    Access to quality education
    (UMT.Lahore, 2015) Usman Ali
    In the current decade government of Pakistan in general and government of the Punjab education department in particular addressed the need for advancement in processes of education that needs promotion of education as an identity. The measures included various sort of diverse initiatives, the prominent being; Directorate of Staff Development (DSD), Punjab Education Foundation (PEF), Punjab Examination Commission, Chief Minister’s Education Reforms Roadmap, Punjab Education Sector Reforms Programme (PESRP), Punjab Educational Endowment Fund (PEEF) and Daanish Schools. It is customary that measures are undertaken but not monitored and followed up which causes chaos and panic ultimately leading to non fulfillment. The study under discussion is an endeavor addressing the “Access to quality education; Analysis of initiatives of Government of the Punjab”. The major objectives persuaded were to identify the initiatives of the government of the Punjab wherein the span of accomplishment lies within 2013-18. It aimed at studying the initial intents and their level of achievement. It further intends to explore the problems that came across by the different initiatives in their realization and to know the impact of undertaking initiatives on the quality of education in the province. It was a descriptive study spread over document analysis, interviews and focus group discussion. Interviews of individuals who worked in the decision making capacity are found well versed with the processes and initiatives undertaken in particular. The initiatives were discussed in isolatio n from others and procedure of description comprised of introduction, intents, infrastructure, initiatives, budget allocation, achievements and gaps in practices. The conclusions were drawn initiative wise and the major conclusion was that initiatives were partially undertaken and most of them remained unaccomplished. Chief Minister’s Education Reforms Roadmap is a vivid example which has been accepted by the government as a total failure and it has been advised to reinitiate the same by the experts. The recommendations have been made as the consolidated facts which are to be followed for all the initiatives. None of the initiatives were practicable; it is recommended that essential framework, finance and expertise be made available first and then the initiatives be launched. It is recommended that the initiatives already launched and partially matured, be fulfilled first before undertaking any new initiative and the man power from within the department be utilized for making the initiatives operational rather than entrusting it to the bureaucracy.

    Degree based topological invariants of operations on graphs.
    (UMT Lahore, 2021-08-05) Usman Ali
    Let H = (V (H), E(H)) be a graph with vertex set V (H) and edge set E(H) ⊆ V (H) ×V (H). A topological invariant (TI) is a function that associates a numeric value to the underlying graph. TIs are used to predict the physical and chemical properties of the graphs. These are also used in the study of quantitative structures activity relationships (QSAR) and quantitative structures property relationships (QSPR). Gutman and Trinajsti ́c (1972) defined the first degree as well as second degree (connection number) based TIs to calculate the total π-electrone energy of molecules. In the study of hydrocarbons, they also used connection number (number of vertices at distance two) based TI. Recently, connection number based Zagreb indices such as first Zagreb connection index, second Zagreb connection index and modified first Zagreb connection index are widely studied. As per the data provided by International Academy of Mathematical Chemistry, comparatively to the classical Zagreb indices, the chemical capability of the Zagreb connection indices (ZCIs) provides the better absolute values of the correlation coefficients for the thirteen physicochemical properties of octane isomers such as entropy, acentric factor, density, total surface area, molar volume, boiling point, heat capacity at temperature, heat capacity at pressure, enthalpy of vaporization, standard enthalpy of vaporization, enthalpy of formation, standard enthalpy of formation, and octanol water partition. In this thesis, we compute the general results in the form of exact formulae and upper bounds for the Zagreb connection indices/coindices of the resultant graphs which are obtained by applying operations of Cartesian, lexicographic, tensor, strong, corona, disjunction and symmetric difference. To illustrate the obtained results, connection based Zagreb indices are also computed for their chemical structures such as linear polyomino chains, carbon nanotubes, fence, closed fence, alkanes and cycloalkanes. Moreover, the connection based Zagreb indices and their modified version as modified second ZCI (ZC∗ 2 ) and modified third ZCI (ZC∗ 3 ) are also studied for the subdivision-related operations on graphs. Mainly, a comparison among the old/new ZIs of the subdivision-related operations for the particular classes of alkanes is performed. Finally, we conclude that ZC∗ 3 -descriptor has more variability than the other ZIs and it may be more considerable for further investigations of several chemical compounds.

