Discharge- Transfer (ADT) Gateway Interface. This interface uses the Health Level 7 (HL7) standard to bridge the hospital computer systems for maintaining hospital bed occupancy.1 ADT Gateway Interface is a Microsoft VB.NET application that utilizes the Microsoft Windows TCP/IP socket to communicate with the Hospital Information System (HIS) ADT System. Received messages are processed using a custom Microsoft Windows DLL called HL7Messaging DLL and information presented inside these messages are put into a Microsoft SQL Server 2005 database. Hospital computer systems reach to this SQL Server 2005 database to examine the bed occupancy in the hospital. Furthermore, states and errors of this ADT Gateway Interface are recorded. This helps design engineers in measuring performance and observing failures and recoveries. This may require detail log information from this application. In this study, a robust logging viewer design methodology is used to improve reliability and consistency of the overall integrated system.

A Comparison of Neural Networks for Real-Time Emotion Recognition From Speech Signals
(2009) Ünlütürk, Mehmet Süleyman; Oguz K.; Atay C.
Speech and emotion recognition improve the quality of human computer interaction and allow easier to use interfaces for every level of user in software applications. In this study, we have developed two different neural networks called emotion recognition neural network (ERNN) and Gram-Charlier emotion recognition neural network (GERNN) to classify the voice signals for emotion recognition. The ERNN has 128 input nodes, 20 hidden neurons, and three summing output nodes. A set of 97920 training sets is used to train the ERNN. A new set of 24480 testing sets is utilized to test the ERNN performance. The samples tested for voice recognition are acquired from the movies " Anger Management" and " Pick of Destiny" . ERNN achieves an average recognition performance of 100%. This high level of recognition suggests that the ERNN is a promising method for emotion recognition in computer applications. Furthermore, the GERNN has four input nodes, 20 hidden neurons, and three output nodes. The GERNN achieves an average recognition performance of 33%. This shows us that we cannot use Gram-Charlier coefficients to discriminate emotion signals. In addition, Hinton diagrams were utilized to display the optimality of ERNN weights.

A mobile patient monitoring system using RFID
(2010) Korkmaz I.; Atay C.; Kyparisis G.
In the last decade, Radio Frequency Identification (RFID) has become popular in so many fields from military to industry applications. RFID tags have been embedded into many various products especially in logistics sector. A tag stores individual information of its attached object and an RFID reader communicates with the tag in radio frequencies to identify the object. This object to be monitored may also be a human. In our work, RFID technology is applied in health care systems. The system supports wireless mobile communication between the RFID tags and readers. Each patient available in the system is inherently mobile and wears a bracelet integrated with a unique tag, and the readers are mobile PDA devices each including a wireless RFID reader card. The proposed application can be used to identify and monitor the patients.
Real Time Transaction Server
(2010) Ünlütürk, Mehmet Süleyman; Atay C.
In this paper, a windows server is designed to facilitate communication in a complex system such as hospital information system. The server has a Publish - Subscribe architecture that acts like a network router. Each client in the system sends its events with an event type. These events are received by any other client in the system which has a subscription to a channel that includes that event type. With this architecture, a client needs to open a single socket link to the real time transaction server (RTTS), regardless of the number of event types. This eliminates the burden of opening and maintaining multiple links for communication needs that are inherent in a complex system. Communication overhead is further reduced by providing a client control windows DLL that exposes a small set of methods, properties and events to connect, send and receive events from the system through RTTS.
Supervising event executive
(2010) Ünlütürk, Mehmet Süleyman; Atay C.
There are many advances in nurse-call devices but there is a lack of proper integration and interoperation among them. This paper presents a software application to join these devices together in a LAN environment such as Hospital Information System. This software application is called Supervising Event Executive (SEE) that is developed to provide a common, convenient, and reliable means of transferring system events (and commands). The SEE primarily supports four types of applications. First type is called event publisher that generates LAN events from devices. Second type is called event subscriber that consumes LAN events from devices. A subscriber application typically takes some action based on an event. Third type is called resource provider that provides resources or services to consumer applications. The resource provider is typically managed through commands in a request / response nature. In addition, the resource provider may also publish events regarding the status of managed resources. The final type is called resource consumer that consumes resources or services managed by 'Resource Provider' applications. ©2009 IEEE.
