Counting of RBCs and WBCs in noisy normal blood smear microscopic images
This work focuses on the segmentation and counting of peripheral blood smear particles which plays a vital role in
medical diagnosis. Our approach profits from some powerful processing techniques. Firstly, the method used for
denoising a blood smear image is based on the Bivariate wavelet. Secondly, image edge preservation uses the Kuwahara
filter. Thirdly, a new binarization technique is introduced by merging the Otsu and Niblack methods. We have also
proposed an efficient step-by-step procedure to determine solid binary objects by merging modified binary, edged
images and modified Chan-Vese active contours. The separation of White Blood Cells (WBCs) from Red Blood Cells
(RBCs) into two sub-images based on the RBC (blood’s dominant particle) size estimation is a critical step. Using
Granulometry, we get an approximation of the RBC size. The proposed separation algorithm is an iterative mechanism
which is based on morphological theory, saturation amount and RBC size. A primary aim of this work is to introduce an
accurate mechanism for counting blood smear particles. This is accomplished by using the Immersion Watershed
algorithm which counts red and white blood cells separately. To evaluate the capability of the proposed framework,experiments were conducted on normal blood smear images. This framework was compared to other published
approaches and found to have lower complexity and better performance in its constituent steps; hence, it has a better
overall performance

Essence and need of creating image of higher education school
W pracy przedstawiono rolę komunikacji marketingowej w budowaniu wizerunku uczelni oraz główne jego elementy. Potrzeba budowania pozytywnego wizerunku wynika z niematerialnego i specyficznego charakteru usługi edukacyjnej, narastających trudności z pozyskaniem jej odbiorców oraz silnego uzależnienia pozycji uczelni od podmiotów otoczenia. Opisano badania potwierdzające decydujący wpływ wizerunku uczelni na wybór miejsca studiów. Zwrócono uwagę, że pozytywny wizerunek jest również podstawowym warunkiem realizowania przez uczelnię misji społecznej.The article describes the role marketing communication plays in creating an image of a higher education school as well as its main components. A need to create a positive image results from the immaterial and unique character of an educational service, increasing difficulty in attracting clients and strong dependence of the school’s position on its environment. The results of the survey conducted among students confirm the decisive influence of an image on the choice of a higher education school. A positive image also constitutes the fundamental condition for fulfilling the social mission of a higher education school
Impact resistanse laminates used to transport vehicle of bodywork parts
Powszechnie stosowane na osłony, zderzaki, obudowy maszyn i urządzeń laminaty poliestrowo-szklane z racji pełnionej funkcji są narażone na różnego rodzaju dynamiczne oddziaływanie siły skupionej. Uderzenia często mają charakter powtarzających się cyklicznie zdarzeń. W artykule zaprezentowano wyniki badań dotyczące laminatów poliestrowo-szklanych wzmocnionych matami oraz tkaninami poddanych kilkudziesięciokrotnym uderzeniom. Zastosowano znormalizowaną metodę spadającego grota, metodę stopniowego wyznaczania. Wyniki pomiarów wskazują na dużą odporność na przebicie laminatów wykonanych z tkanin szklanych, równocześnie wskazują na znalezienie rozsądnego kompromisu pomiędzy laminatami o znacznej sztywności, tańszych, wykonanych z mat, a dużą wytrzymałością na uderzenia laminatów o stosunkowo niskiej sztywności przy małej liczbie warstw tkanin, przez to tańszych.Commonly used on the cover, bumpers, machinery and equipment enclosures polyester-glass laminates because of their function are exposed to various types of dynamic interaction of concentrated force. Strokes often are cyclically repeated events. The article presents the results of research on fi berglass reinforced mats and textiles of glass fi ber treated multiple repeated impacts. Used a standardized method of falling the mainsail, progressive method of selection. The measurement results indicate a high resistance to puncture laminates made from glass fabric, while point to fi nd a reasonable compromise between the laminates of substantial the stiffness, cheaper, made of a mat, and the high impact resistance of laminates with relatively low the stiffness at low number of layers of fabrics

Application of pattern recognition techniques for the analysis of thin blood smear images
In this paper we discuss applications of pattern recognition and image processing to automatic processing and analysis of histopathological images. We focus on counting of Red and White blood cells using microscopic images of blood smear samples. We provide literature survey and point out new challenges. We present an improved cell counting algorithm
