        Due to the increase in the computational power of computers and the number of servers on the Internet, such as web servers, a problem called C10K emerged. The problem considers to actually handling10000 clients simultaneously through a Gigabit Ethernet pipe. For solving this problem, some non/blocking methods were proposed. We are going to investigate and compare these methods in highly concurrent workloads. One of the most important reasons for wasting the processing power is communication between computation units and using blocking model in the style of programming because if our programs operate in non-blocking mode they can perform other works until the I/O operation is complete. Threads are widely-used tools for concurrency, but huge resource consumption and some limitations such as scalability in many systems due to the threading model has made researchers to focus on new techniques for example, the integration between thread-based concurrency and event-driven concurrency that is results in constructing hybrid systems. The current seminar presents a number of architectures for handling massive concurrency and load, and makes comparison among them. Manuscript profile

        Extensive outcrops of Eocene flysch deposits are available in the Khash area, south-east Iran. These flysches comprise sedimentary cycles of marl, shale, siltstone, and sandstone with erosional structures such as groove and flute casts. The studied sediments are deposited as a result of event-sedimentation. Diverse graphoglytids have been collected from an outcrop of these sediments, located 15 Km west of Khash. Seventeen ichnogenera have been determined among the studied deposits. Most of these trace fossils were formed in the pre-event sedimentation phase on the muddy substrates, and they include Desmograpton, Helminthorhaphe, Paleodytion, Protopaleodictyon, Scolicia, Spirophycus, Spirorhaphe, Squamodictyon, Urohelminthoida. Post-event trace fossils are low in ichnodiversity and form in the sandy or silty substrates, they consists of Halopoa, Helicodromites, Helminthopsis, Nereites, Paleomeandron, Phycosiphon, and Planolites. Some of the trace fossils such as Paleodictyon are aligned with respect to the paleocurrent directions, and were affected by the currents. It seems that fine-grained pre-event sediment surfaces was favorite for K-strategist, while post-event sediments were occupied by R-strategist trace-makers. Manuscript profile

        3 - Analysis on the Structure and Pattern of Drama in “Haft Lashkar” (Comprehensive Scroll of Rhapsodists)
        Atefe  Nikkhoo Yadollah  Jalali Pandari
        Haft Lashkar, (/hæft læ∫kær/: The Seven Corps) is one of the instances of “Comprehensive Scroll of Rhapsodists” during the Qajar dynasty which has been written by an anonymous rhapsodist in 1292 (Lunar Hijri) (1875 A.D). Haft Lashkar has originally been the name of one More
        Haft Lashkar, (/hæft læ∫kær/: The Seven Corps) is one of the instances of “Comprehensive Scroll of Rhapsodists” during the Qajar dynasty which has been written by an anonymous rhapsodist in 1292 (Lunar Hijri) (1875 A.D). Haft Lashkar has originally been the name of one of the famous rhapsodic battle- narratives which was chosen as the title of one of the scrolls of Comprehensive Scroll of Rhapsodists due to its fame and prevalence. The narrative aspect of the text creates relation and connection between literature and drama. This type of storytelling that involves drama and playing the roles of different characters by the narrator, and imitating their manners and moves has led the storytelling towards a kind of dramatic narrative which is called “Dramatic Storytelling”. Meanwhile, although the rhapsodist has considered using the old narrations as a model, his subjective and structural manipulations add a dramatic feature to the text. Thus, because of the dramatic capacity of the scrolls, in this article the dramatic structure of the Comprehensive Scroll is studied. First, by defining the structure of dramatic play and identifying the differences between this structure and the narrative structure in this scroll, a specific model is introduced and explained. Eventually, applying Bart’s structural model of “episode” as involute events, the results of this research, has led us to the “narration-through-narration” event-oriented drama structure, which is different from the climatic drama in the Comprehensive Scroll of Rhapsodists, which has been illustrated in a table and a drama- narrative graph. The dramatic basis of this kind of narration has been revealed through action enhancement as well as increasing interaction between especial roles in the main narration in the form of an event-oriented drama. some suspense features resulted from this type of drama structure are: Using convergent events and developing the depth of the drama, and audience’s focus on the state of the events during the drama instead of concentrating on its ending. .

