In this case, the temperature control becomes a critical objective. This research work presents the temperature control of the double-pipe heat exchanger (multi-input multi-output (MIMO) system), which is modeled as first-order coupled hyperbolic partial differential equations (PDEs), using conventional and advanced control techniques and develops appropriate robust control strategy to meet stability requirements and performance objectives. We designed a PID controller and H-infinity controller for a heat exchanger (HE) system. Frequency characteristics of sensitivity functions and open-loop and closed-loop time responses are simulated using MATLAB software, and the stability of the system is analyzed using Kalman's test. The simulation results have demonstrated that the H-infinity controller is more efficient than PID in terms of robustness and performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20exchanger" title="heat exchanger">heat exchanger</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-input%20multi-output%20system" title=" multi-input multi-output system"> multi-input multi-output system</a>, <a href="https://publications.waset.org/abstracts/search?q=MATLAB%20simulation" title=" MATLAB simulation"> MATLAB simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=partial%20differential%20equations" title=" partial differential equations"> partial differential equations</a>, <a href="https://publications.waset.org/abstracts/search?q=PID%20controller" title=" PID controller"> PID controller</a>, <a href="https://publications.waset.org/abstracts/search?q=robust%20control" title=" robust control"> robust control</a> </p> <a href="https://publications.waset.org/abstracts/138748/comparison-of-conventional-control-and-robust-control-on-double-pipe-heat-exchanger" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138748.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">220</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">101</span> Co-Evolutionary Fruit Fly Optimization Algorithm and Firefly Algorithm for Solving Unconstrained Optimization Problems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20M.%20Rizk-Allah">R.

This paper examines her influence on three Lebanese women writers: Emily Nasrallah, Muná Jabbūr, and Hanan al-Shaykh. However, the aim is not simply to examine the influence of the writer on these three authors, but rather to note similarities and differences in the challenges they faced and the agendas they followed in their fiction writing. For each of these writers, this article will describe elements of their literature, and then sketch out the influence which Ba'albakī has had on them. This paper relies on material from Sidawi because it includes interviews with the female writers discussed that are relevant to the current discussion. Sidawi asked them about Ba'albakī and her influence on them, the challenges they faced, and how they coped with them. This paper points out their comments using their own words. To be clear, examining these writers' notes and works is beyond the scope of this paper. To sum up, there are significant parallels between the life and work of Ba'albakī, and other Lebanese women writers such as Nasrallah, Jabbūr and al-Shaykh. Like Ba'albakī, Nasrallah and al-Shaykh also suffered in their struggle against their families. Nasrallah and al-Shaykh, like Ba'albakī, suffered because their society did not trust in their abilities and creativity. Ba'albakī opted for isolation because of her conflict with patriarchal society including the Lebanese women’s groups, while Nasrallah's isolation was because she preferred individualism and autonomy, and Jabbūr, as could be speculated, was not able to cope with the suffering caused by her role as a woman writer within Lebanese society. Whereas Ba'albakī isolated herself from the Lebanese women’s groups, focusing instead on her feminist writing and joining the Shi'r group, Al-Shaykh and the Lebanese women’s groups are able to cooperate in harmony. Furthermore, while Nasrallah and Al-Shaykh continued to publish fiction, Ba'albakī stopped publishing fiction in 1964. All of the above confirms not only that it is worthy to investigate deeply and academically both the biography and the works of Ba'albakī, but also that she deserves to include her throughout the top great Arab female writers, at the time, like Al-Shaykh and Nawal El Saadawi. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=feminist%20writing" title="feminist writing">feminist writing</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Al-Shaykh" title=" Hanan Al-Shaykh"> Hanan Al-Shaykh</a>, <a href="https://publications.waset.org/abstracts/search?q=Layl%C3%A1%20Ba%27albak%C4%AB" title=" Laylá Ba'albakī"> Laylá Ba'albakī</a>, <a href="https://publications.waset.org/abstracts/search?q=Lebanese%20women%20writers" title=" Lebanese women writers"> Lebanese women writers</a>, <a href="https://publications.waset.org/abstracts/search?q=Mun%C3%A1%20Jabb%C5%ABr" title=" Muná Jabbūr"> Muná Jabbūr</a> </p> <a href="https://publications.waset.org/abstracts/48811/baalbakis-influence-on-1950s-and-1960s-lebanese-women-writers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48811.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">332</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">97</span> Efficient Control of Brushless DC Motors with Pulse Width Modulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Shahzadi">S.

