URBAN DEVELOPMENT PLANS OF RASHT (ANALYSIS AND REVIEW)

Abstract. About Six decades have passed since the preparation and implementation of the so-called comprehensive development plans in Iran and despite the fact that some positive results have been achieved; the desirable utility of experts and people has not been achieved. This article attempts to review urban development plans of Rasht by focusing on the second comprehensive plan of Rasht city as a case study and assesses the extent of realization of its objectives and its predictions. Specifically, the assessment of the results of the implementation of the second comprehensive plan of Rasht shows that there have been many mistakes in its projections and targets. Among them, the estimated population of Rasht in the comprehensive plan and its detailed plan was associated with 9.1% (46944people) and 6.02% (33654 people) of the estimated surplus. Also, in the area of expansion and communication network of the city, the second comprehensive and detailed plan of Rasht had 13% and 22.6% of mistakes (surplus to estimate). Regarding the area and per capita of urban utilities, about 20.28% of the area of use and 24.76% of per capita at the end of the plan implementation are surplus on prediction, and in other words, the forecast of the second comprehensive and detailed plan of Rasht in this area has been in short supply. Finally, the second comprehensive plan of Rasht, such as comprehensive plans of other cities, has weaknesses and inadequacies such as non-flexibility, conducting extra studies, extensive service descriptions, and emphasis on the framework that is due to the weakness ofthe nature of the comprehensive plan model more than anything else.Key words: comprehensive plan, detailed plan, Rasht city, assessment

Compound Multiple Access Channel with Confidential Messages

In this paper, we study the problem of secret communication over a Compound Multiple Access Channel (MAC). In this channel, we assume that one of the transmitted messages is confidential that is only decoded by its corresponding receiver and kept secret from the other receiver. For this proposed setting (compound MAC with confidential messages), we derive general inner and outer bounds on the secrecy capacity region. Also, as examples, we investigate 'Less noisy' and 'Gaussian' versions of this channel, and extend the results of the discrete memoryless version to these cases. Moreover, providing numerical examples for the Gaussian case, we illustrate the comparison between achievable rate regions of compound MAC and compound MAC with confidential messages.Comment: Accepted at IEEE ICC 2014. arXiv admin note: substantial text overlap with arXiv:1402.479

Medindo a satisfação dos moradores do município de Mehregan, em Mashhad, na perspectiva da habitação sustentável

Demographic developments in Mashhad and surrounding rural areas which are now considered urban break points It is well established that these areas have become centers of attraction for low-income immigrants who intend to migrate to Mashhad, as well as low-income urban strata that have previously lived in Mashhad. Since all four types of worn-out urban textures, including urban heritage, non-urban, marginal and rural urban textures, are the middle and lower decay habitats, "The 5000 unit project of Mehregan Town of Mashhad" has played an important role in the physical and functional organization of these tissues and responding to the needs of the poor. In view of the above, and several years after the project was inaugurated, the superstructure and infrastructure problems of the project are the subject of research in this research. The research method in this study was descriptive-analytical and applied. According to the number of households in the city that formed the statistical population of the study, and based on Cochran's formula, the sample population was 366 persons. Also, Delphi method has distributed 32 questionnaires to expert experts. Descriptive and inferential statistical analysis of completed questionnaires and experts has been done with the help of nonparametric and parametric statistical methods. The results of field surveys showed that the observed frequency of low-satisfaction residents was 222 and above all, so it is safe to say that 95% of respondents are not satisfied with their residence in Mehregan town. It is believed that the residential units constructed in Mehregan town of Mashhad have poor compliance with the standards and standards of sustainable housing.Desenvolvimentos demográficos em Mashhad e áreas rurais circunvizinhas que agora são consideradas pontos de ruptura urbana Está bem estabelecido que essas áreas se tornaram centros de atração para imigrantes de baixa renda que pretendem migrar para Mashhad, bem como estratos urbanos de baixa renda que anteriormente morava em Mashhad. Como todos os quatro tipos de texturas urbanas desgastadas, incluindo herança urbana, texturas urbanas não urbanas, marginais e rurais, são habitats de decadência média e baixa, "O projeto da unidade de 5000 unidades da cidade de Mehregan, Mashhad" desempenhou um papel importante. a organização física e funcional desses tecidos e a resposta às necessidades dos pobres. Tendo em vista o exposto, e vários anos após a inauguração do projeto, os problemas de superestrutura e infraestrutura do projeto são objeto de pesquisa nesta pesquisa. O método de pesquisa neste estudo foi descritivo-analítico e aplicado. De acordo com o número de domicílios da cidade que formaram a população estatística do estudo, e com base na fórmula de Cochran, a população da amostra era de 366 pessoas. Além disso, o método Delphi distribuiu 32 questionários para especialistas. A análise estatística descritiva e inferencial dos questionários e especialistas preenchidos foi realizada com a ajuda de métodos estatísticos não paramétricos e paramétricos. Os resultados de pesquisas de campo mostraram que a frequência observada de residentes de baixa satisfação era 222 e, acima de tudo, portanto, é seguro dizer que 95% dos entrevistados não estão satisfeitos com sua residência na cidade de Mehregan. Acredita-se que as unidades residenciais construídas na cidade de Mashhad, em Mehregan, não cumpram com os padrões e padrões de habitação sustentável