        Nowadays, Security Information and Event Management (SIEM) is very important in software. SIEM stores and monitors events in software and unauthorized access to logs can prompt different security threats such as information leakage and violation of confidentiality. In this paper, a novel method is suggested for secured and integrated access control in the SIEM. First, the key points where the SIEM accesses the information within the software is specified and integrated policies for access control are developed in them. Accordingly, the threats entered into the access control module embedded in this system are carefully detected. By applying the proposed method, it is possible to provide the secured and integrated access control module for SIEM as well as the security of the access control module significantly increases in these systems. The method is implemented in the three stages of the requirements analysis for the establishment of a secure SIEM system, secure architectural design, and secure coding. The access control module is designed to create a secured SIEM and the test tool module is designed for evaluating the access control module vulnerabilities. Also, to evaluate the proposed method, the dataset is considered with ten thousand records, and the accuracy is calculated. The outcomes show the accuracy of the proposed method is significantly improved. The results of this paper can be used for designing an integrated and secured access control system in SIEM systems.

        Cancellation is reached when both parties have consent over the termination of the contract. This means the end of the contract effects and the resulting commitments. This, however, relates to the future; therefore, it is not like nullification of the contract. It does not have retrospective impact, and consequently it does not affect the pre-cancellation consequences. This point has been neglected by some and in their explanation of rules regarding provisos after cancellation they maintain that all conditions are nullified including attributes, performance and collateral events. Pursuant to this, the Civil Code in Article 246 stipulates that when a contract is terminated by mutual consent, its terms become null and void, whereas rules regarding and effects of each proviso are different and Article 246 shall not be attributable to all of them. This means that the condition of attribute is not within the prerogative of the said article and hence it is not nullified, but also it returns to the initial owner according to the subject of transaction. The condition of collateral events, due to its certain characteristics, is realized immediately after the conclusion of the contract, thus it cannot be nullified or waived either. In the meantime, only the condition of performance, either negative or positive, is nullified due to cancellation although it leaves behind consequences that are analyzable. Manuscript profile

        All service and manufacturing businesses are resilient and strive for a more efficient and better end in today's world. Data mining is data-driven and necessitates significant data to analyze the pattern and train the model. Assume the data is incorrect and was not collected from reliable sources, causing the analysis to be skewed. We introduce a procedure in which the dataset is split into test and training datasets with a specific ratio to overcome this challenge. Process mining will find the traces of actions to streamline the process and aid data mining in producing a more efficient result. The most responsible domain is the healthcare industry. In this study, we used the activity data from the hospital and applied process mining algorithms such as alpha miner and fuzzy miner. Process mining is used to check for conformity in the event log and do performance analysis, and a pattern of accuracy is exhibited. Finally, we used process mining techniques to show the deviation flow and fix the process flow. This study showed that there was a variation in the flow by employing alpha and fuzzy miners in the hospital. Manuscript profile

        Natural Disasters have always been a part of life on our planet. With human society development, urban areas and Metropolises have not been safe from destructive effects and consequences of disasters. In addition to intensity and extent of disasters, vulnerability of societies has remarkable dependence on proper urban infrastructures, strong structures, preventive programs and appropriate preparation in emergency-related organizations. Occurrence of an onset disaster like earthquake, usually leads to secondary damages in urban areas; they happen for an obvious reason and have specific outcomes. Identification of all significant reasons and consequences results in creating a vulnerability map for urban wards which could be a useful basis for preventive programs. On the other side, one of the most effective and efficient approaches to create preparedness and response plan disaster management organizations, is designing a relief chain with proper logistic modules and devoting responsibilities to authorities, based on data achieved from damage estimation studies. Hence, in this paper, a sequential approach is used to apply geographic information system and eliciate experts' knowledge of urban areas so as to create both damage estimation and vulnerability maps; These information. In turn, help designing disaster management cycle, specifically, Preventive, preparedness and response programs for an urban area. In order to create a better perceptive of the proposed approach, Tehran municipality district (1) is used as a real case study and its vulnerability to a hypothetical earthquake is estimated to create disaster management program.