To implement this practically the Atmel’s AVR ATmega 328 microcontroller embedded on an Arduino Eleven board is utilized. The microcontroller programming is done in an open source Arduino IDE development environment. The programming logic effectively manipulated a six MOSFET bridge which was used to energize the stator windings as per control requirements. The results obtained showed accurate, precise and efficient pulse width modulated operation. Another advantage offered by this pulse width modulated control was the efficient speed control of the motor. By varying the time intervals between successive commutations, faster energizing of the stator windings was possible thereby leading to quicker rotor alignment with these energized phases and faster revolutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brushless%20DC%20motors" title="brushless DC motors">brushless DC motors</a>, <a href="https://publications.waset.org/abstracts/search?q=commutation" title=" commutation"> commutation</a>, <a href="https://publications.waset.org/abstracts/search?q=MOSFET" title=" MOSFET"> MOSFET</a>, <a href="https://publications.waset.org/abstracts/search?q=PWM" title=" PWM"> PWM</a> </p> <a href="https://publications.waset.org/abstracts/32239/efficient-control-of-brushless-dc-motors-with-pulse-width-modulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32239.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">512</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">96</span> Basic Evaluation for Polyetherimide Membrane Using Spectroscopy Techniques </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Alenezi">Hanan Alenezi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Membrane performance depends on the kind of solvent used in preparation.

More than 90% of esophageal cancers are either squamous cell carcinoma or adenocarcinoma. Squamous dysplasia is a precancerous lesion for squamous cell carcinoma and Barrett's esophagus is the precancerous lesion for adenocarcinoma. Gastro-esophageal reflux disease (GERD) is the initiation factor for Barrett's esophagus. Cyclooxygenase-2 (COX-2) is a key enzyme in arachidonic metabolism. It appears to play an important role in gastrointestinal carcinogenesis. COX-2 activity may be a potential target for the prevention of cancer progression by selective COX-2 inhibitors, which decrease proliferation and increase apoptosis. Objectives To assess COX-2 expression in premalignant and malignant esophageal epitheliums changes and detect its roles in progression of these lesions. Materials and Methods We analyzed the expression of COX-2 immunohistochemically in 40 esophageal biopsies utilizing the streptavidin-biotin-peroxidase complex method on archival formalin fixed-paraffin embedded blocks. Histopathologically, 17 (42.5%) of cases were non-malignant cases which included GERD, Barrett's esophagus and squamous dysplasia. The malignant cases were 23 (57.5%) squamous cell carcinoma, adenocarcinoma and undifferentiated carcinoma. Results In non-malignant cases 7 (41.2%) out of 17 cases had high COX-2 expression. In squamous cell carcinoma 10 (83.3%) out of 12 cases had high COX-2 expression. The expression of COX-2 was high in all 9 (100%) cases of adenocarcinoma. COX-2 expression is significantly increased (P=0.005 and P=0.0001) in squamous cell carcinoma and adenocarcinoma respectively. There was a significant difference in COX-2 immunoreactivity between malignant and non-malignant lesions (P=0.0003). Conclusion COX-2 is responsible for the progression of esophageal diseases from benign to malignant. We recommend that COX-2 immunohistochemistry should be done routinely for premalignant and malignant esophageal lesions as selective COX-2 inhibitors will be helpful in the treatment. Further studies on molecular and genetic basis of COX-2 expression are needed to unmask its role and relation to progression of esophageal lesions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cox-2" title="Cox-2">Cox-2</a>, <a href="https://publications.waset.org/abstracts/search?q=Esophageal%20adinocarcinoma" title=" Esophageal adinocarcinoma"> Esophageal adinocarcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Esophageal%20squamous%20cell%20carcinoma" title=" Esophageal squamous cell carcinoma"> Esophageal squamous cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Immunohistochemistry." title=" Immunohistochemistry.

