The purpose of this paper is to design a kernel convolution processor. High-speed image processing is a challenging task for real-time applications such as product quality control of manufacturing lines. Smart image sensors use an array of in-pixel processors to facilitate high-speed real-time image processing. These sensors are usually used to perform the initial low-level bulk image filtering and enhancement.

In this paper, using pulse-width modulated signals and regular nearest neighbor interconnections, a convolution image processor is presented. The presented processor is not only capable of processing arbitrary size kernels but also the kernel coefficients can be any arbitrary positive or negative floating number.

The performance of the proposed architecture is evaluated on a Xilinx Virtex-7 field programmable gate array platform. The peak signal-to-noise ratio metric is used to measure the computation error for different images, filters and illuminations. Finally, the power consumption of the circuit in different operating conditions is presented.

The presented processor array can be used for high-speed kernel convolution image processing tasks including arbitrary size edge detection and sharpening functions, which require negative and fractional kernel values.

The purpose of this study is to propose a pulse width based, in-pixel, arbitrary size kernel convolution processor. When image sensors are used in machine vision tasks, large amount of data need to be transferred to the output and fed to a processor. Basic and low-level image processing functions such as kernel convolution is used extensively in the early stages of most machine vision tasks. These low-level functions are usually computationally extensive and if the computation is performed inside every pixel, the burden on the external processor will be greatly reduced.

In the proposed architecture, digital pulse width processing is used to perform kernel convolution on the image sensor data. With this approach, while the photocurrent fluctuations are expressed with changes in the pulse width of an output signal, the small processor incorporated in each pixel receives the output signal of the corresponding pixel and its neighbors and produces a binary coded output result for that specific pixel. The process is commenced in parallel among all pixels of the image sensor.

It is shown that using the proposed architecture, not only kernel convolution can be performed in the digital domain inside smart image sensors but also arbitrary kernel coefficients are obtainable simply by adjusting the sampling frequency at different phases of the processing.

Although in-pixel digital kernel convolution has been previously reported however with the presented approach no in-pixel analog to binary coded digital converter is required. Furthermore, arbitrary kernel coefficients and scaling can be deployed in the processing. The given architecture is a suitable choice for smart image sensors which are to be used in high-speed machine vision tasks.

By analyzing urbanism products, development plans and the process of modernization in Iran, the purpose of this paper is to critically trace the effect of dictatorial control on urbanism and the emergence of government-imposed urban segregation.

The main body of this work is concentrated on studying the history of urbanism in Iran, of which collecting data and descriptions played a crucial role. To prevent the limitations associated with singular methods, the methodology of this research is based on methodological triangulation (Denzin, 2017). With the triangulation scheme, the data are gathered by combining different qualitative and quantitative methods such as library, archival and media research, online resources, non-participatory observation and photography. For the empirical part, the city of Tehran is selected as the case study. Moreover, individual non-structured interviews with the locals were conducted to gain more insights regarding the housing projects.

The results reveal that despite the intense propaganda, the regime policies barely mentioned the urban poor. With the rise of new principles of architecture and urban planning, the regime tried to promote the image of an updated society; restructuring of the urban space was part of this process. However, the majority of the urban projects disregarded the financial ability of low-income groups and eventually benefited only the middle and upper classes. Also, by imposing a physical distance, low-income neighborhoods were located in the south in order to marginalize the urban poor who were in contrast with the idea of a modern city. Under these circumstances, severe economic inequality was provoked, which to this day has transformed into a complex socio-spatial segregation.

The works of general historical studies are not concentrated on urbanism and urban researchers have mostly focused on urbanism products during different periods, regardless, of the importance of urbanism as a tool in the service of hegemony. In other words, the majority of existing research investigates the evolution of urbanism and architecture in modern Iran, by questioning “what has been built?” and has ignored to trace the beneficiaries of the urban projects and to question “built for whom?”. Moreover, urbanism under the government of Mossadegh (1951–1953) has been largely overlooked, which could be due to his short time as Prime Minister of Iran. Mossadegh’s government was the first democratic government in Iran; hence investigating the policies used in this period has a great importance.