        The environment is one of the most important factors in education. Considering the characteristics and criteria of environmental design can construct new understandings and knowledge for learners. This study aims to present a theoretical strategy for creating an event-based architecture education environment using constructivist theory. The research question is what are the characteristics of appropriate architectural education spaces with event-based and constructivist education? This research is qualitative with practical consequences. The descriptive survey goal is cross-sectional in terms of time and inferential regarding logic. The indicators of constructive and event-based educational environments are identified from theoretical studies. Global experiences of constructive-learning environments have been explored. Then, Shiraz universities' graduate students, educated in the third and fourth semesters, have been selected as a sample. And the criteria of constructivism in their educational environments have were assessed with the tools of observation and questionnaire. After identifying and prioritizing the challenges, solutions were provided to create event-based learning environments. The results indicate that the lack of relationship between the educational environment and the work environment is the most important factor in the inefficiency of the university environment. Cooperation with libraries, museums, construction workshops, and urban spaces and equipping spaces for simultaneous use of city's universities, holding exhibitions, and group judging between different universities can be influential by applying constructivist theory to increase the efficiency of academic environments.

        The use of new approaches and technologies in the design of maintenance plans and policies, taking into account the changes and growth of technology, is one of the factors that are increasingly considered by experts today, and in addition to reducing costs Repair, reducing downtime of machines and increasing the useful life of machinery and equipment, create a competitive advantage in production systems. The purpose of this study is to provide a model for realizing a proactive maintenance approach. In this regard, the decision-making problem for "selecting maintenance policies and programs at the optimal time with the lowest cost" has been modeled. For conducting research, historical data related to the implementation of maintenance programs and risk assessment in the gas pipeline network have been used, and based on recursive induction in stochastic dynamic planning with Markov decision-making process in finite time, mathematical model is designed. In this research, to assign each of the specified policies and actions related to the maintenance program to the identified risks and defects, simulations and optimizations based on time and cost have been performed and sensitivity analysis and validation of the model are performed. The rate of improvement and the rate of optimization in the cost of implementing maintenance policies and the time of its implementation, indicate the efficiency of the proposed model.

        Jamaspnameh is a treatise that is among the works whose author is unknown. The remarkable and final part of this treatise is related to the resurrection and salvation of Zoroastrians, and in this section, the author quotes the events that occur during the advent of Hoshidar, Hoshidar Mah and Sushyant in Iranshahr from the language of Jamasp. The last two chapters of the book are very similar to Zand and Hooman Yassin. In fact, the oldest semantic tendencies in Zoroastrian literature are consistent with the myths of Goshtasp and Jamasp. The concluding section of the Epistle is about the history of revelatory ideas and their flourishing in the first centuries of Islam. This section lists the turmoil and revolutions that will befall mankind at the resurrection and the end of time. But in Christ and the Fourth Gospel or the Gospel of John, where the writings of a person named St. Paul speak from a different perspective, it is believed that Jesus (pbuh) is a celestial being, he descended to earth and is the one who Can "have the glory of the Father before the creation of the world, and in the Torah and the beliefs of Judaism, as well as the view of the early Christians, Jesus (pbuh) is a prophet, he is infallible and is considered the savior of the Jewish people.