Also, it has been shown recently that it may have cancer inhibiting effect. The primary antibabesial effect of Enoxacin is due to inhibition of DNA gyrase subunit A, and DNA topoisomerase. In the present study, enoxacin was tested as a potent inhibitor against the in vitro growth of bovine and equine Piroplasms. The in vitro growth of five Babesia species that were tested was significantly inhibited (P<0.05) by micromolar concentrations of enoxacin (IC50 values= 13.5, 7.2, 7.5, and 24.2 µM for Babesia bovis, Babesia bigemina, Babesia caballi, and Theileria equi, respectively). Enoxacin IC50 values for Babesia and Theileria parasites were satisfactory as the drug is a potent antibacterial drug with minimum side effects. Therefore, enoxacin might be used for the treatment of Babesiosis and Theileriosis especially in case of mixed infections with bacterial diseases or in the case of animal sensitivity against diminazin toxicity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enoxacin" title="enoxacin">enoxacin</a>, <a href="https://publications.waset.org/abstracts/search?q=Babesia" title=" Babesia"> Babesia</a>, <a href="https://publications.waset.org/abstracts/search?q=Theileria" title=" Theileria"> Theileria</a>, <a href="https://publications.waset.org/abstracts/search?q=IC50%20and%20dimenazin" title=" IC50 and dimenazin"> IC50 and dimenazin</a> </p> <a href="https://publications.waset.org/abstracts/24342/evaluation-of-in-vitro-inhibitory-effect-of-enoxacin-on-babesia-and-theileria-parasites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24342.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">468</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">89</span> Calibrations and Effect of Different Operating Conditions on the Performance of a Fluid Power Control System with Servo Solenoid Valve</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tahany%20W.%20Sadak">Tahany W.

Advanced methods have been used to measure and record laboratory experiments, to ensure accurate analysis and evaluation. Experiments have been conducted under different values of temperature (28, 40 and 50 °C), supply pressure (10, 20, 30, 40 and 50 bar), system stiffness (32 N/mm), and load (0.0 & 5560 N). It is concluded that increasing temperature of hydraulic oil increases the quantity of flow rate, so it achieves an increase of the quantity of flow by 5.75 % up to 48.8 % depending on operating conditions. The values of pressure decay at low temperature are less than the values at high temperature. The frequency increases with the increase of the temperature. When we connect the springs to the system, it decreases system frequency. These results are very useful in the process of packing and manufacturing of fluid products, where the properties are not affected by 50 °C, so energy and time are saved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electro-hydraulic%20servo%20valve" title="electro-hydraulic servo valve">electro-hydraulic servo valve</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid%20power%20control%20system" title=" fluid power control system"> fluid power control system</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20stiffness" title=" system stiffness"> system stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20and%20dynamic%20performance" title=" static and dynamic performance"> static and dynamic performance</a> </p> <a href="https://publications.waset.org/abstracts/98470/calibrations-and-effect-of-different-operating-conditions-on-the-performance-of-a-fluid-power-control-system-with-servo-solenoid-valve" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98470.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">88</span> Turing Pattern in the Oregonator Revisited</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elragig%20Aiman">Elragig Aiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Dreiwi%20Hanan"> Dreiwi Hanan</a>, <a href="https://publications.waset.org/abstracts/search?q=Townley%20Stuart"> Townley Stuart</a>, <a href="https://publications.waset.org/abstracts/search?q=Elmabrook%20Idriss"> Elmabrook Idriss</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we reconsider the analysis of the Oregonator model.

