SFN is a lightweight block cipher designed to be compact in hardware and efficient in software for constrained environment such as the Internet of Things (IoT) edge devices.Compared to the conventional block ciphers it uses both the SP network structure and Feistel network structure to encrypt.The SFN supports key lengths of 96 bits and its block length is 64 bits and includes 32 rounds. In this paper, we propose a deterministic related key distinguisher for 31 rounds of the SFN. we are able to use the proposed related key distinguisher to attack the SFN in the known-plaintext scenario with the time complexity of $2^{60.58}$ encryptions. The data and memory complexity of those attacks are negligible. In addition, we will extend it to a practical chosen-plaintext-ciphertext key recovery attack on full SFN (32 rounds) with the complexity of $2^{20}$. We also experimentally verified this attack.Also, in the single key mode, we present a meet in the middle attack against the full rounds block cipher for which the time complexity is $2^{80}$ the SFN calculations and the memory complexity is $2^{35.6}$ bytes. The data complexity of this attack is only two known plaintext and their corresponding ciphertext.

The human desire throughout history has always been to have a good quality of life, and on the other hand, the most important goal of urban development and management is to improve the quality of life and happiness of citizens; The purpose of this research is to investigate and evaluate the impact of urban management on the quality of life from the perspective of the citizens of Dezful city. The research method in this study is descriptive-analytical, which was used to collect information from library and field sources. The statistical population of the research consists of the citizens of Dezful city, based on the population of 2020 equal to 280,591 people; 400 of them were selected through the Lin and Demorgan table and stratified random sampling method. The tool for collecting information in this research is a researcher-made questionnaire, whose validity was confirmed in a formal way (validation by experts and specialists) and Cronbach's alpha reliability was confirmed as (0.834). The results and findings of the research from data analysis with the help of spss statistical software showed that there is a significant relationship between the performance of urban management and the quality of life of citizens at the rate of 0.359; Also, there is a significant relationship between urban management indicators (urban-physical (0.281), social-cultural (0.161), intra-organizational (0.232) and the quality of life of citizens of Dezful city. The results of the multivariate regression test also indicate that urban management indicators have been effective in improving the quality of life of the citizens of Dezful by 13.8%; Also, the findings of the research show that the average level of satisfaction with the intra-organizational index of urban management is relatively weak (2.281) from the point of view of the residents of Dezful city. The effect of socio-cultural index in improving the quality of life of citizens is reversed (-0.139) and on the other hand, the functional status of this index is equal to 2.512, which is considered an inappropriate situation.

Let $\mathbb{F}_{q}$ be a finite field with $q$ elements where $q = p^{m}$, and $R=\mathbb{F}_{q}+u \mathbb{F}_{q}$ denotes the ring $\frac{\mathbb{F}_{q}[u] }{\langle u^{2}\rangle}$. For positive integers $\alpha$ and $\beta$, a nonempty subset $C$ of $\mathbb{F}_{q}^{\alpha}\times R^{\beta}$ is called an $\mathbb{F}_{q}\mathbb{F}_{q}[u]$-additive code if $C$ is an $R$-submodule of $\mathbb{F}_{q}^{\alpha}\times R^{\beta}$. In this paper, we study these codes with respect to homogenous and Lee weights. Among main results, by the Gray image of these codes, we obtain $[q^{2}+q, 2, q^{2}]$ and $[2(q+1), 2, 2q]$ one weight optimal codes over $\mathbb{F}_{q}$.

Tehran metropolis does not have a specific, defined and formal system for managing the institutional capacity of urban management; But this system is managed and transmitted by relying on the structures, methods and common norms of urban and rural governance. The fragmentation and fragmentation of urban management in the city of Tehran due to the different institutions and organizations that originate from the city government model, the lack of capacity for inter-institutional and intra-institutional interaction can be seen as the result of the official dominance of the power institutions and the non-alignment of informal institutions with their policies and programs. The purpose of the research is to policy the key factors and variables affecting the institutional capacity of urban management. The research method, from the point of view of the goal, is of the type of applied-developmental research, in terms of the main research methods, it is in the category of descriptive-analytical research. Also, the type of data in the research is a survey, and the main tool used to collect data is interviews with managers, experts of Tehran municipality and university professors in the form of a questionnaire, which is a suitable narrative tool. The sampling method in this study was simple random sampling and the sample size was determined to be 100 people with a measurement error of ten percent. The findings of the research show that the strongest component of the desired institutional capacity is the readability and transparency of laws and regulations, with an average of 3.37, and the lowest average belongs to the component of inter-institutional capacity, which indicates the weakness of the institutional capacity in Tehran metropolis. The results show that the components of communication resources and the ability of institutions have a far greater contribution compared to other components in predicting the dependent variable, such that a unit change in the standard deviation of communication resources and the ability of institutions causes the standard deviation of the variable to increase. dependent (institutional capacity of urban management) to change by 28 and 18 percent. While a unit change in the standard deviation of participation only causes the standard deviation of the dependent variable to change by 2%.

