Despite the economic importance of these businesses and their high failure rate, there are only a few scientific studies that try to investigate software engineering in these businesses. This research, using Grounded Theory research methodology and interviewing nine Iran Web Startup, provides a set of evidence for understanding how software development in Startups is formed. The results show that the top priority of these businesses is to enter the market as quickly as possible so that they can find a product that meets a strong market demand by getting feedback from their customers. However, accelerated time-to-market due to the lack of engineering activities requires the rebuild of the product and workflow before the start of future growth. Manuscript profile -

In a typical backbone network, all the routers and their ports are always active and consume energy. Average link utilization in internet service providers is about 30-40%. Energy-aware traffic engineering aims to change routing algorithms so that low utilized links would be deactivated and their load would be distributed over other routes. As a consequence, by turning off these links and their respective devices and ports, network energy consumption is significantly decreased. In this paper, we propose four algorithms for energy-aware traffic engineering in intra-domain networks. Sequential Link Elimination (SLE) removes links based on their role in maximum network utilization. As a heuristic method, Extended Minimum Spanning Tree (EMST) uses minimum spanning trees to eliminate redundant links and nodes. Energy-aware DAMOTE (EAD) is another heuristic method that turns off links with low utilization. The fourth approach is based on genetic algorithms that randomly search for feasible network architectures in a potentially huge solution space. Evaluation results on Abilene network with real traffic matrix indicate that about 35% saving can be obtained by turning off underutilized links and routers on off-peak hours with respect to QoS. Furthermore, experiments with GA confirm that a subset of links and core nodes with respect to QoS can be switched off when traffic is in its off-peak periods, and hence energy can be saved up to 37%.

In fact, the principal reason for the mentioned integration is that the knowledge management plays a key role in the customer relationship management. The potential of bilateral relationship between these two fields and also the critical function of knowledge management in success of customer relationship management, has attracted the attention of researchers to this matter recently. The term of “customer knowledge management” is the combination of knowledge management and customer relationship management. The customer knowledge management requires applying different approaches through considering wide variety of key variables in these fields. The considered key variables for each customer knowledge management model are different according to its model. Generally, many models have been presented for customer knowledge management, including conceptual, process and system model. In this paper, we intend to develop process model which achieved from combination of business engineering model, six business processes based on customer relationship management systems, and four aspects of knowledge management in principle business activities, namely marketing, sales and services.

The formation of these firms depends on practical ideas of entrepreneur engineers. But most of these entrepreneurs are young graduates who may not have the leadership skills and knowledge required for leading new firms. In KBF engineers design and build things that meet the needs of customers, beneficiaries and ultimately the society. These tasks can only be accomplished by the concerted action of many people aligned and rallied by effective leadership. On the other hand, when faced with many problems in KBF’s initial years, however, many of these firms fail to sustain themselves and fall in to bankruptcy with a high rate and one of the most important factors of these failures is leadership. In this study, based on the engineering approach, a special attention has been paid to the leadership. In this approach, technical abilities and leadership, describe principles of "engineering leadership". By this method, KBF can achieve their targets through the proper rout. On the base of "engineering leadership" approach, this study shows leadership skill training plays a main role in the success of KBF. In addition, this paper suggests to KBF managers a contingency sight to select the best leadership method and proper organization structure based on teamwork for KBF success. Manuscript profile -

This idea shows that there is a need to draw a plan which can meet the needs of the customers and also the plan should be capable to be produced with a competitive cost and quality. Saypa company as one of the greatest car making companies must try hard to produce competitive products and by improving the design of the cars should struggle to reach the best position in the competition. So in order to reach the above-mentioned aims, in this research a merger of the tools for expanding quality proceeds(QFD) and value analysis has been used. Therefore the main goal is to use both QFD and VA theoretically and occasionally. ‘Pride’ as a car with quality problems was chosen and the combined process of QFDVA has been used for designing the outward appearance of this car. Finally, at the end of this research project, one main hypothesis and three subordinate hypotheses has been analyzed . For analyzing the hypotheses the researcher has used a questionnaire among a sample group. For statistical analyses, SPSS software has been used. One of the main problems of QFD is not having the ability to identify the needs of the customers, and that was solved by combining the use of VA technique. Also by using this technique, we can evaluate the value of product designing and we can take action in allocating the resources to identified operations and investments. Manuscript profile -

Paying due attention to customer’s feelings about the product, Kansei engineering is one of the most appropriate methods to improve the quality of product and customer’s satisfaction. In addition to introducing Kansei engineering and its relevant techniques, this paper was aimed at translating feelings and emotional impacts on the design parameters. Reviewing the literature through interviewing Merident Toothpaste customers, 83 Kansei words representing customer’s feelings about the product were identified. After screening, 23 words influencing customer’s feelings were divided into three parts including natural features, apparel ones, and controllable factors in order to obtain more rational coefficients of importance in ANP method. Using ANP and DIMATEL methods, then the Kansei words were graded by the experts of organization; consequently, natural features were considered more important. Employing ANP method in the next step, Merident Toothpaste was compared with the similar products manufactured by 3 main competitors to investigate the advantages and disadvantages with respect to the opinions of customers. Eventually, the final weight and importance of criteria were determined. Manuscript profile -