Insufficient physical activity leads to an increase in chronic diseases. Skills-based health education methods are supposed to be more successful than traditional methods to promote healthy behaviors. Skills-based health education is an approach to create healthy lifestyles and skills using participatory methods. The purpose of this paper is to examine the effects of skill-based education method on physical activities of female adolescents.

This was an experimental study on 80 female public high school students aged 12-14 years old in Tehran. The participants were randomly divided into two groups: experimental group of 40 girls who were educated using “Skills-based education method,” and control group of 40 girls who were educated by lecture as a routine educational method for health promotion. Data were collected using a valid and reliable questionnaire to assess physical activity-related knowledge, attitudes and behavior. Data were gathered three times; before, immediately after (Phase 1) and two months after educational intervention (Phase 2). Data analysis was performed using SPSS 20.

Intra-group comparison demonstrated that both educational methods can increase knowledge, attitude and behavior of the students after intervention comparing to before intervention (RMANOVA; p<0.05). However, the comparison between groups demonstrated a significant higher increase of knowledge (t-test; p<0.01 and p<0.0; phase 1 and 2, respectively), and behavior (t-test; p<0.01 and p=0.002; phase 1 and 2, respectively) but not attitude (p=0.083 and p=0.125, phase 1 and 2, respectively) among the students participated in the experimental “skilled based health education” group rather than the control “lecture” group.

Skill-based health education comparing to routine lecture-based education creates deep and long lasting knowledge and behavior and is highly recommended for promoting physical activity and other health-related knowledge and among adolescents.

Universities play a central role in scientific development and progress in societies, so, the need for supporting new businesses in universities becomes very important that science and technology park-based incubators can meet it. The purpose of this paper is to prioritize the factors influencing strategic management of university business incubators (UBIs).

Present research prioritizes the factors influencing strategic management of incubators using analytic network process (ANP). The authors gathered data from UBIs affiliated with science and technology park of Guilan, located in city of Rasht (Iran) using the ANP questionnaire during year 2017.

Factors influencing strategic management of incubators comprised of four main criteria and 14 sub-criteria. The criteria and sub-criteria were ranked based on their importance. Results show that “talented managers” has the highest importance for strategic management of UBIs.

This study offers a novel analysis and contribution to the knowledge of ranking UBIs with a multi-criteria decision-making technique. Results of this research show the relative importance of criteria and sub-criteria, which contributes to further improvement of incubator management. University managers and incubator directors can utilize the findings for better resource allocation and aligning the strategies of incubators with macro strategies of the country.

The main objective of this study is to evaluate the impact of Persian Scientific Papers (PSPs) on Persian Wikipedia by studying Wikipedia's citations to these papers.

The present study is applied research, which has been performed by the web-mining method, such as downloading web pages, extracting information (references), identifying papers, detecting peer-review journals and calculating the frequency rates. The statistical population included 10,000 Persian Wikipedia Pages (PWPs) that were analyzed in two rounds with a six-month interval.

The number of pages containing the Persian references section was 3,994 and 4,063 out of the 10,000 pages extracted in the first and second rounds. The ratio of pages that cited scientific sources (58 and 67 pages) to the pages extracted from the PWP was equal to 0.58 and 0.67%. The ratio of pages that cited scientific sources to pages with Persian references in each round was equal to 1.45 and 1.64%. The number of references extracted from the PWP in each round equaled 30,441 and 35,891. Eight titles from reputable Persian journals had received at least three citations from Wikipedia.

The present study has determined the extent of interaction between science and society (knowledge flow) in the form of citations from Wikipedia articles to articles in peer-reviewed journals. The study of this issue in Persian Wikipedia in more than 2000 Persian peer-reviewed journals shows the originality of the present paper. Studying citation reliability in a collaborative and openly editable platform is another originality of the work.