The use of these materials may add to the initial cost of construction. However, the life cycle (cradle to grave) cost of houses using these construction materials and methods are lower than the life cycle costs using traditional housing construction materials and methods. This paper will present four (4) case studies of sustainable house projects. Each project was designed and constructed using earthen-based, sustainable fiberboard material that is resistant to fire, mold, and infestation and fabricated at a very low material calorific value. These house projects have a living space ranging from 625 sq. ft. for an accessory dwelling unit and up to 3,200 sq. ft. 1-story and 2-story homes. For each case study, we will present the house engineering design and construction method, the initial construction costs, a summary of the life cycle costs, and a comparison to the life cycle cost of traditional housing available in the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=residential%20housing" title="residential housing">residential housing</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20housing" title=" sustainable housing"> sustainable housing</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20cost" title=" life cycle cost"> life cycle cost</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20resistance" title=" fire resistance"> fire resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=mold" title=" mold"> mold</a>, <a href="https://publications.waset.org/abstracts/search?q=infestation%20resistance" title=" infestation resistance"> infestation resistance</a> </p> <a href="https://publications.waset.org/abstracts/151099/affordable-and-sustainable-housing-construction-case-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151099.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">84</span> Hardware Co-Simulation Based Based Direct Torque Control for Induction Motor Drive</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Mikhael%20Dawood">Hanan Mikhael Dawood</a>, <a href="https://publications.waset.org/abstracts/search?q=Haider%20Salim"> Haider Salim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jafar%20Al-Wash"> Jafar Al-Wash</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents Proportional-Integral (PI) controller to improve the system performance which gives better torque and flux response.

Consequently, numerous usability evaluation methods have been developed. However, the availability of large variety of evaluation methods alongside insufficient studies that critically analyse them resulted in an ambiguous process of selection amongst non-usability-expert practitioners. This study investigates the factors affecting the selection of usability evaluation methods within a project by interviewing a software development team. The results of the data gathered are then analysed and integrated in developing a framework. The framework developed poses a solution to the selection processes of usability evaluation methods by adjusting to individual projects resources and goals. It has the potential to be further evaluated to verify its applicability and usability within the domain of this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=usability%20evaluation" title="usability evaluation">usability evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=evaluating%20usability%20in%20non-user%20entered%20designs" title=" evaluating usability in non-user entered designs"> evaluating usability in non-user entered designs</a>, <a href="https://publications.waset.org/abstracts/search?q=usability%20evaluation%20methods%20%28UEM%29" title=" usability evaluation methods (UEM)"> usability evaluation methods (UEM)</a>, <a href="https://publications.waset.org/abstracts/search?q=usability%20evaluation%20in%20projects" title=" usability evaluation in projects"> usability evaluation in projects</a> </p> <a href="https://publications.waset.org/abstracts/122850/usability-evaluation-in-practice-selecting-the-appropriate-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122850.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">81</span> Electroencephalogram Signals Controlling a Parallax Boe-Bot Robot </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nema%20M.%20Salem">Nema M.

Apart from motor neuroprosthetics, many studies showed the possibility of controlling a virtual environment of a videogame using the acquired electroencephalogram signals (EEG) from the gamer. In addition, another study had successfully moved a farm tractor using the human’s EEG signals. This article utilizes the use of EEG signals, as a source of technology, in controlling a Parallax Boe-Bot robot. The commercial Emotive Epoc headset has been used in acquiring the EEG signals from rested subjects. Because the human's visual cortex can successfully differentiate between different colors, the red and green colors are used as visual stimuli for generating EEG signals using the Epoc. Arduino and Labview are used to translate the virtually pressed keys into instructions controlling the motion and rotation of the robot. Optimistic results have been achieved except for minor delay and accuracy in the robot’s response. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BCI" title="BCI">BCI</a>, <a href="https://publications.waset.org/abstracts/search?q=Emotiv%20Epoc%20headset" title=" Emotiv Epoc headset"> Emotiv Epoc headset</a>, <a href="https://publications.waset.org/abstracts/search?q=EEG" title=" EEG"> EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=Labview" title=" Labview"> Labview</a>, <a href="https://publications.waset.org/abstracts/search?q=Arduino%20applications" title=" Arduino applications"> Arduino applications</a>, <a href="https://publications.waset.org/abstracts/search?q=robot" title=" robot"> robot</a> </p> <a href="https://publications.waset.org/abstracts/19505/electroencephalogram-signals-controlling-a-parallax-boe-bot-robot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19505.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">522</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">80</span> Effectuation of Interactive Advertising: An Empirical Study on Egyptian Tourism Advertising</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bassant%20Eyada">Bassant Eyada</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Atef%20Kamal%20Eldin"> Hanan Atef Kamal Eldin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Advertising has witnessed a diffusion and development in technology to promote products and services, increasingly relying on the interactivity between the consumer and the advertisement.