    GSM monitoring and tap changing of a transformer
    (University of Management and Technology, 2015) Rashid Bashir; Usman Ali; Shahzad Khuram
    In our country Pakistan we are facing Electricity and Power Problems. Often there is Fluctuation of main supply that can damage our home appliances and other electrical Equipments. Also the overloading of transformers is normal problem and due to the Improper monitoring they can get damaged. This result in loss of supply of electricity and also loss of money spent on these transformers. Our aim is to cover both of these problems and somehow we have presented a Solution. Our project entitled “GSM monitoring and Tap changing of a Transformer”can Monitor remote transformers including their Voltage Current and Power. It can also Act as a stabilizer for the load and changes taps of transformer according to main Supply and load demand. Monitoring of transformer is done through GSM and is displayed on LCD. And we have used TRIAC for switching of Taps of transformer. Our thesis further elaborates this solution step by step. This implementation has a high start up cost but the maintenance cost is very moderate and acceptable. Our project also solves the problem of stealing of transformer which is a major issue Nowadays. We have installed an alarm to indicate the operator about the stealing of Transformer. Although this project can bring revolution in power transmission and generation System of Pakistan but still there is a room of improvement like installment of infrared sensor with transformers for security cooling and heating of transformers better monitoring transformers with a technology better than GSM as sometimes GSM signals can cause problem in hilly areasMonitoring of each individual load and much more. We have just presented a concept and taken a step towards improvement of monitoring of transformers and fulfilling load requirements. And afterwards we have practically implemented this concept to present a model. There can be much improvement in this as improvement is nature.

    Implementation of anti-islanding scheme for distributed generation system using over/Under voltage and frequency monitoring technique
    (University of Management and Technology, 2013) Usman Ali; Agha Arslan Khan; Zeeshan Ather
    In this project we have integrated Photovoltaic system with power grid. By interconnecting separate utilities with the high voltage (DG) system, it is possible to pool both generation and demand, not only providing a number of economic and other benefits, including a more efficient bulk transfer of power from generation to demand centers. The interconnected DG system, by linking together all participants across the transmission system, makes it is possible to select the cheapest generation available. Transmission circuits tend to be far more reliable than individual generating units, and enhanced security of supply is achieved because the transmission system is better able to exploit the diversity between individual generation sources and demand. An interconnected DG system enables surplus generation capacity in one area to be used to cover shortfalls elsewhere on the system, resulting in lower requirements for additional installed generation capacity, to provide sufficient generation security for the whole system. Without DG interconnection, each separate system would need to carry its own frequency response to meet demand variations, but with interconnection the net response requirement only needs to match the highest of the individual system requirements to cover for the largest potential loss of power (generation) rather than the sum of them all. Main idea is to work on Anti-Islanding Scheme in which we calculate voltage, frequency of both sides. If they lie in tolerable range then permission to close command is issued for respective circuit breaker. High performancePIC18F458 RISC CPU is used for processing the inputs. Sinusoidal signal from load end of system are converted to digital form and after full wave rectification these samples are used for calculation of voltage. To measure frequency input is given to the controller in the form of pulses and then pass it to ADC controller. Measuring phase angle was quite an interesting task and caused a lot of effort. Time difference between starting of two waves is used to compute phase angle.

    Smart DSM: a layered model for development of demand side management in smart grids
    (3rd International Workshop on Software Engineering Challenges for the Smart Grid, 2014) Fahad Javed; Usman Ali; Muhammad Nabeel; Qasim Khalid; Naveed Arshad; Jahangir Ikram
    Growing power demand and carbon emissions is motivating utility providers to introduce smart power systems. One of the most promising technology to deliver cheaper and smarter electricity is demand side management. A DSM solution controls the devices at user premises in order to achieve overall goals of lower cost for consumer and utility. To achieve this various technologies from deferent domains come in to play from power electronics to sensor networks to machine learning and distributed systems design. The eventual system is a large, distributed software system over a heterogeneous environment and systems. Whereas various algorithms to plan the DSM schedule have been proposed, no concerted effort has been made to propose models and architectures to develop such a complex software system. This lack of models provides for a haphazard landscape for researchers and practitioners leading to confused requirements and overlapping concerns of domains. This was observed by the authors in developing a DSM system for their lab and faculty housing. To this end in this paper we present a model to develop software systems to deliver DSM. In addition to the model, we present a road map of software engineering research to aid development of future DSM systems. This is based on our observations and insights of the developed DSM systems.
