Metaheuristics is a research area that delivers general purpose high quality optimization algorithms, proved effectual in dealing with complex global optimization problems. Success of metaheuristics greatly depends on their aptitude to establish equilibrium between their essential characters: exploration and exploitation. But the advent of No Free Lunch theorems by Wolpert and Macready established a general opinion that all algorithms perform equally when averaged over the whole function space and hence none of them can be claimed to be the best over the entire function space. For this reason, the basic algorithms require essential refinements and enhancements. The main goal of this thesis is twofold: to develop new effective hybrid metaheuristic strategies for solving selected global optimization problems and to analyze the performances of developed hybrid metaheuristics on mathematical benchmark functions and complex real world problems that can be modeled as global optimization problems. Generally, hybridization is carried out by integrating powerful components of different algorithms. The first hybrid metaheuristic proposed in this work is Controlled Showering Optimization (CSO) algorithm which is a combination of Artificial Showering Algorithm and frame based search mechanism. The second proposed hybrid algorithm is Cooperative Multi-Simplex algorithm (CMSA) that is based on collaborative search of multiple simplexes working under the iterations of a Non- Stagnated Nelder-Mead Simplex algorithm (NS-NMSA). The evolvement of the provably convergent variant NS-NMSA is also carried out in this work by identifying and coping the failures and stagnations of standard Nelder-Mead simplex algorithm. Multi-Simplex Imperialist Competitive Algorithm (MS-ICA) is the third hybrid metaheuristic which is designed by embedding NS-NMSA iterations in Imperialist Competitive Algorithm. The fourth hybrid metaheuristic designed in this continuation is obtained by integrating CMSA and Differential Evolution (DE) algorithm. In a specifically constructed computational framework, this hybrid algorithm in collaboration with Padé approximation is named as hybrid Evolutionary Padé Approximation (EPA) scheme. The efficiencies of developed hybrid metaheuristics are validated empirically along with some theoretical results. Statistical analysis of simulation results of CSO applications to diversified small as well as large scale benchmark functions is conducted for evaluating its computational efficiency and consistency. The posterior non-parametric statistical analyses of the results indicate significantly better performance of CSO algorithm. Theoretical convergence results of NS-NMSA are also accompanied by numerical simulations on reported counter examples and a test suite of 24 benchmark functions. The two proposed hybrid algorithms, CMSA and MS-ICA, are applied to solve physical nonlinear systems of equations and excellent results are observed. Finally the proposed EPA framework is implemented for numerical treatments of the nonlinear model of virus propagation in computer networks and the model of Dengue fever with incubation period of virus. Numerical simulations and residuals based error analysis confirm the abilities of the proposed hybrid EPA scheme to preserve the essential characteristics of the epidemiological models.

بنیادی انسانی حقوق کا اسلام اور اقوام متحدہ کے عالمی منشور کی روشنی میں تقابلی جائزہ

It has been the norm of the West that they allay the blessings and reforms brought into the world towards themselves as if the rest of the World was drenched into darknessof ignorance. The concept of Human Rights has laso been allayed to the British Magna Carta, though Islam has offered the most complete and comprehensive Human rights foundation hundred years earlier, aboout 600 years prior to Magna Carta. This research article pertains to a comparative study of the charter of Human Rights by UNO  and the comprehensive socio-political and economic sphere of Human Rights by Islam.

Molecular Investigation for the Role of Coat Protein in Transmission of Two Different Geminiviruses

