    Specific Absorption Rate (SAR) analysis is a vital part of compliance tests for commercial mobile phones performed in accordance with the set of comprehensive standardized practices provided by authoritative bodies. Dependence of SAR on a variety of parameters with the structure of the handset pronounced the most calls for bringing in the SAR analysis of various types of phones into the field of study for reference. This paper focuses on the SAR analysis of a PIFA based mobile phone antenna when operated next to standardized and anatomically correct head models. The effect of averaging method used positioning of the phone frequency of operation and the presence of a homogeneous hand model on SAR is investigated along with the antenna performance in terms of terminal and radiational characteristics.

    In this study a new mixing method for mayonnaise was developed. A chaotic hand mixer was designed. The speed of the mixer rotor was chaotically changed with the proposed method. Performance of the mixed mayonnaise was evaluated by a rheological characterization method. The results showed that the proposed chaotic mixing for mayonnaise has a better performance in terms of energy efficiency than conventional mixed ones indicating potential use in industry or as home appliance.

    Size-Reduced Printed Log Periodic Dipole Antenna with Single First Order Semi-Circle Iteration and Feed Point Patches
    (IEEE, 2017) Mehmet Can Ozgonul; Mustafa Secmen; Seçmen, Mustafa; Özgönül, Mehmet Can
    This paper presents the miniaturization and improvement of a printed log periodic dipole antenna (LPDA) by using patches at the feeding point and single first order semicircles. After the design of a conventional printed LPDA on FR4 substrate to cover L-band is performed patches having 12 mm x 5 mm dimensions are placed to the feed point of the antenna. Although this modification gives same antenna size it brings considerable increase in the return-loss bandwidth up to 2.25 GHz and higher gain values up to 2 GHz at the expense of decrease in gain at about 2.4 GHz. Afterwards in order to reduce the total size of the antenna single semicircles are substituted into the dipole arms which results in 14% lateral size reduction. Besides the bandwidth is further improved between 0.9 GHz and 2.4 GHz with better return loss performance higher gain at 2.4 GHz and lower gain variation.