Biometric systems are an important technique for user identification in today's world, which have been welcomed due to their non-invasive nature and high resistance to forgery and fraud. Physiological and behavioral biomarkers are two main types of biometric identifiers. Behavioral identifiers, such as voice recognition, are based on human or even animal actions. Physiological biometrics, such as fingerprints and facial recognition, which have been used in our daily lives in the past years, are based on the physical characteristics of the human body. One of the various biometrics that have been investigated in studies in this field is the heart signal, which has been well used in authentication and identification systems due to its simple acquisition process compared to biomarkers such as the brain signal. In addition, there are valid databases on heart signal data, which the researchers of this issue refer to evaluate their systems. In this study, the analysis, analysis, and comparison of different authentication methods using heart signal biometrics have been studied. Also, in the following, the advantages and disadvantages of deep learning methods and models proposed in this field have been examined. In the final part, firstly, the implementation of the method presented in Fuster and Lopez's research is discussed, and then, to evaluate, we present the tests designed using the network created in this study, and after that, concluding based on the results.

With the increasing and widespread application of deep learning and neural networks across various scientific domains and the notable successes achieved, deep neural networks were employed for differential cryptanalysis in 2019. This marked the initiation of growing interest in this research domain. While most existing works primarily focus on enhancing and deploying neural distinguishers, limited studies have delved into the intrinsic principles and learned characteristics of these neural distinguishers. In this study, our focus will be on analyzing block ciphers such as Speck, Simon, and Simeck using deep learning. We will explore and compare the factors and components that contribute to better performance. Additionally, by detailing attacks and comparing results, we aim to address the question of whether neural networks and deep learning can effectively serve as tools for block cipher cryptanalysis or not.

One of the strategies to reduce water losses in agriculture is proper irrigation scheduling, which is based on accurate estimation of crop water requirement. In order to determine the evapotranspiration rate of three rose varieties, a one-year study was conducted in a hydroponic greenhouse equipped with drip irrigation system in Arak Plain using drainage type lysimeters. Reference evapotranspiration was also determined using a drained micro-lysimeter with grass. The results showed that the total amount of reference evapotranspiration in the greenhouse was 1608 mm. Also, the total evapotranspiration value of Utopia rose during this growth period was 1423 mm, Dolcevita rose 1480 mm and White rose 1313 mm. The annual average of daily evapotranspiration of rose varieties was 3.8 mm/day. Due to rose bushes being perennial, the crop coefficients did not have four growth stages and, therefore, the average coefficients varied between 0.7 and 0.96 in 10-day intervals. The results also indicated that the average crop coefficient of rose varieties was 0.81 over a year and the average amount of applied irrigation water was 20573 m3.ha-1.year-1 for approximately 75000 rose plant /ha.

Use of environmentally friendly hydrogen (H2) as a clean fuel in massive scale requires safe and efficient storage and generation systems. Sodium borohydride (NaBH4) hydrolysis is one of suitable methods for Hydrogen production. However, requirement to expnsive noble metals catalysts limits its commercial usage. In this research, for development of cheap non-noble metal catalysts with high activity and stability, cupper- iron nano catalysts (Cu-Fe) with different mole ratios of (1:1), (3:1) and (1:3) were synthesized and their performane are compared with each other and with pure Cu. According to obtained results, Cu-Fe catalyst with 1:1 mole ratio has the largest specific surface area (170.4 m2/g) in comparision with other sysnthesized catalysts and pure Cu. Hydrogen generation over this catalyst is five times more than produced hydrogen over pure Cu. Then, effect of some stablizers such as Polyvinylpyrrolidone (PVP), tetradecyltrimethylammo- nium bromide (TTAB), sodium dodecyl benzene sulphonate (SDBS) and Triton X-100 on Cu:Fe (1:1) performanec are investigated. It was shown that produced hydrogen over Cu:Fe (1:1) stablized Triton-X-100 catalyst is 35% higher than Cu:Fe (1:1) catalyst without stabilizer. Also, the stability of this catalyst is significat and it maintains 70% of its original activity after five usage periods of NaBH4 hydrolysis. Ultimatley, Cu:Fe (1:1) stablized Triton-X-100 nano catalyst can be utilized as an active and stable catalyst for NaBH4 hydrolysis and H2 generation.

