Preservation of sweet red pepper paste quality: effect of packing material, ozone gas and protective agent use

Abstract: Unlike conventional methods, sweet red pepper paste was produced by various techniques in assistance of various starter cultures. Products were stored at 37 °C for 60 days. Salinity, acidity, color change, invert sugar, brown pigment formation parameters were determined during storage period. Microbiological, statistical and sensory evaluation methods were also applied and the effects of Polyethylene Terephthalate (PET) and Polypropylene (PP) at different filling temperatures with and without protective agents were investigated. E. coli was not detected at any production stage. Samples treated with protective agents at higher temperature was found to be best with respect to panelists’ flavor and color quality scores in PP support as a result of deterioration has occurred in samples with PET material. The results provide a basis for increasing active components and functional activity in pepper paste production by controlling packing material and ozone gas release considering chemical and sensory properties.

The comparison of LMS Based Algorithms For Active Cancellation Of Motor Noise

Abstract: In this paper, an active noise cancellation system to decrease the motor noise arriving to car driver is proposed. This system can be considered as a feedforward control system since it enables taking motor noise as the reference signal. The coefficients of adaptive filters in this structure are obtained with LMS (Least Mean Square) algorithm. In this study, both standard (LMS and normalized LMS) and more advanced (variable tap length LMS and variable step size LMS) LMS algorithms are used and their performances are compared. For the different models belonging to different configurations of the system, the acoustic noise simulations, which contains real noise signal belonging to motor of an accelerated car, are realized. According to the results of these simulations, the advanced LMS algorithms are observed to converge more rapidly and have better error performances within whole signal and steady-state as compared to classical algorithms.

An RF anechoic box system development for shielding effectiveness measurements

Abstract: Shielding effectiveness is a term that defines the electromagnetic shielding property of a material. The demand of using wireless technologies and higher frequencies in new devices also bring the need to shield the unwanted electromagnetic fields. Therefore determining the shielding effectiveness of materials becomes an important concept. In this study a compact, low-cost RF anechoic box system for shielding effectiveness is explained. The design and construction of the anechoic box is given as well as the designed printed log-periodic antennas specifically for the measurement system that operates in the frequency band of 750–3000 MHz. The simulation and measurement results of the antennas given. Also, the performance of the whole system is investigated by measuring the shielding effectiveness of an absorber used in the anechoic box with another reference antenna. Open area measurements are compared to the measurements taken in the anechoic box.

Turkish Communication and Media Policies as Reflected in Government Programs: A Historical Analysis between 1923 and 2014

Abstract: The main aim of this paper is to explore Turkish communication and media policies through governmental programs. Governmental programs are valuable sources for tracing the historical development and change of public policies on communication and media. Our research examines 60 governmental programs. We used content analysis methodology in order to examine the communication and media policies in these programs. As unstructured data, the texts of 60 governmental programs (a corpus of 892 pages) are pre-processed (tokenized, stemmed, tagged and cleaned) by KNIME, an open source software for text analysis and data mining. Additionally, we developed a term dictionary for searching communication and media policies. These dictionary terms helped us exploring the themes of governmental policies. Finally, we graphed the data suitably for the historical analysis of themes in order to trace the policy changes. Our research findings helped us to monitor the changes in Turkish communication and media eco-system with regard to specific technologies such as newspaper, radio, television and internet. We also explored certain policy concepts on communication and media freedoms and rights. The analysis revealed that almost all governments included communication and media related issues in their programs, and the amount of references to communication and media policies increased historically. It is also found that the political differences of governments did not cause much difference in their quantitative references to communication and media issues.
