Face recognition is more advantageous than other biometric systems such as signature, iris scanning, fingerprint, etc. It can apply without cooperation of individuals. Effect of illumination, partial occlusion and different imaging conditions makes face recognition more complex problem. Preposed work demonstrates designing, implementation and verification of a face recognition system under partial occlusion conditions. Face recognition process is composed of image acquisition, face components detection, feature extraction, face recognition and identification of person name. Facial components such as left eye, right eye, nose and mouth are detected with separate detectors developed for every facial component. After the facial components extraction histogram equalization, resizing and vectorizing operations are applied. Feature selection approach is used in proposed technique. Principal component analysis (PCA) is used for feature selection and 1033 features are selected for recognition purpose. First select 2016 features out of 2520. Then select 1613 features from 2016. Finally select 1033 features from 2016 features. Then FeedForward Neural Network is used for classification purpose. MATLAB environment is used for the face recognition process. The experiments were performed on AR face database.

Wood deterioration and degradation are a crucial process on earth which it will promote the recycling of organic and inorganic materials. These process, however, also destroy wooden monuments that have been used as sculpture and historic building resulting aesthetic and structural damage. In recent years, microbial deterioration and degradation present in many historic and significant objects have attracted the particular attention of the archaeologist and microbiologist. The aim of our study was to examine the diversity of microbial communities responsible for the deterioration of the wooden archaeological artworks which built in 7000 cal. BP. For this purpose, the clone library of fungi and bacteria was constructed and 18 microbial strains were isolated and identified from Kuahuqiao and Tianluoshan site. The clone library showed that bacterial diversity was represented by different bacterial phylum such as Proteobacteria, Actinobacteria, Firmicutes, Bacteroidetes, Fibrobacteres. However, Firmicutes was detected to be the predominant bacterial communities of three samples, accounted for 30.12%. In addition, 15 isolated strains were used to detect their abilities to degrade wood and synthetic polymers commonly present in artworks as protective materials. The results indicated few of bacteria and fungi could produce esterase, lipase, endocellulase and ligninase, which may be involved in deterioration of wooden artwork’s structure and protective materials. This is the first time that we carry out study on the detection of microbial distribution in Kuahuqiao and Tianluoshan site. Our investigations provide new information on the potential microbial inhabitants of wooden artworks and synthetic materials.

Considering the impact of the non-linear stiffness dynamic non-linear vibration model with cubic terms was established according to the structural feature and non-linear behavior of the tracked ambulance. In this paper is vibration control of the main system using control at the simultaneous primary and internal resonance , the multiple scale perturbation method is applied to obtain a solution up to the second order approximations. Other different resonance cases are reported and the effects of different parameters are studied numerically. The stability of the system is studied using frequency response curves and phase plane. Comparison between numerical solution and the approximate solution is obtained.

Background. There are differences between the results of studies performed in different centres, regarding the substances responsible for anaesthetic related anaphylaxis. Anaphylaxis due to colloid plasma expanders is a recognized but rare life-threatening complication in patients.\n\nMethods. For 5 years (January, 2009-June, 2013) the patients presenting with perianaesthetic anaphylaxis were analyzed in the Pomeranian area in Poland. The diagnosis was based on case history, skin prick and intradermal tests, specific IgE measurement and serum mast cell tryptase. Reactions were defined as IgE-mediated (anaphylactic-type), if positive skin tests, and/or specific IgEs occur.\n\nResults. Out of 25 referred patients(18 females, 7males, ages ranging between 22 and 67) 5 consented to complete all investigations needed for identifying the gelafusin of the allergic reaction. An IgE mediated mechanism was confirmed in 100% patients. \n\nConclusion. In the all of the 5 cases an IgE mediated mechanism was identified. Patients with suspected allergic reactions during anaesthesia should be referred for investigation in specialist centres whenever possible.
