Intelligent High Resolution Satellite/Aerial Imagery  [PDF]
Nadeem Fareed
Advances in Remote Sensing (ARS) , 2014, DOI: 10.4236/ars.2014.31001
Abstract:


High resolution satellite images are rich source of geospatial information. Nowadays, these images contain finest spectral and spatial information of ground realities in different electromagnetic spectrum. Many image processing softwares, algorithms and techniques are available to extract such information from these images. Multi spectral as well as panchromatic (PAN) high resolution satellite images are missing, one important information, regarding ground features and realities that information is attribute information which is not directly available in high resolution satellite images. From very first day, this information used to be collected through indirect ways using GPS, digitizing, geo-coding, geo tagging, field survey and many other techniques. Our real world has vertical labels for ground observer to identify and use this information. These vertical labels are present in form of names, logos, icons, symbols and numbers. These vertical labels ease us to work in real world. Satellites are unable to read these labels due to their vertical orientation. Making satellite/aerial imagery rich of attribute information, we have the possibility to design our world accordingly. Just like vertical labels we can also place real physical horizontal label for space sensors, to make this information directly available in high resolution satellite/aerial imagery. This work is about possibilities of such techniques and methods.



Bonded Labour in Pakistan  [PDF]
Nadeem Malik
Advances in Anthropology (AA) , 2016, DOI: 10.4236/aa.2016.64012
Abstract: Bonded labour is widespread in Pakistan. This paper is an attempt to illustrate the nature of bonded labour in the agricultural sector and the brick kiln industry in the country. Despite the introduction of Bonded Labour System (Abolition) Act 1992, bonded labour thrives because of the power and influence of big landlords in rural and factory owners in urban localities. It is argued that without effective land reforms or land distribution bonded labour cannot be eliminated. In additional to land reforms, effective governance based on strong democratic culture free of the influence of big landowners is essential to address the issue of bonded labour in Pakistan.
Q-LEACH: A New Routing Protocol for WSNs
B. Manzoor,N. Javaid,O. Rehman,M. Akbar,Q. Nadeem,A. Iqbal,M. Ishfaq
Computer Science , 2013,
Abstract: Wireless Sensor Networks (WSNs) with their dynamic applications gained a tremendous attention of researchers. Constant monitoring of critical situations attracted researchers to utilize WSNs at vast platforms. The main focus in WSNs is to enhance network life-time as much as one could, for efficient and optimal utilization of resources. Different approaches based upon clustering are proposed for optimum functionality. Network life-time is always related with energy of sensor nodes deployed at remote areas for constant and fault tolerant monitoring. In this work, we propose Quadrature-LEACH (Q-LEACH) for homogenous networks which enhances stability period, network life-time and throughput quiet significantly.
M-GEAR: Gateway-Based Energy-Aware Multi-Hop Routing Protocol for WSNs
Q. Nadeem,M. B. Rasheed,N. Javaid,Z. A. Khan,Y. Maqsood,A. Din
Computer Science , 2013,
Abstract: In this research work, we advise gateway based energy-efficient routing protocol (M-GEAR) for Wireless Sensor Networks (WSNs). We divide the sensor nodes into four logical regions on the basis of their location in the sensing field. We install Base Station (BS) out of the sensing area and a gateway node at the centre of the sensing area. If the distance of a sensor node from BS or gateway is less than predefined distance threshold, the node uses direct communication. We divide the rest of nodes into two equal regions whose distance is beyond the threshold distance. We select cluster heads (CHs)in each region which are independent of the other region. These CHs are selected on the basis of a probability. We compare performance of our protocol with LEACH (Low Energy Adaptive Clustering Hierarchy). Performance analysis and compared statistic results show that our proposed protocol perform well in terms of energy consumption and network lifetime.
SIMPLE: Stable Increased-throughput Multi-hop Protocol for Link Efficiency in Wireless Body Area Networks
Q. Nadeem,N. Javaid,S. N. Mohammad,M. Y. Khan,S. Sarfraz,M. Gull
Computer Science , 2013,
Abstract: In this work, we propose a reliable, power efficient and high throughput routing protocol for Wireless Body Area Networks (WBANs). We use multi-hop topology to achieve minimum energy consumption and longer network lifetime. We propose a cost function to select parent node or forwarder. Proposed cost function selects a parent node which has high residual energy and minimum distance to sink. Residual energy parameter balances the energy consumption among the sensor nodes while distance parameter ensures successful packet delivery to sink. Simulation results show that our proposed protocol maximize the network stability period and nodes stay alive for longer period. Longer stability period contributes high packet delivery to sink which is major interest for continuous patient monitoring.
Timed-Automata Based Model-Checking of a Multi-Agent System: A Case Study  [PDF]
Nadeem Akhtar, Muhammad Nauman
Journal of Software Engineering and Applications (JSEA) , 2015, DOI: 10.4236/jsea.2015.82006
Abstract: A multi-agent based transport system is modeled by timed automata model extended with clock variables. The correctness properties of safety and liveness of this model are verified by timed automata based UPPAAL. Agents have a degree of control on their own actions, have their own threads of control, and under some circumstances they are also able to take decisions. Therefore they are autonomous. The multi-agent system is modeled as a network of timed automata based agents supported by clock variables. The representation of agent requirements based on mathematics is helpful in precise and unambiguous specifications, thereby ensuring correctness. This formal representation of requirements provides a way for logical reasoning about the artifacts produced. We can be systematic and precise in assessing correctness by rigorously specifying the functional requirements.