The objective of this study is investigating either the effect of individual or combined doses of idebenone, carnosine and vitamin E on amelioration of some biochemical indices of nano sized titanium dioxide (TiO2 NPS) induced metabolic disorders in mice liver. TiO2-NPS was administered in an oral dose of 150 mg/kg for consecutive 14 days followed by oral daily doses of the aforementioned antioxidants for 1 month. TiO2-NPS induced a significant elevation in serum level of ALT and AST, hepatic inflammatory markers (tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)) and increased the percent of DNA damage which was assessed by COMET assay in addition to the apoptotic marker Caspase-3. Moreover, mRNA gene expression observed by RT-PCR showed a significant overexpression in nuclear factor relation-2 (Nrf2), nuclear factor kappa beta (NF-Kβ) and the apoptotic factor (bax), and a significant down-regulation in the antiapoptotic factor (bcl2) level. In conclusion, idebenone, carnosine and vitamin E ameliorated the deviated parameters with a variable degree with the most pronounced role in alleviating the hazardous effect of TiO2 NPS toxicity following the combination regimen. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=idebenone" title="idebenone">idebenone</a>, <a href="https://publications.waset.org/abstracts/search?q=carnosine" title=" carnosine"> carnosine</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20E" title=" vitamin E"> vitamin E</a>, <a href="https://publications.waset.org/abstracts/search?q=TiO2%20NPS" title=" TiO2 NPS"> TiO2 NPS</a>, <a href="https://publications.waset.org/abstracts/search?q=caspase-3" title=" caspase-3"> caspase-3</a>, <a href="https://publications.waset.org/abstracts/search?q=NrF2" title=" NrF2"> NrF2</a>, <a href="https://publications.waset.org/abstracts/search?q=NF-KB" title=" NF-KB"> NF-KB</a> </p> <a href="https://publications.waset.org/abstracts/7223/amelioration-of-over-expression-of-bax-nrf2-and-nfk-v-in-nano-sized-titanium-dioxide-intoxicated-mice-by-potent-antioxidants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7223.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">386</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">74</span> Diagnostic Evaluation of Urinary Angiogenin (ANG) and Clusterin (CLU) as Biomarker for Bladder Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marwa%20I.%20Shabayek">Marwa I.

Both cystoscopy and urine cytology used in detecting bladder cancer suffer from drawbacks where cystoscopy is an invasive method and urine cytology shows low sensitivity in low grade tumors. This study validates easier and less time-consuming techniques to evaluate the value of combined use of angiogenin and clusterin in comparison and combination with voided urine cytology in the detection of bladder cancer patients. This study includes malignant (bladder cancer patients, n= 50), benign (n=20), and healthy (n=20) groups. The studied groups were subjected to cystoscopic examination, detection of bilharzial antibodies, urine cytology, and estimation of urinary angiogenin and clusterin by ELISA. The overall sensitivity and specifcity were 66% and 75% for angiogenin, 70% and 82.5% for clusterin and 46% and 80% for voided urine cytology.

The standard image registration techniques such as Mutual information/ Normalized mutual information -based methods have a limited performance because they do not consider the spatial information or the relationships between the neighbouring pixels or voxels. In addition, the amount of image noise may significantly affect the registration accuracy. Therefore, this paper proposes an efficient method that explicitly considers the relationships between the adjacent pixels, where the gradient information of the reference and scene images is extracted first, and then the cosine similarity of the extracted gradient information is computed and used to improve the accuracy of the standard normalized mutual information measure. Our experimental results on different data types (i.e. CT, MRI and thermal images) show that the proposed method outperforms a number of image registration techniques in terms of the accuracy. <p
