Web security is an old yet important topic. With the emergence of new applications and new threats, we need new techniques to fight against these threats. Fuzzing technique has been proven as an effective tool and has the potential of evolving with the new threats. In this paper, we discuss the applications of fuzzing technique in both web and other areas. We also present a case study by implementing a fuzzer in this study.

This paper aims to provide a case study of determining the structure and mechanical Representative Elementary Volume (REV) simultaneously for a specific jointed rock mass. The schist of Danba HPP project is taken as the study case here. A Synthetic Rock Mass model (SRM) is firstly constructed based on sophisticated geological loggings. With which the number of joint centers per unit volume (P30), the area of joint per unit volume (P32), and the Young's modulus (E) are examined for various sample sizes. It is found that the SRM is a powerful tool to address those problems. The P30 reduces gradually with the increase of rock mass scale. As for P32 and E, maximum and minimum value and the variance decrease rapidly with the increase of rock mass size. A comprehensive REV size of 50~60m is then estimated based on the above 3 indexes. According to the SRM simulation, young's modulus of the REV scale is around 6.8GPa, which is a little bit higher than the recommended value by geologists. This difference is believed to be reasonable as the recommended value usually been significantly undervalued. The procedures and findings of this paper may provide a certain reference for further studies on rock mass scale effects.

Dalihan Na Tolu' is the central system in every Batak Toba's ceremony. 'Dalihan Na Tolu' as an idea is related to customs as activities and Batak Toba architecture as an artefact. This research is classified into a study using descriptive research method that is explorative. The benefits of this research are knowing about 'Dalihan Na Tolu' system in Batak Toba customs and the relationship between 'Dalihan Na Tolu' and the architecture of a Batak Toba village in Samosir, Huta Raja, located in Lumban Suhi-Suhi, Samosir. This relationship can be seen in the interior and facade of the traditional house in Huta Raja which contains the 'Dalihan Na Tolu' element in it.

The aim of the research was to elucidate the changes in the subsistence patterns in Meinypilgyno village community located in the South of Chukotka on the Bering Sea coast near a spawning area of the large stock of red salmon. The research was based on modern interviews and data of the Polar Census 1926/27. The result was compared with case study of Chukchi pastoralists and Yupik communities made by Igor Krupnik (1983) in northern Chukotka. The population of Meinypilgyno was formed 90 years ago from two indigenous communities with different subsistence patterns and ecologic niches: Chukchi reindeer herders and Kereck fishermen and sea-mammal hunters. The Soviet and post-soviet economic and social reforms combined with Russian immigration changed indigenous life step by step. First, the Kereks blended in with the Chukchi community, and then the Chukchies lost their reindeer husbandry and began to merge with the Russians. Meinypilgyno became biethnic Chukchi-Russian community focused on red salmon fishing. Presently, both ethnic groups use the same ecologic niche. The analyses of the evolution of the subsistence patterns in Meinypilgyno confirms the thesis that two communities with similar subsistence activities using one ecological niche are going either to clash, or to merge together.

In order to study the spatiotemporal features of urban centre residents during peak hours during workdays and rest days, based on taxi on and off location information and urban points of interest data, a Geographic Information System (GIS) Kernel density estimation (KED) is used. Combined with the K-means clustering algorithm, the peak hours of residents 'travel and hotspot areas for boarding and alighting are identified, and the strength of the interaction between residents in each area is analysis using the structured Georgy Voronoi, and the spatiotemporal features of residents' travel are summarized.

Credit fraud observations are minority in the sample set, variables tend to be seriously unbalanced, and the prediction results tend to be biased towards more observed classes. Common resolution usually constructs 1:1 data, either cutting off part of more classes (undersampling) or reducing classes for bootstrap sampling (oversampling). XGBoost is an efficient system implementation of Gradient Boosting, and also GB algorithm based on CART. Based on the real online transaction data of an Internet financial institution, this paper studies the performance of XGBoost algorithm on the original data set, the undersampling and SMOTE data sets respectively.

The increased applications of technology in the field of architecture, especially digital technology and aspects of automation, have made a major impact on various aspects of local architecture, especially the traditional ones. As these technologies have succeeded in integrating many technological applications in many traditional and heritage buildings and taking them to more complex uses. And included in it characteristics that were not contained, therefore the research problem was concentrated in the absence of a holistic view of the role of the aspects of automation as a technological and design effect and its mutual effects on traditional buildings (especially the traditional Baghdadi houses), in terms of their foundations, indicators and use aspects, where the research aims to apply the characteristics of automation from Through the complementarity of its features, and an attempt to formulate new traditional local architectural text strategically rooted by the technology. This contributes to the advancement of the declining reality of selected models of Baghdadi houses and the attempt to elevate the architecture and use of them through the use of the effects of automation in them. Communication between the past, present and future towards creating a building with a new spirit.

Relational understanding refers to know both what to do and why. In other words, relational understanding is an understanding of all the parts, how they relate, and why they are applied in the manner they are. Previous researches showed that students got difficulties in solving mathematics problem using relational understanding, especially in geometry problems. The purpose of this study was to investigate students’ relational understanding of the rectangle. The subjects of this study were four 8 th graders. The data were collected using the student’s worksheets and interviews. This study was conducted in four meetings for every student. Every meeting was held for 30 minutes. The students’ understanding was appraised during the first ten minutes using the rectangle problem followed by interview for twenty minutes. The result of this study showed that the students do not have a relational understanding of the rectangle concept, but only instrumental understanding. Additionally, none of the students understands the relationship between both measurement and square with the area and perimeter of the rectangle concept. Furthermore, the result indicated that the relational understanding of a concept would be not understood well if one of the parts of the concept was ignored.

Home-Based Enterprise is a business that relies on households [1]. With the existence of dual-function at home, both economic and domestic activities that are mutually mixed will ultimately affect the interiority of its inhabitants. In Indonesia, HBE is one of the implemented business entities, and many of them are engaged in the creative economy sector, one of which is Batik production. The Case Study was one of the HBE houses batik in the Trusmi Cirebon area. In Trusmi, there are many batik artisans use their homes as places to produce batik. The process of Batik Tulis has many process stages and requires considerable space for each stage. The question of this research is what kind of interior adaptation implemented in balancing domestic and economic activities, which is batik creating. This research also identifies the factors that influence the applied adaptations at HBE. The author takes a sample of a house that carry out Batik Tulis production, which involves many processes that occur in one house. In the discussion, the effects of the stages of the batik process on space adaptation applied by the occupants of the house to balance economic and domestic activities will be identified.

Digitalization and internet penetration force telecommunication companies to perform a transformation to survive, to face competitions, and to gain opportunities. PT XYZ is a telecommunication company that has introduced a new leaner and agile working method for digital transformation. The organization is undergoing a transformation to implements an agile approach using a scrum framework. There are two divisions that use scrum that currently plagued with time estimation difficulties and inability to create an agile backlog due to the old change request mechanism. Scrum Maturity Assessment (SMM) is used to measure current scrum practice maturity. The data is retrieved using a questionnaire that was given to two Scrum Master from two divisions which have been implementing Scrum. There are 83 questions derived from SMM assessment questions. SMM assessment indicated the scrum practice is Level 1 (Initial). There are 31.76% of scrum practices in IT division and 36.25% of scrum practices in CS division need to be improved to achieve Level 5 Optimizing. In order to achieve Level 5, we proposed 38 steps and six recommendations which will guide the scrum practice improvement process.