Frequency of Depression and Anxiety among Tuberculosis Patients  [PDF]
  Amreen, Nadeem Rizvi
Journal of Tuberculosis Research (JTR) , 2016, DOI: 10.4236/jtr.2016.44021
Abstract: Objective: The aim of present study was to determine the frequency of depression and anxiety among tuberculosis patients. Methods: It was a descriptive study that had investigated the co-morbidity of depression and anxiety among tuberculosis patients with reference to gender. This study was conducted in Jinnah Post Graduate Medical Centre—Chest ward (TB clinic) from July 2014 to September 2014. Hundred diagnosed patients of tuberculosis (50 males and 50 females) were randomly selected. Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder Questionnaire (GAD-7) were used to assess the level of anxiety and depression. Results: Findings indicated that 56% tuberculosis (TB) patients had moderate to severe level of depression, whereas 65% TB patients had moderate to severe level of anxiety. Female patients had significantly high prevalence of depression as compared to males (t = 2.173, P < 0.05). Similarly, prevalence of anxiety was also significantly higher in female patients (t = 3.468, P < 0.05). Conclusion: Likelihood of depression and anxiety was frequent in tuberculosis patients. However, better management of these psychiatric morbidities may improve treatment adherence, illness perception and patient coping skills.
Nontraumatic terminal ileal perforation
Rauf A Wani, Fazl Q Parray, Nadeem A Bhat, Mehmood A Wani, Tasaduq H Bhat, Fowzia Farzana
World Journal of Emergency Surgery , 2006, DOI: 10.1186/1749-7922-1-7
Abstract: This study was a prospective study aimed at evaluating the clinical profile, etiology and optimal surgical management of patients with nontraumatic terminal ileal perforation.There were 79 cases of nontraumatic terminal ileal perforation; the causes for perforation were enteric fever(62%), nonspecific inflammation(26%), obstruction(6%), tuberculosis(4%) and radiation enteritis (1%). Simple closure of the perforation (49%) and end to side ileotransverse anastomosis(42%) were the mainstay of the surgical management.Terminal ileal perforation should be suspected in all cases of peritonitis especially in developing countries and surgical treatment should be optimized taking various accounts like etiology, delay in surgery and operative findings into consideration to reduce the incidence of deadly complications like fecal fistula.Perforation of the bowel especially the typhoid perforation is a serious complication and remains a significant surgical problem in developing nations. It is usually associated with high mortality and morbidity as it occurs mostly in underdeveloped countries in places where medical facilities are not readily available. Perforation of terminal ileum is a cause for obscure peritonitis, heralded by exacerbation of abdominal pain associated with tenderness, rigidity and guarding, most pronounced over right iliac fossa. However for many patients in a severe toxic state, there may be obscured clinical features with resultant delays in diagnosis and adequate surgical intervention[1].The present study was taken to review our experience of clinical profile and management of terminal ileal perforation over past 7 years.The present study was a prospective study conducted by Department of General Surgery, Sher-i-Kashmir Institute of Medical Sciences, Srinagar from January 1999 to July 2005. All the patients were admitted in Accident & Emergency deptt. A thorough history was taken and detailed examination done as per proforma. Baseline investigations include
Utilization of Industrial Waste Slag as Aggregate in Concrete Applications by Adopting Taguchi’s Approach for Optimization  [PDF]
Mohammed Nadeem, Arun D. Pofale
Open Journal of Civil Engineering (OJCE) , 2012, DOI: 10.4236/ojce.2012.23015
Abstract: This paper presents result of an experimental investigation carried out to evaluate effects of replacing aggregates (coarse & fine) with that of Slag (Crystallized & Granular) which is an industrial waste by-product on concrete strength properties by using Taguchi’s approach of optimization. Whole study was done in three phases, in the first phase natural coarse aggregate was replaced by crystallized slag coarse aggregate keeping fine aggregate (natural sand) common in all the mixes, in the second phase fine aggregate (natural sand) was replaced by granular slag keeping natural coarse aggregate common in all the mixes and in the third phase both the aggregates were replaced by crystallized & granular aggregates. The study concluded that compressive strength of concrete improved almost all the % replacements of normal crushed coarse aggregate with crystallized slag by 5% to 7%. In case of replacements of fine aggregate and both type of aggregates, the strength improvements were notably noticed at 30% to 50% replacement level. It could also be said that full substitution of slag aggregate with normal crushed coarse aggregate improved the flexure and split tensile strength by 6% to 8% at all replacements and in case of replacing fine aggregate & both the aggregates( Fine & coarse) with slag, the strength improvement was at 30% to 50% replacements. It is evident from the investigation that Taguchi approach for optimization helped in indentifying the factors affecting the final outcomes. Based on the overall observations, it could be recommended that Slag could be effectively utilized as coarse & fine aggregates in all concrete applications.
Camera Localization in Distributed Networks Using Trajectory Estimation
Nadeem Anjum
Journal of Electrical and Computer Engineering , 2011, DOI: 10.1155/2011/604647
Abstract: This paper presents an algorithm for camera localization using trajectory estimation (CLUTE) in a distributed network of nonoverlapping cameras. The algorithm recovers the extrinsic calibration parameters, namely, the relative position and orientation of the camera network on a common ground plane coordinate system. We first model the observed trajectories in each camera's field of view using Kalman filtering, then we use this information to estimate the missing trajectory information in the unobserved areas by fusing the results of a forward and backward linear regression estimation from adjacent cameras. These estimated trajectories are then filtered and used to recover the relative position and orientation of the cameras by analyzing the estimated and observed exit and entry points of an object in each camera's field of view. The final configuration of the network is established by considering one camera as a reference and by adjusting the remaining cameras with respect to this reference. We demonstrate the algorithm on both simulated and real data and compare the results with state-of-the-art approaches. The experimental results show that the proposed algorithm is more robust to noisy and missing data and in case of camera failure.
