    Intrusion detection in wireless sensor networks
    (2007) Nguyen H.N.; Palaniappan R.; Aydin N.; Jin S.; Turgut D.
    There are several applications that use sensor motes and researchers continue to explore additional applications. For the intruder detection application, we use a set of Berkley mica2 motes on TinyOS operating system. Different types of sensors such as pressure, light, and so on can be used to identify the presence of an intruder in the field. In our case, we choose light sensors for the detection. When an intruder crosses the monitored environment, the system detects the changes on the light values. Any change greater than a pre-defined threshold indicates the presence of an intruder. An integrated webcam is used to take snapshot of the intruder and transmit the pictures through the network to a remote station. The basic motivation of this paper is that a sensor-based web system can be used to detect any intruder in a specific area from a remote location.

    Mathematical model of proctor timetabling problem
    (Curran Associates Inc., 2017) Aksu O.R.; Aydin N.
    This paper provides an optimization model to assign proctors to exams, hence, creates different timetables for each proctors for the entire exam period. The study was carried out in a private university in which the timetabling process used to be done manually. The objective of the model is to create a fair distribution of exams among proctors, with respect to their academic title. That is to say each research assistants, associate professors or professors should have the same amount of duties with their colleagues. Other than the usual constraints of timetabling problem, the model also takes the absences of the proctors into account.