        The recording of oceanic anoxic event al record and the time of this event in the shallow carbonates of the Dariyan Formation in Zargran mountain (Gadvan) section in the east of Shiraz, was studied based on carbon and oxygen isotopes, microfacies and fossil data. In this section, thickness of the Dariyan Formation is 287 m and 191 samples were taken. Based on field data, the sedimentary sequence of this formation, , begins at the base with thick-layered to massive gray limestones containing orbitolinas and rudists, and in the upper parts it includes medium to thick-layered gray limestones including abundant benthic foraminifera, such as orbitolinas. In the mentioned section, based on the study of the embryonic cells of orbitolinas, a late Barmian-early Aptian age was determined for the lower part of this unit, which is the beginning of the formation of anoxic oceanic deposits. The carbon isotope curves between the C3 and C6 curves in the carbonates at the base of the Daryian Formation show disturbances. These changes and the appearance of the Lithocodium-Bacinella facies in this part of the formation confirm the existence of an oceanic anoxic event. The oceanic anoxic event indicates warming of the environment and greenhouse conditions, which was accompanied by abundant rudists in this section and can be a confirmation for the weather conditions of this event.

        One memory type which is particularly important in the correct performance of a nurse is prospective memory. Most of the times, the correct performance of a nurse and as a result their patients’ health and life depends on the health and accuracy of their memory. The objective of this study was to investigate the relationship between work motivation and gender with prospective memory performance in nurses. The present research was a causal-comparative study. The statistical sample of the research consisted of 110 nursing students working in Zanjan hospitals. A simple random sampling method was used to select the subjects. The research tools were Hockman and Oldham's job satisfaction questionnaire and the researcher-made task. In order to create forgetfulness in people in the studied groups, a researcher-made task was used, which included 12 nursing activities, 6 time-based activities, and 6 event-based activities. The outline of this test was taken from DMDX software which McFarland and Glisky (2009) had used to evaluate time-based prospective memory. Independent t-tests and MANOVA tests were used to analyze the data. The findings indicated that there is a significant relationship between work motivation and prospective memory; in such a way, nurses who had a higher work motivation showed better performance in prospective memory tasks, both time- based and event- based.

        The present article with the title "Description of apocalyptic events and events in Jamasb-nameh" deals with the investigation of apocalyptic events in Jamasb-nameh. Jamasab Nameh is a book that describes events and events of the end of time from the language of Jamasab, the wise minister of Ghastasab. Zoroastrians believe that the history of the world lasts twelve thousand years. After the battle between good and evil, evil is defeated and goodness covers the whole world. But before the reconstruction of the world, events will take place during the period of each of the founders and saviors, which will cover the whole world with despair and hopelessness. Suchians is the last savior who has enemies and many events happen in his time, but in the end he is defeated by Brahariman. Manuscript profile

        <p>The concept of space and time are intertwined as dimensions of the natural world, the study of each is dependent on the study of the other in order to obtain a better and greater understanding of both. For a better and more complete explanation of the discussion of space and time, we need a discussion of movement, and of course this relationship is two-way, and it is not possible to talk about movement without discussing the discussion of space and time. The aspects of the prism of space, time and motion are invalid without explaining the other two clauses. The purpose of this research is to compare the views of Mulla Sadra essential movement and Einstein's theory of relativity in terms of force, action and event (time-space) and the research is descriptive. It is analytical. The method of collecting information is a library, which has been done by referring to the relevant libraries, extracting files from Mulla Sadra works, articles and other written works on the topic of research. The findings indicated that Sadr al-Mutalahin believed that the essence of things is in motion, and if the essence of things was not in motion, there would be no movement in their symptoms. Because the existence of substance and width outside of our imagination is one and the movement of modernity is existence. There are two types of existence: fixed existence and fluid existence, the existence of the natural world is fluid and modern, which gradually comes into existence and disappears, and at the same time, its unity and personality are preserved. "Einstein" also considers time as the amount of movement and generalizes movement in all universes. And that's why he considers time and space together and to measure anything, he considers time as a fourth dimension.</p> Manuscript profile
