One of the necessary infrastructure requirements for any a developed country is the construction of dams to generate power and providing water for irrigation purposes. Despite their necessity, however they pose a great risk to both human lives and infrastructure present in their vicinity e.g. roads, bridges, residential areas etc. If a dam collapsed in an area close to human population it could cause great havoc and economical loss. To diminish these hazards actions are being taken by studying different modes of dam failures and their subsequent effects downstream of the dam collapse. Numerical models are being made to simulate breaching of dams and effects downstream. This study focuses on the effects of a flood wave propagating on a fixed bed at the downstream side when the downstream side is open without presenting any obstruction to the flow. It is observed that the flood wave diminishes in velocity and height with increase in time. For downstream open condition the flood wave attains maximum height in1 to 4 sec and maximum velocity within 1 to 6 sec, whereas time taken for the wave to completely dissipate is 42 sec.</p> <p><strong><em>Key words</em></strong>: Dams; downstream open; flood wave; height; model; velocity</p> 2019-02-13T15:56:45+05:00 ##submission.copyrightStatement## http://tj.uettaxila.edu.pk/index.php/technical-journal/article/view/508 Performance of T-joints repaired with different CFRP arrangements 2019-02-13T16:19:53+05:00 Fiaz Tahir fiaz.tahir@uettaxila.edu.pk Saqib Mehboob syed.saqib@uettaxila.edu.pk Qaiser Uz Zaman Khan dr.qaiser@uettaxila.edu.pk Faisal Shabir faisal.shabbir@uettaxila.edu.pk <p>In this investigation, carbon fiber reinforced polymers (CFRP) were used to repair six damaged reinforced concrete (RC) beam-column T joints. Two different types of CFRP configurations (1 &amp; 2) were employed to reinstate the seismic capacity of joints. The specimens were tested under cyclic axial loading till failure. Load deflection relationships of tested specimens were used to draw hysteresis loops and backbone curves. In order to assess the seismic performance this data was then used to calculate energy dissipation values at selected intervals. Finite element modelling of all the three types was also done in ANSYS to validate model. It was concluded that seismic capacity of repaired specimen is affected by the CFRP configuration techniques. It was found that the relative energy dissipation capacity of specimens repaired with CFRP configuration-2 was 25.43% higher than CFRP configuration-1, and cumulative energy dissipation capacity was 5.24% higher in CFRP configuration-2 as compared to CFRP configuration-1. It was also found that the prevailing cracking pattern of repaired columns largely affects response of repaired specimen. Study also concluded that performance of Beam-column joints can be improved by appropriately selecting the CFRP configuration without altering other parameters.</p> 2019-02-13T12:53:22+05:00 ##submission.copyrightStatement## http://tj.uettaxila.edu.pk/index.php/technical-journal/article/view/633 A Frequency Domain analysis of Partial Discharge defects Patterns using Neural Network Model under Cryogenic Temperature 2019-02-13T16:20:11+05:00 Muhammad Yousaf Ali Khan myousafak@gu.edu.pk Javed Iqbal javediqbal.iet@gu.edu.pk Kashif Hussain Memon kashif.hussain@iub.edu.pk Umer Amir Khan dr.umeramir@cust.edu.pk Faizan Umar fumar.msee15seecs@seecs.edu.pk Zeeshan Kaleem zeeshankaleem@gmail.com <p>The superconducting equipment’s are used for enhancing the transmission capacity of the traditional electric power equipment’s. This is due to many technical advantages which are mostly related to its reduced size, weight, high efficiency and many more. Keeping in view of this fact, many researchers are carrying out experimental investigations to improve its performance which are mostly related to their reliability, when used under cryogenic conditions. One of the most important parameter which is used to describe the insulation status of the apparatus is Partial discharge (PD) detection. However, not many methods had been proposed for the results observed in cryogenic conditions. In current work, three different artificial defects, including protrusion, floating electrode, and turn to turn defects are put into Liquid nitrogen to create cryogenic conditions.