Desynchronization Attack on RAPP Ultralightweight Authentication Protocol

RAPP (RFID Authentication Protocol with Permutation) is a recently proposed efficient ultralightweight authentication protocol. The operation used in this protocol is totally different from the other existing ultralightweight protocols due to the use of new introduced data dependent permutations and avoidances of modular arithmetic operations and biased logical operations such as AND and OR. The designers of RAPP claimed that this protocol resists against desynchronization attacks since the last messages of the protocol is sent by the reader and not by the tag. This letter challenges this assumption and shows that RAPP is vulnerable against desynchronization attack. This attack has a remarkable probability of success and is effective whether Hamming weight-based or modular-based rotations are used by the protocol

Analysis and Improvement of the securing RFID systems conforming to EPC Class 1 Generation 2 standard

Radio Frequency IDentification (RFID) technology is a wireless identification method in which security and privacy are important parameters for public acceptance and widespread use. In order to thwart such security and privacy problems, a wide variety of authentication protocols have been proposed in the literature. In 2010, Yeh et al’s proposed a new RFID authentication protocol conforming to EPC Class 1 Generation 2 standard. They claimed that this protocol is secure against DoS attack, replay attack, DATA forgery attack, and provides untraceability and forward secrecy. In 2012, Yoon showed that this protocol does not provide forward secrecy and DATA integrity. He improved the protocol and tried to eliminate the weaknesses and claimd that the improved protocol does not have the weaknesses of the primary protocol. In this paper, we show that the improved protocol has some weaknesses including DoS attack, back-end server impersonation, tag impersonation and DATA forgery attack. We also show that it can not provide forward secrecy of the reader and untraceability. We improve the protocol, which offers a high level of security and provides mutual authentication, untraceability and forward secrecy as well as resistance to DATA forgery, replay and DoS attacks, while retaining a competitive communication cost

The effect of descriptive evaluation of elementary school third grade subjects on academic achievement of students

The goal of this research was the effect of descriptive evaluation of elementary school third grade subjects on academic achievement of students and its comparison with traditional evaluation. The statistical population of the research included all female third grade students of elementary schools in ZarrinShahr in academic year of 2012-2013 who were a total number of 742 students as well as the elementary school third grade teachers who were a number of 34 teachers. Among them a number of 147 students and 28 teachers were selected via cluster sampling. Research methodology in this study was of survey-descriptive type. The research tools were checklists and a questionnaire of opinion toll, made by the researcher. To assess the validity of the tools used, the face validity and content validity were used and the validity of the questionnaire was estimated as a=0.93. Chi square test was used to analyze the research questions. The results of the research showed that using different methods of descriptive evaluation has been effective in improving the students’ performances in such subjects as the Holy Quran, social sciences, arts, science & Persian, while it has not been effective in improving their performances in such subjects as heavenly gifts (the Holy Quran for elementary students) and mathematics. Finally, the results of opinion toll showed that the teachers found descriptive evaluation more suitable than traditional evaluation in evaluating all the third grade subjects of elementary school. Keywords: Evaluation, Descriptive evaluation, Traditional evaluation, Students’ performances

Investigating the Efficacy of Sumac Topical Solution Against Permethrin-resistant Human Head Lice

Background: The present study aimed at determining the efficacy of applying Rhus coriaria (Sumac) solution for the treatment of Permethrin-resistant head louse in patients, who used permethrin for at least 2 consecutive periods, but have not been cured.Methods: This study is a before-after clinical trial performed on 100 patients with pediculosis aged between 2 and 50 years old and both sexes. All patients had used Permethrin at least twice consecutively (with at least 14 days interval) according to correct instructions (on the first and 7th day), but they have not been cured. Each patient received 60ml of Rhus coriaria solution for 3 consecutive days, and the treatment was repeated again for another 3 days; then, the patients were followed-up on the 4th, 10th, and14th days after the treatment.Results: The results showed a significant difference in the severity of head lice infection and itching before the treatment and 14 days after the treatment (P<0.001).Conclusion: Rhus coriaria solution was more effective in eliminating head-louse infestations on 4, 10, and 14 days after the treatment and itching disappeared in most of the patients, while negligible complications were observed
