Abstract: The authors of presented research case focused on possibilities of sealing porous as well as non – porous materials and analysed the measured results. It is the second article of the above mentioned authors dealing with sealed joints, however, in this case study the focus was placed on a group of industrially manufactured modified silyl polymer and polyurethane sealants. The research is based on the modified test procedure for the determination of adhesion and cohesion properties during maintained extension at variable temperatures, i.e. a high temperature of (70 + 2) °C and a temperature simulating freezing, i.e. (-20 + 2) °C, according to the European standard EN ISO 9047. The degree of specimen extension was set to amplitude of 20.0 % and the aim of the research case was to discover any differences that might appear in the resistance. The measured results demonstrate that there are significant differences between individual sealants in the results they provide in combination with specific material, e.g. wood appears to be a problematic substrate as well as glass cement or aluminium.

Abstract: The paper introduces the results of research study aimed at sealing possibilities of cement-based substrates. The intention of the presented research is to verify whether the permanent and reliable seal in materials can be implemented even without additional surface treatment. The task is approached experimentally, using test procedures based on relevant European technical standards. The tested substrate is made up of glass-fiber reinforced concrete facade elements intended for the final cladding of buildings without any further surface treatment. The selected substrate is 13 mm thick, one test sample consist of two identical pieces of substrate connected by chosen sealant. A group of ten industrially-produced, commonly available sealants by three manufacturers is included in the experimental measurements. The research brought an answer to the question of the sealing possibilities of an unprocessed structures and also solved the issue of the most suitable type of sealant meant for this purpose.

Abstract: Building reconstruction is rather a broad term encapsulating the implementation of solutions to the unsatisfactory condition of various parts of a built structure, which includes the solution of issues concerning the penetration of undesired humidity in the liquid state through leaks in the building’s outer shell. This contribution deals with issues involved in the sealing of concrete elements in the outer shell structures of buildings using modern sealants. It involves the experimental testing of sealed joints using test samples fabricated from glass fibre reinforced concrete and fibre-cement facade cladding panels in combination with various commonly accessible sealants. The sealants were exposed to tensile stress under various environmental conditions, as well as cyclic stress. The results of the tests provide a comprehensive picture of sealants’ adhesion and cohesion with the test substrates and clearly show the suitability or unsuitability of their application on substrates with cement content.

Abstract: In the past, doctors judged images based on their own medical knowledge. Nowadays, the digital image processing technology can alleviate the burden of judging a large amount of multispectral information and lead to more effective diagnosis of the pathological tissues. In this paper, we propose a new approach of seeded region growing based on extension (SRGBE) to classify tissues from brain MRI. Based on extension, we tried to strengthen the regional definition. First, we use seeded region growing (SRG) to segment brain images. Second, the SRGBE result is further classified by K-means. Finally, we compare the images of gray matter, white matter and cerebral spinal fluid produced by both approaches to demonstrate the performance of SRGBE.

Abstract: The purpose of the present preliminary investigation is to characterize the vibration signal between normal and symptomatic knee joint. Accelerometers were attached to the medial and lateral retinaculum of dominant knee to acquire the vibration signal induced during flexion and extension of leg. Signals were compared in time and frequency domain and statistical analysis were performed using mean, variance, standard deviation, skewness and kurtosis. The results show that the frequency range for the symptomatic VAG signal is higher than the normal. The results confirm that the proposed approach is indeed feasible for the non-invasive diagnosis of knee pathology disorders.

Abstract: It is first extended the log4j and then applied the log file distribution function of log4j in E-Commerce service system in this paper. In this way, it can avoid all log information are centralized interspersed in a single log file, effectively disperse the log information of different concerns, easy to monitor and analyze E-Commerce service system operation status. Key words: Log4j, dynamic log file, extension, e-commerce services

Abstract: Fine Chemicals is an important direction and inevitable trend of development of China's petrochemical industry. In order to occupy the commanding heights of industry development strategy, many domestic chemical companies enhance their ability to resist risks, fine chemical products to take extended strategy. However, due to the fine chemicals own characteristics, while enterprises is in product extension, they are often faced with complex decision problems. Based on all of those, multi-product programs projects preferred aand the main product of the extension when siting evaluation are research.

Abstract: The protection and development of traditional architectural culture and traditional feature area in the process of city renewal is a problem requires prompt solution in the trend of urban construction in China. Different cities have different architectural features. How to extend original urban architectural culture and protect the traditions and features of local architectural culture has become an important subject. This article will take the reconstruction and extension project of Hangzhou Jianlan Middle School as an example to analyze and discuss this subject and propose a practical urban renewal plan with extension of urban architectural culture as orientation.

Abstract: In order to construct B-spline curves with local shape control parameters, a class of polynomial basis functions with two local shape parameters is presented. Properties of the proposed basis functions are analyzed and the corresponding piecewise polynomial curve is constructed with two local shape control parameters accordingly. In particular, the G¹ continuous and the shapes of other segments of the curve can remain unchangeably during the manipulation on the shape of each segment on the curve. Numerical examples illustrate that the constructed curve fit to the control polygon very well. Furthermore, its applications in curve design is discussed and an extend application on surface design is also presented. Modeling examples show that the new curve is very valuable for the design of curves and surfaces.

Abstract: Tourism resources are not only the object of tourism activities, but also is the foundation of tourism existence and development in a country or region. With the development of economy, the progress of science and technology, great change has taken place for tourism resources in new era. It is necessary to refresh the connotation, denotation, and properties of tourism resources, and the concept of sustainable development of tourism resources. It has great significance for the development of tourism theory and industry.