Studies have shown that, in spite of customer needs, customer sense also plays a major role in designing products. One of the effective ways to identify and use in product design is kansei engineering. In this research, we have tried to use quality function deployment (QFD) and kansei engineering to determine the emotions affecting the design of the product and by combining these two, products can be tailored to meet the needs of customers. The statistical population for the determination of technical properties was the stores that were classified according to the sampling method in each case; a simple sampling method was chosen among buyers. Then, during the interview, 10 prominent vendors with a history of selling health products were used. The technical properties of the product are determined in the form of 21 items and a questionnaire distributed among 50 people in which users were asked to determine what characteristics of the product are more important to them. In this research, firstly, with the help of the previous study, the kansei words were collected in relation to the product, and 13 of them were chosen.

Th MoreThe structure of human knowledge in the fields of humanities and social sciences, including management as a discipline, consists of philosophical assumptions and foundations, scientific principles and theories, and the and practical achievements for solving problems. The philosophical foundations of every knowledge are conventionally composed of elements of value, epistemology, ontology, anthropology, and methodology, which are referred to as the components of scientific paradigm. The new philosophy trend in the recent centuries, has shifted from the positivist paradigm to critical and interpretative paradigms, and is shaped into the context of the postmodern paradigm, the pragmatism tradition, and the complexity theory. Each of the above scientific paradigms has foundations in values, epistemology, ontology, anthropology, methodology and its own research methods. This means that today's knowledge in each field, due to the effects of each conventional philosophy of science paradigms, has led to the production of different scientific principles and theories and the distinctive applied achievements. So, opinions and ideas of the thinkers in each field are different. The shifting paradigm from positivism to interpretativeism not only has contributed to the fields of humanities and social sciences, but also effects the fields of science and engineering, such as, the emergence of fuzzy logic along with mathematical logic in the field of basic sciences, quantum mechanics view alongside Newtonian mechanics in the field of engineering. In this paper, we seek to recognize the knowledge developments roots in the branches of industrial engineering, such as the development of "hard operations research", " soft operations research " and "hard systems to soft systems thinking" and "statistical quality control" To "Total Quality Management". Under the influence of paradigmatic changes, developments have taken place in other branches of knowledge forming the industrial engineering as an interdisciplinary scientific discipline for the future. We also examine the systemic methods paradigmatic foundations influenced by the above paradigms and examine how to influence the methods of analysis and problem-solving methods with respect to the differences in their basics, philosophies and paradigms.

Research institutes design products that are made without the cooperation of the construction engineering firm. The manufacturing institution does not have a common language in the production of the designed product and therefore no production takes place. Design without considering production and supply considerations seems beautiful only for the designer, but in some cases, the production organization is either not able to produce it or has problems in supplying some parts. This research deals with the issue of coordination of design, production and supply, which by examining the literature, its key indicators at the level of research projects and industrial development were extracted and finally ranked with decision models. For the first time, this research examines concurrent engineering in the defense industry and provides a model for the integration of design, production and supply. The indicators of this issue are divided into 4 criteria of product structure and architecture, management, quality and organizational cooperation. The criteria of product structure and architecture are the most important. Manuscript profile -

However, current research does not address a software engineering view on these techniques that support all the software development process. In this paper, we focus on requirement analysis – as the first step of the software development process and present techniques and tools to cover this shortage. In this regard, we provide a set of stable analysis patterns for learning capability of the agents. Stable analysis patterns are a set of meta-classes and their relations to analyze a specific issue in a domain-independent manner. Using stable analysis concepts, namely Enduring Business Themes (EBT), Business Objects (BO) and Industrial Objects (IO), these patterns represent the conceptual model of the learning. In this paper, we also apply these patterns on two case studies to investigate their applicability. These patterns are used as guidelines during analysis of learning. The main advantage of applying the stable analysis patterns in comparison with conventional analysis methods is modeling the knowledge of the learning analysis in addition to the ordinary classes of the domain. In addition, they generate more stable models via considering different levels of abstraction in the analysis. Manuscript profile -

The present paper proposes a new structure for reducing the leakage current in DGJL-FET, which is called modified DGJL-FET. In this structure, the channel doping under the gate is the same as the drain and source doping but higher than the mid-channel doping. The simulation results indicated that reducing the thickness of the doped layer under the gate, D, resulted in the reduced OFF-state current. For the proposed device with 10 nm channel length, the OFF-state current is less than that in the regular DGJL-FET by two orders of magnitude. Performance of the regular DGJL-FET and modified DGL-FET for different channel lengths is compared based on the IOFF/ION ratio, sub-threshold slope (SS), and intrinsic gate delay. For modified DGJL-FET, the mid-channel doping and Dare considered as additional parameters for improving the device’s performance in nanometer regime. The simulation results indicated that in the proposed device with channel length of 15 nm, values of SS and IOFF/ION ratio are improved compared to the regular DGJL-FET by 14% and 106 orders of magnitude, respectively.

