Software product lines (SPL) engineering is an efficient means to enhance software quality, support requirement reuse and develop variants of products. Functional and nonfunctional features can be extracted from SRS docs of ancestry built artifacts to aid RR. In this paper we offer a recommendation web tool (prototype) to extract functional features and calculating reusability for amount of data available in the form of SRS of already developed systems. In initial-level, SRS docs are feed into system. System accesses natural language requirements automatically from SRS. Terms extraction is performed which depends on keyword occurrences from several combinations of nouns, verbs, and/or adjectives. Phrases that reflect functional features reside on SRS docs were extracted by using information retrieval (IR). FRs are then stored in knowledgebase automatically. In Secondary-level, requirement analyst inputs summary of prospective system and selects the operation to perform i.e. simple and advance search. System applies POS-tagger technique on software summary for tokenization to search functional features. These tokens are then passed to inference engine to match between knowledgebase to identify which features could be recommended to analyst to aid RR. Matched features with queried features are prioritized using collaborative filtering to assist requirement analyst in making right decision in different software engineering tasks, starting from forming the teams and specifying the requirements to subsequent projects.

The PV (Photovoltaic) cells have a non-linear current-voltage (I-V) and power-voltage (P-V) characteristics with a unique maximum power point (MPP), which entirely depends on the environmental conditions. So, to continuously extract maximum power from a PV system under varying environmental conditions, the maximum power point tracking (MPPT) control approach is needed to operate the PV system at MPP. Therefore, in this article, a non-linear hybrid robust integral backstepping MPPT control approach is proposed for stand-alone PV system. The system consists of PV array, noninverted DC-DC buck-boost converter and a resistive load. The resistive load is interfaced to PV array through the buck-boost converter. The designed MPPT control approach continuously adjust the duty cycle of the converter, in such a way that the PV array output voltage tracks the reference voltage, thus ensuring the maximum power extraction. The performance of the designed MPPT approach is tested and validated in MATLAB/Simulink under fast varying environmental conditions, varying load, faults and parametric uncertainties occurs in the PV system. The proposed control approach presents a zero overshoot, fast convergence, good transient response, less rising time, a minimum tracking error and a very fast reaction against environmental conditions. To show the superiority and robustness of the proposed MPPT control approach a comparative analysis is presented with the backstepping and PID control approaches.

Protection of micro-Grid is a future challenging issue. A fault occur at one part of micro-grid can cause the whole micro-Grid to be faulty. A protection scheme is needed which protect the micro-Grid by isolating that faulty part. Fault levels at both current and voltage parameters are different in stand-alone and utility grid connected mode. An effective protection scheme is developed for both modes in this paper. Fault levels at both current and voltage are analysed. After clearance of fault, reconnection of faulty part is also another major problem which needs to be sorted out. A reconnection scheme is also be presented in this paper. These effective protection and reconnection developed schemes are tested on system model for both utility grid connected and stand-alone mode of microgrid which are proven to be effective.

This paper shows the theoretical and numerical framework for basic and regenerative organic Rankine cycles. Exergetic analyses of basic and regenerative organic Rankine cycles at various evaporator pressure (EVP) with various working fluids are conducted in order to convert low-grade heat sources waste energy to useful work. The fluids selected for this analysis are R113, R123, R236ea, R245fa, and R141b. The results show that the regenerative organic Rankine cycle (RORC) gives better energy efficiency, exergy efficiency, network output, and the lowest total system exergy loss. R113 is the optimum working fluid for RORC at EVP of 2MPa to 3MPa. It is also concluded based on results by increasing the EVP the energy efficiency, exergy efficiency, network output increases, and total system exergy loss decrease

a number of issues regarding Land Record Management has been pointed out in the literature. In particular, developing countries like Pakistan face severe Land Record Management issues, such as data tempering with land record, provision of no means to fetch out a complete history of property ownership, working of various related Land Record Management System in isolation, etc. Prevalent traditional Land Record Management Solutions do not address such issues. To address these issues, we propose a Blockchain-based Land Record Management solution for Pakistan. The proposed system has been designed and implemented, details of which are presented in the paper.

Generating effective communication links in an offshore environment is a vital need for the oil and gas industry as well as the military domain. The highly conductive medium of the environment is yet the biggest hurdle to develop the channel. Focusing towards the challenges lies in underwater communication channel, this paper first presents an efficient transmitter and receiver design using the conduction current method. Subsequent to the design development, a comparative analysis is presented that can be used to model an optimum underwater communication channel through electromagnetic conduction. Effect of different channel characterization parameters is discussed such as conductivity, frequency and transmitter and receiver antenna separation. Through an efficient circuit design for transmitter and receiver, increasing frequencies increased the signal strength is proved. Further statistical analysis revealed that in the developed experimental setup, 100 kHz has a greater possibility in designing an efficient demodulation circuit design. The promising results have proved the possibilities in way forward for the technology.

Manufacturing cost of Double Sided Linear Permanent Magnet Flux Switching Machine (DSLPMFSM) suitable for long stroke applications can be reduced by optimizing secondary (stator) of the machine. In this paper, stator pole study of novel DSLPMFSM with mover slots and stator poles ratio of Ns⁄Np = 12⁄10, 12⁄14,12⁄34,and12⁄38 is done. Based on 2D Finite Element (FE) Analysis results, DSLPMFSM with Ns⁄Np = 12⁄14 is selected due to high flux linkage, and high thrust force. Initial design of 12/14 DSLPMFSM suffers with significant detent force and degrade machine performance by introducing periodic thrust force ripples. Asynchronous distribution of stator tooth (ADST) technique is utilized and detent force problem is effectively rectified. Furthermore, stator of 12/14 DSLPMFSM is optimized by deterministic optimization approach by defining variables for tooth width, shape, and height. Finally, two types of grooves (triangular and rectangular) are introduced, and optimized to decrease stator volume and thrust force ripples. Introduction of ADST technique and two fold optimization increased average thrust force up to 103.25% as compared to initial design, while thrust force ripple ratio is reduced from 52% to 25%.

Vehicular networks are constructed for efficient and secure data flow to make intelligent transportation system. It works by using central storage system which is inefficient as large amount of data is difficult to handle and also becomes the target of malicious activity. The flow of sensitive data on wireless channels for communication of vehicles with other nodes can also be chosen by attackers for attack. These challenges are tackled using blockchain solutions. The blockchain, a farfetched decentralized technology which is undoubtedly going to change overall trends of entire business and professional networking environment in the world to release the burden of centralization on the organizations even on the individuals and several developed countries have started to adopt this trend. This technology would be as dynamic, vibrant, efficient and secure as the category of consensus algorithms is used for the agreement and decision of joining the new block among network nodes. Security and efficiency of vehicular network is maintained through consortium blockchain boasting with Practical Byzantine Fault tolerance (PBFT) algorithm.