&nbsp; To produce PD, AC voltage is applied to the apparatus. Pattern recognition of the PD signal which are detected based on CAPD method (Chaos analysis of PD). In order to improve the rate of PD pattern recognition which is able to classify different type of insulation defects introducible into the superconducting power apparatus, training data is added with the frequency spectrum data. Afterwards, the changes in Mean Square Error (MSE) and PD pattern recognition rate are compared by using the only CAPD data and CAPD data combined with frequency spectrum data.</p> 2019-02-13T13:11:20+05:00 ##submission.copyrightStatement## http://tj.uettaxila.edu.pk/index.php/technical-journal/article/view/533 Small size printed antenna using Defected Ground Structure 2019-02-13T16:20:31+05:00 Shahid Bashir shahid.bashir@uetpeshawar.edu.pk Faiz Ullah Engrfaiz379@gmail.com Amin Khan engr.amenkhan@gmail.com <p>A novel technique for designing small size printed antenna is proposed which is suitable for portable and multifunctional communication systems. Our proposed design consists of dielectric cylinders of high permittivity placed along the edges of patch and ground plane incorporating defected ground structure (DGS) with I-shaped, F–shaped and L-shaped slots. Size reduction of up to 66% as compared to conventional antenna has been obtained. The other key feature of this antenna is multiband band response in frequency range of 1-8GHz with good gain (3.5dB - 4.1dB) and improved impedance band width. This small size printed antenna can be used in mobile phone for WiMAX, GPS, WLAN and Bluetooth. All the simulations have been done using 3D EM tool CST MWS.</p> 2019-02-13T15:53:23+05:00 ##submission.copyrightStatement## http://tj.uettaxila.edu.pk/index.php/technical-journal/article/view/748 DEVELOPMENT OF A RADIATION-SEEKING ROBOT FOR LOCATING MISPLACED RADIATION SOURCES 2019-02-13T16:20:41+05:00 Jun Keat Lee jin_keat95@hotmail.com Dr. Nahrul Khair Bin Alang Md Rashid nahrulk@gmail.com <p><em>Locating misplaced radiation source is an important element in radiation industry.

The chaotic signals are generated with semiconductor laser and mathematically modeled by laser rate equation. The Gain flattening filter (GFF) is used with EDFA (Erbium Doped Fiber Amplifier) to uniformly amplify all the channels. The optimization of Gain Flattening Filter is done in chaotic environment to achieve the flattened gain profile of EDFA. The synchronization of chaos at transmitter and receiver is achieved to recover the received signal. Thus, our scheme combines two advantages i.e. efficient bandwidth utilization and security at the same time in DWDM communication model.</strong></p> 2019-02-13T14:28:00+05:00 ##submission.copyrightStatement## http://tj.uettaxila.edu.pk/index.php/technical-journal/article/view/472 Data Acquisition and Analysis Model for EGovernment 2019-02-13T16:21:19+05:00 AHSAN NAZIR ahsan_ravian@hotmail.com Amjad Farooq amjadfarooq@uet.edu.pk Tasawer Nawaz tasawernawaz@gmail.com Rizwan Abbas rizwan_uetian@outlook.com <p><strong>Abstract-</strong> e-Government technology has become major tool to facilitate citizens of a country and improve performance of a government. Some countries have successfully integrated it while others are still trying to incorporate it for the betterment of their governance. In this research, we explore existing web-based systems like social media and study how these systems are used for collecting data that can be utilized to improve governance. Then we propose and develop new system, which fetches data from common citizens regarding the performance of government, analyses that data and suggests how government agencies can use this data to improve their governance. In existing systems, government agencies can interact with common citizens in one way but using our developed system common citizens can also interact with them. Using our system government can collect data from common citizens and analyze this data for decision-making and good governance.</p> 2019-02-13T13:22:59+05:00 ##submission.copyrightStatement## http://tj.uettaxila.edu.pk/index.php/technical-journal/article/view/461 Comparison of OLSR and DSDV Routing Protocols in Wireless Sensor Network by Using NS-2 2019-02-13T16:21:29+05:00 Ayesha Tahir ayesha9154@yahoo.com Imran Mumtaz director.it@uaf.edu.pk Mudassar Ahmed muddassar.utm@gmail.com Muhammad Munwar Iqbal munwar89@gmil.com Muhammad Tahir Mehmood mtahirishere@outlook.com <p><em>The wireless sensor networks consist of large amount of small sensor nodes that can process, store and transmit data within limited range because of their small size and minimum cost these nodes with embedded sensors are widely use in different type of applications such as tracking and health monitoring.