This might happen as the result of uncertainty in stakeholder requirements. Uncertain requirements drive a flexible and therefore adaptable architecture to manage risks at run-time. Modeling uncertainty to adapt architecture automatically is an effective solution when requirements change. In order to evaluate requirements and handle uncertainty by modeling and self-managing, it is advantageous to quantify requirements, computationally. This study besides understanding the sources of uncertainty, investigates how to quantify requirements and quality attributes.

When the normal biological process fails for any reason, healing process can cease resulting in chronic wounds. In Addition, the body cannot repair some extensive wounds without problem. These Issues surrounding wound healing as well as increased medical healthcare in this field, developed novel wound therapies. Regardless of the type of these specific advanced wound care methods, the ideal goal would be to regenerate tissues such that both the structural and functional properties of the wounded tissue are restored to the levels before injury. Tissue engineering and stem cells may be the solution. A range of cell based therapies and tissue engineered scaffolds have begun to cross the rift from bench to bedside. These therapies have been heralded as a promising means by which to surpass current limitations in wound management. The wide differentiation potential of stem cells allows for the possibility of regenerating lost or damaged skin, while their ability to immunomodulate the wound bed from afar suggests that their clinical applications need not be restricted to direct tissue formation. The data suggests that the appropriate application of stem cells and scaffolds can accelerate wound healing. The clinical utility of stem cells and tissue engineering has been demonstrated across dozens of clinical trials in wound therapy. Manuscript profile -

To achieve this purpose, the present investigation, using an analytical approach, surveying the history of the above discourse and categorizing the data thus obtained, attempted to review the Islamic education discourse over the past thirty years and critically evaluate its consequences. The results of the survey point to the fact that excessive emphasis on social engineering and attempt at forming a single uniform religious identity, the inculcation of an attitude for imitation through indoctrination, formalism, and a “quarantined” education are the dire consequences of the above discouse.

Social engineering is used in the west for some time to improve the social problems and to manage the institutions of the society better. " Quran and social engineering" has been presented in Iran at a previous time by Dr Soleiman Khakban in order to localize social engineering based on the principles of Islam religion and its use at the service of the Islamic republic of Iran. In my opinion the article has some ambiguities that I examine them in the present article. Methods: My method in this article is critically. in other worlds, critical discourse analysis. I examine the article critically. It seems that it needs a scientific operation. Conclusion: If social engineering becomes localized properly it can remove the social difficulties and it makes the management of the social institutions in Iran better. And finally it can notably help the development and the honor of the Islamic system. But for this purpose it is necessary to remove that propounded ambiguities and "social engineering with Quranic tendency" should be explained and then the way of starting and using of this knowledge should also be defined precisely.

Polymer 3D printing pr Moreچكيده انگليسي Polymer 3D printing is an emerging technology that further research in this field will lead to continuous improvement of polymer 3D printing design performance, which is necessary to push the boundaries in engineering and medicine. Polymer 3D printing provides the possibility of printing low-cost functional parts with various properties and capabilities. Here, by reviewing research on materials, processes and related strategies applied for medical applications, it is presented. Research in materials has led to the development of polymers with useful properties for mechanics and biocompatibility, by tuning the mechanical properties achieved by changing the parameters of the printing process. Polymer 3D printing technologies include extrusion, sheet lamination, Vat photo polymerization, additive layer, powder-based fusion, material projection, direct energy deposition. Thermal and laser inkjet techniques are more common. The two technologies of sheet exfoliation and direct energy deposition have limited medical applications. Which enables the direct deposition of design materials for useful and customized architectures. Design strategies, such as the hierarchical distribution of materials, make it possible to balance contrasting properties. The most investigated medical applications include tissue scaffolds, dental implants, medical education, delivery systems, and drug safety devices. And finally, the challenges and obstacles of polymer 3D printing were studied. Manuscript profile -

Many stakeholders consider these disputes among the most destructive events in the industry. In most projects, there is a possibility of claims from parties, particularly contractors, due to differences in project implementation systems. While eliminating claims is impossible, identifying the primary causes and origins of claims can help prevent them from occurring in projects. This study investigated the causes of disputes and claims by contractors in municipalities. A comprehensive literature review was conducted to identify potential factors affecting disputes and claims. Subsequently, a questionnaire was administered to 20 experts and specialists to validate these factors. The probability of disputes occurring and the average probability of these disputes converting into significant differences between contractors and municipalities were measured using statistical tests. Exploratory factor analysis was employed to classify the factors causing these differences, and the probability of conversion for each group was analyzed. The Analytical Hierarchy Process (AHP) method was used to rank the factors affecting these differences. The results showed that indicators related to the consultant's weaknesses and shortcomings, as well as those related to the employer's weaknesses and shortcomings, accounted for a significant share in the occurrence of disputes between municipalities and contractors. Specific issues such as the execution and timing of projects, duplication of work, delays in decision-making, and delays in obtaining necessary permits were found to contribute to disputes and claims. The study underscores the importance of effective project management, timely communication, and collaboration between contractors and municipalities to minimize disputes and claims.