The Chickpea chlorotic dwarf viruses (CpCDV) are members of the proposed genus Mastrevirus of the family Geminiviridae. They are single-stranded DNA viruses transmitted by the leafhopper Orosius albicinctus Distant. This virus is notorious to cause chickpea stunt disease in chickpea. Chickpea is the major developed host of CpCDV. It is a winter/spring season trim, though cotton is developed amid the mid-year months with little, assuming any, cover between the two. In the field, the infection has just been distinguished in chickpea, lentil, sugar and beans. Cotton leaf curl disease (CLCuD) is a serious disorder of several plant species that belong to the family Malvaceae, the most important of which is cotton. CLCuD is caused by infections caused by viruses belong to the genus Begomovirus (family Geminiviridae) exclusively transmitted by the whitefly Bemisia tabaci Gennadius. which is the absolute most critical biotic requirement to cotton creation crosswise over Pakistan and northwestern India. A distinctive strain of CpCDV recognized in cotton plants, co-infected with Cotton leaf curl Burewala virus (CLCuBuV). Co-infection is additionally an essential for recombination happening amongst infections, and the accessible confirmation proposes that the present ordered structure of the family Geminiviridae has come about because of intergeneric recombination. Geminiviruses are transmitted in a circulative persisted and non-propagative manner and do not replicate in their insect vector. The capsids of all the whitefly transmitted geminivirus have at least one antigenic epitopes in like manner, and it has been proposed that those might be determinants of vector specificity, which would demonstrate that the coat protein (CP) assumes a prime part in infection transmission. Very few experiments have been performed so far to study the co-infection of a begomovirus together with a dicot infecting mastrevirus (CpCDV), infecting the same host plants i.e., Xanthium strumarium L. (weed), cotton and squash (dicot plants). In the coinfection of mastrevirus with begomovirus, mastrevirus not only expanded its host range but also has amplified individually from host plant. However, at that time it was still unclear whether the leafhopper transmits the CpCDV to new host plant or the whitefly did this job due to transencapsidation. Hence to explore this aforementioned aspect this study was designed to replace CP gene of CpCDV (Genus: Mastrevirus, xv Family: Geminiviridae) with the CP gene of Cotton leaf curl Burewala virus (CLCuBuV; Genus: Begomovirus, Family: Geminiviridae). Polymerase chain reaction (PCR) amplification of whole genome of CpCDV (except CP region by using primers in opposite orientation) and CP gene of CLCuBuV was done. Ligate these two PCR amplified fragments in order to construct mastrebegomo chimeric virus. Infectivity assay was done by agroinfiltration of infectious clones of CpCDV, CLCuBuV+Cotton leaf curl Multan betasatellite (CLCuMβ) and mastrebegomo chimeric virus into tobacco (Nicotiana benthamiana Domin.) and tomato (Solanum lycopersicum L.). The entire infectious clones alone and in combination were successfully transmitted and replicated inside the host plants and produce characteristics symptoms in tobacco and tomato leaves. However the plants infected with combination of CpCDV and CLCuBuV+ CLCuMβ showed more severe symptoms than others. Virus acquisition and transmission experiments were done using screen cages in an insectary. For this purpose aviruliferous whiteflies were used which first acquired the viruses during 48-72 hours from the agroinfiltered plants and then liberated to healthy tobacco and tomato plants for transmission for the period of one month. It was evident from the results that the B. tabaci unable to acquire and transmit CpCDV and mastrebegomo chimeric virus and the plants showed no symptoms of infection. Although whitefly successfully acquired and transmitted the begomovirus whose presence later confirmed by DNA extraction from whiteflies and symptomatic plants followed by PCR amplification of CP gene and full length genome of viruses for authentication of results. So it has been confirmed that whiteflies are not responsible for transmission of CpCDV and mastrebegomo chimeric virus from diseased plants to healthy one. Full-length sequences of dicot infecting mastreviruses and monocot infecting mastreviruses were obtained from GenBank and their sequence names were cross verified according to the new International Committee on Taxonomy of Viruses (ICTV) Master Species List 2016v1.3. For phylogenetic investigation, groupings were first adjusted in MEGA6 programming utilizing MUSCLE. For deciding the percent nucleotide identity, viral sequences were adjusted by MUSCLE in the sequence demarcation tool (SDT) program. The Recombination detection program (RDP-4) was utilized to recognize likely parents and the degree of recombination in dicot and xvi monocot contaminating mastreviruses. The interaction of CP of mastrebegomo chimeric virus protein with whitefly inhabiting endosymbiotic GroEL protein was determined by using several proteomics tools. The three dimentional models of both proteins were designed by using Iterative Threading ASSEmbly Refinement (ITASSER) server and their stereochemical properties were determined by drawing ramachandaran plots. Physiochemical properties and hydropathy plot of mastrebegomo chimeric virus protein and GroEL protein was determined by using ProtScale while ProptParam tool was used to calculate the several chemical and physical parameters of the both proteins. Finally The Z-DOCK server was used which is well-known for protein-protein docking that runs top 10 predicates in the form of protein data bank (PDB) files. More or less it can be inferred that substitution of CP gene may expand our comprehension about the range and circulation of mastreviruses crosswise over world and will give the important data with respect to their control. Co-infection open ways to discover the potential variables, which made the mastreviruses to advance from monocotyledonous plants to dicotyledonous and their capacity to cause infection in non-host plants, along these lines extending its host run with the progression of time.
