Title: ROBUST KINEMATIC SKELETON OF HUMAN 3D MODEL IN VIEWING STRAIGHT LIMBS Authors: Razzaq, A.; Moughal, T.A.; Zia, M.A.; Qadri, S.; Muhammad, S.S. Abstract: In 3D character animation, the creation of the skeleton is still long-winded task and relies on various manual modifications. In this paper, a novel approach is proposed to generate a kinematic skeleton for 3D human geometric model. More specifically, our concentration to create the plausible skeleton, which locates the precise position of the knee and elbow joints of the models that possessing straight limbs. Since inaccurate identification of the joints in skeleton extraction effected the quality of the character animation. Firstly, in the proposed approach, approximate locations of joints in the static model are captured. The Laplacian-based mesh contraction method with global positional constraints has been applied to obtain the skeletal shape of the model. Secondly, the correspondence relations between the joints and contracted mesh are established through K-nearest neighbors. Finally, some experiments have been performed to generate plausible kinematic skeletons on different 3D models. In addition, the correctness of the generated skeleton has been assessed by animating the skeleton. The animation of the obtained skeleton carried out through joint mapping by using 3D motion. The resulting skeletons could find its applications in 3D shape corresponding, shape interpolation mesh skinning, character animation and mesh editing.

Title: MONITORING OF ENVIRONMENT, HEALTH AND SOCIO-ECONOMIC IMPACTS OF LIMESTONE QUARRYING NEAR CHAKWAL, PAKISTAN Authors: Haseeb, Z; Rana, A.; Naseer, N.; Aftab, A.; Haseeb, A; Chaudhry, M.N.; Majid, M. Abstract: The limestone quarrying was occurring in the proposed study area. Environmental parameters, socio-economic and health impacts of quarrying were monitored. The noise level was comparatively high in the quarry area with the values ranging from 55 dB (A) to 89 dB (A).Similarly, surface water quality parameters, ground water quality parameters and ambient air quality was also monitored and compared with the NEQS values. PM10 was ranging from 139 to 187 µg/m3 , NO2 values from 58 to 87 µg/m3 , TDS value was 3675 mg/l and TSS was high with the value 230 mg/l. The socioeconomic status of the local residents was monitored and the health problems of the locals working and living near the site were also identified in which the main health issue is linked to dust. Dust problem and water shortage was the main problem of the area. Social issues and health problems were also linked to some of the parameters that were high.

Title: PERFORMANCE ANALYSIS OF 128-QAM DUAL POLARIZATION SYSTEM FOR LONG HAUL OPTICAL COMMUNICATION Authors: Sarwar, A. S.; Qamar, F.; Ahmad, M. S. Abstract: In order to deliver high data rate (content/applications) over the optical networks, higher order modulation schemes play a key role along with effective coding techniques. Quadrature Amplitude Modulation (QAM) technique is believed to be one of the vastly used modulation schemes for optical communication these days. Bandwidth utilization in higher order modulation schemes is more effective as compared to other modulation schemes. Performance of 128-QAM with dual polarization for long haul optical communication has been investigated in this paper. Investigation has been carried out at data rate of 112 Gbits/s for a fiber length of 100 Km. Simulation study enables to visualize constellation diagram, optical spectrum and optical signal in time domain. Different system impairments, such as dispersion and attenuation have also been combated by the use of Dispersion Compensation Fiber (DCF) and amplifiers.

Title: SPATIAL ANALYSIS FOR THE IDENTIFICATION OF HIGH-RISK LOCATIONS OF ROAD ACCIDENTS WITH PEDESTRIAN FATALITIES IN LAHORE Authors: Haseeb, A.; Saleemi, A.; Haseeb, Z.; Amin, S.; Islam, H. S Abstract: Lahore is facing a serious road safety threat due to the increase in road accidents and pedestrians are significantly exposed to the risk of injuries and fatalities. This paper intends to explore the high-risk accident locations with most pedestrian fatalities in Lahore which allows to specifically improve the pedestrian safety. In this research, 702 accidents involving pedestrian fatalities from 2012 to 2017 have been analyzed to determine the trends of pedestrian accidents in Lahore and learn the accident dense areas. These trends are spatially analyzed using Kernel Density Estimation (KDE), an application available in Geographic Information System (GIS), to identify the high-risk locations for pedestrians. The results reveal that most accidents occurred during the peak traffic hours faced largely by males and car is most used vehicle type with reckless driving as the main cause of the pedestrian accidents. The KDE analysis highlighted the high-risk locations for pedestrians which are considered busiest in the city accommodating large traffic volume. Pedestrian safety at these locations can be improved by the enforcement of traffic rules and provision of pedestrian infrastructure and education.
