Abstract: 

In order to identify the Correlations and relationships between different traits in the bread wheat, 30 genotypes were investigated as sub-factors under the split plot experiment in the completely randomized design in greenhouse and the randomized complete block design in the field with three replications under the normal irrigation and post-anthesis water stress conditions. The results of the canonical Correlation analysis showed that at both normal and moisture stress levels, there was a significant Correlation between the pair of canonical variables obtained from the phenological traits and the yield components. Under the normal conditions in the greenhouse, to increase the spike density and length, the number of days to 50% flowering can be considered as a suitable selection criterion. According to the results of canonical Correlation analysis, under the stressed conditions in greenhouse, to increase the spike length, the number of days to the heading, maturity and 50% of flowering were among the important and effective factors. Under the optimum irrigation conditions in the field, the number of days to maturity was considered as one of the factors influencing the seed weight per spike. The results of canonical Correlation analysis under the field stress conditions showed that to increase the 1000-seed weight, the number of days to maturity can be considered an appropriate selection criterion.

Abstract: 

Purpose: The flourishing of political parties and currents is one of the signs of the degree of development in societies. In contemporary Iran and since the formation of the constitutional movement, political currents have gone through many ups and downs and it can be said that political currents in Iran after the Islamic Revolution have not yet reached the stage of institutionalization and stability. A characteristic feature of political currents in Iran is the divergence and division among political currents in recent decades, and this can be one of the reasons for the instability and cross-sectional and seasonal activity of political parties in Iran. Therefore, the necessity of leading research seeks to answer the question of how factors and divergence among political currents in Iran after the victory of the Islamic Revolution can be analyzed? And what are the scenarios for the advancement of political currents in Iran?Method: To answer this question, the method of causal-layer analysis, which is one of the qualitative methods in futures research, has been used.Findings: The research findings indicate that this divergence is due to a wide range of reasons from the level of causal systems (from the institutionalization of power to the formation of parties as elitist initiatives), worldview and discourse (from charismatic political authority to culture). Subsidiary-follower politics to myth-metaphor (Iranian individualism to belief in a strong state-weak society) can be analyzed.Conclusions: Three scenarios for the future of Iranian political currents can be considered: integration of currents as the security valve of the political system, the collapse of political currents in the traditional form, integration and consolidation in new social movements (virtualized parties).

Abstract: 

In order to assessment of relationship among grain yield and different traits and determination of the best indirect selection criteria for genetic improvement of grain yield in canola a randomized complete block design with three replications was conducted using 17 cultivars. Correlation coefficient analysis of grain yield showed positive and significant relationship between selected trait with traits days to shooting, days from planting to full flowering, plant height, number of grain/pod, 1000 grains weight, biological yield, harvest index, grain oil percent and oil yiel. Step-wise regression of grain yield as dependent variable and the other traits as independent variables revealed that 98.9% of variation exists in grain yield accounted for by the traits biological yield, harvest index, days to flowering initiation and number of grain/pod. Path analysis for grain yield based on traits that correlated positively and significantly with this trait designed high efficiency of traits 1000 seeds weight, biological yield, harvest index, days to shooting and number of grain/pod as indirect selection criteria for genetic improvement of this trait in canola cultivars especially in early generations of breeding programs.

Abstract: 

The use of lightweight and light weight block ciphers in the Internet of Things is inevitable. Recently, Midori64 has received a lot of attention among other lightweight ciphers due to its very low power consumption. Midori64 security has been threatened by various attacks, including side channel attacks. One of the types of side channel attacks is Correlation power analysis, in which an attacker can discover the encryption key by using the power leak of the cryptographic chip while the algorithm is running, data being processed and operations being executed. Masking against power analysis attacks is known as one of the most effective methods of cryptographic algorithms. The purpose of the mask is to disrupt the relationship between power consumption and ongoing operations. In this paper, an implemented version of the Midori64 code on an Atmega32 AVR micro-controller is attacked by Correlation power analysis, and an encryption key with 300 blocks of plain text is discovered. After masking the Midori64 with the Boolean masking method, the attack was performed again, and the experimental results showed that the Boolean masking method could prevent key discovery.

Abstract: 

Recognition and understanding the genetic control of traits, combining ability and genetic structure are directly related to the success of breeding programs. For this purpose, a 7 × 7 one-way diallel design was conducted in a randomized complete block design with three replications. The measured traits were included plant height, height to the first capsule, number of days to 50% and 90% of flowering, number of capsules per plant, number of seeds per capsule, number of days to physiological ripening, number of branches, leaves number and length, 1000-seeds weight, capsule weight, length and width, chlorophyll a, b and total chlorophyll, biological andeconomic yields, harvest index, oil and protein percentage. analysis of variance showed that there was a significant difference between genotypes and diallel analysis showed that the additive variance of all traits and dominant variance of all traits except height to the first fruit-bearing capsule were significant. The oltan cultivar was the best and Ardestan genotype was the worst genotype in terms of general combining ability. Sabzevar×TS-3 and Sirjan×Fars were the best hybrids in most traits. The general heritability was between 0.90 to 0.96 for biologic yield and number of branches, respectively and narrow heritability was between 0.36 to 0.91 for the number of branches and harvest index, respectively. The analysis of variance by Hayman method confirmed the results of Griffing analysis.

Abstract: 

اخیرا مفهوم گفتار قابل استفاده به عنوان راه حلی برای پردازش گفتار هم – کانال پیشنهاد شده است. در این مقاله، ابتدا الگوریتمی مبتنی بر تبدیل موچک گسسته (DTW) برای تشخیص خاصیت پریودیکی یک فریم از سیگنال هم – کانال پیشنهاد شده و در دو مورد از آن استفاده شده است. مورد اول برای بهبود عملکرد تشخیص قسمتهای صدادار و تعریف یک معیار جدید برای قابل استفاده بودن سیگنال گفتار هم – کانال و مورد دوم برای بدست آوردن یک سطح آستانه جدید و استخراج قسمتهای قابل استفاده از سیگنال گفتار هم – کانال. همچنین پارامتر P-Correlation به عنوان معیاری برای انتخاب دسته بندی کننده ای که fusion آن با الگوریتم پیشنهاد شده برای استخراج قمستهای قابل استفاده منجر به نتیجه بهتر می گردد معرفی شده است. پس از یافتن دسته بندی کننده مناسب، از یک الگوریتم fusion ساده و کارامد برای ترکیب نتایج تصمیم این دو دسته بندی کننده استفاده شده است. نتایج بدست آمده نشان می دهد که نسبت به الگوریتم های مشابه، الگوریتم پیشنهادی حدود 7 درصد دارای کارایی بهتری می باشد.
