آنکھ سے دور سہی دل کے قریں رہنے دے

آنکھ سے دُور سہی، دل کے قریں رہنے دے
میری ہر سانس میں تو خود کو مکیں رہنے دے

میں کہ اک عکس ہوں گمنام سا پس منظر ہوں
کب کہاں کیسے کسی طور کہیں رہنے دے

اک نظر مجھ پہ مرے ماہِ منیر ایسی ہو
کب طلب میں نے کیا زر یا نگیں، رہنے دے

میں ہوں اس قافلۂ عشق سے بچھڑا راہی
میرا کب ٹھور ٹھکانہ ہے کہیں، رہنے دے

تجھ سے منسوب ہوئی، تجھ سے ہی منسوب رہوں
غیر کے آگے جھکے گی یہ جبیں، رہنے دے

دل میں یا آنکھ میں یا دستِ حنائی میں فضاؔ
تیری مرضی ہے جہاں چاہے، وہیں رہنے دے

Development and Validation of Extended Multi-Dimensional Scale of Entrepreneurial Ecosystem in the Context of Pakistan

The purpose of this research is to validate the multi-dimensional scale of EntrepreneurialcEcosystem in the context of Pakistan. This research is based on 7 constructs with 54 items that affect the entrepreneurial ecosystem in any given region. The sample of 244 respondents are the owners of companies and, startups who participated in this research. The Confirmatory factory analysis showed factor loadings of all constructs greater than 0.40, while partial least square structural equation modeling showed acceptable values of construct reliability, composite reliability, however, average variance extracted was shown to be greater than 0.40 and less than the acceptable value of 0.5 for some constructs, while the HTMT ratio established discriminant validity of the constructs another criterion i.e. Fornell-Larcker criterion also established the discriminant validity of the constructs with some constructs having values less than 0.705, while some of the item outer loadings were found to be between 0.6-0.70 however, within the acceptable range. This research has validated the multi-dimensional scale of the entrepreneurial ecosystem with new sub-domain i.e. Support professions and support finance. This scale can be used to measure the strength of the entrepreneurial ecosystem of any region with appropriate homogeneous sample

Applications of Particle Swarm Optimization to Digital Communication

The whole class of evolutionary computing algorithms is inspired by the process of evolution in nature. Compared to the traditional optimization algorithms, a few striking features of these algorithms include their ability to address non-differentiable cost functions, robustness to the dynamically changing environment, and implementation on parallel machines. However, it was not until one and half decade ago, when these algorithms attracted researchers and got acknowledgement in terms of their application to the real world problems. The main reason behind this increased interest of the researchers owes to the ever increasing computing power. As a result evolutionary computing algorithms have been widely investigated and successfully applied for a number of problems belonging to diverse areas. In this dissertation the standard binary particle swarm optimization (PSO) and its soft version, namely soft PSO (SPSO) have been applied to four different problems of digital communication. Due to the exponentially growing computational complexity with the number of users in optimum maximum likelihood detector (OMLD), suboptimum techniques have received significant attention. We have proposed the SPSO for the multiuser detection (MUD) in synchronous as well as asynchronous multicarrier code division multiple access (MC- CDMA) systems. The performance of SPSO based MUD has been investigated to be near optimum, while its computational complexity is far less than OMLD. Particle swarm optimization (PSO) aided with radial basis functions (RBF) has been suggested to carry out multiuser detection (MUD) for synchronous direct sequence code division multiple access (DS-CDMA) systems. The MUD problem has been taken as a pattern classification problem and radial basis functions have been used due to their excellent performance for pattern classification. The two variants of PSO have also been used in a joint manner for the task of the channel and data estimation based on the maximum likelihood principle. The PSO algorithm works at two different levels. At the upper level the continuous PSO estimates the channel, while at the lower level, the soft PSO detects the data. The simulation results have proved to be better than that of joint Genetic algorithm and Viterbi algorithm (GAVA) approach.