For routing the data different protocols were used that can guarantee the communication and maintaining the paths in network. I have compared the two routing protocols OLSR and DSDV in wireless sensor network. I have compare the three-metrics throughput, average end to end delay and latency of these two protocols with different packet size and make the three types of scenarios with respect to bandwidth in ns 2. The results show that the DSDV has high throughput, low latency and low average end to end delay as compare to OLSR that shows minimum throughput, high average end to end delay and has high latency to transmit data in all the scenarios.</em></p> 2019-02-13T00:00:00+05:00 ##submission.copyrightStatement## http://tj.uettaxila.edu.pk/index.php/technical-journal/article/view/596 Matching Based Algorithm for Semantic Search and its Implementation 2019-02-13T16:21:46+05:00 Syed Muhammad Adnan syedadnanshah@gmail.com Tehreem Fatima tehreemfatimagondal@gmail.com Ume Habiba umehabiba555@gmail.com Muhammad Ilyas m.ilyas@uos.edu.pk Syed M Adnan syed.adnan@uettaxila.edu.pk Wakeel Ahmad wakeel.ahmad@uettaxila.edu.pk Junaid Rashid junaidrashid062@gmail.com <p>With rapidly increasing information and data available online, end users are not satisfied with search results of even renowned search engines. Most of the time search engines results in irrelevant pages to the users. Semantic search aims to improve&nbsp; search results by retrieving data on the basis of keywords and its synonyms as well. It focuses on intent and context of query. Semantic search is also used to get variety in results. This research work discuss and compare architecture of various semantic search engines based on how much semantics they include in their results.

Khan mnak2010@gmail.com Muhammad Fayaz hamaz_khan@yahoo.com Muhammad Munwar Iqbal munwar89@gmil.com <p>This research presents an intelligent methodology for classification of brain MRI. Our suggested methodology comprises on four stages, such as pre-processing, feature extraction, feature reduction, and classification. In the first stage, a median filter is applied on brain MRI to remove the noise and then converted this image to RGB. In the second stage, discrete wavelet transform (DWT) is used for feature extraction from the image. However, the number of extracted features is still very high which is further reduced in the third namely feature reduction stage using color moments, which is our main contribution. Finally, in the last stage of methodology, the reduced features are sent to k-Nearest Neighbors (k-NN) to classify the normality and abnormality of brain MRI. The overall accuracy of our suggested method is almost 94.9745%.</p> 2019-02-13T15:59:43+05:00 ##submission.copyrightStatement## http://tj.uettaxila.edu.pk/index.php/technical-journal/article/view/704 Picture Hesitant Fuzzy Set and its Applications 2019-02-13T16:22:18+05:00 Kifayat Ullah kifayat.phdma72@iiu.edu.pk Zeeshan Ali zeeshanalicheema93@gmail.com Naeem Jan naeem.phdma73@iiu.edu.pk Tahir Mahmood tahirbakhat@iiu.edu.pk Shahid Maqsood smaqsood@uetpeshawar.edu.pk <p>In this work, we proposed the theory of picture hesitant fuzzy set (PHFS) as a generalization of picture fuzzy set (PFS) and hesitant fuzzy set (HFS).
