    Opis:
    This paper presents an approach to identify apparel silhouettes. A feature region of the human face was first proposed for conducting face detection in fashion pictures with the AdaBoost method, and the head was then located with its positional relation to the facial feature region. The linear relationship between the ratio of the body height to head length and the length of the lower body was ensured by restricting the RBH to a specific range. Under this condition, the apparelled body was divided into several parts, and the boundary of apparel on the lower body was determined considering the influence of the hemline. Based on the widths of the body parts and the apparel on the lower body, shape factors were established to express the extent to which the apparel silhouette approached a certain shape. A computer program was developed for implementation and demonstrated high accuracy in silhouette identification of an appareled body.
    Przedstawiono próbę identyfikacji sylwetki ubranego modelu. Opracowano system właściwości charakteryzujących twarz człowieka dla możliwości dalszego wyodrębnienia twarzy ze zdjęć modeli. Zastosowano metodę AdaBoost. Umożliwiło to usytuowanie głowy w stosunku do innych elementów ubioru. Zidentyfikowano liniowe zależności pomiędzy wysokościami całości sylwetki, jej dolnej części, i głowy. Na tej podstawie ubrana sylwetka człowieka była dzielona na szereg części i określano granice ubioru w stosunku do dolnej części sylwetki, uwzględniając wpływ dolnej krawędzi ubioru. Opierając się na szerokościach poszczególnych części ciała człowieka i ubioru dolnej części sylwetki, ustalono czynniki kształtu dla możliwości kwalifikacji sylwetki do odpowiedniego typu. Opracowano program komputerowy umożliwiający dużą dokładność identyfikacji sylwetki ubranego modelu.

    Opis:
    The paper presents the results of the project which examines the level of accuracy that can be achieved in precision indoor positioning by using a pedestrian dead reckoning (PDR) method. This project is focused on estimating the position using step detection technique based on foot-mounted IMU. The approach is sensor-fusion by using accelerometers, gyroscopes and magnetometers after initial alignment is completed. By estimating and compensating the drift errors in each step, the proposed method can reduce errors during the footsteps. There is an advantage of the step detection combined with ZUPT and ZARU for calculating the actual position, distance travelled and estimating the IMU sensors’ inherent accumulated error by EKF. Based on the above discussion, all algorithms are derived in detail in the paper. Several tests with an Xsens IMU device have been performed in order to evaluate the performance of the proposed method. The final results show that the dead reckoning positioning average position error did not exceed 0.88 m (0.2% to 1.73% of the total traveled distance – normally ranges from 0.3% to 10%), what is very promising for future handheld indoor navigation systems that can be used in large office buildings, malls, museums, hospitals, etc.

    Opis:
    The treatment effectiveness of Fenton's reagent using Fe2+catalyst to reduce chemical oxygen demand (COD) of skim latex serum and the effect of varying concentrations of H2O2, Fe2+and initial solution pH on its treatment efficiency were investigated. The highest COD removal efficiency obtained was approximately 80% at optimum conditions. The treatment required either nominal or no acidification as initial pH of serum is very close to the optimum pH = 4. COD removal increased upon increasing H2O2 and Fe2+concentrations. This study shows the suitability of using Fenton's process with H2O2and FeCh as a pre-Treatment for skim latex serum. The findings reported here represent a potentially simpler and more cost-effective alternative treatment to other treatment methods since only reagents and not capital-intensive materials (such as membrane) are required.

    Opis:
    The travel time tomography technology had achieved wide application, the hinge of tomography was inversion algorithm, the ray path tracing technology had a great impact on the inversion results. In order to improve the SNR of inversion image, comprehensive utilization of inversion results with different ray tracing can be used. We presented an imaging fusion method based on improved Wilkinson iteration method. Firstly, the shortest path method and the linear travel time interpolation were used for forward calculation; then combined the improved Wilkinson iteration method with super relaxation precondition method to reduce the condition number of matrix and accelerate iterative speed, the precise integration method was used to solve the inverse matrix more precisely in tomography inversion process; finally, use wavelet transform for image fusion, obtain the final image. Therefore, the ill- conditioned linear equations were changed into iterative normal system through two times of treatment and using images with different forward algorithms for image fusion, it reduced the influence effect of measurement error on imaging. Simulation results showed that, this method can eliminate the artifacts in images effectively, it had extensive practical significance.

    Opis:
    282 Potato virus Y (PVY) isolates collected from potato crops in northern and central Poland from 1995 to 2009 were characterized by serological and biological assays. From these, 112 isolates collected from 2006 to 2009 were additionally analyzed by one-step triplex Reverse Transcription-Polymeraze Chain Reaction (RT-PCR). Recombinants of PVY strains predominate among the isolates tested. Using one-step triplex RT-PCR most PVYN-Wi isolates were classified as subgroup PVYNWi-P and most PVYN and/or PVYNTN isolates as the recombinant PVYNTN strain. A recombinant PVYNTN isolate (12/94) and two additional PVYN and/or PVYNTN isolates were not detected by one-step triplex RT-PCR. Twelve isolates were identified as the PVYO strain but PVYN, non-recombinant PVYNTN and PVYC strains were not found. Serological and biological assays of 144 isolates of PVYN-Wi strain showed that 100 isolates were the expected PVYO serotype with vein necrosis (VN) symptoms on tobacco. However, 10 isolates of the PVYNWi-P subgroup exhibited vein clearing (VCl) on tobacco and 2 isolates of the PVYNN242 subgroup unexpectedly exhibited as the PVYN serotype. All the isolates of PVYN-Wi strain induced severe local lesions (LL) on Chenopodium amaranticolor. Out of 126 isolates of PVYNTN strain tested, 76 were typical PVYN serotype with VN on tobacco, but their reactions on C. amaranticolor were different: 13 isolates did not show symptoms, 23 isolates induced weak, and 40 isolates induced severe LL. The remaining isolates of PVYN-Wi, PVYN and/or PVYNTN or PVYO were serologically PVYN and PVYO positive or exhibited unpredictable serological and biological reactions.

    Opis:
    We studied the effect of the donor doping of ZnSe films on their photoluminescence properties. The samples were doped during the molecular beam epitaxy growth, either with gallium or with chlorine. As the dopant concentration dose increases, the intensity of the band-edge emission first saturates, and then quenches in favor of the deep-level photoluminescence band. The main effect of donor doping on photoluminescence is a strong increase in intensity of the donor-bound exciton line, referred to as I$\text{}_{2}$. For Ga-doped films deep-band emission is much stronger, and the I$\text{}_{2}$-line is slightly weaker than for Cl-doped films with comparable doping level. The results confirm the superiority of chlorine over gallium as an n-type dopant in ZnSe. We discuss the photoluminescence results and relate them to deep level transient spectroscopy data obtained on the same samples.

    Opis:
    As a key research objective for low melting explosives and propellants, energetic salts have received worldwide attention. 3-Hydrazino-4-amino-1,2,4triazole (HATr) is an important high-nitrogen compound (73.65% N) with good stability. This paper focuses on the energetic salts which were formed between HATr and picric acid (PA) or 2,4,6-trinitroresorcinol (TNR). Single crystals of HATr·PA and HATr·TNR·H2O were grown and their crystal structures determined at low temperature. They both belong to the monoclinic system, P21/n space group. The thermal characteristics of the two target salts were investigated using DSC and TG-DTG. In addition, the non-isothermal decomposition kinetics, heats of combustion and sensitivity have also been investigated. The detonation pressures (P) and detonation velocities (D) of the salts have been calculated using the K-J equations. The results indicated that both salts have certain potential applications as gunpowder and propellant materials.
