A crime prediction model based on spatial and temporal data
Get PDFIn a world where data has become precious thanks to what we can do with it like forecasting the future, the fight against crime can also benefit from this technological trend. In this work, we propose a crime prediction model based on historical data that we prepare and transform into spatiotemporal data by crime type, for use in machine learning algorithms and then predict, with maximum accuracy, the risk of having crimes in a spatiotemporal point in the city. And in order to have a general model not related to a specific type of crime, we have described our risk by a vector of n values that represent the risks by type of crime
Treatment Automatic: Semantics Analysis and Traduction of the Frozen Expression with Nooj
Get PDFThe purpose of this article is to define more closely the notion of freezing which, despite numerous publications in the field, remains a vague concept. The reflections are the result of a research project that aims to build an almost exhaustive database of fixed verbal expressions in English. After a review of the essential properties of the expressions, it is indicated why each of these criteria is problematic. One of the major problems lies in the existence of related phenomena: from a semantic point of view, fixed expressions participate in the general phenomenon of polysemy, lexical solidarity brings them closer to collocations and finally, morphosyntactic fixity is present in many fixed sentences that are conversational routines and even partly in so-called free syntax. 
Sustainability of Traditional Buildings Located in Rural Area
Get PDFIn this days, sensitivity to environmental issues of people increased together with the awareness of the concept of sustainability. The structures, which are built in a rural residential area, are integrated with the natural environment. In Turkey, local traditional structures are structures that can be produced easily in place and materials are being used wisely. These houses which are used renewable natural materials carries a lot of features of the sustainable approach. Traditional structures have been shaped by the region where they are, because of the necessity. In this study, materials and construction systems of the traditional buildings which are located in rural areas are discussed and the buildings have been evaluated the context of ecology and sustainability

Complex Ecological System Modeling
Get PDFIn this paper we extend our previous results in dual approach to analysis and simulation of a complex ecological system of preys and predators. We first define nonlinear dynamic equations Lotka-Volterra Model (LVM) with three preys and three predators and then simulate the equivalent situation with an Agent Based Model (ABM) which models a variety of species attributes and behaviors using NetLogo simulation environment for ABM model. The idea is that the LVM and ABM methods reinforce each other as the predator-prey models become more complex and their dimensionality rises. In particular LVM’s parameters, components of community matrix, can be fine tuned using ABM simulations. Dual approach may be able to answer and qualify some of the long standing ecological paradoxes.
 
A review on Nanoparticle and Protein interaction in biomedical applications
Get PDFNanoparticles are molecules with size depended chemical and pyhsical characteristics, enabling interesting and correlated approaches while dealing with fundamental biological questions. Nanoparticles are capable of strong and important interaction with other molecules. Many different nanoparticles are produced, with variety of different roles, but Gold nanoparticle as metal based beads, have specific importance due to their attractive physical and chemical properties, biocompatibility, and facile surface modification. In general, nanoparticles have the ability to interact with whole physiological surrounding once when they enter human body. In most of the cases, first molecule they interact with are proteins, which are the main constituens of human body and the driving force of most of the biological processes. This understanding of interaction between nanoparticles and proteins represents an important essence for secure and efficient application of nanoparticles. In this regards, several methods for nanoparticle-protein interaction were developed and analysed in this review.Further, this paper reviews the current scientific development in nanoparticle-protein interactions
The Complexity of Mental Disorders
Get PDFUpon completition of human genome project, there has been a huge effort to identify genes that have been associatedto mental disorders like schizophrenia or depression. However, these investigations still remain at theoretical level.Thus, psychiatry does not seem to benefit from postgenomic era as desired. This paper will briefly discuss the reasonsfor this bottleneck in terms of the complexity of mental disorders
Rogue wave recurrence inHEMT
Get PDFThe GaN semiconductor bulk plasma is examined through developing a quantum hydrodynamicmodel and taking intoaccount the electrons/holes degenerate pressure, Bohm potential, and theexchange/correlation effect. The basic set ofquantum fluid equations is reduced to the nonlinearSchrödinger equation (NLSE). Numerical analysis of the latterpredicts the rough (in) stabilitydomains, which allow for the rogue waves to occur. Our results are employed to explorethe GaNhigh electron mobility transistors (HEMTs) and their intrinsic problems in high frequency/powerapplications. Aphysical solution is suggested rather than engineering due to the GaN HEMTsdrawbacks
The role of interactive technologies in improving the quality of learning and development of scientific competences in modern education
Get PDFIn contemporary education, interactive technologies assume a pivotal role in enhancing the learning quality and the development of scientific competencies. This research substantiates their necessity within the educational framework. The study\u27s primary objective was to justify and analyse the role of interactive technologies in improving educational quality, particularly concerning the development of students\u27 scientific competencies. This is achieved by examining their impact on the activation of the learning process, the cultivation of critical thinking, and the enhancement of communication skills. The methodological approach comprised a comprehensive literature review. The analysis encompassed 50 sources from esteemed academic databases, including Web of Science, Google Scholar, and Scopus, with selection executed through stratified sampling. The inclusion criteria encompassed articles published between 2019 and 2024 that investigated both Ukrainian and international research in the fields of pedagogy, psychology, and teaching methodology, particularly focusing on the implementation of interactive methods in instructional practices. The results showed that interactive technologies played a crucial role in fostering active learning, enhancing critical thinking, and building practical skills. The use of case studies in teaching "English for Professional Purposes" positively impacted the understanding of theoretical concepts and improved communication skills. In this environment, teachers assume the facilitators status, while students take an active part in collaboratively creating content. Nonetheless, challenges persist, including psychological barriers and the necessity for adaptation to innovative pedagogical methods. In conclusion, the study underscored that interactive technologies represent an effective instrument for augmenting the quality of education and fostering essential skills. Future research avenues should concentrate on developing models aimed at promoting communicative competence, thereby facilitating the overcoming of communication barriers among students