In this paper, we present some attacks on GAGE, InGAGE, and CiliPadi which are candidates of the first round of the NIST-LWC competition. GAGE and InGAGE are lightweight sponge based hash function and Authenticated Encryption with Associated Data (AEAD), respectively and support different sets of parameters. The length of hash, key, and tag are always 256, 128, and 128 bits, respectively. We show that the security bounds for some variants of its hash and AEAD are less than the designers' claims. For example, the designers' security claim of preimage attack for a hash function when the rate is 128 bits and the capacity is $256$ bits, is 2^{256}, however, we show that the security of preimage for this parameter set is 2^{128}. Also, the designer claimed security of confidentiality for an AEAD, when the rate is 8 bits and the capacity is 224 bits, is 2^{116}, however, we show the security of confidentiality for it is 2^{112$. We also investigate the structure of the permutation used in InGAGE and present an attack to recover the key for reduced rounds of a variant of InGAGE. In an instance of AEAD of InGAGE, when the rate is 8 bits and the capacity is 224 bits, we recover the key when the number of the composition of the main permutation with itself, i.e., r_{1}, is less than 8. We also show that CiliPadi is vulnerable to the length extension attack by presenting concrete examples of forged messages.

One of the most important factors in determining the depth of foundations in structures adjacent to the water flow is the scouring phenomenon; the scouring is a phenomenon caused by the interactions between water flow and erodible bed materials, which causes the removal of sediments where hydraulic structures are located, including bridge piers. Every year, a great number of bridges are damaged due to local scoring of their piers and foundations. In this paper, the geotechnical study of Malahide viaduct failure due to scouring was carried out using Plaxis 2D software. For this purpose, the Malahide viaduct, which was damaged in 2009 due to bed scouring of one of its piers, was selected and the necessary simulations were carried out based on the bridge specifications, and the conditions of the bridge underlying bed was investigated. Simulations results showed that the cause of scouring in the bed of collapsed pier was the high shear strains of the bed, bed shear strength parameters (i.e. angle of internal friction and cohesion) reduction and as a result, reducing the bed resistance to the scouring. It was also found that by using the micropile group below the foundation of bridge pier as a solution to reduce the scouring effect, the bed maximum scour depth is significantly reduced compared to the shallow foundations without micropiles; Also, by using the micropile group, the shallow foundation thickness can be reduced, provided that after foundation thickness reduction and micropiles application, the structure safety factor remains in the stable range.

Carbon monoxide mainly causing serious problems for environmental and catalyst systems.Oxidation of CO to CO2 is an effective way to reduce these problems. In this work, the graphene substrate was doped with different atoms targeting the CO oxidation. Third group atoms Boron B and Aluminum Al and fifth group atoms N were used for graphene dopping and the final catalysts were BN and AlN doped structures. The electronic structure and catalytic properties of binary BN, AL-doped graphene were investigated through density functional theory DFT. Results show that the AlN doped graphene strictly activates the oxygen reactivity compared to BN one. The activation energy of CO oxidation on AlN is done through Eley-Rideal mechanism as follows: CO O2 → CO2 Oads, the energy value is about 2.58 kcal mol-1. Also, the second oxidation step is occurred through the adsorption of oxygen on AlN doped graphene with no energy barrier. Thus, the substitution of a C-C bond with Al-N is an effective way to design the graphene based catalysts for CO oxidation.

Well-dispersed PtSn/C and PtSnO2/C catalysts with anatomic ratio of Pt:Sn (3:1) were deposited onto carbon using a modified alcohol-reduction process for electrochemical oxidation of ethanol. These materials were characterized using energy-dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD). An electrochemical study in theethanol and acid medium showed that the PtSnO2/C catalyst had a better performance compared with the PtSn/C and Pt/C catalysts. The CV analysis indicated that the presence of SnO2 increased the sensitivity of the catalyst to oxidation of acetaldehyde because of its low onset potential for the electrooxidation of adsorbed ethanol and acetaldehyde compared to PtSn/C and Pt/C. Since the activation of C-C bond breaking results in the generation of higher current density (mass activity) at higher potentials, the PtSnO2/C catalyst has been found favourable for the overall oxidation of ethanol.
