المبحث الثاني: مأساۃ الحياۃ وأغنية للإنسان

المبحث الثاني: مأساۃ الحياۃ وأغنية للإنسان
"مطولة شعرية"
تکتب الشاعرۃ العراقیۃ المشھورۃ " نازك الملائکۃ" في دیوانھا المعروف "دیوان نازک الملائکۃ" أنھا تشرح الظروف الزمنیۃ والنفسیۃ والفکریۃ التي مرت بھا خلال کتابۃ مطولتھا الشعریۃ ’’مأساۃ الحیاۃ وأغنیۃ للإنسان‘‘ عبر عشرین عاماً من سنۃ 1945م إلی 1965م، وتقول : ’’یضم الأثر الشعري الذی أضعہ بین یدي القاریء في ھذا الکتاب ثلاث صور شعریۃ لقصیدۃ واحدۃ أولھا قد نظم بین سنۃ 1945م و 1946م وثانیھا قد نظم سنۃ 1950م وثالثھا متأخر التاریخ حتی 1965م، ویمکن أن تعد کل قصیدۃ من ھذہ القصائد الطویلۃ مستقلۃ عن الأخریین، لو لا أنني قد نسخت بعض الأبیات أحیاناً فنقلتھا من قصیدۃ إلی أخری علی اعتبار أنھا ما زالت ترضي ذوقي رغم مرور السنین‘‘۔
وتقول إنھا نظمت القصیدۃ الأولی عام 1945م وکان عمرھا إذ ذاک اثنین وعشرین عاماً۔ وعندما بدأت في نظم ھذہ المطولۃ فإن دیوانھا الأول (عاشقۃ اللیل) لم یظھر إلی الوجود بعد۔ وأنھا کانت تکثر من قراء ۃ الشعر الإنکلیزي فأعجبت بالمطولات الشعریۃ التي نظمھا الشعراء وأرادت أن یکون في الوطن العربي مطولات مثلھم، فبدأت في نظم القصیدۃ وسمتھا "مأساۃ الحیاۃ" وھذہ القصیدۃ دلیل علی تشاؤمھا المطلق، وأنھا کانت تشعر بأن الحیاۃ کلھا ألم وإبھام وتعقید۔ وتقول: ’’وقد اتخذت للقصیدۃ شعاراً یکشف عن فلسفتي فیھا ھو ھذہ الکلمات للفیلسوف الألماني المتشائم ’’شوبنھاور‘‘: "لست أدري لما ذا نرفع الستار عن حیاۃ جدیدۃ کلما أسدل علی ھزیمۃ وموت۔ لست أدري لماذا نخدع أنفسنا بھذہ الزوبعۃ التي تثور حول لا شيء؟ حتّام نصبر علی ھذا الألم الذي لا ینتھي؟ متی نتدرع بالشجاعۃ الکافیۃ فنعترف بأن حب الحیاۃ أکذوبۃ وأن أعظم نعیم للناس جمیعاً ھو الموت؟"۔
یتضح من ذلک أن الشاعرۃ کانت متشائمۃ مثل الشاعر الانکلیزي شوبنھاور وربما تشاؤمھا یفوق تشاؤم شوبنھا ور لأنھا ھي بنفسھا تعترف بھذا الشيء فتقول:’’والواقع أن تشاؤمي قد فاق تشاؤم شوبنھاور نفسہ، لأنہ۔ کما یبدو۔کان یعتقد أن الموت نعیم لأنہ...

مسئلہ حجاب: فرانسیسی مسلمان خواتین اور اسلامی تعلیمات

Human history is replete with preposterous and unjustifiable incidents of unearned sufferings against the women. Sometimes they were maltreated and molested harshly and sometimes they were abused, persecuted bestially. Contrary to these incidents occasionally they were considered superior and super angelic but on the contrary Islam has bestowed a dignified status to them regarding their rights and responsibilities. In this regard a comprehensive manifestation has been introduced by the Islam and until this manifestation was being followed by the Muslims no single complain was lodged by any woman against the violation of her basic in the Islamic societies till the climax of Islamic regime. But today some European countries are holding discussions to impose illegal sanctions against the veil of women and girls. The parliament of France has approved a discriminatory law against veil of the Muslim women or girls. It is amazing that Christian nun is at her liberty to cover her head with scarf or not but if Muslim women consider themselves safe in veil they are contemptuously scorned with derision and disdained. In this article views of France and Islamic teachings have been brought under discussion.

Sensor Array Assisted Spectrum Sensing and Performance Optimization in Cognitive Radio Networks

Cognitive Radio has gained worldwide attention from research communities and is expected to be a revolutionary technology for the next generation (4G) wireless systems. In this dissertation, Amplify-and-Forward (AF) based relay-assisted cognitive radio networks (RCRNs) are studied in an underlay spectrum sharing environment. The primary issue faced by underlay networks is the limited transmit power ability of the secondary users (SUs) due to the interference constraints towards the primary users (PUs), which reduces secondary throughput and allows only short- range communication. Thus, performance enhancement of secondary communication in the frequency bands allocated to the PUs is a major design challenge faced by the underlay RCRNs. It requires relay selection along with the fine tuning and adjustment of the transmit power of the secondary relays. In this thesis, we proposed advanced multiple relay selection schemes for secondary network in the Rayleigh flat-fading scenario considering the availability of perfect instantaneous channel state information (CSI). The effects of variations in the instantaneous CSI, transmit power of source and relays, interference threshold of the primary network, signal-to-noise ratio (SNR) threshold of the secondary network and size of potential relay network on multiple relay selection in underlay RCRNs are the main issues that are analyzed in depth in this research. Furthermore, the performance analysis of multiple relay selection has been carried out and closed form expressions for the outage probability and average probability of error have been derived through the cumulative distributive function (CDF) of the received SNR at secondary destination, which is a new contribution to the AF-based underlay RCRNs. The optimization tool used in this study is Artificial Bee Colony (ABC) global optimizer. Another novel idea proposed in this dissertation is Fuzzy Rule Based System (FRBS) for multiple relay selection and transmit power allocation (RSTPA), which is a new contribution to the underlay RCRNs. The proposed FRBS assisted RSTPA schemes aim to perform intelligent multiple relay selection for performance enhancement of secondary communication in power constrained RCRNs. It is proved through simulations that FRBS is an optimal choice to solve the non-linear optimization problems of SNR maximization and transmit power minimization. Another contribution of this research is in the field of spectrum sensing in CRNs. Spectrum sensing faces a lot of challenges in terms of reliability and accuracy of information for detection and estimation of primary transmissions in CRNs. The advantages and limitations of different cooperative and non-cooperative spectrum sensing schemes have been studied in detail, and a novel spectrum sensing scheme based on uniform linear array (ULA) of sensors is proposed, which not only detects the number of sources, but also estimates their parameters such as frequency, Direction-of-Arrival (DOA) and power strength. The effectiveness and reliability of the proposed scheme is proved under low SNR conditions. Genetic Algorithm (GA) hybridized with Pattern Search (PS) is used to optimize the results. All the proposed algorithms have been investigated through simulations under different design requirements, constraints and a well-defined range of different parameters to validate their significance and effectiveness.
