Seismic Hazard Analysis (SHA) is carried out for the city of Islamabad using both deterministic and probabilistic approach. Earthquake catalogue compiled by National Engineering Services Pakistan (NESPAK) for the period of (1505-2006) has been used. All Quaternary faults in the vicinity of Islamabad have been considered for deterministic hazard analysis. Seismic zoning map of NESPAK has been utilized in the research. Earthquake catalogue contains total of 11,149 events. Earthquake events of moment magnitude (Mw>4.0) are taken for developing the recurrence relationships of selected four (04) seismic source zones. The attenuation equation of Boore and Atkinson 2008 next generation attenuation (BA08 NGA) has been used for the determination of the ground motion parameters. Maximum PGA of 0.49g by BA08 NGA obtained for Islamabad at rock site due to Main Boundary Thrust (MBT). In PSHA using the Crisis-2007 software, PGA values with 10% probability of exceedance in 50 years i.e. the return period of 475 years have been determined. The PGA results obtained at bedrock are 0.28g by BA08 NGA attenuation relation.

Pakistan lies in one of the most tectonically active regions of the world. The latest destructive 2005 Kashmir earthquake of magnitude 7.6 struck the northern part of Pakistan which caused death toll of about a hundred thousand people and monitory losses of about five billion US dollars. After this earthquake, most of research activities were directed to define earthquake hazard. However, amongst other problems in those studies, one hard decision is the use of attenuation relationship as no such equation is developed for Pakistan. These studies either do not consider the newly developed New Generation Attenuation (NGA) equations or use a single NGA equation. The purpose of this study is to utilize all NGA equations to define seismic hazard in terms of peak horizontal acceleration using Deterministic Seismic Hazard Analysis (DSHA) for a site near Tarbela Dam, Pakistan. The PGAs from all NGAs are weighted to get mean PGA for design. The site of interest, where previously recorded PGA was 0.16g for Kashmir 2005 earthquake-150 Km away from the epicenter, is surrounded by 8 faults. This site has a forty feet high slope inclined at 53° to the horizontal and made of dense gravels with a mixture of silt, clay, and sand. On top and bottom of the slope, boy’s hostels are being built. This necessitates seismic hazard analysis to be evaluated and a suit of acceleration time histories be selected for dynamic analysis of the slope. Three time histories are selected in this study from real earthquakes that matches parameters with the controlling earthquake.

Hydrological command of waterway system has been altering beneath the crash of mutually environment disparity and human actions in the overall milieu. With the advent of technology it is now possible to modelthe complete resource allocation of any hydrological network duly integrating both natural and artificial networks. Advance applications allow an excellent automated system to monitor, control and manage water allocations to better utilize water resources, minimize wastage and predict hazards. The first step to all of this is to have accurate information of the catchment areas, so that in coordination with concerned departments, modeling and predictions of futuristic results is possible which will yield better decision making leading to fructifying outcome. Physical hydrologic models for drainage areas are significant utensils to hold water assets management and foresee diverse hydrologic contacts and risks. Indus River is considered as salvation of Pakistan and it is also the largest river of the country. The approximate length of the river is 3180 kilometers and its drainage area exceeds 1165000 km 2 . Having in view the worth of Indus River and its socio economic implication on Pakistan it was planned to carry out research work on upstream of Terbela from Kachura. The intended approaches of this work were to generate empirical equations based on hydrologic model on a particular reach of the river i.e. from Kachura to Tarbela reservoir and by utilizing Geographic Information Systems and Remote Sensing means. Also the watershed analysis of the upstream of Indus river basin was performed, thus fashioning an essential tool for running and setting up of water resources for state.

This paper presents a new approach for evaluating the performance of single-input multiple-output (SIMO) cellular mobile communication systems in interference limited environment. The performance is analyzed by calculating the ergodic capacity and hence the spectral efficiency for Rayleigh fading SIMO channel in the presence of unequal power Rayleigh fading co-channel interferes. Expressions for evaluating system’s capacity using maximum ratio combining (MRC) are presented. The analytical results are verified by developing Monte Carlo simulations. Finally, the effect of variation in cellular parameters including cell size and re-use distance on the system’s performance is studied. It is shown that the employment of multiple antennas at the receiver can significantly improve the performance of the system. The capacity limits defined by MRC analysis are found within the estimated values of capacity using simulation. It is observed that increasing cell size and re-use distance decrease the effect of co-channel interference, however, the overall area spectral efficiency (ASE) of the system reduces due to the increase in cellular coverage area. Thus, a trade-off between capacity improvement and reduction in cell-size is suggested.

UASB reactors R-I and R-II each with an effective volume of 6.0liters were used to study the treatability of actual bleaching effluent obtained from NSSC pulp and paper mill at mesophilic temperature and neutral pH. Methanol as a source of an easily biodegradable substance along with an activated carbon of effective size 1.5-2.5mm was added to the reactor R-I to evaluate its efficiency. It was observed that corresponding to an OLR of 2.14kg-COD/m 3 -day the overall COD removal efficiency of the reactors R-I and R-II was 83% and 64%, respectively. And the AOX removal efficiency was noticed as 71% and 49% for reactor R-I and R-II, respectively. During the study it was observed that the treatability efficiency of reactor R-I was comparatively better but the amount of its biogas production was slightly lower. The average biogas gas production in reactors R-I and R-II during the course of study was observed as 0.19L/g-COD removed and 0.32L/g-COD removed , respectively, with mean methane composition of 58-60% in both the reactors. The results of this study suggest that the use of methanol and an activated carbon in a UASB reactor to biodegrade the bleaching effluent of NSSC pulp and paper mill at mesophilic temperature and neutral pH reactor is a feasible and viable technique.

In present research preliminary investigations like petrographic study, grain size evaluation and chemical analysis were undertaken on talc bearing rock of Swat emerald mines, aiming at finding some suitable processing technique to recover talc. A few processing tests using flotation, gravity separation and leaching methods were conducted to see the amenability of talc to enrichment by these techniques. Analysis of seven talcum powder products available in the local market including pharmaceutical grade talc was carried out for comparison with Swat raw- talc under study and to know the level of impurities in it. The results revealed that Swat emerald mines talc rock contains calcite, magnesite, dolomite, muscovite and quartz as impurities. Talc content in the original rock ranges from 60 to 65% and possible to liberate at grind size of 45 microns. Flotation test results revealed that talc upgraded to 85% with 80% recovery using frother as a process aid whereas, upgradation using gravity separation was 82%. The flotation concentrate on leaching further improved and the level of impurities reduced from15 to 8 %.

It has been a general perception that the hardness level of job-shop scheduling problems is comparatively high and that is why effective, efficient and accurate procedures for scheduling are required to substantiate its usefulness. Therefore, in this paper a hybrid approach, primarily based on Genetic Algorithm (GA), is presented to handle the problem of scheduling job-shop that consists of m number of machines and n number of jobs. This approach is actually a combination of a Local Search Heuristic (LSH) with standard GA and optimizes the value of makespan. Computational experience, that includes some case studies and a number of problems from literature, shows that the LSH has the tendency to minimize the makespan value and help the algorithm to find out the optimum solution for the problem in fewer generations.
